Abstract
Description
Technical Field
[0001] This application relates to the field of waste lubricating oil treatment technology, and in particular to a multi-component separation device for waste lubricating oil with combined functions. Background Technology
[0002] Waste lubricating oil contains a large amount of recyclable base oil. After treatment and regeneration, it can be reused in the production of lubricating oil, fuel oil, and other products, effectively conserving petroleum resources. Statistics show that with proper treatment of waste lubricating oil, the base oil recovery rate can reach 60%–80%. Traditional waste lubricating oil separation methods, such as simple sedimentation and filtration, have low separation efficiency and cannot meet the needs of large-scale industrial processing. In situations requiring rapid processing of large quantities of waste lubricating oil with high purity requirements for the separated components, this type of combined-function separation device is necessary. For example, large automobile repair shops and ship repair bases generate large amounts of waste lubricating oil daily. To effectively separate the base oil, additives, and metallic impurities to ensure the base oil meets high recycling standards, this device is required. Through a combination of separation technologies, such as centrifugation, distillation, and adsorption, it can significantly improve separation efficiency while ensuring the purity of each component, enabling the separated base oil to meet the quality requirements for re-production of lubricating oil or other oil products.
[0003] Waste lubricating oil has a complex composition, containing base oil, additives, metallic impurities, oxidation products, and other components. This device combines centrifugal separation, distillation, and adsorption technologies to specifically treat components with different properties. Centrifugal separation utilizes the centrifugal force generated by high-speed rotation to quickly separate impurities such as denser metal particles; distillation technology separates base oil from other substances based on the differences in the boiling points of each component; and adsorption technology uses special adsorbent materials to remove residual organic pollutants and pigments. The synergistic operation of these multiple technologies greatly improves separation efficiency. Compared to traditional simple treatment methods, it can process large quantities of waste lubricating oil in a shorter time while ensuring separation accuracy.
[0004] In existing technologies, some multi-component waste lubricating oil separation devices with combined functions struggle to vibrate the filter plates, leading to a large accumulation of impurities. This not only reduces filtration efficiency but also increases the burden on the filter plates and related components. To maintain a certain throughput, the equipment must operate under overload for extended periods, accelerating filter plate wear and aging. This results in enlarged pores, cracks, and other damage, causing a rapid decline in filtration accuracy. Frequent filter plate replacements not only increase component procurement costs but also cause production interruptions due to downtime for replacements, further resulting in economic losses. Therefore, a multi-component waste lubricating oil separation device with combined functions is proposed to address these issues. Utility Model Content
[0005] The purpose of this application is to provide a multi-component separation device for waste lubricating oil with combined functions, which aims to improve the problem that some existing multi-component separation devices for waste lubricating oil with combined functions have difficulty vibrating the filter plate.
[0006] This application provides a multi-component separation device for waste lubricating oil with combined functions, which adopts the following technical solution: A multi-component waste lubricating oil separation device with combined functions includes a support plate, multiple support columns fixedly connected to the bottom of the support plate, a base fixedly connected to the bottom of the multiple support columns, a storage tank fixedly connected to the top left of the support plate, a stirring mechanism installed on the top of the storage tank, a discharge pipe one fixedly connected to the right side of the storage tank, a pump fixedly connected to the bottom of the discharge pipe one, a collection box fixedly connected to the right side of the pump, a filter mechanism installed on the front side of the collection box, a discharge pipe two fixedly connected to the right side of the collection box, a heating mechanism installed at the bottom of the storage tank, and a valve installed inside the discharge pipe two. The filtration mechanism includes a second motor, the rear of which is fixedly connected to the front of the collection box. A rotating shaft is fixedly connected to the drive end of the second motor. Semicircular plates are fixedly connected to both the front and rear sides of the rotating shaft. A filter plate is slidably connected to the inner wall of the collection box. Multiple telescopic components are fixedly connected inside the collection box. Each telescopic