Description

Technical Field

[0001] This application relates to the technical field of kitchen waste treatment, and particularly to a kitchen waste oil-water separation device. Background Art

[0002] Currently, with the acceleration of the urbanization process, the treatment of kitchen waste has become an important environmental issue. Kitchen waste contains a large amount of oil and water. If these components are not effectively separated, it will not only increase the difficulty of waste treatment but also cause environmental pollution. Therefore, it is of great practical significance to develop efficient and environmentally friendly kitchen waste oil-water separation technologies. In related technologies, the treatment methods for kitchen waste mainly include physical methods, chemical methods, biological methods, and other means. Among them, physical methods mainly include unit operations such as solid-liquid separation and oil-water separation. Specifically, solid-liquid separation usually adopts methods such as pressure filtration or centrifugation to separate solid substances and liquids in kitchen waste; oil-water separation mostly uses the gravity sedimentation method, relying on the density difference between oil and water to separate oil and water under the action of gravity.

[0003] Regarding the above related technologies: Using the gravity sedimentation method to separate oil and water requires a long time to achieve a good separation effect. Therefore, there is a problem of low separation efficiency. Summary of the Invention

[0004] In order to improve the separation efficiency, this application provides a kitchen waste oil-water separation device.

[0005] The kitchen waste oil-water separation device provided by this application adopts the following technical solutions: A kitchen waste oil-water separation device includes: Collection mechanisms, with at least two provided. Each collection mechanism is provided with a filtration component, and the filtration component is used to separate oil and water; Moving mechanisms, respectively connected to multiple collection mechanisms. The moving mechanisms are used to drive the collection mechanisms to move so that one of the multiple collection mechanisms can collect oil and water; Cooling mechanisms, connected to the collection mechanisms. The cooling mechanisms are used to reduce the temperature inside the collection mechanisms.

[0006] By adopting the above technical solution, when oil-water separation is required, the moving mechanism can drive the collecting mechanism to move to a designated position, so as to convey the oil and water to be separated into the collecting mechanism. And after the collecting mechanism has collected a sufficient amount of oil and water, the moving mechanism drives the collecting mechanism to move and moves a new collecting mechanism to the designated position, so as to continuously receive oil and water. At this time, the collecting mechanism that has collected a sufficient amount of oil and water is in a static state, and the cooling mechanism reduces the temperature inside the collecting mechanism, so that the viscosity of the oil increases and the oil droplets are more likely to coagulate, thus facilitating the better separation of oil and water by the filtering component, and further contributing to improving the oil-water separation efficiency and separation effect.

[0007] Optionally, the collecting mechanism includes a separation tank and a collecting box. The separation tank is respectively connected to the moving mechanism and the cooling mechanism. A sewage discharge component is communicated with the separation tank. The filtering component is arranged in the separation tank and close to the sewage discharge component. The collecting box is detachably connected in the separation tank and close to the filtering component. The collecting box is used for collecting oil. The sewage discharge component is used for discharging the sewage in the separation tank.

[0008] By adopting the above technical solution, the moving mechanism can adjust the position of the separation tank, and the cooling mechanism can reduce the temperature inside the separation tank, thus facilitating the improvement of the oil-water separation efficiency. And the filtering component is arranged in the separation tank close to the sewage discharge component, so that when discharging the sewage through the sewage discharge component, the filtering component can filter oil and water to prevent the oil from being discharged from the sewage discharge component along with the sewage, and can collect the oil in the collecting box. At the same time, the collecting box is detachably connected to the separation tank, which is convenient for regular cleaning and replacement. This not only improves the collection efficiency of the oil, but also reduces the oil content that may be entrained during the sewage discharge process, thereby enhancing the overall oil-water separation effect and reducing environmental pollution.

[0009] Optionally, the filtering component includes a flexible filtering membrane. The flexible filtering membrane is arranged in the separation tank. The flexible filtering membrane is located on the side of the collecting box close to the sewage discharge component. The flexible filtering membrane is used for filtering oil and water.

