Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a stirring mechanism and a kitchen waste treatment device. Background Art

[0002] Kitchen waste is the most common waste generated in daily urban life. It has the characteristics of high water content, high oil and salt content, easy to rot and stink, and is not conducive to the transportation by ordinary garbage trucks. If such waste is not treated by classification, it will cause great harm to the environment. Therefore, some places with large amounts of kitchen waste, inconvenient transportation or remote locations, such as highway service areas, seafood markets, farmers' markets, etc., all need to be equipped with kitchen waste treatment devices to ferment and degrade kitchen waste.

[0003] A stirring mechanism is arranged in the kitchen waste treatment equipment to stir the kitchen waste in the equipment to ensure sufficient heating and degradation of the kitchen waste. The stirring mechanism includes a main shaft and stirring components arranged on the main shaft. The main shaft drives the stirring components to rotate, and the stirring components stir the kitchen waste. During the stirring process, the stirring components will bear great resistance. Thus, no matter what form the stirring components are arranged in, there is a probability of bending and breaking. If the stirring components are bent or broken, the stirring components need to be replaced.

[0004] One end of the stirring component of the stirring mechanism in the existing kitchen waste treatment equipment is a cylinder, and a cylindrical hole adapted to the cylinder is arranged on the main shaft. When connecting the main shaft and the stirring component, the cylinder needs to be inserted into the cylindrical hole and then fixed firmly. However, due to the high salt content in the kitchen waste, the stirring mechanism will react with the salt solution when soaking in the kitchen waste for a long time. The reaction will cause the cylinder to stick tightly to the main shaft. In this case, if the stirring component is deformed or broken, it is very difficult to take out the cylinder from the cylindrical hole, and it is difficult to replace the new stirring mechanism.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0022] Optionally, the stirring component further includes a limiting body;

[0023] The main body and the cone portion are arranged on both sides of the limiting body, and both the main body and the cone portion are connected to the limiting body;

[0024] When the stirring component is connected to the main shaft, the limiting body and the fastener are respectively limited on both sides of the main shaft.

[0025] Optionally, a groove is provided on the main shaft, and the groove is connected to the through groove;

[0026] When the stirring component is connected to the main shaft, the limiting body is embedded in the groove.

[0027] Optionally, the groove and the limiting body cooperate to limit each other, and the groove limits the position of the limiting body to prevent the limiting body from rotating around the axis of the stirring component.

[0028] The second object of the present application is to provide a kitchen waste treatment device, including:

[0029] A main machine, the main machine having a loading cavity;

[0030] A driving component, the driving component being arranged on the main machine;

[0040] For the stirring mechanism of the present application, the connection between the main shaft and the stirring component is in a tapered groove and a tapered part for cooperation. This cooperation structure has a certain guiding effect, making it easy for the tapered part to slip from the end with a smaller diameter to the end with a larger diameter. Thus, when it is necessary to replace the stirring component, after removing the fastening piece, even if there is adhesion between the inner wall of the tapered part and the tapered groove, when a force is applied axially from the end with a smaller diameter of the tapered part to the end with a larger diameter, the tapered part can easily be disengaged from the tapered groove. Moreover, this cooperation structure also has a limiting effect. When the tapered part extends inward from the wide end of the tapered groove by a certain distance, it can no longer move towards the narrow end of the tapered groove. The tapered part can be positioned in cooperation with the fastening piece without a limiting structure on the wide end side of the tapered groove.

