Description

Technical Field

[0001] The invention relates to the technical field of cone crusher crushing, in particular to a lubrication filtering system for a cone crusher and a lubrication oil filtering method thereof. Background Art

[0002] Cone crusher is a device that uses a conical crushing chamber to crush materials. The crushing of materials is achieved through the relative movement between the fixed cone and the mobile cone. The crushing chamber of the cone crusher is conical in shape and consists of a fixed cone and a mobile cone. The mobile cone can swing along the axis of the fixed cone. The ore or rock to be crushed enters the crushing chamber from the feed port and is gradually crushed and crushed by the extrusion force between the mobile cone and the fixed cone. The crushed material is discharged through the discharge port at the bottom of the crushing chamber to complete the crushing process. The lubrication system of the cone crusher usually includes components such as an oil tank, an oil pump, a filter, a cooler, and a temperature controller. The lubricating oil is drawn from the oil tank, pressurized by the oil pump, and then enters the cooler through the filter for cooling. Then the oil temperature is adjusted by the temperature controller, and finally enters the machine through various lubrication points for lubrication. The inventor found that the lubricating oil used in the existing cone crusher has a short service life and often needs to be replaced. During the process of replacing the lubricating oil, the cone crusher cannot be used. At the same time, the inventors found that the recovered lubricating oil can actually still be used, that is, the existing cone crusher does not fully utilize the lubricating oil, resulting in waste.

[0016] Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention.

The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale.

DETAILED DESCRIPTION

[0018] Refer to the following Figures 1 to 6 The lubrication filtration system and lubrication oil filtration method for a cone crusher according to an embodiment of the present invention will be described.

[0019] Figure 1 : is a schematic structural diagram of a lubrication and filtration system for a cone crusher according to an embodiment of the present invention, Figure 1 As shown, and refer to Figures 2 to 6 The embodiment of the present invention provides a lubricating and filtering system for a cone crusher, which includes a lubricating oil quality acquisition device, two oil tanks containing lubricating oil, an oil supply pump group 10, a lubricating oil cleaning device 20 and a lubricating oil switching device. The lubricating oil quality acquisition device is configured to acquire the quality of the lubricating oil in the oil tank. The lubricating oil switching device is configured to clean part of the lubricating oil in the two oil tanks by the lubricating oil cleaning device 20 according to the quality in the oil tanks, and to supply the remaining lubricating oil in the two oil tanks to the lubricating point 12 on the cone crusher through the oil supply pump group 10.

[0020] In the embodiment of the present invention, the quality of the lubricating oil in the oil tank can be obtained in real time to determine whether the lubricating oil in the oil tank can continue to be used for lubrication. If it cannot be used for lubrication, a lubricating oil with better quality is switched for lubrication to protect the cone crusher and prevent the cone crusher from being damaged by the lubricating oil. The lubricating oil can be purified in time, which can increase the service life of the lubricating oil and reduce the frequency of changing the lubricating oil.

[0021] In some alternative embodiments of the present invention, three oil supply tanks are provided for oil supply, wherein one oil supply tank is used for oil supply, and one of the other two oil supply tanks is used for temporarily storing the lubricating oil to be cleaned, and the other is used for receiving the cleaned lubricating oil. When the oil supply tank needs to be cleaned, the oil tank that does not store the lubricating oil among the other two oil tanks is used to receive the cleaned lubricating oil, and the oil tank that stores the clean lubricating oil starts to supply oil for lubrication at this time. That is to say, the three oil tanks in this embodiment are used in a cycle, and there must be an empty oil tank. However, in the embodiment of the present invention, two oil tanks are used, and the lubricating oil switching device includes two partitions, each of which is movably arranged in an oil tank and configured to divide the oil tank into two spaces. Both oil tanks can be filled with lubricating oil, and it is obvious that the total volume of the oil tanks used is smaller. If two oil tanks are used in the embodiment of the present invention under the same total volume, it is obvious that more lubricating oil can be stored. Moreover, in the embodiment of the present invention, the lubricating oil is used to lubricate the lubrication point 12, and the lubricating oil is used to clean. Both can be performed simultaneously without affecting each other, so that even if the cleaning time is too long, it will not affect the normal crushing of the cone crusher, so that the crushing efficiency of the cone crusher is high, and the lubricating oil can also be cleaned efficiently and effectively, thereby increasing the service life of the lubricating oil.

