Description

Technical Field

[0001] The present invention relates to the field of microbial reagent fermentation equipment, and particularly to a fermentation equipment for microbial reagents for improving severely saline-alkali soil. Background Art

[0002] Soil salinization is one of the important environmental problems faced globally. Especially for severely saline-alkali soil, its high salt content seriously affects the growth and development of plants, leading to a significant decline in crop yields and damage to the ecosystem. Severely saline-alkali soil will cause damage to the soil structure, with poor air permeability and water permeability, making it difficult for plant roots to grow and absorb nutrients normally. At the same time, it will also affect the community structure and function of microorganisms in the soil, further deteriorating the soil ecological environment. Using microbial reagents to improve severely saline-alkali soil is an environmentally friendly method with long-term effects. Microorganisms can improve soil properties through various mechanisms. For example, some salt-tolerant microorganisms can secrete extracellular polysaccharides and other substances, increasing the aggregation of soil particles, improving the soil structure, and enhancing the water and fertilizer retention capacity of the soil. The activities of microorganisms can also promote the decomposition and transformation of organic matter in the soil, increasing soil fertility and providing a good soil environment for plant growth.

[0003] When the existing fermentation equipment is working, the material is first introduced into the fermentation tank through the feed pipe. The driving component drives the rotating pipe and the rotating shaft to rotate, and in cooperation with the auxiliary component, the rotation of the rotating box and the control block can disperse the material to both sides, and stirring is carried out through this shunting method.

[0004] However, the stirring of this equipment is in one direction. Stirring in one direction for a long time cannot cross-mix and is prone to generating mixing dead corners. Stirring in one direction causes insufficient mixing of organic matter and fermentation strains, resulting in a reduction in fermentation efficiency or even fermentation failure.

[0023] The discharging mechanism 4 includes a first opening and closing shaft 401 and a second opening and closing shaft 404, the first opening and closing shaft 401 and the second opening and closing shaft 404 are both rotatably installed on the inner wall of the tank body 1, both ends of the first opening and closing shaft 401 and the second opening and closing shaft 404 penetrate through the inner wall of the tank body 1 and extend to the outside, one ends of the first opening and closing shaft 401 and the second opening and closing shaft 404 located outside the tank body 1 are respectively fixedly installed with a first gear 403 and a second gear 406, the first gear 403 is engaged with the second gear 406, a first opening and closing plate 402 is fixedly installed on the surface of the first opening and closing shaft 401, a second opening and closing plate 405 is fixedly installed on the surface of the second opening and closing shaft 404, and a handle 407 is fixedly installed at one end of the first opening and closing shaft 401 located outside the tank body 1.

[0024] During actual use, the tank body 1 is a fermentation tank body; The exhaust hole 10 is a one-way exhaust structure for discharging fermentation gas; The fan blades 307 are provided in a plurality, with a minimum of six; The rotating disk 302 rotates clockwise, the stirring gear 305 on the outside rotates clockwise, and the stirring gear 305 on the inside rotates counterclockwise; The four inner stirring gears 305 form a group, and the four outer stirring gears 305 form a group.

[0025] The working principle of the fermentation equipment of the microbial reagent for improving severely salinized soil provided by the present invention is as follows: First, the left and right feed ports 11 are opened manually to put corresponding fermentation bacteria and organic matter in proportion, and the two feed ports 11 are closed after the putting is completed.

[0026] Then, the motor 301 is started to drive the rotating disk 302 to rotate, and the rotating disk 302 drives the stirring gear 305 to rotate through the stirring shaft 306. At this time, the fixed gear ring 304 is respectively meshed with the eight stirring gears 305 on the inner and outer sides. The stirring shaft 306 rotates while following the rotating disk 302 to revolve around the motor 301 and drives the fan blades 307 to rotate. Since the meshing directions of the four stirring gears 305 on the outer side and the four stirring gears 305 on the inner side are opposite, the rotation directions of the four fan blades 307 on the inner and outer sides are also opposite. Therefore, the two groups of fan blades 307 on the inner and outer sides rotate in opposite directions to stir the fermented bacteria and organic matter to fully mix. While rotating, the fermentation agent is subjected to centrifugal force and discharged into the fermentation raw materials through the capillaries on the fan blades 307 to promote the reaction. When ventilation is needed, the oxygen supply mechanism 8 is opened to ventilate through the ventilation hole 14. After fermentation for a certain period of time, the gas generated by the fermented bacteria and organic matter is discharged from the exhaust hole 10. After ventilation is completed, the stirring work continues.

[0027] Then, after the fermentation is completed, the motor 301 is turned off, and the handle 407 is manually rotated to the right. At this time, the first gear 403 engages with the second gear 406 to drive the first opening and closing plate 402 and the second opening and closing plate 405 to rotate in opposite directions respectively. After the fermentation is completed, the microbial reagent falls from the two plates into the discharge port 12 below.

