Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic oil purification, and in particular to an external hydraulic oil purification device for a hydraulic station. Background Art

[0002] A hydraulic station is a device that converts mechanical energy into hydraulic energy. It consists of an electric motor, oil pump, oil tank, valves, piping, and control components. Its primary function is to provide power for various hydraulic systems and is widely used in industrial manufacturing, construction machinery, aerospace, and marine applications. Hydraulic oil is the working medium that transmits energy in hydraulic systems and provides lubrication, cooling, sealing, and rust prevention functions.

[0003] After long-term use, various impurities will exist in the hydraulic oil, which will affect the working efficiency and reliability of the hydraulic system in the hydraulic station. The common treatment method is to replace the hydraulic oil as a whole, but this method is not only time-consuming and labor-intensive, but also prone to waste of resources. Therefore, a better treatment method is to purify the hydraulic oil in real time while using it to achieve the effect of recycling. However, when the existing hydraulic oil purification treatment device absorbs and treats metal impurities in the hydraulic oil, it is difficult to ensure that the hydraulic oil is in uniform and comprehensive contact with the magnet, so that the metal impurities are only accumulated in some areas of the magnet. As the amount of accumulation gradually increases, it will also affect the magnet's adsorption effect on subsequent metal impurities, resulting in poor overall purification treatment effect of the device.

[0004] Based on the above situation, the present invention proposes an external hydraulic oil purification device for a hydraulic station with good purification effect. Summary of the Invention

[0039] Example 1: An external hydraulic oil purification device for a hydraulic station, such as Figures 1-9As shown, it includes an installation box 1, a rotating cylinder 11, a power component 12, an electromagnet block 13, a heating plate 14, a liquid pump 15, an external connector 16, a guide pipe 17, a reciprocating screw 18, a mobile nozzle 19, a transmission belt 110, a flexible cylinder sleeve 111, a current limiting plate 112, a magnetic collection bucket 113 and a pressure rod 114, wherein the installation box 1 is provided with purification chambers on both sides, the left side of the installation box 1 is rotatably connected to the rotating cylinder 11, the left side of the installation box 1 is connected to the power component 12, the power component 12 is transmission-connected to the rotating cylinder 11, and is used to drive the rotating cylinder 11 to rotate, the left side of the installation box 1 is fixedly connected to the electromagnet block 13, the electromagnet block 13 is rotatably connected to the rotating cylinder 11, the right side of the installation box 1 is fixedly connected to the heating plates 14 vertically staggered in the upper and lower directions, the interior of the installation box 1 is fixedly connected to the liquid pump 15, and the left and right ends of the liquid pump 15 are respectively connected to the purification chambers on the left and right sides of the installation box 1. An external connector 16 is fixed to the upper left side of the body 1, and a reciprocating screw 18 is rotatably connected to the left side of the installation box 1. A mobile nozzle 19 is slidably connected to the left side of the interior of the installation box 1, and the mobile nozzle 19 is threadedly connected to the reciprocating screw 18. A guide pipe 17 is fixedly connected and communicated between the mobile nozzle 19 and the external connector 16, wherein the guide pipe 17 is made of flexible rubber material, and two transmission belts 110 symmetrically distributed front and back are sleeved between the reciprocating screw 18 and the rotating cylinder 11. A flexible cylinder sleeve 111 is fixed to the outside of the rotating cylinder 11, and a limiting flow plate 112 is fixed to the lower side of the interior of the installation box 1. The upper part of the limiting flow plate 112 is slidably connected to the installation box 1, and the limiting flow plate 112 contacts and cooperates with the flexible cylinder sleeve 111. A magnetic collecting bucket 113 is clamped on the left side of the installation box 1, and the magnetic collecting bucket 113 contacts and cooperates with the flexible cylinder sleeve 111. A pressure rod 114 is fixed to the right side of the mobile nozzle 19, and the pressure rod 114 is slidably connected to the limiting flow plate 112.

[0040] like Figure 6 and Figure 7 As shown, a wave-shaped sliding groove is opened on the upper part of the flow limiting plate 112.

