Description

Technical Field

[0001] The utility model is applicable to the technical field of tert-butyl perbenzoate production, and particularly relates to mixing equipment for producing tert-butyl perbenzoate. Background Art

[0002] At present, tert-butyl peroxybenzoate is widely used as an initiator in polymerization processes such as ethylene, styrene, propylene, vinyl acetate, diallyl phthalate and isobutylene. When preparing and producing it, it is necessary to use the synthesis of tert-butyl peroxybenzoate. 30% of sodium hydroxide is put into a reactor such as a reactor already equipped with tert-butyl hydrogen peroxide, an appropriate amount of clean water is added, and a certain amount of benzoyl chloride is then added dropwise. After the addition is completed, the temperature is kept for several hours to allow it to fully react and prepare.

[0003] However, in the preparation of tert-butyl perbenzoate, multiple raw materials are added in sequence and then stirred. During the stirring reaction, the materials will splash, causing the liquid raw materials to splash and adhere to the inner wall of the tank as the reaction continues, making this part of the raw materials unable to participate in the subsequent processing reaction, thereby affecting the utilization rate of the materials. Therefore, we propose a mixing device for the production of tert-butyl perbenzoate. Utility Model Content

[0007] The outer surface of the transmission rod is slidably sleeved with a lifting sleeve, and transmission plates are fixedly installed on the outer surfaces of both ends of the lifting sleeve, and shielding plates are fixedly installed on the bottom surfaces of the two groups of lifting sleeves, and the bottom surface of the transmission plate is fixedly installed on the top surface of the shielding plate, and the two sides of the top of the sealing cover are fixedly installed with fixed frames, and the inner surface of each fixed frame is fixedly installed with an electric push rod, and the bottom of the electric push rod transmission shaft is fixedly connected to the top surface of the transmission plate through a coupling;

[0009] By adopting the above technical solution, after the electric push rod drives the vertical movement of the transmission plate and the lifting sleeve, the vertical position of the baffle plate inside the reaction tank can be adjusted so that it can always fit above the liquid surface of the mixed material. Combined with the rotational driving action of the scraper plate by the fixed rod, it is ensured that the material will not splash excessively and adhere to the inner wall of the reaction tank above the liquid surface. At the same time, the material adhering to the barrel wall is scraped and removed to avoid affecting the reaction utilization rate of the material.

[0010] As an optional solution of the technical solution of the present application, a mounting frame is fixedly installed on the middle surface of the top of the sealing cover, a servo motor is fixedly installed on the inner surface of the mounting frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top surface of the transmission rod through a coupling.

[0013] By adopting the above technical solution, the quantitative feeding process of the material is ensured through the structural function of the quantitative barrel and the control valve.

[0015] By adopting the above technical solution, the vertical movement stability of the lifting sleeve is ensured by the guiding sliding action of the guide groove on the guide block.
