Problems solved by technology
The existing ceramic rollers are mostly single-layer tubular structures after molding and sintering, and the load capacity of the rollers is poor. Increasing the wall thickness is currently a commonly used method to improve the strength of the rollers. This method can increase the strength of the rollers to a certain extent. effect, but the increase in wall thickness leads to an increase in the weight of the roller. On the one hand, it will increase the production cost of the roller. The heat accumulated in the stick at high temperature will not be dissipated in time, resulting in internal stress, which will cause inconsistent shrinkage inside and outside the roll, which will easily lead to cracks and then burst of the roll. Broken and dropped, the roller rod explodes or breaks and falls, dumped on the kiln wall and easily breaks the temperature measuring thermocouple installed on the kiln wall, making it impossible to measure the temperature in the kiln, seriously affecting production

Embodiment Construction
[0013] Such as figure 1 As shown, the sintering kiln temperature measuring thermocouple protection device includes a sintering kiln 1. The left and right sides of the sintering kiln are kiln walls, and the front and rear sides are kiln doors. Couple 2, a protection device is set around the temperature measuring thermocouple 2, the protection device is refractory brick 3 arranged on the left, right and above the temperature measuring thermocouple, the refractory brick is built in the kiln wall, and the temperature measuring thermocouple The couple protrudes from the kiln wall by 10-12cm, the refractory bricks protrude from the kiln wall by 5-10cm, and the distance from the temperature measuring thermocouple is 8-15cm.
[0014] Protect it from the left, right and upper sides of the temperature measuring thermocouple to prevent the ceramic roller from breaking the temperature measuring thermocouple from above the temperature measuring thermocouple during the sintering process or ...

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 [0001] The invention belongs to the field of ceramic roller rod production, and in particular relates to a temperature-measuring thermocouple protection device for a sintering kiln. Background technique [0002] Ceramic rods refer to refractory products made of clay refractory raw materials and natural mineral raw materials through the process of selection, crushing, forming, and calcination. Ceramic rollers are used in roller kilns in the glass ceramic industry. As a kind of refractory kiln furniture, ceramic sticks play the role of supporting and conveying ceramic bodies and products in roller kilns and roller kilns. They are the core components of roller kilns. The firing cycle and automatic operation have made important contributions, and have been widely used in the fields of architectural sanitary ceramics, daily ceramics, electronic ceramics, magnetic materials, glass heat treatment, and wear-resistant devices. At present, the roller kiln is developi...
