Description
Technical Field
[0001] The utility model relates to the technical field of chemical fertilizer production, in particular to a dust removal structure for a chemical fertilizer granulator. Background Technique
[0002] Materials continuously roll and extrude in the drum of the chemical fertilizer granulator, and will be extruded through the die holes on the inner wall of the drum to form particles. After drying and cooling the chemical fertilizer particles, screening is required. In the existing chemical fertilizer granulator during screening, since dust is generated during the granulation process, the dust will still adhere to the surface of the chemical fertilizer particles during the screening process. In order to avoid polluting the environment, dust removal operations are required.
[0003] For example, the Chinese patent with the application number CN202020449370.4 discloses a chemical fertilizer granulator, including a box body, in which an extrusion structure, a crushing structure, a circulating screening structure and a dust removal structure are installed; the extrusion structure will extrude the materials into a cake shape, and the cake-shaped materials will then be crushed into chemical fertilizer particles by the crushing structure. The qualified chemical fertilizer particles after being crushed will enter the storage box after being screened by the screening net, and the unqualified chemical fertilizer particles will flow into the collection box through the screening net. The dust removal structure will collect, adsorb and discharge the dust generated during granulation, preventing environmental pollution and also preventing problems that affect the health of workers. However, in actual use, during the screening process of the crushed chemical fertilizer particles through the screening net, only part of the dust on the particle surface can be shaken off, and the entrained dust will still adhere to the surface of some chemical fertilizer particles, resulting in the need to improve the dust removal effect. Summary of the Utility Model
[0004] In view of this, the purpose of the present utility model is to propose a dust removal structure for a chemical fertilizer granulator to solve the technical problem that during the screening process of the crushed chemical fertilizer particles through the screening net in the prior art, only part of the dust on the particle surface can be shaken off, and the entrained dust will still adhere to the surface of some chemical fertilizer particles, resulting in the need to improve the dust removal effect.
[0005] Based on the above purpose, the present utility model provides a dust removal structure for a chemical fertilizer granulator, including a box body and a feed cylinder arranged on the box body.

[0027] In the first aspect of the present utility model, a dust removal structure for a fertilizer granulator is proposed, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5As shown in the figure, it includes a box body 1 and a feeding cylinder 2 arranged on the box body 1. A support frame 3 is fixedly arranged on the box body 1 and the feeding cylinder 2, and the support frame 3 is installed on a fertilizer granulator. A check valve 4 is arranged between the box body 1 and the feeding cylinder 2. The opening of the box body 1 expands downward from top to bottom. The dust removal structure further includes:
[0028] A partition plate 5, the partition plate 5 is obliquely placed in the box body 1, and a T-shaped object passing opening 6 is opened in the middle of the partition plate 5;
[0029] Guide rods 7, there are several guide rods 7 and they are evenly distributed in the T-shaped object passing opening 6. The gap between two adjacent guide rods 7 expands downward from top to bottom;
[0030] A sliding member 8 for disassembling the agglomerated fertilizer particles, the sliding member 8 is slidably arranged on the guide rods 7;
[0031] A driving assembly for driving the sliding member 8 to reciprocate on the guide rods 7;
[0032] A fan 9, the fan 9 is installed at the side end of the box body 1, and the air suction port of the fan 9 is communicated with the inside of the box body 1.
[0033] In this embodiment, the driving assembly includes a cylinder 10, a slider 11 and a slip ring 12. The cylinder 10 is installed on the support frame 3, the slider 11 is installed on the output end of the cylinder 10, and the slip ring 12 is fixedly installed at the lower end of the sliding member 8. The slider 11 is slidably arranged in the slip ring 12.
[0034] In this embodiment, the lower end outlet of the feeding cylinder 2 is placed directly above the T-shaped object passing opening 6, and the lower end outlet of the feeding cylinder 2 corresponds to the upper part of the guide rods 7 in the vertical direction.
[0035] In this embodiment, during use, the fertilizer particle material to be screened is put in through the top inlet of the feeding cylinder 2. The check valve 4 is opened and the cylinder 10 is started. The intake amount of the particle material is controlled by the check valve 4. The particle material falls to the upper part of the gap between the adjacent guide rods 7 below. Since the partition plate 5 is obliquely placed in the box body 1, the particle material will roll downward along the gap between the adjacent guide rods 7, so that each entering particle material can roll downward along the gap between the adjacent guide rods 7. This rolling process can effectively remove the dust attached to the surface of each particle material. At the same time, driven by the output end of the cylinder 10, the sliding member 8 is driven to reciprocate on the guide rods 7 through the slider 11 and the slip ring 12, avoiding the accumulation of particle materials on the partition plate 5 and further ensuring the comprehensiveness of dust removal. Finally, the removed dust is sucked out by the fan 9. When the particle material rolls to a gap larger than its diameter, the particle material will automatically fall.
[0036] In this embodiment, as Figure 4 、 Figure 5As shown, the side ends of the sliding member 8 are evenly provided with material pushing heads 13. The material pushing heads 13 are placed in the gaps between adjacent guide rods 7. The material pushing heads 13 will reciprocate synchronously with the sliding member 8 to remove the particulate materials that may be stuck in the gaps between adjacent guide rods 7, ensuring the continuous progress of the screening operation.
[0037] In this embodiment, as Figure 3 、 Figure 5 shown, the upper end of the sliding member 8 is provided with a pressing surface 14. The pressing surface 14 cooperates with one side of the partition plate 5. The upper end of the sliding member 8 is also provided with a reinforcing rib 15. When encountering the situation where fat particles are held together, since the volume of the held materials is large and cannot be discharged from the gap between adjacent guide rods 7, as the sliding member 8 reciprocates on the guide rods 7, the pressing surface 14 and one side of the partition plate 5 can squeeze and split the held fat particles. The reinforcing rib 15 can ensure the self-strength of the sliding member 8 during the squeezing and splitting process, and then continue the screening and dust removal and discharge to the next packaging process.
[0038] In addition, preferably, as Figure 1 、 Figure 2 shown, a dust collection hood 16 is installed at the side end of the box body 1. The exhaust port of the fan 9 is communicated with the inside of the dust collection hood 16. The dust sucked out by the fan 9 will be collected in the dust collection hood 16. After the screening process is completed, the dust in the dust collection hood 16 is cleaned to ensure the working environment of the fertilizer granulator.
