A recovery pipe is provided at the upper end of the storage tank. The other end of the recovery pipe is located at the upper right end of the grease recovery tank.

[0004] The above-mentioned technical solutions are relatively simple in their filtration methods, which not only leads to poor filtration effect but also affects the filtration quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-stage refining and high-value utilization device for kitchen waste grease. Through multi-stage filtration, it solves the problem that a single filtration method not only leads to poor filtration effect but also affects filtration quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage refining and high-value utilization device for kitchen waste oil, comprising a processing unit; the processing unit consists of a processing box, a first filter mechanism, a second filter mechanism, a third filter mechanism, and a fourth filter mechanism. A bracket is installed at the bottom of the processing box. The first, second, third, and fourth filter mechanisms are installed sequentially from top to bottom inside the processing box. The first, second, third, and fourth filter mechanisms are located on the left side of the processing box and connected by a transmission mechanism. A power mechanism is installed on the left side of the first filter mechanism. The right side of the power mechanism is installed on the left side of the processing box via a mounting bracket. Inside the processing box, below the first, second, and third filter mechanisms, guide trays are installed. The bottom ends of the guide trays are respectively installed on the upper side of the second, third, and fourth filter mechanisms. A feeding mechanism is installed on the upper side of the processing box, and the bottom end of the feeding mechanism is connected to the first filter mechanism. A liquid collection mechanism is installed directly below the processing box, and a solid collection mechanism is installed on the right side of the processing box.

[0007] Furthermore, the liquid collection mechanism consists of a collection tray, a holding cabinet, a liquid collection bucket, and a cabinet door. The collection tray is installed at the bottom of the inside of the processing box, the holding cabinet is installed below the processing box, the cabinet door is rotatably installed at the front of the holding cabinet, and the liquid collection bucket is placed inside the holding cabinet directly below the collection tray.

[0008] Furthermore, the solid collection mechanism consists of an outlet pipe and a solid collection bucket. The outlet pipe is installed at the right end of the first, second, third, and fourth filtration mechanisms, and the solid collection bucket is placed directly below the outlet pipe.

[0009] Furthermore, the feeding mechanism consists of a hopper and a rotating cover plate. The left side of the rotating cover plate is rotatably mounted on the upper end of the hopper via a rotating shaft, and the bottom end of the hopper is mounted on the upper end of the processing box.

[0010] Furthermore, the first, second, third, and fourth filtration mechanisms are all composed of a feeding cylinder and an extrusion screw. The feeding cylinder is installed in the middle of the processing box, and the extrusion screw is rotatably installed inside the feeding cylinder. The feeding cylinder is provided with through holes all around its body.

[0011] Furthermore, the mesh size of the through holes around the upper feed cylinder of the first, second, third, and fourth filters increases sequentially.

[0012] Furthermore, the transmission mechanism consists of a synchronous belt and synchronous pulleys. The synchronous pulleys are installed on the outer section of the front end of the extrusion screw extending out of the processing box, and the synchronous belt is sleeved on the outside of the two synchronous pulleys of the guide wheel.

[0013] Furthermore, the power mechanism consists of an electric motor and a transmission, with the rear end of the transmission mounted on the front end of the processing box via a mounting bracket, and the rear end of the electric motor mounted on the front end of the transmission.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During this process, the grease and liquid separated by each filtration unit eventually converge at the bottom of the treatment tank and are collected by the liquid collection unit. Meanwhile, the solid impurities separated by each filtration unit are collected by the solid collection unit on the right side, achieving thorough separation and classification of solids and liquids and improving resource utilization.

[0016] 2. When the first, second, third, and fourth filtration mechanisms are working, the extrusion screw rotates inside the conveying cylinder under the drive of the power and transmission mechanisms. When kitchen waste enters the conveying cylinder, the rotating extrusion screw exerts a squeezing effect on the material, squeezing out the grease and liquid contained in the material. On the other hand, the screw structure pushes the material to the right side of the conveying cylinder. The squeezed-out grease and liquid permeate outward through the through holes set around the conveying cylinder, and then flow downward to the collection tray or enter the separation process of the next stage filtration mechanism. The solid impurities after being squeezed and dehydrated continue to move to the right side of the conveying cylinder under the push of the extrusion screw, and finally enter the solid collection bucket through the outlet pipe. The cooperation between the conveying cylinder and the extrusion screw realizes the integrated operation of material conveying, extrusion dehydration and solid-liquid separation, which plays a core role in the multi-stage refining of grease.

