Description

Pulse bag type dust collector
Technical Field
The utility model relates to a dust collecting equipment technical field specifically is pulse bag collector.
Background
With the development of modern industry, the pollution of dust to the environment is becoming more and more serious, and the control of the pollution of dust and the purification of human living environment become common knowledge of people in China. In order to maintain the clean requirement of the production environment, places polluted by dust must be cleaned at any time, at present, a pulse bag type dust collector adopted in the process of the dust collector can slowly adhere to the upper layer of dust layer by layer along with the dust collection, and the dust collection efficiency can be reduced after long-term accumulation, so that the surface of the filter bag can be cleaned by removing dust according to different use conditions, and the good dust collection effect can be recovered. Usually, a back-blowing device of a pulse bag type dust collector can directly blow air to the inner surface of a filter bag to realize the dust cleaning effect on the filter bag, but the inner surface of the filter bag is blown only by wind power, so that dust on the outer surface of the filter bag falls, the effect is not good, and a lot of dust is still attached to meshes of the filter bag, so that the dust removing capability of the dust collector is poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is providing pulse bag collector to only rely on the blowback device to realize the deashing effect to the filter bag among the solution prior art, can not be with the dust clean up of filter bag surface, and the problem that the dust remover dust removal ability that causes descends.
In order to achieve the above object, the basic scheme of the present invention is as follows:
pulse bag collector, including the dust removal box, fan and pulse recoil device, including filter chamber and air-purifying chamber in the dust removal box, filter chamber and air-purifying chamber are through the filter bag intercommunication that is equipped with, be located and be equipped with feed inlet and bin outlet on the dust removal box of filter chamber, be equipped with the pivot in the filter chamber, the pivot is rotated and is connected on the dust removal box, a plurality of cams of fixedly connected with in the pivot, be connected with first elastic component between filter bag and the dust removal box, be connected with the second elastic component between the adjacent filter bag, the cam can offset with first elastic component or second elastic component, the installation is used for strutting the skeleton of filter bag in the dust removal box, the filter bag internal diameter is.
The technical principle and the beneficial effects are as follows:
after the pulse bag type dust collector normally removes dust for a period of time, the dust removing capacity of the filter bag is reduced as more dust on the outer surface of the filter bag accumulates, and at the moment, the pulse backflushing device is started to spray gas into the filter bag, so that the dust on the outer surface of the filter bag is blown off, and the purpose of removing dust is achieved. At the in-process of this deashing, the manual work makes the pivot rotate, it rotates to drive the cam, the outline of cam is hit and is beaten on first rubber rope and second rubber rope, make first rubber rope and second rubber rope then drive the filter bag vibrations lightly, heavily then drive the filter bag swing, filter bag vibrations or swing in-process, shake off the dust that is difficult to on the filter bag to blow off by gas, compare in prior art, this scheme can shake off the dust that is difficult to clear away on the filter bag, make the deashing effect better, and then the dust removal effect of guaranteeing the dust remover does not change.
Further, a corresponding cam is arranged below each first elastic part or each second elastic part, the cams are disc-shaped, and contour lines of adjacent cams do not coincide on a projection along the axial direction of the rotating shaft.
The filter bag has the advantages that the outer contours of the adjacent cams are not overlapped, so that when one cam is abutted against the first elastic part (hits the first elastic part), the adjacent cam can not be abutted against the second elastic part, and the filter bag can swing to one side of the first elastic part; on the contrary, the filter bag swings to one side of the second elastic piece, the rotating shaft continuously rotates, and the cam intermittently abuts against the first elastic piece and the second elastic piece, so that the filter bag continuously swings left and right.
Further, the first elastic piece and the second elastic piece are both rubber ropes.
The rubber rope has the beneficial effects that the rubber rope has high wear resistance, so that the rubber rope is more suitable for being used in a dust remover.
Further, the rotating shaft is driven by a motor. The motor drives to make the rotation of the rotating shaft more convenient
Further, still be equipped with the filter screen in the filter chamber, be connected with the third elastic component between filter screen and the dust removal box, the cam can offset with the filter screen.
The pulse bag type dust collector has the beneficial effects that when the pulse bag type dust collector works normally, the meshes of the filter screen are larger, so that impurities with lighter weight and larger volume can be blocked, and the impurities are prevented from rising along with airflow to be attached to the outer surface of the filter bag, so that the dust collection effect is further influenced.
And in the process that the cam hits the first rubber rope and the second rubber rope, the cam also hits the filter screen constantly, and the filter screen shakes from top to bottom under the combined action of cam and spring, and then shakes off adnexed debris and dust on the filter screen, plays the deashing effect to the filter screen.
Further, the third elastic member is a spring.
The spring has the advantages of simple purchase and low cost.
Furthermore, the air purifying chamber is provided with an air outlet, and an activated carbon plate is arranged on the air outlet.
The dust removal device has the beneficial effects that the peculiar smell of the filtered air is removed by adopting the active carbon plate while the dust is removed.
Further, the feed inlet is connected with an air suction arm.
The dust collector has the beneficial effects that after the air suction arm is used, the air suction arm can be moved to absorb dust-containing gas at different positions near the dust collector under the condition that the dust collection box body is not moved relatively to the condition that the air suction arm is not arranged, the operation is simple, and the dust collection range is wide.
Furthermore, the bottom of the filter chamber is funnel-shaped, so that impurities in the dust-containing gas can fall down conveniently.
Furthermore, the bottom of the dust removal box body is provided with a caster wheel. The pulse bag type dust collector can be conveniently moved to other places for dust collection.
