Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a liquid level balance drainage device of an air flotation machine, which comprises a drainage cavity 1 communicated with an air flotation tank, a drainage groove 2 fixedly arranged in the upper end of the drainage cavity 1 and a water outlet pipeline 3 fixedly arranged on the outer side of the drainage cavity 1 and communicated with the bottom of the drainage groove 2, wherein one side of the drainage groove 2 is provided with an overflow port 4, and a supporting plate 5 connected with the inner wall of the drainage cavity 1 is fixedly arranged at the position, corresponding to the upper part of the overflow port 4, of the top of the drainage groove 2;

a sealing plate 6 for longitudinally moving and sealing the overflow port 4 is slidably mounted at the position, corresponding to the overflow port 4, of the drainage groove 2, and the sealing plate 6 is positioned below the supporting plate 5;

the shrouding 6 is kept away from the fixed locating piece 7 that is provided with in one side of water drainage tank 2, rotate on the backup pad 5 install run through in locating piece 7 and with 7 threaded connection's of locating piece removal axle 8.

When the drainage device is used, liquid at the bottom of the air flotation cavity enters the air flotation cavity 1 from the bottom of the air flotation cavity through the liquid guide channel through the guide pipe, and when the liquid level rises to the highest level of the sealing plate 6, the liquid enters the drainage groove 2 from the highest level position of the sealing plate 6 through the overflow port 4 and is discharged out of the drainage groove 2 through the water outlet pipeline 3, so that the drainage work is finished; during the use, the accessible rotates removal axle 8, make removal axle 8 drive locating piece 7 reciprocate on removing axle 8, thereby drive shrouding 6 and reciprocate in the position department that drainage tank 2 goes up corresponding overflow mouth 4, and then change the height on overflow mouth 4 base, carry out liquid level control, adjust air supporting intracavity liquid level, air supporting chamber and drainage intracavity liquid level balance during the use, when continuing to air supporting intracavity water inlet treatment, make air supporting chamber and drainage chamber 1 interior liquid increase after carry out the drainage through overflow mouth 4 entering drainage tank 2. Compared with the traditional method that the drainage pipeline and the valve are arranged at the bottom of the drainage cavity 1 through the valve, the liquid level in the air flotation cavity can be effectively controlled, and the use is convenient.
