[0034] See also Figure 1-6 The present invention provides a technical solution: a traditional Chinese medicine evaporation and concentration device, comprising a medicine barrel 1, a heating part 2, a buoyancy part and a shielding tube 3, the medicine barrel 1 is a cylindrical structure with an upper end open and a lower end closed, the heating part 2 can be an electric furnace, the heating part 2 is used to heat the medicine barrel 1, the buoyancy part is located in the medicine barrel 1, the buoyancy part is used to float in the traditional Chinese medicine liquid, the buoyancy part is an annular structure matched with the inner cavity of the medicine barrel 1, the shielding tube 3 is fixedly connected to the buoyancy part and is arranged coaxially with the buoyancy part, and the upper end of the shielding tube 3 is located above the buoyancy part.

[0035] When using the Chinese medicine evaporation and concentration device described in the present invention to concentrate Chinese medicine, the medicine barrel 1 is placed on the heating part, the Chinese medicine liquid to be concentrated is added into the medicine barrel 1, and then the heating part 2 is used to heat the medicine barrel 1, which can make the Chinese medicine boil and evaporate in the medicine barrel 1, so as to achieve evaporation and concentration of the Chinese medicine.

[0036] After adding Chinese medicine liquid into the medicine barrel 1, the buoyancy part can float on the liquid surface of the Chinese medicine liquid, and the water vapor evaporated from the Chinese medicine can be quickly discharged upward through the annular hole of the annular structure formed by the buoyancy part and the inner cavity of the shielding tube 3. The shielding tube 3 can block the Chinese medicine droplets splashing from the Chinese medicine, can reduce the Chinese medicine droplets splashing to the part of the barrel wall of the medicine barrel 1 located above the Chinese medicine liquid surface, can reduce the contamination marks formed by the Chinese medicine droplets on the barrel wall that are difficult to clean, and save more effort when cleaning the medicine barrel 1 later.

[0037] In this embodiment, the shielding tube 3 is a structure that can be retracted vertically;

[0038] It also includes a support ring 4 and a plurality of support blocks 5. The support ring 4 is fixedly mounted on the upper end of the shielding tube 3 and is coaxially arranged with the shielding tube 3. The plurality of support blocks 5 are fixedly connected to the support ring 4 and are evenly arranged around the support ring 4 in a circumferential direction. The support blocks 5 are supported on the upper end of the medicine barrel 1.

[0039] During the evaporation and concentration process of traditional Chinese medicine, the liquid level of the traditional Chinese medicine will gradually decrease, and the buoyancy part will decrease along with the liquid level of the traditional Chinese medicine. The upper end of the shielding tube 3 is supported on the upper end of the medicine barrel 1 by the support ring 4 and the plurality of support blocks 5, so that the upper end of the shielding tube 3 can be not lower than the upper end of the medicine barrel 1. The shielding tube 3 is a structure that can be retracted vertically. During the process of the buoyancy part descending in the medicine barrel 1, the shielding tube 3 can be extended. During the entire process of evaporating and concentrating the traditional Chinese medicine, the shielding tube 3 can always shield the entire part of the barrel wall of the medicine barrel 1 located above the liquid level of the traditional Chinese medicine, which can further reduce the splashing of traditional Chinese medicine droplets adhering to the barrel wall of the medicine barrel 1 located above the liquid level of the traditional Chinese medicine, and can further reduce the difficult-to-clean pollution marks formed on the barrel wall by the traditional Chinese medicine droplets, which is more labor-saving when cleaning the medicine barrel 1 later.

[0040] In this embodiment, the shielding tube 3 is a cylindrical structure made of gauze, so that the shielding tube 3 is a flexible structure as a whole, so that the shielding tube 3 can be compressed and wrinkled in the vertical direction, and the compressed shielding tube 3 can be stretched and restored to its shape. With this structure, the shielding tube 3 is a structure that can be retracted and extended vertically.

[0041] In this embodiment, the buoyancy part includes a buoyancy ring 6 and a wiping ring, the buoyancy ring 6 is used to float on the surface of the Chinese medicine liquid, the wiping ring is fixedly arranged at the upper end of the buoyancy ring 6 and is arranged coaxially with the buoyancy ring 6, the wiping ring is matched with the inner cavity of the medicine barrel 1, and the outer peripheral surface of the wiping ring abuts against the inner peripheral surface of the medicine barrel 1. With this structure, the buoyancy part can be an annular structure matched with the inner cavity of the medicine barrel 1.