component includes a fixed box, the outside of which is fixedly connected to the inside of the collection box. A sliding block is slidably connected inside the fixed box. A spring is fixedly connected to the bottom of the sliding block, and the bottom of the spring is fixedly connected to the bottom inner wall of the fixed box. The heating mechanism includes two fixed support plates. The top of the fixed support plate is fixedly connected to the front and rear sides of the bottom of the storage tank. A gear is rotatably connected inside the fixed support plate. A rack is slidably connected inside the fixed support plate. A spring is fixedly connected to one end of the rack. A rack is slidably connected inside the fixed support plate. A heating plate is detachably connected to the bottom of the storage tank. Semicircular blocks are fixedly connected to the front and rear sides of the heating plate. The outer teeth of the rack are meshed with the outer teeth of the gear. The outer teeth of the rack are meshed with the outer teeth of the gear. The outer side of the rack is engaged with the inner side of the semicircular block. The two springs are fixedly connected to the inner wall of the fixed support plate on their adjacent sides. Through the above technical solution: Motor 2 serves as the power source, driving the rotating shaft to rotate the semi-circular plate. The semi-circular plate periodically squeezes the filter plate, causing it to vibrate. The telescopic component provides buffering and resetting, preventing the filter plate from being clogged by impurities, effectively improving filtration efficiency, and achieving efficient solid-liquid separation of waste lubricating oil in the collection box. The fixed box provides a sliding track for the sliding block. The sliding block cooperates with spring 1. When the filter plate is squeezed and vibrated by the semi-circular plate, spring 1 buffers the impact force to prevent damage to the filter plate. After the semi-circular plate stops squeezing, spring 1 pushes the sliding block to reset the filter plate, maintaining a stable vibration frequency of the filter plate and ensuring continuous and efficient filtration. The fixed support plate provides mounting support for components such as gears and racks, and the heating plate can heat the stored material. Heating the oil inside the tank reduces its viscosity, facilitating separation. The engagement of rack one, gear, and rack two, along with the semi-circular block, enables convenient installation and removal of the heating plate, simplifying equipment maintenance. Utilizing the meshing transmission principle of gears and racks, the linear motion of rack one is converted into the rotational motion of the gear, which then drives rack two to produce linear motion, achieving force transmission and changing the direction of motion. This allows for precise control of the engagement and disengagement of rack two with the semi-circular block on the heating plate. When rack two is engaged with the semi-circular block, the heating plate is secured. Pressing rack one disengages rack two from the semi-circular block via gear transmission, allowing the heating plate to be removed. Spring two provides cushioning during rack one's movement and resets rack one when no force is applied, ensuring a stable installation of the heating plate.
[0007] Preferably, the stirring mechanism includes a motor, the bottom of which is fixedly connected to the top of the storage tank, a rotating rod is fixedly connected to the drive end of the motor, and a spiral stirring blade is fixedly connected to the outside of the rotating rod. The above technical solution involves a motor outputting a stable torque to drive a rotating rod, which in turn drives a spiral stirring blade to rotate. The blades agitate the oil, thoroughly mixing it, dispersing impurities, reducing oil unevenness, and improving oil fluidity. This, combined with a heating mechanism, reduces viscosity.
[0008] Preferably, the bottom of the rotating rod is rotatably connected to the inner wall of the bottom of the storage tank, and the outside of the rotating shaft is rotatably connected to the inner wall of the collection box; The above technical solution involves: the bottom of the rotating rod being rotatably connected to the inner wall of the bottom of the storage tank, which keeps the spiral stirring blades stable during stirring and prevents shaking from affecting the stirring effect; and the rotating shaft being rotatably connected to the inner wall of the collection box, which ensures that the semi-circular plate rotates smoothly during the vibration of the filter plate.
[0009] Preferably, the bottom of the second motor is fixedly connected to the top of the support plate, and the outside of the semi-circular plate is in contact with the top of the filter plate.
[0010] The above technical solution involves the semicircular plate contacting the top of the filter plate, which effectively squeezes the filter plate when the semicircular plate rotates, causing it to vibrate up and down. This, combined with the telescopic component, prevents the filter plate from clogging, thus achieving efficient filtration and separation of waste lubricating oil in the collection box.
