Which pump is best for plate and frame filter press

YBH pump is a pressure-sensitive variable pump specially designed for plate and frame filter press feeding, mainly suitable for the sewage treatment industry when the filtration time is more than 30 minutes when feeding the filter press. The pump is adjustable constant pressure and automatic variable type.

To understand the performance of the special energy-saving pump of the YBH filter press, first understand the filtration characteristics of the filter press:

1. Feeding stage: When the feed is started, the filter chamber of the filter press is empty, and it needs to be filled with materials quickly. (YBH pump high flow feed quickly fills the filter press).

2. Booster filtration stage: when the pressure of the filter press is filled with material and begins to rise, the filter press quickly discharges water, and the filter press still needs a large flow of feeding. With the gradual increase of feed pressure, the filter cake in the high-pressure filter begins to thicken, the water output of the filter press begins to change from large to small, and the filtration capacity of the filter press also changes from large to small, and the feed amount also decreases.

The output flow of YBH pump automatically changes from large to small, and the hydraulic system has no overflow and starts energy-saving operation).

3. Pressure holding filtration stage: the filtration pressure of the filter press rises to the highest set pressure, and the feed pressure needs to be kept at constant pressure filtration, and the filtration capacity of the filter press is further reduced until the filtration is completed. (The YBH pump flow rate is reduced to a minimum and the constant pressure feed is maintained, and the hydraulic system has a very small amount of overflow).

When the pump begins to feed the filter press and filter at low pressure, the large flow rate remains unchanged, as the pressure of the filter press cavity is filled with material, the filtration capacity of the filter press begins to decrease, and when the set value is reached, the hydraulic system controls the running speed of the YBH pump to decrease and the output flow rate becomes smaller. The filtration energy of the filter press gradually decreases, the feed pressure gradually increases, the feed flow rate of the pump automatically decreases, the minimum flow rate is 20% of the rated flow, and the output flow pressure curve of the pump is basically consistent with the best filtration curve of the filter press. Therefore, the whole process is highly efficient and energy-saving, and it is more than 60% more energy-saving than ordinary pumps.

This should be selected according to the filtered material and the feed filter press, and the pump selected for the material that is not used is also different. You can find Li Ning of Jingxing Filter Press Accessories Company in Jingxian County, he is more professional.

In fact, it is difficult to judge whether the manufacturer is good or not on the Internet, and there are several measurement standards that can be used as a reference.

Whether it is a sales company: many environmental protection companies promote the sale of filter presses online or offline under the banner of manufacturers, many of them do not even have a fixed manufacturer, and the customer places an order after the cycle price comparison, and the general purchase is small factory equipment, with low cost and unstable quality;

Whether it has the ability to produce large-scale equipment: The manufacturers that can produce large-scale filter presses are all manufacturers with excellent technology in the industry, and most companies can only produce equipment below 1500m at most. If it can produce a filter press like 2000m, it means that the manufacturer's strength and technology are very good;

Patents: The number of patents can well show the manufacturer's investment in equipment research and development and the professionalism of the equipment;

Plate and frame filter press.

Abstract:Diaphragm filter press is a filter press with a layer of elastic membrane between the filter plate and the filter cloth, which is similar to the basic principle and structure of the ordinary plate and frame filter press, the main difference is that the structure of the filter plate is different, which brings about different filter cavity formation and filter cloth style. Compared with the plate and frame filter press, the diaphragm of the diaphragm filter press can reduce the moisture content of the filter cake by 10-40%, save the follow-up cost, and the effect is better.

Let's take a look at the differences between diaphragm filter press and plate and frame filter press. 1. Introduction to diaphragm filter press.

Diaphragm filter press, also known as diaphragm filter press, is a filter press with a layer of elastic membrane installed between the filter plate and the filter cloth, which has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability, etc., and is a common equipment in metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical and other industries, and is widely used in various fields that require solid-liquid separation.

2. What are the differences between the diaphragm filter press and the Tuanliang plate frame filter press?

The basic principle and structure of the plate and frame filter press and the diaphragm filter press are the same, the difference is that the filter plate used in the diaphragm filter press is double-sided with a diaphragm cavity, and the specific differences between these two types of filter presses are:

1. The structure of the filter plate is different.

The filter chamber of the plate-and-frame filter press is composed of two kinds of filter plates staggered, one solid filter plate and one frame filter plate. The diaphragm filter press uses two different filter plates, one solid filter plate and one hollow filter plate. The frame filter plate is like four strips enclosed, and the hollow filter plate is cast together in two layers to form a large gap in the middle of the filter plate, which is the hollow filter plate.

2. The formation of the filter cavity is different.

The filter chamber of the plate-and-frame filter press needs two solid filter plates and a frame filter plate, and the diaphragm filter press is composed of a solid filter plate and a hollow filter plate.

3. Different styles of filter cloths.

The diaphragm filter press uses two filter cloths, which are connected in the middle to form a filter cloth monomer. The plate-and-frame filter press filter cloth is a square filter cloth. The filter cloth of the diaphragm filter press adopts the wrapping method, and one of the two layers is flattened after passing through the small hole in the middle of the filter plate to wrap the filter plate.

The plate-and-frame filter press can be placed directly between the filter plates.

3. Which is better, plate and frame filter press or diaphragm filter press?

Diaphragm filter press collapse and width machine.

