Abstract
The utility model relates to an oil isolation filter with granular filtering materials used for treating oily waste water without emulsion in factories, comprising an ejector, a filter, a filtering water inlet pipe, a filtering drainage pipe and other parts, wherein, polystyrene granular filtering materials are arranged in the filter. Oily waste water enters from the upper part of the filter, oil and water are separated by the filtering materials, and waste water is processed. The filtering materials need to be cleaned since the dirty oil on the filtering materials are excessive for some time. Clean water enters into the ejector through the water inlet pipe of the ejector in cleaning process, simultaneously the filtering materials are sucked to the ejector, and the filtering materials are cleaned under the scour of strong water stream. The filter materials and water after washing are conveyed to the filter through a filtering material conveying pipe, water is drained through a drainage pipe after flushing, the filtering materials rise to the bottom of the filter, and thus the filtering materials are entirely flushed via the circulation.
Description
The utility model belongs to a kind of sewage treatment equipment, is used for the oily(waste)water that processing plant does not contain emulsion, makes it can reuse or discharging.
Existing oil removal strainer has three kinds of structures, i.e. counterflush mode, surface washing mode, layering backwashing manner owing to clean the backwashing manner difference of filtrate.Shortcomings such as the greasy dirt developing result that these three kinds of modes exist on the filter material surface is bad, and the wash-down water consumption is big.In fact, washing water quantity can not excessively strengthen, so the treatment effect of the backwash rate of above-mentioned three kinds of strainers, oily(waste)water also can not improve a lot.
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of novel filtrate backwashing manner is provided, and makes the better oil removal strainer of oily(waste)water treatment effect.
The utility model is realized by following measure.
Foam polystyrene particle shape filtrate is placed in the strainer, and oily(waste)water enters from the top of strainer, and with oil, water sepn, greasy dirt is adsorbed in the waste water thereby make by filtrate, and waste water after treatment can reuse or discharging.
Behind the oily(waste)water process filter treatment certain hour, filtrate is surrounded by greasy dirt, has influenced treatment effect, at this moment will stop to handle waste water, handles filtrate.
For the filtrate cleaning performance is improved, in the oil removal filter top injector is housed, the inlet and the strainer of injector communicate, and the injector outlet is linked to each other with filter bottom by an extension tube attached.When the flushing filtrate, injector water inlet beginning, simultaneously filtrate is drawn in the injector, under powerful current scour, obtain cleaning at filtrate in the injector, filtrate after the cleaning and water are through pipeline inflow filter bottom, water water shoot after washing emits, and the filtrate of cleaning rises to the bottom of filtrate, and the filtrate that goes round and begins again is so all washed.
Accompanying drawing is the utility model structure iron.
As shown in the figure: (1) injector, (2) injector water inlet pipe, (3) filtered water inlet pipe, (4) strainer, (5) filtrate (styrofoam), (6) material level visor, (7) filtrate transfer lime, (8) vapor pipe, (9) water filtering and draining pipe, (10) draining perforated pipe, (11) flushing back water shoot
Below in conjunction with description of drawings the utility model performance.
As shown in the figure: oily(waste)water water inlet pipe (3) after filtration enters strainer (4), passes filtrate (5), and greasy dirt is adsorbed, isolates, and the water after the filtration is by water filtering and draining pipe (9) flow away (reuse or discharging).
Filter for some time, greasy dirt is too much on the filtrate, need wash filtrate.During flushing, with the valve open of injector water inlet pipe (2), injector begins water inlet, simultaneously filtrate (5) is drawn in the injector (1), and in injector (1) lining, filtrate (5) is obtaining cleaning under the current scour formidably.Filtrate after the cleaning and water are got back in the strainer (4) along filtrate transfer lime (7), and water is drained by flushing back water shoot (11), and the filtrate after the cleaning (5) rises to the bottom of strainer (4), and the filtrate that goes round and begins again is so all cleaned.
The utlity model has following advantage:
1. adopt a foamed polystyrene material filtrate, oleophylic, hydrophobicity are good.
2. the employing injector makes it filtrate and is obtaining cleaning under the current scour formidably, and the filtrate cleannes improve greatly.
Claims (2)
1, a kind of granule filter material oil removal strainer, form by parts such as injector, strainer, filtered water inlet pipe, water filtering and draining pipes, put the granules of polystyrene filtrate in the strainer, it is characterized in that being equipped with on the strainer (4) injector (1), injector (1) inlet communicates with strainer (4) top, and outlet communicates with strainer (4) bottom through filtrate transfer lime (7).
2, according to the described granule filter material oil removal of claim 1 strainer, it is characterized in that cleaning water enters in the injector (1) through injector water inlet pipe (2), simultaneously filtrate (5) is drawn in the injector (1), filtrate (5) obtains cleaning under big current scour, filtrate after the cleaning (5) and water are got back in the strainer (4) through filtrate transfer lime (7), water water shoot (11) after washing is drained, and filtrate rises to the bottom of strainer (4).
