Description

Technical Field

[0001] The invention relates to the technical field of food processing and vegetable oil production equipment, in particular to an impurity filtering device for producing high-oleic peanut oil. Background Art

[0002] High oleic peanut oil is a high-quality vegetable oil produced from high oleic acid content flowers. It has received widespread attention and recognition for its excellent health value and good stability. As a high-quality vegetable oil, it has high requirements for the purity and quality of the product. During the production process, the peanut oil raw material may contain a variety of impurities, such as fine impurities such as protein particles or plant fibers mixed in during pressing, preliminary filtration or storage; if these impurities are not effectively removed, they may cause turbidity, precipitation and even odor in the finished oil, which directly affects the quality, taste and market competitiveness of high oleic peanut oil. Therefore, an efficient impurity filtration device is needed to remove these unwanted substances.

[0003] However, in the existing impurity treatment process, peanut oil filtration equipment mostly adopts a single-layer filter plate structure, which can effectively intercept larger particle impurities, but has limited effect on removing fine suspended impurities, colloids, etc. These tiny impurities are easy to remain in the finished oil, causing oil turbidity or precipitation, especially during storage, the oxidation of impurities may accelerate the deterioration of oil.

[0004] In addition, the impurities intercepted during the filtration process carry a certain amount of grease, which is difficult to separate from the impurities by simple gravity. As a result, the grease is directly treated as waste, resulting in serious waste of grease. This not only reduces the oil yield, but also increases the cost of raw materials and production. For high-oleic peanut oil, a high-value-added product, this waste directly affects the economic benefits of the enterprise. Summary of the invention

[0010] Preferably, the first gear is meshed with the second gear, the first squeezing roller is in contact with the second squeezing roller, and the first squeezing roller and the second squeezing roller are arranged on the top of the inclined plate.

[0011] Preferably, the contact surfaces of the filter plate, the inclined plate and the guide plate are provided with a fluorocarbon coating.

[0012] Preferably, the vibration component includes a load-bearing rod, a transmission disk is arranged on the top of the load-bearing rod, an elliptical disk is rotatably connected to one side of the top of the transmission disk, a first sieve plate is arranged on one side of the elliptical disk, a second sieve plate is installed at the bottom of the first sieve plate, a plurality of adjustment rods are installed on both sides of the first sieve plate and the second sieve plate, and a plurality of dispersion columns are arranged on the top of the first sieve plate.

[0013] Preferably, the load-bearing rod is rotatably connected to the top of the second oil tank, the outer wall of the load-bearing rod is fixedly connected to a second pulley, and the outer walls of the second pulley and the first pulley are sleeved with a belt.

[0014] Preferably, the adjustment rod is slidably connected to the inner wall of the motion groove, and an oil groove is provided on the top of the second oil tank, and the oil groove is perpendicular to the first sieve plate and the second sieve plate.

[0015] Preferably, one end of the processing box is fixedly connected with a discharge plate for receiving impurities discharged by the vibrating component, and one end of the processing box is provided with an oil outlet pipe, which is communicated with the inner wall of the second oil tank and is used to discharge the filtered high oleic peanut oil.

[0016] Working principle: When high oleic peanut oil needs to be filtered for tiny impurities after processing, first connect the oil inlet pipe to the production line oil pipe through the flange, so that the peanut oil is guided through the guide plate and enters the first oil tank after being filtered by the filter plate. As the filtration volume increases, the tiny impurities carried in the peanut oil are gradually intercepted by the filter plate and deposited on the top. When the oil level in the first oil tank rises, the float begins to rise under the action of buoyancy, and through the pulling of the cable, the lever principle is used to drive the vertical rod and telescopic rod to move, so that one side of the filter plate is tilted, so that the impurities on the top are discharged synchronously, and the oil level of the first oil tank is lowered at the same time.

