Abstract

The invention provides a spray lance device and a ladle lining refractory jet device, relates to the technical field of refractory jet equipment, and solves the technical problems of high labor intensity and low construction efficiency existing in the prior art. The spray lance device comprises a support box, a spray gun drive device and a rotary spray gun, the rotary spray gun comprises a gas-liquid rotary joint and a nozzle, the nozzle is connected to a refractory pipeline through the gas-liquid rotary joint, and the gas-liquid rotary joint and the nozzle can rotate relative to the refractory pipe. The ladle lining refractory jet device comprises the refractory pipeline, a compressed air pipeline, a quick-setting agent pipeline, the spray gun device, a lifting device and a control device. The jet direction of the spray gun device can be freely adjusted, the labor intensity is reduced, and the jet efficiency is improved; a lifting body and the spray gun device are controlled by the control device, and multiple injection modes of point jet, area jet and automatic circulation jet are realized.

Description

technical field [0001] The invention relates to the technical field of refractory material injection equipment, in particular to a spray gun device and a ladle lining refractory material injection device. Background technique [0002] At present, semi-dry injection and wet injection are mostly used for injection of blast furnace lining refractory materials, and most of the existing equipment for wet injection of refractory materials requires manual control of the nozzle during use. During the process, it is difficult to adjust the angle and height of the nozzle, not only the labor intensity is high, the construction environment is harsh, but also the injection quality is poor, and the construction efficiency is low. [0003] A refractory material gunning machine for the inner wall of a kiln disclosed in Chinese patent documents, the gunning machine is composed of a conical tank body, a feed inlet and a spray gun tube, and the discharge port of the conical tank body is sequen...
