Abstract
A material temperature detector for rotary kiln, can clean thermocouple and its protection casing surface kiln crust, avoid abrasion of the thermocouple, and automatically collect and replace the detected material samples. The detector locates the thermocouple in the protection casing, and comprises a fireresistant frame bigger than the protection casing and including an open chamber. The protection casing is located in the chamber, and a reciprocating-moving cleaning device is located between the inside surface of the chamber and the outside surface of the protection casing, and connects to the protection casing. When the rotary kiln rotates, the being-detected material falls into the open of the chamber, and slides by gravity in the chamber. The clean device moves to the material in the chamber by driven component, and clean the protection casing and the chamber by the movement.
Description
Affiliated technical field
The present invention relates to a kind of temperature measuring equipment, especially relate to a kind of protective casing surface kliner coating that is applicable to temperature of charge measurement in the rotary kiln, can cleans thermopair, can avoid thermopair to wear and tear, can gather automatically and change the interior temperature of charge detecting device of rotary kiln of tested material sample.
Background technology
At present, the temperature of charge detection technique is in the known rotary kiln: thermopair is placed in the protective casing, penetrate from cylinder of rotary kiln steel plate opening, be installed in the cave or pouch that the kiln lining inside surface of rotary kiln is provided with, or be installed in the inner space of rotary kiln.Owing to have a large amount of dung in the rotary kiln, dung can be built up in the cave or in the pouch gradually, forms kliner coating, and final thermopair and the protective casing thereof that is installed in cave or the pouch that cover, kliner coating can hinder the heat energy thermoelectric couple conduction of tested material, causes the temperature survey poor effect; Be installed in the thermopair and the protective casing thereof of rotary kiln inner space, be subjected to the friction that high-temperature material rolls in the rotary kiln, make the protective casing wearing and tearing so that damage, the thermopair breaking-up that is worn subsequently, very fast ineffective." 829 pages to 830 pages of cement works teacher handbook, Wang Lan writes, Chinese building material industry publishing house, book number ISBN7-800900-428-8 to see reference for details
Summary of the invention
Be installed in the cave of rotary kiln liner inside surface setting or the pouch and covered in order to overcome existing thermopair and protective casing thereof by kliner coating; cause the thermometric poor effect; or be installed in the major defect that the thermopair of rotary kiln inner space and protective casing thereof are rubbed and damage; the invention provides temperature of charge detecting device in a kind of rotary kiln; the temperature of charge detecting device not only can clean protective casing surface and kliner coating on every side in this rotary kiln; make the direct contact protection sleeve pipe of material; improve temperature detecting precision; and can make thermopair and protective casing thereof avoid the friction of material in the kiln; prolong thermopair serviceable life; and can clocklike gather automatically and change the tested material sample, make detection means be tending towards reasonable more.
The technical solution adopted for the present invention to solve the technical problems is: thermopair places in the protective casing, be provided with one greater than protective casing and the high-temperature resistant shell of an open cavity is arranged, protective casing is placed in one and is connected as a single entity, leave the space between the inwall of high-temperature resistant shell cavity and the protective casing outside surface with it; In this space; a clearing apparatus that can move back and forth is set, and an end of clearing apparatus can contact with the material in the rotary kiln, and the other end is connected with a driven unit; the facade of clearing apparatus contacts with the outer facade of protective casing with the inwall facade of cavity simultaneously, and leaves the gap.In the rotary kiln rotation, when temperature of charge detecting device in the rotary kiln that is installed between cylinder of rotary kiln steel plate and the kiln lining inside surface is about to be in the rotary kiln below, driven unit pulls to driven unit one end with clearing apparatus, make the space that forms a upward opening between protective casing outside surface and the cavity inner wall, tested material in the rotary kiln falls under gravity into cavity, directly contact with protective casing, help the heat energy thermoelectric couple conduction of tested material; Employing can prolong tested material stationing the time in cavity with the setting angle that high-temperature resistant shell axis and rotary kiln liner inside surface tangent to periphery coincide, and has effectively prolonged the duration of contact of tested material and protective casing; Along with being rotated further of rotary kiln, the angle of high-temperature resistant shell axis also changes thereupon gradually, tested material is being brought in the cavity above the rotary kiln, when temperature of charge detecting device in the rotary kiln is crossed the top and is begun to rotate towards the below, temperature of charge detecting device cavity changes into gradually under shed in the rotary kiln, and tested material begins from the cavity landing under action of gravity.Then clearing apparatus under the driving of driven unit in rotary kiln the material direction move, this mobile itself both formed the cleaning to protective casing outside surface and cavity, formed the thorough replacing to tested material again.Along with the continuous rotation of rotary kiln, the axis of high-temperature resistant shell constantly changes angle, and the opening of cavity also constantly clocklike changes towards, work the carrying out of going round and beginning again of cleaning kliner coating, collection and replacing tested material.
The invention has the beneficial effects as follows: can clean protective casing outside surface kliner coating and cavity kliner coating, tested material is directly contacted with protective casing, help the conduction of tested material heat energy thermoelectric couple, measure more direct; Owing to adopt the setting angle that high-temperature resistant shell axis and rotary kiln liner inside surface tangent to periphery are coincided, thereby prolonged tested material stationing the time in cavity, effectively prolonged the duration of contact of tested material and protective casing, can improve accuracy of detection the tested material temperature; Because protective casing is installed in the high-temperature resistant shell cavity and with it and is connected as a single entity, thereby can avoid the interior material of kiln to roll, can increase the rupture strength of protective casing, prolong the serviceable life of thermopair the friction and the impact of thermopair and protective casing thereof; Follow the continuous rotation of rotary kiln, the high-temperature resistant shell axis constantly changes angle, the opening of cavity constantly clocklike change towards, thereby can clocklike gather automatically and change the tested material sample, make detection means be tending towards reasonable more.
