Description

Technical Field

[0001] This invention relates to the field of organic fertilizer fermentation equipment technology, and in particular to an organic fertilizer circulating fermentation tank. Background Technology

[0002] With the rapid development of large-scale farming, the amount of organic waste such as livestock and poultry manure is increasing day by day. The harmless treatment and resource utilization of these wastes have become important issues for the green development of agriculture. Aerobic composting is currently the mainstream technology for treating organic waste. The process requires the materials to be turned over regularly in the fermentation tank to replenish oxygen, regulate temperature, remove moisture, and promote microbial reproduction, thereby accelerating the decomposition and degradation of organic materials. In the existing trough fermentation process, a track-mounted turning machine straddling the fermentation tank is usually used to turn the materials.

[0003] Faced with the dynamic changes in material depth within the fermentation tank, existing turning machines, due to the inconvenience of adjusting the turning depth, often can only meet the turning needs of a specific material layer thickness. This results in the bottom material not being effectively turned up when the material is thick, becoming a fermentation "dead zone" and causing anaerobic acidification. On the other hand, when the material is thin, the turning rake is prone to running idle or scraping the bottom of the tank, affecting the turning effect and the lifespan of the equipment. Therefore, we designed an organic fertilizer circulating fermentation tank to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the turning depth of the trough fermentation turning machine in the prior art is difficult to adjust flexibly, resulting in uneven turning under different material layer thicknesses, and proposes an organic fertilizer circulating fermentation tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An organic fertilizer circulating fermentation tank, comprising: Fermentation tank body; Two parallel guide rails are fixedly connected to the top of the fermentation tank body; Two sliders are slidably fitted onto the outer walls of the two guide rails, respectively; A movable shell, whose two ends are respectively fixedly connected to the tops of the two sliders, and the movable shell has an opening along its length; The material turning component is vertically and vertically installed in the opening of the movable shell via a lifting mechanism, and is used to turn the material in the fermentation tank body. The material turning assembly includes a lifting plate, a turning motor, at least one pair of upright plates, a rotating rod, a turning roller, and multiple turning rakes; the lifting plate is located inside the opening of the movable shell; the turning motor is fixedly connected to the top of the lifting plate; the two upright plates are fixedly connected to the bottom of the lifting plate; the rotating rod is rotatably connected between the two upright plates; the turning roller is coaxially fixedly sleeved on the outer wall of the rotating rod; the multiple turning rakes are circumferentially fixedly connected to the outer wall of the turning roller; the output shaft of the turning motor is connected to the rotating rod via a second synchronous belt drive. An aeration mechanism, located at the bottom of the fermentation tank body, is used to introduce air into the material. A feeding assembly is disposed on one side of the fermentation tank body; The discharge assembly is located on the other side of the fermentation tank body.

[0006] Preferably, the system further includes a moving mechanism for driving the movable housing to move along the guide rail. The moving mechanism includes a moving motor, at least two pairs of support legs, rotating wheels corresponding to the number of support legs, and at least two rotating rods. The moving motor is fixedly disposed in the inner cavity of the movable housing. The support legs are fixedly connected to the bottom of the movable housing. The rotating wheels are rotatably connected to the corresponding support legs, and their outer walls abut against the top of the guide rail. The rotating rods are coaxially fixedly connected between the two rotating wheels located on the same side. The output shaft of the moving motor is connected to the two rotating rods via a first synchronous belt drive.

[0007] Preferably, the lifting mechanism includes a lifting motor, a first gear, a second gear, a threaded rod, a hollow column, and at least one guide rod; the lifting motor is fixedly disposed in the inner cavity of the movable housing; the first gear is fixedly connected to the end of the output shaft of the lifting motor; the second gear meshes with the first gear; the threaded rod coaxially and fixedly passes through the second gear and one end is rotatably connected to the inner wall of the movable housing; the hollow column is sleeved on the threaded rod and threadedly connected to it; the top of the lifting plate is fixedly connected to the bottom of the hollow column; the upper end of the guide rod is fixedly connected to the inner top of the movable housing, and the lower end is fixedly connected to the top of the lifting plate.

