Description

Technical Field

[0001] This utility model relates to the field of environmental protection treatment technology, and in particular to a modular high-efficiency dry anaerobic fermenter. Background Technology

[0002] The modular high-efficiency dry anaerobic digester is a device used for anaerobic fermentation. Waste is temporarily stored and mixed in a mixing silo before being sent to the dry anaerobic reactor for anaerobic fermentation. The gas produced by fermentation is temporarily stored in a gas holder and then purified. Part of the gas can be reused for heating in the system, while excess biogas can be used to refine natural gas for external supply or for power generation and grid connection or district heating.

[0003] Existing technologies employ modular and standardized manufacturing methods, allowing for flexible configuration of interfaces between one or two tanks based on different installation locations and user needs. This design enables the equipment to be assembled and moved at will, making it suitable for various sites and production scales. It solves the problems of equipment idleness and waste caused by the immobility, non-assembly, and non-standardization of traditional fermentation tanks.

[0004] However, in practical applications, the particle size, viscosity, and moisture content of the fed organic waste are uneven. Larger particles and more viscous particles may accumulate at the feed inlet, especially when the particle diameter is close to or larger than the feed inlet pipe diameter, which can easily cause blockage, resulting in poor material feeding and affecting the normal operation of the fermenter and fermentation efficiency.

[0005] Therefore, this application provides a modular, high-efficiency dry anaerobic fermenter to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, high-efficiency dry anaerobic fermenter.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a modular high-efficiency dry anaerobic fermenter, comprising:

[0008] Fermentation tank body;

[0009] The feeding assembly is located on the top of the fermenter body. The feeding assembly includes a feed inlet fixed on the top of the fermenter body and a support plate fixed inside the feed inlet. A blade is fixedly connected to the top of the support plate. A main rotating component is provided on the support plate. A secondary rotating component is provided on the side of the support plate near the main rotating component. Rotating blades are fixedly connected to the side of the main rotating component and the secondary rotating component near the support plate.

[0010] A transmission assembly is located inside the feeding assembly and is used to drive the main rotating component and the auxiliary rotating component to rotate in different directions. The transmission assembly includes a rotating shaft located inside the support plate and a driving wheel fixedly connected to the rotating shaft near one end of the auxiliary rotating component. A rack is provided on the side of the auxiliary rotating component near the driving wheel. A driven wheel meshes between the driving wheel and the rack. The auxiliary rotating component is connected to the driving wheel via the rack, the driven wheel and the driving wheel.

[0011] In a preferred embodiment, a slider is fixedly connected to the side of the secondary rotating component and the main rotating component near the support plate, and the main rotating component and the secondary rotating component are slidably connected to the support plate through the slider.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it can effectively ensure the stability of slider one during rotation.

[0013] In a preferred embodiment, bearings are fixedly connected to one end of the rotating shaft near the feed inlet and the support plate, and the rotating shaft is rotatably connected to the feed inlet and the support plate through the bearings.

[0014] The beneficial effects of adopting the above-mentioned further solution are: it effectively ensures smooth and unobstructed rotation of the shaft, and at the same time, it greatly facilitates the separation operation between the shaft and the bearing.

[0015] In a preferred embodiment, a snap-fit ​​block is fixedly connected to the rotating shaft, and the rotating shaft is snapped into the drive wheel and the main rotating component through the snap-fit ​​block.

[0016] The advantages of adopting the above-mentioned further scheme are: it facilitates the rotation of the shaft to drive the drive wheel and the main rotating component, and it also facilitates the separation of the shaft from the drive wheel and the main rotating component.

[0017] In a preferred embodiment, a connecting member is fixedly connected between the drive wheel and the bearing.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: under the action of the connector, more reliable support and fixation can be obtained, thereby effectively improving its stability during rotation and reducing unnecessary shaking and deviation.

[0019] In a preferred embodiment, a motor is fixedly connected to one side of the feed inlet, and a connecting post is provided on the side of the output end of the motor near the rotating shaft. A sliding groove is fixedly connected to the side of the rotating shaft near the connecting post, and the rotating shaft is engaged with the output end of the motor through the connecting post and the sliding groove.

[0020] The advantage of adopting the above-mentioned further solution is that it facilitates the removal and replacement of the shaft without affecting its rotation.

[0021] In a preferred embodiment, a fixed base is fixedly connected to the side of the feed inlet away from the motor, and a second slider is fixedly connected to the side of the rotating shaft near the fixed base. A bearing is slidably connected to the second slider, and the bearing is threadedly connected to the fixed base.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the bearing is fixed on the motor by pushing the shaft to engage with the connecting column, thereby improving the stability of the shaft during rotation.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. By setting up a feeding assembly, the main rotating component and the auxiliary rotating component work together with the blades to cut and crush the feed material. This process results in smaller and more uniform particle size, effectively preventing inlet blockage caused by excessively large particles, high viscosity, or excessively long fibers. This helps ensure smooth material flow and maintains the normal operation of the fermenter.

