Referring to fig. 1 to 3, a forced convection apparatus for improving productivity of double-silver LOW-E glass includes a first convection assembly 20 and a second convection assembly 30 connected to a high temperature fan 10, wherein the first convection assembly 20 and a plurality of second convection assemblies 30 are respectively disposed above and below a wire 40; the first convection assembly 20 and the second convection assembly 30 are symmetrically arranged in the width direction in the toughened hearth, air pipes are respectively arranged at the two ends of the high-temperature fan 10 along the toughened hearth, and the first convection assembly 20 and the second convection assembly 30 are connected with the air pipes so that hot air is blown from the two ends to the middle.
Specifically, the first convection assembly 20 includes a first convection tube 21 and a plurality of first nozzles 22, and the first nozzles 22 are connected to the first convection tube 21 and disposed downward through the gaps of the wires 40; the second convection assembly 30 comprises a second convection tube 31 and a plurality of second nozzles 32, the second nozzles 32 are connected with the second convection tube 31 and arranged downwards, holes 33 penetrating through the second convection tube 31 vertically are formed in the second convection tube 31, round tubes 34 are welded with the second convection tube 31 in the holes 33, and the first nozzles 22 are inserted into the round tubes 34. In use, the first nozzle 22 and the second nozzle 32 simultaneously perform forced convection heating on the upper surface of the glass, thereby improving the heating rate and productivity of the glass.
The length of the first nozzle 22 is longer than that of the second nozzle 32, the lengths of the first nozzle 22 and the second nozzle 32 can be arbitrarily selected according to the requirement, and the second nozzle 32 is arranged at the gap between the first nozzles 22. The first nozzles 22 penetrate through the gaps between the adjacent furnace wires 40 and the second convection tubes 31 below the furnace wires 40 to blow air to the surface of the glass, and the blown air is close to the upper surface of the glass, so that the maximum utilization of heat energy is achieved, energy sources are saved, and the production efficiency is improved. The direction of blowing the second nozzle 32 is positioned at the gap which is not reached by the first nozzle 22 on the furnace wire 40, so that the blind area which is not reached by the first nozzle 22 on the furnace wire 40 is made up, the uniform distribution of heat energy to the glass heating is achieved, the flatness of the glass is smoother, and the wind spots formed by the uneven heating of the glass are reduced.
The first convection tube 21 and the second convection tube 31 are arranged above the gap of the quartz roller way 50 in parallel, and the wind blown by the first nozzle 22 and the second nozzle 32 faces the gap of the quartz roller way 50. Overheating of the quartz roller table 50 is avoided so as not to burn the lower surface of the glass. Preferably, the first nozzle 22 and the second nozzle 32 are both angled toward the glass. The first nozzles 22 are arranged at the gap of every two furnace wires 40 and blow to the furnace wires 40 at a certain angle, so that the gas field of high-temperature gas in the heating furnace blows to the upper surface of the glass from top to bottom, the high-temperature gas is prevented from overflowing to a large extent, and the waste of heat energy sources is avoided.
The convection tube can be made of high-temperature resistant stainless steel or high-temperature resistant ceramic, and is symmetrically arranged in the width direction in the hearth, so that deformation caused by too long convection tube is reduced to a large extent; the convection tube is provided with a diversion nozzle (the length of the diversion nozzle can be selected according to actual needs), so that high-temperature wind has diversion property, wind bundles are more concentrated, and high-temperature wind pressure is concentrated and blown to the upper surface of glass.
Further, the first convection tube 21 and the second convection tube 31 have an equal diameter structure, i.e. the diameters of the two ends of the convection tubes are identical. The convection tube is designed into an equal diameter mode, so that the pressure of wind blown out from a nozzle of the convection tube is gradually increased from the end part to the tail section, and the large-layout glass is convenient to process.
Further, the first convection tube 21 and the second convection tube 31 have different diameter mode structures, i.e. the diameter of the convection tube gradually decreases from one end to the other end. The convection tube is designed into a different diameter mode, so that the pressure of wind blown out from the nozzle of the convection tube is the same, the convection tube is very uniform, and the convection tube is very suitable for the working condition of mixing large glass and small glass.
In the production process of the toughening furnace, glass goes forward to a sheet feeding roller way of the glass after the previous working procedure, and enters a hearth for heating; the high-temperature fan is started in the heating process, so that the two convection pipe nozzles on the upper part and the lower part of the furnace wire heat glass simultaneously, the convection nozzles of the two convection pipes mutually compensate the blind areas of each other, the purpose of heating each area on the width of the glass is achieved, and the requirements of no wind spots and flatness of the glass are ensured.
After the glass is heated, the glass enters the quenching air grid through the quartz roller way to be tempered and quenched, so that the purpose of tempering the glass is achieved. After the blowing is completed, the glass enters the lower sheet table to wait for manual or mechanical hand to unload sheets, and the process is repeated repeatedly.
The foregoing description is only illustrative of the present application and is not intended to limit the scope of the application, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present application.
