Problems solved by technology

[0002] At present, in the existing rock wool production enterprises, the cupola combustion-supporting tuyeres (i.e., the air distribution mechanism) are all multiple tuyeres, distributed around the furnace body, and the processing is complicated. At the same time, the wind direction in the furnace will be uneven, resulting in poor gas flow. Insufficient combustion in the furnace reduces the production efficiency; moreover, the preheated combustion-supporting air enters the furnace through multiple air ducts, which will cause excessive heat loss, which is not conducive to melting

Embodiment Construction

[0012] The present invention as Figure 1-2 As shown, it includes a furnace body 1 and a tuyere 2 provided on the furnace body, the tuyere 2 is provided with an air distribution body 3, the air distribution body 3 is columnar, and the air distribution body 3 is detachably connected to the In the tuyere 2, the air distribution body 3 is evenly arranged with a number of ventilation holes 4 in the axial direction, and the ventilation holes 4 are connected with the ventilation pipe 5; the ventilation holes can be installed obliquely in application, so that the air pipe can directly blow out the inclined air. Combustion wind.

[0013] The air duct 5 is provided with spouts 6, and the spouts 6 are located in the furnace body 1. The spouts on the air duct 5 are uniformly distributed in a circular shape in the axial direction of the air distribution body, and are directed towards the respective The outer side of the hood is inclined (that is, the inclination of the outer ring), which...

Abstract

The invention provides a cupola furnace which is simple in structure, convenient in machining and operation, and high in work efficiency. The cupola furnace includes a furnace body and a tuyere arranged on the furnace body, wherein a cylindrical air distribution body is arranged in the tuyere in a detachably connected manner; a plurality of vent holes are uniformly distributed in the air distribution body axially, and are communicated with air pipes; a nozzle is arranged on each air pipe and positioned in the furnace body; the nozzles on the air pipes are annularly and uniformly distributed on the air distribution body axially, and are inclined towards the respective outer sides. The cupola furnace provided by the invention has the advantages that the combustion-supporting tuyere is simple, so as to facilitate processing; the air distribution body is arranged in the combustion-supporting tuyere in a detachably connected manner, so as to be conveniently replaced to meet different processing requirements; the vent holes are formed in the air distribution body and communicated with the air pipes, so that combustion-supporting air can be uniformly distributed in the furnace, which achieves sufficient combustion in the furnace and improves the work efficiency.

Description

technical field [0001] The invention relates to an air distribution mechanism of a cupola. Background technique [0002] At present, in the existing rock wool production enterprises, the cupola combustion-supporting tuyeres (i.e., the air distribution mechanism) are all multiple tuyeres, distributed around the furnace body, and the processing is complicated. At the same time, the wind direction in the furnace will be uneven, resulting in poor gas flow. If the situation is not sufficient, the combustion in the furnace is insufficient, which reduces the production efficiency; moreover, the preheated combustion-supporting air enters the furnace through multiple air ducts, which will cause excessive heat loss, which is not conducive to melting. Contents of the invention [0003] Aiming at the above problems, the present invention provides a cupola with simple structure, convenient processing and operation, and improved work efficiency. [0004] The technical solution of the p...
