Description
Technical Field
[0001] The present invention belongs to the technical field of electronic chemical storage, and in particular relates to a high-protection storage tank for storing semiconductor electronic chemicals. Background Art
[0002] In the current field of electronic chemical storage technology, semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communications systems, photovoltaic power generation, lighting, and high-power power conversion. Diodes, for example, are devices made from semiconductors. Their processing requires electronic chemicals as raw materials, also known as electronic chemical materials. This broad term refers to specialized chemicals and chemical materials used in the electronics industry, specifically the various chemicals and materials used in the production and packaging of electronic components, printed circuit boards, and industrial and consumer devices. These chemicals can be categorized by application, including substrates, photoresists, electroplating chemicals, packaging materials, high-purity reagents, specialty gases, solvents, pre-cleaning dopants, solder masks, acids and etchants, specialized electronic adhesives, and auxiliary materials. Due to the toxicity of some electronic chemicals, they must be stored in protective tanks.
[0003] The invention patent with authorization announcement number CN110294220B discloses an anti-expansion storage tank for storing semiconductor super chemicals, including a tank body, which is a hollow cylindrical body. A feed pipe is fixedly connected to the center of the top surface of the tank body, and the feed pipe is connected to the interior of the tank body. A support foot is fixedly installed on the bottom of the tank body. The anti-expansion storage tank for storing semiconductor super chemicals, through the provision of a pressure relief column, can absorb the pressure when the liquid in the tank body expands, thereby avoiding chemical gushing when the tank is opened, and the pressure relief column will protrude from the pressure relief hole as the pressure increases to help the user observe the pressure condition of the liquid in the tank body. The anti-expansion storage tank for storing semiconductor super chemicals, through the provision of a leakage box, can receive the liquid that cannot be decompressed inside the tank body and causes it to seep out of the pressure relief hole, thereby avoiding pollution problems caused by the chemical liquid seeping into the external environment. The user can observe the leakage condition through the glass plate, and can also remove the glass plate to operate the pressure relief column.
[0004] However, the above patents have the following shortcomings:
[0005] 1. The above patent can absorb the pressure through the pressure relief column to avoid the gushing of chemicals when the can is opened. However, the chemicals are prone to produce harmful gases, which are easily leaked from the pressure relief column during pressure relief, causing safety hazards.

When semiconductor chemicals are stored in the above-mentioned patents and commonly used storage tanks, some chemicals are easily affected by external temperature and easily react when heated after long-term storage.

The water pump 51 transports the cooling water to the water pipe 52, which is sprayed out by multiple nozzles 53, thereby cooling the inner tank body 3.
[0056] The inner wall of the inner tank body 3 is provided with a corrosion-resistant layer 34 , and the inner wall of the storage tank body 2 is provided with a heat-insulating layer 21 , which is filled with heat-insulating material.
