Description

Technical Field

[0001] This utility model relates to the field of fertilizer production, specifically a liquid fermentation tank for livestock and poultry manure. Background Technology

[0002] The harmless treatment and resource utilization technology of the liquid portion of livestock and poultry manure is a global challenge for achieving a circular economy in modern agriculture. For many years, it has been a key focus of research by numerous professional institutions. Its main technologies include:

[0003] 1. Anaerobic fermentation in a closed container: This means that the biogas slurry is fermented in a state of isolation from oxygen. It is divided into two types: 1. Microbial addition method, which takes about 30 days; 2. Natural fermentation method, which takes more than 90 days.

[0004] Second, non-sealed container "aerobic fermentation": mostly made of cement concrete to form ponds or large steel containers, etc., and there are two types: 1. Adding microorganisms, aeration, stirring, the fermentation cycle is about 20 days in summer when the temperature is high, and about 60 days or more in winter when the temperature is below 15 degrees Celsius; 2. Without adding microorganisms, the fermentation cycle is more than 90 days.

[0005] The above processing methods are the current common practices. Their main drawbacks are: the cycle is too long, the cost is increased, and the efficiency is too low; secondly, the processed indicators are unstable and cannot be used directly as commodities, resulting in low returns.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, a liquid fermentation tank for livestock and poultry manure includes a tank body 1. The top of the tank body 1 is provided with a manhole 2, the upper side is provided with a feed pipe 3 and an overflow pipe 4, and the lower part is provided with a discharge pipe 5. A cover plate is installed at the manhole 2, and a valve is installed on the discharge pipe 5.

[0024] The feed pipe 3 can be used to transport sewage liquid into the tank 1. The overflow pipe 4 can be used to prevent the liquid level inside the tank 1 from being too high. The height of the overflow pipe 4 is equal to or slightly lower than the height of the feed pipe 3.

[0025] A drive shaft 6 is rotatably mounted through the top of the tank body 1, and a rotating shaft 7 is rotatably mounted on the inner bottom. A power source for driving the drive shaft 6 is mounted on the top of the tank body 1 via a bracket 8. The power source includes a servo motor 19, the output end of which is connected to a reducer 20. The output end of the reducer 20 is connected to the drive shaft 6 via a coupling. Positioning seats 21 are mounted on both the top surface and the inner bottom surface of the tank body 1. The drive shaft 6 and the rotating shaft 7 are rotatably connected to the two positioning seats 21 via bearings. The diameters of the drive shaft 6 and the rotating shaft 7 are the same.

[0026] When the servo motor 19 is working, it drives the reducer 20 to rotate, and the reducer 20 can drive the transmission shaft 6 to rotate through the coupling.

[0027] An electric actuator 9 is installed on the top of the tank body 1. A horizontal plate 10 is installed inside the tank body 1 at the output end of the electric actuator 9. A central shaft 11 is rotatably installed through the middle of the horizontal plate 10. The two ends of the central shaft 11 are movably connected to the transmission shaft 6 and the rotating shaft 7, respectively. A U-shaped stirring blade 12 is installed at the bottom of the central shaft 11, and two inclined blades 13 are installed in the middle. A positioning seat 21 is installed on the bottom surface of the horizontal plate 10. The central shaft 11 is rotatably connected to the positioning seat 21 through a bearing. Positioning holes are opened at both ends of the central shaft 11, and the two ends of the central shaft 11 are respectively sleeved on the outside of the transmission shaft 6 and the rotating shaft 7 through the positioning holes. Two limiting strips 22 are symmetrically fixed to the inner side wall of the positioning holes. Limiting grooves that are adapted to the limiting strips 22 are opened on the sides of the transmission shaft 6 and the rotating shaft 7.

[0028] The limiting strip 22 and the limiting groove enable the drive shaft 6 to rotate, which in turn drives the central shaft 11 to rotate. The central shaft 11 then drives the rotating shaft 7 to rotate, which in turn drives the stirring blade 12 and the paddle blade 13 to rotate, thus achieving the stirring of the sewage liquid. The extension and retraction of the electric push rod 9 causes the horizontal plate 10 to move the central shaft 11 up and down, which enables the stirring of liquids at different heights. When the paddle blade 13 rotates, it pushes the liquid downward, which can improve the stirring efficiency.

[0029] An annular aeration pipe 14 is installed at the bottom of the tank 1. Multiple aeration discs 15 are provided at the top of the aeration pipe 14. A conveying pipe 16 extending to the top of the tank 1 is connected to the top of the aeration pipe 14.

[0030] The conveying pipe 16 is connected to the blower. When the blower is working, it conveys airflow into the aeration pipe 14 through the conveying pipe 16. The airflow is then conveyed into the tank 1 through the aeration disc 15 to achieve aeration treatment of the sewage liquid, enhance the aerobic reaction of the sewage liquid, meet the needs of rapid reproduction of aerobic microorganisms, and achieve the purpose of rapid fermentation.

[0031] Multiple mounting bases 23 are installed on the inner side wall of the tank 1 from top to bottom. Various sensors for measuring pH value, conductivity, ECE value, dissolved oxygen and temperature are installed on the mounting bases 23. A level gauge 17 and a camera 18 are also installed on the top inside the tank 1. The level gauge 17 is an ultrasonic level gauge. A supplementary light 24 is installed on the top inside the tank 1 on one side of the camera 18.

[0032] A PLC controller is installed on the top of the tank 1. The servo motor 16, electric actuator 9, sensor, level gauge 17, camera 18, and supplementary light 24 are all connected to the PLC controller via bus communication.

[0033] Both the PLC controller and camera 18 are connected to the monitoring terminal in the control room, such as a computer. Through the monitoring terminal, staff can understand the changes in various parameters during the fermentation process in real time, and at the same time control the liquid level, aeration volume and changes in the fermentation process, so as to realize the scientific, efficient and environmentally friendly modern production of livestock and poultry manure liquid organic liquid fertilizer.

[0034] In practical use, manure liquid can be conveyed into the tank 1 through the feed pipe 3. The servo motor 19 drives the stirring blade 12 and the paddle blade 13 to rotate. The extension and retraction of the electric push rod 9 causes the horizontal plate 10 to drive the central shaft 11 to move up and down, thereby realizing the stirring of manure liquid and improving the speed of uniform stirring of manure liquid. Through the monitoring terminal, the changes of various parameters in the fermentation process can be understood in real time, and the liquid level, aeration volume and changes in the fermentation process can be controlled at the same time, so as to realize the scientific, efficient and environmentally friendly modern production of livestock and poultry manure liquid organic liquid fertilizer.

[0035] This fermenter treats livestock and poultry manure liquid by reducing the fermentation time to about 3 days, thus improving fermentation efficiency. It also facilitates monitoring of the fermentation process. The treated livestock and poultry manure liquid (biogas slurry) is transformed into a nutrient-rich organic liquid fertilizer that plants need. It can be used directly and can generate considerable economic, social, and ecological benefits.
