Abstract
The utility model discloses a device for detecting temperature in a rotary kiln. The device is characterized in that a rotary kiln cylinder body (1) is provided with a through hole, the through hole is provided with a protection sleeve (2) which stretches into the inner part of the rotary kiln cylinder body and is made by adopting anti-oxidation heat-resisting steel, and a thermocouple (3) is inserted in the protection sleeve from outside to inside. The device disclosed by the utility model has the advantages that the structure is simple, the device can be prevented from being broken by a lump, and the service life can be effectively prolonged.
Description
Technical field
The utility model relates to temperature measuring apparatus in a kind of rotary kiln, and it plays the mechanical protection effect to the thermocouple of measuring kiln temperature.
Background technology
Kiln temperature is one of rotary kiln important technical parameter, and its mensuration and transmission key device are mounted in the thermocouple on the cylinder of rotary kiln.Commercial thermocouple assembly generally has duplex sheath: nexine is porcelain bushing, and skin is the stainless steel sleeve pipe, and stainless steel tube thickness generally only has 1-2mm.Because rotary kiln unavoidably can produce the blocks such as blast pipe of the kiln ramming material of bulk, the refractory brick that drops or fracture when work, these blocks can rotate with material in rotary kiln, when running into thermocouple and stretch into rotary kiln inner sheath part, because thermocouple well is too small, large block can sever thermocouple well, causes thermocouple to be scrapped.
Summary of the invention
The purpose of this utility model provides the interior temperature measuring apparatus of a kind of rotary kiln simple in structure, long service life.
Temperature measuring apparatus in a kind of rotary kiln that the utility model provides; it is to have a through hole at cylinder of rotary kiln; install one on the through hole and stretch into protective sleeve cylinder of rotary kiln inside, that adopt oxidation-resistant heat-resistant steel to make, protective sleeve is plugged with thermocouple from outside to inside.
This protective sleeve stretches into the inner end sealing of cylinder of rotary kiln inside, and the outer end is welded on the cylinder of rotary kiln, the wall thickness 10～15mm of this protective sleeve.
The utlity model has following advantage:
Can prevent effectively that the thermocouple in the temperature measuring apparatus from being severed by block, effectively increase the service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1; temperature measuring apparatus in a kind of rotary kiln that the utility model provides; it is to have a through hole at cylinder of rotary kiln 1, installs one on the through hole and stretches into protective sleeve 2 cylinder of rotary kiln inside, that adopt oxidation-resistant heat-resistant steel to make, and protective sleeve 2 is plugged with thermocouple 3 from outside to inside.This protective sleeve 2 stretches into the inner end sealing of cylinder of rotary kiln inside, and the outer end is welded on the cylinder of rotary kiln 1, the wall thickness 12mm of this protective sleeve 2.Because protective sleeve 2 adopts oxidation-resistant heat-resistant steel to make, and has enough intensity, even run into the blocks such as blast pipe of the kiln ramming material of bulk, the refractory brick that drops or fracture, also can protect thermocouple not to be damaged.
Claims (3)
1. temperature measuring apparatus in the rotary kiln; it is characterized in that; it is to have a through hole at cylinder of rotary kiln (1); install one on the through hole and stretch into protective sleeve (2) cylinder of rotary kiln inside, that adopt oxidation-resistant heat-resistant steel to make, protective sleeve (2) is plugged with thermocouple (3) from outside to inside.
2. temperature measuring apparatus in a kind of rotary kiln according to claim 1 is characterized in that, this protective sleeve (2) stretches into the inner end sealing of cylinder of rotary kiln inside, and the outer end is welded on the cylinder of rotary kiln (1).
3. temperature measuring apparatus in a kind of rotary kiln according to claim 1 and 2 is characterized in that the wall thickness 10～15mm of this protective sleeve (2).
