Description

Technical Field

[0002] Kitchen waste refers to the garbage generated in residents' daily lives and food processing, catering services, unit meals and other activities. It mainly includes discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea dregs, bones, etc. Its characteristics are high water content, easy to rot and deteriorate, and contains a large amount of organic matter. If kitchen waste is not handled in time, it will breed bacteria and produce odor in a short time, which will not only pollute the environment but also spread diseases. At the same time, a large amount of kitchen waste will be randomly piled up or landfilled, which will occupy land resources, and the organic matter in it cannot be effectively utilized, resulting in waste of resources. Therefore, special food waste disposers are needed to treat it scientifically to achieve reduction, harmlessness and resource utilization.

The grinding knife is a consumable part and needs to be replaced after long-term use, but the traditional fixing method is cumbersome to operate and the replacement process takes a long time, which increases the maintenance time and cost of the equipment and affects the continuous and stable operation of the equipment. The fixing structure is prone to loosening, resulting in a decrease in the grinding effect; 2. During the food waste processing and frying process, the discharge of solid waste mostly relies on manual operation or simple mechanical control, with a low degree of automation, and is prone to incomplete discharge or jamming.

[0020] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in 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 part of the embodiments of the present invention, not all of them.

[0021] like Figure 1 As shown, a food waste disposer proposed in this embodiment includes a box frame 1, the outer wall of the box frame 1 is fixedly connected to a box plate 3, the inner wall of the box frame 1 is fixedly connected to a support body 29, and the outer wall of the support body 29 is provided with a multifunctional stir-fry component. For easy movement, the outer wall of the box frame 1 is fixedly connected to symmetrically distributed Formosa wheels 2.

[0022] like Figure 2 、 Figures 6 to 9As shown, it also includes a feed grinding assembly, which includes a feed hopper 4 fixedly connected to the outer wall of the box frame 1, a grinding bin 5 fixedly connected to the outer wall of the feed hopper 4, and evenly distributed grinding teeth 8 fixedly connected to the inner wall of the grinding bin 5, a sealing bottom plate 6 fixedly connected to the outer wall of the grinding bin 5, a driving motor 7 fixedly connected to the outer wall of the sealing bottom plate 6, a rotating column 9 fixedly connected to the output end of the driving motor 7, and a turntable 10 fixedly connected to the outer wall of the rotating column 9, a grinding knife 11 is fixed to the turntable 10, and a quick-release fixing device is also provided; the food waste disposer also includes a multifunctional stir-frying assembly connected to the feed grinding assembly pipeline, and the multifunctional stir-frying assembly is also connected to a self-cleaning oil-water separation assembly.

[0023] After the food waste is put into the machine, it first enters the feed hopper 4 and then falls into the grinding chamber 5. The drive motor 7 is started, and its output end drives the rotating column 9 to rotate. The rotating column 9 then drives the turntable 10 to rotate, and the grinding blade 11 on the turntable 10 rotates accordingly. During the rotation process, the grinding blade 11 interacts 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.

[0024] The ground kitchen waste is a mixture of small solid particles and liquid. During the rotation of the turntable 10, it is thrown into the multifunctional stir-frying component through the connecting pipe 23 for stir-frying to remove moisture.

[0025] like Figures 11 to 15 As shown, as a preferred embodiment, the multifunctional stir-frying component 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 is provided with an organic matter discharge hole 38, the solid-liquid separation box 24 is rotatably connected to the drive rod 27, the outer wall of the drive rod 27 is fixedly connected to the stir-frying plate 35, the outer wall of the solid-liquid separation box 24 is rotatably connected to the inner discharge plate 36, the outer wall of the inner discharge plate 36 is fixedly connected to the anti-rotation block 39, the top of the inner discharge plate is made of steel material, the outer wall of the solid-liquid separation box 24 is fixedly connected to the outer discharge plate 30, the outer wall of the solid-liquid separation box 24 is fixedly connected to the electromagnetic head 37, and the installation height of the electromagnetic head 37 is lower than the top height of the inner discharge plate 36 when it is in a closed solid-liquid separation box, that is, the top height of the inner discharge plate 36 is generally approximately in a vertical position.

