The solid impurities in the gas collecting hood 22 can be precipitated downwards, and scum floating on the liquid level can be accommodated in the accommodating box 42, so that the effect of reducing the solid impurities in the liquid is achieved, the separation effect of the liquid and the solid is improved, and the advantage of more thorough separation is achieved.

The length of the exhaust groove 35 is greater than the thickness of the sealing plate 33, so that when the sealing plate 33 moves to the middle of the exhaust groove 35, gas can flow from one side of the sealing plate 33 to the other side through the exhaust groove 35, thereby achieving the function of opening the gas pipe 25. When the air pipe 25 needs to be closed and the air in the air collecting hood 22 is blocked from flowing to the air pipe 25, the sealing plate 33 slides in the air pipe 25, so that the exhaust groove 35 is positioned at one side of the sealing plate 33, and the air can not flow from one side of the sealing plate 33 to the other side through the exhaust groove 35, thereby realizing the function of closing the air pipe 25.

When the weight frame 31 moves downwards, the weight frame can be clamped with the lower clamping plate 37 and pushes the lower clamping plate 37, the driving rod 34 and the sealing plate 33 to move downwards; when the weight rack 31 moves upwards, the weight rack can be clamped with the upper clamping plate 36 and pushes the upper clamping plate 36, the driving rod 34 and the sealing plate 33 to move upwards. The upper clamping plate 36 and the lower clamping plate 37 are used for realizing the function that the weight frame 31 drives the driving rod 34 to vertically move.

When the seal plate 33 closes the gas pipe 25, the gas in the sliding sleeve 23 and the gas collecting cover 22 is gradually increased, the liquid level height is gradually reduced, and the weight rack 31 is moved downwards. When the weight frame 31 moves to abut against the lower clamping plate 37, the weight frame continues to move downwards, the lower clamping plate 37 and the driving rod 34 are driven to move downwards, the sealing plate 33 is moved to the middle of the exhaust groove 35, gas in the sliding sleeve 23 can be exhausted through the gas pipe 25, the liquid level in the sliding sleeve 23 and the gas collecting cover 22 rises, the weight frame 31 rises along with the liquid level, and at the moment, the driving rod 34 stops moving downwards. When the weight frame 31 rises to abut against the upper clamping plate 36 and push the upper clamping plate 36 and the driving rod 34 to move upwards until the sealing plate 33 is driven to move to one side of the exhaust slot 35, so that the gas transmission pipe 25 is sealed through the sealing plate 33, the weight frame 31 and the liquid level stop rising, and the weight frame 31 can descend along with the increase of gas in the sliding sleeve 23 and the gas collecting cover 22 again, and the function of driving the weight frame 31 to do up-and-down circular motion is realized.

Through the setting of 3 closing plates 33, can play the effect that improves the leakproofness, the interval of closing plate 33 is greater than the length of exhaust groove 35, prevents that closing plate 33 from removing to adjacent exhaust groove 35 department before can sealing the gas-supply pipe 25 in vertical movement's process.

The sealing member 38 blocks the gap between the sealing plate 33 and the gas pipe 25, thereby preventing gas from leaking from the gap between the sealing plate 33 and the gas pipe 25, and improving the sealing performance.

In the process that the weight frame 31 moves downwards, the scraper 43 is driven to scrape the scum attached to the filter screen 29, so that the scum moves towards the scum port 41 and enters the storage box 42, the scum is prevented from blocking the filter screen 29, the effect of clearing the scum in the liquid can be realized, and the separation is more thorough.

In the process that the weight frame 31 moves downwards, the brush bristles 44 are driven to brush off scum attached to the filter screen 29, so that the scum moves towards the scum port 41 and enters the storage box 42, the scum is prevented from blocking the filter screen 29, the effect of clearing the scum in the liquid can be realized, and the separation is more thorough.

In the dross got into receiver 42 back, through the effect of buoyancy, the dross that makes in the receiver 42 removes to the direction of keeping away from sliding sleeve 23 along receiver 42 roof, prevents that the dross from getting into sliding sleeve 23 again in and mixing with liquid, reaches the more thorough effect of separation.

When the dross in receiver 42 is more, pull down receiver 42 from sliding sleeve 23, can play the effect of conveniently clearing up the dross in the receiver 42, prevent that the dross is too much and spill over to in the sliding sleeve 23 in the receiver 42.

In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
