Description

Technical Field

[0001] The invention relates to the technical field of biological fermentation, in particular to a fermentation tank for standardized production of biological fertilizer. Background Art

[0002] In the production process of biological fertilizer, the fermentation tank plays a vital role. The biological fertilizer fermentation tank is usually composed of a tank body, a stirring device, a temperature control system, a ventilation system, a pressure control system, a pH detection and adjustment system, etc. Among them, the stirring device is of key significance to ensure the uniform mixing of the solution or material in the tank and the smooth progress of the reaction.

[0003] In the prior art, the impeller on the stirring device is usually fixed by screws. However, in practical applications, this fixing method has many problems.

[0004] When the impeller is used for a long time or the mixed liquid in the tank is relatively viscous, the screws will become loose. Once the screws are loose, the stability of the impeller will be affected. When the impeller is loose or falls off, it will bring a series of adverse consequences; First, it is impossible to achieve a uniform mixing effect, which will lead to uneven distribution of components in the solution or material, directly affecting the reaction process and the quality of the final product. Precipitation or accumulation may occur in local areas, which will not only cause great inconvenience to subsequent processing and operation, but may also cause delays in the entire production process. Secondly, in order to compensate for the problem of uneven mixing and achieve the desired mixing effect, it is often necessary to increase the mixing time and power, which will undoubtedly increase energy consumption, increase production costs, and reduce production efficiency; Furthermore, loose or detached impeller parts will collide and rub against the inner wall, other stirring parts or internal structures in the tank body. Such collision and friction will cause wear, scratches and even deformation of key parts such as the tank body and stirring shaft, seriously shortening the service life of the equipment; In addition, in actual fermentation operations, the viscosity of the mixed solution in the fermentation tank does not always remain constant, but will change greatly due to factors such as material composition and fermentation stage. When the viscosity of the mixed solution is high, the impeller that cannot adjust the angle will face many problems; that is, since the impeller angle is fixed, the fluid flow pattern it can produce is relatively single, which means that when facing solutions of different viscosities, it is impossible to flexibly change the flow state of the fluid in the fermentation tank, making it difficult to ensure that the materials are fully and evenly mixed; In the fermentation process of aerobic microorganisms, the supply of oxygen is crucial. However, the fixed-angle impeller cannot promote the gas-liquid contact in the fermentation liquid by optimizing the angle, making it difficult to enhance the dissolution and transfer of oxygen, and cannot meet the vigorous demand for oxygen for microbial growth. This will directly affect the growth rate and metabolic activity of the bacteria, and thus have an adverse effect on the fermentation effect and product quality.

[0005] Therefore, the present invention proposes a fermentation tank that can assist in tightening the impeller when the impeller rotates to stir the solution, thereby improving the tightening effect; can enable the impeller to move up and down during stirring to improve the uniformity of stirring; can automatically change the impeller angle according to the liquid concentration in the fermentation tank, thereby improving the disturbance mixing effect and assisting in the standardized production of fermentation biological fertilizers to solve the above problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a fermentation tank for standardized production of biological fertilizer to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions: a fermentation tank for standardized production of biological fertilizer, comprising: a tank body, a filling port, an endoscope lens, other auxiliary pipelines, and a driving device, wherein the filling port, the endoscope lens, other auxiliary pipelines, and the driving device are all fixedly connected to the tank body, and further comprising: a stable mixing maintenance component and a material property adaptation component, wherein the material property adaptation component is arranged inside the stable mixing maintenance component; The stable mixing maintenance component includes a covering moving part for moving up and down; The material property adaptation component includes a feedback capsule for withstanding the impact change of the fermentation mixed solution.

[0009] As an improvement, an auxiliary cavity is provided in the covered movable part, a piston push rod is vertically slidably connected in the auxiliary cavity, the top end of the piston push rod is fixedly connected to the bottom end of the rotating column, a cylindrical capsule is fixedly connected to the bottom of the auxiliary cavity of the covered movable part, an auxiliary spring body is equidistantly fixedly connected to the annular wall of the auxiliary cavity of the covered movable part, an arc-shaped piece is fixedly connected to one end of the auxiliary spring body away from the annular wall of the auxiliary cavity, a plug-in column is fixedly connected to the arc-shaped piece, and the plug-in column is movably plugged into the auxiliary spring body.

[0010] As an improvement, a fixed plate body is fixedly connected to the outer ring wall of the covering movable part by screws, a limiting hole is provided on the fixed plate body, an impeller is fixedly connected to the fixed plate body by a driving shaft, and through holes are equidistantly provided on the impeller.

