Abstract
The utility model discloses a cupola furnace which comprises a furnace body arranged on a base. The furnace body is of a barrel body with the middle portion concaved inwards to form an arc shape, an air inlet and an air outlet are formed in the lower section and the top portion of an outer wall respectively, a feeding port is formed in the upper section of the outer wall of the furnace body, a tap hole and a slag hole are respectively formed in the outer wall below the air inlet, and a tapered pipe joint is arranged on the air outlet. The cupola furnace is novel in structural design, the middle portion of the furnace body is concaved downwards to form the arc shape, the air pressure in the furnace body can be increased through the cooperation of the air inlet, the air outlet and the tapered pipe joint, the heat utilization efficiency in the furnace body can be improved, meanwhile, a ceramic high temperature resisting coating is arranged on the inner wall of the furnace body, the high temperature resisting performance of the furnace body is improved, and materials are not prone to conglutination.
Description
technical field:
The utility model relates to the casting process equipment, relates in particular to a kind of furnace cupola.
background technology:
Furnace cupola, because of the furnace roof opening upwards, therefore claim furnace cupola, be the visual plant of melting iron in Foundry Production, casting pig is fused into after molten iron to be poured into and unpacks after cooling in sand mold and obtain foundry goods.
Existing furnace cupola is a kind of vertical straight tube shape smelting furnace, be mainly used in iron casting production, also in order to coordinate pneumatic steelmaking, there is certain defect in vertical straight tube shape smelting furnace, the easy adhesion material of inboard wall of furnace body, the body of heater capacity is little, and it is abundant that the air channel from air inlet, body of heater to air outlet can not increase the body of heater internal combustion, thereby cause production efficiency lower.
the utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of furnace cupola, reasonable in design, and the capacity of body of heater inside increases, and air channel has increased blast can, so that the body of heater internal-combustion is abundant, improve production efficiency.
The technical solution of the utility model is as follows:
Furnace cupola, comprise the body of heater be installed on base, it is characterized in that: described body of heater is the middle part curved cylindrical shell that caves inward, outer wall hypomere and the top of body of heater are respectively equipped with air inlet and air outlet, the furnace body outer wall epimere is provided with charging aperture, have tapping hole and slag notch on the furnace body outer wall of described air inlet below, the pipe joint of taper is installed on described air outlet.
Described furnace cupola is characterized in that: described inboard wall of furnace body is provided with the ceramic high-temperaure coating.
The utility model has the advantages that:
The utility model structural design novelty, camber caves inward in the middle part of body of heater, coordinate air inlet and air outlet and conic pipe joint can increase the blast in body of heater, improve the heat utilization efficiency of body of heater inside, inboard wall of furnace body is provided with the ceramic high-temperaure coating simultaneously, improved the body of heater resistance to elevated temperatures, material is not prone to adhesion yet.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to Fig. 1:
Furnace cupola, comprise the body of heater 2 be installed on base 1, the cylindrical shell that body of heater 2 is curved for middle part caves inward, the outer wall hypomere of body of heater 2 and top are respectively equipped with air inlet 3 and air outlet 4, body of heater 2 outer wall epimeres are provided with charging aperture 5, have tapping hole 6 and slag notch 7 on the furnace body outer wall of air inlet 3 belows, and the pipe joint 8 of taper is installed on air outlet, pipe joint 8 interface end inwalls are provided with internal thread, are convenient to be taken over.
Body of heater 2 inwalls are provided with ceramic high-temperaure coating 9, improve the resistance to elevated temperatures of body of heater, and inboard wall of furnace body can the adhesion material yet simultaneously.
