Intelligent type turnover plate type dual-layer dust discharge valve

Abstract

The invention discloses an intelligent type turnover plate type dual-layer dust discharge valve which comprises an upper valve body, a lower valve body and a middle box body. An upper valve plate is installed in the upper valve body, one side of the upper valve plate is provided with a sealing plate, a first driving device is installed inside the upper valve body, the output end of the first driving device is connected with a valve plate driving main shaft, the bottom of the upper valve body is provided with the middle box body, the bottom of the middle box body is provided with a lower valvebody, a conveying channel is installed between the lower valve body and the middle box body, the upper valve plate and a lower valve plate are independently driven and controlled, system air leakage is reduced, the turnover type valve plates have no impact on a sealing base under a speed-adjustable driving device, the axial torsion of the driving shaft is greatly reduced, the service life is long,a driver can be in three modes of a speed-adjustable gear motor, an electro-hydraulic corner detector and a pneumatic executor, and the driving mode meets on-site working conditions.

Description

technical field [0001] The invention relates to the technical field of ash unloading valves, in particular to an intelligent flap-type double-layer ash unloading valve. Background technique [0002] The traditional knife-edge ash unloading valves, plug-in ash unloading valves, hemispherical ash unloading valves, and spherical ash unloading valves of various industrial and mining enterprises are all eroded and worn on the sealing surface, and the hemispherical soft seal seal is filled with material, and the seal and air leakage occur Phenomenon, short service life, the traditional ash unloading valve adopts a mechanical cycle discharge type, the actuator frequently starts, consumes a lot of energy, wastes a lot of useless work, the opening angle of the traditional ash unloading valve is small, the opening and closing time is short, and unloading The small amount of material cannot meet the amount of material falling at the upper end of the ash discharge valve, resulting in ma...

Problems solved by technology

[0002] The traditional knife-edge ash unloading valves, plug-in ash unloading valves, hemispherical ash unloading valves, and spherical ash unloading valves of various industrial and mining enterprises are all eroded and worn on the sealing surface, and the hemispherical soft seal seal is filled with material, and the seal and air leakage occur Phenomenon, short service life, the traditional ash unloading valve adopts a mechanical cycle discharge type, the actuator frequently starts, consumes a lot of energy, wastes a lot of useless work, the opening angle of the traditional ash unloading valve is small, the opening and closing time is short, and unloading The small amount of material cannot meet the amount of material falling at the upper end of the ash discharge valve, resulting in material accumulation, which must be handled manually

Cannot realize production line automation

[0003] The ash unloading valve mentioned in Chinese patent CN202369074U adopts the traditional cam type to open, and the counterweight ash unloading valve is driven by a geared motor to rotate a camshaft for a long time, and the cam drives the crank arm to open the valve plate. When the cam rotates to the other side of the crank arm When turning sideways, the valve plate is closed under the action of the counterweight, the seal is subjected to a large impact, the sealing surface of the valve plate is severely worn, the drive shaft of the valve plate is subjected to a large axial force, it is easy to break, the bearing is damaged quickly, and the shaft end seal leaks air. The service life of the equipment is short, the geared motor rotates for a long time, and the energy consumption is large
