Description

Technical Field

[0001] This utility model belongs to the technical field of dust collector bag cages, specifically relating to a brush-type dust collector bag cage. Background Technology

[0002] Dust collector cages are an important component of baghouse dust collectors. During installation, the cages are placed inside the dust collector filter bags, mainly to support and fix the filter bags, so that the filter bags can maintain the correct position and shape when filtering dust-laden gas.

[0003] In simple terms, dust-laden gas entering the dust collector passes through the filter bags inside the dust collector. The dust is intercepted by the filter bags and adheres to the outer surface of the filter bags, while the purified gas passes through the inside of the filter bags and is discharged from the dust collector outlet. In addition, sometimes fine dust particles may penetrate the fiber structure of the filter bags and enter the inner surface of the filter bags. Once the dust on the surface of the filter bags gradually accumulates, it will cause the air permeability of the filter bags to decrease and increase the resistance of the system.

[0004] When cleaning the filter bags, workers first need to unfasten the filter bags from the bag cage and then remove them. They then use tools to remove the dust from the filter bags. After cleaning, the filter bags are reinstalled on the bag cage. The whole process is quite cumbersome, increases the workload of workers, and is not conducive to equipment maintenance. Therefore, a brush-type dust collector bag cage is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a brush-type dust collector bag cage to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a brush-type dust collector bag cage, comprising: a bag cage body, the bag cage body including a top cover, a base, cage ribs and a fixing ring, wherein multiple cage ribs are provided, the multiple cage ribs are spaced apart, the cage ribs are connected to the top cover and the base, the fixing ring is installed on the lower surface of the top cover, and the cross-sectional diameter of the fixing ring is smaller than the cross-sectional diameter of the top cover, the top cover and the fixing ring form an installation cavity;

[0007] The first cleaning assembly includes a movable disc, a cleaning brush, a fixed cylinder, a movable rod, and a limiting rod. The cleaning brush is evenly distributed on the circumferential side of the movable disc. The movable rod is movably inserted into the fixed cylinder along its own axial direction. The limiting rod is horizontally installed at the lower end of the movable rod. The lower end of the fixed cylinder is fixedly installed on the base. There are two limiting rods, which are perpendicular to each other. The fixed cylinder has a sliding groove that matches the limiting rod.

[0008] A second cleaning component is installed in the mounting cavity.

[0009] As a preferred embodiment, the second cleaning component includes jet pipes and an air intake ring. Multiple jet pipes are provided, and the multiple jet pipes are installed at intervals on the air intake ring and communicate with the air intake ring. The air intake ring is installed in the mounting cavity.

[0010] As a preferred embodiment, the second cleaning assembly further includes a support column and a limiting plate. The top cover has a movable hole for the support column to move. The limiting plate is installed at the upper end of the support column, and the lower end of the support column is installed at the air intake ring. The cross-sectional diameter of the limiting plate is larger than the diameter of the movable hole.

[0011] As a preferred embodiment, the second cleaning assembly further includes a wedge block and a return spring. The support column has two opposing mounting slots, and multiple pairs of wedge blocks are provided. One pair of wedge blocks is slidably placed in the mounting slot, and the return spring is connected to the inner wall of the wedge block and the mounting slot.

[0012] As a preferred embodiment, the end of the movable disk away from the movable rod has a limiting groove, which is adapted to the limiting rod.

[0013] As a preferred embodiment, the movable rod has a handle at the end away from the movable disk, and the cross-sectional diameter of the handle is larger than the cross-sectional diameter of the fixed cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features a first cleaning component, which includes a movable disc, a cleaning brush, a fixed cylinder, a movable rod, and a limiting rod. The cleaning brush is mounted on the movable disc, the movable rod is inserted into the fixed cylinder, and the limiting rod is horizontally installed at the lower end of the movable rod. The fixed cylinder is fixedly installed on a base and has a sliding groove. When the inner surface of the filter bag needs to be cleaned, the user pulls the movable rod up and down using the handle. Since the limiting rod engages with the limiting groove, it causes the movable disc and the cleaning brush mounted on the movable disc to move up and down together. In this way, the dust on the inner surface of the filter bag is cleaned by the up-and-down moving cleaning brush, eliminating the need for the user to remove the filter bag from the bag cage body, thus facilitating daily maintenance.

[0016] This invention features a second cleaning assembly comprising a jet pipe, an air inlet ring, a support column, a limiting plate, a wedge block, and a return spring. The jet pipe is installed on and connected to the air inlet ring, which is installed in the mounting cavity. The top cover has a movable hole, the limiting plate is installed on the support column, and the support column is installed on the air inlet ring. The support column has a mounting groove, and the wedge block is slidably placed in the mounting groove. The return spring is connected to the inner wall of the wedge block and the mounting groove. When cleaning the outer surface of the filter bag, the user first connects the air inlet ring to the compressed air device via a pipe. Then, the user squeezes the wedge blocks in the two opposing mounting grooves, compressing the return spring and reducing the distance between the pair of wedge blocks. This allows the support column to move downward through the movable hole, causing the limiting plate to fit against the upper surface of the top cover. The compressed air device is then activated, and a high-speed airflow blows downward through the jet pipe via the air inlet ring, thus blowing away the dust on the outer surface of the filter bag. This simple operation further improves the efficiency of cleaning filter bag dust. Attached Figure Description
