Abstract
The utility model which discloses an abrasive water efflux nozzle is used for cleaning and cutting. The utility model is characterized in that the water nozzle of the utility model is provided with a group of eyelet holes; the eyelet holes which are evenly distributed are not aggregated, and are provided with the slope angles. A strand of efflux which is not aggregated is formed, when the high pressure water flows into the cavity of the nozzle, and the negative-pressure is generated; the abrasive material sucked into the cavity is mixed with the water, and is used as the working media. The width in each cleaning and cutting process can be increased by the method. The utility model has the advantages of high work efficiency, long service life and simple structure; at the same time, the abrasion of the inner wall of the nozzle is reduced, the self suction type feeding method for the abrasive material is adopted, and the utility model which can be applied to any cleaning occasion can be applied to the deep-groove cutting which is difficult to process at present.
Description
The utility model relates to a kind of high-pressure water jet abrasive material cleaning equipment, especially is applicable to the cleaning of coal, metallurgy and construction sector and the deep trouth cutting of hard material.
In prior art, be used for cutting or surface-treated abrasive waterjet nozzle, be widely used in the world in recent years, for example U.S. Pat 4,080,762 abrasive nozzle and US4,412, the launching technique of 402 pairs of gas abrasive materials and equipment, and EPO110529 high speed abrasive jet etc., its structure or principle mainly are: the multiply water jet is in the hole of arranging in garden week by rule from (operating) water nozzle and ejects, and produces negative pressure by effect in Du of river in Shangdong Province, suction dry type abrasive material, and in spray chamber, mix with water, form the abrasive water-jet slurry then and spray from abrasive jet, the major defect of this structure is that the shower nozzle inwall produces the severe pitting wearing and tearing, influences service life.Existing (operating) water nozzle makes the tapered ejection of water jet, each strand jet converges in a bit, must cause collision and interference mutually between each strand jet like this, cause very macro-energy loss, correspondingly service efficiency is also low, and when especially being applied to the mesolow cleaning, it is too concentrated that jet hits the range of stress, correspondingly each cleaning area is little, and operating efficiency is not high.
The utility model is developed a kind of high efficiency abrasive jetting shower nozzle in order to overcome above-mentioned weak point, its main feature is the improvement on the nozzle arrangements, (operating) water nozzle of the present utility model adopts and does not converge and with one group of aperture homogeneous texture form at inclination angle, reduce energy loss, control abrasive jet length simultaneously, and outlet diameter, make its diameter greater than the diameter of abradant jet by the exit, to reduce the shower nozzle inner wall abrasion, improve service life.Make reaching under the prerequisite of cleaning instructions for use, make and effectively hit the area increase each time, thereby improved cleaning efficiency.
Description of drawings:
Accompanying drawing 2 is B-B profiles of abradant jet shower nozzle.
Accompanying drawing 3 is how much motion diagrams of (operating) water nozzle work of abradant jet shower nozzle.
Below in conjunction with accompanying drawing the utility model is described in detail, accompanying drawing 1 expression abradant jet shower nozzle is made up of housing (1), (operating) water nozzle (2), abrasive jet (3) end cap (4), high-pressure water pipe (5), abrasive material inlet tube (6) and O RunddichtringO etc.The operation principle of this shower nozzle is that water under high pressure enters nozzle cavity through high-pressure water pipe (5), by one group of aperture in the (operating) water nozzle (2), enter hybrid chamber (7) with certain pressure, cause negative pressure, utilize this negative pressure mixing with water under high pressure in the dry type abrasive material inspiration hybrid chamber (7) that places abrasive material inlet tube (6), form the usefulness of defibrination for cleaning or cutting work.
The main feature of this shower nozzle is that (operating) water nozzle (2) makes the hollow garden of stairstepping post, be uniform-distribution with one group of small garden hole in outer rim boss upper edge, its underpart garden week, these holes are with respect to the certain angle of (operating) water nozzle axis inclination, and the extended line of each little centerline hole and (operating) water nozzle axis are non-intersect, each does not converge mutually, being single leaf hyperbola distributes, the small garden hole diameter is φ 0.9～2mm, it communicates with the water under high pressure tube chamber, small garden hole center line and the vertical guide angle of crossing the (operating) water nozzle axis are α=5 °～20 °, and (operating) water nozzle (2) is made with casting brass.It is the garden cylindricality that abrasive jet (3) is made profile, and endoporus is taper, and abrasive jet (3) is made with No. 45 steel, the inner surface sprayed wc.Housing (1) is made for shaped steel or steel-casting, end cap (4) is made with shaped steel, it with housing between with being threaded, so that push down abrasive jet (3), simultaneously with this fixedly (operating) water nozzle (2) and the relative position of abrasive material inlet tube (6) in housing, porosely on the end cap face communicate with abrasive jet.Between high-pressure water pipe (5) and housing for being threaded.It is made with No. 20 steel or seamless steel pipe.
How much moving pictures of (operating) water nozzle (2) work as shown in Figure 3, C represents (operating) water nozzle small garden hole water inlet joint garden D
1, F represents the minimum cross section joint garden that water jet shrinks---hyp trifle garden (larynx garden) D of single leaf
2, E represents water jet outlet joint garden D
3, and the main effect of abrasive jet (3) is to produce negative pressure, in order to reduce abrasion, should control abrasive jet length L ' and outlet diameter D
3' size, make L '=0.8～1.2L, L is water jet minimum of contraction cross section to the length of (operating) water nozzle water inlet, its outlet diameter D
3' greater than the diameter D of abradant jet by the exit
3So, almost can ignore the wearing and tearing of abrasive jet inner chamber, this is outstanding characteristics of the present utility model.
The utility model compared with prior art has following advantages:
1. the (operating) water nozzle of this structure increases cutting and cleaning width, can increase work efficiency about 50%;
2. the interference reduction between each strand jet and the abrasive material simultaneously, thus the wearing and tearing of shower nozzle inwall reduced, improved service life;
Adopt simple self-priming abrasive material feed mode, it can be widely used in various cleaning occasions, and the deep trouth that can also be used for simultaneously still being difficult at present carry out cuts.
Claims (4)
