Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, and in particular to a solid waste treatment device. Background Technology

[0002] Solid waste treatment refers to a series of processes involving waste generated by human activities, aiming to reduce its impact on the environment and human health, and to achieve the effective utilization of resources. The three main methods of solid waste treatment are incineration, pyrolysis, and composting. Incineration involves burning combustible solids in a high-temperature furnace, which can eliminate various pathogens and recover heat energy; this method is commonly used to treat municipal solid waste. Pyrolysis utilizes the thermal instability of organic waste, decomposing it under anaerobic or hypoxic conditions, thereby recovering fuel. Pyrolysis for solid waste treatment has reached industrial scale abroad. Composting is a process of biological stabilization of organic waste from municipal solid waste under controlled conditions, producing a highly effective fertilizer called compost. Compost can be used in agriculture to improve soil and increase yields.

[0003] Aerobic composting is carried out under aerobic conditions with the help of aerobic microorganisms. During the composting process, soluble organic matter in organic waste is absorbed by microorganisms through their cell walls and membranes; solid and colloidal organic matter first adheres to the outside of the microorganisms, and then is decomposed into soluble substances by extracellular enzymes secreted by the microorganisms, before penetrating into the cells. Through their life activities—oxidation-reduction and biosynthesis—microorganisms oxidize some of the absorbed organic matter into simple inorganic substances, releasing the energy needed for their growth and activity, and convert another portion of the organic matter into new cellular material, enabling microorganisms to grow and reproduce, producing more organisms. The remaining organic matter that cannot be degraded is partially converted into humus. Ultimately, the organic waste is mineralized and humified, while the high temperature (60-70℃) generated during the composting process kills pathogens, insect eggs, and weed seeds brought in with the raw materials, achieving the goal of harmlessness.

[0004] During the aerobic composting process of placing organic waste inside a fermentation tank, oxygen needs to be introduced into the organic waste through aeration pipes to maintain an oxygen concentration of over 10%, which facilitates the decomposition of organic matter and the reproduction of microorganisms. However, during the fermentation process, in order to accelerate the decomposition efficiency and composting effect, the organic waste needs to be turned over. However, the aeration pipes at the bottom of the fermentation tank are located in the organic waste pile, which prevents workers from using machinery to turn over the organic waste, increasing the labor intensity of workers and reducing composting efficiency.

[0005] Therefore, it is necessary to provide a new solid waste treatment device to solve the above problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a solid waste treatment device that facilitates the use of mechanical turning of organic waste and accelerates composting efficiency.

[0007] To solve the above-mentioned technical problems, the solid waste treatment device provided by this utility model includes: a fermentation tank, which is composed of an aerobic fermentation tank and a bottom tank, and the aerobic fermentation tank and the bottom tank are separated by a partition; an internal sliding connection communication mechanism of the fermentation tank, the communication mechanism including a fixed rod, the fixed rod being slidably connected inside the fermentation tank, and a fixed head being fixedly connected to the top of the fixed rod; multiple elastic rods being fixedly connected to the side wall of the fixed head, and a geotextile layer being installed on the side wall of the elastic rod; multiple connecting rods being installed on the side wall of the fixed rod, and springs being installed inside the connecting rods, with one end of the spring connected to the side wall of the elastic rod.

[0008] Preferably, multiple hydraulic rods are installed on the side wall and inside the bottom tank, the side wall of the fermentation tank is rotatably connected to the tank door, and the two ends of the hydraulic rods are rotatably connected to the tank door and the bottom tank.

[0009] Preferably, multiple aeration pipes are installed inside the bottom of the pool, and the aeration pipes are connected to the fixed rod through flexible hoses.

[0010] Preferably, the bottom end of the fixed rod is fixedly connected to a support rod, a connecting frame is fixedly installed between adjacent support rods, and the top end of the hydraulic rod inside the bottom pool is fixedly connected to the side wall of the connecting frame.

[0011] Preferably, the sidewall of the partition is fixedly connected to multiple fixing sleeves, the inside of the fixing sleeves is slidably connected to the support rod and the geotextile layer, and the bottom end of the support rod is installed with a funnel.

[0012] Preferably, the partition has multiple grooves inside, and the geotextile layer is slidably connected inside the grooves.

[0013] Preferably, the top ends of the support rod and the fixing sleeve are frustum-shaped, and the top end of the support rod is fixedly connected to multiple elastic rods.

