DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easily understood, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4 Shown in the figure, a low-temperature concentration device for Chinese herbal medicine extract includes a concentration outer shell 1, a vacuum pump 4, a liquid storage tank 5, a condensation device 6 and a connecting pipe 7. The vacuum pump 4 is connected to the inner wall of the concentration outer shell 1 through a pipe. One end of the connecting pipe 7 is fixedly connected to the upper surface of the concentration outer shell 1, and the other end of the connecting pipe 7 is fixedly connected to a condensation device 6. The outer surface of the condensation device 6 is connected to a liquid storage tank 5 through a pipe. The lower surface of the concentration outer shell 1 is fixedly connected to a motor 205, and the output shaft of the motor 205 passes through the inner wall of the concentration outer shell 1 and is fixedly connected to a cleaning frame 204. Among them, a three-way valve 301 is connected to the lower end of the concentration outer shell 1. One end of the three-way valve 301 is fixedly connected to a water pump 302, and the other end of the three-way valve 301 is fixedly connected to a discharge pipe 303.

[0024] In order to facilitate increasing the evaporation speed of the extract, the water outlet of the water pump 302 is fixedly connected to a circulation pipe 304, and the other end of the circulation pipe 304 is fixedly connected to the inner wall of the concentration outer shell 1. By starting the three-way valve 301 and the water pump 302, the extract in the concentration outer shell 1 can be pumped from the bottom of the concentration outer shell 1 to the top of the concentration outer shell 1. A fixing rod 306 is fixedly connected to the inner wall of the concentration outer shell 1, and a fixing plate 305 is fixedly connected to the lower surface of the fixing rod 306. The fixing rod 306 facilitates supporting the fixing plate 305. There is a gap between the outer surface of the fixing plate 305 and the inner wall of the concentration outer shell 1, and the center of the fixing plate 305 protrudes upward. Through the fixing plate 305, the extract at the top can flow evenly to the inner wall of the concentration outer shell 1, thereby accelerating the evaporation speed of the extract.

[0025] It is worth mentioning that by starting the three-way valve 301 and the water pump 302, the extract at the bottom of the concentration outer shell 1 is pumped into the top of the concentration outer shell 1 through the circulation pipe 304, so that the extract drops on the upper surface of the fixing plate 305, and the extract diffuses to the edge of the fixing plate 305, so that the extract flows to the inner wall of the concentration outer shell 1, which accelerates the evaporation speed of the extract to a certain extent.

[0026] To facilitate the cleaning of the concentration housing 1, the outer surface of the cleaning frame 204 is slidably connected to the inner wall of the concentration housing 1, and a heating housing 203 is fixedly connected to the outer surface of the concentration housing 1. A cavity 202 is formed between the inner side surface of the heating housing 203 and the outer surface of the concentration housing 1. The inner wall of the cavity 202 is filled with mineral oil. Through the mineral oil, the outer surfaces of the concentration housing 1 and the heating housing 203 that coincide can be heated evenly. Multiple groups of heating resistance wires 201 are embedded in the heating housing 203. The heating resistance wires 201 are arranged at intervals on the inner wall of the heating housing 203. Through the multiple groups of heating resistance wires 201, it is convenient to heat the concentration housing 1, and thus it is convenient to evaporate the extraction liquid in the concentration housing 1.

[0027] It is worth mentioning that when the motor 205 is started, the output shaft of the motor 205 drives the cleaning frame 204 to rotate. The rotation of the cleaning frame 204 is convenient for stirring the extraction liquid in the concentration housing 1, so that the extraction liquid can be heated evenly. On the other hand, the cleaning frame 204 rubs against the inner wall of the concentration housing 1, which is convenient for preventing the concentrated liquid medicine from adhering to the inner wall of the concentration housing 1 and causing the situation of bottom burning.

[0028] Working principle: By starting the three-way valve 301, the discharge pipeline 303 and the water pump 302 are connected. Then the discharge pipeline 303 is inserted into the extraction liquid, and starting the water pump 302 is convenient for pumping the extraction liquid into the concentration housing 1. Then the three-way valve 301 is closed, and the vacuum pump 4 is started. The vacuum pump 4 evacuates the concentration housing 1 into a vacuum state, which is convenient for reducing the boiling point of the extraction liquid and facilitating low-temperature concentration. Then the heating resistance wires 201 are started. The heating resistance wires 201 heat the mineral oil in the cavity 202. Through heat transfer, the heat is evenly transferred to the inner wall of the concentration housing 1, which is convenient for heating the extraction liquid evenly. Then the three-way valve 301 and the water pump 302 are started, so that the extraction liquid at the bottom of the concentration housing 1 is pumped to the top of the concentration housing 1 through the circulation pipeline 304, and the extraction liquid falls on the upper surface of the fixed disk 305. The extraction liquid diffuses towards the edge of the fixed disk 305, and the extraction liquid flows towards the inner wall of the concentration housing 1, which speeds up the evaporation speed of the extraction liquid to a certain extent. Then the motor 205 is started, and the output shaft of the motor 205 drives the cleaning frame 204 to rotate. The rotation of the cleaning frame 204 is convenient for stirring the extraction liquid in the concentration housing 1, so that the extraction liquid can be heated evenly. On the other hand, the cleaning frame 204 rubs against the inner wall of the concentration housing 1, which is convenient for preventing the concentrated liquid medicine from adhering to the inner wall of the concentration housing 1 and causing the situation of bottom burning. The evaporated extraction liquid is transmitted to the condensation device 6 through the connection pipeline 7 for condensation, and the condensed liquid is stored in the liquid storage tank 5.
