Description
Technical field
The present invention relates to Mine Stope to fill field, is used to eliminate under filling slurry to pumping line more particularly, to one kind
The device of vapour lock.
Background technology
Filling in mine, the overwhelming majority use pipeline filling slurry, and the mode of movement of filling slurry mainly has gravity flow defeated
Send and pump, pumping is mainly used in pipeline distance, without the operating mode of the potential energy required for enough discrepancy in elevation offer slurry pipeline transport.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
The lower phenomenon that negative pressure and vapour lock are produced into pumping procedure, it is lower preferably to solve to do to negative pressure problem caused by pumping is existing at present
Method.But the lower vapour lock problem to pumping, solves method there has been no preferable.
Vapour lock, i.e. gas block, slurry Gravitative Loads quickly flow forward in the downward course of conveying of slurry, and pump flow
Speed is slower, and slurry above has blocked conduit section by a part of gas confinement in pipeline in pipeline, with pumping procedure gas
Body is compressed with certain pressure, and so as to form vapour lock, vapour lock is generally assembled to the high point of pipeline.Part mine is in pumping
High point arranges automatic inlet-outlet valve, but because the process of vapour lock discharge is generally discharged together along with mortar, automatic air intake and discharge
Valve（Ball float principle, there is slurry by just withstanding outlet, be that gas turns on outlet）Discharging opening be very easy to withstand closing,
So as to be vented failure.
The U of CN 202865301 disclose it is a kind of exclude pulp-inlet pipe road gas resistance device, including pulp-inlet pipe road and pulp-inlet pipe road
Grout outlet is arranged on the bottom of leaching tanks, and the corner in pulp-inlet pipe road is connected with a discharge duct, discharge duct one end with
Pulp-inlet pipe road is connected, and the other end sets the outside with leaching tanks.Because filling slurry pumping line is located at underground, this exclude into
The device of slurry pipeline vapour lock is not suitable under filling slurry to pumping line vapour lock.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, it is simple in construction, it is easy to use, it is easy to
Under filling slurry into pumping line caused vapour lock exclude in time be used for eliminate under filling slurry to pumping line vapour lock
Device, avoid vapour lock from increasing pipeline pressure, avoid vapour lock from causing the vibration of pipe conveying procedure, avoid vapour lock from causing to expect in pipeline
Slurry isolation.
The technical solution adopted for the present invention to solve the technical problems is：One kind is used to eliminate under filling slurry to pumping line
The device of road vapour lock, including guide valve, knockout drum and air bleeding valve；To pumping line under one end of the guide valve and filling slurry
Connection, its other end are connected with knockout drum bottom；The air bleeding valve is arranged on top or the upper side wall of knockout drum.
Further improvement project is：The guide valve and air bleeding valve are magnetic 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 magnetic valve or pneumatic operated valve, the guide valve, exhaust
Valve electrically connects with relay.
Further, the guide valve is arranged 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, are opened when different, one open when, another necessarily be in closing shape
State；
A kind of operation principle for being used to eliminate the device under filling slurry to pumping line vapour lock of the present invention and application method are：Fill
Knockout drum is rapidly entered in the presence of draught head to pumping line under extender paste, the volume of knockout drum is larger, is easy in slurry
Feed liquid separated with gas, the gas after separation is discharged by air bleeding valve, and feed liquid flows back to through guide valve again under gravity fills
Under extender paste into pumping line.Opened when air bleeding valve and guide valve difference, one open when, another necessarily be in closing shape
State, ensure that manifold pressure is stable, and realize the slurry backflow after separation, periodically（It is intermittent）The effect of exhaust.
（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 either manually or by controller control or delay timing, then opens separation tank deck
The air bleeding valve in portion, vapour lock discharge, and slurry can not discharge at a high speed so staying in vapour lock point upwards because section is larger with vapour lock
From in tank, after vapour lock is drained, vapour lock separation pressure inside the tank recovers normal pressure（Atmospheric pressure）.（3）Then, either manually or by controller control
Air bleeding valve is closed in system or delay timing, then opens guide valve, and now the part slurry in vapour lock knockout drum is back to lower to pump
Send in pipeline, the slurry in tank to be separated is all back to lower to guide valve after pumping line, is turned off, and starts next cycle
The vapour lock for mixing mud enter vapour lock knockout drum.
A kind of beneficial effect for being used to eliminate the device under filling slurry to pumping line vapour lock of the present invention：It is simple in construction,
Easy to use, fault rate is low, and can eliminate the vapour lock under filling slurry into pumping line in time, avoids under slurry to pumping
During caused vapour lock cause pipeline pressure increase and vibrate, while avoid in filling slurry course of conveying occur sink
Segregation phenomenon drops.
