[0031] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

The present application provides the following embodiments.

[0034] As shown in the structure schematic diagram of the vacuum distillation equipment in the embodiment, the vacuum distillation equipment in the embodiment extracts target products, and includes an evaporation assembly 100 and a condensation assembly 200. The material enters the evaporation assembly 100 and is heated and evaporated by a heater in the evaporation assembly 100, the evaporated material enters the condensation assembly 200 to be condensed into liquid and collected, thereby realizing distillation extraction work. Figures 1-3 As shown in the structure schematic diagram of the vacuum distillation equipment in the embodiment, the vacuum distillation equipment in the embodiment extracts target products, and includes an evaporation assembly 100 and a condensation assembly 200. The material enters the evaporation assembly 100 and is heated and evaporated by a heater in the evaporation assembly 100, the evaporated material enters the condensation assembly 200 to be condensed into liquid and collected, thereby realizing distillation extraction work.

[0035] Figures 1-3 As shown in the structure schematic diagram of the vacuum distillation equipment in the embodiment, the vacuum distillation equipment in the embodiment extracts target products, and includes an evaporation assembly 100 and a condensation assembly 200. The material enters the evaporation assembly 100 and is heated and evaporated by a heater in the evaporation assembly 100, the evaporated material enters the condensation assembly 200 to be condensed into liquid and collected, thereby realizing distillation extraction work.

[0036] It is worth noting that the tank 101 in the embodiment is also connected with a vacuum machine, which forms a negative pressure in the tank 101 by suction, avoiding the problem of reduction of material purity caused by reaction of gas with the material in the tank 101. ​

[0037] In addition, the bottom of the tank 101 in this embodiment is provided with a discharge port 103. After the distillation and extraction operation is completed, the material in the tank is discharged through the discharge port 103.

[0038] like Figures 4-6 As shown, in this embodiment, a condensation assembly 200 is installed on the top of the tank 101. The condensation assembly 200 includes a connecting pipe 201 and a cooling assembly 202 assembled with the connecting pipe 201. Additionally, the condensation assembly 200 includes a condenser 203, which is assembled to the end of the cooling assembly 202 via the connecting pipe 201. In this embodiment, the vapor of the target product undergoes preliminary cooling in the cooling assembly 202 and then enters the condenser 203 through the connecting pipe 201, where it condenses into a liquid for collection. In this embodiment, the target product vapor obtained after preliminary cooling by the cooling assembly 202 is condensed in the condenser 203. Because the vapor undergoes preliminary cooling, the condensation effect in the condenser 203 is better, avoiding the problem of incomplete condensation in the condenser 203 leading to a decrease in extraction rate.

[0039] like Figure 4 As shown, in this embodiment, the condenser 203 includes an outer shell 203a, and a spiral tube 203c is installed in the outer shell 203a.

In addition, a refrigerant inlet and a refrigerant outlet are provided on the outer shell 203a. After the evaporated steam is initially cooled, it enters the spiral tube 203c through the feed port 203b. The refrigerant enters the cavity between the outer shell 203a and the spiral tube 203c through the refrigerant inlet to condense the steam in the spiral tube. The refrigerant is discharged through the refrigerant outlet. After the steam condenses into liquid in the spiral tube 203c, it is discharged through the discharge port 203d for collection.

[0040] like Figure 7 as well as Figure 8As shown, it is the structural schematic diagram of one of the embodiments of the cooling assembly 202 in the embodiment, the cooling assembly 202 in the embodiment includes the expansion pipe 202a and the joints 202b at both ends of the expansion pipe 202a, in the embodiment, the expansion pipe 202a is installed on the connecting pipe 201 through the joints 202b at both ends, and the connecting pipe 201 communicates with the expansion pipe 202a, in the embodiment, the fixed plates 202c are oppositely arranged in the expansion pipe 202a, the guide pipes 202d are connected between the fixed plates 202c, and the guide pipes 202d communicate with the outside of the fixed plates 202c, in the embodiment, the steam of the target product enters the expansion pipe 202a through the connecting pipe 201 and then disperses into the guide pipes 202d, because the guide pipes 202d are annularly distributed on the fixed plates 202c and close to the inner wall of the expansion pipe 202a, the heat in the airflow can be easily exchanged with the air outside the expansion pipe 202a for preliminary cooling, thus avoiding the situation that the temperature of the overall flow center of the airflow in the connecting pipe 201 cannot be effectively cooled, therefore, in the embodiment, the expansion pipe 202a can make the airflow disperse and flow and efficiently exchange heat with the surrounding air, so that the steam can achieve the effect of preliminary cooling.

[0041] As shown in Figure 9 and Figure 10 As shown, it is the structural schematic diagram of another embodiment of the cooling assembly 202 in the embodiment, the cooling assembly 202 in the embodiment includes the symmetrically arranged buffer covers 202e, the buffer covers 202e are hollow inside and communicate with the connecting pipe 201, and the buffer covers 202e are connected through the communicating pipes 202f, in the embodiment, the steam enters the communicating pipes 202f after entering the buffer covers 202e through the connecting pipe 201, because the communicating pipes 202f contact with the air, the steam can quickly exchange heat with the air in the communicating pipes 202f to achieve the purpose of preliminary cooling.

[0042] In the embodiment, the steam of the target product is preliminarily cooled by the cooling assembly 202, so that the steam of the target product can be quickly condensed and formed into a liquid for collection when entering the condenser 203, which guarantees the condensation efficiency and improves the yield of extracting the target product, in addition, it should be noted that the cooling assembly 202 in the embodiment can be provided with multiple ones and be assembled on the connecting pipe 201 in sections, so as to improve the effect of preliminary cooling and guarantee the condensation efficiency.
