Description

Technical Field

[0001] This utility model relates to the field of lubricating oil recovery technology, and more specifically, to a device for recovering liquid lubricating oil. Background Technology

[0002] In modern industrial machinery, liquid lubricating oil is a core medium for ensuring the long-term stable operation of equipment. By forming an oil film on the surface of moving parts, it effectively reduces frictional losses in key components such as production line guides, gear sets, and bearings. It also serves to cool and dissipate heat, and isolate moisture and impurities, directly determining the service life of mechanical parts and the operational accuracy of the equipment. Especially in high-precision component production lines, guides require frequent lubrication based on operating load. In actual use, due to equipment vibration, leakage between components, and gravity, a large amount of residual oil that cannot adhere to the lubrication surface drips from the guide surface, resulting in significant oil loss.

[0003] Existing technologies for recycling lubricating oil in industrial production lines still have two key shortcomings that make it difficult to meet actual production needs: First, there is a lack of protective measures against waste oil splashing. Splashed waste oil can easily fall onto the workpieces below, causing pollution, or even seep into the electrical control box or motor area of ​​the production line, causing safety hazards such as short circuits and component burnout. Second, waste oil cannot be recycled and reused in a timely manner. It needs to be collected in a unified manner and then transported to special equipment for further purification before it can be used. The process is slow and inefficient, and it is impossible to achieve real-time recycling and reuse of waste oil.

[0004] In summary, in order to meet the actual needs of industrial production lines for lubricant recycling, avoid production safety hazards, and improve resource utilization efficiency, it is necessary to solve the problems of waste oil splashing and contaminating workpieces and causing electrical faults, as well as the slow waste oil recycling process and the inability to reuse it in real time. This will enable industrial production line lubricant recycling to not only ensure production safety and product quality, but also achieve efficient closed-loop circulation. Utility Model Content

[0005] The present invention provides a device for recycling liquid lubricating oil, which aims to solve the problems of waste oil splashing and contaminating workpieces and causing electrical faults, as well as the slow waste oil recycling process and the inability to reuse it in real time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for recovering liquid lubricating oil, comprising a base plate, a sedimentation tank, a collection tank, and an oil filling tank fixedly mounted side by side on the base plate, an electromagnetic adsorption plate fixedly mounted at the bottom of the sedimentation tank, a first fixed plate fixedly connected to the sedimentation tank, a filter fixedly connected to the first fixed plate, a vacuum generator fixedly connected to the collection tank, a connecting pipe fixedly connected between the sedimentation tank and the filter inlet, a first conveying pipe fixedly connected between the filter outlet and the vacuum generator inlet, a second conveying pipe fixedly connected between the vacuum generator outlet and the collection tank, a connecting cylinder disposed above the sedimentation tank, an oil collection trough fixedly connected to the connecting cylinder, two extended troughs movably disposed within the oil collection trough, an oil guide pipe fixedly connected between the connecting cylinder and the sedimentation tank, and a connecting cylinder fixedly connected to the inner side of the sedimentation tank. The adsorption output end of the electromagnetic adsorption plate is disposed at the bottom inner side of the sedimentation tank, and its adsorption surface faces upward and is flush with the bottom of the tank.

[0007] In a preferred embodiment, the connecting pipe is positioned at two-thirds of the height of the settling tank, and the liquid level sensor is positioned at three-quarters of the height of the settling tank.

[0008] In a preferred embodiment, a fixing ring is provided on the inner side of the middle part of the oil collecting tank, a filter screen is fixedly connected to the inner side of the fixing ring, and a handle is fixedly connected to the upper end of the fixing ring.

[0009] In a preferred embodiment, multiple sets of corner blocks are fixedly connected to the oil collection tank, with two corner blocks in each set. A fixing rod is fixedly connected between the two corner blocks in each set, and a sliding block is slidably connected to the outside of each fixing rod. Each sliding block is fixedly connected to the corresponding extension groove.

[0010] In a preferred embodiment, two sets of fixing plates are fixedly connected to the sedimentation tank. Each set of fixing plates consists of two plates. A cylinder is installed on each of the two fixing plates in each set. A support plate is fixedly connected to the output end of the cylinder, and both support plates are fixedly connected to the connecting cylinder.

[0011] In a preferred embodiment, a connecting pipe is fixedly connected to the upper end of the sedimentation tank, a sealing cap is provided on the outside of the connecting pipe, and a drain pipe is fixedly connected to one side of the sedimentation tank, with a valve installed on the drain pipe.

[0012] In a preferred embodiment, an oil pump is fixedly installed on the oil tank. The oil inlet and outlet of the oil pump are respectively fixedly connected to an oil inlet pipe and an oil outlet pipe. The end of the oil inlet pipe away from the oil pump is fixedly connected to the lower inner side of the collection tank, and the end of the oil outlet pipe away from the oil pump is fixedly connected to the upper inner side of the oil tank. A valve is installed on the oil inlet pipe.

