Background technology
Mine filling is as a kind of processing method of goaf, and the application in mine is very extensive.In stowing operation, after mine completes filling operation, need to pipeline, be rinsed immediately, the purpose of flushing is mainly that the pipeline sediment in flat pipe is cleaned out.At present,---spoil slurry---coal ash pulp---water---wind that the developing technique flow process of Paste Backfilling With Piping is: lotion, owing to there is no the energy storage equipment of water in existing filling pipeline, while causing water to rinse, the impulse force produced is smaller, be subject to the restriction of mine orographic condition simultaneously, when pipeline long, when knick point is many, this developing technique can not thoroughly be cleaned out the large spoil particle that in pipeline, segregation produces, time has been grown, large spoil particle will bond on inner-walls of duct, accumulate over a long period, the internal diameter of pipeline will be more and more less, percent of pass worse and worse, finally cause line clogging, cause whole filling pipeline thoroughly to be scrapped.
In the prior art, CN102072338A discloses a kind of blowoff valve that rinses use, and it can switch flushing pollution discharge pipeline and filling pipeline as required, but it does not have the pressure accumulation function, can't realize the high pressure washing of filling pipeline; CN201306151Y discloses a kind of safety valve with energy storage equipment, but it is not for mine filling, but among oil drilling, and it can't realize high pressure washing equally.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of full packages auto-flushing method, comprises the following steps:
Standpipe peace pipe is set in the filling pipeline, and the angle of the axis of the axis peace pipe of standpipe is 45～120 degree;
Between standpipe peace pipe, the fluid energy storage equipment is set;
The fluid energy storage equipment cuts off the fluid communication between standpipe peace pipe, and fluid gathers in standpipe, and the pressure in standpipe is constantly increased;
When the pressure in standpipe increases to a preset value, pressure is opened the fluid energy storage equipment, is communicated with standpipe and flat pipe, and with fluid, the pressure with described preset value enters in flat pipe the flushing in standpipe, is rinsed.
Described fluid energy storage equipment is preferably a hydraulic cylinder, described hydraulic cylinder has large chamber and loculus, the internal diameter in large chamber is greater than the internal diameter of loculus, be provided with large piston in large chamber, be provided with valve piston in loculus, connect by piston rod between large piston and valve piston, in described loculus, be provided with sealing gasket, described piston rod coordinates with described sealing gasket the sealing realized between large chamber and loculus; Described loculus is provided with oil-in and oil-out, and described oil-in is connected with Hydraulic Station by check valve, and described oil-out is connected with fuel tank, on the pipeline that described oil-out is communicated with fuel tank, is provided with overflow valve; The end in described large chamber is provided with charging aperture, and described charging aperture is connected with described standpipe, on the chamber wall in described large chamber, is provided with discharging opening, and described discharging opening is connected with described flat pipe.
The pressure relative set that the Area Ratio of described large piston and described valve piston provides according to height and the Hydraulic Station of standpipe.
The Area Ratio of described large piston and described valve piston is 1.5～8.
The invention has the advantages that: simple in structure, for ease of maintenaince and change; Flushing pressure can be regulated, and can adapt to different filling environments; Filling can be rapidly, and flush efficiency is high.

Accompanying drawing 1 is the general flow chart according to full packages auto-flushing method of the present invention;
Accompanying drawing 2 is the schematic diagram of the preferred embodiment according to the fluid energy storage equipment used in full packages auto-flushing method of the present invention.
Reference numeral is as follows:
The 1-standpipe; The flat pipe of 2-; The large chamber of 3-; The 4-loculus; The large piston of 5-; The 6-valve piston; The 7-piston rod; The 8-sealing gasket; The 9-oil-in; The 10-oil-out.
The specific embodiment
Referring to accompanying drawing 1, the preferred embodiment that it has described a kind of full packages auto-flushing method comprises the following steps: at first configure the filling pipeline, be included in the filling pipeline standpipe peace pipe is set, the angle of the axis of standpipe peace pipe is 45～120 degree, is preferably substantially vertical; Between standpipe peace pipe, the fluid energy storage equipment is set, the fluid energy storage equipment is a hydraulic cylinder in the present embodiment; Rinse and for example, enter the fluid energy storage equipment with fluid (water) from standpipe, the fluid energy storage equipment can cut off the fluid communication between standpipe peace pipe, rinses and gathers in standpipe with fluid, and the pressure in standpipe is constantly increased; When the pressure in standpipe increases to a preset value (size of preset value can be adjusted by the setting of convection cell energy storage equipment), in standpipe, fluid pressure is opened the fluid energy storage equipment, so standpipe is communicated with flat pipe, with fluid, the pressure (higher than general flushing pressure) with described preset value enters in flat pipe in flushing in standpipe, is rinsed.
As shown in Figure 2, it has described a preferred embodiment of above-mentioned fluid energy storage equipment.It is a hydraulic cylinder, hydraulic cylinder has large chamber and loculus, standpipe is connected with the charging aperture of end, large chamber, and then be communicated with large chamber chamber, loculus is connected on the other end in large chamber, also there is discharging opening for connecting flat pipe on the chamber wall in large chamber, angle between the axis of charging aperture and the axis of discharging opening is 90 degree substantially, there is large piston in large chamber, there is valve piston in loculus, between large piston and valve piston, by piston rod, connect, be provided with Gask-O-Seal in loculus, it connects in the piston rod movable sealing, realize the seal isolation of large chamber chamber and loculus chamber, loculus has oil-in and oil-out, oil-in is connected with Hydraulic Station by check valve, oil-out is connected with fuel tank, be provided with overflow valve on the pipeline that oil-out is communicated with fuel tank, in use, the pressure medium of Hydraulic Station enters loculus by check valve, by oil-out, reflux, make in loculus to keep certain pressure, the pressure that pressure in standpipe is elevated to (namely in large chamber) in standpipe is greater than the certain multiple of little cavity pressure, while reaching preset value, piston rod moves, standpipe peace pipe is communicated with, the fluid of standpipe pours flat pipe with larger flow velocity and pressure, realize pressure washing.
The Area Ratio of large piston and valve piston is related to the size of flushing pressure, even the large cavity pressure that standpipe communicates in flat pipe equals the Area Ratio that little cavity pressure is multiplied by large piston and valve piston substantially, the pressure that generally can provide according to height and the Hydraulic Station of standpipe is according to required flushing pressure relative set, and preferably Area Ratio is 1.5～8.