[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the second motor drives the rotating shaft to rotate the semi-circular plate. The semi-circular plate periodically squeezes the filter plate, causing it to vibrate up and down with the cooperation of the telescopic component. This vibration of the filter plate effectively prevents impurities from accumulating on the filter plate, avoids excessive cleaning due to clogging, reduces physical damage to the filter plate, and allows the filter plate to maintain good filtration performance for a longer period of time. This reduces the frequency of filter plate replacement, saves equipment maintenance costs and downtime required for filter plate replacement. 2. In this utility model, pressing rack one causes rack one to move spring two, which in turn drives gear one to rotate. Through gear transmission, rack two disengages from the semicircular block, thus disassembling the heating plate. This eliminates the need for complex disassembly of the entire separation device. The heating plate can be directly removed for quick component replacement, significantly reducing downtime for maintenance, minimizing production stoppages caused by equipment failures, and ensuring the continuity of waste lubricating oil treatment.

[0013] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0014] Example: A multi-component separation device for waste lubricating oil with combined functions, referring to... Figures 1 to 3 The device includes a support plate 1, with multiple support columns 2 fixedly connected to the bottom of the support plate 1. The bottom of the multiple support columns 2 is fixedly connected to a base 3, which is in direct contact with the ground, providing stable support for the entire device, dispersing the force generated during device operation, and preventing the device from shifting or tilting during operation. A storage tank 4 is fixedly connected to the top left side of the support plate 1. The storage tank 4 is used to store waste lubricating oil to be processed. Its large volume can meet the temporary storage needs of a certain amount of oil. A stirring mechanism 5 is installed on the top of the storage tank 4. Specifically, the support column 2 connects the support plate 1 and the base 3, evenly transferring the weight of the upper part of the device to the base 3, ensuring that the device stands stably on the ground and enhancing its seismic resistance; the support plate 1 serves as a basic bearing platform, providing an installation position for the storage tank 4 and the stirring mechanism 5, ensuring that each component is at a suitable height; the storage tank 4 stores the waste lubricating oil to be treated, providing space for the stirring pretreatment; the motor 51 in the stirring mechanism 5 drives the rotating rod 52 and the spiral stirring blade 53 to rotate, fully stirring the oil in the tank, dispersing impurities, and making the oil evenly mixed, thus realizing the stable storage and preliminary mixing and dispersion treatment of waste lubricating oil in the device.
[0015] A discharge pipe 6 is fixedly connected to the right side of the storage tank 4. The discharge pipe 6 connects the storage tank 4 and the pump 7, and is the channel for transporting waste lubricating oil from the storage tank 4 to the collection box 8. This ensures that the oil can flow smoothly out of the storage tank 4 under the action of the pump 7. The bottom of the discharge pipe 6 is fixedly connected to the pump 7. The right side of the pump 7 is fixedly connected to the collection box 8. The pump 7 provides power for the oil transportation. It generates suction through its own operation to extract the waste lubricating oil that has been pretreated by stirring from the storage tank 4 and pressurize it through the discharge pipe 6 to the collection box 8. A filter mechanism 9 is installed on the front side of the collection box 8. The collection box 8 receives the waste lubricating oil transported by the pump 7 and provides space for the filtration and sedimentation separation process. Its internal structure is compatible with the filter mechanism 9. A second discharge pipe 10 is fixedly connected to the right side of the collection box 8. A heating mechanism 11 is installed at the bottom of the storage tank 4. A valve 12 is installed inside the second discharge pipe 10. Specifically, discharge pipe 1 6 connects storage tank 4 and pump 7, creating a dedicated channel for oil transportation. This allows the waste lubricating oil, after pretreatment by stirring, to flow precisely to collection box 8 under the suction and pressure of pump 7. Pump 7 serves as the power core, ensuring efficient and continuous oil transportation. Collection box 8 receives the oil and works in conjunction with filtration mechanism 9 to filter impurities and separate sediment. Discharge pipe 2 10 connects collection box 8 to subsequent processing stages, and works with valve 12 to precisely control the discharge flow of purified oil. Heating mechanism 11 heats the bottom of storage tank 4 to reduce oil viscosity.
