Water inlet is connected with the rectification water inlet pipe sub-assembly, and the rectification water inlet pipe sub-assembly is set with the ultra dense film grid, institute
The transmission device linkage impurity fiber remove device is stated, the particulate matters such as impurity fiber are automatically drained out by transmission device, it is described
Automatic back-washing cleaning device is located inside close film grid filtration device, the ultra dense film grid of timing automatic cleaning, is easy to safeguard, more has
The particulate matters such as the discharge impurity fiber of effect.
Further, the water inlet is arranged on the top of ultra dense film grid filtration device, and the delivery port is arranged on super
The bottom of close film grid filtration device, the delivery port export for circular arc type, using circular arc type design structure, so as to which water outlet uses
Flow by gravity, by the self gravitation of flowing water in filter as mobilization dynamic, so as to save operating cost.
Further, the rectification water inlet pipe sub-assembly crosses the form of water using overflow, and rectification water inlet pipe sub-assembly can be with
The current of steady water, reduce the turbulence level of current, overflow cross water serve water filtration in future be uniformly distributed in it is whole ultra dense
Film grid, further improve filter effect and reduce local assault load of the current to ultra dense film grid simultaneously.Double water outlets are designed with
Effect increase filter area, while greatly increase filtering traffic.
Further, the ultra dense film grid is tubular, and the spacing of grid is 80 μm~200 μm.The ultra dense film grid
Filtering sheet material be spaced in inverted triangle arc, fluid by when solids and grizzly bar contact surface it is small, even if having small
Particulate matter by, due to grizzly bar rear portion gap it is wider and easily by so whole ultra dense film grid is not easy to form blocking and had
There is higher dehydrating effect, the ultra dense film grid of tubular uses 360 ° of tubular type moulding, and automatic rotation is connected with transmission device, was improved
Filter effect simultaneously and increase filter area.
Further, the back of the ultra dense film grid is provided with reinforcement.
Further, the shell is trapezoidal for side, and the filter and its all parts use 304 or 316 stainless steels
And equal material.
The utility model is installed on every profession and trade Waste Water Treatment compared with traditional swinging grid, ultra dense film grid filtration
Device grid spacing is small, and typically at 80 μm~200 μm, processing accuracy has the raising of matter, can remove fine particle, slurry, thin
The impurity such as small fiber, cotton-wool body, it can be applied to the pre-treatment link of the membrane filtrations such as MBR, ultrafiltration；Water side is crossed using gravity
The impurity such as formula, fine particle, fiber, cotton-wool body under filtering accumulates the sludge retention to be formed on ultra dense film flase floor, impurity
Fiber remove device can be automatically drained out impurity after being connected with transmission device, plus the ultra dense film of automatic back-washing cleaning device fixed time cleaning
It is automatically drained out on flase floor after unnecessary dirt, without artificial periodic cleaning, so as to cost-effective；The ultra dense film lattice of filter
Screen uses the filtering sheet material of special construction, and inverted triangle arc is spaced, fluid by when contact of the solids with grizzly bar
Face is small, though have finely ground particles by, due to grizzly bar rear portion gap it is wider and easily by, with reference to itself use gravity from
Manifold formula so that ultra dense film grid is not easy to form blocking, facilitates day-to-day operation maintenance management work, and grid surface is smooth, tool
There is the characteristics of smooth, can pass through fluid and the smooth smoothness of catalyst；Filter overall dimension width 1.1m~
1.6m, highly between 1.4m~1.7m, equipment small volume and less weight, irrigation canals and ditches need not be opened up during installation, only need to be by water inlet and preceding road
