Description

A kind of full packages automatic flushing device

Technical field

The utility model relates to a kind of device for filling, relates in particular to a kind of full packages automatic flushing device of filling pipeline.

Background technology

The mine filling is as a kind of processing method of goaf, and the application in mine is very extensive.In stowing operation, after mine is accomplished filling operation, need immediately pipeline to be washed, the purpose of flushing mainly is that the pipeline sediment in the flat pipe is cleaned out.At present, the developing technique flow process of paste body filling pipeline is: lotion---the spoil slurry---and coal ash pulp---water---wind, owing to do not have the energy storage equipment of water in the existing filling pipeline, when causing the water flushing; The impulse force that produces is smaller, receives the restriction of mine orographic condition simultaneously, when pipeline long; When knick point was many, this developing technique can not thoroughly be cleaned out the big spoil particle that segregation in the pipeline produces, and the time has been grown; Big spoil particle will bond on the inner-walls of duct, accumulates over a long period, and the internal diameter of pipeline will be more and more littler; Percent of pass finally causes line clogging worse and worse, causes whole filling pipeline thoroughly to be scrapped.

In the prior art, CN102072338A discloses a kind of blowoff valve that washes usefulness, 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 to be used for the mine filling, but is used among the oil drilling, and it can't realize high pressure washing equally.

The utility model content

For addressing the above problem, the utility model proposes a kind of filling and uses the full packages automatic flushing device, comprises standpipe, flat pipe and hydraulic cylinder; Said hydraulic cylinder has big chamber and loculus, and the internal diameter in big chamber is provided with big piston greater than the internal diameter of loculus in the big chamber; Be provided with valve piston in the loculus; Connect through piston rod between big piston and the valve piston, be provided with sealing gasket in the said loculus, said piston rod and said sealing gasket are realized the sealing between big chamber and the loculus; Said loculus is provided with oil-in and oil-out, and said oil-in is connected with Hydraulic Station through check valve, and said oil-out is connected with fuel tank, and the pipeline that said oil-out is communicated with fuel tank is provided with overflow valve; The end in said big chamber is provided with charging aperture, and said charging aperture is connected with standpipe, and the chamber wall in said big chamber is provided with discharging opening, and said discharging opening is connected with flat pipe.

The pressure relative set that the area beguine of wherein said big piston and said valve piston provides according to the height and the Hydraulic Station of standpipe.

The area ratio of wherein said big piston and said valve piston is 1.5～8.

The advantage of the utility model is: simple in structure, for ease of maintenaince and change; The flushing pressure scalable can adapt to different filling environment; Filling can be rapidly, and flush efficiency is high.

Description of drawings

Accompanying drawing 1 is the cutaway view according to the described full packages automatic flushing device of the utility model.

Reference numeral is following:

The 1-standpipe; The flat pipe of 2-; The big chamber of 3-; The 4-loculus; The 5-big piston; The 6-valve piston; The 7-piston rod; The 8-sealing gasket; The 9-oil-in; The 10-oil-out.

The specific embodiment

Shown in accompanying drawing 1, the full packages automatic flushing device is used in a kind of filling, comprises standpipe, flat pipe and hydraulic cylinder, and said hydraulic cylinder has big chamber and loculus; Standpipe is connected with the charging aperture of big end, chamber, and then is communicated with big chamber chamber, and loculus is connected on the other end in big chamber; On the chamber wall in big chamber, also have discharging opening and be used to connect flat pipe, the angle between the axis of charging aperture and the axis of discharging opening is 90 degree basically, has big piston in the big chamber; Have valve piston in the loculus, connect through piston rod between big piston and the valve piston, be provided with Gask-O-Seal in the loculus; It connects in the piston rod movable sealing, realizes the seal of big chamber chamber and loculus chamber, and loculus has oil-in and oil-out; Oil-in is connected with Hydraulic Station through check valve, and oil-out is connected with fuel tank, and the pipeline that oil-out is communicated with fuel tank is provided with overflow valve; In use, the pressure medium of Hydraulic Station gets into loculus through check valve, refluxes through oil-out; Make the certain pressure of maintenance in the loculus, when the pressure in the big chamber during greater than the certain multiple of little cavity pressure, piston rod moves; Standpipe peace pipe is communicated with, and the fluid of standpipe pours flat pipe with bigger flow velocity and pressure, realizes pressure washing.

The area of big piston and valve piston is than the size that is related to flushing pressure; Even standpipe equals the area ratio that little cavity pressure multiply by big piston and valve piston basically in the big cavity pressure that flat pipe communicates; The pressure that generally can provide according to the height and the Hydraulic Station of standpipe is according to required flushing pressure relative set, and preferred area ratio is 1.5～8.

The above; Be merely the preferable specific embodiment of the utility model patent; But the protection domain of the utility model patent is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model patent discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model patent.
