Problems solved by technology
However, at present, most of the suction volume adjustment mechanisms of the vacuum system for the production of silica products cannot finely and flexibly adjust the orientation (height, orientation, and inclination angle) of the suction machine on it, resulting in the suction pipe of the suction machine It is not convenient to extend into the exhaust pipe of some vacuum systems, so it cannot be applied to various vacuum systems

The invention discloses a vacuum system air exhaust amount adjusting mechanism for white carbon black product production with methyl methacrylate as a raw material. The mechanism comprises a supporting base and an air exhauster arranged on the inner side of the supporting base, and an air exhaust pipe is fixedly connected to the air exhauster. An attaching assembly comprises a steel ring annularlyconnected to the outer wall of the air exhaust pipe in a sleeving mode, a rubber sleeve bonded to the outer wall of the steel ring, two springs located on the inner side of the rubber sleeve and fixedly connected with the two sides of the outer wall of the steel ring, two positioning blocks fixedly connected with the two springs correspondingly, and elastic rubber rings bonded and fixed to the two positioning blocks correspondingly. A driving cavity used for containing the driving assembly is formed in the supporting base, a lifting plate is arranged on the inner side of the supporting base,and an adjusting assembly is arranged on the lifting plate. According to the vacuum system air exhaust amount adjusting mechanism for white carbon black product production with methyl methacrylate asthe raw material, the air exhaust pipe can extend into vacuum system air exhaust pipe openings in different directions and different positions, and therefore the vacuum system air exhaust amount adjusting mechanism is suitable for air exhaust of different vacuum systems.
Description
technical field [0001] The invention belongs to the technical field of production of white carbon black products, and in particular relates to a mechanism for regulating the pumping volume of a vacuum system used in the production of white carbon black products using Yijia as a raw material. Background technique [0002] White carbon black is the general term for white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic silicic acid aluminum and calcium silicate etc. Silica is a porous substance, and its composition can be represented by SiO2 nH2O, where nH2O exists in the form of surface hydroxyl groups, soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). [0003] When producing white carbon black, it is necessary to use Yijia as a raw material in the vacuum system, vacuumize the inner cavit...
