The utility model content

The purpose of this utility model is to provide the high and low cost of a kind of oil removal efficiency and the water-and-oil separator smoothly of working.

The utility model is achieved in that a kind of water-and-oil separator, comprise water-in, decompression storehouse, separation bin and filtering cabin, the decompression storehouse is provided with venting port, separation bin is provided with oil discharge outlet, filtration medium is arranged in the filter core of filtering cabin, and described water-and-oil separator is provided with three separation bins and two filtering cabins, also is provided with a water level storehouse, the decompression storehouse communicates with first separation bin, is followed successively by second separation bin, the 3rd separation bin, water level storehouse, first filtering cabin and second filtering cabin afterwards;

Three separation bin tops are provided with pipeline and lead to same oil discharge outlet;

First separation bin and the second separation bin bottom are provided with pipeline and all lead to first sewage draining exit, and the 3rd separation bin bottom is provided with pipeline and leads to second sewage draining exit;

Two filtering cabin bottoms are provided with pipeline and lead to a water outlet.

The profit mixing portion is provided with poly-oily ball in described second separation bin and the 3rd separation bin.

Be provided with three filter cores in the described filtering cabin; Described filtration medium is oil strain ball and oil strain cotton.

All pipelines all adopt the PVC material in the described water-and-oil separator.

The utility model water-and-oil separator has two filtering cabins, can guarantee the works better of filtering system when a filtering cabin stops up, is not influencing the filtering cabin that normal water processing maintenance is simultaneously stopped up; Adopt three synergetic depth filtration systems of filter core in the filtering cabin, guaranteed filtering precision up to 99.9%, former equipment can only remain on about 80%, has improved filter effect greatly; The three-stage filtration that other three filter cores constitute has the obstruction relief function, guarantees that separator can not stop up, and when first step filter core stopped up, water directly entered second stage filter core by overflow weir; Filtration medium uses good oil strain ball of surface adsorption effect and oil strain cotton as material, and comparing former activated carbon filtration efficient has had very big improvement.

The utility model water-and-oil separator internal pipeline has adopted the pvc pipe material of high corrosion resistance, has guaranteed that inwall and surface can not be corroded under the prerequisite that works long hours, and iron pipe material has than before been saved manufacturing cost greatly, and has guaranteed quality.Be provided with poly-oily ball in second separation bin of the utility model water-and-oil separator and the 3rd separation bin, poly-oily ball can be adsorbed on the poly-oily ball and forms larger oil droplet being dispersed in extremely small oil droplet in the water, utilize the different larger oil droplets that make of oil to float on water surface formation oil reservoir, discharge by oil discharge outlet when reaching a certain amount of with the proportion of water.The effect in water level storehouse is a water level of guaranteeing each separation bin, has guaranteed that separation bin can keep normal operation.

The utlity model has following beneficial effect: the utility model water-and-oil separator oil removal efficiency height, cost is low and it is smooth and easy to work, and is difficult for stopping up.
