Description
Technical Field
[0001] This utility model relates to the field of organic fertilizer production technology, specifically to a device for producing organic fertilizer using distiller's grains waste. Background Technology
[0002] Distillery lees are a major byproduct of the brewing process, rich in organic matter, protein, amino acids, trace elements, and a small amount of alcohol. They can be processed into highly efficient organic fertilizer, thus achieving resource recycling and reducing environmental pollution. Chinese patent document CN210176739U discloses a device for converting distillery lees into bio-organic fertilizer. This device uses a high-speed motor-driven crushing roller to break up the lees, a filter plate to screen the crushed lees, and a combination of a cam, slide plate, and spring to accelerate the lees' fall from the filter plate. A fermentation chamber is used to ferment the crushed and screened lees, facilitating thorough fermentation and resulting in higher quality organic fertilizer. However, during the sliding motion of the filter plate, the cavity of the device is connected to the external environment, causing lees to splash into the environment, resulting in pollution. Meanwhile, during the fermentation of distiller's grains, a large amount of water is generated in the distiller's grains due to the combined effects of microbial metabolism, organic matter decomposition, and physical circulation. Excessive water not only compresses the pores of the pile and prevents air circulation, thus inhibiting the biological activity of aerobic substances and prolonging the fermentation cycle, but also easily leads to leakage of fermentation liquid and environmental pollution. The device in the aforementioned patent literature does not effectively guide water, which causes the water generated during the fermentation process to submerge the fermentation material, affecting the fermentation process and hindering the long-term storage of organic fertilizer. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a device for producing organic fertilizer from distiller's grains waste. This device can not only effectively avoid splashing of distiller's grains waste during the screening process, but also effectively guide water and aerate the compost during the fermentation process, thereby improving fermentation efficiency and ensuring fermentation effect.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] An apparatus for producing organic fertilizer from distiller's grains waste includes a crushing box, a screening box, a fermentation box, and a collection box. The crushing box is located on one side of the screening box, and a crushing component is installed inside the crushing box. A screening cylinder is installed inside the screening box, and the screening cylinder has a structure that slopes from the side closer to the crushing box to the side farther away from the crushing box. The end of the screening cylinder away from the crushing box is rotatably connected to the inner wall of the screening box, and the end of the screening cylinder closer to the crushing box passes through the corresponding side wall of the screening box and is rotatably connected. A filter screen is installed on the bottom surface of the screening cylinder inside the screening box.

The bottom end of the screening box is connected to the fermentation box through a connecting pipe, and a fermentation tank and a stirring component are installed inside the fermentation box. The collection box is located below the fermentation box and is connected to the bottom of the fermentation box through a water guide pipe.
[0006] Based on further optimization of the above scheme, the side wall of the crushing box is connected to the side wall of the screening box through a connecting block, and a positioning bracket is set on the bottom surface of the crushing box away from the screening box; a feeding funnel with a larger top and a smaller bottom is set on the top surface of the crushing box.
[0007] Based on further optimization of the above scheme, the crushing component includes two rotating shafts and two crushing rollers. The two rotating shafts are arranged in parallel and their central axes are located on the same horizontal plane. The two ends of the two rotating shafts are respectively rotatably connected to the corresponding side wall of the crushing box; a crushing roller is fixedly sleeved on the outer wall of each of the two rotating shafts.
[0008] Based on further optimization of the above scheme, the screening cylinder is controlled to rotate by a drive assembly set on the outside of the screening box. The drive assembly includes a driven gear, a drive gear and an auxiliary gear ring. The driven gear is fixedly sleeved on the outer wall of the screening cylinder outside the screening box. A rotating drive gear is set on the outer wall of the screening box and corresponding to the driven gear. The drive gear is an incomplete gear. The tooth segment of the drive gear can mesh with the driven gear. An auxiliary gear ring is set on the outer ring of the drive gear and the driven gear. The end of the driven gear away from the drive gear meshes with the inner teeth of the auxiliary gear ring. The tooth segment of the drive gear can mesh with the inner teeth of the auxiliary gear ring.
[0009] Based on further optimization of the above scheme, the gear rod of the drive gear is fixedly connected to a rotating shaft.
