Description

Technical Field

[0001] This application relates to the technical field of traditional Chinese medicine preparation, and particularly to a traditional Chinese medicine calcining machine. Background Art

[0002] Traditional Chinese medicine is a traditional Chinese medicinal material, mainly composed of plant medicine and mineral medicine. Among them, mineral medicine is mainly processed and prepared through calcination and purification. Currently, a calcining machine is often used for calcination. The existing calcining machine mainly consists of a furnace body, a furnace door lifting device, an electric controller device, a trolley, a resistance wire, a thermocouple, and a heat preservation layer. The medicinal materials are sent into the furnace body by the trolley, and the electric control device is used to control the resistance wire to be energized and heated, so as to carry out high-temperature calcination on the medicinal materials in the furnace. After the medicinal materials are calcined, the heating can be stopped, and then the medicinal materials are manually taken out to complete the calcining work.

[0003] When the existing calcining machine is in use, the medicinal materials are centrally placed in the calcining furnace for high-temperature calcination. Since the heating resistance wire is arranged on the two side walls inside the furnace body, during high-temperature calcination, the temperature of the medicinal materials on both sides is higher than that of the medicinal materials in the middle, that is, the temperature inside and outside the medicinal materials is inconsistent, and the heating is uneven. Moreover, the accumulation of medicinal materials results in a slow heating efficiency, which will lead to the problems of undercooked or burnt medicinal materials, greatly reducing the quality of the medicinal materials, causing the medicinal effect of the medicinal materials to decline, and the calcining efficiency is not high. Summary of the Invention

[0004] This application proposes a traditional Chinese medicine calcining machine, which has the advantages of automatically turning the medicinal materials, preventing the uneven heating caused by the accumulation of medicinal materials, slow heating efficiency, convenient feeding and discharging, and controllable time and temperature, so as to solve the problems of uneven internal and external heating caused by the accumulation of existing medicinal materials and inconvenient feeding and discharging.

[0005] To achieve the above object, this application adopts the following technical solution: A traditional Chinese medicine calcining machine includes: a calcining machine housing for carrying internal devices to form a closed space, and a calcining heating device, a real-time time and temperature control device, and a calcining furnace device are arranged inside the calcining machine housing.

The two sides of the support frame are rectangular in shape, and the middle part is right-angled triangular in shape. Grooves adapted to the movable plate are opened on the two side surfaces of the support frame, that is, the movable plate is slidably connected to the support frame. [[ID=⑩]] [[ID=⑪]]

[0011] [[ID=⑫]]Furthermore, the shape of the closed air-containing plate is rectangular, and the inside of the closed air-containing plate is hollow. The opening size and opening position of the ventilation slot are adapted to the gap size and gap position between one side surface of the heating resistance wire plate and the inner cavity side wall of the heat preservation layer. [[ID=⑬]] [[ID=⑭]]

[0012] Further, the medicine stirring component includes a movable rotating rod, one end of the movable rotating rod is movably installed inside the closed air-containing plate and penetrates through the inner and outer surfaces of the closed air-containing plate. On one side surface of one end of the movable rotating rod, an air pipe is fixedly installed. One end of the air pipe is fixedly installed with a second suction and exhaust pump. The outer surface of the movable rotating rod is fixedly installed with stirring blades. Air outlet holes are formed on both the inner and outer surfaces of the stirring blades. The movable rotating rod and the air pipe are both cylindrical pipe bodies, and the interiors of the movable rotating rod and the air pipe are both hollow. The suction ports of the second suction and exhaust pump are all oriented towards the position where the ventilation slots are located, and the exhaust ports are connected to the openings at one end of the air pipe.

