DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Embodiment one: please refer to Figures 1-6 The existing dust removal device can only be processed in the non-working state when cleaning the filter plate, which is inconvenient for processing the filter plate during on-site construction. When the filter plate is blocked, it needs to be cleaned after stopping, thereby reducing the overall on-site construction efficiency. In order to solve this technical problem, the embodiment discloses the following technical content: a dustproof alarm device suitable for concrete mixing station powder tank material, which comprises an induced draft fan 1. One side of the induced draft fan 1 is provided with an exhaust pipe 2, and the other side of the induced draft fan 1 is connected with a filter box 3 through a pipeline. The side of the filter box 3 is connected with the inside of the powder tank through a suction pipe 4. The inside of the powder tank is provided with a dust concentration sensor 5. The dust concentration sensor 5, an alarm 6, an induced draft fan 1 and a servo motor 7 are electrically connected. The alarm 6 is installed at the upper end of the filter box 3. The servo motor 7 is fixedly installed at the side of the filter box 3. The output end of the servo motor 7 is provided with a filter cartridge 8. The filter cartridge 8 is installed on a bearing block 9. The bearing block 9 is fixed in the inside of the filter box 3. The filter box 3 is provided with a center rod 10. The center rod 10 penetrates the middle part of the filter cartridge 8. The side of the center rod 10 is fixedly connected with a brush 11. The filter cartridge 8 is uniformly provided with a plurality of holes in the circumferential direction. The outer wall of the filter cartridge 8 is in close contact with the bearing block 9. The filter cartridge 8 can rotate on the center rod 10. The side of the center rod 10 is uniformly provided with a plurality of brushes 11. The brushes 11 are made of elastic rubber material.

[0032] When the inside of the powder tank is being stirred, the dust concentration inside the powder tank can be monitored by the dust concentration sensor 5, and when the dust concentration exceeds the standard, the dust concentration sensor 5 can control the alarm 6, the induced draft fan 1 and the servo motor 7 to be turned on. When the alarm 6 is turned on, an alarm is given to the crowd to remind them, and when the induced draft fan 1 is turned on, dust can be sucked by the suction pipe 4. After the dust gas enters the inside of the filter box 3, the dust impurities in the gas can be filtered by the filter cylinder 8. The filtered gas is discharged outward through the exhaust pipe 2. After the servo motor 7 is turned on, the filter cylinder 8 can be rotated. After the filter cylinder 8 is rotated, the impurities on the surface of the filter cylinder 8 can be scraped off by the supporting block 9. The impurities and dust attached to the surface of the filter cylinder 8 can be cleaned by the supporting block 9. After the filter cylinder 8 is rotated, the holes on the filter cylinder 8 coincide with the bristles 11 on the side of the center rod 10. After the bristles 11 are elastically reset, the bristles 11 can push the impurities stuck in the holes outward, realizing automatic cleaning of the holes.

[0033] In this embodiment, the following technical content is disclosed: The side opposite to the brush 11 of the center rod 10 is provided with a vibration component 12. The vibration component 12 comprises a hitting rod 121, an auxiliary spring 122, a first magnetic block 123 and a second magnetic block 124. The hitting rod 121 is installed on the center rod 10 and connected to the center rod 10 through the auxiliary spring 122. The first magnetic block 123 is fixedly installed on the hitting rod 121. The second magnetic block 124 is arranged on the side of the first magnetic block 123. The second magnetic block 124 is fixedly arranged on the inside side of the filter cylinder 8. The end of the hitting rod 121 away from the center rod 10 is in close contact with the inner wall of the filter cylinder 8. The hitting rod 121 and the center rod 10 constitute an elastic extension structure through the auxiliary spring 122. The first magnetic block 123 on the hitting rod 121 has the same magnetism as the second magnetic block 124 inside the filter cylinder 8. The second magnetic block 124 is evenly distributed at equal angles on the inside side of the filter cylinder 8.

[0034] When the filter cylinder 8 rotates on the center rod 10, the rotation of the filter cylinder 8 can drive the second magnetic block 124 to rotate synchronously. When the second magnetic block 124 and the first magnetic block 123 on the hitting rod 121 approach each other, the repulsive magnetic force between them can make the hitting rod 121 move towards the center rod 10. When the second magnetic block 124 on the filter cylinder 8 and the first magnetic block 123 on the hitting rod 121 move away from each other after the filter cylinder 8 rotates, the hitting rod 121 is reset and rebounds under the action of the auxiliary spring 122. The reset hitting rod 121 can hit the filter cylinder 8. The vibration generated by the hitting of the filter cylinder 8 can reduce the adhesion of dust and impurities on the filter cylinder 8, facilitating better cleaning of the dust and impurities on the filter cylinder 8.
