Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide loading and unloading, in particular to an automatic hydrogen peroxide unloading device. Background Art

[0002] Hydrogen peroxide is a common oxidant and bleaching agent used extensively in various industrial fields. However, hydrogen peroxide poses certain risks during transportation and unloading, including spillage, corrosion, and volatilization. Traditional unloading methods often rely on manual operation. The unloading valve is manually connected to the pipe, and the hydrogen peroxide is pumped into the storage tank via a discharge pump. The connection between the unloading valve and the pipe poses a risk of leakage. Furthermore, the liquid level in the tank must be manually monitored to control the amount of hydrogen peroxide entering the tank and prevent overflow. After discharge, the hydrogen peroxide in the pipe must be poured out to prevent accumulation of hydrogen peroxide in the pipe and unloading valve.

[0003] The utility model patent with authorization announcement number CN206708733U discloses a hydrogen peroxide unloading device, including an unloading pump 1, a buffer tank 2 and a hydrogen peroxide storage tank 3, characterized in that: the unloading pump 1 is connected to the buffer tank 2 through a feed pipeline 4, the buffer tank 2 is connected to the hydrogen peroxide storage tank 3 through a discharge pipeline 5, a first check valve 6 is provided at the outlet of the unloading pump 1, a liquid level gauge 7 is provided in the buffer tank 2, a first thermal insulation layer 8 is provided on the inner tank wall of the buffer tank 2, a second thermal insulation layer 9 is provided on the inner tank wall of the hydrogen peroxide storage tank 3, a liquid level sensor 10 and an alarm device 11 are provided on the hydrogen peroxide storage tank 3 to cooperate with each other to control the liquid level of the hydrogen peroxide storage tank 3, and a second check valve 12 is provided on the discharge pipeline 5. The hydrogen peroxide tank truck 14, the unloading pump 1, the feed pipeline 4, the buffer tank 2, the discharge pipeline 5 and the hydrogen peroxide storage tank 3 are connected in sequence. In this patent, after the hydrogen peroxide is transferred to the storage tank, it will remain in the buffer tank, the feed pipeline and the discharge pipeline. When the unloading pump is separated from the hydrogen peroxide transport truck, it is easy to cause hydrogen peroxide leakage and contamination. Utility Model Content
