Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, in particular to an integrated two-stage bag filter cartridge dust collector. Background Art

[0002] The integrated two-stage bag filter cartridge dust collector is a highly efficient dust removal equipment that combines the advantages of bag dust collector and cartridge dust collector, and achieves efficient purification of dust-laden gas through a two-stage filtration system.

[0003] During the use of the existing integrated two-stage bag filter dust collector, a large amount of dust will adhere to the first-stage bag filter after long-term use, which can easily cause the first-stage bag filter to be blocked and affect the use of the second-stage bag filter.

[0004] In response to the above technical problems, the applicant has retrieved some existing technologies to achieve the cleaning of the first-level bag filter cartridge. For example, the patent publication number is CN218357991U. Its main technical means is that there are jet pipes above the two support plates. The two jet pipes are respectively connected to the corresponding air inlet pipes. The outer surfaces of the two jet pipes are fixedly connected with pulse nozzles distributed at equal distances. Each pulse nozzle is located directly above the corresponding bag filter cartridge. The pulse nozzle is located directly above the bag filter cartridge, which allows the pulse airflow to enter the bag filter cartridge and remove the dust attached to the outer surface of the bag filter cartridge. After analysis by the applicant, the disadvantage of this technical solution is that dust easily accumulates on the bag filter cartridge. These dusts have strong adhesion. If only the pulse airflow is used for cleaning, these dusts with strong adhesion cannot be cleaned off, thereby affecting the filtering effect of the first bag filter cartridge and the use of the second-level bag filter cartridge. Utility Model Content

The dust collector also includes:

[0035] The collar 13 is sleeved on the outer periphery of the primary bag filter cartridge 9. The number of collars 13 is the same as the number of the primary bag filter cartridge 9. Adjacent collars 13 are fixedly connected by a connecting plate 132.

[0036] The slave gear 134 has a rotation groove 137 formed in the collar 13, and the slave gear 134 is movably sleeved in the rotation groove 137;

[0037] The protrusion 135 is provided with an annular notch 133 on the inner side of the collar 13, and a plurality of protrusions 135 are provided on the portion of the gear 134 exposed from the annular notch 133. The protrusions 135 abut against the outer surface of the first-stage bag filter cartridge 9, causing the corresponding position of the first-stage bag filter cartridge 9 to be concave inward;

[0038] Driving member 15 is installed on the cover plate 10. A screw 151 is installed on the output end of the driving member 15. The screw 151 passes through the connecting plate 132 and is threadedly connected to the connecting plate 132.

[0039] The linkage mechanism 16 is a connecting shell 14 installed on the collar 13 , and the linkage mechanism 16 is installed in the connecting shell 14 . The linkage mechanism 16 is in transmission connection with the slave gear 134 , and the linkage mechanism 16 is connected to a second driving member 17 .

[0040] In one case of this embodiment, a first-level air inlet hole 5 is provided on the first-level air inlet bin 3, a second-level air inlet hole 41 is opened on the second-level air inlet bin 4, a first-level ash hopper 7 is installed at the bottom of the first-level dust removal shell 1, a second-level ash hopper 8 is installed at the bottom of the second-level dust removal shell 2, and an exhaust pipe 6 is installed at the top of the second-level dust removal shell 2; the driving member 15 and the driving member 2 17 can both be motors, or other components that can drive the screw 151 to rotate.

[0041] In actual application of this embodiment, the flue gas enters the first-level air inlet bin 3 through the first-level air inlet hole 5, enters the first-level dust removal shell 1 through the gap between the bottom of the first-level dust removal shell 1 and the first-level ash hopper 7, and filters the dust in the flue gas through the first-level cloth bag filter cartridge 9. When the dust filtered out of the first-level cloth bag filter cartridge 9 accumulates together and blocks the first-level cloth bag filter cartridge 9, the pulse jet component 19 is first used to jet into the first-level cloth bag filter cartridge 9 to clean up part of the dust and drop it into the first-level ash hopper 7 for discharge. At the same time, the screw 151 is rotated by the driving member 15, and the guide of the guide rod 152 is used to move the several rings 13 upward or downward, and the first-level cloth bag filter cartridge 9 is squeezed by the protrusion 135, so that the first-level cloth bag filter cartridge 9 is The bag filter cartridge 9 is squeezed and concave inward, so that the accumulated dust will slowly open up from the inside of the first-level bag filter cartridge 9, so that the dust with strong adhesion and accumulated together can be cleaned up, thereby improving the dust cleaning effect. In this way, it is not easy to affect the filtering effect of the first-level bag filter cartridge 9, nor is it easy to affect the use of the second-level bag filter cartridge 11. At the same time, the linkage mechanism 16 is driven by the driving member 2 17 to rotate the slave gear 134, so that the protrusion 135 can rotate with the slave gear 134, so that the protrusion 135 can contact all positions on the first-level bag filter cartridge 9 as much as possible, and can clean the dust at all positions inside the first-level bag filter cartridge 9, further improving the dust cleaning effect.

