Automatic pulse dust removal cleaning system and method based on pressure detection

Abstract

The invention discloses an automatic pulse dust removal cleaning system and method based on pressure detection. The system comprises a purifying air chamber and a filtering air chamber, the filteringair chamber is communicated with a garbage can, a filter cylinder is installed in the filtering air chamber, an air pocket and a pulse valve are connected in the purifying air chamber, the air pocketis communicated with the pulse valve, the bottom end of the pulse valve penetrates through the purifying air chamber and extends into the filter cylinder, and an air spraying hole is formed in the bottom end of the pulse valve; a differential pressure gauge is connected in the purifying air chamber and comprises a first measuring port and a second measuring port, the first measuring port is used for detecting the pressure of the purifying air chamber, the second measuring port is communicated with the filtering air chamber through an air pipe, and the second measuring port is used for detecting the pressure of the filtering air chamber; and the differential pressure gauge and the pulse valve are in communication connection with a control display device. The pressure difference between theinner side and the outer side of the filter cylinder is detected through the differential pressure gauge to achieve that the blockage condition of the filter cartridge is detected, and the trouble that the filter cylinder needs to be manually disassembled for cleaning after being blocked is reduced.

Description

technical field [0001] The invention relates to the technical field of sanitation vehicles, in particular to an automatic pulse dust removal and cleaning system and method based on pressure detection. Background technique [0002] Existing dry road sweeper is equipped with the filter cartridge of filtering in order to solve the working dust that anhydrous causes. However, during the working process, dust is often adsorbed on the filter cartridge, causing the blockage of the pneumatic conveying of the road sweeper, which affects the working effect. The solution is to increase a reverse air flow to blow the dust on the surface of the filter cartridge. [0003] The reverse air flow will reduce the suction effect, and it is impossible to reverse the blowing flow infinitely. The existing technology is to use the pulse dust removal technology. No matter what the effect is, the reverse blowing flow is performed at a fixed time interval. The inventor found that the existing pulse d...

AI Technical Summary

Problems solved by technology

The inventor found that the existing pulse dust removal has the following disadvantages: 1. The user cannot determine whether the poor effect of picking up garbage is caused by the clogging of the filter cartridge;

(According to existing experience, it is easiest to unclog the filter cartridge in the early stage of clogging trend) 3. The ability to clear the clogging cannot be automatically adjusted according to the clogging situation of the filter cartridge, which often leads to complete clogging of the filter cartridge, and the filter cartridge needs to be disassembled and cleaned manually. Time-consuming and labor-intensive, very troublesome
