Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a pulse dust collector for machining. Background Art

[0002] During the mechanical production process, some dust often appears, and a supporting dust removal device is needed to remove the dust. The dust in the air is sucked into the dust removal equipment by inhalation, and after a series of treatments, relatively clean air can be discharged, effectively reducing the harm of dust to workers.

[0003] Many existing devices do not have a deceleration structure at the air inlet, resulting in too fast air inlet rate, reducing the subsequent contact time with multiple groups of filter bags, and causing the problem of low filtration efficiency. Therefore, we propose a pulse dust collector for machining to solve the above problems. Summary of the Utility Model

[0007] Preferably, the pulse dust removal structure includes a plurality of filter bags uniformly installed on the top of the connecting plate through bolts.

[0008] Preferably, a blowing pipe is inserted into the top end inside the box body, and a plurality of high-pressure gas nozzles are uniformly installed at the bottom end of the blowing pipe through screw holes.

[0009] Preferably, an electromagnetic pulse valve is inserted at one end of the blowing pipe.

[0011] Preferably, the air bag is installed on the box body through bolts.

[0012] Preferably, an exhaust port is welded to the top of the box body.

[0013] In the present utility model, a mechanical processing pulse dust collector is provided as follows:

[0014] 1. In the present utility model, a number of rotatable deceleration plates are arranged inside the box body and at the air inlet. By using a number of deceleration plates to block the air flow successively, the flow rate of the air flow is reduced, so as to promote the settlement of large-particle dust, effectively increasing the contact time with multiple groups of filter bags and improving the filtration efficiency.

[0015] 2. In the present utility model, a number of deceleration plates receive and convert the kinetic energy when the air flow enters, control the synchronous rotation of the rotating shaft, and then realize the synchronous rotation of the dust discharge spiral blades, so as to discharge the dust deposited inside the box body through the dust discharge port, avoiding subsequent cumbersome cleaning work.
