Description

Technical Field

[0001] This invention relates to the field of industrial oil production, specifically to an industrial oil production sedimentation device. Background Technology

[0002] In the production process of industrial oils, such as lubricating oil, hydraulic oil, insulating oil, and fuel oil, various impurities often become mixed in during the processing, storage, transportation, and use of the raw materials. To ensure the performance stability and safety of the oil, it is usually necessary to purify the oil through sedimentation and filtration processes. Specifically, the impurities in industrial oils mainly include the following categories: First, mechanical solid impurities, such as metal shavings (iron shavings, copper shavings, etc.) generated by equipment wear, welding slag residue, and rust particles; second, environmental pollutants, such as dust, silt, and fibrous impurities; and third, liquid or gaseous pollutants, such as moisture, gases, and some colloids or oxidation products. If these impurities are not removed in time, they will lead to a decline in oil performance and may even cause accelerated equipment wear or system failure.

[0003] In existing technologies, a combination of sedimentation and filtration is often used to purify industrial oil. The sedimentation process mainly relies on the density difference between the oil and impurities, allowing some larger particles to settle naturally through static or slow flow. However, this method has low separation efficiency and a long processing cycle, making it difficult to meet the needs of continuous production. Therefore, in actual industrial production, it is usually necessary to install a filtration device to trap solid particles in the oil through filter screens or filter elements to improve purification efficiency.

[0004] However, existing filtration devices still have significant shortcomings during long-term operation. Industrial oils contain a large number of fine particulate impurities, which continuously adhere to the filter screen surface or pores during filtration. As operating time increases, these impurities easily form a clogging layer on the filter screen, leading to gradually increasing filtration resistance, decreased flow rate, and even filtration failure. Furthermore, when the filter screen becomes clogged, it usually requires shutdown for disassembly, cleaning, or replacement of the filter media. Since filters are mostly closed structures, the cleaning process involves multiple steps such as draining oil, disassembly, rinsing, and reassembly, which is cumbersome and time-consuming. Moreover, under continuous industrial production conditions, the aforementioned shutdown and cleaning process directly interrupts the production flow, not only reducing equipment utilization but also affecting the overall production cycle and increasing labor maintenance costs.

[0005] Therefore, an industrial oil production sedimentation device is proposed to address the above problems. Summary of the Invention

[0012] Preferably, the upper end of the plug is frustum-shaped, and the outer ring of the upper end of the plug is provided with multiple stirring plates.

