Online automatic copper pipe purging device

Abstract

The invention discloses an online automatic copper pipe purging device which comprises a copper pipe purging sealing base and an air inflating sealing ring. A cylindrical sealing cavity for a copper pipe to be inserted is formed in the copper pipe purging sealing base. A ring-shaped sealing cavity is formed in the portion, located on the middle portion of the cylindrical sealing cavity, of the copper pipe purging sealing base. A nitrogen conveying channel is formed in the copper pipe purging sealing base. The air inflating sealing ring is installed in the ring-shaped sealing cavity. An air inflating short pipe is connected to the air inflating sealing ring. One end of the air inflating short pipe extends into the air inflating sealing ring and communicates with an air inflating cavity of the air inflating sealing ring, and the other end of the air inflating short pipe extends out of the copper pipe purging sealing base and is connected with the air supply end of an air compressor through a pipeline. According to the online automatic copper pipe purging device, nitrogen is effectively prevented from being leaked from the cylindrical sealing cavity to the outside, it is ensured thatthe nitrogen can only enter the inner cavity of a copper pipe to carry out purging, the inner wall purging quality of the copper pipe is ensured, and the inner wall cleanness degree of the copper pipeis improved.

Description

technical field [0001] The invention relates to the technical field of copper pipe production equipment, in particular to an online automatic purging device for copper pipes. Background technique [0002] During the drawing process of the copper tube, lubricating drawing oil should be added, and the finished coil after annealing has strict restrictions on the amount of residual oil on the inner and outer walls of the tube, so the copper tube coil needs to be cleaned during the annealing process. Its inner wall is purged. [0003] see figure 1 , shown in the figure is the existing copper pipe online automatic purging device, including copper pipe purging sealing seat 10 and silicone tube 20, copper pipe purging sealing seat 10 constitutes a cylindrical seal for copper pipe 1 insertion Cavity 11, one end of cylindrical sealed cavity 11 is positioned on the side wall of copper pipe purging seal seat 10 and is formed as a copper tube insertion port 11a, and its other end is cl...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: aiming at the problems existing in the existing copper pipe online automatic purging device, to provide a method to ensure the cleaning quality of the inner wall of the copper pipe, improve the cleanliness of the inner wall of the copper pipe, reduce the cost of equipment debugging, and reduce the labor of workers. High-strength copper tube online automatic purging device, this device also effectively solves the problems of tube jamming when the copper tube is automatically inserted, unreliable sealing of the silicone tube, easy damage and high frequency of replacement
