[0005] The purpose of the present invention is to solve the problem in the prior art that during the heating and stirring process, since the liquid will boil after reaching a certain boiling point, the bubbles generated by boiling will rise rapidly, carrying the liquid medicine to splash everywhere inside the tank body. After the water is evaporated by heating, the remaining residue will firmly adhere to the stirring structure and other structures, resulting in increased cleaning difficulty.

The first connecting head pulls the rotating head to drive the slider to slide along the track of the fixed sliding plate. And the movement of the slider pulls the fixed sliding plate, causing the fixed sliding plate to gradually tilt up. Therefore, the added medicinal liquid will not contact the filter plate, avoiding the medicinal liquid splashing everywhere after contacting the filter plate.

The air cylinder retracts, and the filter plate is in a horizontal state. When the medicinal liquid is heated and distilled to generate bubbles, the filter plate can block the bubbles, avoiding the bubbles splashing everywhere and causing the residues to firmly adhere to the stirring structure and other structures.

During the liquid adding process, the heat-conducting bent pipe discharges liquid, and the top of the corresponding side starts to take in liquid, so that there is always liquid medicine in the storage tank. The air pump is started, and bubbles rise through the filter plate into the collecting pipe and then into the heat-conducting bent pipe. Since the storage tank stores liquid medicine inside, when water vapor passes through the heat-conducting bent pipe, its temperature will be discharged through the heat-conducting bent pipe and finally absorbed by the liquid medicine, thereby preheating the liquid medicine in the storage tank.

[0013] As a preferred embodiment, the detection member includes a detection module which is fixed on one side of the top end of the concentration tank. A pressure detector is fixedly connected to the bottom end of the detection module. The pressure detector fixedly penetrates through the top end of the concentration tank. During the heating process, the pressure detector detects the internal pressure of the concentration tank in real time. When the internal pressure of the concentration tank exceeds a predetermined value, the detection module can transmit a signal to the cloud, and the cloud transmits a command signal to the control module. Subsequently, the control module controls the rotation speed of the air pump, thereby accelerating the conveying speed of the air pump, enabling the water vapor inside the concentration tank to quickly enter the collection pipe and be discharged, thereby reducing the internal pressure of the concentration tank. When the pressure inside the concentration tank decreases, the rotation speed of the air pump gradually decreases, making the water vapor flow slower and able to stay in the heat-conducting elbow for a longer time, so as to enable a more comprehensive preheating treatment.

[0014] As a preferred embodiment, a gear set is provided at the top end of the stirring rod. A rotating shaft is provided on one side of the gear set. The end of the rotating shaft away from the gear set is drivingly connected to a motor, and the motor is fixedly connected to the concentration tank. The stirring rod is rotatably connected to a support member at the top end of the pull ring. At the bottom end of the stirring rod located on the support plate, a first stirring blade and a second stirring blade are fixedly connected, and the first stirring blade and the second stirring blade are arranged oppositely. Fixed rods are fixedly connected to both sides of the first stirring blade of the stirring rod.

A first runner is fixedly connected to the bottom end of the stirring rod located in the discharge tank. The first runner is drivingly connected to a belt. When the stirring rod rotates, the belt can be driven to rotate through the first runner. The rotation of the discharge rotating plate facilitates the discharge of residues and prevents the residues from blocking in the discharge tank.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, when adding liquid medicine, the cylinder is started, the cylinder drives the lifting rod to rise, the lifting rod drives the pull ring to rise along the trajectory of the stirring rod, the pull ring drives the first connecting head to move, the first connecting head pulls the rotating head to drive the sliding block to slide along the trajectory of the fixed sliding block, and the movement of the sliding block pulls the fixed sliding block, so that the fixed sliding block gradually tilts up, so that the added liquid medicine will not contact the filter plate, and the liquid medicine will not splash around after contacting the filter plate. After the liquid medicine is added to a certain depth at the bottom of the filter plate, the liquid medicine stops, the cylinder retracts, and the filter plate is in a horizontal state. When the liquid medicine is heated and distilled to generate bubbles, the filter plate can block the bubbles, and the bubbles will not splash around, causing the residue to adhere firmly to the stirring structure and other structures.

[0018] 2. In the present invention, the air pump is started, and the bubbles rise through the filter plate into the collecting tube and then into the heat conducting bend. Since the storage tank stores the medicine liquid inside, when the water vapor passes through the heat conducting bend, its temperature will be discharged through the heat conducting bend and finally absorbed by the medicine liquid, so as to preheat the medicine liquid in the storage tank. When the stirring rod rotates, the first rotating wheel can drive the belt to rotate, the belt drives the rotating rod to rotate, the second rotating wheel drives the rotating rod to rotate, and the rotating rod drives the belt to rotate, so that the medicine liquid in the storage tank can fully absorb heat, so as to be heated evenly, and the cooling of the water vapor is accelerated, so that the water vapor can be quickly cooled after entering the collecting tank, and the energy consumption of the condenser is reduced.

