[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 11As shown, a kitchen waste solid-liquid impurity separator of the present invention includes: a box body 10, an oil-water collecting box 20, an upper sinking electrode 21, a lower sinking electrode 22, and an oil-liquid collecting piece. The oil-water collecting box 20 is arranged on the bottom wall inside the box body 10. The oil-water collecting box 20 is used to hold oil and water separated from solids. The oil-liquid collecting piece is lifted and lowered in the oil-water collecting box 20. The upper sinking electrode 21 and the lower sinking electrode 22 are lifted and lowered on the oil-water collecting box 20. The oil-liquid collecting piece is lifted and lowered inside the oil-water collecting box 20, and the oil-liquid collecting piece can adjust the collection opening according to the thickness of the oil layer, and the oil-liquid collecting piece can prevent the newly separated liquid from disturbing the stratified oil.

[0031] During separation, the upper sinking electrode 21 and the lower sinking electrode 22 move in opposite directions, so that when the upper sinking electrode 21 moves from oil to water, the lower sinking electrode 22 moves from water to oil. Since water is a conductor and has stronger conductivity when it contains impurities, and oil is an insulator, the dielectric constants of the two are very different. Therefore, when the upper sinking electrode 21 moves from oil to water, the two electrodes are inserted into the liquid. When the electrodes cross the oil-water interface, the conductivity will suddenly change. Therefore, the upper sinking electrode 21 and the lower sinking electrode 22 can accurately determine the oil-water interface. At the same time, the oil thickness can be judged by the depth of the upper sinking electrode 21. The oil collection component can adjust the size of the collection port according to the thickness of the oil layer, thereby improving the collection efficiency and effect. The oil collection component can buffer the newly separated liquid, which can improve the separation efficiency while ensuring the stability of the stratification system.

[0032] like Figures 1 to 4 As shown, a waste trough 11 is provided on the top of the box body 10. The waste trough 11 is square and has an upward opening. The waste trough 11 is used to temporarily store kitchen waste. A crushing assembly 12 is provided inside the box body 10. The crushing assembly 12 is located below the waste trough 11 and is used to crush the kitchen waste contained in the waste trough 11 so as to separate the solid and liquid by subsequent extrusion. A first extrusion sleeve 14 and a second extrusion sleeve 13 are provided inside the box body 10, and a protective box is provided below the crushing assembly 12 and is connected to the first extrusion sleeve 14 so that the crushed kitchen waste can pass through the protective The box enters the interior of the first extrusion sleeve 14, the diameter of the second extrusion sleeve 13 is larger than that of the first extrusion sleeve 14, and the second extrusion sleeve 13 is sleeved on the outer circumference of the first extrusion sleeve 14, and the axes of the two coincide, the second extrusion sleeve 13 and the first extrusion sleeve 14 are arranged in an inclined shape inside the box body 10, so that the separated liquid can flow downward by gravity, and a conveying auger 16 is provided inside the first extrusion sleeve 14, and the second extrusion sleeve 13 is sleeved on one end of the first extrusion sleeve 14 and a drive motor 17 is provided, and the output end of the drive motor 17 is transmission-connected to the conveying auger 16.

[0033] An elastic sealing member is provided at the end of the first extrusion sleeve 14 away from the drive motor 17, and a filter hole 15 is circumferentially opened on the outer peripheral surface of the first extrusion sleeve 14 away from the drive motor 17. The elastic sealing member is used to intercept and squeeze kitchen waste. A guide tube 19 is provided on the outer peripheral surface of the second extrusion sleeve 13.

[0034] When solid-liquid separation is performed, after the kitchen waste enters the waste trough 11, the crushing assembly 12 crushes large particles or flexible waste, and the crushed waste enters the first extrusion sleeve 14 through the protective box, and then the driving motor 17 drives the conveying auger 16 to rotate. The rotation of the conveying auger 16 drives the crushed kitchen waste to move toward the elastic sealing part. As the conveying auger 16 continues to convey, the waste continues to accumulate at the elastic sealing part, and pressure is formed to separate the solid and liquid. The separated liquid will pass through the filter hole 15 into the second extrusion sleeve 13. Since the second extrusion sleeve 13 is also in an inclined state, the separated liquid flows from the extrusion end toward the drive motor 17, and enters the oil-water collection box 20 through the guide tube 19.

