[0001] The utility model relates to the technical field of fertilizer production, specifically a microbial fertilizer fermentation tank. Background Art

[0002] Microbial fertilizer is a kind of fertilizer that improves soil by adding beneficial microorganisms. These microorganisms can help improve soil fertility and structure, and promote plant growth and health. Common microbial fertilizers include compound microbial fertilizers and bio-organic fertilizers containing beneficial strains, which can promote plant nutrient absorption, enhance plant resistance to adversity, and reduce the use of chemical fertilizers at the same time.

[0003] During the production and processing of microbial fertilizers, raw materials and an appropriate amount of microbial bacterial liquid need to be added to the fermentation tank for fermentation treatment. In order to control the fermentation process and improve fermentation efficiency, some enterprises add the bacterial liquid in batches. In this way, new bacterial liquid needs to be added to the fermentation tank at different stages of fermentation to maintain the activity and quantity of microorganisms. The existing method of adding bacterial liquid mainly involves manually measuring the bacterial liquid, opening the cover plate of the tank body feed pipe to add the bacterial liquid into the tank body, and then closing the cover plate. The steps are cumbersome and inconvenient. Content of the Utility Model

[0019] As Figure 1 and Figure 2 shown, the microbial fertilizer fermentation tank includes a tank body 1. The top of the tank body 1 is provided with a feed pipe 2 and an exhaust pipe 3, and the bottom is provided with a discharge pipe 4. A protective shell 12 is arranged outside the tank body 1. A heating chamber is formed between the protective shell 12 and the outer wall of the tank body 1. Steam input pipes 13 and steam output pipes 14 are respectively arranged on the upper parts of both sides of the heating chamber, and a condensate discharge pipe 15 is arranged at the bottom of the heating chamber. A valve is installed on the condensate discharge pipe 15. The middle part of the side of the discharge pipe 4 is connected with an air inlet pipe 16. An air filter 17 is installed in the middle of the air inlet pipe 16. A discharge valve is installed at the bottom of the discharge pipe 4. A one-way valve is installed at one end of the air inlet pipe 16 close to the discharge pipe 4.

[0020] Connecting the steam input pipe 13 and the steam output pipe 14 to the steam heating system can realize the heating of the tank body 1. Connecting the air inlet pipe 16 to an external fan, when the fan works, air is conveyed into the tank body 1, which can increase the oxygen content inside the tank body 1 and promote aerobic fermentation. The air filter 17 can filter the air entering the tank body 1 to prevent external dust, bacteria, etc. from entering the tank body 1.

[0021] As Figure 1 and Figure 3 shown, a stirring assembly is installed through the top of the tank body 1. The stirring assembly includes a motor 18 installed on the top of the tank body 1. The output end of the motor 18 is installed with a speed reducer 19. The output end of the speed reducer 19 is installed with a stirring shaft 20 passing through the top surface of the tank body 1. A first stirring blade 21 is installed in the middle of the stirring shaft 20, and a second stirring blade 22 is installed at the bottom. The first stirring blade 21 is a spiral ribbon paddle and there are two of them. The second stirring blade 22 is a blade with a U-shaped structure.

[0022] The motor 18 drives the stirring shaft 20 to rotate through the speed reducer 19. The stirring shaft 20 drives the first stirring blade 21 and the second stirring blade 22 to rotate, which can mix the bacterial liquid and raw materials evenly, and at the same time ensure the uniform distribution of oxygen and nutrients, which is beneficial to the growth and metabolism of microorganisms and improves the fermentation efficiency.

[0023] As Figure 1 and Figure 4As shown in the figure, a microbial automatic feeding assembly is installed on the top of the tank body 1 on one side of the stirring assembly. The automatic feeding assembly includes a bacterial agent box 5 installed on the top of the tank body 1. The bottom of the bacterial agent box 5 is connected to a buffer cylinder 7 through a connecting pipe 6. The upper part of the side of the buffer cylinder 7 is connected to a conduit 8 passing through the top surface of the tank body 1.

A positioning block is fixedly connected between the buffer cylinder 7 and the support rods 23. Solenoid valves are installed on both the connecting pipe 6 and the conduit 8.

[0024] Add microbial bacterial liquid into the bacterial agent box 5. By the telescopic movement of the electric push rod 10 to drive the piston 11 to move up and down, the distance between the piston 11 and the inner top surface of the buffer cylinder 7 can be adjusted. Since the size of the buffer cylinder 7 is fixed, the volume for holding the bacterial liquid above the piston 11 can be obtained according to the telescopic length of the electric push rod 10. Furthermore, the telescopic length of the electric push rod 10 can be adjusted according to the volume of the bacterial liquid to be added as needed.

[0025] Open the solenoid valve on the connecting pipe 6. The electric push rod 10 contracts to a set value, so that the bacterial liquid enters the inside of the buffer cylinder 7 through the connecting pipe 6. Close the solenoid valve on the connecting pipe 6 and open the solenoid valve on the conduit 8. The electric push rod 10 extends, and the bacterial liquid inside the buffer cylinder 7 can be added into the tank body 1 through the conduit 8 by the piston 11, realizing the automatic addition of the bacterial liquid.

[0026] In specific use, connect the electric push rod 10, the motor 18 and the solenoid valve of the device to the control system. Add the raw materials into the tank body 1 through the feed pipe 2 and cover the cover plate on the feed pipe 2. Add microbial bacterial liquid into the bacterial agent box 5. Open the solenoid valve on the connecting pipe 6 and at the same time the electric push rod 10 contracts, so that the bacterial liquid enters the inside of the buffer cylinder 7. Close the solenoid valve on the connecting pipe 6 and open the solenoid valve on the conduit 8, and the electric push rod 10 extends, and the bacterial liquid can be added into the tank body 1. The motor 18 drives the stirring blade one 21 and the stirring blade two 22 to rotate to mix the bacterial liquid and the raw materials evenly, which is beneficial to the reaction between the bacterial liquid and the raw materials.
