Description

Technical Field

[0001] This utility model relates to the technical field of baghouse flue gas dust collectors, specifically a baghouse flue gas dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the dust hopper. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. Chinese Patent No. CN202222405175.3 discloses a baghouse dust collector including a dust collection box. A dust baffle is fixedly installed on one side of the inner wall of the dust collection box. The dust collection box and the dust baffle... A sliding plate is fixedly installed on one side of the outer wall of the plate. A filter plate is movably embedded between the inner surfaces of two sliding plates. Multiple sets of first holes are opened on the top of the filter plate. The bottom of each set of first holes is fixedly connected to a threaded pipe. A filter bag body is rotatably connected between the outer surfaces of the multiple threaded pipes. A support plate is fixedly installed on one side of the outer wall of the dust collector. This invention aims to solve the problem in the above-mentioned bag filter dust collector where, due to the integrated design of the equipment, dust particles gradually fill the gaps on the filter bag after a long time. Due to the difficulty in disassembling the equipment itself, it is difficult for workers to clean and replace the filter bags inside. Therefore, a bag filter dust collector is proposed.

[0003] Based on the above, the inventors have discovered the following problems: The aforementioned patent allows the sealing plate to be disassembled, followed by the sliding removal of the internal filter plate, and the removal of the filter bag body by rotation. After cleaning the dust off the outer surface of the filter bag body, it can be reinstalled in the same way, enabling the reuse of the filter bag body. However, since several filter bags are installed on the filter plate, the overall weight of the filter plate is relatively heavy, making it difficult for workers to pull it out of the sliding plate. In addition, the filter bag body needs to be rotated multiple times to be disassembled, which is time-consuming and labor-intensive, reducing work efficiency.

[0004] Therefore, we made improvements and proposed a baghouse flue gas dust collector. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a baghouse-type flue gas dust collector, comprising a dust collection box, an air inlet on one side of the dust collection box, an air outlet on the top of the dust collection box, a support block installed on the upper end of one side of the dust collection box, a dust collection air manifold installed on the upper surface of the support block, several air jet pipes installed on the inner wall of one side of the dust collection box, one end of the air jet pipes penetrating one side of the dust collection box and connecting to the upper surface of the dust collection air manifold, a support frame installed on the upper end of the inner wall of the dust collection box, an installation groove provided on the periphery of the support frame, a pair of grooves provided at the bottom of the installation groove, several auxiliary rollers installed in the grooves, a filter plate, several connectors installed on the bottom surface of the filter plate, a push plate movably connected to the periphery of the connectors, a pair of locking pins installed on both sides of the connectors below the push plate, and a bag body, a pair of U-shaped slots provided on both sides of the upper end of the bag body, the U-shaped slots matching the size of the locking pins, and the top of one side of the U-shaped slots extending to the upper surface of the bag body.

[0007] As a preferred embodiment of this utility model, a sealed door is installed on the side of the dust removal box near the notch of the support frame.

[0008] As a preferred embodiment of this utility model, the bottom end face of the dust removal box is provided with a discharge port.

[0009] As a preferred embodiment of this utility model, a support base is installed on the lower periphery of the dust removal box, and several support legs are installed on the bottom surface of the support base.

[0010] As a preferred embodiment of this invention, the size of the filter plate matches the size of the mounting groove.

[0011] As a preferred embodiment of this utility model, a compression spring is installed on the upper end face of the push plate, and the top end of the compression spring is connected to the bottom end face of the filter plate.

[0012] As a preferred embodiment of this invention, each of the several jet pipes is equipped with an air blowing head above each connector.

[0013] As a preferred embodiment of this utility model, a controller is installed on one side of the dust removal box.

[0014] The beneficial effects of this utility model are:

[0015] By using the mounting slots, auxiliary rollers, locking pins, and U-shaped slots in combination, when dust on the filter bag is difficult to clean through the dust collection air bag, the operator opens the door and pulls the filter plate to one side. Because several auxiliary rollers are installed in a pair of grooves, the operator can use relatively little force to pull out the filter plate. Then, the bag body is pushed upwards, causing the locking pins to move to the bottom of the U-shaped slots. The bag body is then rotated to move the locking pins to one side of the U-shaped slots. The bag body is then moved downwards, causing the pair of locking pins to disengage from the pair of U-shaped slots. After the bag body is cleaned, the above steps are repeated to lock the locking pins in place. Then, under the force of the compression spring, the compression spring pushes the bag body downwards through the push plate, and the locking pins can be stably locked in the U-shaped slots. This enables the quick installation and removal of the filter bag, improving work efficiency. Attached Figure Description