[0025] Example 1

[0026] like Figure 1-5As shown, this embodiment provides a multi-stage refining and high-value utilization device for kitchen waste oil, including a processing unit 1. The processing unit 1 consists of a processing tank 2, a first filter mechanism 23, a second filter mechanism 24, a third filter mechanism 25, and a fourth filter mechanism 26. A bracket 3 is installed at the bottom of the processing tank 2. The first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter mechanism 26 are installed sequentially from top to bottom inside the processing tank 2. The first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter mechanism 26 are located on the left side of the processing tank 2 and connected by a transmission mechanism 19. The first filtration mechanism 23 is located on the outside of the left side of the processing box 2 and a power mechanism 18 is installed. The right side of the power mechanism 18 is installed on the left side of the processing box 2 via a mounting bracket. Inside the processing box 2, below the first filtration mechanism 23, the second filtration mechanism 24, and the third filtration mechanism 25, a guide plate 22 is installed. The bottom of the guide plate 22 is installed on the upper side of the second filtration mechanism 24, the third filtration mechanism 25, and the fourth filtration mechanism 26, respectively. A feeding mechanism 8 is installed on the upper side of the processing box 2 and its bottom end is connected to the first filtration mechanism 23. A liquid collection mechanism 4 is installed directly below the processing box 2, and a solid collection mechanism 10 is installed on the right side of the processing box 2.

[0027] Preferably, the liquid collection mechanism 4 consists of a collection tray 5, a holding cabinet 6, a liquid collection bucket 7, and a cabinet door 14. The collection tray 5 is installed at the bottom inside the processing tank 2, the holding cabinet 6 is installed below the processing tank 2, and the cabinet door 14 is rotatably installed at the front of the holding cabinet 6. The liquid collection bucket 7 is placed inside the holding cabinet 6 directly below the collection tray 5. During the multi-stage filtration process, the grease liquid separated by each stage of the filtration mechanism drips downwards under the influence of gravity. Due to its installation position and structural design, the collection tray 5 at the bottom inside the processing tank 2 can receive these grease liquids from all directions, avoiding liquid residue or leakage. The collection tray 5 guides the collected grease liquid to the liquid collection bucket 7 directly below. The holding cabinet 6 provides a stable placement space for the liquid collection bucket 7 and also plays a protective role, preventing external contamination of the grease. When the grease in the liquid collection bucket 7 reaches a certain amount, the operator can open the cabinet door 14 to easily remove the liquid collection bucket 7 and carry out subsequent high-value processing and utilization of the collected refined grease, such as producing biodiesel, industrial grease, etc., to realize the recycling and reuse of grease resources.

[0028] Preferably, the solid collection mechanism 10 consists of an outlet pipe 11 and a solid collection bucket 12. The outlet pipe 11 is installed at the right end of the first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter mechanism 26. The solid collection bucket 12 is placed directly below the outlet pipe 11. As the first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter mechanism 26 operate, after each filter mechanism completes the grease separation of the corresponding stage, the remaining solid impurities will be pushed to the right end by the conveying action of the filter mechanism. At this time, the outlet pipe 11 installed at the right end of each filter mechanism plays a guiding role, accurately guiding the solid impurities separated by each stage into the solid collection bucket 12 directly below.

[0029] Preferably, the feeding mechanism 8 consists of a hopper 9 and a rotating cover 16. The left side of the rotating cover 16 is rotatably mounted on the upper end of the hopper 9 via a rotating shaft, and the bottom end of the hopper 9 is mounted on the upper end of the processing box 2. During feeding, the operator opens the rotating cover 16 by rotating it around the rotating shaft and pours the kitchen waste to be processed into the hopper 9. The structural design of the hopper 9 can guide the kitchen waste to flow smoothly downwards and avoid blockage during the feeding process. At the same time, the bottom end of the hopper 9 is directly connected to the first filter mechanism 23 at the upper end of the processing box 2, ensuring that the poured kitchen waste can quickly and accurately enter the first filter mechanism 23 to start the multi-stage refining and filtration process. During the operation of the equipment, closing the rotating cover 16 can prevent odor leakage inside the processing box 2, improve the operating environment, and prevent external debris from entering the processing box 2 and affecting the quality of oil refining.

[0030] Preferably, the first filtration mechanism 23, the second filtration mechanism 24, the third filtration mechanism 25, and the fourth filtration mechanism 26 are all composed of a feeding cylinder 28 and an extrusion screw 13. The feeding cylinder 28 is installed in the middle inside the processing box 2, and the extrusion screw 13 is rotatably installed inside the feeding cylinder 28. The feeding cylinder 28 is provided with through holes 27 all around its body. When the first filtration mechanism 23, the second filtration mechanism 24, the third filtration mechanism 25, and the fourth filtration mechanism are working, the extrusion screw 13 rotates inside the feeding cylinder 28 under the drive of the power mechanism 18 and the transmission mechanism 19. When the kitchen waste enters the feeding cylinder 28, the rotating extrusion screw 13 extrudes the material. The extrusion action squeezes out the oily liquid contained in the material. On the other hand, the spiral structure pushes the material to the right side of the conveying cylinder 28. The squeezed oily liquid permeates outward through the through holes 27 set around the conveying cylinder 28, and then flows downward to the collection tray 5 or enters the separation process of the next stage filtration mechanism. The solid impurities after being squeezed and dehydrated continue to move to the right side of the conveying cylinder 28 under the push of the extrusion screw 13, and finally enter the solid collection tank 12 through the outlet pipe 11. The cooperation between the conveying cylinder 28 and the extrusion screw 13 realizes the integrated operation of material conveying, extrusion dehydration and solid-liquid separation, which plays a core role in the multi-stage refining of oils.

