Abstract
The utility model discloses air-pressure dustless sand blasting equipment used for processing the surfaces of workpieces, which comprises a compressed air source 1 and a spray gun 2. The utility model is characterized in that a front input port 4 of the spray gun 2 is connected with a water and sand stirrer 5, the water and sand stirrer 5 is composed of a cylinder body 11, an impeller 6 for stir, a motor 7 and a nozzle 8 for stir, and the nozzle 8 for stir is connected with the compressed air source 1 via a valve 10. The utility model can be widely used for the occasions needing to process the surfaces of workpieces, such as derusting, welding slag removal, glass pattern spray, etc. The pneumatic dustless sand blasting equipment has the advantages of simple structure, easy operation, convenient outgoing work and high surface treating capability without dust pollution.
Description
The utility model relates to a kind of abrasive blast equipment that surface of the work is handled, especially a kind of air pressure dust-free blasting equipment of being used for.
Existing abrasive blast equipment has two types: a class is to be the air pressure abrasive blast equipment of major impetus with air pressure, and another kind of is to be the hydraulic pressure abrasive blast equipment of major impetus with hydraulic pressure.The air pressure abrasive blast equipment is to export compressed air with compressed air source, carry out being ejected on the surface of the work after sand gas mixes through spray gun then, this abrasive blast equipment has simple in structure, spray speed is high, the advantage that the surface treatment ability is strong, but its work the time can produce a large amount of dust pollutions, and the operator sucks excessive dust easily and health is worked the mischief, also will influence the sight line that the operator observes workpiece working position and state owing to dust from flying simultaneously, and then influence is to the crudy of workpiece.Although some air pressure abrasive blast equipments cooperate vacuum cleaning plant together to use at present, also just on the degree of dust pollution, alleviate to some extent.And the hydraulic pressure sand-blasting machine adopts to the major impetus of liquid pressurization back as sandblast, does not produce dust pollution during its work, but since liquid to add the efficient of pressure ratio air compression low, thereby it is low and cause a little less than the surface treatment ability to spray the spray speed of thing.
The purpose of this utility model provides a kind of air pressure dust-free blasting equipment that surface of the work is handled that is used for, and does not produce dust pollution during work, and the spray speed of spraying thing is high, and the surface treatment ability is strong.
The utility model realizes that in following mode it comprises compressed air source and spray gun, and compressed air source links to each other with the back input port of spray gun, and the preceding input port of spray gun is mixed device with water sand and linked to each other.Water sand is mixed device can be by cylindrical shell, mix impeller, motor and mix nozzle and form, and mixes impeller and links to each other with motor, mixes nozzle and links to each other with compressed air source through a valve.Compressed air source output compressed air during work, be transported to the injection power of spray gun as spray gun, water sand mixes device Jiang Shui and sand mixes after water sand is mixed the preceding input port that the outlet of device is transported to spray gun, compressed air causes high velocity air in spray gun, make formation turbulent region in spray gun and produce negative pressure, this negative pressure sucks the water sand mixture in the preceding input port of spray gun in the spray gun, and the water sand mixture mixes the back high velocity jet again and goes out with compressed air.Because what eject is the mixture of water, sand, gas, thereby acts on the surface of the work and can not produce dust pollution.Water sand is mixed device three kinds of working methods: first kind is that Motor Drive is mixed the impeller rotation, and Jiang Shui and sand are mixed, and valve is in closed condition, mixes nozzle not work; Second kind is that motor is not worked, and valve is in open mode, and compressed air source transfers out compressed air and through mixing the nozzle ejection water and sand mixed; The third is motor work, and valve is also opened, and mixes impeller and mixes nozzle and simultaneously water and sand are mixed.Can select water sand to mix the working method of device according to the ratio of water and sand and the granular size of sand during work.Under the extraneous circumstance that does not have the Motor Drive power supply, still can adopt second kind of working method work.
For the mixture of anti-sealing, sand, gas sputtering phenomenon occurs after being ejected on the surface of the work, can adorn an anti-sputter cover at the front end of spray gun.
The utlity model has simple in structure, volume is little, in light weight, be convenient to the operation of going out, easy to implement, no dust pollution during work, the surface treatment ability is strong, do not influence advantages such as operator's sight line, can be widely used in eliminating rust, remove welding slag, remove old paint and glass, in the spraying decoration artistic carving of hard material surfaces such as sheet metal, marble slab.
Below with reference to accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
With reference to Fig. 1, compressed air source 1 links to each other with the back input port 3 of spray gun 2, the outlet 10 that water sand is mixed device 5 links to each other with the preceding input port 4 of spray gun 2, water sand is mixed device 5 by tube 11, mix impeller 6, motor 7 and mix nozzle 8 and form, and link to each other with compressed air source 1 through valve 10, outlet 9 is arranged on the cylindrical shell 11, outlet 9 links to each other with the preceding input port 4 usefulness flexible pipes of spray gun 2, Jiang Shui and sand are put into cylindrical shell 11, compressed air sprays in the cylindrical shell 11 and mixes impeller 6 and driven by motor 7 and rotate by mixing nozzle 8 through valve, water and sand are mixed, and be transported to the preceding input port 4 of spray gun 2 by the outlet on the cylindrical shell 11 9, compressed air source 1 produces 8kg/cm
2The compressed air of pressure, the inside that is input to spray gun 2 produces negative pressure, this negative pressure sucks the water sand mixture in the preceding input port 4 of spray gun 2 12 in the spray gun 2, and water sand mixture 12 is mixed into the mixture of water, sand, gas again with compressed air in spray gun 2, eject through lance tube 13 then.In order to prevent sputtering phenomenon, anti-sputter dome 14 is housed on lance tube 12.
Claims (3)
1, a kind of air pressure dust-free blasting equipment, it comprises compressed air source 1 and spray gun 2, and compressed air source 1 links to each other with the back input port 3 of spray gun 2, and the preceding input port 4 that it is characterized in that spray gun 2 is mixed device 5 with water sand and is linked to each other.
2, according to the described air pressure dust-free blasting of claim 1 equipment, it is characterized in that water sand mix device 5 by cylindrical shell 11, mix impeller 6, motor 7 and mix nozzle 8 and form, mix impeller 6 and link to each other, mix nozzle 8 and link to each other with compressed air source 1 through valve 10 with motor 7.
3, air pressure dust-free blasting equipment according to claim 1 and 2 is characterized in that the front end of spray gun 2 is equipped with an anti-sputter cover 14.
