Description

Technical Field

[0001] The invention relates to the technical field of water quality control, and in particular to a thickener top overflow water quality control device and a control method thereof. Background Art

[0002] A thickener is a solid-liquid separation equipment based on gravity sedimentation. It uses gravity to settle solid particles in the slurry to achieve solid-liquid separation. It is usually built with concrete, wood or metal welded plates and other materials into a cylindrical shallow trough with a conical bottom. A slow-running rake is installed inside to push the thickened underflow slurry. Thickeners are widely used in hydrometallurgy, mineral processing plants and chemical plants to treat ore mud, wastewater and waste residue. They can concentrate slurry with low solid content into underflow slurry with high solid content. With the continuous advancement of technology, thickeners are also constantly innovating, such as high-efficiency transformation and the application of new transmission methods, in order to improve the concentration efficiency and blowing capacity, and thickeners are widely used in hydrometallurgy, mineral processing plants and chemical plants to treat ore mud, wastewater and waste residue. The thickener is an important ore processing equipment, playing an irreplaceable role in improving ore purity and subsequent processing efficiency. Its technology and application are also constantly developing and improving. As a solid-liquid separation equipment, the thickener always produces a large amount of overflow water during the processing process. In order to save water resources and reduce environmental pollution, it is particularly important to regulate the overflow water quality at the top of the thickener. The overflow water system at the top of the thickener mainly includes a sedimentation tank, a water pump and a filter cartridge. The overflow water quality is improved by adding a filter cartridge and a filter screen. At the same time, the design of the sealing plate and the scraper is used to scrape off the filter residue left on the filter screen to ensure that the water is smoothly pumped to the high-level water pool and save electricity. Traditional thickener overflow water systems may have problems with filter residue residue and power waste. Air mixed in the slurry, too high mud content, too large a processing volume or improper underflow control will cause the thickener to be unable to effectively separate solids and liquids, making the overflow water turbid. During the operation of the thickener, there will be deviations in the verticality of the thickener center column, deviations in the horizontality of the drive device, and the rakes are not at the same level. These problems will cause the thickener to deviate during operation, which will cause abnormal vibration and abnormal noise, and long-term operation will cause damage to the equipment.