[0056] Embodiment 1

[0057] See Figures 1 to 9As shown in the figure, an embodiment of the present application provides a stirring mechanism, including a main shaft 41, a stirring component, and a fastener 45. The main shaft 41 has a through groove 411 that penetrates the main shaft 41 in the radial direction of the main shaft 41, and the through groove 411 is a tapered groove. The stirring component includes a cone portion 421 and a main body portion 422. The cone portion 421 is connected to the main body portion 422. The cone portion 421 is inserted into the tapered groove, and the outer surface of the cone portion 421 fits with the inner surface of the tapered groove. The fastener 45 is detachably connected to the cone portion 421, and the fastener 45 and the main body portion 422 of this mating structure are respectively limited on both sides of the main shaft 41. In the stirring mechanism of this embodiment, the connection between the main shaft 41 and the stirring component is matched by a tapered groove and a cone portion 421. This mating structure has a certain guiding effect, making it easy for the cone portion 421 to slip off from the end with a smaller diameter to the end with a larger diameter. Thus, when it is necessary to replace the stirring component, after removing the fastener 45, even if the cone portion 421 is adhered to the inner wall of the tapered groove, when a force is applied axially from the end with a smaller diameter of the cone portion 421 to the end with a larger diameter, the cone portion 421 can easily be removed from the tapered groove. Furthermore, this mating structure also has a limiting effect. When the cone portion 421 extends inward from the wide end of the tapered groove by a certain distance, it can no longer move toward the narrow end of the tapered groove. The cone portion 421 can be positioned in cooperation with the fastener 45 without a limiting structure on the side of the wide end of the tapered groove.

[0058] In a possible implementation, the stirring component further includes a positioning and mating section 423. The positioning and mating section 423 is provided at an end of the cone portion 421 facing away from the main body portion 422. In a state where the stirring component is connected to the main shaft 41, the positioning and mating section 423 extends out of the tapered groove, and the fastener 45 is connected to the positioning and mating section 423. By providing a positioning section that extends out of the tapered groove, it is more convenient for the fastener 45 to be disassembled and assembled with the stirring part, making the installation, maintenance, and replacement of the stirring component more time-saving and labor-saving.

[0059] In a possible implementation, the positioning and mating section 423 has an external thread, and the fastener 45 has a thread groove. The fastener 45 is threadedly connected to the positioning and mating section 423. Using threaded connection can ensure stable connection and is also convenient for disassembly and assembly.

[0060] In a possible implementation, the fastener 45 includes at least two nuts. The nuts have the thread grooves, and each nut is threadedly connected to the positioning and mating section 423. Two nuts, one left-handed nut and one right-handed nut, are used in combination for tightening and loosening prevention. After the two nuts are tightened, the axial force generated between the nuts increases the frictional force between the nut teeth and the bolt teeth, thereby preventing the nuts from loosening automatically.

[0061] In a possible implementation, the stirring member further includes a limiting body 424. The main body portion 422 and the conical portion are disposed on both sides of the limiting body 424, and both the main body portion 422 and the conical portion are connected to the limiting body 424. In a state where the stirring member is connected to the main shaft 41, the limiting body 424 and the fastener 45 are respectively limited on both sides of the main shaft 41. The limiting body 424 further limits the length of the stirring member extending into the conical groove, preventing the conical portion 421 of the stirring member from extending excessively into the conical groove and causing damage to the conical portion 421 and the conical groove. Moreover, the limiting body 424 and the fastener 45 are respectively clamped from both sides of the main shaft 41, ensuring that the stirring member is not prone to shaking.

[0062] In a possible implementation, a groove 412 is provided on the main shaft 41, and the groove 412 communicates with the through groove 411. In a state where the stirring member is connected to the main shaft 41, the limiting body 424 is embedded in the groove 412. If the limiting body 424 protrudes from the outer surface of the main shaft 41, the limiting body 424 is easily collided and worn. Providing the groove 412 to embed the limiting body 424 in the groove 412 can protect the limiting body 424 and ensure the service life of the limiting body 424.

[0063] In a possible implementation, the groove 412 and the limiting body 424 are in limiting cooperation, and the groove 412 restricts the position of the limiting body 424 to prevent the limiting body 424 from rotating around the axis of the stirring member. The limiting body 424 can be a column with a polygonal cross-section, such as a quadrilateral, a pentagon, a hexagon, etc. The limiting body 424 can also be in the shape of a gear. The shape of the groove 412 matches the outer shape of the limiting body 424. The limiting body 424 is disposed in the groove 412, and the groove 412 restricts the entire stirring member through the limiting body 424, so that the stirring member will not rotate.