[0017] In this process, the cable is tightened as the multiple floats gradually rise, and the tension gradually exceeds the rebound stress of the oil inlet, thereby pushing the piston up. When the piston slides to the top of the inner wall of the valve body, the peanut oil in the first oil tank can flow into the connecting pipe through the oil inlets set on both sides of the valve body, and is further transported to the second oil tank, and finally discharged through the oil outlet pipe connected to the second oil tank.

[0018] On the other hand, the impurities on the top of the filter plate slide into the inner wall of the guide block, are caught by the inclined plate, and slide to the joint position of the second squeeze roller and the first squeeze roller along the special coating on the surface of the inclined plate. The start motor drives the second gear to rotate, and through the meshing transmission with the first gear, the second squeeze roller and the first squeeze roller rotate in opposite directions. The impurities are squeezed and extracted through the gap between the two rollers, and the squeezed peanut oil is guided to the first sieve plate and the second sieve plate for filtration, and then enters the second oil tank again.

[0019] At the same time, the impurities entering the top of the first screen plate are driven to rotate on the top of the second oil tank through the power transmission between the first pulley and the second pulley connected to the outer wall of the rotating rod. The eccentric connection between the transmission plate and the elliptical plate realizes the limited reciprocating vibration of the first screen plate and the second screen plate in multiple motion grooves. The impurities move toward the discharge plate under the action of the slope design of the screen plate, and are dispersed by the reciprocating dispersing column to further discharge the residual peanut oil. Finally, the impurities are completely separated and the entire processing process is completed.

[0020] The present invention provides an impurity filtering device for producing high oleic peanut oil. It has the following beneficial effects: 1. The present invention adopts a design of linkage between a float and a control component to realize automatic control of functions such as filter plate tilting and oil inlet opening and closing. The float drives the cable through liquid level changes to complete the filter plate tilting and automatic impurity discharge. At the same time, the control component controls the oil flow path through the action of the piston and the spring. The entire system does not require additional power, realizing full automatic operation of the equipment, which not only improves operating efficiency but also reduces operating costs.

[0021] 2. The present invention is provided with multiple layers of sieve plates and dispersing columns, which realize the graded filtration of impurities and the secondary dispersion treatment of fine impurities. The first sieve plate is used to separate larger impurities, the second sieve plate performs fine treatment on small particle impurities, and the dispersing column disperses the residual impurities during the vibration process, thereby maximizing the purity and quality of the peanut oil.

[0022] 3. The present invention effectively realizes the recovery of impurities and residual oil in peanut oil by arranging fluorocarbon coating on the surface of filter plate, inclined plate and sieve plate, and utilizing the cooperation of vibration component and extrusion roller. The fluorocarbon coating cooperates with extrusion and vibration structure to further recover the residual oil in the impurities, which significantly improves the utilization rate of peanut oil. Compared with the traditional single filtering device, it greatly reduces the waste of oil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an impurity filtering device for producing high oleic peanut oil, comprising a processing box 1, an oil inlet pipe 2 is installed on the top of the processing box 1, a guide plate 4 is fixedly connected to the top of the inner wall of the processing box 1, a first oil tank 14 is fixedly connected to one side of the middle of the inner wall of the processing box 1, a guide block 13 is fixedly connected to one side of the middle of the inner wall of the processing box 1, a first rotating shaft 5 is fixedly connected to the middle of the inner wall of the processing box 1, a filter plate 6 is rotatably connected to the top of the first rotating shaft 5, and a second rotating shaft 7 is fixedly connected to one side of the bottom of the filter plate 6. A third rotating shaft 10 is fixedly connected to one side of the inner wall of the first oil tank 14, and a plurality of vertical poles 11 are rotatably connected to the top of the third rotating shaft 10. A float 9 is fixedly connected to one end of the vertical pole 11, and a telescopic rod 12 is fixedly connected to the other end. One side of the telescopic rod 12 is rotatably connected to the outer wall of the second rotating shaft 7, and a synchronization rod 16 is fixedly connected to the bottom of the vertical pole 11. A control component is provided on the inner wall of the first oil tank 14, and the control component is connected to the synchronization rod 16 through a cable 17. A filter clamping component is provided on the inner wall of the processing box 1.

