The bottoms of the two brackets are respectively provided with two automatic couplings 14 and automatic decouplings 13. The cold air device is positioned at the upper part of the geosyncline at one side of the left bracket. The utility model has the advantages of small occupation area, simple structure, low investment, high thermal efficiency, uniform furnace temperature, fast heating period and high production yield.

Description

A kind of reciprocating type toughened glass heating unit

The utility model relates to a kind of heating installation, particularly relates to a kind of heating unit of hanging of toughened glass.

Domestic and international existing toughened glass is hung cavity type process furnace and the chain type transmission mechanism mostly heating unit is to adopt three fire doors.Its shortcoming is that the process furnace floor space is big, transmission rig complexity, facility investment height; The area of dissipation of fire door is big, and thermo-efficiency is low, and temperature is wayward in the stove, and glass is heated inequality and easily causes distortion or broken in stove.

The purpose of this utility model is at above-mentioned deficiency, provides a kind of transmission rig simple, and facility investment is low, and heat scatters and disappears few, and furnace temperature is even, thermo-efficiency height, finished product rate height, the reciprocating type toughened glass heating unit that cost is low.

Basic design of the present utility model is by the heat dissipation capacity that reduces process furnace and simplifies transmission rig and realize above-mentioned purpose.Its concrete technical solution is: (1) adopts the pit furnace that a fire door is only arranged at furnace roof; (2) adopt the horizontally tracting machine to drive the to-and-fro movement that process furnace is done level; (3) adopting the vertical distraction machine to drive glass after to be heated or the heating advances stove with vertical movement or comes out of the stove.

Drive mechanism of the present utility model is simple, processing ease.All the plant area area is few, and facility investment is low.The heat dissipation capacity of process furnace is few, thermo-efficiency is high, furnace temperature is even, heating period is short, production efficiency is high, scrap rate is low, facts have proved: compare with the linked transmission heating unit of same specification, area of dissipation of the present utility model can reduce more than 75%, thermo-efficiency improves more than 30%, production efficiency improves 10%, product qualification rate reaching is more than 98%, be to be applicable to that thickness is 3-20mm, area is efficient, the energy-saving heating apparatus of the following various flat curved tempered glasses of 2000 * 3000mm.

Below in conjunction with accompanying drawing, concrete structure of the present utility model and schedule of operation are elaborated.

As shown in Figure 1, the utility model is made up of one group of pit furnace that moves horizontally, vertical lifting mechanism and cooling air unit, wherein:

1, the pit furnace that moves horizontally is seated in the geosyncline 21, and can be under the traction of horizontally tracting mechanism 8, along horizontal guide rail 9 to-and-fro movements.Concrete structure such as Fig. 6, shown in Figure 7 of the heating of well formula:

(1) top, bottom and the periphery between body skin 7 and inner housing 20 is by insulating cotton 19 fillings.Build with heat resisting brick 18 periphery and the bottom of inner housing 20 inwalls; Nichrome wire 17 is housed in the gap of furnace wall heat resisting brick 18.

(2) furnace roof of process furnace has a rectangular fire door 23, and fire door 5 and conventional fire door automatic open close mechanism 16 are housed on the fire door.

(3) guide wheel 11 of process furnace bottom is seated on the horizontal guide rail 9; One end of guide rail 9 is equipped with horizontally tracting machine 8, does reciprocal moving horizontally in order to drive pit furnace.

2, on the crossbeam 22 above the geosyncline 21 longitudinal center positions vertical lifting mechanism is housed, the main body of this vertical lifting mechanism is made up of vertical distraction machine 1 and vertical guideway 2, left tray 12 and right carriage 3.Its concrete structure is as shown in Figure 1:

(1) there are left and right two vertical distraction machines 1 on the top of vertical guideway 2.

(2) both sides of vertical guideway 2 have left tray 12 and right carriage 3 respectively.

(3) two automatic couplings 14 are arranged in the bottom of left tray 12, two automatic releasing hooks 13 are arranged at the bottom of right carriage 3.

(4) glass hanger 4 is and automatic releasing hook 13 and automatic coupling 14 matching used annexes, and two glass frame hooks 15 are arranged at the top of glass hanger 4.

3, a cooling air unit 10 in order to cooling toughened glass is arranged above the geosyncline of left tray 12 1 sides.

Schedule of operation of the present utility model and operation logic are as follows:

1, by horizontally tracting machine 8 pit furnace is urged to the below of right carriage 3, fire door 5 is opened under the driving of stove door switch tractor 16 automatically.

2, glass to be heated 6 usefulness glass hangers 4 are hung on the automatic releasing hook 13 of right carriage 3 bottoms.

3, the right carriage 3 of landing falls into the burner hearth of process furnace with glass 6 by fire door 23, and rises right carriage 3 behind right carriage 3 automatic releasing hooks.

4, fire door 5 is closed automatically, and pit furnace is moved horizontally to the below of left tray 12.

When 5, treating that glass reaches the critical temperature of tempering, (having thermopair to show) falls left tray 12, and after glass hanger 4 was hooked in automatic coupling 14 automatically, fire door 5 was opened automatically, rose left tray 12, and fire door 5 is closed again automatically.

6, air-cooled tempering is carried out in the position that glass 6 is risen to refrigerating unit.

7, according to the cyclical operation constantly of above-mentioned program, work continuously.
