Special gas pipeline assembly and powder coating equipment

Abstract

The invention discloses a special gas pipeline assembly. The special gas pipeline assembly comprises a metal pipeline, a power source and multiple conductive fixing parts, wherein the multiple conductive fixing parts are sequentially fixed to the metal pipeline in the extending direction of the metal pipeline, the power source is connected with the conductive fixing parts through wires, the conductive fixing parts are arranged at intervals, and the portions, between the adjacent conductive fixing parts, of the metal pipeline and the power supply form loops, so that current is loaded on the metal pipeline. The current is directly loaded on the metal pipeline, the metal pipeline serves as a heating element for spontaneous heating, a traditional mode that a pipeline Is sleeved with a heating sleeve is replaced, the highest temperature resistance is the temperature resistance of the metal pipeline, thus the temperature upper limit is improved, the structure is simpler, the pipeline temperature can be directly measured, thus the temperature control precision is improved, the whole pipeline serves as a heating unit, and effects of elbows do not need to be considered, so that the cost is effectively reduced. The invention further discloses powder coating equipment comprising the assembly.

Description

Technical field [0001] FIELD The present invention relates to coating, particularly to a gas line Laid assembly. The present invention further relates to a powder coating apparatus comprising the above-described assembly. Background technique [0002] Variety of devices require specialty gases involved in the process, such as a powder coating equipment needs nitrogen delivery pipe, and heating is required during transport line. [0003] Conventional heating method is put in a heating mantle outside the conduit, a conduit heated by the heating jacket. But there is a heating mantle material temperature limit, can not exceed this temperature, as this may cause damage, resulting in maximum allowable temperature is relatively low. Complex structure while heating mantle, a heating mantle liner, the heating layer, insulation layer, crust. And the temperature sensor measures the temperature of the heating jacket, rather than piping temperature, the actual temperature of the line set valu...

AI Technical Summary

Problems solved by technology

However, the heating jacket has a material temperature resistance limit, and it cannot exceed this temperature, otherwise it may cause damage, resulting in a lower allowable maximum temperature

At the same time, the structure of the heating jacket is complex, and the heating jacket is composed of an inner lining, a heating layer, an insulation layer, and an outer skin.

And the temperature sensor measures the temperature of the heating jacket, not the temperature of the pipeline, so there is a large error between the actual temperature of the pipeline and the set value, and the temperature control error is large

Due to the complex shape of the pipeline, it needs to be divided into many segments, too many segmented units, and the cost is too high
