Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a raw material distiller for chemical industry. Background Art

[0002] Chemical industry refers to the chemical industry. Any use of chemical methods to change the composition or structure of substances, or to synthesize new substances, belongs to chemical production technology, that is, chemical process. The resulting products are called chemicals or chemical products. In the process of chemical production, chemical raw materials are usually distilled, and at this time a distiller is needed for distillation.

[0003] The existing distillation technology is a single distillation and cannot be multi-stage distillation. Since different components in the mixture have different boiling points, the single-stage distillation cannot obtain a fraction with a higher density from the mixture and cannot improve the distillation efficiency. Utility Model Content

[0004] In view of the above problems existing in the existing chemical distillation, the present utility model is proposed.

[0005] Therefore, the utility model aims to provide a chemical raw material distiller, which solves the problem of multi-stage distillation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, a motor is fixedly provided on one side of the shell, a rotating shaft is fixedly provided on the output end of the motor, the rotating shaft is rotatably connected to the shell, the rotating shaft passes through two partitions, and blades are fixedly provided on the shaft rod walls.

[0009] Preferably, a collecting pipe is fixedly provided at the bottom of the secondary distillation zone and the tertiary distillation zone, a first collecting box is provided at the bottom of the collecting pipe, a second collecting box is provided at one end of one of the U-shaped tubes, and a switch valve is fixedly provided at the bottom of the collecting pipe.

[0011] Furthermore, a feed port and a discharge port are fixedly provided on a side wall of one side of the shell.

[0012] Preferably, a base is fixedly provided at the bottom of the shell.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model adopts a primary distillation zone, a secondary distillation zone and a tertiary distillation zone to distill the mixture, uses three U-shaped tubes to connect the separation zones to ensure that each zone is interconnected, and uses multi-stage distillation to separate the components of the mixture and improve the separation efficiency, so as to obtain a higher purity fraction. At the same time, after obtaining a higher purity fraction, the multi-stage classification reduces the process and cost of subsequent processing, and the energy consumption in the multi-stage distillation process is small and the impact on the environment is small.

[0015] 2. The utility model adopts three pressure regulators to adjust the pressure in the primary distillation zone, the secondary distillation zone and the tertiary distillation zone. The accuracy of pressure control is crucial to the separation efficiency and product quality of multi-stage distillation. At the same time, in order to ensure better gasification of the mixture, a motor-driven rotating shaft and paddles are provided on one side of the shell to stir the mixture and fractions in the primary distillation zone, the secondary distillation zone and the tertiary distillation zone to fully gasify them.