[0041] When the worker needs to purify the hydraulic oil, he can first connect the hydraulic oil output pipe to the external connector 16, then start the power assembly 12 and the electromagnet block 13 and gradually inject the hydraulic oil into the external connector 16. The hydraulic oil in the external connector 16 will enter the mobile nozzle 19 through the guide pipe 17, and then spray out from the bottom of the mobile nozzle 19 and enter the purification chamber on the left side of the installation box 1. The power assembly 12 will drive the rotating cylinder 11 and the flexible cylinder sleeve 111 to rotate clockwise. The clockwise rotation of the rotating cylinder 11 will also drive the reciprocating screw 18 to rotate clockwise through the transmission belt 110. The clockwise rotation of the reciprocating screw 18 will drive the mobile nozzle 19 to move back and forth, so that the mobile nozzle 19 can spray the hydraulic oil evenly. The hydraulic oil is then sprayed onto the flexible sleeve 111, and the flexible sleeve 111 will evenly absorb the metal impurities in the hydraulic oil under the action of the electromagnet block 13. During this period, the moving nozzle 19 will move back and forth and will also drive the pressure rod 114 to move back and forth. The pressure rod 114 will first move to the crest of the wave-shaped groove on the upper part of the flow-limiting piece 112, and make the upper part of the flow-limiting piece 112 move downward, and the middle part of the flow-limiting piece 112 will immediately deform and fold downward. At this time, the middle protrusion of the flow-limiting piece 112 will move to the left under the action of the deformation and press against the flexible sleeve 111, thereby blocking the hydraulic oil from flowing downward along the flexible sleeve 111, and when the pressure rod 114 moves to the trough of the wave-shaped groove on the upper part of the flow-limiting piece 112, the upper part of the flow-limiting piece 112 will be deformed and folded downward. The hydraulic oil can then continue to flow downward along the flexible sleeve 111, thereby enabling the hydraulic oil to flow downward intermittently, thereby ensuring that the flexible sleeve 111 and other components can fully absorb the metal impurities in the hydraulic oil, thereby avoiding the omission of some metal impurities due to the excessive flow rate of the hydraulic oil, thereby improving the purification effect of the device. In the clockwise rotation process of the flexible sleeve 111, the magnetic collection bucket 113 can scrape off and collect the metal impurities absorbed on the surface of the flexible sleeve 111, thereby avoiding the accumulation of metal impurities on the surface of the flexible sleeve 111 and affecting the absorption of subsequent metal impurities by the flexible sleeve 111 and other components. Effect: when enough metal impurities are collected in the magnetic collecting bucket 113, the magnetic collecting bucket 113 can be removed from the installation box 1 and cleaned. The hydraulic oil that has been adsorbed and purified by the flexible sleeve 111 and other components will fall to the bottom of the left cavity of the installation box 1. At this time, the liquid pump 15 and the heating plate 14 can be started. The liquid pump 15 will transport the hydraulic oil at the bottom of the left cavity to the right purification cavity of the installation box 1. When the hydraulic oil enters the right purification cavity, it will flow downward along the three staggered heating plates 14. The heating plate 14 can heat the hydraulic oil and evaporate the moisture in the hydraulic oil, thereby improving the quality of the hydraulic oil. The purified hydraulic oil will eventually be discharged from the discharge port at the lower right corner of the right purification cavity and recycled.

[0042] Example 2: On the basis of Example 1, Figure 10 and Figure 11 As shown, a separation mechanism is also included, which is arranged on the installation box 1. The separation mechanism includes a guide plate 2, a placement rack 21, an arc-shaped ruler 22, a screw 23, a guide rod 24, a slider 25 and a connecting block 26. The placement rack 21 is slidably connected to the right part of the installation box 1, and the bottom left side of the placement rack 21 is rotatably connected to the guide plate 2. The lower left side of the placement rack 21 is fixed with two arc-shaped rulers 22 symmetrically distributed front and back, and the arc-shaped ruler 22 is slidably connected to the guide plate 2. The right front side of the placement rack 21 is threadedly connected to the screw 23, and the bottom end of the screw 23 is rotatably connected to the connecting block 26. The right rear side of the placement rack 21 is slidably connected to the guide rod 24, and the bottom end of the guide rod 24 is fixed with the connecting block 26. The bottom of the connecting block 26 is rotatably connected to the slider 25, and the slider 25 is slidably connected to the guide plate 2.

[0043] like Figure 10 and Figure 11 As shown, the top of the guide plate 2 is provided with axially distributed protrusions.

[0044] When the hydraulic oil enters the right purification chamber of the installation box 1 under the action of the liquid pump 15, the hydraulic oil will fall on the guide plate 2 and flow downward along the guide plate 2. Since some impurities in the hydraulic oil have a high density, the impurities with high density will gradually sink as the hydraulic oil flows until they are blocked by the axially distributed protrusions on the top of the guide plate 2, and the hydraulic oil can flow smoothly downward along the guide plate 2. In this way, the impurities with high density in the hydraulic oil can be separated with the help of the guide plate 2, thereby improving the purification effect of the device. Before placing the components, the worker can also lift the placement rack 21, the guide plate 2 and other components upwards, and drive the guide rod 24, the connecting block 26 and other components to move upwards or downwards by rotating the screw 23. The upward or downward movement of the connecting block 26 will also drive the guide plate 2 and the slider 25 to rotate counterclockwise or clockwise, and the slider 25 will then slide left or right on the guide plate 2, so that the guide plate 2 can be adjusted to a suitable angle to facilitate better deposition of impurities on the guide plate 2. The presence of the arc ruler 22 helps workers to accurately adjust the inclination angle of the guide plate 2.

