Composite electret fiber filter

Abstract

The invention belongs to the technical field of water treatment equipment, and particularly relates to a composite electret fiber filter, which comprises a tank body, a motor, a controller, a water inlet hole, a water outlet hole and filter fiber balls, wherein an axial adjusting module, an axial adjusting fixing frame and a radial adjusting fixing frame are arranged on the inner side of the tank body, the radial adjusting fixing frame comprises fixing rings and arc-shaped sliding blocks, at least three pairs of arc-shaped sliding blocks are arranged between the connecting positions of the fixing rings, the arc-shaped sliding blocks are connected to the fixing rings in a sliding mode, a fixing net is arranged in the fixing ring, and the filter fiber balls are fixedly mounted at the nodes of the fixed net. In the prior art, the position of a single filter fiber ball is not limited, so that the filtering effect cannot be adjusted. According to the invention, the device is simple in structure, the fiber filter balls can be orderly arranged in the tank body, are convenient to check and replace and are not easy to lose, and the density of the filter fiber balls is adjusted in real time according to the water quality, so that the filtering efficiency is improved under the condition of ensuring the filtering effect.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, in particular to a composite electret fiber filter. Background technique [0002] Fiber filters are widely used in electric power, chemical industry, papermaking, metallurgy, printing and dyeing, urban water supply and other industries: industrial water supply system, domestic water supply system, heating network return water system, circulating cooling water system, bathing water circulation treatment system and the depth of water resources Treatment pretreatment, reclaimed water reuse, etc. One of them is a fiber ball filter that uses fiber balls as the filter material. The fiber balls have a large specific surface area and porosity to absorb and trap suspended particles in the water at the same time, giving full play to the deep pollution interception ability of the filter material; the fiber balls are not easy to be stained with oil. Therefore, backwashing is relatively eas...

Problems solved by technology

[0004] In this solution, the cleaning of the filter fiber balls is improved to a certain extent, but the filter fiber balls are not fixed, so they are in a free state, and the gap between the filter fiber balls is difficult to control, so it is impossible to adjust the distance between the filter fiber balls according to the water quality. When there is a lot of dirt in the water, frequent backwashing is required to remove the dirt trapped on the filter fiber balls. At this time, the filter fiber balls tend to flow out with the dirt and block the filter baffle, and even damage and flow out of the tank, thereby affecting Filtration effect; on the other hand, the filter fiber balls are piled up together, it is difficult to distinguish good from bad, and it is not easy to replace them in a targeted manner; when the water is less dirty, the arrangement of the filter fiber balls remains unchanged, and the water flow efficiency and water quality The time difference is not much different, which affects the filtration efficiency and the head loss is also large