[0026] The multifunctional stir-frying assembly further includes an angle detection device for detecting the rotation angle of the stir-frying plate. The food waste disposer further includes a controller, which is connected to the angle detection device, the electromagnetic head, and the drive rod signal.

[0027] The ground garbage particles enter the solid-liquid separation box 24 through the connecting pipe 23, and the driving rod 27 rotates under the drive of the output end of the reduction motor 26. The stir-frying plate 35 on the driving rod 27 rotates accordingly, and the food waste particles in the solid-liquid separation box 24 are continuously stir-fried. During the stir-frying process, the inner discharge plate 36 is adsorbed by the electromagnetic head 37 and is in a vertical state, which will not hinder the rotation of the stir-frying plate.

[0028] 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 during stir-frying, blowing out high-temperature hot air to dry the garbage, and can also play a role in sterilization during the drying process.

[0029] During the stir-frying and drying process, the liquid components in the garbage flow out through the organic matter discharge holes 38 on the solid-liquid separation box 24 and enter the material guide box 31. Then, the material guide box 31 guides the garbage 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.

[0030] The controller is connected to the motor, electromagnetic head and angle detection device that drives the driving rod. 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 driving rod; by pre-setting the stir-frying interval, for example, the material is discharged every 3 minutes of stir-frying, and when the controller counts that the stir-frying time has reached 3 minutes since the last discharge, the angle detection and discharge process are started. After the stir-frying interval is reached, the material is discharged. Figure 13 and Figure 14 As shown, when the magnetic block 33 rotates counterclockwise with the driving rod for the first time to the preset first flip angle A1, the first flip angle A1 is generally when the stir-fry plate just rotates over the bottom of the inner discharge plate. At this time, the position of the stir-fry plate will not block the falling of the inner discharge plate, nor will it block the discharge port; when the Hall effect sensor 34 detects that the driving rod angle calibrated by the magnetic block reaches A1, the controller cuts off the power to the electromagnetic head 37. After losing the magnetic attraction, the upper part of the inner discharge plate 36 rotates and falls downward under the action of its own gravity, as shown in FIG. Figure 13 and Figure 14 As shown, the inner discharge plate 36 rotates until it is blocked by the anti-rotation block 39 installed at the bottom shaft of the inner discharge plate and no longer rotates. The side wall formed in the vertical state of the inner discharge plate is left empty to form a discharge channel. At this time, the stir-frying plate 35 continues to rotate counterclockwise, pushing the solid waste remaining after solid-liquid separation to the discharge port and discharge it along the outer discharge plate 30.

[0031] The rotating shaft of the inner discharge plate 36 can also adopt a limit bearing that can only rotate to a certain angle, achieving the same function as the anti-rotation block 39, so that the inner discharge plate can only rotate downward to a certain angle.

[0032] When the Hall effect sensor detects that the driving rod rotates to the preset second flip angle A2 for the second time, the stir-fry plate 35 changes its rotation direction, such as Figure 13 As shown, the machine starts to rotate clockwise, and the controller controls the electromagnetic head to generate magnetic force. During the rotation process, the stir-frying plate 35 contacts and lifts the inner discharge plate 36. When the inner discharge plate 36 is lifted back to a nearly vertical state by the stir-frying plate, the top of the steel inner discharge plate 36 is attracted and fixed by the electromagnetic head 37, thereby restoring the closed state of the solid-liquid separation box 24. During the lifting process, the garbage accumulated on the inner discharge plate is further pushed outward for the next round of garbage stir-frying. During the discharge process, the controller can also control the grinding chamber 5 to stop rotating to prevent the unstirred garbage from being discharged directly until the discharge port is closed again.

[0033] A2 can be set to A1+△, △ is the stir-fry interval. If there is only one stir-fry plate and its length is the radius of the rotating circle during stir-frying, △ can be set larger, that is, close to one circle, such as 300-345 degrees; if there are multiple stir-fry plates, such as Figure 13 、 Figure 14 In the specific embodiment shown, the stir-frying plate is composed of two pieces, and the two pieces are located on the same plane, so △ can be set below half a circle, such as between 150-165 degrees. On the one hand, it can better push out the garbage, and at the same time it will not block the falling of the inner discharge plate and the stir-frying plate from being blocked by the discharge plate.

