Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device which is convenient to clean. Background Art

[0002] Industrial silicon, also known as semi-metallic silicon or metallic silicon, is a product mainly smelted from silica and carbonaceous reducing agents in a submerged arc furnace. Its main component is silicon, with a content of about 98%, and the rest contains impurities such as iron, aluminum, and calcium. As an important chemical raw material, industrial silicon has a wide range of application fields. It not only plays an important role in the chemical field but also plays a key role in high-tech industries. Therefore, the processing and production of industrial silicon are extremely common. During its processing and production process, a large amount of dust impurities will be generated, so dust removal equipment is needed. When the dust removal equipment works, it needs to be filtered through a filter screen. After the filter screen filters for a period of time, it will slowly become saturated and needs to be cleaned to continue the normal filtering work.

[0003] For some traditional dust removal devices, the cleaning work of their filtering structures mostly relies on manually disassembling the housing of the filtering structure by workers. After the filter screen structure is disassembled, the cleaning work can be carried out. Such an operation method is very time-consuming and laborious. Moreover, during the production of industrial silicon, when the amount of dust is large, the cleaning frequency of the filtering structure will increase, and disassembly and assembly are required for each cleaning. Such an operation method has great inconvenience. Summary of the Utility Model

[0026] Refer to Figures 1-4, an embodiment provided by the present utility model: a dust removal device convenient for cleaning, including a fixing frame 1. An inner cavity 2 is arranged inside the fixing frame 1. A filtering frame 3 is arranged inside the inner cavity 2. The filtering frame 3 is in the form of a filter screen. An air inlet 6 and an air outlet 7 are respectively arranged at the bottom and top of the fixing frame 1. The air inlet 6 can be butted with a dust removal pipeline, and the air outlet 7 is butted with an air extraction and dust removal device. An elevating frame 8 sleeved outside the filtering frame 3 is arranged inside the inner cavity 2. A groove 9 is arranged on the inner wall of the inner cavity 2. A screw rod 10 is rotatably connected inside the groove 9. A first motor 11 with an output end fixedly connected to the top end of the screw rod 10 is arranged inside the fixing frame 1. A nut block 12 is threadedly sleeved on the screw rod 10. The connection position between the screw rod 10 and the groove 9 is positioned and installed through a bearing. The nut block 12 and the groove 9 are arranged in a nested sliding fit. The nut block 12 is fixedly connected to the elevating frame 8. A rotating frame 13 is arranged inside the elevating frame 8. A brush hair 14 is fixedly connected to the rotating frame 13. The brush hair 14 is arranged in a fitting manner with the filtering frame 3. A limiting sliding groove 16 is arranged on the elevating frame 8. A limiting sliding block 15 fixedly connected to the rotating frame 13 and nested and slidably fitted with the limiting sliding groove 16 is arranged on the rotating frame 13. The cross sections of the limiting sliding block 15 and the limiting sliding groove 16 are both in a conical form. The conical limiting sliding block 15 structure can stably connect the rotating frame 13 and the elevating frame 8 together. A first fixing groove 17 is arranged on the limiting sliding block 15. A rack 18 is fixedly connected to the inner wall of the first fixing groove 17. The first fixing groove 17 and the rack 18 are annular. A second fixing groove 19 is arranged on the inner wall of the limiting sliding groove 16. A gear 20 is rotatably connected inside the second fixing groove 19. The gear 20 is meshed with the rack 18. A second motor 21 with an output end fixedly connected to the central axis of the gear 20 is arranged inside the elevating frame 8. The second motor 21 drives the gear 20 to rotate. The gear 20 drives the rack 18 to move, thereby driving the rotating frame 13 to rotate. The rotating frame 13 can drive the brush hair 14 to move, and the brush hair 14 can brush the filtering frame 3 to sweep the impurities on its surface.

[0027] A threaded groove 4 is arranged at the bottom of the fixing frame 1. A sealing frame 5 is threadedly connected inside the threaded groove 4. The air inlet 6 is located on the sealing frame 5. The setting of this structure can not only stably seal the entire fixing frame 1, but also be conveniently opened to facilitate regular centralized cleaning of impurities.

[0028] A guiding block 22 is fixedly connected to the outer surface of the elevating frame 8. A guiding groove 23 is arranged on the inner wall of the inner cavity 2. The guiding block 22 and the guiding groove 23 are arranged in a nested sliding fit. The setting of the guiding structure can assist in ensuring the smoothness of the lifting operation of the elevating frame 8.

[0029] Working principle: When using the dust removal device that is convenient for cleaning, during dust removal, when the air extraction device works, it drives the air flow to carry impurities through the air inlet 6 into the inner cavity 2. After being filtered by the filter rack 3, the air flow is discharged from the air outlet 7. When it is necessary to clean the filter rack 3, start the second motor 21. The second motor 21 drives the gear 20 to rotate. The gear 20 drives the rack 18 to move. The rack 18 drives the rotating frame 13 to rotate. The rotating frame 13 brushes the filter rack 3. Start the first motor 11. The first motor 11 drives the screw rod 10 to rotate. The screw rod 10 drives the screw block 12 to descend. The screw block 12 drives the lifting frame 8 to descend. The lifting frame 8 drives the rotating frame 13 to descend. The rotating frame 13 then drives the brush bristles 14 to descend. Thus, the impurities adhering to the filter can be swept down from top to bottom to complete the cleaning work of the filter rack 3.
