Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for fertilizer production. Background Technology
[0002] Fertilizers are substances that provide the nutrients needed for crop growth and development, improve soil properties, and increase crop yield and quality; they are generally classified into organic fertilizers, inorganic fertilizers, and biological fertilizers. Modern fertilizer production typically uses automated continuous equipment, where raw materials are mixed and processed sequentially through various steps to ultimately obtain the desired granular or powdered product. Because raw materials, intermediate materials, and products inevitably contain some fine particulate matter during fertilizer processing, the production workshop is subject to long-term dust pollution, posing significant environmental problems. Prolonged exposure not only harms the health of workers but also easily damages machinery due to dust accumulation, causing economic losses and disrupting production. Therefore, dust collection equipment, such as baghouse dust collectors, is usually installed in production workshops.
[0003] However, when existing baghouse dust collectors filter dust generated during fertilizer production, the air contains not only dust but also some chemical vapors. When this mixed gas passes through the filter bags, the chemical vapors condense on the surface of the bags to form crystals, which then combine with the dust adhering to the surface of the bags to form firmly hardened dirt. Simply using the blower device in the baghouse dust collector to blow air onto the bags to remove dust is ineffective and cannot effectively remove the hardened dirt from the surface of the bags, thus affecting the dust removal efficiency of the bags. Utility Model Content
[0004] This utility model discloses a dust removal device for fertilizer production, which solves the problem of poor dust removal effect of the jet blowing device in bag dust collector on the surface of the bag.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A dust removal device for fertilizer production includes a housing with a sealing plate fixed inside. A dust collection bag is connected to the bottom of the sealing plate, and a blow pipe is provided above the sealing plate. A motor is located below the dust collection bag inside the housing, and a connector connected to the bottom of the dust collection bag is provided at the output end of the motor. The motor drives the connector to rotate so that the dust collection bag rotates clockwise or counterclockwise.
[0007] Compared with the prior art, the present invention has the following beneficial effects:
[0008] When hardened dirt forms on the surface of the dust collection bag, the dust collection bag is twisted as the motor drives the connecting parts to rotate. Repeated clockwise and counterclockwise twisting by the motor tears the hardened dirt off the surface of the dust collection bag. Then, high-pressure gas is sprayed into the dust collection bag through the blowpipe, causing the hardened dirt to fall off. This invention effectively treats the hardened dirt on the surface of the dust collection bag by tearing and loosening it, and the high-pressure gas from the blowpipe ensures continuous and effective dust removal, reducing maintenance time and costs.

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0013] like Figure 1 and Figure 2 As shown, this utility model provides a dust removal device for fertilizer production, including a box 1, a sealing plate 2 fixed inside the box 1, a dust collection bag 21 connected to the bottom of the sealing plate 2, a blow pipe 6 above the sealing plate 2, a motor 3 located below the dust collection bag 21 inside the box 1, and a connector connected to the bottom of the dust collection bag 21 at the output end of the motor 3. The motor 3 drives the connector to rotate so that the dust collection bag 21 rotates clockwise or counterclockwise. The sealing plate 2 is located between the air inlet and the air outlet of the housing 1, with the air inlet located below the air outlet. The motor 3 is a servo motor. After starting the motor 3, the connecting parts can rotate clockwise or counterclockwise, which in turn drives the dust collection bag 21 to rotate clockwise or counterclockwise, so that the hardened dirt on the surface of the dust collection bag 21 is torn and loosened and falls downward. One end of the blow pipe 6 extends to the outside of the housing 1 and is connected to an external air pump. When the blow pipe 6 sprays high-pressure gas into the dust collection bag 21, it can effectively cause the hardened dirt that has been torn or loosened to fall off the surface of the dust collection bag 21 and fall downward.
