Description

Technical Field

[0001] This utility model relates to a grading and drying device for Chinese medicinal materials, belonging to the field of Chinese medicinal material processing technology. Background Technology

[0002] The shape and size of Chinese medicinal herbs all affect the drying process. To ensure the quality and medicinal properties of the herbs during drying, they need to be graded. Graded herbs can be heated and dried more evenly, thus avoiding quality problems caused by uneven heating.

[0003] Currently, the grading and drying of Chinese medicinal herbs requires at least two systems. First, the grading system is used to classify the herbs, and then the graded herbs are transferred to the drying system for drying. The overall structure is costly and energy-intensive, increasing the processing cost of Chinese medicinal herbs. Furthermore, the grading and drying process requires the transfer of herbs, which is inconvenient.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a Chinese medicinal herb grading and drying device that integrates the grading and drying functions of Chinese medicinal herbs. It is easy to operate, can avoid quality problems caused by uneven heating of medicinal herbs, and can also reduce the processing cost of Chinese medicinal herbs.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] The Chinese medicinal herb grading and drying device includes a vertical drying cylinder with a top cover; a horizontally arranged support frame is installed at the bottom of the inner cavity of the drying cylinder, and multiple sieve cylinders are stacked longitudinally above the support frame; a vertically arranged rotating shaft is installed at the bottom of the inner cavity of each sieve cylinder, and the rotating shafts in adjacent sieve cylinders are connected by splines, with the rotating shaft in the bottommost sieve cylinder connected to a motor by a spline; multiple spiral heating tubes are installed longitudinally on the inner wall of the drying cylinder, and the temperature of the multiple spiral heating tubes decreases sequentially from top to bottom.

[0008] Furthermore, except for the bottommost sieve cylinder, the bottom of the other sieve cylinders is provided with sieve holes, and the mesh size of the sieve holes increases sequentially from top to bottom.

[0009] Furthermore, the rotating shaft is connected to the bottom of the screen cylinder via a bearing housing.

[0010] Furthermore, the upper part of the main body of the rotating shaft is located inside the screen cylinder, and multiple blades distributed in a circular pattern are installed on the upper part of the main body, while the lower part of the main body of the rotating shaft is located below the screen cylinder.

[0011] Furthermore, the spiral heating tubes are located on the periphery of the sieve cylinder, and the temperatures of the multiple spiral heating tubes are different.

[0012] Furthermore, adjacent screen cylinders are connected by a snap-fit ​​mechanism, and the top of each screen cylinder is open with an inner chamfer inside the opening. The bottom of each screen cylinder has an outer chamfer on its outer perimeter, and the inner and outer chamfers of adjacent screen cylinders are matched.

[0013] Furthermore, the top cover is hinged on the side and can be flipped outwards.

[0014] Furthermore, the top cover is equipped with a feed inlet and a moisture outlet.

[0015] Furthermore, the feed inlet adopts a structure that is larger at the top and smaller at the bottom, while the moisture outlet adopts a structure that is larger at the bottom and smaller at the top.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] In this invention, a motor drives multiple rotating shafts at the top to rotate synchronously, which in turn drives the corresponding blades inside the sieve cylinder to rotate. Under the action of the blades, the Chinese medicinal materials are graded according to their size. The largest Chinese medicinal materials remain in the top sieve cylinder, and the smallest Chinese medicinal materials enter the bottom sieve cylinder. After grading, the spiral heating tubes around the sieve cylinder are energized and heated. The temperature of the multiple spiral heating tubes decreases sequentially from top to bottom. The spiral heating tubes at different temperatures dry the Chinese medicinal materials of different volumes, which can ensure effective drying of large-volume Chinese medicinal materials and avoid over-drying of small-volume Chinese medicinal materials.

[0018] This utility model integrates the grading and drying functions of Chinese medicinal materials, making it easy to operate. It can not only avoid quality problems caused by uneven heating of medicinal materials, but also reduce the processing cost of Chinese medicinal materials.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the structure of this utility model;

[0021] Figure 2 This is a schematic diagram of the internal structure of the sieve cylinder.

