Description

Closed ladle baking device

Technical Field

The utility model relates to a ladle baking equipment field especially relates to a closed ladle baking equipment.

Background

The ladle is a steel container for containing molten steel, refractory bricks are built in the ladle, and the molten steel flows out from an outlet at the bottom and is cast; the ladle is mostly used in steel plants and foundries to receive molten steel and perform pouring operation before an open hearth furnace, an electric furnace or a converter. The steel ladle is generally required to be baked after the refractory brick is newly built and before molten steel is filled, so that explosion caused by moisture in the steel ladle is prevented; in addition, in the steel making process, in order to improve the utilization rate of molten steel and prolong the service life of a ladle, the ladle needs to be heated to provide red heat. The device for baking the ladle is a ladle roaster, also called a ladle roaster.

The ladle baking is one of important links in a steelmaking production process, at present, combustion products of a ladle baking device are all directly discharged in atmosphere, the thermal efficiency is low, the operation environment of a workshop is seriously polluted, and the pollution is caused to the atmosphere.

In view of the above, a closed ladle baking apparatus has been developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough among the prior art, provide a closed ladle baking equipment, stopped the emission of combustion products in the workshop the inside, reached and toast the workshop zero release, reduced nitrogen oxide and discharged, can reduce calorific loss, promote the ladle and toast speed, thermal efficiency is promoted, reduces fuel consumption.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a closed ladle baking device is composed of: the device comprises a shell, a heat-insulating layer, a flue gas recovery pipeline, a sealing mechanism, a cover plate and a combustor; the inner wall of casing sets up the heat preservation, and the sitting room constitutes the baking chamber with the heat preservation, and casing lower extreme one side sets up flue gas recovery pipeline, and casing upper surface middle part sets up the ladle import, sets up the apron in the ladle import, sets up sealing mechanism between the periphery of apron and the ladle import, and sealing mechanism's periphery sets up in the inner wall of ladle import, and the upper surface middle part of apron sets up the combustor, and the bocca of combustor communicates with each other with the casing is inside.

The cover plate is made of refractory fibers.

The insulating layer is made of refractory fiber.

The sealing mechanism adopts mechanical sealing.

The utility model has the advantages that: the cover plate is arranged below the suspension arm of the roaster, and when the roaster is used, the cover plate can be unfolded and fall down through the suspension arm of the roaster so as to facilitate the passing in and out of a steel ladle chamber, the steel ladle is placed in the roasting chamber, the cover plate is covered, roasting is started, smoke generated during roasting is conveyed to the dust removal device by the smoke recovery pipeline to be uniformly recovered, the emission of combustion products in a workshop is stopped, the zero emission of the roasting workshop is achieved, the emission of nitrogen oxides is reduced, the sealing mechanism can prevent the smoke from overflowing, the heat preservation layer can reduce heat loss, the roasting speed of the steel ladle is increased, the heat efficiency is increased, and the fuel; the utility model discloses simple structure, design benefit, safe in utilization, excellent in use effect is fit for generally popularizing and applying.