[0010] By adopting the above technical solution, the flexible filtering membrane is arranged in the separation tank and on the side of the collecting box close to the sewage discharge component, which can effectively intercept the oil in the oil-water mixture and prevent the oil from being discharged together with the sewage. At the same time, the flexible filtering membrane has good adaptability and filtering performance, and can efficiently separate oil and water, thus improving the oil-water separation efficiency.

[0011] Optionally, the filter assembly includes a rotating drive member, a unwinding roller and a winding roller, the unwinding roller and the winding roller are symmetrically arranged on the separation box, the flexible filter membrane is wound around the unwinding roller, one end of the flexible filter membrane passes through the separation box and is connected to the winding roller, the rotating drive member is arranged on the separation box and connected to the winding roller, and the rotating drive member is used to drive the winding roller to rotate.

[0012] By adopting the above technical solution, the flexible filter membrane can be moved from the unwinding roller to the winding roller driven by the rotating drive member, thereby realizing continuous replacement of the new filter surface. This not only avoids the problem of flexible filter membrane clogging due to long-term use, but also ensures efficient oil-water separation performance. At the same time, the dynamic renewal process of the flexible filter membrane can effectively reduce the retention time of the oil-water mixture on the filter surface, further improving the oil-water separation efficiency and grease recovery rate. In addition, this design simplifies maintenance operations and extends the overall service life of the equipment.

[0013] Optionally, a limiting block is provided on the inner wall of the separation box, a limiting groove is provided on the limiting block along the height direction of the separation box, and the flexible filter membrane is slidably inserted in the limiting groove and fits against the inner wall of the limiting groove.

[0014] By adopting the above technical solution, the flexible filter membrane is slidably inserted into the limit groove in the separation box and fits with the inner wall of the limit groove, which can ensure that the flexible filter membrane remains stable during movement and avoid poor oil-water separation effect due to position offset. At the same time, this design can also make it more convenient to replace or clean the flexible filter membrane, improving the maintainability and ease of operation of the equipment. In addition, the design of the limit block and the limit groove can also effectively prevent the deformation and damage of the flexible filter membrane during operation, extend the service life of the flexible filter membrane, and further improve the reliability and efficiency of the overall equipment.

[0015] Optionally, the winding roller is located below the unwinding roller, and a guide block is provided on the collecting box, and the guide block is in contact with the side of the flexible filter membrane facing away from the sewage discharge assembly. When the flexible filter membrane moves, the guide block can guide the oil adhered to the flexible filter membrane into the collecting box.

[0016] By adopting the above technical solution, the guide block on the collection box is tightly fitted with the side of the flexible filter membrane away from the sewage discharge component. When the flexible filter membrane moves, the guide block can effectively scrape off the oil adhering to the surface of the flexible filter membrane and guide it into the collection box. This design not only improves the collection efficiency of the oil, but also reduces the possibility of oil remaining on the flexible filter membrane, thereby ensuring the cleanliness and grease recovery rate in the subsequent processing process.

[0017] Optionally, a sealing gasket is provided between the flexible filter membrane and the separation box.

[0018] By adopting the above technical solution, a sealing gasket is arranged between the flexible filter membrane and the separation box, which can effectively prevent the oil-water mixture from leaking from the gap between the flexible filter membrane and the separation box, thereby ensuring the high efficiency and stability of the oil-water separation process. The arrangement of the sealing gasket can also extend the service life of the flexible filter membrane, reduce the maintenance frequency, and thus improve the reliability and economy of the entire equipment.

[0019] Optionally, the cooling mechanism includes a cooling plate, a cooling pipe is embedded in the cooling plate, the cooling plate is in contact with an outer wall of the separation box, and the cooling pipe is used to transport a refrigerant.

[0020] By adopting the above technical solution, the cooling pipe embedded in the cooling plate can effectively reduce the temperature of the cooling plate, so that the cooling plate can quickly take away the heat inside the separation box, thereby reducing the temperature inside the separation box and improving the oil-water separation efficiency. At the same time, the cooling plate fits the inner wall of the separation box, which makes the cold transfer more uniform and efficient on the one hand, and reduces the possibility of the cooling plate interfering with the movement of the separation box on the other hand, thereby effectively improving the stability of the equipment operation.

