Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil polymer production equipment, in particular to a polymerization reaction kettle for silicone oil production. Background Art

[0002] Polymerization reactor is a multifunctional industrial equipment commonly used in chemical synthesis, biopharmaceuticals, textile industry, coating and paint production, etc. Its main function is to convert raw materials into the desired final product through continuous physical and chemical changes of reaction materials by using high temperature, high pressure, high-speed stirring and other methods, through continuous mixing, stirring, heating and cooling steps.

[0003] Existing silicone oil polymer production reactors all use vertically arranged tanks, and the height of the reactor is relatively high, so the height of the plant needs to be increased to meet the installation requirements of the reactor. The reactor and the drive system are arranged at a relatively high height, and the center of gravity of the reactor as a whole is also relatively high, so it is easy to tip over, and there are very large safety hazards. Based on these problems, Chinese patent CN217189558U discloses a polymerization reactor for producing silicone oil. By providing a fixed column, the purpose of fixing the threaded teeth can be effectively achieved, so that the position of the threaded teeth is more reasonable and more convenient to use. By providing the threaded teeth, the reaction efficiency can be effectively improved under the action of rotation. By providing a feed port, the material can be effectively placed inside the reactor, thereby achieving the purpose of material transmission. By providing a feed hopper, the material can be more conveniently put into the reactor. By providing a slideway, the fixed plate can be effectively made to slide smoothly in the slideway, and a certain limiting purpose can also be achieved. By providing a fixed soft block, the fixed soft block can be attached to the reactor under the action of elasticity, thereby reducing shaking and avoiding rollover. By providing a spring, the clamping purpose can be effectively achieved under the action of elasticity.

[0004] The thread teeth in the reaction tank are not in contact with the inner wall of the reaction tank, and the rotation range of the thread teeth is very limited. Therefore, part of the silicone oil raw material put into the reaction tank is directly accumulated at the bottom of the reaction tank and is not affected by the rotation of the thread teeth. Since the outer shell of the reaction tank cannot be disassembled, it is very difficult to clean the inner wall and the surface of the thread teeth of the reaction tank, which will not only reduce the quality of the finished products of the subsequent silicone oil production, but also affect the service life of the internal components of the reaction tank.
