Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1: a kitchen waste slurry oil-water separator comprises a container 1 for receiving kitchen waste slurry, wherein the upper side of the container is an opening side, the whole container is circular, a sleeve 2 is arranged in the center of the container 1, the lower side of the sleeve 2 is fixed at the bottom of the container 1, and the upper side of the sleeve 2 is open; the sleeve is tubular and is arranged coaxially with the container.

The side wall of the container 1 is communicated with a liquid inlet pipe 3 for receiving an upstream part, the upstream part is solid-liquid separation equipment for separating residues from swill to obtain the swill mixed with vegetable oil, the liquid inlet pipe 3 extends through the side wall of the sleeve 2, and a first buffer net 21 is sealed at the opening side of the upper side of the sleeve 2; power equipment such as water pumps are connected in series to the liquid inlet pipe, and the liquid inlet pipe has an impact effect when entering the sleeve, and in order to prevent the turbulence of the impact effect from damaging an upper oil-water separation layer, a buffer net is arranged for blocking.

The circumferential part between the container 1 and the sleeve 2 is communicated with the downstream part through a drain pipe 5; the downstream part is a fermentation tank and is discharged to municipal sewage after fermentation treatment.

An oil collecting pipe 6 floating on the upper side of the slurry is arranged in the container 1, an oil inlet 61 is formed in the oil collecting pipe 6, and the oil collecting pipe 6 is communicated with the downstream part through an oil discharging pipe 4. The downstream part is an oil storage barrel and the like, and is used for processing and application in other fields.

The slurry in the container needs to be higher than the opening at the upper side of the sleeve, swill mixed with vegetable oil enters the sleeve, turns over upwards and then diffuses towards the periphery, and in the process of diffusing towards the periphery, the vegetable oil and water in the swill are separated under the action of an auxiliary agent. The oil density is small, the oil floats on the upper layer, is captured by the oil collecting pipe and is further collected through the oil discharging pipe communicated with the oil collecting pipe, the water on the lower layer is discharged through the water discharging pipe, and in order to achieve continuous operation, the flow speed of the liquid inlet pipe and the water discharging pipe is balanced.

As shown in fig. 1-2: the oil collecting pipe 6 is annular, the container 1 is circular, the outer ring side of the oil collecting pipe 6 is attached to the inner side wall of the container 1, and the oil inlet 61 is arranged on the inner ring side. The oil layer has edge adsorption effect, and the upper oil layer can automatically approach to the side of the container, so that the oil collecting pipe can collect oil to the maximum extent. The oil collecting pipe floats on the oil layer by means of the buoyancy of the oil collecting pipe.

The part of the liquid inlet pipe 3 extending into the sleeve is bent downwards by 90 degrees, the liquid outlet is downward, and a second buffer net 22 is arranged below the sleeve 2 corresponding to the pipe orifice of the liquid inlet pipe 3. The effect of first buffering net and second buffering net is the same, and the feed liquor pipe gets into the sleeve and leads to the impact force downwards through the bending mouth, further reduces the impact of solution to the upper oil reservoir.

The drain pipe 5 is communicated with the bottom of the container 1, the drain pipe 5 penetrates through the bottom of the container 1 and is provided with an extension section, and one end of the drain pipe 5 communicated with the container is a flaring side. The swill entering the container also has part of meal residues, and in the free settling process, the part of meal residues settle at the bottom of the container, and the meal residues at the bottom of the container are periodically cleaned.

The oil discharge pipe 4 is communicated with the oil collecting pipe 6 through a spiral hose 41. Because the velocity of flow between feed liquor pipe and the drain pipe has the error, in order to guarantee that the liquid level floats and causes the influence that the oil collecting pipe come-up descends, arrange through the spiral hose connection between oil pipe and the oil collecting pipe, the distance compensation that the oil collecting pipe fluctuate and bring can be compensatied to the extension function of spiral hose.

The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best understand the invention for and utilize the invention.