[0045] like Figure 12-14 As shown, a deceleration mechanism is also included, which is arranged on the liquid pump 15. The deceleration mechanism includes a storage bucket 3, a pull rope 31, a baffle 32 and a spring piece 33. The storage bucket 3 is fixedly connected to and connected to the right end of the liquid pump 15. A discharge trough is provided at the lower right side of the storage bucket 3. A baffle 32 is slidably connected to the inside of the right side of the storage bucket 3. Two spring pieces 33 symmetrically distributed front and back are fixedly connected between the baffle 32 and the storage bucket 3. Two pull ropes 31 symmetrically distributed front and back are fixedly connected between the baffle 32 and the current limiting plate 112. The pull rope 31 is slidably connected to the mounting box 1.

[0046] When the hydraulic oil enters the right side purification chamber of the installation box 1 under the action of the liquid pump 15, the hydraulic oil will first enter the storage bucket 3. At this time, the baffle 32 will block the discharge chute on the right side of the storage bucket 3 to prevent the hydraulic oil from flowing out. When the flow limiting piece 112 is deformed under the action of the pressure rod 114, the flow limiting piece 112 will pull the pull rope 31, and the baffle 32 will move upward through the pull rope 31. The spring piece 33 is then compressed, and the hydraulic oil can flow out along the discharge chute on the right side of the storage bucket 3 and It falls on the guide plate 2, and when the flow limiting piece 112 returns to its original state, the pull rope 31 is loosened, and the baffle 32 moves downward under the action of its own gravity and the elastic force of the spring piece 33 to reset and re-block the discharge slot on the right side of the storage bucket 3, so that the hydraulic oil can intermittently flow from the storage bucket 3 to the guide plate 2, thereby reducing the flow speed of the hydraulic oil on the guide plate 2, so that the impurities inside the hydraulic oil have sufficient time to settle downward on the guide plate 2, thereby improving the impurity removal effect.

[0047] like Figure 15 and Figure 16 As shown, it also includes a filtering mechanism, which is arranged in the installation box 1. The filtering mechanism includes a filter screen 4, a gear ring 41 and a vibration-guided block 42. The filter screen 4 is slidably connected to the lower left part of the installation box 1, wherein the filter screen 4 is inclined. Two gear rings 41 symmetrically distributed front and back are fixed to the outside of the rotating cylinder 11, and two vibration-guided blocks 42 symmetrically distributed front and back are fixed to the top of the filter screen 4. The vibration-guided block 42 is squeezed and fitted with the adjacent gear ring 41.

[0048] like Figure 15 and Figure 16 As shown, the vibration-guiding block 42 is made of elastic material.

[0049] When the hydraulic oil flows downward along the flexible cylinder sleeve 111, the hydraulic oil will also pass through the filter 4, and the filter 4 can separate the non-metallic impurities in the hydraulic oil. When the rotating cylinder 11 rotates clockwise under the action of the power assembly 12, the gear ring 41 will also rotate clockwise with the rotating cylinder 11. The clockwise rotation of the gear ring 41 will first contact and squeeze the vibration guide block 42, and the vibration guide block 42 will then deform. When the gear ring 41 rotates to separate from the vibration guide block 42, the vibration guide block 42 will return to its original shape under the action of its own elasticity. Therefore, as the gear ring 41 continues to rotate, the vibration guide block 42 will continuously deform back and forth and reset and generate vibration, thereby driving the filter 4 to vibrate continuously, so that the non-metallic impurities on the filter 4 are accumulated along the inclined surface of the filter 4 in the lower left corner, avoiding the non-metallic impurities from completely clogging the filter 4 and affecting the filtering effect. When a large amount of non-metallic impurities accumulate on the filter 4, the worker can pull the filter 4 forward and clean it.

[0050] like Figure 1 and Figure 17As shown, a sampling mechanism is also included, which is arranged in the installation box 1. The sampling mechanism includes a placement plate rack 5 and a collection tube 51. The placement plate rack 5 is slidably connected to the right side of the installation box 1, and the placement plate rack 5 is slidably connected to the left side with three collection tubes 51 distributed longitudinally in the front and back.

[0051] When the hydraulic oil is purified and flows downward along the lowest heating plate 14, the collection tube 51 on the plate rack 5 can perform multi-area sampling of the hydraulic oil. After the sampling is completed, the worker can pull the plate rack 5 and the collection tube 51 to the right. After testing the sampled samples, the worker can understand the quality of the purified hydraulic oil and adjust the inclination angle of the guide plate 2 to ensure that the quality of the purified hydraulic oil meets the expected requirements.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
