Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to a temperature-controlled organic fertilizer fermentation tank for organic fertilizer production. Background Technology

[0002] Organic fertilizer production is a process that uses organic waste such as livestock and poultry manure and crop straw or natural organic matter as raw materials. Through physical, chemical and biological means, it goes through stages such as raw material collection, pretreatment, fermentation and composting, post-treatment and quality testing to transform organic materials into organic fertilizers that are rich in nutrients needed by plants, can improve soil structure and promote plant growth.

[0003] The core step in the production of fermented organic fertilizer is to use an organic fertilizer fermentation tank to provide a controllable environment for fermentation, meet the growth needs of microorganisms, accelerate the fermentation process, and improve the production efficiency and quality of organic fertilizer. The organic fertilizer fermentation tank consists of a fermentation tank, a stirring device, a heating device, a feeding and discharging device, and a control system. During operation, pre-treated organic materials and microbial inoculants are put in. Aerobic microorganisms, in a suitable temperature, humidity and sufficient oxygen environment, allow the materials to quickly decompose into organic fertilizer and then discharge it from the outlet.

[0004] Existing organic fertilizer fermentation tanks are simple in structure, ingenious in design, and easy to use, meeting the requirements for organic fertilizer fermentation and maturation. However, in terms of mixing methods, they use simple single-shaft stirring. When processing large-scale organic materials, single-shaft stirring is difficult to achieve rapid and thorough mixing of materials, resulting in uneven distribution of materials within the fermentation tank. Some areas are over-fermented, while others are under-fermented, which greatly affects the quality stability and production efficiency of organic fertilizer. At the same time, existing organic fertilizer fermentation tanks usually only set the internal temperature. Microbial fermentation is extremely sensitive to temperature conditions, and different fermentation stages require different suitable temperatures. This method cannot sense and adjust the temperature in real time according to the fermentation process, and can only rely on manual experience for rough adjustments. This is not only labor-intensive, but also prone to poor fermentation results due to temperature deviations. Therefore, a temperature-controlled organic fertilizer fermentation tank for organic fertilizer production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temperature-controlled organic fertilizer fermentation tank for organic fertilizer production, aiming to improve the problems of low stirring efficiency and quality, and inability to intelligently control temperature in the existing technology, which leads to unstable organic fertilizer quality and low production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A temperature-controlled organic fertilizer fermentation tank for organic fertilizer production includes a base, a tank body and a water tank are assembled on the top of the base, a feed inlet and an air inlet pipe are assembled on the top of the tank body, a discharge outlet and a conveying pipe are provided at the bottom of the tank body, a stirring component and a temperature regulating component are provided in the middle of the tank body, a cleaning component is provided inside the tank body, and a conveying component is provided in the middle of the conveying pipe.

[0008] The stirring assembly includes a motor, which is mounted on the top of the tank. The output end of the motor is fixedly connected to a gear and a rotating shaft.

[0015] As a further description of the above technical solution:

[0016] The end of the conveying pipe near the tank is connected to the discharge port, and the first gear and the pair of second gears are meshed together.

[0017] As a further description of the above technical solution:

[0018] The rotating shaft, the stirring block, and the stirring blade are all rotatably connected inside the tank.

[0019] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] The temperature sensor and the heating rod are both electrically connected to the PLC controller.

[0023] This utility model has the following beneficial effects:

[0024] 1.

[0025] 2. In this utility model, the temperature is monitored in real time by a temperature sensor and the data is transmitted to a PLC controller. The PLC controller then automatically controls the working status of the heating rod according to the preset program and the received data, so as to realize intelligent and precise temperature adjustment in the tank, meet the strict temperature requirements of microorganisms at different fermentation stages, reduce the problem of poor fermentation effect caused by temperature deviation, and ensure the smooth progress of fermentation.

[0026] 3. In this utility model, water is pumped to the annular pipe and then sprayed from top to bottom through a dense array of spray nozzles to clean the inside of the tank.

[0027] 4. In this utility model, the auger driven by the second motor rotates inside the conveying pipe, thus constructing an efficient material transfer mechanism. The stable conveying process avoids material blockage and residue, ensures smooth discharge, reduces manual intervention and cleaning costs, and optimizes the production process.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a temperature-controlled organic fertilizer fermentation tank for organic fertilizer production, including a base 1, a tank body 2 and a water tank 3 assembled on the top of the base 1, a feed inlet 4 and an air inlet pipe 6 assembled on the top of the tank body 2, a discharge outlet 5 and a conveying pipe 19 arranged at the bottom of the tank body 2, a stirring assembly 7 and a temperature regulating assembly 22 arranged in the middle of the tank body 2, a cleaning assembly 14 arranged inside the tank body 2, and a conveying assembly 18 arranged in the middle of the conveying pipe 19.