[0027] One end of the processing box 1 is fixedly connected with a discharge plate 8 for receiving impurities discharged by the vibrating component. One end of the processing box 1 is provided with an oil outlet pipe 3, which is communicated with the inner wall of the second oil tank 25 for discharging the filtered high oleic peanut oil.

[0028] Specifically, the core component of the device is a processing box 1, on the top of which is installed an oil inlet pipe 2 through a flange connection, which is connected to the oil pipeline in the production line and is used to introduce untreated peanut oil into the device. The peanut oil entering the processing box 1 first passes through a guide plate 4 fixed on the top of the inner wall, and the guide plate 4 evenly distributes the peanut oil to the filter plate 6 to ensure the flow uniformity and pressure distribution balance of the oil during the filtration process, thereby improving the filtration efficiency.

[0029] The filter plate 6 is fixed in the processing box 1 through the first rotating shaft 5 and the second rotating shaft 7. The top of the filter plate 6 is connected to the first rotating shaft 5 to realize rotation, and the bottom side is supported by the second rotating shaft 7. The filter plate 6 is used to intercept impurities in the peanut oil. When the oil passes through the filter plate 6, tiny impurities will be intercepted and deposited on the surface of the filter plate 6, and the filtered oil flows into the first oil tank 14. As the filtering process proceeds, impurities gradually accumulate on the top of the filter plate 6. In order to avoid blockage caused by impurity accumulation, the present invention adopts a dynamic adjustment structure to achieve the inclination of the filter plate 6 through the buoyancy of the float 9 and export the impurities.

[0030] A third rotating shaft 10 is fixedly connected to one side of the inner wall of the first oil tank 14, and the top of the third rotating shaft 10 is rotatably connected to multiple vertical poles 11. One end of each vertical pole 11 is fixedly connected to a floating ball 9, and the other end is connected to the second rotating shaft 7 through a telescopic rod 12. As the oil level in the first oil tank 14 rises, the floating ball 9 gradually floats up under the action of buoyancy, driving the vertical pole 11 to rotate, and pulling one side of the filter plate 6 to tilt downward through the telescopic rod 12, so that impurities automatically slide off. This design not only effectively prevents the accumulation of impurities on the filter plate 6, but also reduces the frequency of manual cleaning and improves the automation level of the equipment.

[0031] The telescopic rod 12 in the present application is an elastic telescopic rod with a spring inside which is maintained at a certain length by default. When tension or pressure acts on the telescopic rod 12, the internal spring will be compressed or stretched, thereby realizing the telescopic action. The inner wall of the float 9 is nitrogen with an air pressure of 101.3 kPa.

[0032] In order to ensure that the impurities can be discharged smoothly, the guide block 13 is fixedly connected to one side of the middle part of the inner wall of the treatment box 1. The structure of the guide block 13 is designed to receive the impurities sliding down from the top of the filter plate 6 and guide them to the discharge plate 8 located at one end of the treatment box 1. The discharge plate 8 is designed at a reasonable angle so that the impurities can be discharged smoothly from the treatment box 1, which is convenient for subsequent centralized collection and treatment.

[0033] In terms of oil treatment, the peanut oil filtered in the first oil tank 14 flows into the second oil tank 25 through the control component and is finally discharged from the oil outlet pipe 3. The oil outlet pipe is connected to the inner wall of the second oil tank 25 to ensure that the oil can be smoothly discharged to the subsequent processing flow. The control component realizes dynamic management of the oil by accurately adjusting the flow and flow rate of the oil, further improving the operating efficiency of the equipment.

