Description

Technical Field

[0001] The invention belongs to the technical field of microbial fermentation equipment, in particular to a device for fermenting a saline-alkali soil remediation bacterial agent. Background Art

[0002] The restoration of saline-alkali soil is one of the urgent problems to be solved in my country. In my country, the land area affected by salinization accounts for a considerable proportion of the per capita arable land area, which not only limits the planting of crops, but also seriously affects the productivity of the land. With the continuous advancement of the technology of microbial treatment and restoration of saline-alkali soil, and the remarkable results achieved in the microbial treatment and restoration of saline-alkali land experiments in many regions, the use of microbial agents to repair saline-alkali soil has become an emerging and important direction for saline-alkali land management.

[0003] When using microbial agents to repair saline-alkali soil, a large amount of microbial agents are required to grow and reproduce in the saline-alkali soil. In experimental studies, it was found that inoculating the microbial agents in decomposed organic fertilizers, pre-fermenting them in a fermentation device, and then applying the microbial agents and organic fertilizers to the saline-alkali soil can effectively promote the rapid growth and reproduction of microbial species in the saline-alkali soil. This pre-fermentation process not only improves the activity of the microbial agents, but also enhances their adaptability and tolerance in saline-alkali soil. In conventional fermentation, organic matter is usually first fermented. It is placed in a fermentation device for fermentation and composting. When the composted organic matter is cooled to a suitable temperature, the microbial strains are inoculated into the organic matter, and then a secondary fermentation is carried out in the fermentation device. The secondary fermentation causes the inoculated microorganisms to grow and multiply in the organic matter, thereby greatly increasing the number of microbial strains, which is convenient for the later restoration of saline-alkali land. However, after the organic matter is fermented, its texture is relatively loose and its water content is high, so it is not easy for the microbial strains to spread quickly in the composted organic matter, which in turn affects the rapid growth of the number of microbial strains during pre-fermentation.

[0004] The related technology discloses a solid-state fermentation liquid strain inoculation device, and the application number is CN2020107931211. In this scheme, before the fermentation tank is cooled to a certain temperature, the fermentation tank is placed inside the device. After the cooling is completed, the microbial strain is added into the fermentation tank without transfer. The fermentation tank is directly shaken to speed up the mixing speed, which is not easy to contact other bacteria, saving time and effort. However, in the rapid propagation of experimental microbial agents in decomposed organic matter using the scheme, it was found that, on the one hand, due to the high water content of the decomposed organic matter itself and the long-term accumulation state, it is difficult to disperse the microbial agent inside it. On the other hand, when breeding microbial strains, the content of microbial agents is less than that of organic fertilizer. Therefore, during the breeding process, the initial dispersion degree of the microbial agent has a great influence on its proliferation rate.

[0005] In view of this, the present invention proposes a saline-alkali soil remediation bacterial agent fermentation device to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 8 As shown, a saline-alkali soil remediation bacterial agent fermentation device according to the present invention comprises a fermentation tank body 1, wherein the fermentation tank body 1 is used to provide a sealed fermentation space;

[0038] It also includes a dispersed inoculation component, which is installed in the fermentation tank body 1 and is used to disperse and inoculate the microbial agent in the organic matter;

[0039] The dispersed inoculation assembly includes an inoculation box 2, a puncture needle 27 and a push plate 26;

[0040] The fermentation tank body 1 is provided with a through groove 21, and an inoculation box 2 is fixedly installed on the fermentation tank body 1, and the inoculation box 2 extends into the through groove 21;

[0041] The two sides of the through groove 21 are provided with puncture grooves 22, the puncture grooves 22 are connected to the inner cavity of the inoculation box 2, the puncture needle 27 passes through the puncture grooves 22 to the inside of the fermentation tank body 1, and a connecting rod 23 is installed together at one end of the multiple puncture needles 27 away from the fermentation tank body 1;

