Abstract
Description
Technical Field
[0001] The utility model relates to the field of pickling liquid containing barrels, in particular to a semiconductor pickling liquid containing barrel. Background Art
[0002] Semiconductor pickling liquid storage barrel is one of the important equipment in the semiconductor production process. It is mainly used to store and treat pickling waste liquid. In the semiconductor manufacturing process, many steps require the use of pickling liquid to clean and remove surface impurities such as metals, oxides and other contaminants. These pickling liquids become waste liquids after use and need to be properly handled and stored to avoid pollution to the environment and harm to personnel health.
[0003] The existing semiconductor pickling liquid storage barrels are still stored in ordinary plastic barrels. The plastic barrels have a weak carrying capacity and are not easy to stack. The storage space required is large. During vehicle transportation, they still need to be stacked to save space. Since the barrels themselves cannot be effectively fixed, the bumps and ups and downs during transportation will still cause the barrels to collapse, causing the barrels to break, and the waste liquid to flow to the ground, causing corresponding impacts on the environment and passing vehicles. On the other hand, the pickling liquid stored for a long time or in hot weather will cause the gas in the barrel to expand. The existing barrels are designed with manually opened exhaust ports. When the number is large, manual repeated observation of the opening and closing is required. The stacked barrels must be transported and separated before exhausting, which is time-consuming and laborious. In addition, if the manual exhaust time is not properly controlled, the odor of the pickling liquid will spread, affecting the physical and mental health of the staff.
[0004] Therefore, a semiconductor pickling liquid containing bucket is proposed to solve the above problems. Utility Model Content

[0033] Reference Figure 4-Figure 6 , a valve frame 13 is fixedly connected to the top of the inner wall of the barrel body 7, and a fixed upper and lower gap is set on the inner wall of the valve frame 13 for gas circulation to prevent the exhaust rod 11 from getting stuck in the valve port due to excessive gas pressure.

Arc grooves are set on both sides of the outer wall of the exhaust rod 11 for gas discharge, and a valve switch 9 is fixedly connected to the top of the exhaust rod 11.
