[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] Please see Figures 1-4 The present invention provides the following technical solution: an extraction device for silicone oil production, comprising an outer cylinder 1, and further comprising: a top cover 2, a heating component 3, a first electric push rod 4, an extraction cylinder 5, a stirring mechanism 6, a driving mechanism 7, and an exhaust one-way valve 10.

[0051] Furthermore, by Figure 1As shown, in this embodiment, the top cover 2 is hinged to the top of the outer cylinder 1, the heating component 3 is fixed on the top cover 2 and used to deliver hot air into the outer cylinder 1, the first electric push rod 4 is hinged to the outer wall of the outer cylinder 1 and the piston rod of the first electric push rod 4 is hinged to the top cover 2, the extraction cylinder 5 is detachably installed in the outer cylinder 1, the stirring mechanism 6 is rotatably installed in the extraction cylinder 5, the driving mechanism 7 is used to drive the stirring mechanism 6 to rotate, and the exhaust one-way valve 10 is fixed to the bottom of the outer side of the outer cylinder 1. With the above scheme, in use, the top cover 2 is first driven to rotate around the hinge point by controlling the extension and retraction of the piston rod of the first electric push rod 4, so as to realize the opening and closing of the top cover 2.

[0052] When it is necessary to add raw materials or replace the extraction cylinder 5, the piston rod retracts, causing the top cover 2 to flip upward, exposing the internal space of the outer cylinder 1. The operator can then install the extraction cylinder 5 containing the reactants into the designated position inside the outer cylinder 1.

[0053] After installation, the piston rod of the No. 1 electric push rod 4 extends, pushes the top cover 2 to reset and presses the top of the outer cylinder 1 to form a sealed extraction space.

[0054] Next, the heating assembly 3 is activated. Its internal heating elements (such as resistance wire, electric heating tube, PTC ceramic heating plate, etc.) heat the air and deliver it to the inside of the outer cylinder 1. The hot air circulates in the sealed outer cylinder 1, uniformly heating the extraction cylinder 5 so that the material inside the cylinder reaches a suitable extraction temperature.

[0055] At the same time, the drive mechanism 7 starts working, driving the stirring mechanism 6 to rotate. The stirring mechanism 6 stirs the material in the extraction cylinder 5, which on the one hand makes the material heat more evenly and avoids local overheating or uneven temperature; on the other hand, the mechanical stirring accelerates the dissolution and diffusion of silicone oil components in the material, thereby improving the extraction efficiency.

[0056] During the heating and stirring process, the material inside the extraction cylinder 5 may generate gases such as water vapor and volatile impurities due to heating. These gases gather inside the outer cylinder 1. As the gas pressure increases, the exhaust check valve 10 opens to discharge excess gas outside the device. Due to the characteristics of the exhaust check valve 10, outside air cannot enter the outer cylinder 1 in the reverse direction, thereby maintaining a relatively stable internal gas pressure environment and ensuring that the extraction process proceeds safely and orderly.

[0057] After the extraction process is completed, the extracted material is taken out of the cylinder for subsequent separation, purification and other processes. Then, the No. 1 electric push rod 4 is controlled again to open the top cover 2 and disassemble the extraction cylinder 5 for easy cleaning and replacement, meeting the needs of continuous operation and hygiene standards in industrial production.

[0058] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the heating component 3 includes: an air guide shroud 31, a blower 32, and an electric heater 33. The top cover 2 is provided with a rectangular air inlet. The air guide shroud 31 is fixed to the top surface of the top cover 2 and connected to the rectangular air inlet. The blower 32 is connected to one end of the air guide shroud 31. The electric heater 33 is fixed to the bottom surface of the top cover 2 and connected to the rectangular air inlet. With the above scheme, when the heating component 3 is started, the blower 32 starts running first, drawing outside air into the air guide shroud 31.

