Description

Technical Field

[0001] This invention belongs to the field of resource recycling technology, specifically relating to a waste lubricating oil collection and treatment device. Background Technology

[0002] Waste lubricating oil refers to various types of lubricating oil that have lost their original lubricating function due to performance degradation during use and have been replaced. The classification of waste lubricating oil is mainly based on the type of oil and the degree of pollution, with the core purpose of grouping waste oils with similar properties and compatible treatment processes into one category.

[0003] In existing technologies, waste lubricating oil recycling typically involves on-site personnel verifying that the waste oil type matches the container label and checking for contamination with mud, sand, and debris. Different types of waste oil are then separated and loaded into dedicated open-top containers or troughs. However, during transport, vehicle movement can cause mixing of different types of waste oil. A common solution is to use a non-open structure, such as a sealed cap at the opening. However, this method requires repeated opening and sealing steps for filling and removing waste oil, resulting in low efficiency, increased labor costs, poor adaptability, and limited practicality. Summary of the Invention

This design offers good adaptability and practicality. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0021] Please refer to the following: Figures 1 to 5 The waste lubricating oil collection and treatment device provided by the present invention will now be described. The waste lubricating oil collection and treatment device includes a filter barrel 10, a dispensing mechanism 20, and dispensing barrels 30. The filter barrel 10 has a filter chamber 11 at its top and a feed inlet communicating with the filter chamber 11 at its top. The filter barrel 10 has a supporting chamber 12 at its bottom, and a rotary drive structure 13 is provided at the bottom end of the supporting chamber 12. A discharge port is provided between the filter chamber 11 and the supporting chamber 12. The discharge port is spaced apart from the axis of the rotary drive structure 13. The dispensing mechanism 20 is located at the discharge port. Multiple dispensing barrels 30 are provided, each dispensing barrel 30 is mounted on the rotary drive structure 13, and they are arranged annularly spaced around the axis of the rotary drive structure 13. Each dispensing barrel 30 has a feed structure 33 at its top that corresponds to the dispensing mechanism 20.

[0022] Each dispensing barrel 30 rotates as driven by the rotary drive structure 13, and each dispensing barrel 30 corresponds to and is connected to the dispensing mechanism 20 in sequence.

[0023] The waste lubricating oil collection and processing device provided in this embodiment, compared with the prior art, realizes integrated automated operation of waste lubricating oil filtration and dispensing, fundamentally solving the problem of low efficiency of manual dispensing in the prior art. Through the rotary drive structure 13, multiple dispensing barrels 30 are sequentially docked with the dispensing mechanism 20, enabling continuous dispensing of the filtered waste lubricating oil, significantly increasing the processing capacity. The discharge port is spaced apart from the axis of the rotary drive structure 13, and the dispensing barrels 30 are arranged in a ring, ensuring that each dispensing barrel 30 accurately corresponds to the dispensing mechanism 20, avoiding docking deviations that may occur during manual operation. At the same time, this structural design eliminates the need for repeated manual handling and container replacement, reducing labor costs. Furthermore, the entire process, from filtration to dispensing, takes place in a relatively closed environment, reducing the chance of contact with the outside world, minimizing the risk of secondary contamination by impurities, and avoiding the leakage problems that may occur when dispensing open containers before transportation. It has good adaptability and practicality.

[0024] The rotary drive structure 13 can be replaced with a ring conveyor belt structure, with the dispensing barrels 30 fixed on the conveyor belt. The sequential docking of the dispensing barrels 30 with the dispensing mechanism 20 is achieved through the cyclical movement of the conveyor belt. The arrangement of the dispensing barrels 30 can also be changed to a linear arrangement, which, together with a linear drive mechanism (such as a cylinder-driven slider), drives the dispensing barrels 30 to move, thus achieving the same sequential docking function.

