Description

Technical field

[0001] The invention relates to a temperature self-regulating device in a tunnel kiln. Background technique

[0002] The burners of the original tunnel kiln are directly installed on both sides of the tunnel kiln or on the top of the kiln. The position of the burners is fixed, that is, the angle of the burners cannot be adjusted. Both sides of the kiln walls and kiln roof are piled with refractory materials. The temperature of the original tunnel kiln can only be changed by changing the injection speed of air and gas and extensively adjusting the blast speed in the kiln. Its fatal shortcomings are:

[0003] 1. The original tunnel kiln changes the temperature in the kiln by changing the air and gas speed. The sintering temperature has a large variation range, and the gas flow rate variation range cannot be accurately controlled, which affects the sintering quality of refractory materials.

[0004] 2. During the combustion process of the original tunnel kiln, the gas ...

Examples

Embodiment 1

[0028] Such as Figure 1~Figure 2 As shown, a self-regulating device for temperature in the kiln includes: a kiln body, a temperature adjustment burner 3 arranged on the side wall of the kiln body, a blower 18 arranged at the end of the kiln body, a temperature sensor arranged in the kiln body, and PID control It also includes a first motor 9, a second motor 19, a first connecting shaft 10, a second connecting shaft 20, a first connecting block 11, a spherical surface pair 12, and a second connecting block arranged outside the kiln body 13 and the rotating hinge base 15, wherein the first connecting shaft 10 and the second connecting shaft 20 are perpendicular to each other, the first motor 9 is drivingly connected to one end of the first connecting shaft 10 through a gear transmission pair, and the second motor 19 is driven by a gear The pair is in transmission connection with one end of the second connecting shaft 20, and the other end of the first connecting shaft 10 and the...
