Description

Technical Field

[0001] This utility model relates to the technical field of food waste treatment, and in particular to a stirring structure applied to food waste treatment equipment. Background Technology

[0002] In modern food waste processing equipment, the mixing structure is one of the core components. Its main function is to ensure the uniform mixing and full fermentation of food waste materials. The design of the mixing structure directly affects the food waste processing efficiency and the service life of the equipment. However, the first secondary shaft design with spiral integral blades commonly used in existing food waste processing equipment has some significant technical defects. These problems have gradually become apparent in practical applications, affecting the performance and reliability of the equipment.

[0003] Existing mixing structures typically employ spiral-shaped integral blades. While this design can effectively propel and mix kitchen waste, the large contact area between the blades and the material, coupled with the material's high viscosity and density, significantly increases the torque and load on the first bearing.

[0004] Because the first bearing is subjected to a large load, it is prone to fatigue damage under long-term operation, which can lead to shaft deformation or breakage, thereby reducing the service life of the equipment. In addition, frequent maintenance and replacement of the first bearing also increases operating costs.

[0005] To overcome larger loads, the stirring structure requires more energy, which not only increases operating costs but also negatively impacts energy efficiency.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] The existing stirring structures mentioned above typically use spiral integral blades, which cause a significant increase in the torque and load on the first bearing due to the large contact area between the blades and the material.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A stirring structure for use in a food waste processing device includes: a stirring shaft assembly and a third drive assembly. The third drive assembly is driven to drive the stirring shaft assembly to rotate. The stirring shaft assembly includes a main shaft driven to drive the third drive assembly and a plurality of first auxiliary shafts spirally distributed along the main shaft.

[0010] As described above, a stirring structure for a food waste processing device includes a first auxiliary shaft comprising a shaft body and a blade disposed at one end of the shaft body, the other end of the shaft body being connected to the main shaft, and the blade having a certain curvature.

[0011] As described above, in a stirring structure applied to a food waste processing device, the blades are shaped like shovels.

[0012] As described above, in a stirring structure applied to a food waste processing equipment, the other end of the shaft is either integrally formed with the main shaft or detachably connected.

[0013] As described above, in a stirring structure for a food waste processing device, the main shaft is further provided with two opposing secondary shafts located at both ends of the main shaft.

[0014] In the stirring structure described above for use in a food waste processing device, the second secondary shaft is T-shaped.

[0015] As described above, in a stirring structure applied to a food waste processing equipment, the second auxiliary shaft and the main shaft are either integrally formed or detachably connected.

[0016] As described above, a stirring structure for a food waste treatment device further includes a fermentation tank. The fermentation tank has a fermentation chamber, a main discharge port and a collection component on one side. The material in the fermentation tank can be conveyed and guided to the main discharge port by the stirring shaft assembly and collected by the collection component.

[0017] As described above, a stirring structure for a food waste treatment device includes a fermentation tank with a second door component.

[0018] As described above, a stirring structure for a food waste treatment device includes a collection box located on one side of a fermentation tank, the top of which has an opening, and the main discharge port located above the collection box.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a stirring structure for a food waste processing equipment, comprising a stirring shaft assembly and a third drive assembly. The stirring shaft assembly includes a main shaft, which is connected to the third drive assembly and is the main rotating component of the stirring shaft assembly. The stirring shaft assembly also includes multiple first auxiliary shafts, which are spirally distributed along the shaft of the main shaft.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown in the figure, a stirring structure for a kitchen waste treatment device in this embodiment includes a fermentation tank 22, in which a fermentation chamber 21 is provided. The stirring structure includes a stirring shaft assembly 24 and a third drive assembly 25. The third drive assembly 25 is driven to drive the stirring shaft assembly 24 to rotate. The stirring shaft assembly 24 includes a main shaft 241 driven to drive the third drive assembly 25 and a plurality of first auxiliary shafts 242 spirally distributed along the shaft of the main shaft 241.