[0025] In some embodiments, the filter cartridge 10 may be as follows: Figures 1 to 3 The structure shown. See also Figures 1 to 3 The filter barrel 10 includes a first barrel body 14, a first cover 15, a filter frame 16, a second barrel body 17, and a second cover 18. The first barrel body 14 has a filter chamber 11 with an open top and a discharge port at the bottom. The first cover 15 covers the open top of the first barrel body 14 and has a feed inlet. The filter frame 16 is disposed within the filter chamber 11, with a filter inlet at the top and a filter outlet at the bottom, and has multiple filter positions spaced vertically. The second barrel body 17 has a bearing chamber 12 with an open top. The second cover 18 covers the open top of the second barrel body 17 and has a feed outlet communicating with the discharge port.

[0026] The first barrel 14 and the second barrel 17 are independent of each other, allowing for separate maintenance and cleaning of the filter chamber 11 and the carrying chamber 12 without interference. When cleaning the filter chamber 11 or replacing filter components is required, there is no need to operate the rotary drive structure 13 and the dispensing barrel 30 within the carrying chamber 12, greatly simplifying the maintenance process. The first cover 15 and the second cover 18 not only facilitate the opening of the filter chamber 11 and the carrying chamber 12, making it easier to install and repair internal components, but also effectively prevent external dust and debris from entering the chambers, ensuring a clean environment for waste lubricating oil treatment. The multiple filtration positions of the filter frame 16 achieve multi-stage filtration of waste lubricating oil, which can more thoroughly remove impurities of different sizes compared to single-stage filtration, improving the filtration effect and solving the problem of incomplete waste oil filtration affecting subsequent treatment in existing technologies. The feed port ensures that the filtered waste lubricating oil can accurately enter the dispensing mechanism 20, avoiding waste and pollution caused by oil leakage.

[0027] The filter chamber 11 and the carrying chamber 12 can adopt an integrally formed barrel structure, separated by an internal partition, on which a discharge port and a flow port are provided. The filter position of the filter frame 16 can adopt an inclined filter plate 162 to change the flow path of waste lubricating oil, extend the filtration time, and improve the filtration efficiency.

[0028] In some embodiments, the filter holder 16 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The filter frame 16 includes a support frame 161 and filter plates 162. The support frame 161 is disposed inside the filter chamber 11, with an open filter inlet at the top and a filter outlet at the bottom. Multiple filter plates 162 are provided, and each filter plate 162 is arranged vertically at intervals on the support frame 161.

[0029] The support frame 161 provides a stable mounting base for the filter plates 162, ensuring that the filter plates 162 will not shift or deform under the impact of waste lubricating oil, thus guaranteeing the stability of the filtration process. Multiple filter plates 162 are arranged at vertical intervals, forming a stepped filtration channel. Waste lubricating oil flows sequentially through each filter plate 162 under gravity, gradually removing impurities. The upper filter plates 162 filter larger particles, while the lower filter plates 162 filter smaller particles. This graded filtration method is more thorough than using a single filter plate 162, significantly improving the purity of the waste lubricating oil. The spacing of the filter plates 162 also facilitates observation of clogging, allowing for timely cleaning or replacement and preventing clogging from affecting filtration efficiency.

[0030] The filter holder 16 can adopt a drawer-type structure, with the filter plate 162 installed inside the drawer. When cleaning or replacing the filter plate 162 is required, simply pull out the drawer for easier operation. The filter plate 162 can be replaced with a filter membrane. Different precision filter membranes can be selected according to the impurities in the waste lubricating oil to improve the targeting of filtration.

[0031] In some embodiments, the dispensing mechanism 20 described above may employ, for example... Figure 4 The structure shown. See also Figure 4 The dispensing mechanism 20 includes a sliding nozzle 21, a limiting cap 22, a first sealing bead 23, and a tension spring 24. The sliding nozzle 21 is vertically slidably disposed at the outlet of the first barrel 14, and has a hollow discharge cavity. The limiting cap 22 is fastened to the top of the sliding nozzle 21, with one end extending into the discharge cavity. The limiting cap 22 has a through-hole that runs vertically through the limiting cap 22 and communicates with the discharge cavity. The first sealing bead 23 is disposed within the discharge cavity. The tension spring 24 is sleeved on the sliding nozzle 21, with one end connected to the sliding nozzle 21 and the other end connected to the first barrel 14. The tension spring 24 is used to ensure that the sliding nozzle 21 always moves vertically.

