Description

High self-cleaning rate automatic filter

Technical Field

The utility model relates to an automatic filter with high self-cleaning rate, which is mainly used for removing foreign matters, fragments and impurities of industrial circulating water, belonging to the technical field of water filtering equipment used in industrial circulating water supply systems, and is widely applicable to industries of ceramics, electric power, heating power, mining industry, plastics, chemical industry, rubber, pharmacy, food, environmental protection, pigment, dye, electronics, metallurgy and the like.

Background

The water filter is widely applied to circulating water supply systems in various industries such as ceramics, electric power, heat, mining industry, plastics, chemical industry, rubber, pharmacy, food, environmental protection, pigment, dye, electronics, metallurgy and the like, the water source is generally directly obtained from a river, and sediment and suspended matters such as sediment, weed, household garbage, construction garbage and the like are contained in the water. At present, a full-automatic water filter is generally adopted for separating dirt in water, and the common problem is that dirt and impurities cannot be discharged out of the water filter, so that the inside is blocked, even a filter screen and a pollution discharge mechanism are deformed and damaged, and frequent shutdown repair is required.

The industrial water supply filters commonly used at present are divided into four types of centrifugal filters, sand-stone filters, screen filters and stacked filters. Sand filters, which are mainly used for the front-stage filtration of organic matter in open water sources, and centrifugal filters, which are not capable of removing impurities such as organic matter close to the specific gravity of water and lighter than water, are not very high in precision because they are manufactured with low technical content and usually need to be combined with other types of filters for reprocessing. The lamination type filter has the advantages of small water flow resistance and low operation cost, but has the technical problem of cleaning work. The screen filter has the advantages of simple structure, low cost, good filtering effect, wide application and the like, but the traditional screen filter in China has the defects of poor tightness, high failure rate, poor anti-interference performance, high equipment manufacturing cost, high power consumption, poor backwashing capability and the like in structure and control. In addition, in a general filtering device, as the filtering process is continued, the back cleaning and the decontamination are not thorough, the solid impurities in the circulating water are trapped on the surface of the filter screen core to gradually increase, so that the pressure drop of the circulating water passing through the filter screen is increased, the filtering resistance is increased, and the filtering efficiency is reduced. In this case, the filtering operation is generally interrupted, and the filter screen core is replaced or taken out for cleaning, which is time-consuming and labor-consuming and affects the treatment efficiency.