[0008] Preferably, the movable housing has a first through-hole for the first synchronous belt to pass through; the lifting plate has a second through-hole for the second synchronous belt to pass through.

[0009] Preferably, the discharge component is arranged through a third through-hole opened on the fermentation tank body.

[0010] Preferably, the outer wall of the output shaft of the mobile motor and the outer wall of the rotating rod are both fixedly connected to the first pulleys, and the first synchronous belt is sleeved on the two first pulleys.

[0011] Preferably, the outer wall of the output shaft of the flip motor and the outer wall of the rotating rod are both fixedly connected to a second pulley, and the second synchronous belt is sleeved on the two second pulleys.

[0012] Preferably, the aeration mechanism includes a main air supply pipe and an aeration pipe assembly; the aeration pipe assembly consists of multiple interconnected aeration pipes and is fixed to the inner bottom of the fermentation tank body; the main air supply pipe is fixedly connected to the multiple aeration pipes, and its end penetrates through the wall of the fermentation tank body and is fixed.

[0013] Compared with the prior art, the beneficial effects of this invention are as follows: 1. By setting up a lifting mechanism in conjunction with the material turning component, the turning roller can be flexibly raised and lowered in the vertical direction under the drive of the lifting motor, so that the turning depth can be adjusted in real time according to the actual thickness of the material layer in the fermentation tank. Whether it is the newly added material with a thicker feed end or the material that has become thinner due to the reduction in volume during fermentation at the discharge end, it can be effectively turned and turned, eliminating the problem of "dead zone" of bottom material and shallow idling caused by the fixed turning depth of traditional equipment, and improving the uniformity of fermentation of the entire tank.

[0014] 2. By setting up a moving mechanism, the moving shell and the flipping component can move smoothly along the guide rail within the entire length of the fermentation tank. In conjunction with the lifting mechanism, the flipping depth and flipping position can be adjusted in two dimensions, enabling the equipment to adapt to the differences in the material state of different sections in the fermentation tank under continuous feeding and discharging processes, achieving precise flipping of the entire tank, and ensuring the continuity and stability of the fermentation process.

[0015] 3. By setting up a bottom aeration mechanism, air is continuously introduced into the material during the turning and turning process or between turning and turning operations. This works in conjunction with the turning and turning loosening effect of the turning component to ensure that the material is in full contact with oxygen, promote the activity of aerobic microorganisms, accelerate the decomposition and maturation of organic matter, effectively shorten the fermentation cycle, and improve the production efficiency of organic fertilizer.

[0016] In summary, this invention, through the coordinated design of a liftable material turning component and a bottom aeration mechanism, achieves all-round turning and oxygenation of materials at different depths in the fermentation tank. It solves the problem of uneven fermentation caused by the inability to adjust the turning depth in traditional turning equipment. It has the advantages of good fermentation uniformity, high production efficiency, and wide applicability, and has good prospects for promotion and application in the field of organic fertilizer trough fermentation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1 Reference Figures 1-5 An organic fertilizer circulating fermentation tank includes a fermentation tank body 1, two parallel guide rails 2, two sliders 3, a movable shell 4, a material turning component, an aeration mechanism, a feeding component 25, and a discharging component 26. In this embodiment, the fermentation tank body 1 is rectangular. The two guide rails 2 are fixedly connected to the top of the fermentation tank body 1 along its length. The guide rails 2 are preferably I-beams to ensure sufficient load-bearing capacity. The two sliders 3 are slidably fitted onto the outer walls of the two guide rails 2. The inner holes of the sliders 3 are adapted to the shape of the guide rails 2, thereby ensuring the stability of the movable shell 4 when moving along the guide rails 2. The two ends of the movable shell 4 are fixedly connected to the tops of the two sliders 3. The movable shell 4 has an opening along its length, which provides lifting space for the material turning component. The inner cavity of the movable shell 4 is used to install the driving components of the moving mechanism and the lifting mechanism, and serves a protective function.

