Abstract

The utility model relates to a network array type heating glass tempering furnace, which comprises a furnace body, a roller and heating elements; the heating elements are arranged above and below the roller. Blowpipes are arranged between the upper part and/or the lower part of the roller and the heating elements; both ends of each blowpipe are respectively connected with side air pipes which are arranged in both sides of the furnace body; the side air pipes are connected with an air outlet of a high-temperature fan in the furnace body; and the heating elements and the blowpipes are in a network array type structure. The network array type heating glass tempering furnace is characterized in that the blowpipes made of heat resistant steel are in parallel with the conveying roller and vertical to a heating wire to form a network array. A furnace wire conducts radiation heating to the glass and to the adjacent heat resistant steel air pipes, the fan blows the heated air in the furnace into the heat resistant steel pipes, and the hot air is continued to be heated when flowing in the steel pipes and then blown to the surface of the glass to heat the glass; and a glass plate greatly improves the heating speed under two heating methods, i.e. radiation and convection, so that the processed glass has higher quality.

Description

Net configuration heated glass annealing furnace
Technical field
The utility model relates to the glass heats stove of a kind of novel texture and type of heating, specifically is a kind of net configuration heated glass annealing furnace.
Background technology
In traditional glass heats stove, each heating unit evenly is arranged near the upper and lower surface of glass, and heat mainly is delivered to the heating of the surface realization of glass to glass by the radiating mode.Radiation heating is the slowest a kind of mode of conducting heat in conduction, convection current, three kinds of type of heating of radiation, under equal temp of heating element, making glass reach same temperature needs long heat-up time, and heat-up time, length can make the optical quality of glass sustain damage.When being heated glass and being coated glass, owing to there is the one side of rete to have lower radiant ratio, heat is difficult to pass rete to glass heats by the radiating mode, and it is longer that glass reaches the required time of requirement temperature; And the one side that does not have rete so just causes the ununiformity of heat absorption down on glass still with the heat absorption of heat absorption speed faster usually, and the optical quality of the glass after the processing is poorer.
Summary of the invention
The utility model discloses a kind of net configuration heated glass annealing furnace, the rate of heating that prior art exists is slow to solve, the optical quality of the glass after the processing is poor, and the problem of face one side of coated glass heating difficulty.
The technical solution of the utility model is: comprise body of heater, roller-way and heating unit, the two ends rotational support of roller-way is between the body of heater both sides, heating unit is equipped with in above and below at this roller-way, it is characterized in that: above the described roller-way and/or below with heating unit between the blowpipe parallel with described roller-way is housed, be provided with ventilation hole at this blowpipe in the face of a side of roller-way; The two ends of this blowpipe are connected with the sidepiece airduct that is located at inside, body of heater both sides respectively, and this sidepiece airduct is connected with the air outlet that is located at the intravital high-temperature blower of stove; Described heating unit is the netted composition net configuration heating arrangement that intersects with blowpipe.
Described heating unit is made of the nichrome wire that is wrapped on the parent tube.
The adjacent side profile spacing of described heating unit and blowpipe is less than 70mm.
Several described heating units interconnect the composition heating region, at each this heating region temperature regulating device are housed.
The ventilation hole of described blowpipe is evenly arranged, and adjacent ventilation hole is interlaced.
Described high-temperature blower is configured in both sides or the top and the bottom of furnace body inside.
The characteristics that the utility model conducts heat and not influenced by rete according to convective heating are introduced high-temperature blower and blowpipe in process furnace, the blowpipe of heat-resisting steel is parallel with glass conveying roller way, the perpendicular composition net of the heater strip on airduct top battle array.The stove silk carries out radiation heating to glass and high temperature steel airduct, blower fan blasts the air through heating in the stove in the heat resisting pipe, warm air continues to be heated when flowing in steel pipe, then blow to glass surface to glass heats, sheet glass just is under the effect of radiation and two kinds of type of heating of convection current simultaneously like this, has improved rate of heating greatly, simultaneously, the temperature of each heating region all is controllable, makes that heating is more even, and the glass after the processing has higher quality.

Embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises body of heater 1, roller-way 6 and heating unit 3, and the two ends rotational support of roller-way 6 is equipped with heating unit 3 in the above and below of this roller-way 6 between body of heater 1 both sides.It is characterized in that: the blowpipe 4 of heat-resisting steel is housed between described roller-way 6 and heating unit 3, and blowpipe 4 is parallel with described roller-way 6, is provided with ventilation hole at this blowpipe 4 in the face of a side of roller-way 6; The two ends of this blowpipe 4 are connected with the sidepiece airduct 7 that is located at inside, body of heater 1 both sides respectively, and this sidepiece airduct 7 is connected with the air outlet that is located at the intravital high-temperature blower 2 of stove.
Described heating unit 3 is made of the nichrome wire that is wrapped on the parent tube (as porcelain tube).Axially axially mutual vertical with blowpipe 4 of heating unit 3, the profile distance<70mm of an adjacent between the two side.Like this, heating unit 3 has just been formed net battle array heating arrangement as shown in Figure 2 with blowpipe 4.
Several described heating units 3 interconnect (serial or parallel connection) and form a heating region, and the thermopair (not shown) of control Heating temperature is installed at each this heating region.
The ventilation hole of described blowpipe 4 is evenly arranged, adjacent ventilation hole interlaced (not shown).
High-temperature blower 2 is installed in the both sides of body of heater 1, also can be installed in top and bottom.The air suction inlet of high-temperature blower 2 is towards furnace chamber inside, and the air outlet of high-temperature blower 2 links to each other with sidepiece airduct 7.
As required, blowpipe 4 can all be installed in the body of heater top and the bottom form the whole network battle array stove (as shown in Figure 1), also can blowpipe 4 only be installed on the top of body of heater 1 and form half net battle array stove.
