Description

Technical Field

[0001] The utility model belongs to a fine chemical distillation device and relates to a distillation condensate layer separation device. Background Art

[0002] Under existing technical conditions, the recovery of mixed solutions in fine chemical production usually involves standing the condensate after distillation to separate into layers, and then manually opening and closing the valves through the sight glass on the bottom pipeline to introduce them into different storage tanks, thereby achieving the recovery of two different solutions. This operation not only increases equipment and manpower, but also causes errors caused by manually opening and closing the valves through the sight glass, and the two solutions are not completely separated.

A connecting seat 8 is fixed to the side wall of the cylinder 1, and is fixed to the support column of the workshop through the connecting seat 8. The distillation condensate inlet 2 is connected to the condenser discharge port through a pipeline.

[0012] The cylinder 1 is provided with an observation mirror 9, which is located below the inner tube 7 and above the connection between the lower part of the bypass tube 5 and the side wall of the cylinder 1.

[0013] Use: Add the heavy component material to the heavy component pre-addition inlet 3, and the liquid level is higher than the connection between the lower part of the bypass pipe 5 and the side wall of the cylinder 1. The observation mirror 9 is transparent, and the liquid level in the cylinder 1 can be checked. Of course, the valve of the inlet pipe of the heavy component pre-addition inlet 3 can also be set as a solenoid valve, and an electronic liquid level gauge can be set on the cylinder 1. The electronic liquid level gauge and the solenoid valve are linked to control. When the liquid level is not above the connection between the lower part of the bypass pipe 5 and the side wall of the cylinder 1, the valve is closed and the heavy component material is stopped. When there is a certain level of heavy component material in the cylinder 1, the distillation condensate enters from the distillation condensate inlet 2, first enters the inner tube 7, and then flows from the inner tube 7 to the cylinder 1.
