Inclined mesh panel type filtering apparatus

Abstract

An inclined mesh panel type filtering apparatus capable of easily removing suspended solids from water. In a conventional apparatus, a filtration fabric is contaminated from use even when it is cleaned by a brush unit or a cleaning unit, and is almost clogged, in the course of one to two years after being put into operation, to such an extent that scale is not even removed even by additional manual cleaning. Thus, the entire apparatus should be disassembled to replace the filtration fabric with a new one or exchange an entire filter drum. This problem is resolved by the inclined mesh panel type filtering apparatus that can be continuously operated for a long time in which a filtration panel formed with fine openings having a typical size of 0.2 to 1.2 mm is not clogged and does not require high-pressure cleaning-water or air showers that consume high energy.

Description

technical field [0001] The present invention generally relates to a filter device used in a water treatment process, and more particularly, to an inclined screen type filter device for removing suspended matter contained in water to improve efficiency in a sewage / wastewater or water treatment process prior to a main treatment process . Background technique [0002] Generally, in a sewage treatment plant, in order to prevent the machinery of the main treatment process from being damaged due to the inflow of coarse debris, a coarse screen with a gap of 50 to 100 mm or a fine screen with a gap of 20 to 40 mm is installed in the inflow path. screen. [0003] In addition, in order to prevent fines that cannot be caught by the coarse screen or fine screen from entering and adhering to each part of the water tank of the treatment plant in a suspended state or subsequently accumulating to block the pump or valve, a 2 to 10 mm Slotted ultrafine sieve. [0004] However, with the in...

Problems solved by technology

The membrane separation process has the problem that the membrane needs to be replaced frequently since the membrane is easily contaminated and clogged by fines such as hair that can pass even through a narrow groove of 2 to 3 mm in width

[0009] Among them, since the sieve drum according to Patent Document 5 is made of a circular or slit-shaped perforated plate with a diameter of 2 to 10 mm, the sieve cannot catch fines having a particle size of 0.2 to 1.2 mm, and since the sieve according to Patent Document 5 In the screen of Document 6, a plurality of annular sheets are arranged and assembled to have regular grooves of about 5 to 10 mm to form a screen drum, and the annular grooves of the screen drum are scraped and cleaned by a comb rake, so the screen cannot Captures fines with a particle size of 0.2 to 1.2mm
