Problems solved by technology

This technical solution adjusts the surface temperature of the ceramic roller through cold air pipes and cold air nozzles, which leads to large energy loss and difficult adjustment and control.
[0005] Invention patent application 200410046386.6 discloses a convective glass plate heating furnace, which includes a furnace body with a glass plate inlet and outlet, a glass plate conveying mechanism in the furnace body, and a high-temperature gas injection device in the furnace body. The high-temperature gas injection device, the fan form a gas circulation loop through the pipeline and the inner cavity of the furnace, and a flame radiant tube heater is arranged on the air flow channel between the high-temperature gas outlet on the high-temperature gas injection device and the fan. This technical solution solves the problem of The disadvantage of uneven heating, but the fan is installed outside the furnace body, the heat inside the furnace body will be lost due to the air flow between the inside and outside of the furnace body, resulting in waste of resources

Embodiment Construction

[0026] Such as figure 1 , 2 As shown, an energy-saving strong convection flat glass heating furnace includes a furnace body 1. The furnace body 1 is composed of a liftable upper furnace body 2 and a lower furnace body 3 fixed on the ground. The inner walls of the furnace body 1 are provided with insulation layers. 17. The furnace body 1 is provided with a glass plate inlet furnace door 4 and an outlet furnace door 5. The furnace body 1 is provided with a ceramic roller table 16 for conveying flat glass 15. The furnace body 1 is provided with several groups of temperature-resistant furnaces arranged symmetrically up and down. Windmill 6, the air outlet 9 of each temperature-resistant windmill 6 communicates with the corresponding pipeline. The pipe 10 is connected with several branch air pipes 12 through the flexible suspension mechanism 18. Both the upper and lower air pipes are distributed symmetrically above and below the ceramic roller table 16 facing the ceramic roller ta...

Abstract

An energy-saving plate glass heating furnace with strong convection is composed of a furnace body consisting of the life upper half and the lower half fixed to ground and with glass plate inlet and outlet gates, several groups of upper and lower refractory blowers, the upper and lower pipelines with the inlets connected to the air outlets of blowers and outlets to generate strong convection, the primary heaters at the air inlets of said blowers, and the secondary heaters at the air outlets of said pipelines.

Description

technical field [0001] The invention relates to a heating furnace specially used for glass tempering equipment, in particular to a heating furnace with electric heating as the heat source, hot air convection as the main heat transfer mode, and ceramic roller conduction and steel surface heat radiation as the heating furnace. Auxiliary heat conduction mode flat glass heating furnace. Background technique [0002] At present, the glass plate heating furnaces on the market are all based on radiation heating, supplemented by conduction heating on the lower surface of the glass plate by the surface of the ceramic roller table. Since the glass plate must move back and forth on the roller table, the conductive heating of the surface of the ceramic roller table to the lower surface of the glass plate must exist, and the amount of heat conduction is not controlled. The so-called radiation heating is to use the infrared light emitted by the electric heating wire to directly radiate t...
