Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] likeFigure 1 As shown, the food waste disposer proposed in this embodiment includes a box frame 1, a box panel 3 fixedly connected to the outer wall of the box frame 1, a support body 29 fixedly connected to the inner wall of the box frame 1, a multi-functional stir-frying component provided on the outer wall of the support body 29, and symmetrically distributed fuma wheels 2 fixedly connected to the outer wall of the box frame 1 for easy movement.

[0046] like Figure 2 , Figures 6 to 9 As shown, it also includes a feeding and grinding assembly, which includes a feeding hopper 4 fixedly connected to the outer wall of the housing frame 1. A grinding chamber 5 is fixedly connected to the outer wall of the feeding hopper 4. Evenly distributed grinding teeth 8 are fixedly connected to the inner wall of the grinding chamber 5. A sealing base plate 6 is fixedly connected to the outer wall of the grinding chamber 5. A drive motor 7 is fixedly connected to the outer wall of the sealing base plate 6. A rotating column 9 is fixedly connected to the output end of the drive motor 7. A turntable 10 is fixedly connected to the outer wall of the rotating column 9. A grinding blade 11 is fixed on the turntable 10. The turntable is also equipped with a quick-release fixing device. The kitchen waste processor also includes a multi-functional stir-frying assembly connected to the feeding and grinding assembly via a pipe. The multi-functional stir-frying assembly is also connected to a self-cleaning oil-water separation assembly.

[0047] After the food waste is put in, it first enters the feed hopper 4 and then falls into the grinding chamber 5. The drive motor 7 starts, and its output end drives the rotating column 9 to rotate. The rotating column 9 then drives the turntable 10 to rotate. The grinding blades 11 on the turntable 10 rotate accordingly. During the rotation, the grinding blades 11 interact with the grinding teeth 8 on the inner wall of the grinding chamber 5 to fully grind and crush the food waste, so that large pieces of food waste such as bones and plant tubers are broken into smaller particles.

[0048] The ground kitchen waste is a mixture of small solid particles and liquid. As the turntable 10 rotates, it is thrown into the multi-functional stir-frying component through the connecting pipe 23 to stir-fry and remove moisture.

[0049] like Figures 11 to 15 As shown, in a preferred embodiment, the multifunctional stir-fry assembly includes a solid-liquid separation box 24 fixedly connected to the outer wall of the support body 29 and connected to the connecting pipe 23. The outer wall of the solid-liquid separation box 24 has an organic matter discharge hole 38. The solid-liquid separation box 24 is rotatably connected to a drive rod 27. A stir-frying plate 35 is fixedly connected to the outer wall of the drive rod 27. An inner discharge plate 36 is rotatably connected to the outer wall of the solid-liquid separation box 24. An anti-rotation block 39 is fixedly connected to the outer wall of the inner discharge plate 36. The top of the inner discharge plate is made of steel. An outer discharge plate 30 is fixedly connected to the outer wall of the solid-liquid separation box 24. An electromagnetic head 37 is fixedly connected to the outer wall of the solid-liquid separation box 24. The installation height of the electromagnetic head 37 is lower than the top height of the inner discharge plate 36 when it is in the closed solid-liquid separation box, that is, the top height of the inner discharge plate 36 when it is usually in a roughly vertical position.

[0050] The multi-functional stir-frying assembly also includes an angle detection device for detecting the rotation angle of the stir-frying plate, and the kitchen waste processor also includes a controller, which is signal-connected to the angle detection device, the electromagnetic head, and the drive rod.

[0051] The ground waste particles enter the solid-liquid separation box 24 through the connecting pipe 23. The drive rod 27 rotates under the drive of the output end of the reduction motor 26. The stirring plate 35 on the drive rod 27 rotates accordingly, continuously stirring the kitchen waste particles in the solid-liquid separation box 24. During the stirring process, the inner discharge plate 36 is attracted by the electromagnetic head 37 and keeps it in a vertical position, so as not to obstruct the rotation of the stirring plate.

[0052] In a preferred embodiment, a high-temperature drying hot air blower 32 is slidably connected to the top wall of the solid-liquid separation box 24. The high-temperature drying hot air blower 32 starts working when stir-frying, blowing out high-temperature hot air to dry the garbage. During the drying process, it can also play a role in sterilization and disinfection.

