Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to an amino acid fertilizer liquid fermentation tank. Background Technology

[0002] The amino acid fertilizer liquid fermentation tank is the core equipment for producing amino acid fertilizers. It uses microbial fermentation technology to transform raw materials into liquid fertilizers rich in amino acids and other active ingredients. The tank is typically made of stainless steel. During operation, the fermentation broth containing proteins, plant and animal residues, and other raw materials is stirred and mixed thoroughly. Sterile air is then introduced to provide oxygen. Under specific conditions, microorganisms decompose the raw materials, converting macromolecules into smaller molecules such as amino acids and peptides. This equipment is widely used in agriculture, horticulture, and other fields. The amino acid fertilizers produced promote crop growth, enhance stress resistance, and improve the quality of agricultural products, playing a vital role in green agricultural production.

[0003] However, in practical use, the existing fermenters still have the following technical problems: Regarding cleaning and maintenance, the traditional integrated tank structure makes it difficult to thoroughly clean the material adhering to the inner walls of the fermenter, especially in dead areas such as the bottom of the tank and the stirring blades. Residual material easily breeds bacteria, affecting the subsequent fermentation quality, and cleaning is time-consuming and labor-intensive. Regarding handling, existing fermenters lack dedicated handling aids. Short-distance handling relies on forklifts to directly lift the tank, which can easily lead to localized deformation of the tank. Long-distance handling requires the use of a towing crane, but due to the lack of a suitable towing structure, operators often tie the towing rope directly to the tank, which not only easily scratches the tank surface but also easily causes the fermenter to tilt or tip over during handling due to a shift in the center of gravity, seriously threatening equipment safety and personnel safety. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the easy growth of miscellaneous bacteria due to the adhesion of materials on the inner wall, the lack of auxiliary structures for handling, the easy damage to the tank during handling, and the existence of safety hazards. Therefore, an amino acid fertilizer liquid fermentation tank is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An amino acid fertilizer liquid fermentation tank includes a base, a support frame fixedly connected to the top of the base, an upper tank body fixedly connected to the inner wall of the support frame, a top cover installed on the top of the upper tank body, a stirring assembly provided at the top of the top cover, a feed inlet on the top of the top cover, a sealing ring fixedly connected to the bottom of the inner wall of the upper tank body, a waterproof ring provided on the inner wall of the sealing ring, a flange fixedly connected to the bottom of the outer wall of the upper tank body, a lower tank body connected to the flange by two fixing bolts, a sealing groove provided on the side of the lower tank body adjacent to the upper tank body, an O-ring detachably connected to the inner wall of the sealing groove, a gasket fixedly connected to the top side of the inner wall of the lower tank body, the top of the gasket detachably connected to the inner wall of the sealing ring, and a discharge pipe fixedly connected to the bottom of the lower tank body.

[0007] Furthermore, the support frame has multiple reserved through holes on its top side in a ring shape. The inner wall of each reserved through hole is detachably connected to a plug. A first traction ring is fixedly connected to the bottom side of the plug. A spring is provided on the inner wall of the plug. A connecting seat is threaded to the top of the outer side of the plug. A second traction ring is fixedly connected to the top of the connecting seat.

[0008] Furthermore, a traction base plate is connected to the outer side of the base via an installation assembly. The top of the traction base plate has a traction groove, and one end of the traction base plate is connected to the base via a fixing bolt.

[0009] Furthermore, the mounting assembly includes a mounting groove and a fixing bolt. The mounting groove is annularly formed on the outer side of the base, and a traction base plate is detachably connected to the inner wall of the mounting groove. The fixing bolt is threaded to the top edge of the base, and the bottom end of the fixing bolt passes through the adjacent end of the traction base plate.

[0010] Furthermore, the stirring assembly includes a sealing bushing, a motor is mounted on the top of the sealing bushing, the drive end of the motor passes through the sealing bushing and is fixedly connected to a shaft, and multiple stirring blades are fixedly connected to the outside of the shaft.

