Description

Technical Field

[0001] This utility model relates to the field of fermentation composting tank technology, and in particular to a discharge anti-blocking device for fermentation composting tanks. Background Technology

[0002] Fermentation composting pits are facilities used to convert organic waste into humus (compost) through microbial fermentation. They are widely used in agriculture, horticulture, and organic waste treatment. By controlling temperature, humidity, oxygen, and microbial activity, fermentation composting pits accelerate the decomposition of organic matter and ultimately produce stable organic fertilizer. Compared with traditional composting, fermentation pits can control environmental conditions more efficiently and shorten the composting cycle.

[0003] Material blockage is a frequent problem encountered during the discharge operation of fermentation composting pits. When blockage occurs, the machine must be stopped for unblocking, which undoubtedly prolongs the entire operation time and affects the efficiency of the entire composting cycle. Furthermore, blockage can prevent the timely discharge of some material, causing it to remain in the composting pit. This retained material may produce harmful gases such as methane and hydrogen sulfide in an anaerobic environment, posing a threat not only to the environment but also to the health of operators. Utility Model Content

[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. 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.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a discharge anti-blocking device for a fermentation composting tank, comprising a connecting pipe 1, an equipment box 4 fixedly connected to one side of the outer wall of the connecting pipe 1, a crushing pipe 2 fixedly connected to the bottom of the connecting pipe 1, a rotating shaft 7 rotatably connected inside the connecting pipe 1, a auger blade 6 fixedly connected to the outer wall of the rotating shaft 7, a fixing block 11 fixedly connected inside the crushing pipe 2, a rotating shaft 10 rotatably connected inside the fixing block 11, pulleys 13 fixedly connected to one side of the outer wall of both the rotating shaft 10 and the rotating shaft 7, and a belt 14 disposed between the two pulleys 13. The equipment box 4 contains a... A motor 9 is fixedly connected to the side, and the output end of the motor 9 is fixedly connected to one end of the rotating shaft 10. A rotating column 15 is rotatably connected inside the fixed block 11. A helical gear 18 is fixedly connected to one side of the outer wall of the rotating shaft 10. A helical gear 17 is fixedly connected to the outer wall of the rotating column 15. The outer wall of the helical gear 17 meshes with the outer wall of the helical gear 18. An eccentric shaft 16 is fixedly connected inside the rotating column 15. A crushing wheel 12 is fixedly connected to the outer wall of the eccentric shaft 16. A discharge assembly is provided at the bottom of the crushing pipe 2. The discharge assembly includes a discharge pipe 3. The top of the discharge pipe 3 is fixedly connected to the bottom of the crushing pipe 2.

[0024] Specifically, when starting the discharge process of the fermentation composting tank, the motor 9 is turned on. The output shaft of the motor 9 is connected to the rotating shaft 10. As the motor 9 starts, the rotating shaft 10 begins to rotate at a constant speed under its drive. On one side of the rotating shaft 10, a pulley 13 is installed. The surface of the pulley 13 is designed with grooves that match the belt 14 to increase friction and prevent belt slippage. At the same time, a matching pulley 13 is also installed on the rotating shaft 7. The two pulleys 13 form a belt group through the belt 14, forming a belt drive mechanism. When the rotating shaft 10 rotates, it drives the pulleys 13 to rotate synchronously. Power is transmitted to the pulley 13 on the rotating shaft 7 through the tension of the belt 14, thereby driving the rotating shaft 7 to rotate. The outer wall of the rotating shaft 7 is spirally wound with auger blades 6, which are made of high-strength stainless steel and have good wear resistance and corrosion resistance. As the rotating shaft 7 rotates, the auger blades 6 begin to perform their unique conveying function. Through their spiraling curved structure, they continuously move the material in the composting pit along the pit wall and gradually push it into the interior of the connecting pipe 1, and then it falls into the crushing pipe 2. Simultaneously with the rotation of the rotating shaft 10, a helical gear fixedly installed at one end... The second helical gear 18 also rotates. The tooth surface of the second helical gear 18 has a special inclined angle design and meshes with the first helical gear 17. When the second helical gear 18 rotates, it drives the first helical gear 17 to rotate through the meshing and thrust transmission between the teeth. The first helical gear 17 is installed at one end of the rotating column 15. As the first helical gear 17 rotates, the rotating column 15 also begins to rotate synchronously. The rotation of the rotating column 15 provides the power basis for the movement of the crushing wheel 12. An eccentric shaft 16 is installed on the rotating column 15. The axis of the eccentric shaft 16 has a certain eccentricity with the axis of the rotating column 15. The crushing wheel 12 is fixed. On the eccentric shaft 16, when the rotating column 15 rotates, the eccentric shaft 16 will drive the crushing wheel 12 to perform eccentric circular motion. The outer surface of the crushing wheel 12 is distributed with staggered crushing teeth, while the inner wall of the crushing tube 2 is provided with corresponding tooth grooves and protrusions. During the eccentric circular motion of the crushing wheel 12, its crushing teeth will continuously cooperate with the structure of the inner wall of the crushing tube 2 to squeeze, shear and impact the material falling into the crushing tube 2. In this way, large pieces of material are gradually crushed into fine particles, effectively preventing the material from being blocked in the discharge pipe due to its large volume, and ensuring the smooth operation of the entire discharge system.

