Description

Technical Field

[0001] This utility model relates to the field of soil removal technology for biochar-based fertilizer raw materials, and in particular to a biochar-based fertilizer raw material soil removal device. Background Technology

[0002] Biochar-based fertilizer is an environmentally friendly fertilizer made primarily from biochar and combined with organic or inorganic nutrients. The raw materials for biochar-based fertilizer often contain a lot of soil, so it is necessary to remove the soil from the raw materials to ensure the quality of the fertilizer.

[0003] A search of Chinese Patent Publication No. CN220329185U reveals a device for removing soil from carbon-based fertilizer raw materials. This device includes several concentrically arranged limiting rings mounted on a frame. A screen cylinder is horizontally arranged within the limiting rings, with helical blades installed inside the screen cylinder and a mesh screen mounted on it. Two rolling wheels are rotatably connected within the limiting rings, and these rolling wheels are driven by a motor via a transmission shaft. The rolling wheels make rolling contact with the screen cylinder. An elastic pressing wheel assembly is installed at the top of the limiting rings. The advantages of this invention are: by designing the inclined screen cylinder as a horizontal one, the friction between the rolling wheels and the limiting rings is reduced, increasing the service life of the rolling wheels. The elastic pressing wheel assembly applies radial elastic force to the screen cylinder, preventing excessive slippage between the rolling wheels and the screen cylinder, improving the transmission efficiency of the screen cylinder. Simultaneously, it effectively prevents large radial runout of the screen cylinder, ensuring safe and efficient production. This invention is worthy of widespread application.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned soil removal device: the two ends of the screen cylinder in the existing technology are open, and the screen cylinder is always horizontal, which makes it easy for the raw material to flow directly out from both ends of the screen cylinder, affecting the screening effect. In addition, the spiral blades in the existing technology are directly fixed on the screen cylinder. However, in actual operation, the spiral blades can only effectively drive the raw material inside the screen cylinder to move when they rotate relative to the screen cylinder. Therefore, the existing technology not only cannot stably drive the raw material to move, but the raw material also easily flows out from both ends of the screen cylinder, affecting the screening effect. Based on this, this utility model designs a soil removal device for biochar-based fertilizer raw materials to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a soil removal device for biochar-based fertilizer raw materials, so as to solve the problem mentioned in the background art that the existing technology cannot stably and effectively remove soil from biochar-based fertilizers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biochar-based fertilizer raw material soil removal device, comprising a fixed base plate and a middle support ring, wherein screening cylinders are respectively installed at both ends of the middle support ring, and a support ring seat is installed at one end of the screening cylinder; A fixing frame is installed on the top outer wall of the fixed base plate, and a retaining ring is installed on each of the two side walls of the fixing frame.

A retaining ring is slidably engaged on the intermediate support ring, and a limiting ring is installed at one end of the retaining ring. A fixing ring is installed on the side wall of the intermediate support ring, and an adjusting bolt for connecting the fixing ring and the limiting ring is connected to the fixing ring.

[0007] As a preferred embodiment, the screening cylinder is provided with a feed inlet, a feed pipe is installed on the feed inlet, and a protective cover is connected to the threaded outer surface of the feed pipe.

[0008] As a preferred embodiment, limit frames are respectively installed on the two outer walls of the fixed base plate, a fixing sleeve is installed on one side wall of the limit frame, a plane bearing is provided inside the fixing sleeve, and a positioning block is installed on one side wall of the support ring seat.

[0009] As a preferred embodiment, a positioning shaft is installed on one side wall of the fixing ring, and the limiting ring is engaged with the positioning shaft.

[0010] As a preferred embodiment, a drive wheel for rotating the support ring seat is rotatably connected to the retaining ring. A driven pulley is installed at one end of the drive wheel. Support side plates are respectively installed on the bottom outer wall of the fixed base plate. A drive shaft is rotatably connected to the support side plate. A drive pulley is respectively installed on the side wall of the drive shaft. The drive pulley is connected to the driven pulley through a transmission belt.

[0011] As a preferred embodiment, a drive motor is installed on the bottom outer wall of the fixed base plate, a drive gear is connected to the output end of the drive motor, and a driven gear is installed on the side wall of the drive shaft, the driven gear meshing with the drive gear.

[0012] As a preferred embodiment, baffles are installed on both sides of the fixing frame.

