Description
Technical field
The utility model relates to a kind of introducing device, is specifically related to a kind of hot molten slag introducing device be applied between skull melting furnace in mineral wool production technique and whizzer.
Background technology
Blast furnace hot molten slag is a kind of byproduct that ironmaking produces.Blast furnace hot molten slag not only has very high temperature (1400 ~ 1600 DEG C), and its average heat content is about 1670MJ/t, belongs to the residual heat resources of high-quality; And also containing a large amount of mineral substance in slag.In order to make full use of the mineral in the residual heat resources of blast furnace hot molten slag and slag, be introduced directly into being in the hot blast furnace hot molten slag of industry in skull melting furnace by blast furnace residue channel, and add the physicochemical property that a small amount of modified material (Powdered) improves slag wherein; Then by skull melting furnace through clarification, homogenizing, reach the qualified melt that fibroblast requires and introduce whizzer by feed chute, melt gets rid of and makes fiber by the centrifugal force that whizzer is produced by the pivotal Centrifugal rolling of high speed and high velocity air compound action; Like this while making full use of waste residue sensible heat, also can produce mineral wool, cinder microcrystalline glass etc. and there is building material product compared with high added value.
As shown in Figure 4, current a kind of hot molten slag introducing device, this introducing device is between the discharge port and whizzer of skull melting furnace.Owing to considering the restriction of the discharge hole structure of hot molten slag temperature in skull melting furnace and skull melting furnace, the discharge outlet of skull melting furnace is difficult to arrange valve to control the switch of discharge port; But whizzer may produce fault in the course of the work, whizzer is once break down, then need to cut off the hot molten slag introducing whizzer, hot molten slag is avoided to destroy whizzer, thus the accident groove 15 that current introducing device generally includes feed chute 12 and is connected with feed chute, and the friendship interface of feed chute and accident groove is provided with the first flashboard 14, the friendship interface of interior, the close feed chute of feed chute and accident groove is provided with the second flashboard 13.When whizzer normally works, the first flashboard closedown accident groove, the second flashboard is mentioned, thus the hot molten slag in feed chute is introduced in whizzer, to be got rid of by melt make fiber by whizzer.When whizzer breaks down, the second flashboard is put down, and the first flashboard is mentioned, thus the hot molten slag in feed chute is derived by accident groove, avoid hot molten slag to destroy whizzer; But because hot molten slag has very high temperature (about 1300 DEG C), thus usually need in first, second flashboard to arrange cooling-water duct, utilize water coolant to cool, avoid flashboard to soften, be out of shape; But so flashboard will be in cold conditions (relative to hot molten slag), and be in cold conditions due to flashboard, infiltrate that hot molten slag between flashboard and slag chute surface is easily cooled solidifies, make flashboard together with slag chute surfaces stick; This often easily causes flashboard to be difficult to be raised, and then causes the hot molten slag in feed chute to overflow feed chute, destroys peripheral equipment.
