Description

Technical Field

[0001] The invention relates to the technical field of extraction devices, in particular to a traditional Chinese medicine microwave extraction device. Background Art

[0002] At present, steam and electric energy are the main heating means for the extraction of traditional Chinese medicine. Heat is first transferred to the surface of the heated object by heat conduction, convection and thermal radiation, and then the temperature of the center of the heated object is gradually increased by heat conduction. Therefore, the external heating method of steam or electric energy for extracting traditional Chinese medicine is inefficient and consumes a lot of energy.

[0003] Microwave heating is an internal heating method. High-frequency electromagnetic waves penetrate the extraction medium. Due to the absorption of microwave energy, the temperature inside the cells rises rapidly, causing the pressure inside the cells to exceed the capacity of the cell wall to expand. The cells are bound to rupture, and the effective ingredients in the cells flow out freely. At the same time, the electromagnetic field generated by the microwaves accelerates the diffusion rate of the extracted medium components to the extraction solvent interface.

A cavity cooperating with the rotating shaft 23 is provided inside the cylindrical cam 24, and a plurality of circular holes 241 connected with the cavity are provided at the bottom of the cylindrical cam 24. A limit strip 232 is fixedly connected to the rotating shaft 23, and a slide groove cooperating with the limit strip 232 is provided in the cylindrical cam 24. A material changing mechanism for discharging the extracted Chinese medicine in the barrel 1 and replenishing the Chinese medicine to be extracted is provided on the barrel 1. The material changing mechanism includes a feed pipe 3 and a discharge box 56 fixedly connected to the barrel 1.

Since the inclined plate 22 is designed to be inclined, and the vertical position of the toggle plate 21 is fixed relative to the cylinder 1, when the toggle plate 21 drives the inclined plate 22 to rotate, the inclined plate 22 also moves axially up and down, and then the rotating shaft 23 fixedly connected to the inclined plate 22 can also axially reciprocate while following the rotation of the inclined plate 22.

[0028] The material changing mechanism also includes a first mounting rod 51 fixedly connected to the cylinder 1, the first mounting rod 51 is fixedly connected to the filter screen 5, the cylindrical cam 24 is slidably connected to a ring 52, the ring 52 is fixedly connected to a ball slider 521 that cooperates with the slide groove on the cylindrical cam 24, the ring 52 is fixedly connected to a rectangular column 522, and the end of the rectangular column 522 away from the ring 52 is fixedly connected to a scraper 53, the scraper 53 is slidably connected to the cylinder 1, and the scraper 53 is in contact with the filter screen 5. The material changing mechanism also includes a fixed connection A mounting plate 523 on the rectangular column 522 has a through hole formed on the mounting plate 523 and is slidably connected to a guide column 541 through the through hole. The two ends of the guide column 541 are respectively fixedly connected to a push plate 54 and a first limit plate 542. The lower surface of the push plate 54 fits with the upper surface of the scraper 53. A first spring 543 is set on the guide column 541. The two ends of the first spring 543 are respectively abutted against the first limit plate 542 and the mounting plate 523. An inclined plate 55 is fixedly connected to the filter screen 5, and the inclined plate 55 intermittently abuts against the push plate 54.

[0029] Reference Figure 1 , Figure 3 and Figure 4 When the rotating shaft 23 rotates, the stirring rod 231 fixedly connected to the rotating shaft 23 is driven by the rotating shaft 23 to rotate, disturbing the Chinese medicine and the extract in the cylinder 1, so that the Chinese medicine is more fully extracted by heat. At the same time, the stirring rod 231 follows the rotating shaft 23 to rise and fall and rotate, which can increase the stirring range of the extract in the cylinder 1 and increase the stirring effect. Since the rotating shaft 23 is slidably connected to the cylindrical cam 24, and the limiting strip 232 set on the rotating shaft 23 slides on the cylindrical cam 24, the rotating rotating shaft 23 can drive the cylindrical cam 24 to rotate, and the rotating shaft 23 can be raised and lowered on the cylindrical cam 24, since a cavity is provided in the cylindrical cam 24, and the circular hole 241 is connected with the cavity in the cylindrical cam 24, when the rotating shaft 23 slides in the cylindrical cam 24, the pressure in the cylindrical cam 24 can show alternating changes between positive pressure and negative pressure, and the extract in the cylinder body 1 can enter the cavity in the cylindrical cam 24 through the circular hole 241, and then be ejected from the cavity in the cylindrical cam 24 through the circular hole 241, disturbing the extract near the cylindrical cam 24 in the cylinder body 1, further making the distribution of the extract and the Chinese medicine uniform, so that the Chinese medicine is heated more uniformly.

