8. The inner cavity of the oil-water separation device is divided into a plurality of cavity areas: A. a first oil-water separation zone: namely a large pipe section of the absorption water inlet pipe. The small pipe of the absorption water inlet pipe is connected with a drain pipe of kitchen waste water, and after the kitchen waste water flows into the large pipe through the small pipe at a certain flow rate, the upward flowing speed of the waste water in the large pipe is reduced and the waste water flows into the inner cavity of the shell at a smaller flow rate, so that the first-step oil-water separation is carried out in the cavity of the large pipe; B. a second oil-water separation zone: i.e., the area between the outer wall of the accelerating siphon bell and the inner wall of the housing. After the wastewater flows into the second oil-water separation zone through the absorption water inlet pipe, because of the light oil and the heavy water, the oil in the wastewater stored in the second oil-water separation zone floats upwards, and simultaneously the water and the residues sink downwards, finally the oil floats on the water surface, the upper layer is the oil, the lower layer is the water and the residues, and the secondary separation of the oil, the water and the residues is carried out; C. isolating and resisting the cavity: the clearance between siphon blow off water pipe outer wall and the acceleration siphon cover inner wall is promptly to separate and hinders the chamber, and its effect is that oil, water and residue after separating, when the siphon effect produced, water and residue through separating hinder the chamber and discharge through siphon blow off water pipe, hinder the chamber through separating simultaneously and prevent that the oil that separates is discharged by siphon blow off water pipe. The cross-sectional area of the blocking cavity is limited (namely the distance between the outer wall of the siphon sewage discharge pipe and the inner wall of the acceleration siphon cover), and the purpose of reducing the flow-through current-carrying area is to increase the flow velocity to provide the upward power for water and sundries entering the blocking cavity, so that the water and the sundries can be discharged conveniently; D. a vacuum adjusting area: the siphon degree regulating device is arranged at the upper part of the separation cavity, when the siphon degree regulating device is regulated, the vacuum degree (actually not complete vacuum, but negative pressure less than atmospheric pressure can be generated when siphon occurs) of a vacuum degree regulating area can be changed, when the regulating device is in a complete closing position, the upper part of the separation cavity is blocked with an atmospheric channel, when waste water is discharged through a siphon sewage discharge pipe, air in the upper cavity of the separation cavity is taken away under the action of water flow to enable the upper cavity of the separation cavity to generate vacuum suction force, so that water and residues precipitated in the second oil-water separation area and the lower part of the separation cavity are rapidly discharged into a sewer pipeline at an accelerated speed, the function of generating the vacuum suction force is to rapidly discharge sediment residues in the waste water cleanly and completely, and the operation premise is that oil stored at the upper part of the oil-water separation cavity is firstly manually discharged to be operated, when the siphon adjusting device is completely closed, the annular channel and the siphon sewage discharge pipe form a siphon pipeline which can suck water in the second oil-water oil separation area and the lower part of the separation and resistance cavity, the oil separation and resistance effect of the water is damaged, oil can be discharged into the sewage pipe, and the siphon adjusting device can only completely close the siphon degree when the siphon kitchen waste water oil-water separation device is cleaned. Under normal conditions in use, adjust siphon degree adjusting device according to waste water volume size, that is to say only a large amount of waste water gets into second oil-water separation district, just produces less negative pressure when siphon blow off water pipe is full of the pipe, discharges the impurity acceleration in the waste water fast.

9. In order to realize automatic oil drainage, the lower part of the siphon oil drainage pipe extends into an oil storage area of the second oil-water separation cavity area, and a lower opening is higher than the inlet of the siphon sewage drainage pipe. Because the inlet of the siphon oil discharge pipe is higher than the siphon sewage discharge pipe, water cannot be poured.

