Description

Technical Field

[0001] The utility model relates to the technical field of suction and discharge tank trucks, in particular to a dust removal device for suction and discharge tank trucks. Background Art

[0002] A suction and discharge tank truck is a vehicle used to transport fine powder materials. When in use, the air compressor is driven by a transmission device. The compressed air generated enters the air chamber through a control pipeline, causing the powder and granular materials in the tank to fluidize, completing loading and unloading. Existing suction and discharge tank trucks also inhale air when the tank truck inhales powdered materials, causing the pressure in the vehicle to increase. In order to relieve the pressure, another opening needs to be opened on the tank truck for pressure relief, but this will also cause dust materials to be sprayed out with the air, causing environmental pollution.

[0003] In the prior art, Chinese Patent Publication No. CN218280952U discloses a pressure relief and dust removal device for the ash conveying process of a suction and discharge tank truck, including a tank body mechanism, a pressure relief mechanism is fixedly provided at the middle position of one end of the upper surface of the tank body mechanism, a dust removal mechanism is fixedly provided at the center of the pressure relief mechanism, and a pipeline mechanism is fixedly provided at the bottom position of the front side edge of the tank body mechanism. In the utility model, the pressure relief port of the suction and discharge tank truck is enlarged, a box body connected to the space inside the tank is installed in the port, a perforated plate is installed at the enlarged pressure relief port, and a detachable dust bag cage and dust filter bag are installed on the perforated plate. During use, when pressure relief is required, the dust-containing gas in the tank enters the newly added dust collecting chamber, and after the gas is filtered by the dust filter bag, the clean air is discharged into the atmosphere, thereby solving the problem of dust-containing gas from the pressure relief tank truck polluting the environment during loading.

[0004] However, when the utility model is actually used, when the air containing dust is depressurized, the air is blocked by the dust filter bag. When there is a lot of dust, the mesh of the dust filter bag is small, which blocks the flow rate of air, slows down the air discharge speed, and affects the efficiency of pressure relief. Therefore, improvement is needed. Utility Model Content
