A preheating and surfacing device for wear-resistant layer of limestone crushing roller

Abstract

The invention discloses a preheating and surfacing device for a wear-resistant layer of a limestone crushing roller. The preheating and surfacing device comprises two surfacing rotary supporting rollers, a wear-resistant layer surfacing welding gun, a surfacing welding powder spray pipe and a surfacing preheating arc-shaped cover plate, wherein the two surfacing rotary supporting rollers are arranged at the bottom of the crushing roller with the axis horizontally placed, the wear-resistant layer surfacing welding gun and the surfacing welding powder spray pipe are arranged above the top surface of the crushing roller, and the surfacing preheating arc-shaped cover plate is arranged on the roller surface of the crushing roller and is located on one side of the wear-resistant layer surfacing welding gun; the axes of the two surfacing rotary supporting rollers are all horizontal and are parallel to the axis of the crushing roller; the two surfacing rotary supporting rollers are symmetrically arranged relative to the vertical plane of the axis of the crushing roller; surfacing preheating heating blocks are arranged between the surfacing preheating arc-shaped cover plate and the roller surface of the crushing roller; and the surfacing welding powder spray pipe is located between the surfacing preheating arc-shaped cover plate and the wear-resistant layer surfacing welding gun. According to the preheating and surfacing device, the preheating and surfacing operation of the crushing roller can be continuously completed on one device, and therefore the labor intensity of operators can be reduced, and the production safety can be improved.

Description

technical field [0001] The invention relates to the technical field of cement production process equipment, in particular to a preheating and surfacing device for a wear-resistant layer of a limestone crushing roller. Background technique [0002] Limestone is one of the important components of cement raw materials. Limestone needs to be crushed before being mixed with other cement raw materials. The long-term working surface of the crushing roller for crushing limestone is easy to wear. Grinding layer to increase the surface wear resistance of the crushing roll and the service life of the crushing roll. The wear-resistant layer on the surface of the crushing roller usually needs to be preheated before surfacing, and the surface of the crushing roller is heated to a certain temperature before the surfacing operation is performed to ensure the quality of the wear-resistant layer surfacing. The preheating of conventional limestone crushing rollers is mainly carried out by man...

AI Technical Summary

Problems solved by technology

The preheating of conventional limestone crushing rollers is mainly carried out by manually assisting surfacing equipment. Due to the large volume and weight of limestone crushing rollers, there are certain safety hazards in preheating crushing rollers near surfacing equipment. It is necessary Design a fully mechanically operated limestone crushing roller wear-resistant layer preheating surfacing device, thereby reducing the labor intensity of operators and production safety
