Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and in particular to a stirring structure applied to kitchen waste treatment equipment. Background Art

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

[0003] Existing mixing structures usually use spiral integral blades. Although this design can effectively push and mix kitchen waste materials, the large contact area between the blades and the materials, as well as the high viscosity and density of the materials, causes a significant increase in the torque and load on the first auxiliary shaft.

[0004] Since the first auxiliary shaft is subjected to a large load, fatigue damage is likely to occur during long-term operation, causing deformation or breakage of the shaft, thereby reducing the service life of the equipment. In addition, frequent maintenance and replacement of the first auxiliary shaft also increases operating costs.

[0005] In order to overcome the larger load, the mixing structure needs to consume more energy, which not only increases the operating costs but also has a negative impact on energy efficiency.

[0006] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0007] In view of the technical problem that the existing stirring structure mentioned above usually adopts a spiral integral blade, the large contact area between the blade and the material leads to a significant increase in the torque and load on the first auxiliary shaft.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a stirring structure applied to a kitchen waste processing device in this embodiment includes a fermentation box 22, in which a fermentation chamber 21 is arranged, wherein the stirring structure includes a control component, a stirring shaft component 24 and a third driving component 25, wherein the third driving component 25 is transmission-connected to the stirring shaft component 24, the control component is electrically connected to the third driving component 25, and can enable the third driving component 25 to drive the stirring shaft component 24 to rotate forward or reversely, and the stirring shaft component 24 includes a main shaft 241 transmission-connected to the third driving component 25 and a plurality of first secondary shafts 242 spirally distributed along the shaft body of the main shaft 241.

[0023] Specifically, the stirring structure of this embodiment includes a stirring shaft assembly 24 and a third drive assembly 25. The stirring shaft assembly includes a main shaft, which is transmission-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 sub-shafts, which are spirally distributed along the shaft body of the main shaft. The design of the first sub-shaft increases the contact area and stirring effect of stirring, making the stirring more uniform and efficient. Moreover, the first sub-shaft adopts this interval arrangement method to reduce the pressure of the mixture on the first sub-shaft. Compared with the existing design of the first sub-shaft with spiral integral blades, the design of multiple interval-arranged first sub-shafts can effectively reduce the load of the mixture on the first sub-shaft without affecting the conveying and stirring functions of the stirring structure, thereby extending the service life of the first sub-shaft.

[0024] Specifically, the stirring structure includes a stirring shaft assembly and a third driving assembly. The third driving assembly is transmission-connected to the stirring shaft assembly to provide power to drive the stirring shaft assembly to rotate, and the control assembly can control the third driving assembly to drive the stirring shaft assembly 24 to rotate forward or reverse.

[0025] When the third driving assembly is started, the main shaft is driven to rotate through the transmission connection. The rotation of the main shaft drives the entire stirring shaft assembly to rotate. As the main shaft rotates, the first secondary shaft distributed spirally along the main shaft also rotates. The design of the first secondary shaft enables the stirring blades or stirring arms to stir the kitchen waste and / or microbial mixture more effectively, promoting uniform mixing and sufficient contact.

[0026] Specifically, through the synergistic effect of the main shaft and the first secondary shaft, the stirring shaft assembly can more effectively stir the substances in the fermentation chamber, thereby improving the stirring efficiency and the fermentation effect.

[0027] Preferably, the design of the stirring shaft assembly is convenient for disassembly and maintenance, and the first secondary shaft can be regularly inspected and replaced to ensure stirring effect and equipment life.

[0028] During the fermentation process, the third drive component is started and drives the stirring shaft component to rotate forward or reversely through the transmission connection to stir the microbial mixture and kitchen waste in the fermentation chamber. The function of the stirring structure is to evenly mix the microbial mixture and kitchen waste in the fermentation chamber, ensure sufficient contact between the microorganisms and the kitchen waste, and promote the fermentation reaction.

[0029] The stirring structure can effectively promote the uniform mixing of the microbial mixture and kitchen waste, improve the material transfer efficiency during the fermentation process, and thus accelerate the fermentation process. Stirring can also prevent the microbial mixture and kitchen waste from settling in the fermentation chamber, maintain a uniform distribution of materials in the fermentation chamber, and avoid local over-concentration or over-dilutement.