[0035] The stirring assembly 7 includes a motor 8, which is mounted on the top of the tank 2. The output end of the motor 8 is fixedly connected to a gear 9 and a rotating shaft 11. Gears 10 are provided on both sides of the gear 9. A stirring block 12 and a stirring blade 13 are provided on the outer side of the rotating shaft 11. The end of the conveying pipe 19 near the tank 2 is connected to the discharge port 5. The gear 9 and a pair of gears 10 are meshed together. The rotating shaft 11, stirring block 12 and stirring blade 13 are rotatably connected inside the tank 2.

[0036] By starting motor 8, the output of motor 8 generates rotational power, directly driving gear 9 and shaft 11 to rotate synchronously. Based on the gear transmission principle, the meshing gear 9 and the two gears 10 on both sides cause gear 10 to rotate synchronously as well. This causes the stirring block 12 and stirring blade 13 fixed on the outside of shaft 11 to move in a circular motion with shaft 11. The rotating gear 10 drives the connected stirring components to generate additional motion, realizing multi-directional and multi-angle stirring of the material in tank 2. This ensures that the material is fully mixed in different directions and layers, facilitating full contact between microorganisms and nutrients in the material, and helping to improve the fermentation reaction rate.

[0037] Reference Figure 2 The cleaning assembly 14 includes a water pump 15, which is installed in the middle of the cleaning assembly 14. An annular tube 16 is installed inside the tank 2. Spray heads 17 are evenly distributed on the annular tube 16. The annular tube 16 is fixedly connected to the output end of the water pump 15.

[0038] By starting the water pump 15, the water in the water tank 3 is pumped to the annular pipe 16 inside the tank body 2 using the pressure generated by the water pump 15. The water is then sprayed out at a certain pressure and angle through the spray head 17. These sprayed water streams cover the entire interior of the tank body 2, thoroughly flushing the inner wall of the tank body 2, the stirring components, and other internal structures. Due to the all-round flushing of the water stream, residual materials, impurities, and microorganisms attached to the surface of various components inside the tank body 2 can be effectively removed, keeping the inside of the equipment clean and providing good environmental conditions for the next organic fertilizer fermentation.

[0039] Reference Figures 1-3 The temperature regulating component 22 includes a PLC controller 23, which is located on the top of the base 1. A temperature sensor 24 is located in the middle of the tank 2. Heating rods 25 are evenly arranged inside the tank 2. The temperature sensor 24 and the heating rods 25 are electrically connected to the PLC controller 23. The conveying component 18 includes a second motor 20. The output end of the second motor 20 is fixedly connected to an auger 21, which is rotatably connected inside the conveying pipe 19.

[0040] Temperature sensor 24 collects temperature data of tank 2 in real time and transmits it to PLC controller 23. PLC controller 23 analyzes and judges the working status of automatic heating rod 25 to avoid fermentation abnormalities caused by temperature fluctuations and ensure efficient and stable fermentation of organic fertilizer. By starting motor 20, motor 20 drives auger 21 to rotate in conveying pipe 19. One end of conveying pipe 19 is tightly connected to the discharge port 5 at the bottom of tank 2. When auger 21 rotates, it pushes the fermented organic fertilizer to form a stable material flow in conveying pipe 19 and continuously discharges it from discharge port 5, making the discharge process smooth and continuous, which is conducive to improving discharge efficiency.

[0041] Working principle: First, organic raw materials such as livestock and poultry manure and crop straw are put into tank 2 through inlet 4, and fermentation bacteria are introduced at the same time. At this time, motor 8 is started, so that the output end of motor 8 drives gear 9 and shaft 11 to rotate. Gear 9 drives gear 10 to rotate synchronously. Through gear 9 driving gear 10, the stirring blade 13 and stirring block 12 are stirred in all directions and at multiple angles to stir the material in tank 2.

[0042] During the fermentation process, the temperature is monitored in real time by the temperature sensor 24 and the data is transmitted to the PLC controller 23 set on the top of the base 1. The PLC controller 23 automatically controls the working state of the heating rods 25 evenly arranged inside the tank 2 according to the preset program and the received temperature data, and intelligently adjusts the temperature inside the tank. At the same time, fresh air from outside continuously enters the tank 2 through the air inlet pipe 6 to provide sufficient oxygen for aerobic microorganisms.

[0043] After the organic fertilizer fermentation is completed, start motor 20 to drive auger 21 to rotate in conveying pipe 19, and discharge the decomposed organic fertilizer from outlet 5. After the discharge is completed, water pump 15 can be turned on to transport water from water tank 3 to annular pipe 16 inside tank 2, and then sprayed out by spray nozzles 17 evenly distributed on annular pipe 16 to clean the inside of tank 2 for the next use.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
