[0024] During implementation, by adding cooling water to be descaled into the first cavity 110, the volume of the first cavity 110 increases, thereby pushing the annular sealing plate 310 to slide, and scraping off the scale accumulated on the second cavity 120. Similarly, by adding cooling water to be descaled into the second cavity 120, the volume of the second cavity 120 increases, thereby pushing the annular sealing plate 310 to slide, and scraping off the scale accumulated on the first cavity 110. The flow of cooling water is used to achieve the function of automatic scraping, which has a simple structure and saves energy.

[0025] The descaling tank in this embodiment can accommodate cooling water to be descaled. It can be cylindrical or square, without limitation.

[0026] The scale collecting assembly 200 in this embodiment uses electrochemistry to precipitate and enrich calcium ions on the outer wall of the cathode cylinder 210. It should be noted that the calcium ions in the cooling water can be removed by microbial descaling.

[0036] In one embodiment, the device further comprises at least two limit blocks, which are respectively fixedly disposed at the upper and lower positions of the inner wall of the descaling box 100 to limit the sliding position of the annular sealing plate 310 .

[0037] Compared with the prior art: by adding cooling water to be descaled into the first cavity 110, the volume of the first cavity 110 becomes larger, thereby pushing the annular sealing plate 310 to slide, and scraping off the scale accumulated on the second cavity 120. Similarly, by adding cooling water to be descaled into the second cavity 120, the volume of the second cavity 120 becomes larger, thereby pushing the annular sealing plate 310 to slide, and scraping off the scale accumulated on the first cavity 110. The flow of cooling water is used to realize the function of automatic scraping, with a simple structure and energy saving.
