Device capable of cleaning outer wall of nodular cast iron pipe or pipe mold

Abstract

Disclosed is a device capable of cleaning the outer wall of a nodular cast iron pipe or pipe mold. The device comprises at least two supporting wheels, a support, a rail, a trolley and a laser cleaning machine; the rail is arranged above the support, the at least two supporting wheels are mounted under the rail, the nodular cast iron pipe or pipe mold is placed on at least two supporting wheels, the trolley is arranged on the rail, and can walk on the rail, the laser cleaning machine is arranged on the trolley, and the laser cleaning machine is aligned at the outer wall of the nodular cast iron pipe or pipe mold to emit lasers. According to the device, in the production process of the nodular cast iron pipe, due to rust removal of the outer wall of the nodular cast iron pipe or descaling of the outer wall of the pipe mold, quick-wear part consumption is reduced, the wear of other descaling and rust removal manners to the outer wall of the nodular cast iron pipe or pipe mold is completely eradicated, the quality of nodular cast iron pip finished products can be improved, and the cleaning device can be used for carrying out rust removal treatment on the nodular cast iron pipe, and also can be used for descaling treatment of the pipe mold.

Description

technical field [0001] The invention relates to a device for cleaning the outer wall of ductile iron pipes or pipe molds in the production of ductile iron pipes. It is used to remove rust on the outer walls of ductile iron pipes or scales on the outer walls of pipe molds. Sand blasting device and external wall grinding device for cleaning the outer wall of cast iron pipe or pipe mold. Background technique [0002] In the production of ductile graphite pipes, the production process requires spraying zinc on the outer wall of the pipe to improve the anti-corrosion ability of the pipe. In order to prevent the corrosion of the pipe and improve the adhesion of the zinc layer, the outer wall of the pipe needs to be cleaned before spraying zinc. Attached debris and rust. At present, there are two main processes for cleaning the outer wall, one is external shot blasting, and the other is grinding the outer wall with a wire wheel brush. Among these two technologies, the rust remova...

AI Technical Summary

Problems solved by technology

Among the two technologies, the descaling effect of external sandblasting is good, but the consumption of steel grit and the wearing parts of the sandblasting machine is large, which increases the manufacturing cost of the pipe, and the outer wall of the pipe mold after sandblasting is rough, which makes the next time The scale generated during use has stronger adhesion and is more difficult to clean

Sand blasting will cause certain wear on the metal surface of the outer wall of the pipe mold, which will have a certain impact on the life of the pipe mold, so it is rarely used

[0005] Now, whether it is derusting of ductile iron pipes or descaling of pipe molds, it is generally manually polished with a hand-held angle grinder. Some wear on the outer surface of the ductile iron pipe or pipe mold

In addition, the consumption of the grinding wheel is large, and the dust is large during grinding, causing environmental pollution