[0013] Preferably, a sealing tube extends downward from the center of the bottom of the material barrel, and the central shaft is rotatably connected inside the sealing tube.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Reference Figure 1 - Figure 10 ,as well as Figure 14 An industrial oil production sedimentation device includes a base 1, a material tank 2, and a rotating assembly, wherein the rotating assembly includes a drive assembly and a support assembly; a plurality of through holes 3 are arranged in a circumferential array on the base 1, and a filter screen 4 is provided in each through hole 3. The lower end of the through hole 3 is connected to a discharge pipe 5. A plurality of flushing holes 32 are opened on the outer ring of the base 1, and the flushing holes 32 penetrate into the through holes 3, and the inner end of the flushing hole 32 is located above the filter screen 4. A material bucket 2 is provided above the base 1. Multiple branch pipes 6 are symmetrically arranged at the lower end of the material bucket 2. Each branch pipe 6 has a rubber sealing ring at its lower end, and the lower end of the branch pipe 6 is slidably connected to the base 1 via the rubber sealing ring, ensuring a sliding seal between the branch pipe 6 and the base 1, as well as a sealed connection between the branch pipe 6 and the upper end of the through hole 3. Each branch pipe 6 has a sealing plate 12 at its lower end, which covers the through hole 3 that is not connected to the branch pipe 6. A drive assembly is provided between the material bucket 2 and the base 1. The drive assembly includes a motor 7 mounted on the base 1. A gear 8 is fixedly connected to the output end of the motor 7, and the gear 8 meshes with a gear ring 9. The gear ring 9 is coaxially fixed to the material bucket 2. A support assembly is provided between the material bucket 2 and the base 1. The support assembly includes a vertical rod 10 mounted on the base 1. A support ring 11 is fixedly connected to the upper end of the vertical rod 10, and the inner ring of the support ring 11 is rotatably connected to the outer ring of the material bucket 2. In this embodiment, the main purpose of the sedimentation device is to solve the problem of filter clogging. Specifically, the material tank 2 is used to hold industrial oil and to allow sedimentation, so that impurities in the industrial oil settle at the bottom of the material tank 2. The filter screen 4 mainly filters out impurities in the industrial oil. Furthermore, the industrial oil is injected into the material tank 2 by an oil pump, and the industrial oil is simultaneously undergoing sedimentation and being filtered through the filter screen 4. In this embodiment, four through holes 3 are provided on the base 1, and a filter screen 4 is installed in each through hole 3. Two branch pipes 6 are symmetrically arranged, and the branch pipes 6 are connected to two of the through holes 3. The filter screens 4 inside the two through holes 3 filter the industrial oil. The filtered industrial oil is discharged along the discharge pipe 5, while impurities remain on the filter screens 4. After a period of use, the filtration effect of the filter screens 4 inside the two through holes 3 deteriorates. The clogging status of the filter screens 4 can be directly judged by observing the discharge flow rate of the discharge pipe 5. If a flow valve is installed on the discharge pipe 5, the flow rate parameter per unit time can be observed. When the parameter approaches the preset minimum parameter, the filter screens 4 need to be filtered. Next, the operator controls the drive component in the background of the sedimentation device. Specifically, the drive motor 7 is activated. The gear 8 drives the gear ring 9 to rotate, which in turn drives the material tank 2 and the branch pipe 6 to rotate. The branch pipe 6 rotates to above the other two spare through holes 3, and then the above sedimentation and filtration process is repeated. As for the two exposed idle through holes 3, they are rinsed and cleaned. In this embodiment, the type of cleaning fluid is selected according to the type of industrial oil. For example, if the industrial oil is a lubricating oil, an alkaline cleaning fluid such as sodium hydroxide can be used; if the industrial oil is a metalworking oil, a neutral cleaning fluid can be used. The specific cleaning process is as follows: the cleaning fluid is injected into the discharge pipe 5 connected to the two idle through holes 3. A cleaning fluid delivery pipe is temporarily inserted into the bottom of the discharge pipe 5. An external pump injects the cleaning fluid into the discharge pipe 5, which then flows upwards along the through-hole 3 to backwash the filter screen 4, removing impurities. The cleanliness of the filter screen 4 can be judged by the hydraulic pressure in the delivery pipe. Initially, when cleaning the filter screen 4, due to severe sealing by impurities, the pressure parameter on the hydraulic gauge connected to the delivery pipe will be high. The initial parameter of this hydraulic gauge is the cleaning fluid supply pressure, controlled at 0.3-0.7 MPa, with a cleaning fluid flow rate controlled at 200-800 L / min. Specifically, for industrial oils with higher viscosity, the pressure is controlled at 0.5-0.7 MPa, and the flow rate at 600-800 L / min; for industrial oils with lower viscosity, the pressure is controlled at 0.3-0.7 MPa.5MPa, flow rate controlled between 200-500L / min. Select appropriate cleaning parameters based on the viscosity of the industrial oil to ensure thorough cleaning of impurities on filter screen 4 while minimizing cleaning fluid waste, achieving a balance between thorough cleaning and fluid conservation. When the hydraulic gauge pressure parameter falls below the minimum control range, the operator should stop the external pump, cease backwashing the filter screen 4, and remove the cleaning fluid delivery pipe. During the rinsing process, the filter screens 4 inside the other two through holes 3 perform industrial oil filtration. That is, the industrial oil filtration and the backwashing of the filter screens 4 are carried out simultaneously and do not interfere with each other. Compared with the traditional sedimentation filtration process, there is no need for cumbersome processes such as stopping the machine for disassembly, which ensures continuous industrial production, improves equipment utilization, and maintains a fast-paced production rhythm.

[0022] In this embodiment, a sealing plate 12 is provided at the port of branch pipe 6, such as... Figure 10 As shown, when the branch pipe 6 rotates to switch to the spare through hole 3 for filtration, the sealing plate 12 simultaneously covers the currently idle through hole 3, forming a physical isolation barrier to isolate the two adjacent through holes 3. During rinsing, cleaning fluid is injected into the idle discharge pipe 5, and the cleaning fluid rinses the filter screen 4 in the idle through hole 3. The upper end of the through hole 3 is covered and sealed by the sealing plate 12. The impurities that fall off during rinsing are discharged along the rinsing hole 32. The rinsing hole 32 is connected to the rinsing pipe 31, and the rinsing pipe 31 is equipped with a valve. During rinsing, the valve is opened to allow the cleaning fluid and impurities to be discharged. During filtration, the valve is closed to prevent industrial oil from leaking out of the rinsing hole 32. This design allows the material tank 2 to be rotated even when there is still industrial oil inside, because the sealing plate 12 will continuously cover the through hole 3 to prevent industrial oil from overflowing from the intersection point when the branch pipe 6 and the through hole 3 are about to be opposite each other. At this time, the material tank 2 can be rotated flexibly, and the branch pipe 6 and the through hole 3 can be switched at any time without considering whether there is residual oil in the material tank 2, further enhancing the adaptability and flexibility of the sedimentation device.

