DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] 1 to 10 , the present invention provides: an extraction and purification device, comprising a bottom tank 1, an extraction tower 2, an extraction mixing assembly 4 and a product cooling assembly 10. The bottom tank 1 is the main part of the device, and is usually used to store raw materials or solvents to be extracted. The bottom tank 1 needs to have sufficient capacity and strength to withstand the pressure and temperature fluctuations that may occur during the extraction process. An extraction tower 2 is arranged on the top of the bottom tank 1, and a product cooling assembly 10 is connected to one side of the top of the extraction tower 2. The product cooling assembly 10 is used to cool the product, and the product cooling assembly 10 also liquefies the gaseous product into liquid. The product cooling assembly 10 includes a cooling tank 1002 and a cooling mechanism 102. The cooling tank 1002 is the main part of the cooling assembly and is used to accommodate a cooling medium. A top plate 1004 is arranged in the cooling tank 1002, and a shunt pipe 1005 is connected to the bottom of the top plate 1004, and a bottom plate 1006 is connected to the bottom of the shunt pipe 1005. A first pipe 1001 is connected to the top of the top plate 1004, and one end of the first pipe 1001 passes through the cooling tank 1002 and is connected to the top of the extraction tower 2. The top plate 1004 and the bottom plate 1006 together with the shunt pipe 1005 form a distribution system for evenly distributing the gaseous product in the cooling tank 1002. In order to improve the cooling efficiency.

[0034] In this embodiment, the product is evaporated into gaseous state, and the gaseous product enters into the shunt pipe 1005. The special structure in the shunt pipe 1005 increases the heat conduction area, so that the gaseous product is cooled into liquid, thereby increasing the purity of the product and improving the purification efficiency.

[0035] The top plate 1004 is hollow inside, and the diverter pipe 1005 is vertically inserted into the bottom of the top plate 1004. The top plate 1004 is the initial contact point for the product to enter the cooling tank 1002, and plays a role in preliminary cooling and dispersion of the product. There are several diverter pipes 1005 evenly arranged between the top plate 1004 and the bottom plate 1006, and each diverter pipe 1005 is also provided with several annular protrusions on the outside. The diverter pipe 1005 is used to divert the product flowing into the top plate 1004. The diverter pipe 1005 increases the contact area with the heat transfer agent in the external cooling tank 1002 to quickly cool the product. These protrusions not only increase the contact area between the diverter pipe 1005 and the heat transfer agent in the cooling tank 1002, but also accelerate the cooling process of the product by increasing the contact area with the heat transfer agent.

[0036] In this embodiment, the high-temperature product enters the top plate 1004 through the first pipe 1001 and flows into the diverter pipe 1005. The diverter pipe 1005 evenly diverts the product to different areas of the cooling tank 1002 and increases the contact area with the heat transfer agent through the annular protrusion on its outside, thereby accelerating the cooling process of the product.

[0037] The cooling tank 1002 is hollow inside and filled with a heat conductor. The top plate 1004, the shunt pipe 1005 and the bottom plate 1006 are inserted into the cooling tank 1002. The bottom of the bottom plate 1006 is connected with a second pipe 1003, and the second pipe 1003 passes through the cooling tank 1002 and extends out.

[0038] The product cooling assembly 10 also includes a cooling mechanism 102, which includes a protective shell 1021, and the protective shell 1021 is arranged outside the bottom tank 1, and the protective shell 1021 is used to protect the cooling mechanism 102 from being directly affected by the external environment, while improving the cooling efficiency. A cooler 1024 is installed inside the protective shell 1021; the cooler 1024 includes a heat conductive sheet 10241 and a heat conductive pipe 10242, and the heat conductive sheet 10241 is formed by stacking a number of metal sheets to increase the heat conduction area. The design of the heat conductive sheet 10241 can significantly increase the contact area with the cooling medium (such as cooling water or refrigerant), thereby improving the heat conduction efficiency. The main function of the heat conductive sheet 10241 is to conduct the heat emitted from the gaseous product to the liquid product, and quickly disperse it to a larger area, so as to more effectively exchange heat with the cooling medium. A plurality of heat conducting pipes 10242 are coiled between the heat conducting sheets 10241, and the heat conducting pipes 10242 are made of metal pipes, and the heat conducting pipes 10242 are arranged in a "snake" shape in the heat conducting sheets 10241 to increase the heat conducting area. The design of the heat conducting pipes 10242 further increases the contact area with the heat conducting sheets 10241, thereby improving the heat conduction efficiency. At the same time, the "snake" shape arrangement is also conducive to increasing the flow path of the fluid in the pipe, thereby improving the heat exchange efficiency.

