Abstract

The utility model relates to a wet spray gun for the abrasive spraying equipment, comprising a tubular nozzle for compressed air and abrasive to pass and a mixing chamber thereof and a water atomizer for mixing gas and water, wherein, a water inlet pipe and a regulating valve thereof as well as an air inlet port and a regulating valve thereof are arranged on the water atomizer. When the wet spray gun sprays abrasive in a wet way, the dust pollution is eliminated, the spark produced by the dry abrasive spraying can be eliminated, and the environmental protection and the safety are greatly improved; the utility model can be used for spraying abrasive in a dry way and singly spraying water or compressing air; the utility model has the advantages of one gun with multiple purposes, wide applicability, easy regulation of the spraying bundle and high work efficiency.

Description

The wet type spray gun

The utility model relates to a kind of wet type spray gun of abrasive blast equipment, is applicable to that mainly the dry type abrasive blast equipment carries out wet abrasive blasting and handles.

In the prior art, the dry type abrasive blast equipment certainly leads to a large amount of workability dust when carrying out the sandblast operation.Its dust is often handled after collecting.Yet in a lot of work-yards, this work can't obtain implementing.Like this, must pollute, the application of dry type abrasive blast equipment is limited to environment.Chinese patent discloses for No. 94226182.8 a kind of " air pressure dust-free blasting equipment ", and it comprises compressed air source and spray gun.Mix device with water sand and link to each other at the place, preceding input port of its spray gun; Water sand mix device by cylindrical shell, mix impeller, motor and mix nozzle and form; Mixing nozzle links to each other with compressed gas source through valve.Its structure is complicated, and water, sand enter spray gun after mixing, and its jet beam state is difficult for regulating, and water, sand can not spray respectively.

The purpose of this utility model is to provide a kind of wet type spray gun that carries out dry type or wet blast operation, to overcome the deficiencies in the prior art.

Wet type spray gun according to this purpose design, comprise tubular nozzle that compressed air and abrasive material pass through and the hybrid chamber that links to each other of front end with it thereof, its architectural feature be also be provided with communicate with hybrid chamber, be used for the annular barrel water mist device that water mixes with gas, this device is provided with water inlet pipe and control valve and air admission hole and control valve thereof.Its course of work is: the mixture of compressed air and abrasive material ejects the abrasive material bundle after by tubular nozzle; The aqueous solution that is added with pressure enters hybrid chamber by the water inlet pipe control valve, with the wet type state ejection that is the water smoke parcel after abrasive material Shu Zaici mixes, thereby does not have the sandblast operation of dust disperse state.Its jet beam state can be regulated and be controlled by inflow control valve and air inflow control valve.

During this spray gun wet blast operation, not only eliminated dust pollution, also can eliminate, removed the dust work of treatment from, reduced production cost because the spark that the dry type sandblast produces all has greatly improved environmental protection and security.This spray gun still can be used for the dry type sandblast, and also injection water or compressed air are cleared up workpiece separately, the many usefulness of a rifle, and wide adaptability, and jet beam is easy to adjust, the work efficiency height.

Describe in detail below in conjunction with accompanying drawing embodiment:

Fig. 1 is the utility model one example structure schematic diagram;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

Referring to accompanying drawing, annular barrel water mist device 6 is fixed in tubular nozzle 2 one ends, and links to each other with hybrid chamber 7.Uniform 6 axial passages 4 on the annular barrel of water mist device 6, each Kong Yiduan communicates with atmosphere, and the other end communicates with hybrid chamber 7, and its air upstream end is established a rotatable back-up ring as air admission hole control valve 3, and the rotation back-up ring hides passage 4 can regulate air inflow.Also be provided with ring-type water-flowing trough 5 on the annular barrel of water mist device 6, this groove outside communicates with water inlet pipe and control valve 1 thereof, and the inboard radially communicates with each passage 4.