[0013] In a preferred embodiment, a plurality of brakeable casters are fixedly connected to the bottom of the base plate, and a handle is fixedly connected to the top of the base plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model, by setting up a connecting cylinder, an oil collection tank, and an oil guide pipe, and cooperating with the pushing work of the cylinder, can make the oil collection tank fully cover the bottom of the guide rail according to the width of the guide rail, collect the dripping waste oil, and prevent the waste oil from dripping to the outside. The connected cylinder and the oil guide pipe are used to guide the collected waste oil into the sedimentation tank for collection and treatment. At the same time, the filter screen supported by the fixed ring in the oil collection tank initially intercepts impurities, preventing waste oil carrying impurities from splashing onto the workpiece or seeping into the electrical control box. This not only ensures product quality, but also avoids safety risks such as short circuits and component burnout.

[0016] This invention achieves efficient real-time recycling and reuse of waste oil through an integrated design of "sedimentation and impurity removal - negative pressure filtration - closed-loop reinjection". First, the electromagnetic adsorption plate in the sedimentation tank can quickly adsorb iron impurities. In conjunction with the liquid level sensor and the vacuum generator, when the oil level reaches the standard, the negative pressure accelerates the oil through the connecting pipe and filter into the collection tank, avoiding the long waiting time of traditional natural sedimentation. Second, the clean oil in the collection tank can be directly transported to the oil injection tank through the oil pump, oil inlet pipe and oil outlet pipe. There is no need to collect and transport it to special equipment for processing. The entire recycling process can be completed online, which greatly shortens the waste oil reuse cycle, reduces lubricating oil waste, and lowers enterprise procurement costs, truly realizing the real-time closed-loop recycling of waste oil.

[0017] This invention features an extended groove, which allows the sliding block to move freely along a fixed rod, thereby adjusting the position of the extended groove. This expands the range of waste oil collection in the oil collection tank, better matching the collection of waste oil with guide rails of different sizes. At the same time, it reduces space occupation when retracted, making it efficient and convenient to work with. Attached Figure Description

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual appendix Figures 1 to 5 A device for recovering liquid lubricating oil includes a base plate 1, a sedimentation tank 2, a collection tank 3, and an oil filling tank 4, which are fixedly installed side by side on the base plate 1, an electromagnetic adsorption plate 5 fixedly installed at the bottom of the sedimentation tank 2, a fixing plate 11 fixedly connected to the sedimentation tank 2, a filter 12 fixedly connected to the fixing plate 11, a vacuum generator 13 fixedly connected to the collection tank 3, a connecting pipe 10 fixedly connected between the sedimentation tank 2 and the inlet of the filter 12, a first conveying pipe 14 fixedly connected between the outlet of the filter 12 and the inlet of the vacuum generator 13, a second conveying pipe 15 fixedly connected between the outlet of the vacuum generator 13 and the collection tank 3, a connecting cylinder 6 set above the sedimentation tank 2, an oil collection trough 7 fixedly connected to the connecting cylinder 6, two extended troughs 8 movably set in the oil collection trough 7, an oil guide pipe 9 fixedly connected between the connecting cylinder 6 and the sedimentation tank 2, and a connecting cylinder 6 fixedly connected to the inside of the sedimentation tank 2. The adsorption output end of the electromagnetic adsorption plate 5 is set at the bottom inside the sedimentation tank 2, and its adsorption surface faces upward and is flush with the bottom of the tank.

[0026] It should be noted that the base plate 1 supports the sedimentation tank 2, the collection tank 3, and the oil filling tank 4, forming a closed-loop foundation for "sedimentation-collection-refilling". The electromagnetic adsorption plate 5 is installed at the bottom of the sedimentation tank 2 to adsorb iron impurities. The fixing plate 11 fixes the filter 12, which is composed of porous material. Through its multiple small holes, it can effectively capture tiny particles and impurities in the lubricating oil. The size of these small holes is precisely designed to ensure that it can intercept particles of different sizes, thereby improving the filtration efficiency. The connecting pipe 10, the first conveying pipe 14, and the second conveying pipe 15 work with the vacuum generator 13 to realize the filtration and transportation of oil from the sedimentation tank 2 to the collection tank 3. The oil collection tank 7 receives waste oil through the connecting cylinder 6 and the oil guide pipe 9 and introduces it into the sedimentation tank 2. The extended tank 8 can adjust the oil collection range, and the whole process completes the initial recovery of waste oil.

