Description

Technical Field

[0002] As an important force transmission medium in the hydraulic system, the temperature state of hydraulic oil directly affects the operating efficiency and stability of the system. When the temperature of hydraulic oil is too high, it will cause a series of problems. First, high temperature will cause the viscosity of hydraulic oil to decrease, which will not only increase the leakage inside the system, but also reduce the accuracy and efficiency of the system movement. Therefore, the oil in the hydraulic oil pipe needs to be cooled.

The n-shaped frame 122 is provided with a filter assembly. When the filter assembly is in operation, the filter assembly can filter impurities in the air; the filter assembly includes a switch valve II 128, a discharge pipe 129, a partition 1210, an electric filter cartridge 1211, a two-way air pump 1212 and a brush plate 1213. The upper part of the n-shaped frame 122 is symmetrically connected to the discharge pipe 129, and the discharge pipe 129 can discharge impurities. The upper part of the discharge pipe 129 is rotatably connected to the switch valve II 128. The right ends of the switch valve II 128 on both sides are connected to the right side of the switch valve I 126 through a synchronous belt assembly.

The electric filter cartridge 1211 can filter impurities in the air, and a brush plate 1213 is symmetrically fixed on the top of the upper partition 1210. The brush plate 1213 is in contact with the inner wall of the electric filter cartridge 1211. When the electric filter cartridge 1211 rotates, the brush plate 1213 can remove impurities attached to the inner wall of the electric filter cartridge 1211. A two-way air pump 1212 is installed between the lower parts of the front and rear sides of the n-type frame 122.

[0034] Initially, the cooling frame 6, the cooling pipe 7 and the liquid guide shell 8 are all filled with an appropriate amount of coolant, the front switch valve II128 is in a closed state, the rear switch valve II128 is in an open state, and the switch valve I126 is connected to the front side of the n-type frame 122. First, the oil inlet pipe 2 and the oil outlet pipe 3 are both externally connected to the hydraulic oil pipe, and then the electric dispersion wheel 41 is started to reverse. When the oil is discharged into the oil inlet pipe 2, the oil is discharged into the round shell 4 and contacts the electric dispersion wheel 41. The electric dispersion wheel 41 reverses and pushes the oil into the four diversion pipes 5, so that the oil is divided into four parts and flows. The oil in the diversion pipe 5 contacts the outer wall of the cooling pipe 7. At this time, the circulation pump 9 is started, and the circulation pump 9 discharges the coolant in the upper liquid guide shell 8 into the cooling pipe 7. The coolant flows in the cooling pipe 7, and the cooling pipe 7 cools the oil in the shunt pipe 5 from the inside, and the coolant absorbs the heat in the oil and takes it away. At the same time, part of the coolant in the cooling pipe 7 is discharged into the cooling frame 6 through the upper branch pipe 10. The coolant in the cooling frame 6 flows on the outer wall of the shunt pipe 5, and the coolant in the cooling frame 6 cools the oil from the outside. In this way, the oil can be cooled from both the inside and the outside at the same time, thereby improving the effect of cooling the oil. At the same time, the oil in the shunt pipe 5 is also in contact with the guide plate 11, and the guide plate 11 blocks and guides the oil, so that the oil stays in contact with the cooling pipe 7 and is cooled. The guide plate 11 allows the oil to be cooled for a longer time, thereby further improving the cooling effect. The cooled oil continues to flow to the right, and the cooled oil The oil is discharged through the oil outlet pipe 3, and the coolant that absorbs heat in the cooling pipe 7 is discharged into the lower liquid guide shell 8. The coolant that absorbs heat in the cooling frame 6 is discharged into the lower liquid guide shell 8 through the lower branch pipe 10. The coolant in the lower liquid guide shell 8 continues to be pumped away by the circulation pump 9 for recycling. This is repeated to continuously cool the flowing oil. At the same time, the front control valve 124 is started to open, and the air supply pump 123 is started. The air supply pump 123 discharges air into the n-type frame 122 through the switch valve I 126. The air in the n-type frame 122 is discharged into the front electric filter cartridge 1211. The front electric filter cartridge 1211 first filters impurities in the air, and the air after filtering impurities passes through the front electric filter cartridge 1211 and is discharged into the front control valve 12 4, the front control valve 124 discharges air into the annular nozzle 12 through the three-way pipe 125, and the annular nozzle 12 sprays air into the cylinder 1, and the air contacts the cooling pipe 7 and the cooling frame 6, and the air cools the cooling pipe 7 and the cooling frame 6 to prevent the cooling pipe 7 and the cooling frame 6 from having high temperature due to the heat in the coolant, thereby ensuring the normal use effect of the cooling pipe 7 and the cooling frame 6, and the air after the cooling of the cooling frame 6 and the cooling frame 6 continues to move to the left and flows through the filter 121 to be discharged, and this is repeated, and the cooling frame 6 and the cooling frame 6 can be continuously cooled. When a large amount of impurities are filtered on the front electric filter cartridge 1211, the front control valve 124 is closed, and the drive motor 127 is started to drive the switch valve I 126 to rotate forward 90 degrees.The switch valve Ⅰ126 rotates forward 90 degrees to stop communicating with the front side of the n-type frame 122 and communicates with the rear side of the n-type frame 122. At the same time, the switch valve Ⅰ126 rotates forward 90 degrees and drives the switch valves Ⅱ128 on the front and rear sides to rotate forward 90 degrees through the synchronous belt assembly. The front switch valve Ⅱ128 is opened and the rear switch valve Ⅱ128 is closed. The air supply pump 123 discharges air into the rear side of the n-type frame 122 through the switch valve Ⅰ126. The rear electric filter cartridge 1211 filters impurities in the air. The rear control valve 124 is started. The air is discharged into the three-way pipe 125 through the rear control valve 124, and is sprayed out through the annular nozzle 12 to cool the cooling pipe 7 and the cooling frame 6. At this time, the front electric filter cartridge 1211 is started to rotate, and the brush plate 1213 removes impurities attached to the inner wall of the front electric filter cartridge 1211. The two-way blowing pump 121 is started. 2. The air is discharged into the front side of the n-type frame 122, and the air is discharged into the front electric filter cartridge 1211. The air blows the removed impurities upwards, and the impurities blown upwards are discharged into the front discharge pipe 129 through the front switch valve II 128. The front discharge pipe 129 discharges and collects the impurities. When the impurities on the inner wall of the front electric filter cartridge 1211 are cleaned, the front electric filter cartridge 1211 is closed, and then the two-way air pump 1212 is closed. In this way, the impurities in the electric filter cartridge 1211 can be cleared without stopping the air cooling. When it is necessary to clear the impurities in the rear electric filter cartridge 1211, the impurities in the electric filter cartridge 1211 can be cleared and collected according to the above operation. When no oil is discharged into the oil inlet pipe 2, the electric dispersion wheel 41, the circulation pump 9 and the air supply pump 123 can be closed, and the coolant in the cooling pipe 7 and the cooling frame 6 stops flowing.