[0021] To enable the movable shell 4 to move automatically along the guide rail 2, this embodiment also includes a moving mechanism. The moving mechanism includes a moving motor 5, at least two pairs of support legs 8, rotating wheels 9 corresponding to the number of support legs 8, and at least two rotating rods 7. The moving motor 5 is fixedly disposed within the inner cavity of the movable shell 4. The support legs 8 are fixedly connected to the bottom of the movable shell 4. The rotating wheels 9 are rotatably connected to the corresponding support legs 8, and their outer walls abut against the top of the guide rail 2. Thus, the rotating wheels 9 both support the movable shell 4 and achieve movement through friction. Rotating rods 7 are coaxially fixedly connected between two rotating wheels 9 on the same side, causing the two rotating wheels 9 on that side to rotate synchronously. The output shaft of the moving motor 5 is connected to the two rotating rods 7 via a first synchronous belt 6. Specifically, the outer wall of the output shaft of the mobile motor 5 and the outer wall of the rotating rod 7 are both fixedly connected to the first pulleys. The first synchronous belt 6 is sleeved on the two first pulleys, thereby transmitting power to the two rotating rods 7 to achieve synchronous drive of the rotating wheels 9 on both sides, ensuring that the mobile housing 4 moves linearly on the guide rail 2 without deflection. The mobile housing 4 has a first through-hole for the first synchronous belt 6 to pass through, which facilitates the transmission arrangement.

[0022] The material turning component is vertically and flexibly installed within the opening of the movable shell 4 via a lifting mechanism, used to turn the material within the fermentation tank body 1. The lifting mechanism includes a lifting motor 10, a first gear 11, a second gear 12, a threaded rod 13, a hollow column 14, and at least one guide rod 16. The lifting motor 10 is fixedly installed within the inner cavity of the movable shell 4. The first gear 11 is fixedly connected to the end of the output shaft of the lifting motor 10. The second gear 12 meshes with the first gear 11, forming a gear transmission that reduces speed and increases torque. The threaded rod 13 coaxially passes through the second gear 12 and is rotatably connected at one end to the inner wall of the movable shell 4. The hollow column 14 is sleeved on the outside of the threaded rod 13 and threadedly connected to it, thereby converting the rotational motion into the linear lifting motion of the hollow column 14. The upper end of the guide rod 16 is fixedly connected to the inner top of the movable shell 4, and the lower end is fixedly connected to the top of the lifting plate 15. The guide rod 16 moves parallel to the direction of movement of the hollow column 14, preventing the lifting plate 15 from rotating during lifting and ensuring that the turning component always enters the material vertically. The top of the lifting plate 15 is fixedly connected to the bottom of the hollow column 14, and the lifting plate 15 is located inside the opening of the movable shell 4 so as to install the tilting drive component.

[0023] The material turning assembly specifically includes a lifting plate 15, a turning motor 17, at least one pair of upright plates 19, a rotating rod 20, a turning roller 21, and multiple turning rakes 22. The turning motor 17 is fixedly connected to the top of the lifting plate 15, the two upright plates 19 are fixedly connected to the bottom of the lifting plate 15, the rotating rod 20 is rotatably connected between the two upright plates 19 via bearings, the turning roller 21 is coaxially fixedly sleeved on the outer wall of the rotating rod 20, and multiple turning rakes 22 are circumferentially fixedly connected to the outer wall of the turning roller 21. The turning rakes 22 may adopt a curved plate structure, and their ends may have hooks to improve the ability to grasp and turn materials. The output shaft of the turning motor 17 is connected to the rotating rod 20 via a second synchronous belt 18. Specifically, second pulleys are fixedly connected to the outer wall of the output shaft of the turning motor 17 and the outer wall of the rotating rod 20, and the second synchronous belt 18 is sleeved on the two second pulleys to achieve reliable transmission. A second through-hole is provided on the lifting plate 15 for the second synchronous belt 18 to pass through, ensuring a smooth transmission path.

