Abstract
The utility model discloses a steel tube descaler, which comprises a descaling tank body, wherein an inlet and an outlet which are penetrated by a steel tube, and a high pressure water descaling ring for descaling the steel tube are arranged on the descaling tank body; a gas blowout water retaining ring is arranged in a cavity of the descaling tank body and is close to the inlet; a central axis of the gas blowout water retaining ring coincides with a central axis of the inlet of the descaling tank body; and air nozzles for preventing high pressure water and scales from splattering are uniformly arranged on the gas blowout water retaining ring. Each air nozzle faces to a steel tube operation track and deflects by 15 degrees towards the direction of the outlet. The water retaining device adopts compressed air and reverse blowing-sweeping instead of high pressure water reverse spraying. Iron chains are used for blocking coarse scales, and air sprayed at high speed is blown reversely to cut off high pressure water splattering outwards and flowing out along the steel tube, so that the water retaining effect is consistent with the high pressure water reverse blowing effect, the water consumption is reduced, the water is saved, and the energy consumption is low; and simultaneously, the temperature drop of steel tube descaling is smaller, and the influence on steel tube rolling is reduced.
Description
Technical field
The utility model relates to the steel pipe descaling device on the steel sheet production line, especially a kind of steel pipe descaling mill.
Background technology
Be applied in the steel pipe descaling mill of steel pipe hot rolling line; Be to adopt water under high pressure to be directly injected to steel tube surface; Lean on the impulsive force of water under high pressure to destroy the iron scale of steel tube surface; Therefore, iron scale, water under high pressure will splash out from the import and export of descaling mill, and some water flows out along steel pipe.
Existing steel pipe descaling mill generally adopts iron chains and water under high pressure to regurgitate dash, and iron chains blocks thick iron scale, and high pressure is regurgitated water and cut off the water under high pressure outwards splash and to flow out along steel pipe, and dash is respond well.But the steel pipe tube wall before sizing mill is thinner, and the water yield is excessive will to cause quenching, has a strong impact on the rolling of steel pipe, and is even more serious during particularly rolling oil conduit.Many scenes are not too large in order to guarantee the de-scaling temperature drop, reduce the de-scaling water yield, and this can have a strong impact on scale removal effect, and adopt water under high pressure to come dash, and the big energy consumption of power is high, waste water resource.
The utility model content
To above-mentioned technical problem, the utility model provides a kind of dash effect fine, the steel pipe descaling mill of the little and energy-saving and water-saving of steel pipe temperature drop.
In order to solve the problems of the technologies described above; The utility model provides a kind of steel pipe descaling mill; Comprise the de-scaling casing, this de-scaling casing is provided with import and the outlet that steel pipe passes and is installed in the high-pressure water descaling ring in the de-scaling casing, it is characterized in that; Said De-scaling box body cavity body inside is equipped with the gas blowout drip ring; This gas blowout drip ring is near import, and the axis of said gas blowout drip ring overlaps with the axis of the import of said de-scaling casing, on said gas blowout drip ring, evenly is furnished with the air nozzle that stops water under high pressure and iron scale to splash out.
Said air nozzle is towards the steel pipe orbit and towards 15 ° of angles of said Way out skew.
The good effect of the utility model is: this baffle device for water is to adopt compressed air, regurgitates to purge to replace water under high pressure to regurgitate.Iron chains blocks thick iron scale, and it is consistent that the air of the ejection water under high pressure regurgitating that cut-out is outwards splashed and flow out along steel pipe at a high speed, dash effect and water under high pressure are regurgitated effect, reduced water consumption, and using water wisely and jet energy consumption are low; Make that simultaneously the temperature drop of steel pipe de-scaling is less, reduce influence steel pipe rolling.

Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done further explain.
As depicted in figs. 1 and 2; A kind of steel pipe descaling mill; Comprise de-scaling casing 1, this de-scaling casing 1 is provided with import and the outlet that steel pipe passes, and high-pressure water descaling ring 4 and gas blowout drip ring 2 are installed in de-scaling casing 1 inside; Wherein the axis of high-pressure water descaling ring 4 overlaps with the axis of said outlet, on high-pressure water descaling ring 4, evenly is furnished with the head that sprays water with high pressure that is used for the steel pipe de-scaling; Said gas blowout drip ring 2 is near import; The axis of this gas blowout drip ring 2 overlaps with the axis of the import of said de-scaling casing 1; The top of gas blowout drip ring 2 is connected with ring flange 5 through pipeline; This ring flange 5 is used for being connected with the gas outlet of High-Pressure Compressor, on gas blowout drip ring 2, evenly is furnished with the air nozzle 3 that stops water under high pressure and iron scale to splash out, and this air nozzle 3 is towards the steel pipe orbit and towards 15 ° of angles of Way out skew.
When using this device; Through ring flange 5 this device is connected with the gas outlet of High-Pressure Compressor; The air nozzle 3 ejection gases at high pressure of installing on the gas blowout drip ring 2; Stop water under high pressure and the water under high pressure that iron scale flies and flow out along steel pipe to sputter de-scaling casing 1, this baffle device for water is to adopt compressed air, regurgitates to purge the replacement water under high pressure and regurgitate.Iron chains blocks thick iron scale, and it is consistent that the air of the ejection water under high pressure regurgitating that cut-out is outwards splashed and flow out along steel pipe at a high speed, dash effect and water under high pressure are regurgitated effect, reduced water consumption, and using water wisely and energy consumption are low; Make that simultaneously the temperature drop of steel pipe de-scaling is less, reduce influence steel pipe rolling.
The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
