Abstract

The invention relates to the technical field of temperature measurement of rotary kilns and provides a self-driven type direct temperature measurement device for a rotary kiln. The device comprises a rotating driving motor, screw rods, a thermocouple and a sleeve pipe, wherein the rotating driving motor drives the screw rods to rotate; the sleeve pipe is fixedly arranged on the outer side of the thermocouple in a sleeving manner and extends into a temperature measurement through hole formed in the side wall of the rotary kiln; screw grooves matched with threads of the screw rods are formed in the outer surface of the sleeve pipe; and the sleeve pipe is driven by the screw rods to drive the thermocouple to reciprocate periodically in the axial direction of the temperature measurement through hole. According to the device, the thermocouple is driven by the sleeve pipe to move, so that materials entering the temperature measurement through hole are cleared automatically, the temperature measurement through hole is prevented from being blocked by material beads, and the service life and the temperature measurement precision of the thermocouple are guaranteed.

Description

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