Description

Technical Field

[0001] The utility model relates to the technical field of oil mill waste water recovery, in particular to an oil mill waste water recovery device. Background Art

[0002] After the metal plate is ground and polished by an oil mill, the grinding oil and metal powder on the surface of the oil-ground metal plate are removed by high-pressure gas spraying. However, there will still be a layer of oil film on the surface of the metal plate. Before the metal plate is sent to the next process, it needs to be cleaned with hot water or chemical solutions to remove the oil film on the surface of the metal plate. In the process of cleaning the oil film on the surface of the metal plate, a large amount of wastewater will be generated. The main components of the wastewater are metal powder, grinding oil and water. If these wastewaters are discharged, it will cause pollution and waste of raw materials. The commonly used recycling method is to precipitate the wastewater and separate the metal powder, while the grinding oil and water are separated by an electric oil-water separation mechanism, thereby realizing the recovery of the oil mill wastewater.

[0003] At present, the oil-water separation mechanism used to separate oil and water in grinding machine wastewater is mostly directly fixed on the upper side of the grinding machine wastewater storage tank when in use, and then the separation disk and scraper in the oil-water separation mechanism cooperate to realize the convenient separation of oil and water. Under the above installation method, although the oil-water separation mechanism can ensure the normal separation of oil and water in the grinding machine wastewater, the oil-water separation mechanism cannot be flexibly raised or lowered according to the height of the liquid level in the grinding machine wastewater storage tank due to its fixed installation position. At the same time, in the later stage of oil-water separation, the oil-water separation mechanism cannot be flexibly moved and adjusted according to the position of the oil in the grinding machine wastewater storage tank, resulting in poor flexibility in the use of the oil-water separation mechanism in the grinding machine wastewater recovery process and low oil-water separation efficiency.

When the grinding oil on the separation plate passes through the drainage groove, the grinding oil adhering to the separation plate will be scraped off by the scraper plate. The scraped grinding oil will flow into the oil collecting box through the drainage groove for centralized storage. The oil collecting box is equipped with an oil drain pipe to realize the timely discharge of the oil in the oil collecting box.

[0010] Furthermore, an operation panel is installed on the upper part of one side wall of the box body, and the operation panel is electrically connected to the electric slide rail 1, the electric slide rail 2, the electric telescopic rod and the oil-water separation mechanism.

[0012] Furthermore, a drain pipe is installed at the water outlet of the box, and the drain pipe is provided with a valve.

[0016] Furthermore, the second electric slide rail is connected to the mounting plate by bolts, and the hanging plate is connected to the second electric slide rail and the oil-water separation mechanism by bolts.

[0017] By adopting the above technical solution, the second electric slide rail is mainly used to realize the flexible movement of the oil-water separation mechanism in one direction in the horizontal plane, while the first electric slide rail is mainly used to realize the flexible movement of the oil-water separation mechanism in the other direction in the horizontal plane.
