The specific embodiment
To combine Figure of description and specific embodiment that the utility model is done further explain below.
A kind of knockout drum, as shown in Figure 1.Comprise tank body, be divided into epicoele 11 and cavity of resorption 12 through interlayer in the tank body, the outer wall of tank body is provided with fluid passage 14, and fluid passage is communicated with epicoele and cavity of resorption, is provided with check valve I 13 in the fluid passage, and check valve I is positioned at the liquid outlet end of epicoele.
The upper cover of tank body is provided with vavuum pump interface 16 and air interchanger, and the sidewall of epicoele is provided with inlet; The bottom of cavity of resorption is provided with leakage fluid dram, and check valve II 18 is installed on the leakage fluid dram.
Air interchanger is as shown in Figure 2, comprises pipe nipple 5, flange 4 and blind flange 3.The lower end of pipe nipple is welded on the upper cover, the upper end welded flange of pipe nipple, and the flange top is through the bolted flange lid.Blind flange is provided with blind flange short tube 10, and blind flange short tube 10 is corresponding about in the of 8 with the epicoele short tube.Be movably set with piston 2 in the blind flange short tube, piston comprises piston rod and sealing gasket, and the end that piston rod stretches into air interchanger is connected with sealing gasket 6, and sealing gasket 6 is between blind flange short tube 10 and epicoele short tube 8; Piston rod is positioned at an extraneous end and connects cylinder 1, and cylinder is fixedly connected on the blind flange short tube 10 through support, is used for when sealing gasket sealing epicoele short tube, and ambient atmosphere gets into the cavity of resorption short tube.Piston moves up and down under the drive of cylinder, carries out the control that is communicated with of cavity of resorption short tube and the external world or epicoele short tube.
Cylinder is connected with source of the gas, and source of the gas is controlled air inlet through the time relay or bled.Cylinder carries out the piston motion under the control of source of the gas, and then drives piston up-down.
Before the utility model work,, promptly filtrate from epicoele to the time that cavity of resorption flows at first according to the opening and the shut-in time of the volumetric ratio setting-up time relay of knockout drum epicoele and cavity of resorption, and the drain time of cavity of resorption.
During the utility model work, the vavuum pump that is connected with tank body is in running order all the time.Under the effect of piston rod at external source of the gas, mentioned by cylinder, when sealing gasket moves upward to the top of air interchanger, sealing gasket will be positioned at the sealing of air interchanger blind flange short tube.At this moment, knockout drum epicoele and cavity of resorption are communicated with through epicoele short tube and cavity of resorption short tube, and epicoele and cavity of resorption by the vavuum pump suction, are in negative pressure state simultaneously, and the check valve II that is positioned at leakage fluid dram closes under the atmospheric pressure effect; Do not have pressure reduction between epicoele and the cavity of resorption simultaneously, filtrating presses off check valve I through deadweight, flows into cavity of resorption.
When being depressed by cylinder under the effect of piston at external source of the gas, piston rod moves downward, and sealing gasket arrives the top of epicoele short tube, and sealing gasket seals the epicoele short tube.This moment, knockout drum epicoele short tube was sealed, and had only epicoele to be aspirated by vavuum pump, was in negative pressure state, and the check valve I at epicoele liquid outlet place closes under the atmospheric pressure effect; Communicate with the external world owing to the cavity of resorption short tube simultaneously; Atmospheric pressure gets into air interchanger through the blind flange short tube; Get into the cavity of resorption short tube that connects the knockout drum cavity of resorption then, the check valve II at cavity of resorption leakage fluid dram place opens under the gravity effect of filtrating, and discharges knockout drum.
Sealing gasket in the utility model adopts polyurethane material, good sealing effect, and fault rate is low, has effectively guaranteed the timely discharge of filtrating.
Certainly, the utility model is described, and to be used for the automatic controls that control piston moves up and down can also be hydraulic means etc., and said air interchanger can also be arranged on the sidewall of tank body and wait other positions.
