Barrel tank circulation cleaning system

Abstract

A tank circulation cleaning system includes a tank equipped with a nozzle and a drain hole. The nozzle and the drain hole are connected to a storage tank via a manifold network. The tank is monitored by a control center, which generates corresponding execution commands based on the monitoring data. These execution commands include a degreasing command, a passivation command, and a hot water cleaning command, causing a liquid to circulate and clean the tank through the nozzle and the drain hole. This system solves the problems of traditional industrial tank cleaning methods that require non-heated immersion, resulting in low cleaning efficiency, long cleaning time, high consumption of chemical cleaning agents, difficulty in recycling, and difficulty in control due to inertia during rotation.

2. As described in claim 1, in the tub-sink circulation cleaning system, upon receiving the re-inspection command, the control center performs quality control testing on the tub and generates quality control test data. Based on the quality control test data, the control center generates a passivation command and executes the passivation command on the tub. After completing the passivation command execution, the control center generates a corresponding re-inspection command. Upon receiving the re-inspection command, the control center performs electrolytic polishing testing on the tub and generates electrolytic polishing test data. Based on the electrolytic polishing test data, the control center generates a hot water cleaning command and executes the hot water cleaning command on the tub. After completing the hot water cleaning command execution, the control center generates a corresponding re-inspection command. Upon receiving the re-inspection command, the tub's cleaning process is complete.

3. In the tank circulation cleaning system as described in claim 2, if the liquid meets the conductivity stability state in the re-instruction generated after the control center completes the execution of the degreasing command, then the re-instruction causes the control center to perform the mechanical polishing test on the tank. The tank passes the mechanical polishing test. The control center then performs a quality control test on the tank. If the tank fails the mechanical polishing test, the control center generates a degreasing command. After the control center completes the passivation command, a re-inspection command is generated. If the liquid meets the conductivity stability requirement, the re-inspection command causes the control center to perform a quality control test on the tank. If the tank passes the quality control test, the control center performs an electrolytic polishing test on the tank. If the tank fails the electrolytic polishing test, the control center generates a hot water cleaning command. After the control center completes the hot water cleaning command, a re-inspection command is generated. If the liquid meets the conductivity stability requirement, the re-inspection command causes the control center to perform an electrolytic polishing test on the tank. If the tank passes the electrolytic polishing test, the tank completes the cleaning procedure. If the tank fails the mechanical polishing test, the control center generates a hot water cleaning command.
