Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of domestic sewage treatment devices, and in particular to an oil-water separation device for rural domestic sewage. Background Technology
[0002] In daily life, every household generates domestic sewage, which contains a large amount of organic matter and pathogenic microorganisms. With the improvement of living standards, the discharge of rural domestic sewage is increasing year by year. While the concentration of major pollutants in rural domestic sewage is lower than that in urban sewage, it contains more impurities. Organic matter in domestic sewage easily decomposes, producing foul odors, while pathogenic microorganisms use this organic matter as nutrients to multiply rapidly, producing large amounts of harmful substances. Therefore, domestic sewage needs to be purified before being discharged.
[0003] A search revealed a rural domestic sewage treatment device under publication number CN219194736U, comprising a filtration tank, an oil-water separation tank, and an adsorption tank connected sequentially to one side of the filtration tank. A water inlet is located at the bottom of the side of the filtration tank adjacent to the oil-water separation tank, and another at the bottom of the side of the oil-water separation tank adjacent to the adsorption tank. An inlet is located near the top of the filtration tank. A filtration device is installed inside the filtration tank, located below the inlet. An oil-water separation device is installed inside the oil-water separation tank, and an adsorption device is installed inside the adsorption tank. An outlet is located near the bottom of the adsorption tank. This invention filters impurities from sewage through a series of operations involving the filtration device, oil-water separation device, and adsorption device. Then, the grease in the sewage is collected and centrally treated. Finally, harmful substances in the sewage are adsorbed, and the treated sewage can be reused.
[0004] Although the above-mentioned method adsorbs harmful substances in sewage and the treated sewage can be reused, it does not filter out solid impurities in sewage, the separation effect of oil is not good enough, and the efficiency of subsequent adsorption of impurities in sewage is low, resulting in poor purification effect. Utility Model Content
[0005] The main purpose of this utility model is to provide a rural domestic sewage oil-water separation device. The separation unit solves the problems of not filtering out solid impurities in sewage and insufficient separation effect of oil. The processing unit solves the problems of low efficiency and poor purification effect in subsequent adsorption of impurities in sewage.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rural domestic sewage oil-water separation device includes a main body, a separation unit disposed at the top of the main body, and a treatment unit disposed at the bottom of the separation unit.
[0008] The separation unit includes a temporary storage frame disposed inside the main body, two openings at the top, a filter assembly disposed inside the openings, and an oil absorption assembly disposed inside the temporary storage frame.
[0009] The processing unit includes a purification component disposed at the bottom of the temporary storage frame, and a discharge component disposed at the bottom of the purification component.
[0010] Preferably, the impurity filtering component in the separation unit includes a pull-out frame disposed inside the opening and a filter screen disposed at the bottom of the pull-out frame.
[0011] Preferably, the oil-absorbing component in the separation unit includes a telescopic device fixedly connected to the middle of the top of the main body, a telescopic column fixedly connected to the bottom of the telescopic device, a snap-fit frame fixedly connected to the bottom of the telescopic column, and a convex snap-fit groove opened inside the snap-fit frame.
[0012] Preferably, the oil-absorbing component in the separation unit further includes a hydrophobic sponge disposed inside the snap-fit groove, and a valve fixedly connected to the bottom of the temporary storage frame.
[0013] Preferably, the hydrophobic sponge in the separation unit is filled with graphene and polydimethylsilane. The graphene and polydimethylsilane work together to allow the hydrophobic sponge to repeatedly absorb oil. When the hydrophobic sponge is squeezed, the graphene will not flow out with the oil, and the hydrophobic sponge will not absorb water.
[0014] Preferably, the purification components in the processing unit include a connecting plate disposed on the front of the main body, two fixing frames fixedly connected to the back of the connecting plate, extension rods fixedly connected to both sides of the fixing frames, a filling layer filled with activated carbon disposed inside the fixing frames, and multiple limiting blocks fixedly connected to both sides inside the main body.
[0015] Preferably, the discharge component in the processing unit includes an inclined plate disposed at the bottom end of the limiting block, a through hole opened on one side of the inclined plate, a plurality of partition plates fixedly connected to the bottom end of the inclined plate and the top end of the main body, a feed pipe that penetrates the outer shell of the main body and is located at the top of the through hole, and a discharge pipe connected to one side of the bottom end of the main body.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] I. In this utility model, by setting up a separation unit, domestic sewage is introduced through an opening. The sewage stays in the pull-out frame and then moves downward through the filter screen to the temporary storage frame. The filter screen blocks solid impurities in the sewage. Then, the telescopic device is activated to drive the snap-fit frame and the hydrophobic sponge to descend, so that the hydrophobic sponge comes into contact with the sewage. The hydrophobic sponge adsorbs the oil in the sewage. Then, the pull-out frame is raised to remove the solid impurities. The hydrophobic sponge can also be pulled out, the oil can be squeezed out, and then it can be put back into the snap-fit groove for repeated use. This optimizes the filtration efficiency of solid impurities and the separation effect of oil.
[0018] II. In this utility model, by setting up a treatment unit, the valve is opened to send out the separated sewage. The sewage first comes into contact with the activated carbon in the filling layer, and some impurities are adsorbed by the activated carbon. Then the sewage moves through the inclined plate and falls through the through hole. Multiple partition plates form a long moving channel, and the purifying agent is sent in through the feed pipe. The purifying agent and sewage react fully in the moving channel. The purified sewage is discharged through the discharge pipe, which improves the efficiency of sewage treatment and the purification effect. Attached Figure Description

[0038] Domestic sewage is introduced through the opening and stays in the pull-out frame 202. Then, the sewage moves downward through the filter screen 206 to the temporary storage frame 207. The filter screen 206 blocks solid impurities in the sewage. Then, the telescopic device 201 is activated to lower the snap-fit frame 205 and the hydrophobic sponge 204, so that the hydrophobic sponge 204 comes into contact with the sewage.
