SU787679A1 - Nozzle for dust suppression - Google Patents

Description

one

The invention relates to mining and can be used to suppress dust during mining.

A nozzle for irrigating och-5 hog dust formations is known, including a housing nozzles for supplying water and air, a water chamber, a mixing chamber, a swirl chamber and a nozzle 1.

However, this nozzle is not adjustable to the desired range and shape of the spray plume.

The closest technical solution to the proposed one is the irrigator, which has a housing, a choke. 5 for supplying water, a steam supply nozzle and an adjusting screw for adjusting the droplet size 2.

A disadvantage of the known irrigator is that it does not regulate the pasHbie angles of the torch solution and does not have the ability to create an incomplete or eccentric ring body.

The purpose of the invention is the expansion of the range of adjustment of the parameters of the plume.

This is achieved by the fact that the means for adjusting the parameters of the irrigation plume is made in the form of two DLs installed perpendicular to each other.

to another adjustment screws, one of which is fixed in the housing, across the longitudinal axis of the housing, and the other is provided with an elastic tube and washer mounted on it and secured to move along the axis of the housing in the hole, which is made in the first adjustment screw.

FIG. 1 shows a nozzle for dust suppression, general view; Figure 2 is the same, front view.

The nozzle consists of a fitting 1 for supplying compressed air, which is a continuation of the housing 2, a fitting 3 under the ejected water, an adjusting screw 4 with a threaded bore, an elastic tube 5, a washer b, an adjusting screw 7, a nut 8 for locking the fitting.

The device works as follows.

Compressed air outlet

1 relates to the inner walls of the housing.

2, and ejects water from nozzle 3.) Air / water mixture, flow around adjusting screw 4, flexible 1st tube 5, washer 6 and head of adjusting screw 7, expire in the form of a conical flare

from dispersible liquid. The change of the flare of the flare is carried out by moving the adjusting screw 7 along the longitudinal axis of the body, i, which leads to a diametral increase in the elastic tube 5, and the washer is locked in the annular recess of the head of the adjusting screw 7, after passing through its conical surface tube. If it is necessary to create an incomplete or eccentric exit annular gap, the adjusting screw 7 is unscrewed from the hole of the adjusting screw 4, after which the latter is moved across the longitudinal axis of the housing to the required distance and the adjusting screw 7 is set. (Invention Dust suppression nozzle including body, liquid supply nozzle, compressed air supply nozzle and means for adjusting the parameters of the irrigation plume, characterized in that in order to extend the range of adjusting the parameters of the irrigation torch, the specified means for adjusting is made two adjusting screws perpendicular to each other, one of which is fixed in the housing across the longitudinal axis of the housing, and the other is fitted with an elastic tube mounted on it Oh and washer and fixed with the ability to move along the axis of the housing in the hole made in the first of these adjustment screws.
