[0002] A hydraulic device is a machine that uses liquid as a working medium to transfer energy to achieve various processes. In addition to forging and forming, hydraulic devices can also be used for correction, pressing, packaging, pressing blocks and pressing plates. The basic principle is that the oil pump delivers the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and relief valves. Under the action of high-pressure oil, the cylinder moves.

[0003] At present, contaminants will remain in the hydraulic components of hydraulic devices during the processing and assembly process, and will fall into the hydraulic oil with the vibration of the machine, becoming hydraulic oil contaminants. In addition, when working in an environment with high air temperature, humid air will penetrate into the air filter and oil tank of the hydraulic device. As the temperature drops, it will condense into water and mix with the hydraulic oil, causing hydraulic oil emulsification. Therefore, when the hydraulic device is working, it is necessary to ensure the cleanliness of the hydraulic oil, reduce the wear of the hydraulic system caused by impurities, and reduce the influence of the presence of air and water in the oil on the rigidity and responsiveness of the hydraulic system.

[0015] The beneficial effects of the present invention are: 1. The present invention arranges a separation mechanism and zeolite particles filled in the separation mechanism, so that when the oil pumping mechanism is working, the separation mechanism is driven to rotate, so that the hydraulic oil contacts the zeolite particles in the separation mechanism through the separation mechanism, so that the zeolite particles absorb water in the hydraulic oil. After absorbing the water in the hydraulic oil, the zeolite particles release heat to heat the hydraulic oil, reduce the viscosity of the hydraulic oil, and prevent the viscosity of the hydraulic oil from being too high, which leads to an increase in flow resistance, thereby improving the working smoothness of the hydraulic device. The zeolite particles can also absorb the gas in the hydraulic oil, reduce the probability of rigidity reduction caused by the presence of gas, and ensure the timeliness of the hydraulic device during hydraulic operation, thereby providing good protection for the hydraulic device and extending the service life of the hydraulic device.

[0016] 2. The present invention uses an oil pumping mechanism and an oil filtering mechanism in coordination. The oil filtering mechanism can filter the hydraulic oil entering the oil tank through the return pipe. When the oil pumping mechanism is working, the oil filtering mechanism will operate, so that the oil filtering mechanism will transport the impurities remaining in the filtered hydraulic oil to the outside of the oil tank, thereby preventing the impurities from accumulating in the oil filtering mechanism and causing blockage of the oil filtering mechanism, thereby affecting the filtering efficiency of the hydraulic oil. The filtered hydraulic oil will enter the oil pumping mechanism and will enter the hydraulic oil in the oil tank only after being transported to the separation mechanism by the oil pumping mechanism, thereby preventing the hydraulic oil refluxed by the return pipe from directly entering the hydraulic oil in the oil tank, thereby preventing the impurities, water and gas in the refluxed hydraulic oil from polluting the hydraulic oil in the oil tank, thereby ensuring the cleanliness of the hydraulic oil.

[0017] 3. The present invention uses an oil pumping mechanism and a separation mechanism in coordination. When the oil pumping mechanism is working, it can directly input the hydraulic oil returned from the return pipe into the separation mechanism, so that the separation mechanism can separate the water and gas in the returned hydraulic oil. In addition, the oil pumping mechanism can also pump the hydraulic oil at the bottom of the oil tank into the separation mechanism, and further separate the water in the hydraulic oil, so as to avoid the presence of more water at the bottom of the hydraulic oil due to the different densities of water and hydraulic oil, which affects the performance of the hydraulic oil, thereby ensuring the stable operation of the hydraulic device, avoiding the presence of water that causes the lubricity of the hydraulic oil to decrease, resulting in increased structural wear of the hydraulic device, and providing good protection for the hydraulic device and extending the service life of the hydraulic device.

