Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, and more specifically, to a fertilizer dust removal device. Background Technology

[0002] Fertilizer production refers to the process of converting various raw materials into fertilizers through chemical synthesis, physical treatment, biological fermentation, and other methods. The main purpose of fertilizer production is to provide plants with the necessary nutrients to promote their growth and development. The fertilizer production process involves multiple steps, such as raw material preparation, batching, mixing, granulation, drying, screening, and packaging. Dust is generated during these steps and needs to be treated.

[0003] A search revealed that utility model patent CN219355623U discloses a dust removal device for fertilizer processing, including a plate-type medium-efficiency air filter, a stainless steel fine-pore filter plate, a HEPA high-efficiency filter plate, a threaded positioning rod, an extension plate, and an axial flow fan. The axial flow fan is mounted on the right side of the dust removal chamber, and a HEPA high-efficiency filter plate is fitted to the left side of the axial flow fan. A plate-type medium-efficiency air filter is fitted to the left side of the HEPA high-efficiency filter plate, and a stainless steel fine-pore filter plate is fitted to the left side of the plate-type primary air filter. Extension plates are symmetrically welded to the left and right ends of the dust removal chamber, and a threaded positioning rod engages in the middle of the extension plate. This design solves the problems of poor dust removal efficiency and inconvenience in moving existing fertilizer processing dust removal equipment. This patent has a reasonable structure, multi-stage filtration capabilities, good dust removal effect, and is easy to move and use, with a wide range of applications. However, the above patent still has the following shortcomings: Although the dust can be filtered by multiple filters in the multi-stage filtration assembly, the filters are easily clogged when the amount of dust is large, and manual cleaning of the dust attached to the filters is required, which is not very convenient. In addition, the height of the equipment is fixed, which is not convenient for handling the dust in the workshop at different heights, and it will affect the workshop environment. Therefore, we have proposed a fertilizer dust removal equipment. Utility Model Content

[0030] For details, please refer to Figure 2 and Figure 6 The support mechanism 2 includes two support seats 18 fixedly connected to the top surface of the base 1. A bidirectional lead screw 19 is rotatably connected between the two support seats 18. Movable blocks 20 are threaded onto the outer sides of both ends of the bidirectional lead screw 19.

[0031] In this embodiment, the movable block 20 is limited by the movable cooperation between the limiting rod 22 and the movable block 20, so that the movable block 20 can only move along the axial direction of the bidirectional lead screw 19. In addition, the bottom surface of the movable block 20 and the top surface of the base 1 are in contact to ensure the stability of the movable block 20 and the support frame 21 in supporting the dust collector 3.

[0032] For details, please refer to Figures 1 to 3 An elastic annular cloth 25 is fixedly connected to the top surface of the base 1. The top end of the elastic annular cloth 25 is connected to the bottom surface of the dust collection box 3. The elastic annular cloth 25 is located on the outside of the support mechanism 2. Multiple self-locking casters 24 are fixedly installed on the bottom surface of the base 1.

[0033] In this embodiment, the outer side of the support mechanism 2 is protected by an elastic annular cloth 25, and the device can be moved by the self-locking casters 24. At the same time, the self-locking function of the self-locking casters 24 can fix the dust removal device in a certain position.

[0034] For details, please refer to Figure 1 , Figure 2 and Figure 4 The dust collector 3 has slides 26 fixedly connected to both ends, and multiple slide rods 27 fixedly connected to the top surface of the base 1. The slide rods 27 and slides 26 are movably connected.

[0035] In this embodiment, the sliding block 26 and the sliding rod 27 are used to limit the movement between the base 1 and the dust collection box 3, ensuring that the dust collection box 3 can only move up and down, while ensuring the stability of the dust collection box 3.

[0036] For details, please refer to Figures 1 to 3 The top surface of the dust collector 3 has multiple screw holes 29, and the top surface of the cover 12 has multiple stepped holes 28. Bolts 30 are fitted into the inner cavity of the stepped holes 28, and the bottom end of the bolts 30 is threaded into the inner cavity of the screw holes 29. A handle 31 is fixedly installed on the top surface of the cover 12.

[0037] In this embodiment, the cover 12 is installed on the top of the dust collector 3 by means of the screw hole 29, the stepped hole 28 and the bolt 30. The cover 12 is taken out by the handle 31. The pull-out groove 5 can be replaced and cleaned by removing the cover 12.

[0038] For details, please refer to Figure 5 The side of the movable seat 15 fits against the inner wall of the movable groove 13.

[0039] In this embodiment, the inner wall of the moving groove 13 is used to limit the moving seat 15, so that the moving seat 15 and the E-shaped scraper 16 can only move along the axial direction of the reciprocating screw 14.

[0040] For details, please refer to Figures 1 to 3The filter surface of the filter screen 6 is in contact with the inner wall of one side of the pull-out groove 5, and the side of the collection box 7 is in contact with the inner wall of the pull-out groove 5.

[0041] In this embodiment, the dust filtered down from the filter screen 6 is ensured to fall smoothly into the collection box 7.

[0042] Working Principle: In operation, the axial flow fan 11 is first activated, generating suction in the dust collection groove 8 at one end of the dust collector 3's inner cavity. This suction forces dust from the fertilizer production workshop through the stainless steel inlet mesh 9 into the inner cavity of the dust collector 3. Multiple filter screens 6 within the dust collector 3's inner cavity then filter the airborne dust in stages. The filtered air is discharged from the guide hood 10. Next, multiple first motors 17 are activated, driving multiple reciprocating screws 14 to rotate. The threaded connection between the reciprocating screws 14 and the moving seat 15 causes the moving seat 15 to reciprocate along the axial direction of the reciprocating screws 14. The moving seat 15 then drives the E-shaped scraper 16 to scrape the dust from the filter surfaces of the multiple filter screens 6, causing the dust to escape from the filter. The dust falls downwards into the groove on the E-shaped scraper 16, collecting it into the collection box 7 and ensuring the filtration effect of the filter screen 6. Then, the second motor 23 is started to drive the bidirectional lead screw 19 to rotate. Through the threaded transmission between the bidirectional lead screw 19 and the two moving blocks 20, the two moving blocks 20 move closer or further apart, thereby using the support frame 21 to move the dust collector 3 up or down, thus removing dust from areas at different heights. Finally, when not removing dust, the collection box 7 can be pulled out from the pull-out slot 5 by holding the handle 32 to clean the dust collected in the collection box 7. In addition, the cover 12 can be removed to take out the multiple filter screens 6 in the dust collector 3 for replacement or cleaning.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
