A new type of exhaust heating device for photovoltaic glass production

Abstract

Provided is a novel fire discharging and heating device for photovoltaic glass production. The fire discharging and heating device is mainly composed of a fire discharging and heating gun, suspension devices and supports. The fire discharging and heating gun comprises connecting rods, burners and chain connecting pieces. Each suspension device comprises a suspension chain and a special crossbeam. Each support comprises a movable pedestal, a fixed rod, a movable rod, a first locking top thread, a clamping device and a second locking top thread. When the fire discharging and heating gun is used, the fire discharging and heating gun is placed to an appropriate height downward vertically through the suspension chains. When the supports are used, the supports are arranged under the connecting rods of the fire discharging and heating gun, and one support is arranged on the left and one support is arranged on the right. The connecting rods of the fire discharging and heating gun are fixed in U-shaped slots of the U-shaped clamping devices of the supports. the height of the fire discharging and heating gun is adjusted up and down through telescopic movement of the movable rods in the fixed rods. The burners of the fire discharging and heating gun are subjected to any angular adjustment through the U-shaped clamping devices of the supports, and the uniformity of flame intensity can be raised. Rapid erection and remove of the fire discharging and heating device are achieved, and the fire discharging and heating device has advantages of simple structure, convenient usage and good effects.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic glass production, in particular to a novel exhaust heating device for photovoltaic glass production. Background technique [0002] At present, in the production of solar photovoltaic glass in my country, when replacing lip bricks and calenders, it is necessary to use a gate plate to block the glass liquid flowing out of the melting channel. After the glass liquid is blocked, the glass liquid on the outer edge of the lower end of the gate plate is quickly cooled. To solidify, when re-leading the plate, it is necessary to lift the gate plate to a certain height. Before lifting the gate plate, use a fire heating device to heat and melt the solidified glass at the lower edge of the gate plate and its surroundings. The currently widely used exhaust heating device has the following disadvantages: 1. The shape of the heating nozzle is mostly cylindrical, and the flame intensity is uneven; 2. Th...

AI Technical Summary

Problems solved by technology

The currently widely used exhaust heating device has the following disadvantages: 1. The shape of the heating nozzle is mostly cylindrical, and the flame intensity is uneven; 2. The exhaust heating gun does not use a chain suspension device, which is inconvenient to erect; 3. The exhaust heating The angle of the gun flame, the vertical height and the horizontal distance from the gate plate cannot be adjusted at the same time, and the rapid melting of the solidified glass at the outer edge of the lower end of the gate plate and its surroundings cannot be realized.