[0053] During the stir-frying and drying process, the liquid components in the waste flow out through the organic matter drain hole 38 on the solid-liquid separation box 24 and enter the feed box 31. Then, the feed box 31 guides the waste into the organic matter recovery box 28 for temporary storage. The oil and water can pass through the filter screen (not shown in the figure) in the organic matter recovery box 28 and directly enter the oil-water heating separation box 40 for oil-water separation.

[0054] The controller is connected to the motor that drives the drive rod, the electromagnetic head, and the angle detection device. Figure 15 In the specific embodiment shown, the angle detection device includes a magnetic block 33 and a Hall effect sensor 34 installed at the end of the drive rod; by pre-setting the stirring interval, for example, discharging once every 3 minutes of stirring, when the controller counts that 3 minutes have passed since the last discharge, angle detection and discharge begin. The discharge process is as follows: after reaching the stirring interval, if... Figure 13 and Figure 14 As shown, when the magnetic block 33 rotates counterclockwise to the preset first flip angle A1 for the first time with the drive rod, the first flip angle A1 is generally when the stirring plate has just rotated past the bottom of the inner discharge plate. At this time, the position of the stirring plate will not block the inner discharge plate from falling, nor will it block the discharge port. When the Hall effect sensor 34 detects that the angle of the drive rod calibrated by the magnetic block has reached A1, the controller causes the electromagnetic head 37 to be de-energized. After losing the magnetic attraction, the inner discharge plate 36 rotates downward under its own gravity, as shown. Figure 13 and Figure 14 As shown, the inner discharge plate 36 rotates until it is blocked and limited by the anti-rotation block 39 installed at the bottom of the inner discharge plate shaft, and stops rotating. The side wall formed by the inner discharge plate in the vertical state is empty to form a discharge channel. At this time, the stirring plate 35 continues to rotate counterclockwise, pushing the remaining solid waste after solid-liquid separation to the discharge port and discharging it along the outer discharge plate 30.

[0055] The rotating shaft of the inner discharge plate 36 can also be a limiting bearing that can only rotate a certain angle, achieving the same function as the anti-rotation block 39, so that the inner discharge plate can only rotate downwards to a certain angle.

[0056] When the Hall effect sensor detects that the drive rod has rotated to the preset second flip angle A2 for the second time, the stirring plate 35 changes its rotation direction, as follows: Figure 13 The device begins to rotate clockwise. Simultaneously, the controller energizes the electromagnetic head to generate magnetic force. During rotation, the stirring plate 35 contacts and lifts the inner discharge plate 36. When the inner discharge plate 36 is lifted back to a near-vertical position by the stirring plate, the top of the steel inner discharge plate 36 is attracted and fixed by the electromagnetic head 37, thus restoring the closed state of the solid-liquid separation tank 24. During the lifting process, the waste accumulated on the inner discharge plate is further pushed outward for the next round of waste stirring. During the discharge process, the controller can simultaneously control the grinding chamber 5 to pause rotation to prevent unstirred waste from being discharged directly, until the discharge port closes again.

[0057] A2 can be set to A1+△, where △ is the stirring interval. If there is only one stirring plate and its length is the radius of the rotation circle during stirring, △ can be set relatively large, close to one full circle, for example, 300-345 degrees. If there are multiple stirring plates, for example... Figure 13 , Figure 14 In the specific implementation shown, there are two stir-frying plates, which are located on the same plane. The angle △ can be set below half a circle, such as between 150-165 degrees. This allows for better removal of waste while preventing the inner discharge plate from falling and the stir-frying plate from being blocked by the discharge plate.

[0058] The design of the inner discharge plate enables the stirring operation in the solid-liquid separation box 24 to achieve closed operation and timed discharge during stirring. This avoids the situation in the existing design where the discharge port is always open, causing some kitchen waste with excessive water content to be directly processed into subsequent steps. The opening and closing of the discharge port is achieved by using the stirring plate and the electromagnetic head. The structure is simple and reliable. The stirring action of the stirring plate can achieve stirring, and with the cooperation of the inner discharge plate, the rotation of the stirring plate can also achieve discharge. The inner discharge plate also acts as a baffle during discharge, so that the kitchen waste after stirring is smoothly pushed out of the discharge port by the stirring plate.