[0010] Based on further optimization of the above scheme, the bottom surface of the fermentation tank is fixedly connected to the end face of the rotating seat that is rotatably set on the bottom surface of the fermentation tank; several water outlet holes are evenly opened at the bottom of the side wall of the fermentation tank and the inner wall of the fermentation tank is covered with gauze, which is used for water permeability and avoids the water outlet holes being blocked by lees waste.
[0011] Based on further optimization of the above scheme, the stirring assembly includes a stirring bracket, a stirring shaft, and stirring rods. The stirring bracket is fixedly installed on the inner wall of the connecting pipe, and the stirring shaft is fixedly installed in the middle of the bottom surface of the stirring bracket.

[0013] The following are the technical effects of this utility model:
[0014] The device first crushes the fed distiller's grains waste using a crushing component. Then, a reciprocating rotating screening cylinder screens the crushed waste. During screening, the waste does not splash due to centrifugal force, thus avoiding environmental pollution. Simultaneously, the reciprocating rotating screening cylinder effectively prevents waste from accumulating inside the cylinder and preventing fine particles from failing to pass through the filter, significantly improving screening efficiency. Next, a rotating fermentation tank creates centrifugal force, effectively expelling moisture during fermentation and preventing water from submerging the fermentation material, which would affect fermentation efficiency and results. Furthermore, in conjunction with the stirring component, it ensures thorough mixing of the fermentation material and the inoculant, guaranteeing the loose and breathable nature of the fermentation material.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1:
[0023] An apparatus for producing organic fertilizer from distiller's grains waste includes a crushing box 10, a screening box 20, a fermentation box 30, and a collection box 40. The crushing box 10 is located on one side of the screening box 20, and a crushing assembly is installed inside the crushing box 10. (Refer to...) Figure 1 As shown, the side wall of the crushing box 10 is connected to the side wall of the screening box 20 via a connecting block 15, and a positioning bracket 16 is provided on the bottom surface of the crushing box 10 away from the screening box 20 (the positioning of the crushing box 10 is achieved by the connection block 15 and the positioning bracket 16); a feeding funnel 13 with a larger top and a smaller bottom is provided on the top surface of the crushing box 10 (e.g., ...). Figure 1 (As shown). Combined Figure 1 and Figure 2 As shown: The crushing assembly includes two rotating shafts 11 and two crushing rollers 12. The two rotating shafts 11 are arranged in parallel and their central axes are located on the same horizontal plane (e.g., Figure 2 As shown), the two ends of the two rotating shafts 11 are respectively rotatably connected to the corresponding side walls of the crushing box 10, and the same side of the two rotating shafts 11 (for example, Figure 1 The left side shown (set according to actual situation) penetrates the corresponding side wall of the crushing box 10 and is driven by a pair of meshing gears; a crushing roller 12 (as shown) is fixedly sleeved on the outer wall of each of the two rotating shafts 11. Figure 2 As shown, several crushing teeth are evenly distributed on the outer wall of the crushing roller 12.
[0024] The screening box 20 has a screening cylinder 21 inside, and the screening cylinder 21 is inclined from the side closer to the crushing box 10 to the side farther away from the crushing box 10 (i.e. Figure 1 The structure shown is inclined from right to left, with the screening cylinder 21 at the end furthest from the crushing box 10 (i.e., Figure 1 The left end shown is rotatably connected to the inner wall of the screening box 20, and the end of the screening cylinder 21 closest to the crushing box 10 (i.e., the left end shown) is rotatably connected to the inner wall of the screening box 20. Figure 1The right end shown penetrates through the side wall of the corresponding screening box 20 and is rotatably connected. The screening cylinder 21 is located on the bottom surface of the inner cavity of the screening box 20 and a filter screen 211 is installed (combined with...). Figure 1 and Figure 4 As shown, on the entire circumference of the screening cylinder 21, i.e., in the longitudinal sectional view of the screening cylinder 21, the filter screen 211 is arc-shaped and the arc length of the filter screen 211 is no greater than one-third of the circumference of the entire screening cylinder 21; the bottom end of the crushing box 10 is connected to the inner cavity of the screening cylinder 21 through the guide pipe 14, and the guide pipe 14 passes through the corresponding side wall of the screening cylinder 21 and is rotatably connected (e.g. Figure 1 As shown, the feed pipe 14 consists of a