[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0023] Please refer to the attached Figure 1-Figure 4 As shown, the utility model provides a technical solution: a negative pressure distillation kettle condensation reflux structure, including a support platform 10, four support columns 13 are fixedly installed at the four corners of the lower end of the support platform 10, respectively, to facilitate supporting the support platform 10, two support plates 11 are fixedly installed on the support platform 10, and a support box 12 is fixedly installed on the two support plates 11, and a transition chamber 121 and a condensation chamber 122 are provided in the support box 12, and a kettle body 20 is installed at one end of the two support plates 11 of the support platform 10, and a liquid inlet 21 and an air outlet pipe 22 are fixedly installed on the upper end of the kettle body 20, one end of the air outlet pipe 22 is arranged through the transition chamber 121 and the condensation chamber 122, and one end of the air outlet pipe 22 is fixedly connected to the outer surface of the lower end of the kettle body 20.

[0024] In this embodiment, the outlet pipe 22 is arranged at the upper and lower ends of the transition chamber 121 and the condensation chamber 122. The upper end of the outlet pipe 22 in the condensation chamber 122 is provided with a corrugated section 221, so that the time of the gas in the outlet pipe 22 in the condensation chamber 122 is increased, so that the gas is completely condensed into liquid. The lower end of the outlet pipe 22 in the transition chamber 121 is provided with a raised section 222, which is convenient for heating the condensed liquid. The part of the outlet pipe 22 between the kettle body 20 and the support box 12 is inclined downward, so that the condensed liquid can quickly enter the kettle body 20.

[0025] In this embodiment, the transition chamber 121 is filled with a normal temperature aqueous solution, and the condensation chamber 122 is filled with a cooling liquid. The normal temperature aqueous solution is used to cool the gas flowing out of the kettle body 10 and to heat the condensed liquid.

[0026] Specifically, the gas in the kettle body 20 enters the transition chamber 121 through the gas outlet pipe 22, so that the temperature of the aqueous solution in the transition chamber 121 is higher than normal temperature. The gas passes through the corrugated section 221 in the condensation chamber 122 and condenses into liquid. It passes through the raised section 222 in the transition chamber 121 again, so that the condensed liquid passes through the aqueous solution to heat up the temperature, and then enters the kettle body 10, so that the temperature fluctuation in the distillation kettle will not be too large, thereby affecting the distillation speed.

[0027] In this embodiment, the lower end of the support platform 10 is fixedly connected to a fixed box 30 just below the kettle body 20, and a first liquid outlet pipe 23 is fixedly installed on the lower end of the kettle body 20 and one side of the fixed box 30. A first valve 24 is installed on the first liquid outlet pipe 23 to facilitate controlling the liquid in the kettle body 10 to enter the fixed box 30. The lower end of the fixed box 30 is fixedly connected to a second liquid outlet pipe 34, and a second valve 35 is installed on the second liquid outlet pipe 34 to facilitate controlling the outflow of filtered liquid.

[0028] In this embodiment, one end of the fixed box 30 is open, and two L-shaped connecting rods 301 are fixedly connected at both ends of one side of the opening of the fixed box 30, a slide plate 31 is slidably installed on the fixed box 30 and the two L-shaped connecting rods 301, and a filter screen 32 is slidably installed on the slide plate 31. The first liquid outlet pipe 23 is connected to one end of the fixed box 30 and is arranged at the upper end of the filter screen 32, so that the impurities that are too large in the liquid in the kettle body 20 are filtered out through the filter screen 32.

[0029] In this embodiment, two fixed blocks 302 are fixedly connected to both sides of the lower end of the fixed box 30, and the lower end of the slide plate 31 extends to the lower ends of the two L-shaped connecting rods 301. Two springs 33 are fixedly installed on one side of the two fixed blocks 302 and the extended part of the slide plate 31, so that the slide plate 31 can be restored to its original position after the slide plate 31 is pulled and the filter screen 32 in the slide plate 31 is replaced.

[0030] In this embodiment, a groove 303 is formed at the lower end of the inner wall of the fixed box 30 to prevent the filtered liquid from remaining in the fixed box 30 when the second valve 35 is controlled to collect the liquid in the fixed box 30 .

[0031] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
