Technologic nozzle and thermal circulation heat-insulation device for same

Abstract

A thermal circulation heat-insulation device for a technologic nozzle comprises a cavity, an upper comb-shaped flow stopping plate and a lower comb-shaped flow stopping plate, wherein a heat exchanging chamber is formed in the cavity; the upper comb-shaped flow stopping plate comprises a cover plate and a plurality of upper flow stopping sheets; the lower comb-shaped flow stopping plate comprises a bottom plate and a plurality of lower flow stopping sheets; the lower flow stopping sheets and the upper flow stopping sheets are distributed in the heat exchanging chamber in a staggered manner; a circulation liquid inlet and a circulation liquid outlet are respectively formed in two ends of the cover plate; and the heat exchanging chamber, the upper comb-shaped flow stopping plate and the lower comb-shaped flow stopping plate form a snakelike heat exchanging channel. The invention also provides a technologic nozzle comprising the thermal circulation heat-insulation device. The snakelike heat exchanging pipe is used in the thermal circulation heat-insulation device, the heat exchanging area is large, the heat exchanging efficiency is high, and an external circulation liquid delivery pipeline and the inner structure of the heat-insulation device are skillful, so that the thermal circulation heat-insulation device is easy to operate. The thermal circulation heat-insulation device is arranged in the technologic nozzle, therefore, sufficient heat exchange is guaranteed, the volume of the chamber in the technologic nozzle is reduced, and the temperature of work liquid stored in the chamber is well guaranteed.

Description

technical field [0001] The invention relates to an accessory of process equipment for forming a uniform water curtain, in particular to a thermal cycle heat preservation device and a process nozzle for a process nozzle. Background technique [0002] At present, the process nozzles used in practice require the working liquid to work at a normal temperature of 25 degrees Celsius. The method to ensure a constant temperature is generally to use a constant temperature workshop to ensure that the development environment is 25 degrees Celsius. Wrap a layer of hot circulating water circulation pipes, wherein the temperature of the hot circulating water is 25 degrees Celsius. The temperature of the constant temperature work room has little effect on the heat preservation of the working liquid, and the heat transfer efficiency is low; the method of wrapping the heat circulating water pipe outside the working liquid pipe will make the diameter of the working liquid transportation pipe ...
