[0013] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0015] This embodiment provides a filtration system for an electrostatic dust removal device, which mainly consists of an installation component 1, a sealing component 3, a primary filter component 4, a fixing component 5, and a fine filter component 6. The components work together to achieve efficient filtration of dust-laden air.

[0016] In this embodiment, the mounting component 1 serves as the support and mounting base for the entire filtration system, and includes a filter box 101, a mounting horizontal plate 102, a mounting threaded rod 103, a mounting nut 104, a mounting connecting bracket 105, and mounting bolts 106.

[0017] The filter box 101, as the core container, is fixedly installed above the filter tube 2, providing installation space for other components. The mounting plates 102 are symmetrically distributed on both sides of the outer wall of the filter box 101, forming a transverse support structure.

[0018] A pair of threaded mounting rods 103 are vertically inserted into the mounting plate 102, with their lower ends connected to the mounting plate 102 and their upper ends extending to the outside of the filter box 101. A mounting nut 104 is threaded into the middle of the threaded mounting rod 103. Rotating the mounting nut 104 adjusts the relative position of the threaded mounting rods 103, thereby fixing the components on them. A mounting bracket 105 is fixedly mounted on the top of the threaded mounting rod 103, and its surface has multiple sets of mounting holes. A pair of mounting bolts 106 are inserted into the mounting holes of the mounting bracket 105 for connecting external equipment or fixing other components. Through this structure, the mounting assembly 1 not only provides stable support for the entire filtration system but also achieves flexible connection with other components through the adjustable threaded mounting rods 103 and mounting nuts 104, adapting to the needs of different installation scenarios.

[0019] In this embodiment, the main function of the sealing component 3 is to ensure the airtightness of the filter box 101 to the external environment and prevent the leakage of dusty air. It includes a sealing through hole 301, a sealing groove 302, a sealing ring plate 303, a sealing ring 304, and a sealing bolt 305. The sealing through hole 301 is symmetrically opened on the side wall of the filter box 101 for connecting pipelines or other components. The sealing groove 302 is opened around the edge of the side wall of the filter box 101 to form an annular sealing groove structure. The sealing ring plate 303 is symmetrically arranged on both sides of the side wall of the filter box 101, and its size matches the side wall of the filter box 101.

[0020] The sealing ring 304 is fixedly installed on the inner wall of the sealing ring plate 303. When the sealing ring plate 303 covers the side wall of the filter box 101, the sealing ring 304 is precisely inserted into the sealing groove 302, forming the first line of sealing defense. To further enhance the sealing effect, multiple sealing bolts 305 are evenly inserted on the sealing ring plate 303. After passing through the sealing ring plate 303, they are threaded to the side wall of the filter box 101. By tightening the sealing bolts 305, the sealing ring plate 303 is tightly fitted to the side wall of the filter box 101, while compressing the sealing ring 304 to ensure the reliability of the seal. This sealing assembly 3 effectively prevents the leakage of dusty air through the double sealing structure, ensuring the efficient operation of the filtration system.

[0021] In this embodiment, the pre-filter assembly 4 is responsible for the initial filtration of dust-laden air, removing larger dust particles. It includes a pre-filter mounting groove 401, a mounting baffle 402, an air pre-filter element 403, and a filter plate 404. The pre-filter mounting groove 401 is fixedly installed on the inner wall of the sealing ring plate 303, forming a space to accommodate the pre-filter components. The mounting baffle 402 is fixedly disposed on both sides of the inner wall of the pre-filter mounting groove 401, forming a guide structure to guide the flow direction of the dust-laden air. The air pre-filter element 403 is inserted in the middle of the pre-filter mounting groove 401 and has a porous structure to intercept larger dust particles while allowing air to pass through. The filter plate 404 is also inserted in the pre-filter mounting groove 401, located downstream of the air pre-filter element 403. Its surface has multiple sets of fine pores to further filter small particles in the air. Through this structure, the pre-filter assembly 4 achieves staged filtration of dust-laden air, reducing the burden on subsequent fine filter components and extending the service life of the entire filtration system.

[0022] In this embodiment, the fixing component 5 is used to fix the filter plate 404 in the primary filter component 4 to prevent it from shifting during use. It includes a fixing groove 501, a fixing horizontal plate 502, a fixing threaded rod 503, a fixing connecting rod 504, a fixing bushing 505, and a fixing nut 506. Two fixing grooves 501 are symmetrically formed on the outer wall of the primary filter mounting groove 401 to accommodate the fixing connecting rod 504. Two fixing horizontal plates 502 are symmetrically arranged on both sides of the outer wall of the primary filter mounting groove 401 to form a lateral support. The fixing threaded rod 503 is fixedly installed on the outer wall of the fixing horizontal plate 502, with its axial direction aligned with the length direction of the primary filter mounting groove 401. The fixing connecting rod 504 is inserted into the fixing groove 501. One end of the fixing assembly is fixedly connected to the outer wall of the filter plate 404, and the other end extends to the outside of the primary filter mounting groove 401. The fixing bushing 505 is fixedly installed on the end of the fixing connecting rod 504, and its inner hole size matches the fixing threaded rod 503. When the fixing connecting rod 504 is inserted into the fixing groove 501, the fixing bushing 505 is just fitted onto the fixing threaded rod 503. The fixing nut 506 is threaded to the top of the fixing threaded rod 503. By rotating the fixing nut 506, it presses the fixing bushing 505 downward, thereby fixing the position of the fixing connecting rod 504 and the filter plate 404. This fixing assembly 5 achieves reliable fixing of the filter plate 404 through a simple mechanical structure, and is easy to disassemble and replace.

[0023] In this embodiment, the fine filter assembly 6 is responsible for finely filtering the air after the initial filter to remove fine dust particles. It includes a sealing groove 601, a slider 602, a fine filter element 603, a fine filter sealing groove 604, a sealing plate 605, a sealing strip 606, and fixing bolts 607. The sealing groove 601 is symmetrically arranged on both sides of the inner wall of the filter box 101. Its cross-section is "T" shaped and is used to guide the sliding of the slider 602. The slider 602 is slidably arranged in the sealing groove 601. Its surface has multiple sets of mounting holes for connecting the fine filter element 603. The fine filter element 603 is installed between the two sliders 602. It uses high-efficiency filter material and can intercept fine dust particles. The fine filter sealing groove 604 is opened on the outer edge of the filter box 101 and corresponds to the position of the sealing groove 601. The sealing plate 605 is fixedly installed on the end of the slider 602 and its size matches the outer wall of the filter box 101. The sealing strip 606 is fixedly installed on the inner wall of the sealing plate 605; When the sealing plate 605 covers the outer wall of the filter box 101, the sealing strip 606 is precisely inserted into the fine filter sealing groove 604, forming a sealing structure. The fixing bolt 607 is inserted into the sealing plate 605, passing through it and threaded onto the outer wall of the filter box 101. Tightening the fixing bolt 607 ensures a tight fit between the sealing plate 605 and the outer wall of the filter box 101, while simultaneously compressing the sealing strip 606 to ensure reliable sealing. This fine filter assembly 6 features a sliding design for easy replacement and maintenance of the fine filter element 603, while the sealing structure prevents air leakage.