[0035] like Figures 4 to 11 As shown, support plates are provided on the opposite inner walls of the oil-water collection box 20, a motor 24 is provided on the top of one of the support plates, a gear 25 is provided at the output end of the motor 24, an upper water-sinking electrode 21 is provided on the support plate for lifting, the upper end of the upper water-sinking electrode 21 is a square rod, and a plurality of electrode needles 29 are provided at the lower end, and the electrode needles 29 are evenly spaced as shown in FIG. Figure 9 As shown, one side outer wall of the upper water-sinking electrode 21 is provided with teeth 23, which are engaged with the gear 25. The lower water-sinking electrode 22 is raised and lowered inside the oil-water collecting box 20, and a plurality of electrode needles 29 are also provided on the top of the lower water-sinking electrode 22. In this application, the lower water-sinking electrode 22 is driven to rise and fall by a telescopic component, and the upper water-sinking electrode 21 and the lower water-sinking electrode 22 are located at different positions inside the oil-water collecting box 20 to improve the measurement accuracy of the two and ensure the accuracy during separation and collection. A signal collection module 27 is provided on the support plate, and the signal collection module 27 can collect, integrate and feedback data.

[0036] When determining the oil-water interface, the telescopic assembly drives the lower submersible electrode 22 upward, moving it from the water into the oil. A sudden change in conductivity of 3-6 orders of magnitude signals the interface identification. Simultaneously, the motor 24 drives the gear 25 to rotate. Because the teeth 23 mesh with the gear 25, the gear 25 and the teeth 23 cooperate to drive the upper submersible electrode 21 downward, inserting it into the oil and moving it toward the interface. Similarly, when the bottom of the upper submersible electrode 21 crosses the interface, the conductivity also changes suddenly. The interface is then accurately determined using the two submersible electrodes. The oil layer thickness is then identified by the difference in the dielectric constant between the air and oil conductivity. When the electrode is inserted from the air into the oil layer, the electrical parameter undergoes a first step change. After contacting the oil layer, the conductivity increases slightly, but remains significantly higher than that of air, with the dielectric constant jumping to 2-3. When the electrode is inserted from the oil layer into the water layer, the electrical parameter undergoes a second step change, with a magnitude far greater than that of the air and oil interfaces. After the interface is determined, the thickness can be determined by reading the scale of the upper submersible electrode 21.

[0037] Using the synchronous measurement results of multiple electrode needles 29, the "majority voting method" is used to eliminate the misjudgment of a single electrode needle 29, such as the interference of local bubbles and impurities. Assuming that the total number of electrode needles 29 of the upper submerged electrode 21 and the lower submerged electrode 22 is n, when the conductivity mutation threshold is met, Number of electrode needles 29 When , it is determined that the whole crosses the oil-water interface, where For the The real-time conductivity of the electrode needle 29.

[0038] The upper submerged electrode 21 is calculated based on the interface depth of the multi-electrode needle 29, wherein the interface depth of the single needle is: The interface depth of the root sinking electrode needle 29 is: in, For the The distance from the upper electrode needle 29 of the upper submerged electrode 21 to the conductivity mutation point, outlier removal: remove Outliers that deviate from the mean by more than 2 times the standard deviation, extreme values ​​caused by local disturbances, retain valid data sets ; Finally, after data fusion, the interface depth measured by the submerged electrode 21 is: The calculation of the interface depth of the sinking water electrode 22 based on the multi-electrode needle 29 is the same as the above steps. , I will not go into details here.

[0039] Combining the multi-needle fusion results of the upward and downward double-electrode groups, the system error is further reduced by weighted averaging to meet the following calculation formula: in, is the final determined depth of the oil-water interface, is the depth of the oil-water interface measured by the upper submerged electrode 21, It is the depth of the oil-water interface measured by the sinking water electrode 22.

[0040] At this time, the signal collection module 27 can feed back the calculated and processed information to the control module, and the control module can accurately calculate the stratification interface and thickness based on the information, so as to control the size of the collection port of the oil collection component and the speed of the oil collection component's descent and collection according to the thickness of the oil layer, so as to improve the oil collection efficiency while ensuring the collection effect. When the oil layer thickness becomes thinner, the control module controls the collection port of the oil collection component to become smaller. When the oil layer thickness reaches the set threshold, the control module controls the oil collection component to change the oil layer thickness, and quickly and accurately extract the oil layer again.

