Description

Technical Field

[0001] This application belongs to the field of humic acid fertilizer production technology, specifically a humic acid fertilizer pretreatment device. Background Technology

[0002] Humic acid mainly originates from raw materials such as lignite and weathered coal. These raw materials need to be crushed to below 80-100 mesh to ensure the efficiency and product quality of subsequent extraction processes. Pretreatment devices process the raw materials into uniform fine powder through crushing and mixing functions, facilitating the release and utilization of humic acid. Traditional pretreatment devices mostly employ mechanical crushing methods, using blades and screen structures to cut the raw materials into tiny particles. For example, some devices use a motor-driven rotating shaft and multiple sets of blades to achieve efficient crushing and filtration, ensuring that the material particle size meets requirements. Through efficient crushing and uniform mixing, high-quality raw materials are provided for subsequent humic acid extraction and fertilizer preparation.

[0003] However, the coarse particles after crushing and screening in common humic acid fertilizer pretreatment devices need to be crushed again manually, which is costly. In addition, the filter screen is easily clogged during the screening process, which is inconvenient to replace and clean, resulting in low screening efficiency. Utility Model Content

[0004] The purpose of this application is to provide a humic acid fertilizer pretreatment device in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: A humic acid fertilizer pretreatment device includes a pretreatment unit, which includes a crushing layer, a filtering and screening layer, and a mixing layer. The crushing layer includes a crushing motor, a feed inlet, an eccentric elliptical connecting shaft, and a main crushing roller. The filtering and screening layer includes a screening fixed shell, a transmission rod, a screening fixed shell connecting shaft, a screening screen mounting groove, a screening screen, a pulley, and a secondary crushing roller. The mixing layer includes a mixing tank, a mixing motor, a mixing rod, a fixed discharge port, a rotating discharge port, and a rotating discharge port handle.

[0006] By adopting the above technical solution, during the operation of the equipment, humic acid fertilizer is added through the feed inlet. The crushing motor is started, and the main crushing roller is rotated through the eccentric elliptical connecting shaft to crush the humic acid fertilizer. The crushed material falls onto the screen. The rotation of the eccentric elliptical connecting shaft also drives the transmission rod, which in turn moves the screen fixing shell up and down, allowing the humic acid fertilizer falling onto the screen to be screened. Fine particles fall through the screen into the mixing layer, while coarse particles slide down the screen to the top of the auxiliary crushing roller for further crushing. The crushed humic acid fertilizer slides into the mixing layer through the partition. The operation of this equipment can completely crush the humic acid fertilizer, improving the crushing efficiency.

[0007] The bottom of the screening housing has a screening screen installation groove. When the filter holes of the screening screen are blocked, the screening screen can be pulled out from the screening screen installation groove for replacement or cleaning, ensuring filtration efficiency and facilitating the replacement and cleaning of the screening screen.

[0008] In a preferred embodiment, a crushing motor is fixedly connected to the outer side of the crushing layer, an eccentric elliptical connecting shaft is rotatably connected to the back side of the crushing motor, and a main crushing roller is fixedly connected to the back side of the eccentric elliptical connecting shaft.

[0011] By adopting the above technical solution, the rotation of the eccentric elliptical connecting shaft can drive the transmission rod to vibrate up and down, thereby causing the screening screen inside the screening fixed shell to vibrate, thus screening humic acid fertilizer.

[0012] In a preferred embodiment, a screening mesh mounting groove is provided at the bottom of the screening fixing shell, and a screening mesh is slidably connected to the inner side of the screening mesh mounting groove.

[0013] By adopting the above technical solution, the screening screen can be easily installed, replaced, and cleaned through the screening screen installation groove, preventing the screening screen from clogging and causing low equipment operating efficiency.

[0014] In a preferred embodiment, a belt is rotatably connected to the front of the crushing motor, a pulley is slidably connected to the other end of the belt, and an auxiliary crushing roller is fixedly connected to the back of the pulley.

[0015] By adopting the above technical solution, the crushing motor drives the belt and pulley, which in turn drives the auxiliary crushing roller to rotate, thereby crushing the coarse particles after screening.

[0016] In a preferred embodiment, a mixing tank is provided on the inner side of the mixing layer, a mixing motor is fixedly connected to the upper part of the mixing tank, a mixing motor shaft is rotatably connected to the bottom of the mixing motor, and a mixing rod is fixedly connected to the outer side of the mixing motor shaft.

[0017] By adopting the above technical solution, the crushed humic acid fertilizer that falls into the mixing tank can be stirred and mixed.

[0018] In a preferred embodiment, a fixed discharge port is fixedly connected to the bottom of the mixing tank, a rotating discharge port is rotatably connected below the fixed discharge port, and a rotating discharge port handle is fixedly connected to the outside of the rotating discharge port.

[0019] By adopting the above technical solution, the discharge port can be rotated by turning the discharge port handle, thereby releasing the evenly mixed humic acid fertilizer.

[0020] In a preferred embodiment, a feed inlet is fixedly connected above the crushing layer.

