Description

Technical Field

[0001] This invention relates to the field of industrial circulating water treatment technology, and more specifically, to a nano-rare earth scale prevention and removal device for industrial water cooling systems. Background Technology

[0002] An industrial water cooling system is a system that uses water as a cooling medium. A water pump delivers cooling water (or a mixed coolant) to the equipment that needs to be cooled. The water absorbs heat and its temperature rises. It then returns to the cooling device (such as a chiller or cooling tower) to cool down, forming a closed or open loop. This process continuously transfers heat and ensures that the equipment temperature remains stable.

[0003] Patent CN118724299B discloses a high-energy treatment device for scale prevention and removal in circulating water, including a shell assembly. The shell assembly includes a heat exchange shell with a first inlet and a first outlet on each side. A first liquid enters through the first inlet and flows out through the first outlet. A second inlet and a second outlet are provided on the front of the heat exchange shell, with a second liquid flowing in through the second inlet and flowing out through the second outlet. This patent, by incorporating a heat exchange assembly and a transmission assembly, facilitates the reduction of liquid flow rate in the first inner tube after scaling, creating a pressure difference between the two ends of the first inner tube. The liquid drives the fan blades to rotate, and the magnet, under the action of an electric current, forms a magnetic field inside the first inner tube. The electromagnetic field is used to achieve scale removal inside the first inner tube, which is beneficial for automatically forming a stable magnetic field inside the circulating water based on the degree of scaling for scale removal.

[0004] Although the aforementioned patented liquid drives the fan blades to rotate, creating a magnetic field inside the first inner tube for descaling, when using nano-rare earth for descaling in industrial water cooling systems, it is necessary to ensure the compatibility of the nano-rare earth powder with the water quality when it enters the circulating water. For example, if the amount of nano-rare earth added at the same time is too small when mixed with high-hardness water, the nano-rare earth particles may be encapsulated by excessive calcium and magnesium ions in the circulating water, thus becoming ineffective. Therefore, it is necessary to ensure a balance between the input of circulating water and nano-rare earth particles.

[0005] In view of this, we propose a nano-rare earth scale prevention and removal device for industrial water cooling systems. Summary of the Invention

The 25 are arranged in a cross pattern, and the first connecting rod 423 and the second connecting rod 425 are rotatably connected to each other at their intersection. An extension column 44 is fixedly connected to the inner side of the connecting pipe 1. Multiple square holes 441 are opened on the surface of the extension column 44.

[0024] Among them, the first material blocking plate 143 and the second material blocking plate 321 are staggered. When the first material blocking plate 143 blocks the screen trough 311, the second material blocking plate 321 does not block the feed trough 312, and vice versa.

[0025] Therefore, when using nano-rare earth for scale prevention and removal in an industrial water cooling system, in the preparation stage, after connecting the feed pipe 141 to the nano-rare earth conveying equipment, the work begins. At this time, the circulating water enters the connecting pipe 1 from the inlet 12 and the dual-shaft motor 171 starts. Driven by the dual-shaft motor 171, the second rotating rod 42 rotates. At the same time, the second rotating rod 42 drives the guide component 41 to rotate together, so that the circulating water flows from the first chamber 21 to the second chamber 22. At the same time, the rotation of the guide component 41 produces a spiral conveying effect. At this time, the circulating water that reaches the second chamber 22 begins to undergo scale prevention and removal treatment. During the spiral water flow, the water passes through the water-blocking plates 332 located on the inner walls of the upper ends of both sides of the connecting pipe 1. The flowing circulating water pushes the water-blocking plates 332 to rotate on the first rotating rod 331, causing the first rotating rod 331 and the circular gear 33 to rotate together. The circular gear 33 meshes with the gear ring 314. As the circular gear 33 rotates, it drives the gear ring 314 and the double-sided conical component 31 to rotate together. During the rotation of the double-sided conical component 31, the screen groove 311 at its top gradually moves away from the first material-blocking plate 143 blocking the screen groove 311, creating an opening at the top of the screen groove 311. Simultaneously, the second material-blocking plate 321 gradually rotates to the position of the discharge trough 312 until the screen groove 311 is fully open and the discharge trough 312 is fully closed. At this point, when the nano-rare earth falls to the top position of the double-sided conical component 31, the nano-rare earth will gradually fall from the screen groove 311. The nano-rare earth is stored in the closed feeding trough 312. When the circular gear 33 drives the gear ring 314 to rotate continuously, the feeding trough 312 and the screen trough 311 will reciprocate and open and close. At this time, the nano-rare earth falling inside will also fall in stages, forming an intermittent conveying effect of nano-rare earth. When the water flow increases, the rotation speed of the circular gear 33 and the gear ring 314 will increase, and the rotation speed of the double-sided conical part 31 will also increase. At this time, the opening and closing rate of the feeding trough 312 and the screen trough 311 will increase, and the falling nano-rare earth will be more sparse and frequent. Considering that high hardness water needs to be protected from being coated with excessive calcium and magnesium ions during the flow process, low-frequency nano-rare earth is added during the slow flow of circulating water to give the circulating water enough time to coat calcium and magnesium ions. The same applies to the opposite. This realizes the ability to change the conveying amount of nano-rare earth according to the water flow size, thereby controlling the scale prevention and removal of circulating water. After the nano-rare earth enters the second chamber 22 and comes into contact with the circulating water, the rotation of the second rotating rod 42 will drive the stirring rod 43 to rotate together, mixing the nano-rare earth with the circulating water and flowing into the third chamber 23. During this process, after being coated by calcium and magnesium ions, a relatively heavy granular mixed soft scale is formed in the circulating water. At this time, the mixed soft scale will gradually fall down after being transported. Part of it falls into the square hole 441 at the top of the extension column 44, while the rest falls into the inner wall of the connecting pipe 1. At this time, the mixed soft scale needs to be treated. During the rotation of the second rotating rod 42, the reciprocating screw 421 will also rotate. While the reciprocating screw 421 rotates, it will cause the sliding ring 424 on one end to slide left and right. When the sliding ring 424 slides towards the fixed ring 422, it will cause the first connecting rod 423 and the second connecting rod 425 to retract inward and extend the extension plate 442 outward until it reaches the outermost position of the square hole 441, so that the extension column 44 is completely closed. Conversely, it will cause the first connecting rod 423 and the second connecting rod 425 to unfold and cause the extension plate 442 to retract inward in the square hole 441. This process is repeated, so that the mixed soft scale will not fall down immediately after it is formed, but will be pushed to the outside of the extension column 44 by the extension plate 442 and gradually slide into the collection box 15, which will then be removed by the staff for cleaning. After descaling in chamber 3 23, the circulating water is filtered through filter screen 45 and flows to chamber 4 24 and out through outlet 13.
