Abstract
A cupola furnace comprises a chimney, a furnace body and a blowing-in part, wherein a spray device is connected on the upper portion of the chimney, a feed inlet is arranged on the lower portion of the chimney, a front furnace is arranged at the front end of the furnace body, and a supporting pillar is connected at the bottom of the furnace body. The blowing-in part comprises a blast blower and air supply ducts, wherein the air supply ducts are connected with the blast blower, the air supply ducts are divided into four groups, air inlets are arranged on the furnace body up and down by all group air supply ducts. Openings of upper air inlets on the air supply ducts face downwards, and an angle of 45 degrees is formed between the upper air inlet on the air supply ducts and the furnace body, and openings of lower air inlets on the air supply ducts face upwards, and an angle of 45 degrees is formed between the lower air inlets on the air supply ducts and the furnace body. The cupola furnace is provided with multiple air inlets with different angles, burning fully of fuels in the cupola furnace can be guaranteed, and burning efficiency is improved.
Description
Technical field
The utility model belongs to the metallurgical casting field, is specifically related to a kind of metallurgical device.
Background technology
Furnace cupola is the visual plant of melting iron in Foundry Production, casting pig is fused into to be poured into after molten iron unpacks after cooling in sand mold and obtain foundry goods.Furnace cupola is a kind of vertical cylindrical shape smelting furnace, is divided into forehearth and rear stove.Forehearth is divided into again tapping hole, cupola well and gap bridge before slag notch, bell.Rear stove is divided into again three parts, top stove, waist stove and cupola well.The waist stove separates with bustle pipe, repaiies stove and closes afterwards, seals with mud.Heat exchanger on the stove of top.Be mainly used in iron casting production, also in order to coordinate pneumatic steelmaking, because of the furnace roof opening upwards, therefore claim furnace cupola.In actual production, whether the furnace cupola air-supply fully directly affects temperature and the abundant degree of fuel combustion.
Summary of the invention
The purpose of this utility model is to provide a kind of furnace cupola of sufficient combustion.
The utility model furnace cupola dust-removing desulfurating apparatus comprises chimney, shaft and air-supply part, and described chimney top is connected with spray equipment, and the chimney bottom is provided with charging aperture, and the front end of shaft is provided with forehearth, and the bottom of shaft is connected with pillar; Described air supplying part is divided and is comprised air blast and be connected the air supply duct that air blast connects, and described air supply duct has four groups, and every group of air supply duct has an air inlet up and down at shaft.
As optimization, in the enterprising air port of described air supply duct, it is at 45 ° with the shaft angle that Open Side Down, lower air inlet, and opening upwards is at 45 ° with the shaft angle.
The utility model furnace cupola is provided with a plurality of air inlets of different angles, has guaranteed the sufficient combustion of stove fuel, has improved efficiency of combustion.