[0039] In this embodiment, the heat conductor circulates in the cooler 1024 in the protective shell 1021. When the heat emitted by the gaseous product converted into a liquid product is conducted to the cooler 1024, the heat conductive sheet 10241 quickly disperses the heat to a larger area and exchanges heat with the heat pipe 10242. Due to the special design of the heat conductive sheet 10241 and the heat pipe 10242 (such as the stacked metal sheets and the "snake"-shaped arrangement of the heat pipe 10242), the heat conduction and heat exchange efficiency are significantly improved, thereby achieving rapid cooling of the product.

[0040] The cooling mechanism 102 further includes a pump body 1025, which is a key component in the cooling mechanism 102 and is responsible for driving the heat transfer agent in the cooling tank 1002 to flow. One end of the pump body 1025 is fixedly connected to the heat transfer pipe 10242 through a pipeline, and one end of the heat transfer pipe 10242 is connected to the second circulation pipe 1023, one end of the second circulation pipe 1023 extends to the upper part of the cooling tank 1002 and extends into the cooling tank 1002, the other end of the pump body 1025 is connected to the first circulation pipe 1022, and one end of the first circulation pipe 1022 passes through the protective shell 1021 and is connected to the lower part of the cooling tank 1002 and extends into the cooling tank 1002. The pump body 1025 is used for the heat transfer agent in the cooling tank 1002 to flow, and the heat transfer agent flows into the heat transfer pipe 10242 to introduce heat to the heat conductive sheet 10241.

[0041] In this embodiment, by starting the pump body 1025, the internal heat conductor is driven to flow. The heat conductor is driven by the pump body 1025, flows through the heat pipe 10242, and exchanges heat with the heat conductive sheet 10241. The cooled heat conductor enters the pump body 1025 again through the first circulation pipe 1022 to form a complete circulation loop.

[0042] The protective shell 1021 has a plurality of heat dissipation slots for heat dissipation on its exterior. At least one heat dissipation fan 1026 is also fixed on the exterior of the protective shell 1021 . The heat dissipation fan 1026 is used to circulate air in the protective shell 1021 and remove heat from the heat conducting sheet 10241 .

[0043] In this embodiment, when the heat dissipation fan 1026 is started, it will inhale external air through the heat dissipation slots. The air will blow through the heat conductive sheet 10241 and the heat conductive pipe 10242. In this way, the heat will be taken away from the protective shell 1021, thereby cooling the internal heat conductive agent.

[0044] The bottom tank 1 is used to store the liquid to be extracted, the extraction tower 2 is used to extract the liquid, and an extraction mixing component 4 is arranged in the extraction tower 2; the extraction mixing component 4 includes a rotating driving member 401 and a rotating rod 402, the rotating driving member 401 is fixed on the top of the extraction tower 2, the rotating rod 402 is vertically rotated and arranged in the extraction tower 2, and one end of the rotating rod 402 extends into the bottom tank 1 and is fixed with a stirring blade 406 for stirring the liquid in the bottom tank 1, the other end of the rotating rod 402 passes through the top of the extraction tower 2 and is fixedly connected to the output end of the rotating driving member 401, and the rotating driving member 401 rotates to drive the rotating rod 402 to rotate and simultaneously drives the stirring blade 406 to rotate.

[0045] In this embodiment, the rotary drive member 401 starts to work, and the rotary drive member 401 drives the rotary rod 402, and the entire rotary rod 402 starts to rotate. As the rotary rod 402 rotates, the stirring blade 406 also starts to rotate, thereby stirring the liquid in the bottom tank 1. This stirring action helps to evenly mix the liquid, making the extraction process more effective.

