Abstract
The utility model discloses a mine pre-mixed abrasive water-jet cutting device. The cutting device comprises a high-pressure water supplying device, a high-pressure abrasive tank, a mixing chamber, aspray gun and a bracket, wherein the high-pressure abrasive tank is connected between the high-pressure water supplying device and the mixing chamber through pipelines; the high-pressure water supplying device supplies high pressure water respectively for the high-pressure abrasive tank and the mixing chamber; the spray gun is connected on an outlet of the mixing chamber; and the bracket is fixedbelow the spray gun. By a pre-mixing way, the abrasive and the high pressure water form even suspending liquid in the high-pressure abrasive tank, then the suspending liquid is mixed and sprayed out together with the high pressure water in the mixing chamber from the spray gun, so as to form an abrasive particle flow-abrasive jet flow with extremely high speed to cut an object to be cut. The wholecutting device has fast cutting speed and obvious cutting effect and does not cause gas explosion due to no generation of sparks during cutting process; and the cutting device has no pollution and low cost and is specially used for the cutting in complicated environment under the mine.
Description
Technical field
The utility model belongs to the colliery technical field, particularly a kind of mining pre-mixed abrasive water jet cutter sweep.
Background technology
In the industry of colliery, tunnel exploitation, coal cutting roadway supporting etc. all can be cut rock, anchor pole.For example, in the driving of underground chamber, need be under the non-destructive situation of chamber country rock, to the geologic body scene in a certain zone wherein boring sample or rock core carries out geology and mechanical test analysis, because there are many dangerous gases in the down-hole, as methane, can not use the machine cuts mode of easy generation sparks such as electrogas welding to cut, and the space is narrow and small in the underground chamber, the cutting complicated condition, for satisfying the downhole production needs, the workman has to transport of materials to ground is cut, influence the continuity of underground work on the one hand, can expend a lot of times and great manpower on the other hand again, material resources are for the large-scale mine that requires modern production, its production cost improves greatly, so safety is badly in need of in the down-hole, practical on-mechanical cutting equipment.
At present, the water-jet technology development has been widely used in numerous areas such as mining, aviation, building, chemical industry, metallurgy, municipal works, weaving, Metal Cutting, broken rock and cleaning rapidly.Aspect cutting, the water jet cutting is that mode is cut in unique cold cut, avoided the thermal cutting process to be easy to generate spark, easily caused the shortcoming of gas explosion, how designing the water jet cutter sweep that uses under a kind of suitable mine just becomes problem to be solved in the utility model.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide that a kind of volume is little, cutting speed is fast, mining pre-mixed abrasive water jet cutter sweep safe in utilization, reliable.
The utility model is achieved through the following technical solutions:
Mining pre-mixed abrasive water jet cutter sweep, comprise high service device, high-pressure abrasive material jar, mixing chamber, spray gun and support, the high-pressure abrasive material jar is connected between high service device and the mixing chamber by pipeline, the high service device is respectively the high-pressure abrasive material jar and mixing chamber provides water under high pressure, spray gun is connected in the outlet of mixing chamber, and support is fixed on the spray gun below.
Described high service device comprises hydraulic pump, hydraulic motor and the high-pressure plunger pump that is linked in sequence, and the high-pressure plunger delivery side of pump is communicated with high-pressure abrasive material jar and mixing chamber respectively.
Described high-pressure abrasive material jar is provided with charging aperture and air bleeding valve, is connected with inlet valve on the charging aperture.
Described high-pressure abrasive material jar is communicated with the high-pressure plunger delivery side of pump respectively by the water inlet of top and bottom.
Be respectively equipped with choke valve and inlet valve on the connecting line between described mixing chamber and high service device and the high-pressure abrasive material jar.
Mining pre-mixed abrasive water jet cutter sweep described in the utility model, by preceding hybrid mode, abrasive material and water under high pressure are evenly mixed in the high-pressure abrasive material jar, form suspension by the road to mixing chamber, spray from spray gun with mixing chamber inner high voltage water, form abrasive particle stream-abradant jet with flank speed.Compare with the pure water jet, abradant jet is changed into abrasive particle stream to material high frequency bump and erosion effect with the pure water jet to the static pressure continuous action of material, and its action effect greatly takes on a new look.Before hybrid mode, abrasive material and water mixes, fully, the energy height of long, acquisition of abrasive particle acceleration time, more outstanding to the action effect of material is so its operating pressure can reduce greatly.Whole device no-spark in cutting process can not brought out gas explosion, and also has the depositing dust effect.Utilize high-pressure grinding material water jet that rock sample, rock core are cut, can realize the extraction of rock sample under the complex conditions; Anchor pole, anchor cable and hard top coal etc. are cut, safe and effective, guarantee carrying out smoothly of down-hole caving work.The diversity of its cutting can satisfy the requirement of various cutting work under the complicated environmental condition, saved a large amount of material resources manpowers, the medium that uses during cutting---water, cheap, the safety and sanitation of abrasive material can not bring environmental pollution, are highly suitable for cutting use in the complex environment under the mine.
