Description

Rotary Steel Pipe Ash Blowing and Suction Device

technical field

The utility model relates to a steel pipe heat treatment production line, in particular to a rotary steel pipe ash blowing and suction device.

Background technique

After the heat treatment of the steel pipe, in order to ensure the quality of the steel pipe, it is usually necessary to conduct a flaw detection inspection on the steel pipe. In order to ensure the reliability of the flaw detection inspection, it is necessary to remove the scale and debris remaining on the inner wall of the steel pipe. In this regard, steel pipe manufacturers need to use soot blowing and suction equipment to clean the inner wall of the steel pipe. At present, most of the soot blowing and suction devices used by enterprises are open structures. The soot blowing and suction processes are: feeding, aligning the blowing ends, sealing the blocking plates at both ends, blowing and suctioning soot, removing the plates at both ends, and unloading. This soot blowing and suction process has the disadvantage of poor sealing at both ends of the steel pipe, which easily causes air pollution, affects normal production, and has low production efficiency.

The existing soot blowing and suction equipment uses a hydraulic cylinder to lift the gland to achieve airtightness. During the rotation process, no righting measures are adopted, and no braking device is equipped. After the equipment has been in operation for a long time, the airtightness is often not tight, and work site pollution occurs. Larger, equipment bearing damage occurs from time to time, affecting the efficiency of normal processing of steel pipes.

In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows: a rotary steel pipe ash blowing and suction device, which includes a main machine, a turntable, an adjustable air blowing head, and an ash suction head. Cover, the bottom of the beam is hinged with a gland, the bottom of the gland is provided with a turntable, and there are 6 V-shaped chambers evenly distributed around the circumference of the turntable, and diameters are arranged between adjacent V-shaped chambers. To the roller device, the V-shaped chamber is provided with a U-shaped steel pipe bracket, the inner wall of the U-shaped steel pipe bracket is provided with a U-shaped polyurethane bracket, the side wall of the gland is provided with rubber skins, and the gland , V-shaped chamber and rubber skin form a closed space.

The beneficial effects of the utility model are as follows: the steel pipe to be treated is placed in a closed space composed of the gland, the V-shaped chamber and the rubber skin, and a combination of blowing and suction is adopted. Gravity dust collector, cyclone dust collector, bag filter and three-stage dust collector collect dust, which solves the problem of incomplete removal of impurities such as scale on the inner wall of steel pipes and pollutes the working environment in the prior art, and achieves real energy saving and emission reduction. Through the use of the utility model, when the steel pipe to be processed enters the turret from the feeding frame, the previous steel pipe that has been processed is discharged from the discharge frame, and the cycle operation greatly improves the working efficiency of the steel pipe ash blowing operation. .
