Through setting up stopper 35 and pinch roller 39 etc. cooperation use, can use pinch roller 39 to pull stay 19, make stay 19 be in the state of tightening always, avoid stay 19 to loosen and twine and tie up, and bolt 38 cooperates with screw 37, in order to restriction pinch roller 39 can the movable position, when the atmospheric pressure in deoxidization case 3 reduces, second piston 33 compresses second spring 34 and moves down, the one end of stay 19 is pulled to the second piston 33 that moves, when one end of stay 19 is pulled down, stopper 35 receives the pulling of stay 19 with pinch roller 39 and moves up, after stopper 35 moves up to certain position, stopper 35 offsets with the one end of bolt 38, with atmospheric pressure in deoxidization case 3 is less than certain degree and makes the second piston 33 move down to certain position after (the pulling force of stay 19 just begins to be greater than the thrust that first spring 31 applyed to slide 18 this moment, before the pulling force of stay 19 is less than the thrust that first spring 31 applyed to slide 18, so when one end of stay 19 is pulled down, the other end of stay 19 receives the pulling down, the other end of stay 19 is pulled down, the other end of stay 19 is not pushed down, the second piston 33 is kept on by the stay 19 and moves down through the push roller 33, can only move up through the stay 19.
Further, the lower surface of the sleeve 11 is communicated with a second air duct 40, one end of the second air duct 40 is communicated with the first air duct 16, the inner wall of the second air duct 40 is fixedly connected with a fourth one-way valve 41, the lower surface of the sleeve 11 is provided with an air suction hole 42, and the inner wall of the air suction hole 42 is fixedly connected with a fifth one-way valve 43. Through the cooperation of the second air duct 40 that sets up and the suction port 42 etc. use, when can making first piston 12 move down, first piston 12 also can push the gas in the sleeve 11 into the aerobe 1, for aerobe 1 aeration is mended, when during the use, when first piston 12 rises, sleeve 11 inhales through suction port 42 (fourth check valve 41 shutoff, fifth check valve 43 is opened), and when first piston 12 moves down, first piston 12 alright push out the gas that sleeve 11 inhaled through second air duct 40 (fourth check valve 41 is opened, fifth check valve 43 shutoff).
Further, the upper surface of the transparent tube 32 is provided with a pressure relief hole 44; by providing the pressure release hole 44, air in the transparent tube 32 can be freely introduced and discharged, and the influence of high pressure or low pressure in the transparent tube 32 on the movement of the second piston 33 is avoided.
Further, the inner wall of the deoxidizing box 3 is fixedly connected with a deflector 45; by arranging the guide plates 45, the wastewater entering the deoxidizing box 3 rolls down along the guide plates 45, so that the oxygen in the wastewater is convenient to overflow.
Working principle: in the invention, when the device is used, a motor 24 is started, the started motor 24 drives a rotary table 25 to rotate, the rotary table 25 drives a rotary rod 26 to rotate, the rotary rod 26 drives a bar rod 27 to move up and down, the bar rod 27 which moves up and down drives a connecting rod 13 and a first piston 12 to move up and down, when the first piston 12 moves down, a first one-way valve 15 is opened, a sleeve 11 sucks air through a limiting pipe 14, when the first piston 12 moves up, the first one-way valve 15 is closed, and the first piston 12 presses air into an aerobic tower 1 through a first air guide pipe 16 to provide air for aeration in the aerobic tower 1;
When the slide tube 18 is not pulled up, when the limit tube 14 sucks air, the second air guide holes 21 are communicated with the air suction tube 22, the limit tube 14 absorbs air in the deoxidization box 3 through the slide tube 18, the first air guide holes 20 and the air suction tube 22, so that the deoxidization box 3 is in a negative pressure state, when the wastewater treated in the aerobic tower 1 needs to be pumped into the anaerobic tower 2, the electromagnetic valve 4 is opened, the deoxidization box 3 in the negative pressure state firstly pumps the wastewater into the deoxidization box 3 through the first guide tube 5, the wastewater enters the deoxidization box 3, the air in the wastewater is easy to overflow outwards due to the reduction of pressure, the oxygen content in the wastewater is reduced, and when the overflowed air moves up and down through the first piston 12, the air is pumped out through the air suction tube 22 and the like, so that the relatively constant negative pressure state is kept in the deoxidization box 3;
The wastewater with oxygen removed falls into the bottom of the deoxidizing box 3, and then the water pump 7 is started, so that the wastewater can be pumped into the anaerobic tower 2, and the anaerobic tower 2 is used for treating the wastewater again;
when the air pressure in the deoxidizing box 3 is reduced, the second piston 33 compresses the second spring 34 to move downwards, the moving second piston 33 pulls one end of the pull rope 19, when one end of the pull rope 19 is pulled downwards, the limiting block 35 and the pinch roller 39 are pulled by the pull rope 19 to move upwards, after the limiting block 35 moves upwards to a certain position, the limiting block 35 is propped against one end of the bolt 38, after the air pressure of the deoxidizing box 3 is lower than a certain degree to enable the second piston 33 to move downwards to a certain position, the second piston 33 which continues to move downwards pulls the slide tube 18 to move upwards through the pull rope 19 (the pull rope 19 is always in a tight state, but when one end of the pull rope 19 is pulled downwards, the limiting block 35 and the pinch roller 39 are pulled by the pull rope 19 to move upwards, after the limiting block 35 moves upwards to a certain position, the limiting block 35 is propped against one end of the bolt 38, after the air pressure of the deoxidization box 3 is lower than a certain degree to enable the second piston 33 to move downwards to a certain position, the second piston 33 which continues to move downwards can pull the sliding tube 18 to move upwards through the pull rope 19), after the sliding tube 18 moves upwards to a certain position, the second air guide hole 21 can be communicated with the outside, so that when enough air is not in the deoxidization box 3, the limiting tube 14 and the sliding tube 18 can absorb the outside air, and then the air can be filled into the aerobic tower 1 through the sleeve 11 and the like to supplement enough air for aeration to avoid the problem that the aeration effect is greatly reduced because the air in the deoxidization box 3 is absorbed completely and the device does not absorb the air.
