Anti-corrosion microelectronic ultra-pure chemical material storage tank

Abstract

The invention discloses an anti-corrosion microelectronic ultra-pure chemical material storage tank. The tank comprises a storage tank body and a sealing cover; the sealing cover is mounted and fixedat the upper end of the storage tank body; an airtight fixing block composed of a bottom rubber ring, a sleeving rubber ring, an internal through hole, an upper side folding groove and a lower side folding groove can well seal the joint of a discharging pipeline; during closed sealing, the sleeving rubber ring of the airtight fixing block is inserted and fixed on the inner side of the dischargingpipeline, so a good sealing effect is achieved; during closed extrusion, the sleeving rubber ring passes through a fixed area of the internal through hole so as to well contact with the material; thesleeving rubber ring is deformed and folded through a folding groove in the upper side to effectively block the connecting gap, and the bottom rubber ring is deformed and folded through the folding groove in the lower side to effectively seal the closed gap, so that the inner gap and the outer gap are both sealed and changed, and the leakage of the material is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion microelectronic ultra-pure chemicals, in particular to a material storage tank for anti-corrosion micro-electronic ultra-pure chemicals. Background technique [0002] Storage tanks are therefore required when storing ultrapure chemicals for anti-corrosion microelectronics. The storage tank is a steel sealed container used to store liquid or gas, that is, a steel storage tank. The steel storage tank project is indispensable for industries such as petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, and national defense. As important infrastructure, our economic life is always inseparable from large and small steel storage tanks. The important role played by steel storage tanks in the development of the national economy is irreplaceable. With the continuous development of the storage tank industry in front of us, more and more industries and enterpr...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an anti-corrosion microelectronic ultra-pure chemical material storage tank, to solve the problem that the existing anti-corrosion microelectronic ultra-pure chemical material storage tank discharge pipeline proposed in the above-mentioned background technology is sealed and fixed. The airtightness of the sealed and fixed rubber pad is poor, which is prone to material leakage, and the cost is high and energy is wasted during work.