A conveying assembly is provided on the shell 131. When the conveying assembly is in operation, the conveying assembly can drive the oil to move to the left for transportation; the conveying assembly includes a screw conveying shaft 134 and a stepper motor 135. The screw conveying shaft 134 is rotatably connected between the left and right sides of the shell 131, and the stepper motor 135 is installed on the right side outside the shell 131, and the output shaft end of the stepper motor 135 is fixedly connected to the right end of the screw conveying shaft 134.

[0036] When the oil is discharged into the four shunt pipes 5, the temperature sensor 13 monitors the temperature in the four shunt pipes 5. When the temperature of one of the shunt pipes 5 exceeds the set maximum value, the corresponding temperature sensor 13 controls the electric control liquid pumping pipe 133 on the shunt pipe 5 with high internal temperature and the electric control liquid discharge pipe 132 on the shunt pipe 5 with low internal temperature through the control module to start. The electric control liquid pumping pipe 133 pumps part of the oil in the shunt pipe 5 with high internal temperature into the housing 131. The oil in the housing 131 is connected to the screw conveying shaft 131. 34 contact, start the stepper motor 135 to drive the screw conveying shaft 134 to rotate, the screw conveying shaft 134 rotates to drive the oil in the housing 131 to move to the left, the oil moves to the left through the electric control drain pipe 132 and is discharged into the shunt pipe 5 with a lower internal temperature. When the temperature in the shunt pipe 5 drops to the standard value, the temperature sensor 13 controls the corresponding electric control drain pipe 132 and the electric control pumping pipe 133 to close through the control module, and turns off the stepper motor 135, and the stepper motor 135 stops driving the screw conveying shaft 134 to rotate. In this way, it can prevent the excessive oil in some of the shunt pipes 5 from affecting the cooling effect, thereby ensuring that the four shunt pipes 5 can be fully utilized so that the oil is cooled.

A plurality of heat dissipation copper sheets 14 are evenly spaced and fixedly connected between the three groups of cooling pipes 7.