[0014] The present application has the following beneficial effects:

[0015] A traditional Chinese medicine calcining machine provided by the present application, by setting a medicine stirring component and using the cyclic rotation of the stirring blades, enables the overall medicinal materials to form a reciprocating cyclic transportation, so that the heating resistance wire plate uniformly heats all the medicinal materials, making the internal and external heating of the medicinal materials uniform, effectively improving the quality of medicine calcination, enhancing the quality of calcined medicine, strengthening the medicinal effect of the medicinal materials, achieving the effect of improving the retention degree of the medicinal effect, preventing the medicinal materials from piling up and being heated statically, resulting in uneven internal and external heating of the medicinal materials, and further causing problems such as undercooked or burnt medicinal materials.

[0016] Meanwhile, by further setting the first suction pump and the second suction pump, the high-temperature gas in the inner cavity of the medicine calcining furnace body is discharged into the interior of the movable rotating rod under the action of the first suction pump and the second suction pump, and finally sprayed out through the air outlet. The sprayed air flow gives an impact force to the medicinal materials on the surface of the stirring blades, so that the medicinal materials are washed apart, and thus the distance between the medicinal materials is increased, further avoiding secondary accumulation, making the heating area of the medicinal materials more comprehensive, and the air flow being at a high temperature. When washing apart the medicinal materials, the gas will also heat and calcine the surface of the medicinal materials, so that each medicinal material can be subjected to all-round high-temperature calcination and baking, further enhancing the effect of uniform calcination of the medicinal materials, greatly improving the quality and grade of the calcined medicine, improving the efficiency of medicine calcination, preventing the formation of new medicinal material accumulation on the surface of the stirring blades, which may lead to poor and incomplete uniform calcination effect of the medicinal materials. Moreover, when the high-temperature gas flows around the outer surface of the heating resistance wire plate, a large amount of the heat energy of the heating resistance wire plate itself can be retained, avoiding a large amount of heat energy dissipation, thus effectively improving the heating effect of high-temperature calcination of the medicinal materials inside the medicine calcining furnace body, improving the calcination efficiency, and the high-temperature gas as a whole circulates, achieving the effects of recycling, saving energy, and improving efficiency.

[0017] In addition, by providing air outlets on both the inner surface and the outer surface of the stirring blades, when the medicinal materials fall, the air flow discharged from the air outlets is used to buffer the air pressure of the falling medicinal materials, and the air pressure is used to slow down the falling impact force of the medicinal materials, thereby reducing the degree of breakage of the medicinal materials when they fall, greatly retaining the integrity of the medicinal materials, improving the medicinal efficacy of the medicinal materials, and preventing the premature breakage of the medicinal materials from affecting the normal calcination effect.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Example

[0030] Please refer to Figures 1 - 8 , a traditional Chinese medicine calcining machine, comprising: an outer shell 1 of the medicine calcining machine, which is used to carry the internal devices and form a closed space. Inside the outer shell 1 of the medicine calcining machine, there are arranged a medicine calcining heating device, a real-time timing and temperature control device, and a medicine calcining furnace device.

[0031] The medicine calcining heating device is used to create a high-temperature environment for high-temperature calcination of medicinal materials. The medicine calcining heating device is composed of a heat insulation layer 2 and a heating resistance wire plate 3. The heat insulation layer 2 is fixedly installed on the inner cavity top wall surface of the outer shell 1 of the medicine calcining machine, and the heating resistance wire plates 3 are fixedly installed on both sides of the inner cavity of the heat insulation layer 2.

