[0001] This utility model belongs to the field of fertilizer production technology, specifically a filtration device for fertilizer production. Background Technology
[0002] Fertilizers are substances that directly or indirectly supply nutrients to crops in agricultural production, thereby increasing crop yields.
[0003] In the fertilizer production process, it is necessary to first select raw materials, then crush, mix and screen the suitable raw materials to obtain raw materials that meet the requirements of subsequent production processes. Then, the raw materials are converted into the required fertilizer components through chemical reactions. The fertilizer is then granulated or shaped to obtain the appropriate shape and size. Finally, the shaped fertilizer is dried, cooled and screened to improve the quality of the fertilizer.
[0004] During the screening and filtration process of fertilizer production, finer fertilizer particles fall through the screen to the bottom. The fertilizer particles remaining on the screen are usually larger in size. After a long period of filtration, the accumulated large fertilizer particles can easily cause the screen to become clogged, affecting subsequent screening and filtration.

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a filtration device for fertilizer production includes a screening and filtration box 1; a feed inlet 2 is provided at the top of the screening and filtration box 1; a discharge box 3 is slidably connected to the bottom of the screening and filtration box 1; a screen plate 4 is provided inside the screening and filtration box 1; the screen plate 4 is inclined; a second movable groove 8 is provided on the side wall of the screening and filtration box 1; a storage box 5 is fixedly connected to the outer side wall of the screening and filtration box 1; the storage box 5 is sleeved on the second movable groove 8; the bottom end of the screen plate 4 is located inside the second movable groove 8. During operation, fertilizer that needs to be screened and filtered is fed into the feed inlet 2. Upon entering the screening and filtration box 1, the fertilizer falls onto the surface of the screen plate 4. After being screened and filtered by the screen plate 4, small fertilizer particles fall into the discharge box 3 below for collection, while large fertilizer particles slide towards the storage box 5 due to the inclined screen plate 4. Finally, after passing through the second movable trough 8, they fall into the storage box 5. By setting the inclined screen plate 4, large fertilizer particles after screening and filtration can be recovered, while reducing fertilizer accumulation on the surface of the screen plate 4, improving the screening and filtration effect, reducing the problem of the screen plate 4 being blocked and unable to perform effective filtration, and improving the stability of the screening and filtration process.
[0025] like Figures 1 to 5As shown, the screening and filtering box 1 has a first movable groove 7 on its side wall; a connecting plate 6 is fixedly connected to the top of the screen plate 4; the connecting plate 6 is located inside the first movable groove 7; a drive motor 9 is fixedly connected to the outer wall of the screening and filtering box 1; the drive motor 9 is located below the first movable groove 7; a reciprocating screw 10 is fixedly connected to the output end of the drive motor 9; the reciprocating screw 10 passes through the side wall of the connecting plate 6 and is threadedly connected to the connecting plate 6; a limit plate 11 is fixedly connected to the end of the reciprocating screw 10. During operation, the screw 10 moves through the screening... During the process, the drive motor 9 is turned on, causing the drive motor 9 to drive the reciprocating screw 10 to rotate. Because the reciprocating screw 10 is provided with reciprocating threads, as the reciprocating screw 10 rotates continuously, the connecting plate 6 continuously drives the screen plate 4 to move back and forth, thereby shaking the fertilizer particles on the surface of the screen plate 4, making it easier for the fertilizer to separate from the screen plate 4, and making the fertilizer fall from the screen plate 4 into the storage box 5 more stably. By making the screen plate 4 vibrate back and forth continuously, the cleaning effect of residual fertilizer on the surface of the screen plate 4 is improved.
[0026] like Figure 4 As shown, elastic cloth 13 is fixedly connected to the top and bottom sidewalls of the connecting plate 6; the end of the elastic cloth 13 is fixedly connected to the inner sidewall of the screening and filtering box 1. During operation, by providing elastic cloth 13 between the connecting plate 6 and the screening and filtering box 1, the elastic cloth 13 can protect the first movable groove 7, reduce the possibility of fertilizer falling to the outside through the first movable groove 7 during the screening and filtering process, improve the protection effect of fertilizer, and reduce waste.
