Description

Technical Field

[0001] The invention relates to the field of dust removal, in particular to a dust cleaning cover plate and a dust collector having the dust cleaning cover plate. Background Art

[0002] There are two main ways to clean dust collectors at present. One is the pulse jet dust collector, such as Figure 1 As shown. The other is a box-type back-blowing dust collector; the pulse row spray dust collector is to set up a spray pipe with an air nozzle above each row of bags. After the compressed air enters the spray pipe, it sprays out high-pressure air through the air nozzle, causing the bags to quickly inflate and shake to achieve the purpose of dust removal. The disadvantage of this spray method is that it is difficult and complicated to make. It is necessary to set up a spray pipe above each row of bags, which is cumbersome. At the same time, it is not convenient to replace the bags, because when replacing the bags, the upper cover needs to be opened and the spray pipe needs to be removed before the bags can be replaced, which is extremely inconvenient.

[0003] The box-type back-blowing dust collector has a large compressed air intake pipe installed in each closed dust collector clean air chamber. When dust cleaning is required, the compressed air enters the closed chamber through the intake pipe, the pressure in the chamber increases, and the bag quickly inflates and shakes to achieve the purpose of dust cleaning. The disadvantage of this dust cleaning method is that there is no air nozzle above each bag to drain the compressed air, and the dust cleaning effect is poor. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] The present invention provides a dust cleaning cover plate, comprising: a cover plate body, on which an air inlet pipe and an air outlet pipe are arranged, wherein the number of the air outlet pipes is multiple, and the air outlet pipes are all arranged on the bottom surface of the dust cleaning cover plate, and all the air outlet pipes are arranged downward, and all the air outlet pipes are connected to the air inlet pipe.

Therefore, when manufacturing the cover plate body, the air outlet pipe is pre-connected to the lower cover, and the air inlet pipe is pre-connected to the upper cover. When the upper cover and the lower cover are connected, a channel for connecting the air inlet pipe and the air outlet pipe can be formed, which simplifies the pipeline manufacturing and is easy to process and manufacture.

[0009] As some sub-solutions of the above technical solution, a first baffle is formed by bending downward along the outer edge of the upper cover, and a second baffle is formed by bending upward along the outer edge of the lower cover, the second baffle is located on a side of the lower cover close to the first baffle, and a slot is formed between the first baffle and the second baffle. When the upper cover and the lower cover are connected, the first baffle and the second baffle can form a slot, providing a method for easily realizing the manufacturing of the slot.

[0010] As some sub-solutions of the above technical solution, the outlet pipe is arranged in a rectangular shape. The outlet pipe arranged in a rectangular shape has a large outlet area, and when installed in the dust collector, it can output gas to the external bag and also to the surrounding environment of the bag.

[0011] As some sub-solutions of the above technical solution, a handle is further provided on the upper side of the cover body, so that the cover body can be easily lifted.

[0012] The present invention also provides a dust collector with a dust cleaning cover, comprising a dust collector body, a removal port is provided on the upper side of the dust collector body, and further comprising the dust cleaning cover described in any of the above technical solutions, the dust cleaning cover is connected to the dust collector body and closes the removal port.