[0022] In some embodiments of the present invention, Figure 1 As shown, both oil tanks are oil supply tanks 31. Each oil tank is provided with an oil return port, an oil outlet port, a first filter port, and a second filter port. Each partition 41 separates the oil supply tank 31 into two spaces, namely a first space 32 and a second space 33. By setting a partition 41, each oil supply tank 31 is divided into two spaces, so that when the lubricating oil in the oil supply tank 31 is cleaned, the lubricating oil after cleaning and the lubricating oil before cleaning are no longer mixed, thereby improving the cleaning efficiency. Each partition 41 is movably arranged in the oil supply tank 31 so that the oil return port and the oil outlet port of each oil tank are connected to the first space 32 at the same time, or are connected to the second space 33 at the same time. The first filter port is connected to the first space 32, and the second filter port is connected to the second space 33. When the oil return port of one oil tank is connected to the lubrication point 12 and the oil outlet is connected to the lubrication point 12 through the oil supply pump group 10, one of the first filter port and the second filter port of another oil tank is controllably connected to the inlet of the lubricating oil cleaning device 20, and the other is connected to the outlet of the lubricating oil cleaning device 20.

[0023] In the embodiment of the present invention, when the first space 32 of one oil supply tank 31 supplies oil to and returns oil to the lubrication point 12, the first space 32 of another oil supply tank 31 stores cleaned lubricating oil. When the lubricating oil in the first space 32 of one oil supply tank 31 needs to be cleaned, the cleaned lubricating oil stored in the first space 32 of another oil supply tank 31 is used to supply oil to and return oil to the lubrication point 12. The inlet of the lubricating oil cleaning device 20 is connected to the first space 32 of one oil supply tank 31, and the outlet is connected to the second space 33 of one oil supply tank 31. After cleaning, the second space 33 of one oil supply tank 31 stores clean lubricating oil. The next time the oil supply tank is used for oil supply, the second space is used for oil supply. Furthermore, in order to improve the cleaning efficiency, cleaning can also be performed repeatedly. For example, the inlet of the lubricating oil cleaning device 20 is connected to the first space 32 of an oil supply tank 31, and the outlet is connected to the second space 33 of an oil supply tank 31. After cleaning, the inlet of the lubricating oil cleaning device 20 is connected to the second space 33 of an oil supply tank 31, and the outlet is connected to the first space 31 of an oil supply tank 31, so as to achieve multiple cleanings.

[0024] In the embodiment of the present invention, the first space 32 and the second space 33 in the oil tank can be switched to the lubricating oil storage space after cleaning or the lubricating oil storage space before cleaning at will, so there is no need to set a special driving mechanism for the movement of the partition 41. That is, the movement of the partition is driven by the change of the amount of lubricating oil in the first space 32 and the second space 33, and there is no need to set a special driving mechanism for the movement of the partition, which has a simple structure, convenient control and low cost.

[0025] In some embodiments of the present invention, the lubricating oil switching device further includes two oil inlet pipelines 34 and two oil outlet pipelines 35. The inlets of the two oil inlet pipelines 34 are both connected to the lubrication point 12, and the outlets of the two oil inlet pipelines 34 are respectively connected to the two oil return ports; a first on-off valve 36 is provided on each oil inlet pipeline 34. The inlets of the two oil outlet pipelines 35 are respectively connected to the two oil outlets; the outlets of the two oil outlet pipelines 35 are connected to the oil supply pump group 10; and a second on-off valve 37 is provided on each oil outlet pipeline 35. By providing the first on-off valve 36 and the second on-off valve 37 instead of using a switching valve, the flow of the lubricating oil can be smoother and the control switching can be simpler.