[0021] Optionally, the sewage discharge assembly includes a sewage discharge pipe and a sewage discharge valve arranged on the sewage discharge pipe, the sewage discharge pipe is arranged on the separation box, and the sewage discharge pipe is located on a side of the filter assembly away from the collection box.

[0022] By adopting the above technical solution, the sewage pipe and the sewage valve cooperate with each other to ensure that the sewage in the separation box can be discharged smoothly and avoid mixing with the oil in the collection box, thereby improving the efficiency and purity of oil-water separation. At the same time, the setting of the sewage valve makes the operation more convenient, and the sewage discharge can be controlled at any time according to needs, further optimizing the operation effect of the entire system.

[0023] Optionally, it includes a frame and a crushing mechanism and a solid-liquid separation mechanism which are sequentially arranged on the frame, the collecting mechanism, the moving mechanism and the cooling mechanism are respectively arranged on the frame, the solid-liquid separation mechanism is located above the collecting mechanism, and the crushing mechanism is located above the solid-liquid separation mechanism and is connected to the solid-liquid separation mechanism.

[0024] By adopting the above technical solution, firstly, the crushing mechanism can break large particulate matter in kitchen waste into small particles, making the subsequent solid-liquid separation more thorough. Secondly, the solid-liquid separation mechanism is arranged below the crushing mechanism and can directly receive the materials after crushing treatment and further separate them into solid and oil-water components. This not only improves the efficiency of the overall system but also ensures that the mixture entering the collection mechanism is mainly the initially separated mixture, reducing the workload of the collection mechanism. Moreover, due to the presence of the cooling mechanism, oil-water separation can be carried out at a lower temperature, avoiding the deterioration or volatilization loss of grease caused by high temperature. In summary, this technical solution significantly improves the effect of kitchen waste oil-water separation, increases the grease recovery rate, and also reduces energy consumption and maintenance costs.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the mutual cooperation of the collection mechanism, the filtration component, the moving mechanism and the cooling mechanism, the efficiency and effect of oil-water separation are effectively improved; 2. Through the mutual cooperation of the flexible filtration membrane, the rotation driving member, the unwinding roller and the winding roller, the flexible filtration membrane can move from the unwinding roller to the winding roller driven by the rotation driving member, so as to realize continuous replacement of a new filtration surface, thereby effectively avoiding the problem of blockage of the flexible filtration membrane caused by long-term use, simplifying the maintenance operation to a certain extent, and prolonging the overall service life of the equipment; 3. The setting of the guiding block enables the guiding block to effectively scrape off the oil adhered to the surface of the flexible filtration membrane and guide it to the collection box when the flexible filtration membrane moves, thereby effectively improving the collection efficiency of the oil and reducing the possibility of oil remaining on the flexible filtration membrane.

[0033] An embodiment of this application discloses a kitchen waste oil-water separation device.

[0035] Referring to Figure 1 and Figure 2 , the kitchen waste oil-water separation device includes a collection mechanism 1, a moving mechanism 2, a cooling mechanism 3, a frame 4, a crushing mechanism 5 and a solid-liquid separation mechanism 6. Among them, the collection mechanism 1, the moving mechanism 2 and the cooling mechanism 3 are respectively arranged on the frame 4, and the moving mechanism 2 and the cooling mechanism 3 are respectively connected to the collection mechanism 1. The solid-liquid separation mechanism 6 is located above the collection mechanism 1, and the crushing mechanism 5 is located above the solid-liquid separation mechanism 6 and is communicated with the solid-liquid separation mechanism 6, so as to facilitate the use of the crushing mechanism 5 to crush large-particle substances in the kitchen waste into small particles, and then use the solid-liquid separation mechanism 6 to separate the oil and water in the material after crushing treatment, so that the oil and water enter the collection mechanism 1, and thus realize oil-water separation.

