Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer technology, and in particular to an organic fertilizer raw material pretreatment device with a dust treatment structure. Background Technology

[0002] Organic fertilizers are fertilizers made primarily from plant and animal remains or metabolic products, processed through biological fermentation or natural decomposition, and containing abundant organic matter and various nutrients. Common organic fertilizers include compost, farmyard manure, green manure, well-rotted human and animal excrement, oilseed cake, and bone meal. They not only provide crops with essential nutrients such as nitrogen, phosphorus, and potassium, but also improve soil structure, increase soil organic matter content, enhance soil microbial activity, and improve soil fertility. Compared to chemical fertilizers, organic fertilizers are more environmentally friendly and contribute to the sustainable development of agriculture.

[0003] Before processing organic fertilizers, the crushed compost, farmyard manure, green manure, well-rotted human and animal excrement, oilseed cake, and bone meal must be finely filtered and screened to eliminate agglomerates and lumps, ensuring uniform mixing in the subsequent process. However, existing raw material pretreatment equipment generally relies solely on static screening screens, lacking mechanical actuation mechanisms and spring amplification devices. This makes it impossible to efficiently vibrate and screen raw materials of different particle sizes, and it is also difficult to promptly separate and guide residual lumps out. Furthermore, traditional screening processes lack effective dust collection or suppression structures, leading to significant dust emissions that not only affect the cleanliness of the production environment but also pose a potential health hazard to operators. Therefore, their use has certain limitations.

[0004] Therefore, there is an urgent need for a pretreatment device that integrates vibrating screening and dust treatment to improve screening efficiency, eliminate agglomeration, and achieve environmental safety. Based on this, we propose an organic fertilizer raw material pretreatment device with a dust treatment structure. Utility Model Content

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.

[0019] Example: Refer to Figures 1 to 7 This utility model provides an embodiment of an organic fertilizer raw material pretreatment device with a dust treatment structure, including a raw material screening frame 1. A feeding dust suppression component 2 is installed on the top of the raw material screening frame 1. First discharge hoppers 3 are connected to both sides of the raw material screening frame 1, and a second discharge hopper 4 is provided at the bottom of the raw material screening frame 1. A raw material screening component 5 is also provided inside the raw material screening frame 1. The raw material screening component 5 includes a frame plate 6, screening filters 7 are provided on both sides of the frame plate 6, and two sets of guide slide plates 8 are installed at both ends of the frame plate 6. The two ends of the guide slide plates 8 are respectively connected to... The first compression spring 9, through the cooperation of the raw material screening component 5, drive motor 11, and actuating wheel 12, can separate raw materials of different particle sizes. Qualified organic fertilizer raw material particles can be discharged outward through the second hopper 4 installed at the bottom of the raw material screening frame 1, while unqualified organic fertilizer raw material particles can be discharged outward through the first hopper 3 installed on both sides of the raw material screening frame 1. This can solve the problems of low screening efficiency and inability to effectively separate clumps in existing equipment, and can achieve efficient screening of organic fertilizer raw materials to ensure uniform mixing and stirring in the subsequent process.

[0020] Two sets of guide grooves 10 are provided on both sides of the raw material screening frame 1. The guide grooves 10 are structurally matched with the guide slide plate 8, and the guide grooves 10 and the guide slide plate 8 are in sliding fit. Drive motors 11 are installed in the middle of both sides of the raw material screening frame 1 near the guide grooves 10. The output ends of the two sets of drive motors 11 are respectively connected to actuating wheels 12. The actuating wheels 12 are in rolling contact with the frame plate 6. The outer sides of the two sets of actuating wheels 12 are respectively provided with guide hoods 13. Annular slots 14 are also provided around the top of the raw material screening frame 1. Through the structural design of the rolling contact between the actuating wheels 12 and the frame plate 6, the rotational motion of the drive motors 11 can be efficiently converted into raw material rotation. The vibration of the screening component 5 achieves uniform screening of organic fertilizer raw materials, ensuring effective separation of raw material particles of different sizes, improving screening efficiency and quality. The feeding dust suppression component 2 includes a feeding box 15, with annular insert plates 16 installed around the bottom of the feeding box 15. The annular insert plates 16 and annular slots 14 are structurally matched and interlocked. Positioning slots 17 are provided on both sides of the feeding dust suppression component 2. Dust filters 18 are also provided inside the two sets of positioning slots 17. Through the interlocking structure between the annular insert plates 16 and the annular slots 14, the feeding box 15 for dust prevention can be assembled on the top of the raw material screening frame 1.

