Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oil-water separation technology, and specifically relates to an oil-water separator. Background Technology
[0002] An oil-water separator is a machine that separates oil and water. Due to environmental protection requirements, wastewater generated by ships and machinery that is discharged into rivers, lakes, and seas must be treated and requires the use of oil-water separators. With the progress of society, oil-water separators have been widely used in pharmaceuticals, chemicals, catering, schools, hospitals and other places.
[0003] Current oil-water separators have low efficiency during use due to the small surface area of the oil suction equipment. A single oil separation process takes more than 48 hours and consumes a lot of energy. In view of the problems exposed in the use of current oil-water separators, it is necessary to improve and optimize the structure of the oil-water separator. Therefore, we propose an oil-water separator. Summary of the Invention

[0007] In the above-mentioned oil-water separator, the separation zone is located at the side end of the water collection zone, and a baffle is provided between the separation zone and the mixing zone. The upper end of the baffle is provided with a water passage groove for oil to enter the separation zone.
[0008] In the aforementioned oil-water separator, a mounting housing is provided on the separator body, and the mounting housing is mounted on the separator body via a hinge.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0016] like Figure 1 , Figure 2 As shown, this oil-water separator includes a separator body 1 and a tank for holding an oil-water mixture. A separation chain 2 is provided between the separator body 1 and the tank. The separator body 1 is provided with a rotating drive wheel 3 that is driven by the separation chain 2. The drive wheel 3 has an oil passage space that communicates with the outside. A scraper 4 is fixedly provided on the separator body 1 and at the lower end relative to the drive wheel 3. The drive wheel 3 has several liquid passage holes 5 for passing liquid. The separator body 1 is provided with a mixing zone 6 for collecting liquid, a water collection zone 7 for collecting water, and a separation zone 8 for separation. A buffer section 9 for liquid buffering is provided at the upper end of the mixing zone 6.
[0017] To elaborate further, a baffle 10 is provided between the mixing zone 6 and the water collection zone 7, and a water passage trough 12 for supplying water into the water collection zone 7 is provided at the lower end of the baffle 10.
[0018] To elaborate on the working principle, one end of the separating chain belt 2 is placed inside the tank containing the oil-water mixture, and the other end is fitted onto the drive wheel 3. As the drive wheel 3 rotates, the oil-water mixture adheres to it. With the drive wheel 3's rotation, some liquid oil-water enters the interior of the drive wheel 3 through the liquid passage hole 5 and flows out onto the scraper 4, then into the mixing zone 6. Solid oil-water adheres to the drive wheel 3. Due to the rotation of the drive wheel 3, the scraper 4 scrapes the oil-water mixture on the drive wheel 3. Both enter the mixing zone 6 from the scraper 4. Due to the density difference between oil and water, the water layer sinks to the bottom and flows from the water passage 12 at the lower end of the baffle 10 to the water collection zone 7, while the oil layer rises to the top and flows from the water passage 12 at the upper end of the baffle 21 to the separation zone 8.
[0019] To elaborate further on the buffer section 9, the oil flows from the scraper 4 into the mixing zone 6, where waves are generated on the liquid. Through the action of the buffer plate, the impact of the oil on the liquid in the mixing zone 6 is greatly reduced.
[0020] To elaborate further, the separation zone 8 is located at the side end of the water collection zone 7, and a baffle 2 11 is provided between the separation zone 8 and the mixing zone 6. The upper end of the baffle 2 11 is provided with a water passage trough 12 for the oil supply body to enter the separation zone 8.
[0021] To elaborate further, the separator body 1 is provided with a mounting housing 13, which is mounted on the separator body 1 via a hinge.
[0022] To elaborate further, the water collection area 7 is connected to a water collection pipe 14, and the separation area 8 is connected to an external oil pipe 15.
[0023] To elaborate further, the separator body 1 is equipped with a drive motor that drives the transmission wheel 3 for transmission.
[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0025] Although this document frequently uses terms such as separator body 1, separation chain 2, drive wheel 3, scraper 4, liquid passage hole 5, mixing zone 6, water collection zone 7, separation zone 8, buffer section 9, baffle one 10, baffle two 11, water passage trough 12, mounting housing 13, water collection pipe 14, and external oil pipe 15, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
