Improved process of steam generator for malacia protection of enamelling bare wire as well as apparatus

Abstract

Provided is an improved method of the enamelling bare wire softening protection steam generator and a device, wherein a cooling water inlet communicates with a T-shaped intake pipe from the bottom of the outer liner, the wrapped heat collection sheet causes the cooling water fully heated before entering the inner water tank, which increases the endotherm area and reduces the flow velocity of the cooling water. Two staggered insulation boards are arranged at the bottom and the middle of the water tank between the outer liner and the inner water tank to form a sealing channel with reverse direction, to lead the exhaust gas to revolve for two 180-degree greater curvature in the outer liner sealed channel and then to be discharged. The upper of the T-shaped intake pipe penetrates into the intake pipe laid at the lower part of the inner water tank with the two ends closed and a row of eyelets is arranged at the lower part as the outlets, further reducing the effect on the temperature of the evaporating surface. Two staggered baffle plates are provided, which makes the residence time of the air in the outer liner appropriate, completely exchanges the remaining heat carried by the waste gas with the inner water tank, ensures enough steam continuously to output from the outlet of the steam.

Description

technical field [0001] The invention belongs to the technical field of enameled wire production, and is particularly suitable for an improved method and device for a steam generator for softening and protecting enameled bare wires. Background technique [0002] In the production of enameled wire, the softening of the bare wire is a very important process. It can eliminate the drawing stress of the bare wire and improve the softness of the bare wire, but it cannot be oxidized during the softening process. Usually, the bare wire is treated with steam. Protect. [0003] The steam generators equipped by existing equipment manufacturers are generally dual energy sources, using both waste gas heating and electric heating. The waste gas enters the generator from the bottom, the water enters the inner water tank from the middle, and the upper part outputs steam. See the structure. figure 1 , its shortcomings are: [0004] 1. The power consumption is large. Each generator should be...

AI Technical Summary

Problems solved by technology

[0006] 3. The production of enameled wire is carried out continuously. Any short-term interruption of steam will cause oxidation of the bare wire, which is extremely unfavorable to the production of enameled wire, especially for large-capacity winding. It can be said to be fatal. The qualified products that have been produced The enameled wire can only be scrapped due to insufficient delivery weight, which makes the production unable to proceed normally