[0036] In this embodiment, the crushing mechanism 5 can adopt a blade design, and the blades are made of high-speed steel, which are sharp and wear-resistant. A hammer crusher can also be used, which is suitable for processing hard garbage. The solid-liquid separation mechanism 6 can adopt a vibration screening method to shake off the liquid through high-frequency vibration, or a pressing roller can be used to extrude the liquid through pressure.

[0037] It should be noted that the specific structures of the crushing mechanism 5 and the solid-liquid separation mechanism 6 are conventional technical means for those skilled in the art. Therefore, no further elaboration will be made in the embodiments of this application.

[0038] Referring to Figure 3 and Figure 4 , at least two collecting mechanisms 1 are provided, and multiple collecting mechanisms 1 are respectively arranged below the solid-liquid separation mechanism 6. In this embodiment, two collecting mechanisms 1 are provided, and a filtering component 11 is arranged on each collecting mechanism 1, and the filtering component 11 is used to separate oil and water.

[0039] Referring to Figure 2 and Figure 4 , the collecting mechanism 1 includes a separation box 12 and a collecting box 13. Among them, the separation box 12 is respectively connected to the moving mechanism 2 and the cooling mechanism 3, a sewage discharge component 14 is communicated with the separation box 12, and the filtering component 11 is arranged in the separation box 12 and close to the sewage discharge component 14. And the collecting box 13 is detachably connected in the separation box 12 and close to the filtering component 11, and the collecting box 13 is used to collect oil liquid, and the sewage discharge component 14 is used to discharge the sewage in the separation box 12.

[0040] In this embodiment, the separation box 12 can be made of stainless steel, which has good corrosion resistance and durability, or high-strength plastic can also be used to reduce the weight of the equipment and facilitate handling and installation. The collecting box 13 can also be selected from stainless steel or high-strength plastic to ensure that it will not deform or be damaged during long-term use.

[0041] Referring to Figure 4 , a sliding groove 121 is formed on the separation box 12, and the collecting box 13 is slidably inserted into the sliding groove 121 and passes through the sliding groove 121 and enters the separation box 12, so as to facilitate the disassembly and assembly of the collecting box 13 for convenient regular cleaning and replacement. In this embodiment, the collecting box 13 is fixed to the separation box 12 by screws, and a sealing structure (not shown in the figure) is arranged between the collecting box 13 and the separation box 12 to prevent oil and water leakage. In other embodiments, the collecting box 13 can also be connected and fixed to the separation box 12 by magnets.

[0042] Referring to Figure 4 , the sewage discharge component 14 includes a sewage discharge pipe 141 and a sewage discharge valve 142 installed on the sewage discharge pipe 141. Among them, the sewage discharge pipe 141 is communicated with the separation box 12, so as to facilitate the discharge of the sewage in the separation box 12 through the sewage discharge pipe 141. In this embodiment, the sewage discharge pipe 141 can be made of PVC material with strong corrosion resistance, or stainless steel material can also be used to extend the service life. The sewage discharge valve 142 can be a manual gate valve with simple operation, or an electromagnetic valve to achieve automatic control.

[0043] It should be noted that in the embodiments of the present application, the sewage discharge pipe 141 can be connected to the sewage treatment equipment through a hose or a telescopic pipe to facilitate the transportation of sewage into the sewage treatment equipment for treatment. As for how to specifically set up the sewage treatment equipment, for those skilled in the art, it belongs to conventional technical means. Therefore, it will not be elaborated too much in the embodiments of the present application.

[0044] Referring to Figure 4 , on the inner wall of the separation box 12, a limiting block 122 is fixedly connected. The limiting block 122 is arranged along the height direction of the separation box 12, and a limiting groove 1221 is opened along the height direction of the separation box 12 on the limiting block 122. In this embodiment, there are two limiting blocks 122, and the two limiting blocks 122 are symmetrically arranged.

[0045] Referring to Figure 2 and Figure 4 , the filtering component 11 includes a flexible filtering membrane 111, a rotation driving member 112, a unwinding roller 113, and a winding roller 114. Among them, the unwinding roller 113 and the winding roller 114 are symmetrically installed on the separation box 12, and the winding roller 114 is located below the unwinding roller 113. The flexible filtering membrane 111 is wound around the unwinding roller 113, and one end of the flexible filtering membrane 111 passes through the separation box 12 and is connected to the winding roller 114.

