Rotating negative electrode scale scraping and removing device

Abstract

The invention relates to a rotating negative electrode scale scraping and removing device which comprises negative electrode conductive columns 1, negative electrode plates 2, a rotating shaft 6, positive electrode plates 7 and scrapers 8. The negative electrode conductive columns 1 are closely attached to the negative electrode plates 2. The negative electrode conductive columns 1, the negative electrode plates 2, the scrapers 8 and the positive electrode plates 7 are sequentially connected to the rotating shaft 6 in series. A central limiting and correcting block 3 is arranged between the scrapers 8 and the positive electrode plates 7. The negative electrode plates 2 rotate around the rotating shaft 6. A jackscrew 4 is arranged on one side of each negative electrode conductive column 1. Currents are guided into the negative electrode plates 2 by the negative electrode conductive columns 1. In the rotating process of the negative electrode plates 2, the scrapers 8 are closely attached to and scrap the surfaces of the negative electrode plates 2. The purpose of inputting currents to the rotating negative electrode plates without electric brushes is achieved, electrode intervals are easily decreased to the maximum degree, and the scale scraping and removing effects of the negative electrode plates are improved.

Description

technical field [0001] The invention belongs to the technical field of industrial water treatment, in particular to a rotary cathode scraping and descaling device. Background technique [0002] Electrochemical water treatment technology is a scale control technology that has attracted more and more attention recently, and more and more diverse electrochemical water treatment devices have been developed, but the electrochemical water treatment devices that have been put into practical use generally have complex structures. 1. The descaling effect is not good, the scale on the surface of the pole plate is not easy to be scraped off, and it is easy to generate hard scale on the scaled surface, etc. The setting of the distance between the pole plates is also greatly restricted.

[0002] Electrochemical water treatment technology is a scale control technology that has attracted more and more attention recently, and more and more diverse electrochemical water treatment devices have been developed, but the electrochemical water treatment devices that have been put into practical use generally have complex structures. , The descaling effect is not good, the scale on the surface of the plate is not easy to be scraped off, and hard scale is easy to form on the scaled surface, etc. The setting of the distance between the plates is also greatly restricted

[0003] In the field of electrochemical water treatment, electric brushes have been well used as good conductive parts. However, due to the continuous rotation of the cathode plate in the scraping and descaling device, the brushes often appear to be in poor contact or even disconnected. How to ensure the normal operation of the cathode plate and input current to the rotating cathode plate when the brush is abnormal or there is no brush has become an urgent problem to be solved
