[0035] To make the purpose, technical solutions and advantages of the present invention more clear, the following will be combined with the attached Figure 1-12 The present invention is described in further detail.

[0036] Reference Figure 1 As shown, an intelligent device for processing kitchen waste includes a crushing device 1, a solid-liquid separation device 2, and an oil-water separation device 3;

[0037] Reference Figure 2 , Figure 3 As shown, the pulverizing device 1 includes a chassis 11, a first pulverizing blade roller 12, a second pulverizing blade roller 13, and a pulverizing drive device 14. The first and second pulverizing blade rollers 12 and 13 are arranged in parallel in the chassis 11. The first and second pulverizing blade rollers 12 and 13 are rotatably connected to the chassis 11 through bearings. The outer periphery of the first pulverizing blade roller 12 is respectively fixedly provided with a plurality of first large blades 121 and a plurality of first small blades 122, and the outer periphery of the second pulverizing blade roller 13 is respectively fixedly provided with a plurality of second large blades 131 and a plurality of second small blades 132. By arranging the large and small blades on the first and second pulverizing blade rollers 12 and 13, the contact area between the food waste and the blades is reduced, so that the force between the blade rollers is more uniform, and vibration impact caused during the shearing process of the blade rollers is avoided.

[0038] One end of the first pulverizing blade roller 12 extends outwards and is fixedly connected to the pulverizing drive device 14, and the other end extends outwards and is provided with a driving gear 15. One end of the second pulverizing blade roller 13 extends outwards and is provided with a driven gear 16 meshing with the driving gear 15. The pulverizing drive device 14 preferably adopts a reduction motor, and the first pulverizing blade roller 12 is driven to rotate by the pulverizing drive device 14, so that the driving gear 15 of the first pulverizing blade roller 12 is linked with the driven gear 16 to drive the second pulverizing blade roller 13 to rotate, so that the first and second pulverizing blade rollers 12 and 13 can rotate synchronously relative to each other, and the food waste is sheared and pulverized. The pulverized food waste is discharged from the discharge port of the chassis 11

[0039] Reference Figure 3 As shown, the first and second pulverizing blade rollers 12 and 13 are spaced apart and distributed along the axial direction, so that the first and second large blades 121 and 131 respectively form a plurality of gaps, the first small blades 122 of the first pulverizing blade roller 12 are respectively arranged in the gaps between the first large blades 121, and the second small blades 132 of the second pulverizing blade roller 13 are respectively arranged in the gaps between the second large blades 131.

[0040] The number of the first large blades 121 and the first small blades 122 of the first pulverizing blade roller 12 is equal to the number of the second large blades 131 and the second small blades 132 of the second pulverizing blade roller 13. The first large blades 121 of the first pulverizing blade roller 12 and the second large blades 131 of the second pulverizing blade roller 13 are arranged alternately. The outer peripheries of the first and second large blades 121, 131 and the first and second small blades 122, 132 are respectively provided with a plurality of arc-shaped protruding blade teeth along the circumferential direction. The first large blade 121 and the first small blade 122 of the first pulverizing blade roller 12 are respectively rotated relative to the second small blade 132 and the second large blade 131 of the second pulverizing blade roller 13, so that the large blades and the small blades are used to shear and crush the kitchen waste through the blade teeth, thereby enhancing the shearing effect and improving the work efficiency.

[0041] In order to improve the sealing performance of the chassis 11, the ends of the first and second pulverizing rollers 12 and 13 are provided with a first sealing sleeve, and the first sealing sleeve is arranged between the bearing and the side wall of the chassis 11, so as to prevent the food waste from entering the bearing during the pulverizing process and affecting the normal operation of the first and second pulverizing rollers 12 and 13. A sealing ring is provided between the upper opening of the chassis 11 and the hopper 111, and a sealing groove is provided at the upper opening of the chassis 11. The sealing ring is embedded in the sealing groove, so that when the food waste is poured into the hopper 111 and sent into the chassis 11 for pulverizing, the food waste is prevented from leaking out of the chassis 11, so that the workplace can be kept clean.

[0042] Reference Figure 1 As shown, the crushing device 1 is arranged above the solid-liquid separation device 2. When the food waste is poured into the hopper 111 and sent into the chassis 11 for shearing and crushing, the crushed food waste falls into the solid-liquid separation device 2 from the discharge port of the chassis 11.

