Technical Field

[0001] The utility model relates to the technical field of biological equipment production, in particular to a fermentation tank for producing biological fertilizers. Background Technique

[0002] Biological fertilizer is a kind of fertilizer produced by using biotechnology, mainly composed of living microorganisms or their metabolites, and has many advantages such as environmental protection, strong sustainability, improving soil structure, increasing fertilizer utilization rate and enhancing plant resistance. It is a preparation containing active microorganisms, and these microorganisms can increase the supply of plant nutrients or improve plant growth through various biological processes. The main types include nitrogen-fixing bacteria fertilizers, phosphorus-solubilizing bacteria fertilizers, potassium bacteria fertilizers and compound microbial fertilizers. The production method of biological fertilizer involves three main steps: strain screening, fermentation culture and preparation processing. The application methods include seed coating, soil application and foliar spraying. When using, attention should be paid to suitable storage conditions, selecting the appropriate application time, and it can be used in combination with chemical fertilizers to obtain the best effect. The development trend of biological fertilizer includes strain improvement, compound preparation development and intelligent application. As an important trend in the development of agricultural production towards sustainability and ecological friendliness, biological fertilizer can not only increase the yield and quality of crops, but also maintain ecological balance. With the continuous progress of biotechnology and agricultural science and technology, its application scope and effect will be further expanded and improved, becoming one of the important directions for future agricultural development.

[0003] The fermentation tank is a key equipment in biotechnology and chemical engineering, mainly used in the fields of microorganism culture, enzyme preparation production and biological product manufacturing, etc. Its basic structure includes a tank body, a stirring system, a temperature control system, a ventilation system, a pH adjustment system, a sampling port and a control panel. The main function of the fermentation tank is to provide a closed environment for the growth of microorganisms, maintain suitable conditions such as temperature, pH value and dissolved oxygen, realize the uniform mixing of the culture medium and microorganisms, and facilitate the addition of nutrients and the extraction of products. According to the operation mode, scale and stirring mode, the fermentation tank can be divided into different types. It is widely used in many fields such as the food industry, the pharmaceutical industry, the chemical industry, the environmental protection field and agriculture. During the use process, key parameters such as temperature, pH value, dissolved oxygen, stirring speed and inoculation amount need to be strictly controlled. The development trend of the fermentation tank includes intelligentization, large-scale, multi-functionality, material innovation and energy conservation and environmental protection. However, the fermentation tank technology also faces challenges such as scale-up effect, pollution control, process optimization and cost control.

With the continuous development of biotechnology, the fermentation tank technology is also continuously progressing, making it possible for the large-scale production of various biological products.

[0004] Application No.: CN202223250183.1. The fermenter for producing biological fertilizer includes a bottom plate. There are movable casters at the bottom of the bottom plate. There are a fermenter and a feeding assembly on the bottom plate. There is a stirring assembly inside the fermenter. The top of the fermenter is connected with a feeding port and an adding port. Heating pipes are embedded on both the bottom wall and the side wall of the fermenter; the feeding assembly includes a motor A, a threaded rod, a threaded sleeve, a connecting rod A, a support plate, a feeding frame, and a rotating shaft; the stirring assembly includes a motor B, a rotating rod A, a bevel gear A, a bevel gear B, a rotating rod B, a stirring fan A, and a stirring fan B. The utility model aims to solve the technical problems of time-consuming and laborious manual handling and poor fermentation effect. However, in many fermenters, the materials cannot be slowly released inside the fermenter, but fall rapidly. The storage gaps of the materials inside the fermenter will not be uniform, so the fermentation effect will not reach the ideal effect.

[0005] Therefore, in view of this, in response to the existing deficiencies, research and improvement are carried out, and a fermenter for producing biological fertilizer is proposed. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a fermenter for producing biological fertilizer to solve the problems raised in the above background technology.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: A fermenter for producing biological fertilizer, including: a tank bottom, a top cover is arranged at the top end of the tank bottom, a tank body is arranged at the bottom end of the tank bottom, and an auxiliary structure is arranged at the middle part inside the tank bottom;

[0008] A bottom inner cavity is vertically arranged inside the tank bottom, and a compression resistance structure is vertically arranged inside the bottom inner cavity.

