Problems solved by technology

During the production process, due to various reasons, the refractory material layer in the drying kiln will fall off in a small area. If the refractory material is not repaired in time, the falling off will be accelerated, and the falling area (depth) will expand, causing damage to the drying kiln body. In this way, the drying kiln must Flame out and stop production for repair, affecting the production of pellets

Embodiment 1

[0011] Under the condition that the drying kiln is not turned off and the production is stopped, reduce the temperature inside the drying kiln body to 80°C, and directly repair the refractory material layer to be repaired by the slurry gunning machine. The repaired area is 0.1 square meters and it takes 15 minutes.

Embodiment 2

[0013] Under the condition that the drying kiln is not turned off and the production is stopped, reduce the temperature inside the drying kiln body to 100°C, and directly repair the refractory material layer to be repaired by the slurry gunning machine. The repaired area is 0.13 square meters and it takes 20 minutes.

Embodiment 3

[0015] Under the condition that the drying kiln does not shut down and stop production, reduce the temperature inside the drying kiln body to 170°C, and directly repair the refractory material layer to be repaired by the slurry gunning machine. The repaired area is 0.15 square meters and it takes 24 minutes.

Abstract

The invention relates to the technical field of dry kilns, in particular to a dry kiln refractory material layer repairing method. The method comprises the steps that under the condition of no flameout of a dry kiln, the internal temperature of a kiln body of the drying kiln is reduced to 80-170 DEG C; a slurry gunning machine is used for directly repairing a refractory material layer to be repaired, the repaired area is less than 0.15 square meter, and sprayed slurry can be quickly solidified under the high-temperature conditions and can repair the refractory material layer to be repaired intime to prevent the refractory material layer from further falling off and affecting production of the dry kiln. Through the repairing method, the repairing effect is good, production of the dry kilncannot be affected, and the service life of the dry kiln is prolonged.

Description

technical field [0001] The invention relates to the technical field of drying kilns, in particular to a method for repairing a refractory material layer of a drying kiln. Background technique [0002] At present, in the pelletizing industry, drying kilns are generally used to burn pellets. During the production process, due to various reasons, the refractory material layer in the drying kiln will fall off in a small area. If the refractory material is not repaired in time, the falling off will be accelerated, and the falling area (depth) will expand, causing damage to the drying kiln body. In this way, the drying kiln must Flame out and stop production for repair, affecting the production of pellets. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for repairing the refractory layer of a dry kiln with high timeliness and good effect. [0004] The method for repairing the refractory material layer of the...
