Example Embodiment

[0019] The present invention will be further described below in conjunction with the embodiments shown in the drawings. A) Structure:

[0020] This vessel is a cylindrical steel structure pressure vessel. It is mainly composed of a base, a filter, a rotating mud pipe system, and a housing. The base 23 is supported by three supporting feet 18. The base 23 is surrounded by upper and lower bottom plates. The outer space is the water purification catchment area and the water outlet, and there is a water inlet pipe 14 passing through it; the inner circle is the water inlet and water distribution area; the center is occupied by the rotating mud discharge main pipe 8. A number of pipe holes are opened in the upper bottom plate, which are connected with the water collection branch pipe 35 of each filter. The filter plate is composed of filter material 3, frame 5 (pipe frame with small holes for collecting water), and water collecting branch pipe 35. The filter is a circular arc upri...

Abstract

The invention belongs to the technical field of water treatment and relates to a swimming pool water filtration device. The swimming pool water filtration device comprises a water inlet pump, a housing, filter sheets, a rotation sludge-discharge device, a water distribution system, a water collection system and other accessories. The swimming pool water filtration device utilizes a light nontoxic extension-type ordered braided fabric as a filter material. The filter sheets have shrink ring-type cylinder structures. The swimming pool water filtration device utilizes a rotation line-type sweep washing method to carry out backwashing. The swimming pool water filtration device has the advantages of large effective filtration area, no storage of washing water, good product water quality, large filtration flow amount, small pressure-type loss, low power consumption, no daily concierge management, and assembling-disassembling and maintenance convenience. The swimming pool water filtration device can be widely used for treatment on water and other fluids, and especially for recycle of swimming pool water, purification of recirculated cooling water, treatment on agricultural irrigation water, and detection and treatment on low-turbidity high-quality raw water.

Description

technical field [0001] The invention belongs to the technical field of water treatment (it can also be applied to similar fluids), and in particular relates to a swimming pool water filtering device. Background technique [0002] In water filtration equipment, there are generally two types of gravity and pressure filtration, and the filter materials are mostly dispersed particles such as quartz sand, anthracite, and diatomaceous earth. Quartz sand filtration: lay a quartz sand layer in the pressure tank, the thickness is about 900-1200 mm, and the particle size of the filter material is 0.4-0.6 mm. The filtration speed of quartz sand is usually 20-30 m 3 / (m 2 h), the turbidity of the effluent is 0.5 NTU. The quartz sand filter takes a long time to backwash (about 10 minutes) and consumes a lot of water (the backwashing intensity is 15 liters / second per square meter). The reason is that the pollutants in the water adhere to the surface of the sand particles, and the fric...
