Multifunctional intelligent distillation instrument

Abstract

The invention discloses a multifunctional intelligent distillation instrument. The distillation instrument comprises a shell, a support, heating devices and a cooling device, wherein the heating devices are a plurality of relatively independent heating units, and each heating unit comprises a heating jacket, a heating bar, a heating bowl and a distillation bottle; the heating bowl is arranged in a heating box, the open end of the upper part of the heating bowl is provided with a stove port, and the distillation bottle is arranged in the stove port; the heating jacket is fixed on the periphery of the heating bowl; and the distillation instrument is also provided with a measurement and control device, a temperature sensor is fixed on the top of each heating bowl and connected with a control circuit board through a signal wire and transfers heating temperature to a control chip on the control circuit board, and a liquid level sensor is fixed on a console and senses the liquid level state in a volumetric flask through an optical fiber. The instrument can be widely applied to distillation treatment of projects of volatile phenol, cyanide, ammonia nitrogen, Kjeldahl nitrogen, water in oil and the like in various chemical laboratories requiring distillation treatment in environment friendliness, disease control, water supply and drainage, colleges, research institutions, industrial enterprises and the like.

Description

technical field [0001] The invention relates to a pretreatment device for distillation experiments. Background technique [0002] Distillation is a common and important pretreatment method for laboratory separation and purification of liquid mixtures. Although the traditional distillation device can realize the basic distillation function, there are the following problems: [0003] 1. The traditional distillation device uses electric furnace wire to directly heat the retort bottle and connects a serpentine condenser at the steam outlet, which can easily cause the retort bottle to burst, resulting in short circuit, electric leakage, and endangering the personal safety of the operator. [0004] 2. Multiple samples cannot be distilled at the same time, only a single furnace and a single sample can be distilled. [0005] 4. During the distillation process, due to the uncontrollable temperature, uneven heating is likely to cause bumping and sample flushing. [0006] 5. The con...