[0014] Compared with related technologies, the solid waste treatment device provided by this utility model has the following beneficial effects:

[0015] This utility model provides a solid waste treatment device. When solid organic waste undergoes aerobic composting inside the fermentation tank, the hydraulic rod inside the bottom tank operates, driving the fixed rod upward. The fixed rod then drives the hemispherical fixed head upward into the solid organic waste. The fixed head drives the elastic rod upward. When the spring slides out from the chute, the spring extends, pushing the elastic rod outward to expand and bend, opening the surface of the geotextile layer and increasing the contact area between the geotextile layer and the solid organic waste. This facilitates air penetration through the geotextile layer into the solid organic waste. Air enters the solid organic waste from different directions, increasing the oxygen content inside the solid organic waste and accelerating the fermentation efficiency. Furthermore, excess water generated during the fermentation process permeates the geotextile layer. The geotextile layer enters the bottom pool to prevent the solid organic waste from having excessively high moisture content, which is beneficial for the fermentation of the solid organic waste. When it is necessary to turn the solid organic waste, the hydraulic rod operates to drive the fixing rod and the fixing head downwards. The geotextile layer enters the bottom pool along the chute, and the spring is pressed into the connecting rod, which facilitates the bending of the elastic rod into the chute. As the spring moves downwards and slides out of the chute, the spring extends and pushes the elastic rod to bend and expand outwards inside the bottom pool, so that the elastic rod is located in an arc shape inside the bottom pool, which facilitates the compression and deformation of the elastic rod by the chute into the bottom pool. The fixing head moves into the chute to close the chute and facilitates workers to use machinery to turn the solid organic waste inside the fermentation tank, reducing the workload of workers.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 , Figure 1 A schematic diagram of a preferred embodiment of the solid waste treatment device provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the fermentation tank. Figure 3 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 4 for Figure 3The diagram shows a top view of the geotextile layer structure. The solid waste treatment device includes: a fermentation tank 2, which consists of an aerobic fermentation tank 21 and a bottom tank 22, separated by a partition 24; an internal sliding connection mechanism 7, including a fixed rod 71, which is slidably connected to the interior of the fermentation tank 2; the top of the fixed rod 71 has multiple through holes 72; a fixed head 73 is fixedly connected to the top of the fixed rod 71; multiple elastic rods 74 are fixedly connected to the side wall of the fixed head 73, and a geotextile layer 75 is installed on the side wall of the elastic rods 74; multiple connecting rods 77 are installed on the side wall of the fixed rod 71, and the connecting rods 77... An internal spring 76 is installed, with one end of the spring 76 connected to the side wall of the elastic rod 74. When the solid organic waste 1 undergoes aerobic composting inside the fermentation tank 2, the hydraulic rod 3 inside the bottom tank 22 operates. The hydraulic rod 3 drives the fixed rod 71 to move upward, and the fixed rod 74 drives the fixed head 73, which has a hemispherical top, to move upward into the solid organic waste 1. The fixed head 73 drives the elastic rod 74 to move upward. When the spring 76 slides out from inside the chute 25, the spring 76 extends and pushes the elastic rod 74 to expand and bend outward, opening up the surface of the geotextile layer 75 and increasing the contact between the geotextile layer 75 and the solid organic waste. The contact area between the waste materials 1 facilitates air penetration through the geotextile layer 75 into the interior of the solid organic waste 1. Air enters the interior of the solid organic waste 1 from different directions, increasing the oxygen content and accelerating the fermentation efficiency. Furthermore, excess water generated during the fermentation process penetrates through the geotextile layer 75 into the bottom tank 22, preventing excessive moisture content and promoting fermentation. When it is necessary to turn the solid organic waste 1, the hydraulic rod 3 operates, driving the fixing rod 71 and the fixing head 73 downwards, and the geotextile layer 75 enters the bottom tank 22 along the chute 25. Inside the bottom pool 22, the spring 76 is pressed into the connecting rod 77, facilitating the bending of the elastic rod 74 into the groove 25. As the spring 76 moves downward and slides out of the groove 25, the spring 76 extends, pushing the elastic rod 74 to bend and expand outward within the bottom pool 22, so that the elastic rod 74 is located in an arc shape inside the bottom pool 22. This facilitates the compression and deformation of the elastic rod 74 by the groove 25 into the bottom pool 22. The fixing head 74 moves into the groove 25, sealing the groove 25 and making it easier for workers to mechanically turn over the solid organic waste inside the fermentation tank 2, reducing the workload of workers.

[0023] Multiple hydraulic rods 3 are installed on the side wall and inside the bottom pool 22. The side wall of the fermentation tank 2 is rotatably connected to the door 23, and the two ends of the hydraulic rods 3 are rotatably connected to the door 23 and the bottom pool 22. In order to facilitate the extension and retraction of the hydraulic rods 3 on the outside of the bottom pool 22, the door 23 is driven to rotate on the side wall of the fermentation tank 21, thereby closing and opening the fermentation tank 21, so as to facilitate the entry and exit of solid organic waste 1 inside the fermentation tank 21.