[0043] Reference Figure 4 , Figure 5 As shown, the solid-liquid separation device 2 includes a shredder box 21 and a solid collecting barrel 22 and a liquid collecting tank body 23 arranged on one side of the shredder box 21. The liquid collecting tank body 23 is sleeved on the bottom of the solid collecting barrel 22. A rotating drive device 24 is arranged on the other side of the shredder box 21. A compression screw 211 is axially arranged in the shredder box 21. The end of the compression screw 211 is rotatably connected to the shredder box 21 through a bearing. A pushing spiral blade 212 is extended into the solid collecting barrel 22 on one side of the compression screw 211. The rotating drive device 24 preferably adopts a reduction motor. The rotating drive device 24 drives the compression screw 211 and the pushing spiral blade 212. A feed hopper 25 is arranged at the top feed port 1A of the shredder box 21. The upper opening of the feed hopper 25 is trumpet-shaped, which is conducive to the concentrated flow of food waste into the shredder box 21.

[0044] A knife edge 1B for cooperating with the compression screw 211 to cut off solid matter is provided on one side wall of the feed port 1A adjacent to the solid collecting barrel 22, and the top side of the knife edge 1B is fixedly provided on the inner side wall of the feed port 1A by welding.

[0045] One side of the solid collecting cylinder 22 is fixedly arranged on the surface of one side of the shredder box 21 by welding. The solid collecting cylinder 22 is communicated with the shredder box 21 to realize the circulation of food waste. The outer wall at the bottom of the solid collecting cylinder 22 has a plurality of small holes 221. The plurality of small holes 221 are used to filter and separate the solid and liquid of the food waste in the solid collecting cylinder 22 so that the liquid flows into the liquid collecting tank 23. The other side of the solid collecting cylinder 22 has a first row of fixed holes 222 to discharge the solid matter in the solid collecting cylinder 22.

[0046] The cross section of the liquid collecting tank body 23 is U-shaped. The inner top edge of the liquid collecting tank body 23 is fixed to the outer wall of the solid collecting barrel 22 by welding. One side of the liquid collecting tank body 23 is fixed to one side of the shredder box 21 by welding, so that the liquid collecting tank body 23 is sleeved on the bottom of the solid collecting barrel 22.

[0047] A gap is set between the inner bottom of the liquid collecting tank body 23 and the bottom of the solid collecting barrel 22 to form a drainage channel 231. A drainage port 232 is protruding from the outer wall of the liquid collecting tank body 23. The drainage port 232 is communicated with the drainage channel 231. A second solid drainage port 233 is set on the side of the liquid collecting tank body 23 adjacent to the first solid drainage port 222. When the liquid collecting tank body 23 is sleeved on the solid collecting barrel 22, the first and second solid drainage ports 222 and 233 are coaxial to transport the solids in the solid collecting barrel 22 to an external collection container, and the drainage port 232 is connected to an external pipeline to realize liquid discharge.

[0048] The end of the compression screw 211 has a second sealing sleeve, which is arranged between the bearing and the side wall of the chopping box to prevent the mixed liquid or solid matter in the chopping box 21 from leaking into the bearing and affecting the normal operation of the compression screw 211 and the pushing spiral blade.

[0049] Recombination Figure 6 As shown in the structural schematic diagram, the pushing spiral blade 212 in the embodiment of the present invention is a shaftless spiral blade, which is integrated with the spiral blade of the compression screw 211. The use of the shaftless spiral blade to convey solids has large torque and strong anti-winding performance, thereby avoiding blockage at the first and second rows of solid ports and ensuring the continuous operation of the device.

[0050] Reference Figure 4-Figure 6As shown, when working, the first and second pulverizing blade rollers 12 and 13 of the pulverizing device 1 shear the food waste into strip-shaped solids and then drop them into the feed hopper 25, thereby entering the shredding box 21. The rotary drive device 24 drives the compression screw 211 to rotate, and the strip-shaped solids in the food waste pass through the inner wall of the shredding box 21, the blade 1B cooperates with the compression screw 211 to cut off the solids, and then transport them to the solid collecting barrel 22. The pushing spiral blade 212 rotates to squeeze out the excess water in the solids and transports them to the first and second solid discharge ports 222 and 233 to be discharged outside the device. At the same time, the mixed liquid of the food waste is discharged into the liquid collecting tank body 23 through a plurality of small holes 221, and then flows to the liquid discharge port 232 to be discharged outside the device through the liquid discharge channel 231, thereby realizing solid-liquid separation.

