[0002] The chain-belt sintering furnace is mainly used for the sintering and welding, wax removal, drying and other processes of semiconductor devices, metal ceramics, thyristor devices, glass packaging devices and various thick film circuits. It is a continuously working tunnel-type structure sintering furnace. When in use, the furnace body is heated to a certain temperature through the heating components, and the product to be heated is placed on the conveyor belt. When the product passes through the furnace body through the conveyor belt, the high temperature environment in the furnace makes the product heated or dried. The existing tunnel furnace heating usually adopts resistance wire or fuel oil; the tunnel furnace using resistance wire not only heats up slowly and consumes high energy, but also has unstable firepower, resulting in low food production, uneven heating and poor taste; the tunnel furnace using fuel oil has a large amount of exhaust gas, which can easily cause the product to produce odor, and has a low safety factor and high energy consumption.

[0003] Publication number: CN212994036U, the utility model discloses a mesh belt type conveying tunnel furnace, including a tunnel furnace body, the tunnel furnace body is composed of a furnace entry platform, a baking furnace body and a furnace exit platform, the furnace entry platform is located at one end of the baking furnace body, the furnace exit platform is located at the other end of the baking furnace body, a mesh belt inserted into the baking furnace body is arranged between the furnace entry platform and the furnace exit platform, the furnace entry platform is composed of a furnace entry frame assembly, a passive roller, a lower pressure roller, a deviation correction roller, a rocker assembly, a first bracket, a second bracket and an electric push rod, and the furnace exit platform is composed of a furnace exit frame assembly, a furnace exit roller, an active roller, a reduction motor, a speed reducer and a tensioning roller.

[0004] The above-mentioned problems: Although the above-mentioned patent can effectively prevent damage to the steel belt when abnormal correction occurs, the chain belt passes through the feed and discharge ports of the furnace body, which causes the heat of the furnace body to be easily lost during the heating and drying process, easily causing waste of heat energy and affecting the thermal efficiency of drying.