The filter plate used in the diaphragm filter press is double-sided with a diaphragm cavity, and compared to the filter plate of the frame filter press, the diaphragm filter plate has two filter surfaces that can be moved back and forth: the diaphragm. When a press medium (e.g. compressed air) is introduced behind the diaphragm, these movable diaphragms bulge out in the direction of the filter chamber, i.e. the cake is pressed again at a high pressure after the filtration process.

The moisture content of the filter cake can be 10-40% lower than that of the filter plate of the ordinary plate and frame filter press, which can save a lot of follow-up costs.

Plate-and-frame filter presses need to be equipped with a compressed air pump instead of a regular air pump. The following are the basic steps for a plate-and-frame filter press with an air pump:

Determine the required air pump model and air pressure. According to the specifications of the plate-and-frame filter press and the well-known production process, select the appropriate air pump model and the appropriate air pressure.

Installation and commissioning of the air pump. Install the air pump in the appropriate location near the plate and frame filter press and wire and debug it according to the guidance in the air pump manual.

Regulate air pressure. Adjust the pressure of the air pump as needed to ensure that the plate and frame filter press is operating within the pressure range.

Conduct experiments and tests. After the installation and commissioning are completed, experiments and tests are carried out to ensure the normal operation of the plate and frame filter press and air pump, and to check whether other related equipment is well matched.

It should be noted that when installing and using the plate and frame filter press with air pump, it should be operated in strict accordance with the operation manual and installation instructions provided by the manufacturer to ensure the stability and safety of the equipment operation.

The air pressure plate and frame filter press and the plunger plate and frame filter press are two commonly used filter press equipment, each with its own advantages and disadvantages. Here's a comparison of the two:

1.Working principle: The air pressure plate and frame filter press uses compressed air to press the filter media, while the plunger plate and frame filter press is filtered by the hydraulic working principle.

2.Filtration effect: The air pressure plate frame filter press can obtain higher filtration efficiency and better filtration effect quietly, and has great advantages in solid-liquid separation. The filtration effect of the plunger plate frame filter press is also good, but relatively low.

3.Difficulty of operation: The operation of the air pressure plate frame filter press is relatively simple, and only the pressure, time, process parameters, etc. need to be set. The operation of the plunger plate and frame filter press is slightly more complex and requires the control of the hydraulic system.

4.Maintenance cost: The maintenance cost of the air pressure plate frame filter press is relatively low, and it is easy to clean and maintain; Piston plate and frame filter presses require a hydraulic system and are relatively expensive to maintain.

To sum up, these two types of filter press equipment have their own applicability in different occasions. If efficient solid-liquid separation and filtration with a high degree of fine residue are required, it is recommended to choose an air pressure plate frame filter press. If it needs to be used for the filtration of more viscous materials, and the requirements for the filtration effect are not particularly high, it is recommended to choose a plunger plate and frame filter press.

With the increasing demand for sand and gravel aggregates in the market, there are more and more domestic sand washing sludge dewatering equipment and sand making equipment manufacturers, but there are not many manufacturers who can undertake a complete set of sand washing sludge dewatering production line manufacturers, and most of them can only produce and manufacture a single equipment configured with sand washing sludge dewatering production line, such as sand washing machine, belt filter press, belt filter press, etc., and cannot provide a complete set of sand washing sludge dewatering production line solutions.

1. Program-controlled automatic high-pressure diaphragm press filter press

The high-pressure diaphragm press filter press is especially suitable for the chemical, pharmaceutical, mining and other industries, where a very low moisture content of the mud cake is required, and deep dewatering can be realized.

After high-pressure dewatering treatment, the moisture content of the filter cake can be reduced to meet the standards of landfill and incineration (the moisture content varies in different industries), and the weight and volume of the filter cake can be reduced by half compared with traditional dewatering equipment. The whole machine can realize fully automatic operation, equipped with filter cloth ** flushing system and electronic control valve instrument, which can be unattended.

2. Automatic carcose automatic cleaning filter press

Due to the large viscosity of some materials, it is difficult for the filter cake to peel off automatically, and the filter cloth varicose system can enable the filter press to change the inclination angle of the filter cloth when it is working, forming an inverted V-shape, and at the same time, the spring held on the filter cloth shakes due to expansion and contraction, so that the filter cake automatically falls off. The flexion rod is made of reinforced polypropylene, which is light in weight, corrosion-resistant, flexible and reliable in action, easy to hold and maintain.

3. The filter cloth automatically cleans the filter press

The water flushing filter press is based on the conventional filter press with an automatic high-pressure flushing device, which is mainly used for automatic cleaning of the filter cloth wrapped on the filter plate of the filter press. When the filter cloth has clogging symptoms, the filter cloth is automatically cleaned and smoothed with high-pressure water. In this way, the reed can restore the filtration speed of the filter cloth and prolong the service life of the filter cloth.

4. Hydraulic automatic pressure filter press

The automatic pressure holding filter press adopts an electric contact pressure gauge to achieve automatic pressure holding, which is convenient to operate, stable in operation and reliable in structure, and is suitable for filter presses with medium filtration area. Because it is a manual pull plate, it is suitable for filter presses with low working frequency and small number of filter plates.

5. Circular filter plate filter press

The round filter plate is used for solid-liquid separation in stone wastewater, ceramics, aged soil, building materials and other industries, with high filtration pressure and low moisture content of filter cake.
