DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of this patent will be clearly and completely described in conjunction with the drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this patent.

[0020] Please refer to Figure 1-2, this patent provides a technical solution: an integrated oil-water separation treatment device, including an oil-water separator 1. A water inlet pipe 2 is installed on the side wall of the oil-water separator 1, and the water inlet pipe 2 is connected to an external sewage pipeline;

[0021] The external oil-water mixture can enter the oil-water separator 1 through the water inlet pipe 2, and then the oil-water separation is carried out through the oil-water separator 1;

[0022] The oil-water separator 1 proposed in this article is a prior art. Its principle is to spray sewage from the internal diffusion nozzle. At this time, large oil droplets float on the top of the left oil collection chamber, and the sewage containing small oil droplets enters the corrugated plate coalescer in the lower part. Some oil droplets are polymerized into larger oil droplets in this part and reach the right oil collection chamber. The sewage containing smaller oil droplets passes through the fine filter to remove impurities in the water, and then enters the fiber aggregator in turn, so that the fine oil droplets are polymerized into larger oil droplets to be separated from the water. After separation, the clean water is discharged through the discharge port, and the dirty oil in the left and right oil collection chambers is automatically discharged through the solenoid valve. The dirty oil separated by the fiber aggregator is discharged through the manual valve;

[0023] The water inlet pipe 2 includes a water injection pipeline 21, a transition pipe 22 and an electric heating rod 23. One end of the water injection pipeline 21 is connected to the external sewage pipeline, the other end of the water injection pipeline 21 is installed with a transition pipe 22, the transition pipe 22 is connected to the input end of the oil-water separator 1, and a fixing seat 3 is installed on the inner wall of the transition pipe 22. An electric heating rod 23 is installed on the upper part of the fixing seat 3, and the electric heating rod 23 is electrically connected to an external power supply;

[0024] A connecting cylinder 4 is inserted and installed on the upper wall of the water injection pipeline 21, a scraping mechanism 5 is inserted and installed in the connecting cylinder 4, and the scraping mechanism 5 is attached to the inner wall of the water injection pipeline 21;

[0025] In order to prevent the internal grease from coagulating during the process of transporting the sewage into the oil-water separator 1, an electric heating rod 23 is provided in the water inlet pipe 2 of this device, so that it can heat the oil-water mixture, so as to achieve the purpose of preventing the grease in the oil-water mixture from solidifying, avoiding blocking the water inlet pipe 2 and affecting the subsequent grease treatment efficiency.

[0026] Specifically, the scraping mechanism 5 includes an electric control push rod 51, a fixing rod 52, a scraping ring 53 and a connecting frame 54. An electric control push rod 51 is installed on the side wall of the oil-water separator 1. The electric control push rod 51 is electrically connected to an external power supply. One end of a fixing rod 52 is installed at the output end of the electric control push rod 51. The cross section of the fixing rod 52 is L-shaped. The other end of the fixing rod 52 is installed with a connecting frame 54 through the upper wall of the water injection pipeline 21 through the connecting cylinder 4, and a scraping ring 53 is installed on the lower wall of the connecting frame 54;

[0027] Although simple heating can prevent its oil from solidifying, when the oil-water mixture passes through the water injection pipeline 21, an oil film will still form on the inner wall of the water injection pipeline 21. When the device stops running and the electric heating rod 223 stops heating, the oil film inside the water injection pipeline 21 will solidify, still affecting water injection.

[0028] Therefore, a oil scraping mechanism 5 is provided in this device, and the oil film is scraped off by the oil scraping ring 53 in the oil scraping mechanism 5.

[0029] Specifically, a water storage cavity 6 is formed in the inner cavity of the oil scraping ring 53. A nozzle 7 is inserted and installed on the lower wall of the oil scraping ring 53. The nozzle 7 is communicated with the water storage cavity 6. One end of a connecting pipe 8 is inserted and installed on the upper wall of the oil scraping ring 53, and the other end of the connecting pipe 8 penetrates through the side wall of the fixed rod 52 and is connected to an external pump.

[0030] When the oil scraping ring 53 cleans the inner wall of the water injection pipeline 21, the external pump can inject water into the water storage cavity 6 through the connecting pipe 8, and then the water flow will be sprayed onto the inner wall of the water injection pipeline 21 through the nozzle 7, improving the cleaning effect of the oil scraping ring 53.

[0031] Specifically, universal wheels 9 are installed at the four corners of the lower wall of the oil-water separator 1.

[0032] Since the oil-water separator 1 is heavy and inconvenient to move, universal wheels 9 are provided below the oil-water separator 1 in this device to facilitate the staff to adjust the position of the oil-water separator 1.

[0033] Specifically, a sleeve 10 is sleeved outside the water injection pipeline 21, and a heat insulation pad 11 is fitted and installed on the inner side wall of the sleeve 10.

[0034] When the electric heating rod 23 heats the oil-water mixture in the water injection pipeline 21, the water injection pipeline 21 will inevitably get hot. To prevent staff from being scalded by accidental contact, this device wraps the water injection pipeline 21 with the sleeve 10 and the heat insulation pad 11 to prevent the staff from coming into contact with the water injection pipeline 21.

[0035] Specifically, one end of a support rod 12 is installed on the inner side wall of the oil scraping ring 53, and the other end of the support rod 12 is installed with a collar 13. The collar 13 can be sleeved outside the electric heating rod 23, and the inner side wall of the collar 13 can be attached to the side wall of the electric heating rod 23.

[0036] The side wall of the electric heating rod 23 can be cleaned through the collar 13 to avoid the influence of the grease outside the electric heating rod 23 on the heating efficiency.

[0037] Working principle: The external oil-water mixture is transported to the water inlet pipe 2 by a pump, and then flows into the oil-water separator 1 through the water inlet pipe 2. Then, oil-water separation is carried out by the oil-water separator 1. In order to avoid the condensation of internal grease during the transportation of sewage to the oil-water separator 1, an electric heating rod 23 is arranged in the water inlet pipe 2 of this device, so that it can heat the oil-water mixture. And the fixed rod 52 is driven to move up and down by the electric control push rod 51, so that the oil scraping ring 53 cleans the inner wall of the water injection pipeline 21, so as to avoid the condensation of the oil-water mixture in the water inlet pipe 2 when transporting the oil-water mixture, and avoid causing the blockage of the pipeline and affecting the subsequent grease treatment efficiency.

[0038] For those skilled in the art, it is obvious that this patent is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this patent, this patent can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this patent is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this patent. Any reference signs in the claims should not be regarded as limiting the claims involved.
