Abstract
Description
Technical Field
[0001] This invention relates to the field of circulating water purification technology, and in particular to a circulating water purification and reuse system. Background Technology
[0002] During the production of cold-rolled steel, after the steel strip is heated in an annealing furnace to relieve stress, some oxidation will occur on the surface, requiring pickling. Before pickling, the steel strip needs to be cooled to below 50 degrees Celsius. In order to accelerate the cooling of the steel strip, a cooling system needs to be provided for the annealing furnace to cool the steel processed in the annealing furnace.
[0003] The invention disclosed in the existing patent announcement number CN221107373U is a circulating water purification and reuse system for the cooling section of an annealing furnace, including a cooling tower, a sedimentation tank, a fan, and an electrostatic precipitator. The outlet of the cooling tower is connected to a pressure pump, the pressure pump is connected to a pressure water pipe, the left end of the pressure water pipe is connected to a mist cooling box, and the surface of the pressure water pipe is provided with a spray nozzle and a mist spray nozzle. The inlet of the sedimentation tank is connected to the mist cooling box, the outlet of the sedimentation tank is connected to a water storage tank, the outlet of the water storage tank is connected to a filter, the filter is connected to the cooling tower, and the exhaust port of the electrostatic precipitator is connected to a spray tower.
[0004] Using the above technical solution, large particulate impurities in the water can be precipitated in the sedimentation tank. The precipitated large particles are discharged into the sewage tank for further treatment. The precipitated water is then purified by a filter and then enters the cooling tower for reuse. The cooling tower lowers the water temperature to ensure that the water entering the mist cooling box is always low-temperature water, resulting in a more stable cooling effect. However, there are still some problems with the above solution. First, the removal of solid particles in the cooling water is accomplished by sedimentation, which has a poor removal effect and low speed and efficiency. Furthermore, some solid particle removal equipment on the market uses a single filtration method, which cannot effectively remove solid particles, easily leading to increased time and economic costs and causing inconvenience to users.

[0035] In this embodiment, as a preferred solution, the rebound structure 5 includes a mounting plate 51, a drive motor 52, a rebound rod 53, a limiting block 54, and a spring rod 55.

The two ends of the blocking rod 41 are slidably connected to the symmetrically arranged limiting member 42.
[0039] In this invention, during use, the valve above the inlet pipe 3 is opened to release the waste cooling water. After the water flows through the movable filter assembly 2 for a period of time, the valve above the inlet pipe 3 is closed, and the waste cooling water stops entering. At this time, the electrical components inside the purification housing 1 are activated. First, the drive motor 3 92 is started, which quickly drives the ejector rod 93, pushing the movable filter assembly 2 to rotate. As the movable filter assembly 2 rotates, the filter frame 24 first collides with the blocking structure 4 and is blocked from moving forward. At this time, the filter frame 1 21 and the filter frame 24 are rotatably connected. The filter frame 1 21 is not affected by the blocking effect and continues to rotate along the rotating shaft 2 until it collides with the return rod 53, pushing... The rebound structure 5 moves downward. When the rebound structure 5 moves downward to a suitable position, it triggers pressure sensor 1. At this time, the angle adjustment structure 7 is activated, and drive motor 2 72 starts to drive drive motor 1 52 to rotate. When it rotates to a suitable position, it triggers pressure sensor 2. At this time, the rebound structure 5 starts, and drive motor 1 52 starts, quickly pushing the rebound rod 53, so that the entire movable filter assembly 2 rotates counterclockwise to reset to the initial position. At this time, the valve above the water inlet pipe 3 is opened, and water flows through the infrared sensor. At this time, the activation of the ejection structure 9 is cut off, and the cooling water is filtered.
