Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to an environmentally friendly lubricating oil production and processing purification equipment. Background Technology

[0002] Lubricating oil, composed of base oil and various functional additives, is an essential industrial consumable widely used in automobiles, machinery, and shipbuilding. Its core function is to form an oil film on the surfaces of friction pairs in equipment, reducing direct metal-to-metal friction and lowering the wear rate. It also provides cooling, rust prevention, and sealing functions, directly impacting the operating efficiency and service life of mechanical equipment. During the production and processing of lubricating oil, base oil, as the main component, undergoes multiple processes such as crude oil refining, distillation, and purification. Even so, base oil may still contain residual solid impurities (such as metal shavings and dust particles), colloids, asphaltenes, and other harmful substances. Simultaneously, additives may also introduce external impurities during storage, transportation, and addition. Direct use of lubricating oil containing impurities will not only disrupt the stability of the oil film, leading to increased wear on friction pairs, but may also clog equipment oil passages, scratch precision components, and even cause equipment malfunctions and downtime. Therefore, purification processes are essential to remove impurities from lubricating oil, ensuring its purity and performance to meet the high-quality lubrication requirements of modern machinery.

[0003] Based on the above, the inventors have discovered the following problems: Current lubricating oil purification largely relies on single-cylinder filtration equipment. This type of equipment is usually equipped with only one purification cylinder and one set of filtration components. Purification is achieved by intercepting impurities through the filter screen. In actual production, after long-term use, the filter screen will experience a decrease in filtration efficiency due to the accumulation of impurities. It needs to be disassembled, cleaned, or replaced regularly to restore filtration performance. However, when maintaining the filter screen in existing single-cylinder equipment, the raw material conveying must be stopped first, and the entire purification operation must be terminated. The equipment can only be restarted after the filter screen maintenance is completed, resulting in production interruption and reduced production efficiency.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an environmentally friendly purification equipment for lubricating oil production and processing, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly purification equipment for the production and processing of lubricating oil, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An environmentally friendly lubricating oil production and processing purification equipment includes an installation component, a switching component, and a purification component. The switching component includes a main pipe with a pair of through holes on one side of its outer wall. Each of the through holes has a branch pipe installed in it. A first solenoid valve and a second solenoid valve are respectively installed at the ends of the branch pipes away from the main pipe. The purification component includes a pair of purification cylinders with feed pipes connected to their outer walls near the upper end. The ends of the two feed pipes away from the purification cylinders are fixedly connected to the ends of the first solenoid valve and the second solenoid valve away from the branch pipes, respectively.

[0008] Furthermore, both purification cylinders are provided with an insertion seat inside, the insertion seat has an installation groove inside, a flow guide seat is installed inside the installation groove, and a stainless steel filter screen is installed inside the installation groove above the flow guide seat.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the mounting groove of the seat provides a stable installation space for the guide seat and the stainless steel filter screen. The guide seat can guide the lubricating oil passing through the stainless steel filter screen to flow out from the perforations. The stainless steel filter screen has excellent filtration accuracy and oil resistance, and can effectively intercept solid impurities in the lubricating oil (such as metal shavings, dust, and base oil refining residues). In addition, the stainless steel material can be repeatedly cleaned and recycled.

[0010] Furthermore, a connecting plate is installed on the bottom surface of the insertion seat, and a through hole is opened in the center of the insertion seat, the flow guide seat, and the connecting plate. A flow guide tube is connected to the bottom surface of the connecting plate, and a third solenoid valve is installed at the end of the flow guide tube away from the connecting plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the central perforation of the insert, the guide seat and the connecting plate forms a continuous guide channel. The pure lubricating oil filtered by the stainless steel filter screen can flow into the guide pipe through the perforation to ensure that there is no residue in the purified oil. The opening and closing of the third solenoid valve can realize the opening and closing of the guide pipe. When the lubricating oil in the purification cylinder is filtered, the pure oil can be discharged to the subsequent process by opening the third solenoid valve. When closed, it can prevent unfiltered lubricating oil or impurities from flowing out in advance.

[0012] Furthermore, the purification cylinder has a connecting ring fitted on its outer wall near the bottom. The connecting ring has four first screw holes along its circumference, and the connecting plate has four second screw holes along its circumference. Bolts are threaded between the opposing first and second screw holes, and a sealing ring is provided between the connecting ring and the connecting plate.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the connecting ring and the connecting plate are connected by bolt threads, which can stably fix the insert in the purification cylinder, prevent the insert from shifting due to lubricating oil impact or cylinder pressure during the purification process, and ensure the stability of the filtration and flow guiding structure; the sealing ring between the connecting ring and the connecting plate can fill the connection gap, preventing lubricating oil from leaking from the gap, and the bolt connection is easy to disassemble. When it is necessary to maintain the stainless steel filter screen, the insert can be removed simply by removing the bolts.

[0014] Furthermore, a piston is provided above the stainless steel filter screen in the purification cylinder, and a cylinder is installed on the top surface of the purification cylinder. The telescopic end of the cylinder passes through the purification cylinder and is fixedly connected to the top surface of the piston.

