Description

Technical Field

[0001] The utility model relates to the technical field of sand filtration equipment, in particular to a sand filtration equipment for treating waste water in liquid crystal product production. Background Art

[0002] The sand filtration equipment for treating waste water in liquid crystal product production, usually called sand and gravel filter or quartz sand filter (sand filter), is an important equipment for filtering organic and inorganic impurities in water. Using sand and gravel as filter media, it has a strong ability to intercept dirt, a very strong ability to filter out and retain impurities, and can supply water continuously.

[0003] The water to be filtered reaches the media layer through the water inlet. Most pollutants are intercepted on the surface of the media, and fine dirt and other floating organic matters are intercepted inside the media layer. When the impurities and various suspended matters in the water reach a certain amount, the filtration system can detect the pressure difference between the inlet and outlet in real time through the pressure difference control device and automatically carry out the sewage discharge process.

[0004] However, when discharging sewage, the media layer needs to be cleaned. However, during cleaning, the filtration work needs to be suspended for a long time and can only resume after the cleaning is completed, which affects the work progress. Therefore, a sand filtration equipment for treating waste water in liquid crystal product production is proposed. Content of the Utility Model
