The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the present invention is described in further detail.
A kind of knockout drum, as shown in Figure 1.Comprise tank body, be divided into epicoele 11 and cavity of resorption 12 by interlayer in tank body, be provided with fluid passage 14 on the outer wall of tank body, fluid passage is communicated with epicoele and cavity of resorption, is provided with check valve I 13 in fluid passage, and check valve I is positioned at the liquid outlet end of epicoele.
Be provided with vavuum pump interface 16 and air interchanger on the upper cover of tank body, be provided with inlet on the sidewall of epicoele; The bottom of cavity of resorption is provided with leakage fluid dram, and check valve II 18 is installed on leakage fluid dram.
Air interchanger comprises pipe nipple 5, flange 4 and blind flange 3 as shown in Figure 2.The lower end of pipe nipple is welded on upper cover, is bolted blind flange above the upper end welded flange of pipe nipple, flange.Be provided with blind flange short tube 10 on blind flange, blind flange short tube 10 is corresponding Shang Xia 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 blind flange short tube 10 by support, is used for when sealing gasket sealing epicoele short tube, and ambient atmosphere enters 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 or bleeds by the time relay.Cylinder carries out piston movement under the control of source of the gas, and then drives piston up-down.
Before work of the present invention, 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, i.e. filtrate time of flowing from epicoele to cavity of resorption, and the drain time of cavity of resorption.
When the present invention worked, the vavuum pump that is connected with tank body was in running order all the time.Mentioned by cylinder under the effect of piston rod at external gas source, 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 by epicoele short tube and cavity of resorption short tube, and epicoele and cavity of resorption are aspirated by vavuum pump simultaneously, are in negative pressure state, and the check valve II that is positioned at leakage fluid dram closes under the atmospheric pressure effect; There is no pressure reduction between epicoele and cavity of resorption simultaneously, filtrate presses off check valve I by deadweight, flows into cavity of resorption.
When being depressed by cylinder under the effect of piston at external gas source, 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, only had 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; Simultaneously because the cavity of resorption short tube communicates with the external world, atmospheric pressure enters air interchanger by the blind flange short tube, then enter the cavity of resorption short tube that connects the knockout drum cavity of resorption, the check valve II at cavity of resorption leakage fluid dram place opens under the Action of Gravity Field of filtrate, and discharges knockout drum.
Sealing gasket in the present invention adopts polyurethane material, good sealing effect, and failure rate is low has effectively guaranteed the timely discharge of filtrate.
Certainly, the automatic controls that moves up and down for control piston of the present invention can also be hydraulic means etc., and described air interchanger can also be arranged on and wait other positions on the sidewall of tank body.