[0018] 4. The present invention uses a transmission mechanism and a shearing mechanism in coordination. When the separation mechanism revolves, the transmission shaft will be driven to revolve, thereby causing the transmission gear to revolve along the outer surface of the gear ring. At this time, since the gear ring is in a fixed state, the transmission gear will rotate during the revolution, thereby driving the transmission shaft to rotate during the revolution, so that the top oil spray pipe and the bottom oil spray pipe located in the separation frame rotate and spray hydraulic oil into the zeolite particles, so that the zeolite particles can better absorb water and adsorb water and gas in the hydraulic oil. At the same time, the transmission mechanism rotates during the revolution, which will cause the shearing mechanism to work, so that the shearing mechanism slides up and down and rotates along the inner surface of the slide frame, shearing the hydraulic oil in the oil tank, further reducing the viscosity of the hydraulic oil, and avoiding the increase in the wear of the hydraulic device caused by the excessive viscosity of the hydraulic oil, thereby ensuring the stable operation of the hydraulic device and extending the service life of the hydraulic device.

At the same time, when the rotating shaft 1202 rotates, the first bevel gear 1304 will be driven to rotate through the second bevel gear 1305, and then the screw shaft 1303 will be driven to rotate, so that the screw shaft 1303 can transport the residual impurities of the hydraulic oil filtered and returned by the oil filter 1302 to the storage box 1306, so as to avoid the accumulation of impurities in the oil filter 1302 and cause the oil filter 1302 to be blocked.

The separation mechanism 14 also includes an air pipe 1404 fixedly connected to the top of the fixed plate 1402, and the end of the air pipe 1404 away from the fixed plate 1402 is fixedly connected to a swivel 1405, and the top of the swivel 1405 is rotatably connected to a connecting ring 1406, and the top of the connecting ring 1406 is fixedly connected to an air guide pipe 1407, which passes through the guide plate 1309 and is sealed and fixedly connected to the guide plate 1309.

[0027] When in use, the rotation of the oil barrel 1203 will drive the separation frame 1401 and the fixed plate 1402 to revolve, so that the hydraulic oil will contact the zeolite particles in the separation frame 1401 through the separation frame 1401. At the same time, since the hydraulic oil in the oil barrel 1203 is located on the top of the piston plate 1209, it will enter the top injection pipe 1212 and then be sprayed out through the top injection hole 1213.

[0029] When in use, the revolution of the separation frame 1401 will drive the transmission shaft 1503 to revolve, and then drive the transmission gear 1502 to revolve. At this time, due to the setting of the gear ring 1501, the transmission gear 1502 will rotate while revolving, and then drive the transmission shaft 1503 to rotate while revolving. The rotation of the transmission shaft 1503 will drive the bottom oil injection pipe 1214 to rotate through the bottom worm gear 1504, so that the bottom oil injection hole 1215 can spray hydraulic oil to various parts of the zeolite particles filled in the separation frame 1401.

In the process of the lifting block 1601 sliding up and down, since the rotating gear 1603 is meshed with the tooth rod 1604, the up and down sliding of the lifting block 1601 will cause the rotating gear 1603 to rotate under the action of the tooth rod 1604, thereby driving the connecting shaft 1602 to rotate.

