Description

A kind of buck slagging-off oil removal device

Technical field

The present invention relates to a kind of buck slagging-off oil removal device.

Background technology

Boats and ships kitchen buck is meant the sewage that contains the vegetable and animals oils series products that produces from the cabin such as between boats and ships kitchen, dining room, dishwashing detergent; In the past because domestic and international environmental regulation does not propose processing requirements for boats and ships kitchen buck; Generally directly discharge; Along with the reinforcement of global ocean environmental consciousness, this problem more and more causes people's attention.The complicated component of boats and ships kitchen buck, organic content is high, mainly contains animal-plant oil, foodstuff fibre, starch, fat, all kinds of seasoning matter, washing composition and protein and vegeto-animal suspension residue etc.Pollutent in the buck of kitchen mainly exists with colloidal form; It is high to have SS, BOD, COD value height, grease and salt content, and the water quality and quantity variation waits characteristics greatly, and its drain time has certain rules property; Discharging moment flow is big, and Chinese meal and date for dinner generally are the peak periods of discharging.The kitchen buck can have a strong impact on harbour environment as not treated and be discharged into the harbour.The harm of boats and ships kitchen buck is mainly the drainability that influences pipeline, and the grease in the buck of kitchen forms oil layer at inner-walls of duct easily, the pipeline discharge capacity is reduced, even block.The pipe-dredging that grease stops up is difficulty very.If adopt membrane bioreactor that the kitchen buck is handled, oil content can be made film forming pollution.Can form oil film at the water surface after the buck discharging entry of boats and ships kitchen, influence the oxygen exchange of air and water body, reduce reoxygenation speed.Be scattered in the dissolved oxygen in the elaioleucite meeting consume water in the water, make water quality deterioration.The many poisonous and carcinogenic substance that contains in the oils, these materials by the hydrobiont picked-up, cause the hydrobiont distortion in water body, if get into human body through the long-pending effect of the richness of food chain, can be detrimental to health.

Summary of the invention

In order to address the above problem, the invention provides a kind of simple in structure, buck that tooling cost is low, easy to operate slagging-off oil removal device, can filter the suspension residue of removing in the buck of kitchen up hill and dale, and isolate wherein various oils compositions efficiently.

The present invention has adopted following technical scheme: a kind of buck slagging-off oil removal device, and it comprises housing, on housing, is provided with water-in and water outlet, in housing, is provided with collecting chamber, compartment, collection chamber and clear water chamber successively; Said water-in communicates with collecting chamber, is provided with the residue scoop in water inlet place of water-in, and said collecting chamber is connected with compartment, and buck gets into after the residue scoop arrives collecting chamber from water-in and arrives compartment then; The top of said compartment communicates with collection chamber, and the bottom is communicated with the clear water chamber, and said water outlet is connected with the clear water chamber.

The outside of said collecting chamber is provided with and the corresponding residue conveying end of residue scoop; Said water outlet is positioned at the position, middle and upper part in clear water chamber, and the center of water outlet is lower than the center of water-in; The top in said clear water chamber is provided with cover plate, is provided with relief outlet in the bottom in clear water chamber; The top of said compartment is provided with ventilation mouth; Said collection chamber is provided with oil discharge outlet; The bottom of said housing is provided with base.

The present invention has following beneficial effect: the present invention has simple in structure, compact, and oil-water separation is good, and the draining oil length is low, and the residue clearance rate is high, is difficult for stopping up and clearing up distinguishing features such as convenient; In the use, the kitchen buck enters into the collecting chamber residue scoop of flowing through from water-in, and the buck that is trapped behind the residue flows into compartment; Various oily substances in the buck float to the top of compartment at this moment; The buck that does not contain the oils material flows to the clear water chamber from the compartment bottom, and oily substance is isolated, and clear water intraluminal fluid face does not have oily substance; The final buck that does not contain the oils material is discharged by water outlet, gets into the waste disposal plant of buck subsequent disposal; In the compartment, along with the rising of liquid level, float on very long the overflowing in the collection chamber of oily substance on the liquid level, oil discharge outlet is positioned at the collection chamber middle part, discharges automatically when oil level reaches oil discharge outlet to focus on through the sump oil collection device; After this device work for some time; Assemble a lot of macrobead residues in the residue scoop; Bottom of device can precipitate a lot of small-particle residues simultaneously, can the residue scoop be taken out flushing, cleaning regularly from the residue conveying end; Avoided the inside of device to stop up, opened bottom drain valve in addition the small-particle residue of bottom settlings is discharged.
