Description

Technical Field

[0001] The invention relates to the technical field of hydraulic stations, and in particular to a high-precision energy-saving hydraulic station for metallurgy. Background Art

[0002] The hydraulic station is an independent hydraulic device, which supplies oil according to the requirements of the drive device and controls the direction, pressure and flow of the oil flow. It is suitable for various hydraulic machinery in which the main engine and the hydraulic device are separable. The oil pump is driven by the motor to rotate, and the pump sucks oil from the oil tank and pumps oil to convert mechanical energy into the pressure energy of the hydraulic oil. The existing hydraulic stations used for metallurgical operations still have certain disadvantages when in use. First of all, the existing hydraulic stations used for metallurgical operations are affected by the working environment, resulting in a slow cooling of the oil temperature in the oil tank, which will cause certain damage to the hydraulic station as a whole after a long time. The existing heat dissipation structure has poor heat dissipation effect. Due to the poor fluidity of the oil, the traditional passive heat dissipation structure with interlaced heat pipes is difficult to meet the high-load working requirements. Summary of the invention

[0003] In order to solve the problem of poor heat dissipation effect of the existing heat dissipation structure in the prior art, the present invention provides a high-precision energy-saving hydraulic station for metallurgy.

[0004] The technical solution of the present invention is:

[0005] The present invention provides a high-precision energy-saving hydraulic station for metallurgy, comprising a main body of the hydraulic station, an oil tank is arranged inside the main body, a transverse sealed rotating shaft runs through the middle of the oil tank, a driven wheel is installed at one end of the rotating shaft located outside the oil tank, a driving motor is installed inside the main body, a driving wheel is installed on the output shaft of the driving motor, the driving wheel and the driven wheel are connected through a transmission belt, two blind holes are arranged at the other end of the rotating shaft located outside the oil tank, and the end of the rotating shaft with the blind holes is connected to a circulating heat dissipation device through a rotating connection structure;

[0006] A heat dissipation structure in which a circular distribution array is connected to two blind holes on the side of a rotating shaft located in an oil tank. Each group of heat dissipation structures includes several parallel heat dissipation plates, which are connected end to end by springs. Two circulation cavities are provided inside the heat dissipation plates. Two adjacent heat dissipation plates are connected one-to-one in the heat dissipation cavities by connecting pipes. The end of the heat dissipation plate at one end of the several heat dissipation plates connected end to end is fixedly connected to the side of the rotating shaft by a spring, and the two circulation cavities are respectively connected to the two blind holes by connecting pipes. The two circulation cavities are connected in the end of the heat dissipation plate at the other end of the several heat dissipation plates connected end to end, which is away from the spring.

[0007] Furthermore, the end of the spring is fixedly connected to a position of the plate surface of the corresponding heat sink near a corner.

[0008] Furthermore, the proximal ends of the springs disposed on two adjacent heat dissipation plates are connected in a one-to-one manner to the heat dissipation cavity through a connecting pipe.

[0009] Furthermore, the rotating connection structure includes a blind hole located at the other end side of the rotating shaft, and a staggered first through hole is opened. The other end of the rotating shaft is rotatably covered with a sealing sleeve, and annular grooves are opened on the inner wall of the sealing sleeve corresponding to the position of the first through hole. Sealing rings are arranged between the rotating shaft and both sides of the annular groove inside the sealing sleeve, and a second through hole communicating with the two annular grooves is opened on the outer side of the sealing sleeve. The two second through holes are respectively connected to the inlet and outlet of the circulating heat dissipation device.

[0010] Furthermore, the circulating heat dissipation device includes a water tank arranged in the body, the two second through holes are connected to one end of the circulating water pipe, and the other end of the circulating water pipe is connected to the inlet and outlet of the circulating pump in the water tank.

[0011] The beneficial effects achieved by the present invention are:

[0012] When the present invention is used, the circulation pump works, and the water in the water tank forms a circulation through the circulating water pipe, the annular groove, the first through hole, the blind hole, the connecting pipe, and the circulation cavity. The rotating shaft is driven to rotate by the driving motor. At this time, due to the action of centrifugal force, the spring is arranged at one of the corners of the heat sink, and the originally parallel heat sinks are relatively tilted. The heat sink rotating with the rotating shaft circulates and stirs the oil in the oil tank. The water circulating in the heat sink absorbs the heat of the oil and dissipates the heat. When the rotation speed is different, the inclination angle of the heat sink is different, so that the oil is stirred with different strengths and the heat dissipation efficiency is different, which can be adjusted according to the temperature of the oil.

[0021] The heat dissipation structure is a circular distribution array on the side of the rotating shaft 3 located in the oil tank and is cyclically connected to two blind holes. Each group of heat dissipation structures includes several parallel heat dissipation plates 12, and the several heat dissipation plates 12 are connected end to end by springs 13. The end of the spring 13 is fixedly connected to the plate surface of the corresponding heat dissipation plate near a corner. Two circulation cavities 14 are provided inside the heat dissipation plate. The proximal ends of the springs provided on two adjacent heat dissipation plates are connected one-to-one with the heat dissipation cavities through a connecting pipe 16. The end of the heat dissipation plate at one end of the several heat dissipation plates connected end to end is fixedly connected to the side of the rotating shaft through the spring 13, and the two circulation cavities are respectively connected to the two blind holes 15 through a connecting pipe. The two circulation cavities are connected in the end of the heat dissipation plate at the other end of the several heat dissipation plates connected end to end, which is far away from the spring.

[0022] The rotating connection structure includes a blind hole 15 and a staggered first through hole 5 on the side of the other end of the rotating shaft. A sealing sleeve 6 is rotatably mounted on the other end of the rotating shaft. An annular groove 7 is formed on the inner wall of the sealing sleeve 6 at a position corresponding to the first through hole 5. A sealing ring 8 is arranged between the rotating shaft and both sides of the annular groove inside the sealing sleeve.

The driving motor drives the shaft to rotate. At this time, due to the centrifugal force, the spring is set at one of the corners of the heat sink, and the originally parallel heat sinks are relatively tilted. The heat sink rotating with the shaft circulates and stirs the oil in the oil tank. The circulating water in the heat sink absorbs the heat of the oil and dissipates the heat. When the speed is different, the tilt angle of the heat sink is different, so that the oil is stirred with different strengths and the heat dissipation efficiency is different, which can be adjusted according to the temperature of the oil.