[0021] By adopting the above technical solution, it is convenient to put in the humic acid fertilizer to be treated.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: During operation, humic acid fertilizer is added through the feed inlet. The crushing motor is started, driving the main crushing roller to rotate via the eccentric elliptical connecting shaft, which crushes the humic acid fertilizer. The crushed material falls onto the screen. The rotation of the eccentric elliptical connecting shaft also drives the transmission rod, which in turn moves the screen housing up and down, allowing the humic acid fertilizer falling onto the screen to be screened. Fine particles fall through the screen into the mixing layer, while coarse particles slide down the screen to the top of the auxiliary crushing roller for further crushing. The crushed humic acid fertilizer then slides into the mixing layer through the partition. Through the operation of this equipment, the humic acid fertilizer can be completely crushed, improving the crushing efficiency.

[0023] The bottom of the screening housing has a screening screen installation groove. When the filter holes of the screening screen are blocked, the screening screen can be pulled out from the screening screen installation groove for replacement or cleaning, ensuring filtration efficiency and facilitating the replacement and cleaning of the screening screen.

The mixing layer 3 includes a mixing tank 17, a mixing motor 18, a mixing rod 20, a fixed discharge port 21, a rotating discharge port 22, and a rotating discharge port handle 23.

[0028] During operation, humic acid fertilizer is added through the feed inlet 12. The crushing motor 4 is started, which drives the main crushing roller 6 to rotate via the eccentric elliptical connecting shaft 5, thus crushing the humic acid fertilizer. The crushed material falls onto the screen 11. The rotation of the eccentric elliptical connecting shaft 5 also drives the transmission rod 9, which in turn moves the screening fixed shell 8 up and down, allowing the humic acid fertilizer falling onto the screen 11 to be screened. Fine particles fall through the screen 11 into the mixing layer 3, while coarse particles slide down the screen 11 to the top of the auxiliary crushing roller 15 for further crushing. The crushed humic acid fertilizer slides into the mixing layer 3 through the partition 16. The operation of this equipment can completely crush the humic acid fertilizer, improving the crushing efficiency.

[0029] The bottom of the screening fixed shell 8 is provided with a screening screen installation groove 10. When the filter holes of the screening screen 11 are blocked, the screening screen 11 can be pulled out from the screening screen installation groove 10 for replacement or cleaning, so as to ensure the filtration efficiency and facilitate the replacement and cleaning of the screening screen 11.

[0030] A crushing motor 4 is fixedly connected to the outer side of the crushing layer 1. An eccentric elliptical connecting shaft 5 is rotatably connected to the back side of the crushing motor 4. A main crushing roller 6 is fixedly connected to the back side of the eccentric elliptical connecting shaft 5. By starting the crushing motor 4, the eccentric elliptical connecting shaft 5 and the main crushing roller 6 can be rotated, thereby enabling crushing.

[0031] A screening fixing shell connecting shaft 7 is rotatably connected to the inner side of the filter screen layer 2. A screening fixing shell 8 is fixedly connected to the inner side of the screening fixing shell connecting shaft 7. A transmission rod 9 is rotatably connected to the side of the screening fixing shell 8. An eccentric elliptical connecting shaft 5 is rotatably connected above the transmission rod 9. The rotation of the eccentric elliptical connecting shaft 5 can drive the transmission rod 9 to vibrate up and down, thereby causing the screening screen 11 inside the screening fixing shell 8 to vibrate, thus screening the humic acid fertilizer.

[0032] The bottom of the screening housing 8 is provided with a screening screen mounting groove 10, and a screening screen 11 is slidably connected to the inner side of the screening screen mounting groove 10. The screening screen 11 can be easily installed, replaced and cleaned through the screening screen mounting groove 10, preventing the screening screen 11 from becoming clogged and causing low equipment operating efficiency.

[0033] A belt 13 is rotatably connected to the front of the crushing motor 4, and a pulley 14 is slidably connected to the other end of the belt 13. A secondary crushing roller 15 is fixedly connected to the back of the pulley 14. By driving the belt 13 and pulley 14, the crushing motor 4 can drive the secondary crushing roller 15 to rotate, thereby further crushing the coarse particles after screening.

[0034] A mixing tank 17 is provided on the inner side of the mixing layer 3. A mixing motor 18 is fixedly connected to the top of the mixing tank 17. A mixing motor shaft 19 is rotatably connected to the bottom of the mixing motor 18. A mixing rod 20 is fixedly connected to the outer side of the mixing motor shaft 19.

[0036] A feed inlet 12 is fixedly connected above the crushing layer 1 to facilitate the feeding of humic acid fertilizer to be processed.

[0037] The implementation principle of the humic acid fertilizer pretreatment device embodiment of this application is as follows: During the operation of the equipment, humic acid fertilizer is added through the feed inlet 12. The crushing motor 4 is started, which drives the main crushing roller 6 to rotate through the eccentric elliptical connecting shaft 5, thereby crushing the humic acid fertilizer. The crushed material falls onto the screen 11. The rotation of the eccentric elliptical connecting shaft 5 also drives the transmission rod 9, which in turn drives the screening fixed shell 8 to move up and down, thus screening the humic acid fertilizer falling onto the screen 11 and separating the fine particles. The particles fall into the mixing layer 3 through the screening screen 11. The coarse particles will slide down the screening screen 11 to the top of the secondary crushing roller 15 for further crushing. The crushed humic acid fertilizer slides into the mixing layer 3 through the partition plate 16. The mixing motor 18 drives the mixing motor shaft 19 and the mixing rod 20 to rotate, which can mix the crushed humic acid fertilizer evenly. Then, rotate the discharge port handle 23 to align the holes on the fixed discharge port 21 and the rotating discharge port 22 to release the pretreated humic acid fertilizer.
