Abstract

The utility model provides a cupola, which has the keys that an air intake heating zone and a heating reduction zone of a furnace chamber of a furnace body are a blend radius station shape, a preheat zone and a melting zone are an equal diameter direct barrel type, and the diameter of the melting zone is greatly bigger than the diameter of the upper open of the air intake heating zone. A cold air heater is seated on the upper of the furnace body, a flue gas dust collector is arranged on the upper of the cold air heater, a chimney is arranged on the upper of the flue gas dust collector, and the flue gas dust collector is a water fog dust collector. The utility model has the advantages that the design is compact and reasonable, firstly, the furnace is convenient to be sleeved and no bridging, the wind resistance is small, the requirements of air distribution is low, the heat air is capable of being directly sent to the center of the furnace chamber, and the effects of central air supply is nearly achieved, secondly, the discharge capacity is less, the pollution for the environment is beneficial to be reduced, and an induced draft fan is not needed, thirdly, the floor area is small.

Description

A kind of cupola furnace

Technical field:

The utility model relates to a kind of cupola furnace.

Background technology:

Cupola furnace of the prior art mostly is the hood-shaped formula of barn lantern.The cupola furnace of the hood-shaped formula of this barn lantern, its structure and supporting all reasonable inadequately, the one, blind roaster is convenient inadequately, easily scaffold, windage is big, and air distribution requires high, and hot blast is difficult to be sent to the furnace chamber center, how along blowing on the furnace chamber border, combustion-supporting effect is poor, is unfavorable for reducing coke ratio and energy savings; The 2nd, blowdown flow rate is big, exhaust outlet temperature height, and dust removing effects is poor, and environmental pollution is serious, and needs air-introduced machine, the waste electric energy; The 3rd, floor space is big.

Summary of the invention:

The purpose of this utility model provides a kind of novel cupola furnace, in order to overcome the above-mentioned drawback of existing in prior technology effectively.The purpose of this utility model is to improve to realize on the basis in prior art cupola furnace, it comprises body of heater, cold wind heater, smoke duster and chimney, its main points are its body of heater, the air intake thermal treatment zone of its furnace chamber and the reducing zone of heating are reverse frustoconic, preheating zone and fusion zone are isometrical straight barrel type, and the diameter of melt zone is obviously greater than the back cut diameter of the air intake thermal treatment zone; The fire door place is provided with reversible charging bell; Its cold wind heater holder is connected to above the body of heater, smoke duster be positioned at the cold wind heater above, the two shell is integral or is connected, chimney occupy smoke duster above, link to each other with deduster; Said smoke duster is a mist dust remover, its lower housing portion toroidal shell body inboard is laid with annular conduit, is evenly equipped with at least four peripheral vertical tubes on the annular conduit, and the inboard of vertical tube is provided with some spray holes, the center of housing is connected with a center vertical tube, is provided with spray holes around this vertical tube.

The utility model design is compact rationally, and the one, blind roaster is more convenient, not scaffold; Windage is little, and air distribution requires low, and hot blast can directly be sent to the furnace chamber center, helps reducing the coke ratio energy savings, is close to the effect that reaches central air supply; The 2nd, blowdown flow rate is little, and the exhaust outlet temperature is low, is convenient to dedusting, helps alleviating the pollution to environment, also need not air-introduced machine, saves energy; The 3rd, floor space is little.

Description of drawings:

Fig. 1 is main TV structure figure of the present utility model

Fig. 2 is that the utility model main part master looks cutaway view

Fig. 3 is the A-A cutaway view among Fig. 2

The specific embodiment:

Accompanying drawing has provided a most preferred embodiment of the present utility model, with reference to the accompanying drawings, 1 is body of heater among the figure, the air intake thermal treatment zone 8-2 in its furnace chamber 8 and the reducing zone 8-1 that heats are reverse frustoconic, preheating zone 8-4 and fusion zone 8-3 are isometrical straight barrel type, and the diameter of melt zone 8-3 is obviously greater than the back cut diameter of air intake thermal treatment zone 8-2.This design, scaffold not, windage is little, helps reducing blast and is equipped with, and after hot blast is sent into from air intake thermal treatment zone 8-2, can directly enter the center of melt zone 8-3, realizes being close to central air supply; The fire door place is provided with reversible charging bell 9, to reduce blowdown flow rate, improves the UTILIZATION OF VESIDUAL HEAT IN effect; Its cold wind heater 5 seated connections are above body of heater 1, smoke duster 6 be positioned at cold wind heater 5 above, the two shell is integral or is connected, chimney 7 occupy smoke duster 6 above, link to each other with deduster 6, compact conformation is reasonable, be convenient to UTILIZATION OF VESIDUAL HEAT IN heating cold wind and flue gas ash removal, flue gas directly makes progress, and need not air inducing; Said smoke duster 6 is a mist dust remover, its lower housing portion toroidal shell body inboard is laid with annular conduit 10, be evenly equipped with eight peripheral vertical tubes 11 on the annular conduit 10, the inboard of vertical tube 11 is provided with some spray holes, the center of housing is connected with a center vertical tube 12, be provided with spray holes around this vertical tube 12, water enters annular conduit 10 and each

vertical tube

11,12 through water inlet pipe 3, spray from spray holes, dedusting is drenched down, flow out from deduster bottom swash plate then, be back to cyclic water tank 2 precipitations through outlet pipe and purify, recirculation is used.
