Description
Technical Field
[0001] This invention relates to the field of kitchen waste technology, specifically to kitchen waste recycling equipment based on a multi-stage processing device. Background Technology
[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and catering services provided by institutions. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc., as well as some plastic, disposable bags, ironware, metal cans, etc. used in the kitchen.
[0003] With proper handling and processing, it can be transformed into new resources. Its high organic content makes it suitable as fertilizer and feed after strict processing. It can also produce biogas for use as fuel or for power generation. The oil portion can be used to prepare biofuels.
[0004] However, existing food waste treatment devices have two main drawbacks: firstly, due to the diverse types of food waste, solid-liquid separation cannot be achieved through a single compression method; secondly, everyday waste, especially metals such as iron fragments and ironware, is mixed in with food waste and is difficult to separate, posing challenges to subsequent processing. Summary of the Invention
[0005] The purpose of this invention is to provide a kitchen waste recycling device based on a multi-stage processing unit. Through the interaction of the first and second arc plates, the kitchen waste inside can be continuously stirred and agitated. The waste is continuously compressed in the dynamic compression channel formed by the first and second arc plates, which can continuously squeeze out the water in the waste and discharge it through the wastewater spiral conveying channel, thereby achieving solid-liquid pre-separation. Furthermore, since the first and second arc plates are made of electromagnets, the waste can be adsorbed by the continuous interlocking and turning of the first and second arc plates, thereby achieving the separation of metal from waste.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a kitchen waste recycling device based on a multi-stage processing unit, comprising: a base, on which a storage box is disposed, and a waste disposal bin disposed on the storage box, wherein a stirring and compression mechanism is disposed at the lower part of the waste disposal bin for continuously stirring and compressing the kitchen waste; and a waste residue spiral conveying channel and a wastewater spiral conveying channel connected to the bottom of the waste disposal bin; the waste disposal bin includes a feeding bin, and rectangular cavities and semi-circular cavities formed within and connected to each other in the feeding bin; the stirring and compression mechanism includes a...

A second arc plate is installed on the other end of the feeding hopper and is eccentrically positioned with respect to the circular plate.

[0010] Preferably, the planetary gear meshing mechanism includes a vertical plate fixed to the side wall of the feed hopper, and a mounting plate fixed to the lower part of the vertical plate. A rotatable central gear is mounted at the center of the mounting plate. The central gear passes through the mounting plate and is connected to a second mounting tube.

The inner side of the moving arc plate has a raised strip, the inner cylinder has water permeable holes, and a limiting block is set on the inner side of the tank. The limiting block is shaped like a knife corner and is located at the outlet chamber. When the inner cylinder drives the moving arc plate to rotate at high speed, the moving arc plate retracts near the limiting block and fits against the outer wall of the inner cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] 1. This invention utilizes the interaction between the first and second arc plates to continuously stir and agitate the internal kitchen waste. The waste is continuously compressed in the dynamic compression channel formed by the first and second arc plates, which squeezes out the water and discharges it through the wastewater spiral conveying channel, achieving solid-liquid pre-separation. Furthermore, the first and second arc plates are made of electromagnets, and through the continuous interlocking and turning of the waste by the first and second arc plates, residual metals in the waste can be adsorbed, achieving separation of metals from waste.
[0018] 2. As another embodiment of the present invention, the provided waste residue spiral conveying channel is used to perform secondary treatment on the pre-treated kitchen waste in the embodiment. The large pitch and low speed of the first spiral blade push the larger plastic to move outward, while the small pitch and high speed of the second spiral blade gather the fine kitchen waste towards the center. The plastic is thrown to the outer edge because of its large volume and light weight, while the kitchen waste sinks to the inner side because of its high density.
[0019] 3. Through the setting of the processing tank assembly, when it works with the waste residue screw conveyor channel, the waste residue is mainly small, sticky kitchen waste. At the moment when the end of the transmission arc plate leaves the limit block, the centrifugal force causes the transmission arc plate to release and open instantly, which can impact and slap the incoming kitchen waste to the blade area for further crushing. As the transmission arc plate continues to rotate, it can push the waste on the back side of the transmission arc plate towards the limit block and enter the next processing tank assembly. At the same time, under the action of the limit block, the transmission arc plate gradually compresses and closes after approaching the limit block, completing the squeezing of the waste placed on the inside of the convex strip and inner cylinder, and completing the secondary solid-liquid separation.
