Abstract

The invention relates to the field of catalyst preparation, and discloses a mixing device for mixing catalyst carrier raw materials, and a mixing method thereof. The mixing device for mixing the catalyst carrier raw materials comprises: a mixing chamber (1), wherein the mixing chamber (1) is defined by an upper sealing cover (11), a lower sealing cover (13) and a barrel (12); a stirring unit (2) comprising a main shaft (21), a connecting shaft (22) and a stirring paddle (23), wherein the main shaft (21) penetrates through the upper sealing cover (11) and is connected with the connecting shaft (22), and the stirring paddle (23) is arranged on the connecting shaft (22); a feeding hole (3) formed in the upper sealing cover (11); a liquid inlet (4) formed in the upper sealing cover (11); and a discharge hole (5) formed in the lower sealing cover (13). According to the invention, the invention provides the mixing device capable of realizing uniform, automatic and clean mixing process of the catalyst carrier raw materials, and the method using the mixing device.

Description

Technical field [0001] The present invention relates to the field of catalyst preparation, and more particularly to a mixing method for mixing a mixing device and a catalyst carrier feedstock for a catalyst carrier feedstock. Background technique [0002] In the production of catalyst carriers in the field of petrochemicals, the main raw material of the carrier and the dry mix of the powder and the binder, and the wet method of the dry blended material and the liquid feedstock, which is an important factor affecting the performance of the catalyst carrier. One. At present, in the production of hydrogenated catalyst industrial production, the carrier feedstock is produced by a crank kneading machine, and it is necessary to manually purse, hydraulic tunnel artificial discharge, production process labor intensity, and harsh. At the same time, since various powder raw materials are inconsistent during the dry mix, the wet mixing process needs to be added to a certain proportion of li...