[0046] In another preferred embodiment, the rotation driving member 112, the unwinding roller 113, and the winding roller 114 may not be provided, and the flexible filtering membrane 111 may be directly detachably connected inside the separation box 12.

[0047] The rotation driving member 112 is installed on the separation box 12 and fixedly connected to the winding roller 114. In this embodiment, the rotation driving member 112 is a servo motor to facilitate driving the winding roller 114 to rotate, thereby realizing the automatic replacement of the flexible filtering membrane 111 and reducing manual intervention. In other embodiments, a servo motor may also be connected to the unwinding roller 113, and the unwinding roller 113 and the winding roller 114 may be rotated synchronously to reduce the tension on the flexible filtering membrane 111 and avoid damage to the flexible filtering membrane 111.

[0048] Referring to Figure 4 , the part of the flexible filtering membrane 111 located inside the separation box 12 is on the side of the collection box 13 close to the sewage discharge pipe 141, and the part of the flexible filtering membrane 111 located inside the separation box 12 is slidably inserted into the limiting groove 1221 and fits with the inner wall of the limiting groove 1221. This can ensure that the flexible filtering membrane 111 remains flat during movement, avoid wrinkles or offsets, and ensure the filtering effect.

[0049] When it is necessary to drain the sewage in the separation tank 12, the sewage discharge valve 142 is opened, and the sewage passes through the flexible filter membrane 111 and is discharged through the sewage discharge pipe 141. At this time, the flexible filter membrane 111 intercepts the oil liquid in the separation tank 12. At the same time, the oil liquid will flow towards the direction close to the flexible filter membrane 111 along with the sewage. As the sewage in the separation tank 12 decreases, a part of the oil liquid will adhere to the flexible filter membrane 111, and another part of the oil liquid will fall into the collection box 13 to achieve the collection of the oil liquid.

[0050] Referring to Figure 4 , a guiding block 131 is fixedly connected to the collection box 13, and the guiding block 131 is attached to the side of the flexible filter membrane 111 facing away from the sewage discharge pipe 141. When the flexible filter membrane 111 moves, the guiding block 131 can effectively scrape off the oil liquid adhered to the surface of the flexible filter membrane 111 and guide it into the collection box 13. This design not only improves the collection efficiency of the oil liquid but also reduces the possibility of the oil liquid remaining on the flexible filter membrane 111, thus ensuring the cleanliness and oil recovery rate in the subsequent treatment process.

[0051] In this embodiment, the surface of the guiding block 131 is smooth, reducing the frictional resistance and at the same time increasing the flow rate of the oil liquid. The guiding block 131 can be made of stainless steel material with strong corrosion resistance, or a Teflon coating can be used to reduce the adhesion of the oil liquid.

[0052] Referring to Figure 5 , a sealing gasket 123 is provided between the flexible filter membrane 111 and the separation tank 12 to play a sealing role and prevent sewage leakage. The sealing gasket 123 can be made of rubber material, which is soft and has good elasticity, or silicone material can be used, which has better heat resistance.

[0053] Referring to Figure 2 , the moving mechanism 2 includes a motor 21, a lead screw 22 and a guide rail 23. Among them, the motor 21 is installed on the frame 4, the lead screw 22 is rotatably connected to the frame 4, and one end of the lead screw 22 is fixedly connected to the output end of the motor 21. The lead screw 22 is threadedly connected to the two separation tanks 12 respectively. The guide rail 23 is installed on the frame 4 and is located beside the lead screw 22, and the two separation tanks 12 are respectively slidably connected to the guide rail 23, so as to facilitate using the motor 21 and the lead screw 22 to drive the two separation tanks 12 to move reciprocally.