[0032] A real-time time and temperature control device is used to detect the temperature inside the outer shell 1 of the medicine calcining machine in real time, and judge whether to cut off the power supply to stop heating according to the temperature required for medicine calcining. The real-time time and temperature control device consists of a thermocouple 4 and an existing electric control device. The thermocouple 4 is fixedly installed in the top inner cavity of the outer shell 1 of the medicine calcining machine, and the bottom end of the thermocouple 4 penetrates through the outer shell 1 and the heat preservation layer 2 of the medicine calcining machine and extends into the inner cavity of the heat preservation layer 2. The heating resistance wire plate 3 and the thermocouple 4 respectively form a circuit with the existing electric control device. By setting the heating resistance wire plate 3 and the thermocouple 4, when the temperature in the inner cavity of the heat preservation layer 2 reaches the medicine forging temperature, the thermocouple 4 converts the thermal signal into an electric signal and transmits it to the existing electric control device. After receiving the signal, the electric control device then controls whether to supply power to the heating resistance wire plate 3 again according to the working time set by the existing manual. If the temperature reaches the appropriate temperature and the calcining duration is sufficient, the electric control device can perform a power-off operation on the heating resistance wire plate 3, so that the heating resistance wire plate 3 cuts off the power supply and stops heating. After the temperature drops, the next discharging work can be carried out. Therefore, through the thermocouple 4, the real-time time and temperature control effect of the medicine can be achieved.

[0033] A medicine calcining furnace device is used to carry the medicine, facilitate medicine calcining heating, and feeding and discharging work. The medicine calcining furnace device consists of a movable support plate 6, a support frame 7, a medicine calcining furnace body 8, a movable hinge 9, a movable plate 10, a closed air-containing plate 11, a ventilation slot 12, a medicine stirring component 13, a heat insulation sleeve rod 14, a motor 15 and a heat insulation handle 17. The movable support plate 6 is movably installed on the bottom surface of the inner cavity of the outer shell 1 of the medicine calcining machine. The movable support plate 6 is slidably connected to the bottom surface of the inner cavity of the outer shell 1 of the medicine calcining machine and the bottom surface of the heat preservation layer 2. One end of the top of the movable support plate 6 is fixedly connected to a support frame 7. One side of the bottom of the support frame 7 is movably installed with a medicine calcining furnace body 8, and the medicine calcining furnace body 8 is located above the top end of the movable support plate 6. The medicine calcining furnace body 8 is hinged to the support frame 7 through a movable hinge 9. One side surface of the top of the support frame 7 is movably installed with a movable plate 10. A closed air-containing plate 11 is fixedly installed at the bottom of the movable plate 10. Two sides of one side surface of the closed air-containing plate 11 are provided with ventilation slots 12. A medicine stirring component 13 located in the inner cavity of the medicine calcining furnace body 8 is movably installed inside the closed air-containing plate 11. One end of the medicine stirring component 13 is fixedly installed with a heat insulation sleeve rod 14. One end of the heat insulation sleeve rod 14 is fixedly installed with a motor 15. A heat insulation handle 17 is fixedly installed on one side surface of the movable plate 10.

[0034] An electric telescopic rod 5 is provided outside one side of the bottom of the outer shell 1 of the medicine calcining machine. A first suction and exhaust pump 16 is fixedly installed on the top of one side surface of the heat preservation layer 2.

[0035] Please refer to Figures 1 - 8, wherein, the movable support plate 6 is in an "L" shape, the thickness of the gap between the bottom surface of the inner cavity of the medicine calcining machine housing 1 and the bottom surface of the heat insulation layer 2 is adapted to the thickness of the movable support plate 6, and a rectangular protrusion is provided on one side of the medicine calcining machine housing 1. The two sides of the support frame 7 are rectangular in shape, and the middle part is in a right triangle shape. Grooves adapted to the movable plate 10 are provided on the two side surfaces of the support frame 7, that is, the movable plate 10 is slidably connected to the support frame 7. By providing the movable plate 10 and the closed air-containing plate 11, after the medicinal materials are calcined, the heat insulation handle 17 is used to drive the movable plate 10 to rise, and then drive the closed air-containing plate 11 to rise. After the closed air-containing plate 11 completely rises, the top of the electric telescopic rod 5 is moved upward, and then the bottom end of the medicine calcining furnace body 8 is pressed, so that the medicine calcining furnace body 8 tilts upward. When the medicine calcining furnace body 8 tilts upward, at this time, the medicinal materials that have been calcined inside the medicine calcining furnace body 8 will slide down obliquely along the surface of the medicine calcining furnace body 8, thus realizing automatic discharging.