[0026] In some embodiments of the present invention, the lubricating oil switching device further includes a first temporary storage box 21 and a second temporary storage box 22. The first temporary storage box 21 is arranged at the inlet of the lubricating oil cleaning device 20, and the first temporary storage box 21 is respectively connected to the two first filter ports and the two second filter ports through four first pipelines. A third on-off valve 23 is arranged on each first pipeline. The second temporary storage box 22 is arranged at the outlet of the lubricating oil cleaning device 20, and the second temporary storage box is respectively connected to the two first filter ports and the two second filter ports through four second pipelines. A fourth on-off valve 24 is arranged on each second pipeline.

[0027] By providing the first temporary storage box 21, the second temporary storage box 22, the third on-off valve 23 and the fourth on-off valve 24, the diameter of the pipeline between the lubricating oil cleaning device 20 and the oil tank is increased, the lubricating oil flows smoothly, and the switching between the first space 32 and the second space 33 is smoother.

[0028] In some embodiments of the present invention, a plurality of heat dissipation rods 38 are provided in each oil supply tank 31, and a plurality of guide holes are correspondingly provided on the partition 41, and each heat dissipation rod 38 passes through the guide hole. This arrangement does not require a guide mechanism to be provided on the inner wall of the oil supply tank 31, and the processing is relatively convenient. The edge of the partition is flat, and it is easy to seal. The arrangement of a plurality of heat dissipation rods 38 can make the movement of the partition 41 smooth and stable, and will not tilt, so that the independence effect between the first space 32 and the second space 33 is better. The arrangement of the heat dissipation rods 38 also facilitates the oil tank to dissipate the heat of the lubricating oil when providing the lubricating oil to the lubrication point 12.

[0029] Further, in some embodiments of the present invention, the heat dissipation rod 38 can be configured as a heat dissipation air duct or a heat dissipation liquid pipe according to the need of heat dissipation. In other words, the heat dissipation rod 38 is a heat dissipation air duct or a heat dissipation liquid pipe. The heat dissipation air duct can be connected to a fan. The heat dissipation liquid pipe is circulatedly connected to a liquid pump and a coolant tank. In order to further improve the strength of the heat dissipation air duct, ribs are provided in the heat dissipation air duct, which can not only improve the strength, but also perform heat exchange with the airflow passing through, thereby improving the heat dissipation effect of the heat dissipation air duct.

[0030] In some embodiments of the present invention, Figure 2 As shown, the two oil tanks are respectively the oil supply tank 31 and the cleaning oil tank 42. The lubricating oil switching device includes a valve device 43. The two partitions are respectively the first partition 44 and the second partition 45.

[0031] The first partition plate 44 is disposed in the oil supply tank 31, and the two spaces divided into the oil supply tank 31 are the third space and the fourth space. The oil supply tank 31 is provided with a first oil outlet and a first oil return port communicating with the third space, and a second oil outlet and a second oil return port communicating with the fourth space. The first oil return port and the second oil return port are communicated with the lubrication point 12, and the first oil outlet and the second oil outlet are communicated with the lubrication point 12 through the oil supply pump group 10. The first partition plate 44 is movably disposed in the oil supply tank 31.

[0032] The second partition plate 45 is movably disposed in the clean oil tank 42, and separates the clean oil tank 42 into two spaces, namely a fifth space 46 and a sixth space 47. The fifth space 46 is communicated with the inlet of the lubricating oil cleaning device 20, and the sixth space 47 is communicated with the outlet of the lubricating oil cleaning device 20.

