Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Fig. 1～7, the casing 1 of this catering oil-water separator is divided into four chambers, be respectively intake antrum 102, the first treating chamber 103, the second treating chamber 104, water chamber 105, intake antrum one side is provided with water-in 101, in intake antrum, be provided with the slagging-off screen frame 2 that removable jew connects, water chamber one side is provided with water outlet 106.In the first treating chamber, the second treating chamber, renovate 401 and renovate with the dividing plate 4 of handle and be separated to form negative area 10301 and filtrating area 10302 by an end face is hinged separately, dividing plate is vertical with the wallboard of separating the first treating chamber, the second treating chamber in casing, and bottom, negative area communicates by the passage forming between dividing plate and tank floor with bottom, filtrating area.Wall in the filtrating area separately of the first treating chamber, the second treating chamber is provided with the boss 9 for supporting filter, and strainer offsets spacing with boss from filtrating area upper end open is put into.The structure of strainer can adopt the scheme of prior art, and strainer is made up of framework 5 and the filter packing 6 that hangs in framework as shown in Figure 3.Also can adopt the designed filtration device structure as shown in Figure 4, Figure 5 of the utility model, it comprises rectangular parallelepiped framework, the filter packing of upper end open, framework bottom is provided with equally distributed micro-filtration hole 501, in framework, be provided with the filter plate 7 along framework bottom to top undulate, the plate face of filter plate is provided with guiding water from framework bottom to the limbers 701 that top undulate flows to.Each crest, trough place and the framework inwall of filter plate offset, between filter plate after offseting and framework inwall, form multiple triangular spaces, in triangular space, place the spherical filter packing with adsorption filtration and bio-film colonization effect, form the strainer after the utility model improves.For convenience of this cleaning filter, be provided with the handle 8 that filter plate is taken out from framework top at the top of filter plate, separate with framework thereby realize filter plate, facilitate replacing or the cleaning operation of filter packing.
The concrete through-flow structure of above-mentioned intake antrum, the first treating chamber, the second treating chamber, water chamber is: intake antrum top is provided with the outlet pass communicating with the first top, treating chamber negative area, wherein in intake antrum, connect this outlet pass by tee pipe fitting 3, between the top, filtrating area of the first treating chamber and the top, negative area of the second treating chamber, communicate by outlet pass, between the top, filtrating area of the second treating chamber and water chamber top, communicate by outlet pass, in water chamber, connect water outlet by tee pipe fitting.In said structure, the water-in height design of casing is the outlet pass height communicating higher than intake antrum, the first treating chamber, the second treating chamber, water chamber, water outlet height is designed to the outlet pass height communicating lower than intake antrum, the first treating chamber, the second treating chamber, water chamber, and the outlet pass height that intake antrum, the first treating chamber, the second treating chamber, water chamber communicate is identical.
For convenient filter is positioned in filtrating area, be detachable with the first treating chamber, the second treating chamber by baffle design, specifically, by the guide and limit seat at the first treating chamber, the default grafting dividing plate of the second treating chamber inwall, dividing plate is inserted in guide and limit seat can be fixed.So, in the time that strainer is installed, first strainer is put on the boss of filtrating area, and then dividing plate is inserted, comparatively simple.
In order to prevent that the passage between dividing plate bottom and tank floor from stopping up, the bottom surface of the first treating chamber, the second treating chamber is set to slope down to negative area by filtrating area, can effectively prevent that the problem of stopping up from occurring.
Specific works principle of the present utility model is: the intake antrum that enters catering oil-water separator with the oily(waste)water of residue from the water-in of casing, macrobead residue drops in slagging-off screen frame, removing oily(waste)water after macrobead residue varies in size because of proportion, oil slick slowly rises and condenses upon the top of intake antrum, the sewage of removing a large amount of oil slick enters from the bottom opening of tee pipe fitting, flows into the first treating chamber.First the oily(waste)water that enters the first treating chamber enters negative area, part oil slick again rises and condenses upon top, negative area, the sewage of remove portion oil slick is entered in filtrating area by bottom, negative area, sewage upwards flows from the bottom of strainer, in this process, sewage fully contacts with the filter packing of filter interior, a large amount of microorganisms in sewage are attracted on filter packing, form filtering membrane, filter packing has Filtration Adsorption and bio-film colonization effect, and the various pollutent indexs in sewage are significantly reduced.The process filter sewage after treatment after filtration outlet pass at top, district enters in the second treating chamber, and negative area, filtrating area in the second treating chamber are identical with the mode of action in the first treating chamber, and the sewage through secondary settlement and after filtering enters water chamber.In water chamber, residue grease and suspended substance floating, heavy residue is deposited in water chamber bottom, and the tee pipe fitting bottom opening place of sewage after treatment in water chamber flows into, and is disposed to municipal blowdown pipe network through water chamber water outlet.
Said structure and principle of work are intended to illustrate technique means of the present utility model, and unrestricted technical scope of the present utility model.Those skilled in the art do apparent improvement in conjunction with existing common practise to the application, for example: increase and the first treating chamber, several treating chambers that the second treating chamber function is identical, handle convenient filter is set on strainer from apparent improvement such as filtrating area taking-ups, within all falling into the utility model claim scope.