[0015] The beneficial effects of adopting the above-mentioned further solution are that after the cylinder is started, its telescopic end pushes the piston to move downward in the purification cylinder, applying uniform pressure to the lubricating oil above the stainless steel filter screen, forcing the lubricating oil to pass through the stainless steel filter screen quickly. Compared with natural filtration or gravity filtration, the pressure effect can significantly shorten the filtration time and improve the purification efficiency. At the same time, the downward movement of the piston can also squeeze the residual lubricating oil in the cylinder, reduce the retention and waste of oil in the cylinder, improve the utilization rate of raw materials, and conform to the concept of environmentally friendly production.

[0016] Furthermore, the feed pipe is located on one side below the region where the piston is initially positioned.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, in the initial state, the piston is located at the top of the purification cylinder, and the feed pipe is located below it, which can ensure that after the lubricating oil raw material enters the purification cylinder through the feed pipe, it flows directly to the area above the stainless steel filter screen and will not be blocked by the piston.

[0018] Furthermore, the mounting assembly includes a mounting strip, on one side of the outer wall of the mounting strip a pair of connecting strips, one side of the outer wall of the pair of connecting strips being fixedly connected to the outer walls of the two purification cylinders respectively, and a threaded hole is provided at the center of the mounting strip.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the connecting strip fixes the two purification cylinders to the mounting strip to form an integral structure, which enhances the overall stability of the equipment and avoids the problem of easy tipping over when a single purification cylinder is placed independently; the threaded hole in the center of the mounting strip can be used to fix the equipment to the support on the production site with bolts.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: the main pipeline of this environmentally friendly lubricating oil production and processing purification equipment serves as the main transportation channel for lubricating oil raw materials. It is connected to two purification cylinders through a pair of branch pipelines. The first solenoid valve and the second solenoid valve can independently control the opening and closing of the corresponding branch pipelines. When one of the purification cylinders is undergoing maintenance, the feed of that cylinder can be closed by the first solenoid valve, while the feed of the other purification cylinder can be opened by the second solenoid valve, thus avoiding production interruptions caused by cleaning and maintenance of traditional single-cylinder equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: an environmentally friendly lubricating oil production and processing purification equipment, including an installation component 1, a switching component 2, and a purification component 3. The switching component 2 includes a main pipe 21, with a pair of through holes on one side of the outer wall of the main pipe. Each of the through holes has a branch pipe 22 installed inside. At the end of the branch pipe 22 away from the main pipe 21, a first solenoid valve 23 and a second solenoid valve 24 are respectively installed. The purification component 3 includes a pair of purification cylinders 31, with feed pipes connected to the outer walls of the pair of purification cylinders 31 near the upper end. The ends of the two feed pipes away from the purification cylinders 31 are respectively fixedly connected to the ends of the first solenoid valve 23 and the second solenoid valve 24 away from the branch pipes 22. Each of the two purification cylinders 31 has an insertion seat 34 inside, with an installation groove 35 inside the insertion seat 34. A guide seat is installed inside the installation groove 35. 36. A stainless steel filter screen 37 is installed inside the mounting slot 35 above the guide seat 36. A connecting plate 39 is installed on the bottom surface of the insertion seat 34. A through hole is opened at the center of the insertion seat 34, the guide seat 36, and the connecting plate 39. A guide pipe 310 is connected to the bottom surface of the connecting plate 39. A third solenoid valve is installed at the end of the guide pipe 310 away from the connecting plate 39. The lubricating oil raw material is first transported to the main pipeline 21. The main pipeline 21 serves as the main transport channel. The raw material is guided to two purification cylinders 31 through a pair of branch pipelines 22. When one of the purification cylinders 31 needs to be used for purification, the solenoid valve on the corresponding branch pipeline 22 is opened. For example, if the left purification cylinder 31 is used, the first solenoid valve 23 is opened. If the right is used, the second solenoid valve 24 is opened. The raw material enters the purification cylinder 31 through the branch pipeline 22, the solenoid valve, and the feed pipe. The lubricating oil entering the purification cylinder 31 flows to the stainless steel filter screen 37 in the mounting groove 35 of the insertion seat 34. The stainless steel filter screen 37, with its excellent filtration accuracy and oil resistance, intercepts solid impurities such as metal scraps, dust, and residual impurities from base oil refining in the raw materials. At the same time, the guide seat 36 guides the filtered pure lubricating oil through the connecting hole in the center of the insertion seat 34, the guide seat 36, and the connecting plate 39, and flows into the guide pipe 310 below. After the lubricating oil in the purification cylinder 31 has been filtered, the third solenoid valve on the guide pipe 310 is opened, and the pure lubricating oil can be discharged through the guide pipe 310 to the subsequent production process. If it is necessary to close the guide pipe 310 or prevent unfiltered oil from flowing out prematurely, the third solenoid valve can be closed. When one of the purification cylinders 31 needs to be cleaned or maintained by the stainless steel filter screen 37, the corresponding solenoid valve is closed. For example, if the left purification cylinder 31 is being maintained, the first solenoid valve 23 is closed. At the same time, the solenoid valve of the other purification cylinder 31, such as the second solenoid valve 24, is opened, allowing the raw material to enter the other purification cylinder 31 for further purification. This avoids production interruptions caused by maintenance in traditional single-cylinder equipment and ensures continuous operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution: A connecting ring 38 is fitted on the outer wall of the purification cylinder 31 near the bottom. Four first screw holes are provided circumferentially on the connecting ring 38, and four second screw holes are provided circumferentially on the connecting plate 39. Bolts are threadedly connected between the opposing first and second screw holes. A sealing ring is provided between the connecting ring 38 and the connecting plate 39. A piston 32 is positioned above the stainless steel filter screen 37 in the purification cylinder 31. A cylinder 33 is mounted on the top surface of the purification cylinder 31. The telescopic end of the cylinder 33 passes through the purification cylinder 31 and is fixedly connected to the top surface of the piston 32. The feed pipe is located below the area where the piston 32 is initially positioned. The mounting assembly 1 includes a mounting strip 11. A pair of connecting strips 12 are mounted on one side of the outer wall of the mounting strip 11. One side of the outer wall of the pair of connecting strips 12 is fixedly connected to the outer walls of the two purification cylinders 31 respectively. A threaded hole is provided at the center of the mounting strip 11. Using the threaded hole in the center of the mounting strip 11, the equipment is fixed to the support on the production site with bolts. During the purification operation, the piston 32 is initially located at the top of the purification cylinder 31. Since the feed pipe is located below the initial position of the piston 32, the raw material can flow directly to the top of the stainless steel filter screen 37 after entering the purification cylinder 31 through the feed pipe, without being blocked by the piston 32. The cylinder 33 is activated, and its telescopic end pushes the piston 32 downward in the purification cylinder 31, applying uniform pressure to the lubricating oil above the stainless steel filter screen 37, forcing the lubricating oil to pass through the stainless steel filter screen 37 quickly, greatly shortening the filtration time and improving the purification efficiency. At the same time, the downward pressure of the piston 32 can also squeeze the residual lubricating oil in the cylinder, reducing oil retention and waste. After filtration, the third solenoid valve is opened as needed to discharge the pure oil. If the stainless steel filter screen 37 needs to be maintained, the bolts between the connecting ring 38 and the connecting plate 39 can be removed and placed into the seat 34.

