Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment devices, and in particular to a stirring mechanism, a stirring system and a kitchen waste fermentation device. Background Technology

[0002] The stirring mechanism inside the fermentation device plays a crucial role in ensuring that the materials and biological inoculum are thoroughly mixed, while also promoting uniform heating, humidification, and full contact with oxygen, thereby guaranteeing the full fermentation of kitchen waste.

[0003] However, existing mixing shafts used in food waste fermentation chambers have revealed several problems in practical applications that urgently need to be addressed. Firstly, the chambers themselves are typically large, resulting in long mixing shafts. Traditional packing seals are ineffective in this situation. Due to the high moisture content of the material entering the fermentation chamber, the seals at both ends of the mixing shaft are prone to wear and leakage after a period of operation, severely impacting the normal operation of the equipment and environmental hygiene. Secondly, the excessive length of the mixing shaft not only significantly increases material purchase costs but also keeps subsequent processing costs high. For example, a fermentation chamber with a daily processing capacity of 5 tons has a mixing shaft length of 4982 mm, which undoubtedly greatly increases production costs. Thirdly, after equipment installation, the excessive length of the mixing shaft makes subsequent disassembly and maintenance extremely difficult, requiring significant manpower, resources, and time. Fourthly, if the mixing shaft relies solely on the flange for load-bearing, the weld seams are prone to cracking due to excessive stress during long-term operation, thus affecting the service life of the mixing shaft and the stability of the equipment.

[0004] In summary, the existing mixing shafts used in food waste fermentation chambers have significant shortcomings in terms of sealing performance, cost control, ease of maintenance, and structural stability. Utility Model Content

[0005] The purpose of this invention is to provide a stirring mechanism, a stirring system, and a food waste fermentation device to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A stirring mechanism includes a central standard section, a left half-shaft, a right half-shaft, and connecting components. The left half-shaft, central standard section, and right half-shaft are connected sequentially. The connecting components and flanges are provided at both ends of the central standard section, at one end of the left half-shaft connected to the central standard section, and at one end of the right half-shaft connected to the central standard section. The connecting components include pins and connecting blocks. The connecting blocks are inserted into and welded to the corresponding left half-shaft, central standard section, or right half-shaft. The pins pass through the corresponding connecting blocks and the left half-shaft, central standard section, or right half-shaft to connect the corresponding connecting blocks and the left half-shaft, central standard section, or right half-shaft. Connected connecting blocks are welded together, and adjacent flanges are welded together.

[0008] In a preferred embodiment, the pin is welded to the corresponding connecting block and the left half-shaft, intermediate standard section, or right half-shaft.

[0009] In a preferred embodiment, the intermediate standard section has two or more sections.

[0010] In a preferred embodiment, two adjacent flanges are provided with a raised or recessed structure.

[0011] In a preferred embodiment, the connecting member includes two or more of the pins.

[0012] A stirring system includes the stirring mechanism, and further includes multiple blades, a drive gear, a sealing component, and a bearing housing, which are distributed and installed on the intermediate standard section, the left half shaft, and the right half shaft. The sealing component and the bearing housing are respectively provided on the left half shaft and the right half shaft, and the drive gear is connected to the left half shaft or the right half shaft.

[0013] In a preferred embodiment, the sealing member includes a sealing seat, an O-ring, an air inlet pipe, a sealing skeleton, and a sealing end cap, wherein a sealing cavity is formed between the sealing seat, the O-ring, the sealing skeleton, and the sealing end cap, and the air inlet pipe is connected to the sealing cavity.

[0014] In a preferred embodiment, a dustproof ring is further included, which is disposed on the sealing seat.

[0015] In a preferred embodiment, an end face pressure plate is further included, which is disposed corresponding to the sealing end cap.

[0016] A food waste fermentation device includes the stirring mechanism, or includes the stirring system.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In terms of structural design, the multi-segment stirring shaft uses the middle section as a standard section, breaking the limitations of traditional long shafts. This design makes the equipment more flexible in terms of length expansion, allowing for easy addition or reduction of the number of standard sections according to the needs of different specifications of food waste fermentation chambers, thus achieving standardized product design and production. This not only significantly reduces the complexity of the manufacturing process but also improves production efficiency, while reducing material and processing costs, effectively solving the problem of high processing costs associated with traditional long stirring shafts.

[0019] In terms of connection structure, a composite connection method combining pins, connecting blocks, and flanges is adopted, which greatly enhances the overall stability and reliability of the agitator shaft. The connecting block is inserted into the half-shaft or standard section and welded, and then fixed a second time by pins. The pins are also welded to the shaft body, forming a stable three-dimensional connection structure that disperses the torque force and avoids the risk of cracking due to excessive stress on the flange weld. The concave-convex fit and welding of the connecting block and the flange further enhances the tightness and torsional resistance of the connection, effectively improving the working stability of the agitator shaft under high torque conditions. The welding of the flange to the shaft body further strengthens the overall structural strength, ensuring the reliability of the agitator shaft during long-term operation.

