Abstract
The utility model relates to a fuel gas heating mantle. The heating mantle comprises a furnace cover, a furnace lining, a furnace shell, a hot air pipeline, an air connecting pipe, a combustion device, a conduit, a fuel gas connecting pipe, a fuel gas pipeline, a seal ring, a support, a quick coupling, a connecting hose, a waste gas pipeline, a combustion-supporting fan, a valve connecting pipe and a preheater, wherein the valve connecting pipe is provided with a plurality of valves, and the fuel gas connecting pipe is provided with a switch. According to the heating mantle, the combustion ratio of fuel gas can be increased by blasting due to the combustion-supporting fan, so that the combustion ratio of the combustion device can be improved; in addition, the losing of the heat quantity in a hot air transmitting process can be reduced by the reasonable layout of the hot air pipeline; and the fuel gas supply can be cut off due to the fact that the switch is arranged on the fuel gas connecting pipe, so that the heating can be conveniently stopped. The fuel gas heating mantle provided by the utility model is simple in structure and convenient to use.
Description
Technical field
The utility model relates to bell furnace field, specifically gas heating cover.
Background technology
Bell furnace refers to that body of heater is a cover, or furnace bottom is motionless, and bonnet moves, or bonnet is motionless, the heat-treatment furnace that furnace bottom moves.Bell furnace is used for the annealing in process of steel wire, steel pipe, copper strips, copper cash and the silicon steel sheet etc. of metallurgy industry.Wherein copper strips is mainly applicable to the heat treatment of the materials such as brass band, bronze band, section copper strip, copper belt.
The case of bell furnace is welded by steel plate and shaped steel, and inside is furnace lining, and heater (heating or fuel burner nozzle) is arranged in burner hearth around on wall.Table is provided with two guide upright posts, is convenient to case and installs, and according to Technology for Heating Processing, requires difference to protect by different atmosphere.General gas heating cover, cooling dome, table, inner cover and corresponding cooling, evacuation system composition.For improving the quality of products and annealing cycle shortening, inner cover is identical with table quantity, and heating mantles is generally many 1 of the half of table quantity, and cooling dome is table quantity half left and right.Bell furnace batch is large, and temperature uniformity requires high, and forced convertion fan is set, and carries out furnace atmosphere circulation.
Heating mantles on market is mostly electrothermal, seldom be designed to combustion type, because electric formula heating energy consumption is higher, more and more by client, do not accepted, but replace owing to there is no the gas bell-type furnace that reliability is higher, so client still uses old-fashioned electric heating bell furnace mostly, at present, energy consumption low, maintenance cost few, efficiency high combustion type heating mantles high less than reliability also.
Utility model content
The utility model, just for above technical problem, provides the combustion type that reliability is high, energy consumption is low, maintenance cost is few, efficiency is high heating mantles.
For achieving the above object, the technical solution adopted in the utility model is:
Gas heating cover, comprise bell, furnace lining, furnace shell, hot air duct, air tube connector, burner, penetration pipe, gas connection pipe, gas pipeline, sealing ring, bearing, snap joint, connecting hose, exhaust piping, combustion fan, valve tube connector, preheater, it is characterized in that furnace shell is arranged on bearing, furnace shell top is provided with bell, furnace shell lower seat inner side is provided with sealing ring, furnace shell inside is provided with furnace lining, preheater is arranged on furnace shell one side, preheater one side arranges exhaust piping, preheater opposite side is connected with hot air duct by valve tube connector, hot air duct below is connected with burner by air tube connector, between hot air duct and burner, penetration pipe is set, burner below arranges gas pipeline, between burner and gas pipeline, by gas connection pipe, be connected, connecting hose is set on gas pipeline, snap joint is set in connecting hose, furnace shell below burner isometry position arranges combustion fan.Multiple valves are set on valve tube connector.Switch is set on gas connection pipe.
Because the utility model is provided with combustion fan, can increase fuel gas buring rate by air blast, thereby improve burner efficiency of combustion, in addition, by the rational deployment to hot air duct, reduced the heat loss in hot blast transport process.And on gas connection pipe, be provided with switch, and can cut off gas supply, conveniently stop heating.
The utility model is simple in structure, easy to use.