bent section and a main body. The bent section connects the crushing box 10 and the main body. The central axis of the main body is collinear with the central axis of the screening cylinder 21. The end of the main body away from the bent section passes through the side wall of the screening cylinder 21 and is rotatably connected. The screening cylinder 21 is controlled to rotate by a drive assembly located outside the screening box 20. The drive assembly includes a driven gear 212, a drive gear 22, and an auxiliary gear ring 23. Figure 1 and Figure 3 As shown: The screening cylinder 21 is located outside the screening box 20 (i.e. Figure 1 The driven gear 212 is fixedly sleeved on the outer wall of the screening box 20 (shown on the right). A rotating drive gear 22 is set on the outer wall of the screening box 20 corresponding to the driven gear 212. The drive gear 22 is an incomplete gear (the drive gear 22 is sleeved on the outer wall of the gear rod and the gear rod is set on the outer wall of the screening box 20, and the tooth segment of the drive gear 22 is less than half of its circumference). The tooth segment of the drive gear 22 can mesh with the driven gear 212. An auxiliary tooth ring 23 is set on the outer ring of the drive gear 22 and the driven gear 212 (the auxiliary tooth ring 23 is located on the side of the screening box 20 close to its own central axis and several sliders are evenly arranged around it, generally 3 to 5. The outer wall of the screening box 20 has an annular groove corresponding to the slider. The slider slides and engages in the annular groove to realize the positioning of the auxiliary tooth ring 23 and ensure its rotation). The end of the driven gear 212 away from the drive gear 22 meshes with the inner teeth of the auxiliary tooth ring 23. The tooth segment of the drive gear 22 can mesh with the inner teeth of the auxiliary tooth ring 23. The gear rod of the drive gear 22 is fixedly connected to a rotating shaft 11 (e.g.) Figure 1 As shown, one end of a rotating shaft 11 near the screening box 20 passes through the corresponding side wall of the crushing box 10 and is connected to the gear rod of the drive gear 22 via a coupling. The other end of the rotating shaft 11 away from the drive gear 22 also passes through the corresponding side wall (i.e., the right side wall) of the screening box 20 and is connected to the output shaft of the drive motor located on the outside of the screening box 20, thereby realizing the drive.
[0025] The bottom of the screening box 20 is connected to the fermentation box 30 via a connecting pipe 24, and the fermentation box 30 is equipped with a fermentation tank 31 and a stirring assembly; the bottom surface of the fermentation tank 31 is fixedly connected to the end face of a rotating seat rotatably mounted on the bottom surface of the fermentation box 30 (e.g., Figure 1As shown, a rotating seat is coaxially mounted on the bottom surface of the fermentation tank 30. The rotating seat passes through the bottom surface of the fermentation tank 30 and is rotatably connected. The rotating seat is driven by a rotating motor mounted on the outer wall of the fermentation tank 30. Several water outlet holes are evenly opened at the bottom of the side wall of the fermentation tank 31 (the water outlet holes can be set as inclined holes from the outside of the central axis of the fermentation tank 31). The inner wall of the fermentation tank 31 is lined with gauze (the gauze can be made of a conventional water-permeable and air-permeable material in this field) to allow water to pass through while preventing the water outlet holes from being blocked by waste grains. The stirring assembly includes a stirring bracket 321, a stirring shaft 322, and a stirring rod 323. The stirring bracket 321 is fixedly mounted on the inner wall of the connecting pipe 24 (the stirring bracket 321 can be either Y-shaped or X-shaped, combined with...). Figure 1 and Figure 5 As shown, in this embodiment, the stirring support 321 is Y-shaped; at the same time, to avoid the accumulation of fermented material after screening on the end face of the stirring support 321, the longitudinal section of the stirring support 321 is an isosceles triangle structure, and a stirring shaft 322 is fixedly installed in the middle of the bottom surface of the stirring support 321. The end of the stirring shaft 322 away from the stirring support 321 is rotatably connected to the bottom surface of the inner cavity of the fermentation tank 31 (e.g., Figure 1 As shown, a locking block is fixedly installed in the middle of the bottom surface of the fermentation tank 31, and a locking groove is opened at the bottom end of the stirring shaft 322 corresponding to the locking block. The relative positioning of the stirring shaft 322 and the fermentation tank 31 is achieved by connecting the locking block and the locking groove. The stirring shaft 322 is located on the outer wall of the inner cavity of the stirring tank 31, and stirring rods 323 are evenly arranged (the number of stirring rods 323 is set according to the actual situation).
