Abstract
The invention relates to a sintering kiln temperature-measuring thermocouple protection device which comprises a sintering kiln, wherein a temperature-measuring thermocouple is arranged on the inner kiln wall of the sintering kiln, a protection device body is arranged around the temperature-measuring thermocouple and is formed by refractory bricks arranged on the left side and right side of the temperature-measuring thermocouple and above the temperature-measuring thermocouple. The sintering kiln temperature-measuring thermocouple protection device is ingenious in concept, and the temperature-measuring thermocouple can be protected against breakage and bumping damage by a dropped-out ceramic roller bar only by building several refractory bricks around the temperature-measuring thermocouple during kiln wall construction. Several refractory bricks are increased, the manufacturing cost is almost not increased, the replacement and maintenance frequency of the temperature-measuring thermocouple is reduced, production order is guaranteed, and production efficiency is improved.
Description
Technical field
The invention belongs to ceramic rod production field is and in particular to a kind of sintering oven temperature thermocouple protection device.
Background technology
Ceramic rod refers to wait through selected, pulverizing, shaping, calcining with natural mineral raw with clayey refractory raw material
Journey and the refractory product made.Ceramic rod is applied to the roller kilns in glass ceramics industry.Ceramic rod is as a kind of fire resisting
Kiln furnitures, play the effect of support, transmission ceramic body and product in roller-way calcining kiln and roller way drying kiln, are the cores of roller kilns
Part, it is the energy-conservation of roller kilns, shorten firing period and automatic operation is made that significant contribution, construction sanitary ceramic,
It is used widely in the fields such as domestic ceramics, electronic ceramics, magnetic material, glass heat treatment, wear resistant appliance.At present, roller kilns
Stove develop to Wide Band Oxygen Sensors, operation at high temperature direction it is desirable to ceramic rod at high temperature, intensity is high, and can continuously run；Certainly
Under the load effect of weight and product, can keep indeformable.And the field such as daily, sanitary ware and magnetic material, to ceramic rod
High-temperature behavior require higher.
The processing technology of ceramic rod is that pug is pressed into filter cake through pressure filter, is then passed through vacuum deairing machine, vacuum is squeezed
Go out machine molding, then adopt suspension type high temperature sintering, the sintering temperature of ceramic rod, typically more than 1500 DEG C, needs to use thermometric
The temperature of thermocouple close supervision sintering kiln.Mostly after existing ceramic rod forming and sintering is single-layer tubular structure, and roller rod is negative
Loading capability is poor, and increasing wall thickness is to improve the commonly used method of roller rod intensity at present, and the method can play to a certain extent
Increase the effect of roller rod intensity, but the increase of wall thickness result in the increase of roller rod own wt, on the one hand can increase roller rod
Production cost, on the other hand, the increasing of wall thickness can lead to the heat stability of roller rod to reduce, heat-sinking capability variation, amasss at high temperature
Gather the heat in club can not distribute in time and produce internal stress, make the inside and outside contraction of roller rod inconsistent, be easily caused roller rod
Crack and then burst, in addition easily ruptured at the mouth hanging of end using roller rod during suspension type high temperature sintering and drop, roller rod
Blast or fracture are dropped, be poured on kiln wall easily by the temperature thermocouple being located on kiln wall pound disconnected so that the temperature in kiln no
Method measures, and has a strong impact on production.
Content of the invention
It is an object of the invention to provide a kind of protection device of ceramic rod sintering oven temperature thermocouple, prevent thermometric thermoelectricity
The roller rod being occasionally dropped is pounded disconnected or is broken, and ensures to produce and stablizes.
The present invention employs the following technical solutions and is attained in that sintering oven temperature thermocouple protection device, including sintering
Kiln, in described sintering oven, kiln wall is provided with temperature thermocouple, arranges protection device around temperature thermocouple.
Described protection device is to be arranged on the arranged on left and right sides of temperature thermocouple and the refractory brick of top.
Described refractory brick is apart from temperature thermocouple 8-15cm.
Laying fireproof bricks are in kiln within the walls.
Temperature thermocouple stretches out kiln wall 10-12cm, and refractory brick stretches out kiln wall 5-10cm.
The described sintering oven left and right sides is kiln wall, and both sides are wicket in front and back.
The present invention relates to being skillfully constructed, only several blocks of refractory brick need to be built around temperature thermocouple by laying bricks or stones when Yao Qiang builds by laying bricks or stones, just
The ceramic rod that temperature thermocouple is not dropped can be protected to pound disconnected breaking；Increase several blocks of refractory brick, hardly increase kiln system
Cause this, reduce the repair and replacement frequency of temperature thermocouple, ensured the production order, improve production efficiency.
Brief description
Fig. 1 is present configuration schematic diagram.
Specific embodiment
As shown in figure 1, sintering oven temperature thermocouple protection device, including sintering oven 1, the sintering oven left and right sides is kiln wall,
Both sides are wicket in front and back, and in described sintering oven, the kiln wall of the left and right sides is provided with temperature thermocouple 2, around temperature thermocouple 2
Setting protection device, described protection device is to be arranged on the arranged on left and right sides of temperature thermocouple and the refractory brick 3 of top, refractory brick
Build by laying bricks or stones in kiln within the walls, temperature thermocouple stretches out kiln wall 10-12cm, refractory brick stretches out kiln wall 5-10cm, apart from temperature thermocouple 8-
15cm.
From temperature thermocouple left and right, three protected in the face of it, prevent the roller that ceramic rod drops in sintering process
Rod pounds disconnected temperature thermocouple above temperature thermocouple or the roller rod that drops is poured over kiln wall from arranged on left and right sides by temperature thermocouple
Break, the mensure of impact kiln temperature, the guarantee production order, the repair and replacement frequency of minimizing temperature thermocouple, low cost of manufacture,
It is skillfully constructed.