[0020] 4. By further setting a valve plate on the transmission arc plate, when it interacts with the wastewater spiral conveying channel, it can act as a static filtration device. When the wastewater enters from the inlet chamber and passes through the inside of the tank, it acts on the area where the installation groove is located, which has dense filter holes, and impacts the valve plate where the transmission arc plate is located to open it. At this time, several transmission arc plates form several interception filter layers, which can filter the wastewater layer by layer. Attached Figure Description

[0042] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.
[0043] Example 1
[0044] Please see Figures 1 to 13 The present invention preferably provides a technical solution: a kitchen waste recycling device based on a multi-stage processing unit, comprising: a base 111, a storage box 211 disposed on the base 111, and a waste disposal bin disposed on the storage box 211, wherein a stirring and compression mechanism is disposed at the lower part of the waste disposal bin for continuously stirring and compressing the kitchen waste; and a waste residue spiral conveying channel and a wastewater spiral conveying channel connected to the bottom of the waste disposal bin; the waste disposal bin includes a feeding bin 511, and rectangular cavities 5111 and semi-circular cavities 5112 disposed within the feeding bin 511 and connected to each other, the stirring and compression mechanism comprising a device installed in the feeding bin 511... The hopper 511 has a rotatable circular plate 512 at one end, on which a first arc plate assembly is provided. The first arc plate can run along the inner wall of the semi-circular cavity 5112. A second arc plate is installed at the other end of the hopper 511 and is eccentrically positioned with respect to the circular plate 512. The first arc plate and the second arc plate interact to form a dynamic compression channel for the waste. When the circular plate 512 rotates, it drives the first arc plate to move in a circular motion and forces the second arc plate to rotate intermittently, thereby squeezing the waste in the dynamic compression channel. The first arc plate and the second arc plate are made of electromagnet material and are used to adsorb residual metals in the waste when inserting and turning the waste.
[0045] In this application, a tumbling and compressing mechanism is installed at the bottom of the waste disposal compartment, such as... Figure 1 , 3As shown in Figures 7 and 8, the interaction between the first and second arc plates allows for continuous agitation and stirring of the internal kitchen waste. The waste is continuously compressed, squeezed out, and extended within the dynamic compression channel formed by the first and second arc plates. The implementation methods include:
[0046] The first method: When the waste residue screw conveyor channel and the wastewater screw conveyor channel are combined with the stirring and compressing mechanism, the wastewater screw conveyor channel can be opened first. Through the pretreatment of the stirring and compressing mechanism, the water in the waste can be continuously squeezed and discharged through the wastewater screw conveyor channel to achieve solid-liquid pre-separation.
[0047] Another method involves using electromagnets for the first and second arc plates. As the first and second arc plates continuously interweave and flip the garbage, they can adsorb residual metals within the garbage, thus separating the metals from the garbage.
[0048] Example 2
[0049] In another embodiment of the present invention, the first arc plate includes a first plate 5121, a through hole 5122 formed on the first plate 5121, and a shovel portion 5123 provided in the forward direction of the through hole 5122; the second arc plate includes a second plate 5131, and limiting grooves 5132 formed on both sides of the second plate 5131. The second plate 5131 is eccentrically arranged relative to the circular plate 512 and has a mounting shaft 5135 rotatably mounted at its center. The mounting shaft 5135 extends to the side wall of the circular plate 512 and is fixedly connected thereto, and two limiting posts 5133 are fixed on the circular plate 512. The two limiting posts 5133 can sequentially enter the limiting grooves 5132 to limit the rotation of the second plate 5131; it also includes a third motor 514 fixed at the end of the feed bin 511. The output shaft of the third motor 514 extends into the feed bin 511 and is fixed to the center of the circular plate 512 to drive its rotation.
[0050] In this embodiment, a structure for a first arc plate and a second arc plate is provided, such as... Figure 7 and 8 As shown, the through hole 5122 acts on the edge of the circular plate 512 and adheres to the inner wall of the semi-circular cavity 5112. When the circular plate 512 drives the through hole 5122 to rotate, the shovel part 5123 can continuously scoop up kitchen waste. When the limiting post 5133 on the circular plate 512 interacts with the limiting groove 5132 on the second plate 5131, since the second plate 5131 is eccentrically set relative to the circular plate 512, it can be moved to rotate around the mounting shaft 5135, thereby realizing the compression transformation of the dynamic compression channel for waste formed by the first arc plate and the second arc plate. Figure 8 The compressed wastewater is squeezed out through the through hole 5122, and with the brush 5134 in place, the first arc plate and the second arc plate interact to achieve the cleaning of the through hole 5122 by the brush 5134.
