Oil-water separating apparatus

Abstract

A provided oil-water separating apparatus is used to remove oil of oil water in an oil-water container, and comprises an oil pump, an oil suction port, a floating body and an oil collection device; the oil pump is fixedly disposed on the oil-water container or the ground, the oil suction port is arranged on the floating body, an inlet and an outlet of the oil pump are respectively connected with the oil suction port and the oil collection device via pipelines, the floating body floats on the liquid surface of oil water, and the oil suction port is arranged at the oil layer of the oil water. According to the provided oil-water separating apparatus, the floating body and the oil pump are separated, shaking of the floating body on the liquid surface because of shaking of the pump body is eliminated, and the floating body can stably float on the liquid surface of the oil water, so that the water content in the oil sucked by the oil pump is effectively reduced; because the oil pump is installed on the oil-water container or the ground, safety accidents caused by long-term immersing of a cable in the oil water is avoided; and the oil pump can employ a gas driving manner, so that the usage safety of the oil pump is further improved.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to an oil-water separation device. Background technique [0002] In the cooling water supply system of the rolling mill in the metallurgical industry, the general water treatment system is to collect the water used for cooling the rolling mill in the sedimentation tank to precipitate scale, slag, and oil, and then pump the settled water to the cooling water after being purified by the filter. The cooling tower enters the clean water supply tank, and the water in the clean water supply tank is repeatedly supplied to the rolling mill, using this circulation method to achieve the purpose of saving water. [0003] After the cooling water passes through the cooling mill equipment, the oil in the lubrication system of the equipment is often brought into the water. The oil not only pollutes the water quality, but also affects the filtering effect of the filter. Therefore, the ...

Problems solved by technology

[0006] In actual use, due to the flow of water in the sedimentation tank 5' and the force of the floating bucket oil suction unit when absorbing oil, the oil suction port is unbalanced, and what is often sucked up is water instead of oil floating on the water surface. The thickness of the oil is variable, the height of the suction port needs to be adjusted frequently, and it is inconvenient to adjust the equipment in the sedimentation tank; the lift of the oil suction machine is low, and the oil-water mixture can only be sucked to the second equipment layer 52', and the collected oil is manually lifted to the ground 6' or pumping up again, it is inconvenient and increases the labor force; and the motor of this device has been used for a long time in the open air and in an environment with serious oil pollution, and there are potential safety hazards in the long-term immersion of the cable in oily water, so the use effect has not been ideal.
