Abstract
The utility model provides a steel pipe inner wall clearance grit blasting equipment, belongs to the clearance of large -diameter steel pipe production steel pipe inner wall firecoat in the metallurgical field, and including setting up the sandblast pipe in the steel pipe, the spray gun is connected to the one end of sandblast pipe in the steel pipe, and solenoid electric valve is located to the one end connection peening of sandblast pipe the steel pipe outside, still including setting up the gas blow pipe in the steel pipe, the gas blow pipe setting is in the below of sandblast pipe for steel pipe inner wall clearance grit blasting equipment, and the solenoid electric valve of gas blow pipe department is connected to the one end of gas blow pipe outside the steel pipe. The utility model discloses below at former steel pipe clean -up equipment sandblast pipeline increases a special gas blow pipe, and this root canal way flow is big, can light shot and the firecoat piled up bottom the steel pipe blow out the steel pipe. Through this two -way pipeline of solenoid valve switching, can descale and can clear up the shot in the steel pipe, improved production efficiency greatly.
Description
Technical field
The utility model belongs to the cleaning of field of metallurgy Large diameter steel pipe's production steel pipe inner wall firecoat.
Background technology
The method that inside and outside firecoat removed by traditional steel pipe is removed by pickling, pickling not only the health of workman can be worked the mischief, also serious pollution can be produced to the surrounding enviroment of factory, considerably increase the production cost of factory, therefore steel tube factory is all adopt bead to the de-scaling of steel pipe inside and outside wall mostly now.But original shot blasting equipment only has shot-peening one circuits, high pressure draught passes through spray gun, shot is ejected into steel pipe inner wall and removes firecoat, shot and firecoat are deposited in bottom steel pipe, the high pressure draught of spray gun ejection is not enough to the shot be deposited in steel pipe and firecoat blowout steel pipe, repeatedly just to can blow clean back and forth, greatly reduce production efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of steel pipe inner wall to clear up shot blasting equipment, the shot be deposited in steel pipe and firecoat can be blown out steel pipe.
The purpose of this utility model is achieved in that a kind of steel pipe inner wall cleaning shot blasting equipment, comprises the blast tube be arranged in steel pipe, and blast tube one end in steel pipe connects spray gun, and blast tube one end outside steel pipe connects shot-peening place solenoid electric valve; Described steel pipe inner wall cleaning shot blasting equipment also comprises the gas blow pipe be arranged in steel pipe, and gas blow pipe is arranged on the below of blast tube, and gas blow pipe one end outside steel pipe connects gas blow pipe place solenoid electric valve.
The utility model is by above design, (1) when ball blast, open shot-peening place solenoid electric valve, close air blowing pipeline place solenoid electric valve, high pressure draught enters spray gun injection shot by blast tube, and the effect playing cleaning steel pipe internal-surface firecoat at steel pipe internal-surface beaten by shot.(2) when blowing ball, closing shot-peening place solenoid electric valve, opening air blowing pipeline place solenoid electric valve, high pressure draught blows out steel pipe by air blowing pipeline the shot be deposited in steel pipe.
The utility model increases a special gas blow pipe in the below of raw steel pipe cleaning equipment sandblasting pipeline, and this root piping flow is large, can easily the shot be deposited in bottom steel pipe and firecoat blowout steel pipe.Switch this two roads pipeline by magnetic valve, de-scaling can clear up again shot in steel pipe, substantially increase production efficiency.
In order to aim at shot and firecoat better, one end downward bending of described gas blow pipe in steel pipe forms bend pipe.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, steel pipe inner wall cleaning shot blasting equipment, comprises and is arranged on blast tube 5 in steel pipe 4 and gas blow pipe 3, and blast tube 5 one end in steel pipe 4 connects spray gun 6, and blast tube 5 one end outside steel pipe 4 connects shot-peening place solenoid electric valve 1.Gas blow pipe 3 is arranged on the below of blast tube 5, and one end downward bending of gas blow pipe 3 in steel pipe 4 forms bend pipe 8, and the air outlet of bend pipe 8 aims at shot 7, and gas blow pipe 3 one end outside steel pipe 4 connects gas blow pipe place solenoid electric valve 2.
During steel pipe inner wall cleaning, when spray gun 6 retreats, shot-peening place solenoid electric valve 1 is opened, and gas blow pipe place solenoid electric valve 2 cuts out, and high pressure draught enters high-pressure spray gun 6 by blast tube 5 and ejects shot and carry out dephosphorization to steel pipe internal-surface.Now because nozzle spray eye is very little, high pressure draught pressure is very large, and flow velocity is fast, well can reach the effect of de-scaling, but blow the motionless shot 7 be deposited in bottom steel pipe.Cleaning end is when blowing shot, and spray gun 6 advances, and shot-peening place solenoid electric valve 1 cuts out, and gas blow pipe place solenoid electric valve 2 is opened, high pressure draught by gas blow pipe 3 to be deposited in steel pipe shot and firecoat blowout steel pipe.
Claims (2)
1. a steel pipe inner wall cleaning shot blasting equipment, is characterized in that: comprise the blast tube be arranged in steel pipe, and blast tube one end in steel pipe connects spray gun, and blast tube one end outside steel pipe connects shot-peening place solenoid electric valve; Described steel pipe inner wall cleaning shot blasting equipment also comprises the gas blow pipe be arranged in steel pipe, and gas blow pipe is arranged on the below of blast tube, and gas blow pipe one end outside steel pipe connects gas blow pipe place solenoid electric valve.
2. steel pipe inner wall cleaning shot blasting equipment according to claim 1, is characterized in that: one end downward bending of described gas blow pipe in steel pipe forms bend pipe.