[0059] The air guide shroud 31 initially guides and collects the air, ensuring its smooth flow towards the rectangular air inlet. The air enters the electric heater 33 through the rectangular air inlet. The electric heating element (such as a resistance wire) inside the electric heater 33 generates heat after being energized, and fully exchanges heat with the air, rapidly heating the air to the set temperature. The heated air then flows along the rectangular air inlet and is transported through the top cover 2 to the interior of the outer cylinder 1. The hot air circulates within the sealed outer cylinder 1, uniformly heating the extraction cylinder 5 and ensuring that the material inside the cylinder reaches a suitable extraction temperature.

[0060] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the stirring mechanism 6 includes a rotating column 61 and multiple sets of stirring paddles 62. The rotating column 61 is rotatably mounted on the extraction cylinder 5, and the bottom end of the rotating column 61 penetrates the bottom end of the extraction cylinder 5. A regular hexagonal insert 611 is fixed at the bottom end of the rotating column 61. Multiple sets of stirring paddles 62 are fixed at equal intervals along the circumference on the outer wall of the rotating column 61. With the above scheme, when in use, the drive mechanism 7 starts to operate, driving the rotating column 61 to rotate around the axis at a set speed. Multiple sets of stirring paddles 62, which are distributed at equal intervals along the circumference, rotate synchronously with the rotating column 61, generating radial and axial stirring effects on the material in the extraction cylinder 5, reducing local temperature differences, and accelerating the crushing of material particles through mechanical shearing force, promoting the dissolution and diffusion of silicone oil components from the solid or mixed phase.

[0061] During the heating and stirring process, the gas generated by the material in the extraction cylinder 5 due to the heat gathers in the outer cylinder 1. When the gas pressure rises, the exhaust one-way valve 10 opens to exhaust the gas and maintain the internal pressure stability.

[0062] Once extraction is complete, the drive mechanism 7 stops operating. Disconnect the hexagonal insert 611 from the drive mechanism 7, and it can be disassembled along with the extraction cylinder 5, making it convenient to clean or replace the stirring paddle 62 and the inner wall of the extraction cylinder 5.

[0063] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the drive mechanism 7 includes: a rotating seat 71, a driven pulley 72, a driving pulley 73, a transmission belt 74, and a drive motor 75. The rotating seat 71 is rotatably installed inside the outer cylinder 1, and a hexagonal slot 711 for the hexagonal insert 611 to be inserted is provided at the top of the rotating seat 71. The driven pulley 72 is fixed on the rotating seat 71, and the driving pulley 73 is rotatably installed on the outer wall of the outer cylinder 1. The transmission belt 74 is tensioned with the driving pulley 73 through the driven pulley 72. The drive motor 75 is fixed on the outer wall of the outer cylinder 1 and is used to drive the driving pulley 73 to rotate. With the above scheme, when the extraction cylinder 5 is installed inside the outer cylinder 1, the hexagonal insert 611 of its stirring mechanism 6 is precisely inserted into the hexagonal slot 711 at the top of the rotating seat 71, forming a mechanical linkage interface.

[0064] After the drive motor 75 is powered on, the output shaft drives the active pulley 73 to rotate, and transmits the rotational power to the driven pulley 72 through the tensioned transmission belt 74. The driven pulley 72 is coaxially fixed with the rotating seat 71, thereby driving the rotating seat 71 to rotate smoothly around the central axis of the outer cylinder 1.

[0065] The rotation of the rotating seat 71 is synchronously driven by the rigid engagement of the hexagonal slot 711 and the hexagonal insert 611, which in turn drives the rotating column 61 to rotate, so that multiple sets of stirring paddles 62 can stir the material in the extraction cylinder 5 at a set speed.

[0066] When it is necessary to disassemble the extraction cylinder 5, there is no need to disassemble the drive mechanism 7. Simply open the top cover 2 with the first electric push rod 4, lift the extraction cylinder 5 upward, and the hexagonal insert 611 can be separated from the hexagonal slot 711 of the rotating seat 71. The whole process does not involve the disassembly or assembly of the belt or motor, which significantly improves the equipment maintenance efficiency.