[0051] Example 3
[0052] In another embodiment of the present invention, the wastewater spiral conveying channel includes a second conveying pipe 411, and a first channel 413 connecting the feed bin 511 and the second conveying pipe 411. The first channel 413 is provided with a first solenoid valve for controlling the opening and closing of the first channel 413, and a filter screen provided at the top of the first channel 413; and a first motor 412 provided at the end of the second conveying pipe 411. The output shaft of the first motor 412 extends into the second conveying pipe 411 and is provided with a spiral conveying rod. The other end of the second conveying pipe 411 is provided with a second connecting pipe 4111.
[0053] The wastewater spiral conveying channel is pre-treated based on the aforementioned tumbling and compression mechanism. By selectively opening its channel first, the continuously compressed wastewater can be discharged.
[0054] Example 4
[0055] In another embodiment of the present invention, the waste residue spiral conveying channel includes a first conveying pipe 311 and a first spiral blade 312 connecting the feed hopper 511 and the first conveying pipe 311. A second solenoid valve is provided inside the first spiral blade 312 for controlling the opening and closing of the first spiral blade 312. A double spiral separation assembly is provided inside the first conveying pipe 311 for separating plastics from kitchen waste. The double spiral separation assembly includes an inner spiral blade and an outer spiral blade surrounding the inner spiral blade. The inner spiral blade includes a central rod 3132 and a second spiral blade 313 disposed on the central rod 3132. The outer spiral blade includes a second mounting pipe 315 and a second spiral blade 313 fixed on the second mounting pipe 315. A first helical blade 312 is wrapped around the outside of a second helical blade 313 and connected to a first mounting pipe 314 at the end away from the second mounting pipe 315. A first discharge channel 3112 is provided at the lower part of a first conveying pipe 311 near the first mounting pipe 314. The bottom of the first discharge channel 3112 is connected to a storage box 211 for discharging light and fluffy plastic. A first connecting pipe 3111 is provided at the end of the first mounting pipe 314 away from the first conveying pipe 311. The inner helical blade extends into the first connecting pipe 3111 for discharging kitchen waste with high moisture content and high density. A planetary gear meshing mechanism is provided on the feeding bin 511 for driving the inner and outer helical blades to rotate at different speeds.
[0056] Furthermore, the planetary gear meshing mechanism includes a vertical plate 820 fixed to the side wall of the feed bin 511, and a mounting plate 819 fixed to the lower part of the vertical plate 820. A rotatable central gear 816 is mounted at the center of the mounting plate 819. The central gear 816 passes through the mounting plate 819 and is connected to the second mounting tube 315. An internal gear ring 818 rotates on the mounting plate 819. A plurality of planetary gears 817 are arranged circumferentially between the internal gear ring 818 and the central gear 816. A second transmission wheel 814 extends from the internal gear ring 818. The central rod 3132 where the internal helical blade is located passes through the central gear 816 and is fixedly connected to the center of the second transmission wheel 814. A mounting component 812 is fixed on the feed bin 511. A fourth motor 813 is mounted on the mounting component 812. The output shaft of the fourth motor 813 is fixed to a second drive wheel 811. A second belt 815 is connected between the second drive wheel 811 and the second transmission wheel 814.
[0057] Furthermore, the second helical blade 313 has a small pitch design, while the first helical blade 312 has a large pitch and uses a ceramic coating, which can reduce plastic adhesion.
[0058] In this embodiment, the provided waste residue spiral conveying channel is used for secondary treatment of the pretreated kitchen waste from Embodiment 1. The designed waste residue spiral conveying channel employs a double-helix blade structure with inner and outer spiral blades, such as... Figure 3 , 4 As shown in Figures 5 and 6, specifically, the inner second helical blade 313 has a small pitch design, while the outer first helical blade 312 has a large pitch and is coated with ceramic. Under the action of the planetary gear meshing mechanism, when the fourth motor 813 is working, the second transmission wheel 814 can be driven to rotate under the transmission action of the second belt 815. The second transmission wheel 814 is connected to the central rod 3132 and is used to drive the inner second helical blade 313 to rotate at high speed. At the same time, the internal gear ring 818 where the second transmission wheel 814 is located rotates, under the action of the planetary gear 817. The first spiral blade 312, located in the second mounting pipe 315 where the central gear 816 is located, rotates at a low speed. The large pitch and low speed of the first spiral blade 312 pushes larger-sized plastics outwards, while the small pitch and high speed of the second spiral blade 313 gathers fine kitchen waste towards the center. Due to density differences—kitchen waste has a high water content and high density, while plastic is light and fluffy—layering is achieved through the spiral gap and speed difference. The spiral rotation generates centrifugal force; the plastic, due to its large volume and light weight, is thrown to the outer edge, while the kitchen waste, due to its high density, sinks to the inner side. Figure 1 As shown, the outer plastic enters the storage box 211 through the first discharge channel 3112 for collection, while the fine kitchen waste on the inner side is discharged into the next stage of processing through the first connecting pipe 3111.
