Background technique
Sand-blasting gun is the common tool of machinery field, is extensively used in the big of the industries such as ship, chemical industry, water conservancy, machinery
In the treatment process such as type equipment, the surface sand-blasting of various machine workpieces and daily necessities, derusting, decontamination.But existing skill
There is deficiency below mostly in the sand-blasting gun in art:
1, sand-blasting gun nozzle wear is uneven, nozzle lower end serious wear, uses the later period in blast nozzle, sand deviates base tube
The increasing proportion of axis area, sandblasting efficiency reduce；
2, spray gun vulnerable part replacement trouble, after gaseous core abrasion, sand rifle is replaced after needing integral demounting；
3, it is difficult to the recycling that commutates after gaseous core abrasion, since the gentle seat of gaseous core is to be threadedly coupled, position is substantially solid after fastening
It is fixed, after nose wear, it is difficult to which gyrobearing continues to use again.
Summary of the invention
The utility model provides a kind of efficient sandblasting of metal tube surface treatment for above-mentioned the deficiencies in the prior art
Rifle.
The utility model a kind of metal tube surface treatment efficient sand-blasting gun, by nozzle, gun body, high speed gas jet stream
Pipe and sand suction pipe combination are constituted, and inner duct is that funnelform nozzle is fastened and connected by pressure cap by the front end of tubular gun body, gun body
Rear end covered by gaseous core and connect with jet pipe sealed rigid, have the sand suction pipe for cutting gun body inner cavity in the side wall of gun body.
Its nozzle and gun body and the bore of jet pipe are same axis as a further improvement of the utility model,.
Jet pipe enters in gun body and constitutes in gun body between the inner wall of gun body as a further improvement of the utility model,
Chamber, incision end to the gun body inner cavity of sand suction pipe.
The funnel-form inner cavity flared end of nozzle and gun body inner cavity are isometrical company as a further improvement of the utility model,
It connects, its funnel cervical part of esophagus is opposite undergauge jet nozzle.
The outer wall of gun body has the limit branch fixed by angle adjustment bolt as a further improvement of the utility model,
Seat, limit support are mutually fixed by lateral adjustments bolt with connecting plate, and connecting plate passes through vertical adjustment bolt and sandblasting cabinet steel
Frame is mutually fixed.
It is opposite with sand suction pipe on the bell-mouthed inner wall in funnel-form inner cavity of nozzle as a further improvement of the utility model,
Position is answered to be equipped with the sub-sand block of protrusion.
The jet pipe housing annular sealing ring of the high speed gas and gun body are tight as a further improvement of the utility model,
Close fit.
A kind of efficient sand-blasting gun of the metal tube surface treatment of the utility model, it is easy for installation, it more finishes changing nozzle and penetrates
Air inlet seat is inserted into after flow tube, then locking positioning wrench and jet pipe sealing gland；Vulnerable part is readily replaceable, nozzle
After jet stream pipe abrasion, unclamps positioning wrench and jet pipe sealing gland is i.e. Ke Kuaisugenghuan；Jet pipe long service life, jet stream
It after pipe meets sand surface wear, can be continued to use after rotating by a certain angle, one times or more, while sand material at least can be improved in jet stream tube lifetime
Scatter small, sand material utilization rate height.
Detailed description of the invention
Fig. 1, Fig. 2 are the structural schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing to a kind of efficient sand-blasting gun of metal tube surface treatment of the utility model, make furtherly
It is bright:
As shown in Figs. 1-2, the efficient sand-blasting gun of a kind of metal tube surface treatment of the utility model, by nozzle 1, gun body
2, the jet pipe 3 of high speed gas and the combination of sand suction pipe 4 are constituted, and inner duct is funnelform spray by pressure cap 5 by the front end of tubular gun body 2
Mouth 1 is fastened and connected, and the rear end of gun body 2 is connect by gaseous core capping 6 with 3 sealed rigid of jet pipe, outside the jet pipe 3 of high speed gas
It is cased with annular sealing ring 15 and gun body 2 is fitted close, gaseous core capping 6 compresses the sealing of 15 realization device of annular sealing ring.In gun body 2
Side wall have incision gun body inner cavity 7 sand suction pipe 4.Nozzle 1 and gun body 2 and the bore of jet pipe 3 are same axis.In jet stream
Pipe 3 enters constitutes gun body inner cavity 7, incision end to the gun body inner cavity 7 of sand suction pipe 4 between the inner wall of gun body 2 in gun body 2.Nozzle 1
Funnel-form inner cavity flared end and gun body inner cavity 7 is isometrical connection, its funnel cervical part of esophagus is opposite undergauge jet nozzle.Gun body 2
Outer wall have the limit support 9 fixed by angle adjustment bolt 8, limit support 9 passes through lateral adjustments bolt 10 and connecting plate
11 phases are fixed, and connecting plate 11 is fixed by vertical adjustment bolt 12 and 13 phase of sandblasting cabinet steelframe.In the entrance of funnel-form nozzle 1
Channel wall is equipped with the sub-sand block 14 of protrusion, and sub-sand block 14 is corresponding with the entrance of sand suction pipe 4, since the sub-sand of sub-sand fast 14 is made
With making sand grains majority be diverted to the two sides of sand mouth, sand grains increases through nozzle side surface current amount, reduces the abrasion of nozzle lower end, makes
The sand grains of jet gun mouth is distributed in base tube axis area increasing proportion, reduces dispersing for sand grains, so that base tube be made to be increased by sand coarse aggregate ratio
Add, improves sandblasting efficiency.
Compressed air is sprayed through jet pipe, into after nozzle, generates negative pressure near jet pipe front end, and negative pressure is by sand suction pipe
In sand grains inlet nozzle, sand grains under the action of sub-sand block, to nozzle both sides dispersion simultaneously and compressed air mix, compressing
Under the drive of air, accelerating to spray to base tube surface, impact force removes base tube surface film oxide, meanwhile, by its surface texturing, it is
Spraying provides satisfactory surface.