[0034] Through the design of the inner discharge plate, the stir-frying operation in the solid-liquid separation box 24 can be closed and discharged at a fixed time during stir-frying, avoiding the existing design in which the discharge port is always open, resulting in excessive water content in some food waste, and directly proceeding to subsequent steps. The discharge port is opened and closed by cooperating with the stir-frying plate and the electromagnetic head. The structure is simple and reliable. The stir-frying action of the stir-frying plate can achieve stir-frying. With the cooperation of the inner discharge plate, the rotation of the stir-frying plate can also achieve discharge. The inner discharge plate also serves as a baffle during discharge, so that the food waste after stir-frying is smoothly pushed out of the discharge port by the stir-frying plate.

[0035] The electromagnetic head can be preferably arranged inside the side wall above the stir-frying zone of the solid-liquid separation box 24, protruding inward by a certain distance, so that the electromagnetic head is projected in the vertical direction closer to the rotation axis of the stir-frying plate relative to the rotation axis of the inner discharge plate, such as Figure 14 As shown, this design makes the inner discharge plate tilt slightly inward when in a vertical state, so that it will not block the stir-fry plate, and it can also make the inner discharge plate fall more easily under the action of gravity when the electromagnetic head is powered off. At the same time, it also makes the upper end of the inner discharge plate closer to the electromagnet when resetting, and it is easier to be adsorbed and fixed.

[0036] In order to facilitate the disassembly and replacement of the grinding blade 11 in the feed grinding assembly, as a preferred embodiment, the turntable 10 is further provided with a plurality of symmetrically distributed connecting holes 12, wherein connecting posts 15 are fixed in the connecting holes 12, the grinding blade 11 is fixed above the connecting posts 15, and a limited position quick release assembly is connected below the connecting posts 15; Figures 8 to 10 As shown, the limit quick-release assembly includes a circular guide rail 14 fixedly connected to the bottom of the turntable 10, the outer wall of the circular guide rail 14 is rotatably connected to the limit plate 19, the outer wall of the limit plate 19 is fixedly connected with symmetrically distributed clamping blocks 20, and the clamping blocks 20 and the clamping slots 16 are mutually clamped, the outer wall of the limit plate 19 is slidably connected with symmetrically distributed positioning rods 21, and the positioning rods 21 are slidably connected to the positioning holes 13, the outer wall of the positioning rod 21 is sleeved with a tension spring 22, and the lower end of the tension spring 22 is fixedly connected to the limit plate 19, and the end of the tension spring 22 away from the limit plate 19 is fixedly connected to the positioning rod 21.

[0037] The contraction force of multiple tension springs 22 ensures that the positioning rod 21 is fixed in the positioning hole 13, so that the limit plate 19 is fixed as a whole, and the block 20 connected to the limit plate 19 is stably connected to the slot 16 to prevent the grinding knife 11 from moving.

[0038] When the grinding blade 11 needs to be replaced, the operator pulls the positioning rod 21 outward, the tension spring 22 is stretched, the positioning rod 21 is disengaged from the positioning hole 13, and the positioning restriction of the limit plate 19 is released. Then, the limit plate 19 is rotated to rotate along the circular guide rail 14, driving the block 20 to disengage from the slot 16. At this time, the connecting column 15 is no longer restricted and can be directly taken out of the connecting hole 12. The disassembly of the grinding blade 11 is completed. After replacing the new grinding blade 11, the limit plate 19 is rotated in the opposite direction to make the block 20 0 is re-engaged in the slot 16, the positioning rod 21 is released, the tension spring 22 is reset, and the positioning rod 21 is pulled to re-insert the positioning hole 13, re-positioning the limit plate 19 and completing the installation and fixation of the grinding knife 11. This simplifies the replacement operation of the grinding knife 11. By pulling the positioning rod 21 and rotating the limit plate 19, the grinding knife 11 can be quickly disassembled and assembled without the need for complex tools and tedious steps, reducing maintenance time and labor costs, ensuring that the equipment can be quickly restored to an operational state, and improving equipment maintenance efficiency. At the same time, the fixing of the grinding knife 11 utilizes the elastic force of multiple tension springs 22, making the fixing method of the grinding knife 11 slightly elastic. When the kitchen waste contains hard materials such as sand, gravel, and glass, and is mixed with soft kitchen waste such as vegetable leaves, making it difficult to break, the knife will undergo a slight displacement due to the interference of these hard materials, preventing direct damage to the knife by hard forces.