[0031] Specifically, the working principle of this environmentally friendly lubricating oil production and processing purification equipment is as follows: When in use, the equipment is first fixed to the support of the production site by bolts through the threaded hole in the center of the mounting strip 11; the lubricating oil raw material to be purified is first transported to the main pipeline 21, which serves as the main transport channel, and the raw material is guided to the two purification cylinders 31 through the branch pipelines 22 on both sides. The operator selects the purification cylinder 31 to be used according to production needs. If one purification cylinder 31 is used, the solenoid valve on the corresponding branch pipe 22 is opened. For example, if the left purification cylinder 31 is used, the first solenoid valve 23 is opened, and if the right one is used, the second solenoid valve 24 is opened. The raw material enters the purification cylinder 31 through the branch pipe 22, the first solenoid valve 23 or the second solenoid valve 24, and the feed pipe. Since the feed pipe is located below the initial position of the piston 32, and the piston 32 is initially located at the top of the purification cylinder 31, the raw material can flow directly to the stainless steel filter screen 37 inside the seat 34 of the purification cylinder 31 without being blocked by the piston 32. Then, the cylinder 33 on the top surface of the purification cylinder 31 is activated. The extension end of the cylinder 33 pushes the piston 32 downward in the purification cylinder 31, applying uniform pressure to the lubricating oil above the stainless steel filter screen 37. Under the pressure, the lubricating oil quickly passes through the stainless steel filter screen 37, which has high filtration accuracy and oil resistance. The stainless steel filter screen 37 effectively blocks... The filter removes solid impurities such as metal scraps, dust, and residual impurities from base oil refining from the raw materials. Simultaneously, the guide seat 36 within the insertion seat 34 guides the filtered pure lubricating oil through the connecting hole at the center of the insertion seat 34, guide seat 36, and connecting plate 39, allowing it to flow smoothly into the guide pipe 310 on the bottom surface of the connecting plate 39. After the lubricating oil in the purification cylinder 31 is filtered, the third solenoid valve on the guide pipe 310 is opened, and the pure lubricating oil is discharged through the guide pipe 310 to subsequent production processes. When the stainless steel filter screen 37 of one of the purification cylinders 31 needs cleaning or maintenance, the first solenoid valve 23 of the corresponding branch pipe 22 is closed, and the second solenoid valve 24 of the other purification cylinder 31 is opened, allowing the raw materials to enter the other purification cylinder 31 for continued purification, avoiding production interruption. If the stainless steel filter screen 37 needs to be disassembled for maintenance, simply unscrew the bolts between the connecting ring 38 at the bottom of the purification cylinder 31 and the connecting plate 39 to remove the insertion seat 34 for maintenance of the stainless steel filter screen 37.

[0032] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
