Penetrate the easily caking material such as sodium bicarbonate.
Background technology
Existing sand-blasting machine is divided into suction-type and forced two kinds, can be used for cleaning removing object with sand-blasting machine injection sodium bicarbonate
The coating on surface, rust deposite, dirty without damaging base material, but sodium bicarbonate (sodium acid carbonate) hygroscopic caking, poor fluidity is frangible,
Cause there are many defects with both sand-blasting machines injection sodium bicarbonate.
Material is sucked blast tube, thing by the negative pressure that suction-type sand-blasting machine is produced using compressed air high-speed motion in spray gun
Material is directly connected with air, because of the moisture caking in sodium bicarbonate absorption air pipeline and nozzle can be made stifled for spraying sodium bicarbonate
Plug, causes continuously, uniformly to spray, causes inefficiency.
Forced sand-blasting machine can utilize drying compressed air, it is to avoid sodium bicarbonate water suction caking plug nozzle, but sodium bicarbonate exists
When flowing to blast tube by sand valve under pressure inside the tank driving, sodium bicarbonate can be crushed compacting, and damming is formed before valve port, cause small
Soda conveying has some setbacks, and flow control is inaccurate, and when especially requiring low discharge, sodium bicarbonate often blocks valve port, it is impossible to effective quilt
Conveying.In order to continuously produce, artificially sand valve have to be opened greatly, so as to cause the waste of sodium bicarbonate, increase use cost.
In view of this, it would be highly desirable to invent it is a kind of can continuously, uniform and flow can accurate adjustment the spray for being used to spray sodium bicarbonate
Sand machine.