[0030] Embodiment 2

[0031] On the basis of Example 1, further, the material changing mechanism also includes a second mounting rod 571 rotatably connected to the discharge box 56, and the second mounting rod 571 is fixedly connected to a box door 57 cooperating with the discharge box 56, both ends of the second mounting rod 571 pass through the discharge box 56 and are fixedly connected to a second limit plate 572, and both ends of the second mounting rod 571 are hooked with a torsion spring 573, and the two ends of the torsion spring 573 are respectively fixedly connected to the discharge box 56 and the second limit plate 572, and the scraper 53 is fixedly connected to a top column 544, and the top column 544 intermittently abuts against the box door 57, and the inner bottom surface of the discharge box 56 is provided with a certain slope.

[0032] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 Since the scraper 53 slides axially in the cylinder 1, the ring 52 fixedly connected to the scraper 53 through the rectangular column 522 will not rotate synchronously with the cylindrical cam 24, and when the cylindrical cam 24 rotates, the ball slider 521 in the ring 52 can slide relatively in the slide groove on the cylindrical cam 24, so that the ring 52 can slide axially back and forth on the cylindrical cam 24, and the ring 52 can drive the scraper 53 and the ring 52 to slide axially up and down synchronously through the rectangular column 522, and the rotating shaft 23 is Figure 3 In this state, the cylinder 1 rotates clockwise constantly, and the extract in the cylinder 1 is stirred by the stirring rod 231 on the rotating shaft 23 to form a vortex. The Chinese medicine that has been added for a long time has absorbed the extract, and the Chinese medicine that has been added for a long time will settle downward. At this time, the vortex formed by the extract being stirred by the stirring rod 231 hits the filter 5 and sticks to the filter 5, and the scraper 53 fits with the filter 5, and then when the scraper 53 is driven by the ring 52 to perform axial lifting and lowering, the Chinese medicine on the filter 5 can be scraped off, and the Chinese medicine can not be separated from the scraper 53 and the filter 5 under the impact of the vortex generated by the extract.

[0033] The material changing mechanism also includes a rotating rod 32 rotatably connected to the feed pipe 3, a spiral piece 321 is fixedly connected to the rotating rod 32, and the spiral piece 321 is in contact with the inner wall of the feed pipe 3. A disc 33 is fixedly connected to one end of the rotating rod 32 located outside the feed pipe 3, and a plurality of protrusions 331 arranged in an annular array are fixedly connected to the disc 33. An L-shaped plate 34 is fixedly connected to the feed pipe 3, and a rectangular rod 352 is slidably connected to the L-shaped plate 34. A rectangular plate 35 is fixedly connected to the top of the rectangular rod 352. Two push blocks 351 are fixedly connected to 35, and the two push blocks 351 alternately abut against the multiple protrusions 331 on the disc 33. A second spring 353 is looped on the rectangular rod 352, and the two ends of the second spring 353 respectively abut against the rectangular plate 35 and the L-shaped plate 34. A pull rope 354 is fixedly connected to the box door 57, and one end of the pull rope 354 away from the box door 57 is fixedly connected to the bottom of the rectangular rod 352. A vertical pipe 31 is fixedly connected to the feed pipe 3, and a feeding hopper 311 is fixedly connected to the top of the vertical pipe 31.

[0034] Reference Figure 3 and Figure 7 When the scraper 53 continues to move upward, the push plate 54 arranged on the scraper 53 can move upward synchronously with the scraper 53. As the scraper 53 moves upward, the push plate 54 will eventually contact the inclined plate 55, and then the scraper 53 continues to drive the push plate 54 to move upward, so that the push plate 54 moves toward the discharge box 56 along the inclination of the inclined plate 55 and overcomes the elastic force of the first spring 543. Before the scraper 53 runs to the top, the top column 544 on the push plate 54 first contacts the box door 57, so that the box door 57 overcomes the force of the torsion spring 573 and is pushed open and moves with the scraper 5 3 continues to move upward so that the push plate 54 is closer to the box door 57. At this time, the angle at which the box door 57 is pushed open gradually increases. When the scraper 53 moves to the top, the push plate 54 can completely block the opening of the discharge box 56 located in the cylinder 1. At this time, the pushed plate 54 pushes the filter screen 5 and the Chinese medicine on the scraper 53 into the discharge box 56, and then the Chinese medicine and a small amount of extract fall into the inclined ring 4. As the scraper 53 moves downward, the push plate 54 gradually moves away from the discharge box 56 under the action of the first spring 543. At this time, the box door 57 is closed under the action of the torsion spring 573.

