DETAILED DESCRIPTION

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] Example 1

[0027] like Figures 1-4 As shown, a high-efficiency traditional Chinese medicine distillation extraction tank includes a tank body 1, a feeding assembly 2 and an air extraction assembly 3 located on the upper part of the tank body, and a filter assembly 4 located inside the tank body. A heating assembly 5 is located below the filter assembly. The heating assembly 5 includes an inner cylinder (51), an outer cylinder 52, an upper connecting plate 53 for connecting the upper end of the inner cylinder 51 and the upper end of the outer cylinder 52, a lower connecting plate 54 for connecting the lower ends of the inner cylinder 51 and the outer cylinder 52, and multiple heat exchange tubes 55 for connecting the upper connecting plate 53 and the lower connecting plate 54. The distance between the upper end of the heat exchange tube 55 and the axis of the inner cylinder 51 is greater than the distance between the lower end and the axis of the inner cylinder 51. A heat exchange cavity 56 is formed between the inner cylinder 51, the outer cylinder 52, the upper connecting plate 53, and the lower connecting plate 54. The heat exchange chamber 56 is provided with a heating steam inlet 57 and a condensate outlet 58. The distance between the upper end of the heat exchange tube 55 and the axis of the inner cylinder 51 is greater than the distance between the lower end and the axis of the inner cylinder 51. The bottom of the tank 1 is provided with a lower cover plate 6. The lower cover plate 6 is provided with a cleaning assembly 7. The cleaning assembly 7 includes a cleaning liquid delivery pipe 71. The cleaning liquid delivery pipe 71 passes through the inner cylinder 51 and is provided with cleaning nozzles 72 at both the upper and lower ends. The bottom of the tank 1 is also provided with a connecting pipe 8 for observing the liquid level inside the tank 1. One end of the connecting pipe 8 passes through the lower cover plate 6 and communicates with the inside of the tank 1. The other end is located outside the tank 1 and extends to the side of the tank 1. The tank 1 is also provided with a level gauge 10.

[0028] In use of the distillation extraction tank, water is injected into the tank body 1 to make the liquid level below the filter assembly 4, the liquid fills the heat exchange pipe 55, and then the medicine to be extracted is placed above the filter assembly 4. When heated, the heating medium enters the heat exchange cavity 56 from the heating steam inlet 57. Since the heating assembly 5 is composed of the heating pipe bundle and the heat exchange pipe 55 is parallel to the inner cylinder body 51, when the heating medium enters the heat exchange cavity 56, the heating pipe 55 has a large heating area per unit volume of liquid, which can generate a large amount of steam towards the top of the tank body 1, so that the steam covers the entire cross section of the tank body 1, thereby achieving effective extraction of the medicine. Compared with straight-through steam cooking, the steam is more widely distributed and has a smaller flow rate, effectively avoiding the phenomena of deflection and channeling of steam in the tank body 1 during cooking caused by excessive concentration of straight-through steam, greatly improving the distillation effect and ensuring the quality of the distillate. The air extraction assembly 3 performs vacuum extraction to collect the medicine extract. The communication pipe 8 connected to the tank body 1 cooperates with the liquid level meter 10 to control the liquid level in the tank body 1, avoiding the problem of inaccurate liquid level measurement caused by severe fluctuation of the liquid level in the tank body 1 during cooking, and ensuring the control accuracy and stability of the steam.

[0029] Specifically, the communication pipe 8 is a high-temperature-resistant transparent glass pipe or a high-temperature-resistant transparent plastic pipe.

[0030] Further, the upper side of the heating assembly 5 (between the heating assembly 5 and the filter assembly 4) is also provided with a steam-water separation device 9, which can effectively prevent the water vapor carrying effective components from flowing to the heating assembly and causing loss of effective components.

[0031] Specifically, as shown in Figure 5 and Figure 6 , the steam-water separation device 9 includes a first separation plate 91 and a second separation plate 92 arranged on the first separation plate 91, and the second separation plate 92 has a conical structure. More specifically, the first separation plate 91 is a porous mesh plate structure, and the second separation plate 92 has a double-layer structure, with the outer layer being a filter screen structure and the inner layer being a filter plate structure.

[0032] Specifically, as shown in Figure 4 , the cleaning nozzle 72 is connected to the cleaning liquid delivery pipe 71 through a cleaning pipe 73, and a check valve 74 is arranged on the cleaning pipe 73, which is located between the cleaning nozzle 72 and the cleaning liquid delivery pipe 71. Further, a plurality of cleaning nozzles 72 are arranged on the upper and lower ends of the cleaning liquid delivery pipe 71.

[0033] As a preferred embodiment, the included angle α between the heat exchange pipe 55 and the lower connecting plate 54 is 0 < α ≤ 75°, which ensures the heating effect of the heating assembly 5.

[0034] In this embodiment, the filter assembly 4 is a filter plate with waist-shaped filter holes and an upwardly convex arc structure, so that steam can pass through the filter assembly better and fill the tank 1.

[0035] More specifically, such as Figure 7 As shown, the feeding assembly 2 includes a feeding cylinder 21 and a feeding cylinder 22. The feeding cylinder 21 is connected to the tank body 1 through the feeding cylinder 22. The axis of the feeding cylinder 21 is parallel to the axis of the tank body 1, and the axis of the feeding cylinder 22 intersects the axis of the tank body 1. The air extraction assembly 3 includes an air extraction pipe 31 and an air extraction device 32. The air extraction device 32 is connected to the tank body 1 through the air extraction pipe 31.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and not to limit it; although the implementation of this utility model has been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model, and such modifications and variations all fall within the scope defined by the appended claims.
