Abstract
Description
Technical Field
[0001] This utility model belongs to the field of compound fertilizer dust removal technology, specifically relating to a compound fertilizer dust collection device. Background Technology
[0002] Compound fertilizer, as an important type of fertilizer in agricultural production, has advantages such as high nutrient content, few by-products, and good physical properties. It plays a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. With the acceleration of agricultural modernization, the demand for compound fertilizer is increasing daily. Currently, the production of compound fertilizer mainly adopts processes such as granulation, slurry, and blending. In the process of compound fertilizer production, dust is generated in various stages such as raw material crushing, screening, mixing, granulation, drying, cooling, screening, and packaging. This dust not only contains effective components such as nitrogen, phosphorus, and potassium in compound fertilizer, but may also contain some harmful substances, such as heavy metals and harmful microorganisms. The diffusion of dust can cause serious pollution to the production environment, affect the health of workers, and lead to occupational diseases such as respiratory diseases and skin diseases.
[0003] To address the dust pollution problem in the compound fertilizer production process, some dust collection devices have emerged on the market. These devices use fans in conjunction with filters to remove dust. However, in practical applications, it has been found that existing dust collection devices carry away a large amount of dust when the filters are removed for cleaning and replacement. When the filters are bumped, dust falls off, causing environmental pollution and making cleaning and replacement inconvenient. Therefore, this application proposes a compound fertilizer dust collection device. Utility Model Content

[0014] Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the installation of a fan, a first dust filter, and a second dust filter, with the dust collection box and suction duct suspended on the compound fertilizer production line (processes such as crushing, screening, and mixing), allows the fan to be activated during compound fertilizer production. The dust generated during production is drawn into the dust collection box through the suction hood and suction duct. Furthermore, the multi-stage filtration system, consisting of the first, second, and third filters and activated carbon filler, effectively collects the dust within the dust collection box, resulting in excellent dust collection efficiency. This significantly reduces the harm caused by dust emissions into the air to the environment and human health.
[0017] This invention features a structure where the first, second, and third filters, along with activated carbon filler, are distributed on both sides of the fan. After dust is drawn into the dust collection box, the first filter effectively filters and blocks it, reducing its impact on the fan.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This embodiment provides a compound fertilizer dust collection device, the structural schematic diagram of which is shown below. Figures 1-4 As shown, the dust collection box 1 is included. One end of the dust collection box 1 is connected to an air intake pipe 2. The end of the air intake pipe 2 away from the dust collection box 1 is bent downward and equipped with an air intake hood 3. The other end of the air intake pipe 2 is connected to an exhaust pipe 4. A ring seat 9 is provided inside the dust collection box 1. A fan 10 is installed inside the ring seat 9. A first dust filter 5 and a second dust filter 6 are also provided inside the dust collection box 1. The first dust filter 5 and the second dust filter 6 are distributed on both sides of the ring seat 9. The first dust filter 5 includes a first frame plate 11 that is movably embedded in the dust collection box 1. The first frame plate 11 is located on the side of the ring seat 9 facing the air intake pipe 2. A first filter screen 12 is provided inside the first frame plate 11. The second dust filter element 6 includes a second frame plate 13 disposed inside the dust collection box 1. The second frame plate 13 is located on the side of the ring seat 9 facing the exhaust duct 4. A second filter screen 14 is disposed inside the second frame plate 13 on the side facing the ring seat 9. A third filter screen 15 is disposed inside the second frame plate 13 on the side facing the exhaust duct 4. Activated carbon filler 16 is filled between the second filter screen 14 and the third filter screen 15. The filter pores of the first filter screen 12, the second filter screen 14, and the third filter screen 15 gradually decrease in size. Through this structural design, the dust collection box 1 and the suction duct 2 are suspended on the compound fertilizer production line (crushing, screening, mixing, etc.). During the compound fertilizer production process, the fan 10 is activated to draw in air. The dust generated during the compound fertilizer production process is drawn into the dust collection box 1 by the suction hood 3 and the suction duct 2. Under the multi-stage filtration and barrier of the first filter screen 12, the second filter screen 14, the third filter screen 15, and the activated carbon filler 16, the dust can be collected in the dust collection box 1, which can effectively reduce the problem of dust emission into the air and the harm to the environment and human health.
