Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrostatic equipment, in particular, to a hydrostatic turntable device. BACKGROUND

[0002] At present, the hydrostatic turntable device as a kind of precision mechanical parts plays an important role in industrial production, and its working principle relies on the static pressure of oil to realize the stable rotation of the turntable. In the operation process of the hydrostatic turntable, the oil not only plays a role of lubrication and cooling, but also transmits the necessary static pressure. However, with the circulation of oil in the system, its quality will gradually decrease, containing impurities and wear particles, which will adversely affect the performance and service life of the turntable.

[0003] After searching, it is found that the Chinese patent with the authorization announcement number CN116255398B discloses a hydrostatic turntable device. The patent contains an oil supply assembly, which supplies oil through an oil inlet pipe and discharges oil through an oil outlet pipe, and sets two groups of filter assemblies that can filter the discharged waste oil in turn, and a flushing pipe for cleaning the filter assemblies and an oil discharge pipe for discharging waste oil, realizing the continuous work of the hydrostatic turntable. However, the patent only filters the discharged oil, and the new oil also needs to be filtered before being added to the system to ensure its purity, especially when new oil and old oil are used together, strict filtration is needed in the oil inlet stage to prevent impurities from damaging the system. In the oil discharge process, in order to remove impurities in the oil, the patent uses the backwashing method. Although this method is effective, it is complicated to operate, and whether using new oil or cleaning agent for backwashing will increase additional cost and time. In addition, the existing backwashing device has the disadvantage of being unable to avoid blockage, and cannot directly clean the larger impurities filtered out in the oil discharge process, which further limits its application effect. At the same time, the oil inlet part and the oil discharge part also need to be filtered in different ways. The oil inlet part should use a lower precision filtration method to reduce resistance due to fewer impurities, while the oil discharge part needs higher filtration precision to remove more impurities and pollutants.

[0047] The conveying chamber is connected with the main storage tank, and the main storage tank is connected with the oil pump.

[0048] The above technical scheme has the following beneficial effects:

[0049] 1. By arranging the oil inlet filter component and the oil discharge filter component, the oil in the oil inlet pipe and the oil discharge pipe is filtered according to the different amounts of impurities, and two groups of the oil inlet filter component and the oil discharge filter component are arranged, which can work simultaneously or alternately, and the filter component in the idle state can start the self-cleaning mode to ensure the filtering effect.

[0050] 2. Through the arrangement of structures such as a rotatable oil inlet filter and a separator cylinder, when the oil inlet filter component is in working condition, the separator cylinder is in the oil inlet filter chamber, dividing the oil inlet filter chamber into an inner chamber and an outer chamber. The oil contacts the oil inlet filter in the inner chamber and is filtered. When the oil inlet filter component is in a self-cleaning state, the separator cylinder moves to the oil inlet lower shell, so that the inner chamber and the outer chamber are communicated. The oil inlet filter is driven to rotate and the impurities attached to its surface are thrown into the outer chamber through the centrifugal force generated by rotation to achieve self-cleaning. After cleaning is completed, the separator cylinder is reset. Since the oil in the oil inlet part contains fewer impurities, a simpler and more efficient self-cleaning method is adopted.

[0051] 3. Through the setting of structures such as the oil inlet filter and the adjustment filter, transverse grooves are opened on both the oil inlet filter and the adjustment filter. The transverse grooves on the two are staggered to form oil holes for filtering oil. When the static pressure turntable body urgently needs to supply oil quickly to maintain stability, the oil injection can be increased. The increase in oil pressure can drive the adjustment filter to produce an angular offset, thereby increasing the size of the oil hole. The resistance to the oil is reduced while reducing the filtering accuracy, allowing the oil to pass quickly and enter the interior of the static pressure turntable body, thereby improving the ability to respond to emergencies.

[0052] 4. Through the arrangement of the longitudinal moving assembly and the cleaning plate and other structures, when the oil drain filter component is in the self-cleaning state, air is ventilated into the air inlet cylinder in the longitudinal filter component to push the matching rod to move, and the matching rod drives the slider to move in the slide rail, and the slider drives the cleaning plate to move on the outer surface of the oil drain filter, thereby scraping off a large amount of impurities attached to the oil drain filter. Since the oil drain filter filters the used oil, the impurities in the used oil are large and difficult to clean, so the scraping method is adopted to further improve the self-cleaning effect.