[0033] The valve device 43 is configured to: connect the third space with the fifth space 46 and connect the fourth space with the sixth space 47; or connect the third space with the sixth space 47 and connect the fourth space with the fifth space 46 to switch the lubricating oil in the oil supply tank 31 with the lubricating oil in the clean oil tank 42.

[0034] In the embodiment of the present invention, when the third space is supplied with oil, when the lubricating oil in the third space needs to be cleaned, the third space is connected to the fifth space 46, and the fourth space is connected to the sixth space 47. The cleaned lubricating oil in the sixth space 47 will enter the oil supply pump group 10 and the lubrication point 12 through the fourth space. After passing through the fourth space, the lubricating oil will prompt the first partition 44 to move, squeeze the third space, and also facilitate the lubricating oil in the third space to enter the fifth space 46. After the lubricating oil in the third space completely enters the fifth space 46, the lubricating oil cleaning device 20 is started, so that the lubricating oil can be cleaned. At the same time, the cleaned lubricating oil entering the fourth space can be supplied to the lubrication point 12 through the second oil outlet and the second oil return port, so that the oil supply is switched to the fourth space.

[0035] Similarly, when the lubricating oil in the fourth space needs to be cleaned, the corresponding steps can be performed to clean it. In the embodiment of the present invention, while the lubricating oil is switched, the crushing of the cone crusher is not affected.

[0036] Moreover, in the embodiment of the present invention, the clean oil tank 42 is only used to provide oil to the lubrication system during actual operation and does not receive high-temperature oil. Since it does not need to withstand changes in high oil temperature, the design requirements for the clean oil tank 42 are relatively low, thereby reducing the cost of the oil tank, thereby reducing the cost of the lubrication and filtration system, and reducing the cost of the cone crusher.

[0037] In some embodiments of the present invention, a plurality of heat dissipation rods 38 are provided in the oil supply tank 31. The cleaning oil tank 42 only needs to be provided with guide rods, and no heat dissipation device is required, which can also reduce costs.

[0038] In some embodiments of the present invention, Figure 4 As shown, the oil supply tank 31 is mounted on the clean oil tank 42, the length of the clean oil tank 42 is greater than the length of the oil supply tank 31, and the internal cross-sectional area of ​​the clean oil tank 42 is smaller than the internal cross-sectional area of ​​the oil supply tank 31. The first partition 44 is mounted on the clean oil tank 42. The oil supply tank 31 is mounted on the clean oil tank 42 to improve the heat dissipation and cooling effect. The middle part of the oil supply tank 31 has clean oil with a lower temperature, which increases the heat dissipation area, so that the oil supply tank 31 has sufficient heat dissipation effect.

[0039] In some embodiments of the present invention, the valve device 43 is a four-way valve, which has a first communication port, a second communication port, a third communication port and a fourth communication port; the third space is connected to the first communication port, the fourth space is connected to the second communication port, the fifth space 46 is connected to the third communication port, and the sixth space 47 is connected to the fourth communication port. By setting a four-way valve, one valve can be controlled, the structure is simple, the control is convenient, the parts are few, and the failure is few, which is particularly suitable for large equipment such as cone crushers.

[0040] In some embodiments of the present invention, the lubricating oil switching device further includes an oil inlet main pipe, two oil inlet branch pipes 48, two oil outlet branch pipes 49 and an oil outlet main pipe. The inlet of the oil inlet main pipe is connected to the lubrication point 12, the inlets of the two oil inlet branch pipes 48 are connected to the outlet of the oil inlet main pipe, and the outlets of the two oil inlet branch pipes 48 are respectively connected to the first oil return port and the second oil return port. A fifth on-off valve is provided on each oil inlet branch pipe 48.

The ninth space 55 is connected to the outlet of the lubricating oil cleaning device 20; the tenth space 56 is connected to the lubrication point 12 through the oil supply pump group 10. Or the tenth space 56 is connected to the seventh space 53.

