This sand-blasting machine course of work is as follows:
One, the set-up procedure before the work:
After connecting power supply and source of the gas, operating personnel hold sand-blasting gun 6 makes hairbrush 8 press close to the sand stockpile, presses and reclaims K switch 1, and magnetic valve E is open-minded, and air-flow enters negative pressure injector 1 by gas supply under constant pressure jar 13 and produces negative pressure.This negative pressure is through deduster 2, sweep-up pipe 3, sand tube 4, recovery tube 5, recycling cavity 7, the sand material constantly sucked in the middle storehouse of sand tube (storehouse umbrella crown 18 is at lowering position in this moment, and following storehouse umbrella crown 19 is in the jack-up position).Foreign material in the sand material and bigger sand grains can not pass through screen cloth 17, guarantee that mixer 11 is not blocked in the work.Dust in the sand material enters deduster 2 through sweep-up pipe 3, falls into the deduster bottom after the filtration.After sucking about 100 kilograms of sand material, close the recovery switch, reversal valve I commutation this moment, following storehouse umbrella crown 19 falls, and the sand material falls into down the storehouse, and preparation finishes.
Two, practical work process:
After connecting power supply and source of the gas, at first adjust pressure-reducing valve L, M, N, make three's force value coordinate coupling, operating personnel hold sand-blasting gun 6, make hairbrush 8 be close to surface of the work, press the recovery switch, and magnetic valve E is open-minded, and air-flow enters injector and produces negative pressure.Press sandblast K switch 2 after several seconds, this moment, sequence circuit was started working.At first clear up pipeline, magnetic valve F is open-minded, and air-flow enters mixer 11 and blast tube 10, residual long-pending sand in long-pending sand in the mixer 11 that bled by sand tube 4 and the blast tube 10 is cleared up away, in case blast tube 10 stops up.Sequence circuit enters the life's work state after several seconds, and magnetic valve B is open-minded, and following storehouse begins pressurization, and the sand material constantly enters in the mixer 11, and under the effect of sandblast air-flow, by blast tube 10 and blast nozzle 9, beats on surface of the work.The steel sand that rebounds together with remove from the metal surface foreign material such as the lacquer that gets off, rust by hairbrush 8 retainings in recycling cavity 7, and in recovery tube 5 enters sand tube 4.Dust wherein enters fiber bag precipitator 2 through sweep-up pipe 3, falls into deduster 2 bottoms after the filtration.After steel sand and other foreign material etc. filtered by screen cloth 17, steel sand temporarily dropped in the sand tube 4 in the storehouse.Treat down in the storehouse sand material ejection half back reversal valve H commutation approximately, middle storehouse umbrella crown 18 jack-up, in, go up the storehouse and isolate.Simultaneously magnetic valve A is open-minded, the pressurization of middle storehouse, and in treating, down after the pressure unanimity in storehouse, reversal valve I commutation, following storehouse umbrella crown 19 falls, and the sand of depositing in middle storehouse falls into down the storehouse, has realized the function of continuous circulation sandblast.After treating that knockout finishes, reversal valve I commutates once more, and following storehouse umbrella crown 19 is again by jack-up, and following, middle storehouse isolates.Magnetic valve A closes simultaneously, and middle storehouse stops pressurization, and magnetic valve C is open-minded, closes automatically behind the pressure of storehouse in laying down.Magnetic valve G is open-minded afterwards, goes up, middle storehouse communicates, and treats, closes automatically after the pressure unanimity of middle storehouse.Reversal valve H commutation simultaneously, storehouse umbrella crown 18 falls in making, and at this moment machine returns to the state of starting working again, has promptly finished one-time continuous periodic duty process.This process constantly repeats, and has realized not shutting down for a long time the function of continuous operation.After the nozzleman finishes, close sandblast K switch 2 earlier, begin to clear up pipeline this moment, and the course of work is as follows: magnetic valve B closes, and following storehouse stops pressurization, and magnetic valve D is open-minded simultaneously, unloads and falls down storehouse pressure.It is open-minded that magnetic valve F continues, and makes the air communication mistake, and cleaning is by 4 times storehouses of sand tube continue to bleed long-pending sand in the mixer 11.After treating down that storehouse pressure is unsnatched, magnetic valve F closes, and stops sand removal.At this moment close again and reclaim K switch 1, magnetic valve E closes, and stops to reclaim, and all work is finished.
Three, the maintenance after machine works finishes:
1. open sand tube 4 top covers, take out screen cloth 17, outwell foreign material, reinstall again.
2. pull down mixer 11, emit the steel sand (in order to using again) in the sand tube 4.
3. open deduster 2 bottom wickets, remove dust, shut then.
4. the cloth bag in the deduster 2 also will be cleared up or change to machine works after a period of time.
In the utility model, total source of the gas pipe 14 air demands are 6~10 meters 3/ minute, adjustable; Negative pressure injector 1 can produce 0.9~0.6 atmospheric pressure, and is adjustable; Maximum rust cleaning efficient is 20 meters 2/ hour, maximum 15 meters of the height that reclaim.This machine be a kind ofly can in the several work environment, eliminate rust, paint removal or the novel device that eliminates stress, under the control of sequence circuit, finish overall processes such as sandblast, recovery, dedusting and cleaning pipeline automatically.
