Abstract

The invention provides a sealing device of a wet type ball grinder head section in a thermal plant. The sealing device comprises sealing packing, a clamping apparatus, a radial locking device and an axial compressing device, wherein the sealing packing is fixed at the joint of the grinder head section and an inlet tube; the clamping apparatus is used for fixing and compressing the outside of the sealing packing; the radial locking device is used for locking the clamping apparatus; and the axial compressing device is used for fixing the inlet tube and compressing the clamping apparatus. According to the sealing device of the wet type ball grinder head section in the thermal plant provided by the invention, the joint face of the sealing packing and the ball grinder can be adjusted regularly, and mortar leakage at the inlet of the ball grinder is effectively prevented, so that the overhaul maintenance quantity is reduced.

Description

technical field [0001] The invention relates to the technical field of wet ball mills, in particular to a sealing device for a head of a wet ball mill in a thermal power plant. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is composed of feeding part, discharging part, rotary part, transmission part and other main parts. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics, etc., for dry or wet grinding of various ores and other grindable materials. [0003] At present, thermal power plants are basically equipped with flue gas desulfurization devices, and limestone mills are the most important equipment in the slurry preparation system. There are two commonly used limestone grinding schemes: dry grinding and wet grinding, with wet grinding as the main type, and horizontal...