[0023] Reference Figure 7 - Figure 10 A circular hole is provided on each sealing plate 12 at a position away from the branch pipe 6. A circular shell 33 is provided at the upper end of the circular hole. A blade group 35 is provided inside the circular shell 33. A brush is provided at the lower edge of each blade. A brushing motor 34 is provided above the circular shell 33. The output end of the brushing motor 34 passes through the top plate of the circular shell 33 and is fixed to the center of the blade group 35. An electric telescopic rod is connected to the end shell of the brushing motor 34. The electric telescopic rod is mounted on the sealing plate 12. A touch switch 36 for controlling the operation of the electric telescopic rod is also provided on the sealing plate 12. In this embodiment, to achieve automated cleaning, a PLC control system is installed in the background of the sedimentation device. The PLC control system is used to control the operation of the entire sedimentation device. Multiple touch switches 36 are also installed on the base, one by one on the upper end of the through hole 3. A squeezing part 37 is installed on the sealing plate 12, located on one side of the circular shell 33. The squeezing part 37 is used to squeeze the contacts of the touch switches 36. Specifically, in the initial state, the PLC control system controls the electric telescopic rod to raise the brush motor 34 to the highest position, and the blade assembly 35 is placed inside the circular shell 33. When the filter screen 4 needs to be cleaned, the PLC control system controls the drive assembly, the sealing plate 12 rotates, and the circular shell 33 rotates to above the filter screen 4 that has just been filtered of industrial oil. The squeezing part 37 squeezes the contacts of the touch switches 36. The touch switches 36 and the PLC control system... The system operates in a coordinated manner. The PLC control system controls the electric telescopic rod to lower the brushing motor 34 and drives it to rotate. The rotating blade assembly 35 extends into the through hole 3, and the brushes on it clean the upper surface of the filter screen 4. Then, the external pump is driven to inject cleaning fluid into the discharge pipe 5 to rinse the filter screen 4 in the through hole 3. At this time, the brushes clean the more firmly attached impurities on the filter screen 4, improving the cleaning effect and efficiency. The blade assembly 35 can be set to an inclined position, which can create an upward suction effect on the cleaning fluid, while simultaneously pulling the impurities on the filter screen 4 upward and squeezing them to the flushing hole 32 position, so that the impurities detached from the filter screen 4 can be quickly discharged from the through hole 3. When the hydraulic pressure parameter on the conveying pipeline is lower than the minimum parameter of the control range, the PLC control system controls the external pump to stop the supply of cleaning fluid and stop the backwashing cleaning of the filter screen 4. In this embodiment, the setting of the trigger switch 36 enables the linkage between the rotation switching of the sealing plate 12 and the backwashing process. The rotation switching of the sealing plate 12 triggers the trigger switch 36, and the trigger switch 36 triggers the backwashing process. That is, the trigger switch 36 makes the rotation switching of the sealing plate 12 no longer a simple mechanical movement, but a pre-verification step of the backwashing process; the backwashing is no longer an independent external pump start-up action, but a necessary result of switching to the correct position. The two are upgraded from serial execution to conditional triggering. The motor rotation, sealing plate 12 rotation switching, triggering of the trigger switch 36, lowering of the electric telescopic rod, rotation of the brush motor 34, injection of cleaning fluid by the external pump, completion of rinsing, and return and reset of the electric telescopic rod can be realized by only the flow valve on the discharge pipe 5 and the PLC control system. This improves the overall reliability, efficiency and automation level of the sedimentation device.