[0025] 2. By setting up a transmission assembly and installing a connecting column on the support plate, the driven wheel is mounted on the connecting column and can rotate. When the shaft rotates, it drives the driven wheel to rotate in the opposite direction through the driving wheel. The driven wheel is driven to rotate in the same direction through the rack, so that the main rotating part and the auxiliary rotating part drive the rotating blade to move in opposite directions. In this way, the material can be cut from multiple angles. Regardless of its shape, size and texture, it is easier to be captured by the cutter rotating in different directions, so that the cutting is more thorough and detailed, avoiding cutting dead corners and material residue, which is conducive to improving the fermentation efficiency of the material.

[0035] 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. Example

[0036] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a modular high-efficiency dry anaerobic digester, including: a digester body 1, which is composed of a stirring system, a feeding and discharging system, and a gas collection system. The stirring system is used to stir the materials in the digester body to make the materials mix evenly. The feeding and discharging system is used to send organic matter into the digester body 1 and discharge the reacted materials. The gas collection system purifies the collected biogas for better utilization.

[0037] like Figure 1 - Figure 3 As shown: Feeding assembly 2, which is placed on the top of fermentation tank body 1. Feeding assembly 2 includes a feed inlet 21 fixed on the top of fermentation tank body 1 and a support plate 22 fixed inside the feed inlet 21. A blade body 25 is fixedly connected to the top of the support plate 22. A main rotating component 23 is provided on the support plate 22. A secondary rotating component 24 is provided on the side of the support plate 22 near the main rotating component 23. Rotating blades 26 are fixedly connected to the side of the main rotating component 23 and the secondary rotating component 24 near the support plate 22.

[0038] like Figure 3As shown: Transmission assembly 3, located inside the feeding assembly 2, drives the main rotating component 23 and the auxiliary rotating component 24 to rotate in different directions. Transmission assembly 3 includes a rotating shaft 32 located inside the support plate 22 and a drive wheel 33 fixedly connected to the rotating shaft 32 near one end of the auxiliary rotating component 24. A rack 35 is provided on the side of the auxiliary rotating component 24 near the drive wheel 33. A driven wheel 34 meshes between the drive wheel 33 and the rack 35. The auxiliary rotating component 24 is connected to the drive wheel 33 via the rack 35 and the driven wheel 34. By rotating the main rotating component 23 and the auxiliary rotating component 24, the cutter body 25 and the rotating blade 26 cooperate to cut and crush the fed material, resulting in smaller and more uniform particle size. This effectively avoids damage to the feed inlet 21 caused by excessively large particles, high viscosity, or excessively long fibers. The blockage problem is solved, which helps to ensure smooth material flow and maintain the normal operation of the fermentation tank. By installing the connecting column 7 on the support plate 22, the driven wheel 34 is installed on the connecting column 7 and can rotate on it. When the rotating shaft 32 rotates, the rotating shaft 32 drives the driven wheel 34 to rotate in the opposite direction through the driving wheel 33. The driven wheel 34 is driven to rotate in the same direction as the driven wheel 34 through the rack 35. This causes the main rotating part 23 and the auxiliary rotating part 24 to drive the rotating blade 26 to move in opposite directions, which can cut the material from multiple angles. When the material enters the feed port 21, regardless of its shape, size and texture, it is easier to be captured by the cutter rotating in different directions, so that the cutting is more thorough and detailed, avoiding cutting dead corners and material residue, which helps to improve the fermentation efficiency of the material.

[0039] Furthermore, such as Figure 3 As shown: A slider 27 is fixedly connected to the side of the auxiliary rotating component 24 and the main rotating component 23 near the support plate 22. The main rotating component 23 and the auxiliary rotating component 24 are slidably connected to the support plate 22 through the slider 27. By installing slider 27 on both the main rotating component 23 and the auxiliary rotating component 24, and then placing the slider 27 inside the support plate 22, when the main rotating component 23 and the auxiliary rotating component 24 drive the slider 27 to rotate, the cooperation structure between the slider 27 and the support plate 22 can effectively ensure the stability of the slider 27 during the rotation process.

