Description

Technical Field

[0001] The utility model relates to the technical field of circulating water purification, in particular to a circulating water composite electro-adsorption scale removal device. Background Art

[0002] During the production operation process, a circulating water system is often required for cooling. In the long-term circulation process of the cooling water in the circulating water system, scale and bacteria are likely to be generated. The background technology of the circulating water composite electro-adsorption scale removal device stems from a profound understanding of the problems such as scaling, corrosion, and microbial contamination faced in the long-term operation of industrial circulating water systems. Traditional circulating water treatment methods often rely on the addition of chemical agents, which not only increases the operating cost but also may cause secondary pollution to the environment. With the improvement of environmental awareness and the increasing demand for energy conservation and consumption reduction, it is particularly important to develop a highly efficient and energy-saving circulating water treatment technology. In this context, the composite electro-adsorption scale removal device came into being.

[0003] In a box-type composite electro-adsorption device with the publication number of CN221027859U, it includes a box reactor connected to the circulating water system; the cooling water in the circulating water system can conduct electricity; an adsorption chamber and a slag collection chamber are arranged in the box reactor, and the slag collection chamber is arranged directly below the adsorption chamber and communicated with it; a cathode plate and an anode plate are inserted into the adsorption chamber, and the cathode plate and the anode plate are respectively electrically connected to the negative and positive poles of a DC power supply; a scale scraping device is arranged at the cathode plate, and the scale scraping device is used to remove the scale adsorbed on the cathode plate; a screw conveyor is arranged in the slag collection chamber, and the slag discharge port of the slag collection chamber is arranged at the output end of the screw conveyor. This solution uses the method of electrolyzing cooling water to achieve scale removal and scale inhibition of cooling water, and strong oxidizing substances such as hypochlorous acid generated by electrolysis can inhibit the growth of bacteria and algae, and can partially replace chemical agents, with high economic and environmental benefits.

[0004] When the above-mentioned prior art is used, it mainly uses the cooperation of the cathode plate and the anode plate to remove scale from the circulating water. However, in the actual use process, since the cathode plate and the anode plate are fixedly arranged, during the treatment process of the system circulating water, it needs to automatically circulate in the treatment tank for scale removal. Lack of corresponding stirring design results in uneven water flow velocity. Further, scale-forming substances such as calcium and magnesium ions near the electrode plate or the treatment area are preferentially removed, while those far from these areas may accumulate and continue to form new scale, resulting in poor overall scale removal uniformity and affecting the overall scale removal efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a circulating water composite electro-adsorption scale removal device to solve the problem that the existing circulating water composite electro-adsorption scale removal device lacks water flow stirring during use, resulting in uneven scale removal effect of the circulating liquid and low efficiency, as mentioned in the above background art.

There are two groups of connecting pipes 11 connected between the slag discharge tank 1 and the adsorption scale removal tank 2, and solenoid valves are arranged on the connecting pipes 11. It also includes: a multi-axis linkage mechanism 5 is arranged on the top of the adsorption scale removal tank 2. The multi-axis linkage mechanism 5 includes a main motor 501, and the main motor 501 is arranged on the top of the adsorption scale removal tank 2. One end of the main motor 501 is connected to a main rotating shaft 502. The two ends of the outer side of the main rotating shaft 502 are respectively sleeved with a first belt assembly 505 and a second belt assembly 506 from left to right. One end of the first belt assembly 505 is connected to a linkage shaft 503, and one end of the second belt assembly 506 is connected to a driven shaft 504. One ends of the linkage shaft 503 and the driven shaft 504 both extend into the adsorption scale removal tank 2. The first belt assembly 505 and the second belt assembly 506 both include a set of driving wheels, a set of driven wheels and a set of linkage belts. The driving wheels are all sleeved on the main rotating shaft 502, the driven wheels are respectively sleeved on the outer sides of the linkage shaft 503 and the driven shaft 504, and the driving wheels and the driven wheels are connected with linkage belts between them.
