Description

Technical Field

[0001] This utility model relates to the field of silicone product manufacturing technology, specifically to an impurity cleaning device for silicone product manufacturing. Background Technology

[0002] Silicone products are made from siloxane polymers and have good elasticity, high temperature resistance, corrosion resistance and non-deformation properties. Silicone is widely used in kitchenware, daily necessities and medical devices. Due to its environmentally friendly, non-toxic and easy-to-clean characteristics, it is increasingly favored by consumers.

[0003] During the production and processing of silicone products, a vulcanizing agent needs to be added for vulcanization treatment. The vulcanizing agent combines with the siloxane segments through chemical reaction, promoting the cross-linking reaction and forming a more stable three-dimensional network structure. In this process, some low-molecular impurities in the raw materials, such as unreacted monomers or low-molecular polymers, will be converted into volatile substances due to their unstable state and volatilize as the temperature rises, thus achieving the purpose of removing impurities from silicone products.

[0004] However, existing silicone product impurity removal equipment mainly uses external heating or heat transfer methods that concentrate heat into the equipment, resulting in uneven heat distribution within the equipment, which affects the impurity removal effect. Utility Model Content

[0005] The purpose of this invention is to provide an impurity cleaning device for silicone product manufacturing, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] An impurity cleaning device for silicone product manufacturing includes a reaction vessel. A hollow, bottom-sealed rotating rod is coaxially rotatably mounted inside the reaction vessel, with its bottom end extending through to the top of the reaction vessel. An inner tube, with both ends penetrating through, is coaxially mounted inside the rotating rod via a connecting frame, with its top end extending through to the top of the rotating rod. Stirring rods made of aluminum are evenly distributed on the outer wall of the rotating rod inside the reaction vessel, each stirring rod extending through to the inner tube. A heat source assembly for supplying heated air from top to bottom into the inner tube is provided above the reaction vessel. A drive mechanism for driving the rotating rod to rotate is provided at the top of the reaction vessel.

[0008] As can be seen, the heat source component heats the air and supplies it into the inner tube, forming a downward hot airflow inside the inner tube. The stirring rod is made of aluminum and extends into the inner tube, absorbing heat and transferring it to the reaction vessel for heating. The stirring rod is evenly distributed on the rotating rod, ensuring a large heating coverage area inside the reaction vessel as it rotates and stirs, thus ensuring faster and more uniform heating and effectively improving the impurity removal efficiency. The stirring rod serves as both a stirring component and a heating component, achieving two goals at once.

[0009] Furthermore, the heat source components include a bracket, an air inlet duct, electric heating meshes, and a fan. The air inlet duct is installed above the reaction vessel via the bracket, and the bottom end of the air inlet duct is rotatably connected to the top of the inner tube. Multiple electric heating meshes are evenly distributed inside the air inlet duct from top to bottom, and a fan is installed inside the air inlet duct below the bottommost electric heating mesh.

[0010] Furthermore, the outer diameter of the inner tube is smaller than the inner diameter of the rotating rod, the bottom end of the inner tube does not contact the inner bottom wall of the rotating rod, and a drainage cavity communicating with the inside of the rotating rod is formed between the outer wall of the inner tube and the inner wall of the rotating rod.

[0011] Furthermore, the drive mechanism includes a drive motor, a main gear, and a driven gear ring. The drive motor is fixed to the top of the reaction vessel, the main gear is fixed to the output shaft of the drive motor, and the driven gear ring is fixedly fitted onto the outside of the rotating rod and meshes with the main gear.

[0012] Furthermore, stirring plates are evenly distributed on the outer wall of the rotating rod near the bottom of the reaction vessel.

[0013] Furthermore, a dust filter is installed inside the air inlet duct near its top.

[0014] Furthermore, the reaction vessel has two feeding ports at the top and a discharge port at the bottom, with a discharge valve installed on the discharge port.

[0015] Furthermore, the bottom of the reaction vessel has a diameter that decreases towards the bottom and gradually converges towards the outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] This invention heats air through a heat source assembly and supplies it into the inner tube, forming a downward hot airflow within the inner tube. The stirring rod, made of aluminum, extends into the inner tube and absorbs heat, transferring it to the reaction vessel for heating. The stirring rod is evenly distributed on the rotating rod, ensuring a large heating coverage area within the reaction vessel as it rotates and stirs, thus ensuring faster and more uniform heating and effectively improving impurity removal efficiency. The stirring rod serves as both a stirring element and a heating element, achieving two goals at once.

[0018] This invention designs the bottom of the inner tube to be higher than the inner bottom wall of the rotating rod, so that the bottom of the inner tube does not contact the inner bottom wall of the rotating rod. This creates a drainage channel between the inner wall of the rotating rod and the outer wall of the inner tube. The downward hot airflow inside the inner tube is redirected and discharged upward through the drainage channel, which helps to form a flowing heat flow, achieve a continuous heat source supply, and ensure the durability of heating.

[0019] In this invention, each stirring rod extends through the drainage channel into the inner tube. When the hot flow rises and exits in the drainage channel, it can contact the stirring rod again, thereby heating the stirring rod again and effectively improving the heat utilization rate.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0028] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0029] Please see Figures 1-5 This utility model provides an impurity cleaning device for silicone product production, including a reaction tank 1. A hollow rotating rod 2 with a sealed bottom is coaxially rotatably installed inside the reaction tank 1. The bottom end of the rotating rod 2 extends through to the top of the reaction tank 1. An inner tube 3 with both ends through is coaxially installed inside the rotating rod 2 via a connecting frame. The top end of the inner tube 3 extends through to the top of the rotating rod 2. Stirring rods 21 made of aluminum are evenly distributed on the outer wall of the rotating rod 2 inside the reaction tank 1. Each stirring rod 21 extends through to the inner tube 3. A heat source assembly 5 is provided above the reaction tank 1 for supplying heated air from top to bottom into the inner tube 3. A drive mechanism 4 is provided at the top of the reaction tank 1 for driving the rotating rod 2 to rotate.

