[0030] The use process of the energy-saving and reliable cooling water circulating device is as follows:

[0031] I. Preparation before starting

[0032] Before starting the cooling water circulating device, it is necessary to check whether the water storage tank 1, water pipe 2, water filtering cylinder 3, power equipment 4 (reduction motor), acid-base solution box 10, pH meter 14, temperature instrument 13 and various pipes and valves are intact and have no leakage or damage;

[0033] An appropriate amount of cooling water is added to the water storage tank 1 through the cooling water adding pipe 8 until the predetermined water level is reached. During the addition process, the change in water level can be observed through the transparent window 11 to ensure the accuracy of the amount added;

[0034] According to actual needs, an appropriate amount of acid or alkali solution is added to the water storage tank 1 through the acid solution chamber or alkali solution chamber in the acid-base solution box 10 to adjust the pH value of the cooling water to an appropriate range.

[0035] Turn on the power switch of the cooling water circulating device to ensure that the power equipment 4 (reduction motor) and other electronic equipment (such as the pH meter 14 and temperature instrument 13) can work normally.

[0036] II. Starting and running

[0037] Start the reduction motor to drive the water pipe 2 and the water filtering cylinder 3 to start rotating, and at the same time, the stirring rod 12 will also rotate to help mix and uniform the cooling water;

[0038] After confirming the normal operation of the power device 4, the cooling water output valve is opened to enable the cooling water to be delivered to the fermentation equipment in need of cooling through the variable frequency water pump 7 and the flow meter, while the cooling water is returned through the cooling water return pipeline 5, and the returned cooling water is filtered by the water filter cylinder 3 to ensure the water quality;

[0041] III. Shutdown and maintenance

[0042] When the fermentation equipment no longer needs cooling, the cooling water output valve should be closed to cut off the supply of cooling water;

[0043] The operation of the speed reduction motor is stopped through the control panel or remote controller to stop the rotation of the water pipe 2 and the water filter cylinder 3, and the power switch is turned off to ensure that the entire device is in a safe state;