[0039] The self-cleaning oil-water separation component is used to separate the oil-water mixture discharged through the organic matter recovery box 28 during the stir-frying process. Figures 16 to 18 The figure shows a specific embodiment of a self-cleaning oil-water separation component, which includes an oil-water heating separation box 40 fixedly connected to the inner wall of the box frame 1, and the oil-water heating separation box is connected to a grease discharge pipe 46, and also includes a purification box 47, and the purification box 47 is connected to the oil-water heating separation box 40. The outer wall of the purification box 47 is clamped with a pair of sealing side plates 49, and the pair of sealing side plates 49 are fixedly connected with evenly distributed card plates 50, and the adjacent card plates 50 are slidably connected with a honeycomb filter plate 51, and the outer wall of the purification box 47 is fixedly connected with a collection drainage pipe 48.

[0040] The oil-water liquid in the organic matter recovery tank 28 enters the oil-water heating and separation tank 40 through a pipeline (not shown in the figure). The oil-water heating and separation tank 40 heats the internal liquid and uses the density difference between oil and water to achieve oil and water separation. The separated oil and fat are located above the liquid and are discharged through the upper oil and fat discharge pipe 46 for recycling, while the water below the liquid enters the lower purification tank 47.

[0041] The outer wall of the purification box 47 is fixedly connected to a container drainage 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 impurities in the water. The purified water is finally discharged through the container drainage pipe 48. When the honeycomb filter plate 51 needs to be disassembled and replaced, it is only necessary to disassemble the sealing side plate 49 so that the honeycomb filter plate 51 can be pulled out of the card plate 50.

[0042] like Figure 12 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the solid-liquid separation box 24 with the organic matter discharge hole 38 is fixedly connected to the material guide box 31, and the bottom of the material guide box 31 is fixedly connected to the organic matter recovery box 28, and the organic matter recovery box 28 is connected to the oil-water heating separation box 40. The liquid separated by stir-frying in the solid-liquid separation box 24 flows into the material guide box 31 through the organic matter discharge hole 38, and the material guide box 31 guides the liquid to the organic matter recovery box 28 for temporary storage. The liquid after temporary storage then enters the oil-water heating separation box 40 through the connecting structure for subsequent treatment, which not only realizes the orderly collection and transportation of the liquid after solid-liquid separation, and ensures the continuity of the liquid processing link, but also because the stir-frying process in the present invention can adopt intermittent operation, the temporary storage function of the organic matter recovery box 28 prevents the liquid from directly entering the oil-water heating separation box 40 to cause impact, thereby improving the oil-water separation efficiency.

[0043] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the grinding chamber 5 is fixedly connected with a connecting pipe 23, and the connecting pipe 23 is connected to the solid-liquid separation box 24, and the ground particles enter the solid-liquid separation box 24 through the connecting pipe 23 for solid-liquid separation operation.

[0044] like Figure 11 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the solid-liquid separation box 24 is fixedly connected to a mounting bracket 25, the outer wall of the mounting bracket 25 is fixedly connected to a reduction motor 26, and the output end of the reduction motor 26 is fixedly connected to the drive rod 27, and the drive rod 27 is driven to rotate by the output end of the reduction motor 26.

[0045] like Figure 9 and Figure 10As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the grinding knife 11 is fixedly connected with a hexagonal limit block 17, and the hexagonal limit block 17 is slidably connected to the hexagonal limit hole 18. When the grinding knife 11 is installed, the hexagonal limit block 17 is embedded in the hexagonal limit hole 18, which limits the rotational deviation of the grinding knife 11 during operation, ensuring that it is precisely matched with the grinding teeth 8 for grinding. This structure not only ensures the stability of the grinding knife 11 during operation and improves the grinding effect, but also facilitates the rapid positioning and installation of the grinding knife 11 through sliding cooperation, and cooperates with the limit quick-release component to further simplify the disassembly and assembly process.