[0030] The impurity cleaning device provided by this utility model involves placing silicone material and vulcanizing agent into a reaction tank 1. The vulcanizing agent then undergoes a chemical reaction to remove impurities from the silicone material. During the cleaning process, the drive mechanism 4 drives the rotating rod 2 to rotate, which in turn causes the stirring rod 21 to oscillate within the reaction tank 1, achieving a stirring effect. This ensures that the vulcanizing agent and impurities in the silicone material are evenly mixed and reacted, improving the impurity removal efficiency. Furthermore, the heat source component 5 heats the air and supplies it to the inner tube 3, creating a downward hot airflow within the inner tube 3. The stirring rod 21, made of aluminum and extending into the inner tube 3, absorbs heat and transfers it to the reaction tank 1 for heating, accelerating the volatilization of the vulcanizing agent and impurities. The stirring rod 21 is evenly distributed on the rotating rod 2, ensuring a large heating coverage area within the reaction tank 1 as it rotates and stirs, thus ensuring faster and more uniform heating and effectively improving the impurity removal efficiency. The stirring rod 21 serves as both a stirring element and a heating element, achieving two functions at once.

[0031] Specifically, the heat source component 5 includes a bracket 51, an air inlet duct 52, an electric heating mesh 53, and a fan 54. The air inlet duct 52 is installed above the reaction tank 1 via the bracket 51. The bottom end of the air inlet duct 52 is rotatably connected to the top of the inner tube 3. Multiple electric heating meshes 53 are evenly distributed from top to bottom inside the air inlet duct 52. A fan 54 is installed below the bottommost electric heating mesh 53 inside the air inlet duct 52. When the fan 54 operates, external air is drawn into the air inlet duct 52. The electric heating meshes 53 are energized and heated, which heats the air entering the air inlet duct 52, thereby forming a downward hot airflow that is supplied to the inner tube 3 to heat the stirring rod 21 as a heat source. In addition, multiple electric heating meshes 53 are evenly distributed to achieve multi-layer heating, which makes the air heating more thorough and faster.

[0032] In addition, a dust filter 521 is installed near the top of the air inlet duct 52 to filter out dust particles and impurities in the air, which may accumulate excessively in the rotating rod 2 and the inner tube 3, thus affecting the normal flow of heat.

[0033] Specifically, the outer diameter of the inner tube 3 is smaller than the inner diameter of the rotating rod 2, and the bottom end of the inner tube 3 does not contact the inner bottom wall of the rotating rod 2. An exhaust channel 31 communicating with the inside of the rotating rod 2 is formed between the outer wall of the inner tube 3 and the inner wall of the rotating rod 2. The design that the bottom end of the inner tube 3 is higher than the inner bottom wall of the rotating rod 2 ensures that the bottom end of the inner tube 3 does not contact the inner bottom wall of the rotating rod 2, thereby forming an exhaust channel 31 between the inner wall of the rotating rod 2 and the outer wall of the inner tube 3. After the downward hot air flow in the inner tube 3 is reversed, it is discharged upward from the exhaust channel 31, which helps to form a flowing hot air flow, realize a continuous heat source supply, and ensure the persistence of heating.

[0034] In addition, each stirring rod 21 extends through the drainage channel 31 into the inner tube 3. When the hot flow is discharged upward in the drainage channel 31, it can come into contact with the stirring rod 21 again, thereby heating the stirring rod 21 again, effectively improving the heat utilization rate.

[0035] Specifically, the drive mechanism 4 includes a drive motor 41, a main gear 42, and a driven gear ring 43. The drive motor 41 is fixed to the top of the reaction vessel 1, the main gear 42 is fixed to the output shaft of the drive motor 41, and the driven gear ring 43 is fixedly fitted on the outside of the rotating rod 2 and meshes with the main gear 42. When the drive motor 41 works, its output shaft drives the main gear 42 to rotate. The rotating main gear 42 meshes with and drives the driven gear ring 43, which in turn drives the rotating rod 2 to rotate, thus providing a drive for stirring.

[0036] Specifically, stirring plates 22 are evenly distributed on the outer wall of the rotating rod 2 near the bottom of the reaction tank 1. During the rotation of the rotating rod 2, the stirring plates 22 can be driven to rotate synchronously. The stirring plates 22 achieve a stirring effect at the bottom of the reaction tank 1, which can prevent the sulfurizing agent from settling and further improve the impurity removal effect.

[0037] Specifically, the top of the reaction tank 1 is provided with two feeding ports 11, one feeding port 11 is used to feed silicone material and the other feeding port 11 is used to feed vulcanizing agent. The bottom of the reaction tank 1 has a discharge port 12, and a discharge valve 121 is installed on the discharge port 12. The discharge port 12 is used to discharge the processed silicone material.

[0038] In addition, the bottom of the reaction vessel 1 has a diameter that gradually decreases downwards and converges towards the outlet 12, which is beneficial for draining the silica gel material inside the reaction vessel 1.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