[0024] Multiple aeration pipes 4 are installed inside the bottom of the bottom pool 22, and the aeration pipes 4 are connected to the fixed rod 71 through the hose 41. In order to facilitate the connection between the air compressor and the aeration pipes 4, air is quickly delivered into the interior of the aeration pipes 4 and then into the interior of the fixed rod 71 through the hose 41.

[0025] The bottom end of the fixed rod 71 is fixedly connected to the support rod 5, and the connecting frame 6 is fixedly installed between adjacent support rods 5. The top end of the hydraulic rod 3 inside the bottom pool 22 is fixedly connected to the side wall of the connecting frame 6. In order to facilitate the movement of the hydraulic rod 3 inside the bottom pool 22, the hydraulic rod 3 drives the connecting frame 6, the support rod 5 and the fixed rod 71 to move up and down.

[0026] Multiple fixing sleeves 52 are fixedly connected to the side wall of the partition 24. The inside of the fixing sleeve 52 is slidably connected to the support rod 5 and the geotextile layer 75, and multiple elastic rods 74 are fixedly connected to the top of the support rod 5. When the fixing rod 5 moves up and down, the fixing rod 5 and the geotextile layer 75 slide inside the fixing sleeve 52. The fixing sleeve 52 guides the movement of the fixing rod 5 and the fixing rod 71. The top of the fixing sleeve 52 is frustum-shaped. The fixing sleeve 52 scrapes out the impurities adhering to the surface of the geotextile layer 75, reducing the impurities on the surface of the geotextile layer 75. The top of the support rod 5 is frustum-shaped, and a funnel 51 is installed at the bottom of the support rod 5 to facilitate the water inside the geotextile layer 75 to slide down the side wall of the support rod 5 and the funnel 51 into the interior of the bottom pool 22, reducing the water content inside the solid organic waste 1.

[0027] The partition 24 has multiple grooves 25 inside, and the geotextile layer 75 is slidably connected inside the grooves 25. In order to facilitate the separation of the bottom pool 22 from the aerobic fermentation pool 21 by the partition 24, the geotextile layer 75 passes through the grooves 25 and enters the interior of the aerobic fermentation pool 21.

[0028] The working principle of this utility model is as follows: When solid organic waste 1 is aerobically composted inside the fermentation tank 2, the hydraulic rod 3 is connected to an external power source, and the aeration pipe 4 is connected to an air compressor. The air compressor is connected to the aeration pipe 4, and air is quickly delivered into the interior of the aeration pipe 4, and then enters the interior of the fixing rod 71 through the hose 41. The hydraulic rod 3 inside the bottom tank 22 is opened, and the hydraulic rod 3 drives the connecting frame 6, the support rod 5, and the fixing rod 71 to move upward. The fixing rod 74 drives the fixing head 73, which has a hemispherical top, to move upward into the interior of the solid organic waste 1. The fixing head 73 drives the elastic rod 74 to move upward. When the spring 76 slides out from inside the chute 25, the spring 76 extends and pushes the elastic rod 74 to expand and bend outward, opening up the surface of the geotextile layer 75 (as shown in the attached figure). Figure 3 As shown, this increases the contact area between the geotextile layer 75 and the solid organic waste 1. Air enters the interior of the geotextile layer 75 through the through-hole 72, facilitating air penetration into the solid organic waste 1. Air enters the solid organic waste 1 from different directions and angles, increasing the oxygen content and accelerating fermentation efficiency. Excess water generated during fermentation penetrates the geotextile layer 75 into the bottom pool 22, preventing excessive moisture content and promoting fermentation. When the solid organic waste 1 needs to be turned, the hydraulic rod 3 inside the bottom pool 22 operates, driving the fixing rod 71 and the fixing head 73 downwards. The geotextile layer 75 enters the bottom pool 22 along the chute 25, and the spring 76 is pressed into the connecting rod 7. The interior of the 71st floor allows the elastic rod 74 to bend and enter the interior of the chute 25. As the spring 76 moves downward, it slides out of the chute 25. The spring 76 extends and pushes the elastic rod 74 to bend and expand outward inside the bottom pool 22, so that the elastic rod 74 is located in an arc shape inside the bottom pool 22. This facilitates the compression and deformation of the elastic rod 74 by the chute 25 into the bottom pool 22. The fixed head 74 moves into the interior of the chute 25, sealing the chute 25 and facilitating the use of machinery to turn over the solid organic waste 1 inside the fermentation tank 2, reducing the workload of the workers. After the aerobic composting of the solid organic waste 1 is completed, the hydraulic rod 3 on the outside of the bottom pool 22 is opened. The hydraulic rod 3 drives the box door 23 to rotate downward on the side wall of the fermentation tank 21, opening the fermentation tank 21 and facilitating the discharge of the fermented solid organic waste 1 from the fermentation tank 21.