[0036] Please refer to Figures 1 - 8 , wherein, the closed air-containing plate 11 is rectangular in shape, and the inside of the closed air-containing plate 11 is hollow. The opening size and opening position of the air vent slot 12 are adapted to the gap size and gap position between the side surface of one side of the heating resistance wire plate 3 and the inner cavity side wall of the heat insulation layer 2.

[0037] Please refer to Figures 1 - 8, wherein the medicine stirring assembly 13 includes a movable rotating rod 1301, one end of the movable rotating rod 1301 is movably mounted inside the closed air-containing plate 11, and passes through the inner and outer surfaces of the closed air-containing plate 11, a ventilation pipe 1302 is fixedly mounted on one side surface of one end of the movable rotating rod 1301, a second suction air pump 1303 is fixedly mounted on one end of the ventilation pipe 1302, a stirring blade 1304 is fixedly mounted on the outer surface of the movable rotating rod 1301, and air outlet holes 1305 are provided on the inner and outer surfaces of the stirring blade 1304, and the movable rotating rod 1301 and the ventilation pipe 1302 are both cylindrical tubes , and the interior of the movable rotating rod 1301 and the vent pipe 1302 are both hollow, the air inlet of the second suction air pump 1303 is directed toward the location of the vent slot 12, and the air outlet is connected to an opening at one end of the vent pipe 1302, the stirring blade 1304 is in an arc shape, and the interior of the stirring blade 1304 is hollow, there are a number of stirring blades 1304, and the stirring blades 1304 are evenly distributed in a circular shape on the outer surface of the movable rotating rod 1301, the diameter of the air outlet 1305 is much smaller than the length and width of the medicinal material, and the stirring blade 1304 and the interior of the movable rotating rod 1301 interpenetrate each other There are two medicine stirring components 13, and they are respectively located in the inner cavity of the medicine calcining furnace body 8. By setting the medicine stirring components 13, when the medicinal materials are calcined, the motor 15 is used to drive the heat insulation sleeve rod 14 to rotate, and then the heat insulation sleeve rod 14 is used to drive the medicine stirring components 13 to rotate. When the medicine stirring components 13 rotate, the stirring blades 1304 are used to continuously dig out the medicinal materials in the middle of the inner cavity of the medicine calcining furnace body 8, so that the medicinal materials are scooped up on the concave surface of the stirring blades 1304 and are taken away as the stirring blades 1304 rotate. Then, the stirring blades 1304 are circulated to rotate, so that the medicinal materials in the middle are It is continuously transported to both sides, and the medicinal materials on both sides are continuously transported to the middle, thus forming an overall reciprocating circulation transportation of the medicinal materials, so that all the medicinal materials are affected by the rotation of the stirring blades 1304 and pass through the surface of the heating resistance wire plate 3 in turn, thereby achieving the effect of uniform heating of the medicinal materials by the heating resistance wire plate 3, so that the heating inside and outside of the medicinal materials are uniformly and consistently, effectively improving the calcination quality of the medicinal materials, improving the quality of the calcined medicines, strengthening the efficacy of the medicinal materials, and improving the degree of retention of the efficacy, preventing the accumulation of medicinal materials and static heating, which leads to uneven heating inside and outside the medicinal materials, and then causing the problem of undercooked or burnt medicinal materials.

