Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, and particularly relates to a filtering structure for environmental protection equipment which is convenient for disassembly and assembly. Background Art

[0002] Environmental protection equipment refers to mechanical products, structures and systems manufactured and built by production units or construction and installation units for controlling environmental pollution and improving environmental quality;

[0003] A bag filter is a common industrial dust removal equipment. It filters industrial waste gas through filter bags, intercepts dust and particulate matter on the filter bags, and makes the waste gas emission meet the environmental protection requirements. However, with the increase of service time, the filter bags will gradually accumulate dust, resulting in a decrease in dust removal efficiency and even air leakage. Therefore, regularly replacing the filter bags is an important measure to ensure the normal operation of the bag filter;

[0004] It is found in actual use that the following deficiencies exist when replacing the filter bags of the existing bag filter:

[0005] When disassembling the dust removal filter bag, since the dust removal filter bag is vertically arranged inside the dust collector, and there is a lot of dust inside the dust collector due to ash removal, after closing the intake valve and discharging the gas inside the filter bag completely, it is necessary to reach in from the side to remove the filter bag. However, the position of the dust removal filter bag is fixed inside the dust collector, resulting in a relatively narrow field of vision during disassembly and assembly operations, making disassembly and assembly inconvenient;

[0006] When disassembling the dust removal filter bag, since the dust removal filter bag is fixed to the connecting seat of the dust collector through a skeleton, when using tools to disassemble the fastening screws on the dust removal filter bag and the skeleton, since the dust removal filter bag is sleeved on the outer end of the skeleton, it is easy to pull or tear the dust removal filter bag, which will cause damage to the dust removal filter bag;

[0007] Therefore, the present application provides a filtering structure for environmental protection equipment which is convenient for disassembly and assembly to meet the requirements. Content of the Utility Model

[0008] The purpose of the utility model is to solve the problems existing in the above background art, and to propose a filtering structure for environmental protection equipment which is convenient for disassembly and assembly.

[0009] To solve the above technical problems, the utility model provides the following technical solutions:

[0010] A filter structure for an environmental protection device that is convenient for disassembly and assembly, comprising: a filter cartridge, a cover plate, a track, an electric telescopic rod, a cross bar, a fixed seat, a connecting frame, a docking piece, a dust removal filter bag, a skeleton and a protective sleeve. The cover plate is installed at the top of the filter cartridge. A track is installed at the upper end inside the filter cartridge. An electric telescopic rod is installed inside the track. The output end of the electric telescopic rod is installed with a cross bar. Several groups of fixed seats are installed at the outer end of the cross bar. The lower end of the fixed seat is installed with a connecting frame. Docking holes are arranged on the surface of the connecting frame. A docking piece is installed at the port of the connecting frame. Mounting holes are arranged on the surface of the docking piece. A dust removal filter bag is installed inside the connecting frame. A skeleton is sleeved inside the dust removal filter bag. A protective sleeve is installed at the outer end of the dust removal filter bag.

[0011] Preferably, there are two groups of tracks, and the two groups of tracks are respectively located on the left and right sides at the upper end inside the filter cartridge.

[0012] Preferably, the track and the electric telescopic rod are both vertically arranged, and the cross bar is horizontally spanned between the two groups of tracks. The dust removal filter bag is located directly below the cover plate.

[0013] Preferably, the connecting frame is circular, and the connecting frame is fixed to the fixed seat by screwing bolts into the docking holes.

[0014] Preferably, the docking piece is rectangular, the docking piece extends longitudinally outward from the port of the connecting frame, and the mounting holes are located on the side surface of the docking piece.

[0015] Preferably, the protective sleeve is circular, and the protective sleeve is made of rubber material. The connecting frame is sleeved at the outer end of the protective sleeve.

[0016] Preferably, both the connecting frame and the protective sleeve are sleeved at the upper end outside the skeleton, and the dust removal filter bag is located in the middle of the connecting frame, the protective sleeve and the skeleton.

[0017] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0018] 1. The electric telescopic rod can stretch up and down in the two groups of tracks to drive the cross bar to move up and down. Thus, when disassembling and assembling the dust removal filter bag, the operation can be carried out directly up and down, so that the dust removal filter bag and the fixed seat are directly and completely exposed at the upper opening of the filter cartridge. This not only facilitates finding the connection position of the dust removal filter bag, but also can quickly remove multiple groups of dust removal filter bags, making the disassembly and assembly more convenient;

[0019] 2. When the connecting frame is removed from the fixed seat, the entire connecting frame can be tightened or loosened by adjusting the bolts at the docking parts, so that the skeleton and the dust removal filter bag can fall off directly, making the disassembly more convenient. It is convenient to remove both the skeleton and the dust removal filter bag without removing the dust removal filter bag from the skeleton, which can avoid pulling or tearing the dust removal filter bag, thus avoiding damage to the dust removal filter bag during disassembly and assembly.