[0029] Specifically, the stirring structure in this embodiment includes a stirring shaft assembly 24 and a third drive assembly 25. The stirring shaft assembly includes a main shaft, which is connected to the third drive assembly and is the main rotating component of the stirring shaft assembly. The stirring shaft assembly also includes multiple first auxiliary shafts, which are spirally distributed along the shaft of the main shaft. The design of the first auxiliary shafts increases the contact area and stirring effect, making the stirring more uniform and efficient. Furthermore, the spaced arrangement of the first auxiliary shafts reduces the pressure of mixing on the first auxiliary shafts. Compared with the existing design of first auxiliary shafts with spiral integral blades, the design of multiple spaced first auxiliary shafts can effectively reduce the load of mixing on the first auxiliary shafts without affecting the conveying and stirring functions of the stirring structure, and extend the service life of the first auxiliary shafts.

[0030] Specifically, the stirring structure includes a stirring shaft assembly and a third drive assembly. The third drive assembly is connected to the stirring shaft assembly in a transmission manner, providing power to drive the stirring shaft assembly to rotate.

[0031] Specifically, the third drive component is activated, driving the main shaft to rotate via a transmission connection. The rotation of the main shaft drives the entire stirring shaft assembly to rotate. As the main shaft rotates, the first auxiliary shaft, which is spirally distributed along the main shaft, also rotates. The design of the first auxiliary shaft enables the stirring blades or stirring arms to more effectively stir kitchen waste and / or microbial mixtures, promoting uniform mixing and full contact.

[0032] Specifically, through the synergistic effect of the main shaft and the first auxiliary shaft, the stirring shaft assembly can more effectively stir the substances in the fermentation chamber, thereby improving stirring efficiency and fermentation effect.

[0033] Preferably, the design of the stirring shaft assembly is easy to disassemble and maintain, and the first auxiliary shaft can be inspected and replaced regularly to ensure stirring effect and equipment life.

[0034] During fermentation, the third drive component is activated, driving the stirring shaft assembly to rotate via a transmission connection. This stirs the microbial mixture and kitchen waste in the fermentation chamber. The function of the stirring structure is to ensure that the microbial mixture and kitchen waste are evenly mixed in the fermentation chamber, ensuring that the microorganisms and kitchen waste are in full contact, thus promoting the fermentation reaction.

[0035] The stirring structure can effectively promote the uniform mixing of microbial mixtures and kitchen waste, improve the material transfer efficiency during fermentation, thereby accelerating the fermentation process. Stirring can also prevent the microbial mixtures and kitchen waste from settling in the fermentation chamber, maintain the uniform distribution of substances in the fermentation chamber, and avoid local over-concentration or over-diluteness.

[0036] Preferably, when no kitchen waste has been added, but microorganisms and various mixtures have been added, the stirring structure starts a stirring cycle mode. First, it stirs in the forward direction for a period of time, such as three to five minutes, then pauses stirring for 15 to 30 seconds, then stirs in the reverse direction for a period of time, such as three to five minutes, then pauses stirring for 15 to 30 seconds, then stirs in the forward direction for a period of time, such as three to five minutes, and finally stops stirring for 20 to 25 minutes. This process is one cycle of the stirring cycle. In this way, microorganisms and various mixtures can be better mixed to form microbial mixtures. During the stirring process, moisture in the microbial mixtures can be effectively discharged to ensure the activity of microorganisms.

[0037] Preferably, this forward and reverse stirring method can avoid excessive accumulation of microbial mixture at one end of the fermentation tank, ensuring that the microbial mixture can be mixed evenly and distributed evenly in the fermentation tank.

