Technical Field

[0001] This utility model relates to a filter bag, and more particularly to a high-efficiency, low-resistance industrial dust removal filter bag, belonging to the field of filter bag technology. Background Technology

[0002] With societal progress, people have increasingly higher requirements for the quality of inhaled air, and their environmental awareness has improved. They are also paying more and more attention to the treatment of industrial waste gas. Whether it is to purify inhaled air to improve its quality or to treat industrial waste gas to protect the environment, filter bags are often used to filter dust particles in the air.

[0003] In traditional filter bags, the installation method at the top opening often becomes a key factor restricting efficiency. The installation process is cumbersome and complicated, which not only leads to low installation and disassembly efficiency, seriously affecting the overall progress of filter bag replacement, but also makes it difficult to effectively guarantee the sealing of the filter bag opening. Insufficient sealing performance will directly lead to a significant decrease in filtration efficiency and may also cause a series of subsequent problems, such as dust leakage and environmental pollution. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency, low-resistance industrial dust collector filter bag to solve the problems mentioned in the background art, such as the cumbersome installation method of the traditional filter bag with the top opening, which affects the installation and dismantling efficiency, hinders the filter bag replacement progress, and has poor sealing performance, which easily leads to decreased filtration efficiency, dust leakage and environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency, low-resistance industrial dust collector filter bag, comprising a ring, a pressure ring above the ring, a filter bag body sandwiched between the ring and the pressure ring, a sealing ring fixedly provided at the bottom of the pressure ring, a round tube fixedly provided at the top of the pressure ring, insert plates fixedly provided on both sides of the round tube, support blocks fixedly provided on both sides of the ring, the support blocks and the insert plates being interlocked, an inclined block slidably provided at the bottom of the insert plate, an inclined groove slidably engaged with the inclined block inside the insert plate, a bracket fixedly provided on one side of the support block, and a moving component for moving the inclined block inside the bracket.

[0006] As a preferred technical solution of this utility model, limiting rods are fixedly provided on both sides of the bottom end of the pressure ring, and limiting holes that slide with the limiting rods are opened on the surface of the ring.

[0007] As a preferred embodiment of this utility model, a bag cage is provided inside the filter bag body, and a rubber ring is fixedly provided at the connection between the filter bag body and the ring.

[0008] As a preferred embodiment of this utility model, the movable component includes a threaded rod, which is threadedly connected to the bottom of the bracket. One end of the threaded rod is rotatably connected to one side of the inclined block via a bearing, and the other end of the threaded rod is fixedly provided with a knob.

[0009] As a preferred embodiment of the present invention, four evenly spaced guide rods are fixedly provided on one side of the inclined block, and one end of the guide rods passes through the bracket and extends to the outside of the bracket.

[0010] As a preferred embodiment of this utility model, a corrugated pipe is fixedly provided at the top end of the circular tube, and a mounting ring is fixedly provided at the top end of the corrugated pipe, and a plurality of evenly spaced mounting holes are provided on the surface of the mounting ring.

[0011] As a preferred embodiment of this utility model, the middle part of the support block is provided with a slot for guide plate engagement, and the size of the inclined slot is larger than the size of the inclined block.

[0012] Compared with related technologies, the high-efficiency, low-resistance industrial dust collector filter bag provided by this utility model has the following beneficial effects:

[0013] 1. The configured moving components can effectively drive the inclined block to slide smoothly in the inclined groove, thereby causing the vertical plate to move in the vertical direction. This movement further drives the pressure ring to gradually approach the circular ring. As the pressure ring moves in the vertical direction, it cooperates with the circular ring to achieve a firm pressing and fixation of the opening of the filter bag body. This simplifies the installation and disassembly process of the filter bag body, ensures the efficient replacement of the filter bag body, and thus improves the overall work progress.

[0014] 2. By installing a sealing ring at the pressure ring position, the tight compression between the pressure ring and the ring significantly enhances the sealing performance between the two, further optimizing the sealing effect of the filter bag body, ensuring that it can perform its filtration function normally, effectively preventing dust leakage, and thus avoiding environmental pollution and other problems.
