Description

Technical Field

[0001] The utility model relates to the field of dust collectors, in particular to a multi-stage filtration dust collector. Background Art

[0002] A dust collector is a device that separates dust from flue gas. Filter dust removal is to separate and capture dust by making the dust-containing gas flow through a filter material. A multi-stage filtration dust collector can finely separate dust from waste gas multiple times, enabling the waste gas to meet the emission standards and being widely used in the dust removal of industrial tail gas;

[0003] Now, a multi-stage filtration dust collector is involved. Before the waste gas passes through the filter bag, it first passes through a cyclone separator. Through the centrifugal force generated when the gas-solid mixture rotates at high speed, the dust is separated from the gas flow. However, this causes the gas to spiral upward in the dust collector. When the gas flow drives the dust to be filtered in the filter bag, it will concentrate in one area of the filter bag, resulting in uneven filtration effect. Some areas of the filter bag are already filled with dust, while some areas of the filter bag are not fully utilized, which affects the use of the filter bag and the filtration effect. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a multi-stage filtration dust collector.

[0020] Figures 1 to 4 As shown in the figure, it relates to a multi-stage filter dust collector, including a box body 1. A top cover 2 is detachably installed on the top of the box body 1 in a sealed manner. A first annular slideway 3 and a second annular slideway 4 are fixedly connected to the inner surface of the box body 1 respectively. The second annular slideway 4 is below the first annular slideway 3. A filter bag filtering device is installed on the first annular slideway 3 and the second annular slideway 4 together. A rotating device is installed at the bottom of the top cover 2. By setting the first annular slideway 3 and the second annular slideway 4, the filter bag filtering device can rotate in cooperation with the first annular slideway 3 and the second annular slideway 4.

[0021] The filter bag filtering device includes a chassis 5 slidably connected to the second annular slideway 4. A plurality of openings 6 are formed inside the chassis 5. A filter bag 7 is fixedly connected inside the opening 6. The tops of the plurality of filter bags 7 are fixedly connected to a circular connecting plate 8 together. The set box body 1 is narrower at the bottom than at the top. The set chassis 5 is smaller than the circular connecting plate 8. The set first annular slideway 3 can pass through the chassis 5, so that the chassis 5 can be slidably connected to the first annular slideway 3, and the circular connecting plate 8 can be slidably connected to the second annular slideway 4.

[0022] The filter bag filtering device further includes an arc-shaped cover 9 slidably connected to the first annular slideway 3. The bottom of the arc-shaped cover 9 is fixedly connected to the circular connecting plate 8. The top of the arc-shaped cover 9 is fixedly connected to a pipeline 10. The pipeline 10 penetrates through the arc-shaped cover 9. A toothed ring 11 is fixedly connected to the outer surface of the pipeline 10. By fixedly connecting the arc-shaped cover 9 to the circular connecting plate 8, the gas filtered by the filter bag 7 can be collected inside the arc-shaped cover 9 and discharged from the pipeline 10.

[0023] The rotating device includes a first rotating rod 12 rotatably connected to the bottom of the top cover 2. A gear 13 is fixedly connected to the outer surface of the first rotating rod 12. The gear 13 meshes with the toothed ring 11. A first turntable 14 is fixedly connected to the outer surface of the first rotating rod 12. Four sliding grooves 15 are formed inside the first turntable 14. Since both the gear 13 and the first turntable 14 are fixedly connected to the first rotating rod 12 and the gear 13 meshes with the toothed ring 11, after the first turntable 14 rotates, it can drive the toothed ring 11 to rotate, thereby driving the entire filter bag filtering device to rotate.

[0024] The rotating device further includes a motor 16 fixedly connected to the bottom of the top cover 2. The output shaft of the motor 16 is fixedly connected with a second rotating rod 17. The bottom of the second rotating rod 17 is fixedly connected with a second turntable 18. One side of the second turntable 18 is fixedly connected with an L-shaped rod 19. The L-shaped rod 19 is matched with the chute 15. By driving the second rotating rod 17 and the second turntable 18 to rotate through the motor 16, the L-shaped rod 19 can rotate into the inside of the chute 15. After the L-shaped rod 19 rotates into the inside of the chute 15, the L-shaped rod 19 drives the first turntable 14 to rotate, and the L-shaped rod 19 also slides inside the chute 15. When the first turntable 14 rotates 90°, the L-shaped rod 19 exits the chute 15 and continues to rotate until it rotates into the inside of the chute 15 again.

[0025] The bottom of the box body 1 is fixedly connected with a V-shaped cylinder 20. The outer surface of the V-shaped cylinder 20 is fixedly connected with an air inlet 21. The bottom of the V-shaped cylinder 20 is hermetically and detachably installed with an ash storage box 22. The air flow obliquely enters the inside of the V-shaped cylinder 20 through the air inlet 21, and a cyclone is formed inside the V-shaped cylinder 20. Larger dust rotates on the outside of the cyclone due to centrifugal force. After colliding with the wall of the V-shaped cylinder 20, it falls into the ash storage box 22. The fine dust enters the filter bag filtering device through the rising spiral cyclone.

[0026] The top of the top cover 2 is fixedly connected with an air outlet 23. The air outlet 23 penetrates through the top cover 2. One end of the air outlet 23 is sleeved on the outside of the pipeline 10. The purified gas can be discharged through the air outlet 23 sleeved on the outside of the pipeline 10.

[0027] When using a multi-stage filtration dust collector, first turn on the motor 16. The motor 16 drives the second rotating rod 17 and the second turntable 18 to rotate, so that the L-shaped rod 19 can rotate into the chute 15. After the L-shaped rod 19 rotates into the chute 15, the L-shaped rod 19 drives the first turntable 14 to rotate. The first turntable 14 drives the gear 13 to rotate. The gear 13 meshes with the toothed ring 11, and the chassis 5 is slidably connected to the first annular slideway 3. The circular connecting plate 8 is slidably connected to the second annular slideway 4, so that the filter bag filtering device can rotate. After the first turntable 14 rotates 90°, the L-shaped rod 19 exits the chute 15 and continues to rotate until the L-shaped rod 19 rotates into the chute 15 again. The filter bag filtering device can rotate intermittently by 90°. Then, let the waste gas enter from the air inlet 21. The air flow obliquely enters the interior of the V-shaped cylinder 20 through the air inlet 21, and a cyclone is formed inside the V-shaped cylinder 20. Larger dust rotates on the outside of the cyclone due to centrifugal force. After colliding with the wall of the V-shaped cylinder 20, it falls into the ash storage box 22. The fine dust enters the filter bag filtering device through the rising spiral cyclone. Through the intermittently rotating filter bag filtering device, the waste gas can be filtered evenly. The gas filtered by the filter bag filtering device gathers in the arc-shaped cover 9 and is discharged from the filter bag filtering device through the pipe 10, and then discharged from the air outlet 23 outside the multi-stage filtration dust collector.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