[0067] In addition, the drive motor 75 is installed on the outer wall of the outer cylinder 1, which isolates it from the high-temperature environment inside and prevents the motor from overheating and being damaged.

[0068] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes a convex ring 51 and a support ring 12. The convex ring 51 is fixed to the top of the extraction cylinder 5, and the support ring 12 is fixed to the inner wall of the outer cylinder 1 to support the convex ring 51. A vent 122 is provided on the support ring 12. With the above solution, when the extraction cylinder 5 is installed in the outer cylinder 1, the hexagonal insert 611 of its stirring mechanism 6 is precisely embedded in the hexagonal slot 711 at the top of the rotating seat 71. At the same time, the convex ring 51 at the top of the extraction cylinder 5 is placed stably on the support ring 12.

[0069] The support ring 12 provides a stable support for the extraction cylinder 5, ensuring that the extraction cylinder 5 remains stable during the stirring process and does not shake or shift, thus ensuring the normal operation of the stirring operation.

[0070] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: multiple positioning rods 121, which are fixed at equal intervals along the circumferential direction to the top surface of the support ring 12. A positioning hole 511 is provided on the convex ring 51 for the positioning rods 121 to pass through. With the above solution, when the extraction cylinder 5 is installed into the outer cylinder 1, the hexagonal insert 611 of its stirring mechanism 6 is precisely embedded in the hexagonal slot 711 at the top of the rotating seat 71. At the same time, the positioning rods 121 pass through the positioning hole 511 to position the installation position of the extraction cylinder 5 and prevent the extraction cylinder 5 from rotating unexpectedly.

[0071] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a pressing mechanism 11 is further included, and the pressing mechanism 11 includes: a pressing block 111 and a second electric push rod 112. The pressing block 111 is located below the top cover 2. When the top cover 2 is flipped to a horizontal state, the pressing block 111 is located directly above the convex ring 51. The second electric push rod 112 is fixed to the top surface of the top cover 2, and the piston rod of the second electric push rod 112 passes through the top cover 2 and is fixedly connected to the pressing block 111. With the above solution, when the first electric push rod 4 pushes the top cover 2 to a horizontal state and presses the top of the outer cylinder 1, the pressing block 111 is located directly above the convex ring 51.

[0072] Next, the second electric push rod 112 is activated, and its piston rod extends downward, driving the pressure block 111 to move downward until the pressure block 111 is tightly pressed against the convex ring 51. In this way, the stability of the extraction cylinder 5 is further enhanced, preventing the extraction cylinder 5 from shaking or shifting due to the movement of materials and the flow of hot air during stirring and heating, thus ensuring the smooth progress of the entire extraction process.

[0073] After the extraction process is completed, first control the piston rod of the second electric push rod 112 to retract, driving the pressure block 111 to move upward and separate it from the convex ring 51. Then, control the first electric push rod 4 to open the top cover 2, and the operator lifts the extraction cylinder 5 upward. At this time, the convex ring 51 separates from the support ring 12, and the extraction cylinder 5 can be smoothly removed from the outer cylinder 1, which facilitates the subsequent processing of the extracted material and also makes it easier to clean and maintain the extraction cylinder 5 and the outer cylinder 1.

[0074] With the cooperation of the convex ring 51, the support ring 12 and the clamping mechanism 11, the entire device not only ensures the stable installation of the extraction cylinder 5, good sealing and heat transfer effect, but also facilitates the disassembly and installation of the extraction cylinder 5, thereby improving production efficiency and equipment maintainability.

