Abstract
The utility model provides a sand (shot) blasting machine with a wearproof spray nozzle and a rotary dust collecting bag. The utility model is characterized in that a high-pressure ring of an air curtain is arranged in a wearproof spray nozzle, sand (shot) stream jetted out can be effectively separated from a flaring cover of an air curtain by the ring of an air curtain, and the ring of an air curtain blows sand (shot) forwards at a high speed to spray the sand (shot) to workpieces. A rotary cloth bag installed in a dust removing chamber is coaxially connected with a pneumatic rotor. Under the action of the wind force of a suction blower, the pneumatic rotor automatically rotates to drive the cloth bag to fling dust and brush dust. The utility model has the advantages that the service life of the wearproof spray nozzle is long, the uniformity of the effects of shot blasting and sand blasting is good, and the dust removing cloth bag can be operated for a long time without blockage; gas exhausted out is clean and has no pollution to atmosphere, and the utility model has simple structure and multiple functions; the utility model is ideal selection for the technology which needs shot blasting treatment and sand blasting treatment.
Description
The utility model relates to a kind of sand-blasting machine, and sandblast (ball) machine of anti-wear shower nozzle and Rotary dust collecting bag particularly is installed, and the sand, the shot abrasive material that are suitable for different specific weight carry out surperficial abrasive blasting processing to various different hardness workpiece.
The shower nozzle of sand-blasting machine of the prior art, its nozzle are to have adopted high abrasion resisting materials such as tungsten carbide, boron carbide to make, involve great expense but service life only about 200 hours, the nozzle air consumption behind the abrasion deformation increases, sandblast deleterious, decrease in efficiency; The dust arrester of sand-blasting machine partly adopts fixedly bag-type dust in the prior art, cloth bag is very easily blocked by dust, influence dust removing effects, the Rapping apparatus of pair cloth bag and the disadvantage that inverse blowing device is blocked by dust with the change cloth bag were once arranged, but this two covering devices complexity, be awkward, effect is also unsatisfactory; The shower nozzle of sand-blasting machine of the prior art is by the negative-pressure sucking that air flow at high speed in the shower nozzle is produced sand to be sucked shower nozzle to mix the back ejection with air for sand, but the formed negative-pressure sucking of these shower nozzles is less, the shot that proportion is bigger just can not inhale in the shower nozzle, so can't use shot that the high rigidity metallic surface is carried out abrasive blasting.
The purpose of this utility model is intended to overcome the deficiencies in the prior art and a kind of abrasive blasting efficient height is provided, quality is good, the shower nozzle long service life, automatically dedusting is clog-free pollution-free and simple in structure, a tractor serves several purposes both can use sand also can use abrasive material such as shot that the different hardness workpiece is carried out the anti-wear shower nozzle of equipment that abrasive blasting handles and sandblast (ball) machine of Rotary dust collecting bag.