[0035] Embodiment 3

[0036] On the basis of Example 2, further, the material changing mechanism is also provided with a recovery mechanism for recovering the extract from the traditional Chinese medicine discharged from the discharge box 56, the recovery mechanism includes an oblique ring 4 fixedly connected to the cylinder body 1, the oblique ring 4 is located at the lower part of the discharge box 56, the oblique ring 4 is fixedly connected to a recovery groove 41 at the lowest inclined side, and a filter plate 42 is fixedly connected in the recovery groove 41, the recovery mechanism also includes a piston cylinder 6 fixedly connected to the cylinder body 1, an absorption pipe 61 and a discharge pipe 62 are fixedly connected to the piston cylinder 6, and a one-way valve 63 is provided on the absorption pipe 61 and the discharge pipe 62, and the end of the absorption pipe 61 away from the piston cylinder 6 extends into the recovery groove 41, and an addition pipe 14 for adding the extract is fixedly connected to the cylinder body 1, and an end of the discharge pipe 62 away from the piston cylinder 6 is fixedly connected to the addition pipe 14.

[0037] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 When the box door 57 is opened, the box door 57 no longer applies tension to the pull rope 354. At this time, the rectangular plate 35 moves upward under the action of the second spring 353, and the push blocks 351 located at the upper and lower parts of the rectangular plate 35 push the protrusions 331 on the disk 33, so that the disk 33 rotates. When the box door 57 is closed, the box door 57 pulls the rectangular rod 352 downward through the pull rope 354, and then the rectangular plate 35 fixedly connected to the rectangular rod 352 moves downward. At this time, the push block 351 located at the upper part of the rectangular plate 35 pushes the protrusions 331 on the disk 33 The block 331 pushes again, causing the disc 33 to rotate again. The force of the torsion spring 573 is greater than the elastic force of the second spring 353, so that the box door 57 can be opened and closed normally. When the disc 33 rotates, the rotating rod 32 fixedly connected to the disc 33 rotates. At this time, the spiral piece 321 on the rotating rod 32 rotates, and then the Chinese medicine in the hopper 311 falls into the feed pipe 3 through the vertical pipe 31 under gravity, and is then transported to the cylinder 1 by the rotating spiral piece 321, so that the Chinese medicine in the cylinder 1 can be replenished in time after being discharged by the discharge box 56.

[0038] A mounting ring 64 is rotatably connected to the rotating shaft 23, a connecting rod 641 is fixedly connected to the mounting ring 64, a piston rod 642 is fixedly connected to the connecting rod 641, the piston rod 642 is slidably connected in the piston cylinder 6, a tension spring 65 is sleeved on the rotating shaft 23, two ends of the tension spring 65 are respectively fixedly connected to the mounting ring 64 and the cylinder body 1, a discharge pipe 12 is fixedly connected to the bottom of the cylinder body 1, and a blocking plate 13 is rotatably connected to the discharge pipe 12.

[0039] Reference Figure 1-Figure 3Since the inclined ring 4 is provided with a certain inclination, the extract liquid dropped from the discharge box 56 and the extract liquid contained in the Chinese medicine flow into the recovery tank 41 along the inclination of the inclined ring 4, and the filter plate 42 on the recovery tank 41 can prevent the Chinese medicine from entering the recovery tank 41. When the rotating shaft 23 moves up and down axially, the mounting ring 64 rotating on the rotating shaft 23 makes synchronous axial reciprocating motion with the rotating shaft 23. Since the piston cylinder 6 is fixedly connected to the cylinder body 1, and the piston rod 642 fixedly connected to the mounting ring 64 through the connecting rod 641 slides in the piston cylinder 6, the mounting ring 64 will not rotate with the rotating shaft 23, and when the rotating shaft 23 moves up and down axially, the piston rod 642 can be driven to slide back and forth in the piston cylinder 6 through the mounting ring 64. One-way valves 63 are arranged on the cylinder body 1 and the discharge pipe 62, so that when the piston rod 642 moves upward from the piston cylinder 6, the extract in the recovery tank 41 can be absorbed into the piston cylinder 6 through the absorption pipe 61, and when the piston rod 642 moves downward in the piston cylinder 6, the extract absorbed in the piston cylinder 6 can be discharged through the discharge pipe 62, and the discharge pipe 62 is connected with the addition pipe 14, so that the extract can flow back into the cylinder body 1 through the addition pipe 14 to continue to participate in the extraction of the Chinese medicine. After the extraction is completed, the microwave generator 11 and the motor 2 are turned off, and the blocking plate 13 is opened to allow the extract and the Chinese medicine in the cylinder body 1 to flow out from the discharge pipe 12 and receive the extract and the Chinese medicine, and then the discharged extract is filtered to separate the Chinese medicine.

