Description

Technical Field

[0001] This utility model relates to the field of microbial agent production technology, specifically to a microbial agent production line. Background Technology

[0002] Microbial inoculants are biological agents containing beneficial microorganisms, primarily used to improve soil and crop environments, and enhance plant growth and stress resistance. These microorganisms can decompose organic matter, fix nitrogen, promote nutrient absorption, and inhibit harmful pathogens, thereby improving the efficiency and quality of agricultural production.

[0003] In the production process of existing microbial agents, fermentation is a crucial step that directly affects the quality and yield of the agent. While existing fermenters can meet production needs to a certain extent, there is still room for improvement in terms of fermentation efficiency, energy utilization, and ease of operation. Therefore, a fermenter for the production of microbial agents is needed. Based on this, Chinese Patent Publication No. CN219136750U discloses a fermenter for the production of microbial agents. This patented technology utilizes the coordinated use of a tank body, a cover, support legs, a discharge pipe, an annular fixing component, an electric telescopic rod, an annular movable component, a feed pipe, a rotating drum, a transmission mechanism, a motor, and a transverse stirring roller. The stirring mechanism moves to the outside of the tank body along with the cover, allowing for cleaning of the stirring mechanism from the outside of the tank body. This provides good visibility, facilitates cleaning, and enables quick and thorough cleaning. After cleaning, the cover is reset by the electric telescopic rod. The sealing gasket at the connection between the cover and the tank body ensures the airtightness of the tank during use.

[0004] However, as can be seen from the specification and drawings of the aforementioned patent technology, although the patent technology can improve the mixing effect of microbial agents in specific implementation, the oxygen content of the microbial agents at the bottom position is relatively low, which will affect the fermentation effect of the microbial agents at the bottom position. Therefore, there are still some shortcomings.

[0005] In conclusion, it is necessary to invent a microbial agent production line. Utility Model Content

[0006] To address this issue, the present invention provides a microbial inoculant production line to solve the problem that the microbial inoculant at the bottom has a relatively low oxygen content, which affects the fermentation effect of the microbial inoculant at the bottom.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a microbial agent production line, comprising a pretreatment tank, a storage tank, a fermentation tank, and a dryer, wherein the pretreatment tank, the storage tank, the fermentation tank, and the dryer are connected by pipelines and a conveying auger, the fermentation tank includes a tank body, a stirring component is provided inside the tank body, and an auxiliary fermentation component is also provided inside the tank body.

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figures 1-5 The present invention provides a microbial agent production line, including a pretreatment tank 100, a storage tank 200, a fermentation tank 300, and a dryer 400, wherein the pretreatment tank 100, the storage tank 200, the fermentation tank 300, and the dryer 400 are connected by pipelines and a conveying auger.

[0025] The fermenter 300 includes a tank body, and heating pipes are installed on the inner wall of the tank body to provide temperature for the fermentation of microbial agents. A vent is located at the top of the tank body to exhaust waste gas. A stirring component is installed inside the tank body, including a stirring motor 310. The stirring motor 310 is installed at the center of the top of the outer wall of the pretreatment tank 100. A main stirring rod 320 is rotatably connected to the upper and lower sides of the inner wall of the fermenter 300, below the stirring motor 310, via bearing seats. The bottom output end of the stirring motor 310 is fixedly connected to the top of the main stirring rod 320. Main stirring blades 321 are fixed to the outer side of the main stirring rod 320. Multiple main stirring blades 321 are evenly arranged in a strip array. When the stirring motor 310 is powered on, it drives the main stirring rod 320 to rotate. During rotation, the main stirring rod 320 can... The main stirring blade 321 is used to stir the microbial agent to be fermented. The outer wall of the main stirring rod 320 and between the main stirring blades 321 are rotatably connected to the auxiliary stirring rod 322. The side end of the auxiliary stirring rod 322 is connected to the side end of the outer wall of the main stirring rod 320 through the bearing seat. The end of the auxiliary stirring rod 322 away from the main stirring rod 320 is fixed with a roller 323. The inner wall side of the fermentation tank 300 and below the roller 323 is fixed with an arc-shaped track 324. The bottom end of the outer wall of the roller 323 is in contact with the top end of the outer wall of the arc-shaped track 324. When the main stirring rod 320 rotates, it can make the roller 323 rotate at the top of the arc-shaped track 324. When the roller 323 rotates, it can drive the auxiliary stirring rod 322 to rotate, so that the auxiliary stirring rod 322 stirs the microbial agent.

