The working principle of mechanical grid, the introduction of the grid machine

A rotary mechanical grille is a type of grille that can be continuously and automatically cleared. It consists of a number of identical rake tooth parts staggered and parallel assembled into a group of closed rake tooth chains, driven by the motor and reducer, through a group of sheaves and chains to form a continuous top-down circular movement, to achieve the purpose of continuously clearing the grid. When the rake tooth chain runs to the upper part of the equipment and the back, due to the guiding effect of the sprocket and the bent rail, the parallel rake tooth row can be dislocated, so that the solid dirt falls into the slag tank by its own weight, and when it falls off uncleanly, this kind of grid is easy to bring the dirt to the channel behind the grid.

When the steel wire rope traction drum mechanical grid is working, the steel rope driving device releases the rope, and the rake bucket goes down along the guide rail from the highest position (the end of the previous cycle of skimming), and the skimmer plate descends with the rake bucket under the action of its own weight. When the skimmer plate is reset, the rake bucket is opened and continues to go down until it reaches the lower limit of the channel under the promotion of the opening and closing rake device (electric push rod) under the promotion of the opening and closing rake device (electric push rod), after the rake tooth is inserted into the grid gap, the steel rope driving device retracts the rope, and the rake bucket and the bucket car go up along the guide rail after the rake bucket is completely closed, and the slag screening is removed until it touches the skimmer plate, under the action of the relative movement of the two, the screening slag is skimmed out, and the slag guide plate falls into the slag groove, and a working cycle is completed.

Hank environmental protection grille machine.

Grid machine is a kind of solid-liquid separation equipment that can continuously remove debris in the fluid, and is an indispensable special equipment in the production process of urban sewage treatment, water plant, power plant inlet, textile, food processing, papermaking, leather and other industries, and is the solid-liquid screening equipment commonly used in China.

Product introduction, working principle, scope of application, and product characteristics of the grid machine.

The rotary mechanical grid can effectively separate solid substances, effectively reduce suspended solids (SS) and chemical oxygen consumption (COD) in water, and reduce the treatment load of subsequent processes. At the same time, it is also used in industrial production for solid-liquid separation and useful substances.

Rotary grid is a kind of sewage treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid, which can be widely used in urban sewage treatment, tap water industry, power plant water inlet, and can also be used as a pre-screening equipment in the wastewater treatment process of textile, food processing, papermaking, leather and other industries, which is one of the most advanced solid-liquid screening equipment in China, filling the domestic gap.

The biggest advantage of the rotary mechanical grid is high degree of automation, high separation efficiency, low power consumption, no noise, good corrosion resistance, it can ensure continuous and stable work in the case of unattended, and the overload safety protection device is set up, and when the equipment fails, it will automatically shut down, which can avoid the overload of the equipment.

The equipment can arbitrarily adjust the equipment operation interval according to the user's needs to achieve periodic operation; It can be automatically controlled according to the liquid level difference before and after the grille; And there is a manual control function to facilitate maintenance. Users can choose according to different work needs. Due to the reasonable structural design of the equipment, when the equipment is working, it has a strong self-cleaning ability and will not be blocked, so the daily maintenance workload is very small.

1. It is used in the treatment of industrial wastewater such as papermaking, slaughtering, leather, sugar, winemaking, food processing, textile, printing and dyeing, petrochemical, etc., to remove solid substances such as suspended solids, floating solids, and sediments;

2. It is used for useful substances such as fibers and residues in papermaking, alcohol, starch, food processing and other industries;

3. It is used to replace the primary sedimentation tank in urban sewage treatment.

Advantages of grid structure:

Simple structure, easy to convert data; Overlay analysis and analysis.

Geographical phenomenon. It's easier to simulate; It is conducive to the application and analysis of remote sensing data; The output speed is fast;

Disadvantages of lattice structure:

It is difficult to express the topology; Large amount of graph data and data structure.

not tight and compact; Difficulty in projection conversion; The graphics quality is low, and the graphics output is not beautiful;

First of all, the application purpose can be achieved through equipment in the water plant, in the water plant, people have high requirements for water quality, so it is necessary to treat the sewage through professional equipment, and the installation and application of the grid grid can make the sewage treatment effect better, and can also avoid the disadvantages of the traditional process method, so the application of mechanical grid in the water plant is more common. In addition, the mechanical grid can also be installed and used at the cold water inlet of the power plant to achieve the application purpose, and this equipment can also provide convenient conditions for the development of related work in the process of operation. In the production and processing site, the grid equipment can also be used to treat the sewage, the installation and use of the grid equipment can effectively deal with the impurities generated in the production process, and the grid equipment can be installed and used in the city and the community to achieve the application purpose, and in the printing and dyeing line

The main process parameters of the grille are as follows:

1. The main process parameters of the grid are grid spacing, grid flow rate and head loss. Grid spacing is the distance between two adjacent grids, the grid spacing is greater than 40mm for the coarse grid, the grid spacing is between 20 and 40mm for the middle grid, and the grid spacing is less than 20mm for the fine grid.

2. The flow rate of the grid refers to the speed at which the sewage flows through the grid and the grid channel. The flow velocity of the gate should not be too large, otherwise it may rush over the soft debris that should be intercepted, and the flow rate of the gate is too small, and the sand particles with larger particle size in the sewage may be deposited in the channel in front of the gate.

3. The head loss of sewage through the grid refers to the water level difference before and after the grid, which is related to the flow rate of the grid. If the head loss of the grid increases, it means that the flow velocity of the gate increases, and it is possible that the amount of water passing through the grid increases, and it is more likely that the grid is partially blocked and needs to be cleaned in time. The decrease in the loss of the head of the gate indicates that the flow velocity of the gate is reduced, and it is necessary to take measures to prevent sand accumulation in the channel in front of the gate.