[0011] Furthermore, a forklift slot is provided at one end of the outer side of the base.

[0012] Furthermore, a valve is provided at the middle end of the discharge pipe.

[0013] Furthermore, the traction base plate is L-shaped.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model adopts a split, detachable structure and a double sealing system. By loosening the fixing bolts, the tank body can be separated, which can completely solve the problem of difficult cleaning of the inner wall of traditional fermenters. With the sealing structure composed of perfluoroether O-rings, waterproof rings and metal gaskets, it is resistant to acids and alkalis, high temperature and high pressure, and can adapt to complex working conditions. While achieving convenient cleaning and maintenance, it effectively prevents material leakage and bacterial contamination, and balances cleaning efficiency and sealing reliability.

[0016] 2. In terms of handling safety, the innovative design of the forklift tray and traction component fills the functional gap of traditional fermentation tanks. The forklift tray meets the needs of convenient short-distance handling, and the traction component balances the center of gravity through multi-point traction, avoiding direct force damage to the tank body. This solves the problem that traditional traction can easily lead to tank damage and unstable center of gravity, and comprehensively improves the convenience, reliability and safety of using the fermentation tank.

[0022] 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.

[0023] Reference Figures 1-3An embodiment of this utility model provides an amino acid fertilizer liquid fermentation tank, including a base 1, a support frame 2 fixedly connected to the top of the base 1, an upper tank body 3 fixedly connected to the inner wall of the support frame 2, a top cover 4 installed on the top of the upper tank body 3, a stirring assembly provided at the top of the top cover 4, a feed inlet 7 opened at the top of the top cover 4, a sealing ring 29 fixedly connected to the bottom of the inner wall of the upper tank body 3, a waterproof ring 30 provided on the inner wall of the sealing ring 29, a flange 24 fixedly connected to the bottom of the outer wall of the upper tank body 3, a lower tank body 23 connected to the flange 24 by fixing bolts 25, a sealing groove 26 opened on the side of the lower tank body 23 close to the upper tank body 3, an O-ring 27 detachably connected to the inner wall of the sealing groove 26, a gasket 28 fixedly connected to the top side of the inner wall of the lower tank body 23, the top of the gasket 28 detachably connected to the inner wall of the sealing ring 29, and a discharge pipe 19 fixedly connected to the bottom of the lower tank body 23.

[0024] Specifically, the split-type structural design and multiple sealing guarantees effectively solve the problem of difficult cleaning of the inner wall of existing equipment. When cleaning and maintenance of the fermenter's interior is required, the operator can loosen the fixing bolts 25 to separate the lower tank 23 from the flange 24 connection, thereby fully exposing the inner wall surfaces of the upper tank 3 and the lower tank 23 for thorough cleaning. During reassembly after cleaning, the waterproof ring 30 is first embedded into the inner wall of the sealing ring 29 to form the first sealing barrier; then, the perfluoroether O-ring 27 is inserted into the sealing groove 26. This material has excellent acid and alkali resistance and high temperature resistance (withstands temperature ≥120℃), ensuring that it can withstand acid and alkali media erosion and high temperature sterilization environment during fermentation without aging or deformation; finally, the metal gasket 28 is inserted into the inner wall of the sealing ring 29. The metal gasket 28 can withstand high temperature and high pressure conditions, further enhancing the sealing reliability. Through the synergistic effect of flange 24 and the above-mentioned double sealing system (O-ring 27 + gasket 28), the detachable function of the lower tank 23 is realized, and the sealing requirements during the fermentation process are ensured to prevent material leakage and external bacterial contamination.

