Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The oil-water separation device for the kitchen comprises a box body 1 and a box cover 2 which is arranged on the box body 1 and is used for sealing an opening at the top end of the box body 1, wherein a sealing gasket is arranged at the bottom of the box cover 2; the side wall of the box body 1 is provided with a water inlet 3 for inputting kitchen waste water-oil mixture into the box body 1, and the water inlet 3 is preferably arranged at a position close to the bottom surface.
The inner side of the water inlet 3 is provided with an isolation net 4 for directly keeping dregs in the water-oil mixture in the separation tank, the filter net 4 is of a right-angle structure, the front side and the rear side of the isolation net 4 are respectively connected with the front side plate and the rear side plate of the box body, the left side edge of the isolation net 4 is connected with the box body side plate in the middle of the water inlet, and the lower side of the isolation net 4 is connected with the box body bottom plate; the isolation net separates two spaces in the box body, one is a residue space connected with the water inlet, and the other is an oil-water space. The slag separation plate is made of a super-hydrophobic copper net with good performance, and the super-hydrophobic copper net can still keep about 80% of separation efficiency after being inspected by an oil-water mixture of four organic matters such as normal hexane, dimethylbenzene, kerosene and methylene dichloride which are common in industrial oily wastewater, so that better separation of oil slag is facilitated.
An oil-water separation device 5 is arranged in an oil-water space of the box body 1, the oil-water separation device 5 is used for separating oil from water, the oil-water separation device 5 comprises a water absorption branch pipe 52 and a water discharge pipe 53, the upper end of the water absorption branch pipe 52 which is bent at 90 degrees is connected to the middle part of the water discharge pipe 53 which is vertically arranged, the water absorption branch pipe 52 and the water discharge pipe 53 form an h-shaped structure, a lower port of the water absorption branch pipe 52 is connected with a pipe-shaped filter screen 51, the edge of the lower end of the filter screen 51 is contacted with the bottom surface of the box body, and the height of the filter screen 51 is 0.5-3 cm; the filtering holes of the filtering net 51 are smaller than those of the isolation net 4, and the filtering net 51 can filter small residues when the water absorption branch pipe 52 absorbs water; the lower end of the drain pipe 53 is bent at 90 degrees and is connected with a water outlet hole on the wall of the tank, the upper end of the drain pipe 53 is provided with an exhaust port 54, and the exhaust port 54 is higher than the liquid level in the tank when in use. When the liquid level in the tank body is lower than the connection position of the water suction branch pipe 52 and the water discharge pipe 53, the water in the water suction branch pipe 52 cannot enter the water discharge pipe 53, and then cannot be discharged; when the liquid level in the tank is higher than the height of the connection position of the water suction branch pipe 52 and the water discharge pipe 53, the water entering from the water suction port is discharged from the water discharge port through the water suction branch pipe 52 and the water discharge pipe 53. Therefore, when the liquid level is low, oil and water are mixed in the lower liquid, and at the moment, the water cannot flow out; when the liquid level is high, water flows out from the lower part of the water tank when the water is in oil, so that oil-water separation is ensured, and the water containing oil can not be discharged. When more oil is visually detected in the box body, the oil is scooped out, so that the recovery of waste oil is facilitated. The device can separate oil, slag and water independently, does not need to consume chemical reagents, does not cause secondary pollution, and has low operation and maintenance cost. When in use, the liquid in the box body is periodically emptied, the isolation net 4 is opened to clean residues, and the box body is cleared, so that the residues on the inner wall of the box body are prevented from deteriorating.

2. By utilizing the density difference and the immiscibility of the oil phase and the water phase, the oil-water mixture is enabled to realize the separation of the oil phase and the water phase under the action of gravity under the static or slow flowing state. The kitchen waste water-oil mixture can directly enter isolation residues passing through the isolation net 4 from the water inlet 3, filtered wastewater enters the sweet water pipe 53 through the filter screen 51 and the water absorption branch pipe 52, and is directly discharged from the water outlet of the water discharge pipe 53, and the air inlet hole in the water discharge pipe 53 is arranged at the top; because oil floats on the water surface, the stainless steel box cover 2 can be opened to directly hold the oil from the upper part, the recovery of waste oil is facilitated, the oil, the slag and the water can be separated independently, the consumption of chemical reagents is not needed, secondary pollution is avoided, and the operation and maintenance cost is low.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