[0032] The sliding nozzle 21 can slide vertically. When docking with the feeding structure 33 of the dispensing tank 30, its height can be automatically adjusted according to the position of the feeding structure 33 to ensure a tight docking. The limiting cap 22 not only limits the movement of the sliding nozzle 21, but its through-hole also ensures that waste lubricating oil can smoothly enter the discharge cylinder cavity. In the non-docked state, the first sealing bead 23 can seal the discharge cylinder cavity by its own weight and the pressure of the waste lubricating oil to prevent oil leakage. When docking with the feeding structure 33, the first sealing bead 23 is lifted by external force, and the oil flows out smoothly. The tension spring 24 provides continuous tension to the sliding nozzle 21. After docking, it can drive the sliding nozzle 21 to quickly reset, so that the first sealing bead 23 re-seals the discharge cylinder cavity, avoiding the problem of oil dripping when switching dispensing tanks 30. This structure eliminates the need for manual operation of the sealing components, reduces labor costs, improves the reliability of the seal, and solves the problem of cumbersome operation of the sealing cap in the prior art.

[0033] The tension spring 24 can be replaced by a compression spring 333, which is installed above the sliding nozzle 21. The spring force of the spring 333 pushes the sliding nozzle 21 downward, thus achieving the same reset function of the sliding nozzle 21. The first sealing bead 23 can be replaced by a sealing piston. The sealing piston fits tightly with the inner wall of the discharge cylinder cavity, and the opening and closing of the discharge cylinder cavity is achieved by the up and down movement of the piston.

[0034] In some embodiments, the rotary drive structure 13 described above can be as follows: Figure 2 , Figure 3The structure shown. See also Figure 2 , Figure 3 The rotary drive structure 13 includes a rotating shaft 131, a rotating disk 132, and a driver 133. The rotating shaft 131 is disposed within the bearing cavity 12. Its top end is rotatably connected to the second cover 18, and its bottom end is rotatably connected to the second barrel 17. The rotation axis of the rotating shaft 131 is coaxial with the central axis of the second barrel 17. The rotating disk 132 is fixed to the rotating shaft 131, and its axis is collinear with the axis of the rotating shaft 131. The driver 133 drives the rotating shaft 131 to rotate.

[0035] The rotating connection between the rotating shaft 131 and the second cover 18 and the second barrel 17 ensures that the rotating shaft 131 will not deviate during rotation, providing stable support for the rotating disk 132. The rotating disk 132 and the rotating shaft 131 are collinear, allowing the dispensing barrels 30 on the rotating disk 132 to rotate uniformly around the same axis, ensuring the positional accuracy of each dispensing barrel 30 when docking with the dispensing mechanism 20. The driver 133 provides a stable driving force and can adjust the rotation speed and angle according to actual needs to achieve precise positioning of the dispensing barrels 30. This structure can drive multiple dispensing barrels 30 to rotate in an orderly manner, achieving continuous dispensing, avoiding the tedious manual handling of the dispensing barrels 30, and improving dispensing efficiency. Simultaneously, the enclosed environment within the bearing cavity 12 protects the rotary drive structure 13, reducing the corrosion of components by external dust and moisture, and extending the service life of the equipment.

[0036] In some embodiments, the dispensing drum 30 may be adopted as follows: Figures 2 to 4 The structure shown. See also Figures 2 to 4 Each dispensing container 30 includes a third container body 31, a third cover 32, and a feeding structure 33. The third container body 31 is detachably connected to the rotating disk 132 and has a dispensing cavity with an open top. The third cover 32 is detachably connected to the open part of the third container body 31 and has a material outlet at its top. The feeding structure 33 is located at the material outlet of the corresponding third cover 32 and is used to connect to the sliding nozzle 21 when the corresponding material outlet moves below the sliding nozzle 21.