[0059] The electromagnetic head can preferably be located inside the side wall above the stirring zone of the solid-liquid separation tank 24, protruding inward by a certain distance, so that the vertical projection of the electromagnetic head is closer to the rotating axis of the stirring plate relative to the inner discharge plate. Figure 14As shown, this design causes the inner discharge plate to tilt slightly inward when in a vertical position. This not only prevents it from obstructing the stir-frying plate, but also makes it easier for the inner discharge plate to fall under gravity when the electromagnetic head is de-energized. In addition, it makes the upper part of the inner discharge plate closer to the electromagnet during resetting, making it easier to be attracted and fixed.

[0060] To facilitate the disassembly and replacement of the grinding blade 11 in the feeding grinding assembly, in a preferred embodiment, the turntable 10 is further provided with a plurality of symmetrically distributed connecting holes 12. A connecting post 15 is fixed within each connecting hole 12, the grinding blade 11 is fixed above the connecting post 15, and a limit quick-release assembly is connected below the connecting post 15. Figures 8 to 10 As shown, the quick-release limiting assembly includes a circular guide rail 14 fixedly connected to the bottom of the turntable 10. A limiting plate 19 is rotatably connected to the outer wall of the circular guide rail 14. A symmetrically distributed locking block 20 is fixedly connected to the outer wall of the limiting plate 19, and the locking block 20 and the locking groove 16 are engaged with each other. A symmetrically distributed positioning rod 21 is slidably connected to the outer wall of the limiting plate 19, and the positioning rod 21 is slidably connected to the positioning hole 13. A tension spring 22 is sleeved on the outer wall of the positioning rod 21, and the lower end of the tension spring 22 is fixedly connected to the limiting plate 19. The end of the tension spring 22 away from the limiting plate 19 is fixedly connected to the positioning rod 21.

[0061] During normal operation of the equipment, the limiting plate 19 is rotatably connected to the outer wall of the turntable 10 via the circular guide rail 14. The locking block 20 connected to the limiting plate 19 and the locking groove 16 on the connecting column 15 engage with each other, limiting the connecting column 15 and thus fixing the grinding blade 11. The tension spring 22 is in a stretched state, generating a contraction force. Under the contraction force of the tension spring 22, one end of the positioning rod 21 is slidably connected to the outer wall of the limiting plate 19, and the other end is inserted into the positioning hole 13 of the turntable 10. Through the cooperation of multiple positioning holes 13 and positioning rod 21, the position of the limiting plate 19 is positioned to prevent the limiting plate 19 from shaking during the rotation of the turntable 10. The contraction force of multiple tension springs 22 ensures that the positioning rod 21 is fixed in the positioning hole 13, thereby fixing the entire limiting plate 19 and making the locking block 20 stably engaged in the locking groove 16, preventing the grinding blade 11 from shifting.

[0062] When the grinding blade 11 needs to be replaced, the operator pulls the positioning rod 21 outward, stretching the tension spring 22. The positioning rod 21 disengages from the positioning hole 13, releasing the positioning restriction on the limiting plate 19. Then, the limiting plate 19 is rotated along the circular guide rail 14, causing the locking block 20 to disengage from the slot 16. At this point, the connecting post 15 is no longer restricted and can be directly removed from the connecting hole 12, completing the disassembly of the grinding blade 11. After replacing the grinding blade 11, the limiting plate 19 is rotated in the opposite direction, causing the locking block 20 to disengage from the slot 16. 0. Reinsert the locating rod 21 into the slot 16, release the positioning rod 21, reset the tension spring 22, pull the positioning rod 21 back into the positioning hole 13, and reposition the limiting plate 19, completing the installation and fixation of the grinding blade 11. This simplifies the replacement operation of the grinding blade 11. The grinding blade 11 can be quickly disassembled and assembled by pulling the positioning rod 21 and rotating the limiting plate 19, without complicated tools and cumbersome steps, reducing maintenance time and labor costs, ensuring that the equipment can quickly return to operating status, and improving the maintenance efficiency of the equipment. At the same time, the fixing of the grinding blade 11 utilizes the elasticity of multiple tension springs 22, making the fixing method of the grinding blade 11 slightly elastic. When the kitchen waste contains sand, glass, and other hard materials that are mixed with soft kitchen waste such as vegetable leaves, making them difficult to break, the blade will undergo slight displacement under the resistance of these hard materials, avoiding direct hard damage to the blade.

