[0002] In corporate farms, large-scale fermentation equipment is usually used, such as open-air fermentation fields and large fermentation tanks, but large fermentation tanks are large in size and costly, and are not suitable for small-scale farms. In small-scale farms such as rural areas, there is a greater demand for small-scale, low-cost fermentation tanks. Herders place livestock and poultry waste in fermentation tanks in livestock farms, which eventually form organic fertilizers suitable for crop growth and are transported to the planting area.

[0003] In the fermentation process of aquaculture waste, the factors that affect the fermentation effect are mainly the following: temperature, humidity, aeration (aerobic fermentation), fermentation time, raw material types and ratios, microbial types and quantities, etc. Among them, since the fermentation tank is in the early and middle stages of fermentation, especially when microorganisms are vigorously decomposing organic matter and generating a lot of heat, opening the tank body may cause drastic changes in temperature, humidity and aeration, which may affect the activity of microorganisms and may even cause the fermentation process to be interrupted or the fermentation effect to be reduced. The existing fermentation tank has a relatively simple structure and only uses a thermometer for simple temperature monitoring. It is impossible to control the temperature in the fermentation tank, resulting in fermentation failure or reduced fermentation effect.

[0051] See attached Fig.11 and Fig.12 As shown, in the utility model, the heat dissipation assembly 5 includes a heat dissipation hole 51 arranged on the top of the tank body 1, a square heat dissipation tube 52 installed on the top of the tank body 1 and located at the opening of the heat dissipation hole 51, a heat dissipation fan 53 installed in the square heat dissipation tube 52, a placement frame 54 installed in the square heat dissipation tube 52, a handle 55 installed on the placement frame 54, a heat dissipation electric cylinder 56 installed on the outer wall of the square heat dissipation tube 52, a cover 57 installed on the heat dissipation electric cylinder 56 and corresponding to the square heat dissipation tube 52, and the heat dissipation fan 53 is located between the heat dissipation hole 51 and the placement frame 54.

[0052] The utility model cools down the fermentation environment inside the tank body 1 through the provision of heat dissipation holes 51, thereby reducing the ambient temperature of the fermentation of aquaculture waste and preventing the ambient temperature from being too high and affecting the fermentation; through the provision of square heat dissipation tubes 52, installation positions are provided for the heat dissipation fan 53, the heat dissipation electric cylinder 56 and the placement frame 54; through the provision of the placement frame 54, activated carbon or carbon-based materials can be placed in the placement frame 54 to purify the gas produced by the fermentation before discharging it, and to adsorb gases such as methane in the fermentation gas, thereby protecting the environment; through the provision of the handle 55, it is convenient for the staff to take out the placement frame 54 and replace the activated carbon or carbon-based materials; through the provision of the heat dissipation fan 53, the gas in the tank body 1 can be discharged; it should be particularly noted that the ventilation fan 16 in the present application works by blowing external air into the tank body 1, and the heat dissipation fan 53 drives the gas in the tank body 1 to move to the outside.

[0053] See attached Figure 1 — Fig.12As shown, the use process of the utility model is as follows:

[0054] In the first step, the staff controls the electromagnetic valve 62 on the feed pipe 6 to open through the PLC controller 8, and then puts the aquaculture waste into the tank body 1 through the feed funnel 61, until the photoelectric liquid level sensor 14 senses that the aquaculture waste has reached the specified position, and sends a signal to the PLC controller 8. The PLC controller 8 can control the buzzer connected to it to remind the staff, and control the electromagnetic valve 62 on the feed pipe 6 to close after the specified time;

[0055] In the second step, the staff controls the motor 22 through the PLC controller 8 to start working, and the motor 22 drives the stirring blade 24 to stir the breeding waste through the stirring shaft 23;

[0056] The third step is carried out simultaneously with the second step. The temperature sensor 9 senses the temperature in the tank body 1 and transmits the signal to the PLC controller 8. The PLC controller 8 compares the obtained signal with the specified temperature. When the temperature is lower than the specified temperature, the PLC controller 8 controls the electric cylinder 41, the booster air pump 43 and the heating coil 47 in the circulation heating structure 4 to start working. The electric cylinder 41 drives the booster air pump 43 to move downward through the mounting plate 42, so that the joint 46 at the end of the hot air outlet pipe 45 is connected to the top of the stirring shaft 23, and the stirring assembly 2 starts to be heated.

[0057] Specifically, the booster air pump 43 starts working, and the gas in the tank body 1 is sucked through the air inlet pipe 44, and then pressurized by the booster air pump 43, and then heated by the heating coil 47 in the hot air outlet pipe 45, and then enters the stirring shaft 23 through the heat exchange hole 231, exchanges heat along the heat exchange hole 231, and finally is discharged from the air outlet 233 and enters the tank body 1. During the movement of the hot air, the heated gas contacts the semi-conical air guide block 261, and part of the gas enters the heat exchange groove 241 to exchange heat with the stirring blade 24.

[0058] Step 4: When the temperature detected by the temperature sensor 9 is higher than the specified temperature range, the PLC controller 8 controls the circulation heating structure 4 to reset, that is, the electric cylinder 41 is reset, and the booster air pump 43 and the heating coil 47 stop working. At the same time, the PLC controller 8 controls the cooling fan 53 and the ventilation fan 16 to start working, and the cooling electric cylinder 56 drives the cover 57 to move upward. After the circulation heating structure 4 is reset, the heat exchange hole 231 is connected to the internal environment of the tank body 1, and the cooling fan 53 starts working, the temperature in the tank body 1 is reduced, and the temperature of the stirring shaft 23 can also be effectively reduced, and the cooling speed can be accelerated, so that the temperature can be efficiently adjusted;

[0059] In the fifth step, when the oxygen concentration in the tank body 1 monitored by the oxygen battery 17 is compared with the oxygen concentration set in the PLC controller 8, when it is lower than the specified oxygen concentration, the PLC controller 8 controls the ventilation fan 16 to start working and blow air into the tank body.

[0060] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
