Abstract

The utility model relates to a special water spray nozzle for self-regulating pressure ore dressing, which comprises a spray nozzle and a pipe joint, wherein an arc-shaped baffle plate is arranged on the spray nozzle, a middle water pipe is arranged on the lower surface of the nozzle, the lower part of the outer wall of the middle water pipe is provided with a circular ring clamping groove, the middle part of the outer wall of the middle water pipe is provided with a clamping buckle which is buckled and connected with the clamping groove of the pipe joint, a tongue piece is arranged on the spray nozzle, the lower end of the tongue piece is movably connected with the spray nozzle, and the rear surface of the tongue piece is connected with the spray nozzle through a spring B. The utility model has the advantages that the utility model solves the blocking problem of the traditional coal washing water, the maintenance time can be reduced, the production efficiency can be increased, high pressure water is sprayed through the spray nozzle to form an even fan-shaped water curtain, the working area is large, the impact force is strong, the flushing effect is good, the utility model uses little water, the medium removing rate is high, and the cost is reduced. Under the condition of water pressure is reduced, the utility model still has a better operation effect.

Description

From the special-purpose water spout of pressure regulation ore dressing

(1) technical field: the utility model relates to a kind of water spout, the special-purpose water spout of particularly a kind of desliming de-mediated.

(2) background technology: the water spout that traditional domestic coal separation industry is used, normally drip with punching flowing water and sieve plate on the iron pipe.These traditional method results of use are undesirable, both seriously reduced the effect of desliming de-mediated, and influencing quality of cleaned coal greatly can not be up to standard; Waste water in a large number again and valuable medium raw material, obviously strengthened production cost; Also because of water pipeline often stops up, increase maintenance cost simultaneously, reduced production efficiency.

Application number be 02208407.X's " desliming de-mediated special-purpose water spout ", solved the defective of above conventional method effectively, have advantages such as water saving, easy-maintaining, coal washing be effective, but under the situation that hydraulic pressure reduces, result of use can descend to some extent then.

(3) summary of the invention: but the purpose of this utility model is to provide a kind of desliming de-mediated, does not stop up, water saving, efficient height, still have the water spout of better result of use under the variation in water pressure situation.

The purpose of this utility model realizes by following scheme: from the special-purpose water spout of pressure regulation ore dressing, mainly comprise nozzle and pipe joint, delivery port peripheral hardware one curved baffle on nozzle top, water pipe in the middle of the bottom is provided with, middle pipe outer wall is provided with " O " shape groove, on " O " type groove round section joint ring is set, and cooperates with the pipe joint inner wall sealing, the nozzle middle part is provided with buckle, is connected with the draw-in groove on pipe joint top; The water inlet of pipe joint bottom is provided with screw thread outward, is connected with the running water water pipe, is characterized in: establish a tongue piece on nozzle, tongue piece lower end and nozzle flexibly connect, and the tongue piece back is connected with nozzle by spring B.

Place spring A in described pipe joint inwall and the middle pipe outer wall gap, spring A upper support face is the draw-in groove of pipe joint, and the lower support face is a pipe joint lower lumen face, can make buckle and draw-in groove card jail.

The tongue tip is established in described tongue piece lower end, and the tongue tip can insert in the tip hole that is located on the nozzle, thereby is movably connected on nozzle.

The utlity model has following advantage: 1, solved the blockage problem of traditional coal washing water, in case of stopping up, nozzle and pipe joint have been turned on mediation get final product, thereby reduced maintenance time, improved production efficiency; 2, fundamentally satisfied the requirement of coal washing sieve plate water, water under high pressure directly sprays through nozzle, forms fan-shaped water curtain and evenly sprays to coal cinder on the sieve plate, and the work area of formation is big, and impulsive force is strong, and it is wide to spray the sieve plate area, and developing result is good; 3, with respect to traditional coal washing method, water is few, and de-mediated rate height can make mud and medium (iron powder) on the coal cinder rinse well, reduces production costs; 4, because the effect of tongue piece still has better result of use under hydraulic pressure reduction situation.

(4) description of drawings: Fig. 1 is the utility model package assembly schematic diagram; Fig. 2 decomposes side cutaway view for the utility model; Fig. 3 the utility model decomposition elevation.

In the accompanying drawing: 1, nozzle; 2, pipe joint; 3, delivery port; 4, baffle plate; 5, middle water pipe; 6, " O " type groove; 7, " O " type circle; 8, buckle; 9, draw-in groove; 10, spring A; 11, water inlet; 12, screw thread; 13, tongue piece; 14, the tongue tip; 15, tip hole; 16, spring B; 17 corner angle A; 18 corner angle B.

(5) specific embodiment:

Below in conjunction with embodiment utility model is further described: as Fig. 1～shown in Figure 5, from the special-purpose water spout of pressure regulation ore dressing, mainly comprise nozzle (1) and pipe joint (2), the delivery port on nozzle top (3) is outer to be a curved baffle (4), make of the effect of the water of ejection through curved baffle, the water curtain that becomes band, thus working face increased; Water pipe (5) in the middle of the bottom of nozzle is provided with, middle pipe outer wall bottom is provided with " O " type groove (6), on " O " type groove round section joint ring (7) is set, and cooperates with the pipe joint inner wall sealing, avoids leaking; The nozzle middle part is provided with buckle (8), be connected with the draw-in groove that is located at pipe joint top (9) clinching, place spring A (10) in pipe joint inwall and the middle pipe outer wall gap, spring A upper support face is the draw-in groove of pipe joint, and the lower support face is the inner cavity surface of pipe joint bottom, when desire is connected nozzle with pipe joint, pipe joint can be put in the bottom of nozzle, holddown spring A afterwards, half-twist can make buckle and draw-in groove card jail again; The water inlet of pipe joint bottom (11) is outer to be provided with screw thread (12), is connected with the running water water pipe; Establish a tongue piece (13) on nozzle, the tongue tip (14) is established in the tongue piece lower end, and the tongue tip can insert in the tip hole (15) that is located on the nozzle, thereby is movably connected on nozzle; The back of tongue piece is connected with nozzle by spring B (16), with the elastic force of spring B tongue piece and baffle plate is close to, and when discharge pressure reached design pressure, tongue piece reached the effect of automatic adjustment hydraulic pressure with the automatic hypertonic of the pressure of water.

Spring B also can adopt pull-type, and an end that is about to spring B is fixed in tongue piece front (promptly with the baffle plate contact-making surface), and the other end is fixed on the nozzle or on the baffle plate.

For the ease of loading and unloading, on the baffle plate of nozzle, be provided with corner angle A (17), on pipe joint, be provided with corner angle B (18).
