Online repairing structure of double-shaft humidifying stirrer of dust remover

Abstract

The utility model discloses an online repairing structure of a double-shaft humidifying stirrer of a dust remover, belongs to the technical field of dust remover stirrer equipment, and is used for repairing the double-shaft humidifying stirrer. According to the technical scheme, an adjusting top plate is vertically welded to the upper surface of a box body bottom plate on the outer side of the rear end of a driven shaft, a lead screw hole is formed in the adjusting top plate, and an adjusting lead screw is screwed in the lead screw hole; when the easily-broken part of the driving shaft is broken, a dummy shaft for repairing is arranged, one end of the driving shaft is matched with the shaft device and the bearing, the end face of the other end is of a sleeve structure, and the maintenance end of the driving shaft is embedded in the end face sleeve of the dummy shaft and fixedly connected; after the blades are abraded, maintenance blades are additionally arranged and are arc-shaped manganese steel plates, the lower ends of the maintenance blades are welded to the upper ends of the abraded blades, and the tool bits are installed on the maintenance blades through fixing bolts. The online repairing structure is simple in structure and convenient to use, the problems of blade clamping, driving shaft breaking and blade abrasion caused by gear abrasion or gear tooth abutting and offside can be rapidly solved, the maintenance time is greatly saved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a double-shaft humidifying mixer for a dust removal system of a dust collector, and belongs to the technical field of dust collector mixer equipment. Background technique [0002] At present, the double-shaft humidifying mixer is widely used in the dry dust removal and ash removal system with small density and fine particles in the iron and steel complex, and the blast furnace purification dust collection and ash removal system. The twin-shaft mixer has the advantages of compact structure, small footprint, stable transmission, low noise, uniform mixing, and reliable operation. , transported by car to a centralized mixing site for recycling, effectively avoiding the phenomenon of dust in the process of loading and transporting dust, and meeting the requirements of environmental protection for outbound transportation. However, in use, it is found that the current twin-shaft mixer is prone to the following three difficult-to-hand...

Problems solved by technology

The current treatment method is that if any break occurs during use, the normal use of the equipment is generally restored by replacing the new humidifier as a whole, but often the rest of the humidifier system is relatively good, and the overall replacement of the humidifier causes a certain degree of waste

[0005] (3) After the cutter head fixed on the upper part of the blade in the box was worn out, it was not replaced in time, which caused the blade to be evenly ground down by about 30mm-40mm along the height direction, resulting in poor ash transportation, poor humidification effect of dry ash, and serious dust emission , while the thickness of the blade is still qualified, and the welding between the lower part of the blade and the surface of the shaft is still very firm

The treatment method is generally to cut off the worn blades, weld new blades, and then install and fix the cutter head, which is time-consuming and laborious, resulting in a certain degree of waste of spare parts cost

[0006] In view of the above-mentioned difficult-to-handle failures in the existing dual-axis humidifiers, it is very necessary to improve the existing dual-axis humidifiers to achieve the purpose of repairing them quickly and conveniently
