Description

Technical Field

[0001] This utility model relates to the technical field of low-pressure storage tank accessories, specifically a low-pressure storage tank external cooling circulation device. Background Technology

[0002] Low-pressure storage tanks are widely used in the chemical, energy, food processing, water treatment, and pharmaceutical industries for the storage and handling of various liquid or gaseous media. Their main characteristics are low operating pressure and large volume, making them suitable for applications where the pressure requirements of the stored medium are not high, but temperature stability and sealing must be ensured.

[0003] During storage, the tank is prone to temperature rise due to changes in ambient temperature, solar radiation, or internal media reactions, leading to problems such as increased internal pressure, accelerated media evaporation, or system instability. Traditional tank cooling methods mostly involve internal cooling coils or external spray cooling. These methods have disadvantages such as complex structure, inconvenient maintenance, low cooling efficiency, and high water consumption. Especially in situations with high external ambient temperatures or high requirements for cooling speed, they cannot meet the requirements for process stability.

[0004] Therefore, it is necessary to design a low-pressure storage tank external cooling circulation device to solve the above problems. Utility Model Content

Second U-shaped blocks are rotatably connected to both ends of the two insert shafts, and T-shaped blocks are fixedly sleeved on the tops of both second U-shaped blocks. Two symmetrical T-shaped grooves are opened at the bottom of the lifting plate, and the two T-shaped blocks are slidably engaged inside the two T-shaped grooves.
