Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a pulse dust collector with a filter screen that is easy to disassemble. Background Art

[0002] Pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber backblowing, overcomes the shortcomings of insufficient chamber cleaning intensity and uneven distribution of inlet and outlet air, and expands the scope of application. When the dust-laden gas enters the dust collector from the air inlet, it first hits the inclined plate and baffle in the middle of the inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down. Due to the effect of inertia, the coarse dust particles in the gas flow directly into the ash hopper, which plays the role of pre-dust collection. The airflow entering the ash hopper then turns upward and passes through the filter bag with a metal skeleton inside. The dust is captured on the outer surface of the filter bag. The purified gas enters the cleaning chamber above the filter bag chamber and is collected at the air outlet for discharge. In the process of dust-laden gas passing through the filter bag for purification, the dust accumulated on the filter bag increases with time. As more and more dust is added, the resistance of the filter bags is increased, resulting in a gradual decrease in the processing air volume. For normal operation, the resistance must be controlled within a certain range (140-170 mm water column). Once the range is exceeded, the filter bags must be cleaned. During cleaning, the pulse controller sequentially triggers each control valve to open the pulse valve, and the compressed air in the air bag is sprayed from the holes of the injection pipe through the venturi tube into the corresponding filter bags. The filter bags expand rapidly in an instant, causing the dust accumulated on the surface of the filter bags to fall off, and the filter bags return to their initial state. The cleaned dust falls into the ash hopper and is discharged from the body through the ash discharge system. As a result, the dust accumulated on the filter bags is periodically pulse-blasted for cleaning, allowing the purified gas to pass normally and ensuring the operation of the dust removal system. When the existing pulse dust collector needs to replace the filter screen, it is very troublesome to disassemble the filter screen, resulting in a long time for disassembly of the filter screen and a decrease in the work efficiency of workers.

[0003] In order to solve the above-mentioned problems, a search found that the utility model patent with the authorization announcement number CN 215027023 U discloses a pulse dust collector that is easy to remove the filter, including a pulse dust collector body, the left side of the pulse dust collector body is connected to the air intake pipe, and the right side of the pulse dust collector body is connected to the exhaust pipe. The solution is to set a slide groove and a slide plate to cooperate with each other to slide and limit the filter, thereby improving the stability of the filter during use and preventing the filter from shifting. At the same time, it is easy to install and remove the filter, saving the time of installation or removal of the staff and improving work efficiency. By setting a positioning groove to limit the card rod, the stability of the card rod is improved. By setting a card rod and a card groove to cooperate with each other to limit the slide plate, the stability of the slide plate is improved. At the same time, it solves the problem that when the existing pulse dust collector needs to replace the filter, it is very troublesome to remove the filter, resulting in a long time to remove the filter and a decrease in the work efficiency of workers.
