Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an electrochemical descaling device that can be maintained in sections. Background Technology

[0002] Electrochemical descaling is a technology that uses electrochemical reactions to remove calcium and magnesium ions from water, thereby preventing scale formation. During the electrochemical descaling process, some dirt will accumulate on the electrode plates, and this dirt needs to be treated; otherwise, it will affect the treatment effect.

[0003] Some wastewater treatment equipment on the market uses scrapers to remove dirt from electrode plates. However, after prolonged use, these electrode plates still need to be removed for replacement or maintenance. Furthermore, some equipment assembles the electrode plates into a single module. Replacing or maintaining the electrode plates in such equipment requires shutdown, impacting the wastewater treatment process.

[0004] For example, Chinese patent application number CN202210783259.2 discloses an electrocoagulation wastewater treatment device, specifically disclosing that "a descaling cylinder is fixedly installed at the top of the support leg, an arc-shaped cylinder is welded and fixedly installed on the bottom surface of the descaling cylinder, and an aluminum arc-shaped plate is fixedly installed inside the descaling cylinder near the top; a flange plate is welded and fixedly installed on one short side surface of the support leg at the top, a support frame is welded and fixedly installed on one short side surface of the support leg near the top, a drive motor is fixedly installed at the top of the support frame, a connecting shaft is fixedly installed at the output end of the drive motor, and circular scrapers are fixedly installed at equal intervals on the surface of the connecting shaft." In this type of device, the electrode plates are assembled together to form an electrode module. When replacing or maintaining the electrode plates, the device needs to be shut down for maintenance, affecting the wastewater treatment progress.

[0005] For example, Chinese patent application CN202021121918.9 discloses an electrochemical water treatment device, specifically stating that "the electrochemical reaction device includes a tank, electrode plates, a descaling mechanism, and an inlet pipe connected to the tank; the electrode plates include cathode plates and anode plates staggered inside the tank." In this type of device, the electrode plates are assembled together to form an electrode module. Replacing or maintaining the electrode plates requires stopping the machine for maintenance, affecting the wastewater treatment progress. Utility Model Content