[0011] As an improvement, the material property adaptation component also includes a guide channel opened on the fixed plate body, a first N-shaped part is fixedly connected in the guide channel, and drainage ports are equidistantly opened on both side walls of the first N-shaped part, the feedback capsule is fixedly connected to the top of the inner wall of the first N-shaped part, an auxiliary long strip is fixedly connected to the bottom of the inner cavity of the feedback capsule, and a main electric contact strip is fixedly connected to the top of the auxiliary long strip.

[0012] As an improvement, a second N-shaped part is fixedly connected to the top of the inner cavity of the feedback capsule, and magnetic bars are symmetrically fixedly connected to the two side walls of the second N-shaped part. Auxiliary electric contact strips A and B are fixedly connected to the inner surface of the magnetic bar, and the auxiliary electric contact strip B is located above the auxiliary electric contact strip A.

[0013] As an improvement, the cylindrical capsule is made of rubber material, and when the cylindrical capsule is squeezed by the piston push rod, the shape will change, that is, the original cross-sectional radius will increase.

[0014] As an improvement, both ends of the auxiliary strip are made of magnetic material.

[0015] Compared with the prior art, the present invention provides a fermentation tank for standardized production of biological fertilizer, which has the following beneficial effects: 1. By setting up a stable mixing maintenance component, the fermentation mixed solution in the tank body is stirred at the impeller. During auxiliary fermentation, it can effectively avoid the loosening of the impeller and the drive shaft during long-term use or when the mixed solution in the tank body is relatively viscous. That is to say, during the rotation of the impeller, the plug-in column will be plugged into the limiting hole of the fixed plate body connected to it, so as to ensure that when the impeller rotates with the main cavity as the axis, the fixing screws will not be loosened due to the lateral obstruction of the fermentation mixed solution in the tank body. This setting effectively guarantees the uniform mixing effect of the fermentation solution, prevents the precipitation or accumulation of the solution in the local area due to the loose impeller, and effectively avoids causing great inconvenience to subsequent processing and operation. Moreover, the loose or detached impeller will not collide and rub against the inner wall in the tank body, thereby avoiding wear, scratches and even deformation of key components such as the tank body and the stirring shaft, and greatly extending the service life of the equipment.

[0016] 2. The wave groove and the sliding part can be set to assist the covered moving part to indirectly drive the impeller to move up and down while rotating and stirring. This setting can effectively improve the mixing of the fermentation solution in the tank body on the basis of uniform stirring; at the same time, during the up and down movement of the impeller, the fermentation solution in the tank body will pass through the through holes opened on the impeller. This setting can also improve the solution mixing effect, thereby providing favorable assistance for the overall working process.

[0017] 3. The mixing effect can be optimized by adapting the setting of the components to the material characteristics, that is, different impeller angles can change the flow pattern of the fluid in the tank, so that the materials can be mixed more fully and evenly; secondly, it can adapt to different material characteristics, that is, for materials with high viscosity or containing larger particles, a more suitable stirring method can be found by changing the impeller angle, thereby improving stirring efficiency and reducing energy consumption; and it can improve oxygen transfer efficiency, that is, a suitable impeller angle can promote gas-liquid contact in the fermentation liquid, enhance the dissolution and transfer of oxygen, and meet the oxygen demand of microbial growth, which is particularly important for the fermentation process of aerobic microorganisms and can increase the growth rate and metabolic activity of the bacteria.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention is further described in detail below based on the accompanying drawings and embodiments. Example