[0028] Finally, the microbial reagent after fermentation is obtained by manually opening the discharge port 12.

[0029] Compared with the related art, the fermentation equipment for microbial reagents for improving severely salinized soil provided by the present invention has the following beneficial effects: By setting the teeth on the inner and outer sides of the toothed ring 304 to mesh with two sets of stirring gears 305 respectively, the fan blades 307 are driven to rotate in two directions while revolving, forming a strong convective shear force, breaking the material stratification and eliminating the stirring dead angle, ensuring that the fermentation strains are in full contact with the organic matter. By setting the handle 407 to open the first opening and closing plate 402 and the second opening and closing plate 405 oppositely to form a discharge channel, avoiding material adhesion or blockage. By setting the exhaust holes 10 to discharge the fermentation gas to avoid excessive air pressure inside the tank body 1.

[0030] Second Embodiment:

[0031] Please refer to Figures 7 - 10 , based on a fermentation device for a microbial reagent for improving severely saline-alkali soil provided in the first embodiment of the present application, the second embodiment of the present application proposes another fermentation device for a microbial reagent for improving severely saline-alkali soil. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0032] Specifically, the difference of a fermentation device for a microbial reagent for improving severely saline-alkali soil provided in the second embodiment of the present application is that the connection mechanism 2 includes a cross fixing frame 201, the cross fixing frame 201 is fixedly installed on the inner wall of the tank body 1, a hydraulic cylinder 202 is fixedly installed at the bottom of the cross fixing frame 201, and the output shaft of the hydraulic cylinder 202 is fixedly connected to the top of the motor 301.

[0033] The oxygen supply mechanism 8 includes an oxygen tank 801, the oxygen tank 801 is placed on the ground, the oxygen tank 801 is communicated with the tank body 1 through an oxygen supply pipe 802, the oxygen supply pipe 802 extends into the interior of the tank body 1, and a solenoid valve 803 is installed on the surface of the oxygen supply pipe 802 inside the tank body 1.

[0034] A start-stop plate 9 is fixedly installed on the top of the rotating disk 302, and the start-stop plate 9 is adaptively installed with the solenoid valve 803.

[0035] A space for storing the fermentation agent is provided inside the stirring shaft 306 and the fan blade 307, and a feeding port 15 is provided at the top end of the stirring shaft 306.

[0036] At the top of the cross fixing frame 201, a feeding mechanism 5 is fixedly installed. The feeding mechanism 5 includes a feeding box 501 which is fixedly installed at the top of the cross fixing frame 201. A feeding pipe 502 communicates with the top of the feeding box 501. The feeding pipe 502 penetrates through the top cover of the tank body 1 and extends to the outside. Eight discharging pipes 503 communicate with the bottom of the feeding box 501. Spherical balls 504 are placed inside the eight discharging pipes 503, and the spherical balls 504 are used to close the discharging of the discharging pipes 503.

[0037] The stirring shaft 306 is connected with a feeding pipe 6 through the feeding port 15, and the feeding pipe 6 is adaptively installed with the discharging pipe 503.

[0038] During actual use, the bottom of the discharging pipe 503 is funnel-shaped; The eight discharging pipes 503 do not conflict with the cross fixing frame 201; The diameter of the spherical ball 504 is smaller than the diameter of the discharging pipe 503; In this embodiment, the connecting column 303 is raised to avoid conflict with the feeding pipe 6.

[0039] The working principle of a fermentation device for microbial reagents for improving severely saline-alkali soil provided in this embodiment is as follows: First, after stirring for a certain time, when ventilation is required, the hydraulic cylinder 202 is started to drive the rotating disk 302 to rise through the motor 301. At this time, the rotating disk 302 is separated from the fermentation raw materials, and the efficiency of oxygen exchange through the ventilation holes 14 is improved. At the same time, after the rising of the rotating disk 302 ends, the start-stop plate 9 contacts the solenoid valve 803 to open the oxygen supply pipe 802, and the oxygen in the oxygen tank 801 is input into the interior of the tank body 1.

[0040] Then, after the rising of the rotating disk 302 ends, it also drives the feeding pipe 6 to rise. The feeding pipe 6 extends into the interior of the discharging pipe 503, and the feeding pipe 6 pushes up the spherical ball 504. At this time, the fermentation agent pre-stored in the interior of the feeding box 501 flows into the space for storing the fermentation agent in the stirring shaft 306 and the fan blades 307 through the feeding pipe 6.

[0041] Finally, after feeding and ventilation are completed, while the feeding pipe 6 descends, the spherical ball 504 resets to block the outlet of the discharging pipe 503. At the same time, the solenoid valve 803 is closed, and oxygen supply and ventilation also end. When the fermentation agent in the feeding box 501 is used up after being replenished multiple times, manual feeding can be carried out from the outside through the feeding pipe 502.

