Description

Technical Field

[0001] This utility model relates to the field of pressure relief and dust removal technology for suction and exhaust vehicles, and in particular to a pressure relief and dust removal device for suction and exhaust vehicles. Background Technology

[0002] A suction and discharge tank truck is a vehicle used for transporting fine powder materials. When in use, the air compressor is driven by the transmission device, and the compressed air generated enters the air chamber through the control pipeline, causing the powder material inside the tank to fluidize, thus completing the loading and unloading. Existing suction and discharge tank trucks also suck in air when the tank truck sucks in powder materials, which causes the pressure inside the vehicle to rise. In order to relieve the pressure, another opening needs to be opened on the tank truck, but this will also cause dust materials to be sprayed out with the air, causing environmental pollution.

[0003] Existing pressure relief devices can only collect dust through filter bags. However, since tank trucks are high up, personnel need to climb ladders to reach higher positions and use tools to disassemble and replace the filter bags and remove the dust inside. This results in low work efficiency and low safety. Therefore, we propose a pressure relief dust removal device for suction and exhaust trucks. Utility Model Content

The first lead screw, through a transmission gear, can also drive the second lead screw to rotate. The rotation of the second lead screw can then move the protective baffle to protect the exhaust nozzle. After the first lead screw rotates, a bevel gear can drive the third lead screw to rotate, allowing the third lead screw to move the dust discharge baffle downwards to seal the dust collection guide pipe. Opening the solenoid valve above the pressure relief pipe allows gas to escape from the exhaust port above. The dust filter screen can filter the dust. After the dust discharge baffle seals the dust collection guide pipe, it prevents gas from escaping from the dust collection guide pipe.

[0019] This utility model discloses a pressure relief and dust removal device for a suction and exhaust vehicle. Through the dust removal components of the suction and exhaust vehicle, after pressure relief, the solenoid valve is closed, and the motor rotates in the opposite direction. This allows the exhaust sealing baffle to seal the exhaust port and the protective baffle to remove its protective seal on the exhaust nozzle. The air pump is activated and supplies air to the exhaust nozzle through a pipeline. The exhaust nozzle can flush the dust filter in the opposite direction, preventing clogging. Dust is then discharged and collected along the dust collection guide pipe, which extends downwards from the main body of the vehicle. A guide ramp allows dust to be discharged towards the dust collection guide pipe, facilitating dust collection by personnel without requiring them to climb to higher positions to collect the dust.
