Description

TECHNICAL FIELD

[0001] The utility model relates to electrolytic workshop cooling technical field, concretely relates to a kind of electrolytic workshop closed cooling tower water inlet system. BACKGROUND

[0002] In electrolytic workshop, water cooling is needed, and low-temperature water enters the water supply system after being cooled by the cooling tower. After the low-temperature water cools the target medium, it is circulated back to the cooling tower for the next cooling. This circulation process is a common water cooling circulation system. However, if the cooling water pipe is blocked or other faults occur during use, the cooling water cannot reach the cooling medium, which will seriously affect the normal electrolysis process. Therefore, a water storage tank or a separate water control system is usually set between the cooling tower and the equipment that needs to be cooled to ensure the supply of cooling water.

[0003] A blast furnace circulating cooling water flow control system is disclosed in Chinese patent CN215983998U. The patent discloses that by setting the filter pipe and the shunt pipe, multiple independent cooling water flow channels can be formed between the water storage tank and the cooling pipe, ensuring that cooling water can still flow into the cooling pipe when one of the cooling water flow channels cannot normally flow. The control system is divided into two independent cooling water inlet pipes, and a filter bin is set in each pipe to remove impurities and prevent impurities from directly entering the cooling pipe, causing the cooling pipe to be blocked and burst. However, this filter bin needs to be cleaned regularly, and the long-term accumulation of impurities on the large surface area of the bin makes cleaning difficult and inconvenient to maintain.

[0004] Therefore, the present embodiment provides an electrolytic workshop closed cooling tower water inlet system to optimize the water inlet system. UTILITY MODEL CONTENTS

[0020] In the electrolytic workshop, water cooling is needed, and low-temperature water from the cooling tower enters the water supply system after cooling. After the low-temperature water cools the target medium, it is circulated back to the cooling tower for the next cooling. This cycle is a common water cooling cycle system. However, if the cooling water pipe is blocked or other faults occur, the cooling water cannot reach the cooling medium, which will seriously affect the normal electrolysis process. Therefore, a water storage tank or a separate water control system is usually set between the cooling tower and the equipment that needs to be cooled to ensure the supply of cooling water.