[0042] A support frame 24 is installed outside the fermentation tank body 1, and the fermentation tank body 1 is installed on the support frame 24. A rotating shaft 25 is rotatably installed inside the fermentation tank body 1, and the rotating shaft 25 extends to the outside of the fermentation tank body 1. The rotating shaft 25 is fixedly installed with evenly distributed push plates 26 along the circumferential direction;

[0043] In the process of propagation of microbial agents, organic matter serving as culture medium is placed in the fermentation tank body 1 for fermentation and composting. After the organic matter is decomposed, in order to enhance the uniformity of dispersion of the microbial agents in the organic matter, the present invention uses a dispersed inoculation component and a puncture needle 27 with the microbial agents adhered to it into the organic matter by puncture, thereby enhancing the convenience of inoculation and dispersion of the microbial agents.

[0044] Specifically, when inoculating microbial strains, the microbial agent is first processed (liquid microbial agent or powdered microbial agent is mixed with water in proportion) to facilitate the microorganisms to be evenly adhered to the puncture needle 27, and then the inoculation box 2 is opened, and the microbial agent mixed with water is poured into the inoculation box 2, and the puncture needle 27 extending into the inoculation box 2 is in contact with the microbial agent liquid, so that the microbial agent adheres to the puncture needle 27. When the staff manually pushes the connecting rod 23, the evenly distributed puncture needles 27 installed on the connecting rod 23 are pushed along the puncture groove. 22 is inserted into the fermentation tank body 1. During the insertion process, friction is generated between the puncture needle 27 and the organic matter, thereby transferring the microbial agent on the puncture needle 27 to the organic matter. After a single insertion, the rotating shaft 25 is manually pushed to rotate, and the rotating shaft 25 drives the push plate 26 to rotate, thereby rotating the organic matter inside the fermentation tank body 1, so that relative rotation is generated between the organic matter and the inoculation box 2, and then the puncture needle 27 is pushed again for insertion. Repeating the operation, the microbial agent can be inoculated into the organic matter during multiple insertions of the puncture needle 27.

[0045] The present invention sets a dispersed inoculation component, and through the rotation of the organic matter in the fermentation tank body 1 and the repeated puncture of the puncture needle 27, the microbial agent adheres to the puncture needle 27 and is then transferred to the puncture holes uniformly distributed in the organic matter. On the one hand, during the entire inoculation process, not only is it unnecessary to open the fermentation tank body 1, but the puncture needle 27 is easy to insert into the organic matter, so that the microbial agent can be extended into the stacked organic matter more conveniently. On the other hand, during the multiple punctures, the puncture needle 27 forms a plurality of puncture holes in the organic matter. Although some of the puncture holes are destroyed during the rotation of the organic matter, the gaps in the stacked organic matter are still increased, so that the microbial agent can be exchanged with the outside air more conveniently during fermentation, and the microbial agent can be diffused in the organic matter more conveniently.

[0046] As a preferred embodiment of the present invention, the fermentation tank body 1 is hinged by an upper end and a lower end, and the fermentation tank body 1 is detachably fixedly connected to the side away from the hinged end by a buckle 11. The fermentation tank body 1 is rotatably mounted on a support frame 24, and a deflection groove 3 is provided on the support frame 24. A limit block 31 is fixedly installed on the bottom of the fermentation tank body 1, and the limit block 31 extends into the deflection groove 3.

[0047] Before and after the fermentation of organic matter or microbial inoculants, when the staff needs to load organic matter or unload organic matter carrying microbial inoculants, the staff only needs to operate the buckle 11 to realize the closing and opening of the fermentation tank body 1, and then manually push the inoculation box 2 or the fermentation tank body 1 to make the fermentation tank body 1 rotate on the support frame 24, and at the same time drive the limit block 31 to rotate in the deflection groove 3, and by adjusting the position of the opening of the fermentation tank body 1 and coordinating the rotation of the rotating shaft 25 and the push plate 26, the loading or unloading of organic matter can be effectively enhanced. It should be noted that in the invention, the support frame 24 is rotatably installed with rollers at the contact part with the fermentation tank body 1, and the rolling of the rollers is utilized to effectively enhance the rotation convenience of the fermentation tank body 1 on the support frame 24.