[0025] Reference Figures 1-3The support frame 2 has multiple pre-drilled through holes 13 on its top side. A plug 14 is detachably connected to the inner wall of each through hole 13. A first traction ring 16 is fixedly connected to the bottom of the plug 14. A spring 18 is provided on the inner wall of the plug 14. A connecting seat 15 is threaded to the top of the outer side of the plug 14. A second traction ring 17 is fixedly connected to the top of the connecting seat 15. A traction base plate 10 is connected to the outer side of the base 1 via an installation assembly. A traction groove 11 is formed at the top of the traction base plate 10. A near-end of the traction base plate 10 is connected to the base 1 via a fixing bolt 12. The installation assembly includes an installation groove 9 and a fixing bolt 12. 12. The mounting groove 9 is annularly formed on the outer side of the base 1. The inner wall of the mounting groove 9 is detachably connected to the traction base plate 10. The fixing bolt 12 is threadedly connected to the top edge of the base 1. The bottom end of the fixing bolt 12 passes through the end of the traction base plate 10. The stirring assembly includes a sealing bushing 5. A motor 6 is mounted on the top of the sealing bushing 5. The drive end of the motor 6 passes through the sealing bushing 5 and is fixedly connected to a shaft 21. Multiple stirring blades 22 are fixedly connected to the outside of the shaft 21. A forklift groove 8 is formed on one side of the base 1. A valve 20 is set in the middle of the discharge pipe 19. The traction base plate 10 is L-shaped.

[0026] Specifically, in terms of the handling structure, this utility model significantly improves the convenience and safety of equipment handling by setting up a forklift slot 8 and a traction component. In short-distance handling operations, operators can directly insert the forklift's plate into the forklift slot 8 on the outside of the base 1 to achieve quick and stable lifting and handling, avoiding the risk of damage to the tank caused by traditional hoisting methods. For slightly longer handling needs, the L-shaped traction base plate 10 is fixed to the outside of the base 1 using the mounting component. Specifically, the traction base plate 10 is embedded into the mounting slot 9 and tightened with fixing bolts 12; simultaneously, the plug 14 is inserted into the reserved through hole 13 on the top side of the support frame 2, and then threadedly locked using the connecting seat 15. The elastic preload provided by the spring 18 ensures the stable fixation of the plug 14. During the traction process, the traction rope is sequentially connected to the first traction ring 16 and the traction groove 11. The traction direction is adjusted by the guiding action of the traction groove 11, and the second traction ring 17 assists in the traction. This structural design effectively disperses stress concentration points during the traction process, avoiding direct tension on the tank and preventing damage. At the same time, multi-point traction balances the center of gravity of the equipment, significantly reducing the risk of tipping due to center of gravity shift during handling. The valve 20 is located in the middle of the discharge pipe 19, which can precisely control the discharge flow rate of the fermentation material, facilitating production operation management.

[0027] Working principle: When using this amino acid fertilizer liquid fermentation tank, raw materials are first fed into the tank through the feed inlet 7 of the top cover 4. The motor 6 drives the shaft 21 and stirring blades 22 inside the sealing bushing 5 to rotate, stirring and mixing the materials. The externally connected ventilation and temperature control systems work together to maintain a suitable fermentation environment. After fermentation, the valve 20 of the discharge pipe 19 is opened to discharge the material. When cleaning is required, loosen the fixing bolt 25 and separate the lower tank body 23 connected to the flange 24 to clean the inside of the tank. After cleaning, first insert the waterproof ring 30 into the sealing ring sleeve 29, then insert the perfluoroether O-ring 27 into the sealing groove 26, insert the metal gasket 28, and finally tighten the lower tank body 23 again with the fixing bolt 25. The double sealing system ensures the airtightness. During transport, for short distances, the forklift plate can be inserted into the forklift slot 8 to lift and transport the cargo; for long distance transport, first embed the L-shaped towing base plate 10 into the mounting slot 9 of the base 1 and fix it with the fixing bolt 12, then insert the plug 14 into the reserved through hole 13 and fix it through the connecting seat 15, connect the towing rope to the first towing ring 16 and the towing slot 11, and cooperate with the second towing ring 17 to ensure the center of gravity is stable during transport and avoid damage to the tank.

[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.