[0040] Furthermore, such as Figure 3 As shown: Bearings 4 are fixedly connected to one end of the rotating shaft 32 near the feed port 21 and the support plate 22. The rotating shaft 32 is rotatably connected to the feed port 21 and the support plate 22 through the bearings 4. By using the bearings 4 to precisely install the rotating shaft 32 between the feed port 21 and the support plate 22, the smooth and unobstructed rotation of the rotating shaft 32 is effectively ensured. At the same time, the driven wheel 34 is specially provided with a slot that perfectly matches the snap-fit ​​block 37. This design greatly facilitates the separation operation between the rotating shaft 32 and the bearings 4.

[0041] Furthermore, such as Figure 3 As shown: A snap-fit ​​block 37 is fixedly connected to the rotating shaft 32. The rotating shaft 32 is snapped with the drive wheel 33 and the main rotating component 23 through the snap-fit ​​block 37. By opening grooves on the drive wheel 33 and the main rotating component 23 that match the rotating shaft 32, it is easy for the rotating shaft 32 to drive the drive wheel 33 and the main rotating component 23 to rotate. When the rotating shaft 32 is taken out from the inside of the support plate 22, it is also easy to separate the rotating shaft 32 from the drive wheel 33 and the main rotating component 23.

[0042] Furthermore, such as Figure 3 As shown: A connecting piece 36 is fixedly connected between the drive wheel 33 and the bearing 4. The bearing 4 and the drive wheel 33 are tightly connected into one unit through the connecting piece 36. In this way, when the drive wheel 33 rotates, it can obtain more reliable support and fixation under the action of the connecting piece 36, thereby effectively improving its stability during rotation and reducing unnecessary shaking and deviation.

[0043] The above solutions also have the problem that the rotating shaft 32 wears out severely after prolonged use and needs to be replaced. Figure 4 As shown: A motor 31 is fixedly connected to one side of the feed inlet 21. A connecting post 7 is provided on the side of the output end of the motor 31 near the rotating shaft 32. A sliding groove 8 is fixedly connected on the side of the rotating shaft 32 near the connecting post 7. The rotating shaft 32 is engaged with the output end of the motor 31 through the connecting post 7 and the sliding groove 8. When the rotating shaft 32 is installed inside the support plate 22 of the feed inlet 21, the rotating shaft 32 drives the sliding groove 8 to engage inside the connecting post 7. When the motor 31 starts, the output end of the motor 31 drives the rotating shaft 32 to rotate through the cooperation of the connecting post 7 and the sliding groove 8. This allows the rotating shaft 32 to be easily removed and replaced without affecting its rotation. The bearing 4, the drive wheel 33, and the auxiliary rotating part 24 are all provided with slots that match the connecting post 7, making it easy to remove the connecting post 7.

[0044] Furthermore, such as Figure 4 As shown: A fixed seat 5 is fixedly connected to the side of the feed inlet 21 away from the motor 31. A slider 6 is fixedly connected to the side of the rotating shaft 32 near the fixed seat 5. A bearing 4 is slidably connected to the slider 6. The bearing 4 is threadedly connected to the fixed seat 5. Through the rotating shaft 32, the bearing 4 moves towards the motor 31 through the thread line inside the fixed seat 5. The bearing 4 pushes the rotating shaft 32 to engage with the connecting post 7 on the motor 31, thereby fixing the rotating shaft 32 and improving the stability of the rotating shaft 32 during rotation.

[0045] Working principle: such as Figure 1 - Figure 4As shown, the feeding and discharging system on the fermentation tank body 1 is first started to allow the material to enter the interior of the feed inlet 21. At this time, the motor 31 is started. The motor 31 drives the rotating shaft 32 to rotate through the connecting column 7 and the slide 8. The transmission component 3 then drives the main rotating component 23 and the driving wheel 33 to rotate through the snap-fit ​​block 37. When the driving wheel 33 rotates, it drives the driven wheel 34 to rotate in the opposite direction. The driven wheel 34 is driven to rotate in the same direction as the driven wheel 34 through the rack 35. This causes the main rotating component 23 and the auxiliary rotating component 24 to drive the rotating blade 26 to move in opposite directions, so that the blade body 25 and the rotating blade 26 cooperate to move from multiple angles. The material is cut so that when it enters the feed inlet 21, regardless of its shape, size, or texture, it is more easily captured by the cutting blades rotating in different directions, thus making the cutting more thorough and precise, avoiding cutting dead corners and material residue, which is conducive to improving the fermentation efficiency of the material. After the feeding component 2 and the transmission component 3 have been used for a long time, the rotating shaft 32 will wear out. At this time, the rotating shaft 32 needs to be replaced. The rotating shaft 32 is rotated, and the bearing 4 is taken out from the inside of the fixed seat 5. The bearing 4 drives the rotating shaft 32 to move through the slider 6, so that the rotating shaft 32, the connecting column 7 and the motor 31 are separated, and then the rotating shaft 32 can be taken out for replacement.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
