As the most important link in the process flow, the low-temperature cooling circulation system plays a vital role in the efficient and reliable operation of the system. However, the current circulation tanks and pipelines that transport low-temperature cooling circulation media are prone to residual impurities in the pipeline walls due to long-term use. It is not convenient to change the problem of residual impurities in the pipeline by filtering the medium alone. Utility Model Content

[0012] Preferably, a handle is installed on the cover plate.

[0013] Compared with the prior art, the beneficial effects of this patent are: the low-temperature cooling circulation tank has the following advantages compared with the traditional technology:

[0014] 1. The first pump body draws the medium in the water tank through the vertical pipe and enters the horizontal pipe, while the cooling pipe can cool the medium passing through the horizontal pipe at low temperature. At the same time, the second pump body discharges the medium in the horizontal pipe into the water tank through the inclined pipe, forming a low-temperature cooling cycle; when it is necessary to clean the residual impurities in the horizontal pipe, the cycle stops working.
