Description
Technical field
The present invention relates to field of metallurgical equipment, relate to more specifically a kind of metallurgical slag continuous discharge system.
Background technology
Metallurgical industry is the pillar of the national economic development, and the development that promotes field of metallurgy is the basic task that promotes China's modernization construction.
In the pyrometallurgy field, smelting can produce a large amount of high-temperature fusion slags when obtaining metal, and contains a large amount of valuable metals in the slag.Take copper smelting by pyrometallurgy as example: obtain in the process of matte with the sulphide ore smelting, cupric all surpasses 0.6% in the slag, even reaches 2.5%, will cause the great wasting of resources if discard, and therefore must the slag that metallurgy produces be recycled.
Reclaim in the technique at existing slag, with after the slag slow cooling again flotation be effective method, this kind arts demand is temporarily stored in slag in the slow cooling cinder ladle.The volume of slow cooling cinder ladle is substantially at 11m at present
3About, general method can be as described below.
Slag is discharged through chute by the floss hole of smelting furnace and is flowed directly in the slow cooling cinder ladle, when the slag liquid level in the slow cooling cinder ladle meets the requirements of height, with the floss hole shutoff of smelting furnace.Because be subjected to splashing and the restriction of hyperthermia radiation of slag stream, transporting equipment can only only just can be carried out the more operation of changing-over cinder ladle after the shutoff at floss hole fully away from discharge region, discharge process must be interrupted operation.The cinder ladle that then will fill slag by transporting equipment shifts out and connects the slag position, empty cinder ladle is put into to connect on the slag position again, opens floss hole again and again discharges and finish a slag emission cycle.
Yet in the process of prior art slag emission, the time of replacing cinder ladle, keying floss hole is grown and causes the slag emission cycle longer.In order as early as possible the slag in the smelting furnace to be discharged, only take the method for simultaneously operation of a plurality of floss holes to satisfy Production requirement in the production.Yet, open floss hole and usually all adopt the method for burning oxygen, serious to the refractory brick damage at floss hole place, and then to causing adverse effect the service life of smelting furnace.Simultaneously, contain a certain amount of pernicious gas in the slag emission process, many mouthfuls intermittent discharge, the burden of increase pernicious gas treatment system, and the off-gas recovery rate is low, and heat energy can't be recycled.
Therefore, how to avoid opening and closing floss hole in order to change cinder ladle because of frequent, and long problem of the slag emission time that causes becomes those skilled in the art's important technological problems to be solved.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of metallurgical slag continuous discharge system, it need not frequently open and close the smelting furnace floss hole, has effectively shortened the slag emission time.
A kind of metallurgical slag continuous discharge system provided by the invention, comprise that an end butts up against the chute of smelting furnace floss hole, also comprise support body, by stud connection in the buffers packet of described support body and be connected in described support body and drive the drive unit that described buffers packet is rotated around described hinge, described buffers packet is arranged at described chute below and corresponding with the other end of described chute, and described buffers packet is provided with the opening take described hinge as rotating shaft, and described opening below is provided with circulation and connects the slag device.
