Embodiment 1

[0049] When the molten iron in the smelting blast furnace is poured into the crucible, a large amount of yellow smoke and dust overflows. In order to overcome the shortcomings of the existing ash unloading and dust collection devices that cannot work normally, the high-temperature dust collection baffle retractable device of the present invention is implemented.

[0050] A high-temperature dust collection hood device is installed at the position where the molten iron in the smelting blast furnace is poured into the crucible. The high-temperature dust collection device includes a high-temperature dust collection baffle device, a high-temperature dust collection baffle retractable device, etc.

[0051] The high-temperature dust collection baffle retractable device is installed at the position where the molten iron in the smelting blast furnace is poured into the crucible.

[0052]The dust device includes a high-temperature dust collection baffle device, a high-temperature dust co...

Abstract

A high-temperature dust-collection baffle folding and unfolding apparatus consists of an electromotor, a reducer, an internal contracting brake device, a forbidding-allowing apparatus, a reeling disc apparatus, a pulley, a steel rope, a high-temperature chain, a high-temperature dust-collection baffle, a dust-collection cover, a dust-collection draught fan and the like; the dust-collection cover main body is installed at the exactly upper end of a tap hole of a blast furnace body; and the high-temperature dust-collection baffle device is installed at the lower part of the dust-collection cover. The apparatus improves the dust collection efficiency of the dust-collection cover, reduces absorption on cold air or clean air, and reduces invalid energy consumption. Also the apparatus increases the effective capturing quantity of dust-laden gas, reduces pollution to operating post and surroundings. The apparatus is widely applicable to environment-protection technology field.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a device for receiving and placing a dust collecting baffle at the outlet of high-temperature molten iron of a smelting blast furnace. Background technique [0002] Due to the working environment temperature of 800°C-1200°C in the existing high-temperature dust collection device for molten steel in smelting blast furnaces, ordinary dust collection cover materials can hardly work normally, especially the published patent: "Dust Collection Device for Unloading Dust", application number: 200520099342 .X. [0003] Existing smelting blast furnace molten iron taphole, the train carries the crucible and drives into the bottom of the taphole molten iron tank. When the molten iron is poured into the crucible, there will be a large amount of yellow smoke and dust overflowing. It is necessary to install a dust collection hood device to collect the smoke and dust to achieve ...
