Description

Technical Field

[0001] The utility model relates to the field of medicinal material processing equipment, in particular to a drying device used for medicinal material extraction. Background Art

[0002] Medicinal materials are raw materials for making medicines, and in China, they especially refer to Chinese medicinal materials, that is, raw materials for Chinese medicine that have not been processed or made into finished products. Chinese medicine is a traditional Chinese medicinal material. Chinese medicine culture has a long history and is profound and extensive. It not only includes thousands of years of Chinese medicine civilization but also integrates the unique cultural phenomenon of Chinese and Western medicine created by modern Western medicine civilization. It is an important part of China's excellent culture.

[0003] Currently, medicinal materials need to be dried before use to remove a large amount of moisture inside the medicinal materials and facilitate the extraction of the medicinal materials. The existing method is to dry them naturally in the sun, which is cumbersome to operate and easily affected by the weather, resulting in low drying efficiency. In order to improve the drying efficiency, some factories use drying boxes to dry the medicinal materials with hot air. This method is to place the medicinal materials in layers in a flat manner in the drying box, which is convenient for drying multiple medicinal materials at one time. However, since the hot air in the existing drying box usually enters the interior from any position during drying, it is bound to cause the medicinal materials near the air inlet to dry faster than the medicinal materials far from the air inlet, thereby resulting in uneven drying. Utility Model Content

[0004] Therefore, in order to solve at least one of the above-mentioned shortcomings, the present invention provides a drying device for medicinal material extraction. The drying device can facilitate the layered placement of medicinal materials through the placement plates, air supply boxes and induced draft fans placed in layers in the drying box, and facilitate the medicinal materials to be spread flat in the drying box for drying. At the same time, the air supply trough plates arranged in the drying box and kept in communication with the placement plates respectively facilitate the uniform discharge of the positive pressure air of the air supply box to the position of each layer of the placement plates, thereby ensuring the uniformity of the drying of the medicinal materials.

A plurality of support portions and ventilation portions linearly distributed along the height direction of the drying box are provided on the opposite surfaces of the two air supply trough plates, and the plurality of support portions and ventilation portions are staggered. The placement plate is placed on the support portions of the two air supply trough plates, and the ventilation portions are ventilation holes, which connect the inner ends of the air supply trough plates with the interior of the drying box. Air guide portions are respectively provided at positions corresponding to each ventilation portion at the inner ends of the air supply trough plates. The air guide portions are arranged obliquely upward and the lowest end is kept on the side of the inner end of the air supply trough plate away from the ventilation portion, and there is a gap between the highest end and the ventilation portion.

[0012] Specifically, the sizes of the plurality of air guide portions vary with the positions of the air supply slot plates, and the air guide portions close to the air supply box are smaller than the air guide portions far from the air supply box.

[0030] As described in the background art, existing medicinal material drying equipment easily causes uneven drying because the medicinal materials are placed in layers for drying.

[0031] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 6 , the utility model provides a drying device for extracting medicinal materials, comprising a drying box 1, which is provided with a plurality of layered placement plates 7;

[0032] The air supply box 2 is arranged at the bottom of the drying box 1 and is provided with an induced draft fan 3 at the outer end for conveying positive pressure air into the air supply box;

[0033] The air supply trough plates 6 are arranged on both sides of the drying box 1 and keep one end connected with the air supply box 2, and the other end keeps connected with each layer of the placement plate 7.

[0034] Specifically, the side of the drying box 1 is provided with an opening, a door 4 is hinged at the end of the opening, and an exhaust pipe 5 is provided on the top of the drying box 1.

[0035] In order to achieve communication between the air supply box and the drying box through the air supply trough plate, thereby ensuring the uniformity of air supply, a feasible technical solution is provided herein. Specifically, a baffle 8 is provided at the inner bottom of the drying box 1, and the baffle 8 is provided between the air supply trough plates 6. A water collecting trough is provided on the top of the baffle 8, and a drainage pipe 9 is provided on the side of the drying box 1 that is connected to the lowest point of the water collecting trough.

[0036] The drainage groove and drainage pipe on the top of the baffle are provided to facilitate the discharge of water stains flowing out of the medicinal material container when it is drained.