[0038] In addition, although the stirring blade 1304 is used to circulate and transport the medicinal materials to achieve uniform heating of the medicinal materials, when a part of the medicinal materials are dug out by the stirring blade 1304, the medicinal materials staying in the recesses of the stirring blade 1304 will also form a small stack-shaped accumulation to a certain extent, and thus the all-round heating of the medicinal materials is still not fully achieved. Therefore, by setting the first suction pump 16 and the second suction pump 1303, the first suction pump 16 is used to suck the gas in the inner cavity of the medicinal material calcining furnace body 8. Since the gas inside the medicinal material calcining furnace body 8 is affected by the high temperature of the heating resistance wire plate 3 and will have a certain high temperature, this high temperature is generally equal to or less than the surface temperature of the heating resistance wire plate 3. Then, when the first suction pump 16 sucks this part of the high-temperature gas, the high-temperature gas is discharged by the first suction pump 16 into the gaps between the outer shell 1 of the medicinal material calcining machine and the heat insulation layer 2 and between the heat insulation layer 2 and the heating resistance wire plate 3. The gas first passes through the gap between the outer shell 1 of the medicinal material calcining machine and the heat insulation layer 2, and then passes through the gap between the heat insulation layer 2 and the heating resistance wire plate 3, and finally flows to the ventilation slot 12. Also, because the operation of the second suction pump 1303 generates a negative pressure adsorption effect, the gas is sucked by the second suction pump 1303 through the ventilation slot 12 and discharged into the inside of the movable rotating rod 1301. After passing through the inner cavity of the movable rotating rod 1301, the gas then passes through the stirring blade 1304 and the air outlet holes 1305 and is finally discharged outward. When the gas is discharged from the air outlet holes 1305, since the gas is continuously transported and has a certain high temperature, it has a certain pressure. Therefore, when passing through the air outlet holes 1305, the gas will form a small high-pressure air flow and spray outward. The sprayed air flow gives an impact force to the medicinal materials on the surface of the stirring blade 1304, so that the medicinal materials are scattered, increasing the distance between the medicinal materials. And the air flow has a high temperature. When the medicinal materials are flushed open, the gas will also heat and calcine the surface of the medicinal materials. Therefore, on the one hand, the air flow can flush open the medicinal materials, scatter the medicinal materials, avoid the sticking of the medicinal materials, improve the calcining efficiency of the medicinal materials, prevent the formation of new medicinal material accumulations on the surface of the stirring blade 1304, which may lead to poor and incomplete uniform calcining effect of the medicinal materials. On the other hand, it can make the gas shuttle between the medicinal materials and bake and heat the surface of the medicinal materials with gas, so that each medicinal material can be subjected to all-round high-temperature calcination and baking, further strengthening the effect of uniform calcination of the medicinal materials and greatly improving the quality and grade of the calcined medicinal materials.

[0039] In addition, by providing air vents 1305 on both the inner and outer surfaces of the stirring blade 1304, when the stirring blade 1304 rotates with the medicinal materials to the uppermost position, the medicinal materials will fall off the concave surface of the stirring blade 1304. When the medicinal materials are falling, the airflow discharged from the air vents 1305 is used to buffer the air pressure of the falling medicinal materials, and the air pressure is used to slow down the falling impact force of the medicinal materials, thereby reducing the degree of breakage of the medicinal materials when they fall, preventing the medicinal materials from being prematurely broken and affecting the normal calcination effect. The problem that the falling of the medicinal materials mentioned here is broken and affects the normal calcination of the medicinal materials needs to be judged according to the characteristics of the medicinal materials themselves whether there is a problem affecting the normal calcination of the medicinal materials. For example, for ore medicinal materials, there is no high requirement for retaining the structure of the medicinal materials themselves during calcination, that is, the breakage of the medicinal materials during calcination will not affect the calcination effect of the medicinal materials, so the breakage problem existing during the cyclic transportation of the medicinal materials affected by the stirring blade 1304 can be ignored. If it is a shellfish medicinal material, based on the preparation characteristics of the shellfish medicinal material itself, some special shellfish medicinal materials require a certain initial shape to be retained during calcination. Therefore, if the medicinal materials are severely broken during calcination, there may be a problem affecting the normal calcination of the medicinal materials. Therefore, in order to fully adapt to the calcination of various medicinal materials, the airflow jet from the air vents 1305 is used to enable the medicinal materials to greatly retain their initial shape during calcination, thereby improving the retention of the medicinal effect during medicine calcination, avoiding large-area breakage of the medicinal materials, and fully improving the quality of medicinal material calcination.

