Problems solved by technology
Shaft water intake technology is especially suitable for sea water intake with high turbidity and poor water quality near the coast. However, general water intake shafts have high requirements for the geological structure of the water intake area and are not suitable for muddy geological structures.

Abstract
The invention discloses a seawater self-cleaning filter device and method, which comprises an outer sleeve with open upper and lower ends, a first filter cartridge with an open upper end, an annular second filter cartridge connected with the outer peripheral surface of the first filter cartridge, and a second filter cartridge connected with the first filter cartridge. A sealing cover plate connected to the second filter cartridge and a circulation cleaning structure connected to the second filter cartridge; a water intake pipe is arranged on the sealing cover plate, and a support frame is provided between the first filter cartridge and the second filter cartridge, The first filter cartridge includes an outer net cylinder and an inner net cylinder, the first grit is filled between the outer net cylinder and the inner net cylinder, and the second gravel is filled between the second filter cartridge and the outer net cylinder; the circulation cleaning structure includes the second A return pipe connected to the filter cartridge, a stirring structure arranged in the return pipe and several flushing nozzles arranged on one side of the return pipe. The invention has the characteristics that it can be cleaned automatically and is suitable for use on beaches with various geological structures.
Description
technical field [0001] The invention relates to the technical field of seawater intake shafts, in particular to a seawater self-cleaning filter device and method suitable for beaches with various geological structures. Background technique [0002] Of the total water resources on earth, fresh water accounts for only 2.5%, while seawater accounts for 97.5%. Seawater utilization is one of the important measures to solve the water resource crisis in our country. However, some of the seawater near the coast of my country has high silt content and the seawater is turbid. The use of seawater needs to remove the silt first. [0003] At present, the commonly used method of removing sediment in seawater is to settle in a sedimentation tank, which has the problems of large area, long time consumption and low efficiency. [0004] Shaft water intake is to build a certain depth of shaft near the sea or even on the beach. It is constructed with permeable well wall materials. This techno...
