Description

Technical Field

[0001] This utility model relates to the technical field of silicone oil production equipment, and in particular to a material mixing device for silicone oil production. Background Technology

[0002] In the production process of hydrogen-containing silicone oil, it is first necessary to prepare monomethyl hydrogen-containing monomer and trimethyl monomer. Then, the monomethyl hydrogen-containing monomer and trimethyl monomer are transported to a storage tank for mixing. The mixture is then fed into a reactor with a catalyst for hydrolysis. The hydrolysate is dried and then fed into a polymerization reactor. The polymerized product is then subjected to desulfurization and decolorization treatment to obtain the finished hydrogen-containing silicone oil. During the mixing of monomethyl hydrogen-containing monomer and trimethyl monomer, the temperature needs to be controlled. At higher temperatures, trimethyl monomer is prone to decomposition, producing hydrogen chloride gas. In order to fully mix the monomethyl hydrogen-containing monomer and trimethyl monomer, a mechanical stirring device is often installed in the tank. However, the motor of the mechanical stirring device is prone to overheating, and heat conduction causes the temperature inside the tank to rise, affecting the production process. This needs to be improved. Utility Model Content

Detailed Implementation

[0016] like Figures 1 to 3As shown, a material mixing device for silicone oil production includes a vertically arranged tank 1. A central cooling pipe assembly is coaxially arranged inside the tank 1 and rotatably connected to the tank 1. Several cooling circuit assemblies are installed on the central cooling pipe assembly, forming a multi-stage zigzag cooling flow channel with the central cooling pipe assembly and the cooling circuit assemblies. A turbine ring 15 is fixedly fitted on the tank 1, and the turbine ring 15 meshes with a worm shaft 16. The worm shaft 16 is driven by a motor and is rotatably connected to a gantry frame 14. A load-bearing component is connected to the bottom of the gantry frame 14, located below the tank 1. The tank 1 and the load-bearing component are in rolling contact. The central cooling pipe assembly is fixedly connected to the top of the gantry frame 14.

[0017] More specifically, such as Figure 3 As shown, the central cooling pipe assembly includes a central pipe 2 sealed at both ends. A vertical partition 3 is vertically connected inside the central pipe 2, dividing the inner cavity of the central pipe 2 into two chambers. A connecting hole 7 is provided at the bottom of the partition 3. An inlet pipe 8 and an outlet pipe 9 are connected to the central pipe 2, and the inlet pipe 8 and the outlet pipe 9 are respectively connected to the two chambers. The cooling circuit assembly includes a U-shaped pipe 6, which is fixedly connected to the central pipe 2. Several horizontal partitions 4 are installed vertically inside the central pipe 2. Several pairs of water passage holes 5 are provided on the central pipe 2. Each pair of water passage holes 5 is located above and below the horizontal partitions 4, and each pair of water passage holes 5 is respectively connected to the inlet and outlet of the U-shaped pipe 6. To facilitate disassembly and replacement and to increase sealing, the U-shaped pipe 6 is fixedly connected to the central pipe 2 by bolts, and a sealing ring is provided between the central pipe 2 and the U-shaped pipe 6.

[0018] like Figure 4 As shown, to ensure the smooth rotation of the tank 1, the load-bearing component includes a load-bearing ring 10, which is fixedly mounted on the gantry frame 14.