[0042] The third partition 51 and the fourth partition 52 are both telescopic plates. The third partition 51 is in an expanded state when it starts to move from the initial position to the terminal position, so that the seventh space 53 becomes larger and the eighth space 54 becomes smaller. The third partition 51 is in a contracted state when it moves from the terminal position to the initial position, so that the seventh space 53 and the eighth space 54 are connected, so that the lubricating oil that needs to be cleaned in the seventh space 53 enters the eighth space 54. The fourth partition 52 is in an expanded state when it starts to move from the initial position to the terminal position, so that the ninth space 55 becomes larger and the tenth space 56 becomes smaller. The fourth partition 52 is in a contracted state when it moves from the terminal position to the initial position, so that the ninth space 55 and the tenth space 56 are connected, so that the cleaned lubricating oil in the ninth space 55 enters the tenth space 56.

[0043] In the embodiment of the present invention, the third partition 51 and the fourth partition 52 are both connected to a driving device to drive the third partition 51 and the fourth partition 52 to move. By setting the third partition 51 and the fourth partition 52 as telescopic plates, when the lubricating oil in the seventh space 53 needs to be cleaned, the third partition 51 is moved to the initial position, and the seventh space 53 and the eighth space 54 are connected at this time, and the lubricating oil in the seventh space 53 enters the eighth space 54, realizing the switching of the space. The eighth space 54 is used for cleaning the lubricating oil. During the cleaning process of the lubricating oil, the third partition 51 moves from the initial position to the terminal position. Similarly, when the lubricating oil in the ninth space 55 needs to enter the lubrication point 12, the fourth partition 52 is moved to the initial position, and the ninth space 55 and the tenth space 56 are connected at this time, and the lubricating oil in the ninth space 55 enters the tenth space 56, realizing the switching of the space. The ninth space 55 is used to receive the cleaned lubricating oil.

When it is not necessary to move the baffle 62 to align or close the oil hole 63, the output rod closes the corresponding perforation and does not extend into the corresponding oil tank to prevent the movement of the partition from being affected. If it is necessary to move the baffle 62, the output rod moves up and down to enter the oil tank, and then rotates so that the threaded hole at the end of the output rod docks with the threaded column on the lifting rod 64, and then the output rod rises or falls, thereby driving the baffle 62 to move. After the baffle 62 moves to the corresponding position, the output rod is disengaged from the lifting rod 64 and resets by rotating and lifting. Because the baffle 62 needs to be moved at two positions in each oil tank, two rotating lifting devices are set.

[0045] In some preferred embodiments of the present invention, Figure 5 As shown, a first magnet 65 is provided at the upper end of the lifting rod 64. A second magnet and a third magnet are provided at corresponding positions on the outer side of the corresponding oil tank. The first magnet 65 and the second magnet are configured to move in an attracting manner, and the first magnet 65 and the third magnet are configured to move in a repelling manner. By providing the second magnet and the third magnet, the movement direction of the first magnet 65 is opposite, thereby realizing the opening or closing of the oil hole 63 and realizing the change of the function of the baffle 62. In some alternative embodiments of the present invention, the second magnet and the third magnet are both electromagnets.

[0046] In some embodiments of the present invention, the lubricating oil switching device further includes an oil inlet pipe 57 and an oil outlet pipe 58. The inlet of the oil inlet pipe 57 is connected to the lubrication point 12, and the outlet of the oil inlet pipe 57 is connected to the oil return port connected to the seventh space 53. The outlet of the oil outlet pipe 58 is connected to the oil supply pump group 10, and the inlet of the oil outlet pipe 58 is connected to the oil outlet connected to the seventh space 53.

[0047] In some embodiments of the present invention, the result of the lubricating oil quality acquisition device can be used to determine whether the lubricating oil needs to be cleaned. The result of the lubricating oil quality acquisition device can also be used to determine whether the cleaning of the lubricating oil cleaning device 20 is completed.

