Abstract
The utility model discloses a radiant type glass isothermal heating furnace which is composed of heat-preserving furnace wall (16), heat-preserving furnace top (12), and vacuum and high-temperature electric heating tube (14). The heat-preserving furnace wall (16) has its inferior part provided with a glass bracket (15); the upper part of the two inner sides with heat-preserving furnace wall are provided with a male tab; the heat-preserving furnace top (12) is fixed on the male tab; the bottom of the heat-preserving furnace top is fixed with a heat-resisting steel made thin baffle board (13); the vacuum and high-temperature electric heating tube (14) is positioned on the inferior part of the heat-resisting steel made thin baffle board (13), with two ends fixed with a head slab arranged on the heat-preserving furnace top. The utility model has the advantages of safety, reliability, large radiation area, even heat transfer, small occupied space in the furnace chamber, easy installation, and convenient maintenance. The utility model not only prevents the entire panel from suffering from a distortion due to a heating but plays a counter radiation role against the heating made to the glass, thereby ensuring a even and rapid heating effect of the heated glass in a clean furnace chamber and meeting the process and quality requirements with comparatively lower energy consumption.
Description
Technical field
The utility model belongs to the technological improvement of various glass heats, moulding, tempering, holding furnace.Relating generally to the anticorrosion shaping sheet of samming radiation half arc multiple-grooved high temperature steel is the composite entity structure of furnace roof internal reflection plate and vacuum high-temperature electrothermal tube.
Background technology
The electrical heating element of existing various glass heats, shaping, tempering, holding furnace and high temperature steel barrier structure thereof be as shown in Figure 1: the main body of electrical heater is made of insulation furnace wall 7 and shell 8 as seen from Figure 1, resistance wire 1 is wrapped in and is lifted on furnace roof 9 tops on the ceramic rod 2, in ceramic rod 2 bottoms heat-resisting steel sheet and plate 4 is set, heat-resisting steel sheet and plate 4 tops are lifted on the furnace roof 9 by suspension rod 3.Be heated glass 5 and enter process furnace owing to the gas that is corrosive in the glass heats burner hearth by glass bracket 6, and resistance wire and ceramic rod expose at roof of the furnace, therefore, corrosion-vulnerable, therefore on-insulatedly again exist potential safety hazard, resistance wire life-span and also shorten, easily powdering away after ceramic rod is corroded to drop on influences the glass surface quality on the sheet glass; Though taked with thickness be δ=4-6mm heat-resisting steel sheet and plate 4 with resistance wire 1 and ceramic rod 2 be heated the measure that glass 5 separates, but because the steel plate that adopts is that flat board and thickness are 4-6MM, exist that self heat storage capacity is big, heat conduction is slow, thermo-efficiency is low, do not stop that still the ceramic powder of small portion and resistance wire oxide skin are shed on glass after the problem, particularly steel plate deformed such as yielding.Because complex structure resistance wire 1, ceramic rod 2, heat-resisting steel sheet and plate 4 and the suspension rod 3 shared burner hearth useful spaces are excessive, increased the thermal capacity of burner hearth simultaneously, energy consumption is bigger, and maintenance is also inconvenient.There are following problem in therefore existing various glass heats, moulding, tempering, holding furnace:
1, resistance wire and ceramic rod are perishable, and the life-span is short, easily powder away and oxide skin is fallen and is heated glass surface, influence the glass surface quality.
2, resistance wire is exposed on-insulated, has potential safety hazard, installation and maintenance inconvenience.
3, heat-resisting steel sheet and plate is dull and stereotyped, and the back that is heated is yielding, and thickness is 4-6MM, self heat storage capacity is big, and thermo-efficiency is low, and heat-resisting steel sheet and plate is a tabular simultaneously, can not guarantee its planeness after the temperature distortion, so just influence thermal-radiating homogeneity, and then also just influence the inner quality of glass.
4, resistance wire, ceramic rod, heat-resisting steel sheet and plate are all hung in furnace roof portion, have taken big quantity space, have increased the electric heating capacity of equipment, the energy consumption height, and thermo-efficiency is low, has increased production cost.
Summary of the invention
The purpose of this utility model provides a kind of radiation formula glass isothermal electrical heater, makes that it has that the electrical heating element insulation safety is reliable, the life-span is long, it is less to occupy furnace cavity, and electrical capacity reduces, and swept area strengthens, characteristics such as thermo-efficiency height.
The purpose of this utility model can adopt following technical scheme to realize: it comprises insulation furnace wall, insulation furnace roof, vacuum high-temperature electrothermal tube, the bottom of insulation furnace wall is provided with glass bracket, the holding furnace of both sides within the walls side be provided with boss, the insulation furnace roof is fixed on holding furnace within the walls on the boss of side, the slim reflector of a high temperature steel is fixed in bottom at the insulation furnace roof, the vacuum high-temperature electrothermal tube is positioned at the slim reflector of high temperature steel bottom, and the cover plate on two ends and the insulation furnace roof is fixed.
Be evenly equipped with the successive arc-shaped slot on the slim reflector of described high temperature steel, the vacuum high-temperature electrothermal tube is positioned at arc-shaped slot.
The slim reflector 3 of half arc shaping high temperature steel described in the utility model is that to adopt thickness be that the heat-resistant anticorrosive stainless steel sheet of 1.5mm is even successive arc groove shape plate by pressure forming, is combined into integral body with heat-stable holding furnace top solder.So both guaranteed that integral panels was heated not yieldingly, and can play counter radiation effect again, and made to be heated glass and in the burner hearth of a cleaning, evenly to be heated fast, and reached with lower energy consumption and satisfy its technology and specification of quality glass heats.Guarantee its quality product and the purpose that cuts down the consumption of energy.Described vacuum high-temperature electrothermal tube is that a kind of shell is the high temperature electric heating tube of heat-resistance stainless steel.Have working temperature and can reach 1000 ℃, work-ing life and improve 2000h, insulation level height (500K Ω) than resistance wire, its have safe and reliable, radiating surface big, conduct heat evenly, occupy characteristics such as furnace cavity Xiao Yi installation, maintenance is convenient.
