[0020] Embodiment 1:

[0021] Referring to Figures 1 to 5 , the present invention provides an artemisia essential oil concentration device, which includes a concentration tank 1, a raw material tank 2 and a pump body 3. The upper end of the concentration tank 1 is communicated with a liquid inlet pipe 11 and a steam pipe 12, the lower end of the concentration tank 1 is communicated with a liquid outlet pipe 13, a heating mechanism 4 is arranged at the bottom of the concentration tank 1, the bottom of the raw material tank 2 is communicated with a feeding pipe 21, a plurality of shunt pipes 22 are communicated on the feeding pipe 21, the plurality of shunt pipes 22 are communicated with the liquid inlet pipe 11, the pump body 3 is arranged on the feeding pipe 21, a first heat exchange tank 5 is sleeved at the plurality of shunt pipes 22, the steam pipe 12 is communicated with the first heat exchange tank 5, a first heat exchange component 6 and an exhaust pipe 51 are arranged at the first heat exchange tank 5, a second heat exchange tank 7 is sleeved at the feeding pipe 21, the liquid outlet pipe 13 is communicated with the second heat exchange tank 7, a second heat exchange component 8 and a blanking pipe 71 are arranged on the second heat exchange tank 7, and valves are arranged on both the liquid outlet pipe 13 and the steam pipe 12.

[0022] The pump body 3 extracts the raw materials in the raw material tank 2 into the concentration tank 1 through the feeding pipe 21, several shunt pipes 22 and the liquid inlet pipe 11 for concentration work by the heating mechanism 4. The steam generated during the concentration process is discharged through the steam pipe 12, the first heat exchange box 5 and the exhaust pipe 51, and during this process, the raw materials in the shunt pipes 22 are preheated by the first heat exchange component 6. The concentrated liquid with a higher temperature after concentration is discharged through the liquid outlet pipe 13, the second heat exchange box 7 and the blanking pipe 71, and during this process, the raw materials at the feeding pipe 21 are preheated by the second heat exchange component 8, that is, the full utilization of heat energy is realized, with a good preheating effect, reducing the heating time of the concentration work and improving the overall concentration efficiency. Among them, the valves at the liquid outlet pipe 13 and the steam pipe 12 can be adjusted according to needs to control the flow rate of the concentrated liquid in the liquid outlet pipe 13 and the steam flow rate at the steam pipe 12, so as to adjust the heat exchange process at the first heat exchange box 5 and the second heat exchange box 7 and realize the adjustment of the heat exchange efficiency.

[0023] Specifically, the first heat exchange component 6 includes several first sleeves 61 and several heat conducting fins 62. Each shunt pipe 22 is sleeved with a first sleeve 61, and several heat conducting fins 62 arranged in an array along its axial direction are provided on each first sleeve 61. During the process that the steam at the steam pipe 12 passes through the first heat exchange box 5 and is discharged by the exhaust pipe 51, the steam exchanges heat with several heat conducting fins 62 and preheats each shunt pipe 22 through several first sleeves 61. The structural settings of the heat conducting fins 62 and the shunt pipes 22 greatly increase the heat exchange area, improve the overall heat exchange efficiency and play a good energy-saving role.

[0024] Specifically, the second heat exchange component 8 includes a second sleeve 81 and a spiral blade 82. The second sleeve 81 is sleeved on the outer wall of the feeding pipe 21. The second heat exchange box 7 has a cylindrical structure. The inner and outer sides of the spiral blade 82 are respectively connected to the outer wall of the second sleeve 81 and the inner wall of the second heat exchange box 7 to form a spiral channel 9 for liquid circulation. The blanking pipe 71 is communicated with the spiral channel 9.

[0025] During the process that the concentrated liquid is discharged through the spiral channel 9 and the blanking pipe 71 by the liquid outlet pipe 13, the concentrated liquid preheats the raw materials in the feeding pipe 21 through the second sleeve 81. The use of the spiral channel 9 structure increases the flow distance of the concentrated liquid relative to the feeding pipe 21, thereby improving its heat exchange effect, further preheating the raw materials and playing a good energy-saving role.

[0026] Embodiment 2:

[0027] Refer to Figures 1 to 5 Combined with the technical solution of Embodiment 1, in this embodiment, a one-way valve 23 is provided at the feeding pipe 21, and a pressure valve 14 is provided at the connection between the liquid inlet pipe 11 and the concentration tank 1.

[0028] Specifically, a stirring rod 15 driven by a motor is provided on the concentration tank 1. The motor drives the stirring rod 15 to rotate to continuously turn over the raw materials in the concentration tank 1, enabling the raw materials to come into full contact with the heating mechanism 4 at the bottom. While improving the heat exchange efficiency, it can also continuously agitate the raw materials, effectively preventing the raw materials from adhering to the inner wall of the concentration tank 1.

[0029] Specifically, the heating mechanism 4 includes an electric heating tube 41 and a heat conducting plate 42. The heat conducting plate 42 is arranged at the bottom of the concentration tank 1, and the electric heating tube 41 is closely attached to the heat conducting plate 42 and used to heat the heat conducting plate 42.

[0030] Working principle: Each time the concentration operation is carried out, the pump body 3 extracts the raw materials in the raw material tank 2 into the concentration tank 1 through the feeding pipe 21, several shunt pipes 22 and the liquid inlet pipe 11 for concentration work by the heating mechanism 4. After adding a certain amount of raw materials to the concentration tank 1 each time, the pump body 3 can be stopped. At this time, the heating mechanism 4 continuously heats the raw materials in the concentration tank 1 and generates steam. Due to the action of the one-way valve 23 and the pressure valve 14, part of the raw materials are intercepted in the feeding pipe 21, several shunt pipes 22 and the liquid inlet pipe 11, which is convenient for preheating this part of the raw materials more fully through the steam pipe 12, the first heat exchange box 5, the first heat exchange component 6, the liquid outlet pipe 13, the second heat exchange box 7 and the second heat exchange component 8, making relatively sufficient preheating preparations for the next concentration work and saving energy consumption. After the pump body 3 is started, the hydraulic pressure provided by the pump body 3 will reopen the pressure valve 14, facilitating the control of the feeding process of the raw materials into the concentration tank 1.

[0031] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, all changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention fall within the protection scope of this technical solution.