[0038] Preferably, after the microorganisms and mixed materials have been placed in the fermentation tank for a period of time, approximately 24 hours later,

[0039] Kitchen waste can be put into the kitchen waste treatment equipment. After the kitchen waste has undergone the oil-water separation process, it enters the fermentation tank. The stirring method is similar to the stirring and circulation mode mentioned above. This forward and reverse stirring method can avoid excessive microbial mixing and the accumulation of kitchen waste at one end of the fermentation tank. It ensures that the microbial mixture and kitchen waste can be mixed evenly, thereby improving the degradation effect of microorganisms.

[0040] Preferably, the stirring structure stops stirring to provide sufficient time for microorganisms to mix and degrade food waste. Furthermore, this stirring cycle mode can timely stir the food waste and microorganisms to release moisture and ensure that the environment in which the microorganisms are located is always within a suitable humidity range.

[0041] like Figures 1 to 5 As shown, the first secondary shaft 242 of this embodiment includes a shaft body 2421 and a blade 2422 disposed on one end of the shaft body 2421. The other end of the shaft body is connected to the main shaft 241, and the blade body of the blade 2422 has a certain curvature.

[0042] The first secondary shaft includes a shaft body and a blade located at one end of the shaft body. The blade is used to stir the material in the fermentation chamber. The blade is usually designed to maximize the stirring effect, and its body has a certain curvature, which helps to provide greater stirring force and better hydrodynamic characteristics.

[0043] Preferably, the other end of the shaft is connected to the main shaft. This connection can be welding, threaded connection or other types of mechanical connection to ensure that the first secondary shaft is stable during the stirring process and can withstand the force caused by stirring. Through the blades on the first secondary shaft, the material in the fermentation chamber can be stirred more effectively, thereby accelerating the fermentation process. The arc-shaped blades are usually more efficient and can provide a strong stirring effect while consuming less energy.

[0044] like Figures 1 to 5 As shown, the blade 2422 in this embodiment is shovel-shaped, similar to a shovel in gardening tools, with a wide shovel surface and a certain curvature. This design helps to better push and turn the material during the mixing process, similar to the action of a shovel digging in the soil, thereby promoting the circulation and mixing of the material in the fermentation chamber. The wide shovel surface and curvature design of the blade enable it to turn the material, turning the material at the bottom to the surface, or pushing the material on the surface to the bottom, so as to achieve uniform distribution and full contact of the material.

[0045] Preferably, the other end of the shaft body is integrally formed with the main shaft 241 or is a detachable connection structure, and a suitable design can be selected according to actual needs.

[0046] like Figures 1 to 5 As shown, in this embodiment, the main shaft 241 is also provided with two opposing second auxiliary shafts 243. The two second auxiliary shafts 243 are located at both ends of the main shaft 241 and close to the inner wall of the fermentation chamber 21. This arrangement helps to directly act on the edge area of ​​the fermentation chamber, which is usually a dead corner for stirring and is prone to material accumulation.

[0047] like Figures 1 to 5 As shown, the second auxiliary shaft 243 in this embodiment is T-shaped. The T-shaped second auxiliary shaft 243 has a large stirring range. The T-shaped second auxiliary shaft 243 can stir and transport kitchen waste and / or humic fertilizer in the dead corners at both ends of the fermentation tank, avoiding the accumulation of kitchen waste and / or humic fertilizer at both ends of the fermentation tank.

[0048] Preferably, the second auxiliary shaft 243 and the main shaft 241 are integrally formed or detachably connected, and the appropriate design can be selected according to actual needs.

[0049] Because a large amount of material usually accumulates at the corners of the inner walls at both ends of the fermentation chamber, the auxiliary shaft with a certain curvature of the paddle body usually cannot stir the material at this location. In fact, due to the weight of the material, the paddle blades 2422 on the auxiliary shaft may be damaged. Or, for the design where the auxiliary shaft is detachably connected to the main shaft, the auxiliary shaft is more easily affected by the weight of the material on the main shaft, which may cause the auxiliary shaft to shift position or fall off the main shaft, affecting the normal operation of the auxiliary shaft.