[0042] In the process of the Chinese medicine liquid level falling, the buoyancy ring 6 can fall with the Chinese medicine liquid level, and the wiping ring can fall with the buoyancy ring 6 and wipe downward the Chinese medicine liquid remaining on the barrel wall of the medicine barrel 1 due to the falling Chinese medicine liquid level. The Chinese medicine liquid remaining on the part of the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring can be reduced, and the contamination marks formed on the wall of the medicine barrel 1 can be reduced, which saves more effort when cleaning the medicine barrel 1 later.

[0043] In this embodiment, the buoyancy ring 6 is a hollow metal ring structure, so that the overall average density of the buoyancy ring 6 can be less than the sealing of water, so that the buoyancy ring 6 can float on the liquid surface of the traditional Chinese medicine.

[0044] In this embodiment, an exhaust pipe 7 is provided in the buoyancy ring 6, one end of the exhaust pipe 7 is connected to the outer peripheral surface of the upper end of the buoyancy ring 6, and the other end of the exhaust pipe 7 is connected to the upper end of the ring hole wall of the buoyancy ring 6. Through the exhaust pipe 7, water vapor in the space surrounded by the outer peripheral surface of the buoyancy ring 6, the wall of the medicine barrel 1, the Chinese medicine liquid surface and the lower side of the wiping ring is conveniently discharged.

[0045] In this embodiment, the outer circumferential surface of the wiping ring is inwardly recessed to form an annular groove 8, and water is contained in the annular groove 8. The water in the annular groove 8 can be sealed in the annular groove 8 by the barrel wall of the medicine barrel 1. When the wiping ring descends with the buoyancy ring 6 and wipes downward the Chinese medicine liquid remaining on the barrel wall of the medicine barrel 1 due to the drop in the liquid level of the Chinese medicine liquid, the annular groove 8 and the water in the annular groove 8 will also move downward, and the residual liquid medicine at the position on the barrel wall of the medicine barrel 1 corresponding to the annular groove 8 after being wiped by the part of the wiping ring located on the lower side of the annular groove 8 can be mixed into the water in the annular groove 8, which can further reduce the Chinese medicine remaining on the part of the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring, and can further reduce the pollution marks formed on the wall of the medicine barrel 1, which is more labor-saving when cleaning the medicine barrel 1 later.

[0046] In this embodiment, a water adding portion and a water draining portion are further included. The water adding portion is used to add water into the annular groove 8 , and the water draining portion is used to drain the water in the annular groove 8 .

[0047] In the process that the wiping ring descends with the buoyancy ring 6, water can be added to the annular groove 8 through the water adding part and the water in the annular groove 8 can be discharged through the drainage part, the water mixed with the Chinese medicine liquid in the annular groove 8 can be replaced by water without the Chinese medicine liquid, and the concentration of the Chinese medicine liquid in the water in the annular groove 8 can be reduced. In the process that the annular groove 8 moves downward, the concentration of the Chinese medicine in the water remaining on the part of the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring can be reduced, and the Chinese medicine remaining on the part of the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring can be further reduced, and the pollution marks formed on the wall of the medicine barrel 1 can be further reduced, which can save more effort when cleaning the medicine barrel 1 later.

[0048] In this embodiment, the water adding part includes a water tank 9, a supporting part and a first water pipe 10, the supporting part is used to support the water tank 9 above the medicine barrel 1, the lower end of the first water pipe 10 is fixedly connected to the wiping ring and connected to the annular groove 8, the upper end of the first water pipe 10 is fixedly connected to the bottom of the water tank 9 and connected to the inner cavity of the water tank 9, and the first water pipe 10 is a silicone tube;

[0049] The drainage part includes a second water pipe 11, the lower end of which is fixedly connected to the wiping ring and connected to the annular groove 8, the upper end of which passes through the upper end of the medicine barrel 1 and extends laterally to the outside of the medicine barrel 1, the upper end of which is fixedly connected to the water tank 9, the second water pipe 11 is a silicone tube, and the upper end of which is lower than the upper end of the first water pipe 10.