[0024] Reference Figure 11 and Figure 12Each of the discharge pipes 5 has a lower port connected to a first pipe 13 and a second pipe 14. A valve plate 15 is provided inside the position where the first pipe 13 and the second pipe 14 are connected to the discharge pipe 5. The rotating shaft of the valve plate 15 extends to the outside of the discharge pipe 5, and the valve plate 15 is used to alternately block the first pipe 13 and the second pipe 14. Considering that some cleaning fluid will remain in the discharge pipe 5 after being injected, and may mix with the industrial oil, two branches are set on the discharge pipe 5, namely pipe 13 and pipe 2. In this embodiment, pipe 13 is used for conveying the cleaning fluid. A T-connector is set at the end of pipe 13 (at the conveying pipe interface) to connect to a compressed air purging pipeline. A solenoid valve is installed on the pipeline. Pipe 2 is used for conveying the filtered industrial oil. Specifically, during rinsing, the rotating shaft of valve plate 15 is rotated. The rotating shaft of valve plate 15 can be connected to an external servo motor. The servo motor is controlled by a PLC control system and drives the linkage component. When the material tank 2 rotates, it drives valve plate 15 to rotate. The second pipe 14 is blocked, and the first pipe 13 is connected to the discharge pipe 5. The cleaning fluid is injected into the first pipe 13 by an external pump. The cleaning fluid washes the filter screen 4 along the discharge pipe 5. After the washing is completed, the PLC control system shuts off the external pump. Then the PLC control system controls the solenoid valve to open and introduce 0.1-0.2MPa air. The air blows along the first pipe 13 and the discharge pipe 5, and finally discharges along the flushing pipe 31. After blowing for 1-3 minutes, it stops. Then the valve plate 15 is switched, the solenoid valve is closed, and the servo motor drives the valve plate 15 to deflect and block the first pipe 13. The discharge pipe 5 is connected to the second pipe 14. This design can make the cleaning fluid fully discharged, reduce the mixing of the cleaning fluid and industrial oil, and ensure the quality of industrial oil.

[0025] Reference Figure 1 - Figure 6 ,as well as Figure 13 The base 1 has a central shaft 16 at its center, the upper end of the central shaft 16 extends into the material bucket 2, and the outer ring of the upper end of the central shaft 16 is provided with a plug 17 to seal the bottom of the material bucket 2. The lower end of the central shaft 16 extends to the bottom of the base 1, and the surface of the base 1 is provided with a cylinder 18, the output end of the cylinder 18 is fixed to the lower end of the central shaft 16. The output end of cylinder 18 is connected to the central shaft 16, which can drive the central shaft 16 to move axially up and down, thereby driving the plug 17 to move up and down. This serves two main purposes: firstly, to control the flow rate of industrial oil in branch pipe 6; and secondly, to block branch pipe 6, suspending the filtration of industrial oil. Specifically, to control the flow rate, the output end of cylinder 18 drives the central shaft 16 to move up or down, causing the plug 17 to move up and down. This adjusts the gap between the plug 17 and the bottom surface of the material container 2, thereby adjusting the flow rate of industrial oil in branch pipe 6, and according to the industrial oil... The viscosity of the oil is controlled to regulate the flow rate, ensuring that the filtration rate is similar to the flow rate of industrial oil added to material tank 2. This allows the sedimentation device to operate continuously and stably, preventing the added industrial oil from overflowing from the top port of material tank 2 when the filtration rate is less than the replenishment rate. Alternatively, an electronic level gauge can be installed in material tank 2, connected to a PLC control system, to control the oil pump for replenishing industrial oil. When the liquid level in material tank 2 reaches a critical value, the PLC control system will stop the oil pump for replenishing industrial oil, thus preventing the added industrial oil from overflowing from the top port of material tank 2.

[0026] After the branch pipe 6 is blocked and the filter screen 4 is blocked, even if the backwash fluid is difficult to reach the initial filtration volume, the filter screen 4 can be replaced. At this time, control the cylinder 18, and the plug 17 moves down to completely block the lower port of the material tank 2, disconnecting the flow of industrial oil. Remove the filter screen 4 from the lower end of the through hole 3 and replace it with a new filter screen 4. Or, if there is oil leakage in the discharge pipe 5, the lower port of the material tank 2 can be blocked by the plug 17.

[0027] Reference Figure 1 - Figure 6 ,as well as Figure 13 The rotating assembly is also provided with multiple L-shaped support rods 19. The horizontal ends of the support rods 19 are all fixed to a sleeve 20. The upper end of the sleeve 20 is connected to an oil injection pipe 21. The lower end of the sleeve 20 extends into the material barrel 2, and multiple rectangular openings 22 are opened on the outer ring of the lower end of the sleeve 20. The outer ring of the upper end of the central shaft 16 is provided with a retaining strip 23, and the retaining strip 23 and the central shaft 16 are axially slidably connected in the sleeve 20. The sleeve 20 is positioned above the material bucket 2 and is supported on the support ring 11 via the support rod 19. The upper end of the central shaft 16 is axially slidably connected inside the sleeve 20. At this time, the lower end of the central shaft 16 is connected to the base 1, and the upper end is connected to the support rod 19, which improves the stability of the central shaft 16 and the relative rotational stability between the central shaft 16 and the material bucket 2. This ensures that the axes of the central shaft 16, the plug 17, and the material bucket 2 are approximately aligned, and the plug 17 can stably seal the lower port of the material bucket 2. Meanwhile, an oil injection pipe 21 is installed at the upper end of the sleeve 20. The replenished industrial oil flows into the material tank 2 along the rectangular opening 22 on the sleeve 20, which can stably and continuously replenish the industrial oil in the material tank 2.