[0019] 3. In the present invention, during the heating process, the pressure detector detects the pressure inside the concentration tank in real time. When the pressure inside the concentration tank exceeds a preset value, the detection module can transmit a signal to the cloud, and the cloud transmits a command signal to the control module. The control module then controls the speed of the air pump, thereby accelerating the delivery speed of the air pump, so that the water vapor inside the concentration tank quickly enters the collection pipe and is discharged, thereby reducing the pressure inside the concentration tank. When the pressure inside the concentration tank decreases, the speed of the air pump gradually decreases, so that the water vapor circulates more slowly and can stay in the heat transfer bend for a longer time, thereby enabling a more comprehensive preheating treatment.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 8, the present invention provides a technical solution: a traditional Chinese medicine extraction and concentration device, including a concentration tank 1. The outer wall of the concentration tank 1 is fixedly connected with a protective shell 11. The bottom end of the concentration tank 1 is fixedly connected with a discharge tank 12. A heating pipe 111 is arranged inside the protective shell 11. A stirring assembly is arranged inside the concentration tank 1. A detection component is arranged on one side of the top end of the concentration tank 1. A preheating assembly is arranged on the top end of one side of the concentration tank 1. The preheating assembly includes a storage tank 31. A cooling assembly is arranged at the bottom end of the storage tank 31. The stirring assembly includes a stirring rod 213. The stirring rod 213 is rotatably connected to the middle of the concentration tank 1 and penetrates through the concentration tank 1. A splash-proof assembly is arranged at the top end of the stirring rod 213.

[0032] As Figure 1 - Figure 8 As shown, the splash-proof assembly of the concentration tank 1 includes a support plate 22. The support plate 22 is fixed to the top end inside the concentration tank 1. The stirring rod 213 rotatably penetrates through the middle of the support plate 22. Filter plates 221 are rotatably connected to both sides of the support plate 22. A fixed sliding plate 222 is fixedly connected to the middle of the top end of the filter plate 221. A slider 2221 is slidably connected inside the fixed sliding plate 222. A rotating head 2222 is fixedly connected to the top end of the slider 2221. A pull rod 2223 is rotatably connected to the middle of the rotating head 2222. One end of the pull rod 2223 away from the slider 2221 is rotatably connected to a first connecting head 2231. A pull ring 223 is fixedly connected to one side of the first connecting head 2231. The pull ring 223 is rotatably connected to the top end of the stirring rod 213 located above the support plate 22. A lifting rod 224 is fixedly connected to the top end of the pull ring 223. The top end of the lifting rod 224 penetrates through the concentration tank 1 and is slidably connected to the concentration tank 1. A cylinder 225 is fixedly connected to the top end of the lifting rod 224. The cylinder 225 is fixed to the top end of the concentration tank 1.

[0033] In this embodiment, when adding the liquid medicine, the cylinder 225 is started. The cylinder 225 drives the lifting rod 224 to rise. The lifting rod 224 drives the pull ring 223 to rise along the track of the stirring rod 213. The pull ring 223 drives the first connecting head 2231 to move. The first connecting head 2231 pulls the rotating head 2222 to drive the slider 2221 to slide along the track of the fixed sliding plate 222. And the movement of the slider 2221 pulls the fixed sliding plate 222, causing the fixed sliding plate 222 to gradually tilt up. Therefore, the added liquid medicine will not contact the filter plate 221, avoiding the liquid medicine splashing everywhere after contacting the filter plate 221. After the liquid medicine is added to a certain depth at the bottom end of the filter plate 221, the cylinder 225 retracts, and the filter plate 221 is in a horizontal state. When the liquid medicine is heated and distilled to generate bubbles, the filter plate 221 can block the bubbles, preventing the bubbles from splashing everywhere and causing the residues to firmly adhere to the stirring structure and other structures.