[0064] Preferably, the limiting body 424 is in the shape of a gear, and the edge of the groove 412 is in the shape of a gear adapted to the limiting body 424. In this way, when the stirring rod 42 is connected to the main shaft 41, the angle can be adjusted, and after adjusting to an appropriate angle, the installation can be carried out.

[0065] Embodiment 2

[0066] See Figures 1 to 9As shown in the figure, an embodiment of the present application provides a kitchen waste treatment device, which includes a main body, a driving component 10, and the stirring mechanism 4 in the first embodiment. The main body has a loading cavity, and the driving component 10 is arranged on the main body. At least a part of the stirring mechanism 4 is located in the loading cavity, and the main shaft 41 of the stirring mechanism 4 is connected to the driving component 10. The driving component 10 drives the main shaft 41 to rotate, and the main shaft 41 drives the stirring component to stir the kitchen waste. The kitchen waste treatment device of this embodiment uses the stirring mechanism 4 in the first embodiment. When the stirring component of the kitchen waste treatment device in this embodiment needs to be replaced, after removing the fastening piece 45, even if there is adhesion between the conical part 421 and the inner wall of the conical groove, applying force axially from the smaller-diameter end to the larger-diameter end of the conical part 421, the conical part 421 can easily be taken out of the conical groove, making the replacement of the stirring component simple and convenient.

[0067] In a possible implementation, the kitchen waste treatment device further includes a deodorization pipeline 9, which is arranged on the main body, and a blower 91 is arranged on the deodorization pipeline 9. The deodorization pipeline 9 communicates with the loading cavity. The deodorization pipeline 9 has a drain port 94 and an exhaust port. During the fermentation process of kitchen waste, odoriferous gases will be generated. To ensure a relatively hygienic environment and the oxygen supply in the loading cavity, a deodorization pipeline 9 communicating with the loading cavity is provided. The blower 91 on the deodorization pipeline 9 can extract the gas in the loading cavity out of the main body through the deodorization pipeline 9. An air inlet is also provided on the loading cavity. During the air extraction process of the blower 91, fresh air will enter through the air inlet. The fresh air not only has no odor but also has a relatively high oxygen content, which not only ensures the air circulation inside the loading cavity but also is more conducive to the fermentation of kitchen waste. And because a large amount of moisture is contained in the kitchen waste, a large amount of water vapor will be generated after being heated by the heating device 5. Since the deodorization pipeline 9 is far from the heating device 5, the temperature of the deodorization pipeline 9 is relatively low, and a certain amount of water vapor will condense into water in the deodorization pipeline 9. By providing a drain port 94 on the deodorization pipeline 9, the water in the deodorization pipeline 9 can be discharged, so as not to affect the normal operation of the blower 91 and the deodorization pipeline 9.

[0068] Furthermore, it further includes a drain pipe, which is communicated with the drain port 94. The water condensed in the deodorization pipeline 9 can be led out by the exhaust pipe 92 or collected by connecting a water storage container through the drain pipe, and then the water storage container can be cleaned regularly.

[0069] In a possible implementation, the deodorizing duct 9 includes a box body 93 and an exhaust pipe 92. An air outlet communicating with the charging cavity is provided on the main machine. The fan 91 is connected to the main machine. The air inlet of the fan 91 is connected to the air outlet, and the air outlet of the fan 91 communicates with the cavity of the box body 93. The exhaust pipe 92 is connected to the box body 93 and the exhaust pipe 92 communicates with the cavity of the box body 93. A drain port 94 is provided on the box body 93. By providing a box body 93 with a relatively large volume, a filtering device can be accommodated in the box body 93. The filtering device filters the discharged gas to prevent the discharged gas from having an overly strong odor or containing harmful substances, which may affect the normal life of people around.

