NOVELTY - Device for cooling and air drying biomass molded fuel block, comprises e.g. a chain link conveyor, a flow guiding cover and an air guiding pipe, where the air guiding pipe is covered on the chain link conveyor, and two ends of the flow guiding cover are provided with a feed port and a discharge port. The chain link conveyor is composed of a support, a driving chain wheel, a driving shaft, a driven chain wheel, a driven shaft, a support component, a variable frequency motor and a chain link conveyor belt composed of two parallel chains and multiple connecting rods connected between the chains.    USE - Useful as a device for cooling and air drying biomass molded fuel block.    ADVANTAGE - The device: solves quick cooling and air drying problems of the biomass molded fuel block; and produces the fuel block continuously, and thus it improves production efficiency and reduces cost.    DETAILED DESCRIPTION - Device for cooling and air drying biomass molded fuel block, comprises a chain link conveyor, a flow guiding cover and an air guiding pipe, where the air guiding pipe is covered on the chain link conveyor, two ends of the flow guiding cover are provided with a feed port and a discharge port, and top of the flow guiding cover is provided with the air guiding pipe. The chain link conveyor is composed of a support, a chain link conveyor belt, a driving chain wheel, a driving shaft, a driven chain wheel, a driven shaft, a support component and a variable frequency motor, where the driving chain wheel and the driven chain wheel are located on the driving shaft and the driven shaft, and the driving shaft and the driven shaft are located on two ends of the support. The variable frequency motor drives the driving shaft. The support component is located on the support. The chain link conveyor belt is hung on the driving chain wheel and the driven chain wheel. The variable frequency motor drives the chain link conveyor belt to circularly run. The chain link conveyor belt is composed of two parallel chains and multiple connecting rods connected between the chains, where distance between the connecting rods is smaller than minimal section size of the fuel block.