[0040] Meanwhile, after the first suction pump 16 sucks the high-temperature gas in the inner cavity of the medicine calcining furnace body 8, and the high-temperature gas is discharged, the high-temperature gas can only flow in the gaps between the medicine calcining machine housing 1 and the heat insulation layer 2, and between the heat insulation layer 2 and the heating resistance wire plate 3. Since the temperature difference between the high-temperature gas and the surface temperature of the heating resistance wire plate 3 is small, when the high-temperature gas flows around the outer surface of the heating resistance wire plate 3, less heat energy is conducted outward by the heating resistance wire plate 3. Even when the internal temperature of the heating resistance wire plate 3 is the same as the temperature of the high-temperature gas flowing around outside, the heating resistance wire plate 3 will not conduct heat, thus no heat loss will be caused. Therefore, by allowing the high-temperature gas to flow in the interlayer between the heat insulation layer 2 and the heating resistance wire plate 3, a large amount of the heat energy of the heating resistance wire plate 3 itself can be retained, avoiding a large amount of heat energy dissipation, thereby effectively improving the heating effect of the high-temperature calcination of the medicinal materials inside the medicine calcining furnace body 8, improving the calcination efficiency. Moreover, the high-temperature gas is sucked out by the first suction pump 16, passes through the gap between the heat insulation layer 2 and the heating resistance wire plate 3, is then sucked into by the second suction pump 1303, and is discharged outward through the air outlet 1305, and is discharged back into the inner cavity of the medicine calcining furnace body 8 again. Thus, the high-temperature gas as a whole flows in a cycle, achieving the effects of recycling, saving energy, and improving efficiency. Compared with the existing technology that only relies on the heat insulation layer 2 to insulate the heat of the heating resistance wire plate 3, although due to the non-thermally conductive property of the heat insulation layer 2 itself, a certain high-temperature environment can be retained in the inner cavity of the heat insulation layer 2, the heat insulation layer 2 is not completely non-thermally conductive, but only has slow heat conduction and a small thermal conductivity coefficient. Therefore, a part of the heat energy will still be dissipated, which will lead to poor heating effect and low efficiency of the medicinal materials calcination inside the medicine calcining furnace body 8. If the heating effect is to be improved, the heating time needs to be extended, which will cause problems of time-consuming and energy-consuming. Therefore, through the device of the present invention, not only can the heating effect of the medicinal materials calcination be effectively enhanced, but also time and energy can be saved, fully improving the overall efficiency of the device.

[0041] Please refer to Figures 1 - 8 , in which, the heat insulation sleeve rod 14 has heat insulation property. The air suction port of the first suction pump 16 faces the inner cavity of the heat insulation layer 2, and the air outlet faces the gap between the heat insulation layer 2 and the medicine calcining machine housing 1. Moreover, the surface of the first suction pump 16 is coated with heat insulation paint. The air suction port of the first suction pump 16 is provided with a screen made of high-temperature resistant material, and the screen only allows gas to pass through and does not allow medicinal materials to pass through.

[0042] The working principle of the usage method of the present invention is as follows:

[0043] When traditional Chinese medicine needs to be calcined, manually grasp the handle rod of the heat insulation handle 17 by hand, and slide through the slide rail between the support plate 6 and the outer shell 1 and the heat insulation layer 2 of the calcining machine, so as to pull out the entire calcining furnace device outward. After the calcining furnace is completely pulled out, manually fill the medicinal materials to be calcined into the inner cavity of the calcining furnace body 8 by hand. At this time, it is necessary to ensure that the airtight plate 11 is located at the position facing the inner cavity of the calcining furnace body 8, that is, the bottom of the airtight plate 11 is closely attached to the inner side wall of the bottom of the calcining furnace body 8. Furthermore, the entire inner cavity of the calcining furnace body 8 can form a closed state. When the inner cavity of the calcining furnace body 8 is almost filled, stop loading the medicine. After the medicinal materials are filled, manually push the calcining furnace device inward by holding the heat insulation handle 17, so that the calcining furnace device returns to the inner cavity of the heat insulation layer 2 again. When the calcining furnace device is completely pushed back into the inner cavity of the heat insulation layer 2, at this time, confirm that the outer shell 1 of the calcining machine, the moving plate 10 and the airtight plate 11 are closely attached and sealed to each other. After confirmation, the electric control device in the existing calcining machine can be started, and then the electric telescopic rod 5, the motor 15 and the first suction pump 16 are started. Among them, the electric telescopic rod 5, the motor 15 and the first suction pump 16 are respectively connected to the electric control device, and the electric control device controls the opening and closing of the electric telescopic rod 5, the motor 15 and the first suction pump 16. After starting, power is supplied to the heating resistance wire plate 3, the thermocouple 4, the motor 15 and the first suction pump 16 respectively through the electric control device. After the heating resistance wire plate 3 is powered on, it starts to heat, thus generating a large amount of heat energy to bake the medicinal materials in the inner cavity of the calcining furnace body 8 at a high temperature. At the same time, the thermocouple 4 is powered on and operates to timely detect the environmental temperature in the inner cavity of the calcining furnace body 8. After the first suction pump 16 is powered on, it starts to continuously extract the high-temperature gas in the inner cavity of the calcining furnace body 8. After the motor 15 is powered on, it starts to operate, thus driving the heat insulation sleeve rod 14 to rotate. When the heat insulation sleeve rod 14 rotates, the heat insulation sleeve rod 14 drives the medicine stirring component 13 to rotate. When the medicine stirring component 13 rotates, the stirring blades 1304 will continuously and reciprocally dig the medicinal materials in the middle of the inner cavity of the calcining furnace body 8, so that the medicinal materials in the middle are dug to the concave surface of the stirring blades 1304 and are taken away by the stirring blades 1304 as the stirring blades 1304 rotate. When the stirring blades 1304 rotate to both sides, at this time, the medicinal materials carried inside the stirring blades 1304 will be baked at a high temperature by the heating resistance wire plates 3 on both sides, so that the medicinal materials are fully calcined. Then, through the cyclic rotation of the stirring blades 1304, the medicinal materials are sent back to the middle again. In this way, the medicinal materials in the middle are transported to both sides, and the medicinal materials on both sides are transported to the middle. Then, the medicinal materials in the middle return to the middle again, and the medicinal materials on both sides also return to both sides. Therefore, through the cyclic and continuous rotation of the two groups of medicine stirring components 13, a reciprocating transportation process from the inside to the outside is formed for the medicinal materials in the inner cavity of the calcining furnace body 8, and thus all the medicinal materials are affected by the rotation of the stirring blades 1304 and pass through the surface of the heating resistance wire plate 3 in turn.Thus, the heating resistance wire plate 3 can uniformly heat all the medicinal materials, making the internal and external heating of the medicinal materials uniform and consistent.