[0040] Working principle: The Chinese medicine microwave extraction device is used to add the extract and part of the Chinese medicine into the cylinder 1 through the adding tube 14, and then the remaining Chinese medicine to be extracted is put into the feeding hopper 311, and the microwave generator 11 and the motor 2 are started;

[0041] When the motor 2 is started, the toggle plate 21 connected to the output end of the motor 2 rotates, and then the rotating toggle plate 21 drives the toggle block 221 on the swash plate 22 to rotate the swash plate 22, and then the rotating shaft 23 connected to the swash plate 22 rotates. Since the swash plate 22 is designed to be inclined, and the vertical position of the toggle plate 21 is fixed relative to the cylinder 1, when the toggle plate 21 drives the swash plate 22 to rotate, the swash plate 22 also moves axially up and down, and then the rotating shaft 23 fixedly connected to the swash plate 22 can also axially reciprocate while following the swash plate 22 to rotate.

[0042] When the rotating shaft 23 rotates, the stirring rod 231 fixedly connected to the rotating shaft 23 is driven by the rotating shaft 23 to rotate, disturbing the Chinese medicine and the extract in the cylinder 1, so that the Chinese medicine is more fully extracted by heat. At the same time, the stirring rod 231 follows the rotating shaft 23 to rise and fall and rotate, which can increase the stirring range of the extract in the cylinder 1 and increase the stirring effect. Since the rotating shaft 23 is slidably connected to the cylindrical cam 24, and the limiting strip 232 set on the rotating shaft 23 slides on the cylindrical cam 24, the rotating rotating shaft 23 can drive the cylindrical cam 24 to rotate, and the rotating shaft 23 can be raised and lowered on the cylindrical cam 24, since a cavity is provided in the cylindrical cam 24, and the circular hole 241 is connected with the cavity in the cylindrical cam 24, when the rotating shaft 23 slides in the cylindrical cam 24, the pressure in the cylindrical cam 24 can show alternating changes between positive pressure and negative pressure, and the extract in the cylinder body 1 can enter the cavity in the cylindrical cam 24 through the circular hole 241, and then be ejected from the cavity in the cylindrical cam 24 through the circular hole 241, disturbing the extract near the cylindrical cam 24 in the cylinder body 1, further making the distribution of the extract and the Chinese medicine uniform, so that the Chinese medicine is heated more uniformly.

[0043] Since the scraper 53 slides axially in the cylinder 1, the ring 52 fixedly connected to the scraper 53 through the rectangular column 522 will not rotate synchronously with the cylindrical cam 24, and when the cylindrical cam 24 rotates, the ball slider 521 in the ring 52 can slide relatively in the slide groove on the cylindrical cam 24, so that the ring 52 can slide axially back and forth on the cylindrical cam 24, and the ring 52 can drive the scraper 53 and the ring 52 to slide axially up and down synchronously through the rectangular column 522, and the rotating shaft 23 is Figure 3 In the state, the extraction liquid in the cylinder 1 rotates clockwise constantly, and then the extraction liquid in the cylinder 1 is stirred by the stirring rod 231 on the rotating shaft 23 to form a vortex, and the Chinese medicine added for a long time has absorbed the extraction liquid, and then the Chinese medicine added for a long time will settle downward. At this time, the vortex formed by the stirring of the extraction liquid by the stirring rod 231 hits the filter screen 5 and sticks to the filter screen 5, and the scraper 53 is in contact with the filter screen 5, and then when the scraper 53 is driven by the ring 52 to perform axial lifting, the Chinese medicine on the filter screen 5 can be scraped off, and the Chinese medicine can not be separated from the scraper 53 and the filter screen 5 under the impact of the vortex generated by the extraction liquid;

