Pneumatic conveying equipment has good dust-proof effect; it is easy to realize mechanization and automation, can reduce labor intensity and save manpower; in the conveying process, it can carry out a variety of process operations at the same time, such as mixing, crushing, sorting, drying and cooling.
Working principle of pneumatic conveying equipment: pneumatic conveying equipment is composed of diffusion chamber, mixing chamber, movable air duct and actuator. The low pressure air enters the diffusion chamber through the air inlet pipe, the mixing chamber and the diffusion chamber. The high-speed airflow vaporizes the materials around the nozzle through the mixing chamber, and the air flow from the nozzle into the diffusion chamber forms a local negative pressure between the nozzle and the diffusion chamber, and the vaporized material is sucked into the conveying pipe and lifted to the unloading point by the high-speed airflow.
Application of pneumatic conveying equipment: pneumatic conveying equipment is the preferred conveying equipment in power plant, cement plant and chemical plant. Its advantages such as simple structure, large conveying capacity, no occupation of space and so on, help many enterprises to complete the transportation work with high quality, and effectively solve the shortcomings of the above-mentioned enterprises such as large pollution and large equipment investment. It is also used in casting, metallurgy, chemical industry, building materials, grain processing and other departments.
Rotary valve (also known as star feeder and impeller feeder) is a uniform and continuous batch processing, conveying and discharging device in mechanized automation control system. It has the advantages of compact structure, light weight and strong operation ability. Rotary valve is used in air transportation engineering and bulk material processing system in powder engineering, grain processing, port and wharf, petrochemical, chemical fiber, chemical industry, electric power, medicine, food, building materials, mining and other industries. Automatic distance control is widely used.