[0037] The detachable connection between the third barrel 31 and the rotating disk 132 allows for easy removal of the dispensing barrel 30 from the rotating disk 132 for transportation or replacement once it is full. This simple and quick operation solves the problem of inconvenient handling of existing reusable barrels. The detachable connection between the third cover 32 and the third barrel 31 facilitates opening the dispensing chamber for cleaning or maintenance, ensuring its cleanliness. The feeding structure 33 automatically connects with the dispensing mechanism 20. When oiling is not required, the feeding structure 33 is sealed to prevent leakage of waste lubricating oil or mixing with other types of waste oil during transportation. When oiling is required, it accurately connects with the dispensing mechanism 20, ensuring smooth entry of oil into the dispensing chamber. This structural design allows the dispensing barrel 30 to be sealed and preserved throughout the process while also enabling convenient oiling operations, overcoming the drawbacks of repeated opening and closing of existing sealed covers and improving practicality.

[0038] The connection between the third barrel 31 and the rotating disk 132 can be replaced by a magnetic connection. A magnet is installed on the rotating disk 132, and an iron plate is installed at the bottom of the third barrel 31. The magnetic force enables a detachable connection, making operation more convenient. The third cover 32 and the third barrel 31 can be connected by a snap-fit, which is faster to open and close than a threaded connection.

[0039] In some embodiments, the above-described feeding structure 33 may employ, as follows: Figure 4 The structure shown. See also Figure 4 The feeding structure 33 includes a feeding cylinder 331, a second sealing bead 332, and a spring 333. The feeding cylinder 331 is located at the feed inlet and is integrally connected to it. The feeding cylinder 331 has a feed chamber with an open top, and a feed hole communicating with the feed chamber is provided on the side wall of the feeding cylinder 331. The second sealing bead 332 is located inside the feed chamber. The spring 333 is located inside the feed chamber, with its bottom end connected to the feeding cylinder 331 and its top end abutting against the second sealing bead 332. The spring 333 is used to ensure that the second sealing bead 332 always tends to move upwards in the vertical direction, thereby sealing the openness of the feed chamber.

[0040] The feeding structure 33 achieves automatic sealing and connection of the dispensing barrel 30, providing excellent sealing performance. In the non-oil-filled state, the second sealing bead 332 moves upward under the action of the spring 333, sealing the opening of the material flow chamber. This effectively prevents leakage of waste lubricating oil in the dispensing chamber due to shaking during transportation or rotation, avoiding the problem of mixing different types of waste oil. When docking with the dispensing mechanism 20, the sliding nozzle 21 pushes the second sealing bead 332 downward, compressing the spring 333 and opening the material flow chamber. Waste lubricating oil enters the dispensing chamber through the material flow chamber and the material flow hole, achieving automatic connection. The material flow hole is located on the side wall of the feeding cylinder 331, ensuring that the oil can flow smoothly into the dispensing chamber and preventing oil accumulation in the material flow chamber. The stable elasticity of the spring 333 ensures the long-term sealing effect of the second sealing bead 332. This structure eliminates the need for manual operation of the sealing components, improving operational convenience and sealing reliability, and solving the problems of cumbersome operation and poor sealing effect of the sealing cap in existing technologies.

[0041] The second sealing bead 332 can be replaced with a silicone sealing ring. The sealing ring is fixed at the opening of the material feeding chamber. When it is connected with the sliding nozzle 21, the sealing ring is squeezed and deformed to achieve a seal. When separated, it relies on its own elasticity to restore the sealing state.

[0042] In some embodiments, the third cover 32 may be adopted as follows: Figures 2 to 5 The structure shown. See also Figures 2 to 5 The top of the third cover 32 is provided with a conical surface, and the bottom of the second cover 18 is provided with a sliding groove that matches the conical surface.