[0070] Embodiment III

[0071] On the basis of Embodiment II, the stirring component of the kitchen waste treatment device includes a stirring rod 42 and several auxiliary rods 43. One end of the stirring rod 42 is connected to the main shaft 41, the auxiliary rod 43 is connected to the stirring rod 42, the auxiliary rod 43 is parallel to the main shaft 41, and at least one auxiliary rod 43 is located on the side of the stirring rod 42 away from the main shaft 41. The stirring mechanism for the waste gasification device provided in the present application, by providing an auxiliary rod parallel to the main shaft at the end of the stirring rod away from the main shaft, is more conducive to stirring the transition angle in the charging box, reducing or completely eliminating the adhesion of kitchen waste at the transition angle, making the stirring of kitchen waste in the charging box more sufficient, ensuring that the kitchen waste at the transition angle is also fully fermented, and reducing the occurrence of the situation where the kitchen waste at the transition angle decays and emits an odor.

[0072] In a possible implementation, the stirring mechanism 4 for the waste gasification device includes at least two auxiliary rods 43. Each of the auxiliary rods 43 is connected to the stirring rod 42, and the auxiliary rods 43 are sequentially arranged at intervals along the length direction of the stirring rod 42. By providing at least two auxiliary rods 43, with each auxiliary rod located at a different position in the radial direction of the main shaft, different positions along the radial extension line of the main shaft can be stirred, increasing the stirring area and making the stirring of kitchen waste more sufficient.

[0073] In a possible implementation, the stirring mechanism 4 for the waste gasification device further includes a stirring blade 44. The stirring blade 44 is connected to the side of the stirring rod 42 facing away from the main shaft 41, and the straight line where at least one of the auxiliary rods 43 is located penetrates through the stirring blade 44. The stirring blade 44 is relatively thin compared to the stirring rod 42. The stirring blade 44 is a sheet-like body extending along the circumferential direction of the rotation of the stirring component. The two ends of the stirring blade 44 are relatively pointed, which plays a role in reducing resistance during the rotation of the stirring mechanism 4 and can hardly drive the kitchen waste to move. By providing an auxiliary rod 43 in the area where the stirring blade 44 is located, the auxiliary rod 43 is closer to the transition angle area.

[0074] In a possible implementation, the auxiliary rod 43 includes two sub-rods 431. The two sub-rods 431 are arranged on both sides of the stirring rod 42, and both of the two sub-rods 431 are connected to the stirring rod 42. By dividing the auxiliary rod 43 into two sub-rods 431 and connecting them to both sides of the stirring rod 42 respectively, the length of the sub-rod 431 can be designed to be relatively small, which can make the auxiliary rod 43 stronger, with a small moment of force when stressed and not easily deformed when stressed.

[0075] In a possible implementation, the stirring mechanism 4 for the garbage gasification device includes a plurality of stirring rods 42. Each stirring rod 42 is connected to the main shaft 41, and the stirring rods 42 are sequentially arranged at intervals along the length direction of the main shaft 41. Arranging a plurality of stirring rods 42 along the length direction of the main shaft can stir the kitchen waste at multiple positions along the length direction of the main shaft in space, so that the kitchen waste in different regions can be stirred, and further improves the stirring effect on the kitchen waste.

[0076] In a possible implementation, the auxiliary rod 43 is provided on at least two ends of each stirring rod 42. The stirring rods 42 at both ends are closer to the dead corner area of the loading box. Therefore, setting the auxiliary rod 43 on the stirring rod 42 close to the side wall is most effective for stirring the kitchen waste at the dead corner. Further, the auxiliary rod is also provided on the stirring rod connected to the middle section of the main shaft, so that the kitchen waste in the middle section can also be fully stirred at various positions in the radial direction of the main shaft.

[0077] Example Four

[0078] See Figures 1 to 9 As shown, on the basis of Example Three, the main machine includes a chamfering part 23, a main housing 21, and two side housings 22 connected to both sides of the main housing 21. A transition angle is formed between the main housing 21 and the side housing 22. The chamfering part 23 is located at the transition angle and is connected to the inner wall of the main housing and / or the side housing. The chamfering part 23 is provided with an arc surface for smooth transition. An included angle is formed at the connection between the main housing 21 and the side housing 22. If the transition of the included angle is an angle of about 90 degrees, the kitchen waste that has been unable to be turned over easily remains there. Making the transition angle smooth at this place makes the kitchen waste at this place easily driven, further improving the sufficiency of stirring.

