Description

A stirring paddle scraper device for demulsification

technical field

The utility model relates to the technical field of demulsification stirring paddle cleaning, in particular to a demulsification stirring paddle scraper device.

Background technique

Emulsification is an important indicator of lubricating oil used in steam turbines. During the operation of steam turbines or hydraulic turbines, water or water vapor may enter due to abnormal system, thereby emulsifying the oil. In order to resist water to oil Due to the emulsification caused, the turbine oil must have a certain demulsification ability to ensure that the oil can be used in the equipment for a long time and play the role that the oil should play. Power plants generally use the degree of emulsification of turbine oil as an important basis for testing whether the oil is qualified. Usually, the detection of demulsification degree of oil products adopts the instrument method. According to the standard, the test condition is constant temperature 54°C±1°C, add 40mL deionized water and 40mL oil product to be tested in the measuring cylinder, stir for 5min after constant temperature to form an emulsion, and then Artificially scrape the emulsified layer on the stirring paddle into the graduated cylinder, and measure the time required for the separation of the emulsion (that is, when the volume of the emulsified layer is not greater than 3mL). After standing still for 30 minutes, if the emulsion is not completely separated, or the emulsion layer is not reduced to 3mL or less, record the volumes of the oil layer, emulsion layer and water layer at this time.

This method of manual operation by the experimenter has certain disadvantages. The operation of manually scraping off the emulsion will inevitably leave some emulsion on the stirring paddle, resulting in the lack of emulsion in the measuring cylinder, affecting the accuracy of the experiment. Moreover, there is a large amount of oil-water mixture or emulsion on the stirring paddle, which will cause certain troubles during cleaning, waste a large amount of cleaning liquid (petroleum ether), and bring certain economic expenditures. Based on this, we designed a paddle scraper device to reduce the residue of emulsion on the paddle.