[0013] The technical effects and advantages of this utility model are as follows: By pouring the raw material into the screening cylinder and then rotating the screening cylinder, the soil in the raw material can be screened out.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] This utility model provides, for example Figure 1-6The illustrated biochar-based fertilizer raw material desoiling device includes a fixed base plate 1 and a central support ring 3. The central support ring 3 has multiple slots. Screening cylinders 4 are installed at both ends of the central support ring 3. The screening cylinders 4 have a conical structure and multiple reinforcing ribs. A support ring seat 6 is installed at one end of the screening cylinder 4. A fixing frame 2 is installed on the top outer wall of the fixed base plate 1. Retaining rings 5 ​​are installed on both side walls of the fixing frame 2. Auxiliary support wheels 9 for supporting the support ring seat 6 are rotatably connected to the retaining rings 5. Multiple auxiliary support wheels 9 are in contact with the side walls of the support ring seat 6. A retaining ring 10 is slidably engaged on the central support ring 3. Screening holes are provided on both the screening cylinders 4 and the retaining ring 10. A limit ring 11 is installed at one end of the retaining ring 10. A fixing ring 12 is installed on the side wall of the central support ring 3. A device for securing the fixing ring 12 is connected to the fixing ring 12. The adjusting bolt 13 connected to the limiting ring 11 has a feed inlet on the screening cylinder 4. A feed pipe 24 is installed on the feed inlet. The side wall of the feed pipe 24 is threaded. A protective cover 25 is connected to the thread on the outer surface of the feed pipe 24. When using this device, the raw material is first poured into the inside of the screening cylinder 4. Then, by driving the screening cylinder 4 to rotate, the mud in the raw material can be screened out. After screening, the adjusting bolt 13 is loosened first, and then the retaining ring 10 is pulled so that the retaining ring 10 no longer blocks the groove on the intermediate support ring 3. Since the screening cylinder 4 is conical, the raw material inside it will move towards the intermediate support ring 3, so that the raw material can be discharged from the groove on the intermediate support ring 3. Therefore, this device can ensure that the raw material is always inside the screening cylinder 4 during the screening process, and the raw material inside the screening cylinder 4 can be discharged conveniently and stably during subsequent unloading.

[0023] In this embodiment, as Figure 2 As shown, limit frames 7 are installed on the two outer walls of the fixed base plate 1 respectively. A fixed sleeve 8 is installed on one side wall of the limit frame 7. A plane bearing 15 is installed inside the fixed sleeve 8. The plane bearing 15 is a standard part, which is a bearing used to bear axial (thrust) load or low-speed rotational motion. A positioning block 14 is installed on one side wall of the support ring seat 6. The positioning block 14 is located inside the fixed sleeve 8, and the diameter of the positioning block 14 is smaller than the inner diameter of the fixed sleeve 8. One end of the positioning block 14 abuts against the plane bearing 15 inside the fixed sleeve 8, thereby limiting the support ring seat 6, and further limiting the intermediate support ring 3 and the screening cylinder 4 to prevent them from moving left and right.

[0024] In this embodiment, as Figure 5 As shown, a positioning shaft 17 is installed on one side wall of the fixed ring 12, and the limiting ring 11 is engaged with the positioning shaft 17. By engaging the limiting ring 11 with the positioning shaft 17 on the fixed ring 12, the limiting ring 11 can be limited, which helps to improve the stability of the limiting ring 11 when it is fixed.

[0025] In this embodiment, as Figure 1 As shown, a drive wheel 16 for rotating the support ring seat 6 is rotatably connected to the retaining ring 5. A driven pulley 18 is installed at one end of the drive wheel 16. Support side plates 20 are respectively installed on the bottom outer wall of the fixed base plate 1. A drive shaft 21 is rotatably connected to the support side plate 20. A drive pulley 22 is respectively installed on the side wall of the drive shaft 21. The drive pulley 22 is connected to the driven pulley 18 through a transmission belt. A drive motor 23 is installed on the bottom outer wall of the fixed base plate 1. The output end of the drive motor 23 is connected to the main... The driven gear 27 is installed on the side wall of the drive shaft 21 and is connected to the driving gear 26. The driving gear 27 meshes with the driving gear 26. The driving motor 23 drives the driving gear 26 at its output end to rotate, so that the drive shaft 21 can drive the driving pulley 22 to rotate. The driving pulley 22 can drive the driven pulley 18 to rotate, which in turn drives the drive wheel 16 to rotate. Under the action of friction, the drive wheel 16 can drive the support ring seat 6 to rotate, which in turn drives the screening cylinder 4 to rotate.

[0026] In this embodiment, as Figure 4 As shown, baffles 19 are installed on both sides of the fixed frame 2. During screening, the baffles 19 can block the sides of the screening cylinder 4 to prevent soil from being thrown out from the sides of the screening cylinder 4.

[0027] Working principle of this utility model: This utility model is a soil removal device for biochar-based fertilizer raw materials. By pouring the raw materials into the inside of the screening cylinder 4, and then driving the screening cylinder 4 to rotate, the soil in the raw materials can be screened out. After screening, loosen the adjusting bolt 13 and pull the retaining ring 10 so that it no longer blocks the slot on the intermediate support ring 3. Since the screening cylinder 4 is conical, the raw material inside it will move towards the intermediate support ring 3, so that the raw material can be discharged from the slot on the intermediate support ring 3. Therefore, the device can ensure that the raw material is always inside the screening cylinder 4 when screening the raw material, and can also easily and stably discharge the raw material inside the screening cylinder 4 during subsequent unloading.

[0028] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
