Carrier chemical modification treatment equipment for producing catalyst based on impregnation method

Abstract

The carrier chemical modification treatment equipment comprises a mixing box, a rotating shaft is rotationally connected to the top of the mixing box, a stirring motor is arranged on the outer wall of the top of the rotating shaft, a liquid inlet and a feeding port are formed in the two sides of the stirring motor, and a plurality of stirring shafts are fixedly connected to the outer wall of the rotating shaft; a mounting plate is fixedly connected to the interior of the rotating shaft, a main shaft is rotatably connected to the outer wall of the mounting plate, a rotating motor is arranged on the outer wall of the top of the main shaft, a plurality of first bevel gears are fixedly connected to the outer wall of the main shaft, and the outer walls of the first bevel gears are engaged with a plurality of second bevel gears; the second bevel gears are fixedly connected to the outer wall of one side of the auxiliary shaft. When the moving belt moves, the plurality of stirring plates on the moving belt move from bottom to top, so that a compound moving towards the center can be stirred to the outer ring, and the compound and liquid can be fully and uniformly mixed.

Description

technical field [0001] The invention relates to the technical field of chemical modification treatment, in particular to a carrier chemical modification treatment device for producing catalyst based on impregnation method. Background technique [0002] The impregnation method is based on the principle that the active component impregnates the porous support in the form of a salt solution and penetrates into the inner surface to form a high-efficiency catalyst. Usually, the liquid containing the active substance is de-impregnated with various types of carriers. After the impregnation is balanced, the remaining liquid is removed, and then the same post-processing as the precipitation method is performed, such as drying, roasting, and activation, so that the salts of the active components are left in the carrier. On the inner surface, the salts of these metals and metal oxides are uniformly distributed in the pores of the carrier, and after being decomposed and activated by hea...

Problems solved by technology

[0003] In chemical modification, the impregnation method is also used. Before using the impregnation method, it is necessary to prepare a solution. The configuration of the solution is to throw the compound into the liquid and then stir and mix it. At present, the stirring is generally driven by the rotating shaft. The stick stirs the compound and the liquid, but this simple stirring method will lead to insufficient mixing of the compound and the liquid, which will affect the subsequent chemical modification work
