Description

Technical Field

[0001] The present application relates to the field of circulating water treatment, and in particular to a scale inhibition device for circulating water treatment of a cooling tower. Background Art

[0002] In a cooling water circulation device, non-water-soluble calcium salts (scale) will adhere to the inner wall of the pipe. As the scale increases, they will cause the pipe to become blocked or the cooling efficiency to decrease. At present, the existing method of descaling is to use chemical reagents, that is, adding specially formulated chemical agents to the cooling water, and then the chemical agents and the hard scale condensed on the equipment react chemically to dissolve, loosen, fall off or peel off the scale in the cleaned equipment.

[0003] Announcement No. CN211688500U discloses a cooling tower circulating water scale prevention device. The new type can filter the impurities in the circulating water more cleanly by filtering the circulating water multiple times, and it is easy to clean and replace the cleaning filter device, which greatly improves the purification efficiency and purification quality of the circulating water and is more convenient to use.

[0004] However, there are some defects in the above scheme: in the above scheme, multiple filter elements and cleaning rings that can clean the surface of the filter element are set, but the impurity ditches filtered out are mostly inside the filter element, and the method of cleaning the outer surface cannot effectively clean the blocked impurities, and most of the impurities and scale after cleaning remain in the filter bin, and even enter the next filter element along the water pipe, which will still cause the filter element to be blocked and the filtering effect is poor, and it is necessary to disassemble and clean the debris and impurities later.

[0034] One end of the box body 110 is connected to a water inlet pipe 111, and the other end of the box body 110 is connected to a water outlet pipe 112. The water inlet pipe 111 and the water outlet pipe 112 are provided to connect to a circulating water pipe of a cooling tower.

[0035] Specifically, the filter group 120 includes a first filter 121, a second filter 122 and a third filter 123. The first filter 121, the second filter 122 and the third filter 123 are all located at the bottom of the cover plate 130. By arranging the first filter 121, the second filter 122 and the third filter 123, the multi-stage filter can fully filter the circulating water connected to the cooling tower. The first filter 121 is a PP surface filter, the second filter 122 is a US composite filter, and the third filter 123 is an activated carbon filter.

[0036] Among them, a groove plate 131 is set at the bottom of the cover plate 130, and the first filter screen 121, the second filter screen 122 and the third filter screen 123 are all provided with a T-shaped block 124, and the T-shaped block 124 is slidably inserted in the groove plate 131. By setting the T-shaped block 124 and the groove plate 131 to be slidably inserted, it is convenient to pull out and disassemble.

[0037] It should be noted that a limit plate 140 is provided on the inner wall of the box body 110, and the first filter screen 121, the second filter screen 122 and the third filter screen 123 are all slidably inserted into the limit plate 140. The limit plate 140 is provided to limit the position of the filter screen after being inserted into the box body 110 and maintain stability.

[0038] See also Figure 1 , 2 , 3 and 5, the cleaning assembly 200 includes a movable frame 210, a cleaning plate 220 and a slag discharge pipe 240, the movable frame 210 slides through the cover plate 130, the cleaning plate 220 is arranged at the bottom end of the movable frame 210 and contacts the filter mesh group 120, and the slag discharge pipe 240 is connected and arranged at the bottom of the box body 110.

[0039] Among them, the movable frame 210 includes a sliding rod 211 and a cross bar 212. The sliding rod 211 slides through the cover plate 130 and is fixedly connected to the cleaning plate 220. The cross bar 212 is fixedly connected to the sliding rod 211. By setting the sliding rod 211 and the cross bar 212, the cross bar 212 is pulled, and the cross bar 212 drives multiple sliding rods 211 to move synchronously.

When cleaning impurities on the filter screen, pull the cross bar 212, the cross bar 212 drives multiple slide bars 211 to move synchronously, the slide bar 211 drives the cleaning plate 220 to move, and the cleaning plate 220 cleans the blockage Impurities in the filter mesh holes, and cleaning plates 220 are arranged on both sides of the filter mesh, which can effectively clean the impurities blocking the filter mesh holes and ensure the filtering effect of the filter mesh. After using it for a period of time, the valve on the slag discharge pipe 240 can be opened to discharge the filter residue impurities to avoid clogging the filter mesh again. There is no need to frequently disassemble and clean the debris and impurities. When the filter mesh needs to be replaced, the electric telescopic rod 150 is started to push the cover plate 130 to move up, and the cover plate 130 drives the entire filter mesh group 120 to move up, and then each filter mesh is removed by pulling, and then it can be replaced, which improves the disassembly and assembly efficiency.

[0043] It should be noted that the specific model and specifications of the electric telescopic rod 150 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