[0020] In addition, the multi-section structure makes the agitator shaft easier to disassemble and maintain. Compared with the traditional extra-long agitator shaft, each section can be disassembled independently, which significantly reduces the difficulty of maintenance, shortens the maintenance time, and reduces the maintenance cost.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example

[0029] Reference Figure 1 , Figure 4 and Figure 5 A stirring mechanism includes a central standard section 1, a left half-shaft 2, a right half-shaft 3, and connecting components. The left half-shaft 2, the central standard section 1, and the right half-shaft 3 are connected sequentially. The connecting components and flanges are provided at both ends of the central standard section 1, at one end of the left half-shaft 2 connected to the central standard section 1, and at one end of the right half-shaft 3 connected to the central standard section 1. The connecting components include pins 4 and connecting blocks 5. The connecting blocks 5 are inserted into the corresponding left half-shaft 2, central standard section 1, or right half-shaft 3 and welded to the corresponding left half-shaft 2, central standard section 1, or right half-shaft 3. The pins 4 pass through the corresponding connecting blocks 5 and the corresponding left half-shaft 2, central standard section 1, or right half-shaft 3 to connect the corresponding connecting blocks 5 and the corresponding left half-shaft 2, central standard section 1, or right half-shaft 3. The connected connecting blocks 5 are welded together, and the adjacent flanges are welded together.

[0030] In this embodiment, the mixing mechanism features a multi-segment mixing shaft with a standard middle section, breaking the limitations of traditional long shafts. This design allows for greater flexibility in length expansion, enabling the number of standard sections to be easily increased or decreased according to the needs of different specifications of food waste fermentation chambers, thus achieving standardized product design and production. This not only significantly reduces the complexity of the manufacturing process but also improves production efficiency, while simultaneously reducing material and processing costs, effectively solving the problem of high processing costs associated with traditional long mixing shafts.

[0031] In terms of connection structure, a composite connection method combining pin 4, connecting block 5, and flange is adopted, which greatly enhances the overall stability and reliability of the stirring shaft. The connecting block 5 is inserted into the half shaft or standard section and welded, and then fixed again by pin 4; the welding of the flange to the shaft body further strengthens the overall structural strength and ensures the reliability of the stirring shaft during long-term operation.

[0032] In addition, the multi-section structure makes the agitator shaft easier to disassemble and maintain. Compared with the traditional extra-long agitator shaft, each section can be disassembled independently, which significantly reduces the difficulty of maintenance, shortens the maintenance time, and reduces the maintenance cost.

[0033] To further enhance the stability of the structure, the pin 4 is welded to the corresponding connecting block 5 and the left half-shaft 2, the middle standard section 1 or the right half-shaft 3 to form a stable three-dimensional connection structure, which disperses the torque force and avoids the risk of the flange weld cracking due to excessive stress.

[0034] In this embodiment, the intermediate standard section 1 is set to one. The specific number of intermediate standard sections 1 can be selected according to actual needs, and can be set to one, two, three, or even more, depending on the actual working conditions.

[0035] Furthermore, the two adjacent flanges are provided with a concave-convex structure, which further enhances the tightness and torsional resistance of the connection, and effectively improves the working stability of the stirring shaft under high torque conditions.

[0036] To further enhance structural stability, the connecting component includes two or more of the pins 4. Example

[0037] Reference Figures 1 to 3 A stirring system includes the stirring mechanism described in Embodiment 1, and further includes multiple blades 6, a drive gear 7, a sealing component 8, and a bearing seat 17, which are distributed and installed on the intermediate standard section 1, the left half-shaft 2, and the right half-shaft 3. The sealing component 8 and the bearing seat 17 are respectively provided on the left half-shaft 2 and the right half-shaft 3. The drive gear 7 is connected to the left half-shaft 2 or the right half-shaft 3. The sealing component 8 improves the sealing performance of the stirring system.

[0038] The sealing component 8 includes a sealing seat 9, an O-ring 10, an air inlet pipe 11, a sealing skeleton 12, and a sealing end cap 13. A sealing cavity 14 is formed between the sealing seat 9, O-ring 10, sealing skeleton 12, and sealing end cap 13, and the air inlet pipe 11 connects to the sealing cavity 14. This stirring system rationally distributes multiple blades 6, drive gears 7, sealing components 8, and bearing seats 17 on various shaft sections of the stirring mechanism, forming a fully functional and highly efficient working system. The connection design between the drive gear 7 and the half-shaft ensures stable power transmission, providing sufficient power for the stirring operation; the blades 6 are evenly distributed on the shaft, effectively improving the uniformity and thoroughness of material stirring, promoting efficient fermentation of kitchen waste in the fermentation chamber.

[0039] Regarding improved sealing performance, the sealing seat 9, O-ring, sealing skeleton 12, and sealing end cap 13 together form a closed sealing cavity 14, which is connected to external high-pressure gas through the air inlet pipe 11. When high-pressure gas is injected into the sealing cavity 14, it forms a gas chamber with stable pressure. This pressure can precisely act on the lip of the sealing skeleton 12, making it tightly fit the surface of the stirring shaft. Compared with traditional packing seals, this dynamic sealing mechanism can effectively resist the erosion of materials with high moisture content. Even after the equipment has been running for a long time, it can maintain a good sealing effect, eliminating material leakage problems at the source. This not only avoids environmental pollution caused by material leakage from the fermentation chamber, but also ensures the continuity and stability of the fermentation process and reduces the number of equipment downtime maintenance caused by material leakage.

[0040] The stirring system in this embodiment also includes a dustproof ring 15, which is disposed on the sealing seat 9. It effectively prevents external dust, impurities, and other particulate matter from entering the sealing cavity 14, avoiding wear and contamination of the sealing components 8 such as O-rings and sealing skeletons 12.

[0041] The stirring system of this embodiment also includes an end face pressure plate 16, which is disposed corresponding to the sealing end cap 13. The end face pressure plate 16 can form a stable clamping force on the sealing end cap 13, ensuring that the sealing end cap 13 fits tightly with other sealing components, preventing loosening or displacement of the sealing cavity 14, thereby ensuring the integrity of the sealing structure.
