Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology, specifically relating to a self-cleaning filter cartridge dust collector. Background Technology

[0002] A cartridge dust collector is a device for filtering gas and dust. Dust-laden gas enters the dust collector under negative pressure. As the airflow passes through the filter cartridge, the dust is blocked by the cartridge and adsorbed on the outer surface of the cartridge. The filtered clean gas passes through the filter cartridge into the housing and is discharged by the fan.

[0003] Existing pulse jet dust collectors clean filter bags using a compressed air jet system. However, this technology has significant drawbacks: First, pulse jet dust collectors require a continuous supply of high-pressure gas and rely on auxiliary equipment such as air compressors and air tanks, resulting in high system energy consumption and a large footprint. Second, the repeated expansion and contraction of the filter bags during compressed air jetting can easily cause filter fiber breakage, especially when dealing with brittle filter materials such as glass fiber, significantly shortening the filter life. Therefore, a self-cleaning cartridge dust collector is needed to help solve this problem. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a self-cleaning cartridge dust collector. This self-cleaning cartridge dust collector utilizes mechanical vibration to directly act on the support frame housing, eliminating the need for a compressed air system. Compared to pulse dust collectors, which require a continuous supply of high-pressure gas, this reduces energy consumption. Furthermore, the striking component employs a multi-stage spring reset design, ensuring that the striking force is evenly transmitted to the filter screen through the support frame housing, preventing localized stress concentration. In contrast, pulse dust collectors, which rely on compressed air to repeatedly expand and contract the filter bags, are prone to causing filter fiber breakage, thus providing excellent protection for the filter screen.

The dust collection box has an air outlet chamber and a dust collection chamber respectively opened from top to bottom through a partition. The air inlet is connected to the dust collection chamber, the air outlet assembly is connected to the air outlet chamber, and a dust collection assembly connected to the air outlet assembly is installed in the dust collection chamber.

[0006] Furthermore, the dust removal assembly includes a support frame installed below the baffle plate, a filter screen installed on the outer edge of the support frame, a striking chamber opened inside the support frame, a mounting frame fixed inside the striking chamber, a sliding rod installed on the mounting frame, a striking component for auxiliary striking installed on the side of the mounting frame, the sliding rod and the striking component connected by a connecting rod, a cam rotatably installed at the bottom of the striking chamber of the support frame, a roller rotatably installed at the bottom of the sliding rod, the sliding rod and the cam cooperate for transmission, and a servo motor for driving the cam to rotate is installed inside the support frame.

[0007] Furthermore, a fixing frame is fixed near the top of the striking cavity of the support frame, and a plug plate is vertically fixed at the bottom of the fixing frame. The plug plate is installed through the slide rod, and a first pressing spring for assisting the slide rod to press is sleeved on the plug plate.

[0008] Furthermore, the striking assembly includes a mounting cylinder fixed on a mounting bracket, a striking cylinder slidably mounted on the mounting cylinder, a pressure chamber inside the striking cylinder, a sliding rod horizontally fixed inside the pressure chamber, the sliding rod and the sliding bar being hinged together by a connecting rod, and a second pressure spring for assisting the striking cylinder in pushing within the pressure chamber.

[0009] Furthermore, the cam is generally fan-shaped, and the roller is attached to the outer edge of the cam.

[0010] Furthermore, a support leg is fixed at the bottom of the dust collection box, a protective frame is installed at the top of the dust collection box, and a climbing frame is installed on the side of the dust collection box.

[0011] Furthermore, the air outlet assembly includes a connecting cylinder installed on the side of the dust collector box, connecting pipes are installed at equal intervals on the side of the connecting cylinder, and guide tubes are installed at equal intervals at the bottom of the connecting pipes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This specific embodiment is a self-cleaning cartridge dust collector, such as... Figure 1-5As shown, the self-cleaning cartridge dust collector includes a dust collection box 1, an air inlet 4 installed on one side of the dust collection box 1, a funnel-shaped slag outlet 5 installed at the bottom of the dust collection box 1, a butterfly valve 6 installed at the slag outlet 5, a support leg 2 fixed at the bottom of the dust collection box 1, a protective frame 3 installed at the top of the dust collection box 1, and a climbing frame 7 installed on the side of the dust collection box 1. The dust collection box 1 has an air outlet chamber and a dust collection chamber respectively opened from top to bottom through a partition. The air inlet 4 is connected to the dust collection chamber, and the air outlet assembly 8 is connected to the air outlet chamber. The air outlet assembly 8 is installed on the side of the dust collection box 1 near the top. The air outlet assembly 8 includes a connecting cylinder 9 installed on the side of the dust collection box 1, connecting pipes 10 are installed at equal intervals on the side of the connecting cylinder 9, and conduits 11 are installed at equal intervals at the bottom of the connecting pipes 10. The partition has mounting holes for installing the conduits 11 at equal intervals.

