Description

The utility model relates to devices for spraying liquids and can be used in various industries, including to reduce dust in the mining industry.

Known flat-jet nozzle (AS No. 866232, class E21F 5/04, application No. 2740131, priority date 03/21/1979, published on 09/23/1981, State Design and Experimental Institute of Coal Engineering). A known flat-blast nozzle includes a body with an external thread for installing the nozzle in a dust suppression system assembly. An insert is installed in the housing opening having a groove for forming a flat torch. To fix the insert in the hole in the housing there is an annular bore into which the o-ring is inserted. The insert is mounted movably with the possibility of rotation around its axis.

The disadvantages of the known nozzle are the formation of the torch only due to the pressure of the water jet. High pressure is required in order to create a spray, and as a result, the inability to create a finely dispersed water spray.

The prototype is a well-known flat-jet nozzle (A.S. No. 900031, class E21F 5/04, application No. 2908342, priority date 04/09/1980, published 01/23/1982, Karaganda branch of the Eastern Research Institute for Work Safety in the mining industry). The known flat-jet nozzle comprises a housing, parallel water supply channels, a fluid plume forming channel connected to them, and a groove intersecting with the fluid plume forming channel. The groove is made with an arched convex bottom.

The main disadvantage of the known nozzle is the formation of a fluid plume only through the use of a water stream. The impossibility of the formation of the effect of water fog at the exit.

The technical result of the proposed utility model is to increase the angle of the flare and the range of irrigation.

A flat-nozzle nozzle containing a housing is proposed, in the housing there are channels for supplying pressurized water and an air mixture to a mixing chamber having a nozzle for discharging a water-air mixture.

The difference is that the housing consists of a nozzle and a shank arranged coaxially and fixed rigidly relative to each other, the mixing chamber expands towards the exit, the end part of the shank is in the form of a hemisphere, the air mixture is fed through the channels formed between the nozzle and the shank, the front part the nozzle has two concave, arc-shaped grooves arranged crosswise at an angle of 90 ° relative to each other, one on the outside of the front of the nozzle, the other on the inside of the front of the sample binders in the center of the nozzle diamond shape.

The essence of the utility model is illustrated in the drawings, where in FIG. 1 is a longitudinal section through a nozzle; FIG. 2 front view along section A-A.

In FIG. 1 jet marked 1, shank 2, mixing chamber 3, end part of shank 4, channels for air mixture 5, channel for water 6, notched concave shape 7, diamond-shaped nozzle 8.

The utility model works as follows. In the mixing chamber 3, channel 6 and channels 5 are supplied under pressure, respectively, water and air mixture. In the mixing chamber 3, the jets of water and air collide, the water stream is dispersed by the air stream, water droplets are broken into smaller ones by the air stream. The dispersed water-air mixture undergoes additional dispersion in the expandable part of the mixing chamber, and under the pressure at the outlet through the nozzle, a spray of water-air spray is formed. The use of air flow will allow you to create fine irrigation. Concave grooves 7 allow the formation of a flat torch at the exit. At the same time, the use of concave grooves 7 arranged crosswise relative to each other, at an angle of 90 °, one on the outside and the other on the inside of the front of the nozzle allows to increase the angle of the torch and make it flat.

The application of the proposed utility model will expand the operational capabilities of the nozzle, due to the range of the irrigation torch when creating a flat torch.
