Embodiment 1

[0021] Such as figure 1 Shown, a kind of laboratory twice distilled water device, comprises the first distillation bottle 1, the second distillation bottle 2, the first condensation pipe 3, the second condensation pipe 4 and the collecting bottle 5, the first distillation bottle 1 and the second distillation Bottles 2 are equipped with a water inlet and a steam outlet, wherein the first distillation bottle 1 has two water inlets, and the first condensation pipe 3 and the second condensation pipe 4 are respectively connected and docked with the first distillation flask 1 and the second distillation flask 2 , the first condensing pipe 3 and the second condensing pipe 4 have the same shape, and both have three orifices of cooling water inlet, cooling water outlet and distilled water outflow port, and the cooling water inlet, cooling water outlet and distilled water outflow port are sequentially from top to bottom Set, the outlet of distilled water is located near the bottom of ea...

Embodiment 2

[0024] The three-way joint is communicated with the cooling water outlet of the second distillation bottle 2, and there are eighty water flow pipes 8. All the other are with embodiment 1.

Embodiment 3

[0026] The water inner pipe is a serpentine spiral pipe, and the three-way joint 11 is connected to the water adding control valve while only communicating with the water outlet of the water bath dish 9 through a silicone tube, not connected to the cooling of the first distillation bottle 1 or the second distillation bottle 2 In the water outlet, the liquid level sensor 12 is not arranged in the first distillation bottle 1 either. The water adding control valve is a manual valve. All the other are with embodiment 1. During the distillation process, the replenishment of the first retort 1 is manually controlled. When the water level in the first retort 1 is very low or when the water temperature in the water bath 9 is close to 20° C., the water addition control valve can be manually operated to replenish water.

Abstract

The invention discloses a secondary distilled water device in a laboratory, which comprises a first distillation bottle, a second distillation bottle, a first condensation pipe, a second condensation pipe and a collection bottle, and the first distillation bottle and the second distillation bottle are equipped with The water inlet and steam outlet, the first condensing pipe and the second condensing pipe are respectively connected and docked with the first distillation bottle and the second distillation bottle, the distilled water outlet of the first condensing pipe is connected with the second distillation bottle, and the distilled water of the second condensing pipe The outflow port is communicated with the collecting bottle, and the collecting bottle is placed in a water bath dish, and the water bath dish is communicated with the first distillation bottle. With the present invention, the seamless connection between two distillation operations can be realized, the intermediate links can be reduced, the operation steps can be simplified, and the operation time can be shortened, thereby greatly improving work efficiency and reducing work intensity, and the distillation products during use and the cooling after heat exchange The thermal energy of water has been utilized, which improves the comprehensive utilization rate of materials and energy.

Description

technical field [0001] The present invention relates to a kind of laboratory equipment, more specifically, it relates to a kind of laboratory secondary distilled water device. Background technique [0002] Secondary distilled water with low conductivity is often used in analysis and measurement laboratories. The existing method for preparing double distilled water is generally to carry out the first distillation and receive it through a distillation device, and then pass the received primary distilled water through distillation. The device performs the second distillation to achieve the purpose of the second distillation. Using this method to perform the same operation twice is inefficient, time-consuming and laborious, and sometimes seriously affects the completion of the experimental task. In addition, there is a relatively high material consumption and energy consumption. The problem. The utility model with the publication number CN202849106U disclosed a double distilled...