[0016] Reference Figure 2 and Figure 3 The filtration mechanism 9 includes a second motor 91, the rear side of which is fixedly connected to the front side of the collection box 8. The drive end of the second motor 91 is fixedly connected to a rotating shaft 92. Semicircular plates 93 are fixedly connected to the front and rear sides of the rotating shaft 92. The semicircular plates 93 rotate under the drive of the rotating shaft 92, periodically squeezing the filter plate 94 to make it vibrate up and down, thereby improving the filtration efficiency. The filter plate 94 is slidably connected to the inner wall of the collection box 8. The second motor 91 provides power to the filtration mechanism 9, drives the rotating shaft 92 to rotate, and drives the semicircular plates 93 to move, providing a power source for the vibration of the filter plate 94, ensuring that the filter plate 94 can vibrate continuously during the filtration process. The rotating shaft 92 connects the second motor 91 and the semicircular plates 93, transmitting the rotational power of the second motor 91 to the semicircular plates 93. At the same time, it rotates stably on the inner wall of the collection box 8, ensuring the stability of the movement of the semicircular plates 93. The filter plate 94 filters the waste lubricating oil entering the collection box 8, intercepting impurities in the oil, and allowing the preliminarily purified oil to enter the lower part of the collection box 8 through the plate holes. Specifically, the second mechanism 91 acts as the power core, driving the rotating shaft 92 to rotate. The rotating shaft 92 drives the semi-circular plate 93 to rotate stably. The semi-circular plate 93 causes the filter plate 94 to vibrate up and down on the inner wall of the collection box 8 through periodic compression. In conjunction with the filter plate 94, impurities in the waste lubricating oil are intercepted. The slider 95 slides in the fixed box 96, and the spring 97 provides buffering and restoring force, effectively preventing impurities from clogging the filter plate 94. This allows the initially purified oil to smoothly pass through the plate holes and enter the lower part of the collection box 8, realizing efficient solid-liquid separation of waste lubricating oil in the collection box 8, and improving filtration efficiency and separation quality.
[0017] Multiple telescopic components are fixedly connected inside the collection box 8. The telescopic components include a fixed box 96, the outside of which is fixedly connected to the inside of the collection box 8. A sliding block 95 is slidably connected inside the fixed box 96. A spring 97 is fixedly connected to the bottom of the sliding block 95. The spring 97 provides elastic force when the sliding block 95 slides, which plays a buffering role. At the same time, when the semicircular plate 93 stops pressing the filter plate 94, it provides a reset force for the filter plate 94 and maintains the normal vibration frequency of the filter plate 94. The bottom of the spring 97 is fixedly connected to the bottom inner wall of the fixed box 96. The outside of the rotating shaft 92 is rotatably connected to the inner wall of the collection box 8. The bottom of the motor 91 is fixedly connected to the top of the support plate 1. The outside of the semicircular plate 93 is in contact with the top of the filter plate 94. Specifically, multiple telescopic components inside the collection box 8 are securely installed via a fixed box 96, providing a sliding track for the sliding block 95. The sliding block 95 cooperates with the spring 97. When the semicircular plate 93 squeezes the filter plate 94 to make it vibrate, the spring 97 generates an elastic force to buffer the impact force on the filter plate 94, preventing it from being damaged by rigid collision. When the semicircular plate 93 stops squeezing, the spring 97 pushes the sliding block 95 to reset the filter plate 94 by the reset force, ensuring that the filter plate 94 maintains a stable vibration frequency, continuously and efficiently intercepting impurities in the waste lubricating oil, and realizing stable and efficient solid-liquid separation of oil in the collection box 8.
[0018] Reference Figure 4 The stirring mechanism 5 includes a motor 51, the bottom of which is fixedly connected to the top of the storage tank 4. A rotating rod 52 is fixedly connected to the drive end of the motor 51. The motor 51 serves as the power source for the stirring mechanism 5, driving the rotating rod 52 to rotate by outputting a stable torque, thus providing power for oil stirring. The rotating rod 52 connects the motor 51 to the spiral stirring blade 53, transmitting the rotational power of the motor 51 to the spiral stirring blade 53. At the same time, it rotates stably within the storage tank 4. The spiral stirring blade 53 is fixedly connected to the outside of the rotating rod 52. The spiral stirring blade 53 rotates under the drive of the rotating rod 52, stirring the waste lubricating oil in the storage tank 4. The stirring of the blades ensures that the oil is fully mixed and impurities are dispersed. The bottom of the rotating rod 52 is rotatably connected to the bottom inner wall of the storage tank 4.