[0032] The specific working principle of the present invention is as follows: when in use, the driving motor 2 starts the hydraulic pump 3 to start working, sucks the hydraulic oil in the oil supply area of ​​the oil tank 1 through the oil suction pipe 10, and draws the hydraulic oil into the control valve 5 through the connecting pipe 4, and the control valve 5 is injected into the hydraulic telescopic rod 8 through the second oil pipe 9 and the first oil pipe 7, and the hydraulic oil in the hydraulic telescopic rod 8 will also enter the control valve 5 through the first oil pipe 7 and the second oil pipe 9, and the hydraulic oil returning to the control valve 5 will return to the transfer area of ​​the oil tank 1 through the return pipe 6, and enter the oil tank The hydraulic oil in the transfer area 1 will be diverted to the top of the oil filter 1302 under the action of the diverter block 1310, and after being filtered by the oil filter 1302, it falls on the guide plate 1309, thereby filtering the refluxed hydraulic oil and preventing the impurities contained in the refluxed hydraulic oil from being pumped into various components by the hydraulic pump 3 again, resulting in increased wear of the components. The various components of the hydraulic device are well protected, and the service life of the hydraulic device is extended. Finally, it flows from the guide plate 1309 to the hydraulic oil in the transfer area of ​​the oil tank 1; When the hydraulic device is working, the rotating motor 1201 is started to rotate the rotating shaft 1202, and the rotation of the rotating shaft 1202 will drive the oil barrel 1203 to rotate. At this time, the piston plate 1209 will slide up and down along the inner surface of the oil barrel 1203 under the limiting action of the part of the rotating shaft 1202 set in the form of a reciprocating screw and the limiting rod 1205. When the piston plate 1209 slides upward, the space of the oil barrel 1203 at the bottom of the piston plate 1209 will draw hydraulic oil. At this time, the guide The hydraulic oil on the top of the plate 1309 enters the connecting groove 1207 through the oil inlet hole 1206 (it should be noted that since the piston plate 1209 slides up and down intermittently, there will be accumulation of hydraulic oil on the top of the guide plate 1309, and the gas will not enter the oil barrel 1203), and then flows into the oil barrel 1203 through the oil discharge hole 1208. At the same time, the bottom pumping pipe 1210 will also pump the hydraulic oil at the bottom of the transfer area of ​​the oil tank 1 into the oil barrel 1203 at the bottom of the piston plate 1209. When the piston plate 1209 moves upward, the hydraulic oil in the oil barrel 1203 located at the top of the piston plate 1209 will enter the top oil injection pipe 1212 and then be sprayed out through the top oil injection hole 1213. When the piston plate 1209 slides downward, the space at the top of the piston plate 1209 of the oil barrel 1203 will extract the hydraulic oil at the bottom of the transfer area of ​​the oil tank 1 through the top oil extraction pipe 1211. At the same time, the space at the bottom of the piston plate 1209 of the oil barrel 1203 will be filled with the hydraulic oil. The hydraulic oil in the space will enter the bottom oil injection pipe 1214, and then be sprayed out through the bottom oil injection hole 1215. At the same time, when the rotating shaft 1202 rotates, the first bevel gear 1304 will be driven to rotate through the second bevel gear 1305, and then the screw shaft 1303 will be driven to rotate, so that the screw shaft 1303 can transport the impurities remaining in the hydraulic oil filtered and returned by the oil filter 1302 to the storage box 1306, so as to prevent the impurities from accumulating in the oil filter 1302 and causing the oil filter 1302 to be blocked; In this process, the rotation of the oil barrel 1203 will drive the separation frame 1401 and the fixed plate 1402 to revolve, so that the hydraulic oil will contact the zeolite particles in the separation frame 1401 through the separation frame 1401. At the same time, since the hydraulic oil in the oil barrel 1203 is located at the top of the piston plate 1209, it will enter the top oil injection pipe 1212 and then be sprayed out through the top oil injection hole 1213. The hydraulic oil sprayed out of the top oil injection hole 1213 will also contact the zeolite particles. The hydraulic oil in the oil barrel 1203 located in the bottom space of the piston plate 1209 will enter the bottom oil injection pipe 1214 and then be sprayed out through the bottom oil injection hole 1215. The hydraulic oil discharged will also contact with the zeolite particles, so that the zeolite particles absorb the water in the hydraulic oil, promote the uniformity of the hydraulic oil in the transfer area of ​​the