Description

Technical Field

[0001] This application relates to the technical field of organic fertilizer production equipment, and in particular to a segmented aeration intelligent composting reactor. Background Technology

[0002] Composting refers to the controlled biochemical process of converting degradable organic matter in solid waste into stable humus using microorganisms widely found in nature. Composting is a process of producing organic fertilizer, which is rich in nutrients and has a long-lasting and stable effect. It also promotes the formation of soil particle structure, increasing the soil's water retention, heat retention, aeration, and fertilizer retention capacity. Furthermore, when used in combination with chemical fertilizers, it can compensate for the shortcomings of chemical fertilizers, such as the lack of nutrient diversity and the long-term degradation of soil compaction and reduced water and fertilizer retention capacity caused by the sole use of chemical fertilizers. For example, Chinese patent document CN217052088U discloses a closed continuous dynamic composting reactor, including a closed frame box. The closed frame box has a feed hopper, a drum fermentation chamber, and a discharge chamber arranged independently in sequence. The upper end of the closed frame box has a raw material inlet communicating with the feed hopper, and the lower end has a clinker outlet communicating with the discharge chamber. A spiral propeller is installed in the feed hopper, and a solid screen with a blade structure is installed on the side of the feed hopper away from the raw material inlet. The end of the feed hopper away from the raw material inlet is connected to the drum fermentation chamber. The spiral propeller is used to push the organic solid waste input from the raw material inlet to the end of the feed hopper away from the raw material inlet, and into the feed port of the drum fermentation chamber; the drum fermentation chamber is rotatably installed in the sealed frame box, and several lifting plates are provided on the inner wall of the drum fermentation chamber; a bidirectional biaxial stirring and propulsion device is provided in the drum fermentation chamber, and a certain gap is reserved between the bidirectional biaxial stirring and propulsion device and the lifting plates; the bidirectional biaxial stirring and propulsion device is used for the surrounding mixing of materials in the drum fermentation chamber and the return of the compost, and pushes the composted compost through the discharge port of the drum fermentation chamber to the discharge chamber.

[0003] In the aforementioned technologies, the rotating shaft can drive the fixed plate to rotate, and the fixed plate can mix the compost and catalyst inside the tank. However, during the mixing process, since the compost raw materials and catalyst are not evenly distributed along the length of the rotating shaft after being added to the tank, the mixing time needs to be increased to make the compost and catalyst inside the tank more evenly mixed. Increasing the mixing time will reduce the production efficiency of compost, and at the same time, the electricity required to mix the same amount of compost will also increase, thus causing a waste of resources. Summary of the Invention

[0004] This application provides a segmented aeration intelligent composting reactor, which aims to solve the problem of low mixing efficiency of compost and catalyst in related technologies.

[0005] The segmented aeration intelligent composting reactor provided in this application adopts the following technical solution: A segmented aeration intelligent composting reactor includes a frame and a composting reactor housing mounted on the frame. The composting reactor housing is equipped with a stirring assembly for mixing compost materials. The stirring assembly includes a stirring shaft rotatably connected to the composting reactor housing and a first helical blade and a second helical blade mounted on the stirring shaft. The outer diameter of the first helical blade is larger than the outer diameter of the second helical blade. One end of the second helical blade is fixed to the stirring shaft, and the other end is fixedly mounted with an installation assembly. The installation assembly includes an installation rod fixed to the second helical blade and an installation block fixed to the installation rod. The installation block is slidably connected to the stirring shaft along its length, and the stirring shaft is equipped with a drive assembly for reciprocating movement of the installation block on the stirring shaft.

[0006] By adopting the above technical solution, when mixing compost and catalyst, the first and second helical blades are driven to rotate by the stirring shaft, thereby achieving mixing of compost and catalyst. During the mixing process, the drive assembly drives the mounting block to move back and forth along the length of the stirring shaft. As the mounting block moves the stirring shaft, it also drives the mounting rod to move. The mounting rod drives one end of the second helical blade to move towards the other end. During the movement of the second helical blade, it pushes the compost and catalyst to move back and forth along the length of the stirring shaft. At the same time, the first helical blade pushes the compost and catalyst to rotate circumferentially along the stirring shaft. This can improve the mixing effect of compost and catalyst in the compost reactor tank and thus improve the mixing efficiency of compost and catalyst.

