A hot blast stove with automatic dust removal

Abstract

The invention relates to a hot air stove for automatic dust removal, which includes a shell, a combustion furnace and a heat exchanger connected with the combustion furnace. The combustion furnace is provided with a dust removal assembly that can rotate to shovel the inner wall of the combustion furnace. The combustion furnace A shovel knife for shoveling ash is accommodated in the furnace wall, and the hydraulic cylinder in the ash cleaning assembly pushes the shovel knife out of the furnace wall and is driven by the rotating ring in the upper combustion furnace to rotate along the furnace wall to achieve ash shoveling. The invention accommodates and protects the shovel by setting up a storage cavity and a sliding door on the inner wall of the combustion furnace, so as to prevent the shovel from interfering with the combustion of the fuel inside the combustion furnace or being damaged by the long-term heating of the combustion furnace. The motor drives the gear, and the gear passes through the The gear teeth on the outer wall of the rotating ring drive the rotating ring to rotate, and the rotating ring drives the shovel pushed out of the storage chamber by the hydraulic cylinder through the card slot, and performs a circular rotation on the inner wall of the furnace to realize the cleaning operation of the inner wall of the furnace, which is automatic The cleaning avoids manual troubles.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a hot blast stove with automatic dust removal. Background technique [0002] The heat exchange type hot blast stove mainly uses a high temperature resistant heat exchanger as the core component. This component cannot use a metal heat exchanger, but can only use a high temperature resistant ceramic heat exchanger. The gas is fully burned in the combustion chamber, and the heat after combustion The air, through the heat exchanger, exchanges heat to fresh cold air, which can make the temperature of fresh air reach more than 1000 degrees. [0003] After the furnace body of the existing hot blast stove is used for a long time, a thick layer of ash will accumulate on the furnace wall, and this ash will affect the heating effect of the whole hot blast stove. The cleaning of the inner wall is carried out manually, but manual cleaning is relatively cumbersome and troublesome, an...

[0003] After the furnace body of the existing hot blast stove is used for a long time, a thick layer of ash will accumulate on the furnace wall, and this ash will affect the heating effect of the whole hot blast stove. The inner wall is cleaned manually, but the manual cleaning is cumbersome and troublesome, which is very inconvenient