[0025] Reference Figure 1 and Figure 2 A sealing ring 8 is fixedly connected inside the connecting pipe 1;

[0026] Specifically, a sealing ring 8 is provided inside the connecting pipe 1. When the discharge pipe is fixed inside the connecting pipe 1, its front end will fit against the sealing ring 8, thereby keeping the connecting pipe 1 and the discharge pipe sealed.

[0027] Reference Figure 2 and Figure 4 A drive ring 5 is threadedly connected to the outer wall of the connecting pipe 1. A wedge block 19 is slidably connected inside the connecting pipe 1. The outer wall of the wedge block 19 fits against the inner wall of the drive ring 5. A clamping plate 20 is fixedly connected to the bottom of the wedge block 19. The outer wall of the clamping plate 20 is slidably connected inside the connecting pipe 1. Pressure plates 23 are fixedly connected to both sides of the outer wall of the clamping plate 20. A limit post 21 is fixedly connected to the inner wall of the connecting pipe 1. A spring 22 is sleeved on the outer wall of the limit post 21. One end of the spring 22 is fixedly connected to the outer wall of the pressure plate 23, and the other end of the spring 22 is fixedly connected to the inner wall of the connecting pipe 1.

[0028] Specifically, during the discharge operation of the fermentation composting tank, the operator must first align the discharge pipe with the port of the connecting pipe 1 and insert it into the connecting pipe 1. After the discharge pipe is inserted into place, the operator must hold the drive ring 5, which is fitted onto the outside of the connecting pipe 1. As the operator rotates the drive ring 5, the drive ring 5 begins to move along its circumferential trajectory. The inner wall of the drive ring 5 is specially designed with an inclined slope structure that matches the wedge block 19. When the drive ring 5 rotates, its inner wall... The inclined slope will gradually come into contact with the wedge block 19 and apply a pushing force towards the center of the connecting pipe 1. As the wedge block 19 slides, it will drive the clamping plate 20 to move synchronously towards the center of the connecting pipe 1. The inner surface of the clamping plate 20 is specially treated and covered with anti-slip rubber material. When the clamping plate 20 gradually approaches and adheres to the outer wall of the discharge pipe, it can generate a sufficiently large friction force, thereby firmly pressing the discharge pipe inside the connecting pipe 1 to ensure that there is no loosening during the discharge process. In case of leakage or other issues, to ensure the smooth progress of the discharge operation, when the discharge operation is completed and the discharge pipe needs to be removed, the operator needs to rotate the drive ring 5 in the opposite direction. At this time, the pressure between the inner wall of the drive ring 5 and the wedge block 19 is gradually released, and the wedge block 19 loses the restraining force from the drive ring 5. A reset device is installed on the outside of the connecting pipe 1. This device mainly consists of a spring 22 and a pressure plate 23. One end of the spring 22 is fixed on the outer wall of the connecting pipe 1, and the other end is connected to the pressure plate 23. When the discharge pipe is fixed, the spring 22 is in a compressed state and stores elastic potential energy. When the wedge block 19 loses its restraint, the spring 22 begins to release elastic potential energy, pushing the pressure plate 23 to move away from the center of the connecting pipe 1. The pressure plate 23 is connected to the clamping plate 20. As the pressure plate 23 moves, the clamping plate 20 is also driven to slide to the outside of the connecting pipe 1. When the clamping plate 20 completely releases its grip on the discharge pipe, the operator can remove the discharge pipe from the connecting pipe 1, completing the entire discharge and pipe disassembly operation process.

[0029] Working principle: When discharging material from the fermentation composting tank, the discharge pipe can be inserted into the connecting pipe 1. Rotating the drive ring 5 causes the inner wall of the drive ring 5 to push the wedge block 19, which in turn pushes the clamping plate 20 towards the center of the connecting pipe 1, thus pressing the inner wall of the discharge pipe. When removing the discharge pipe, the drive ring 5 can be rotated in the opposite direction. The wedge block 19 will then lose the restraint of the drive ring 5, and the force of the spring 22 will push the pressure plate 23, causing the pressure plate 23 to slide the clamping plate 20 towards the outside of the connecting pipe 1, allowing the discharge pipe to be removed. During discharge, the motor 9 can drive the rotating shaft 2. When shaft 10 rotates, shaft 10 can drive shaft 7 to rotate via belt assembly consisting of pulley 13 and belt 14. The auger blades 6 on the outer wall of shaft 7 will carry material into the connecting pipe 1 and into the crushing pipe 2. As shaft 10 rotates, the helical gear 18 at one end of shaft 10 will rotate accordingly, driving helical gear 17 to rotate, thereby causing the rotating column 15 to rotate. The rotating column 15 then drives the crushing wheel 12 to perform eccentric circular motion via eccentric shaft 16, which can work with the inner wall of the crushing pipe 2 to crush the material, thus preventing material blockage.

[0030] 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.
