[0038] like Figure 1 As shown, the utility model discloses a liquid recovery device, including: a recovery liquid tank 1, a lubricating liquid pipeline 2, a lubricating liquid recovery pipeline 3, a drainage pipeline 4, a liquid pump 5, a filter 6 and a flushing pipe 7; the lubricating liquid pipeline 2 is connected to the system pipeline, and a liquid replenishing pipeline is connected between the system pipeline and the recovery liquid tank 1; the lubricating liquid recovery pipeline 3 is connected to the recovery liquid tank 1 through a return pipe; the drainage pipeline 4 is connected to one side of the recovery liquid tank 1, and the drainage pipeline 4 is connected to the lubricating liquid pipeline 2; the liquid pump 5 is connected to the drainage pipeline 4; the drainage pipeline 4 is connected to the drainage pipeline 4; the flushing pipe 7 is connected to the drainage pipeline 4, and one end of the flushing pipe 7 is connected to a spray ball.

[0039] In the embodiment of the present utility model, as Figure 1 As shown, it also includes: a first butterfly valve 8, a second butterfly valve 9 and a one-way valve 10; the first butterfly valve 8 is connected between the recovery liquid tank 1 and the liquid pump 5; the second butterfly valve 9 is connected to the flushing pipe 7; the one-way valve 10 is connected between the liquid pump 5 and the filter 6.

[0040] In the embodiment of the present utility model, as Figure 1 As shown, it also includes: a first pressure transmitter 11 and a second pressure transmitter 12; the first pressure transmitter 11 is connected to one side of the recovery liquid tank 1; the second pressure transmitter 12 is connected to the drain pipe 4, and the second pressure transmitter 12 is connected between the filter 6 and the lubricating liquid pipe 2.

[0041] In the embodiment of the present utility model, as Figure 1 As shown, it also includes: a first solenoid valve 13, a second solenoid valve 14 and a third solenoid valve 15; the first solenoid valve 13 is connected to the drainage pipe 4; the second solenoid valve 14 is connected to the fluid replenishment pipe; the third solenoid valve 15 is connected to the system pipe.

[0042] In the embodiment of the present utility model, as Figure 1 As shown, it also includes: an overflow port 16; the overflow port 16 is opened at the top of the recovery liquid tank 1.

[0043] In the embodiment of the present utility model, as Figure 1 As shown, it also includes: a liquid level switch 17; the liquid level switch 17 is connected to one side of the recovery liquid tank 1.

[0044] Implementation process: The lubricating fluid enters the recovery system through natural reflux, and first passes through three-stage filtration into the recovery liquid tank 1. The first layer is a high liquid level alarm (when the filter cotton is blocked, the water level becomes high, which will trigger the liquid level alarm switch), the second layer is a stainless steel filter (to remove dust and silt, etc.), and the third layer is a filter cotton (to filter large particles of impurities and solid waste, suspended matter, bacteria, dust, etc.). After reaching the detection height, it is re-supplied into the system through the liquid pump 5. The solenoid valve is opened to allow the liquid to pass through the filter and be supplied to the water point. It is also equipped with automatic sewage discharge and replacement functions. If the liquid level is insufficient, it will be replenished by the original system.

[0045] The electrical box connects the liquid level switch 17, the first pressure transmitter 11, the second pressure transmitter 12, the liquid pump 5, the first solenoid valve 1, the second solenoid valve 2, and the third solenoid valve 3. The liquid level switch 17 is used to indicate when the liquid level in the first filter is too high; the first pressure transmitter 11 is used to detect the liquid level in the water tank; the second pressure transmitter 12 is used to check the pipeline pressure; the liquid pump 5 is used to transport and pressurize the liquid; and the solenoid valve is used to control the direction of the liquid flow.

[0046] First, replenish liquid into the recovery liquid tank 1. After replenishing, the lubricating oil system circulates and recycles. When the liquid is replenished to the liquid level switch 17, the second solenoid valve 14 on the replenishing pipeline is closed, and the first butterfly valve 8, the second solenoid valve 14 and the third solenoid valve 15 are opened. At this time, the lubricating liquid in the recovery liquid tank 1 enters the lubricating liquid pipeline 2 and the system pipeline through the drain pipe. If the inside of the recovery liquid tank 1 needs to be flushed, the second butterfly valve 9 on the flushing pipe 7 needs to be opened for flushing. The overflow port 16 can discharge excess lubricating liquid. The first pressure transmitter 11 is used to monitor the liquid level, the second pressure transmitter 12 is used to monitor the pressure in the pipeline, and the filter 6 is used to filter impurities in the liquid.
