Description

A kind of rotary type curved tempered glass process furnace

The utility model relates to a kind of heating installation; Particularly relate to the rotary type process furnace that a kind of toughened glass adds thermal distortion.

At present, curved tempered glass process furnace both domestic and external, great majority adopt tunnel type furnace body, and are transmitted by the horizontal transmission rig of linear pattern.This process furnace is because of the body of heater both ends open, and it is serious to cause heat to scatter and disappear, thereby thermo-efficiency is on the low side, and the huge and transmission rig complexity because of body of heater again, so cost is higher, and operation inconvenience, furnace temperature is difficult to control, more is not easy to maintaining.

The purpose of this utility model is at above-mentioned defective, provides a kind of simple in structure, and cost is low, and the thermo-efficiency height is easy and simple to handle, and furnace temperature is easy to control, can satisfy many kinds, efficient, the energy-conservation rotary type curved tempered glass process furnace of production in enormous quantities.

The purpose of this utility model mainly realizes by following technical measures: (1) process furnace adopts the unitized construction of square casing and spherical hearth; (2) traversing mechanism of one group of glass ware forming mould is housed in spherical hearth, makes glass state hot briquetting with turning motion in stove; (3) fire door of input and output material is located at a side of body of heater, and seals fire door with fire door, is beneficial to reduce heat and scatters and disappears.

Type of furnace novelty of the present utility model, transmission rig are simple, heat scatters and disappears less, the thermo-efficiency height, with short production cycle, product percent of pass is high.Experiment showed, that facility investment instrument of the present utility model is about 20% of a conventional equipment, heating rate improves about 25%, and product percent of pass can reach more than 98%.

Fig. 1 is the main pseudosection of the utility model embodiment one;

Fig. 2 is that the A-A of the utility model embodiment one is to sectional view;

Fig. 3 is the main pseudosection of the utility model embodiment two;

Fig. 4 is that the B-B of the utility model embodiment two is to sectional view.

Below in conjunction with accompanying drawing, specific embodiment and the operation logic of two embodiment of the present utility model is elaborated.

Embodiment one (with reference to figure 1-Fig. 2): the top between (1) dual circular inner shell 14 in process furnace square casing 13, all use insulating cotton 1 filling in bottom and the peripheral clearance, the inwall of circular shell 14 then is built into spherical hearth 6 by heat resisting brick 15; (2) in the gap of burner hearth 6 bottom surface heat resisting bricks nichrome wire 16 is housed; The outstanding dress of the end face of burner hearth 6 nichrome wire 16; (3) heat resisting brick of burner hearth 6 bottom surfaces and be covered with one deck stainless steel plate 18 above the nichrome wire 16; (4) the outstanding traversing mechanism of adorning one group of glass ware forming die in spherical hearth 6, this traversing mechanism is that a rotating shaft 2 that is driven by revolution driving machine 3 is arranged at the center of furnace roof, there is a pedestal 12 bottom that rotating shaft 2 probes in the burner hearth 6, the carriage 5 of two radiation-like is housed on the pedestal 12 at least, all installs a glass ware forming die 4 on each carriage; (5), a fire door 7 that leads to spherical hearth 6 is arranged and in order to the fire door 8 of sealing fire door in a side of process furnace square shell body 13.

Square shell body 13 and circular inner shell 14 in the said structure are all selected steel plate forming for use, and rotating shaft 2, pedestal 12, carriage 5 and glass ware forming die are all selected the heat-resisting alloy steel manufacturing for use.

The sequence of control and the operation logic of present embodiment are as follows: (1) opens fire door 8, and glass 9 is placed on the glass ware forming die 4 by fire door 7; (2) close fire door 8, driving mechanism 3 drive traversing mechanisms revolve to turn 90 degrees and stop; (3) open fire door 8 again, close fire door 8 after putting into second block of glass; (4) repeat above-mentioned circulation, glass is the rotating while in burner hearth, and is softening and take shape in gradually in the die 4 by self gravitation because of glass heats; (5) when glass returns back to fire door 7, open fire door 8, take out in type glass, and put into new glass; (6) more than the working continuously that so circulate.

(referring to Fig. 3-Fig. 4): the overall structure of present embodiment and embodiment one are basic identical for embodiment two, the key distinction is: (1) is except that the side at square casing has a charging fire door 7 and fire door 8 that leads to burner hearth, adjacent side in these fire door up time rotation 270 degree directions also has a discharging fire door 10 and a fire door 11 that leads to burner hearth 6 on the body skin; (2) on the burner hearth end face of discharging fire door 10 1 sides, install a glass ware forming punch 17, just to be still in the position of discharging fire door 10 corresponding with die 4 in the position of this punch; (3) the outstanding slewing lifting mechanism of adorning one group of glass ware forming die in the center in the burner hearth 6, the rotating shaft 2 of this slewing lifting mechanism can be driven by horizontal rotation that is positioned at furnace roof and lifting driving mechanism 3 and do horizontal rotation and oscilaltion campaign.

The schedule of operation of present embodiment is also identical with embodiment one basically with operation logic, difference is: (1) is when slewing lifting mechanism revolves three-sixth turn, driving glass ware forming die 4 by slewing lifting mechanism moves up, and coincide with glass ware forming punch 17, to the shaping of pressurizeing of in type glass; (2) after the pressurization shaping, the slewing lifting mechanism original position that falls back, from the in type glass of discharging fire door 10 taking-ups, slewing lifting mechanism up time again revolves and turn 90 degrees, and opens charging fire door 8, and glass to be heated 9 is put on the die 4, closes charging fire door 8; (3) work continuously so circularly.

The utility model can be applicable to thickness 3-8mm according to the change of body of heater size, and area is at 3m ²The curved tempered glass hot briquetting in enormous quantities of following all size.
