Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production and processing technology, specifically to a microbial enzymatic hydrolysis device for organic fertilizer production. Background Technology

[0002] Microbial enzymatic hydrolysis devices for organic fertilizer production are core equipment in the process of organic fertilizer resource utilization. Their technological development is closely related to the progress of agricultural waste resource utilization, microbial fermentation technology, and enzymatic reaction engineering. Organic wastes such as straw, livestock and poultry manure, and kitchen waste generated in agricultural production need to be catalyzed and degraded by enzymes (such as cellulase, protease, and amylase) produced by microbial metabolism to convert large organic molecules into small molecule nutrients (such as amino acids, sugars, and humic acid precursors) in order to form organic fertilizer that meets the absorption needs of crops. This enzymatic hydrolysis process requires specific environmental conditions and reaction carriers. As a result, microbial enzymatic hydrolysis devices have become a key link connecting the pretreatment of organic waste and the composting of organic fertilizer.

[0003] For example, patent document CN119286636A discloses an enzymatic hydrolysis device for microbial preparations, including a reaction vessel. A motor is mounted on the top of the reaction vessel, and a temperature control structure and auxiliary structures are located inside the vessel. The temperature control structure includes a rotating shaft located inside the reaction vessel. By using this temperature control structure, when the heat exchange medium is introduced into the vessel, it forms two opposing flow directions. A stirring rod, in conjunction with the heat exchange medium, regulates the temperature. Because the heat exchange medium flows in two directions, and because its temperature control effect gradually decreases during flow, the two flow directions of the heat exchange medium can compensate for each other, thus improving the efficiency of the process. Temperature control is more uniform, improving the effectiveness of temperature control and reducing product quality differences caused by uneven temperature distribution throughout the material. Although the above application has many beneficial effects, it still has the following shortcomings: The radial stirring mode mainly relies on horizontal material diffusion and lacks effective axial circulation power, which makes it easy for high-solids and high-viscosity organic substrates to form deposits at the bottom and corners of the tank wall. These deposits remain in a static state for a long time and cannot achieve uniform contact with enzyme solution and microorganisms. At the same time, existing enzyme addition methods are mostly one-time feeding or fixed batch replenishment, which lacks dynamic adaptation to the distribution of substrates and reaction process. This can easily lead to enzyme concentration imbalance due to local concentration differences of substrates, resulting in insufficient enzyme in substrate aggregation areas and failure to achieve effective degradation. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a microbial enzymatic hydrolysis device for organic fertilizer production.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a microbial enzymatic hydrolysis device for organic fertilizer production, including a heating tank, a motor is fixedly installed on the top of the heating tank through a heat insulation seat, and a timed feeding mechanism and a stirring mechanism are provided on the heating tank; The timed feeding mechanism includes multiple storage tanks, each of which is threaded with a lid. Each storage tank has a lifting rod slidably connected to its bottom wall. Each lifting rod has a connecting ball fixedly connected to its bottom end. Each lifting rod has a lifting plate fixedly connected to its top end. Each lifting plate has a spring fixedly connected to its bottom end. Each lifting plate has multiple sealing rods arranged in an array fixedly connected to its outer wall. The stirring mechanism includes a shaft and multiple support rings. Symmetrically arranged bottom blades are fixedly connected to the shaft near its bottom end. Symmetrically arranged mounting plates are fixedly connected to the upper, middle, and lower parts of the shaft. Moving rods are slidably connected to each mounting plate. Impact balls are fixedly connected to the top ends of the two top moving rods. Multiple symmetrically arranged stirring blades are fixedly connected to each moving rod. A transmission rod is fixedly connected to the bottom end of each moving rod. A transmission groove is formed on the support rings.

[0006] Specifically, the heating tank is fixedly connected to symmetrically arranged feed pipes, and the heating tank is fixedly connected to the center of the bottom end of the heating tank. Both the feed pipes and the discharge pipes are in a state of mutual communication with the heating tank, and the bottom end of the heating tank is fixedly connected to multiple support legs arranged in an array.

[0007] Specifically, there are four storage tanks in total. The storage tank array is threadedly connected to the top wall of the heating tank. The linkage ball is located at the bottom of the corresponding storage tank, and the lifting plate is located inside the corresponding storage tank.

