Low-loss silicone oil processing system

Abstract

The invention discloses a low-loss silicone oil processing system which comprises a raw material tank and a finished product tank which are correspondingly arranged and are both constructed into an existing metal tank body structure; the device further comprises a reaction kettle part, the lower end of the reaction kettle part is fixedly connected and communicated with the raw material tank and the finished product tank through two communicating pipes, a supporting and fixing frame body is arranged between the reaction kettle part and the raw material tank and between the reaction kettle part and the finished product tank, and the upper end and the lower end of the reaction kettle part are provided with a leading-out part and a leading-in part respectively. A heating and stirring assembly is also arranged in the reaction kettle part. According to the present invention, the existing silicone oil reduced pressure distillation structure is improved, the continuous reduced pressure distillation action can be achieved by introducing the reaction mixture and exporting the low-boiling-point substance steam and the silicone oil finished product, and compared with the existing repeated reduced pressure distillation equipment, the overall silicone oil processing efficiency is high, and the production cost is low. In the actual processing process, the reaction kettle can be always in a low-pressure sealing state, so that the loss of silicone oil is low.

Description

technical field [0001] The invention relates to equipment for processing silicone oil, in particular to a low-loss silicone oil processing system. Background technique [0002] Silicone oil needs to be prepared after a series of reactions with raw materials during production. The main preparation and processing equipment is the reactor. At the same time, after the silicone oil is obtained from the reaction in the reactor, it needs to be distilled under reduced pressure to obtain the finished silicone oil; The equipment is installed between the reaction kettle and the finished product tank, and the silicone oil mixture in the cooled reaction kettle enters the finished product tank after vacuum distillation. The existing vacuum distillation method of silicone oil is often composed of a reaction kettle and a collection tank. The two form a chamber structure, and the silicone oil mixture is passed into the reaction kettle, and then the pressure inside the chamber is reduced by a...

Problems solved by technology

The existing vacuum distillation method of silicone oil is often composed of a reaction kettle and a collection tank. The two form a chamber structure, and the silicone oil mixture is passed into the reaction kettle, and then the pressure inside the chamber is reduced by a vacuum pump, and the silicone oil mixture is The low boiling matter in the medium is removed. Under low pressure, the low boiling matter can be removed after heating to a certain temperature, and at the same time, the silicone oil will not be evaporated to cause the loss of silicone oil. However, this commonly used vacuum distillation method still has problems. First of all, in the process of vacuuming, it is necessary to vacuumize the reactor and the collection tank at the same time, so as to ensure that the mixture is in a low-pressure state during the actual vacuum distillation process, and the current silicone oil vacuum distillation method is often for certain The operation of reducing the volume of the mixture to conduct a vacuum distillation and exporting the finished product, and then repeating the operation, such a vacuum distillation method does not have high work efficiency at first, and at the same time, when performing the vacuum distillation operation repeatedly, every time When performing one operation, it is necessary to repeatedly vacuumize the reactor, resulting in more expensive operations, and each repeated operation is troublesome, and in the process of vacuum distillation of silicone oil, one-time For the operation of a large amount of mixture, it is easy to cause uneven heating and boiling splashing, so that the silicone oil is entrained into the collection tank, resulting in loss
