Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a fermentation device for urban waste treatment. Background Technology
[0002] Fermentation in urban waste management is a process that uses microorganisms to decompose and transform organic matter in waste. It is mainly used to process organic waste, such as kitchen waste and garden waste. Because waste produces a lot of odor and moisture during fermentation, waste fermentation usually needs to be carried out in an open space away from residential areas.
[0003] Currently, the fermentation treatment of municipal solid waste generally involves large-scale dumping and composting. However, due to the large dumping area, the waste inside is not easily exposed to air, and the temperature difference between the internal and external fermentation is too large, which can easily lead to incomplete fermentation. Furthermore, the waste liquid produced during fermentation is not easy to discharge, which can affect the fermentation effect. Utility Model Content
[0004] The purpose of this invention is to provide a fermentation device for urban waste treatment, which can adopt modular fermentation boxes, allowing multiple fermentation boxes to be spliced together and the waste to be turned over and mixed in a coordinated manner to promote fermentation efficiency.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A fermentation device for municipal waste treatment includes a fermentation tank and a cover plate. The cover plate is disposed on the top of the fermentation tank. A fermentation cylinder is disposed inside the fermentation tank. The fermentation cylinder has a hollow structure. A rotating shaft is fixedly connected to both ends of the fermentation cylinder. Two grooves are formed on the top end face of the fermentation tank. The rotating shaft is rotatably connected to the grooves. A sealing plate is installed on the side wall of the fermentation cylinder. A docking assembly is disposed on the side wall of the rotating shaft. A pipeline connection assembly is also disposed on the side wall of the fermentation tank.
[0007] The docking assembly includes two locking blocks fixedly connected to the left side wall of the rotating shaft, and a cylinder fixedly connected to the right end face of the rotating shaft. The end face of the cylinder has several locking slots, and the locking blocks are adapted to the locking slots.
[0008] The pipeline connection assembly includes a first pair of connecting pipes fixedly connected to the right side wall of the fermentation tank, and a second pair of connecting pipes fixedly connected to the left side wall of the fermentation tank near the bottom. The diameter of the first pair of connecting pipes is smaller than the inner diameter of the second pair of connecting pipes. Both the first pair of connecting pipes and the second pair of connecting pipes have external threads on their side walls. The first pair of connecting pipes has a threaded sleeve connected to its side wall, and the second pair of connecting pipes has a valve installed on its side wall.
[0009] Positioning rods are fixedly connected to the bottom surface of the fermentation tank near the four corners, and positioning cylinders are fixedly connected to the top surface of the cover plate near the four corners. The diameter of the positioning rods is smaller than the inner diameter of the positioning cylinders.
[0010] Limiting plates are fixedly connected to the side walls of the rotating shaft within the fermentation chamber.
[0011] The side wall of the limiting plate is fixedly connected with several hooks.
[0012] The technical effects achieved by this utility model are as follows:
[0013] This utility model discloses a fermentation device for urban waste treatment. Through the cooperation of fermentation boxes, cover plates, fermentation cylinders and docking components, a modular fermentation box is adopted, which can splice multiple fermentation boxes together and turn and mix the waste in a linkage manner.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] like Figures 1-6 As shown, a fermentation device for urban waste treatment includes a fermentation box 1 and a cover plate 2. The cover plate 2 is set on the top of the fermentation box 1. A fermentation cylinder 3 is set in the inner cavity of the fermentation box 1. The fermentation cylinder 3 has a hollow structure. Rotating shafts 4 are fixedly connected to both ends of the fermentation cylinder 3. Two grooves 5 are opened on the top end face of the fermentation box 1. The rotating shafts 4 are rotatably connected to the grooves 5. A sealing plate 9 is installed on the side wall of the fermentation cylinder 3. A docking component is set on the side wall of the rotating shaft 4. A pipeline connection component is also set on the side wall of the fermentation box 1.
[0024] like Figure 3 and Figure 4 As shown, the docking assembly includes two locking blocks 6 fixedly connected to the side wall of the left rotating shaft 4, and a cylinder 7 fixedly connected to the end face of the right rotating shaft 4. The end face of the cylinder 7 is provided with several locking slots 8, and the locking blocks 6 are adapted to the locking slots 8.
