As an improvement of the present invention, the tilt angle of the filter plate two and filter plate three is 30-40 °.
As an improvement of the present invention, the tilt angle of the filter plate two and filter plate three is 33 °.
As an improvement of the present invention, the mesh of the filter plate two and filter plate three is 0.3-0.6mm.
As an improvement of the present invention, the mesh of the filter plate one is 0.1-0.3mm.
As an improvement of the present invention, the filter opening aperture of the polypropylene filter is 30-50 μm.
As an improvement of the present invention, suck-back device is equipped between the pipeline and water pump.
As an improvement of the present invention, active carbon particle is equipped in the adsorption layer.
As an improvement of the present invention, the filter plate two and three back side of filter plate are equipped with support frame.
The beneficial effects of the present invention are:
A kind of dyeing waste water filter device of the present invention, structure is simple, utilizes multiple filtration plate filtered wastewater, cotton
Yarn, fiber, impurity are intercepted at outside polypropylene filter, and filter efficiency is high, and the COD value in waste water is low, device beauty, anti-corrosion, close
Envelope, high degree of automation, environment is good, at low cost, and blowdown is convenient, long service life.

Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As shown, a kind of dyeing waste water filter device of the present invention, including Rose Box 1, set in the Rose Box 1
There is vertical stainless steel filter plate 1, one 2 right side of filter plate is pasted together with polypropylene filter 3, and filter plate 1 will filter
Case is divided into coarse filter area 4 and fine filter area 5, is equipped with slanting filter plate 26 and filter plate 37, the filter plate in the coarse filter area 4
26 and filter plate 37 inclined surface in face of the left side of Rose Box 1, filter plate 26 is on the left of coarse filter area, and filter plate 37 is in coarse filter area
4 right sides, the height of filter plate 26 are lower than the height of filter plate 37, and the filter plate 37 is equipped with inductor 8, the induction
8 height of device is identical as the height of filter plate 26, and 1 upper left side of Rose Box is equipped with water inlet 9, and the water inlet 9 is arranged in mistake
The left side of filter plate 26, the fine filter area 5 are equipped with adsorption layer 10, are equipped with water outlet 11, the water outlet below the adsorption layer 10
11 are connected to header tank 13 by pipeline 12, and 12 side of pipeline connects water pump 14.
A kind of dyeing waste water filter device of the present invention, when work, dyeing waste water enters Rose Box 1 from water inlet 9
It is interior, the left side of filter plate 26 is first fallen in, waste water passes through filter plate 26, filter plate 37, filter plate 1, polypropylene filter 3, suction
Attached layer enters header tank 13, and using multiple filtration plate filtered wastewater, cotton yarn, fiber, impurity are intercepted at outside polypropylene filter, mistake
Filter efficiency reaches 99.8%, and the COD value in waste water is low, and the inclined surface of filter plate 26 and filter plate 37 of the present invention faced
The left side of filter box 1, it is contrary with the filter plate of general filter plant, it is oppositely arranged can be whole by sundries, the fiber in waste water
For gear in 26 left side of filter plate, filter efficiency is high, does not have sundries leakage;When wastewater flow rate is big, waste water height is more than filter plate 26
When the 2/3 of Rose Box 1 (2 6 height of filter plate be), inductor 8 senses that waste water height is more than normal value, control system starting
Water pump 14 makes to form negative pressure in pipeline 12, accelerates waste water trickling speed, improves working efficiency, the configuration of the present invention is simple, filtering effect
