Description

Technical Field

[0001] This invention relates to the field of waste resource utilization technology, specifically a combined three-dimensional composting device. Background Technology

[0002] The technological development of solid waste composting equipment stems from the practical difficulties of traditional composting methods, such as low efficiency and high pollution risks. Early composting relied on natural fermentation, which was time-consuming and prone to producing foul odors and leachate pollution. Low levels of mechanization also limited its large-scale application. With increasingly stringent environmental standards and growing demands for resource recycling, modern composting equipment optimizes the microbial metabolic environment by introducing systems for temperature control, oxygen supply, and mixing. This shortens the cycle while reducing pollution emissions, transforming solid waste into recyclable fertilizer and largely achieving resource recovery, waste reduction, and harmlessness.

[0003] However, general composting equipment can only compost small quantities of solid waste. For larger quantities of solid waste, windrow composting, static composting, and trough composting are used. These composting methods involve piling up large amounts of waste for fermentation, and they also have problems such as large space occupation, difficulty in temperature control, uneven gas supply, long composting cycle, and difficulty in loading and unloading materials.

[0004] To address this, existing technology discloses a layered aerobic composting bin, including a bin body, a lid, and a base. The bin body is cylindrical, and the bin body and lid are connected by snap-fit ​​connections. An assembled partition is located above the base. Inside the bin body, a drawer-type honeycomb-perforated partition with multiple holes is provided. The lid has an air inlet and an insect screen, and an exhaust vent is located above the base. This device provides a layered aerobic composting bin with good aeration, ensuring sufficient oxygen inside the bin. The layered design guarantees the quality of the produced organic fertilizer, and operation is very convenient.

[0005] However, the device still has some obvious defects in use: although it achieves layered stacking composting, it cannot more accurately ensure the uniform fermentation of waste in different locations within the composting space, and the feeding and retrieval of materials within the device is inconvenient, making it unsuitable for large-scale composting sites. Summary of the Invention

[0006] The purpose of this invention is to provide a combined three-dimensional composting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A combined three-dimensional composting device includes: A fermentation frame, which is composed of a detachable base plate and side plates, is used as a filling container for fermentation bags; Fermentation bag, which is adapted to the size of the fermentation frame and placed into the fermentation frame.

A mobile stacking rack is composed of shelves, a main frame, and bidirectional air ducts. The mobile stacking rack has multiple stacking layers, and multiple fermentation frames can be stacked on each stacking layer. The bidirectional air ducts consist of a main air pipe and branch air pipes.

The vertical gas filling and releasing wall is provided with multiple sets of main pipe fitting mechanisms, which are the same number as the tracks of the fermentation shed and correspond one-to-one. The multiple main pipe fitting mechanisms are connected to the main gas pipeline installed in the wall, so that oxygen is pumped in or fermentation gas is pumped out through the main gas pipeline.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 The present invention provides a technical solution: Example 1: A combined three-dimensional composting device includes: Fermentation frame 1 is composed of a detachable base plate 2 and side plates 3, and is used as a filling container for fermentation bags 4. Fermentation bag 4 is adapted to the size of fermentation frame 1 and placed in fermentation frame 1. Fermentation bag 4 is a sealed and airtight bag structure. A two-way air tube 5 is inserted into fermentation bag 4. The mobile stacking rack 6 consists of a shelf 7, a main frame 8, and a bidirectional gas pipeline. The mobile stacking rack 6 has multiple stacking layers, and multiple fermentation frames 1 can be stacked on each stacking layer. The bidirectional gas pipeline consists of a main gas pipe 28 and a branch gas pipe 30. Gas is supplied to the fermentation bag 4 through the plug-in cooperation between the gas pipe connection port 9 on the branch gas pipe 30 and the bidirectional gas pipe 5. Both ends of the main gas pipe 28 are provided with a pipe opening cooperation mechanism 12 that cooperates with the main gas pipe 28 of the adjacent mobile stacking rack 6. Fermentation shed 10 is a retractable shed. A movable stacking rack 6 is arranged inside the fermentation shed 10. A temperature detection device 11 is also installed inside the fermentation shed 10.

