Gas roller way kiln

Abstract

The invention belongs to the technical field of sintering equipment, and relates to a gas roller way kiln. The gas roller way kiln is characterized in that first-sixth units of a kiln body are preheating sections; smoke discharging branch pipes are arranged on the top surfaces and side surfaces of the first unit, the third unit and fifth unit of the kiln body; the smoke discharging branch pipes gather at a smoke discharging main pipe; seventh-twelfth units are sintering sections; a group of burners is arranged at the lower part of the roller way inside the seventh unit and eighth unit; eight groups of burners are arranged the ninth-twelfth units; thirteenth-twenty-first units are cooling sections; the thirteenth unit is a transition unit; the fourteenth unit is a quenching unit; the fifteenth-twentieth units are temperature dropping units; natural ventilation pipes are interlacedly arranged on the left and right side walls of the fifteenth-seventieth units; hot air extraction branch pipes are arranged at the tops of the eighteenth-twentieth units; an axial flow fan is arranged on each of the two sides of the twenty-first unit; the burners are reasonably arranged and are controlled by a PLC. According to the gas roller way kiln, accuracy of temperature adjustment and control is high; natural gas is used as the fuel; the partial temperature difference inside the kiln is small; the sintering curve of a product is stable.

Description

technical field [0001] The invention belongs to the technical field of sintering equipment, and in particular relates to a gas-fired roller kiln for sintering foam ceramic filters. Background technique [0002] The firing of traditional ceramic foam filters mostly uses ordinary electric furnaces, which have relatively high power consumption, high labor intensity, environmental pollution, high reburning consumption, low thermal efficiency of kilns, and electric furnaces mainly rely on electric energy to achieve heating and burning. It is a secondary energy source, the energy consumption is too high, and the temperature control is not easy to operate, resulting in uneven internal and external temperatures of the product and low product qualification rate. [0003] The Chinese patent application with the application number 201420836612.X discloses a gas-electric hybrid roller kiln, which includes a low-temperature zone, a high-temperature zone and a cooling zone arranged in seq...