[0051] Reference Figure 7 , Figure 8 As shown, the oil-water separation device 3 includes a box body 31, an oil inlet chamber 32, an oil-water flow stabilizing structure 33, an oil-water separation structure 34, and a drainage chamber 35, which are sequentially arranged in the box body 31 and are connected to each other. A delivery pipeline 321 is connected between the oil inlet chamber 32 and the drainage port 232 of the liquid collecting tank body 23. Figure 1 As shown, the oil-water separation structure 34 inputs the mixed liquid produced by the solid-liquid separation device 2 for oil-water separation treatment.

[0052] An oil drainage layer is provided between the oil-water flow stabilizing structure 33, the oil-water separation structure 34 and the top of the box body 31; the oil inlet chamber 32 and the oil-water flow stabilizing structure 33 are separated by a vertically arranged first partition plate 41; the drainage chamber 35 and the oil-water separation structure 34 are separated by a vertically arranged second partition plate 42; the bottom of the second partition plate 42 is communicated with the oil-water separation structure 34 and the drainage chamber 35; the oil drainage device 343 is fixedly arranged on one side of the second partition plate 42, at the end of the oil drainage layer.

[0053] Reference Figure 1 , Figure 7 , Fig. 9 As shown, a plurality of through holes 411 are arranged in a local array on the lower end surface of the first partition 41. The mixed liquid in the liquid collecting tank 23 is discharged into the oil inlet chamber 32 through the delivery pipe 321. The oil-water mixed liquid will form an unstable flow speed and direction due to pressure reasons. The plurality of through holes 411 can make the oil-water mixed liquid in the oil inlet chamber 32 flow to the oil-water steady flow structure 33 at a relatively stable flow speed and direction, thereby creating good conditions for oil-water separation. The plurality of through holes 411 also have a filtering effect, thereby preventing solids in the oil-water mixed liquid from flowing into the oil-water steady flow structure 33 and causing blockage.

[0054] Reference Figure 7 , Fig.10As shown, the oil-water flow stabilizing structure 33 includes a plurality of flow stabilizing components 331 and a constant temperature device 332 . The plurality of flow stabilizing components 331 are arranged side by side longitudinally. The plurality of flow stabilizing components 331 are composed of at least two layers of guide plates 333 which are stacked and fixedly connected. The constant temperature device 332 is fixedly arranged at the bottom of the plurality of flow stabilizing components 331 .

[0055] In this embodiment, the thermostat 332 is a heating tube, which is electrically connected to an external temperature control circuit. The thermostat 332 is preferably 5. The thermostat 332 can control the oil-water mixture flowing from the oil inlet chamber 32 into the oil-water steady flow structure 33 within a certain temperature range, effectively preventing the oil-water mixture from emulsifying and increasing the difficulty of subsequent oil-water separation. Usually, within the temperature range of the boiling point of water (the boiling point of water under a standard atmospheric pressure is 100°C), an increase in temperature will increase the density difference between the oil phase and the water phase and reduce the viscosity of the water, which is beneficial to oil-water separation. In this embodiment, the temperature is controlled at 30°C-40°C while comprehensively considering the maximization of economic benefits.

[0056] Reference Figure 7 As shown, the oil-water separation structure 34 includes a plurality of separation components 341, an air flotation separation device 342, and an oil discharge device 343. The overall structure of the plurality of separation components 341 is consistent with the plurality of flow stabilization components 331. The air flotation separation device 342 is relatively arranged at the bottom of the plurality of separation components 341, and the oil discharge device 343 is arranged between the plurality of separation components 341 and the drainage chamber 35.

[0057] The air flotation separation device 342 includes a bubble generating device 342-1 and an air pump. The bubble generating device 342-1 is connected to the air pump through a pipeline. The bubble generating device 342-1 is fixedly arranged at the bottom of the separation component 341, and the air pump is arranged outside the box 31. The bubble generator 342-1 generates bubbles to float. Since the density of oil is lower than that of water, the bubbles will combine with the oil with a closer density and gradually move upward to the separation component 341, thereby accelerating the separation of oil and water.

[0058] When the oil-water mixture passes through the oil-water stabilizing structure 33 and the oil-water separation structure 34 , the low-density oil floats to the oil drainage layer and flows into the oil drainage device 343 due to the effects of the oil-water stabilizing structure 33 and the oil-water separation structure 34 .