[0063] The self-cleaning oil-water separator is used to separate the oil and water mixture discharged through the organic matter recovery tank 28 during the stir-frying process, such as... Figures 16 to 18 The diagram illustrates a specific embodiment of a self-cleaning oil-water separation assembly. The assembly includes an oil-water heating separation chamber 40 fixedly connected to the inner wall of a frame 1. The oil-water heating separation chamber is connected to an grease discharge pipe 46. It also includes a purification chamber 47 connected to the oil-water heating separation chamber 40. A pair of sealing side plates 49 are snapped onto the outer wall of the purification chamber 47. Evenly distributed clamping plates 50 are fixedly connected between the pair of sealing side plates 49. A honeycomb filter plate 51 is slidably connected between adjacent clamping plates 50. A collection drain pipe 48 is fixedly connected to the outer wall of the purification chamber 47.

[0064] The oil and water liquid in the organic matter recovery box 28 enters the oil-water heating and separation box 40 through a pipe (not shown in the figure). The oil-water heating and separation box 40 heats the liquid inside and uses the density difference between oil and water to achieve oil-water separation. The separated grease is located above the liquid and is discharged through the upper grease discharge pipe 46 for recycling, while the water below the liquid enters the lower purification box 47.

[0065] The outer wall of the purification box 47 is fixedly connected to a collection drain pipe 48. The water entering the purification box 47 passes through the honeycomb filter plate 51 during the flow process. The honeycomb filter plate 51 filters and purifies the impurities in the water. The purified water is finally discharged through the collection drain pipe 48. When it is necessary to disassemble and replace the honeycomb filter plate 51, it is only necessary to remove the sealing side plate 49 and pull the honeycomb filter plate 51 out of the card plate 50.

[0066] like Figure 12 As shown, in a preferred embodiment, based on the above method, a guide box 31 is fixedly connected to the outer wall of the solid-liquid separation tank 24, which has an organic matter discharge hole 38. An organic matter recovery tank 28 is fixedly connected to the bottom of the guide box 31, and the organic matter recovery tank 28 is connected to the oil-water heating separation tank 40. The liquid separated by stirring in the solid-liquid separation tank 24 flows into the guide box 31 through the organic matter discharge hole 38. The guide box 31 guides the liquid to the organic matter recovery tank 28 for temporary storage. The temporarily stored liquid then enters the oil-water heating separation tank 40 through the connecting structure for subsequent processing. This not only realizes the orderly collection and transportation of liquid after solid-liquid separation, ensuring the continuity of the liquid processing link, but also, since the stirring process in this invention can be carried out intermittently, the temporary storage function of the organic matter recovery tank 28 avoids the liquid from directly entering the oil-water heating separation tank 40 and causing impact, thereby improving the oil-water separation efficiency.

[0067] like Figure 5 As shown, in a preferred embodiment, based on the above method, a connecting pipe 23 is fixedly connected to the outer wall of the grinding chamber 5, and the connecting pipe 23 is connected to the solid-liquid separation box 24. The ground particles enter the solid-liquid separation box 24 through the connecting pipe 23 for solid-liquid separation operation.

[0068] like Figure 11 As shown, in a preferred embodiment, based on the above method, a mounting frame 25 is fixedly connected to the outer wall of the solid-liquid separation tank 24, and a geared motor 26 is fixedly connected to the outer wall of the mounting frame 25. The output end of the geared motor 26 is fixedly connected to the drive rod 27, and the drive rod 27 is driven to rotate through the output end of the geared motor 26.

[0069] like Figure 9 and Figure 10As shown, in a preferred embodiment, based on the above method, a hexagonal limiting block 17 is fixedly connected to the outer wall of the grinding blade 11, and the hexagonal limiting block 17 is slidably connected to the hexagonal limiting hole 18. When the grinding blade 11 is installed, the hexagonal limiting block 17 is embedded in the hexagonal limiting hole 18, which restricts the grinding blade 11 from rotating and shifting during operation, ensuring that it accurately cooperates with the grinding teeth 8 for grinding. This structure not only ensures the stability of the grinding blade 11 during operation and improves the grinding effect, but also facilitates the quick positioning and installation of the grinding blade 11 through sliding cooperation. In conjunction with the limiting quick-release component, it further simplifies the disassembly and assembly process.