[0008] Specifically, the bottom end of each spring is fixedly connected to the inner bottom wall of the corresponding storage tank, and the bottom end of each sealing rod slides through the bottom wall of the storage tank.

[0009] Specifically, the shaft is rotatably connected to the center of the top wall of the heating tank, the motor output end is fixedly connected to the top of the shaft, and the support rings are respectively fixedly connected to the corresponding transmission rod positions on the inner wall of the heating tank.

[0010] Specifically, one end of each transmission rod is slidably connected inside the corresponding transmission groove, each support ring has four protruding positions, and the mounting plates are staggered and mounted on the shaft.

[0011] The beneficial effects of this invention are: The stirring mechanism drives the mounting plate, moving rod, and stirring blades to rotate via the shaft. At the same time, the transmission rod slides along the transmission groove of the support ring. The protruding structure of the transmission groove forces the moving rod to complete axial up-and-down reciprocating motion during rotation, achieving four lifting and lowering movements per revolution. Combined with the stirring action of the bottom blades, a three-dimensional stirring mode of radial rotation and axial lifting and lowering is formed, which completely solves the material sedimentation problem caused by the lack of axial power in traditional radial stirring. This ensures that high-solids-content, high-viscosity organic substrates have no dead zones and are in full contact with enzyme solutions and microorganisms.

[0012] The timed feeding mechanism uses the impact ball of the stirring mechanism and the linkage ball of the storage tank to achieve intermittent and cyclic feeding of the enzymatic hydrolysate. When the impact ball rotates with the moving rod, it squeezes the linkage ball, driving the sealing rod to move upward and open the feeding channel. When there is no impact, the spring returns to close the channel. The four storage tanks are arrayed and feed one by one, replacing the traditional one-time or fixed batch replenishment method. This makes the enzymatic hydrolysate evenly dispersed as the reaction progresses, avoiding insufficient enzyme in the substrate aggregation area and excessive accumulation of enzyme in the sparse substrate area, thus ensuring the stability of the enzymatic hydrolysis reaction.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 5 The present invention provides the following technical solutions: A microbial enzymatic hydrolysis device for organic fertilizer production includes a heating tank 1, a motor 2 fixedly installed on the top of the heating tank 1 via a heat insulation seat, and a timed feeding mechanism 3 and a stirring mechanism 4 on the heating tank 1. The timed feeding mechanism 3 includes multiple storage tanks 31, each storage tank 31 is threaded with a cover 32, each storage tank 31 is slidably connected with a lifting rod 33, each lifting rod 33 is fixedly connected with a linkage ball 34 at the bottom end, each lifting rod 33 is fixedly connected with a lifting plate 35 at the top end, each lifting plate 35 is fixedly connected with a spring 36 at the bottom end, and each lifting plate 35 is fixedly connected with multiple sealing rods 37 arranged in an array on the outer wall of the lifting plate 35. The stirring mechanism 4 includes a shaft 41 and multiple support rings 42. Symmetrically arranged bottom blades 43 are fixedly connected to the shaft 41 near its bottom end. Symmetrically arranged mounting plates 44 are fixedly connected to the upper, middle and lower parts of the shaft 41. Moving rods 45 are slidably connected to the mounting plates 44. Impact balls 46 are fixedly connected to the top ends of the two top moving rods 45. Multiple symmetrically arranged stirring blades 47 are fixedly connected to the moving rods 45. Transmission rods 48 are fixedly connected to the bottom ends of the moving rods 45. Transmission grooves 49 are opened on the support rings 42.