[0022] This embodiment of a mobile, detachable aerobic composting device for solid waste that enables rapid decomposition includes a fermentation frame 1, fermentation bags 4, a mobile stacking rack 6, and a fermentation shed 10, as shown in the attached instruction manual. Figure 3 Included with instruction manual Figure 4 It can be seen that the fermentation frame 1 is composed of a base plate 2 and four side plates 3. The base plate 2 is made of plastic board. Five track wheels 14 are installed on the lower part of the plastic board, respectively set at the four corners and the center of the bottom of the base plate 2. Four frame strips 17 and four columns 18 are fixedly installed on the upper part of the base plate 2. The frame strips 17 and columns 18 are provided with insertion grooves. The side plates 3 are inserted and matched through the insertion grooves. The upper part of the base plate 2 encloses to form a topless fermentation frame 1. A bidirectional air pipe 5 is detachably installed in the fermentation frame 1. The bidirectional air pipe 5 is connected to the inside of the fermentation bag 4 through the aeration holes opened in the pipe wall, so as to carry out fermentation and gas filling operation inside the fermentation bag 4. In actual operation, oxygen is mostly filled into the fermentation bag 4 to carry out aerobic fermentation. In addition, in the anaerobic fermentation process, it is also necessary to pump out the waste gas produced by fermentation in time. Therefore, the bidirectional air pipe 5 also serves as a pumping mechanism for the fermentation gas produced in the sealed bag during the anaerobic fermentation process. As per the instruction manual Figure 2 It can be seen that the mobile stacking rack 6 consists of shelves 7, a main frame 8, bidirectional air ducts, and track wheels 14. The bidirectional air ducts include a main air pipe 29 and branch air pipes 30. The size of the main frame 8 is adapted to the size of the fermentation frame 1. The main frame 8 is made of high-strength steel and has a hot-dip galvanized anti-rust treatment. It is divided into three stacking layers by shelves 7. The spacing between each stacking layer is adapted to the height of the fermentation frame 1. Shelves 7 are made of thick patterned steel plates. Branch air pipes 30 are arranged directly above each stacking layer. Multiple air pipe connection ports 9 are provided on the branch air pipes 30. The air pipe connection ports 9 are connected to the bidirectional air pipes 5 by quick-release plug-in. The main air pipe 29 is fixed along the outside of the main frame 8 with clamps. The main air pipe 29 is inverted U-shaped and has pipe fitting machines at both ends. Structure 12 allows for quick connection of adjacent main air pipes 29 via the pipe fitting mechanism 12. Branch air pipes 30 are connected to the bidirectional air pipes 29. Each branch air pipe 30 is also equipped with an independent electrically controlled butterfly valve 19 for easy individual control of on / off. The main air pipes 29 and branch air pipes 30 adopt a PU hose structure. The track wheels 14 at the bottom of the mobile stacking rack 6 are also equipped with a braking mechanism to maintain the stability of the mobile stacking rack 6 under braking. The mobile stacking rack 6 is embedded into the fermentation shed track 16 via the track wheels 14 to guide the movement of the mobile stacking rack 6. The number of air pipe connection ports 9 is consistent with the number of fermentation frames 1 set on each stacking layer and corresponds one-to-one. The air pipe connection ports 9 are located directly above the fermentation frames 1 for easy connection with the bidirectional air pipes 5.

[0023] like Figure 1As shown, the fermentation shed 10 consists of an X-shaped scissor-type telescopic frame 20 with a telescopic structure, a tarpaulin 21, and a temperature detection device 11. The top of the scissor-type telescopic frame 20 is an arc-shaped arch beam with a slope of 15 degrees to facilitate drainage. The main frame is constructed of lightweight high-strength steel. The arc-shaped arch beams are spaced apart, and a crossbeam is installed under the arch beam. The two side columns are connected to the ends of the arch beam and the crossbeam. Diagonal support rods are installed at the connection between the columns and the crossbeams, and vertical support rods are installed between the arch beam and the crossbeam. The telescopic structure is a cross-link type, connecting each crossbeam. The cross-links are X-shaped hinges. A set of cross-links is installed in the middle of every two crossbeams at the top, and two sets of cross-links are installed in every two columns on the left and right sides. It is compact when contracted and fully extended when stretched. The length can be extended and retracted according to the amount of material, saving space. The tarpaulin 21 is made of wear-resistant and corrosion-resistant tarpaulin with a semi-transparent design. The fermentation shed track 16 is parallel to the telescopic direction of the shed body and extends outside the fermentation shed 10 to facilitate the movement of the mobile stacking rack 6 and the loading of materials.