[0034] Through the synergistic effect of the float 9, filter plate 6 and synchronization rod 16, not only the automatic tilting of the filter plate 6 and the efficient discharge of impurities are achieved, but also the uniform distribution of oil is ensured by the guide plate 4, thereby improving the filtration efficiency. The design of the discharge plate 8 combined with the guide block 13 makes the impurity handling process smoother, while reducing the frequency of manual intervention and maintenance. Through the graded treatment of the first oil tank 14 and the second oil tank 25, the purity and quality of the peanut oil are ensured to meet the actual needs of the production of high oleic peanut oil.

[0035] Please refer to the attached Figure 3 The control component includes a valve body 15, and multiple valve bodies 15 are fixedly connected to the inner wall of the first oil tank 14. The outer wall of the valve body 15 is provided with multiple oil inlets 18. The bottom of the cable 17 is fixedly connected to a pull rod 20, the bottom of the pull rod 20 is fixedly connected to a piston 21, and a spring 19 is provided on the top of the piston 21. The bottom of the valve body 15 is fixedly connected to a connecting pipe 24, and the connecting pipe 24 is communicated with the inner wall of the valve body 15.

[0036] The piston 21 slides on the inner wall of the valve body 15 , and the spring 19 is arranged on the inner wall of the valve body 15 , so as to push the piston 21 to close the oil inlet 18 through the stress of the spring 19 when the pull rod 20 is not pulled.

[0037] Specifically, the control component is designed to achieve flow control of the oil in the first oil tank 14. The float 9, the cable 17, and the piston 21 and the spring 19 inside the valve body 15 work together to complete the opening and closing adjustment of the oil inlet 18, thereby achieving accurate delivery of the oil. The control component includes a plurality of valve bodies 15, which are evenly and fixedly connected to the inner wall of the first oil tank 14, and are used to manage the path of the oil flowing from the first oil tank 14 to the second oil tank 25. The outer wall of the valve body 15 is provided with a plurality of oil inlets 18, and the oil inlets 18 are used for the oil to flow from the first oil tank 14 into the cavity of the valve body 15. A connecting pipe 24 is fixedly connected to the bottom of the valve body 15, and the connecting pipe 24 is communicated with the inner cavity of the valve body 15, and is used to deliver the oil entering the valve body 15 to the second oil tank 25. The piston 21 is slidably connected inside the valve body 15. The sliding track of the piston 21 in the valve body 15 is adjusted by the tie rod 20. The bottom end of the tie rod 20 is fixedly connected to the piston 21, and the top end is linked to the float 9 through the cable 17. When the oil level in the first oil tank 14 rises, the float 9 gradually floats up under the action of buoyancy. The floating of the float 9 drives the cable 17 to tighten, and then pulls the tie rod 20 upward, so that the piston 21 slides upward along the inner wall of the valve body 15, opening the oil inlet 18. Under the action of gravity and buoyancy, the oil flows into the valve body 15 through the oil inlet 18, and is further transported to the second oil tank 25 through the connecting pipe 24, completing the flow transmission of the oil.

[0038] In order to ensure the safety and stability of oil delivery, the present invention designs a spring 19 as a reset device, which is installed in the top area inside the valve body 15 and contacts the piston 21. When the oil level drops or the float 9 falls back, the cable 17 loses its tension, and the spring 19 pushes the piston 21 to slide downward under the action of its own elastic force, thereby closing the oil inlet 18, effectively preventing the oil from flowing back or foreign impurities from entering the first oil tank 14. This design allows the opening and closing action of the oil inlet 18 to be automatically adjusted as the oil level changes, without the need for an additional power source, and has high automation and reliability.

[0039] The sliding part of the piston 21 is tightly matched with the inner wall of the valve body 15, and its sealing performance is ensured by high-precision processing to prevent oil leakage or gas from entering the system. At the same time, the design of the connecting pipe 24 ensures that the oil can quickly flow to the second oil tank 25 when the oil inlet 18 is opened, avoiding blockage or unstable flow rate during oil transmission.