[0043] The conical surface at the top of the third cover 32 matches the groove at the bottom of the second cover 18, providing excellent guidance and limiting during the rotation of the dispensing barrel 30. The conical surface guides the dispensing barrel 30 accurately into the groove, ensuring that it does not shift laterally during rotation and guaranteeing the precision of the connection between the feeding structure 33 and the dispensing mechanism 20. The constraint of the groove on the conical surface reduces the shaking of the dispensing barrel 30 during rotation, making the entire rotation process smoother and preventing waste lubricating oil from splashing out of the dispensing barrel 30 or colliding with other components due to shaking. This structural design improves the stability and reliability of the device operation, extends the service life of the equipment, and also ensures the continuity and efficiency of the dispensing process, solving the problem of component instability during rotation.

[0044] The fit between the conical surface and the groove can be replaced by the fit between a ball bearing and a ring track. A ball bearing is installed at the top of the third cover 32, and a ring track is installed at the bottom of the second cover 18. The ball bearing rolls within the track, achieving the same guiding and limiting function, but with less frictional resistance. Alternatively, a guide rod and a guide sleeve can be installed between the third cover 32 and the second cover 18, with the guide rod sliding within the guide sleeve to achieve limiting.

[0045] In some embodiments, the dispensing drum 30 may be adopted as follows: Figure 3 , Figure 5 The structure shown. See also Figure 3 , Figure 5 Each dispensing container 30 also includes a heating assembly 34, which is disposed within the dispensing cavity. The heating assembly 34 includes a partition cover 341 and a heating rod 342. The partition cover 341 is disposed within the dispensing cavity and has a partition chamber. The heating rod 342 is disposed within the partition chamber.

[0046] The heating component 34 effectively ensures the fluidity of waste lubricating oil within the dispensing chamber, making it particularly suitable for handling waste lubricating oil in low-temperature environments or with high viscosity. The heating rod 342 heats within the partition chamber of the separator 341, transferring heat to the waste lubricating oil through the separator 341. This raises the temperature and lowers the viscosity of the waste lubricating oil, facilitating subsequent transportation and processing. The separator 341 isolates the heating rod 342 from the waste lubricating oil, preventing direct contact, corrosion, or contamination, extending its service life, and ensuring the purity of the waste lubricating oil. The heating component 34 allows for temperature control as needed, ensuring the waste lubricating oil maintains suitable fluidity, solving the problem of increased viscosity and difficulty in processing waste lubricating oil at low temperatures, and improving the device's adaptability to different environments and types of waste lubricating oil.

[0047] The heating element 34 can be replaced with an electromagnetic heating coil, wound around the outside of the third barrel 31, to heat the waste lubricating oil through electromagnetic induction, resulting in higher heating efficiency and eliminating the need for contact with the waste lubricating oil. The partition cover 341 can be made of copper, a material with better thermal conductivity, to improve heat transfer efficiency.

[0048] In some embodiments, the first barrel 14 described above can be adopted as follows: Figure 2 , Figure 3 , Figure 5 The structure shown. See also Figure 2 , Figure 3 , Figure 5 The second barrel 17 is equipped with an insulation layer 171.

[0049] The insulation layer 171 inside the second tank 17 effectively reduces heat loss of the waste lubricating oil in the filter chamber 11, ensuring that the waste lubricating oil maintains a suitable temperature and fluidity during filtration. In cold environments, the insulation layer 171 prevents the viscosity of the waste lubricating oil from increasing due to low temperatures, avoiding slowed filtration speed or clogging of the filter plate 162, and ensuring smooth filtration. For waste lubricating oil requiring heat treatment, the insulation layer 171 reduces heating energy consumption and improves energy efficiency. The insulation layer 171 keeps the temperature inside the filter chamber 11 stable, unaffected by changes in external ambient temperature, ensuring consistent filtration performance and improving the device's adaptability to different environments. This structural design not only facilitates efficient filtration but also reduces operating costs and solves the problem of temperature variations affecting filtration performance.

[0050] Insulation layer 171 can be replaced with vacuum insulation layer 171, which reduces heat transfer by vacuuming and provides better insulation. Foamed insulation materials, such as polyurethane foam, can also be used, which are lightweight and have good insulation performance.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
