Description

Technical Field

[0001] The utility model relates to the technical field of coal tar processing equipment, in particular to an oil-water separator for coal tar processing. Background Art

[0002] Coal tar processing requires the use of a variety of processing equipment, including oil-water separators, which are mainly used to separate water and oil in coal tar. The density difference between water and oil is utilized to separate the water and oil in the separator through gravity sedimentation and other methods. The heavier water sinks to the bottom and the lighter oil floats on top, thus achieving oil-water separation.

[0003] The existing oil-water separators for coal tar processing have the following problems during use: the water and oil mixture in the coal tar usually enters the tank directly through the liquid inlet at the top of the tank and is left to stand. That is, gravity sedimentation causes the water and oil to separate into layers in the separator, with the heavier water sinking to the bottom and the lighter oil floating on top, thereby achieving oil-water separation. It takes a long time for the water and oil mixture to mix fully and stand, which is not conducive to the rapid stratification and separation of the water and oil mixture. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an oil-water separator for coal tar processing, which solves the problems raised in the background art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an oil-water separator for coal tar processing, comprising a separation tank; a feeding mechanism, arranged at the upper end of the separation tank; a discharging mechanism, arranged at the lower end of the separation tank, the separation tank comprising a tank body, an inner wall of the tank body having an oil outlet, an outer wall of the tank body having an oil outlet control valve fixedly installed at the oil outlet opening, a spiral guide cover fixedly connected above the inner wall of the tank body, the feeding mechanism comprising a feeding guide cover fixedly connected to the upper opening of the tank body, the discharging mechanism comprising a sealing cover fixedly connected to the lower opening of the tank body, three through holes being horizontally equidistantly provided between the upper and lower side walls of the sealing cover, a stirring paddle being arranged above the middle through hole, and a water outlet control valve being fixedly installed on the bottom wall of the sealing cover and at the opening below the two through holes on both sides.

[0006] As a further solution of the present invention: four mounting seats are fixedly connected at equal angles above the annular outer wall of the tank body, the top wall of the mounting seat is provided with a groove, and the bottom wall of the groove is provided with a mounting hole, and a through groove is provided in the middle of the front end of the inner wall of the tank body, and an observation window is fixedly installed in the through groove.

A driving shaft is provided on the top of the driving motor, and the driving shaft passes through the middle through hole and is fixedly connected to the stirring paddle above.

[0008] As a further solution of the present invention: a feed port is provided at the center of the inner top wall of the feed guide cover, a guide pipe is fixedly installed on the outer top wall of the feed guide cover at the opening of the feed port, and a connecting flange is fixedly connected to the opening above the guide pipe.

[0010] 1. In the utility model, a structure for assisting the mixing and stratification of the water and oil mixture is provided, that is, a spiral guide cover is provided at the top of the tank body in conjunction with the feed end, so that the water-oil mixture entering the tank body and the chemical reagent that can promote oil-water separation can be discharged after spiral guidance through the spiral guide cover. In conjunction with the stirring mechanism at the bottom of the tank body, the mixing of the chemical reagent and the water-oil mixture can be promoted.