[0054] Referring to Figure 2 and Figure 4, when it is necessary to separate oil and water, first start the motor 21. The motor 21 drives one of the two separation tanks 12 to move below the solid-liquid separation mechanism 6 through the lead screw 22, so as to facilitate receiving the oil and water separated by the solid-liquid separation mechanism 6. And after a sufficient amount of oil and water is collected in one separation tank 12, the motor 21 drives this separation tank 12 to move away from the solid-liquid separation mechanism 6 through the lead screw 22, and moves the other separation tank 12 below the solid-liquid separation mechanism 6 to collect oil and water, thereby realizing the switching of the two separation tanks 12. At this time, the previously collected separation tank 12 with a sufficient amount of oil and water is in a static state, which on the one hand facilitates the automatic stratification of oil and water, and on the other hand provides sufficient cooling and solidification time for the oil liquid to facilitate the separation of oil and water, and thus is conducive to improving the separation efficiency.

[0055] In other embodiments, the moving mechanism 2 may also be provided with two sets of cylinders to push the two separation tanks 12 to move reciprocally.

[0056] Refer to Figure 2 , the cooling mechanism 3 includes a cooling plate 31. The cooling plate 31 is installed on the frame 4. A cooling pipe 32 is embedded in the cooling plate 31, and the cooling pipe 32 is used to convey a refrigerant to reduce the temperature of the cooling plate 31. In this embodiment, the cooling plate 31 can be made of copper with high heat transfer efficiency, or it can also be made of aluminum with low cost. The refrigerant can be cold water, which is simple and easy to obtain, or it can be a refrigerant, which is suitable for working in a low-temperature environment.

[0057] The cooling plate 31 is attached to the outer wall of the separation tank 12, so that on the one hand, it is convenient to quickly take away the heat inside the separation tank 12 by using the cooling plate 31 to reduce the temperature inside the separation tank 12 and improve the oil-water separation efficiency; on the other hand, it reduces the possibility of the cooling plate 31 interfering with the movement of the separation tank 12, and thus effectively improves the stability of the equipment operation.

[0058] In other embodiments, the cooling mechanism 3 can also be set as a cold cabinet, and the separation tank 12 is transported into the cold cabinet for cooling to improve the cooling efficiency.

[0059] The implementation principle of a kitchen waste oil-water separation device in an embodiment of this application is as follows: When it is necessary to separate oil and water from kitchen waste, the kitchen waste is first conveyed to the crushing mechanism 5 for crushing, and the crushed waste is conveyed to the solid-liquid separation mechanism 6 for solid-liquid separation. At this time, a separation box 12 is located below the solid-liquid separation mechanism 6 to collect the separated oil and water. After a sufficient amount of oil and water is collected in the separation box 12, the motor 21 drives the separation box 12 to move away from the solid-liquid separation mechanism 6 through the lead screw 22, and moves another separation box 12 to the lower part of the solid-liquid separation mechanism 6. At this time, the separation box 12 that has previously collected a sufficient amount of oil and water is in a static state, and the internal oil and water gradually stratify. Under the action of the cooling mechanism 3, the oil gradually solidifies or becomes viscous. Then, the sewage discharge valve 142 is opened, so that the sewage in the separation box 12 is discharged through the sewage discharge pipe 141, and the solidified or viscous oil is intercepted in the separation box 12 by the flexible filter membrane 111. At this time, part of the oil enters the collection box 13, and another part of the oil adheres to the flexible filter membrane 111, thereby realizing oil-water separation.

[0060] In an embodiment of this application, by setting multiple collection mechanisms 1, more kitchen waste can be processed at the same time, improving work efficiency. The addition of the moving mechanism 2 enables each collection mechanism 1 to quickly switch when needed, avoiding downtime waiting time and increasing the continuous operation ability of the device. The design of the cooling mechanism 3 effectively reduces the temperature in the separation box 12, prevents oil-water emulsification, and improves the recovery rate of grease. The use of the flexible filter membrane 111 not only improves the filtration accuracy but also can be replaced regularly, reducing the maintenance cost. The operation of the entire device is simple and easy to maintain, suitable for various scales of urban kitchen waste treatment scenarios, and significantly improves the resource utilization rate of kitchen waste.

[0061] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