[0009] Furthermore, the auxiliary structure includes a tank ring, a torsion spring, a rotating shaft assembly, a receiving frame, a clamping plate, a receiving groove plate, a vertical cylinder, and a material guiding hole. A tank ring is arranged at the bottom end inside the tank bottom. A vertical cylinder is vertically arranged at the top end of the tank ring. A rotating shaft assembly is arranged on the outer side of the vertical cylinder. A torsion spring is arranged at one end of the rotating shaft assembly. A receiving groove plate is arranged at the front end of the rotating shaft assembly. A clamping plate is clamped on the outer side of the receiving groove plate. A receiving frame is arranged at one end of the clamping plate. A material guiding hole is opened inside the receiving frame. A rotating structure is formed between the rotating shaft assembly and the receiving groove plate, which is convenient for the rotating shaft assembly to help the receiving groove plate perform rotational activities.

[0010] Furthermore, a rectangular hole is opened on the outer surface of the receiving groove plate. The thickness of the rear end of the outer side of the clamping plate is greater than the thickness of the front end of the outer side of the clamping plate. The rectangular hole on the outer surface of the receiving groove plate and the clamping plate are in a clamping connection, which is convenient for the assembly of the clamping plate and the receiving groove plate.

[0011] Furthermore, the outer shape of the receiving frame is semi-circular, and the receiving frame is fixedly connected to the clamping plate to prevent the receiving frame from loosening when bearing materials with a large mass.

[0012] Furthermore, one end of the torsion spring is fixedly connected to the back surface of the receiving groove plate, and the other end of the torsion spring is fixedly connected to the outside of the clamping plate, which facilitates the torsion spring to slow down the flipping speed of the clamping plate.

[0013] Furthermore, the compression-resistant structure includes an embedded conical cylinder, a bottom shaft, a receiving conical cylinder, an outer wrapping piece and a compression spring assembly. The embedded conical cylinder is embedded on the inner side of the bottom inner cavity. The receiving conical cylinder is vertically embedded inside the embedded conical cylinder. A bottom shaft is arranged at the bottom end of the receiving conical cylinder, and a compression spring assembly is arranged at the bottom end of the bottom shaft. An outer wrapping piece is adhered to the top end of the embedded conical cylinder. The material of the outer wrapping piece is a flexible material, which facilitates the folding movement of the outer wrapping piece.

[0014] Furthermore, the center point of the receiving conical cylinder and the center of the tank ring are on the same straight line, which facilitates the introduction of materials.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, a large amount of materials vertically fall on the receiving frame at the top end of the tank ring. Since the clamping plate at one end of the receiving frame is combined with the receiving groove plate, and the rotating shaft assembly and the torsion spring clamped on the outside of the vertical cylinder help the receiving frame to form a downward flipping movement, and the torsion spring slows down the flipping amplitude of the receiving frame. The materials first contact the receiving frame, and part of the materials pass through the material guiding holes and enter the inside of the receiving conical cylinder. This slows down the speed of the materials entering, and at the same time, the materials will be stored in the bottom of the tank in portions.

[0017] 2. In the present utility model, when the materials enter the inside of the receiving conical cylinder, the receiving conical cylinder deposits downward inside the embedded conical cylinder. At the same time, the outer wrapping piece shrinks following the sinking of the receiving conical cylinder, and the bottom shaft and the compression spring assembly reduce the sinking speed of the bottom shaft. This prevents the materials from sinking too fast and resulting in uneven accumulation levels of the materials. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1-11 shown, a fermentation tank for producing biological fertilizer includes: a tank bottom 3, a top cover 1 is arranged at the top end of the tank bottom 3, a tank body 2 is arranged at the bottom end of the tank bottom 3, and an auxiliary structure 4 is arranged at the middle of the inside of the tank bottom 3;

[0032] A bottom inner cavity 6 is vertically arranged inside the tank bottom 3, and a compressive structure 5 is vertically arranged inside the bottom inner cavity 6.

