DETAILED DESCRIPTION
[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0027] First embodiment:
[0028] refer to Figure 1 and Figure 2, an air heating pipe 1, comprising a pipe body 10, a heating element 11 and a heat conducting element 12;
[0029] The heating element 11 and the heat conducting element 12 are both arranged inside the tube body 10, and the heat conducting element 12 is in contact with the heating element 11;
[0030] The heat conducting member 12 is extended along the length direction of the tube body 10 , and the material of the heat conducting member 12 is graphene.
[0031] The heating element 11 is used to generate heat, and the heat-conducting element 12 is used to conduct heat. When air or other gases flow through the tube body 10, they successively contact the heating element 11 and the heat-conducting element 12 and are gradually heated. Among them, the length of the heating element 11 and the heat-conducting element 12 after assembly is basically equal to or slightly smaller than the length of the tube body 10.
[0032] Graphene has a higher thermal conductivity than copper and aluminum. Selecting graphene to make the heat conducting member 12 is beneficial to improving the heat conducting effect, thereby improving the efficiency of air heating.
[0033] The heat-conducting member 12 is tubular and can be sleeved on the heating element 11 , thereby increasing the contact area between the air and the heating element 11 and the heat-conducting member 12 , thereby increasing the temperature of the air intake end.
[0034] The heating element 11 is a heat generating semiconductor.
[0035] The heating element 11 is disposed at the air inlet end 10 a of the tube body 10 , and the heat conducting element 12 is extended from the air inlet end 10 a to the air outlet end 10 b of the tube body 10 .
[0036] The air inlet end 10a is provided with a nut body 13, and the air outlet end 10b is provided with a regulating valve 14. Both the nut body 13 and the regulating valve 14 can be connected to the pipe body 10 through a threaded structure, and the nut body 13 can limit the position of the heating element 11 to a certain extent, that is, prevent the heating element 11 from falling out of the pipe body 10. The regulating valve 14 can adjust the opening of the air outlet end 10b of the pipe body 10, thereby adjusting the flow rate of the gas.
[0037] A rubber ring 16 and a gasket 15 are arranged between the nut body 13 and the tube body 10. The arrangement of the rubber ring 16 and the gasket 15 further prevents the heating element 11 from falling out of the tube body 10, and also makes the connection between the nut body 13 and the tube body 10 less likely to loosen and more stable. In addition, the rubber ring 16 and the gasket 15 can protect the electronic wire of the heating element 11 and reduce the electronic wire from being scratched.
[0038] Second embodiment:
[0039] refer to Figures 3 to 5 A high-efficiency concentration tank 2 is used to concentrate the boiled Chinese medicine, that is, to evaporate the water of the Chinese medicine, increase the concentration of the liquid medicine, and even concentrate the liquid medicine to the state of ointment. It can be used in hospitals, pharmacies and other places.
[0040] The concentration tank 2 includes the air heating tube 1 of the first embodiment described above;
[0041] The concentrating tank 2 is provided with an air inlet 23 and an air outlet 24. The air inlet 23 can be provided on the upper surface of one end of the concentrating tank 2, and the air outlet 24 can be provided on the upper surface of the other end of the concentrating tank 2.
[0042] The air inlet 23 is connected to the air heating pipe 1, for example, the end of the regulating valve 14 away from the pipe body 10 is connected to the air inlet 23 through a threaded structure;
[0043] The air outlet 24 is connected to the negative pressure generator 4, which is a fan.
[0044] The negative pressure generator 4 can cause negative pressure and airflow to be formed inside the concentration tank 2; when the negative pressure generator 4 is working, it draws air outward, and negative pressure is formed inside the concentration tank 2, causing gas to flow into the concentration tank 2 from the air inlet 23, and the gas inside the concentration tank 2 flows out from the air outlet 24 to form an airflow. It can be seen that the negative pressure generator 4 not only causes negative pressure to be formed in the concentration tank 2, but also causes a flowing airflow to be formed inside the concentration tank 2;
[0045] Due to the action of the negative pressure generator 4, negative pressure is formed inside the concentration tank 2, and the boiling temperature of the liquid medicine is reduced. In this way, the liquid medicine boils under a relatively low temperature and negative pressure environment, making it difficult for unstable effective ingredients of traditional Chinese medicine to volatilize, oxidize and pyrolyze, and not pollute the environment. The effective ingredients of traditional Chinese medicine are dissolved quickly, but the boiling temperature is reduced, and the saturation of the steam is reduced, which affects the concentration efficiency. At this time, under the action of the negative pressure generator 4, a certain airflow is formed inside the concentration tank 2, which accelerates the flow of steam, so that the steam can be discharged from the concentration tank 2 in time. At the same time, after the steam is discharged in time, the steam seal in the tank is reduced, which can promote the water to become steam faster, and the relatively orderly flow of the airflow is conducive to promoting the orderly flow and discharge of steam, which is conducive to improving the concentration efficiency. Therefore, compared with the existing concentration tank with a sealed structure, the open concentration tank 2 formed by the present application with airflow is more conducive to increasing the evaporation rate, thereby improving the concentration efficiency, and negative pressure concentration is also conducive to energy saving.
[0046] The negative pressure generator 4 is a fan, which can be appropriately adjusted in power, gear, etc. according to different working conditions to form different negative pressure values. The selection of the fan is conducive to control and adjustment. In addition, compared with the negative pressure machine, the fan consumes less power and is more conducive to energy saving.
[0047] In order to improve or ensure the efficiency of concentration, an air heating pipe 1 is provided at the air inlet 23 to heat or preheat the air flowing into the concentration tank 2, thereby reducing the temperature difference between the incoming air and the air in the tank. In this way, the temperature difference is relatively reduced, the amount of heat to be absorbed is reduced, the impact on the temperature inside the concentration tank 2 is reduced, the temperature fluctuation is reduced, and the concentration tank 2 can operate under a relatively stable working condition, thereby improving or ensuring the concentration efficiency.
[0048] The bottom of the inner cavity of the concentration tank 2 is provided with an electric heating rod 3. There may be multiple electric heating rods 3, for example, three electric heating rods 3 are provided, and the electric heating rod 3 is used to heat the liquid medicine. The electric heating rod 3 is arranged inside the concentration tank 2, and the heat utilization rate is higher and the heating efficiency is higher.
[0049] The concentration tank 2 includes a first tank body 2a and a second tank body 2b which are interconnected; the second tank body 2b is arranged below the first tank body 2a, and the second tank body 2b is arranged to be gradually narrowed downward. It can also be understood that the cross-sectional shape of the concentration tank 2 is irregular, and is composed of two parts, wherein the cross-sectional shape of the first tank body 2a can be a rectangle, and the cross-sectional shape of the second tank body 2b can be an inverted trapezoid;
[0050] A round tube 25 is provided at the bottom of the second tank body 2 b , and an electric heating rod 3 is provided inside the round tube 25 , that is, the electric heating rod 3 is inserted into the round tube 25 .
[0051] The cross-sectional shape of the second tank body 2b gradually narrows downward, causing the liquid surface area to gradually decrease as the concentration of the liquid approaches the completion stage, and the liquid gradually gathers or approaches the electric heating rod 3, thereby accelerating the concentration efficiency and better concentrating to a preset concentration or capacity.
[0052] The concentration tank 2 is also provided with a liquid inlet 21 and a liquid outlet 22 . The liquid medicine flows into the concentration tank 2 through the liquid inlet 21 , and flows out from the liquid outlet 22 after completing the negative pressure concentration.
[0053] The above disclosure is only some embodiments of the utility model. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the utility model, and these all belong to the protection scope of the utility model.
