Description

Technical Field

[0001] This utility model relates to the technical field of equipment for producing waste materials, and more specifically, to equipment for producing waste materials for the resource utilization of waste mineral oil. Background Technology

[0002] The development of waste material production equipment stems from the dual drive of global resource recycling needs and environmental protection policies. With the acceleration of industrialization, China generates a large amount of waste mineral oil every year due to product processing and equipment maintenance. If this waste oil is not properly treated, it will cause pollution of soil and groundwater. Moreover, most of the components in waste mineral oil still have recycling value. Traditional waste oil treatment methods, such as sulfuric acid and bleaching clay methods, have been phased out due to their serious environmental pollution.

[0003] A search revealed that CN118881603A discloses a centrifugal pump device with anti-clogging function, including a waste oil pump chamber, a filter anti-clogging component, and a mixing component. An oil outlet is opened at the bottom of the waste oil pump chamber. The filter anti-clogging component is connected to the right side of the waste oil pump chamber and includes a filter pump body, an anti-clogging filter screen, and a cleaning component, which can filter and clean the waste oil in the waste oil pump chamber. The mixing component is connected to the right side of the filter pump body and includes a mounting box, a stirring device, a centrifugal pump, and a return pipe. The mixing component can stir the waste oil and new oil. One end of the centrifugal pump is connected to the mixing component, and the other end is connected to the waste oil pump chamber. It can sweep and brush the mesh of the anti-clogging filter screen to prevent clogging due to the accumulation of impurities. This device ensures the filtration effect and speed of waste oil, allowing new oil and waste oil to be fully mixed and flowed back to the waste oil pump chamber through the return pipe, realizing the reuse of waste oil. The inventors discovered the following problems in the prior art during the development of this utility model:

[0004] Existing waste mineral oil production equipment uses only a single filter screen structure to simply filter out solid impurities when filtering waste mineral oil. However, waste mineral oil contains not only solid impurities but also a large amount of colloidal liquid impurities. These impurities cannot be removed by traditional filter screen structures. If these liquid impurities are not removed and directly enter the distillation unit, they will turn into gaseous state because their boiling point is the same as that of diesel or base oil. They will enter the oil storage tank along with diesel or base oil, resulting in a decrease in the purity of the mineral oil and thus a decrease in its overall value.

[0005] Therefore, a waste mineral oil resource utilization tailings production device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for the production of waste mineral oil tailings for resource utilization, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for the production of tailings from the resource utilization of waste mineral oil, comprising a filter assembly, a centrifugal mechanism, a distillation assembly, and a cooling assembly, characterized in that: a centrifugal mechanism is installed below the filter assembly, and a distillation assembly is installed on the side of the centrifugal mechanism; a cooling assembly is installed on the side of the distillation assembly away from the centrifugal mechanism; and an oil storage tank is provided at the liquid outlet end of the cooling assembly.

[0009] Preferably, the centrifugal mechanism includes a drive assembly, a connecting assembly, and an oil outlet assembly, with the connecting assembly mounted above the drive assembly and the oil outlet assembly mounted below the drive assembly, and the oil outlet assembly and the connecting assembly connected by a bearing.

[0010] Preferably, the drive assembly includes a first motor, a first rotating shaft, a sealing rubber ring, and a centrifuge tank. The first rotating shaft is mounted below the first motor, and the first motor and the first rotating shaft are connected by a coupling. A sealing rubber ring is placed on the outer diameter surface of the first rotating shaft, and the first rotating shaft and the sealing rubber ring are interference-fitted. The centrifuge tank is mounted below the first rotating shaft. The connecting assembly includes a connecting cylinder and a first oil inlet valve.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the existing technology, the waste mineral oil resource utilization tailings production device uses a centrifugal mechanism to centrifuge the waste mineral oil after solid impurities have been removed, so as to separate the mineral oil from the liquid colloidal impurities in the mineral oil and the tiny particles that were not completely removed in the filter screen assembly. This ensures that the impurities inside the mineral oil are extremely low when the mineral oil is distilled through the distillation assembly, and ensures the purity of the extracted different kinds of mineral oil.

[0017] 2. Compared with the existing technology, the waste mineral oil resource utilization tailings production device uses a cooling component to cool the mineral oil separated and purified by the distillation component, so that the mineral oil changes from the gaseous state during distillation back to the liquid state, and can flow smoothly from the bottom of the conveying pipe into the oil storage tank, thereby reducing the cooling time of the mineral oil and improving the overall waste mineral oil purification efficiency of the tailings production device.

[0025] 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.

[0026] Example 1

[0027] As attached Figures 1 to 4 The waste mineral oil resource utilization tailings production device shown includes a filter assembly 1, a centrifugal mechanism 2, a distillation assembly 3 and a cooling assembly 4. The centrifugal mechanism 2 is installed below the filter assembly 1, the distillation assembly 3 is installed on the side of the centrifugal mechanism 2, and the cooling assembly 4 is installed on the side of the distillation assembly 3 away from the centrifugal mechanism 2.