[0040] Please refer to the attached Figure 4 -Attached Figure 6The filter clamping assembly includes a vertical plate 22, and multiple vertical plates 22 are fixedly connected to the inner wall of the processing box 1. Multiple movement grooves 23 are opened on the adjacent side of the two vertical plates 22, which are used to control the movement stroke of the vibration component on one side of the filter clamping assembly. A protective plate 27 is installed on the inner wall of the vertical plate 22, and a second oil tank 25 is installed at the bottom of the vertical plate 22. A motor 28 is fixedly connected to the top of the second oil tank 25, and a second gear 31 is fixedly connected to the output end of the motor 28. A second squeezing roller 33 is fixedly connected to the top of the second gear 31. A rotating rod 29 is rotatably connected to the top of the second oil tank 25, and a first gear 30 is fixedly connected to the outer wall of the rotating rod 29. The top of the rotating rod 29 is fixedly connected to the first squeezing roller 32, and the rotating rod 29 is rotatably connected to the bottom of the protective plate 27.

[0041] The first gear 30 is meshed with the second gear 31 , and the first squeezing roller 32 is in contact with the second squeezing roller 33 . The first squeezing roller 32 and the second squeezing roller 33 are arranged on the top of the inclined plate 26 .

[0042] Specifically, the filter clamp assembly is used to further process the impurities separated during the peanut oil filtration process. Its design can not only effectively squeeze the impurities to recover the residual oil, but also smoothly discharge the impurities from the device through vibration and transmission mechanisms. The structure of the filter clamp assembly includes components such as a vertical plate 22, a moving groove 23, a protective plate 27, a second oil tank 25, a motor 28, a gear transmission mechanism and a squeezing roller, which cooperate with each other to achieve the functions of squeezing, filtering and discharging impurities.

[0043] The core support structure of the filter clamp assembly is a plurality of vertical plates 22, which are fixedly mounted on the inner wall of the treatment box 1 to provide stable support for the vibration components and the extrusion mechanism. A plurality of movement grooves 23 are arranged on the inner side of two adjacent vertical plates 22, which are used to limit the range of motion of the vibration components and ensure that the vibration and extrusion of the filter clamp assembly during operation are precisely controllable. In order to enhance the overall durability of the device, a protective plate 27 is installed on the inner wall of the vertical plate 22, which can not only reduce the wear generated during the vibration process, but also provide additional protection for the internal components during high-speed operation.

[0044] A second oil tank 25 is installed at the bottom of the filter assembly. The second oil tank 25 is used to receive the oil recovered after extrusion and filtration, and transport it to the subsequent processing unit through the oil outlet pipe 3. A motor 28 is fixedly connected to the top of the second oil tank 25. The motor 28 provides power support for the extrusion mechanism, and its output end is connected to the second gear 31 through an axis. A second extrusion roller 33 is fixedly connected to the top of the second gear 31, which is driven by gear transmission to extrude impurities during operation. At the same time, the top of the second oil tank 25 is also rotatably connected to a rotating rod 29, the outer wall of the rotating rod 29 is fixedly connected to the first gear 30, and the top is fixedly connected to the first extrusion roller 32. The first gear 30 and the second gear 31 are transmission-connected through precise meshing to ensure that the first extrusion roller 32 and the second extrusion roller 33 rotate in opposite directions during operation.

[0045] The design of the squeezing roller plays an important role in the impurity treatment process. The first squeezing roller 32 and the second squeezing roller 33 are fitted together and arranged on the top of the inclined plate 26. The inclined plate 26 is used to guide the impurities sliding off the filter plate 6 into the squeezing mechanism. In the working state, the impurities slide into the gap between the two squeezing rollers along the inclined plate 26. Under the action of the squeezing rollers rotating in opposite directions, the impurities are fully squeezed, thereby separating the residual grease. The squeezed oil is guided to the second oil tank 25 through the inclined plate 26 to achieve secondary recovery of the oil, while the impurities continue to be guided to the subsequent discharge channel.