[0059] Example 5
[0060] As another embodiment of the present invention, based on the inner helical blade and the outer helical blade, the inner side of the first helical blade 312 and the outer wall of the second helical blade 313 are respectively provided with a first serration 3121 and a second serration 3131 for cutting the wound plastic.
[0061] Based on Example 4, such as Figure 5 , 6 As shown, by further setting the first saw tooth 3121 and the second saw tooth 3131, in conjunction with their own spiral motion, long and tangled plastic can be cut.
[0062] Example 6
[0063] In another embodiment of the present invention, a waste fine treatment component is also provided on the base 111 for receiving and processing the products of the waste residue spiral conveyor channel and the wastewater spiral conveyor channel; the waste fine treatment component includes several sets of treatment tank assemblies connected end to end, each set of treatment tank assemblies includes a tank body 611, and an inlet chamber 616 and an outlet chamber 617 respectively connected to the upper and lower parts of the tank body 611. The first inlet chamber 616 is connected to the end of the second connecting pipe 4111 and the first connecting pipe 3111, and an inner cylinder 613 rotatably installed inside the tank body 611. Three first adapter seats 614 are provided around the inner cylinder 613, and each of the three first adapter seats 614 is mounted with a deflectable pin. The rotating transmission arc plate 612 has a buffer pad 6122 at the end away from the first adapter seat 614, and a protrusion 6121 on the inner side of the transmission arc plate 612. The inner cylinder 613 has a water permeable hole 6131 and a limiting block 615 on the inner side of the tank body 611. The limiting block 615 is shaped like a knife corner and is located at the outlet chamber 617. When the inner cylinder 613 drives the transmission arc plate 612 to rotate at high speed, the transmission arc plate 612 retracts and fits against the outer wall of the inner cylinder 613 near the limiting block 615. When it detaches from the limiting block 615, the limiting block 615 opens quickly under centrifugal force and knocks the kitchen waste into the knife edge area 630 for crushing.
[0064] When used as a waste slag screw conveyor, the waste slag mainly consists of small, adhered kitchen waste. The inner cylinder 613 drives three circumferentially rotating transmission arc plates 612 to rotate at high speed, in conjunction with the action of the limiting block 615. Figure 11As shown, the inner cylinder 613 rotates counterclockwise at high speed. At the instant the end of the transmission arc plate 612 leaves the limiting block 615, the centrifugal force causes the transmission arc plate 612 to release and open instantly, which can impact and slap the incoming kitchen waste into the blade area 630 for further crushing. As the transmission arc plate 612 continues to rotate, the waste on the back side of the transmission arc plate 612 can continue to be pushed towards the limiting block 615 and enter the next processing tank assembly. At the same time, under the action of the limiting block 615, the transmission arc plate 612 gradually compresses and closes after approaching the limiting block 615, thus squeezing the waste placed between the protrusion 6121 and the inner cylinder 613, and realizing secondary discharge of water at the squeezing position.
[0065] Example 7
[0066] In another embodiment of the present invention, each transmission arc plate 612 is provided with an installation groove 913 on its outer wall. The area where the installation groove 913 is located is provided with dense filter holes. A second adapter seat 912 is provided at the end of the installation groove 913 near the inner cylinder 613. An openable valve plate 911 is installed on the second adapter seat 912. A torsion spring is connected between the valve plate 911 and the second adapter seat 912.
[0067] In this embodiment, by further configuring the valve plate 911, when interacting with the wastewater spiral conveying channel, such as... Figure 10 and 11 As shown, when it can be used as a static filtration device, wastewater enters from the inlet chamber 616 and passes through the inside of the tank 611. The dense filter holes in the area where the mounting groove 913 is located act on the valve plate 911 where the transmission arc plate 612 is located, causing it to open.
