Description

Technical Field

[0001] This utility model relates to the field of medical equipment maintenance technology, specifically to a tube oil change device. Background Technology

[0002] The CT tube is the core component of CT equipment. The cooling oil filled inside it must meet both insulation and heat dissipation requirements. In existing technology, old oil is usually discharged and new oil is injected by driving an electric pump.

[0003] Chinese utility model patent application CN222146129U discloses a vacuum oil changing device for a CT tube: It includes a vacuum oil changing tank, a mounting frame, and a purification tank. The mounting frame is installed on the bottom wall of the vacuum oil changing tank, and the CT tube body is mounted on the top of the mounting frame. The purification tank is installed on the bottom wall of the vacuum oil changing tank, and the salt storage tank is installed on the top of the vacuum oil changing tank. The electric push rod, motor, oil pump, and other electrical components are all located inside the oil changing tank. The oil pump extracts oil from the CT tube body. When the extracted oil meets the requirements for secondary use, salt from the salt storage tank falls into the purification tank through a dispensing pipe. An electric heating plate heats the purification tank, and a stirring motor drives a stirring frame to rotate, thoroughly and evenly mixing the oil and salt. The oil pump extracts the purified oil and re-transports it into the CT tube body. This secondary treatment and recycling of the oil discharged from the CT tube body avoids oil waste.

[0004] However, existing technologies still have shortcomings:

[0005] When the above device is working, the vacuum pump needs to be started to evacuate the gas in the vacuum oil exchange tank to make the vacuum oil exchange tank approach a vacuum environment. However, the oil exchange tank is equipped with electric push rods, motors, oil pumps and other electric components. After the vacuum environment is established, the above electric components need to be started. The vacuum environment is not conducive to the flow of gas, so it is not conducive to the heat dissipation of the above components. At the same time, it is necessary to select components that are suitable for vacuum conditions, which increases the manufacturing and maintenance costs of the device. Utility Model Content

To this end, this invention proposes a tube oil changing device to address the problem in the prior art where multiple electric components are installed inside the vacuum oil changing tank, affecting the heat dissipation of the electric components and increasing the overall manufacturing and maintenance costs of the device.

[0007] To achieve the above objectives, this utility model proposes a pneumatic tube oil changing device, including an oil changing tank. The oil changing tank contains a clamping assembly for holding the pneumatic tube body. A vacuum pump is fixedly installed on the side of the oil changing tank.

When the oil quality detection probe detects that the oil in the purification tank 17 meets the requirements for reuse, the solenoid valve is activated, and salt from the storage tank 6 falls into the purification tank 17 through the salt delivery pipe 19. The second motor 8 is then activated, driving the stirring rod to mix the oil and salt in the purification tank 17 until the air bubbles are reduced and disappear. An oil pump 12 is fixedly installed on the oil exchange tank 1. The oil pump 12 delivers... The inlet is connected to the purification tank 17 through a pipe, and the output port of the oil pump 12 is connected to the filter box 13 through a pipe.

Two pairs of support legs 3 are fixedly installed below the oil change tank 1. A door 2 is fixedly installed on the side of the oil change tank 1.

[0029] Working principle:

[0030] First, the tube body 16 is placed between a pair of clamping plates 24. Then, the first motor 10 is started, driving the bidirectional screw 25 to rotate. The bidirectional screw 25 drives a pair of threaded sleeves 26 to move towards each other, thereby causing the pair of clamping plates 24 to move towards each other to achieve stable clamping of the tube body 16. The box door 2 is closed. The vacuum pump 9 is started to evacuate the oil tank 1. The oil pump 7 is started to extract the oil from the tube body 16 and pump it into the purification box 17. When the oil quality detection probe detects that the oil in the purification box 17 meets the requirements for reuse, the oil is ready for use. Start the solenoid valve, and the salt in the salt storage tank 6 falls into the purification tank 17 through the salt delivery pipe 19. Start the second motor 8, which drives the stirring rod to stir the oil and salt in the purification tank 17 until the bubbles are reduced and disappear. Then start the oil delivery pump 12 to pump the oil in the purification tank 17 into the filter box 13 for filtration. When the oil quality detection probe detects that the oil in the purification tank 17 does not meet the requirements for secondary use, start the oil pump 11 to pump the oil in the oil storage tank 5 into the filter box 13. After being filtered by the filter box 13, the oil flows into the X-ray tube body 16.
