Abstract
A submerged tube type electrical heating holding furnace comprises a furnace body, a furnace cover and an electrical heating device, which is characterized in that the electrical heating device is a submerged tube type heater submerged in liquids. The submerged tube type electrical heating holding furnace has the advantages that the working efficiency of the electrical heating holding furnace is improved, the aluminium liquid products with high quality is obtained, the energy consumption of the equipment is lowered, the service life is prolonged and the work environment around the equipment is improved.
Description
Technical field
The utility model relates to a kind of industrial furnace, particularly a kind of tubular type electrical heat tracing stove that soaks.
Background technology
The transfer mode of heat has three kinds of convection current, radiation and conduction, with conduction pattern the most effectively.And existing aluminium alloy electric heat tracing stove mainly is to adopt heating wire aluminium liquid to be carried out the mode of radiation heating, the efficient that the mode of radiation heating heats is lower, the temperature height of electrical heating wire, and service life is short, poor reliability, and when work, owing to be to belong to the indirect mode, the air themperature on aluminium liquid top raises, aluminium liquid is easy to generate oxide in the stove, greatly reduce the quality of work efficiency and aluminium liquid, simultaneously the temperature of surrounding environment is higher, can give that operating personnel are healthy to have brought threat.So, how to improve and improve the important topic that the electrical heat tracing stove becomes those skilled in the art's research.
Summary of the invention
What the purpose of this utility model had provided a kind of simple in structure, easy to use, good sealing effect, raising energy utilization efficiency is used for low-temperature air conditioner double thermal insulation access door structure, has solved the deficiencies in the prior art part.
The purpose of this utility model is achieved in that a kind of tubular type electrical heat tracing stove that soaks, and comprising: body of heater, bell and electric heater unit is characterized in that: described electric heater unit soaks tube heater and is immersed in the liquid for soaking tube heater.
The described tube heater that soaks is made up of heating wire and the dip tube that is enclosed within the heating wire outside.
The material of described dip tube is SiC or SiN.
The mounting means of described dip tube is horizontal installation, is fixed by the mount pad that is located at body of heater inside.
Described heating wire is fixed by the insulation fixed block of dip tube inside.
Described soaking has junction pole in the tube heater.
Described body of heater is provided with insulation cover.
The utility model has the advantages that: improve the operating efficiency of electrical heat tracing stove, can obtain high-quality aluminium liquid product, reduced the use energy consumption, improve the service life of equipment, the working environment around the improvement equipment.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is the structural representation of heater in the utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
The specific embodiment
Among Fig. 1, a kind of tubular type electrical heat tracing stove that soaks, comprising: body of heater 13, bell 12 and electric heater unit 11 is characterized in that: described electric heater unit is 11 to soak tube heater, soaks tube heater and directly is immersed in the liquid.
Among Fig. 2, the described tube heater that soaks is made up of heating wire 1 and the dip tube 2 that is enclosed within heating wire 1 outside.
The material of described dip tube 2 is SiC or SiN.
The mounting means of described dip tube 2 is horizontal installation, and is fixing by the mount pad 4 that is located at body of heater 13 inside.
Described heating wire is fixing by the insulation fixed block 3 of dip tube 2 inside.
Described soaking has junction pole 5 in the tube heater.
Described body of heater is provided with insulation cover.
The utility model has changed with the mode of with heating wire aluminium liquid being carried out radiation heating at present, but adopt the mode of conducting, the mode that electric heater is directly immersed aluminium liquid heats, the efficiency of heating surface is greatly improved, the heating rate of aluminium liquid can reach 25 ℃/hour, has improved 60% than existing equipment.Simultaneously, owing to adopt and to soak the mode that tube electric heater directly immerses aluminium liquid and heat, make furnace atmosphere temperature and oxygen content greatly reduce, substantially stopped the generation of stove inner oxide, work efficiency and aluminium liquid quality have been improved, can reduce more than 30% by the existing equipment of loss-rate, aluminium liquid scaling loss reduces more than 50%.Novel electric heater adopts horizontal mounting means, so the structure of burner hearth is adjusted, adopt at burner hearth and to water when material feeding carries out one-piece casting, the special process reservation process is carried out in the position that electric heater is installed, heater is installed the particular form that adopts based on flat seal, the equipment whole reliability of making is guaranteed that the equipment whole service life greatly improves, and can exempt overhaul in 5 years.The utility model need not by the electrical heating wire in the heating lid of existing equipment aluminium liquid to be carried out the radial pattern heating again, so heating lid in body of heater top is become insulation cover, simultaneously since furnace atmosphere temperature and oxygen content greatly reduce, make that insulation cover thickness is reduced, heat-insulating property greatly improves, more effectively reduce heat dissipation capacity, reduced ambient temperature, improved the thermal efficiency.
When the heat tracing furnaceman did, aluminium liquid entered from advancing the aluminium mouth, through advancing the aluminium groove, flow in the burner hearth, soaked the electrothermal wire heating in the tube heater, directly aluminium liquid was heated, and reached the effect that aluminium liquid is incubated.
The utility model has the advantages that: improve the operating efficiency of electrical heating holding furnace, can obtain high-quality aluminium liquid product, reduced Energy in use, improve the service life of equipment, the working environment around the improvement equipment.
