Description

Technical Field

[0001] The utility model relates to the field of industrial sludge incineration treatment, in particular to a feeding device for a sludge incinerator. Background Art

[0002] Sludge incinerator is a kind of equipment used to treat sludge, which converts sludge into ash and waste gas through high-temperature combustion. Sludge incinerator is usually used to treat sludge generated by sewage treatment plants, industrial wastewater treatment plants, etc., as well as other wastes containing organic matter and high humidity.

[0003] Existing feeding devices can be divided into conveyor belt feeding devices and screw conveyor feeding devices. The conveyor belt feeding device uses a conveyor belt to transport sludge from the storage area or other equipment to the feed port of the incinerator, which can realize continuous transportation of sludge without interruption, ensuring the continuous operation and production efficiency of the incinerator. When the sludge is fed into the incinerator, the sludge may agglomerate during transportation, resulting in blockage of the feed port or pipeline, affecting the smooth transportation of the sludge, and may even cause damage to the equipment, reducing the reliability and life of the equipment. In addition, when the sludge is transported, the sludge may stick to the conveyor belt. If there is no cleaning device on the equipment, the sludge on the conveyor belt may gradually accumulate to form a thick sludge layer, causing the conveyor belt to run poorly, increasing friction resistance, reducing transportation efficiency, and requiring regular manual cleaning, increasing maintenance costs and downtime.
