Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, in particular to an oil-water separation device capable of separating light oil and heavy oil. Background Art

[0002] When preparing certain drugs (such as vaseline, etc.), water and oil need to be separated to ensure the purity and effectiveness of the drugs. The methods for achieving oil-water separation usually include physical methods and chemical methods. Physical methods can use principles such as precipitation, filtration, and centrifugation for separation, while chemical methods may involve adding specific chemical reagents to promote the separation process. In general, medical oil-water separation plays an important role in the medical process, which can help medical staff obtain the required pure water or oil and ensure the smooth progress of medical operations.

[0003] A document with a publication number of (CN218485218U) is retrieved and discloses a novel oil-water separator, comprising: a jacket is arranged on the outer periphery of an inner cylinder of the oil-water separator, a cooling gap is formed between the inside of the jacket and the outer periphery of the inner cylinder of the oil-water separator; a chilled water or cooling water inlet is connected to the lower end of the jacket; a chilled water or cooling water outlet is connected to the upper end of the jacket; and a support seat is arranged on the outer periphery of the jacket.

[0004] The above device allows cooling water or chilled water to be introduced into the jacket when the oil-water mixture enters the cavity of the separator, thereby rapidly reducing the temperature of the oil-water mixture, thereby further effectively separating the oil-water mixture. However, the oil-water separation process takes time. During the oil-water separation period, the lack of cold water in the device will cause the temperature to rise rapidly due to the medium exchange principle, making it impossible to cool the oil-water mixture. As a result, the above device needs to be continuously supplemented with cooling water, and the cooling and sedimentation separation takes a long time.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0011] As a preferred embodiment of the utility model, the centrifugal assembly includes a driving motor and a stirring block, the driving motor is fixedly connected to the bottom of the box, and the stirring block is fixedly connected to the output shaft of the driving motor.

[0012] As a preferred embodiment of the utility model, the stirring block is a drooping sheet structure that is flat on the top and convex on the bottom, and the lower side of the stirring block is an arc-edge fan.

[0013] As a preferred embodiment of the utility model, a first pipe and a second pipe are provided at one end of the discharge pipe, one end of the first pipe and the second pipe are fixedly connected to the discharge pipe, the other end of the first pipe and the second pipe are fixedly connected to an extraction port, and the feed pipe, the first pipe, the second pipe and the sewage pipe are all provided with valves.

[0014] As a preferred embodiment of the present utility model, the condenser is closely wound around the outer wall of the box body, and both ends of the condenser are connected to the condensing device.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. An oil-water separation device capable of separating light oil and heavy oil, wherein the condenser increases the heat exchange area by winding with the outer wall of the box, and at the same time, the box is continuously cooled by the condenser to rapidly reduce the temperature of the oil-water mixture, thereby further effectively separating the oil-water mixture, and avoiding the rapid increase in temperature caused by the medium exchange principle due to the lack of water in the device, which makes it impossible to cool the oil-water mixture. At the same time, the water content of the oil-water mixture inside the box is reduced by external heat exchange and cooling, thereby reducing the time for oil-water separation.

[0017] 2. This is an oil-water separation device that can separate light oil and heavy oil. It drives the stirring block to rotate by a driving motor and drives the oil-water mixture to follow the rotation to generate centrifugal force, and physically separates the water as the continuous phase from the heavy oil and light oil as the dispersed phase. The greater the density difference between the dispersed phase and the continuous phase, the easier it is to separate the two phases. Similar to the situation in the gravitational field, under the condition of a certain density difference between the two phases, the larger the particle diameter of the dispersed phase, the greater the speed difference between the two phases running in the opposite direction when the equilibrium state is reached in the gravitational field, thereby quickly separating.

[0018] 3. This is an oil-water separation device that can separate light oil and heavy oil. The servo motor drives the transmission block to rotate through the output shaft, and the transmission block drives the scraper to rotate and rub the inner wall of the box, so that the excess oil flows to the bottom of the box through the scraper and the guide groove on the scraper, and is discharged through the drain pipe at this time to prevent the oil from accumulating in the box for a long time and causing quality change, which will cause pollution to the oil separated from the oil and water.
