Description

Technical Field

[0001] This utility model relates to the field of pretreatment technology for circulating water, and in particular to a pretreatment structure for industrial circulating water. Background Technology

[0002] The pretreatment structure for industrial circulating water is a modular treatment device installed between the water inlet at the front end of the industrial circulating water system and the circulating water pump or heat exchanger. Its core function is to perform targeted purification treatment on the raw water entering the circulating system, such as tap water, groundwater, and surface water, to remove or control harmful impurities that may affect the stable operation of the system, and to provide a pretreatment unit with qualified water quality for the circulating water system.

[0003] In industrial production, the quality of circulating water has a significant impact on the normal operation of production equipment and product quality. In order to accurately detect various indicators of industrial circulating water, it is necessary to collect water samples and preserve them. The existing patent (publication number: CN223303166U) includes a storage box, the inside of which is provided with an inner layer block. Multiple placement slots are arranged on the top of the inner layer block, and movable slots are symmetrically formed on the inner surface of each placement slot. In this invention, when a water sample bottle containing industrial circulating water is inserted into the placement slot, the rubber-plastic sponge sleeve inside the placement slot will press against the compression plate. At this time, the compression plate compresses the spring. When the water sample bottle is fully inserted, the compressed spring will generate a compressive force, causing the compression plate to continuously compress the rubber-plastic sponge sleeve, thereby forming a compression and reinforcement effect on the water sample bottle inside the rubber-plastic sponge sleeve. Furthermore, the rubber-plastic sponge sleeve is relatively soft and will completely adhere to the surface of the water sample bottle, resulting in high friction. Therefore, this device provides high stability when storing water sample bottles containing industrial circulating water, preventing damage or leakage caused by shaking during transportation.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, current pretreatment methods for industrial circulating water typically involve directly filtering the circulating water using a filter screen. While this method can treat the circulating water, its effectiveness and efficiency are limited, its structure is relatively simple, and it cannot achieve other auxiliary effects during the pretreatment of circulating water, thus lacking practicality.

[0005] Therefore, a pretreatment structure for industrial circulating water is proposed. Utility Model Content
