The reference numbers in the figures are as follows: 1. four-way valve, 2, control deflector rod, 3, liquid inlet, 4, gas-water separation tank, 5, air extraction opening, 6, liquid discharge tank, 7, one-way valve, 8 and inspection hole.
Detailed Description
Referring to fig. 1, the utility model discloses mainly include cross valve 1, gas-water separation case 4 and flowing back 6 three major parts of jar, gas-water separation case 4 and two flowing back jar 6 are installed in disk vacuum filter below. The gas-water separation tank 4 is placed on the liquid discharge tank 6, a liquid inlet pipe at the top of each liquid discharge tank 6 is connected with a liquid discharge port at the bottom of the gas-water separation tank 4, and the four-way valve 1 is installed beside a gas-staggered disc of the filter.
The gas-water separation box is cylindrical in shape and is transversely placed, two sections of 3-inch short sections are welded on the lower side of the gas-water separation box to serve as liquid inlet pipes of the liquid discharge tanks 6, and the positions of the two sections of the liquid discharge tanks 6 are determined according to the two liquid discharge tanks 6 below. The upper part of the gas-water separation box is provided with a liquid inlet 3 and an air exhaust port 5 which are respectively connected with the disc type vacuum filter and the vacuum pump.
The flowing back jar 6 is the cylinder shape, vertical placing, welds 3 cun elbows preparation check valves on the feed liquor pipe on inside top, and 3 cun elbows preparation check valves of outside bottom welding, the round hole that diameter 800mm was left to the side is as inspection hole 8, and inspection hole 8 is equipped with the apron, and the apron passes through the bolt to be connected with the lateral wall of flowing back jar 6.
The four-way valve is arranged above the air-staggering disc, the port A of the four-way valve 1 is communicated with the atmosphere, the port C of the four-way valve 1 is communicated with the gas-water separation tank 4, the port B and the port D of the four-way valve are respectively communicated with the two liquid discharge tanks 6, and the two liquid discharge tanks 6 can be alternately communicated with the atmosphere and the gas-water separation tank 4 by operating the four-way valve 1.
The working process of the device is as follows: the vacuum pump discharges the air in the gas-water separation tank 4, so that a certain vacuum degree is kept in the tank, the liquid mixture discharged from the filter flows into the gas-water separation tank 4, the operation deflector rod 2 is stirred to rotate when the disc type vacuum filter operates, when the deflector rod 2 is operated to rotate to a certain angle, the port A of the four-way valve 1 is communicated with the port D, the port B is communicated with the port C, at the moment, the left liquid discharge tank 6 is communicated with the atmosphere, and the right liquid discharge tank 6 is communicated with the gas-water separation tank 4, so that the pressure in the left liquid discharge tank 6 is greater than the pressure in the gas-water separation tank 4, the check valve at the top of the four-way valve is automatically closed, the check valve; the pressure in the right-side drain tank 6 is equal to the pressure in the gas-water separation tank 4, which is lower than the atmospheric pressure, so that the check valve at the top thereof is automatically opened, and the check valve at the bottom thereof is automatically closed, and the liquid in the gas-water separation tank 4 flows into the right-side drain tank 6.
