At present, the general volume of the filter plant that uses in the wastewater treatment process is larger, and complex structure is difficult for dismounting and change after the installation, need to use scour without sediment motion when filter net jam, causes the wasting of resources.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of sewage filter device is provided, this filter apparatus configuration is reasonable, easy to use, when needs clean, as long as removable filter medium (being filter screen) is taken out, reload after the cleaning and can use, working service is very convenient.
The technical scheme that provides according to the utility model, described sewage filter device, comprise framework and the filter screen that is arranged on the framework sidepiece, feature is: described framework comprises outer frame body and one deck internal frame body at least, and outer filter and the inner filter screen that can insert and extract out all is installed at the sidepiece of described outer frame body and each side of internal frame body.
The aperture of described outer filter is less than the aperture of inner filter screen.
The height of described outer filter is equal to or greater than the height of inner filter screen; Top at described internal frame body is provided with overflow means, and the outlet of overflow means is connected into outside cesspool.Described overflow means is overflow pipe or overflow launder.
The bottom of described outer frame body and internal frame body is provided with base plate, and the upper end is opening.
Framework at described outer frame body and internal frame body is provided with the draw-in groove that cooperates with outer filter and inner filter screen respectively, and/or is used for the buckle of fixed outer layer filter screen and inner filter screen.
Described outer filter and inner filter screen are the one-piece construction with outer frame body or internal frame body sidepiece form fit, perhaps are the full slice system structure with outer frame body or internal frame body form fit.
Between described outer frame body and internal frame body, perhaps also be provided with one or more sets frameworks in the inside of internal frame body, filter screen all is set on the framework, the aperture of filter screen from inside to outside reduces successively.
Sewage filter device described in the utility model is simple in structure, and is easy for installation; Filter screen adopts multiple-piece or full slice system structure, and convenient disassembly is easy to safeguard or change; The utility model has been installed overflow means, can control the sewage quantity in the filter screen, also prevents sewage outflow simultaneously, guarantees filter effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposing state figure of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
Such as Fig. 1 ~ shown in Figure 2: sewage filter device comprises outer frame body 1, outer filter 2, internal frame body 3, inner filter screen 4, overflow means 5 etc.
The utility model comprises framework and is arranged on the filter screen of framework sidepiece, described framework comprises outer frame body 1 and one deck internal frame body 3 at least, and the bottom of described outer frame body 1 and internal frame body 3 is provided with base plate, and the upper end is opening, be convenient to connect water feed apparatus, the water in the cesspool is transferred in the internal frame body 3; Outer filter 2 and the inner filter screen 4 that can insert and extract out all is installed at the sidepiece of described outer frame body 1 and internal frame body 3 each side;
The aperture of described outer filter 2 is less than the aperture of inner filter screen 4, and sewage is the 2 mobile multistage filterings that carry out from inner filter screen 4 to outer filter;
The height of described outer filter 2 is equal to or greater than the height of inner filter screen 4, prevent that on the one hand the sewage after inner filter screen 4 filters from directly flowing out outer frame body 1 outside without outer filter 2 filters, prevent that on the other hand the water-holding quantity between inner filter screen 4 and the outer filter 2 is too much, reduce filter efficiency;
