Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an improved device for distilling Chinese medicinal slices to prevent clogging. Background Art

[0002] Distillation is a method that utilizes the volatility difference of each component in a system to partially vaporize it by heating, resulting in gas and liquid phases, thereby enriching the light component in the gas phase and the heavy component in the liquid phase to achieve separation. Distillation is a traditional Chinese medicine method for extracting Chinese medicine preparations. Through distillation, the medicinal components in Chinese medicinal materials that are easily soluble in water and easily volatilized with water distillation can be extracted and collected; however, there are many problems in the current medicinal material distillation process;

[0003] First, after the medicinal materials are poured into the distillation device, the medicinal materials are unevenly distributed, and the heating device heats the medicinal materials unevenly. Therefore, many types of stirring mechanisms are added to the existing distillation devices to promote the uniform distribution of the medicinal materials in the distillate. However, the sizes of the medicinal materials are different. Although simple stirring can promote the uniform distribution of the medicinal materials to a certain extent, since the stirring is only clockwise / counterclockwise stirring, it still cannot change the problem that the medicinal materials with large mass sink to the bottom, and the small mass of the broken slag-like medicinal materials float on the upper part of the distillation layer. The mass density of the upper and lower layers in the distillate is quite different, and the uniform heat transfer of the heating element is affected, resulting in the problem of slow heating of the distillate and low distillation efficiency.

[0004] Moreover, the floating broken slag medicinal materials stirred by the stirring mechanism are easy to enter the distillation pipeline, block the pipeline, affect the transmission, condensation and collection of the medicinal liquid vapor, and even cause high pressure dangerous events in the case of serious blockage;

[0005] In summary, the problems existing in the prior art of Chinese medicinal material distillation device are as follows:

[0006] 1. The stirring mechanism used in the prior art Chinese herbal medicine distillation device is mostly to simply stir the distillate containing the herbal medicine clockwise or counterclockwise. The herbal medicine with large mass sinks to the bottom, while the herbal medicine with small mass floats on the upper layer of the distillate. The mass density difference between the upper and lower layers of the distillate is large, which affects the uniform heat transfer of the heating element, resulting in slow heating of the distillate and low distillation efficiency.

[0007] 2. In the prior art Chinese medicinal material distillation device, the distillation tube is easily blocked by the floating medicinal materials, which affects the transmission, condensation and collection of the medicinal liquid vapor, and even causes a high pressure dangerous event in the case of severe blockage.

[0015] The stirring element is a cylinder, and cylinders with paddles are symmetrically arranged on both sides of the cylinder, and the paddles are spiral paddles;

[0016] The output shaft drives the paddle disc to rotate and reciprocate up and down, stirring the distillate and medicinal materials in the distillation barrel up and down, so that the medicinal materials that have settled on the bottom are distributed in the distillate as the stirring disc is stirred up and down. In the process of the stirring disc moving up and down, the stirring element is pushed by the resistance of the distillate to rotate, and the distillate and medicinal materials are further stirred by the paddle blades to ensure that the density at each position in the distillate is the same;

[0017] Furthermore, the filter element includes a skeleton; the skeleton is a hexagonal skeleton composed of six plates, a motor is arranged in the middle of the skeleton, and a filter cloth is sleeved on the outer wall of the skeleton; the width of the skeleton is consistent with the width of the installation slot, and the outermost end of the skeleton always contacts the wall of the installation slot; the motor is installed in the side wall of the installation slot; the filter cloth at the lower end of the filter element is kept horizontal; the keel is driven to rotate by the rotation of the motor, and the filter cloths on the six surfaces of the hexagonal keel are controlled to filter the distilled steam alternately, and during the alternation, the filter cloth with filter residue contacts the bristles to clean the filter cloth.

[0033] The lower end of the distillation barrel 1 is detachably connected to a stepper motor 8035, and a heating element 6 is arranged at the lower end of the distillation barrel 1; the output shaft of the stepper motor 8035 extends into the distillation barrel 1, and the output shaft is threadedly connected to a stirring plate 7; four fan-shaped holes are arranged in an array on the stirring plate 7, and a stirring element 701 is rotatably connected in the fan-shaped holes; the middle part of the stirring element 701 is a round rod, and cylinders with paddles are symmetrically arranged on both sides of the round rod;

[0034] The cylinder cover is provided with a distillation tube connected to the condensation barrel 3, a circular groove is provided on the cylinder cover at the lower part of the distillation tube to install the filter element 8, and bristles 2011 are symmetrically arranged in the circular groove to clean the drug residue on the filter cloth 802; the filter element 8 includes a frame 801, and the frame 801 is a hexagonal frame 801, and the filter cloth 802 is sleeved on the frame 801;

[0035] Specific usage:

[0036] The distillation liquid and medicinal materials are added into the distillation barrel 1 by opening and closing the barrel cover, and the distillation barrel 1 is closed. The heating element 6 and the stepper motor 8035 are controlled to work. The stepper motor 8035 drives the stirring plate 7 to rotate. The paddle plate rotates and reciprocates up and down, and the distillation liquid and the medicinal materials are stirred in a circular motion and up and down.
