Fuel leveling device for downdraft gasifying furnace

Abstract

A fuel leveling device for a downdraft gasifying furnace that can effectively turn over and flat fuel constantly in the gasifying furnace comprises a gasifying furnace simple barrel, wherein a gasifying furnace top plate is connected with the gasifying furnace simple barrel, a mechanic shaft is relatively and rotationally installed on the gasifying furnace top plate, an electric motor is connected with the upper end of the mechanic shaft in a transmission manner, the lower end of the mechanic shaft is inserted in the gasifying furnace simple barrel, and the middle part of the mechanic shaft is installed below the gasifying furnace top plate. The fuel leveling device is characterized in that a material pulling plate shaft and a material flatting plate are fixedly connected at the lower part of the mechanic shaft, material pulling plates are fixedly connected with the material pulling plate shaft, and the material flatting plate is installed on the material pulling plate shaft. The material pulling plate shaft is mutually vertical to the mechanic shaft, both ends of the material pulling plate shaft are separately installed at the two sides of the mechanic shaft, and material pulling plates are connected with the material pulling plate shaft at both sides of the mechanic shaft. The invention is applied to the downdraft gasifying furnace of the fixed bed to level the fuel in the gasifying furnace, thereby satisfying the constant operation requirement of the gasify serial device; and the fuel leveling device is a fuel adjusting leveling device for the downdraft gasifying furnace.

Description

technical field [0001] The invention relates to a device for rotating, adjusting and leveling particulate matter, in particular to a fuel leveler for a downdraft gasifier. Background technique [0002] With the continuous development of biomass gasification technology, it is found that the flatness of the fuel surface in the gasifier and the density of the fuel in each fuel layer have a decisive impact on the degree of fuel combustion and gasification efficiency. The smoothness and compactness of the fuel meet the operating requirements of the unit. At present, the fuel in the intermittent fixed bed downdraft gasifier is not equipped with a leveling material device, and the fuel leveling is manually operated, which is labor-intensive and cannot be operated continuously around the clock. Continuously running fixed bed downdraft gasifiers generally use a central rotating grate to spread the material. The fuel enters from the fixed feeding port of the gasifier. The central rot...

Problems solved by technology

At present, there is no fuel leveling device in the intermittent fixed bed downdraft gasifier, and the fuel leveling is manually operated, which is labor-intensive and cannot run continuously around the clock

Continuously operating fixed-bed downdraft gasifiers generally use a central rotating grate to spread the material. The fuel enters from the fixed feeding port of the gasifier, and the central rotating grate carries all the fuel in the furnace. It is difficult to spread the fuel in the furnace well.

Some people in China have used leveling devices in related technical fields, and leveling devices with only flatting functions cannot adapt to the ever-changing thermal conditions of fuel in the gasifier