[0028] The process involves the following steps: When workers need to reprocess waste mineral oil, they first connect the filter assembly 1 and the centrifuge mechanism 2 of the waste material production device via a threaded connection. The waste mineral oil to be processed is then fed into the centrifuge mechanism 2 through the filter assembly 1. As the waste mineral oil passes through the filter assembly 1, fixed impurities are filtered onto the filter screen, while the waste mineral oil mixed with colloidal impurities enters the centrifuge mechanism 2. Once all the waste mineral oil to be processed has passed through the filter assembly and entered the centrifuge mechanism 2, the worker needs to detach the filter assembly 1 from the centrifuge mechanism 2 and close the opening and closing parts of the centrifuge mechanism 2, placing it in a closed state. At this point, the worker needs to turn on the switch of the centrifuge mechanism 2 to start it rotating and separate impurities from the waste mineral oil inside. The process separates colloidal impurities and small solid impurities that have not been filtered by the filter assembly from the waste mineral oil, causing them to settle below the centrifuge unit 2. After centrifugation, the worker needs to open the centrifuge unit 2 to allow the impurities deposited below it to flow out. Once the purified waste mineral oil flows out, the worker needs to close the centrifuge unit 2, then connect the distillation assembly 3 and the centrifuge unit 2 via a flange, and use a gear pump 20 to pump the waste mineral oil from the centrifuge unit 2 into the distillation assembly 3. In the distillation assembly 3, the mineral oils with different boiling points are heated at different temperatures, causing them to separate from the waste mineral oil in gaseous form. Then, in the cooling assembly 4, the oil is cooled by condensate water, returning it to a liquid state and flowing into the oil storage tank.

[0029] Example 2

[0030] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0031] In a preferred embodiment, the inner wall of the filter cartridge 5 is provided with an annular groove. The first layer filter screen 6, the second layer filter screen 7, and the third layer filter screen 8 are sequentially embedded in the groove. The first layer filter screen 6 has a mesh size of 200 mesh, the second layer filter screen 7 has a mesh size of 400 mesh, and the third layer filter screen 8 has a mesh size of 600 mesh. The first layer filter screen 6 is installed on the inner diameter surface of the filter cartridge 5. The first layer filter screen 6 and the filter cartridge 5 are connected by snap fasteners. The second layer filter screen 7 and the filter cartridge 5 are also connected by snap fasteners. The second layer filter screen 7 is placed below the first layer filter screen 6, and the third layer filter screen 8 is placed below the second layer filter screen 7. When waste mineral oil flows into filter cartridge 5, it first passes through the first filter screen 6, which filters out large particles such as mud and metal slag. The filtered mineral oil continues to flow downwards due to gravity and passes through the second filter screen 7, which filters out medium-sized impurity particles. The third filter screen 8 can filter out small impurity particles. The three-stage filtration design not only prevents fine filter screens from being clogged by large particles due to their small mesh size, but also effectively solves the problem that large mesh filter screens cannot filter small particles.

[0032] In a preferred embodiment, the centrifugal mechanism 2 includes a drive assembly 9, a connecting assembly 10, and an oil outlet assembly 11. The connecting assembly 10 is mounted above the drive assembly 9, and the oil outlet assembly 11 is mounted below the drive assembly 9. The oil outlet assembly 11 and the connecting assembly 10 are connected by a bearing.

[0033] In a preferred embodiment, the drive assembly 9 includes a first motor 12, a first rotating shaft 13, a sealing rubber ring 14, and a centrifuge tank 15. The first rotating shaft 13 is mounted below the first motor 12, and the first motor 12 and the first rotating shaft 13 are connected by a coupling. The sealing rubber ring 14 is placed on the outer diameter surface of the first rotating shaft 13, and the first rotating shaft 13 and the sealing rubber ring 14 are interference-fitted. The centrifuge tank 15 is mounted below the first rotating shaft 13. The connecting assembly 10 includes a connecting cylinder 16 and a first oil inlet valve 17. The first oil inlet valve 17 is mounted below the connecting cylinder 16, and the connecting cylinder 16 and the first oil inlet valve 17 are connected by a flange. When the worker needs to use the drive assembly 9 to drive the centrifuge mechanism 2 to rotate, the first motor 12 needs to be started. The first motor 12 will drive the centrifuge tank 15 to rotate through the first rotating shaft 13, so that the centrifuge tank 15 can separate the waste mineral oil inside. The sealing rubber ring 14 can prevent oil leakage at the connection between the centrifuge tank 15 and the first rotating shaft 13.

[0034] In a preferred embodiment, the oil outlet assembly 11 includes an oil outlet pipe 18, an oil outlet valve 19, and a gear pump 20. The oil outlet valve 19 is installed below the oil outlet pipe 18, and the gear pump 20 is placed on the side of the oil outlet valve 19. After the drive assembly 9 drives the centrifugal mechanism 2 to separate the waste mineral oil inside, the worker needs to open the oil outlet valve 19 to allow the waste liquid with residue after separation to be discharged from the separation mechanism through the oil outlet pipe 18. When mineral oil flows out of the oil outlet pipe 18, the worker needs to close the oil outlet valve 19 and connect the oil outlet valve 19 and the gear pump 20 with a pipe, and transfer the mineral oil to the distillation assembly 3 through the gear pump 20.