10. Drainage working principle of siphon sewage discharge pipe

When the small flow is drained: when the waste water after washing dishes passes through a rough filter screen of the washing basin, enters a waste water absorption and absorption pipe from the lower part through a pipeline to dissipate energy upwards and then overflows from an upper port, enters a second oil-water separation zone, oil floats upwards, the waste water and impurities sink into the second oil-water separation zone and are adjacent to a blocking chamber, the water level of the blocking chamber continuously rises along with the continuous increase of the separated waste water, when the water level is higher than the water inlet of a siphon sewage pipe, the waste water is discharged into the sewage pipe from the siphon sewage pipe, because a siphon degree adjusting device is initially adjusted at a common working position (can enter air in a small amount), a small air vent is arranged between a vacuum degree adjusting zone at the upper part of an acceleration cover and the atmosphere, the flow is small, no pipe water is filled in the siphon sewage pipe, the siphon sewage pipe is communicated with the vacuum degree adjusting zone, and the blocking chamber and the siphon sewage pipe form a siphon pipeline, the flow velocity of the blocking cavity can not be accelerated, so that the oil-water separation is facilitated. Because the impurity in the waste water is also few when the small flow, can not cause the piling up of impurity yet not accelerating, can not influence normal work.

During large-flow drainage: after having a large amount of waste water in the wash basin through the wash basin coarse strainer, get into the waste pipe and up the energy dissipation back of helping hand from the lower part through the pipeline, spill over from the upper port and get into second oil water separation zone after, oil is toward the come-up, waste water and impurity are down to sink and are got into second oil water separation zone and separate and hinder the adjacent department in chamber, along with the waste water continuous increase of separation, the water level that separates and hinder the chamber constantly rises, when the water level is higher than siphon blow off water pipe water inlet, waste water is followed siphon blow off water pipe and is discharged sewer pipe. Because the siphon degree adjusting device is adjusted at a common working position, only a small vent hole is formed between the vacuum degree adjusting area at the upper part of the acceleration siphon cover and the atmosphere, the water discharge amount is large, full pipe water in the siphon sewage discharge pipe is discharged downwards to separate the atmosphere in the sewage pipe from the vacuum degree adjusting area, air in the vacuum degree adjusting area is discharged into the siphon sewage discharge pipe in large amount and is taken away by water, and the taken air is far larger than the air input of the siphon degree adjusting device adjusting hole, so that the vacuum suction force is generated in the vacuum adjusting area. The siphon sewage pipe and the blocking cavity form a siphon pipeline condition, the vacuum suction in the vacuum adjusting area accelerates the flow velocity in the blocking cavity, increases kinetic energy for impurities in the wastewater at the bottom of the second oil-water separation area, quickly enters the blocking cavity, and is discharged into a sewer pipeline from the siphon sewage pipe, so that the accumulation of the impurities in the wastewater is avoided, the impurities are timely discharged, bacteria are less generated, the sanitation is facilitated, the inner cavity of the oil-water separation device cannot be blocked due to too many accumulated impurities, when the flow is gradually reduced, the air of the siphon sewage pipe is smaller than the air inflow of the adjusting hole of the siphon degree adjusting device, the siphon pipeline condition of the siphon sewage pipe and the blocking cavity is destroyed, the flow velocity in the blocking cavity is reduced, siphon is stopped, and the water in the blocking cavity and the oil-water separation cavity is maintained at the position of the siphon sewage pipe opening.

11. Operation for cleaning internal cavity of oil-water separating device

The manual oil drain valve is opened first, the oil in the oil storage area is put into the prepared bottle, and then the oil drain valve is closed. Rotating the siphon degree adjusting device to be completely closed, pouring warm water containing about 70 degrees of detergent into a kitchen basin from a kitchen basin, passing through a basin fine filter net, entering the force-eliminating water inlet pipe from the lower part through a pipeline, and stopping adding water when the temperature of water discharged by a siphon sewage discharge pipe is about 60 degrees. When about ten minutes, a large amount of warm water of about 70 degrees is poured into the wash basin at one time, at the moment, a large amount of siphon sewage discharge pipes are full of pipes for water discharge, because the adjusting holes of the siphon degree adjusting device are completely closed, a large amount of water discharge accelerates air above the siphon cover to be taken away in a large amount, so that strong vacuum suction is generated, the blocking cavity and the siphon sewage discharge pipes form a siphon pipeline, sewage and impurities under the action of the warm water and detergent are rapidly discharged into the sewage discharge pipe from the siphon sewage discharge pipes, and because the siphon degree adjusting device on the upper part of the vacuum adjusting area of the siphon cover is completely closed, the siphon work is finished after the sewage and the impurities in the oil-water separation cavity are completely sucked. Finally, the siphon degree adjusting device is adjusted back to the position of the normal working state.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
