Learn powder conveying and calculate what books are appropriate to buy

The material particles are large, the shape is not standardized, and the material will be blocked in the nozzle and manually stirred from time to time. Altering the vacuum fan may not work. Because the negative pressure does not increase.

Daewoo Machinery low-pressure pneumatic conveying material seal pump is a special equipment developed by using the principle of pneumatic pressure difference and jet flow technology and fluidization technology to require continuous conveying mode in the powder pneumatic conveying process, the material enters the material seal pump from atmospheric pressure, and the material is sent into the conveying pipe by using the lone jetting device, and the material is sent to the destination along the pipeline by using the pneumatic pressure difference, with simple overall structure and reliable operation. Due to the continuous conveying, low pressure and large air volume, the flow rate in the pipe is low and constant, so the wear is small and the service life is long.

Selection principle. To select Daewoo low-pressure pneumatic conveying equipment material seal pump as the core equipment to form the pneumatic conveying system, first of all, the user should provide: the system requirements for conveying volume, conveying distance, or physical and chemical parameters of the material, maximum temperature and normal working temperature; If it is under the boiler dust collector, the basic parameters such as the arrangement of the dust hopper and the amount of ash distribution of the dust collector should be provided.

Then the technical staff of our factory first determines the basic transportation scheme, such as the required gas volume, how to group, continuous pump model, air inlet and conveying pipeline configuration, and warehouse top dust collector configuration, and finally the user reviews and determines.

Conditions apply. The material seal pump of low-pressure pneumatic conveying equipment is limited to a certain extent due to the use of low-pressure conveying, and can only be used normally and safely under the following conditions, and achieve the desired effect.

Conveying distance 500m (equivalent distance).

The specific gravity of the material is powder).

The maximum number of string pumps is not more than 4 (i.e. 4 sets with one ash pipe).

The maximum instantaneous temperature of the material is 250 °C.

I feel that the problem you said belongs to the more typical problem in pneumatic transportation, and the situation you said will occur when the diameter of the powder is very small, which can be said to be a short board in gas transportation, so the way you can think of is more far-fetched: 1. Clean the pipeline: you can use a special pipe brush, and everyone who does pneumatic transportation knows it, and use a small ball that can be recycled to do disturbance cleaning.

2. Filter element cleaning: It is recommended to use a back-blowing dust collector. Reasonable design for regular self-cleaning.

Third, the way of mechanical conveying can be considered. It depends on the project.

I know this point better, the pipe chain conveyor produced by our company is suitable for all kinds of powder materials, small granular materials, and its advantages are also particularly obvious, such as multi-point feeding and discharging, full closed transportation, flexible layout, etc., and viscous materials and high-temperature materials can also be transported, generally suitable for fine chemical industry, building materials industry, food industry, mining, pharmaceutical industry, etc. If you are interested, you can go to my homepage to see the articles introduced.

The low-pressure screw air compressor is better for split conveying, and the low-pressure powder conveying screw machine is suitable for concrete stations, mixing stations, bulk cement transfer warehouses, cement plants, pulverized ore plants, fly ash warehouses, tank ship unloading, steel plants, thermal power plants, food factories, and other powder conveying industries, and special external gas sources for environmental protection.

Advantages: low noise, no water, fast gas, high efficiency, continuous 24-hour operation, fully intelligent CNC electric cabinet, no need to add a gas tank refrigeration dryer. If you need to consult, Suzhou Shuoyong Electromechanical.

There are many powder conveying equipment in China, I don't know if you ask whether to do "conveying system" or "conveying equipment".

"There are many companies in China to choose from, but to give you a suggestion, when looking for equipment manufacturers, we must examine whether it is a "middleman", it is best to find its own factory, cheap and reliable;

"You can go to Shanghai Chixiang, the company's feed conveying system is designed by him, which is very good."

I feel that the problem you said belongs to a more typical problem in pneumatic transportation, and the situation you said will occur when the diameter of the powder is very small, which can be said to be a short board in gas delivery, so the way you can think of is also more far-fetched:

It's a little incomprehensible.

1. How is the starting point fed?

2. How is the end point unloaded?

3. Your filtration area has been calculated, it seems that the air volume has also been counted, and the negative pressure fan is about a kilogram, so you have to ask the fan manufacturer when choosing a fan.

To do negative pressure powder conveying system, you are equivalent to the design of powder conveying system.

You have to first formulate it according to your actual situation.

Their own related equipment also needs to be purchased, and they also need professionals to debug.

Guangdong Honggong suggests that it should be designed and installed by a professional powder conveying system company.

Because this is a set of system engineering, professional personnel are also required for later maintenance.

Designing your own and buying related equipment can be a lot of uncertainty, and you can't find the cause when something goes wrong.

Technical support also doesn't.

I Qing lead bend is to do industrial anti-corrosion, and I don't know this very well. However, the anti-corrosion of the open surface in the petroleum liquefaction pipeline can be made with epoxy asphalt paint 15130 from Hempel Paint, it is very famous that many oil liquefaction pipelines are specified in this way.
