Novel combustion furnace for drying drum

Abstract

The invention relates to a novel combustion furnace for a drying drum. The novel combustion furnace comprises a suction pipeline, a conveying fan, a delivery pipeline, a feeding burner, a furnace bottom fan, an automatic control system and a combustion furnace body, wherein the automatic control system comprises a thermocouple, a PLC control center and a temperature controller; the suction pipeline is matched and connected with the delivery pipeline through the conveying fan; the thermocouple is matched with and arranged on an air outlet of the combustion furnace body; the feeding burner is matched with and arranged on a feeding hole of the combustion furnace body; the PLC control center is arranged outside the combustion furnace body and is respectively matched and connected with the conveying fan and the furnace bottom fan through circuits; and the temperature controller is arranged outside the combustion furnace body and is matched and connected with the PLC control center, and the thermocouple is matched and connected with the PLC control center through the temperature controller. The novel combustion furnace can be automatically controlled and can be used for reducing the labor intensity, improving the working environment and avoiding safety production accidents.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a new type of combustion furnace suitable for drying drums. Background technique [0002] The drum dryer mainly includes a drum, which is a cylinder slightly inclined to the horizontal direction. The material is fed from the higher end, and the high-temperature hot flue gas and the material flow into the cylinder. With the rotation of the cylinder, the material is The effect of gravity runs to the lower end. The dried product is collected from the lower part of the bottom end. The combustion furnace provides a high-temperature heat source to the drum, and the raw coal powder or other substances enter the combustion furnace through the fan and the conveying pipe for full combustion, and then transport the high-temperature hot flue gas into the drum for the drying of the materials to be dried in the drum. drying.

AI Technical Summary

Problems solved by technology

[0003] At present, in the light fuel drying industry, most of the equipment that provides heat sources are manually operated, especially coal furnaces, from the control and adjustment of fuel addition temperature to the discharge and treatment of slag, etc., all links need manual operation Completion leads to poor working environment, high labor intensity, and high incidence of burns and scalds. For safe and civilized production, the requirements for reducing labor intensity and improving labor efficiency have become a huge test. Correspondingly, higher requirements have been put forward for intelligence and automation.