[0007] Optionally, the drive assembly includes a drive screw that passes through the stirring shaft and a drive motor that is fixed to the stirring shaft. The output shaft of the drive motor is fixedly connected to the drive screw, and the drive screw is rotatably connected to the stirring shaft. The drive screw passes through the mounting block and is threadedly connected to the mounting block.

[0008] By adopting the above technical solution, the drive motor drives the drive screw to rotate, and the drive screw drives the mounting block to move back and forth along the length of the stirring shaft. Then, one end of the second spiral blade can move to the other end, which facilitates the movement of compost in the composting reactor box.

[0009] Optionally, one end of the first spiral blade is fixed to the stirring shaft, and the other end is provided with a moving rod. The moving rod is provided with a connecting component, which is used to connect the moving rod and the mounting block, so that the moving rod and the mounting block move simultaneously. The first spiral blade is provided with an abutting component for abutting against the inner wall of the composting reactor box.

[0010] By adopting the above technical solution, when cleaning the material inside the composting reactor box, the abutting component on the first spiral blade abuts against the inner wall of the composting reactor box, and then the moving rod and the mounting block are connected by the connecting component. During the process of the drive screw moving the mounting block, the moving rod can be moved at the same time. During the movement of the moving rod, one end of the first spiral blade moves to the other end. Then the abutting component can push the compost on the bottom wall of the composting reactor box towards the discharge port, thereby achieving the purpose of facilitating the cleaning of the internal compost.

[0011] Optionally, the abutment component includes a spiral air-filling groove formed on the first spiral blade and a sealing elastic strip provided on the first spiral blade. The first spiral blade is provided with an opening facing the inner wall of the composting reactor box. The opening is connected to the spiral air-filling groove, and the sealing elastic strip is used to seal the opening. The composting reactor box is provided with an air-filling component for filling or evacuating air into the spiral air-filling groove. When air is filled into the spiral air-filling groove, the sealing elastic strip expands and is stretched, and the expanded sealing elastic strip abuts against the inner wall of the composting reactor box.

[0012] By adopting the above technical solution, when residual materials cannot be cleaned from the composting reactor box, air is injected into the spiral air-filling groove through the air-filling component. At this time, the sealing elastic strip expands and is stretched, and the expanded sealing elastic strip abuts against the inner wall of the composting reactor box, thereby pushing the residual compost material to move towards the discharge port.

[0013] Optionally, the connecting assembly includes a movable block fixed on the movable rod and a connecting screw rotatably connected to the movable block. The mounting block has a threaded hole for threaded connection with the connecting screw. The connecting screw slides on the stirring shaft along the length direction of the stirring shaft. The stirring shaft is provided with a control assembly for driving the connecting screw to move into the threaded hole.

[0014] By adopting the above technical solution, when the first helical blade needs to move to the other end, the control component drives the connecting screw to move, and then the connecting screw and the threaded hole on the mounting block are threaded together. At this time, the moving block will move simultaneously during the movement of the mounting block, thereby making it easier to move one end of the first helical blade closer to the other end.

[0015] Optionally, the control assembly includes a control rod slidably connected to the moving block and a control block fixed to the control rod. One end of the control rod extends out of the stirring shaft and is connected to the control block. The control rod is slidably connected to the stirring shaft along the length of the control shaft. A control groove for inserting the control rod is provided on the end face of the connecting screw.

[0016] By adopting the above technical solution, when it is necessary to drive the connecting screw to move closer to the mounting block, push the control rod, the control rod moves into the control groove, and then push the control rod to move. At the same time, rotate the control rod, the rotation of the control rod drives the connecting screw to rotate, and then the connecting screw and the threaded hole are threadedly connected, thereby achieving the purpose of facilitating the rotation and movement of the connecting screw.