[0041] like Figures 5 to 11 As shown, the oil collection member includes: an annular collection shell 40, a rotating ring 42, a connecting piece 43, a rotating shaft 44, a flip leaf 41, and a fixed cylinder 46. The annular collection shell 40 is lifted and set inside the oil and water collection box 20. The fixed cylinder 46 is set at the center of the annular collection shell 40, and the fixed cylinder 46 coincides with the axis of the annular collection shell 40, and the two are fixedly connected. The outer circumferential surface of the fixed cylinder 46 and the inner annular surface of the annular collection shell 40 are provided with a plurality of flip leaves 41, and the plurality of flip leaves 41 are uniformly distributed in the circumferential direction. The multiple flip leaves 41 are arranged at intervals, and when they are flipped to a horizontal state, they can form an annular sealing flat plate to prevent the odor from floating upward. A conical funnel is provided at the bottom of the annular collection shell 40, and a telescopic tube 47 is provided at the bottom of the conical funnel. The telescopic tube 47 can be extended and retracted when the oil collection piece is raised or lowered. An inclined tube 48 is provided on the inner wall of one side of the oil-water collection box 20, and one end of the inclined tube 48 is connected to the telescopic tube 47. A suction pump 70 is provided on the outer wall of the annular collection shell 40, and a collection hole 60 is provided at the center position of the fixed cylinder 46.

[0042] The annular collecting shell 40 is composed of two annular cylinders of different diameters with an annular interlayer between the two. A rotating shaft 44 is fixedly arranged on the flip leaf 41. The two ends of the rotating shaft 44 are rotatably connected to the annular collecting shell 40 and the fixed cylinder 46 respectively, and the rotating shaft 44 extends to the interlayer position of the annular collecting shell 40. The connecting piece 43 is fixedly arranged at the end extending from the rotating shaft 44. The rotating ring 42 is rotatably arranged in the annular interlayer of the annular collecting shell 40, and the rotating ring 42 is rotatably connected to the connecting piece 43, so that the rotating ring 42 controls the flip leaf 41 to rotate through the connecting piece 43 to change the size of the collection port of the oil collecting piece.

[0043] After the signal collection module 27 determines the stratified interface and thickness, when the stratified oil needs to be collected, the control module controls the rotation of the rotating ring 42. The rotation of the rotating ring 42 drives the connecting piece 43 to rotate with the connection point of the rotating shaft 44 as the center, thereby driving the rotating shaft 44 to rotate. The rotation of the rotating shaft 44 drives the flip leaf 41 to rotate, so that the multiple flip leaves 41 are in the shape of a turbofan. When the oil collection part moves downward as a whole, the oil can quickly enter the inner ring surface of the annular collection shell 40, and the oil flows downward through the gaps between the flip leaves 41 to the conical funnel, and The oil and water collecting box 20 is discharged through the telescopic tube 47 and the inclined tube 48. When the oil layer reaches the preset threshold, the control module controls the rotating ring 42 to reset and rotate, so that the multiple flip leaves 41 rotate to a horizontal state and are sealed. Then the oil collecting part moves downward to collect the thin oil layer to the top of the flip leaf 41, causing the oil surface to shrink and the thickness to increase, and the oil is accurately layered and separated again. The suction pump 70 sucks the water inside the oil and water collecting box 20 to the top of the flip leaf 41 to raise the liquid level. The oil enters the telescopic tube 47 and the inclined tube 48 through the collection hole 60 and is finally discharged.

[0044] like Figures 1 to 4 As shown, the outer circumference of the annular collection shell 40 is symmetrically provided with fixed blocks 80, and there are two fixed blocks 80. The inner bottom wall of the oil-water collection box 20 is provided with a screw rod 81 and a guide rod 82, and the screw rod 81 is threadedly connected to one of the fixed blocks 80, and the guide rod 82 is slidingly connected to the other fixed block 80 to ensure the stability of the oil collection component lifting and lowering and improve the accuracy of oil separation. A motor 1 is provided at the bottom of the oil-water collection box 20, and the motor 1 is transmission-connected to the screw rod 81.

[0045] When the oil collecting part needs to be raised or lowered, the motor 1 will drive the screw rod 81 to rotate, and the rotation of the screw rod 81 will drive the fixed block 80 to rise or fall, so that the entire oil collecting part is raised or lowered, and the guide rod 82 improves the stability of the oil collecting part during movement.

[0046] like Figures 1 to 2 As shown, an oil cylinder 50 is provided inside the box body 10, the oil cylinder 50 is connected to the inclined tube 48, and a one-way valve is provided at the connection position between the two. A lifting assembly 30 is provided on the outer wall of the box body 10, and the lifting assembly 30 is used to lift the trash can and dump kitchen waste.
