Technical solution of the present utility model is: it comprises frame, spray gun and the sandbox that is connected sand inlet tube and is connected with spray gun, spray gun is connected with source of the gas by air inlet pipe, described frame top is provided with track, track is provided with can be along the dolly of its slip, track one end is provided with the screw assembly by the belt wheel driven rotary, the other feeding motor that connects by conveyer belt with it that is provided with of screw assembly, the track other end is provided with the pipe fitting fixed mount, described spray gun front end is connected with the lance tube that the end is provided with spout by swivel joint, the spray gun rear end is fixed with screw mandrel, spray gun is fixed on the dolly, the screw mandrel of spray gun rear end is through in the screw assembly, the screw part of rotation screw assembly can promote spray gun by screw mandrel and slide along track, and dolly is provided with electric rotating machine and is connected by the swivel joint of conveyer belt with the spray gun front end, can drive the lance tube rotation.
Technique effect of the present utility model is: it has the low and good advantage of cleaning effect of simple in structure, cost, can be rapidly, efficiently, up hill and dale small diameter metal pipeline inwall is cleared up.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
The specific embodiment
As illustrated in fig. 1 and 2, it comprises frame 1, spray gun 2 and the sandbox 4 that is connected sand inlet tube 3 and is connected with spray gun 2, spray gun 2 is connected with source of the gas by air inlet pipe 5, described frame 1 top is provided with track 6, track 6 is provided with can be along the dolly 7 of its slip, track 6 one ends are provided with the screw assembly 8 by the belt wheel driven rotary, the screw assembly 8 other feeding motors 9 that connect by conveyer belt with it that are provided with, track 6 other ends are provided with pipe fitting fixed mount 10, described spray gun 2 front ends are connected with the lance tube 12 that the end is provided with spout by swivel joint 11, spray gun 2 rear ends are fixed with screw mandrel 13, spray gun 2 is fixed on the dolly 7, the screw mandrel 13 of spray gun 2 rear ends is through in the screw assembly 8, the screw part of rotation screw assembly 8 can promote spray gun 2 by screw mandrel 13 and slide along track 6, dolly 7 is provided with electric rotating machine 14 and is connected by the swivel joint 11 of conveyer belt with spray gun 2 front ends, can drive lance tube 12 rotations.
Described sandbox 4 is fixed on frame 1 bottom, and frame 1 is provided with collection box 15 in an end that is provided with pipe fitting fixed mount 10, the sand and dust of spray gun 2 ejections can be reclaimed after processing pipe fitting, and collection box 15 is connected with sandbox 4 by sand returning pipe 17.
Described collection box 15 is provided with deduster 16.
Described sand returning pipe 17 is provided with vibrating motor 18.
Described frame 1 is provided with holder for screw rod 19 in an end that is provided with screw assembly 8.
The end of described lance tube 12 is provided with can be along the idler pulley 20 of workpiece tube wall rotation.
The energy that the utility model mainly utilizes sandblast to produce impacts the rust staining, oxide skin, greasy dirt of metal pipe internal wall etc., thereby reaches the purpose of cleaning.Simultaneously, set up very important basic graphic (being common so-called hair side) at surface of the work, and can by the varigrained abrasive material of transposing, reach roughness in various degree, greatly improve the adhesion of metal pipe internal wall and coating, plating material, make bond bonding more firm.
The utility model compressed air be feed power be again the acceleration power of jet.Employing compressed air is power, to form the high velocity jet bundle with material spray (copper ore, quartz sand, diamond dust, iron sand, sea sand) high velocity jet is to being needed to process the metal pipe internal wall surface, the shape on metal pipe internal wall surface is changed, because abrasive material is to impact and the shear action on metal pipe internal wall surface, make the surface of metal pipe internal wall obtain certain cleannes and different roughness, the mechanical performance on metal pipe internal wall surface is improved, therefore improved the fatigue resistance of metallic conduit, increased the adhesive force between it and the coating, prolong the durability of filming, also be conducive to levelling and the decoration of coating.The innovation derusting process that this patent proposes is thorough, the most general, the rapidest, the most most effective method for cleaning.Can between different roughness, select arbitrarily, and other technique can not realize this point.
