Abstract

The invention relates to field installation of a chemical reaction container with a stirring device, in particular to a stirring device connecting flange grinding tool and method. The tool comprises a grinding disc, a supporting disc and a fixing and adjusting fastener, wherein the grinding disc comprises a central shaft, a grinding ring and four handles. The supporting disc comprises a supporting ring, a locking disc, a locking bolt, a bearing pedestal, a bearing, a bearing cover and a sunk screw. The fixing and adjusting fastener comprises four studs, four positioning semi-rings, eight fixing nuts and four adjusting nuts, wherein the positioning semi-rings are welded on the studs. According to the tool and the method, the levelness alignment of the sealing surface of the top flange does not need to sacrifice the equipment mounting perpendicularity precision, that is, the levelness is adjusted after the perpendicularity precision requirement is strictly ensured; and the equipment installation precision is integrally improved, the design intention is met to the maximum extent, the use function requirements are met, and guarantee is provided for long-period operation of equipment, equipment internals and a stirring device.

Description

technical field [0001] The invention relates to on-site installation of a chemical reaction vessel with a stirring device, in particular to a grinding tool and method for connecting a stirring device to a flange. Background technique [0002] The chemical reaction vessel is installed with a vertical mixer. The levelness of the top flange of the reaction vessel is high. The levelness of the top flange must be guaranteed to be 0.10-0.15mm. The levelness of the top flange directly affects the swing of the stirring shaft. , for large-scale chemical reaction equipment, the sealing surface of the top flange cannot be reprocessed after the overall production of the equipment is completed. The secondary deviation is caused, and the elimination of the secondary deviation mainly depends on sacrificing the verticality accuracy requirements of the equipment, that is, adjusting the levelness deviation of the top flange within the allowable deviation range of the verticality, so that it c...
