Description
Technical field
This utility model is related to mineral hot furnace accessory, is a kind of cooling structure for mineral hot furnace blanking mouth.
Background technology
Blanking mouth is one of mineral hot furnace blanking system vitals, and raw material reaches what smelting process required by expects pipe
Cloth discharge position, by adjusting the depth in blanking mouth insertion bell, controls the angle of windrow.The circular degree of blanking mouth bottom and
Levelness has a significant impact to the uniformity of cloth.In burner hearth during smelting, flue-gas temperature is up to more than 700 degree, and charge level was with smelting
Journey is subsided, overturns, is burst, and sprays with flame, and blanking mouth needs to cool down in time, and otherwise high temperature is special to the erosion of blanking mouth
Seriously, along with raw material passes through friction, the collision to its inwall during blanking mouth, even more exacerbate the loss of blanking mouth.Blanking mouth
Length after serious ablation and shape can not meet smelting process and require, and will certainly affect the yield of mineral hot furnace and the matter of product
Amount.
The blanking mouth of mineral hot furnace blanking system generally adopts the water-cooling structure that cooling circulating water is heat transferring medium at present, its bag
Include welded by plate as Figure 1-Figure 2 and helix tube type as shown in Figure 3.The cooling structure of above two blanking mouth makes
With during expose some shortcoming and defect：
One just creates the inevitable ring of multiple tracks for welded by plate water-cooled material mouth, this structure from design level
Shape weld seam, welding capacity is big, and weld stress is big, and under bad working environments, high temperature, temperature shock, material block impact make weld stress discharge,
Weld seam easily ftractures leak；And the multiple 180 degree in water route change direction, to cooling circulating water circulation resistance very big, therefore this
Plant structure to be rarely employed；
Two for helix tube type water-cooled material mouth, and, compared with welded by plate water-cooled material mouth, welding capacity is significantly for this structure
Reduce, cooling circulating water circulates along spirality path, circulation resistance reduces compared with the former, but due to adopting single-screw, circulate road
Footpath longer universal more than 20 meters, therefore circulation resistance is still very big.For severe working condition, cooling effect still shows not
Foot, is such as in the blanking mouth of the alternate of metal-silicon furnace and center, just exposes during using single-screw pipe-type water-cooling material mouth
The not enough shortcoming of cooling capacity, the metal-silicon furnace carbon monoxide that charge level produces in smelting process is acute around the water-cooled material mouth
Strong burning, up to more than 700 degree, its cooling circulating water of cooling structure using single-screw tubular type only has one to the flue-gas temperature of generation
Bar cooling circuit, when cooling circulating water is recycled to outlet by water inlet, water temperature has reached 70-80 DEG C, in water-cooled material mouth
Portion has gradually produced gasification phenomenon near the position cooling circulating water of trocar sheath, and the gradually generation of vapor and accumulation hinder
Cooling circulating water circulates, and so that water-cooled blanking mouth internal pressure is increased, and ultimately results in the explosion of water-cooled material mouth it has to load down stops expecting
Maintenance, affects mineral hot furnace yield.