[0050] Since the upper end of the second water pipe 11 is lower than the upper end of the first water pipe 10, when water is added to the receiving tank, the water in the receiving tank can enter the second water pipe 11 through the first water pipe 10 and the annular groove 8 in sequence, and then be discharged from the upper end of the second water pipe 11. With this structure, the water adding part can add water to the annular groove 8, and the water discharging part can discharge the water in the annular groove 8. It is convenient to add water to the annular groove 8 and to discharge the water in the annular groove 8.

[0051] Since the first water pipe 10 is a silicone tube and the second water pipe 11 is a silicone tube, and the silicone material is soft and elastic, the first water pipe 10 and the second water pipe 11 are both elastic hoses, and the first water pipe 10 and the second water pipe 11 can be stretched and straightened in the vertical direction during the wiping ring descending with the buoyancy ring 6, and can be bent and deformed during the wiping ring and the buoyancy ring 6 moving upward. The first water pipe 10 and the second water pipe 11 will not prevent the wiping ring from rising and falling.

[0052] In this embodiment, the water tank 9 is annular, and the upper end of the water tank 9 is open;

[0053] It also includes a condensation hood 12 fixedly connected to the water tank 9 and located directly above the medicine barrel 1. The condensation hood 12 is made of metal material, and the condensation hood 12 can be made of stainless steel material. The condensation hood 12 is in the shape of a hemispherical shell with an opening facing downward, and the lower end edge of the inner surface of the condensation hood 12 is located directly above the notch of the water tank 9.

[0054] During the evaporation and concentration of traditional Chinese medicine, the water vapor rising from the medicine barrel 1 can condense and liquefy into water droplets on the inner surface of the condensation cover 12. Since the condensation cover 12 is in the shape of a hemispherical shell with an opening facing downward, the lower edge of the inner surface of the condensation cover 12 is located directly above the notch of the water tank 9. The water droplets on the inner surface of the condensation cover 12 can flow downward along the inner surface of the condensation cover 12 and enter the water tank 9, which can automatically add water to the water tank 9, making it more convenient to add water to the water tank 9, that is, it is more convenient to add water to the annular groove 8 and to drain the water in the annular groove 8. The water entering the annular groove 8 can also be distilled water, which has almost no other impurities, and can reduce impurities such as scale condensed on the barrel wall of the medicine barrel 1, which is more labor-saving when cleaning the medicine barrel 1 later.

[0055] In this embodiment, the support part is a structure that can be retracted vertically. The support part can be extended so that the upper end of the support part moves upward, and the upper end of the support part drives the water tank 9 and the condensation cover 12 to move upward, and then moves the buoyancy ring 6 and the wiping ring upward. When the distance between the buoyancy ring 6 and the heating part 2 is greater than the height of the medicine barrel 1, the buoyancy ring 6 and the wiping ring are stopped from moving upward. At this time, it is convenient to place the medicine barrel 1 on the heating part 2, and it is also convenient to remove the medicine barrel 1 from the heating part 2.

[0056] In this embodiment, the support part includes a bottom plate 13, two square tubes 14, two moving rods 15 and two bolts 16. The lower ends of the two square tubes 14 are fixed on the bottom plate 13. The upper end walls of the two square tubes 14 are formed with screw holes. The two moving rods 15 are slidably fitted in the two square tubes 14. The upper ends of the moving rods 15 are located above the square tubes 14. The two bolts 16 are respectively screwed into the two screw holes. The screwed ends of the two bolts 16 are used to support the two moving rods 15 one by one. The heating part 2 is supported on the bottom plate 13. The heating part 2 and the medicine barrel 1 are located between the two square tubes 14. The water tank 9 is located between the two moving rods 15. The water tank 9 is fixedly connected to the upper ends of the two moving rods 15. With this structure, the support part can support the water tank 9 above the medicine barrel 1.

[0057] The two bolts 16 are rotated one by one in the two screw holes so that the two bolts 16 respectively support and tighten the two moving rods 15. At this time, the two moving rods 15 are fixed one by one in the two square tubes 14. The moving rods 15 cannot move up and down in the square tubes 14, and the support part cannot be extended and retracted vertically.

[0058] The two bolts 16 are rotated in the two screw holes one by one, so that the two bolts 16 are disengaged from the two moving rods 15 one by one, and the moving rods 15 can move up and down in the square tube 14, and the support part can be extended and retracted vertically. With this structure, the support part is a structure that can be extended and retracted vertically.