[0046] The extraction mixing assembly 4 includes a fixed ring 403, a rotating disk 404 and blades 405, and the rotating disk 404 is evenly distributed on the rotating rod 402, and the blades 405 are also evenly distributed on the rotating rod 402, and the fixed ring 403 is evenly fixed on the inner wall of the extraction tower 2, the rotating disk 404 is arranged between the two fixed rings 403, and the blades 405 and the fixed ring 403 are in the same plane.

[0047] In this embodiment, when the rotary drive member 401 starts to work, it drives the rotary rod 402 to rotate. As the rotary rod 402 rotates, the turntable 404 and the blade 405 also rotate together. In this process, the turntable 404 and the blade 405 generate shear force and turbulence through the contact of their surfaces with the liquid during rotation, which promotes the mixing and extraction of the liquid. The components in the mixture will fully contact and form different solubilities, which is conducive to separation. As the turntable 404 rotates, the mixture will be brought to the top of the tower body and then gradually flow downward. In this process, due to the difference in solubility of each component in different solvents, they will gradually separate out, thereby achieving separation of the mixture.

[0048] The interlayer inside the extraction tower 2 is equipped with several heating coils 11, and the heating coils 11 use the electromagnetic induction principle to heat the internal metal components. The heating coils 11 use the electromagnetic induction principle to heat the internal metal components through the action of the electromagnetic field. This heating method has the characteristics of high efficiency, rapidity, and contactlessness, and can quickly transfer heat to the liquid inside the extraction tower 2 to maintain or adjust the temperature of the liquid. Then, the heat is transferred to the liquid inside the extraction tower 2. The bottom tank 1 and the extraction tower 2 are also provided with temperature sensors for detecting the temperature of the liquid; the bottom tank 1 and the extraction tower 2 are externally equipped with a liquid inlet 6, and the liquid inlet 6 is connected to the first electromagnetic valve 5. The bottom tank 1 is also externally equipped with a heavy liquid outlet 8, and the heavy liquid outlet 8 is connected to the second electromagnetic valve 7. The bottom tank 1 and the extraction tower 2 are also externally equipped with an inspection platform 3 for staff to inspect. The inspection platform 3 provides a safe and convenient inspection and maintenance space for the staff. The staff can inspect, repair and replace the bottom tank 1, extraction tower 2 and related components on the inspection platform 3. A safety valve 9 is also provided on the top of the extraction tower 2 to protect the extraction tower 2 from damage under overpressure or other abnormal conditions. When the pressure inside the extraction tower 2 exceeds the set safety value, the safety valve 9 will automatically open to release the internal pressure to prevent the extraction tower 2 from explosion or leakage.

[0049] Working principle: When in use, the liquid inlet pipe is connected to the two first solenoid valves 5, the liquid outlet pipe is connected to the second solenoid valve 7 and the second pipeline 1003, and then connected to other equipment, and then the liquid is passed into the bottom tank 1 and the extraction tower 2. At this time, by starting the rotating drive member 401, the rotating drive member 401 rotates the rotating rod 402, and the rotating rod 402 rotates the turntable 404 and the blade 405. In this process, the components in the mixture will fully contact and form different solubilities, which is conducive to separation. As the turntable 404 rotates, the mixture will be brought to the top of the tower body and then gradually flow downward. In this process, due to the difference in solubility of each component in different solvents, they will gradually separate out, thereby achieving separation of the mixture. In order to make the product purer, the product in the extraction tower 2 is heated to make the temperature in the product reach the evaporation temperature of the product, and then the product evaporates and enters the top plate 1004 from the first pipeline 1001, and then the product enters the branch pipe 1005. A plurality of branch pipes 1005 are used to increase the contact area with the heat conductor, so that the gas is cooled into liquid. By starting the pump body 1025, the pump body 1025 makes the heat conductor in the cooling tank 1002 flow, and the heat conductor flows into the heat pipe 10242. Since the heat pipe 10242 is provided with a heat conducting sheet 10241 on the outside, heat is introduced into the heat conducting sheet 10241. By starting the cooling fan 1026, the cooling fan 1026 makes the air flow, so that the heat conductor is cooled, and the liquefied product is discharged from the second pipeline 1003. The extractant and other impurities flow out from the heavy liquid outlet 8 and the second solenoid valve 7 to another device for processing, thereby completing the purification.

[0050] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
