Description
Technical field
Utility model is that the improvement with the revolution fine fack is filtered in water treatment, and it is big to relate in particular to a kind of identical screen area effective filtration area and filtration flux, and the water treatment that filtration flux can not filtered the irrigation canals and ditches width limitations is with turning round fine fack.
Background technology
The swinging grid is an important solid-liquid separating equipment in the water treatment operation; Especially fine fack is used to separate some impurity that can not effectively remove through deposition of removal; Fiber for example, silk such as hair, line class and other fine particle impurity have irreplaceable effect in sewage treatment process; For example be used for the water outlet of sewage disposal second pond, get into the ultrafiltration before film is handled.The prior art rotary grid; For example Chinese patent CN2267238, CN2390868, CN2520327, CN201099626, CN201031150, CN201834775, CN101721849A, CN201200832, CN201834775U etc. are said; Basic composition is by frame; Plane rotation grid that the machine of being arranged on adds (the grizzly bar form has multiple, for example grid type, wedge shape net, mesh grid, punching net sheet radial type etc.) and revolution drive, and four parts such as deslagging are formed.Filtering type of service is to meet water placement (vertical or the approximate vertical or the angle that tilts) in water channel by the rotary grid face, and the formation filtered water is met and gone out the single face filtration after the revolution filtering surface advances.Filtering grid facial plane form and the grid face single face that meets water filters and never to be broken; Not only the dative grid width is proportional to cause the flat screen filtration flux, and is placed water channel width restriction (filtering net surface meet water filtering grid be vertical or be inclined in the water channel with the width face).The main deficiency of this rotary grid is: filtering surface plane, and the filtering surface filtration that meets water can only be that single face filters, half the (be to the maximum and be positioned over single face area under water) of the also not enough revolution filter screen of effective filtration area maximum; The filtering net surface filtration that meets water, filtration flux can only rely on the filter screen face width to increase and realize, restricted by the water channel width but filter face width; Be that filtration flux also is subject to filtration irrigation canals and ditches width, increase filtration flux and must increase the water channel width, cause civil engineering cost to increase with taking up an area of; Some old Sewage Plant particularly, second pond water outlet width of the channel degree is fixed relative narrower; Being difficult to increases, thereby is unfavorable for existing water processing establishment transformation; Besides, filtering net surface meets water and flows through filter interception dirt, and the dirt that is trapped (particularly silk such as fiber, hair, line class impurity) receives effect of water pressure to be prone to stick the grid filtration wire side; Not only can take to and filter the downstream water body, get into follow-up sewage disposal operation, or stop up the subsequent handling treatment facility with 360 ° of revolutions of grid rotation; Or discharge with tail water; Reduce treatment effect, and adhere to very difficult the dashing through water of wire side and remove, long time integration adheres to can cause the filter screen obstruction; Filtration flux is descended, and is very much troublesome in the engineering.Though prior art people improve rotary grid in a large number, mostly concentrate on the improvement of grizzly bar or grid sheet or device for revolving and driving or removal of impurities, wire side remains planar structure; Filter type also still is the wire side filtration that meets water; Any improvement is not arranged, cause above-mentioned inherent defect effectively not solved for a long time, people also want to solve; But can not former cell structure of tripping and occupation mode, so have failed breakthrough based on the mode of thinking.
Barrate type grilling trash removers such as Chinese patent CN2581501, CN201534024U, CN201445850U, CN201433115; Adopt the rotary drum filter screen; Though changed the filter type that meets water, impurity trapped and downstream are isolated, can play preventing to bring the downstream water body into by the grid rotation.But; Because cylindrical shape filtration pattern and tilting are installed; Make same widths filter the irrigation canals and ditches effective filtration area and greatly reduce than rotary grid, thereby filtration flux is stronger to channel width dependency, identical filtration yield needs the wideer filtration irrigation canals and ditches and the drum-type grid of larger diameter; In addition, Barrate type grilling operation inclination installation needs the high strength bearings, and is higher to the installation and operation maintenance requirement of equipment.
The above-mentioned two types of rotary grid filters of prior art are not enough jointly, filter all only to flood single face in the water, and filtration flux all are subject to and filter the irrigation canals and ditches width, and this two big inherent defect still fails effectively to be solved for a long time, is restricting the efficient application of rotary grid.
Above-mentioned deficiency still has is worth improved place.
