Nodular cast iron pipe ceramic lining layer coating equipment and forming process

Abstract

The invention relates to the technical field of nodular cast iron pipe ceramic lining forming, and provides nodular cast iron pipe ceramic lining layer coating equipment and a forming process. The nodular cast iron pipe ceramic lining layer coating equipment comprises a pipe manufacturing centrifugal machine and a pipe drawing bench, the pipe drawing bench is located at one side of the pipe manufacturing centrifugal machine and is used for drawing out a formed nodular cast iron pipe from a pipe die of the pipe manufacturing centrifugal machine, and the equipment further comprises a lifting device, a coating mechanism, a conveying mechanism and an annealing furnace. The lifting device is located at one side of the pipe drawing bench, a tug set is rotationally arranged on the lifting device and used for bearing the nodular cast iron pipe, the coating mechanism is arranged at one side of the lifting device and used for coating the inner wall of the nodular cast iron pipe on the tug set with a ceramic coating, the conveying mechanism is arranged below the tug set, and the input end of the annealing furnace is connected with the output end of the conveying mechanism. By means of the technical scheme, the problems that in the prior art, the forming quality of a nodular cast iron pipe ceramic lining layer is poor, and energy is wasted are solved.

Description

technical field [0001] The invention relates to the technical field of forming the inner lining layer of ductile iron pipes, and in particular relates to lining equipment and a forming process for the ceramic inner lining layer of ductile iron pipes. Background technique [0002] The processing of the ceramic coating is usually achieved by high-temperature calcination. In the prior art, the ceramic coating on the inner wall of the steel pipe has been realized in the industry, but it is still a technical problem to apply the ceramic coating on the inner wall of the ductile iron pipe. [0003] The smoothness of the inner wall of the steel pipe is much more uniform, the wall thickness is very uniform, and the temperature control can be realized very simply. However, the ductile iron pipe does not have these characteristics of the steel pipe, and it is difficult to achieve a stable and uniform temperature of the overall ductile iron pipe, which leads to It is very difficult to f...
