It is separated.Lacquer spraying technique waste water is handled using the present apparatus, adjustment cooling temperature, the revolving speed for stopping roller can receive preferably
Treatment effect makes that treated waste water is substantially all to filter out paint slag and most organic solvents, thus have preferably circulation make
Use performance.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the structural schematic diagram for painting slag settler.
Specific embodiment
With reference to the accompanying drawing, the present invention will be further described:
As depicted in figs. 1 and 2, this purification device includes paint slag settler 1, and paint slag settler 1 includes shell 2, and housing bottom is set
It is set to inverted taper, other each faces can be set to rectangle.There are water inlet 3 on the left plate of shell, set on right side plate
It is equipped with water outlet 4, waste residue outlet 5 is provided in the taper of bottom, valve is housed in waste residue outlet 5.Waste water is flowed through water inlet 3
It to water outlet 4, paints slag and is separated by waste residue outlet 5, wherein inverted conical by its shape is conducive to that slag will be painted and preferably separates
Out.Multiple upper barrier plates 6, the top plate and front and back side plate stationary phase of upper barrier plate and shell are provided on the inside of the top plate of shell
Even, there are one and between the bottom plate of shell to fix gap 61 for allowing water to flow through;Multiple lower barrier plates 7 are provided on bottom plate,
Lower barrier plate 7 is staggered with upper barrier plate 6, the bottom plate and front and back side plate of lower barrier plate and shell be fixedly linked and with shell
There are certain upper gaps 71 between top plate.When inside of the waste water by paint slag settler 1, upper and lower barrier plate is staggeredly equipped with
Effect increases retention time of sewage, to paint slag with the sedimentation time.It further, can also be upper and lower in order to enhance effect of settling
Barrier plate outer cover consolidates rubber filter mantle, and the abscess 9 of protrusion is distributed in the surface of rubber filter mantle, divides between abscess and abscess
It is furnished with rubber villus 10, abscess is conducive to paint slag and collects, prevents from flowing away with water, the villus between abscess facilitates organic in waste water
The convergence of drop creates conditions in advance for the separation removal of subsequent organic matter.Two relative rotation can also be set in water outlet
Blocking roller 11, stop to coat villous 12 on roller, stop to be equipped on the inside of roller villus can be scraped smooth out with the fingers mouthful frame 13, resistance
Block roller 11 drives 12 relative rotation of villus thereon, can play barrier effect again to the slag of paint slightly also remaining in waste water,
And these paint slags are clamped in villus by villus, it then beats on smoothing out with the fingers mouthful frame 13, to complete more thorough to paint slag
Filter out.Preferably, the revolving speed of roller at work is stopped to may be configured as 30 ~ 60 turns per minute, this revolving speed is conducive in water flow
Balance is obtained between sedimentation.The front side board of shell is removably sealingly mounted on shell, and it is heavy to paint slag to can be convenient in this way
The inside of drop device carries out cleaning or maintenance protection.Painting wastewater obtains purifying waste water for the first time after painting slag settler.
The water inlet of water pump 14 is connected with the water outlet of paint slag settler 1, the water outlet of water pump 14 and cooler 15 into
The mouth of a river is connected, and first time purification waste water is actively delivered to cooler 15 by water pump 14, and in cooler that first time purification is useless
Being water-cooled to water temperature is 5 ~ 15 DEG C then from the output of the water outlet of cooler.
The water inlet of coarse device 16 is connected with the water outlet of cooler 15.Coarse device 16 includes warehouse 17, water inlet
The lower part of warehouse is set, and the warehouse other side is located at the water outlet that upper position is provided with coarse device, pacifies on the top of warehouse
Equipped with the first oil catcher 18.Many layer support frames 171 are internally provided in warehouse, are stacked with coarse material granule on support frame
(not shown), it is preferred that coarse particle can for selected from PP GRANULES, granules of polystyrene, smokeless coal particle or
The diameter of the one or more of ceramic particle, coarse material granule can be set as 3 ~ 5mm, of this partial size scale accumulation
Grain is easier that organic liquid is made to form larger particles.When purification waste water flows through coarse device 16 for the first time, from filling out for coarse device
Gap between material is flowed through, and purifies waste water for the first time when being in contact with filler, for the first time organic drop in purification waste water
It further grows up and swims in top, and then collected by the first oil catcher 18, remaining waste water is arranged through the water outlet of coarse device
Out, second of purification waste water is obtained.
Second of purification waste water flows into the water inlet of inclined separator 19 through the water outlet of coarse device 16.Inclined separation
Device includes the first cavity 191 and the second cavity 192, and two cavitys are linked together in bottom by communication port 20.Water inlet setting
On the top of the first cavity 191, the first cavity side plate inside and be located at below water inlet and be provided with the plate 21 that meets water, meet
Water plate 21 tilts upward setting, plays the role of the impact that raises up to water flow, is conducive to subsequent particle growth, second of purification waste water
After water inlet inflow, flowed out by the upper end for the plate that meets water.It meets water and multiple inclined tubes 22 arranged side by side is installed below plate, tiltedly
Pipe 22 is arranged diagonally downward and inclined tube lower end is connected with the communication port 20 of two cavity bottoms, the water flowed down from the plate 21 that meets water
Communication port is flowed by inclined tube 22 and then is entered in the second cavity 192.Above-mentioned inclined tube may be set to be inclined plate or other can
To realize the structure of function.The setting of inclined tube or inclined plate is conducive to organic matter and is settled by gravity.It is erected in the second cavity
Water fender 23 directly is installed, the bottom plate and front and back side plate of water fender and the second cavity link together, and inclined separator
Water outlet is mounted on the right side plate lower position of the second cavity.Second oil catcher 24 is installed at the top of inclined separator, second
Oil catcher is respectively communicated with the first cavity and the second cavity, when second of purification waste water flows through inclined separator 19, swims in top
The organic liquid in portion is collected by the second oil catcher, remaining waste water is discharged through the water outlet of inclined separator, can be completed to spray painting
The purification process of waste water.
By apparatus above and corresponding technique, painting wastewater is purified well, and obtained purified water follows
Ring still keeps certain dissolving power to organic matter using repeatedly, has the advantages that paint removal slag effect is good, water-saving and environmental protection.
The present embodiment is to be not intended to limit it, present inventive concept and the explanation realized in structure of the present invention
Under think of, without the technical solution that substantially converts still in protection scope.
