Combined type water collecting device of filter

Abstract

The invention discloses a filter combined type water collecting device, which belongs to the field of medium filtration, and comprises a central collecting mother pipe assembly and slit pipe assemblies, the central collecting mother pipe assembly is uniformly provided with a plurality of slit pipe assemblies, and the central collecting mother pipe assembly collects water collected by the plurality of slit pipe assemblies. The central collection mother pipe assembly comprises a central cylinder and a collection pipe; the water collecting device is used for blocking medium filter material loss in the filter and collecting a filtered water source. The gap of the gap pipe is larger than the particle size of the filter material to ensure that the filtered water source can be collected; and in addition, a backwashing water source can be uniformly arranged in the filter material during backwashing, so that different degrees of impact on the filter material during backwashing is avoided, the field occurrence that the surface of the filter material is uneven is avoided, and the backwashing effect is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic self-cleaning filtration, in particular to a filter combined water collecting device. Background technique [0002] At present, in the field of circulating water bypass filtration, media filters are mostly used to filter water bodies.