[0042] Compared with the related technology, a fermentation device for microbial reagents for improving severely saline-alkali soil provided in this embodiment has the following beneficial effects: By setting up a rotary disk 302 lifting mechanism where the hydraulic cylinder 202 is linked with the motor 301, after the rotary disk 302 rises and disengages from the raw material layer, the oxygen exchange efficiency of the air vents 14 is improved. Meanwhile, the solenoid valve 803 is triggered to automatically open the oxygen supply pipe 802. By setting up a self-sealing valve structure where the feeding pipe 6 is linked with the spherical ball 504, pollution-free replenishment of the fermentation agent is achieved. When the rotary disk 302 is lifted, the feeding pipe 6 simultaneously pushes open the spherical ball 504, enabling the pre-stored fermentation agent in the feeding tank 501 to be accurately injected along the internal channel of the stirring shaft 306. After the spherical ball 504 resets, it automatically seals the discharge port, and replenishment is carried out in cooperation with the external manual feeding interface.

[0043] Third Embodiment:

[0044] Please refer to Figure 7 and Figure 11 Based on a fermentation device for a microbial reagent for improving severely saline-alkali soil provided in the first embodiment of the present application, the third embodiment of the present application proposes another fermentation device for a microbial reagent for improving severely saline-alkali soil. The third embodiment is merely a preferred mode of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0045] Specifically, the difference of a fermentation device for a microbial reagent for improving severely saline-alkali soil provided in the third embodiment of the present application is that storage mechanisms 7 are symmetrically and fixedly installed on the inner wall of the tank body 1. The storage mechanism 7 includes a storage tank 701, the storage tank 701 is fixedly installed on the inner wall of the tank body 1 through a support plate, a feeding pipe 702 communicates with the bottom of the storage tank 701, a valve 703 communicates with the surface of the feeding pipe 702, a valve disk 704 is fixedly connected to the switch shaft of the valve 703, the valve disk 704 is rotationally connected with a connecting rod 705 through a cam, one end of the connecting rod 705 is rotationally connected with a driving plate 706, and a feeding pipe 707 communicates with the top of the storage tank 701.

[0046] A through hole adapted to the feeding pipe 702 is opened on the rotary disk 302, and the feeding pipe 707 penetrates through the top cover of the tank body 1 and extends to the outside for raw material input.

[0047] During actual use, the left storage mechanism 7 is used to place salt, and the right storage mechanism 7 is used to place the protective agent; The rotary disk 302 is provided with a horizontal groove adapted to the driving plate 706 for the horizontal movement of the driving plate 706.

[0048] The working principle of a fermentation device for a microbial reagent for improving severely saline-alkali soil provided in this embodiment is as follows: First, during the upward movement of the rotating disk 302, the rotating disk 302 pushes the driving plate 706 upward. At this time, the driving plate 706 drives the valve disk 704 to rotate through the connecting rod 705. The rotation of the valve disk 704 drives the valve 703 to open. At this time, the two storage mechanisms 7 discharge salt and protective agent through the feeding pipes 702 respectively and fall onto the fermentation raw materials below. After the discharging is completed, the driving plate 706 automatically closes the valve 703 under the action of gravity.

[0049] During the process of improving the salt tolerance of the microbial inoculant, while gradually increasing the salt concentration (0% - 5% - 10%), a longer ventilation time is also required. Therefore, when the rotating disk 302 rises for ventilation, the salt and the protective agent are also put in twice. The second ventilation time is longer, so the amount of the second input is also larger. By this way, the salt tolerance is gradually improved, and the microbial reagent suitable for the improvement of severely saline-alkali soil is screened out.

[0050] Finally, before the next fermentation operation, the salt and the protective agent can be replenished through the two feeding pipes 707 respectively.

[0051] Compared with the related technology, the fermentation equipment for the microbial reagent for improving severely saline-alkali soil provided by this embodiment has the following beneficial effects: Driven by the upward movement of the rotating disk 302, the driving plate 706 is driven to open the valve 703, realizing the automatic discharging of the storage mechanism 7, ensuring the synchronous feeding of salt and protective agent, improving the overall operation efficiency and automation degree. Combining the law of gradually increasing salt concentration and prolonging ventilation time, the feeding times and feeding amounts of salt and protective agent are accurately controlled in stages. The second ventilation time is long and the feeding amount is large, which conforms to the characteristics of microorganisms adapting to high-salt environments, can effectively promote the microbial inoculant to gradually adapt to different salt concentration environments, and can relieve the osmotic stress caused by the increase of salt concentration by supplementing the protective agent, maintaining the activity of the bacterial strain.

[0052] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