[0033] As Figures 1-11As shown in the figure, a fermenter for producing biological fertilizer, the auxiliary structure 4 includes a tank ring 401, a torsion spring 402, a rotating shaft assembly 403, a receiving frame 404, a clamping plate 405, a receiving groove plate 406, a vertical cylinder 407 and a material guiding hole 408. At the bottom end inside the tank bottom 3, a tank ring 401 is provided. Vertically arranged at the top of the tank ring 401 is a vertical cylinder 407. On the outside of the vertical cylinder 407, a rotating shaft assembly 403 is provided. At one end of the rotating shaft assembly 403, a torsion spring 402 is provided. At the front end of the rotating shaft assembly 403, a receiving groove plate 406 is provided. A clamping plate 405 is clamped on the outside of the receiving groove plate 406. At one end of the clamping plate 405, a receiving frame 404 is provided. Inside the receiving frame 404, a material guiding hole 408 is provided. A rotating structure is formed between the rotating shaft assembly 403 and the receiving groove plate 406. Materials are introduced into the inside of the tank bottom 3. Then the materials first come into contact with the receiving frame 404 at the top of the tank ring 401. The material guiding hole 408 inside the receiving frame 404 helps to export some of the materials. The remaining materials squeeze the outside of the receiving frame 404. After the clamping plate 405 at one end of the receiving frame 404 is clamped with the receiving groove plate 406, the receiving frame 404 drives the receiving groove plate 406 and the clamping plate 405 to move downward. At the same time, the torsion spring 402 and the rotating shaft assembly 403 clamped on the outside of the vertical cylinder 407 help the receiving frame 404 to reduce the amplitude of the downward turning movement:

[0034] Among them, the following effects and novel technologies are brought:

[0035] Material diversion and introduction system: A unique material introduction mechanism is designed, including components such as a receiving frame 404, a material guiding hole 408, a clamping plate 405 and a receiving groove plate 406. This system can effectively control the speed and distribution of materials entering the fermenter, avoiding problems that may be caused by the direct and rapid fall of materials into the tank bottom 3.

[0036] Automatic adjustment mechanism: Through the cooperation of the rotating shaft assembly 403 and the torsion spring 402, the automatic downward movement and turning function of the receiving frame 404 are realized. This design can automatically adjust the downward speed and amplitude according to the weight of the materials to ensure the uniform distribution of the materials.

[0037] Buffer and shock absorption effect: The use of the torsion spring 402 not only controls the turning speed of the receiving frame 404, but also plays a role in buffering and shock absorption, which can reduce the impact on the equipment when the materials fall and extend the service life of the equipment.

[0038] Multi-stage diversion: The materials are first preliminarily diverted through the material guiding hole 408 on the receiving frame 404, and then secondary diversion is realized through the turning of the receiving frame 404. This multi-stage diversion design helps the materials to be more evenly distributed in the fermenter.

[0039] Modular design: The auxiliary structure 4 is composed of multiple components and is connected by clamping and other methods, which is convenient for assembly and maintenance. For example, the clamping design of the clamping plate 405 and the receiving groove plate 406, and the fixed connection between the receiving frame 404 and the clamping plate 405, etc.

[0040] Anti-loosening structure: The fixed connection design between the material storage frame 404 and the clamping plate 405 can prevent loosening when bearing a large amount of materials, improving the stability and reliability of the equipment.

[0041] Precise control: By adjusting the parameters of the torsion spring 402, the flipping speed and amplitude of the material storage frame 404 can be precisely controlled, thus achieving precise control of the material feeding speed.

[0042] Strong adaptability: This design can adapt to materials with different weights and properties. Through the automatic adjustment mechanism, it ensures uniform distribution of materials and is suitable for the production requirements of various biological fertilizers.

[0043] Improve fermentation efficiency: By controlling the uniform distribution of materials, the efficiency of the fermentation process and the consistency of product quality can be improved.

[0044] Easy to clean and maintain: The modular design makes the cleaning and maintenance of the equipment simpler, which is conducive to maintaining good sanitary conditions.

[0045] The novelty of this design lies in its combination of multiple functions such as mechanical automatic adjustment, multi-stage diversion, and buffer shock absorption, creating an efficient, reliable, and easy-to-maintain biological fertilizer fermentation system. This not only improves production efficiency, helps to improve product quality, but also reduces equipment maintenance costs and operation difficulties.

[0046] Such as Figures 1-11 As shown in the figure, a fermentation tank for producing biological fertilizers, the compressive structure 5 includes an embedded conical cylinder 501, a bottom shaft 502, a material storage conical cylinder 503, an outer wrapping piece 504 and a compression spring assembly 505. The embedded conical cylinder 501 is embedded on the inner side of the bottom inner cavity 6. The material storage conical cylinder 503 is vertically embedded on the inner side of the embedded conical cylinder 501. The bottom end of the material storage conical cylinder 503 is provided with a bottom shaft 502. The bottom end of the bottom shaft 502 is provided with a compression spring assembly 505. The top end of the embedded conical cylinder 501 is adhered with an outer wrapping piece 504. The material of the outer wrapping piece 504 is a flexible material. When the material descending speed slows down, the material storage conical cylinder 503 gradually receives the materials exported from the material guiding hole 408 and the tank ring 401. After the material storage conical cylinder 503 receives the materials, it starts to descend, and the outer wrapping piece 504 folds after following the descent of the material storage conical cylinder 503. The bottom shaft 502 at the bottom end of the material storage conical cylinder 503 gradually contacts the bottom end of the embedded conical cylinder 501. At the same time, the compression spring assembly 505 slows down the descending speed of the material storage conical cylinder 503:

[0047] Among them, the following effects and novel technologies are brought:

[0048] Hierarchical buffer system: Through the combination of the embedded conical cylinder 501, the material storage conical cylinder 503, the bottom shaft 502 and the compression spring assembly 505, a multi-stage buffer system is formed. This design can effectively slow down the descending speed of materials and prevent uneven distribution caused by rapid material accumulation.

[0049] Adaptive capacity adjustment: The receiving conical cylinder 503 can move up and down inside the nested conical cylinder 501, automatically adjusting the capacity according to the weight and quantity of the material. This design enables the fermenter to adapt to different batches and quantities of material input.

[0050] Flexible closed structure: The outer wrapping piece 504 is made of flexible material and can fold along with the descent of the receiving conical cylinder 503. This design not only ensures the enclosure of the material but also does not affect the movement of the receiving conical cylinder 503, while preventing material spillage.

[0051] Precise control of the descent speed: The design of the bottom shaft 502 and the compression spring assembly 505 can precisely control the descent speed of the receiving conical cylinder 503. This design ensures that the material accumulates at an appropriate speed, facilitating the formation of a uniform material layer.

[0052] Center alignment design: The center point of the receiving conical cylinder 503 is on the same straight line as the center of the tank ring 401. This design ensures the uniform introduction of the material and avoids uneven distribution caused by eccentricity.

[0053] Anti-blocking structure: The conical design of the receiving conical cylinder 503 and the nested conical cylinder 501 helps prevent material blockage, maintaining good material fluidity even in high humidity environments.

[0054] Shock absorption protection: The entire compressive structure 5 actually also functions as shock absorption, protecting the bottom of the fermenter from material impact and extending the service life of the equipment.

[0055] Convenient for cleaning and maintenance: The nested design allows each component to be easily disassembled for cleaning, facilitating the maintenance of good hygienic conditions.

[0056] Improve fermentation efficiency: By controlling the uniform distribution and accumulation speed of the material, better fermentation conditions can be created, improving the production efficiency and quality of bio-fertilizer.

[0057] Strong adaptability: This design can adapt to materials with different densities and humidities, enabling the fermenter to be used in the production of various types of bio-fertilizer.

[0058] Energy conservation and environmental protection: By optimizing the material distribution and accumulation process, energy consumption can be reduced and resource utilization efficiency can be improved.

[0059] The novelty of this design lies in integrating the principles of mechanical engineering, materials science, and bioengineering to create a new material handling system. It not only solves the problems of material input and distribution in traditional fermenters but also improves the efficiency and controllability of the entire production process. This design is of great significance for enhancing the production quality and efficiency of bio-fertilizer and also provides innovative ideas for other types of fermentation or reaction equipment.

[0060] Working principle: When using the fermenter for producing biological fertilizer, first open the top cover 1, then import the materials into the interior of the tank bottom 3. Then the materials first come into contact with the receiving frame 404 at the top of the tank ring 401. The material guiding holes 408 inside the receiving frame 404 help to export some of the materials, and the remaining materials squeeze the outside of the receiving frame 404. After the clamping plate 405 at one end of the receiving frame 404 is engaged with the receiving groove plate 406, the receiving frame 404 drives the receiving groove plate 406 and the clamping plate 405 to move downward. At the same time, the torsion spring 402 stuck on the outside of the vertical cylinder 407 and the rotating shaft assembly 403 help the receiving frame 404 to reduce the amplitude of the downward flipping movement. When the descending speed of the materials slows down, the conical barrel 503 gradually receives the materials exported from the material guiding holes 408 and the tank ring 401. After receiving the materials, the conical barrel 503 starts to descend, and the outer wrapping piece 504 folds after following the conical barrel 503 to descend. The bottom shaft 502 at the bottom end of the conical barrel 503 gradually contacts the bottom end of the embedded conical barrel 501. At the same time, the compression spring assembly 505 slows down the descending speed of the conical barrel 503. This is the working principle of the fermenter for producing biological fertilizer.

[0061] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