[0053] 5. Through the arrangement of structures such as horizontal air outlet holes and downward inclined air outlet holes, when the air inlet cylinder is ventilated, most of the gas squeezes the matching rod to realize the movement of the cleaning plate, but part of the gas will enter the interior of the slider and the cleaning plate through the air inlet hole on the matching rod, and flow out from the horizontal air outlet holes and downward inclined air outlet holes on the cleaning plate. The function of the horizontal air outlet hole is to blow air in the horizontal direction to directly clear the holes on the oil drain filter to avoid blockage. The air from the downward inclined air outlet blows air on the outer surface of the oil drain filter, blowing the impurities on the surface down to the matching cleaning plate to process the impurities on the surface.

[0054] 6. Through the arrangement of the first inclined plate and the second inclined plate and other structures, the first inclined plate moves with the cleaning plate. When the cleaning plate has completely cleaned the outer surface of the oil drain filter, the first inclined plate squeezes the second inclined plate, forcing the second inclined plate to move, so that the space between the oil drain filter chamber and the receiving plate is opened. At this time, the impurities scraped off the cleaning plate will fall into the receiving plate, achieving the effect of automatic collection and processing of impurities, avoiding clogging of the oil drain filter while discharging the impurities, and further reducing the risk of clogging of the oil drain filter.

[0055] 7. Through the arrangement of structures such as the power impeller and the stirring rod arranged perpendicularly to each other in the axial direction, the oil treated by the oil discharge and filtering components enters the old oil storage tank, and the new oil is placed in the new oil storage tank. Both of them pass the oil inside into the pre-mixing chamber. The oil outlet of the new oil storage tank is twice that of the old oil storage tank. Therefore, when the old oil and the new oil are mixed into the pre-mixing chamber, the ratio of the old oil to the new oil is 1:2. After being stirred and mixed in two directions by the power impeller and the stirring rod, they enter the main storage tank and are sent into the oil inlet pipe by the oil pump. The stable mixing of the new oil and the old oil is more comprehensive through a certain proportion. While ensuring the oil quality, the stratification phenomenon of the oil film after entering the static pressure turntable body caused by the uneven new and old oils is also avoided.

[0108] The oil in the oil tank 14 is pumped out by the oil pump 11 into the oil inlet pipe 12 and filtered by the oil inlet filtering part 3, and then enters the static pressure turntable body 2 to form an oil film to support the turntable. The oil in the static pressure turntable body 2 is discharged after a long time of use through the oil discharge pipe, and the discharged old oil is filtered by the oil discharge filtering part 4. The filtered old oil and new oil can be recycled after being mixed in a certain proportion. It should be noted that a throttle valve (not shown in the figure) is connected to the output end of the oil pump 11. The throttle valve can adjust the pressure of the oil pumped by the oil pump 11 into the oil inlet pipe 12 according to the needs, so that the static pressure turntable body 2 can deliver constant and stable oil, and the generated oil film can play a normal role. The throttle valve and the static pressure turntable body 2 are both prior art, and their working principles will not be described in detail here.

[0109] The oil inlet filtering part 3 and the oil discharge filtering part 4 are both provided with two groups. The two oil inlet filtering parts 3 can work simultaneously or alternately. The oil inlet filtering part 3 in the non-working state can perform self-cleaning work. The oil discharge filtering part 4 works in the same way. The work can be connected and disconnected through the corresponding electric control valve.

[0110] When the oil enters the oil inlet filtering part 3, it first enters the oil inlet upper housing 31. The internal space of the oil inlet upper housing 31 is divided into an oil inlet port and a mounting chamber by the blocking plate 34. The oil enters the oil inlet filtering cavity 313 in the oil inlet filtering chamber 32 from the oil inlet port. At this time, the separation cylinder 312 is located in the oil inlet filtering cavity 313, which divides the oil inlet filtering cavity 313 into an inner cavity and an outer cavity. The oil enters the inner cavity from the oil inlet port and contacts the oil inlet filtering screen 36. The oil is filtered through the inside of the oil inlet filtering screen 36. The filtered oil leaves the oil inlet filtering part 3 through the oil inlet lower housing 33.