[0070] Specifically, when this food waste processor is in use: after food waste is put in, it first enters the feed hopper 4, and then falls into the grinding chamber 5. The drive motor 7 starts, and its output end drives the rotating column 9 to rotate. The rotating column 9 then drives the turntable 10 to rotate. The grinding blades 11 on the turntable 10 rotate accordingly. During the rotation, the grinding blades 11 interact with the grinding teeth 8 on the inner wall of the grinding chamber 5 to fully grind and crush the food waste, so that large pieces of waste are broken into smaller particles. The ground waste particles enter the solid-liquid separation box 24 through the connecting pipe 23.

[0071] Driven by the output of the geared motor 26, the drive rod 27 rotates, and the stirring plate 35 rotates accordingly, continuously stirring the garbage in the solid-liquid separation box 24. During the stirring and drying process, the liquid components in the garbage flow out through the organic matter discharge hole 38 on the solid-liquid separation box 24 and enter the guide box 31. Then, the guide box 31 guides the garbage into the organic matter recovery box 28 for temporary storage. The oil and water can be directly separated by the filter screen in the organic matter recovery box 28 into the oil-water heating separation box 40.

[0072] As the drive rod 27 rotates, the stir-frying operation is carried out. After the stir-frying plate rotates several times and reaches the set stir-frying time T, the material is discharged. As the stirring plate continues to rotate, when the Hall effect sensor 34 detects that the magnetic block 33 has rotated to the preset angle A1, the electromagnetic head 37 is de-energized and loses its magnetic force. The inner discharge plate 36 rotates downward under its own gravity until it is blocked and limited by the anti-rotation block 39, forming a downward-sloping discharge channel. At this time, the stirring plate 35 continues to rotate counterclockwise, pushing the remaining solid waste after solid-liquid separation towards the discharge port and discharging it along the outer discharge plate 30. When the Hall effect sensor detects that the drive rod has rotated to the preset angle A2, the stirring plate 35 changes its rotation direction and begins to rotate clockwise. At the same time, the electromagnetic head 37 is energized and generates magnetism. During the rotation, the stirring plate 35 contacts the inner discharge plate 36 and lifts it up. When the inner discharge plate 36 returns to its initial position, the electromagnetic head 37 approaches the inner discharge plate 36 and adsorbs and fixes it, thereby restoring the sealed state of the solid-liquid separation box 24 for the next round of waste processing.

[0073] The liquid in the organic matter recovery tank 28 enters the oil-water heating and separation tank 40 through a pipe. The oil-water heating and separation tank 40 heats the liquid inside and uses the density difference between oil and water to achieve oil-water separation. The separated oil is discharged through the oil discharge pipe 46 for recycling, while the separated water enters the purification tank 47.

[0074] Water entering the purification tank 47 passes through the honeycomb filter plate 51 during its flow. The honeycomb filter plate 51 filters and purifies the impurities in the water. The purified water is finally discharged through the collection drain pipe 48. When it is necessary to disassemble and replace the honeycomb filter plate 51, simply remove the sealing side plate 49 and pull the honeycomb filter plate 51 away from the card plate 50.

[0075] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0076] 1. The design of the limit quick-release component makes the replacement of the grinding blade simple and quick. When the grinding blade needs to be replaced, the limit quick-release component can be operated to quickly release the limit on the connecting column, thereby facilitating the removal and replacement of the grinding blade. This reduces maintenance time and costs, ensures continuous and stable operation of the equipment, and at the same time, the cooperation of multiple positioning holes and positioning rods positions the limit plate, effectively preventing the locking blocks on the positioning plate from shaking or falling out of the slot, making the connection more stable and secure.

[0077] 2. By setting an angle detection device, the rotation angle of the drive rod can be accurately detected, thereby realizing the automatic opening and closing of the inner discharge plate. In conjunction with the stir-frying plate, the solid waste discharge process can be completed efficiently. The degree of automation is high, reducing manual operation. It solves the problem that in the existing technology of kitchen waste treatment, the discharge of solid waste mostly relies on manual operation or simple mechanical control, resulting in low automation and easy incomplete discharge or blockage.

[0078] 3. The self-cleaning oil-water separation component can efficiently separate oil and water by heating and utilizing the density stratification of oil and water. The separated oil can be recycled, improving resource utilization. The separated water is discharged after purification, reducing environmental pollution.

[0079] 4. By integrating multiple functions such as grinding, solid-liquid separation, oil-water separation, and purification, the equipment can handle kitchen waste in one stop without the need for additional equipment, thus reducing the footprint of the equipment and lowering the operating costs.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
