Description

TECHNICAL FIELD

[0001] The utility model relates to chemical equipment technical field especially relates to a kind of steel lining tetrafluoro distillation still body. BACKGROUND

[0002] The four-fluorine layer inlaid in the inner wall of the distillation still body is to enhance its corrosion resistance. The four-fluorine material has strong chemical inertness and can resist corrosion of almost all strong acids, strong alkalis and organic solvents, avoiding corrosion and damage of the medium to the inner wall of the still body. It also has insulation, which can improve the safety of the equipment. The patent document with the patent number CN218686418U discloses a large-diameter steel lining four-fluoro distillation still, which includes a tank body and other structures. The distance between the flange and the first reinforcing rib is adapted to the diameter of the bearing basket to enable the bearing basket to be installed without bending during the process of falling vertically from the upper port of the tank body along the two symmetrical first channels to the flange. This makes the edges of the bearing basket placed on the flange flat and fit on the flange, preventing the material placed on the bearing basket from entering the bottom of the tank body and improving the distillation effect.

[0003] However, the above-mentioned distillation still has certain defects. The top of the bearing basket is used to place the material to be distilled. When the bearing basket is replaced with the material to be distilled, the top surface of the bearing basket needs to be cleaned. Since the bearing basket is directly inserted into the lap on the flange, it is troublesome to clean the top surface of the bearing basket. The entire distillation still cover needs to be opened, and the bearing basket needs to be pulled out for cleaning. The whole process is tedious and time-consuming. SUMMARY

The inner wall of the distillation still is provided with a four-fluoro layer.

[0007] The inner wall of the distillation still is fixedly provided with a recess at the bottom. The top of the recess is used to hold the distillation liquid. The bottom center of the recess is provided with a drain valve. The drain valve is used to control the discharge of waste distillation liquid.

[0008] The horizontal column is rotatably connected above the recess in the inner cavity of the distillation still. One end of the horizontal column is fixedly provided with a bearing basket. The top of the bearing basket is used to store the material to be distilled. The other end of the horizontal column is provided with an angle maintaining assembly, which can turn the top surface of the bearing basket downward, facilitating the cleaning of the dirty surface of the bearing basket.
