Technical Field

[0001] This utility model relates to the field of silicone oil processing technology, and in particular to a continuous silicone oil preparation apparatus. Background Technology

[0002] Silicone oil typically refers to linear polysiloxane products that remain liquid at room temperature. They are generally divided into two categories: methyl silicone oil and modified silicone oil, and are currently widely used.

[0003] Currently, silicone oil production requires a continuous production equipment. The most important step in the production process is the reaction process of the reactants. In existing continuous silicone oil production equipment, the reaction tank often suffers from poor mixing of reactants and additives. Utility Model Content

[0004] The purpose of this invention is to provide a continuous silicone oil preparation device to solve the problem of poor mixing effect between reactants and additives in the reaction tank of existing continuous silicone oil preparation devices.

[0005] To achieve the above objectives, this utility model provides a continuous preparation apparatus for silicone oil, including a base, a dissolving tank installed on the left side of the base, a mixing tank installed on the right side of the base, and a mixing component;

[0006] The mixing assembly includes an inlet seat, a lower sealing seat, an upper sealing seat, a rotating tube, a first infusion tube, a second infusion tube, a connecting tube, a driving component, and a mating component. The inlet seat is fixed to the top of the mixing tank, the lower sealing seat is fixed to the bottom of the inlet seat, and the upper sealing seat is fixed to the top of the inlet seat. The rotating tube has a non-penetrating water passage cavity running from bottom to top, and the water inlet groove at the top, which communicates with the water passage cavity, also communicates with the water storage cavity inside the inlet seat. Sealing rings are provided in the inner holes of the lower and upper sealing seats that respectively contact the rotating tube. The first infusion tube is welded to the rotating tube, and its outlet is inclined downwards at intervals. The second infusion tube is longer than the first infusion tube, and its outlet is inclined downwards at intervals. The connecting tube is connected to the inlet seat and is located on the left side of the inlet seat. The driving component is located at the top of the mixing tank and is used to drive the rotating tube to rotate. The mating component is located on the side of the dissolving tank near the mixing tank.

[0007] The cooperating components include a dehydration component and a first electric valve. The dehydration component is connected to the input side of the connecting pipe via a pipeline. The first electric valve is installed at the bottom of the dissolving tank and is connected to the input side of the extraction pump of the dehydration component via a pipeline.

[0008] The cooperating components also include a second electric valve and a discharge component. The second electric valve is fixed to the bottom of the mixing tank, and the discharge component is located on the output side of the second electric valve.

[0009] The discharge component includes a low molecular weight removal chamber and a discharge pipe. The low molecular weight removal chamber is connected to the second electric valve via a pipe. The discharge pipe is installed on the output side of the low molecular weight removal chamber.

Multiple waterproof motors are installed in a ring at intervals on the mixing tank. The connecting shaft of the stirring blade is connected to the output shaft of the waterproof motor via a coupling.

[0011] This invention relates to a continuous silicone oil preparation device. During processing, the raw materials are first dissolved in a dissolving tank to obtain a mixture. A sealing agent is then injected into the mixing tank through a feed pipe at the top. After dehydration, the mixture is pumped into the mixing tank. The mixture is then transported into the water-filled cavity of the inlet seat and enters the water-passing cavity through a water inlet trough at the top of the rotating pipe. Finally, the mixture is rapidly and widely transported via a first and second inlet pipe as the rotating pipe rotates, facilitating rapid and extensive mixing with the sealing agent. The first and second inlet pipes simultaneously perform a stirring function during rotation, thus solving the problem of poor mixing between reactants and additives in existing continuous silicone oil preparation devices.

The connecting tube 110 is connected to the inlet seat 104 and is located on the left side of the inlet seat 104. The driving component 111 is located on the top of the mixing tank 103 and is used to drive the rotating tube 107 to rotate. The mating component is located on the side of the dissolving tank 102 near the mixing tank 103. The inlet seat 104 is fixed by bolts, and the lower sealing seat 105 and the upper sealing seat 106 are fixed by bolts respectively. The lower sealing seat 105 is provided with a bearing mounting cavity to facilitate the installation of the rotating tube 107 through the bearing. The top of the bearing is limited by a limiting cover plate for outer ring limitation, and the inner ring is limited by a snap ring installed on the rotating tube 107. A sealing block is installed on the bottom end face of the rotating tube 107 for sealing, and it does not penetrate the water passage cavity from bottom to top. The water inlet groove at the top, which communicates with the water passage cavity, is also connected to the water storage cavity inside the inlet seat 104 to facilitate the passage of the mixed liquid. The first infusion tube 108 and the second infusion tube 109 are respectively welded and fixed to the rotating tube 107 to achieve fixation and communication for infusion.
