Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a backwash filter used in a water treatment system. Background Art

[0002] In the prior art, backwash filters are precision devices that use a screen to directly intercept impurities in water, remove suspended solids and particulate matter, reduce turbidity, purify water quality, and reduce system fouling, algae, rust, and other factors, thereby purifying water quality and protecting the normal operation of other system equipment. The electric brush filter is a fully automatic self-cleaning filter. A set of brushes is installed in the filter screen and rotated by a motor. The brushes are installed on the filter end cap with an electric drain valve. During cleaning, a signal from the differential pressure switch is transmitted to the control panel, which opens the drain valve and activates the motor, driving the brushes to rotate and remove dirt and impurities. Under the action of force, the water is discharged from the filter through the drain valve, and cleaning does not require interruption of the flow. This type of filter is widely used in water filtration in power plants, sewage treatment plants, mining, steel, agriculture, municipal administration, chemical industry and other industries. However, in some special working conditions in these industries, such as mining and environmental protection, large amounts of water are mixed with slurry and contain some large particles such as stones. The filter needs to allow the slurry and some fine particles to pass through, while also intercepting these large particles. The filters in the prior art cannot meet these requirements.

[0003] The Chinese utility model patent with application number: 202021719484.2 discloses a backwash filter, comprising a filter housing, a feed port provided on the filter housing, a sewage outlet provided at the bottom of the filter, a filter element vertically arranged in the filter housing, a water inlet main pipe axially arranged in the filter element, a motor provided on the top of the filter housing, and the rotating shaft of the motor is connected to the water inlet main pipe, a plurality of water inlet branches are provided on the water inlet main pipe, and a backwash nozzle is installed on the water inlet branch pipe. However, this type of backwash filter will generate a strong centrifugal force when working, causing the main body of the equipment to shake constantly, affecting the working stability of the backwash filter, and the backwash filter has only one set of water inlet passages, and cannot divert the water body according to the size of the impurities to improve the filtration efficiency of the water body. In the process of flushing impurities, the impurities are easily embedded deeper and tighter in the filter element, causing secondary pollution, and even eventually causing the filter element to be blocked, affecting later use and maintenance.
