Problems solved by technology
The air grid in this structure has been working in a high-temperature environment for a long time, and its own temperature is high, which leads to an increase in the temperature of the cold air conveyed inside, and the final blown air temperature is high, and the tempering effect on the glass is not good; the structure of the air grid bar The volume is large, occupying a certain space, and the volume of the inner cavity of the air inlet box used to transmit cold air is also large, which may easily lead to insufficient internal pressure and affect the effective width of glass tempering. Loud noise and no recovery of heat energy
[0003] At present, the thickness of traditional tempered glass in the industry is greater than 3.2mm, and the effective glass tempering width is not greater than 1800mm. The power of the fan in the high-pressure tempering section (passing section) is more than 500kw, which has high energy consumption and noise greater than 110 decibels. The noise is large and affects the surrounding environment.

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] see Figure 1-Figure 10 , the air grid system combined with liquid cooling and air cooling includes several air grid bars 15 arranged side by side, and adjacent liquid cooling channels and air cooling channels 15.5 are arranged on the air grid bars 15; A liquid inlet 15.1 and a liquid outlet 15.2 connected to the liquid cooling channel are respectively provided. The cooling liquid enters the liquid cooling channel from the liquid inlet 15.1, and leaves from the liquid outlet 15.2 after exchanging heat with the air grid bar 15 to cool down; the air grid bar 15 Corresponding to the air cooling channel 15.5, there is an air inlet 14.1 and several air outlet nozzles 15.6. The cooling air enters the air cooling channel 15.5 from the air inlet 14.1, and then sprays out to the glass a through the air outlet 15.6 to achieve the tempering effect. By addi...

Abstract
The invention relates to a wind grating system capable of combining liquid cooling and air cooling. The wind grating system comprises wind grating strips, wherein each wind grating strip is provided with a liquid cooling channel and an air cooling channel which are adjacent to each other; each wind grating strip is provided with a liquid inlet and a liquid outlet corresponding to the corresponding liquid cooling channel, and cooling liquid enters each liquid cooling channel from the corresponding liquid inlet and then leaves from the liquid outlet after cooling the corresponding wind grating strip by means of heat exchange; each wind grating strip is provided with an air inlet and a plurality of air outlet nozzles corresponding to the corresponding air cooling channel, and cooling air enters each air cooling channel from the corresponding air inlet and is then sprayed to glass via the air outlet nozzles; therefore, a tempering effect is achieved. The wind grating system is good in glass tempering effect, high in efficiency, large in effective tempering width and low in noise. A glass tempering furnace comprises an air cooling system, a liquid cooling system and the wind grating system; the air cooling system comprises an air compressor, a cold dryer and a compressed air tank. The wind grating system solves the problem of difficultly tempering ultrathin and super-wide tempered glass of a toughening furnace unit, the thickness of the tempered glass can be as low as 2.5-3mm, is in accordance with standards in China, and meanwhile, the effective glass tempering width can reach up to 1800-2800mm.
Description
technical field [0001] The invention relates to an air grid system on a glass tempering furnace, in particular to an air grid system combined with liquid cooling and air cooling and a glass tempering furnace equipped with the system. Background technique [0002] Chinese Patent Document No. CN203346265U disclosed an improved glass tempering furnace air grid system on December 18, 2013, specifically disclosing two box-shaped air grid assemblies arranged above and below the air grid drive roller, each air grid The grid assembly is composed of a plurality of air grid bars, and each air grid bar is composed of an air inlet box and an air outlet nozzle. The air outlet nozzle extends along the length of the air inlet box and is connected to one side of the air inlet box and The inner cavity of the air inlet box is connected, and the air outlet nozzle is provided with an independent cold air passage along the length extension direction. A plurality of cold air outlet holes and col...