[0079] In a possible implementation, the chamfering part 23 has a first connection surface and a second connection surface. The arc surface is respectively connected to the first connection surface and the second connection surface. The first connection surface is attached to and connected to the side housing 22, and the second connection surface is attached to and connected to the main housing 21. The arc surface is exposed to the loading cavity. Using the first connection surface and the second connection surface to be connected to the side housing 22 and the main housing 21 respectively, this face-to-face connection method makes the connection more stable and not easily damaged when stressed.

[0080] In a possible implementation, end faces 24 with smooth transitions are provided at both ends of the chamfering member 23, and the end faces 24 are respectively connected to the main housing 21, the side housing 22, and the chamfering member 23. The two ends of the chamfering member 23 are the upward-facing end faces, and these end faces are set to have smooth transitions to prevent dead corners from forming at these locations and to prevent kitchen waste that cannot be turned over from accumulating. Based on the above, adding such a setting can maximize the stirring efficiency of the garbage gasification device.

[0081] Example Five

[0082] See Figures 1 to 9 As shown, on the basis of Example Four, it further includes a box housing 1, a heat-insulating housing 3, and a heating device 5. The box housing 1 has a cavity and a feed port 11 communicating with the cavity. The loading box 2 is disposed in the cavity. The loading box 2 has a loading cavity, and the loading cavity communicates with the feed port 11. The heat-insulating housing 3 is disposed in the cavity, and the heat-insulating housing 3 is located between the inner wall of the box housing 1 and the loading box 2, and the heat-insulating housing 3 is connected to the loading box 2. An oil storage cavity 6 is formed between the heat-insulating housing 3 and the loading box 2. The heating device 5 is disposed in the heat-insulating housing 3, and at least a part of the heating device 5 extends into the oil storage cavity 6. The heat-insulating housing 3 is provided, and an oil storage cavity is formed between the heat-insulating housing 3 and the loading box 2, and heat-insulating oil is accommodated in the oil storage cavity. During use, the heating device heats the heat-insulating oil. The heat-insulating oil has a good heat-insulating effect, and heat loss can be reduced during use, thereby reducing the energy consumption during use and saving energy. Moreover, the heat-insulating oil hardly generates loss during use, and there is no problem of malfunction of the heat-insulating oil, and almost no maintenance and repair are required for it, greatly extending the maintenance and repair cycle and reducing the material, time, and labor costs.

[0083] Among them, the heat-insulating oil can be one of transformer oil, lubricating oil, and heat-conducting oil.

[0084] In a possible implementation, the loading box 2 has a main housing 21 and a side housing 22. The heat-insulating housing 3 extends along the main housing 21, and the heat-insulating housing 3 is connected to the main housing 21. An oil storage cavity 6 and a side port communicating with the oil storage cavity 6 are formed between the heat-insulating housing 3 and the main housing 21. The side housing 22 is respectively connected to the main housing 21 and the heat-insulating housing 3, and closes the side port. The lower part of the main housing 21 of the loading box 2 is shared by the loading cavity and the oil storage cavity 6. The heat-insulating oil in the oil storage cavity 6 can directly contact the loading box 2, and the heat conduction effect is better. The oil storage cavity 6 requires to be sealed, the connection between the main housing 21 and the side housing 22 of the loading cavity requires to be sealed, the side housing 22 seals the side parts of both the loading box 2 and the oil storage cavity 6 at the same time, and the lower part of the main housing 21 is shared by the loading cavity and the oil storage cavity 6. Such a setting reduces the connection seams, reduces the connection difficulty, and ensures the sealing effect.

[0085] In a possible implementation, the main housing 21 includes two first flat walls 211 and a first arc-shaped bottom wall 212 connecting the two first flat walls 211. The heat preservation housing 3 extends along the first arc-shaped bottom wall 212, and the heat preservation housing 3 is connected to the first flat wall 211. An oil storage cavity 6 is formed at least between the heat preservation housing 3 and the first arc-shaped bottom wall 212. After the kitchen waste enters the loading box 2, it will flow to the bottom of the loading box 2 and is mainly carried and wrapped by the arc-shaped bottom wall.
