Ash clearing system of suspension type hot-blast stove

Abstract

The invention discloses an ash clearing system of a suspension type hot-blast stove. The ash clearing system comprises a main shaft vertically arranged, wherein the upper end of the main shaft is equipped with a stirring unit; an ash discharge unit is arranged on a shaft body below the stirring unit; a fire grate which is fixed with a hearth is arranged between the stirring unit and the ash discharge unit; a central hole for allowing the main shaft to pass through is formed in the middle position of the fire grate; ash dropping holes are uniformly distributed in the plate surface of the fire grate; a stove bottom plate is further arranged below the ash discharge unit; an ash outlet is formed in the stove bottom plate; and the air outlet is connected with an ash storage bin through a pipeline. The bottom of the stove is equipped with the stirring unit and the ash discharge unit, and the stirring unit rotates to stir the ash after ash generated in a mode that fuels are combusted is stacked on the stove bottom, so that on one hand, fuels which are incompletely combusted are in contact with air, and continuously combust at a high temperature of the hearth, on the other hand, the ash isprevented from being blocked after being stacked together to cause ash outlet blockage.

Description

technical field [0001] The invention relates to the technical field of a suspension type hot blast stove, in particular to a dust cleaning system for a suspension type hot blast stove. Background technique [0002] The suspension type hot blast stove refers to the use of fuel to fully contact with the air during the falling process in the furnace, and complete combustion in a suspended state, so as to make the combustion more complete. [0003] With the continuous development of grain drying equipment, the suspension hot blast stove is widely used for its high combustion efficiency, energy saving and environmental protection. In the prior art, the ashes generated after the fuel is completely burned will be piled up at the bottom of the furnace, and intermittent processing and cleaning of the ashes are required during use, which increases the labor intensity of the workers. Furthermore, part of the fuel will accumulate at the bottom of the furnace without being completely bu...

Problems solved by technology

In the prior art, the ashes generated after the fuel is completely burned will be piled up at the bottom of the furnace, and intermittent processing and cleaning of the ash are required during use, which increases the labor intensity of the workers

Furthermore, part of the fuel will accumulate at the bottom of the furnace without being completely burned during the falling process, resulting in insufficient combustion of the fuel and a waste of resources.
