Abstract
Description
Technical Field
[0001] This utility model belongs to the field of extraction equipment technology, specifically relating to a multifunctional extraction tank with heat reflux energy saving. Background Technology
[0002] In industries such as traditional Chinese medicine, food, chemicals, and biopharmaceuticals, extraction is a crucial step in obtaining target components. Traditional hot reflux extraction tanks have gradually revealed some significant problems over prolonged use, particularly regarding steam recycling and solvent temperature uniformity.
[0003] First, traditional hot reflux extraction tanks often employ direct discharge or simple condensation methods for steam treatment, resulting in a significant amount of thermal energy remaining unutilized. Directly releasing the large amount of thermal energy contained in the steam into the environment not only wastes energy but may also cause thermal pollution. Simple condensation, on the other hand, requires additional cooling equipment, increasing processing costs, and still fails to effectively utilize the thermal energy contained in the steam.
[0004] Secondly, traditional extraction tanks have shortcomings in solvent temperature control: the heating of the solvent inside the tank usually relies on the heat source in the jacket outside the tank, and the flow and mixing of the solvent inside the tank are often insufficient, resulting in significant differences in solvent temperature in different areas of the tank. This temperature inhomogeneity not only affects the extraction efficiency, but may also lead to unstable quality of the extracted product. Summary of the Invention
[0005] To address the above problems, the purpose of this utility model is to provide a multifunctional extraction tank with heat reflux and energy saving, which solves the problems that existing extraction tanks cannot effectively recover and utilize the large amount of heat energy contained in steam, and that the uneven temperature of the solvent inside the tank leads to unstable product quality.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional extraction tank for heat reflux energy saving, comprising a tank body, a baffle plate provided at the top of the tank body, a steam manifold formed between the baffle plate and the top of the tank body, a stirrer rotatably mounted on the tank body, multiple air inlets being provided through the baffle plate around the stirrer and connected to the top ends of multiple reflux heat exchange tubes, the bottom end of the reflux heat exchange tubes being connected to an annular manifold, the annular manifold being connected to one end of an exhaust pipe, the other end of the exhaust pipe being connected to a cooler through the bottom side of the tank body, and a feeding port provided at the top of the tank body.
[0007] The beneficial effects of this utility model are as follows: by setting up a steam manifold and a reflux heat exchange tube to circulate steam, energy consumption is significantly reduced and energy utilization is improved; by setting the reflux heat exchange tube on the periphery of the stirrer, the axially flowing solvent is made to contact the reflux heat exchange tube evenly, which helps to improve the uniformity of temperature inside the tank and ensure stable product quality.
[0008] To prevent the material fed into the feeding port from entering the steam manifold;
[0009] As a further improvement to the above technical solution: the partition plate has a through hole structure at the bottom end for connecting the feeding port.
[0010] The beneficial effects of this improvement are: the steam manifold and the feeding port are isolated from each other, which effectively prevents the material fed into the feeding port from entering the interior of the steam manifold.
[0011] In order to achieve uniform heating of the solvent inside the tank;
[0012] As a further improvement to the above technical solution: the number of reflux heat exchange tubes is multiple, and they are arranged at equal intervals around the axis of the tank and the agitator.
[0013] The beneficial effects of this improvement are: the multiple reflux heat exchange tubes arranged circumferentially around the outside of the stirrer can fully contact the water flow driven by the stirrer, thereby achieving uniform heating of the solvent in the tank.
[0014] To ensure that the solvent pushed by the stirrer makes uniform contact with the reflux heat exchange tube;
[0015] As a further improvement to the above technical solution: the axis of the reflux heat exchange tube is set parallel to the axis of the stirrer.
[0016] The beneficial effect of this improvement is that the axially flowing solvent pushed by the stirrer can flow along the surface of the reflux heat exchange tube and make uniform contact with the reflux heat exchange tube.
[0017] In order to make the solvent flow effectively along the axial direction of the reflux heat exchange tube by using a stirrer;
[0018] As a further improvement to the above technical solution: the agitator is a paddle agitator, and the diameter of the agitator is not greater than the inner diameter of the annular manifold.
[0019] The beneficial effect of this improvement is that the solvent is transported in the axial direction when the stirrer rotates, so that the solvent can fully contact the reflux heat exchange tube.