[0017] Optionally, the movable block is provided with a mounting groove, and a return spring is provided in the mounting groove. The return spring is sleeved on the connecting screw, one end of the return spring is fixed to the connecting screw, and the other end abuts against the inner wall of the mounting groove.

[0018] By adopting the above technical solution, when the control rod is pushed into the control slot, the return spring is compressed. After the connecting screw and the threaded hole are connected, the control rod is released, and the connecting screw is pushed to reset under the action of the return spring.

[0019] Optionally, a cleaning ring is fixedly installed on the moving rod, and a rubber ring is fixedly installed on the outer ring of the cleaning ring, with the rubber ring abutting against the inner wall of the composting reactor box.

[0020] By adopting the above technical solution, when the moving rod and the installation rod move simultaneously, the moving rod drives the cleaning ring to move, and then the inner wall of the compost reactor box is cleaned through the rubber ring.

[0021] Optionally, the aeration assembly includes an aeration ring fixed on the stirring shaft, an mounting ring fixed inside the composting reactor housing, an aeration pipe for connecting with the aeration ring, and an air pump installed on the composting reactor housing. The air pump is connected to the aeration pipe, and the aeration ring is connected to the spiral aeration groove.

[0022] By adopting the above technical solution, the air pump inflates the air ring through the air inflator pipe, and then the gas in the air ring enters the spiral air inflator groove, which in turn causes the sealing elastic strip to expand.

[0023] Optionally, the stirring shaft is provided with a plurality of support components for supporting the first helical blade and the second helical blade. The support components include a support rod slidably connected to the stirring shaft and a support block fixed to the first helical blade. The support rod is fixed to the second helical blade and a limit groove is formed on the support rod. At the same time, a limit block for inserting into the limit groove is fixedly installed on the support block.

[0024] By adopting the above technical solution and by setting up support rods and support blocks, the first and second helical blades can be made more stable when rotating and mixing.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During the movement of the installation block and the stirring shaft, the installation rod will also move. The installation rod will move one end of the second spiral blade to the other end. During the movement of the second spiral blade, the compost will be pushed to move back and forth along the length of the stirring shaft. At the same time, the first spiral blade will push the compost and catalyst to rotate around the stirring shaft. This will make the compost and catalyst in the compost reactor box mix better, and thus improve the mixing efficiency of the compost and catalyst.

[0026] 2. The air-filling component inflates the spiral air-filling groove. At this time, the sealing elastic strip expands and is stretched, and the expanded sealing elastic strip abuts against the inner wall of the composting reactor box, which will push the residual compost towards the discharge port.

[0038] The following combination Figures 1-8 This application will be described in further detail.

[0039] This application discloses a segmented aeration intelligent composting reactor. (Refer to...) Figures 1 to 3 A segmented aeration intelligent composting reactor includes a frame 01 and a composting reactor housing 02 mounted on the frame 01. A cover plate is installed on the composting reactor housing 02 to seal the composting reactor housing 02. A stirring assembly 1 is provided inside the composting reactor housing 02 to stir and mix compost and catalyst. The stirring assembly 1 includes a stirring shaft 11 rotatably connected inside the composting reactor housing 02 and a first spiral blade 12 and a second spiral blade 13 mounted on the stirring shaft 11. The outer diameter of the first spiral blade 12 is larger than the outer diameter of the second spiral blade 13, and the first spiral blade 12 and the second spiral blade 13 rotate in opposite directions.

[0040] An aeration assembly is installed on the compost reactor housing 02. This assembly aerates the compost within the housing, thereby increasing the reaction rate between the compost and the catalyst. Since the aeration assembly is existing technology, its specific structure will not be described in detail in this embodiment.