[0050] Preferably, the T-shaped subshaft is subjected to more uniform force, reducing stress concentration caused by single-point force, thereby reducing the risk of subshaft damage and making it less prone to damage. With the design of the second subshaft 243 being detachably connected to the main shaft, the subshaft is not easily affected by the weight of the material on the main shaft, and is less likely to be displaced or fall off the main shaft, ensuring the normal operation of the subshaft.

[0051] like Figures 1 to 5 As shown, the fermentation tank 22 in this embodiment is provided with a main discharge port 26 and a collection component 27 on one side. The material in the fermentation tank 22 can be conveyed and guided to the main discharge port 26 by the stirring shaft assembly 24 and discharged, and collected by the collection component 27.

[0052] Preferably, with the cooperation of the stirring shaft assembly 24 and the third drive assembly 25, the material in the fermentation tank can be conveyed and guided to the main discharge port. The material is discharged from the fermentation tank through the main discharge port and enters the collection assembly. The collection assembly collects the material discharged from the main discharge port for subsequent processing or use.

[0053] Specifically, the stirring shaft assembly 24 effectively transports the material to the main discharge port, ensuring rapid and smooth discharge of the fermented material, and the uniform stirring and discharge process ensures the stability of the fermentation quality.

[0054] Specifically, by adopting the design of the main shaft 241 and multiple first auxiliary shafts 242 spirally distributed along the main shaft 241, the mixing structure can simultaneously perform the functions of mixing and conveying, making the structure of the food waste processing equipment more compact and eliminating the need for additional conveying structures.

[0055] Specifically, the design of the main discharge port and collection components allows the material to be easily collected, simplifying subsequent processing procedures. The convenient collection method reduces manual intervention and improves management convenience and efficiency.

[0056] like Figures 1 to 5 As shown, the fermentation tank 22 in this embodiment is provided with a second door component, which includes a second door 28 and a fourth drive component 29. The fourth drive component 29 can drive the second door 28 to block or move away from the main discharge port 26.

[0057] Specifically, the second door component controls the opening and closing of the second door through the fourth drive assembly.

[0058] When it is necessary to discharge the material, the fourth drive assembly drives the second box door away from the main discharge port, so that the main discharge port opens and the material can be discharged.

[0059] When material discharge is not required, the fourth drive component drives the second box door to block the main discharge port, preventing material from being discharged.

[0060] When fermentation is complete or when some material needs to be discharged, the control system activates the fourth drive component. The fourth drive component drives the second chamber door to open the main discharge port, and the material is discharged through the main discharge port. After discharge, the fourth drive component drives the second chamber door to close the main discharge port to ensure the system is sealed.

[0061] Preferably, the fourth drive component can accurately control the opening and closing of the second box door to ensure effective sealing or opening of the main discharge port. Combined with the control system, the opening and closing operation of the second box door can be automated, reducing manual intervention.

[0062] like Figures 1 to 5 As shown, the collection component 27 of this embodiment includes a collection box located on one side of the fermentation box 22. The top of the collection box 271 has an opening, and the main discharge port 26 is located above the collection box 271.

[0063] Specifically, the material is discharged from the fermentation tank through the main discharge port, which is located above the collection box. The discharged material enters the collection box through the opening at the top of the collection box and is effectively collected by the collection component. The design of the opening at the top of the collection box simplifies the discharge and collection process and reduces complex mechanisms. Users only need to remove the collection box 271 after collecting the kitchen waste to complete the collection. It has the advantages of simple structure and convenient operation.

[0064] like Figures 1 to 5 As shown, the collection component 27 in this embodiment also includes a guide plate 272 disposed on one side of the fermentation tank 22. The guide plate 272 has a certain slope and can guide the material discharged from the main discharge port 26 to the collection box 271. With this design, the kitchen waste can fall accurately from the main discharge port 26 into the collection box 271, ensuring that the kitchen waste is not scattered, maintaining the cleanliness of the working environment, and ensuring the accurate collection of kitchen waste.

[0065] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