[0020] In order to effectively combine and recover the steam discharged from the reflux heat exchanger tubes;
[0021] As a further improvement to the above technical solution: the annular manifold has a circular pipe structure, and the axis of the annular manifold is collinear with the axis of the stirrer.
[0022] The beneficial effects of this improvement are: the annular manifold can effectively collect the steam and droplets flowing out of multiple reflux heat exchange tubes and discharge them to subsequent treatment equipment through the exhaust pipe.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0029] Example 1:
[0030] like Figure 1As shown in Figure 3: A multifunctional extraction tank for energy saving through heat reflux includes a tank body 1. A baffle 2 is provided on the inner top of the tank body 1. A steam manifold 9 is formed between the baffle 2 and the top of the tank body 1. A stirrer 5 is rotatably mounted on the tank body 1. Multiple air inlets 3 are provided through the baffle 2 around the stirrer 5 and are connected to the top ends of multiple reflux heat exchange tubes 4. The bottom end of the reflux heat exchange tubes 4 is connected to an annular manifold 7. The annular manifold 7 is connected to one end of an exhaust pipe 8, and the other end of the exhaust pipe 8 is connected to... A cooler is connected to the bottom of the tank body 1, and a feeding port 6 is provided at the top of the tank body 1. Steam is circulated through the steam manifold 9 and the reflux heat exchange pipe 4, significantly reducing energy consumption and improving energy efficiency. By placing the reflux heat exchange pipe 4 around the agitator 5, the axially flowing solvent is made to contact the reflux heat exchange pipe 4 evenly, which helps to improve the temperature uniformity inside the tank and ensure stable product quality. A through-hole structure is provided on the partition plate 2 to connect to the bottom end of the feeding port 6. The steam manifold 9 and the feeding port 6 are connected... The mutual isolation design effectively prevents the material fed into the feed port 6 from entering the steam manifold 9. Multiple reflux heat exchange tubes 4 are arranged at equal intervals around the axes of the tank 1 and the agitator 5. These multiple reflux heat exchange tubes 4, circumferentially surrounding the outside of the agitator 5, can fully contact the water flow pushed by the agitator 5, achieving uniform heating of the solvent inside the tank 1. The axes of the reflux heat exchange tubes 4 are parallel to the axis of the agitator 5, allowing the axially flowing solvent pushed by the agitator 5 to flow along the surface of the reflux heat exchange tubes 4. The solvent flows evenly and contacts the reflux heat exchange tube 4. The stirrer 5 is a paddle-type stirrer, and the diameter of the stirrer 5 is not greater than the inner diameter of the annular manifold 7. When the stirrer 5 rotates, it transports the solvent in the axial direction, so that the solvent can fully contact the reflux heat exchange tube 4. The annular manifold 7 is a circular pipe structure, and the axis of the annular manifold 7 is collinear with the axis of the stirrer 5. The annular manifold 7 can effectively collect the steam and droplets flowing out of multiple reflux heat exchange tubes 4 and discharge them to the subsequent processing equipment through the exhaust pipe 8.
[0031] The working principle of this technical solution is as follows: Raw materials are fed into the interior of tank 1 through feeding port 6, and then a cover plate is bolted to feeding port 6. Subsequently, tank 1 is heated using existing technology, and at the same time, the motor connected to agitator 5 is turned on, driving agitator 5 to rotate and stir the material solvent in tank 1. As the temperature of the solvent in tank 1 rises, the evaporation rate of the solvent accelerates, and the generated vapors and volatiles flow upward, enter the steam manifold 9 through air inlet 3, and then flow downward through reflux heat exchange pipe 4 into annular manifold 7, and then are discharged through exhaust pipe 8 to subsequent cooling devices and other mechanisms. During the flow of steam in reflux heat exchange pipe 4 and annular manifold 7, the surface of reflux heat exchange pipe 4 and annular manifold 7 is heated, thereby heating the solvent in contact with reflux heat exchange pipe 4 and annular manifold 7, realizing the utilization of steam heat. The axial flow generated by agitator 5 can flow from bottom to top along the surface of reflux heat exchange pipe 4, fully contacting reflux heat exchange pipe 4, and uniformly increasing the temperature of the solvent in tank 1 in conjunction with the setting of external jacket.