[0048] As a preferred embodiment of the present invention, a liquid storage tank 4 is provided on the limit block 31, and the liquid storage tank 4 is connected to the inner cavity of the fermentation tank body 1. A filter cloth 41 is fixedly installed at the connection between the liquid storage tank 4 and the fermentation tank body 1. A liquid extraction tube 42 is fixedly installed on the limit block 31, and the liquid extraction tube 42 extends to the inside of the inoculation box 2. A pressing bag 43 is fixedly installed in the middle of the liquid extraction tube 42, and one-way valves are installed at both ends of the liquid extraction tube 42.

[0049] During the fermentation process of microbial agents or organic matter, liquid will be produced. When filling the microbial agents, the staff manually presses the pressing capsule 43, causing the pressing capsule 43 to contract and expand regularly. The pressure changes caused by the contraction and expansion of the pressing capsule 43 are used in conjunction with the liquid extraction tube 42 equipped with a one-way valve, so that the liquid flowing into the liquid storage tank 4 is transported to the inside of the inoculation box 2. Then the staff can directly pour the microbial agent into the liquid without mixing the microbial agent with water. At the same time, during the repeated rotation and puncture process, the staff can manually squeeze the pressing capsule 43 and use the changes in the pressing capsule 43 to continuously extract the liquid. Then the liquid passes through the gap between the puncture needle 27 and the puncture groove 22 and flows into the fermentation tank again, and flows into the liquid storage tank 4 under the action of gravity, thereby realizing the circulation of the liquid. The circulation of the liquid is used to entrain the microbial agent, thereby accelerating the diffusion rate of the microbial agent in the organic matter.

[0050] As a preferred embodiment of the present invention, the through groove 21 and the inoculation box 2 are both located above the axis of the fermentation tank body 1, the puncture needle 27 is arranged obliquely, and the lowest end of the puncture needle 27 faces the axis of the fermentation tank body 1, and a sealing ring 44 is fixedly installed on the inner wall of the puncture groove 22, and the surface of the puncture needle 27 is sandblasted.

[0051] Since liquid materials are stored in the inoculation box 2 and a puncture groove 22 is provided on the inoculation box 2, in order to prevent the liquid in the puncture box from flowing to the outside, the inoculation box 2 is installed above the horizontal plane where the axis of the fermentation tank body 1 is located. Not only can the liquid only flow into the fermentation tank body 1 through the puncture groove 22 on the inoculation box 2, but also in the process of the puncture needle 27 moving back and forth, the gravity is used to reduce the tendency of the liquid to flow to the outside following the puncture needle 27. The presence of the sealing ring 44 further reduces the gap between the puncture needle 27 and the puncture groove 22. Combined with the sandblasting treatment on the surface of the puncture needle 27, the surface of the puncture needle 27 is rough. Therefore, when the puncture needle 27 moves, it can not only make the liquid seep into the fermentation tank body 1, but also reduce the probability of solid organic matter in the fermentation tank body 1 following the puncture needle 27 to move into the inoculation box 2.

[0052] As a preferred embodiment of the present invention, the angle between the inoculation box 2 and the limit block 31 is greater than ninety degrees, one side of the deflection groove 3 is aligned with the lowest end of the fermentation tank body 1, and in the initial state, under the action of the gravity of the inoculation box 2 and the limiting action of the deflection groove 3, the limit block 31 is located at the bottom of the fermentation tank body 1.

[0053] The angle between the inoculation box 2 and the limit block 31 and the position of the deflection groove 3 are set so that when there is no external force, under the action of gravity balance, the limit block 31 can stay at the bottom of the fermentation tank body 1, thereby facilitating the liquid in the fermentation tank body 1 to flow into the liquid storage tank 4.