[0024] An aeration mechanism is located at the bottom inner interior of the fermentation tank body 1 to introduce air into the material, providing oxygen for aerobic fermentation. The aeration mechanism includes a main air supply pipe 23 and an aeration pipe assembly 24. The aeration pipe assembly 24 consists of multiple interconnected aeration pipes fixed to the bottom inner interior of the fermentation tank body 1. Each aeration pipe has several aeration holes or is equipped with a microporous aerator to ensure even air distribution. The main air supply pipe 23 is fixedly connected to the multiple aeration pipes, and its end penetrates the wall of the fermentation tank body 1 and is fixed thereto, connected to an external air pump or other air supply device. A feeding assembly 25 is located on one side of the fermentation tank body 1 to inject the organic fertilizer raw materials to be fermented into the fermentation tank. The feeding assembly 25 can be a belt conveyor. A discharging assembly 26 is located on the other side of the fermentation tank body 1 to discharge the fermented material. The discharging assembly 26 is arranged through a third through-hole in the fermentation tank body 1. This discharging assembly 26 can be a discharge conveyor for easy control of the discharge rate.

[0025] In this invention, air is injected into the main air supply pipe 23 by an external air pump. The air is then evenly discharged through multiple aeration pipes of the aeration pipe assembly 24, aerating and oxygenating the organic fertilizer in the fermentation tank body 1 to promote aerobic fermentation of microorganisms. When it is necessary to turn the material, the turning motor 17 is started. The output shaft of the turning motor 17 drives the rotating rod 20 to rotate via the second synchronous belt 18, which in turn drives the turning roller 21 and multiple turning rakes 22 to rotate, turning and loosening the material, allowing the material to fully contact the air, improving the uniformity and efficiency of fermentation. When it is necessary to turn the material at different locations in the fermentation tank, the moving motor 5 is started. The output shaft of the moving motor 5 drives the two rotating rods 7 and the rotating wheels 9 on both sides to rotate synchronously via the first synchronous belt 6. The rotating wheels 9 roll along the guide rail 2, thereby driving the moving shell 4 and the entire material turning assembly to move along the length of the fermentation tank, realizing the turning of the material in different sections of the fermentation tank. When the turning depth needs to be adjusted to accommodate material layers of different thicknesses, the lifting motor 10 is activated. The output shaft of the lifting motor 10, through the meshing of the first gear 11 and the second gear 12, drives the threaded rod 13 to rotate, thereby causing the hollow column 14 to rise and fall along the threaded rod 13. This, in turn, drives the entire turning assembly to rise and fall via the lifting plate 15, with the guide rod 16 extending and retracting accordingly to ensure smooth lifting. Thus, the turning rake 22 can be inserted into the material at different depths to meet the turning requirements of different fermentation stages. The material is injected from one end of the fermentation tank by the feeding component 25, and after continuous turning and aeration fermentation, it is discharged from the discharge component 26, achieving continuous or batch cyclic fermentation.

[0026] Example 2 Reference Figure 6 The difference between this embodiment and embodiment 1 is that the fermentation tank body 1 in this embodiment is a closed ring track structure. The track-shaped tank body is formed by two parallel straight line segments and semi-circular arc curves connecting the two ends of the two straight line segments, forming a ring trough for material fermentation. The material turning component is set above the side walls on both sides of the tank body. The material turning component is provided with a moving mechanism on both sides of the side walls of the tank body, which can be used to move on the side walls of the tank body. The moving mechanism can be an existing track wheel moving mechanism.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
