Background
When the belt type cracking furnace is used for treating rubber, plastics, oil-containing ball-milling materials, oil sludge and other materials which can be cracked and have volatile materials, the bottom of the conveying steel belt can gradually form some solid materials such as ash, slag, coke blocks and the like. These materials move with the movement of the conveyor belt, but the movement is slow, and deposits are easily formed at the tail end of the furnace body. In the work of the belt type cracking furnace, a cleaning device is generally arranged to clean materials on a conveying belt into a material collecting box, but the existing cleaning device and the material collecting box are used for collecting the materials on the conveying belt, so that siltation cannot be removed, and once the siltation occurs, the conveying belt can be continuously lifted, so that the movement of the conveying belt is influenced, and the continuous operation of equipment is influenced. At the same time, after the occurrence of fouling, the self-cleaning function of the bottom solid material is lost. A deposition layer is formed at the bottom of the conveyor belt, and the heat transfer of the furnace body is affected.
