Abstract

The utility model is composed of a furnace body, an upper feed port, a lower feed port, a water outlet, a slag tap, a hot-blast system with a blower fan connected in series, and an adjustable tuyere, and is also provided with a star-cone-shaped and a groove-shaped devices for feeding iron scurf into a furnace. The utility model is a cupola by which the powder-shaped iron scurf including iron ash, iron dust and steel swarf can be directly thrown in the furnace, melted and cast into a plurality of machinable gray iron castings with stable carbon content of 3-4%.

Description

Multi-purpose small internal heated cupola

The utility model relates to metal smelt smelting furnace field, refers in particular to a kind of cupola.

The change bits stove of present fusible iron filings, the shape grey iron bits that can will loose are cast the ironcasting of non-processing directly into the stove fusing, reach the sharp useless purpose that reclaims resource, but all have following shortcoming: iron filings utilize face narrow, the molten iron that is fused into does not increase charcoal substantially, can not go into stove for phosphorus content less than 3% malleable cast iron iron filings and steel cuttings and be fused into machinable grey iron water but " white iron ", iron filings can not all utilize.Melting rate is not high, will topple over shaft when going out molten iron, and can only " stove one usefulness ".In the existing stove, adapted blower fan face is narrow, can only be with roots blower or leaf formula blower fan, and energy consumption is big, and noise is big, and maintenance is inconvenient.

The purpose of this utility model is to propose a kind of small-sized internal heat type that can overcome above-mentioned shortcoming to use cupola more, can will loose shape iron filings (comprising iron ash, iron powder) and steel cuttings (short broken steel cuttings can be directly into stove, and long bits can be pressed into the fritter fed to boiler) but directly throw stove and melt and pour into the various grey cast-iron bodies that phosphorus content is stabilized in the worker of 3-4%.

The utility model also has following advantage: " multi-use ", promptly also can use as the blast-heating cupola of same specification, do not topple over shaft when going out molten iron, operation is with " cupola melting ".The adapted blower fan is wide, but equal adapted such as roots blower, leaf formula blower fan, centrifugal blower is especially used the special-purpose centrifugal blower of furnace cupola, energy consumption is low, noise is little, and is easy to maintenance.

The utility model is achieved in that by body of heater, chimney, charge door, delivery port, blower fan, the hot blast chamber, compositions such as air port, its feature is in being provided with two charge doors up and down, last charge door place burner hearth central authorities establish star taper iron filings and go into the stove device, be provided with flute profile iron filings between following charge door and the platform and go into the stove device, there is a step not to be higher than trough rim in the centre of groove one end, be provided with two or three mouths of a river and establish a slag notch in addition of tapping a blast furnace at the last height place, the mouth of a river of tapping a blast furnace in the bottom of body of heater, outside leading to the hot-air mouth of body of heater, be lined with cooling water tank, the hot-air mouth internal lining pipe that links to each other with warm-air pipe can change in the warm-air pipe through size, there is rotating shaft at the cooling water tank place of hot-air mouth, be connected with the chute on being located at body of heater, can change the angle of hot-air mouth and to change the length that hot-air mouth stretches into body of heater by rotating shaft moving in chute, the hot blast that leads to body of heater is that heating obtains through the hot cell by two typhoon machines polyphone.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is cutaway views of the utility model hot-air mouth;

Accompanying drawing 3 is that the utility model star taper iron filings are gone into stove device front view;

Accompanying drawing 4 is vertical views of accompanying drawing 3.

The 1-body of heater; The 2-blower fan; The 3-platform; 4-hot blast chamber; The 5-chimney;

The last charge door of 6-; 7-flute profile iron filings are gone into the stove device; 8-star taper iron filings are gone into the stove device;

The 9-mouth of a river of tapping a blast furnace; The 10-slag notch; The 11-warm-air pipe;

Charge door under the 12-cooling water tank 13-; The 14-rotating shaft;

The 15-cooling water; The 16-airduct.

Below in conjunction with drawings and Examples the utility model is further described:

Vertical body of heater 1, be provided with two charge doors, last charge door 6 and following charge door 13, last charge door 6 place burner hearth central authorities establish star taper iron filings and go into stove device 8, be provided with flute profile iron filings between following charge door 13 and the platform 3 and go into stove device 7, in the central authorities of groove one end one step is arranged, this step is not higher than trough rim, purpose is that bits material one is divided into three, makes and expects evenly to distribute into the bits of stove.When reinforced, because star awl iron filings are gone into the effect of stove device 8, the bits material is uniformly distributed in the burner hearth from last charge door 6, middle few bits can not increase too greatly to the resistance of furnace gas, can increase to feed intake.Be provided with two, three mouths of a river 9 of tapping a blast furnace in the bottom of body of heater 1, and establish a slag notch 10 in addition at upper water-out iron open height place, outside the warm-air pipe 11 that leads to body of heater 1, be lined with cooling water tank 12, the hot-air mouth internal lining pipe that links to each other with warm-air pipe 11 can change warm-air pipe through size, there is rotating shaft 14 at cooling water tank 12 places of hot-air mouth, be provided with chute at body of heater 1, stretch into the length of body of heater 1 by rotating shaft 14 moving in chute angle that can change hot-air mouth and angle that changes hot-air mouth and change hot-air mouth.The hot blast that leads to body of heater 1 is to deliver to warm-air pipe 11 by two typhoon machines, 2 polyphones through hot blast chamber 4 and by airduct 16.

Owing to be provided with a plurality of mouths of a river of tapping a blast furnace, can select different height to go out molten iron and need not topple over body of heater, and mouthful slag tap in addition, very convenient.

When the utility model is used as cupola and is used, close and close charge door, it is reinforced to open down charge door, as when being used as furnace cupola and using, closes down charge door, opens charge door and feeds in raw material, and can reach the purpose of multi-use like this.

The utility model is owing to adopted unique design, less demanding to iron filings, and has a function of cupola and furnace cupola, factory leads to machining, setting up such cupola furnace, can make full use of the waste material that the our factory produces, is a kind of small investment, cupola furnace easy to implement, that energy consumption is low, efficient is high.