[0027] like Figure 3 As shown, an air pump 14 is fixedly connected to the outer wall of the screening and filtering box 1; an air pipe 15 is fixedly connected to the output end of the air pump 14; the end of the air pipe 15 is fixedly connected to the top side wall of the screening and filtering box 1; multiple nozzles 16 are fixedly connected to the middle of the air pipe 15; the nozzles 16 penetrate the side wall of the screening and filtering box 1 and extend into the interior of the screening and filtering box 1; the nozzles 16 are inclined; a ventilation opening 17 is provided on the side wall of the screening and filtering box 1. During operation, in the process of screening and filtering, by turning on the switch of the air pump 14, the air pump 14 is directed to... Air is supplied inside the air pipe 15. At this time, the airflow is sprayed into the screening and filtering box 1 through the nozzle 16 to dry the fertilizer, reduce the residual moisture on the fertilizer, and thus reduce the problem of fertilizer sticking together and being difficult to separate. This improves the fertilizer screening effect and makes it easier for the fertilizer on the surface of the screen plate 4 to fall into the storage box 5 for collection under the action of the flow. This improves the fertilizer recovery and collection effect. By setting the ventilation port 17, the problem of excessive air pressure inside the screening and filtering box 1 can be reduced, thus improving the protection effect of the screening and filtering box 1.
[0028] like Figure 3As shown, a dustproof net 18 is provided inside the ventilation opening 17; the dustproof net 18 and the ventilation opening 17 are detachably fixed together by bolts. During operation, by providing the dustproof net 18, the problem of external dust and impurities falling into the screening and filtering box 1 through the ventilation opening 17 and contaminating the fertilizer can be reduced, thus improving the protection effect of the fertilizer.
[0029] like Figure 3 As shown, a plurality of buffer springs 12 are fixedly connected to the bottom side wall of the sieve plate 4; the ends of the buffer springs 12 are fixedly connected to the outer side wall of the screening and filtering box 1. During operation, by providing buffer springs 12 on the sieve plate 4, the collision between the sieve plate 4 and the screening and filtering box 1 can be reduced during the reciprocating sliding process of the sieve plate 4, thereby reducing the wear of the sieve plate 4 and improving the service life of the sieve plate 4.
[0030] Working principle: The fertilizer to be screened and filtered is fed into the screening and filtering box 1 through the feed inlet 2. The fertilizer will fall onto the surface of the screen plate 4. After being screened and filtered by the screen plate 4, the small particles of fertilizer fall into the discharge box 3 below for collection, while the large particles of fertilizer will slide towards the storage box 5 due to the inclined screen plate 4. Finally, after passing through the second movable trough 8, they fall into the storage box 5. By setting the screen plate 4, the large particles of fertilizer after screening and filtration can be recovered, while reducing the accumulation of fertilizer on the surface of the screen plate 4, improving the screening and filtration effect, reducing the problem of the screen plate 4 being blocked and unable to filter effectively, and improving the stability of the screening and filtration process.
[0031] By turning on the drive motor 9 during the screening process, the drive motor 9 drives the reciprocating screw 10 to rotate. Because the reciprocating screw 10 is provided with reciprocating threads, the connecting plate 6 continuously drives the screen plate 4 to move back and forth during the continuous rotation of the reciprocating screw 10. This causes the fertilizer particles on the surface of the screen plate 4 to be shaken, making it easier for the fertilizer to separate from the screen plate 4. This makes it easier for the fertilizer to fall from the screen plate 4 into the storage box 5 more stably. By making the screen plate 4 vibrate back and forth continuously, the cleaning effect of residual fertilizer on the surface of the screen plate 4 is improved.
[0032] By providing an elastic cloth 13 between the connecting plate 6 and the screening and filtering box 1, the elastic cloth 13 can protect the first movable trough 7, reducing the possibility of fertilizer falling to the outside through the first movable trough 7 during the screening and filtering process, thus improving the protection effect of fertilizer and reducing waste.
[0033] During the screening and filtration process, by turning on the air pump 14, air is pumped into the air pipe 15. At this time, the airflow is sprayed into the screening and filtration box 1 through the nozzle 16 to dry the fertilizer, reduce the residual moisture on the fertilizer, and thus reduce the problem of fertilizer sticking together and being difficult to separate. This improves the fertilizer screening effect and makes it easier for the fertilizer on the surface of the screen plate 4 to fall into the storage box 5 for collection under the influence of the flow. This improves the fertilizer recovery and collection effect. By setting the ventilation port 17, the problem of excessive air pressure inside the screening and filtration box 1 can be reduced, thus improving the protection effect of the screening and filtration box 1.
[0034] By incorporating a dustproof net 18, the problem of external dust and impurities falling into the screening and filtering box 1 through the ventilation opening 17 and contaminating the fertilizer can be reduced, thus improving the protection effect on the fertilizer.
[0035] By providing a buffer spring 12 on the sieve plate 4, the collision between the sieve plate 4 and the screening and filtering box 1 can be reduced during the reciprocating sliding process of the sieve plate 4, thereby reducing the wear of the sieve plate 4 and improving the service life of the sieve plate 4.
