Further, when the liquid ring pump 1 is started, the working fluid in the first tank compartment 22 is pressed into the second tank compartment 23 through the communication port 24.
The gas discharge port 11 of the liquid ring pump is connected to the gas-liquid separation tank 2, the system gas discharge port is provided at the upper part of the gas-liquid separation tank 2, the gas from the gas discharge port 11 of the liquid ring pump is discharged from the tank body gas discharge port 221, and is collected and treated by the gas collecting device, and the liquid from the gas discharge port 11 of the liquid ring pump is left in the gas-liquid separation tank 2. An inverted L-shaped liquid level separation plate 21 is welded in the gas-liquid separation tank 2, the liquid level separation plate 21 and the pipe wall of the gas-liquid separation tank 2 are fully welded, and a circulation opening 24 with the diameter of about 2 centimeters is formed in the bottom of the liquid level separation plate 21 and the bottom of the gas-liquid separation tank 2 to ensure that working liquid can circulate. Liquid level division board 21 can be cut apart into two independent cavitys with gas-liquid separation jar 2 inner space when working solution is higher than liquid level division board 21 lower part in gas-liquid separation jar 2, install overflow pipe 28 on gas-liquid separation jar 2, overflow pipe 28's one end need submerge in the below working solution level the other end and set up in gas-liquid separation jar 2 outside, the main function is isolated gas-liquid separation jar 2 air outflow and can follow overflow pipe 28 when the liquid level in gas-liquid separation jar 2 is higher than overflow pipe 28 upper end and discharge, prevent that the too high liquid ring pump 1 that arouses of working solution level from overloading in gas-liquid separation jar 2.

Further, the height of the circulation port 24 from the bottom plate of the gas-liquid separation tank 2 is 2 to 3cm, preferably 2 cm.
It should be noted that the operating fluid level in the first tank compartment 22 is higher than the level of the communication port 24.
As shown in FIG. 3, as a preferred embodiment, the portion of the overflow pipe 28 located within the second tank compartment 23 is an inverted L-shape that includes a horizontally disposed horizontal duct 281 and a vertically disposed vertical duct 282, wherein an overflow inlet 283 in the lower portion of the vertical duct 282 is located below the operating liquid level within the second tank compartment 22.
In the initial state, the liquid level in the gas-liquid separation tank 2 (the liquid level in the first tank compartment 22 is consistent with that in the second tank compartment 23) is positioned at the central line of the driving shaft of the liquid ring pump 1 (namely, at the middle position from the lower end of the liquid level division plate 21 to the upper end of the overflow pipe 28). When the liquid ring pump 1 is started, the gas passing through the gas outlet 11 of the liquid ring pump generates a certain positive pressure to the first tank compartment 22 in the gas-liquid separation tank 2, so that the liquid level in the first tank compartment 22 drops by a certain height, and the liquid level drop caused by the pressure must ensure that the liquid level is always higher than the lower end of the liquid level division plate, otherwise the gas intercommunication working liquid in the first tank compartment 22 and the second tank compartment 23 is left from the overflow pipe 28, so that the liquid level in the second tank compartment 23 drops to the height consistent with the liquid level in the first tank compartment 22, and the overflow pipe 28 loses the liquid sealing effect. Since the vertical portion of level divider 21 divides the liquid in the tank into a portion that is within first tank compartment 22 and a portion that is much smaller than the area within second tank compartment 23. For this reason, when the height of the liquid level 1 changes, the influence on the liquid level 2 is small, so that the bottom of the overflow pipe is always below the liquid level 2, namely, the liquid seal state is always realized, and the gas in the tank cannot flow out of the overflow pipe.
If no liquid level partition plate is arranged, when the liquid ring pump is started, the pressure in the pipe can press the working liquid out of the tank from the bottom of the overflow pipe. If the bottom of the overflow pipe is still below the liquid level, the liquid level in the tank is too low to meet the working requirement of the liquid ring pump, and the liquid ring pump is damaged; if the bottom of the overflow pipe is assumed to be level with the liquid level, gas in the tank flows out of the tank from the bottom of the overflow pipe due to consumption of working liquid and fluctuation of the liquid level during working, so that potential hazard of liquid seal cannot be realized, and the production environment is unsafe.
As shown in fig. 3, as a preferred embodiment, the bottom of the second tank compartment 23 is provided with an evacuation line 29, the evacuation line 29 is provided with an evacuation valve 291 which is controlled by a controller to open and close, and a portion of the evacuation line 29 located at the rear side of the evacuation valve 291 is communicated with the overflow pipe 28, so that the working fluid can be completely evacuated when impurities need to be discharged or maintenance needs to be performed.
As shown in fig. 3, as a preferred embodiment, a guiding inclined plate 4 is arranged at the communication port 24, and the guiding inclined plate 4 is obliquely and downwards directed to the second tank compartment 23.
It should be noted that when the liquid ring pump 1 is used to pump dust, the inclined guide plate 4 can guide the dust in the first tank compartment 22 into the second tank compartment 23, so as to prevent the dust from concentrating at the bottom of the first tank compartment 22.
The working process is as follows:
when the liquid ring pump 1 is started, the gas passing through the gas outlet 11 of the liquid ring pump generates a certain positive pressure to the first tank compartment 22 in the gas-liquid separation tank 2, so that the liquid level in the first tank compartment 22 drops by a certain height, and the liquid level drop caused by the pressure must ensure that the liquid level is always higher than the lower end of the liquid level division plate, otherwise the gas intercommunication working liquid in the first tank compartment 22 and the second tank compartment 23 is left from the overflow pipe 28, so that the liquid level in the second tank compartment 23 drops to the height consistent with the liquid level in the first tank compartment 22, and the overflow pipe 28 loses the liquid sealing effect. Since the vertical portion of level divider 21 divides the liquid in the tank into a portion that is within first tank compartment 22 and a portion that is much smaller than the area within second tank compartment 23. For this reason, when the height of the liquid level 1 changes, the influence on the liquid level 2 is small, so that the bottom of the overflow pipe is always below the liquid level 2, namely, the liquid seal state is always realized, and the gas in the tank cannot flow out of the overflow pipe.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