[0026] The collection box 40 is located below the fermentation box 30 and is connected to the bottom of the fermentation box 30 via a water guide pipe 41 (the water guide pipe 41 is evenly distributed around the central axis of the fermentation box 30 on its bottom surface, and a one-way valve is installed on the water guide pipe 41). A fixed support 26 is installed on the bottom surface of the screening box 20, located around the outer ring of the fermentation box 30 (in conjunction with...). Figure 1 and Figure 4 (As shown).
[0027] Working principle:
[0028] When in use, turn on the crushing assembly so that the two crushing rollers 12 rotate simultaneously and in opposite directions (i.e., Figure 2 (As shown, the left crushing roller 12 rotates clockwise and the right crushing roller 12 rotates counterclockwise). Simultaneously, due to the drive of the driven gear 212, the driving gear 22, and the auxiliary gear ring 23, the screening cylinder 21 rotates: the driving gear 22, as shown... Figure 3 As shown, when the drive gear 22 rotates counterclockwise and its teeth mesh with the driven gear 212, the drive gear 22 drives the driven gear 212 to interact with the screening cylinder 22 as shown. Figure 3 As shown, when the drive gear 22 rotates clockwise and its teeth mesh with the inner teeth of the auxiliary gear ring 23, the driven gear 212 and the screening cylinder 22 are driven by the drive gear 22 and the auxiliary gear ring 23. Figure 3 The screen cylinder 22 rotates counterclockwise as shown, thus achieving the cyclical rotation of the screen cylinder 22. At this time, waste lees are added to the crushing box 10, crushed by the crushing roller 12, and then enter the screen cylinder 21 through the feed pipe 14. The cyclical rotation of the screen cylinder 22 achieves the screening of the crushed material. The screened material enters the fermentation tank 31 through the connecting pipe 24. The fermentation tank 31 is rotated by the drive rotating seat, and centrifugal force is used to make the water produced after fermentation flow into the collection box 40 through the water outlet and the water guide pipe 41. At the same time, the rotation of the fermentation tank 31 causes it to rotate relative to the stirring rod 323 (the stirring rod 323 is stationary, and the fermentation tank 31 rotates relative to it), thereby making the stirring rod 323 stir the material in the fermentation tank 31, ensuring the permeability, looseness and uniformity of the material.
[0029] After fermentation is complete, the collection box 40 and fermentation box 30 can be lowered as a whole by a lifting device (an existing conventional lifting platform can be used, which will not be discussed in detail in this embodiment). This will cause the fermentation tank 31 to detach from the connecting pipe 24 and the stirring component, and then the organic fertilizer in the fermentation tank 31 can be taken out. Afterward, the collection box 40 and fermentation box 30 can be raised as a whole by a lifting device. This will cause the stirring component to reposition itself in the inner cavity of the fermentation tank 31, and the stirring shaft 322 to engage with the locking block at the bottom of the fermentation tank 31. The connecting pipe 24 can be inserted into the fermentation box 30 and fermentation tank 31 to start fermentation again and produce organic fertilizer.
[0030] Example 2:
[0031] As a further optimization of the present invention, to facilitate material feeding, based on the solution of Embodiment 1, the bottom of the inner cavity of the crushing box 10 located below the stirring assembly and the bottom of the inner cavity of the screening box 20 located below the screening cylinder 21 are both designed as a conical structure with a larger upper part and a smaller lower part (combined with...). Figure 1 , Figure 2 , Figure 4 (As shown).
[0032] Example 3:
[0033] As a further optimization of the present invention, in order to avoid filter clogging, based on the solution of Embodiment 1, referring to... Figure 4 As shown, cleaning brushes 25 are provided on both inner walls of the screening box 20 and corresponding to the filter screen 211, for real-time cleaning of the filter screen 211 during the rotation of the screening cylinder 21.
[0034] Example 4:
[0035] As a further optimization of the present invention, in order to prevent water from overflowing from the connection between the rotating seat and the fermentation tank 30 and causing pollution, based on the solution of embodiment 1, a water-blocking sleeve is provided on the bottom surface of the inner cavity of the fermentation tank 30 and on the outer ring of the rotating seat (that is, the water-blocking sleeve is coaxially provided with the rotating seat and the water-blocking sleeve is fixedly connected to the bottom surface of the fermentation tank 30), and the end face of the water-blocking sleeve is rotatably connected to the bottom surface of the fermentation tank 31.