[0046] Specifically, when the food waste disposer is in use: after the food waste is put into the disposer, it first enters the feed hopper 4 and then falls into the grinding chamber 5. The drive motor 7 is started, and its output end drives the rotating column 9 to rotate, and the rotating column 9 then drives the turntable 10 to rotate, and the grinding knife 11 on the turntable 10 rotates accordingly. During the rotation process, the grinding knife 11 interacts 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 garbage are broken into smaller particles; the ground garbage particles enter the solid-liquid separation box 24 through the connecting pipe 23.

[0047] The driving rod 27 rotates under the drive of the output end of the reduction motor 26, and the stir-frying plate 35 rotates accordingly, continuously stir-frying the garbage in the solid-liquid separation box 24. During the stir-frying and drying process, the liquid components in the garbage flow out through the organic matter discharge holes 38 on the solid-liquid separation box 24 and enter the material guide box 31, and then are introduced into the organic matter recovery box 28 by the material guide box 31 for temporary storage. The oil and water can directly enter the oil-water heating separation box 40 through the filter screen in the organic matter recovery box 28 for oil-water separation.

[0048] As the driving rod 27 rotates, the material frying operation is performed. When the stir-frying plate rotates several times and reaches the set stir-frying time T, the material discharging operation is performed. The stir-frying plate continues to rotate. When the Hall effect sensor 34 detects that the magnetic block 33 has rotated to a preset angle A1, the electromagnetic head 37 is powered off 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 inclined discharge channel. At this time, the stir-frying plate 35 continues to rotate counterclockwise, pushing the solid waste remaining after solid-liquid separation to the discharge port and discharging it along the outer discharge plate 30; when the Hall effect sensor detects that the driving rod has rotated to a preset angle A2, the stir-frying plate 35 changes its rotation direction and starts to rotate clockwise. At the same time, the electromagnetic head 37 is energized to generate magnetism. During the rotation process, the stir-frying plate 35 contacts and lifts the inner discharge plate 36. 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 sealing state of the solid-liquid separation box 24 for the next round of garbage disposal.

[0049] The liquid in the organic matter recovery box 28 enters the oil-water heating separation box 40 through a pipeline. The oil-water heating separation box 40 heats the internal liquid and uses the density difference between oil and water to achieve oil and water separation. The separated oil is discharged through the oil discharge pipe 46 for recycling, and the separated water enters the purification box 47.

[0050] 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 container drainage pipe 48. When the honeycomb filter plate 51 needs to be disassembled and replaced, it is only necessary to disassemble the sealing side plate 49 so that the honeycomb filter plate 51 can be pulled out of the card plate 50.

[0051] Compared with the prior art, the present invention has the following beneficial effects: 1. The design of the limit quick-release assembly makes the replacement of the grinding blade simple and quick. When the grinding blade needs to be replaced, the limit on the connecting column can be quickly released by operating the limit quick-release assembly, so that the grinding blade can be easily removed and replaced, reducing maintenance time and cost, and ensuring the continuous and stable operation of the equipment. At the same time, the limit plate is positioned through the cooperation of multiple positioning holes and positioning rods, effectively preventing the block on the positioning plate from shaking or falling out of the slot, making the connection more stable and firm. 2. By setting up an angle detection device, the rotation angle of the driving rod can be accurately detected, and the automatic opening and closing of the inner discharge plate can be realized based on this. In conjunction with the stir-fry plate, the solid waste discharge process can be efficiently completed. The degree of automation is high, manual operation is reduced, and the problem of the existing Chinese food waste treatment process in which the discharge of solid waste mostly relies on manual operation or simple mechanical control, with a low degree of automation, is prone to incomplete discharge or jamming.

[0052] 3. The self-cleaning oil-water separation component can efficiently separate oil and water through heating and utilizing the density stratification of water and oil. The separated oil and grease can be recycled, which improves the utilization rate of resources. The separated water is discharged after purification, reducing pollution to the environment.

[0053] 4. By setting up the equipment to integrate multiple functions such as grinding, solid-liquid separation, oil-water separation, and purification, it can process food waste in one stop without the need for additional equipment, reducing the equipment's footprint and lowering the cost of use.

Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
