Abstract
The invention discloses a mullite thermal-insulation brick tunnel furnace, and relates to the field of tunnel furnace equipment. The mullite thermal-insulation brick tunnel furnace comprises a workbench, a furnace body is arranged at the top of the workbench, a control box is arranged at the bottom of the workbench, a supporting plate is connected to one end of the top of the workbench, a second conveying belt is arranged at the portion, located at one side of the furnace body, of the top of the workbench, and a first conveying belt is arranged inside the furnace body. According to the mullitethermal-insulation brick tunnel furnace, a first electric push rod, a furnace body inlet, a second electric push rod, a furnace body outlet and infrared sensors are arranged, a mullite brick is detected through the infrared sensors, the wavelength of the detected mullite brick is transformed into an electric signal, then the electric signal is transmitted to a PLC, the PLC controls the first electric push rod or the second electric push rod to move, so that the first electric push rod or the second electric push rod drives the furnace body inlet or the furnace body outlet to move upwards, then the furnace body inlet or the furnace body outlet is opened, and entry of the mullite brick is facilitated.
Description
technical field [0001] The invention relates to the field of tunnel furnace equipment, in particular to a mullite insulation brick tunnel furnace. Background technique [0002] Tunnel oven is a tunnel-type mechanical equipment that completes product baking through heat conduction, convection, and radiation. The oven body is generally very long, with a minimum of 6 meters and a length of 60 to 80 meters. The baking room is a long and narrow tunnel. The width is generally 80cm to 140cm, and there is a continuously running conveying system in the tunnel. Mullite brick refers to a high-alumina refractory material with mullite as the main crystal phase, and the general alumina content is between 65% and 75%. , Mainly used for hot blast furnace roof, blast furnace body and bottom, glass melting furnace regenerator, ceramic sintering kiln, dead corner furnace lining of petroleum cracking system, etc. [0003] The existing tunnel furnace for baking mullite insulation bricks does no...
