Description

Technical Field

[0001] The utility model belongs to the technical field of glass production, and in particular relates to a closed heat preservation mechanism for an outlet of a C zone of a photovoltaic glass annealing furnace. Background Art

[0002] The production of photovoltaic rolled glass is the process of pressing molten glass into glass plates and annealing it. According to different process requirements, the annealing furnace is divided into A, B, C, D, Ret, E, F1, F2 and other zones from the hot end to the cold end. Among them, zones A, B, and C are closed zones connected together, and zones D, Ret, E, F1, and F2 are transition cooling or open cooling zones. Each area of ​​the closed zone requires a relatively constant temperature, which needs to be controlled by formed hot glass, fans and heaters. The heater is not turned on under normal production conditions. However, when the calender is replaced or the lip brick is replaced, no hot glass enters the annealing furnace. Although the heater is turned on for heating, since there is heat exchange between the outlet of the closed zone, that is, the outlet of zone C, and the cooling zone, the temperature of the entire closed zone cannot rise. Then, when the calender is started and the new hot glass enters the annealing furnace, severe longitudinal cracks will occur, and it will be difficult to return to normal production.

[0003] Therefore, there must be a closed insulation device at the outlet of zone C. Since the temperature at the outlet of zone C is still around 350℃, the device itself needs to be both heat-insulating and fire-resistant. At the same time, since there is a narrow gap between zone C and the cooling zone, the device should be a plug-in structure. Of course, the annealing furnace is nearly 3m high and 3m wide. When the plug-in is inserted from top to bottom, if people go up to the annealing furnace to operate, there will be safety hazards and labor intensity, and the second is to delay the operation time, so it must be easy to operate. Therefore, it is particularly important to design a more suitable closed insulation mechanism for the outlet of zone C. Utility Model Content

It can conveniently achieve the insulation of the furnace cavity in the closed zone of the annealing furnace when there is no hot glass in the annealing furnace and can quickly solve the problem.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

Fastening holes are also provided on the inner and outer panels so that the inner and outer panels can be fastened by locking screws, and the inner and outer panels and the through-tube are fixed by welding.

[0008] Furthermore, the transmission mechanism includes a thin steel wire rope, a pulley, a pulley bracket and a driving device, the pulley is fixed on the pulley bracket, the thin steel wire rope is a long rope and a short rope, one end of the two ropes are connected to two lifting ears through two pulleys respectively, the other end of the short rope is connected to the long rope through two buckles, and the other end of the long rope is connected to the driving device after passing through the pulley.

DETAILED DESCRIPTION

[0022] The utility model of photovoltaic glass annealing furnace C zone outlet closed insulation mechanism, such as Figures 1 to 5As shown, it includes a hanger 1, an insulation sheet 2 and a transmission mechanism 3. The hanger 1 is composed of a hanging beam 103 and a hanging rod 104. Two hanging ears 101 are evenly arranged on the hanging beam 103. The hanging ears 101 are connected to the transmission mechanism 3. Hooks 102 are welded at both ends of the hanging beam 103. The hanging rod 104 is placed on the hooks 102. The insulation sheet 2 includes an inner panel 202 and an outer panel 205. Insulation cotton 203 is filled between the inner and outer panels. A through-tube 201 is provided on the top of the insulation sheet 2. The insulation sheet 2 is penetrated on the hanging rod 104 through the through-tube 201. Fastening holes 204 are also correspondingly opened on the inner panel 202 and the outer panel 205 so that the inner and outer panels are fastened by locking screws. The inner panel 202 and the outer panel 205 are respectively connected to the through-tube The tube 201 is welded and fixed; the transmission mechanism 3 includes a thin steel wire rope 301, a pulley 302, a pulley bracket 303 and a driving device, the pulley 302 is fixed on the pulley bracket 303, one end of the thin steel wire rope 301 is connected to the driving device after passing through the pulley 302, and the other end is connected to the lifting ear 101, the driving device includes a driving gear 304 and a driven gear 306 that are meshed and connected, a driving shaft 305 is passed through the center of the driving gear 304, a driving handle 310 is provided at one end of the driving shaft 305, a driven shaft 307 is passed through the center of the driven gear 306, a single-groove steel wheel 308 is coaxially passed through one side of the driven gear 306, the single-groove steel wheel 308 is connected to the thin steel wire rope 301, and the driving device is also provided with a locking claw 309. The thin steel wire rope 301 consists of two ropes, a long rope and a short rope. One end of the long rope and the short rope are connected to the two lifting ears 101 through two pulleys 302 respectively, and the other end of the short rope is connected to the long rope through two buckles 4, and the other end of the long rope is connected to the single-groove steel wheel 308; the hanging beam 103 and the hanging rod 104 are made of metal pipes, and the hook 102 is made of metal plates; the inner panel 202 is made of fire-proof quartz cloth material, the thermal insulation cotton 203 is rock wool material, the outer panel 205 is made of 3~5mm thick metal plates, and the through pipe 201 is a metal pipe.

[0023] When in use, first assemble the heat preservation mechanism at the exit of the annealing furnace. Figure 6 As shown, first fix the pulley 302 on the top plate of the furnace chamber, pass one end of the long rope of the thin steel wire rope 301 through the pulley 302 and then wind it into the groove of the single-groove steel wheel 308, and the driving device (assembled by the driving gear 304, the driving shaft 305, the driven gear 306, the driven shaft 307, the single-groove steel wheel 308, the stop claw 309, and the driving handle 310) is installed on one side of the outlet 5 of the annealing furnace C zone, where the operator can operate conveniently, the other end of the thin steel wire rope 301 is respectively connected to the lifting ears 101 of the hanger 1, and the hanging beam 103 is suspended, and then several insulation sheets 2 are passed through the hanging rod 104 in turn using their penetration tubes 201. In order to ensure the insulation effect, the sides of each insulation sheet 2 must be tightly attached, and the number of them must be sufficient to close the outlet 5 of the annealing furnace C zone with a margin in the total width, and then the two ends of the hanging rod 104 are hung on the two hooks 102 at the two ends of the hanging beam 103, and the installation is now complete.

[0024] During normal production, the driving handle 310 is rotated clockwise, and the driven gear 304 drives the driven gear 306 to operate, and then the single-groove steel wheel 308 is driven to rotate through the driven shaft 307, so that the thin steel wire rope 301 wrapped thereon lifts the hanger 1 to rise. From the side of the annealing furnace, it can be seen that when the outlet 5 of the C zone of the annealing furnace is opened, the driving handle 310 can be stopped; when the calender or lip brick is replaced, there will be a period of time when no hot glass enters the annealing furnace. At this time, in addition to turning on the heater, the driving handle 310 needs to be rotated clockwise. Under the action of gravity, the hanger 1 and the insulation sheet 2 are hoisted down by the thin steel wire rope 301, and the outlet 5 of the C zone of the annealing furnace is closed, and the closed area of ​​the annealing furnace is insulated to ensure that when the calender starts to operate and hot glass enters the annealing furnace, there is a normal temperature environment.

[0025] In summary, the use of the insulation mechanism of the utility model can not only achieve stable control of the temperature of the closed area of ​​the annealing furnace when there is no hot glass during the replacement of the calender and the lip brick, but also facilitate operation, save time and reduce safety hazards.