[0022] Please refer to Figures 1 to 6 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a fermentation tank for standardized production of biological fertilizer, including: a tank body 1, a filling port 2, an endoscope lens 3, other auxiliary pipelines 4, and a driving device 5, wherein the filling port 2, the endoscope lens 3, other auxiliary pipelines 4, and the driving device 5 are all fixedly connected to the tank body 1, and also include: a stable mixing maintenance component 6, a material property adaptation component 7, and the material property adaptation component 7 is arranged inside the stable mixing maintenance component 6; The stable mixing maintenance component 6 includes a coated moving part 605 for moving up and down; the stable mixing maintenance component 6 also includes a main cavity 601 fixedly connected to the rotating shaft of the driving device 5, a rotating column 602 is rotatably connected in the main cavity 601, a wave groove 603 is opened on the rotating column 602, a sliding part 604 is slidably connected in the wave groove 603, the coated moving part 605 is movably sleeved at the bottom of the rotating column 602, the sliding part 604 is fixedly connected to the top of the coated moving part 605, an auxiliary cavity 606 is opened in the coated moving part 605, a piston push rod 607 is vertically slidably connected in the auxiliary cavity 606, and the top of the piston push rod 607 is fixedly connected to the bottom of the rotating column 602 A cylindrical capsule 608 is fixedly connected to the bottom of the auxiliary cavity 606 covering the moving part 605, and an auxiliary spring body 609 is equidistantly fixedly connected to the annular wall of the auxiliary cavity 606 covering the moving part 605. An arc piece 610 is fixedly connected to the end of the auxiliary spring body 609 away from the annular wall of the auxiliary cavity 606, and a plug-in column 611 is fixedly connected to the arc piece 610. The plug-in column 611 is movably plugged into the auxiliary spring body 609. A fixed plate body 612 is fixedly connected to the outer ring wall of the covering moving part 605 by screws, and a limiting hole 613 is provided on the fixed plate body 612. An impeller 614 is fixedly connected to the fixed plate body 612 through a driving shaft, and the impeller 614 is equidistantly provided with through holes 615.

[0023] in: Filling port 2 is mainly used for filling fermentation materials.

[0024] Relevant personnel can observe the fermentation process in the tank body 1 through the endoscope lens 3.

[0025] The driving device 5 is mainly used to provide services for the rotation of the main cavity 601. Specifically, the driving device 5 can be implemented as a driving motor.

[0026] The stable mixing maintenance component 6 is mainly used to prevent the impeller 614 from loosening and falling off when stirring the fermented mixed solution in the tank body 1, thereby affecting the stirring work; it can realize self-tightening of the impeller 614 during stirring and improve the stirring effect.

[0027] The rotating column 602 is driven by a motor. The sliding member 604 and the wave groove 603 are slidably matched.

[0028] The covering movable member 605 is also provided with a hole having the same size as the limiting hole 613 provided on the fixed plate 612 .

[0029] The auxiliary chamber 606 and the piston push rod 607 are slidably adapted to each other.

[0030] When the cylindrical capsule 608 is squeezed by the piston push rod 607, the shape will change, that is, the original cross-sectional radius will increase. At this time, the cylindrical capsule 608 will push the arc piece 610 to move its position, thereby providing assistance for the plug-in column 611 to be plugged into the limiting hole 613, thereby preventing the impeller 614 from causing the fixed plate body 612 connected to it to separate from the covering movable part 605 during the lateral rotation, causing the impeller 614 to fall off.

[0031] The through hole 615 is mainly used to ensure the flow of the fermentation mixed solution when the impeller 614 moves up and down in the tank body 1.

[0032] For further examples, please refer to Figure 1 , Figure 2 , Figures 6 to 10 As shown: The material property adaptation component 7 includes a feedback capsule 704 for withstanding the impact of the fermentation mixed solution and the changes. The material property adaptation component 7 also includes a guide channel 701 opened on the fixed plate 612, and a first N-shaped part 702 is fixedly connected in the guide channel 701. The two side walls of the first N-shaped part 702 are equidistantly provided with drain ports 703. The feedback capsule 704 is fixedly connected to the top of the inner wall of the first N-shaped part 702, and an auxiliary strip 705 is fixedly connected to the bottom of the inner cavity of the feedback capsule 704. The top of the auxiliary strip 705 is fixedly connected to the main electric contact strip 706, and the top of the inner cavity of the feedback capsule 704 is fixedly connected to the second N-shaped part 707. The two side walls of the second N-shaped part 707 are symmetrically fixedly connected to magnet strips 708, and the inner surface of the magnet strip 708 is fixedly connected to auxiliary electric contact strips A709 and auxiliary electric contact strips B710, and the auxiliary electric contact strip B710 is located above the auxiliary electric contact strip A709.

[0033] in: The material property adaptation component 7 is mainly used to detect the consistency of the mixed fermentation solution in the tank body 1, so as to change the inclination angle of the impeller 614 according to the specific situation. For materials with high viscosity or containing large particles, the stirring efficiency can be improved and the energy consumption can be reduced by changing the angle of the impeller 614.

[0034] When the fermentation mixed solution passes through the diversion channel 701, the fermentation mixed solution will squeeze the feedback capsule 704 during the flow. When squeezing a more viscous fermentation mixed solution, the feedback capsule 704 is pushed and drives the auxiliary strip 705 to move a distance greater than the moving distance of squeezing a more sparse fermentation mixed solution.