[0018] The air outlet assembly 8, with its equidistant arrangement of the connecting cylinder 9 and the duct 11, ensures uniform airflow distribution within the air inlet cavity, preventing filter wear caused by excessively high local wind speeds. The sealing fit between the bottom of the duct 11 and the partition mounting hole prevents unfiltered gas from short-circuiting and directly entering the air outlet cavity.

[0019] The aforementioned dust removal chamber is equipped with a dust removal component 12 that communicates with the air outlet component 8. The dust removal component 12 includes a support frame 13 installed below the baffle plate. A filter screen 14 is installed on the outer edge of the support frame 13. A striking chamber is opened inside the support frame 13, and a mounting frame 15 is fixed inside the striking chamber. A slide rod 16 is installed through the mounting frame 15. A striking component 21 for auxiliary striking is installed on the side of the mounting frame 15. A cam 17 is rotatably installed at the bottom of the striking chamber of the support frame 13. The cam 17 is shaped like a fan blade. The slide rod 16 has a roller 161 rotatably mounted at its bottom. The slide rod 16 and the cam 17 are driven together. The roller 161 fits against the outer edge of the cam 17. The support frame 13 is equipped with a servo motor that drives the cam 17 to rotate. The striking cavity of the support frame 13 is fixed with a fixing frame 18 near the top. The bottom of the fixing frame 18 is vertically fixed with a plug plate 19. The plug plate 19 is installed through the slide rod 16. A first pressing spring 20 is fitted on the plug plate 19 to assist the slide rod 16 in pressing.

[0020] The dust removal component 12 is connected to the dust collection box 1 via a flange. After removing the protective frame 3, the entire support frame 13 can be directly exposed. The filter screen 14 is fixed with a quick-release clamp, and can be replaced without special tools. The mounting cylinder 22 and the striking cylinder 23 in the striking component 21 are fitted with a clearance, and worn parts can be replaced individually.

[0021] The striking assembly 21 includes a mounting cylinder 22 fixed on the mounting bracket 15, a striking cylinder 23 slidably mounted on the mounting cylinder 22, a pressure chamber inside the striking cylinder 23, a sliding rod 25 horizontally fixed inside the pressure chamber, the sliding rod 25 and the sliding rod 16 being hinged together by a connecting rod 26, a second pressure spring 24 assisting the striking cylinder 23 in pushing inside the pressure chamber, and the sliding rod 16 being connected to the striking assembly 21 by the connecting rod 26. The striking component 21 is driven by a servo motor to rotate the cam 17, which directly acts on the support frame 13 housing through mechanical vibration. This eliminates the need for a compressed air system, reducing energy consumption compared to pulse dust collectors which require a continuous supply of high-pressure gas. Furthermore, the striking component 21 employs a multi-stage spring reset design, ensuring that the striking force is evenly transmitted to the filter screen 14 through the support frame 13 housing, thus avoiding localized stress concentration. In contrast, pulse dust collectors, which rely on compressed air to repeatedly expand and contract the filter bag, which can easily lead to fiber breakage, provide excellent protection for the filter screen 14.

[0022] Working principle: Dust-laden gas enters the dust collection chamber of dust collector 1 through air inlet 4. Under the action of gravity, larger coarse dust particles fall directly into the funnel-shaped slag outlet 5, while fine dust rises with the airflow to the dust collection component 12 area. The filter screen 14 on the outer edge of the support frame 13 performs secondary filtration on the airflow to ensure that fine particles are intercepted. The filtered clean gas enters the air outlet chamber through the connecting pipe 10 and the duct 11, and is finally discharged through the air outlet component 8.

[0023] When the filter screen 14 needs cleaning after a period of operation, the servo motor drives the cam 17 to rotate. Its fan-shaped structure forms rolling contact with the roller 161 at the bottom of the slide rod 16. When the cam 17 rotates to the highest point, the slide rod 16 causes the first top pressure spring 20 to be compressed, which in turn causes the slide rod 25 to be pulled through the connecting rod 26, thereby pulling the striking cylinder 23 and compressing the second top pressure spring 24. At this time, the plug plate 19 slides along the slide rod 16, and the fixing frame 18 maintains structural stability. When the cam 17 continues to rotate to the lowest point, the first top pressure spring 20 and the second top pressure spring 24 synchronously reset. The striking cylinder 23 strikes the support frame 13 housing under the action of the spring force, generating vibration waves. This vibration is transmitted to the filter screen 14 through the support frame 13 housing, causing the attached dust to fall off and into the slag outlet 5.

[0024] The butterfly valve 6 installed at the slag outlet 5 controls the slag discharge rhythm by adjusting its opening degree, and together with the funnel-shaped structure, ensures that dust is completely discharged, avoiding secondary dust generation. During equipment operation, the climbing frame 7 and the protective frame 3 provide a maintenance and operation platform, and the support legs 2 ensure overall stability.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