[0111] When the oil inlet filter part 3 needs to be self-cleaning, the drive motor 35 is started to reverse, the output shaft of the drive motor 35 drives the oil inlet filter screen 36 to reverse as a whole, and in the process, the output shaft drives the connecting rod 38, the one-way bearing 310 and the reciprocating screw rod 39 to rotate through the synchronous belt 37. When the reciprocating screw rod 39 rotates, the transmission sleeve 311 assembled outside the reciprocating screw rod 39 moves along the axis direction of the reciprocating screw rod 39. At this time, it is moving towards the oil inlet lower shell 33. It should be noted that the connection relationship between the transmission sleeve 311 and the reciprocating screw rod 39 is prior art and will not be described in detail here. When the transmission sleeve 311 moves towards the oil inlet lower shell 33, it drives the partition cylinder 312 connected thereto to move into the oil inlet lower shell 33. The oil inlet lower shell 33 is provided with a sliding groove. At this time, the partition of the partition cylinder 312 is lost, and the inner cavity and the outer cavity are communicated. A guide rod 314 is also arranged in the sliding groove. The partition cylinder 312 will slide outside the guide rod 314 during movement. The guide rod 314 plays a role in improving stability. When the partition cylinder 312 completely enters the sliding groove, the drive motor 35 stops reversing and switches to forward rotation. The output shaft under forward rotation drives the oil inlet filter screen 36 to rotate as a whole and drives the connecting rod 38 to rotate through the synchronous belt 37. However, due to the arrangement of the one-way bearing 310, the reciprocating screw rod 39 will not rotate at this time, that is, the partition cylinder 312 is still located in the sliding groove at this time. In the process, the oil inlet filter screen 36 is driven to rotate all the time, thereby generating centrifugal force to throw the impurities attached to its surface into the outer cavity, thereby achieving the effect of self-cleaning. Since the oil entering the oil inlet filter part 3 is divided into two types, one is new oil without pollution and the other is mixed oil of new oil and old oil, and the old oil is filtered by the oil discharge filter part 4 when it is discharged through the oil discharge pipe, therefore, no matter which type it is, there will be no too many impurities, therefore, the filtering precision requirement of the oil inlet filter screen 36 is not high, and a simple arrangement can reduce the resistance of oil inlet. At the same time, the impurities filtered out are not too many, and do not need too complicated self-cleaning mode. Regularly rotating the mode can transfer the impurities to the outer cavity. When the oil inlet filter screen 36 under forward rotation completes the self-cleaning work, the drive motor 35 is switched from forward rotation to reverse rotation again. The output shaft under reverse rotation drives the reciprocating screw rod 39 to rotate again, thereby driving the partition cylinder 312 located in the sliding groove to reset to the oil inlet filter cavity 313, continuing to separate the oil inlet filter cavity 313, separating the inner cavity for filtering and the outer cavity for storing impurities. It should be noted that the entire self-cleaning work of the oil inlet filter screen 36 is carried out in the state of oil cut-off, and the drive motor 35 drives the oil inlet filter screen 36 to rotate whether it is forward rotation or reverse rotation, but it has no effect on the overall self-cleaning work. In order to avoid oil entering the installation chamber, a rotary seal can be arranged on the reciprocating screw rod 39 and the output shaft of the drive motor 35. After the self-cleaning work is completed, the partition cylinder 312 is in the oil inlet filter cavity 313, the upper surface thereof abuts against the oil inlet upper shell 31, and the lower surface thereof abuts against the oil inlet lower shell 33, so that the inner cavity is in a sealed state.At this time, no matter whether there is oil in the inner cavity for filtering, the impurities stored in the outer cavity can be manually cleaned by opening the first disassembly plate 321, which will not affect the normal filtering work. The above arrangement cleans the oil inlet filter 36 at the oil inlet, and the whole working process is simple and efficient. It is mainly designed for the oil at the oil inlet to have less impurities.

[0112] In addition, the oil hole on the oil inlet filter 36 for allowing oil to pass through and achieve a filtering effect is not a fixed size setting, but is adjusted by rotating the adjustment filter 316 set in the oil inlet filter 36. The oil inlet filter 36 and the adjustment filter 316 are both provided with transverse grooves of the same size. The transverse grooves on the oil inlet filter 36 and the transverse grooves on the adjustment filter 316 are staggered to form an oil hole. It should be noted that the outer surface of the adjustment filter 316 needs to fit with the inner wall of the oil inlet filter 36. In the initial state, the oil hole formed by the adjustment filter 316 and the oil inlet filter 36 is the smallest in size, and the filtration accuracy is also the highest. When an emergency occurs and the static pressure turntable body 2 needs to supply oil quickly to maintain stability, the fixed oil hole has unchanged resistance to oil, and forcibly accelerating the oil supply will damage the oil inlet filter 36. Therefore, under the setting of the rotatable adjustable filter 316, when rapid oil supply is needed, the oil accelerates to pass through the oil hole and squeezes the adjustable filter 316 to a certain extent. The squeezed adjustable filter 316 will squeeze the telescopic rod 1 319 and the spring 1 320 to cause a position deviation. Due to the angular deviation of the adjustable filter 316, the transverse grooves thereon are also offset. At this time, the size of the oil hole formed by the staggered transverse grooves on the oil inlet filter 36 and the adjustable filter 316 will also become larger, allowing the oil to pass through quickly while sacrificing a certain filtering accuracy, so as to achieve rapid oil supply to respond to emergencies without damaging the oil inlet filter 36. When the emergency oil supply is completed, the normal oil inlet speed is restored, and the adjustable filter 316 will not be squeezed. At this time, the adjustable filter 316 is reset by the telescopic rod 1 319 and the spring 1 320.