[0046] In order to ensure the stability and efficiency of the squeezing roller operation, the rotating rod 29 is rotatably connected to the bottom of the protective plate 27. This design not only improves the durability of the squeezing mechanism, but also enables the entire filter assembly to maintain high stability during high-speed operation. Through the precise meshing design of the gear transmission mechanism, the first gear 30 and the second gear 31 achieve efficient power transmission, ensuring that the squeezing rollers rotate synchronously and without slipping. The fitting design of the first squeezing roller 32 and the second squeezing roller 33 further enhances the squeezing effect, so that the impurities are almost completely de-oiled after squeezing.

[0047] Through the above structure, the filter assembly achieves efficient treatment of impurities. Its design can not only maximize the recovery of residual oil and improve the overall utilization rate of peanut oil, but also ensure the stability and durability of the device through the coordinated design of the moving groove 23 and the protective plate 27, thereby reducing the risk of failure and maintenance requirements during equipment operation.

[0048] Please refer to the attached Figure 1 The contact surfaces of the filter plate 6, the inclined plate 26 and the guide plate 4 are provided with a fluorocarbon coating.

[0049] Specifically, the fluorocarbon coating is a material with ultra-low surface energy, excellent oleophobicity, anti-adhesion and corrosion resistance, and plays a key role in the filtration and impurity separation process of the device.

[0050] The filter plate 6 is the core component of the peanut oil filtration device. The role of the fluorocarbon coating on its surface is mainly reflected in the following aspects: First, the low surface energy of the fluorocarbon coating makes it have extremely low adhesion to grease and impurities, which can effectively prevent impurities from accumulating on the surface of the filter plate 6 and avoid the decrease in filtration efficiency due to clogging by impurities. Secondly, the surface of the coating is very smooth, which can significantly reduce the friction resistance of peanut oil when it flows through the filter plate 6, improve the fluidity of the oil, and thus improve the overall filtration efficiency. In addition, the fluorocarbon coating has good wear resistance, which can maintain the surface integrity of the filter plate 6 during long-term operation and extend the service life of the equipment.

[0051] The main function of the inclined plate 26 is to guide the impurities to slide to the extrusion assembly. The fluorocarbon coating on its surface can further optimize the separation effect of impurities. When the impurities slide from the filter plate 6 to the inclined plate 26, the oleophobicity and anti-adhesion properties of the fluorocarbon coating allow the impurities to slide quickly without being retained or accumulated due to adhesion, ensuring that the impurities can smoothly enter the first extrusion roller 32 and the second extrusion roller 33 for secondary processing. At the same time, the smooth surface of the inclined plate 26 prevents impurities from wearing or corroding the plate surface, allowing the inclined plate 26 to maintain stable performance in a high-frequency use environment.

[0052] The function of the guide plate 4 is to guide the peanut oil to be evenly distributed when entering the filter plate 6. The fluorocarbon coating on its contact surface reduces the adhesion of oil, allowing the oil to flow smoothly to the filter plate 6, effectively avoiding the uneven distribution problem caused by the oil adhering to the surface of the guide plate 4. At the same time, the corrosion resistance of the coating ensures that the guide plate 4 will not be damaged when it is in contact with peanut oil and its impurities for a long time, thereby ensuring the continuous effectiveness of the guiding function.

[0053] In addition, the chemical inertness of the fluorocarbon coating enables it to withstand the high temperature, high humidity and complex chemical environment in the peanut oil production process, and will not fall off or degrade due to temperature changes or long-term use. This feature ensures the long-term reliability and stability of the device.