[0044] Meanwhile, the first suction pump 16 continuously extracts the high-temperature gas inside the calcining furnace body 8, and then discharges the high-temperature gas into the gap between the calcining machine housing 1 and the heat insulation layer 2 through the first suction pump 16. When the gas is discharged into the gap between the calcining machine housing 1 and the heat insulation layer 2, the gas will flow outwards through the gap between the two side heat insulation layers 2 and the heating resistance wire plate 3. Since the calcining machine housing 1, the moving plate 10, and the closed air-containing plate 11 form a relatively sealed state, only the gap cavities between the calcining machine housing 1 and the heat insulation layer 2, and between the heat insulation layer 2 and the heating resistance wire plate 3 allow the gas to flow. Thus, the gas flows along the gap cavities to the ventilation slot 12 respectively. When the gas reaches the ventilation slot 12, the second suction pump 1303 sucks the gas and discharges it into the inside of the movable rotating rod 1301. After passing through the inner cavity of the movable rotating rod 1301, the gas passes through the stirring blades 1304 and the air outlet holes 1305, and finally discharges outwards through the air outlet holes 1305. When the gas discharges from the air outlet holes 1305, the gas will form a small high-pressure airflow and spray outwards. The sprayed airflow gives an impact force to the medicinal materials on the surface of the stirring blades 1304, causing the medicinal materials to be scattered, increasing the distance between the medicinal materials, and the airflow has a high temperature. When the medicinal materials are flushed open, the gas will also heat and calcine the surface of the medicinal materials. Therefore, the calcining efficiency of the medicinal materials is improved, the effect of uniform calcining of the medicinal materials is further enhanced, and the quality and quality of the calcined medicinal materials are greatly improved.

[0045] At the same time, the airflow discharged from the air outlet holes 1305 is used to buffer the air pressure of the falling medicinal materials, and the air pressure is used to slow down the falling impact force of the medicinal materials, thereby reducing the degree of breakage of the medicinal materials during falling and preventing the medicinal materials from being prematurely broken and affecting the normal calcining effect.

[0046] When the thermocouple 4 detects that the internal temperature of the calcining furnace body 8 has reached the required temperature, the thermocouple 4 will convert the thermal signal into an electrical signal, which will be transmitted to the electric control device. After receiving the signal, the electric control device will choose whether to cut off the power in time according to the set time. When the required calcining time has reached the set time value, the electric control device will control the power supply of each component, so that the heating resistance wire plate 3, thermocouple 4, motor 15 and first suction air pump 16 will all stop running. After the device stops, wait for a period of time, and when the temperature of the equipment drops, use the heat-insulating handle 17 manually to pull the calcining furnace device outward as a whole until the calcining furnace is completely pulled out, that is, the movable support plate 6 can no longer move outward. After the calcining furnace device is pulled out, the heat-insulating handle 17 is manually held to pull the movable plate 10 upward, so that the movable plate 10 to be closed and the air-containing plate 11 moves upward, thereby also driving the medicine stirring component 13 to move upward, until the medicine stirring component 13 moves to the inner cavity of the calcining furnace body 8 and is located at the calcining furnace body. The electric control device controls the power supply to energize the electric telescopic rod 5, so that the electric telescopic rod 5 is energized and the telescopic end of the electric telescopic rod 5 moves upward, thereby lifting the bottom of one end of the calcining furnace body 8, thereby forming a tilted state of the calcining furnace body 8. At this time, because the moving plate 10 and the closed air-containing plate 11 are completely moved upward, the end of the calcining furnace body 8 facing the support frame 7 is in an open state, and the middle part of the support frame 7 is a triangular structure, thereby The inclined surfaces of 8 are parallel to each other, so that the medicinal materials inside the calcining furnace body 8 fall by their own gravity under the tilting trend of the calcining furnace body 8 until they fall into the collecting box, thereby achieving the effect of autonomous discharging, avoiding the existing method of manually holding a hook rod to hook the calcining furnace body 8 out from the inside of the calcining machine shell 1, and then manually turning over the calcining furnace body 8 to pour out the medicinal materials from the inside of the calcining furnace body 8. This not only easily leads to manual burns during the pouring process, but also makes the medicinal material discharging efficiency low and is more time-consuming and labor-intensive.

[0047] After the discharge is completed, the electric control device is used to control the electric telescopic rod 5 to reset downward, thereby resetting the calcining furnace body 8. After the calcining furnace body 8 is completely reset, the movable plate 10, the closed air-containing plate 11 and the medicine stirring assembly 13 are reset together by manually holding the heat-insulating handle 17. After the entire device is reset, the next medicinal material calcination work can be carried out.