[0042] Furthermore, the linkage mechanism 16 includes several main gears 161 and several linkage parts 162. One main gear 161 and one linkage part 162 are installed in the connecting shell 14 as a group. The number of groups of main gears 161 and linkage parts 162 is the same as the number of primary bag filter cartridges 9. Each group of main gears 161 and linkage parts 162 corresponds to one primary bag filter cartridge 9. The main gear 161 and the slave gear 134 on the corresponding collar 13 are engaged with each other. Several main gears 161 are synchronously driven through the linkage parts 162, and one group of main gears 161 and linkage parts 162 is connected to the driving member 2 17.

[0043] In one case of this embodiment, the linkage member 162 may be composed of a driving wheel, a driven wheel, and a belt connecting the driving wheel and the driven wheel, and the multiple main gears 161 may rotate synchronously through the linkage member 162.

[0045] like Figure 4-Figure 6 As shown, cleaning rings 131 are movably installed on the top and bottom of the ring 13, and a brush 1311 is provided on the inner side of the cleaning ring 131.

[0046] In actual application of this embodiment, when the ring 13 moves upward or downward, it drives the cleaning ring 131 to move upward or downward, so that the brush 1311 brushes the surface of the first-level bag filter 9, and cleans the dust from the inside of the first-level bag filter 9, further improving the dust cleaning effect.

[0047] Furthermore, the protrusion 135 is fixedly connected to the cleaning rings 131 at upper and lower positions via two connecting rods 136 .

[0048] In actual application of this embodiment, the gear 134 rotates or drives the protrusion 135 to rotate, and the protrusion 135 drives the cleaning ring 131 to rotate through the connecting rod 136, so that the cleaning ring 131 rotates during the upward or downward movement, so that the brush 1311 rotates and contacts the surface of the first-level bag filter 9, further improving the dust cleaning effect.

[0049] like Figure 8 As shown, the second cover plate 12 is movably mounted on the secondary dust removal housing 2 , and a shaking mechanism 18 is mounted on the second cover plate 12 .

[0051] In actual application of this embodiment, the flue gas that has passed through the first-level bag filter cartridge 9 enters the second-level dust removal housing 2 through the second-level air inlet hole 41, and then passes through the second-level bag filter cartridge 11 for a second filtration. The filtered dust will remain on the inner wall of the second-level bag filter cartridge 11, and the filtered flue gas is discharged through the exhaust pipe 6. At the same time, the cover plate 12 is shaken up and down by the shaking mechanism 18, so that the dust remaining on the inner wall of the second-level bag filter cartridge 11 is shaken down and falls into the second-level ash hopper 8 for discharge, so that the second-level bag filter cartridge 11 is not easily blocked during use, thereby improving the dust removal effect.

[0052] Working principle: The flue gas enters the first-level air inlet bin 3 through the first-level air inlet hole 5, and enters the first-level dust removal shell 1 through the gap between the bottom of the first-level dust removal shell 1 and the first-level ash hopper 7, and filters the dust in the flue gas through the first-level bag filter 9. When the dust filtered out of the first-level bag filter 9 accumulates together and blocks the first-level bag filter 9, the pulse jet component 19 is first used to jet into the first-level bag filter 9, and some dust is cleaned down and falls into the first-level ash hopper 7 for discharge. At the same time, the screw 151 is rotated by the driving member 15, and the guide of the guide rod 152 is used to move the several rings 13 upward or downward, and the first-level bag filter 9 is squeezed by the protrusion 135, so that the first-level bag filter 9 is squeezed. The position is recessed inward, so that the accumulated dust will slowly open from the inside of the first-level bag filter cartridge 9, thereby cleaning up the dust with strong adhesion and accumulated together. At the same time, the linkage mechanism 16 drives the slave gear 134 to rotate through the driving member 2 17, so that the protrusion 135 will follow the rotation of the slave gear 134, so that the protrusion 135 can contact all positions on the first-level bag filter cartridge 9 as much as possible, and can clean the dust at all positions inside the first-level bag filter cartridge 9. When the ring 13 moves up and down and the protrusion 135 rotates, the cleaning ring 131 rotates while moving up and down, and the cleaning ring 131 contacts the outer surface of the first-level bag filter cartridge 9, and cleans the dust from the inside of the first-level bag filter cartridge 9.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
