Description

Emulsion floating oil absorption device

technical field

The utility model belongs to a device for separating and recovering the dirty oil on the surface of the emulsion of rolling equipment or the surface of industrial sewage, in particular to an absorbing device for the floating oil of the emulsion.

Background technique

Domestic cold-rolled steel rolling equipment mostly adopts mechanical oil scraper to deal with the floating oil in the emulsion system. This equipment cannot adjust the thickness of the absorbed oil layer by itself according to the change of the liquid level. It is necessary for the equipment operator to adjust the relative position of the oil scraper according to the change of the liquid level. At the immersion position of the liquid surface, the oil floating on the surface is scraped off by the reciprocating operation of the oil scraper. The oil removal effect is greatly affected by the dynamic liquid level change, and the oil removal amount is unstable, so the effect is not ideal.

Utility model content

The purpose of this utility model is to provide an emulsion oil slick absorption device, which can not only separate and recycle the surface oil slick of water and aqueous solution, but also can adjust the suspension height with the change of liquid level to realize the effective separation and absorption of slick oil. The structure is reasonable and compact, the manufacturing and maintenance cost is low, the installation is convenient, and the operation is convenient.

The purpose of this utility model is achieved in this way: an emulsion oil slick absorbing device, three external closed buoys are fixed in a triangle connection through the connection frame, and are located in the triangle connection frame through three connections fixed to the triangle connection frame. The plate is fixed to the sleeve at the same time, and the three built-in buoys located in the triangular connection frame are open on the top surface and the through holes on the bottom surface are connected to each other through the three-way connection pipe, and the valve is installed on the outlet of the three-way connection pipe. The through-holes on the side walls of the three built-in buoys communicate with the corresponding through-holes on the casing wall through connecting pipes. Both ends of the casing are provided with reduced-diameter holes, and the upper end is provided with a collection pipe with a funnel and a reduced-diameter hole of the casing. Dynamic sealing fit, the lower end of the collection tube is fixedly fitted with the sleeve, and the through hole provided on the collection tube matches the inner cavity of the sleeve.

The utility model is an oil slick treatment equipment structure designed based on the principle of specific gravity separation. According to the thickness of the floating layer of floating oil, the suspension height of the external closed buoy can be adjusted by adjusting the counterweight of the external closed buoy to realize the floating oil. effective separation and absorption. Since the three external closed buoys adopt a three-point symmetrical structure design, the cavities of the three buoys are relatively independent, not only can reach the level of the reference collection pipe and the liquid level, but the external closed buoys always maintain the same level as the liquid level during work. fixed position, the relative position is constant. The built-in buoy also adopts a three-point symmetrical structure design. The cavities of the three built-in buoys are connected to each other through a three-way connecting pipe, and the outlet of the three-way connecting pipe is connected to a vacuum pump through a valve and a pipeline. In actual work, three built-in buoys store the slick oil collected by the collecting pipe, and float up and down during the process of self-weight change. During the floating process caused by the floating oil stored in the built-in buoy, the casing floats accordingly. The through hole on the collecting pipe is located within the range of the inner cavity of the casing, which can ensure that the work of the built-in buoy to collect floating oil is within the predetermined floating stroke. When the built-in buoy stores floating oil and causes the floating process of self-weight change, the through hole on the follow-up collection pipe exceeds the range of the inner cavity of the casing. At this time, the continuous collection of floating oil is automatically blocked. It ensures that the work of the built-in buoy is within the predetermined floating stroke, and the operator can turn on or off the vacuum pump arbitrarily according to the needs of degreasing. The utility model can not only separate and recycle the floating oil on the surface of water and aqueous solution, but also can adjust the suspension height to realize the effective separation and absorption of the floating oil according to the change of the liquid level. The utility model has reasonable and compact structure, low manufacturing and maintenance cost, convenient installation and convenient operation .