[0024] During fermentation, different structural combinations are used depending on the type of fermentation. When anaerobic fermentation is required, the bidirectional air pipe 5 needs to be inserted into the fermentation bag 4 and the opening of the fermentation bag 4 needs to be tied tightly. At this time, it is not necessary to fill the fermentation bag 4 with fermentation gas. However, fermentation gas will be produced during anaerobic fermentation. If this gas is not discharged, it will cause the fermentation bag 4 to expand and affect the efficiency of anaerobic fermentation. Therefore, the fermentation gas produced needs to be discharged regularly through the main air pipe 29 and the branch air pipe 30 to ensure the normal progress of the anaerobic fermentation process. When aerobic fermentation is required, the fermentation bag 4 is not needed. At this time, it is only necessary to place the material to be fermented in the fermentation frame 1. Due to the mesh perforated structure of the side plate of the fermentation frame 1, the material can fully contact the air in the environment. At this time, the bidirectional air pipe 5 is inserted into the material pile, and the bidirectional air pipe 5 is quickly connected to the air pipe connection port 9 to perform the gas supply operation for the aerobic fermentation process, thereby ensuring the normal progress of aerobic fermentation. The above-mentioned exhaust or gas supply process is achieved by a bidirectional air pump connected to the main air pipe 29.

[0025] Example 2: A vertical gas filling and releasing wall 22 is also installed on one side of the fermentation shed 10. The vertical gas filling and releasing wall 22 is equipped with multiple sets of main pipe fitting mechanisms 13, which are the same number as the fermentation shed track 16 and correspond one-to-one. The multiple main pipe fitting mechanisms 13 are connected to the main gas pipe installed in the wall, so that oxygen is pumped in or fermentation gas is pumped out through the main gas pipe. The main pipe fitting mechanism 13 is magnetically adsorbed and fitted with the pipe fitting mechanism 12 of the main gas pipe 28 near the wall.

[0026] Both the pipe fitting mechanism 12 and the main pipe fitting mechanism 13 consist of a fixed block 23 and a telescopic movable block 24. The telescopic movable block 24 is telescopically inserted outside the fixed block 23 via a slide rod 25. A retraction spring is also fitted on the slide rod 25. The retraction spring is used to push the telescopic movable block 24 to move closer to the fixed block 23 without external force. Both the fixed block 23 and the telescopic movable block 24 have through holes in their middle. The through hole of the fixed block 23 is connected to the main air pipe 28. The periphery of the through holes of the fixed block 23 and the telescopic movable block 24 is connected by a corrugated pipe 26. An electromagnet adsorption coil is provided on the telescopic movable block 24. By energizing the electromagnet adsorption coil, it is made magnetic. The telescopic movable blocks 24 on adjacent main air pipes 28 are magnetically engaged under the action of magnetic adsorption force, thereby making adjacent main air pipes 28 interconnected. A sealing ring 27 is also provided on the end face of the magnetically engaged side of the telescopic movable block 24.

[0027] Buffer pads 28 are installed at both ends of the main frame 8 in the direction of movement and on the side of the vertical inflation / deflation wall 22 near the fermentation shed track 16.

[0028] In this embodiment, a vertical gas filling and releasing wall 22 is provided on one side of the fermentation shed 10. Multiple sets of main pipe fitting mechanisms 13, corresponding one-to-one in number to the number of tracks 16 in the fermentation shed, are provided on the vertical gas filling and releasing wall 22. (Refer to the appendix of the instruction manual.) Figure 1 Multiple main pipe fitting mechanisms 13 are connected to the main gas pipe inside the wall, thereby enabling centralized gas supply or exhaust through the main gas pipe. Both the main pipe fitting mechanism 13 and the pipe fitting mechanism 12 consist of a fixed block 23 and a telescopic movable block 24. The fixed block 23 is connected to the main gas pipe 28, which is connected to the through hole of the telescopic movable block 24 via a corrugated pipe 26. The telescopic movable block 24 moves closer to the fixed block 23 without external force. An electromagnet adsorption coil is installed inside the telescopic movable block 24. When energized, the telescopic movable block 24 generates magnetism, causing an opposite current to flow through the adjacent main gas pipe 28, thus causing the telescopic movable blocks 24 on both sides to be attracted by the magnetic force. Under the action of the buffer pads 28, they cooperate with each other to complete the connection of adjacent main air pipes 28. This process does not require manual insertion. It only requires the application of current to achieve automatic cooperation. The buffer pads 28 ensure that there is a reasonable distance between adjacent movable stacking racks 6 and between the movable stacking racks 6 and the vertical inflation / deflation wall 22. This distance is to prevent collision damage to the main pipe fitting mechanism 13 or the pipe fitting mechanism 12. When the buffer pads 28 are in contact with each other, a certain distance is formed between adjacent telescopic movable blocks 24. After the electromagnet adsorption coil is energized, the telescopic movable blocks 24 approach each other under the action of magnetism and complete the adsorption operation. When it is necessary to detach, it is only necessary to stop supplying power to the electromagnet coil set in the telescopic movable block 24.