[0028] Reference Figure 5 , Figure 6 and Figure 13 The upper end of the plug 17 is truncated cone-shaped, and a plurality of stirring plates 24 are provided on the outer ring of the upper end of the plug 17; A stirring plate 24 is provided for cleaning the material tank 2 itself. Specifically, when a thick layer of impurities accumulates on the inner wall of the material tank 2, the material tank 2 itself needs to be cleaned to prevent the thick layer of impurities from falling off and mixing into the industrial oil, affecting the permeability of the filter screen 4. For this purpose, a stirring plate 24 is provided on the plug 17. First, the driving central shaft 16 moves the plug 17 down, so that the plug 17 is close to the bottom port of the material tank 2, but it is not completely sealed, leaving a gap. Then, cleaning fluid is injected into the material tank 2 through the oil injection pipe 21. At the same time, the driving component drives the material tank 2 to rotate. During the rotation of the material tank 2, the central shaft 16 and the material tank 2 are in a state of relative rotation. At this time, the stirring plate 24 agitates the cleaning fluid. The cleaning fluid is agitated and cleans the impurities on the inner wall of the material tank 2. During the cleaning process, the impurities that fall off settle and are discharged along the gaps, realizing the agitation and cleaning of the material tank 2.

[0029] Reference Figure 6 - Figure 10 The material barrel 2 has a sealing tube 25 extending downward from the center of its bottom, and the central shaft 16 is rotatably connected to the sealing tube 25. The sealing tube 25 connects to the inside of the material barrel 2, and the central shaft 16 is rotatably connected inside the sealing tube 25. This serves two purposes: first, it improves the coaxiality between the central shaft 16 and the material barrel 2, avoiding uneven wear of the plug 17 caused by eccentric rotation and extending the service life of the bottom sealing pair; second, it delays the effective overlap length between the central shaft 16 and the material barrel 2, that is, it extends the path of industrial oil to permeate outward along the central shaft 16, improves the sealing performance at the rotatable connection between the central shaft 16 and the material barrel 2, and reduces the possibility of industrial oil leakage.

[0030] Reference Figure 9 , Figure 12 and Figure 13 Each of the through holes 3 is provided with a mounting box 26 for mounting the filter screen 4. The mounting box 26 is arranged vertically and vertically, and the mounting box 26 is provided with a ring body 27 for mounting the filter screen 4. The upper half of the mounting box 26 is provided with a chip discharge hole 28 that connects to the flushing hole 32. The mounting box 26 is designed for assembling the filter screen 4, allowing the filter screen 4 to be modularly assembled on the base 1, facilitating the replacement of the filter screen 4. Specifically, as shown... Figure 14 and Figure 15As shown, the mounting box 26 is generally in the shape of a flat cylindrical tube. Inside the mounting box 26, there is a ring 27 for mounting the filter screen 4. The filter screen 4 is pre-assembled in the mounting box 26. When the filter screen 4 needs to be replaced, the mounting box 26 and the filter screen 4 can be replaced directly. Because the operating space is limited and the viewing angle is affected when replacing the filter screen 4 in the through hole 3, it is relatively difficult to remove the filter screen 4 in the mounting box 26. However, replacing the mounting box 26 can avoid the above problems.

[0031] Reference Figure 12 and Figure 13 A limiting groove is provided on the inner side wall of each through hole 3, and a limiting block 29 adapted to the limiting groove is provided on the outer side wall of the mounting box 26. The limiting block 29 is fixed in the limiting groove by bolts. A limiting block 29 is provided on the mounting box 26. The mounting box 26 is assembled in the through hole 3, and the limiting block 29 is embedded in the limiting groove. The limiting block 29 is fixed in the limiting groove by bolts, thereby stabilizing the mounting box 26 in the through hole 3. At the same time, the limiting block 29 also serves to align the chip discharge hole 28 with the flushing hole 32, ensuring that the subsequent cleaning fluid and impurities can be discharged smoothly. At the same time, the chip discharge hole 28 can be set into a ring shape to increase the overlapping surface of the chip discharge hole 28 and the flushing hole 32. There is no need to consider the angle of the mounting box 26 in the through hole 3, making the installation more convenient.