[0035] Both ends of the auxiliary strip 705 are made of magnetic material and can be attracted to the magnet strip 708 .

[0036] The main electric contact strip 706 and the auxiliary electric contact strip A709 and the auxiliary electric contact strip B710 are all electrically connected. The difference is that when the main electric contact strip 706 and the auxiliary electric contact strip B710 are in contact, the deflection angle of the impeller 614 controlled by the main controller is greater than the deflection angle when the main electric contact strip 706 and the auxiliary electric contact strip A709 are in contact, and when the main electric contact strip 706 and the auxiliary electric contact strip A709 and the auxiliary electric contact strip B710 are in contact, the main controller will capture the contact changes between the detection contacts in real time, and will control the rotation of the impeller 614 at the highest contact position of each change of contact of the main electric contact strip 706. If the viscosity of the fermentation mixed solution remains unchanged within a certain period of time, and the contact point of the main electric contact strip 706 each time it moves remains unchanged, then the main controller will only control the rotation axis of the impeller 614 to maintain the adjusted position unchanged.

[0037] Everything in the above example works like this: In the initial state: The sliding member 604 is located at the bottom of the wave groove 603; the cylindrical capsule 608 is not squeezed and deformed by the piston push rod 607, resulting in an increase in the radius of its cross section, which pushes the arc-shaped piece 610; the plug-in column 611 is not plugged into the limiting hole 613; The feedback capsule 704 is not squeezed and deformed by the fermentation mixed solution; the main electric contact strip 706 is not in contact with the auxiliary electric contact strip A709 or the auxiliary electric contact strip B710; and the auxiliary long strip 705 made of magnetic material at both ends is adsorbed by the magnet strip 708.

[0038] The following is the working process of the stable mixing maintenance component 6: When in use, the driving device 5 drives the main cavity 601 at the bottom to rotate. During the rotation of the main cavity 601, the rotating column 602 in the inner cavity of the main cavity 601 will rotate with the rotating column 602 driven by the internal motor. Since the sliding member 604 on the known coated moving member 605 is slidably connected in the wave groove 603 of the rotating column 602, when the rotating column 602 rotates, the coated moving member 605 inserted on the main cavity 601 will move under the cooperation of the sliding member 604 thereon and the wave groove 603 on the rotating column 602; and since the known wave groove 603 It is opened in a wave shape, so during the rotation of the rotating column 602, the coated moving part 605 will reciprocate up and down; further, when the coated moving part 605 reciprocates up and down compared to the filling port 2 of the main cavity 601, the piston push rod 607 fixedly connected at the bottom end of the rotating column 602 will reciprocate up and down in the auxiliary cavity 606 opened on the coated moving part 605. During the downward movement of the piston push rod 607, the piston push rod 607 will gradually approach the cylindrical capsule 608 provided in the auxiliary cavity 606, and contact and finally squeeze the cylindrical capsule 608 as it gradually approaches. Please refer to the attached Figure 4, since it is known that the arc-shaped piece 610 is surrounded and tightly attached to the surface of the columnar capsule 608, the squeezed columnar capsule 608 will push the plug-in column 611 to move into the limiting hole 613 provided on the fixed plate body 612 through the arc-shaped piece 610 during the squeezing and swelling, and the auxiliary spring body 609 will be compressed in this process; further, at this time, since the plug-in column 611 is laterally inserted into the limiting hole 613 provided on the fixed plate body 612, when the impeller 614 on the fixed plate body 612 moves laterally to disturb the fermentation mixed solution, the plug-in column 611 inserted in the limiting hole 613 will limit the position of the fixed plate body 612, and this insertion can ensure that the impeller 614 will not indirectly loosen the screws fixing the fixed plate body 612 due to the resistance of the fermentation mixed solution when disturbing the fermentation mixed solution, thereby ensuring the stability of the disturbance work; Furthermore, when the piston push rod 607 moves away from the cylindrical capsule 608, the cylindrical capsule 608 will return to its original state, and the auxiliary spring body 609 that was squeezed originally will indirectly make the plug-in column 611 no longer plugged into the limiting hole 613 on the fixed plate body 612 during the reset process; further, as the piston push rod 607 moves downward again, the cylindrical capsule 608 will be squeezed again, so as to repeat the above plug-in operation; Furthermore, by setting up the stable mixing maintenance component 6, the fermentation mixed solution in the tank body 1 is stirred at the impeller 614. When assisting fermentation, it is possible to effectively avoid the loosening of the impeller 614 and the drive shaft during long-term use or when the mixed solution in the tank body 1 is relatively viscous. That is to say, during the rotation of the impeller 614, the plug-in column 611 will be plugged into the limiting hole 613 of the fixed plate body 612 connected thereto, so as to ensure that the impeller 614 will not be loosened when the main cavity 601 is used as the rotation axis. The lateral obstruction of the fermentation mixed solution in the tank body 1 causes the fixing screws to loosen. This arrangement effectively ensures the uniform mixing effect of the fermentation solution, prevents the precipitation or accumulation of the solution in a local area due to the loosening of the impeller 614, and effectively avoids causing great inconvenience to subsequent processing and operation. Moreover, the loose or detached impeller 614 will not collide and rub against the inner wall of the tank body 1, thereby avoiding wear, scratches and even deformation of key components such as the tank body 1 and the stirring shaft, thereby greatly extending the service life of the equipment.