[0031] Preferably, the mesh size of the through holes 27 around the upper conveying cylinder 28 of the first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter increases sequentially. The sequential increase in the mesh size of the through holes 27 in the conveying cylinder 28 means that the aperture of the through holes 27 gradually decreases. The first filter mechanism 23 has the smallest mesh size of 27 and a larger aperture, mainly used to filter large solid impurities in kitchen waste, achieving preliminary solid-liquid separation, allowing most of the grease and fine impurities to pass through the through holes 27. After entering the second filter mechanism 24, due to the increased mesh size of the through holes 27 and the smaller aperture, smaller solid particles in the material can be further filtered out, reducing the grease... The impurity content in the liquid is reduced; the third filtration mechanism 25 has a further increased mesh size of 27 through holes to continue filtering finer impurities and improve the purity of the oil; the fourth filtration mechanism 26 has the largest mesh size of 27 through holes and the smallest pore size, which can filter out tiny impurity particles in the material, achieving the ultimate fine filtration of the oil and obtaining refined oil with higher purity. This design of increasing mesh size of 27 through holes realizes graded filtration from coarse to fine, gradually removing impurities in the oil and ensuring that the finally collected oil meets the quality standards for high-value utilization. It also avoids impurities clogging the through holes 27 due to one-time fine filtration, improving filtration efficiency and equipment operation stability.

[0032] Preferably, the transmission mechanism 19 consists of a synchronous belt 21 and synchronous pulleys 20. The synchronous pulleys 20 are installed on the outer section of the front end of the extrusion screw 13 extending out of the processing box 2. The synchronous belt 21 is sleeved on the outside of the two synchronous pulleys 20. When the power mechanism 18 is running, it drives the extrusion screw 13 of the first filtration mechanism 23 to rotate. Since the extrusion screw 13 of the first filtration mechanism 23 is equipped with synchronous pulleys 20 on the outer section of the front end extending out of the processing box 2, and these synchronous pulleys 20 are connected to the synchronous pulleys 20 at the front end of the extrusion screw 13 of the second filtration mechanism 24, the third filtration mechanism 25, and the fourth filtration mechanism 26 through the synchronous belt 21, under the transmission action of the synchronous belt 21, the rotational power of the extrusion screw 13 of the first filtration mechanism 23 will be synchronously transmitted to the extrusion screws 13 of the second filtration mechanism 24, the third filtration mechanism 25, and the fourth filtration mechanism 26, so that the extrusion screws 13 of the four-stage filtration mechanisms maintain the same rotation direction and stable speed.

[0033] Preferably, the power mechanism 18 consists of an electric motor 17 and a gearbox 15. The rear end of the gearbox 15 is mounted on the front end of the processing box 2 via a mounting bracket, and the rear end of the electric motor 17 is mounted on the front end of the gearbox 15. When the equipment starts, the electric motor 17 starts to run as the power source, and the power generated is transmitted to the gearbox 15. The operator can adjust the output speed of the gearbox 15 according to the actual situation such as the type, humidity, and impurity content of the kitchen waste, so that the gearbox 15 transmits the appropriate speed to the extrusion screw 13 of the first filtration mechanism 23. When processing kitchen waste with high water content and few impurities, the speed can be appropriately increased to speed up the material conveying and filtration speed; when processing kitchen waste with low water content, many impurities, or relatively viscous, the speed can be reduced to ensure that the extrusion screw 13 has sufficient extrusion force to squeeze out the grease, while avoiding damage to the equipment due to excessive load.

[0034] Work steps

[0035] During operation, the power mechanism 18 synchronously drives the first filter mechanism 23, the second filter mechanism 24, the third filter mechanism 25, and the fourth filter mechanism 26 through the transmission mechanism 19, achieving efficient power transmission and coordinated operation. Food waste first enters the first filter mechanism 23 via the feeding mechanism 8 for preliminary solid-liquid separation and coarse filtration. Some of the separated liquid permeates downwards, while the incompletely filtered solid residue is conveyed to the right side by the first filter mechanism 23. Simultaneously, the guide plate 22 below the first filter mechanism 23 receives the insufficiently filtered material and precisely guides it to the second filter mechanism 24. Subsequently, the second filter mechanism 24 performs secondary refining filtration on the material, further separating... Similarly, after separating grease and solid impurities, the remaining material is guided to the third filtration mechanism 25 by the guide tray 22 below. After the third filtration mechanism 25 completes three filtrations, the material is then guided to the fourth filtration mechanism 26 by the guide tray 22 for final fine filtration. Through four-stage progressive filtration from top to bottom, the grease in the kitchen waste is gradually purified, improving the purity of the grease and meeting the needs of high-value utilization. During this process, the grease liquid separated by each filtration mechanism eventually converges at the bottom of the treatment tank 2 and is collected by the liquid collection mechanism 4. The solid impurities separated by each filtration mechanism are collected by the solid collection mechanism 10 on the right side, achieving thorough separation and classification of solid and liquid, and improving resource utilization.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
