Abstract

The utility model discloses a spray head for lowering dust. The spray head is added with a row of front spray orifices, back spray orifices are offset a portion of arc angle forward, a spray area is concentrated on the front space of the spray head, and the spray head for lowering dust makes up for the defect that the existing spray heads have spray dead angles. The utility model is suitable for mines, tunnels and other construction situations containing dense powder dust.

Description

Atomizing blow head for lowing dust

The utility model is specifically related to a kind of improved shower nozzle, particularly contains the depositing dust spraying nozzle that the bigger construction occasion of Dust Capacity is used to reduce dust content at mine, tunnel and other.

Existing a kind of depositing dust spraying nozzle, its main body is a hollow ball, is a nozzle at its front end, along row's spray orifice is arranged in 180 ° of scopes of last arc of the axial maximum outside diameter of spheroid.The spraying area that the spraying area that shower nozzle produced of this structure is scattered by a fan-shaped vertical spraying area and a level is formed, so just make a part of spraying area be positioned at the rear side of shower nozzle, make the place, angle far away of shower nozzle upside become the dead angle of spraying area simultaneously, thereby reduced the effect of depositing dust spraying, caused the waste of a part of aqueous vapor again.

The purpose of this utility model is the deficiency that will overcome existing shower nozzle technology, and a kind of rational in infrastructure, spraying nozzle that spray effect is good is provided.

The purpose of this utility model is finished as follows: the body of depositing dust spraying nozzle of the present utility model is a cylinder type hollow spheroid, front end at spheroid has a nozzle, two row's spray orifices before and after on the sphere of the spheroid front side first half, being drilled with, wherein the back spray orifice is to be offset row's aperture that one section arc angle is drilled to forward from the last arc of the axial maximum outside diameter of spheroid along sphere, and preceding spray orifice is one to arrange aperture on the sphere between back row's spray orifice and the nozzle.During practical application, the spraying area that this shower nozzle forms is to be composited by three spraying areas; Back spray orifice forms the fan-spray district of vertical tilt forward, and preceding spray orifice forms angle tiltedly far away spraying area, and nozzle forms the spraying area that level is scattered.

Depositing dust spraying nozzle of the present utility model is owing to increased preceding spray orifice, remedied the spraying space of angular region far away, sprayed in shower nozzle front side in the air owing to the back spray orifice being offset one section arc angle forward, the mist body being concentrated simultaneously, increase the mist volume density of spraying area, thereby improved dust-laying effect significantly.

Be further described below in conjunction with drawings and Examples.

Fig. 1 is the section of structure of the utility model embodiment.

Fig. 2 is the axial front view of the utility model embodiment.

See figures.1.and.2, the body of depositing dust spraying nozzle of the present utility model is a cylinder type hollow spheroid (5), and its afterbody has an air water import (6), and its front end is nozzle (1).Spheroid (5) and nozzle (1) all adopt cast member, and both are threaded in employing.On the sphere of spheroid (5) the front side first half, be drilled with back spray orifice (3) and preceding spray orifice (2), the number in hole does not have fixedly requirement, the arc angle of the axial maximum outside diameter of back spray orifice (3) offset ball (4) is chosen between 10～20 °, and the arc angle of the axial maximum outside diameter of preceding spray orifice (2) offset ball (4) is chosen between 30～50 °.Horn mouth is all made in the end of preceding spray orifice (2) and back spray orifice (3), and the mist body makes spraying area have mist volume density comparatively uniformly from angled the scattering in spray orifice ejection back.Fig. 1 dotted portion is represented the spraying area of nozzle (1), preceding spray orifice (2), back spray orifice (3) respectively, and as shown in the figure, the depositing dust zone of shower nozzle front side is effectively covered.

Claims

1, a kind of depositing dust spraying nozzle, this shower nozzle comprises the nozzle (1) of cylinder type hollow spheroid (5) and its front end, one row back spray orifice (3) is arranged on spheroid (5) upside sphere, it is characterized in that described back spray orifice (3) be offset forward from the last arc of the axial maximum outside diameter of spheroid (4) along sphere that one section arc angle is drilled to one arrange aperture, spray orifice (2) before also having one to arrange on the sphere between back spray orifice (3) and nozzle (1), preceding spray orifice (2) is distributed on the sphere of spheroid (5) the front side first half with back spray orifice (3).

2, shower nozzle according to claim 1, the arc angle that the axial maximum outside diameter of spray orifice (3) offset ball (4) is gone up arc after it is characterized in that is between 10～20 °, and the axial maximum outside diameter of preceding spray orifice (2) offset ball (4) is gone up the arc angle of arc between 30～50 °.

3, shower nozzle according to claim 1 and 2 is characterized in that preceding spray orifice (2) and spray orifice (3) end, back are bell mouth shape.