[0021] Both sides of the opening of the feed box 15 are hinged with baffles 19. Spring telescopic rods 20 are connected between the two sets of baffles 19 and the inner side of the feed box 15. These spring telescopic rods 20 allow for flexible opening and closing of the feed channel, achieving initial interception of dust during raw material feeding and reducing dust emission at the moment of material input. Simultaneously, they provide balanced elastic support when opening and closing the baffles 19, achieving self-weight balance and buffered closure, ensuring controllable feed opening and smooth operation. Dust-suppressing connecting covers 21 are also provided on both sides of the feed box 15. Extraction pipe heads 22 are installed on the outer sides of the two sets of dust-suppressing connecting covers 21, with a through connection between the extraction pipe head 22 and the dust-suppressing connecting cover 21. Dust-reducing connecting covers 21 are provided on both sides of the feed box 15, and an exhaust pipe head 22 is provided on the outside to connect through to them, which can form a dust extraction channel. When the raw material generates dust in the feed box 15, the dust is discharged through the exhaust pipe head 22 and the dust-reducing connecting cover 21 by the negative pressure dust removal equipment, so as to realize the immediate collection and treatment of dust, thereby reducing dust emission, reducing the harm to the health of operators, and maintaining a clean working environment. The dust-reducing connecting cover 21 is structurally matched with the positioning groove 17. The dust-reducing connecting cover 21 and the positioning groove 17 are in a snap-fit ​​fit. Through the snap-fit ​​fit structure between the dust-reducing connecting cover 21 and the positioning groove 17, the limit can be snapped on both sides of the outside of the feed box 15. The feed box 15 can also be disassembled, connected, repaired and replaced according to the usage.

[0022] Working Principle: The raw material pretreatment equipment designed in this scheme introduces the crushed organic fertilizer raw material through the feeding and dust suppression component 2 at the top of the raw material screening frame 1. The raw material falls onto the screening filter screen 7 of the raw material screening component 5. Then, the drive motor 11 installed in the middle of both sides of the raw material screening frame 1 drives the actuating wheel 12 to rotate. Since the actuating wheel 12 has rolling contact with the frame plate 6 and the guide slide 10 has sliding contact with the guide slide plate 8, it can push the raw material screening component 5 to vibrate up and down inside the raw material screening frame 1. The first compression springs installed at both ends of the guide slide plate 8 can also be used to control the vibration. 9. It can also act as a buffer and vibration amplification mechanism, effectively enhancing the screening effect of the raw material screening component 5 on the vibration of organic fertilizer raw materials. Finally, the screening filter screen 7 separates raw materials of different particle sizes. Qualified organic fertilizer raw material particles can be discharged outward through the second row hopper 4 installed at the bottom of the raw material screening frame 1, while unqualified organic fertilizer raw material particles can be discharged outward through the first row hopper 3 installed on both sides of the raw material screening frame 1. This can solve the problems of low screening efficiency and inability to effectively separate agglomerates in existing equipment, and can achieve efficient screening of organic fertilizer raw materials, ensuring uniform mixing and stirring in the subsequent process.

[0023] The raw material pretreatment equipment designed in this scheme uses hinged covers 19 on both sides of the opening of the feed box 15. Under the action of the spring telescopic rod 20, the two sets of covers 19 can be reset, which can immediately seal off the dust generated by the organic fertilizer raw materials fed into the feed box 15, reducing dust dispersion. Then, through the dust-suppressing connecting covers 21 on both sides of the feed box 15 and the externally installed exhaust pipe head 22, the exhaust pipe of the dust removal equipment can be connected to both sides of the feed box 15. The dust generated by the feeding can be treated by the dust-suppressing connecting covers 21, which can solve the problem of serious dust pollution in the traditional screening process, achieve effective dust suppression and collection, improve the production environment, and protect the health of operators.

[0024] 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.