[0025] When multiple fermentation boxes 1 are used in combination, they can be stacked horizontally, and multiple layers can be stacked. The fermentation boxes 1 are connected by the locking block 6 and the locking slot 8 to realize the linkage between multiple fermentation cylinders 3. When the outermost rotating shaft 4 is driven by an external motor, the fermentation cylinders 3 located on the same axis rotate synchronously, which facilitates the turning of garbage and effectively promotes fermentation efficiency.
[0026] like Figure 5 and Figure 6 As shown, the pipeline connection assembly includes a first pair of connecting pipes 11 fixedly connected to the right side wall of the fermentation tank 1, and a second pair of connecting pipes 10 fixedly connected to the left side wall of the fermentation tank 1 near the bottom. The diameter of the first pair of connecting pipes 11 is smaller than the inner diameter of the second pair of connecting pipes 10. Both the first pair of connecting pipes 11 and the second pair of connecting pipes 10 have external threads on their side walls. The side wall of the first pair of connecting pipes 11 is threaded with a threaded sleeve 12, and the side wall of the second pair of connecting pipes 10 is equipped with a valve 13.
[0027] Specifically, when the card block 6 is connected to the card slot 8, the first pair of connecting pipes 11 is inserted into the second pair of connecting pipes 10, and then the screw sleeve 12 is rotated so that the screw sleeve 12 is located between the first pair of connecting pipes 11 and the second pair of connecting pipes 10, which plays a role in sealing and fixing, facilitating the flow of waste liquid inside multiple fermentation tanks 1. By extracting the waste liquid in one fermentation tank 1, the waste liquid in other fermentation tanks 1 can be discharged simultaneously.
[0028] like Figure 2As shown, positioning rods 14 are fixedly connected to the bottom surface of fermentation tank 1 near the four corners, and positioning cylinders 15 are fixedly connected to the top surface of cover plate 2 near the four corners. The diameter of the positioning rods 14 is smaller than the inner diameter of the positioning cylinders 15. In order to further save the space occupied by fermentation tank 1, multiple fermentation tanks 1 can be stacked and positioned using positioning rods 14 and positioning cylinders 15, thereby increasing the fermentation capacity of waste.
[0029] like Figure 3 As shown, limiting plates 16 are fixedly connected to the side walls of the rotating shaft 4 within the inner cavity of the fermentation tank 1. The limiting plates 16 are used to limit the rotation of the two rotating shafts 4 on both sides to prevent displacement during fermentation or transmission, which would affect the transmission efficiency between multiple fermentation tanks 3.
[0030] like Figure 3 As shown, several hooks 17 are fixedly connected to the side wall of the limiting plate 16. In order to facilitate the removal and placement of the fermentation cylinder 3 from the fermentation box 1, the hooks 17 can be hoisted by external lifting equipment to realize the transportation of the fermentation cylinder 3.
[0031] The working principle of this utility model is as follows: First, the garbage is placed inside the fermentation cylinder 3 and covered with the sealing plate 9. Then, the fermentation cylinder 3 is hoisted and placed in the fermentation box 1 through the hook 17, so that the rotating shaft 4 is located in the groove 5, and the cover plate 2 is covered for fermentation. When multiple fermentation boxes 1 need to be stacked together, the multiple fermentation boxes 1 are first stacked horizontally, so that the left rotating shaft 4 is inserted into the cylinder 7, and the locking block 6 is locked into the slot 8. The outermost fermentation box 1 is connected to the external motor for transmission. When it is necessary to turn the garbage in the fermentation cylinder 3, the external motor is started to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the fermentation cylinder 3 to rotate, and the fermentation cylinder 3 drives the other cylinder 7 to rotate. By using the cooperation of the slot 8 and the locking block 6, the other fermentation cylinders 3 are driven in sequence, so that the inner layer of garbage can be fully mixed with the outer layer of garbage, avoiding uneven fermentation, thereby promoting fermentation efficiency.
[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