[0054] As a preferred embodiment of the present invention, it also includes an alternating drive assembly, which is installed on the fermentation tank body 1, and is used to alternately drive the puncture needle 27 and the rotating shaft 25, and the alternating drive assembly includes a drive motor 5, a multi-stage connecting rod 51, a single-toothed special-shaped wheel 52 and a toggle wheel 53;

[0055] The drive motor 5 is fixedly mounted at both ends of the fermentation tank body 1, and a single-toothed special-shaped wheel 52 and a multi-stage connecting rod 51 are fixedly mounted at the output end of the drive motor 5. The multi-stage connecting rod 51 is composed of two mutually hinged rods, and the end of the multi-stage connecting rod 51 away from the drive motor 5 is hingedly connected to the connecting rod 23;

[0056] A toggle wheel 53 is fixedly mounted on both ends of the rotating shaft 25 , and the toggle wheel 53 is meshedly connected with the single-tooth special-shaped wheel 52 .

[0057] The manual control of the dispersed inoculation assembly is not only time-consuming and laborious, but also has poor uniformity in the rotation angle of the organic matter. Therefore, by setting an alternating drive assembly, the convenience of using the fermentation device can be enhanced. Specifically, when the microbial inoculant is punctured and inoculated, the drive motor 5 is started. When the drive motor 5 rotates, it drives the single-toothed special-shaped wheel 52 and the multi-stage connecting rod 51 to rotate, wherein the single-toothed special-shaped wheel 52 is a gear with only one tooth. The single-toothed special-shaped wheel 52 pushes the toggle wheel 53 meshing with it once every rotation, and the multi-stage connecting rod 51 also rotates. After one rotation, the multi-stage connecting rod 51 is composed of two rods hinged together, and the ends of the two rods away from the hinge point are respectively connected to the output end of the drive motor 5 and the connecting rod 23. Under the transmission action of the multi-stage connecting rod 51, the connecting rod 23 and the puncture needle 27 make regular reciprocating motion, so that the reciprocating motion of the connecting rod 23 and the rotation of the fluctuation wheel are alternately performed, thereby making the rotation of the organic matter and the insertion of the puncture needle 27 alternately performed, which not only effectively enhances the convenience of microbial inoculation, but also makes the rotation angle of the rotating shaft 25 more stable, thereby facilitating the uniform inoculation of the microbial agent in the organic matter.

[0058] As a preferred embodiment of the present invention, the pressing capsule 43 is fixedly mounted on the inoculation box 2 , and the pressing capsule 43 is located on the movement path of the connecting rod 23 .

[0059] The pressing capsule 43 is installed on the movement path of the connecting rod 23, so that the pressing capsule 43 can be automatically pressed during the movement of the connecting rod 23, further enhancing the convenience of use of the device.

[0060] As a preferred embodiment of the present invention, the puncture needle 27 is hollow, and the surface of the puncture needle 27 is provided with evenly distributed impact holes 54 , and a plurality of the impact holes 54 are connected through the inner cavity of the puncture needle 27 .

[0061] When continuously extracting and transporting liquid, in order to facilitate the liquid to flow back into the fermentation tank body 1, an impact hole 54 is opened on the puncture needle 27, so that the liquid can diffuse toward the middle of the organic matter along the impact hole 54 and the inner cavity of the puncture needle 27 under the action of gravity, thereby enhancing the effect of liquid circulation.

[0062] As a preferred embodiment of the present invention, an isolation sleeve 55 is fixedly installed between the connecting rod 23 and the inoculation box 2 . The isolation sleeve 55 corresponds to the puncture needle 27 one by one. The puncture needle 27 is located inside the isolation sleeve 55 .

[0063] The provision of the isolation sleeve 55 further reduces the tendency of the liquid to flow to the outside along the connecting rod 23 .

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