[0048] In some embodiments of the present invention, in the process of the lubricating oil in the cleaning oil tank 42 entering the oil supply tank 31 and entering the oil supply pump group 10, the flow rate can be adjusted according to the temperature of the lubricating oil entering the oil supply tank 31 from the lubrication point 12, so as to mix the hot and cold oils and cool the return oil from the lubrication point 12. Specifically, in some embodiments of the present invention, a temperature sensor is provided on the oil inlet manifold to detect the temperature of the lubricating oil returned from the lubrication point 12. A flow regulating valve is provided at the outlet of the sixth space 47, that is, the flow regulating valve is provided between the outlet of the sixth space 47 and the fourth connecting port. In other embodiments of the present invention, a temperature sensor is provided at the oil return port connected to the seventh space 53 to detect the temperature of the lubricating oil returned from the lubrication point 12. A flow regulating valve is provided on the connecting pipe between the tenth space 56 and the seventh space 53.

[0049] In the embodiment of the present invention, when the lubricating oil in the clean oil tank 42 is needed for lubrication, the lubricating oil in the clean oil tank 42 gradually enters the oil supply tank 31. At this time, the oil supply tank 31 also receives the lubricating oil returned from the lubrication point 12. By controlling the amount of oil from the clean oil tank 42 entering the oil supply tank 31, the lubricating oil returned from the oil supply tank 31 is cooled down, and the mixing of hot and cold oils is beneficial to the cooling of the lubricating oil. Although in this embodiment, the cleaned lubricating oil does not enter the oil supply tank 31 temporarily, the returned lubricating oil plus the lubricating oil used for cooling can also meet the lubrication needs of the lubrication point 12.

[0050] In some embodiments of the present invention, Figure 6As shown, the lubricating oil cleaning device 20 includes a first oil pump 25, a multi-layer filter device and a second oil pump 26. The outlet of the first oil pump 25 is connected to the inlet of the multi-layer filter device, and the inlet of the second oil pump 26 is connected to the outlet of the multi-layer filter device. By controlling the first oil pump 25 and the second oil pump 26, the pressure of the lubricating oil in the multi-layer filter device can be controlled, so that the lubricating oil can pass through the multi-layer filter device smoothly. The multi-layer filter device includes a filter housing 27, a plurality of filter plates 28 and a plurality of push plates 29. The filter housing 27 contains a filter cavity; the top of the filter housing 27 is provided with an inlet, and the bottom is provided with an outlet. A plurality of filter plates 28 are sequentially arranged in the filter cavity along the up and down directions; one end of each filter plate 28 is higher than the other end of the filter plate 28. Each push plate 29 is arranged on the upper side of a filter plate 28, and is arranged to move up and down along the upper surface of the filter plate 28. The push plate 29 is movably arranged, and can stir the lubricating oil on the upper side of each filter plate 28, while preventing impurities from gathering at the lower end of the filter plate 28, so as to facilitate the downward filtering and flow of the lubricating oil. In every two adjacent filter plates 28, the filtering accuracy of the upper filter plate 28 is less than that of the lower filter plate 28, that is, in every two adjacent filter plates 28, the upper filter plate 28 is for coarse filtering, and the lower filter plate 28 is for fine filtering. Each filter plate 28 is evenly distributed with filtering holes, and the corresponding push plate 29 is also provided with filtering holes of corresponding size.

[0051] The embodiment of the present invention further provides a filtering method for the lubrication filtering system for a cone crusher in any of the above embodiments, comprising: The lubricating oil quality obtaining device is used to obtain the quality of the lubricating oil in the oil tank; According to the quality of the lubricating oil, a corresponding part of the lubricating oil in the two oil tanks is cleaned by the lubricating oil cleaning device 20, and the remaining lubricating oil in the two oil tanks is supplied to the lubrication point 12 on the cone crusher through the oil supply pump group 10.

