Chinese medicine is a traditional Chinese medicinal material. Chinese medicine culture has a long history and is profound and extensive. It is an important part of China's excellent culture. In order to ensure the normal use of medicinal materials in medicine, the medicinal materials are usually processed after picking. Drying is a kind of heating processing. In the processing of medicinal materials, the cleaned medicinal materials need to be dried. The medicinal material drying drum is a commonly used equipment for drying medicinal materials.
[0003] The drying drum dries the medicinal materials in the drum by heating and turning. In order to achieve evaporation and drying of water, a constant high temperature environment must be maintained inside the drying drum, and the evaporated water vapor is dissipated to the outside of the equipment through air circulation. Due to the lack of effective thermal insulation structure on the outside of the drying drum, a large amount of heat will be dissipated to the outside of the equipment when the drying drum is working, which is not only not conducive to the drying operation but also increases the working energy consumption of the equipment.

[0024] Example
[0025] See also Figure 1-5 The utility model provides a technical solution: a heat preservation structure for a granular medicinal material drying drum, comprising a heat preservation mechanism installed on the outside of a drying drum body 1, the drying drum body 1 can be made of stainless steel, and in order to facilitate the rotational drive of the drying drum body 1, a driving shaft 10 is arranged on one side of the drying drum body 1, and the driving shaft 10 is fixedly connected to the center of the end side of the drying drum body 1, and the end of the driving shaft 10 is connected to the shaft end of the motor, and the drying drum body 1 is rotatably installed in the interior of the heat preservation drum sleeve 2 through the driving shaft 10. In order to facilitate the input of medicinal material raw materials, as shown in the attached Figure 2 As shown, a feeding port 12 is provided on the other side of the drying cylinder 1. The feeding port 12 is opened at the center of the end side of the drying cylinder 1. The medicinal materials can be put into the drying cylinder 1 through the feeding port 12. In order to facilitate the flow of water and the discharge of steam, as shown in the attached Figure 2As shown, water filtering holes 11 are evenly arranged on the outer peripheral side of the drying cylinder 1.
[0026] The heat preservation mechanism includes a heat preservation sleeve 2, as shown in the attached Figure 2 As shown, the insulation sleeve 2 is in the shape of a sleeve, and the insulation sleeve 2 can be made of insulating ceramic material. The insulation sleeve 2 is installed in the shape of a sleeve on the outside of the drying cylinder 1. The shielding and isolation of the insulation sleeve 2 can effectively improve the circumferential insulation effect of the drying cylinder 1, which is beneficial to the improvement of the medicinal material drying effect and the energy-saving characteristics of the device. In order to heat the drying cylinder 1, a heater 3 is installed on the inner circumferential side of the insulation sleeve 2. The heater 3 can be a PTC heater. In order to facilitate the connection and installation of the heater 3, the inner circumferential side of the insulation sleeve 2 is evenly provided with installation grooves, and the heater 3 is fixedly installed inside the installation grooves.
[0027] In order to facilitate the discharge of steam, a steam exhaust port 8 and an exhaust slot 9 are provided on the inner side of the heat preservation sleeve 2. Figure 3 As shown, the steam exhaust port 8 is arranged on the upper inner circumference side of the insulation cylinder sleeve 2, and there are multiple steam exhaust ports 8. Several steam exhaust ports 8 are equidistantly opened on the inner circumference side of the insulation cylinder sleeve 2 in a horizontal row, and exhaust slots 9 are opened horizontally inside the insulation cylinder sleeve 2. The number of exhaust slots 9 corresponds to the number of rows of steam exhaust ports 8. The steam exhaust port 8 is communicated with the exhaust slots 9. The steam exhaust port 8 is utilized to dissipate and communicate the high-temperature steam generated in the drying cylinder body 1, and the steam is guided to circulate by arranging the exhaust slots 9. The exhaust slots 9 are uniformly arranged horizontally inside the insulation cylinder sleeve 2, so that the steam can circulate horizontally inside the insulation cylinder sleeve 2 when the steam circulates. By increasing the circulation stroke, the heat carried in the steam can be recycled for a second time, which can further improve the insulation effect of the insulation cylinder sleeve 2. One side of the exhaust slot 9 passes through one end side of the insulation cylinder sleeve 2 and is communicated with the external suction and exhaust equipment, so that the generated steam can be quickly discharged to the outside of the equipment.
[0028] In order to facilitate the discharge of dripping water, a water receiving trough seat 4 is arranged at the lower part of the insulation cylinder sleeve 2, and the water receiving trough seat 4 is fixed to the middle part of the bottom side of the insulation cylinder sleeve 2, so as to collect the water dripping in the drying cylinder body 1. In order to facilitate the flow of water, water leakage grooves 6 are evenly arranged on the upper side of the water receiving trough seat 4, and a water collecting cavity 5 is arranged inside the water receiving trough seat 4, and the water leakage groove 6 is connected with the water collecting cavity 5. In order to facilitate the discharge of water, a drainage interface 7 is arranged at the bottom of the water receiving trough seat 4, and the drainage interface 7 is connected with the water collecting cavity 5.
[0029] Working principle or structural principle, when working, the drying cylinder 1 rotates at a uniform speed driven by the external driving structure, and the medicinal materials in the drying cylinder 1 are turned over. When turning over, the water in the medicinal materials falls through the water filtering hole 11 and flows into the interior of the insulation cylinder sleeve 2. The water gathers on the inner bottom side of the insulation cylinder sleeve 2 and enters the water receiving tank seat 4 from the water leakage groove 6, and then is discharged from the drainage interface 7 at the bottom of the water receiving tank seat 4. At the same time, the heater 3 arranged on the inner peripheral side of the insulation cylinder sleeve 2 works to heat the medicinal materials in the drying cylinder 1. During the process, the insulation cylinder sleeve 2 is shielded and isolated on the peripheral side of the drying cylinder 1 to avoid a large amount of temperature loss, effectively improving the thermal insulation effect of the peripheral side of the drying cylinder 1. The water in the medicinal materials evaporates and volatilizes through the high temperature and the rotation of the drying cylinder 1, and then the steam enters the exhaust slot 9 through the steam exhaust port 8. The steam that enters moves and circulates along the exhaust slot 9 and is finally discharged to the outside, completing the drying process of the medicinal materials.
[0030] In summary, the thermal insulation structure adopts a cylinder seat type structure setting, which is installed in the shape of a cylinder sleeve on the outside of the drying cylinder 1. The shielding and isolation of the thermal insulation cylinder sleeve 2 can effectively improve the thermal insulation effect of the surrounding side of the drying cylinder 1, which is beneficial to the improvement of the medicinal material drying effect and the energy-saving characteristics of the device, and a steam exhaust port 8 and an exhaust slot 9 are arranged on the inner side of the thermal insulation cylinder sleeve 2. The steam exhaust port 8 is used to dissipate and connect the high-temperature steam generated in the drying cylinder 1, and the steam is guided to circulate by setting the exhaust slot 9. The exhaust slot 9 is evenly arranged laterally inside the thermal insulation cylinder sleeve 2, so that the steam can circulate laterally inside the thermal insulation cylinder sleeve 2 when the steam circulates. By increasing the circulation stroke, the heat carried in the steam can be recycled for a second time, which can further improve the thermal insulation effect of the thermal insulation cylinder sleeve 2.