[0054] Please refer to the attached Figure 7 -Attached Figure 8 The vibration component includes a load-bearing rod 36, a transmission disk 37 is arranged on the top of the load-bearing rod 36, an elliptical disk 38 is rotatably connected to the top side of the transmission disk 37, a first sieve plate 39 is arranged on one side of the elliptical disk 38, a second sieve plate 40 is installed at the bottom of the first sieve plate 39, a plurality of adjustment rods 42 are installed on both sides of the first sieve plate 39 and the second sieve plate 40, and a plurality of breaking columns 41 are arranged on the top of the first sieve plate 39.

[0055] The load-bearing rod 36 is rotatably connected to the top of the second oil tank 25 , and the outer wall of the load-bearing rod 36 is fixedly connected to the second pulley 35 , and the outer wall of the second pulley 35 and the first pulley 34 are sleeved with a belt.

[0056] The adjusting rod 42 is slidably connected to the inner wall of the moving groove 23 . An oil groove is provided on the top of the second oil tank 25 . The oil groove is perpendicular to the first sieve plate 39 and the second sieve plate 40 .

[0057] Specifically, the core support structure of the vibration component is a load-bearing rod 36, the top of which is rotatably connected to the top of the second oil tank 25 through a bearing, and is used to provide rotation and support functions for the vibration system. The outer wall of the load-bearing rod 36 is fixedly connected to a second pulley 35, which is connected to the first pulley 34 through a belt to achieve a transmission connection. During operation, external power drives the second pulley 35 to rotate through the first pulley 34, thereby driving the load-bearing rod 36 to rotate on the top of the second oil tank 25, providing power support for the entire vibration system.

[0058] A transmission disc 37 is fixedly installed on the top of the load-bearing rod 36. The transmission disc 37 is used to convert the rotational motion into the vibration motion. An elliptical disc 38 is rotatably connected to one side of the top. The asymmetric design of the elliptical disc 38 is the key to realizing the vibration function. The elliptical eccentric axis drives the vibration system to produce periodic vibration, so that the screen plate can achieve reciprocating vibration in the motion groove 23. The motion groove 23 is opened on the inner wall of the vertical plate 22 to limit the vibration range of the screen plate, ensure that the vibration action is carried out within the designed stroke range, and avoid the screen plate from being offset or damaged.

[0059] The first sieve plate 39 is arranged on one side of the elliptical disk 38, and is slidably connected to the motion groove 23 through an adjustment rod 42, so as to achieve precise matching with the vertical plate 22. A second sieve plate 40 is installed at the bottom of the first sieve plate 39. The design of the two-layer sieve plate can grade and screen impurities. The first sieve plate 39 is mainly used to separate larger impurities, and the second sieve plate 40 is used to process finer impurity particles, thereby ensuring the comprehensiveness and accuracy of impurity processing. Multiple adjustment rods 42 are installed on both sides of the sieve plate. The sliding design of the adjustment rods 42 allows the sieve plate to adapt to the needs of different vibration amplitudes, and can adjust the vibration stroke and inclination angle of the sieve plate according to the characteristics of specific impurities, thereby improving the adaptability and flexibility of the device.

[0060] In order to further improve the impurity dispersion effect, a plurality of dispersing columns 41 are installed on the top of the first sieve plate 39. The dispersing columns 41 disperse the impurities on the sieve plate by the impact generated during the vibration process, thereby causing the grease remaining in the impurities to be fully released and flow through the sieve plate into the oil tank at the bottom of the second oil tank 25. The oil tank is vertically arranged below the first sieve plate 39 and the second sieve plate 40, and is used to receive the separated grease and transport it to the downstream processing equipment through the oil outlet pipe 3, while the separated impurities slide along the surface of the sieve plate and are finally discharged to the outside of the device.

[0061] The vibration component of the present invention realizes efficient vibration function through the linkage of the load-bearing rod 36, the transmission plate 37 and the elliptical plate 38. The multi-layer design of the sieve plate and the adjustable structure of the adjustment rod 42 ensure the efficient separation of impurities of different sizes. In addition, the coordinated design of the scattering column 41 and the oil tank further improves the efficiency of residual oil recovery during the impurity separation process.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