[0026] The tank also contains auxiliary fermentation components, including aeration discs 330. Two aeration discs 330 are located on both sides of the bottom inner wall of the fermentation tank 300. The air inlet end of each aeration disc 330 is fixedly connected to a hollow rod 331. The end of the hollow rod 331 furthest from the aeration disc 330 is rotatably connected to corresponding positions on both sides of the inner wall of the fermentation tank 300. A dynamic seal is provided at the connection point between the inner wall of the fermentation tank 300 and the hollow rod 331. The hollow rod 331 can drive the aeration discs 330 to rotate, thereby adjusting the air jet angle of the aeration discs 330. The end of the hollow rod 331 furthest from the aeration disc 330 passes through both sides of the outer wall of the fermentation tank 300 and is connected to an air inlet pipe 332 via a rotating sleeve. Drive motors 333 are fixed on both sides of the outer wall of the fermentation tank 300, below the hollow rods 331. The output end is connected to the outer wall of the hollow rod 331 via a pulley mechanism 334. The other end of the air inlet pipe 332 can be connected to an oxygen storage tank (existing technology, not shown in the figure). The oxygen storage tank can transport oxygen to the aeration disc 330 through the air inlet pipe 332 and the hollow rod 331. The aeration disc 330 can discharge oxygen in the form of bubbles. The aeration disc 330 has a built-in one-way valve to prevent backflow of microbial agents. At the same time, the drive motor 333 can be energized to drive the hollow rod 331 to rotate through the pulley mechanism 334. This allows the hollow rod 331 to adjust the angle of the aeration disc 330 in conjunction with the rotating sleeve shaft. The rotating sleeve shaft has a built-in bearing and a dynamic seal to ensure a sealing effect. The pulley mechanism 334 consists of two pulleys and a drive belt connecting the pulleys.

[0027] The auxiliary fermentation components also include a liquid pump 350, which is fixed to one side of the top of the outer wall of the fermenter 300. The pump 350's suction end is fixedly connected to a return suction pipe 351, the bottom end of which is connected to the bottom of the inner wall of the fermenter 300. When powered on, the pump 350 can extract the microbial agent at the bottom through the return suction pipe 351. The upper end of the outer wall of the return suction pipe 351 is also connected to a disinfectant inlet pipe 352 via a T-junction. The other end of the disinfectant inlet pipe 352 can be connected to a pump on a disinfectant storage tank, allowing the disinfectant inlet pipe 352 to deliver cleaning solution into the fermenter 300 for cleaning. An annular disc 353 is fixed above the inner wall of the fermenter 300. The liquid delivery end of the pump 350 is connected to the inlet of the annular disc 353 through a pipe. The bottom of the outer wall of the annular disc 353 is fixedly connected to a nozzle 354. The annular disc 353 can spray out microbial agents or cleaning liquid through the nozzles 354. The connection between the reflux pump pipe 351 and the disinfectant inlet pipe 352 is equipped with a solenoid valve for control. The pump 350 can exchange the microbial agents in the upper and lower layers of the fermenter 300 to avoid uneven fermentation due to insufficient oxygen contact in the upper layer of microbial agents. The reflux pump pipe 351 can be an insulated pipe.

[0028] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel.

[0029] First, the microbial agent to be produced can be pre-treated and stored in the pretreatment tank 100 and storage tank 200, and then transported to the fermentation tank 300 through pipelines. The stirring motor 310 can be powered to drive the main stirring rod 320 to rotate, so that the main stirring rod 320 can stir the microbial agent through the main stirring blade 321 and the auxiliary stirring rod 322, so that the fermentation is more complete. At the same time, the oxygen storage tank can deliver oxygen to the aeration plate 330 through the air inlet pipe 332 and the hollow rod 331. The aeration plate 330 can spray oxygen in the form of bubbles, thus providing oxygen to the fermenting microbial agent.

[0030] After a period of time, the pump 350 can be powered on, and the solenoid valves on the upper and lower sides of the return pump pipe 351 can be opened. The pump 350 can then draw the microbial agent at the bottom of the fermenter 300 through the return pump pipe 351 and transport it to the annular disc 353. The annular disc 353 will spray the microbial agent out through the nozzle 354. This will change the position of the microbial agent at the upper and lower sides inside the fermenter 300, ensuring that the microbial agent in the fermenter 300 can be fully fermented. After fermentation is completed, the personnel can open the discharge valve at the bottom of the fermenter 300 to discharge the microbial agent into the dryer 400 for subsequent processing.

[0031] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
