Pulse dust collector

Abstract

The invention aims to provide an air filter screen of a pulse dust collector, which is characterized in that a blowpipe (7), electromagnetic valves (8) and an air bag (9) are arranged below a pulse partition plate (6), and the working time of the two groups of electromagnetic valves can be adjusted. In the working process, although materials on the surface of the cloth bag (11) cannot completely fall off under the condition of transient pulse back blowing, due to the fact that the air blowing pipe (7), the electromagnetic valves (8) and the air bag (9) are additionally arranged, under the control of a time electric appliance, dust on the outer surface layer of the cloth bag (11) can be cleaned through the air blowing pipe (7), and the working time of the two sets of electromagnetic valves can be adjusted.

Description

Technical Field

[0001] The invention relates to a pulse dust collector, which is usually used in the industries of textile, papermaking, feed, grain, food, chemical industry, medical treatment and the like. Background Art

[0002] The pulse dust collector mainly comprises an air inlet (1), a pulse box (2), an air bag (3), a solenoid valve (4), an air blowing pipe (5), the air blowing pipe (5) having a hole corresponding to the inside of a cloth bag (11), a pulse partition (6), an air outlet (10), a cloth bag (11), a lower hopper (12), and a discharge air shut-off device (13).

[0003] The working principle is that dust-containing air enters from the air inlet (1), is filtered by the bag (11), and then the clean air goes out from the air outlet (10). The dust is isolated by the bag (11) and adsorbed on the bag (11). The air bag (3) is filled with compressed air. Under the control of the timer, the solenoid valve (4) is opened, and pulse air passes through the blowing pipe (5). The blowing pipe (5) has holes corresponding to the inside of the bag (11) and can be blown into the corresponding bag (11). After the bag (11) is back-blown, it vibrates, and the dust adsorbed on the outer layer of the bag (11) falls off, settles to the bottom through the lower hopper (12), and is discharged by the discharge air shutoff device (13).

[0004] In actual operation, the material on the outer layer of the bag (11) does not completely fall off in the case of transient pulse backblowing. When the pulse air disappears, the dust on the outer layer of the bag (11) is immediately adsorbed. Therefore, after working for a period of time, the dust on the outer layer of the bag (11) gradually accumulates, the wind resistance becomes larger, and the suction effect is affected, especially in the auxiliary suction process of the crusher, which seriously affects the normal operation of the crusher.

[0005] For a long time, this problem has been taken for granted, is widespread and has never been solved. Summary of the invention

[0006] The object of the present invention is to provide a pulse dust collector, which requires that after working for a period of time, the surface dust will not gradually accumulate and the wind resistance will not increase.

[0007] The scheme of the present invention is as follows: a pulse dust collector mainly comprises an air inlet (1), a pulse housing (2), an air bag (3), a solenoid valve (4), a blowing pipe (5), the blowing pipe (5) having a hole corresponding to the inside of a cloth bag (11), a pulse baffle (6), an air outlet (10), a cloth bag (11), a lower scoop (12), and a discharge air shut-off device (13). The feature of the invention is that: below the pulse baffle (6), there is also a blowing pipe (7), the blowing pipe (7) having a hole corresponding to the outer layer of the cloth bag (11), a solenoid valve (8), an air bag (9), and the working time of the two sets of solenoid valves can be adjusted. During operation, although the material on the surface of the bag (11) will not completely fall off in the case of transient pulse backblowing, due to the addition of the blowing pipe (7), the blowing pipe (7) has holes corresponding to the outer layer of the bag (11), the electromagnetic valve (8), and the air bag (9), under the control of the time electrical appliance, the dust on the outer layer of the bag (11) can be cleaned through the blowing pipe (7), and the working time of the two sets of electromagnetic valves can be adjusted, thereby avoiding the problem of dust slowly accumulating and the wind resistance will not become larger, thereby achieving the purpose of the present invention.
