[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0018] Figure 1 This is a schematic diagram of the structure of an oil-changing device suitable for a vacuum pump used in precious metal hydrometallurgy, according to one embodiment. The device comprises an oil-changing tank 1, a first oil outlet pipe 2, an elbow 3, a second oil outlet pipe 4, a rubber hose 5, a control valve 6, and a heating device 7. The oil-changing tank 1 is rectangular in shape, with the heating device 7 disposed outside the tank 1. An inclined bottom plate is disposed at the bottom of the tank 1, forming an angle with the horizontal plane. An oil outlet is defined on one sidewall of the tank 1, with the lowest point of the bottom plate adjacent to and flush with the lower edge of the outlet. One end of the first oil outlet pipe 2 is connected to the outlet, and the other end is connected to one end of the elbow 3. The other end of the elbow 3 is connected to one end of the second oil outlet pipe 4, forming a 90-degree angle with the second oil outlet pipe 4. The other end of the second oil outlet pipe 4 is connected to the rubber hose 5, which is provided with the control valve 6.
[0019] A heating device 7 is provided on the outside of the oil change tank 1 to maintain the fluidity of the oil in cold environments, ensuring a smooth oil change process and preventing excess oil residue. In one embodiment, the heating device can be provided on the bottom or around the side walls of the oil change tank 1, and the energy source for the heating device can be provided by a battery or by connecting to a power source.
[0020] In one embodiment, the oil exchange tank 1, the first oil outlet pipe 2, the elbow 3, and the second oil outlet pipe 4 are formed into a whole by welding.
[0021] In one embodiment, the oil exchange tank 1 is a rectangular parallelepiped tank body with a length of 1100 mm, a width of 400 mm, a height of 100 mm, and a wall thickness of 5 mm.
[0022] In one embodiment, the diameter of the oil outlet of the oil exchange tank 1 is 40 mm, and the diameters of the first oil outlet pipe 2 and the second oil outlet pipe 4 are also 40 mm.
[0023] The inclined bottom plate provided at the bottom of the oil changing tank 1 facilitates the smooth drainage of the vacuum pump oil and prevents a large amount of vacuum pump oil from remaining in the oil changing tank 1. In one embodiment, the angle between the bottom plate and the horizontal plane is between 10-30 degrees, for example, 20 degrees.
[0024] The 90-degree angle between the first oil outlet pipe 2 and the second oil outlet pipe 4 is conducive to connection with the elbow, and can ensure smooth oil flow from the oil outlet pipe without too much vacuum pump oil remaining in the pipeline.
[0025] In one embodiment, the oil exchange tank 1 , the first oil outlet pipe 2 , and the second oil outlet pipe 4 are all made of PVC.
[0026] In one embodiment, a filter is provided at the oil outlet of the oil exchange tank 1 to filter out impurities and solid particles in the waste oil before it is discharged.
[0027] During operation, place the oil change tank below the vacuum pump's oil outlet, and connect the rubber hose outlet to the oil storage container. When changing the vacuum pump's oil, the vacuum pump oil flows from the oil outlet into the oil change tank. The tilted placement of the bottom plate helps the vacuum pump oil gather at the oil outlet, and then is introduced into the oil storage container through the oil outlet pipe and rubber hose to complete the oil draining work.