[0041] Reference Figures 1 to 3One end of the first spiral blade 12 is fixed to the stirring shaft 11, and the other end is provided with a moving rod 05. The moving rod 05 is slidably connected to the stirring shaft 11 along the length direction of the stirring shaft 11. One end of the second spiral blade 13 is fixed to the stirring shaft 11, and the other end is provided with a mounting component 2. At the same time, a driving component 3 is provided on the stirring shaft 11. The driving component 3 is used to drive the mounting component 2 to move. Then, the mounting component 2 will drive one end of the second spiral blade 13 to move to the other end. At the same time, a connecting component 4 is provided on the moving rod 05. The connecting component 4 is used to connect the moving rod 05 and the mounting component 2. Then, the mounting component 2 and the moving rod 05 can slide on the stirring shaft 11 simultaneously.

[0042] Reference Figures 1 to 3 A rotary motor 03 and a reducer 04 are installed on the frame 01. The output shaft of the reducer 04 is fixedly connected to the stirring shaft 11. The output shaft of the rotary motor 03 is connected to the input shaft of the reducer 04 through a belt. When the rotary motor 03 rotates, it will drive the input shaft of the reducer 04 to rotate under the action of the belt, and finally cause the output shaft of the reducer 04 to rotate, which in turn drives the stirring shaft 11 to rotate.

[0043] Reference Figures 2 to 4 The mounting assembly 2 includes a mounting block 21 slidably connected to the stirring shaft 11 and a mounting rod 22 fixed to the mounting block 21. The mounting rod 22 is fixed to the end of the second spiral blade 13. Then, the drive assembly 3 on the compost reactor housing 02 is used to drive the mounting block 21 to move along the length of the stirring shaft 11. The drive assembly 3 includes a drive screw 31 rotatably connected to the stirring shaft 11 and a drive motor 32 fixed to the stirring shaft 11. One end of the drive screw 31 extends out of the end face of the stirring shaft 11 and is then fixedly connected to the output shaft of the drive motor 32. The drive screw 31 passes through... The mounting rod 22 and the mounting block 21 are threaded together. The drive motor 32 drives the drive screw 31 to rotate, which in turn drives the mounting block 21 to slide on the mixing shaft 11. This causes one end of the second spiral blade 13 to move towards the other end. During this movement, the second spiral blade 13 pushes the compost material back and forth along the length of the mixing shaft 11. Simultaneously, the first spiral blade 12 and the second spiral blade 13 rotate around the mixing shaft 11, thereby accelerating the mixing of the compost and improving its mixing efficiency. To facilitate the sliding of the mounting rod 22 and the mounting block 21 on the mixing shaft 11, a groove is provided on the mixing shaft 11. The groove extends along the length of the mixing shaft 11 and passes through the mixing shaft 11 in a direction perpendicular to its axis.

[0044] Reference Figures 2 to 8A support assembly 5 is provided on the stirring shaft 11. The support assembly 5 is used to support the second spiral blade 13 and the first spiral blade 12. The support assembly 5 includes a support rod 51 slidably connected to the stirring shaft 11 and a support block 52 fixed to the first spiral blade 12. The support rod 51 is fixed to the first spiral blade 12 and a limiting groove 6 is formed on the support rod 51. The limiting groove 6 passes through the support rod 51 along the length direction of the stirring shaft 11. A limiting block 61 for insertion into the limiting groove 6 is fixedly installed on the support block 52. When the first spiral blade 12 and the second spiral blade 13 are both at their natural length, the limiting block 61 is in the limiting groove 6. At this time, the first spiral blade 12 can be supported by the support rod 51 and the support block 52. When the second spiral blade 13 is compressed, the limiting block 61 on the support block 52 disengages from the limiting groove 6. To improve the stability of the first helical blade 12, a support shaft 10 is rotatably connected to the inner wall of the composting reactor box 02. Both ends of the support shaft 10 rotate on the inner wall of the composting reactor box 02. The support shaft 10 and the stirring shaft 11 are arranged in parallel, and the first helical blade 12 is slidably connected to the support shaft 10.

[0045] Multiple support components 5 are provided, and these support components 5 are evenly spaced along the length of the stirring shaft 11, which can improve the strength of the first helical blade 12 and the second helical blade 13. When the drive component 3 drives the mounting rod 22 on the second helical blade 13 to move, the support rod 51 on the second helical blade 13 will also slide on the stirring shaft 11 at the same time.

