Description

Technical Field

[0001] This utility model relates to the field of silicone raw material degassing machines, and more specifically, to an anti-sticking structure for the stirring paddle of a silicone raw material degassing machine. Background Technology

[0002] A silicone raw material degassing machine is a device used to remove air bubbles from silicone raw materials, and it is widely used in silicone product manufacturing and other fields. Degassing is typically achieved using a vacuum environment and stirring. Under vacuum, air bubbles in the silicone raw material expand due to the decrease in external pressure. Simultaneously, stirring makes it easier for the bubbles to separate from the raw material and rise to the surface, thus achieving the purpose of degassing.

[0003] During the mixing process, the stirring paddle does work on the silicone raw material, converting mechanical energy into heat energy and raising the material's temperature. For some temperature-sensitive silicone raw materials, excessively high temperatures may alter their chemical and physical properties, such as accelerating the curing reaction and affecting subsequent processing and product quality. How to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0020] 1. When the propeller blades are running, the heat generated is absorbed by the heat dissipation fins. In addition, the intake fan blades accelerate the air circulation inside the insulation tank and dissipate heat from the heat dissipation fins, ensuring that the heat dissipation fins absorb the heat inside the heat conduction tank. This solves the problem that the heat inside the existing degassing machine cannot be dissipated during use, which leads to a gradual increase in internal temperature.

[0021] 2.

At the same time, the special shape of the propeller blade allows the silicone raw material to flow in a spiral manner along the surface of the propeller blade when the blade rotates. Compared with other shapes of propeller blades, the tilt angle and curved surface design of the propeller blade can guide the material flow and reduce the residence time of the material on the surface of the propeller blade, thereby further preventing the silicone raw material from adhering to the surface of the propeller blade.

The support plate 701 is fixedly connected to the top of the insulation can 1, the top plate 702 is fixedly connected to the bottom of the support plate 701, the motor 703 is fixedly connected to the top of the top plate 702, the rotating shaft 704 is mounted on the bottom output end of the motor 703, the intake fan blade 705 is fixedly connected to the bottom end of the rotating shaft 704, the filter 706 is fixedly connected to the top of the interior of the insulation can 1, and the bottom end of the rotating shaft 704 passes through the filter 706 and extends to below the filter 706. The outer wall of the rotating shaft 704 is rotatably connected to the inner wall of the filter screen 706 through which it is penetrated. After the motor 703 is started, the rotating shaft 704 can rotate inside the filter screen 706. The heat conduction tank 707 is set inside the heat insulation tank 1. The outer wall of the heat conduction tank 707 is fixedly connected to the fixing rod 7071. The inner wall of the heat insulation tank 1 is fixedly connected to one end of the fixing rod 7071. One end of the air extraction pipe 5 is connected to the inside of the heat conduction tank 707. The fixing rod 7071 can support the heat conduction tank 707. The air inside the heat conduction tank 707 can be extracted through the air extraction pipe 5. The heat dissipation fins 708 are fixedly connected to the outer wall of the heat conduction tank 707.

[0031] The stirring assembly 8 includes a transmission component 801, a threaded column 802, a collar 803, an output shaft 804, a locking block 805, a locking groove 806, a reduction gear set 807, and a propeller blade 808. The transmission component 801 is mounted on the outer wall of the rotating shaft 704, and the driving wheel of the transmission component 801 is fixedly connected to the outer wall of the rotating shaft 704. The threaded column 802 is located above the closing plate 4, and the driven wheel of the transmission component 801 is located at the top of the threaded column 802 and fixedly connected to the threaded column 802. When the rotating shaft 704 rotates, the threaded column 802 can be driven to rotate through the transmission component 801. The collar 803 is sleeved on the outer wall of the threaded column 802 and is threadedly connected to the threaded column 802. The output shaft 804 is located at the bottom end of the threaded column 802. The outer wall of the output shaft 804 is provided with a thread that matches the inner wall of the collar 803. By rotating the collar 803, the collar 803 can be moved to the outer wall of the threaded column 802 and the outer wall of the output shaft 804 under the action of the thread. The locking block 805 is fixedly connected to the bottom end of the threaded column 802. The locking groove 806 is opened at the top end of the output shaft 804.

The reduction gear set 807 is installed at the bottom end of the output shaft 804, and the propeller blade 808 is installed at the bottom of the reduction gear set 807.

[0032] When the propeller blade 808 is running, the heat generated is absorbed by the heat dissipation fins 708. Furthermore, when the intake fan blade 705 is running, it accelerates the airflow inside the insulation tank 1 and dissipates heat from the heat dissipation fins 708. This ensures that the heat dissipation fins 708 absorb the heat inside the heat conduction tank 707, thereby solving the problem that the heat inside the existing degassing machine cannot dissipate during use, resulting in a gradual increase in internal temperature.

[0033] By dissipating heat inside the heat-conducting tank 707, the degassing of the silicone raw material under high temperature can be effectively avoided, which would lead to excessive liquefaction of the silicone raw material and cause it to adhere to the surface of the propeller blade. At the same time, the special shape of the propeller blade 808 allows the silicone raw material to flow in a spiral manner along the surface of the propeller blade 808 when the blade rotates. Compared with other shapes of propeller blades, the tilt angle and curved surface design of the propeller blade 808 can guide the material flow and reduce the residence time of the material on the surface of the blade, thereby further preventing the silicone raw material from adhering to the surface of the blade.

[0034] The working principle of the anti-sticking structure of the stirring paddle in this silicone raw material degassing machine is as follows: The silicone raw material is poured into the heat-conducting tank 707 and sealed by the sealing plate 4. Then, the air inside the heat-conducting tank 707 is extracted through the air extraction pipe 5, and the motor 703 is started. The motor 703 drives the suction fan blade 705 and the propeller blade 808 to rotate through the rotating shaft 704 and the transmission component 801, respectively. When the propeller blade 808 rotates, it will cause the silicone raw material inside the heat-conducting tank 707 to tumble and expel the air inside. At the same time, the heat generated by the propeller blade 808 during operation will be absorbed by the heat dissipation fins 708 and transported to the inside of the insulation tank 1. When the suction fan blade 705 rotates, it can draw low-temperature outside air into the inside of the insulation tank 1 through the filter screen 706 and dissipate heat from the heat dissipation fins 708. After the propeller blade 808 completes the degassing process of the silicone raw material, it can be directly discharged and used for subsequent processing operations.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
