Automatic temperature control drying kiln for desulfurization spray gun

Abstract

The invention belongs to the field of a drying plant, in particular to an automatic temperature control drying kiln for a desulfurization spray gun for the metallurgy industry. The drying kiln comprises a kiln body and a temperature control device, wherein the kiln body comprises a kiln wall (1), a kiln gate (2) and a kiln cover (7); a spray gun rack (3) is fixedly arranged in the kiln body; a heater (4) is fixedly arranged on the kiln wall (1) which comprises a red brick layer (5) and a refractory brick layer (6) connected with the red brick layer (5); the kiln gate (2) or the kiln cover (7) comprises a metal layer (8) and an insulating cotton layer (9) connected with the metal layer (8); the temperature control device comprises a temperature sensor arranged in the kiln body and an external control device; the transmission port of the temperature sensor is connected with the transmission port of the external control device; and the port of the heater (4) is connected with the port of the external control device. The drying kiln has simple structure, consumes less energy and can realize automatic temperature control.

Description

technical field [0001] The invention belongs to the field of drying equipment, in particular to a drying kiln with an automatic temperature-controlling desulfurization spray gun used in the metallurgical industry. Background technique [0002] The desulfurization spray gun is a consumable spare part with a high price, and its life is directly related to the cost of the pretreatment process. Therefore, it is an important measure to reduce the cost of desulfurization to extend the life of the spray gun. [0003] The outside of the gun body of the desulfurization spray gun is attached with a layer of refractory material. In the manufacturing process of the refractory material layer, because the raw materials contain a large amount of water, the method of heating and drying is usually used to remove the water in the refractory material to meet the specified standards. In the past, when the desulfurization spray gun was heated and dried, the manual and extensive baking mode wit...

AI Technical Summary

Problems solved by technology

In the past, when the desulfurization spray gun was heated and dried, most of them used the manual and extensive baking mode that consumes a lot of energy.

This mode lacks reasonable temperature control, which easily leads to insufficient homogeneity of the refractory material layer, which leads to the occurrence of hidden defects such as looseness and cracking in local areas