[0022] In the diagram, 1-drying cylinder, 2-top cover, 3-screen cylinder, 31-inner chamfer, 32-outer chamfer, 4-rotating shaft, 5-bearing seat, 6-blade, 7-motor, 8-support frame, 9-spiral heating tube, 10-feed inlet, 11-moisture outlet. Detailed Implementation

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a Chinese herbal medicine grading and drying device, including a vertical drying cylinder 1, the top of the drying cylinder 1 is provided with an open end, a top cover 2 is installed at the open end, the side of the top cover 2 is hinged and can be flipped outward.

[0025] A horizontally arranged support frame 8 is installed at the bottom of the inner cavity of the drying cylinder 1. Above the support frame 8, multiple sieve cylinders 3 are stacked longitudinally. Except for the bottommost sieve cylinder 3, the bottom of the other sieve cylinders 3 are provided with sieve holes, and the mesh size of the sieve holes increases from top to bottom.

[0026] Adjacent screen cylinders 3 are connected by a snap-fit ​​mechanism. The top of each screen cylinder 3 is open, and an inner chamfer 31 is provided inside the opening. An outer chamfer 32 is provided on the outer periphery of the bottom of the screen cylinder 3. The inner chamfer 31 and the outer chamfer 32 of adjacent screen cylinders 3 cooperate to achieve a tight snap-fit ​​connection.

[0027] The bottom of the inner cavity of the screen cylinder 3 is equipped with a rotating shaft 4 arranged in a vertical direction. The rotating shaft 4 is connected to the bottom of the screen cylinder 3 through a bearing seat 5. The upper part of the main body of the rotating shaft 4 is located inside the screen cylinder 3, and multiple blades 6 are installed on the upper part of the main body in a circular arrangement. The lower part of the main body of the rotating shaft 4 is located below the screen cylinder 3.

[0028] The rotating shafts 4 inside adjacent screen cylinders 3 are connected by splines, and the rotating shaft 4 inside the bottom screen cylinder 3 is connected to the motor 7 by splines. The motor 7 drives the multiple rotating shafts 4 above to rotate synchronously, which in turn drives the corresponding blades 6 to rotate. The blades 6 stir the material, which can not only assist in screening, but also make the material heat up evenly.

[0029] Multiple spiral heating tubes 9 are installed longitudinally on the inner wall of the drying cylinder 1. The spiral heating tubes 9 are located on the periphery of the screen cylinder 3. The temperatures of the multiple spiral heating tubes 9 are different, and the temperatures decrease sequentially from top to bottom. The spiral heating tubes 9 at different temperatures are used to dry materials of different volumes.

[0030] During the fastening process, the top cover 2 can press multiple screen cylinders 3 into the inner cavity of the drying cylinder 1. The top cover 2 is provided with a feed inlet 10 and a moisture outlet 11. The feed inlet 10 adopts a structure that is larger at the top and smaller at the bottom to facilitate the input of materials. The moisture outlet 11 adopts a structure that is larger at the bottom and smaller at the top to facilitate the concentrated output of moisture after it is collected.

[0031] The specific working principle of this utility model is as follows:

[0032] The Chinese medicinal materials are fed into the uppermost sieve cylinder 3 through the feed inlet 10, and then the top cover 2 is closed, pressing the multiple sieve cylinders 3 tightly into the inner cavity of the drying cylinder 1. Then, the motor 7 drives the multiple rotating shafts 4 above to rotate synchronously, thereby driving the corresponding blades 6 inside the sieve cylinder 3 to rotate. Under the action of the blades 6, the Chinese medicinal materials are graded according to their volume. The largest Chinese medicinal materials stay in the top sieve cylinder 3, and the smallest Chinese medicinal materials enter the bottom sieve cylinder 3. After grading, the spiral heating tubes 9 around the sieve cylinder 3 are energized and heated. The temperature of the multiple spiral heating tubes 9 decreases from top to bottom. The spiral heating tubes 9 at different temperatures dry the Chinese medicinal materials of different volumes, which can ensure the effective drying of large-volume Chinese medicinal materials and avoid the problem of over-drying of small-volume Chinese medicinal materials. After drying, each sieve cylinder 3 can be removed individually for discharge.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
