Gas generator for heating asphalt aggregate

Abstract

A gas generator for heating asphalt aggregate adopts the following method: a winding engine pulls a hopper to ascend along a steel channel through wire cables to reach the upper part of a hoisting frame when a shift fork opens water-sealing ring cover board; a discharge chute pours coal into the cylinder of a water-sealing clock cover mechanism; the coal goes into the hearth of a furnace body through the movable clock cover of the water-sealing clock cover mechanism and a coal divider to be uniformly dispersed on fire grates; the coal oxidoreduces with the mixture of steam and air input by a fan, namely gasification agent to generate gas, which is dedusted by a dust remover to burn in a mixing chamber of an asphalt mixing device; the steam is from a water chamber heated by the hearth; theupper part of an ash pan is driven by the cylinder to roll a push rod to push a ratchet to rotate so as to discharge the coal residue in the hearth. The gas generator for heating asphalt aggregate overcomes the defects of insufficient burning, high cost of diesel, harsh operation environment because of direct use of coal, acidating the asphalt, and slagging of burner, and is suitable for heating asphalt aggregate at asphalt mixing stations and asphalt mixing vehicles.

Description

technical field [0001] The invention relates to a gas generator for heating asphalt aggregates. Background technique [0002] At present, asphalt mixing equipment in the road construction and maintenance industry uses heavy residue oil, diesel oil or coal directly as fuel to heat asphalt aggregate. The quality of the concrete is adversely affected. When using it, a preheating device must be added to the burner to increase the fluidity. However, the preheating energy still needs to be obtained with diesel or gas, and the cost reduction is limited; the use of diesel is expensive and unsafe for storage and transportation. , Sometimes it is difficult to buy diesel oil; the use of pulverized coal as a direct fuel has the disadvantages of heavy pollution, harsh operating environment, acidified asphalt, slagging of the burner, and high power consumption of the pulverized coal pulverizer. Contents of the invention [0003] In view of the above situation, the present invention pro...