[0034] As Figure 1 - Figure 8As shown, the detection component includes a detection module 23. The detection module 23 is fixed to one side of the top of the concentration tank 1. A pressure detector 231 is fixedly connected to the bottom end of the detection module 23. The pressure detector 231 fixedly penetrates the top of the concentration tank 1. An air pump 32 is fixedly connected to the top of the storage tank 31. A collection pipe 33 is fixedly connected to one side of the air pump 32. The end of the collection pipe 33 away from the air pump 32 fixedly penetrates the top of the concentration tank 1. A control module 321 is fixedly connected to the top of the air pump 32. A heat-conducting elbow 34 is fixedly connected to the bottom end on one side of the air pump 32. The bottom end of the heat-conducting elbow 34 fixedly penetrates the storage tank 31. A liquid inlet pipe 35 is fixedly connected to the bottom end on the side of the storage tank 31 close to the concentration tank 1. The liquid inlet pipe 35 penetrates the storage tank 31. The top end of the liquid inlet pipe 35 penetrates one side of the top of the concentration tank 1. A water pump 36 is fixedly connected to the middle of the liquid inlet pipe 35. The water pump 36 is fixedly connected to the storage tank 31. The cooling assembly includes a collection tank 41. The collection tank 41 is fixed to the bottom of the storage tank 31. A controller 42 is fixedly connected to the side of the top of the storage tank 31 away from the concentration tank 1. A condenser pipe 43 is fixedly connected to the side of the controller 42 close to the concentration tank 1. The condenser pipe 43 fixedly penetrates the collection tank 41. A drain pipe 44 is fixedly connected to the bottom end on the side of the collection tank 41 away from the concentration tank 1. A rotating rod 45 is rotatably connected to the middle of the bottom end of the collection tank 41. The top end of the rotating rod 45 penetrates the collection tank 41 and the storage tank 31 and is rotatably connected to the storage tank 31. A number of second and third stirring blades 453 are arranged in the middle of the rotating rod 45 inside the storage tank 31 and the collection tank 41. A second runner 451 is fixedly connected to the bottom end of the rotating rod 45. A belt 452 is drivingly connected to the middle of the second runner 451.

[0035] In this embodiment, during the liquid addition process, the heat-conducting elbow 34 discharges liquid, and liquid starts to enter at the corresponding top end, so that there is always liquid medicine in the storage tank 31. The air pump 32 is started, and the bubbles rise through the filter plate 221 and enter the collection pipe 33, and then enter the heat-conducting elbow 34. Since the inside of the storage tank 31 stores liquid medicine, when the water vapor passes through the heat-conducting elbow 34, its temperature will be conducted out through the heat-conducting elbow 34 and finally absorbed by the liquid medicine, thereby preheating the liquid medicine in the storage tank 31. The first runner 2110 drives the belt 452 to rotate, the belt 452 drives the rotating rod 45 to rotate, the second runner 451 drives the rotating rod 45 to rotate, and the rotating rod 45 drives the belt 452 to rotate, so that the liquid medicine in the storage tank 31 can fully absorb heat, thus being evenly heated, and accelerating the cooling of the water vapor. Therefore, after the water vapor enters the collection tank 41, it can be quickly cooled, and the energy consumption of the condenser pipe 43 is reduced. Subsequently, after the water vapor enters the collection tank 41, the controller 42 is started, and the condenser pipe 43 starts to refrigerate, so that the water vapor is completely cooled. During the cooling period, the second and third stirring blades 453 inside the collection tank 41 stir the water vapor to make the cooling uniform.

[0036] As Figure 1 -Figure 8 As shown in the figure, a gear set 212 is provided at the top end of the stirring rod 213. A rotating shaft 211 is provided on one side of the gear set 212. The end of the rotating shaft 211 away from the gear set 212 is drivingly connected to a motor 21. The motor 21 is fixedly connected to the concentration tank 1. The stirring rod 213 is rotatably connected to a support member 214 at the top end of the pull ring 223. At the bottom end of the stirring rod 213 located on the support plate 22, a first stirring blade 215 and a second stirring blade 216 are fixedly connected, and the first stirring blade 215 and the second stirring blade 216 are arranged oppositely. Fixed rods 217 are fixedly connected to both sides of the stirring rod 213 where the first stirring blade 215 is located. The end of the fixed rod 217 away from the stirring rod 213 is fixedly connected to a scraping plate 218. The scraping plate 218 is rotatably connected to the inside of the concentration tank 1. The bottom end of the stirring rod 213 rotatably penetrates through the discharge tank 12, and discharge rotating plates 219 are fixedly connected in a circumferential array in the middle of the discharge tank 12. At the bottom end of the stirring rod 213 located in the discharge tank 12, a first runner 2110 is fixedly connected. The first runner 2110 is drivingly connected to a belt 452.

