Function of electric air lock in pneumatic conveying system

The function of electric air lock in pneumatic conveying system pneumatic conveying is a simple and effective way of conveying powder and granular materials in industry. The conveying system is usually composed of the following parts:

(1) Compressed air source, in most cases, the use of compressed air through the compressor;

(2) Feeding equipment;

(3) Transportation pipeline;

(4) The receiving silo is used to store the materials transported by the system. Usually, the system is a closed loop, and the pressure inside the system can be high pressure, low pressure, or negative pressure. For materials with special properties, different conveying forces are used. For example, for materials with strong hygroscopicity, dry gas is used for conveying; for materials with potential explosion risk, inert gas is used for conveying. Pneumatic conveying has been playing an irreplaceable role in medicine and food, chemical industry, metallurgy, new energy materials and other industries.

Electric air lock is also known as air closers, discharge valves, ash discharge valves, etc. Electric air lock is an important equipment in pneumatic conveying and ventilation and dust removal network. Its main function is to continuously and timely discharge the materials in the discharge or dust collector, and prevent the pressure in the device from being exposed to the normal pressure environment.

The electric air lock is an improved impeller open air closing device. Its structure is composed of impeller, shell, end cover, bearing, plexiglass tube (with or without) and material drawing mechanism. The upper end has a flange connected to the discharge port of the discharger. When the impeller rotates continuously, it receives the material discharged from the discharger and moves the material out from the bottom. Impeller adopts open type to prevent blockage, reduce machine weight and beautify appearance.
