The output end rotary seal of motor 12 processed is fixedly connected with left sealing plate 3 and right sealing plate 4 respectively through separate pipeline 1；Water conservancy diversion
The outer wall of pipe 5 is provided with flow controlling motor 13, and the output end rotary seal of flow controlling motor 13 is close through mozzle 5 and water conservancy diversion
Shrouding 7 is fixedly connected；The outer wall of drainage sediment outflow pipe 6 is provided with sediment outflow controlled motor 14 corresponding with sediment outflow sealing plate 8, two rows
The output end rotary seal of sand controlled motor 14 is fixedly connected with sediment outflow sealing plate 8 respectively through drainage sediment outflow pipe 6；In screen pack
Chute box 15 is fixed with 2 right sides, separation sleeve pipe inwall；Vibrating motor 16 is slidably connected in chute box 15；Vibrating motor 16
Output end be connected with eccentric wheel 17；Stage clip 18 is connected between vibrating motor 16 and the right wall of chute box 15；Described screen pack 2
Cross sectional shape be isosceles trapezoid, and small end is under.
When in use, when oil gas is filtered from the left end of screen pack 2 to right-hand member, control flow controlling is electric for the utility model
Machine 13 drives water conservancy diversion sealing plate 7 to rotate, and makes on the right side of the closing passage of mozzle 5, the drive of sediment outflow controlled motor 14 of control right-hand member
Sediment outflow sealing plate 8 is by the right side port sealing of drainage sediment outflow pipe 6, and the left side port of drainage sediment outflow pipe 6 is turned on, for gravel drop
Fall in storage sand tube 9, oil gas enters from the left end of separate pipeline 1, and from left to right by the filtration of screen pack 2, gravel is by mistake
The left end in screen pack 2 is filtered, oil gas is discharged by screen pack 2 from right-hand member, and gravel falls to drainage sediment outflow pipe 6, entered finally into
Retained in storage sand tube 9, now the left part gravel of screen pack 2 accumulates more；When changing the circulation circuit of oil gas, make oil gas from filtering
The right side of net 2 to left side is flowed, and by controlling two sealing controlled motors 12,4 turns of left sealing plate 3 and right sealing plate are driven respectively
It is dynamic, seal and coordinate with separate pipeline 1, oil gas directly can not flow to right-hand member from left end, and control flow controlling motor 13 drives water conservancy diversion
Sealing plate 7 is rotated, and turns on mozzle 5, connects the sky between the space in the left left side of sealing plate 3 and screen pack 2 and right sealing plate 4
Between.The sediment outflow sealing plate 8 on the right side of the drive of sediment outflow controlled motor 14 on the right side of control is rotated, and is turned on drainage sediment outflow pipe 6, was connected
The space in space and the right side of right sealing plate 4 between filter screen 2 and left sealing plate 3, is directed at the right-hand member of separate pipeline 1, now by oil gas
Oil gas is entered by the left end of separate pipeline 1, from mozzle 5 by flowing to the right-hand member of screen pack 2, from right to left by the mistake of screen pack 2
Filter, gravel stays in the right side of screen pack 2, and oil gas flow to the left side of screen pack 2, and enters the row of flowing to by the left port of drainage sediment outflow pipe 6
The right output port of sediment outflow pipe 6 is flowed, finally still the right side of the oil gas without gravel, now screen pack 2 is discharged from the right output port of separate pipeline 1
Portion causes accumulating for gravel, and in filter process, can produce impact to the left part of screen pack 2, makes what the left part of screen pack 2 was accumulated
A part of gravel, which is impacted, to drop, and reduces the blocking of screen pack 2, then is then the cleaning of the impact to the right part of screen pack 2 in turn, leads to
The control of each motor is crossed, again closes mozzle 5, sealing controlled motor 12 drives left sealing plate 3 and right sealing plate 4 dozens
Open, when oil gas directly flow to right-hand member from the left end of separate pipeline 1, can first control the sediment outflow controlled motor of the upper left side of drainage sediment outflow pipe 6
14, the sediment outflow seal pipe on the left of drive closes the left port of drainage sediment outflow pipe 6, and right output port is turned on, the sand for accumulating right side
Gravel is brought into the right side port of drainage sediment outflow pipe 6 by oil gas air-flow, is most fallen to afterwards through drainage sediment outflow pipe 6 in storage sand tube 9, sediment outflow
Sediment outflow sealing plate 8 on the right side of clean or setting regular hour, control closes the right output port of drainage sediment outflow pipe 6, the row in left side
Sand sealing plate 8 opens left end import, that is, is returned to appeal and most starts state, recycle.
In control process, oil gas is flowed into from the right-hand member of filter, from right to left by the route use time of filter
Should be shorter, because the effect of the flow direction is, the reverse impact that certain effect is carried out to filter is cleared up, and the hydrocarbon filter
Under route, do not possess the passage of direct sediment outflow, therefore should not carry out working for a long time under the route.When oil gas is passed through from left to right
Under the route for crossing filter, the both sides in sediment outflow processing, control drainage sediment outflow pipe 6 can be carried out in the period to storage sand tube 9
Sediment outflow sealing plate 8, make drainage sediment outflow pipe 6 two-port be in seal closed mode, then drainage sediment outflow pipe 6 not with separating pipe
Road 1 is turned on, and can now be opened, the seal plug 10 at the two ends of storage sand tube 9, and cleaning discharge is carried out to the gravel in storage sand tube 9.
The gravel scale removal process, is that the further waste reduced to oil gas is lost, storage sand tube 9 can be made to connect air extractor, first after sealing
First the oil gas inside storage sand tube 9 is extracted out and collected, in injection air adjustment air pressure inside, seal plug 10 is then opened and is arranged
Sand processing.
Opening vibrating motor 16 can rotate with movable eccentric wheel 17, the side of eccentric wheel 17 is quickly interrupted screen pack 2
Percussion, eccentric wheel 17 tap arrive screen pack 2 when, eccentric wheel 17 is rotated further, make vibrating motor 16 in chute box 15 to the right
Compression press spring 18 is moved in side, when eccentric wheel 17 is contacted with screen pack 2 foremost, and vibrating motor 16 is in farthest shift length position
Put, eccentric wheel 17 progressively disengages screen pack 2 afterwards, the pushing motor of stage clip 18 resets, and continues the percussion of a new round, quick high frequency
The vibrations caused to screen pack 2 are tapped, easily departs from the gravel accumulated, is easy to impact to clear up.Also can be directly by vibrating motor
16 are arranged on the side of screen pack 2, and the vibration of screen pack 2 is driven by vibrating, and accelerate the disengaging of gravel.
Rotary seal connection specifically described herein etc., can install conventional sealing device such as rubber ring etc. by increasing,
Improve sealing property.Involved control circuit is conventional technology.