[0027] Another improved embodiment based on the extended slot 8 design replaces the original sliding extended slot 8 with a "hinged folding extended plate with magnetic blocks". The new structure achieves extension and retraction through multiple sub-plates folded by hinges, and the magnetic blocks are used to fix the position. Compared with the original structure, the absence of sliding gaps avoids impurities getting stuck, the absence of bolt connections prevents oil corrosion and loosening, individual sub-plates can be replaced independently to reduce maintenance costs, and the number of sections can be adjusted to adapt to wider guide rails, improving durability and adaptability.

[0028] Refer to the instruction manual appendix Figure 3 The connecting pipe 10 is positioned at two-thirds of the height of the sedimentation tank 2, and the liquid level sensor 16 is positioned at three-quarters of the height of the sedimentation tank 2.

[0029] It should be noted that the connecting pipe 10 is located at two-thirds of the height of the sedimentation tank 2, and the liquid level sensor 16 is installed at three-quarters of the height. When the oil level reaches this height, the vacuum generator 13 is activated to pump oil, so that the connection between the filter 12 and the sedimentation tank 2 is negative, which accelerates the flow of liquid into the filter 12. When the oil level drops to two-thirds of the height, it is turned off to avoid air intake and at the same time ensure the adsorption effect of the electromagnetic adsorption plate 5.

[0030] Refer to the instruction manual appendix Figure 4 and Figure 5 A fixing ring 17 is provided on the inner side of the middle part of the oil collection tank 7. A filter screen 18 is fixedly connected to the inner side of the fixing ring 17, and a handle 19 is fixedly connected to the upper end of the fixing ring 17.

[0031] It should be noted that the fixing ring 17 in the oil collection tank 7 supports the filter screen 18, which initially intercepts large impurities and reduces the burden of subsequent processing. The handle 19 on the fixing ring 17 makes it easy to remove the filter screen 18 for cleaning and replacement.

[0032] Refer to the instruction manual appendix Figure 4Multiple sets of corner blocks 20 are fixedly connected to the oil collection tank 7. Each set of corner blocks 20 consists of two blocks. A fixing rod 21 is fixedly connected between the two corner blocks 20 in each set. A sliding block 22 is slidably connected to the outside of each fixing rod 21, and each sliding block 22 is fixedly connected to the corresponding extension groove 8.

[0033] It should be noted that the corner block 20 of the oil collection tank 7 is fixed to the fixing rod 21, and the sliding block 22 slides along the rod and connects to the extension groove 8. Pulling the extension groove 8 can adapt to guide rails of different widths to avoid waste oil leakage; pushing it back reduces the footprint and improves space utilization.

[0034] Refer to the instruction manual appendix Figure 1 Two sets of fixing plates 23 are fixedly connected to the sedimentation tank 2. Each set of fixing plates 23 consists of two plates. A cylinder 24 is installed on each of the two fixing plates 23 in each set. A support plate 25 is fixedly connected to the output end of the cylinder 24, and both support plates 25 are fixedly connected to the connecting cylinder 6.

[0035] It should be noted that the cylinder 24 is installed on the fixing plate 23 of the sedimentation tank 2. The cylinder 24 is connected to the connecting cylinder 6 through the support plate 25. The extension and retraction of the cylinder 24 can adjust the height of the oil collection tank 7 so that it is at a suitable height from the guide rail for operation.

[0036] Refer to the instruction manual appendix Figure 1 and Figure 2 A connecting pipe 26 is fixedly connected to the upper end of the sedimentation tank 2, and a sealing cap 27 is provided on the outside of the connecting pipe 26. A drain pipe 28 is fixedly connected to one side of the sedimentation tank 2, and a valve 29 is installed on the drain pipe 28.

[0037] It should be noted that the upper connecting pipe 26 of the sedimentation tank 2 is equipped with a sealing cap 27 to maintain the internal sealing effect. When it is necessary to deal with the thick iron filings adsorbed on the internal electromagnetic adsorption plate 5, part of the collected lubricating oil can be sucked away by the vacuum generator 13 first. The remaining lubricating oil can be discharged by opening the valve 29 and draining the drain pipe 28. Then, the power supply of the electromagnetic adsorption plate 5 is turned off, and the adsorbed iron filings will naturally loosen. Then, the adsorption tube of the external adsorption device is inserted from the connecting pipe 26, and the adsorption tube is used to suck out the iron filings inside. After cleaning the iron filings, the strong adsorption effect of the electromagnetic adsorption plate 5 on iron filings can be maintained.

[0038] Another improved embodiment based on the design of connecting pipe 26, sealing cap 27, drain pipe 28, and valve 29 adds a self-cleaning scraping mechanism to the sedimentation tank 2, consisting of "guide rail + PTFE scraper + micro electric push rod + inclined slag collection trough + filter screen added inside drain pipe 28". This replaces the original external adsorption cleaning method. The new structure does not require draining the oil. After the electromagnetic adsorption plate 5 is closed, the electric push rod pushes the scraper to move along the guide rail, scraping impurities into the slag collection trough, which is then separated and discharged through the filter screen in drain pipe 28. Compared with the original structure, the operation time is shortened, the impurity removal rate is increased, oil waste and manual intervention are avoided, and automatic cleaning can be performed at regular intervals, improving cleaning efficiency and convenience.

