The equal installation by adhering in surface of first cabinet 1 and the second cabinet 20 has hopper 19, and the first cabinet 1 is with the second cabinet 20
Volume is equal, the identical structure of shape, and the two sealed set each other, consequently facilitating storing alkaline medicine respectively in two cabinets
Object and acidic drug, while two cabinets are set together, and facilitate management.
Working principle: as shown in Figure 1 and Figure 5, first when being used for the wastewater treatment soda acid chemicals dosing plant of steam power plant using this
Gas pipeline 9 and external air pump are first subjected to installation fixation, acid is injected in its inside by the feed inlet 2 of the first cabinet 1
Property solution, by the liquid level inside 19 observable of hopper, until liquid level be located at hopper 19 maximum scale it
Stop injection solution afterwards, alkaline solution is similarly injected in its inside by the feed inlet 2 of the second cabinet 20, until liquid level and the
The liquid level of one cabinet 1 flushes, and later closes the feed inlet 2 on the first cabinet 1 and the second cabinet 20;
When needing to acidic drug is added in boiler, as shown in Figure 1, Figure 2 and Figure 4, air inlet pipe 7 in the first cabinet 1 is opened
Solenoid valve 8, so that the air inlet pipe 7 in the first cabinet 1 is open state, so that gas is inputted out of gas pipeline 9, air passes through
Duplex fitting 10 enters the air inlet pipe 7 in the first cabinet 1, and subsequent air sprays to the turbine wheel 6 in the first cabinet 1, and turbine wheel 6 exists
It is rotated in liquid, so that turbine wheel 6 drives carrier 5 and rotation axis 4 to be rotated simultaneously, rotation axis 4 drives paddle
Piece 12 is rotated, and stirring blade 12 and turbine wheel 6 are stirred mixing, and the lower section of gas from liquid to acidic liquid
It floating upwards, final gas is saved bit by bit above liquid, and the gas sprayed out of air inlet pipe 7 gradually increases in the first cabinet 1,
Air pressure in first cabinet 1 is gradually increased, i.e. liquid in the first cabinet 1 enters fixed cylinder 14 by connected relief pipeline 13
Interior, as shown in figure 3, liquid promotes piston 18 to move down in drainage wall 15, and piston 18 presses reset spring 17
Contracting, until the height of piston 18 is lower than the height of drainage conduit 16, acidic liquid is flowed out from drainage conduit 16 in the first cabinet 1, acid
Liquid was discharged after a period of time, and the liquid volume in the first cabinet 1 is gradually reduced, and gas volume is gradually increased, until first
Air pressure reverts to normal pressure in cabinet 1, and pressure under piston 18 disappears, and reset spring 17 resiles, band piston 18 continue to
Upper movement, until piston 18 blocks drainage conduit 16, to again be sealing state in the first cabinet 1;
When needing to add alkaline drug in boiler, the solenoid valve 8 being first shut off in the air inlet pipe 7 in the first cabinet 1, first
Air inlet pipe 7 in cabinet 1 is sealing state, opens the solenoid valve 8 in the second cabinet 20 in air inlet pipe 7, the second cabinet 20 later
Interior air inlet pipe 7 is open state, so that gas enters in the second cabinet 20, gas drives the turbine wheel 6 in the second cabinet 20
It is rotated, similarly such as upper section, the piston 18 in the fixed cylinder 14 of 20 lower section of the second cabinet is also squeezed by liquid, thus liquid
Body is discharged from drainage conduit 16, realizes the timing outflow of liquid.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
