Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, and in particular relates to an oil-water separator with a scraper. Background Art

[0002] Oil-water separators often use a filter structure to separate oil and water. During the filtering process, impurities gradually accumulate, which will reduce the filtering effect of the filter. Therefore, it is necessary to remove impurities from the filter or clean the mesh, which will increase the workload of device maintenance. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides an oil-water separator with a scraper.

[0004] The utility model can remove the oil in the oily water by scraping.

[0005] The technical solution provided by the utility model is as follows:

[0006] An oil-water separator with a scraper, comprising:

[0007] A cavity, wherein the bottom of the cavity is connected to an oil outlet;

[0008] A cylinder is fixedly arranged in the cavity, the upper end of the cylinder is open and is provided with a plurality of horizontal scrapers, a partition is vertically arranged in the middle of the cylinder, the height of the partition is lower than the height of the cylinder, the cylinder is connected to a liquid inlet pipe on one side of the partition, and the cylinder is connected to a liquid outlet pipe on the other side of the partition, and the liquid inlet pipe and the liquid outlet pipe respectively pass through the cavity wall of the cavity.

[0009] Based on the above technical solution:

[0010] The partition can ensure that the oil and water on the water inlet side pass through the area where the scraper is located before entering the water outlet side;

[0011] The scraper can be set to scrape the oil on the top of the oil and water away from the water.

[0012] Furthermore, a motor is fixedly arranged on the outer surface of the top wall of the cavity, and the output shaft of the motor is fixedly connected to a rotating shaft, which penetrates the top wall of the cavity and extends into the opening of the cylinder, and each scraper is fixedly arranged.

[0013] Based on the above technical solution, the scraper can be driven to rotate by the motor to scrape the oil on the upper part out of the cylinder.

[0014] Furthermore, each scraper is in the shape of an elongated strip, one end of which is fixedly connected to the rotating shaft, and the other end of which extends out of the edge of the upper end surface of the cylinder.

[0015] Based on the above technical solution, the oil in the upper part can be scraped out of the cylinder more fully.

[0016] Further:

[0017] The lower part of the end of each scraper is provided with a slope edge inclined toward the rotating shaft;

[0018] Correspondingly, the upper end surface of each cylinder has a groove extending from outside to inside;

[0019] A gap is arranged between the slope edge and the slope opening.

[0020] Based on the above technical solution, the obstruction of the cylinder wall at the upper end of the cylinder to the oil scraping can be reduced, so that the upper oil can be scraped out of the cylinder more fully.

[0021] Further:

[0022] The rotating shaft is arranged along the axial direction of the cylinder;

[0023] The extension direction of each scraper is away from the axis of the rotating shaft.

[0024] Based on the above technical solution, the scraper can push the oil outward when rotating.

[0025] Specifically, the height of the lower edge of the groove is higher than the height of the partition.

[0026] Specifically, a distance is provided between the outer wall of the cylinder and the inner wall of the cavity.

[0027] Specifically, the bottom surface of the cylinder is fixed to the bottom wall of the cavity through a plurality of fixed support columns.

[0028] Beneficial effects of the utility model:

[0029] The utility model scrapes the oil floating on the upper part away from the water by scraping, thereby reducing the use of the filter screen or the membrane, and correspondingly reducing the maintenance or replacement operation of the filter screen or the membrane.

[0035] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0036] Example 1

[0037] like Figure 1 As shown, the oil-water separator with a scraper comprises: a cavity 1, the bottom of the cavity 1 is connected to an oil outlet 3; a cylinder 2 fixedly arranged in the cavity 1, the upper end of the cylinder 2 is open, and a plurality of horizontal scrapers 4 are arranged, a partition 5 is vertically arranged in the middle of the cylinder 2, the height of the partition 5 is lower than the height of the cylinder 2, the cylinder 2 is connected to a liquid inlet pipe 6 on one side of the partition 5, and the cylinder 2 is connected to a liquid outlet pipe 7 on the other side of the partition 5, and the liquid inlet pipe 6 and the liquid outlet pipe 7 respectively pass through the cavity wall of the cavity 1. A spacing is set between the outer wall of the cylinder 2 and the inner wall of the cavity 1 for the oil to flow. In one embodiment, the liquid inlet pipe 6 and the liquid outlet pipe 7 are respectively arranged at the bottom of the cylinder 2. Based on this technical solution, the oil on the upper part of the oil and water can be scraped away from the water by setting the scraper.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1 As shown, a motor 8 is fixedly arranged on the outer surface of the top wall of the cavity 1, and the output shaft of the motor 8 is fixedly connected to a rotating shaft, which passes through the top wall of the cavity 1 and extends into the opening of the cylinder 2, and the scrapers 4 are evenly fixedly arranged around the circumference thereof.

[0040] Example 3

[0041] On the basis of Example 1, Figure 1 As shown, each scraper 4 is in the shape of a long strip, one end of which is fixedly connected to the rotating shaft, and the other end of which extends out of the edge of the upper end surface of the cylinder 2. Based on the above technical solution, the oil on the upper part can be scraped out of the cylinder more fully.

[0042] Example 4

[0043] On the basis of Example 1, the rotating shaft is arranged along the axial direction of the cylinder 2. Figure 2 As shown, the extension direction of each scraper 4 is away from the axis of the rotating shaft. The motor 8 drives the scraper 4 to rotate, and the rotation direction is that the scraper 4 pushes the oil outward. Based on this technical solution, the scraper can push the oil outward when rotating to separate the oil and water.

[0044] Example 5

[0045] On the basis of Example 1, Figure 1 As shown, the lower part of the end of each scraper 4 is provided with a slope 9 inclined toward the rotating shaft. Correspondingly, the upper end surface of each cylinder 2 has a groove 10 from outside to inside. A gap is provided between the slope 9 and the groove 10. The height of the lower edge of the groove 10 is higher than the height of the partition 5. Based on this technical solution, the obstruction of the cylinder wall at the upper end of the cylinder to the oil scraping can be reduced, so that the upper oil can be scraped out of the cylinder more fully.

[0046] Example 6

[0047] Based on the above embodiments, Figure 1 As shown, the bottom surface of the cylinder 2 is fixed to the bottom wall of the cavity 1 through a plurality of support columns 11 fixedly arranged around the circumference, so as to support and fix the cylinder.

[0048] The oil-water separator with a scraper provided by the utility model is used to separate oil and water:

[0049] The oil and water can be introduced from the liquid inlet pipe 6 at a relatively low speed continuous flow, and the oil in the oil and water passes through and is concentrated in the area where the scraper 4 is located, and is scraped by the scraper 4 to the outside of the cylinder 2, thereby achieving separation.

[0050] Alternatively, valves may be provided on the liquid inlet pipe 6 and the liquid outlet pipe 7, and the valves may be closed after the oil and water are pumped in by a pump, and the oil and water are allowed to stand in the cylinder 2 to separate into layers, and then the motor may be started to scrape the oil near the upper surface to the outside of the cylinder 2 by the scraper 4. Then, the oil and water are intermittently replenished from the liquid inlet pipe 6, and then scraped and separated after standing.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form.