[0120] The telescopic rod two 415 is connected with the inner wall of the sliding groove 430 and the connecting seat 413 at two ends respectively, and the outer part of the telescopic rod two 415 is sleeved with the spring two 416, and the two ends of the spring two 416 are connected with the inner wall of the sliding groove 430 and the connecting seat 413 respectively;

[0121] The first inclined plate 410 is provided with a blocking surface 424 which is perpendicular to the bottom surface of the cleaning plate 49 and is located at one end close to the oil discharge filter screen 46, and the blocking surface 424 is suitable for limiting the position of impurities scraped off from the surface of the oil discharge filter screen 46 by the cleaning plate 49;

[0122] In the initial state, one end of the second inclined plate 412 close to the oil discharge filter screen 46 is in abutment with the outer surface of the oil discharge filter screen 46, and the upper surface of the connecting seat 413 is in abutment with the inner wall of the groove 431, and the second inclined plate 412 and the connecting seat 413 are suitable for closing the channel connecting the oil discharge filter chamber 43 and the internal space of the storage plate 44 in the initial state;

[0123] The first inclined plate 410 is suitable for moving along with the cleaning plate 49, thereby causing the second inclined plate 412 to be extruded and moving the second inclined plate 412 and the corresponding connecting seat 413 in the sliding groove 430 away from the oil discharge filter screen 46, so that the oil discharge filter chamber 43 and the internal space of the storage plate 44 are communicated, the blocking surface 424 and the cleaning plate 49 are located above the storage cavity, and the impurities accumulated on the cleaning plate 49 and the blocking surface 424 fall into the storage cavity;

[0124] The bottom of the storage plate 44 is detachably provided with a second detachable plate 411 which is communicated with the inside of the storage cavity.

[0125] As shown in Figure 11 , Figure 13 The oil discharge upper shell 41 is provided with a magnetic suction cone barrel 45, and the magnetic suction cone barrel 45 is suitable for adsorbing part of metal substances in the oil entering the oil discharge upper shell 41;

[0126] The oil discharge filter chamber 43 is provided with a mounting seat 427, a plurality of mounting grooves are formed in the mounting seat 427, the bottom of the oil discharge filter screen 46 is inserted into the mounting grooves, the top of the oil discharge filter chamber 43 is detachably provided with a pull cover plate 426, the top of the oil discharge filter screen 46 is connected with the pull cover plate 426, and the bottom of the pull cover plate 426 is provided with a plurality of auxiliary filter screens 425 which are arranged at intervals, the bottom of the auxiliary filter screen 425 is inserted into the corresponding mounting groove, and the pull cover plate 426 is suitable for being disconnected with the oil discharge filter chamber 43 to drive the auxiliary filter screen 425 and the oil discharge filter screen 46 to be pulled out to the inside of the oil discharge filter chamber 43.

[0127] The working principle of the embodiment is as follows:

[0128] In the oil discharge work time static pressure turntable main part 2 in the oil passes through the oil discharge pipe and enters the oil discharge filter component 4, first enter the oil discharge upper casing 41, be provided with magnetic attraction cone barrel 45 in the oil discharge upper casing 41, magnetic attraction cone barrel 45 is conical setting, and is magnetic attraction material, the metal substance in the old oil of entering is adsorbed, and the effect of pre-filtering is played;

[0129] The oil that is filtered through the oil discharge filter screen 46 finally leaves the inside of the oil discharge filter chamber 43 from the bottom of the oil discharge filter chamber 43 and exits the inside of the oil discharge filter component 4;

