Abstract
The utility model relates to a negative-pressure material feeding circulation recovery type sand spraying machine, which comprises a high-pressure air source, a spray gun, a sand material cylinder, a filtering cylinder, a dust cylinder, a vacuum pump and a plurality of pipelines, valves. Through making use of the negative pressure that the high-pressure air can generate the internal expansion in the nozzle of the spray gun; the sand materials are sucked into the mixing chamber of the spray gun; then, through making use of the expanded high-velocity airflow, the sand materials are accelerated in the sand spraying pipe of the spray gun, and finally, the sand materials are sprayed onto the surface to be treated. Accordingly, the corrosion layer or the oxidation scale on the surface is removed; through the recovery of the vacuum pump and the filtering of the filtering cylinder, the sand materials can be used circularly, and simultaneously, the pollution of the dust to the environment can be avoided. Through adopting the negative-pressure feeding way, the stable and continuous feeding can be formed, and accordingly, the treating efficiency of the surface can be improved.
Description
The utility model relates to the improvement of sand-blasting machine, the metal surface processing machine.
Be used for rust cleaning, sand-blasting machine in the process of surface treatment process such as descale mainly contains two classes: a class is a non-circulating type, the sand material does not reclaim after the spray gun ejection, the result produces a large amount of dust, cause serious environmental to pollute, another kind of is the circulation recovery type, it utilizes vavuum pump with the sand material that sprays in the spray gun, air and the corrosion layer that gets off from processed removing surface, oxide skin reclaims together and separates, the sand material can repeatedly recycle, dust then is collected in the dust tube, avoided pollution, but, existing circulation recovery type sand-blasting machine is owing to adopting the malleation feed to have certain defective, at first, malleation feed mode feed instability, inefficiency, secondly, the malleation feed makes in the sand barrel and is in elevated pressures, and vavuum pump recovery sand material requires to be in negative pressure in the sand barrel, both are conflicting, in order to solve this contradiction, a kind of improved plan, as Chinese patent ZL93204845.5 " recovery type sand-blasting machine automatically circulates ", in the sand barrel, increase by one metallic sieve, play and isolate height, the effect in low-pressure chamber, but this sand-blasting machine can only be interrupted work, in order to supply with the sand material, it needs at set intervals the high pressure chest internal pressure to be dropped to low pressure, makes the sand material of falling on the screen cloth after the recovery drop to sand barrel bottom in the gravity effect.
The purpose of this utility model is to overcome the defective of above-mentioned prior art, proposes a kind of circulation recovery type sand-blasting machine of negative pressure feed, by improving the feed mode of existing circulation recovery type sand-blasting machine, improves the stability of feed.Realize continuous feeding, thereby improve the surface-treated operating efficiency.
The technical solution of the utility model is: by source of high pressure air, spray gun, the sand barrel, cartridge filter, dust tube, vavuum pump and plurality of conduits, the circulation recovery type sand-blasting machine of the negative pressure feed that valve is formed, expand into high velocity air in the nozzle of pressure-air in spray gun that source of high pressure air is supplied with, produce a certain size negative pressure simultaneously, utilize this negative pressure that the sand material in the sand barrel is drawn in the spray gun, the sand material that sucks enters blast tube after mixing with high velocity air together, in blast tube, the sand material is further quickened by high velocity air, be ejected into pending surface at last, sand material after the injection, dust is drawn back by vavuum pump with air, in the sand barrel, the sand material falls into tube bottom because of the gravity effect, and dust enters cartridge filter with air, fall in the dust tube after being filtered an inner filter core interception, air then is discharged in the atmospheric environment through vavuum pump.
The further technical scheme of the utility model is: sand barrel bottom is to the feeder sleeve between the spray gun, by inserting T shape three-way pipe joint, in feeder sleeve, introduce a certain amount of air, make the sand material be suspended state and enter spray gun, the air of introducing can pass through its flow of valve regulated, between sand barrel and three-way pipe joint, by valve control feed amount.
Technique effect of the present utility model is: because pressure-air expands in nozzle, form a certain size negative pressure on the one hand, thereby the sand material is drawn in the spray gun from the sand barrel, on the other hand, the high velocity air that forms that expands will enter the interior sand material acceleration of spray gun, make the sand material be ejected into processed surface with very high speed, thereby remove surface corrosion layer or oxide skin, sand material after the injection, dust are drawn back by vavuum pump with air stream, the sand material is got back to the sand barrel, can recycle repeatedly, dust is filtered and collects, and has avoided environmental pollution.
The further technique effect of the utility model is: the negative pressure that produces after directly utilizing pressure-air to expand is as feed power, and the air capacity by valve regulated feed amount and required introducing, can guarantee suitable gas, sand mixing ratio, thereby form stable, continuous feed improves surface-treated efficient.
