Abstract

The utility model relates to a combined wet abrasive blasting nozzle which is a subassembly used for a sand-blower. The utility model is mainly composed of a sand-blasting hose, a sand-blasting blast nozzle, a water-adding device, etc., which are connected with each other. The device has the advantages of effective pollution prevention, and low manufacture cost, and can be matched with various kinds of sand-blowers.

Description

Hybrid wet abrasive blasting mouth

The utility model is a kind of hybrid wet abrasive blasting mouth, and it is parts that are used on the sand-blasting machine.

At present, what the blast nozzle structure of sand-blasting machine was adopted is open work, and this kind structure is polluted big, and it not only brings harm to health, but also environment is polluted.In order to address the above problem, the foundation that has special sand blasting room, but operating personnel still are in the rugged environment and work, and build sand blasting room cost height, complex structure.

The purpose of this utility model has solved above-mentioned drawback, provides a kind of and has added the hybrid blast nozzle of water filling device in the blast nozzle internal water flooding or at it.

The purpose of this utility model is achieved in that it mainly is by sand blast hose, has the metallic sheath of internal thread, has the priming apparatus of annular water tank, blast nozzle, compositions such as water inlet pipe.Suit metallic sheath outside the close sand blast hose of blast nozzle section, the metallic sheath outer end is provided with the priming apparatus that water inlet pipe is communicated with the inner annular tank, enter sand blast hose simultaneously and mix ejection with sand, blast nozzle is connected with blast tube with connecting spacer shell, also can with the water injector design outside blast nozzle, directly spray water.

Its course of work: when the switch of fetching boiling water, water (press water) directly enters into the sand material that is about to ejection from the priming apparatus of annular water tank, makes the mixture of blast nozzle ejection sand, water, gas, thereby reaches the purpose of eliminating dust from flying.Maybe will design the priming apparatus outside blast nozzle, directly water spray mixes with water with the sand of blast nozzle ejection.

Advantage of the present utility model is: reasonable in design, simple, can reach the purpose of eliminating dust from flying, and can with the supporting use of polytype sand-blasting machine.

Description of drawings:

Fig. 1 is the utility model cross-sectional view.

Fig. 2 is the utility model one embodiment cross-sectional view.

Below in conjunction with drawings and Examples the utility model is done further and carefully to be stated:

As shown in FIG., near the outside suit

metallic sheath

2 and 2 of the sand blast hose 1 of 5 sections of blast nozzles ', metallic sheath 2 ' on water inlet pipe 7 is housed and is communicated with the annular water tank priming apparatus 3 that is located at metallic sheath 2 ' inside, be connected with sand blast hose in it 1, perhaps outside blast nozzle 5, directly make water injector 3 ', its water spout is 8 shapes of twitching one's mouth, the water that makes ejection is the vaporific of covering of the fan.

Claims

1, a kind of hybrid wet abrasive blasting mouth, it mainly is by sand blast hose 1, screwed metallic sheath 2,2 ', the priming apparatus 3 that has annular water tank, connect spacer shell 4, blast nozzle 5 and water inlet pipe 7 are formed, it is characterized in that: near the outside suit metallic sheath 2 and 2 of the sand blast hose 1 of 5 sections of blast nozzles ', metallic sheath 2 ' on water inlet pipe 7 is housed and is communicated with the annular water tank priming apparatus 3 that is located at metallic sheath 2 ' inside, communicate with sand blast hose in it 1, blast nozzle 5 usefulness connect spacer shell 4 and metallic sheath 2 ' interior sand blast hose 1 and are connected, perhaps outside blast nozzle 5, directly make water injector 3 ', its water spout is 8 shapes of twitching one's mouth.
