Rotary turbulent tube energy-saving water cooling device

Abstract

The invention discloses an energy-saving rotary turbulent tube through-water cooling device which is characterized in that a driving liner tube and more than one driven liner tube are sequentially mounted in an inner cavity of a liner bracket tube; a transmission gear is processed at the outer wall of the driving liner tube; a driven gear box is mounted at the outer wall of the front end of the liner bracket tube; a driven gear is arranged on a driven gear box rotating shaft mounted in the driven gear box, and is engaged to the transmission gear; a driving gear box and a driving gear box front cover that are connected with each other are arranged at the top end of the driven gear box; the two ends of a driving gear rotating shaft provided with a driving gear engaged to the driven gear are positioned in or penetrate through bearings of the driving gear box and the driving gear box front cover; a rotating shaft Y-shaped sealing ring on the driving gear rotating shaft is inserted into the driving gear box front cover; and a shaft end cover is connected with the driving gear front cover. With the adoption of the device, synchronous rotation of the driving liner tube and the driven liner tubes and rotation of rolled metal can be realized. The service life of the whole device, a heat-exchange rate and a finished product rate of the rolled metal can be increased, and the device has practical values and popularization values.

Description

technical field [0001] The invention relates to a cooling device, in particular to a rotary turbulent tube energy-saving water-through cooling device used in the controlled rolling process of threaded steel bars in industrial and civil buildings to make the threaded steel bars cool evenly and minimize / reduce surface wear. Background technique [0002] At present, after passing through the last pass (K1 pass) in the threaded steel rolling process, the controlled cooling technology is also used to cool the threaded steel bar through water to improve the strength (but increase the brittleness). The process / apparatus used is to pass it through a roll tunnel or liner and allow it to cool. Before the present invention, there was CN203678885U "combined non-steam water-piercing cooling device" and application number 201510196208.X "water-piercing mechanism". The general-purpose structure is that the positions of the multiple turbulent tubes installed in the liner are fixed during t...

AI Technical Summary

Problems solved by technology

The general-purpose structure is that the positions of the multiple turbulent tubes installed in the liner are fixed during the cooling process of the rolled material, and cannot be rotated or rotated as required, so that one side (that is, close to the turbulent flow) One side of the turbulence tube) always has contact or friction with the bottom surface of the turbulence tube. After a period of use, the bottom surface of the turbulence tube is worn and needs to be stopped for maintenance and replacement; at the same time, the contact surface of the threaded steel bar cooled by water is also worn in different procedures, reducing quality

Water piercing equipment needs to be improved due to shortened service life, increased maintenance and production costs