[0014] like Figure 1 and Figure 2As shown, the connector includes a column 4 fixed to the shaft of the motor 3, a circular plate 41 fixed on the column 4, and a set of fixing rods 42 fixed on the circular plate 41 and connected to the bottom of the dust collection bag 21. After the motor 3 starts, it can drive the column 4 to rotate, and the column 4 can drive the set of fixing rods 42 to rotate through the circular plate 41. After the fixing rods 42 rotate, the dust collection bag 21 will twist. A fixing ring is fixed to the top of the dust collection bag 21. The fixing ring is connected to the bottom of the sealing plate 2 by bolts, and a screw is threaded on the fixing rod 42. The large head of the screw is located inside the dust collection bag 21, and the bottom end of the screw passes through the bottom of the dust collection bag 21 and is threaded to the top of the fixing rod 42 to complete the fixation of the dust collection bag 21. When the dust collection bag 21 needs to be disassembled and replaced, it is only necessary to remove the bolt on the fixing ring first, and then remove the screw threaded to the fixing rod 42. The disassembly process of the dust collection bag 21 is simple and quick. The number of fixing rods 42 is at least three.
[0015] like Figure 1 As shown, a connecting rod 5 is fixed to the bottom of the sealing plate 2, and a contact rod 51 is fixed to the side of the connecting rod 5 near the dust collection bag 21; a nozzle 61 corresponding to the connection point between the sealing plate 2 and the dust collection bag 21 is connected to the blowing pipe 6. The number of dust collection bags 21 is at least two (e.g., Figure 1 As shown in the diagram, the motor 3 and the blowpipe 6 also have two nozzles 61. There are two sets of connecting rods 5. The two dust collection bags 21 are located inside the two sets of connecting rods 5 respectively. There is only one connecting rod 5 between the two dust collection bags 21. There are contact rods 51 on both sides of the connecting rod 5. There are several contact rods 51 on the connecting rod 5. When the nozzle 61 blows high-pressure gas into the dust collection bag 21, the dust collection bag 21 can start to expand (after the dust collection bag 21 is twisted and restored), so that the surface of the dust collection bag 21 can collide with the contact rod 51. The hardened part after the dust collection bag 21 is twisted and torn can directly contact the contact rod 51, and it can be easily punctured and fallen off.
[0016] like Figure 1 and Figure 2 As shown, a movable plate 31 is slidably connected inside the housing 1, and a motor 3 is fixed on the movable plate 31. An electric telescopic rod 7 for driving the movable plate 31 to move laterally is fixed inside the housing 1. There are two electric telescopic rods 7, each used to drive the two movable plates 31 to move. When the electric telescopic rods 7 are activated to repeatedly move the movable plates 31, the dust collection bag 21 can collide with the contact rod 51. This allows dust to fall off the dust collection bag 21 promptly when it enters the housing 1, reducing the formation of subsequent caking.
[0017] Alternatively, when the dust collection bag 21 needs to be cleaned, after the dust collection bag 21 is twisted, the electric telescopic rod 7 can be activated to make the dust collection bag 21 swing laterally, so that the dust collection bag 21 hits the contact rod 51, so that the hardened dirt can be better removed.
[0018] like Figure 1 and Figure 2 As shown, the telescopic end of the electric telescopic rod 7 is fixed with a push plate 71 connected to the moving plate 31, and the fixed end of the electric telescopic rod 7 is fixed with a fixing plate 72 connected to the housing 1. A slide rail 8 is provided on the inner wall of the housing 1, and a slider connected to the slide rail 8 is fixed on the moving plate 31. After the electric telescopic rod 7 is started, the push plate 71 can drive the moving plate 31 to slide laterally, so that the slider on the moving plate 31 moves within the slide rail 8. The fixing plate 72 can fix the electric telescopic rod 7 below the moving plate 31 to prevent dirt falling downwards from contacting the electric telescopic rod 7.
[0019] like Figure 1 and Figure 2 As shown, a cover 32 is fixed to the top of the movable plate 31 to cover the motor 3. The cover 32 is funnel-shaped. The cover 32 can cover the motor 3 to prevent dirt from accumulating on the motor 3. The cover 32 is also connected to a flexible hose (not shown in the figure) that runs through the housing 1 to allow better ventilation inside the cover 32 and prevent the temperature inside the cover 32 from getting too high.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