[0075] Preferably, by Figure 1 As shown, this embodiment further includes: a discharge hose 8 and a peristaltic pump 9. The inlet end of the discharge hose 8 is connected to the bottom end of the extraction cylinder 5. The peristaltic pump 9 is fixed to the outer wall of the outer cylinder 1, and the outlet end of the discharge hose 8 is connected to the inlet end of the peristaltic pump 9. With the above scheme, when the peristaltic pump 9 is started, the rollers or rotor inside the peristaltic pump 9 will squeeze the discharge hose 8, so that a partial vacuum is formed inside the discharge hose 8. Under the action of this pressure difference, the silicone oil mixture extracted in the extraction cylinder 5 will flow in from the inlet end of the discharge hose 8, be transported through the discharge hose 8 to the inlet end of the peristaltic pump 9, and then be discharged from the outlet end of the peristaltic pump 9 into the designated collection container.

[0076] The peristaltic pump 9 features stable and precisely controllable flow rate, allowing adjustment of the discharge speed of the silicone oil mixture according to actual needs. This prevents the discharge from being too fast or too slow, which could affect subsequent processing steps. Furthermore, during the conveying process, the material only contacts the inner wall of the discharge hose 8, avoiding direct contact between the material and other pump components, thus reducing the risk of material contamination. It also facilitates cleaning and replacement of the discharge hose 8 to adapt to different production requirements. Once the silicone oil mixture in the extraction cylinder 5 has been completely conveyed, the extraction cylinder 5 can be removed from the outer cylinder 1 for cleaning and preparation for the next extraction. Through the coordinated action of all components, the entire device achieves efficient and stable operation of a series of processes, including silicone oil extraction and discharge.

[0077] It should be noted that the blower 32, electric heater 33, electric push rod 4, drive motor 75, peristaltic pump 9, and electric push rod 112 are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0078] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0079] Components not described in detail in this article are existing technologies.

[0080] The working principle and usage process of this utility model: When using the extraction device of this utility model, the piston rod of the first electric push rod 4 is first controlled to extend and retract, thereby driving the top cover 2 to rotate around the hinge point, thus realizing the opening and closing of the top cover 2.

[0081] When it is necessary to add raw materials or replace the extraction cylinder 5, the piston rod retracts and drives the top cover 2 to flip upward, exposing the internal space of the outer cylinder 1. The operator can then install the extraction cylinder 5 containing the reactants into the designated position inside the outer cylinder 1.

[0082] After installation, the piston rod of the No. 1 electric push rod 4 extends, pushes the top cover 2 to reset and presses the top of the outer cylinder 1 to form a sealed extraction space;

[0083] Next, the heating assembly 3 is activated. Its internal heating elements (such as resistance wire, electric heating tube, PTC ceramic heating plate, etc.) heat the air and deliver it to the inside of the outer cylinder 1. The hot air circulates in the sealed outer cylinder 1 to uniformly heat the extraction cylinder 5, so that the material inside the cylinder reaches a suitable extraction temperature.

[0084] At the same time, the drive mechanism 7 starts to work, driving the stirring mechanism 6 to rotate. The stirring mechanism 6 stirs the material in the extraction cylinder 5, which on the one hand makes the material heat more evenly and avoids local overheating or uneven temperature; on the other hand, the mechanical stirring accelerates the dissolution and diffusion of silicone oil components in the material, thereby improving the extraction efficiency.

[0085] During the heating and stirring process, the material inside the extraction cylinder 5 may generate gases such as water vapor and volatile impurities due to heating. These gases gather in the outer cylinder 1. As the gas pressure increases, the exhaust one-way valve 10 opens to discharge excess gas outside the device. Due to the characteristics of the exhaust one-way valve 10, outside air cannot enter the outer cylinder 1 in the reverse direction, thereby maintaining a relatively stable internal gas pressure environment and ensuring that the extraction process is carried out safely and orderly.

[0086] After the extraction process is completed, the extracted material is taken out of the cylinder for subsequent separation, purification and other processes. Then, the No. 1 electric push rod 4 is controlled again to open the top cover 2 and disassemble the extraction cylinder 5 for easy cleaning and replacement, meeting the needs of continuous operation and hygiene standards in industrial production.

[0087] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