[0039] Furthermore, under the setting of the wave groove 603 and the sliding member 604, the covering moving member 605 can be assisted to indirectly drive the impeller 614 to move up and down while rotating and stirring. This setting can effectively improve the mixing of the fermentation solution in the tank body 1 on the basis of uniform stirring; at the same time, during the up and down movement of the impeller 614, the fermentation solution in the tank body 1 will pass through the through hole 615 opened on the impeller 614. This setting can also improve the solution mixing effect, thereby providing favorable assistance for the overall working process.

[0040] Please refer to the above working process Figures 1 to 6 .

[0041] The following is the working process of the material property adaptation component 7: Furthermore, when the coated moving member 605 is indirectly driven by the rotating column 602 to move up and down, the fixed plate 612 on the coated moving member 605 will also move up and down. During this process, the fermentation mixed solution in the tank body 1 will pass through the guide channel 701 opened on the fixed plate 612. For further information, please refer to the attached Figure 7 To Attachment Fig. 9 When the fermentation mixed solution passes through the guide channel 701, the fermentation mixed solution flows through the two sides of the first N-shaped member 702 and the drain port 703 on the first N-shaped member 702 respectively; It should be noted that: during the flow, the flowing fermentation mixed solution has high viscosity and low viscosity; When the viscosity of the fermentation mixed solution is high, the feedback capsule 704 fixedly connected to the first N-shaped member 702 is squeezed with greater force when the fermentation mixed solution flows, that is, the deformation is greater than when the viscosity of the fermentation mixed solution is low; Furthermore, when the fermentation mixed solution flows from the diversion channel 701, the feedback capsule 704 will be squeezed. At this time, the deformed feedback capsule 704 will move upward with the auxiliary strip 705 therein under the restriction of the second N-shaped member 707. Further, the main electric contact strip 706 on the auxiliary strip 705 will gradually approach and finally contact the auxiliary electric contact strip A709 or the auxiliary electric contact strip B710 provided on the inner wall of the second N-shaped member 707. Since it is known that the main electric contact strip 706 and the auxiliary electric contact strips A709 and B710 all have electric The difference is that when the main electric contact strip 706 and the auxiliary electric contact strip B710 are in contact, the deflection angle of the impeller 614 controlled by the main controller is greater than the deflection angle when the main electric contact strip 706 and the auxiliary electric contact strip A709 are in contact; under this setting, the viscosity of the fermentation mixed solution at this time can be fed back through the contact between the main electric contact strip 706 and the auxiliary electric contact strip A709 or the auxiliary electric contact strip B710, and the deflection angle of the impeller 614 can be changed according to the main controller, so as to improve the disturbance effect of the fermentation mixed solution; Furthermore, by adapting the setting of the material property adaptation component 7, the mixing effect can be optimized, that is, different impeller 614 angles can change the flow pattern of the fluid in the tank body 1, so that the material can be mixed more fully and evenly; secondly, it can adapt to different material properties, that is, for materials with higher viscosity or containing larger particles, a more suitable stirring method can be found by changing the impeller 614 angle, thereby improving stirring efficiency and reducing energy consumption; and it can improve oxygen transfer efficiency, that is, a suitable impeller 614 angle can promote gas-liquid contact in the fermentation liquid, enhance the dissolution and transfer of oxygen, and meet the oxygen demand of microbial growth, which is particularly important for the fermentation process of aerobic microorganisms and can increase the growth rate and metabolic activity of the bacteria.
