Description

Technical Field

[0001] This utility model relates to the field of silicone rubber production technology, specifically a dehydration kettle for silicone rubber production. Background Technology

[0002] Silicone rubber is a high-molecular-weight organosilicon compound with silicon dioxide as its basic backbone. It possesses many unique properties and a wide range of applications. Silicone rubber refers to rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups usually attached to the silicon atoms. Silicone rubber has excellent temperature resistance, weather resistance, electrical insulation, physiological inertness, and air permeability.

[0003] In the production of silicone rubber, a dehydration kettle is needed to dehydrate the raw materials. Utility model patent CN218458646U discloses a dehydration kettle for silicone rubber production, including a kettle body and partitions. An electromechanical box and a nitrogen tank are fixedly connected to the upper surface of the kettle body. A forward and reverse motor is fixedly connected to the inner top wall of the electromechanical box. This utility model sets a central rotating rod inside the kettle body and four sets of stirring and fixing plates on the surface of the central rotating rod, with through grooves opened on the stirring and fixing plates. This allows the stirring and fixing plates to uniformly stir the raw materials inside the kettle body, facilitating thorough and uniform heating of the raw materials by the electric heating wires inside the stirring and fixing plates, ensuring uniform heating. Furthermore, by setting up a nitrogen tank, nitrogen can be introduced into the kettle body. Through the main rotating wheel, the driven rotating wheel, and the transmission belt, the moving nozzle can move up and down on the surface of the threaded rod, achieving the purpose of vertical nitrogen input. This can quickly and completely expel the water vapor generated inside the kettle body, thereby improving the dehydration efficiency inside the kettle body.