[0030] Preferably, when no kitchen waste has been added and microorganisms and various mixed materials have been added, the stirring structure starts a stirring cycle mode, first stirring in the forward direction for a period of time, such as three to five minutes, then pausing stirring, such as fifteen to thirty seconds, and then stirring in the reverse direction for a period of time, such as three to five minutes, then pausing stirring, such as fifteen to thirty seconds, and then stirring in the forward direction for a period of time, such as three to five minutes, and finally stopping stirring, such as twenty to twenty-five minutes. This process is one cycle of the stirring cycle. In this way, the microorganisms and various mixed materials can be better mixed to form a microbial mixture, and during the stirring process, the moisture in the microbial mixture can be effectively discharged to ensure the activity of the microorganisms.

[0031] Preferably, the stirring method of controlling the third driving component 25 through the control component to drive the stirring shaft component 24 to rotate forward and reverse can avoid the accumulation of too much microbial mixture at one end of the fermentation box, ensuring that the microbial mixture can be evenly mixed and evenly distributed in the fermentation box.

[0032] Preferably, after the microorganisms and the mixed materials are put into the fermentation box for a period of time, about 24 hours later, The kitchen waste can be put into the kitchen waste treatment equipment, and then after the kitchen waste has passed the oil-water separation process, it enters the fermentation box. The stirring method is similar to the above-mentioned stirring cycle mode. The use of this forward and reverse stirring method can avoid excessive microbial mixing and the accumulation of kitchen waste at one end of the fermentation box, ensuring that the microbial mixture and the kitchen waste can be evenly mixed, thereby improving the degradation effect of microorganisms.

[0033] Preferably, the stirring structure stops stirring in order to provide sufficient time for the microbial mixture to degrade the kitchen waste. Moreover, by adopting this stirring cycle mode, the kitchen waste and the microbial mixture can be stirred in a timely manner to discharge moisture, thereby ensuring that the environment in which the microorganisms are located is always in a suitable humidity environment.

[0034] like Figures 1 to 5 As shown, the first secondary shaft 242 of this embodiment includes a shaft body 2421 and a blade 2422 arranged 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 2422 has a certain curvature.

[0035] The first secondary shaft includes an axis body and a paddle disposed at one end of the axis body, the paddle blade is used to stir the material in the fermentation chamber, the paddle blade is usually designed to maximize the stirring effect, and the paddle body has a certain curvature, which helps to provide greater stirring force and better fluid dynamics.

[0036] Preferably, the other end of the shaft body is connected to the main shaft, and this connection can be welding, threaded connection or other types of mechanical connection methods, ensuring that the first secondary shaft is stable during the stirring process and can withstand the force caused by the stirring. Through the blades on the first secondary shaft, the material in the fermentation chamber can be more effectively stirred, thereby accelerating the fermentation process. The curved blades are usually more efficient and can provide a strong stirring effect while consuming less energy.

[0037] like Figures 1 to 5 As shown, the paddle 2422 of this embodiment is in the shape of a shovel, which is similar to a shovel used in gardening tools, with a wide shovel surface and a certain curvature. This design helps to better push and turn over the materials during the stirring process, similar to the action of a shovel digging in the soil, thereby promoting the circulation and mixing of the materials in the fermentation chamber. The wide shovel surface and curvature of the paddle enable it to turn over the materials, turning the materials at the bottom to the surface, or pushing the materials on the surface to the bottom, thereby achieving uniform distribution and full contact of the materials.

[0038] Preferably, the other end of the shaft body and the main shaft 241 are an integrally formed structure or a detachable connection structure, and a suitable design can be selected according to actual needs.

[0039] like Figures 1 to 5 As shown, the main shaft 241 of this embodiment is also provided with two oppositely arranged second sub-shafts 243, and the two second sub-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 stirring dead corner and easily leads to material accumulation.

[0040] like Figures 1 to 5 As shown, the second auxiliary shaft 243 of this embodiment is T-shaped. The T-shaped second auxiliary shaft 243 has a larger stirring range. The T-shaped second auxiliary shaft 243 can stir and transport the kitchen waste and / or humus fertilizer in the dead corners at both ends of the fermentation box to avoid the accumulation of kitchen waste and / or humus fertilizer at both ends of the fermentation box.

[0041] Preferably, the second secondary shaft 243 and the main shaft 241 are an integrally formed structure or a detachably connected structure, and a suitable design can be selected according to actual needs.