[0039] Refer to the instruction manual appendix Figure 1 An oil pump 30 is fixedly installed on the oil tank 4. The oil inlet and outlet of the oil pump 30 are respectively fixedly connected to an oil inlet pipe 31 and an oil outlet pipe 32. The end of the oil inlet pipe 31 away from the oil pump 30 is fixedly connected to the lower inner side of the collection tank 3. The end of the oil outlet pipe 32 away from the oil pump 30 is fixedly connected to the upper inner side of the oil tank 4. A valve 33 is installed on the oil inlet pipe 31.

[0040] It should be noted that when the oil level meets the standard, valve 2 33 is opened and oil pump 30 is started to transfer the recovered oil collected in collection tank 3 to oil filling tank 4, so that it can be directly recycled for subsequent use.

[0041] Refer to the instruction manual appendix Figure 1 and Figure 2 The bottom of the base plate 1 is fixedly connected with multiple brakeable casters 34, and the upper end of the base plate 1 is fixedly connected with a handle 35.

[0042] It should be noted that the bottom of the base plate 1 has a brakeable caster 34 that works in conjunction with the handle 35 to facilitate the movement of the device and allow it to be flexibly adjusted to the designated guide rail. Once locked, it ensures stability.

[0043] Working principle:

[0044] 1. Waste oil collection and preliminary filtration: Based on the width of the production line guide rail, the extended groove 8 is adjusted by moving the sliding block 22 along the fixed rod 21 so that the oil collection trough 7 covers the bottom of the guide rail; at the same time, the cylinder 24 drives the support plate 25 to raise and lower the connecting cylinder 6, adjusting the oil collection trough 7 to the optimal collection height of 10-15cm from the guide rail. After the waste oil dripping from the guide rail falls into the oil collection trough 7, it is first pre-filtered by the filter screen 18 supported by the fixed ring 17 to intercept large-volume impurities, such as seal fragments. The filtered waste oil enters the oil guide pipe 9 through the connecting cylinder 6 and is finally introduced into the sedimentation tank 2.

[0045] II. Sedimentation and Iron Removal: The waste oil is placed in the sedimentation tank 2 and the electromagnetic adsorption plate 5 is activated to adsorb the iron impurities generated by the wear of the guide rail in the oil. At the same time, the fine particulate impurities in the oil settle naturally under the action of gravity, avoiding them from entering the subsequent stages with the oil. During the sedimentation process, the liquid level sensor 16 monitors the oil level in real time. When the oil level reaches the height, the vacuum generator 13 is triggered to start.

[0046] III. Filtration and Negative Pressure Transport: After the vacuum generator 13 is started, a negative pressure is formed between the sedimentation tank 2 and the filter 12. The clean oil in the sedimentation tank 2, which is two-thirds full, enters the filter 12 through the connecting pipe 10. The filter 12 intercepts tiny particulate impurities through its precisely designed porous structure. The filtered oil is then transported to the collection tank 3 for temporary storage through the first transport pipe 14, the vacuum generator 13, and the second transport pipe 15. When the oil level in the sedimentation tank 2 drops below two-thirds full, the liquid level sensor 16 triggers the vacuum generator 13 to shut down.

[0047] IV. Oil Refilling and Recycling: When the oil storage level in the collection tank 3 reaches the standard, open valve 33 on the oil inlet pipe 31, start the oil pump 30 on the oil filling tank 4, extract the clean oil from the collection tank 3 through the oil inlet pipe 31, and then transport it to the oil filling tank 4 through the oil outlet pipe 32 to complete the closed loop of oil recycling. The oil in the oil filling tank 4 can be directly reused for lubrication of the production line guide rails.

[0048] V. Maintenance and Adjustment: During regular maintenance, open the sealing cap 27 of the connecting pipe 26 on the sedimentation tank 2, open the valve 29 on the drain pipe 28 to discharge impurities and residual oil, and then turn off the power supply of the electromagnetic adsorption plate 5. The adsorbed iron filings will naturally loosen. Insert the adsorption tube of the external adsorption device through the connecting pipe 26 and use the adsorption tube to suck out the iron filings inside. If the filter screen 18 needs to be replaced, it can be taken out through the handle 19 for cleaning or replacement. If the device position needs to be adjusted, push the handle 35 on the base plate 1 and move the device through the brakeable caster 34 at the bottom. After reaching the target position, lock the caster to ensure stability.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