[0019] Specifically, in the stirring mechanism 5, the motor 51 outputs a stable torque to drive the rotating rod 52. The rotating rod 52 accurately transmits the power to the spiral stirring blade 53, causing it to rotate stably in the storage tank 4. The spiral stirring blade 53, through the stirring of the blades, makes the waste lubricating oil fully mixed, effectively disperses impurities, reduces the unevenness of the oil, and at the same time improves the fluidity of the oil through stirring, and reduces the viscosity of the oil in conjunction with the heating mechanism.
[0020] Reference Figure 2 and Figure 5 The heating mechanism 11 includes two fixed support plates 111. The tops of the two fixed support plates 111 are fixedly connected to the front and rear sides of the bottom of the storage tank 4. Gears 112 are rotatably connected inside the fixed support plates 111. The gears 112 rotate under the transmission of rack 113 and rack 215, so that rack 215 can engage or disengage with the semicircular block 117. Rack 113 is slidably connected inside the fixed support plates 111. A spring 214 is fixedly connected to one end of rack 113. Rack 215 is slidably connected inside the fixed support plates 111. When rack 113 is pressed, it drives spring 214 to move. Through the meshing transmission with gear 112, it moves its own linear motion. The motion is converted into the rotational motion of gear 112, which in turn controls the action of rack 115. A heating plate 116 is detachably connected to the bottom of storage tank 4. Semicircular blocks 117 are fixedly connected to both the front and rear sides of heating plate 116. Heating plate 116 heats the waste lubricating oil at the bottom of storage tank 4, increases the oil temperature, reduces the oil viscosity, and makes it easier to separate the components in the oil. The outer teeth of rack 115 are meshed with the outer teeth of gear 112. The outer teeth of rack 113 are meshed with the outer teeth of gear 112. The outer side of rack 115 is engaged with the inner side of semicircular block 117. The two springs 114 are fixedly connected to the inner wall of fixed support plate 111 on the side closest to each other. Specifically, in the heating mechanism 11, two fixed support plates 111 form a stable mounting frame for gear 112, rack one 113, and rack two 115. When rack one 113 is pressed, it drives spring two 114 to move and, through meshing with gear 112, converts linear motion into rotational motion of gear 112. Gear 112 then drives rack two 115 to produce linear motion, achieving engagement or disengagement with the semi-circular blocks 117 on both sides of heating plate 116, facilitating the quick disassembly and installation of heating plate 116. When heating plate 116 is working, it effectively reduces the viscosity of the oil by heating the waste lubricating oil at the bottom of storage tank 4, making it easier for the components to separate. Spring two 114 provides buffering and restoring force when rack one 113 moves.
[0021] Working principle: The waste lubricating oil to be processed is injected into the storage tank 4. The motor 51 drives the rotating rod 52 and the spiral stirring blade 53 to rotate, which fully stirs the oil in the tank, so that the oil is evenly mixed and impurities are initially dispersed. The heating plate 116 of the heating mechanism 11 heats the bottom of the storage tank 4, raising the oil temperature to reduce its viscosity, which facilitates subsequent separation operations.
[0022] The pump 7 delivers the pretreated oil to the collection box 8 through the discharge pipe 6. The motor 91 drives the rotating shaft 92 to rotate the semi-circular plate 93. The semi-circular plate 93 periodically squeezes the filter plate 94, causing it to vibrate up and down with the cooperation of the telescopic component. In the telescopic component, the sliding block 95 slides in the fixed box 96, and the spring 97 provides buffering and restoring force. The vibration effectively prevents impurities from clogging the filter plate 94 and improves the filtration efficiency.
[0023] The filtered oil undergoes further sedimentation and separation in the collection tank 8. Impurities are trapped above the filter plate 94. The preliminarily purified oil is discharged through the discharge pipe 10. The discharge flow rate is controlled by the valve 12 and can be adjusted according to the processing progress and oil characteristics to ensure the separation effect.
[0024] When the heating plate 116 needs to be replaced or cleaned, press the rack 113. After the rack 113 drives the spring 2 114 to move, the rack 113 drives the gear 112 to rotate. Through the transmission of the gear 112, the rack 2 115 disengages from the semi-circular block 117, and the heating plate 116 can be quickly removed for convenient maintenance.