[0059] Reference Figure 7 , Fig.10 , Fig.11As shown, the guide plates 333 of several flow stabilizing components 331 are oleophilic and hydrophobic metal plates, which are composed of a plurality of inclined arrays of corrugations 333-1 inclined at 45 degrees, each corrugation 333-1 has a top angle of 90 degrees, and the channel 333-2 formed by two adjacent corrugations 333-1 is 90 degrees. Each layer of guide plates 333 is stacked, and the corrugations 333-1 between each layer of guide plates 333 are rotated 90 degrees. In this embodiment, two layers of guide plates 333 are arranged, and the two layers of guide plates 333 are stacked by welding. The plurality of separation components 341 are consistent with the plurality of flow stabilizing components 331.

[0060] Preferably, the guide plate 333 in this embodiment is made of 304 stainless steel.

[0061] Reference Fig.10 , Fig.11 As shown, the surface of the guide plate 333 is sprayed with an oleophilic and hydrophobic coating, which is nano liquid glass. The nano liquid glass is in liquid state before spraying, and dries and solidifies into a film attached to the surface of the guide plate 333 within a few minutes after spraying. The film layer has a thickness of 5-8um and a surface particle size of less than 20nm.

[0062] The plurality of flow stabilizing components 331 are of a stacked structure and the channels 333-2 formed therefrom can relatively stabilize the flow velocity and flow direction of the oil-water mixture. The nano-liquid glass sprayed on the surface of the guide plate 333 serves as an oleophilic and hydrophobic coating. It has good heat-insulating properties and can better prevent the oil-water mixture from directly contacting the surface of the guide plate 333 to cause heat loss, thereby reducing energy consumption. It can reduce the friction between the flowing oil-water mixture and the flow stabilizing component 331, and has a better drainage effect on the oil-water mixture, creating good conditions for subsequent oil-water separation.

[0063] When the oil-water mixture enters the oil-water stabilizing flow structure 33, the plurality of stabilizing flow components 331 have the characteristics of lipophilicity and hydrophobicity, and can separate a part of the oil in the oil-water mixture and float it to the oil drainage layer 311, while the remaining oil-water mixture flows along the channel 333-2 formed by the plurality of stabilizing flow components 331 to the oil-water separation structure 34 for further separation.

[0064] In the oil-water separation structure 34, the oil-water mixture undergoes adsorption, collision, fusion and other processes with the separation component 341 through its own gravity, flow action and the action of the air flotation separation device 342, so that the dispersed phase droplets grow into large droplets, and the large droplets are removed from the surface of the separation component 341, so that the light phase oil is separated and floats to the oil drainage layer, and the heavy phase water flows from the bottom to the drainage chamber 35 through the channel formed by the separation component 341. The nano liquid glass is used as an oleophilic and hydrophobic coating, and its surface particle size can be less than 20nm (the surface is smoother), so that the friction between the oil-water mixture and the surface of the separation component 341 is smaller, and its hydrophobic effect is more significant. The oil-water separation structure 34 of the present invention cooperates with the air flotation separation device 342 to further accelerate the separation effect of the oil-water mixture. Therefore, the practical oil-water separation device 3 is more energy-saving, has a higher separation efficiency, and a more significant separation effect. The separated water can meet the relevant national emission standards, and the separated oil has a high purity.

[0065] Reference Figure 7 As shown, a third partition plate 40 is vertically arranged between the oil-water flow stabilizing structure 33 and the oil-water separation structure 34, and the third partition plate 40 is longitudinally fixedly arranged in the middle of the box body 31, and one side of a plurality of flow stabilizing components 331 and a plurality of separation components 341 are respectively fixedly arranged on both sides of the third partition plate 40, and the other sides of a plurality of flow stabilizing components 331 and a plurality of separation components 341 are respectively longitudinally arranged with supporting partition plates 43, and the upper and lower ends of the supporting partition plates 43 are respectively aligned with the third partition plate 40.

[0066] Reference Figure 7 , Fig.12 As shown, the oil discharge device 343 includes a longitudinally arranged oil discharge chamber 343-1 and an oil discharge port 343-2 arranged at the bottom of the oil discharge chamber 343-1. A downwardly inclined guide strip 343-3 is arranged on the top of one side of the oil discharge chamber 343-1. The bottom of the guide strip 343-3 is arranged in contact with the top of the partition 43 on one side of the separation component 341, and the oil in the oil discharge layer on the top of the flow stabilizing component 331 and the separation component 341 can be drained into the oil discharge chamber 343-1. The guide strip 343-3 can prevent the oil in the oil discharge layer from flowing downward to the outside of the separation component 341. The oil discharge port 343-2 is connected by a pipe to transport the oil in the oil discharge chamber 343-1 to the collection barrel outside the box.