[0130] The oil discharge filter screen 46 will have a large amount of impurities attached to its surface after long-term use. Since the oil filtered by the oil discharge filter screen 46 is old oil used by the static pressure turntable main part 2, there are many impurities, and the workload is large. The impurities attached to the surface of the oil discharge filter screen 46 are easily clogged. Therefore, a longitudinal movement assembly is provided to drive the cleaning plate 49 to move longitudinally on the surface of the oil discharge filter screen 46, and a large amount of impurities attached to the surface of the oil discharge filter screen 46 are removed by scraping;

[0131] When the oil discharge filter screen 46 needs to be self-cleaned, compressed gas is introduced into the air inlet cylinder 417 through an external device. The air inlet cylinder 417 is provided with a cooperating rod 418. The top of the cooperating rod 418 is provided with a sealing portion 429. The sealing portion 429 is in close contact with the inner wall of the air inlet cylinder 417, thereby playing a sealing role. When compressed gas enters the air inlet cylinder 417, it will cause the sealing portion 429 to be extruded, thereby pushing the cooperating rod 418 to move downward. When moving downward, the sliding block 48 connected to the cooperating rod 418 moves in the slide rail 47. The slide rail 47 is arranged inside the oil discharge filter chamber 43. The sliding block 48 and the slide rail 47 are provided with a limiting block to improve the stability of the movement. The sliding block 48 is connected to the cleaning plate 49. The cleaning plate 49 is driven by the sliding block 48 to move longitudinally and clean the outer surface of the oil discharge filter screen 46. It should be noted that the cooperating rod 418 needs to move longitudinally in the air inlet cylinder 417 and the oil discharge filter chamber 43, so a sealing arrangement is needed to prevent too much oil from entering the air inlet cylinder 417 and affecting the self-cleaning work;

[0132] The first inclined plate 410 is provided at the bottom of the cleaning plate 49, and the end of the first inclined plate 410 close to the oil discharge filter screen 46 is a blocking surface 424, the blocking surface 424 is at a 90-degree angle with the cleaning plate 49, and the part of the cleaning plate 49 in contact with the outer surface of the oil discharge filter screen 46 is a contact surface 428, the bottom of the contact surface 428 is an inclined guide surface 423, the contact surface 428 scrapes off the impurities on the oil discharge filter screen 46 when the cleaning plate 49 moves, and the impurities continuously accumulate and increase and then move along the guide surface 423, and finally accumulate on the blocking surface 424, the blocking surface 424 is used to limit the position of the scraped impurities, and part of the impurities that cannot accumulate on the blocking surface 424 will fall onto the second inclined plate 412 under the limitation of the blocking surface 424;

[0133] At the same time in the process, the air inlet cylinder 417 is always in an air inlet state, and the air inlet hole 420 is provided in the matching rod 418, the air inlet hole 420 is suitable for providing a small part of the compressed gas entering the air inlet cylinder 417 to pass through the sealing part 429 and enter the space in the matching rod 418, the gas enters the matching rod 418 and then enters the sliding block 48 and the cleaning plate 49, and finally is discharged through the horizontal gas outlet hole 421 on the contact surface 428 of the sliding block 48 and the downward inclined gas outlet hole 422 on the guide surface 423, the horizontal gas outlet hole 421 can discharge the gas and pass through the filter hole on the oil discharge filter screen 46, and plays a dredging role, and the gas outlet position of the downward inclined gas outlet hole 422 is opposite to the outer surface of the oil discharge filter screen 46, which can assist the cleaning plate 49 to stably scrape off all the impurities attached to the surface of the oil discharge filter screen 46;

[0134] The above steps are all self-cleaning work, including dredging and scraping off the surface impurities of the exhaust filter screen, but at this time the scraped impurities are still in the oil discharge filter chamber 43, and the cleaned impurities cannot be completely separated from the subsequent entering oil, resulting in that the impurities are more and more stacked, and the filter effect is not good;

