Description

Technical Field

[0001] The invention relates to the technical field of pipeline descaling, and in particular to a device for quickly changing a descaling header. Background Art

[0002] The purpose of descaling is to remove the iron oxide scale to prevent it from being pressed into the surface and causing defects, thereby improving the surface quality of the product; methods: bamboo branches, apricot strips, salt or roller presses, wire brushes, compressed air, steam blowing, descaling machines and high-pressure water, etc. High-pressure water descaling boxes and high-pressure water nozzles before and after the rolling mill are most suitable. The water pressure is increased from 12MPa to more than 15-25MPa, and the water pressure for alloy steel is even higher. In the production process of steel plant pipelines, the iron oxide scale generated after the pipeline is heated needs to be removed by high-pressure water jetting. There are strict requirements on the spraying distance. In the actual production line, there are various specifications of steel pipes involved, corresponding to several descaling headers. When changing to other specifications of steel pipes, the descaling header needs to be replaced at the same time.

At the same time, since a through hole is provided on the rotating sealing ring 11, when the motor 7 drives the central tube I 3 and the central tube II 4 to rotate, the connection shell 1 is in a fixed state. At this time, the central tube I 3 will rotate in the connection shell 1; one of the inlets provided on the connection shell 1 (one of the inlets A201, B, C and D) will be connected to the communicating hole (the communicating port is The connecting hole corresponding to the inlet is connected, and the remaining inlets will be blocked by the rotating sealing ring 11; the water in the connecting hole enters the water inlet hole, and then enters the corresponding connecting hole and is discharged from the water outlet to enter the dephosphorization equipment; like this, in actual use, by fixing the descaling component on the central tube I3, the central tube 2 is driven to rotate by the motor 7 to realize the automatic switching of the high-pressure waterway, which has the advantages of simple structure and easy use; at the same time, the connecting pipe of the dephosphorization component is installed on the central tube I3, and the switching of descaling components 19 of different specifications can also be realized.