[0037] In this embodiment, during the heating process, the pressure detector 231 detects the pressure inside the concentration tank 1 in real time. When the pressure inside the concentration tank 1 exceeds the predetermined value, the detection module 23 can transmit the signal to the cloud. The cloud transmits the command signal to the control module 321. Subsequently, the control module 321 controls the rotation speed of the air pump 32, thereby accelerating the conveying speed of the air pump 32, so that the water vapor inside the concentration tank 1 quickly enters the collection pipe 33 and is discharged, thereby reducing the pressure inside the concentration tank 1. When the pressure inside the concentration tank 1 decreases, the rotation speed of the air pump 32 gradually decreases, making the water vapor flow slower and able to stay in the heat-conducting elbow 34 for a longer time, so that a more comprehensive preheating treatment can be carried out. When heating, the motor 21 and the heating pipe 111 are started. The motor 21 drives the gear set 212 to rotate. The gear set 212 drives the stirring rod 213 to rotate. The stirring rod 213 drives the first stirring blade 215, the second stirring blade 216, the discharge rotating plate 219 and the first runner 2110 to rotate. The first stirring blade 215 rotates to convey the liquid medicine upward, and the second stirring blade 216 rotates to convey the liquid medicine downward. The two cooperate with each other to make the liquid medicine mix, stir and be heated evenly.

[0038] ​Working principle: First, when adding the liquid medicine, the air cylinder 225 is started. The air cylinder 225 drives the lifting rod 224 to rise. The lifting rod 224 drives the pull ring 223 to rise along the track of the stirring rod 213. The pull ring 223 drives the first connector 2231 to move. The first connector 2231 pulls the rotating head 2222. The rotating head 2222 drives the slider 2221 to slide along the track of the fixed slide plate 222. And the movement of the slider 2221 pulls the fixed slide plate 222, causing the fixed slide plate 222 to gradually tilt up. Therefore, the added liquid medicine will not contact the filter plate 221, avoiding the liquid medicine from splashing everywhere after contacting the filter plate 221. After the liquid medicine is added to a certain depth at the bottom of the filter plate 221, the air cylinder 225 retracts, and the filter plate 221 is in a horizontal state. During the liquid addition process, the heat-conducting elbow 34 discharges liquid, and the liquid starts to enter at the top of the corresponding side, so that there is always liquid medicine in the storage tank 31. After the liquid medicine is added to a certain depth at the bottom of the filter plate 221, the air cylinder 225 retracts, and the filter plate 221 is in a horizontal state. When heating, the motor 21 and the heating pipe 111 are started. The motor 21 drives the gear set 212 to rotate. The gear set 212 drives the stirring rod 213 to rotate. The stirring rod 213 drives the first stirring blade 215, the second stirring blade 216, the discharging rotating plate 219, and the first rotating wheel 2110 to rotate. The first stirring blade 215 rotates to convey the liquid medicine upward, and the second stirring blade 216 rotates to convey the liquid medicine downward. The two cooperate with each other to make the liquid medicine mix, stir, and be heated evenly. After the liquid medicine is heated and distilled, bubbles will be generated. The filter plate 221 can block the bubbles, avoiding the bubbles from splashing everywhere and causing residues to firmly adhere to the stirring structure and other structures. The air pump 32 is started. The bubbles rise through the filter plate 221 and enter the collecting pipe 33, and then enter the heat-conducting elbow 34. Since the inside of the storage tank 31 stores the liquid medicine, when the water vapor passes through the heat-conducting elbow 34, its temperature will be conducted out through the heat-conducting elbow 34 and finally absorbed by the liquid medicine, thereby pre-heating the liquid medicine in the storage tank 31. The first rotating wheel 2110 drives the belt 452 to rotate. The belt 452 drives the rotating rod 45 to rotate. The second rotating wheel 451 drives the rotating rod 45 to rotate. The rotating rod 45 drives the belt 452 to rotate, so that the liquid medicine in the storage tank 31 can fully absorb heat, thus being heated evenly and accelerating the cooling of the water vapor. Therefore, after the water vapor enters the collecting tank 41, it can be quickly cooled, and the energy consumption of the condenser pipe 43 is reduced. Then, after the water vapor enters the collecting tank 41, the controller 42 is started, and the condenser pipe 43 starts to refrigerate, making the water vapor completely cooled. During the cooling period, the second and third stirring blades 453 inside the collecting tank 41 stir the water vapor to make it evenly cooled. During the heating process, the pressure detector 231 continuously detects the pressure inside the concentration tank 1. When the pressure inside the concentration tank 1 exceeds the predetermined value, the detection module 23 can transmit the signal to the cloud. The cloud transmits the command signal to the control module 321. Then, the control module 321 controls the rotation speed of the air pump 32, thereby accelerating the conveying speed of the air pump 32.The water vapor inside the concentration tank 1 can quickly enter the collection pipe 33 and be discharged, thereby reducing the pressure inside the concentration tank 1. After the pressure inside the concentration tank 1 decreases, the rotation speed of the air pump 32 gradually decreases, making the water vapor flow slower and able to stay in the heat-conducting elbow pipe 34 for a longer time, so that a more comprehensive preheating treatment can be carried out.