[0135] Therefore when the cleaning plate 49 moves downward, the first inclined plate 410 connected to the bottom of the cleaning plate 49 moves synchronously, and when the cleaning plate 49 completely scrapes and cleans the surface of the oil discharge filter screen 46, the first inclined plate 410 extrudes the second inclined plate 412. The contact surface of the first inclined plate 410 and the second inclined plate 412 is inclined. The second inclined plate 412 originally extruded by the first inclined plate 410 from above should move downward, but it cannot move downward due to the fixed slide 414. However, the slide groove 430 is opened on the slide 414, the connecting seat 413 connected to the bottom of the second inclined plate 412 is slidably arranged in the slide groove 430, and the connecting seat 413 is connected with the extension rod two 415 and the spring two 416 in the slide groove 430. Therefore, when the second inclined plate 412 is extruded by the first inclined plate 410, the connecting seat 413 moves horizontally in the slide groove 430, so that the second inclined plate 412 and the connecting seat 413 move horizontally together. The first inclined plate 410 is a complete annular structure, and the second inclined plate 412 is in the form of several circumferentially distributed parts. Each second inclined plate 412 is connected with a separately corresponding connecting seat 413, and the slide groove 430 opened on the slide 414 corresponds to each connecting seat 413. When the second inclined plate 412 is not extruded by the first inclined plate 410, it is in an initial state. The end of the second inclined plate 412 close to the oil discharge filter screen 46 abuts against the oil discharge filter screen 46 to form a seal, the end of the corresponding connecting seat 413 away from the oil discharge filter screen 46 abuts against the inner wall of the groove 431 in the oil discharge filter screen 46 to form a seal, and the second inclined plate 412 and the corresponding connecting seat 413 are sealed on both sides. In the initial state, the whole is a complete disc shape, which blocks the channel between the oil discharge filter chamber 43 and the storage plate 44. When the oil discharge filter screen 46 needs to filter oil, the oil cannot penetrate into the storage plate 44. When in the self-cleaning mode, there is no oil in the oil discharge filter chamber 43, the cleaning plate 49 cleans the oil discharge filter screen 46, and when the first inclined plate 410 moves downward, the first inclined plate 410 extrudes all the second inclined plates 412, so that all the second inclined plates 412 and the corresponding connecting seats 413 move in the corresponding slide grooves 430, and realize a circular outward expansion form. At this time, the channel between the storage plate 44 and the oil discharge filter chamber 43 is opened, and the blocking surface 424 of the first inclined plate 410 and the guide surface 423 of the cleaning plate 49 are both located above the opened channel. At this time, the scraped impurities are affected by their own weight and fall into the storage plate 44, and the impurities that have not fallen are blown into the storage plate 44 by the blowing of the downward inclined air outlet 422. The impurities that have already fallen on the second inclined plate 412 during the movement and scraping of the cleaning plate 49 will fall into the storage plate 44 along the inclined part of the second inclined plate 412 during the extrusion of the first inclined plate 410 on the second inclined plate 412.The overall effect is that most of the impurities scraped off the oil drain filter 46 enter the receiving plate 44. In this way, when the cleaning plate 49 moves upward and resets, the connecting channel can be closed again to completely separate the impurities from the oil drain filter chamber 43, without causing pollution to the subsequent filtering of old oil. The reset of the cleaning plate 49 only requires the air intake cylinder 417 to stop the air intake and cooperate with the contraction spring 419 to reset the matching rod 418. When the cleaning process is completed, the operator can regularly open the second disassembly plate 411 to uniformly deal with the impurities accumulated in the receiving plate 44.

[0136] In addition, a plurality of auxiliary filters 425 of different precisions arranged at intervals can be set in the oil drain filter chamber 43. The auxiliary filters 425 are all located inside the oil drain filter 46 and are all plugged into the mounting seat 427 in the oil drain filter chamber 43. At the same time, the tops of all the auxiliary filters 425 and the oil drain filter 46 are connected to the lifting cover 426. The lifting cover 426 and the top of the oil drain filter chamber 43 are connected by bolts and sealed. When all the filters need to be cleaned after a long period of work, all the filters can be removed by pulling out the lifting cover 426, which is convenient to operate.

[0145] It should be noted that the outlet size of the new oil storage tank 52 is twice the size of the old oil storage tank 51, so that the old oil and the new oil can realize the proportional relationship of 1:2 when being simultaneously discharged into the premixing chamber 53, and the oil film generated under the mixing at the ratio is more stable;

[0146] The power impeller 56 driven to rotate by the rotating motor is arranged in the premixing chamber 53, the power impeller 56 is driven to rotate in the premixing chamber 53 by the rotating motor, and preferably rotates counterclockwise, since the outlet of the new oil storage tank 52 is arranged at the top of the premixing chamber 53, the power impeller 56 rotating counterclockwise can have the effect of stirring the old oil horizontally entering the premixing chamber 53 from below, but will not affect the flow of the new oil, and can provide the effect of mixing the old oil into the new oil;
