Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1-3, a multistage oil-dirt separator comprises a solid filter 1 and an oil-dirt separation barrel 2, wherein the bottom of the solid filter 1 is communicated with the oil-dirt separation barrel 2 through a flow guide pipe 3, and the flow guide pipe 3 is of a liquid-sealed flow guide elbow structure.

1 top of solid filter is equipped with water inlet 5 and carries and draw handle 6, be equipped with three-layer filter screen 101 in the solid filter 1 from top to bottom, filter screen 101's aperture reduces gradually from top to bottom, is 2.5cm, 1.5cm, 0.5cm in proper order. And (3) carrying out first standing separation on the liquid sewage after the solid garbage is removed, and taking out the screen for cleaning by using a lifting handle 6 at the top.

The oil stain separation barrel 2 comprises a first separation tank 201, a second separation tank 202 and a third separation tank 203, the first separation tank 201 and the second separation tank 202 are separated by a first tank wall 204, the second separation tank 202 and the third separation tank 203 are separated by a second tank wall 205, the third separation tank 203 and the first separation tank 201 are separated by a third tank wall 206, a draft tube 3 is communicated with the first separation tank 201, a water outlet 207 is formed in the third separation tank 203, communication bent tubes 4 are arranged on the first tank wall 204 and the second tank wall 205, liquid can sequentially flow from the first separation tank 201 to the third separation tank 203, and two ends of each communication bent tube 4 are respectively located at the bottom of the upper-stage separation tank and the upper part of the lower-stage separation tank. The bottom of the third tank wall 206 is provided with a switchable through hole 7 for communicating the first separation tank 201 and the second separation tank 202. A liquid level sensing device and a water inlet recognition device are arranged in the oil stain separation barrel 2, and a cleaning warning device is arranged on the outer wall of the oil stain separation barrel 2 and connected with the liquid level sensing device and the water inlet recognition device. The bottom of the oil stain separation barrel 2 is also provided with a heating device, and a temperature sensing device is arranged in the oil stain separation barrel 2 and is connected with the heating device. The top of the solid filter 1 is provided with a barrel cover 8, and the oil stain separation barrel 2 is internally provided with a plurality of oil absorption sponges.

The working process is as follows:

oily sewage such as water for a dish washer naturally flows into the sewage inlet pipe through the pipeline, flows into the solid filter under the action of gravity, and passes through the three-stage screen mesh with the gradually reduced pore diameter step by step, so that solid garbage such as vegetable leaves and food residues are effectively removed, the pipeline is prevented from being blocked, and odor generated by fermentation of the solid garbage in liquid can be prevented.

After filtration, liquid oil stains are led into the first separation tank 201 through the flow guide pipe 3 at the bottom of the solid filter 1, the flow guide pipe 3 can effectively buffer water flow and has a liquid sealing effect, and a section of water column is reserved in the bent pipe, so that the odor of the oil stains can be effectively prevented from being emitted upwards and having an insect prevention effect. Because the density of oil is less than the density of water, the oil stain is kept stand and separated in the first separation pool 201, and a constant temperature device is used for heating, the oil floats on the upper layer of the water body, and the water body at the bottom enters the second separation pool 202 through the communication elbow 4. Similarly, the water at the bottom of the second standing separation in the second separation tank 202 flows into the third separation tank 203 through the communication elbow 4. During the process, the adsorption objects such as oil absorption sponge added in each separation pool continuously absorb the oil stains on the surface of the constant temperature liquid. After the three standing separations are completed, the purified water flows out through the water outlet 207 and the sewage treatment is completed.

When the cleaning warning device connected with the oil layer thickness detection device is on a red light, the oil stains on the upper layer can be cleaned in time and oil stain adsorption objects can be cleaned and replaced; when a fault occurs and the maintenance is needed, the water in the oil stain separating barrel can be quickly emptied for maintenance only by opening the through hole 7, the oil stain treatment efficiency is ensured, and the service life of the oil stain separator is greatly prolonged.

The oil stain separator has the characteristics of simple structure, no need of manual intervention, detachable cleaning, small size and mobility, so that the application scene is wider. The size of the barrel body is set according to the field situation, and the sizes of all parts in the barrel can be adjusted in proportion.
