Screening and filling device for preparation of ammonia synthesis catalyst

Abstract

The invention relates to the technical field of catalyst production, in particular to a screening and filling device for preparation of an ammonia synthesis catalyst. The screening and filling devicecomprises a carrier plate, a supporting plate, a screening box, a lifting part, strip ports, a screen mesh, material guiding grooves, a filling assembly and a metal corrugated compensator. The screening box is supported by the lifting part and the supporting plate, without affecting the ammonia synthesis catalyst falling into a material storage bin, the screening box rotates around the supportingplate by controlling the length of the lifting part, thus a tilt angle of the screening box is adjusted according to the needs, the ammonia synthesis catalyst is screened through the screen mesh in the screening box, two parts of the screened ammonia synthesis catalyst correspondingly slide into the two material guiding grooves through the two strip ports, then the ammonia synthesis catalyst sliding into the material guiding grooves falls into the filling assembly through the metal corrugated compensator, the filling assembly discharges the ammonia synthesis catalyst to a filling container below a filling pipe, the integration of screening and filling is achieved, the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an ammonia synthesis catalyst preparation, screening and filling device, which belongs to the technical field of catalyst production. Background technique [0002] Ammonia synthesis catalyst is a catalyst used in high-pressure, high-temperature ammonia synthesis reaction, including iron-based and non-iron-based. Ammonia synthesis catalyst can be regarded as the heart of the entire ammonia synthesis plant. Before filling the ammonia synthesis catalyst, ammonia synthesis catalysts of different sizes need to be screened, and then filled after screening. The screening and filling are carried out separately, which not only affects the work efficiency, but also causes high labor intensity due to frequent material transfer. . Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a screening and filling device for preparing ammonia synthesis catalysts to s...
