Online thermal state remote control automatic spraying device for industrial furnace refractory material lining

Abstract

The invention relates to a spraying device for an industrial furnace refractory material lining, and provides an online thermal state remote control automatic spraying device for an industrial furnace refractory material lining. The automatic spraying device comprises a cylindrical shell, a center shaft, a hydraulic motor, a rotary joint, a set of spray gun and balance weight telescoping device, a material pipe joint flange and a material pipe, wherein one end of the cylindrical shell is open; the center shaft is provided with a shaft sleeve and penetrates through the closed end of the shell, the end of the center shaft is provided with a refractory material inlet, and the side face of the center shaft is provided with a set of hydraulic oil inlet and outlets and auxiliary material inlets; the hydraulic motor is arranged inside the shell; an output shaft of the hydraulic motor drives the center shaft to rotate through a transmission gear; the rotary joint is arranged on the side, close to the opening of the shell, of the center shaft; the set of spray gun and balance weight telescoping device comprises two hydraulic cylinders and two telescopic pipes, the two hydraulic cylinders and the two telescopic pipes are installed on the two side faces of the lower portion of the center shaft respectively, and the telescopic pipes are driven by the hydraulic cylinders to stretch out and draw back, are perpendicular to the center shaft and rotate along with the center shaft; the material pipe joint flange is vertically communicated with the center shaft; the material pipe is arranged inside the center shaft and connected with one end of the center shaft through the material pipe flange. The automatic spraying device can reduce labor cost of spraying and operation safety.

Description

technical field [0001] The invention relates to an industrial kiln refractory lining, in particular to an automatic spraying device for an industrial kiln refractory lining. Background technique [0002] Due to the continuous improvement of spraying quality requirements in the industry, the variety of domestic furnace types and serious aging, and the large increase in blast furnace overhaul projects, wet spraying has the characteristics of low rebound rate and fast construction speed. Wet spraying technology is constantly being used. Adoption; at this stage, the wet spraying method we use is artificial spraying. In the case of increasingly fierce competition, artificial spraying can no longer meet the requirements of the market, and the labor cost continues to increase. Artificial wet spraying has been greatly affect the economic benefits of the project. Contents of the invention [0003] The invention aims to solve the above-mentioned defects in the prior art, and provid...