[0037] In order to improve the efficiency of drying medicinal materials, a feasible technical solution is proposed herein. Specifically, an electric heating wire 10 is further provided inside the air supply box 2. The electric heating wire is an existing conventional heating wire structure, and the start-up and heating temperature can be controlled by an external circuit.

[0038] In order to achieve communication between the air supply box and the drying box through the air supply trough plate, thereby ensuring that air can be supplied upward from the bottom of each layer of placement plates, thereby drying the medicinal materials on the placement plates, a feasible technical solution is provided herein. Specifically, the cross-section of the air supply trough plate 6 is a rectangular frame shape, and its top remains closed. A plurality of support parts 6.1 and ventilation parts 6.2 are linearly distributed along the height direction of the drying box 1 on the opposite surfaces of the two air supply trough plates 6. The plurality of support parts 6.1 and ventilation parts 6.2 are staggered. The placement plate 7 is placed on the support parts 6.1 of the two air supply trough plates 6. The ventilation parts 6.2 are ventilation holes, which connect the inner ends of the air supply trough plates 6 with the interior of the drying box 1. At the positions corresponding to each ventilation part 6.2 at the inner ends of the air supply trough plates 6, air guide parts 6.3 are respectively provided. The air guide parts 6.3 are arranged obliquely upward and the lowest end is arranged on the side of the inner end of the air supply trough plate 6 away from the ventilation part 6.2. There is a gap between the highest end and the ventilation part 6.2. See the attached figure. Figure 7 It can be seen.

[0039] In order to solve the problem that after the hot air is transported upward and dried with the medicinal materials on the bottom plate, the temperature of the hot air above becomes lower due to energy loss or heat exchange, resulting in uneven drying, a feasible solution is provided herein. Specifically, the size of the multiple air guide parts 6.3 changes with the position of the air supply trough plate 6, and the air guide part 6.3 close to the air supply box 2 is smaller than the size of the air guide part 6.3 away from the air supply box 2.

[0040] Specifically, ventilation holes are provided on the air guide portion 6.3. The purpose of this arrangement is to facilitate the flow of air in the air supply trough plate and reduce the noise generated during air supply.

[0041] Specifically, ventilation holes are evenly provided on the placement plate 7. The purpose of this arrangement is to facilitate the drying of the medicinal materials on the placement plate and to facilitate the internal air flow.

[0042] When the drying device is in use, the induced draft fan 3 and the electric heating wire 10 are connected to the external circuit in advance, and then the box door 4 is opened to lay the medicinal materials flat on the placement plate 7. After placement, the box door 4 is closed, and the induced draft fan 3 and the electric heating wire 10 are started. The induced draft fan 3 pressurizes the external air and transports it to the inside of the air supply box 2. After passing through the electric heating wire 10, the pressurized air is heated and enters the air supply trough plate 6 after being blocked by the baffle 8. Then, a small part of the heated air enters the drying box 1 from the ventilation part 6.2 at the corresponding position under the obstruction of the air guide part 6.3. Since the heated air flows upward and is blocked by the baffle 8 at the bottom, the heated air will flow upward through the through holes of the placement plate 7 and come into contact with the medicinal materials to achieve drying. The heated air after contacting the medicinal materials Due to heat exchange, the temperature of the air becomes lower and it continues to flow upward to contact the medicinal materials on the next placement plate 7, while the remaining heated air in the air supply trough plate 6 passes through the air guide part 6.3 and continues to flow upward. After reaching the position of the next air guide part 6.3, a small part of the heated air passes through the ventilation part 6.2 at the corresponding position and enters the drying box 1. While flowing upward, it merges with the air passing through the lower placement plate 7, thereby increasing the temperature of the air passing through the lower placement plate 7, and continuing to dry the medicinal materials on the upper placement plate 7, achieving uniform drying of the medicinal materials on the layered placement plates. The above steps are repeated until the air passes through the topmost placement plate 7 and is discharged from the exhaust pipe 5, thereby forming an air flow path for drying the medicinal materials. The medicinal materials can be dried continuously according to the above air flow path.

[0043] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