[0026] In this embodiment, a dust discharge plate 8 is provided at the bottom of the side wall of the dust collection box 1. After opening the dust discharge plate 8, the dust collected inside the dust collection box 1 can be cleaned. Ear blocks 7 are provided at the four corners of the top of the dust collection box 1. Through holes are opened on the ear blocks 7 for hoisting the dust collection box 1.
[0027] Furthermore, in this embodiment, the top ends of the first frame plate 11 and the second frame plate 13 both penetrate the top wall of the dust collection box 1 and are connected to an end plate 17. A sealing ring 20 is provided on the lower surface of the end plate 17 for sealing between the end plate 17 and the dust collection box 1. The end plate 17 is bolted to the top wall of the dust collection box 1. After the end plate 17 is removed from the top of the dust collection box 1, the first frame plate 11 and the second frame plate 13 can be pulled out of the dust collection box 1 to clean and replace the first filter screen 12, the second filter screen 14, the third filter screen 15 and the activated carbon filler 16. A rubber pillow block 21 is provided at the bottom of the first frame plate 11 and the second frame plate 13. The rubber pillow block 21 is pressed against the inner bottom wall of the dust collection box 1 for sealing between the first frame plate 11 and the second frame plate 13 and the inner bottom wall of the dust collection box 1.
[0028] In a further embodiment, the first frame plate 11 is fitted to the ring seat 9, the first filter screen 12 is flush with the side of the first frame plate 11 away from the ring seat 9, a first functional block 18 is fixed on the inner top wall of the dust collection box 1, the first functional block 18 is movably fitted with the side of the first frame plate 11 away from the ring seat 9, the second filter screen 14 and the third filter screen 15 are flush with the side of the second frame plate 13, and a second functional block 19 is fixed on the inner top wall of the dust collection box 1, the second functional block 19 is distributed on the side of the second frame plate 13 facing the ring seat 9, and the second functional block 19 is flush with the side of the second frame plate 13 facing the ring seat 9. 3. The side is movable and fits together. The first functional block 18 and the second functional block 19 are both set as triangular structures. With this structural design, when the first frame plate 11 and the second frame plate 13 are pulled upward from the top of the dust collection box 1, the first functional block 18 can scrape off the dust on the surface of the first filter screen 12, and the second functional block 19 can scrape off the dust on the surface of the second filter screen 14. This facilitates the replacement and cleaning of the first filter screen 12, the second filter screen 14, the third filter screen 15 and the activated carbon filler 16, and also avoids dust being carried out of the dust collection box 1 during the replacement process and affecting the surrounding environment.
[0029] Working Principle: During operation, the dust collection box 1 and the suction duct 2 are suspended on the compound fertilizer production line (processes such as crushing, screening, and mixing), with the suction hood 3 positioned above the production line. During compound fertilizer production, the fan 10 is activated to draw in the dust generated during production, which is then drawn into the dust collection box 1 through the suction hood 3 and the suction duct 2. Through multi-stage filtration using the first filter 12, second filter 14, third filter 15, and activated carbon filler 16, the dust is effectively collected within the dust collection box 1, resulting in excellent dust collection efficiency. This effectively reduces the harm to the environment and human health caused by dust emissions into the air. Furthermore, since the first filter 12, second filter 14, third filter 15, and activated carbon filler 16 are distributed on both sides of the fan 10, the dust, after being drawn into the dust collection box 1, is further filtered... The filter 12 can filter and block dust first, reducing the impact of dust on the fan 10. The second filter 14, the third filter 15 and the activated carbon filler 16 can filter and purify the remaining fine dust and impurities in the airflow, improving the durability of the equipment. In addition, by setting the first functional block 18 and the second functional block 19, the first frame plate 11 and the second frame plate 13 can be pulled out from the top of the dust collection box 1. The first functional block 18 can scrape off the dust on the surface of the first filter 12 and the second functional block 19 can scrape off the dust on the surface of the second filter 14. This facilitates the replacement and cleaning of the first filter 12, the second filter 14, the third filter 15 and the activated carbon filler 16, and avoids dust being carried out of the dust collection box 1 during the replacement process, affecting the surrounding environment. Opening the dust discharge plate 8 can centrally clean the dust collected inside the dust collection box 1.
[0030] All technical features in this embodiment can be freely combined according to actual needs.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