[0035] In a preferred embodiment, the distillation assembly 3 includes a second inlet valve 21, a distillation column 22, and a heating assembly 23. The distillation column 22 is mounted on the side of the second inlet valve 21, and the heating assembly 23 is placed below the distillation column 22. When the filtered and centrifuged mineral oil enters the distillation assembly 3 through the second inlet valve 21, the operator needs to control the temperature of the heating assembly 23 to heat the mineral oil to different degrees so that diesel oil and base oil with different boiling points can be separated from the mineral oil.

[0036] In a preferred embodiment, the heating assembly 23 includes a heating wire 24, a fuse 25, and a heating tube 26. The heating wire 24 is placed on the inner wall surface of the heating tube 26, and the fuse 25 is installed on the side of the heating wire 24. When the worker uses the heating assembly 23, the heating wire 24 will become hot due to the power supply, and the heating tube 26 can provide a place for the heating wire 24. The fuse 25 can be melted when the temperature of the heating wire 24 is too high, thereby protecting the heating assembly 23.

[0037] In a preferred embodiment, the cooling assembly 4 includes a water pump 27, a condenser pipe 28, and a delivery pipe 29. The condenser pipe 28 is mounted on the side of the water pump 27, and the water pump 27 and the condenser pipe 28 are connected by a flange. The liquid outlet end of the condenser pipe 28 is connected to the delivery pipe 29 by a check valve. When the mineral oil is heated, mineral oils with different boiling points will turn into gaseous state and enter the delivery pipe 29 after being heated to different degrees. The water pump 27 can provide condensate to the condenser pipe 28, so that the mineral oil in the delivery pipe 29 turns back into liquid state and enters the oil storage tank through the delivery pipe 29.

[0038] The working process of this utility model is as follows: First, when workers need to reprocess waste mineral oil, they need to connect the filter screen assembly 1 and the centrifugal mechanism 2 of the tailings production device with threads. Then, the waste mineral oil to be processed is put into the filter screen assembly 1. When the waste mineral oil flows into the filter cylinder 5 of the filter screen assembly 1, it will first pass through the first filter screen 6. The first filter screen 6 will filter out large particles such as mud and metal slag in the mineral oil. The filtered mineral oil will continue to flow downward due to gravity. When it passes through the second filter screen 7, medium-sized impurity particles in the mineral oil will be filtered out. The third filter screen 8 can filter out small impurity particles in the mineral oil. The filtered waste mineral oil will pass through the connecting cylinder 1 of the connecting assembly 10. 6. The waste mineral oil mixed with colloidal impurities flows into the drive assembly 9 of the centrifugal mechanism 2 through the first oil inlet valve 17. After all the waste mineral oil to be processed has passed through the filter assembly into the centrifugal mechanism 2, the worker needs to separate the filter assembly 1 from the centrifugal mechanism 2 and close the opening and closing parts of the centrifugal mechanism 2 to make it in a closed state. Then, the first motor 12 of the drive assembly 9 is started. The first motor 12 will drive the centrifugal barrel 15 to rotate through the first rotating shaft 13, so that the centrifugal barrel 15 can separate the waste mineral oil containing colloidal impurities and small solid impurities that have not been filtered by the filter assembly. The sealing rubber ring 14 can prevent oil leakage at the connection between the centrifugal barrel 15 and the first rotating shaft 13.

[0039] After centrifugation, the worker needs to open the oil outlet assembly 11 of the centrifuge unit 2, allowing the impurities deposited below the centrifuge tank 15 to flow out through the oil outlet pipe 18. Once the purified waste mineral oil flows out of the centrifuge unit 2, the worker needs to close the oil outlet valve 19, then connect the distillation assembly 3 and the centrifuge unit 2 via flanges, and open the second oil inlet valve 21. The waste mineral oil is then pumped from the centrifuge unit 2 into the distillation column 22 of the distillation assembly 3 via the gear pump 20. The mineral oil in the distillation assembly 3 is then heated by the heating assembly 23. During heating, the temperature sensor inside the distillation column 22 sends a value back to the temperature control module on the control panel. The operator can dynamically adjust the heating assembly 23 based on the feedback value. The heating power allows the heating element 23 to heat the mineral oil at different temperatures using the heating wire 24. This causes mineral oils with different boiling points to separate from the waste mineral oil in gaseous form and flow through the cooling element 4's conveying pipe 29 into the area where the condenser tube 28 is wound. During this process, the water pump 27 delivers condensate to the condenser tube 28, which cools the mineral oil in the conveying pipe 29, causing it to return to a liquid state and flow into the oil storage tank. When the temperature of the heating wire 24 becomes too high, the fuse 25 will melt, thus protecting the heating element 23. The heating tube 26 provides space for the placement of the heating wire 24. This is the working principle of the waste mineral oil resource utilization tailings production device.
