Description
Technical field
The utility model is related to Mine Stopes to fill field, is used to eliminate under filling slurry to pumping more particularly, to one kind
The device of pipeline vapour lock.
Background technology
Filling in mine, for the overwhelming majority using pipeline filling slurry, the mode of movement of filling slurry mainly has the gravity flow defeated
It send and pumps, pumping is mainly used for pipeline distance, and the operating mode of the required potential energy of slurry pipeline transport is provided without enough height difference.Ground
The mine of lower exploitation inevitably faces the lower operating mode to pumping, and lower the problem of being brought to pumping for filling slurry will be mainly
It is lower the phenomenon that negative pressure and vapour lock are generated into pumping procedure, lower to be done to the negative pressure problem preferable solution existing at present for pumping generation
Method.But the lower vapour lock problem to pumping, there has been no preferable solutions.
Vapour lock, i.e. gas block, slurry Gravitative Loads quickly flow forward in the downward transmission process of slurry, and pump flow
Speed is slower, and the slurry of front has blocked conduit section by gas confinement a part of in pipeline in pipeline, with pumping procedure gas
Body is compressed with certain pressure, and so as to form vapour lock, vapour lock is usually assembled to the high point of pipeline.Part mine is in pumping
High point arranges automatic inlet-outlet valve, but since the process of vapour lock discharge is usually discharged together along with mortar, automatic air intake and discharge
Valve（Floating ball principle, there is slurry by just withstanding outlet, be that gas turns on outlet）Discharge port be very easy to withstand closing,
So as to be vented failure.
202865301 U of CN disclose a kind of exclusion pulp-inlet pipeline gas resistance device, including pulp-inlet pipeline and pulp-inlet pipeline
Grout outlet is arranged on the bottom of leaching tanks, and a discharge duct is connected in the corner of pulp-inlet pipeline, discharge duct one end with
Pulp-inlet pipeline is connected, other end setting and the outside of leaching tanks.Due to filling slurry pumping line be set on underground, this exclude into
The device of slurry pipeline vapour lock is not suitable under filling slurry to pumping line vapour lock.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiencies in the prior art, it is simple in structure, it is easy to use,
What the vapour lock convenient for being generated under filling slurry into pumping line excluded in time is used to eliminate under filling slurry to pumping line gas
The device of resistance avoids vapour lock from increasing pipeline pressure, vapour lock is avoided to cause the vibration of pipe conveying procedure, vapour lock is avoided to cause pipeline
Interior slurry isolation.
Technical solution is used by the utility model solves its technical problem：One kind is used to eliminate under filling slurry to pump
The device of pipeline vapour lock is sent, including guide valve, knockout drum and air bleeding valve；To pumping under one end of the guide valve and filling slurry
Pipeline connects, and the other end is connect with knockout drum bottom；The air bleeding valve is mounted on top or the upper side wall of knockout drum.
Further improvement project is：The guide valve and air bleeding valve are solenoid valve or pneumatic operated valve, the guide valve, exhaust
Valve is electrically connected with the controller.
Further improvement project is：The guide valve and air bleeding valve are solenoid valve or pneumatic operated valve, the guide valve, exhaust
Valve is electrically connected with relay.
Further, the guide valve is mounted on the corner under filling slurry to pumping line or peak.
Further, the cross-sectional area of the knockout drum is more than or equal under filling slurry to 10 times of pumping line sectional area.
Further, the air bleeding valve and guide valve, do not open simultaneously, one open when, another necessarily is in closing shape
State；
A kind of operation principle and use for being used to eliminate the device under filling slurry to pumping line vapour lock of the utility model
Method is：Knockout drum is rapidly entered under the action of draught head to pumping line under filling slurry, the volume of knockout drum is larger, just
Feed liquid in slurry is detached with gas, and the gas after separation is discharged by air bleeding valve, and feed liquid is under the effect of gravity again through being oriented to
Valve is flowed back under filling slurry into pumping line.Air bleeding valve and guide valve do not open simultaneously, one open when, another must locate
In closed state, ensure that manifold pressure is stablized, and realize the slurry reflux after separation, periodically（It is intermittent）The effect of exhaust
Fruit.
（1）In the case of exhaust valve closure, guide valve is opened either manually or by controller control or delay timing（Row
Air valve is closed）, due to larger to the vapour lock pressure of pumping line under filling slurry, and vapour lock separation pressure inside the tank is
Normal pressure（Atmospheric pressure）, vapour lock（Essence is compressed air）Enter vapour lock knockout drum at a high speed, due to calming the anger narrow light-gauge
By slurry also with walking, the vapour lock with slurry enters in vapour lock knockout drum flow at high speed in pipeline, and then artificial close is oriented to
Valve, vapour lock and slurry enter the vapour lock knockout drum of big cross section, vapour lock aloft assemble and slurry in bottom, so as to complete vapour lock and
The separation of slurry；（2）Then, guide valve is closed, then open separation tank deck either manually or by controller control or delay timing
The air bleeding valve in portion, vapour lock discharge, and slurry can not be upwards discharged at a high speed with vapour lock so staying in vapour lock point since section is larger
From in tank, after vapour lock is drained, vapour lock separation pressure inside the tank restores normal pressure（Atmospheric pressure）.（3）Then, either manually or by controller control
System or delay timing close air bleeding valve, then open guide valve, and the part slurry in vapour lock knockout drum is back to lower to pump at this time
It send in pipeline, the slurry in tank to be separated is all back to lower after pumping line, turns off guide valve, starts next cycle
The vapour lock for mixing mud enter vapour lock knockout drum.
A kind of advantageous effect for being used to eliminate the device under filling slurry to pumping line vapour lock of the utility model：Structure letter
Single, easy to use, failure rate is low, and can eliminate the vapour lock under filling slurry into pumping line in time, avoid under slurry to
The vapour lock generated in pumping procedure causes pipeline pressure to increase and vibrate, while avoid and sent out in filling slurry transmission process
Raw sedimentation segregation phenomenon.
