Removing device for ringed waste residue in rotary kiln

Abstract

The invention belongs to the technical field of metallurgical production equipment, and particularly relates to a removing device for ringed waste residue in a rotary kin. The removing device is cooled with cooling water. A pipe surface cooling device is fixed to a mechanical arm through a bracket. The mechanical arm is fixed to riding wheels through pinch rollers. Reduction gears driven by a speed reducer do reciprocal rectilinear motion. A cooling water pipe is arranged in the mechanical arm, and is connected with the pipe surface cooling device at the rear part of a front-end relieving tool. The front-end relieving tool is arranged at the front end of the mechanical arm, and is fixedly connected with the mechanical arm through a relieving tool post. A motion scraper is arranged on the front-end relieving tool. The ringed waste residue in the rotary kiln, cut off by the front-end relieving tool, is removed by the motion scraper. The removing device has the beneficial effects of being convenient to mount and use, good in cooling effect, and low in possibility of device burnout. The mechanical arm is not liable to be bent and deformed, and the waste residue is easily removed.

Description

Technical field [0001] The invention belongs to the technical field of metallurgical production equipment, and specifically relates to a ring-removing device in a rotary kiln. Background technique [0002] Rotary kiln refers to rotary calcining kiln, commonly known as rotary kiln, which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. In the calcination production process, ring formation at the end of the rotary kiln has a greater impact on the stability of the production status of the rotary kiln, such as the decrease of the temperature in the rotary kiln, the increase of powdery materials in the sedimentation chamber, and the overflow of petroleum coke materials at the tail. Specifically speaking, the existence of the ring has the following four effects: one is the ventilation in the kiln, the increase of CO concentration in the flue gas will accelerate...

AI Technical Summary

Problems solved by technology

The existing equipment of this type of equipment is bulky, immovable, and controlled by the installation site; the trolley is driven by a slow rack and pinion, and the mechanical arm is bent and deformed due to the long time of scraping in the kiln.

The scraper of the existing equipment cannot be adjusted accordingly according to the amount of slag removal. When encountering uneven accumulation, the mechanical arm is over-pressed and bent, causing the trolley frame to deform accordingly; the cooling water is introduced from the pull arm to the scraper, and the mechanical arm Burned out due to lack of water cooling in the tube