[0052] In the embodiment of the present invention, by detecting the quality of the lubricating oil, when the lubricating oil needs to be cleaned, another part of the clean lubricating oil is used to enter the lubrication point 12 on the cone crusher for lubrication, and the lubricating oil that needs to be cleaned is cleaned, thereby significantly improving the service life of the lubricating oil. At the same time, in the embodiment of the present invention, two oil tanks are used, each of which can be filled with lubricating oil, and there is no need to set up a special oil tank for cleaning the lubricating oil, which is small in size.

[0053] In some embodiments of the present invention, the filtering method of the lubrication filtering system for a cone crusher further comprises: Acquire the temperature of the lubricating oil returned from the lubrication point 12 to the oil supply tank 31; The flow regulating valve is controlled according to the temperature of the lubricating oil to control the flow of the lubricating oil provided by the clean oil tank 42 to the oil supply tank 31, thereby mixing and cooling the lubricating oil from the lubrication point 12 in the oil supply tank 31 to meet the lubrication demand of the lubricating oil.

[0054] In the embodiment of the present invention, the cooling capacity of the clean lubricating oil can be fully utilized and mixed with the returned lubricating oil to reduce the temperature of the lubricating oil as quickly as possible, thereby significantly improving the cooling effect of the lubricating oil and ensuring the lubricating effect.

[0055] In some embodiments of the present invention, the filtering method of the lubrication filtering system for a cone crusher further comprises: When the lubricating oil cleaning device 20 needs to be started, the initial value of the rotation speed of the first oil pump 25, the initial value of the rotation speed of the second oil pump 26, the initial value of the oil delivery speed of the second oil pump 26 and the initial value of the speed at which the push plate 29 moves along the upper surface of the corresponding filter plate 28 are determined according to the quality of the lubricating oil to be cleaned; The first oil pump 25 and the second oil pump 26 are started according to the respective initial values, and the push plate 29 is controlled to move along the upper surface of the corresponding filter plate 28 at the same time; Obtaining the oil delivery speed of the second oil pump 26; When the oil delivery speed of the second oil pump 26 decreases and is less than the initial value, the rotation speed of the first oil pump 25 is reduced, and the rotation speed of the second oil pump 26 is increased to reduce the oil delivery speed of the first oil pump 25; at the same time, the moving speed of the push plate 29 is increased; When the oil delivery speed of the second oil pump 26 is restored to the initial value, the rotation speed of the first oil pump 25 is restored to the initial value, the rotation speed of the second oil pump 26 is restored to the initial value, and the moving speed of the push plate 29 is restored to the initial value; When the oil delivery speed of the second oil pump 26 increases and is greater than the initial value, the rotation speed of the first oil pump 25 is increased, and the rotation speed of the second oil pump 26 is increased until the oil delivery speed of the second oil pump 26 stops increasing.

[0056] The oil delivery speed of the second oil pump 26 at this time is taken as the initial value of the oil delivery speed, the rotation speed of the first oil pump 25 is taken as the initial value of the rotation speed of the first oil pump 25 , and the rotation speed of the second oil pump 26 is taken as the initial value of the rotation speed of the second oil pump 26 .

[0057] In the embodiment of the present invention, the lubricating oil cleaning device 20 can automatically adjust the cleaning speed according to the quality of the lubricating oil to be cleaned, thereby improving the cleaning efficiency of the lubricating oil cleaning device 20 for the lubricating oil and completing the cleaning of the lubricating oil as quickly as possible. Specifically, for lubricating oil that is difficult to filter, the oil inlet speed of the multi-layer filtering device is reduced, and the power and stirring speed of the oil outlet are increased, so that the lubricating oil passes through the multi-layer filtering device as quickly as possible, ensuring efficient filtration and improving the filtration speed. For lubricating oil that is relatively easy to filter, the initial values ​​of various parameters are automatically adjusted to complete the filtration as quickly as possible.