oil tank 1, and further separate the water in the hydraulic oil to avoid the presence of more water at the bottom of the hydraulic oil due to the different densities of water and hydraulic oil, which affects the performance of the hydraulic oil, thereby ensuring the stable operation of the hydraulic device, avoiding the presence of water causing the lubricity of the hydraulic oil to decrease, resulting in increased structural wear of the hydraulic device, providing good protection for the hydraulic device and extending the service life of the hydraulic device. After absorbing the water in the hydraulic oil, the zeolite particles will release heat to heat the hydraulic oil and reduce the viscosity of the hydraulic oil. , preventing the viscosity of the hydraulic oil from being too high, which will lead to increased flow resistance, thereby improving the working smoothness of the hydraulic device, and the zeolite particles will also absorb the gas in the hydraulic oil, reducing the probability of reduced rigidity caused by the presence of gas, ensuring the timeliness of the hydraulic operation of the hydraulic device, thereby providing good protection for the hydraulic device and extending the service life of the hydraulic device. In this process, the revolution of the fixed plate 1402 will drive the gas pipe 1404 to revolve, thereby driving the swivel 1405 to rotate, and the gas adsorbed by the zeolite particles will flow upward along the outer surface of the zeolite particles. At the same time, since the zeolite particles release heat after absorbing water, they will heat the absorbed water. , accelerating the evaporation of water, and the additional water vapor will also flow upward along the outer surface of the zeolite particles. When the water vapor and gas flow upward and contact the fixed plate 1402, they will be transmitted to the rotating ring 1405 through the air pipe 1404, and then discharged to the injection pipe 1408 through the air guide pipe 1407, and finally sprayed to the bottom of the oil filter 1302 through the injection head 1409, so as to clear the impurities blocked in the holes of the oil filter 1302, thereby avoiding the blockage of the oil filter 1302 and affecting the filtering efficiency of the refluxed hydraulic oil, and the gas clearing the holes of the oil filter 1302 will enter the impurity storage box 1306, and finally discharged to the external environment through the exhaust pipe 1308; At the same time, the revolution of the separation frame 1401 will drive the transmission shaft 1503 to revolve, and then drive the transmission gear 1502 to revolve. At this time, due to the setting of the gear ring 1501, the transmission gear 1502 will rotate while revolving, and then drive the transmission shaft 1503 to rotate while revolving. The rotation of the transmission shaft 1503 will drive the bottom oil injection pipe 1214 to rotate through the bottom worm gear 1504, so that the bottom oil injection hole 1215 can spray the hydraulic oil to various parts of the zeolite particles filled in the separation frame 1401. At the same time, the rotation of the transmission shaft 1503 will also drive the top oil injection pipe 1212 to rotate through the top worm gear 1505, so that the top oil injection hole 1213 can spray the hydraulic oil to various parts of the zeolite particles filled in the separation frame 1401, so that the zeolite particles can fully absorb the water and gas contained in the hydraulic oil, thereby ensuring the quality and efficiency of the hydraulic oil purification. When the transmission shaft 1503 rotates, the transmission shaft 1503 will drive the lifting block 1601 to slide up and down along the inner surface of the slide frame 1403 through the part set in the form of a reciprocating screw. During the up and down sliding of the lifting block 1601, since the rotating gear 1603 is meshed with the tooth rod 1604, the up and down sliding of the lifting block 1601 will cause the rotating gear 1603 to rotate under the action of the tooth rod 1604, thereby driving the connecting shaft 1602 to rotate. The rotation of the connecting shaft 1602 will drive the shear knife 1605 to shear the hydraulic oil, further reducing the viscosity of the hydraulic oil, avoiding the increase of wear of the hydraulic device caused by excessive viscosity of the hydraulic oil, thereby ensuring the stable operation of the hydraulic device and extending the service life of the hydraulic device. When the hydraulic device stops working, the drive motor 2, the hydraulic pump 3, the control valve 5 and the rotating motor 1201 are turned off. When it is necessary to clean the impurities entering the debris storage box 1306, the sealing door 1307 is opened to clean the impurities in the debris storage box 1306. After cleaning, the sealing door 1307 can be reinstalled on the debris storage box 1306.