[0018] A symmetrically arranged feed pipe 5 is fixedly connected to the heating tank 1, and a discharge pipe 6 is fixedly connected to the center of the bottom end of the heating tank 1. Both the feed pipe 5 and the discharge pipe 6 are interconnected with the heating tank 1. Multiple support legs 7 are fixedly connected to the bottom end of the heating tank 1 in an array. The feed pipe 5 facilitates the addition of materials into the heating tank 1, while the discharge pipe 6 facilitates the discharge of processed materials from the heating tank 1. The support legs 7 provide support for the heating tank 1. There are four storage tanks 31, which are threadedly connected to the top wall of the heating tank 1 in an array. The storage tanks 31 can be separated from the heating tank 1 by simply rotating them. The linkage ball 34 is located at the bottom end of the corresponding storage tank 31, the lifting plate 35 is located inside the corresponding storage tank 31, and the bottom end of the spring 36 is connected to the inside of the corresponding storage tank 31. The bottom wall is fixedly connected, and the spring 36 facilitates the resetting and movement of the lifting rod 33. The bottom end of the sealing rod 37 slides through the bottom wall of the storage tank 31. When the sealing rod 37 moves upward, it is no longer connected to the bottom wall. At this time, the enzymatic hydrolysate in the storage tank 31 will be discharged from the connection between the sealing rod 37 and the storage tank 31. The shaft 41 is rotatably connected to the center position of the top wall of the heating tank 1. The output end of the motor 2 is fixedly connected to the top end of the shaft 41. The motor 2 facilitates the rotation of the shaft 41. The support rings 42 are fixedly connected to the corresponding positions of the transmission rods 48 on the inner wall of the heating tank 1. One end of the transmission rods 48 is slidably connected to the inside of the corresponding transmission grooves 49. The support rings 42 are provided with four protrusions. The protrusions of the support rings 42 facilitate the upward movement of the transmission rods 48. The mounting plates 44 are installed on the shafts 41 in an alternating manner.

[0019] In use, a fixed amount of material can be added into the heating tank 1 through the feed pipe 5. Then, the heating tank 1 and the motor 2 are controlled to open and close via an external controller. When the heating tank 1 is started, it heats the material inside. When the motor 2 is started, it drives the shaft 41 to rotate. The rotation of the shaft 41 drives the bottom blade 43 and multiple mounting plates 44 to rotate. The mounting plates 44 drive the moving rod 45, the impact ball 46, the stirring blade 47, and the transmission rod 48 to rotate together. The transmission rod 48 rotates along the path of the transmission groove 49. When the transmission rod 48 rotates to the protruding position in the transmission groove 49, it is squeezed by the protruding position of the transmission groove 49, forcing the transmission rod 48 to follow the shaft. During the rotation of shaft 41, the transmission rod 48 moves upward, which in turn drives the moving rod 45 to move upward. The upward movement of the moving rod 45 drives the stirring blade 47 to move upward as it follows the rotation of shaft 41. At this time, the stirring blade 47 will perform radial rotation and upward movement. Each support ring 42 has four protrusions, so that the moving rod 45 and the stirring blade 47 perform four upward and downward movements during one revolution, thereby fully mixing and heating the material inside the heating tank 1. The upward movement of the stirring blade 47 and the rotating bottom blade 43 can also prevent the material inside the heating tank 1 from accumulating in large quantities. At the same time, the moving rod 41 moves upward. 5. During the radial rotation but not upward movement, the impact ball 46 will also rotate. The impact ball 46 will compress the linkage ball 34 along its rotation path. The linkage ball 34, under pressure, will move upward. This upward movement of the linkage ball 34 will cause the lifting rod 33 to move upward, which in turn will cause the lifting plate 35 to move upward. The upward movement of the lifting plate 35 will stretch the spring 36. Simultaneously, the upward movement of the lifting plate 35 will also cause multiple sealing rods 37 to move upward. The upward-moving sealing rods 37 are no longer connected to the bottom wall of the storage tank 31. At this point, the enzymatic hydrolysate inside the storage tank 31 will flow out from the bottom wall of the storage tank 31. When the impact ball 46 no longer compresses the linkage ball 34... Spring 36 will then drive lifting plate 35 and sealing rod 37 to reset. At this time, storage tank 31 will no longer discharge material into heating tank 1. During the rotation of the two impact balls 46, the four storage tanks 31 will repeatedly discharge material in different positions to complete the uniform feeding of enzymatic hydrolysate during the material reaction process. This allows the enzymatic hydrolysate to react more fully with the material inside heating tank 1 and avoids the occurrence of excessive addition of enzymatic hydrolysate in some areas. After the enzymatic hydrolysate in storage tank 31 is used up, it can be rotatably removed from heating tank 1. The cover 32 can be rotatably removed for feeding. After the organic fertilizer reaction is completed, it can be discharged through discharge pipe 6 to complete the processing.