[0042] Since a large amount of material usually accumulates at the corners of the inner walls at both ends of the fermentation chamber, the secondary shaft with a paddle body having a certain curvature usually cannot stir the material there. In fact, the weight of the material may cause the paddle blades 2422 on the secondary shaft to be damaged. In addition, since the secondary shaft is designed to be detachably connected to the main shaft, the secondary shaft is more easily affected by the weight of the material on the main shaft, resulting in positional displacement or the secondary shaft falling off the main shaft, affecting the normal operation of the secondary shaft.

[0043] Preferably, the T-shaped secondary shaft is more evenly stressed, reducing the stress concentration caused by single-point stress, thereby reducing the risk of damage to the secondary shaft and making it less likely to be damaged. With regard to the design in which the second secondary shaft 243 is detachably connected to the main shaft, the secondary shaft is not easily affected by the weight of the material on the main shaft, and is unlikely to be displaced or fall off the main shaft, thereby ensuring the normal operation of the secondary shaft.

[0044] like Figures 1 to 5 As shown, a main discharge port 26 and a collecting assembly 27 are provided on one side of the fermentation box 22 of this embodiment. The material in the fermentation box 22 can be transported and guided to the main discharge port 26 through the stirring shaft assembly 24 for discharge, and collected by the collecting assembly 27 .

[0045] Preferably, with the cooperation of the stirring shaft assembly 24 and the third driving assembly 25, the material in the fermentation box can be transported and guided to the main discharge port, and the material is discharged from the fermentation box through the main discharge port and enters the collecting assembly. The collecting assembly collects the material discharged from the main discharge port for subsequent processing or use.

[0046] 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.

[0047] Specifically, the design of the stirring shaft assembly 24 with the above-mentioned main shaft 241 and multiple first secondary shafts 242 spirally distributed along the shaft body of the main shaft 241 is adopted, so that the stirring structure has both stirring and conveying functions, making the structure of the food waste processing equipment more compact and eliminating the need to set up an additional conveying structure.

[0048] Specifically, the design of the main discharge port and the collection component enables the material to be easily collected, simplifying the subsequent processing process. The convenient collection method reduces manual intervention and improves the convenience and efficiency of management.

[0049] like Figures 1 to 5 As shown, the fermentation box 22 of this embodiment is provided with a second door component, which includes a second door 28 and a fourth drive assembly 29. The fourth drive assembly 29 can drive the second door 28 to block or keep the second door 28 away from the main discharge port 26.

[0050] Specifically, the second door component controls the opening and closing of the second door through the fourth driving assembly.

[0051] When the material needs to be discharged, the fourth driving assembly drives the second box door away from the main discharge port, so that the main discharge port is opened and the material can be discharged.

[0052] When material discharge is not required, the fourth driving assembly drives the second box door to block the main discharge port to prevent the material from being discharged.

[0053] When fermentation is completed or part of the material needs to be discharged, the control system starts the fourth drive component, and the fourth drive component drives the second box door to open the main discharge port, and the material is discharged through the main discharge port. After the discharge is completed, the fourth drive component drives the second box door to close the main discharge port to ensure the system is sealed.

[0054] Preferably, the fourth drive assembly can accurately control the opening and closing of the second door to ensure effective blocking or opening of the main discharge port. Combined with the control system, the opening and closing operation of the second door can be automated to reduce manual intervention.

[0055] like Figures 1 to 5 As shown, the collecting assembly 27 of this embodiment includes a collecting box located on one side of the fermentation box 22 , the top of the collecting box 271 has an opening, and the main discharge port 26 is located above the collecting box 271 .

[0056] Specifically, the material is discharged from the fermentation box through the main discharge port, and the main discharge port is located above the collecting box. The discharged material enters the collecting box through the opening at the top of the collecting box and is effectively collected by the collecting component. The design of the opening at the top of the collecting box simplifies the discharge and collection process of the material and reduces complex mechanisms. The user only needs to take away the collection box 271 that has collected the kitchen waste to complete the collection. It has the advantages of simple structure and easy operation.

[0057] like Figures 1 to 5 As shown, the collecting component 27 of this embodiment also includes a guide plate 272 arranged on one side of the fermentation box 22, and the guide plate 272 has a certain slope. The guide plate 272 can guide the material discharged from the main discharge port 26 to the collecting box 271. With such a design, the kitchen waste can accurately fall into the collecting box 271 from the main discharge port 26, ensuring the scattering of the kitchen waste, keeping the working environment clean and the accurate collection of the kitchen waste.

[0058] Preferably, the control component can be a control unit such as a touch screen, a control button, etc., and a suitable design can be selected according to actual needs.

[0059] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this.