[0044] When the scraper 53 continues to move upward, the push plate 54 arranged on the scraper 53 can move upward synchronously with the scraper 53. As the scraper 53 moves upward, the push plate 54 will eventually contact the inclined plate 55, and then the scraper 53 continues to drive the push plate 54 to move upward, so that the push plate 54 moves toward the discharge box 56 along the inclination of the inclined plate 55 and overcomes the elastic force of the first spring 543. Before the scraper 53 runs to the top, the top column 544 on the push plate 54 first contacts the box door 57, so that the box door 57 overcomes the force of the torsion spring 573 and is pushed open and moves with the scraper 53. Continuing to move upward makes the push plate 54 closer to the box door 57. At this time, the angle at which the box door 57 is pushed open gradually increases. When the scraper 53 moves to the top, the push plate 54 can completely block the opening of the discharge box 56 located in the cylinder 1. At this time, the pushed plate 54 pushes the filter screen 5 and the Chinese medicine on the scraper 53 into the discharge box 56, and then the Chinese medicine and a small amount of extract fall into the inclined ring 4. As the scraper 53 moves downward, the push plate 54 gradually moves away from the discharge box 56 under the action of the first spring 543. At this time, the box door 57 is closed under the action of the torsion spring 573;

[0045] When the box door 57 is opened, the box door 57 no longer applies tension to the pull rope 354. At this time, the rectangular plate 35 moves upward under the action of the second spring 353, and the push blocks 351 located at the upper and lower parts of the rectangular plate 35 push the protrusions 331 on the disk 33, so that the disk 33 rotates. When the box door 57 is closed, the box door 57 pulls the rectangular rod 352 downward through the pull rope 354, and the rectangular plate 35 fixedly connected to the rectangular rod 352 moves downward. At this time, the push block 351 located at the upper part of the rectangular plate 35 pushes the protrusions 331 on the disk 33 The block 331 pushes again, causing the disc 33 to rotate again. The force of the torsion spring 573 is greater than the elastic force of the second spring 353, so that the box door 57 can be opened and closed normally. When the disc 33 rotates, the rotating rod 32 fixedly connected to the disc 33 rotates. At this time, the spiral piece 321 on the rotating rod 32 rotates, and then the Chinese medicine in the hopper 311 falls into the feed pipe 3 through the vertical pipe 31 under gravity, and is then transported to the cylinder 1 by the rotating spiral piece 321, so that the Chinese medicine in the cylinder 1 can be replenished in time after being discharged by the discharge box 56.

[0046] Since the inclined ring 4 is provided with a certain inclination, the extract liquid dropped from the discharge box 56 and the extract liquid contained in the Chinese medicine flow into the recovery tank 41 along the inclination of the inclined ring 4. The filter plate 42 on the recovery tank 41 can prevent the Chinese medicine from entering the recovery tank 41. When the rotating shaft 23 moves up and down axially, the mounting ring 64 rotating on the rotating shaft 23 makes synchronous axial reciprocating motion with the rotating shaft 23. Since the piston cylinder 6 is fixedly connected to the cylinder body 1, and the piston rod 642 fixedly connected to the mounting ring 64 by the connecting rod 641 slides in the piston cylinder 6, the mounting ring 64 will not rotate with the rotating shaft 23, and the rotating shaft 23 will not rotate. When the piston rod 642 moves up and down, the mounting ring 64 can drive the piston rod 642 to slide back and forth in the piston cylinder 6. Since the one-way valve 63 is arranged on the absorption tube 61 and the discharge tube 62, when the piston rod 642 moves upward from the piston cylinder 6, the extraction liquid in the recovery tank 41 can be absorbed into the piston cylinder 6 through the absorption tube 61. When the piston rod 642 moves downward in the piston cylinder 6, the extraction liquid absorbed in the piston cylinder 6 can be discharged through the discharge tube 62. The discharge tube 62 is connected with the addition tube 14, and the extraction liquid can flow back into the cylinder body 1 through the addition tube 14 to continue to participate in the extraction of traditional Chinese medicine.

[0047] After the extraction is completed, turn off the microwave generator 11 and the motor 2, open the blocking plate 13 to allow the extract and the Chinese medicine in the cylinder 1 to flow out from the discharge pipe 12 and receive the extract and the Chinese medicine, and then filter the discharged extract to separate the Chinese medicine.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