[0046] Reference Figures 2 to 4 The connecting component 4 is used to connect the mounting block 21 and the moving rod 05. The connecting component 4 includes a moving block 41 fixed on the moving rod 05 and a connecting screw 42 slidably connected to the moving block 41. The connecting screw 42 can also rotate on the moving block 41. The connecting screw 42 is sleeved on the driving screw 31. A threaded hole 43 is provided on the mounting block 21 for threaded connection with the connecting screw 42. At the same time, a control component 7 is provided on the stirring shaft 11 for driving the moving and rotating of the connecting screw 42. When the control component 7 makes the connecting screw 42 and the threaded hole 43 threadedly connected, the moving block 41 is fixed on the mounting block 21. While the driving screw 31 drives the mounting block 21 to move, it can also drive the moving block 41 to move. Then, the moving rod 05 and one end of the first spiral blade 12 are driven to move to the other end through the moving block 41.

[0047] Reference Figures 3 to 10A mounting groove 62 is provided on the movable block 41, and a return spring 63 is provided in the mounting groove 62. One end of the return spring 63 abuts against the inner wall of the mounting groove 62, and the other end is fixed to the connecting screw 42. The return spring 63 is used to drive the connecting screw 42 to move away from the threaded hole 43. In the initial state, the return spring 63 causes the connecting screw 42 to disengage from the threaded hole 43. Then, when the mounting block 21 and the movable block 41 need to be connected, the control component 7 drives the connecting screw 42 to move and rotate, so that the connecting screw 42 and the threaded hole 43 are threadedly connected, and the return spring 63 is in a compressed state. When the connecting screw 42 and the threaded hole 43 need to be disengaged, the control component 7 drives the connecting screw 42 to rotate in the opposite direction, and the return spring 63 will push the connecting screw 42 to move in the opposite direction, thereby facilitating the disengagement of the connecting screw 42 and the threaded hole 43.

[0048] Reference Figures 3 to 10 The control component 7 includes a control rod 71 slidably connected to the moving block 41 and a control block 72 fixed to the control rod 71. One end of the control rod 71 extends out of the stirring shaft 11 and is connected to the control block 72. The control rod 71 is slidably connected to the stirring shaft 11 along its length. A control groove 73 for inserting the control rod 71 is provided on the end face of the connecting screw 42. In this embodiment, both the portion of the control rod 71 that inserts into the control groove 73 and the cross-section of the control groove 73 are designed to be hexagonal. When the end of the control rod 71 is inserted into the control groove 73, the control block 72 can... The control rod 71 rotates, which in turn drives the connecting screw 42 to rotate. Since both the control rod 71 and the connecting screw 42 are slidably connected to the moving block 41, pushing the control block 72 causes it to move the control rod 71 closer to the connecting screw 42. Then, the end of the control rod 71 moves into the control groove 73, and the connecting screw 42 moves to the opening of the threaded hole 43. Finally, the connecting screw 42 and the threaded hole 43 on the mounting block 21 are threadedly connected. During the movement of the mounting block 21, the moving block 41 can be moved simultaneously. To facilitate the installation of the control assembly 7, the diameter of the end of the stirring shaft 11 used for installing the control assembly 7 is larger than the diameter of the compost reactor housing 02 (e.g., ...). Figures 4 to 10 (As shown).

[0049] Reference Figure 2 Figure 10There is a certain gap between the first spiral blade 12 and the inner wall of the composting reactor box 02, which can prevent the first spiral blade 12 from hitting the inner wall of the composting reactor box 02 when it rotates. When it is necessary to discharge, the rotation of the first spiral blade 12 can push the compost towards the discharge port. When the discharge port is opened, some compost will be discharged from the discharge port. Since there is a certain gap between the first spiral blade 12 and the inner wall of the composting reactor box 02, some compost will remain at the bottom of the composting reactor box 02, which needs to be cleaned manually by the staff. In this embodiment, an abutment component 8 is provided on the first spiral blade 12. When cleaning the compost in the composting reactor box 02, the abutment component 8 abuts against the bottom wall of the composting reactor box 02, and then pushes the compost at the bottom of the composting reactor box 02 towards the discharge port, thereby making it easier to clean the compost in the composting reactor box 02.

