Problems solved by technology

[0006] The disadvantages of the direct temperature measurement method of the rotary kiln are: it is easy to enter the high-temperature powdery material in the temperature measurement through hole, and the semi-molten material is easy to adhere. Once it enters the hole, it will be difficult to pour it out, and it will form a lump Block the temperature measurement through hole, thereby greatly reducing the temperature measurement accuracy
[0008] The shortcomings of the indirect temperature measurement method of the rotary kiln are: poor measurement accuracy, slow response speed, difficult to meet the process requirements, and easily affected by ring formation or lining peeling

Abstract

The invention relates to the technical field of temperature measurement of rotary kilns, and provides a self-driven direct temperature measurement device for a rotary kiln. The self-driven direct temperature measurement device for the rotary kiln comprises a rotary driving motor, a screw rod, a fixed installation base, a thermoelectric couple and a sleeve pipe. The rotary driving motor, the screw rod and the thermoelectric couple are mounted on the fixed installation base, and the fixed installation base is fixed to the side wall of the rotary kiln. The rotary driving motor drives the screw rod to rotate. The sleeve pipe is arranged outside the thermoelectric couple in a sleeving mode and stretches into a temperature measurement through hole formed in the side wall of the rotary kiln. A screw groove in threaded fit with the screw rod is formed in the outer surface of the sleeve pipe. The sleeve pipe is driven by the screw rod to reciprocate periodically in the axial direction of the temperature measurement through hole. According to the self-driven direct temperature measurement device for the rotary kiln, materials entering the temperature measurement through hole are removed automatically through movement of the sleeve pipe, the temperature measurement through hole is prevented from being blocked by material lumps, and thus the service life and temperature measurement precision of the thermoelectric couple are guaranteed.

Description

technical field [0001] The invention relates to the technical field of temperature measurement of a rotary kiln, in particular to a self-driven direct temperature measurement device for a rotary kiln. Background technique [0002] Rotary kilns are widely used in various industries. For example, in many production industries such as building materials, metallurgy, chemical industry, and environmental protection, rotary kilns are used for mechanical, physical or chemical treatment of solid materials. Specifically: First, in non-ferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, files and other metals use rotary kilns as smelting equipment to sinter ores, concentrates, intermediates, etc. Roasting. Among them, the rotary kiln is used to roast aluminum hydroxide into alumina in aluminum production; the rotary kiln is used to produce pellets for blast furnace ironmaking in ironmaking; the foreign SL / RN method and Krupp method use rotar...
