Boiler-free and steam-free fire hose vulcanization process

Abstract

The invention discloses a boiler-free and steam-free vulcanization process for a fire hose. The boiler-free and steam-free vulcanization process comprises the following steps: a cylindrical lining adhesive layer coated with a binder sleeves a cylindrical braid layer; a long rope penetrates the inner hole of a well sleeved double-layered water hose; a draw hook at the front end of an electric heating rod and a running gear are connected through the long rope; the rear end of the electric heating rod is connected with an electric control device through a spiral cable; the front end of the electric heating rod sleeves the head part of the double-layered water hose; the head part of the double-layered water hose is fixed; the electric heating rod is started while the heating temperature of the electric heating rod is automatically adjusted; the running gear is started up to control the running speed of the electric heating rod in the double-layered water hose; while running, the electric heating rod softens the lining adhesive layer and expands the diameter; meanwhile, the cohesiveness of the binder is enhanced to enable the lining adhesive layer and the braid layer to be bonded together. The boiler-free and steam-free vulcanization process has the advantages that the fire hose can be vulcanized without steam and matched boilers, so that sewage discharge is avoided; the factory area and the investment are reduced, and the manufacturing cost is low; the technological process is safe and environment-friendly.

Description

technical field [0001] The invention relates to a production process of a fire-fighting hose, in particular to a vulcanization process of a boiler-free and steam-free fire-fighting hose. Background technique [0002] In the manufacturing process of the fire hose, the last process is to place the semi-finished product on the steam vulcanization table, fix and clamp the two ends, and then pass high-pressure steam into the inner lining for vulcanization. This process must use steam, and it must be equipped with a boiler. The disadvantages brought about by this are: [0003] 1. The use of steam and boilers is a high-risk industry, prone to accidents, requiring regular safety inspections; [0004] 2. The use of steam vulcanization process will produce sewage discharge, and the use of boilers to produce steam will pollute the environment. Boilers are still equipment that the country advocates to eliminate; [0005] 3. The steam vulcanization workshop has a large investment, and ...

AI Technical Summary

Problems solved by technology

This process must use steam, and it must be equipped with a boiler. The disadvantages brought about by this are:

[0003] 1. The use of steam and boilers is a high-risk industry, prone to accidents, requiring regular safety inspections;

[0004] 2. The use of steam vulcanization process will produce sewage discharge, and the use of boilers to produce steam will pollute the environment. Boilers are still equipment that the country advocates to eliminate;

[0005] 3. The steam vulcanization workshop has a large investment, and the workshop covers a large area, requiring 500-1000 square meters;

[0006] 4. Using the steam vulcanization process, the length of the fire hose is limited by the length of the vulcanization workshop