[0050] Reference Figures 2 to 10 The abutment component 8 includes a spiral air-filling groove 81 formed on the first spiral blade 12 and a sealing elastic strip 82 provided on the first spiral blade 12. In this embodiment, the sealing elastic strip 82 can be made of a wear-resistant and anti-aging material, such as butadiene rubber (BR), styrene-butadiene rubber (SBR), or polyurethane rubber (PU). The first spiral blade 12 is provided with an opening facing the inner wall of the composting reactor box 02. The opening is connected to the spiral air-filling groove 81, and the sealing elastic strip 82 is used to seal the opening. The composting reactor box 02 is provided with an air-filling component 9 for filling or evacuating air into the spiral air-filling groove 81. When air is filled into the spiral air-filling groove 81, the sealing elastic strip 82 expands and is stretched, and the expanded sealing elastic strip 82 abuts against the inner wall of the composting reactor box 02. When air is evacuated into the spiral air-filling groove 81, the expanded sealing elastic strip 82 returns to its original state, and at this time the sealing elastic strip 82 no longer abuts against the inner wall of the composting reactor box 02.

[0051] Reference Figures 2 to 10 The aeration assembly 9 includes an aeration ring 91 fixed on the stirring shaft 11, an mounting ring 92 fixed inside the composting reactor housing 02, an aeration pipe 93 for connecting to the mounting ring 92, and an air pump (not shown in the figure) installed on the composting reactor housing 02. The air pump is connected to the aeration pipe 93, and the aeration ring 91 is connected to the spiral aeration groove 81. The aeration ring 91 is rotatably connected to the mounting ring 92, and the aeration ring 91 and the mounting ring 92 are connected. Then, the air pump inflates the mounting ring 92 through the aeration pipe 93. The gas in the mounting ring 92 enters the aeration ring 91, and the gas in the aeration ring 91 enters the spiral aeration groove 81, which causes the sealing elastic strip 82 to expand. The expanded sealing elastic strip 82 abuts against the inside of the composting reactor housing 02.

[0052] Reference Figure 1 and Figure 10A cleaning ring 64 is fixedly installed on the moving rod 05. Two moving rods 05 are provided on the cleaning ring 64, and a rubber ring 65 is fixedly installed on the outer ring of the cleaning ring 64. The rubber ring 65 abuts against the inner wall of the composting reactor box 02. When the moving rod 05 drives one end of the first spiral blade 12 to move, it can also drive the cleaning ring 64 to move. Then the cleaning ring 64 can push the compost in the composting reactor box 02 towards the discharge port, thereby facilitating the cleaning of the compost on the inner wall of the composting reactor box 02.

[0053] The implementation principle of a segmented aeration intelligent composting reactor according to an embodiment of this application is as follows: When cleaning the compost, the rotating motor 03 and the reducer 04 drive the stirring shaft 11 to rotate. The rotation of the stirring shaft 11 drives the first spiral blade 12 and the second spiral blade 13 to rotate, mixing the compost and catalyst in the composting reactor box 02. At the same time, the drive assembly 3 drives the drive screw 31 to rotate. When the drive screw 31 rotates, it drives the mounting block 21 to move. The mounting block 21 drives the mounting rod 22 to move. The mounting rod 22 drives one end of the second spiral blade 13 to move to the other end. The second spiral blade 13 is gradually compressed. During the reciprocating movement of the second spiral blade 13, it pushes the compost and catalyst in the composting reactor box 02 to move laterally. Under the action of the first spiral blade 12, the mixing effect of the compost in the composting reactor box 02 can be improved, and the mixing speed of the compost and catalyst can also be increased.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