[0059] In this embodiment, a plurality of bristles 17 are fixedly disposed on the bottom wall of the annular groove 8, where the bottom wall of the annular groove 8 refers to the wall of the annular groove 8 facing the notch of the annular groove 8. The bristles 17 are arranged along the radial direction of the wiping ring, and the outer ends of the bristles 17 abut against the barrel wall of the medicine barrel 1.

[0060] In the process that the wiping ring and the buoyancy ring 6 oscillate up and down in the boiling and tumbling medicine liquid, the bristles 17 can move up and down, and the bristles 17 and the water in the annular groove 8 can jointly brush the barrel wall of the medicine barrel 1. In the process that the wiping ring moves downward, the traditional Chinese medicine remaining on the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring can be further reduced, and the traces of pollution formed on the wall of the medicine barrel 1 can be further reduced, which can save more effort in the subsequent cleaning of the medicine barrel 1.

[0061] In this embodiment, the wiping ring includes a first circular ring 18, a second circular ring 19, a connecting column 20, a silicone ring 21 and a fixing block 22. The first circular ring 18 and the second circular ring 19 are both matched with the inner cavity of the medicine barrel 1. The outer circumferential surface of the first circular ring 18 and the outer circumferential surface of the second circular ring 19 are both against the inner circumferential surface of the medicine barrel 1. The upper and lower ends of the connecting column 20 are respectively fixedly connected to the first circular ring 18 and the second circular ring 19. The silicone ring 21 is coaxially arranged with the first circular ring 18, and the upper end of the silicone ring 21 is fixed to the edge of the ring hole of the first circular ring 18. The lower end of the silicone ring 21 is fixedly connected to the edge of the ring hole of the second circular ring 19, and a plurality of through holes are evenly arranged on the silicone ring 21 along the circumferential direction. There are multiple fixed blocks 22, and the multiple fixed blocks 22 are fixed in the multiple through holes one by one and block the multiple through holes; a plurality of bristles 17 are fixed on the side of each fixed block 22 facing the barrel wall of the medicine barrel 1; it also includes a buoyancy block 23 and a plurality of rod bodies 24, the outer ends of the plurality of rod bodies 24 are fixedly connected to the plurality of fixed blocks 22 one by one, and the inner ends of the plurality of rod bodies 24 are hinged to the buoyancy block 23.

[0062] The silicone ring 21 is made of silicone material, which is soft and elastic, so that the fixed block 22 can move on the silicone ring 21. During the evaporation and concentration of traditional Chinese medicine, the buoyancy block 23 floats on the surface of the traditional Chinese medicine liquid. When the traditional Chinese medicine liquid boils and rolls, the buoyancy block 23 can move up and down relative to the buoyancy ring 6. The buoyancy block 23 can drive the inner end of the rod body 24 to swing up and down, so that the outer end of the brush 17 can also swing up and down. In addition to being able to brush the barrel wall of the medicine barrel 1 by moving up and down, the bristles 17 can also brush the barrel wall of the medicine barrel 1 by swinging, which can improve the brushing effect of the barrel wall of the medicine barrel 1, and can further reduce the traditional Chinese medicine remaining on the barrel wall of the medicine barrel 1 located on the upper side of the wiping ring, and can reduce the pollution marks formed on the wall of the medicine barrel 1, which is more labor-saving when cleaning the medicine barrel 1 later.

[0063] In this embodiment, the buoyancy block 23 is made of metal material and has a hollow cylindrical structure so that the overall average density of the buoyancy block 23 is less than the density of water, so that the buoyancy block 23 can float on the liquid surface of the traditional Chinese medicine.

[0064] In this embodiment, the outer circumference of the first circular ring 18 is recessed inward to form a first circular sealing groove, a first sealing ring 25 is arranged in the first sealing groove, and the first sealing ring 25 is interference fit with the first sealing groove; the outer circumference of the second circular ring 19 is recessed inward to form a second circular sealing groove, a second sealing ring 26 is arranged in the second sealing groove, and the second sealing ring 26 is interference fit with the second sealing groove. The first sealing ring 25 can seal the gap between the first circular ring 18 and the barrel wall of the medicine barrel 1, and the second sealing ring 26 can seal the gap between the second circular ring 19 and the barrel wall of the medicine barrel 1, which can reduce the possibility of water in the annular groove 8 leaking from the gap between the first circular ring 18 and the barrel wall of the medicine barrel 1 and the gap between the second circular ring 19 and the barrel wall of the medicine barrel 1.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
