Description

Technical Field

[0001] The utility model belongs to the technical field of tempering furnace equipment, and in particular relates to an air grid pressure boosting device of an energy-saving fireproof tempering furnace. Background Art

[0002] Glass tempering furnace, also known as glass tempering equipment, is an industrial heating and quenching combined process equipment. Glass tempering furnace uses physical methods to form a tensile stress layer inside the glass and a tensile stress layer on the surface; when the glass is subjected to external force, the tensile stress layer can offset part of the tensile stress to prevent the glass from breaking, thereby achieving the purpose of improving the strength of the glass. Not only that, the micro cracks on the surface of the glass become more subtle under this tensile stress, which also improves the strength of the glass to a certain extent.

[0003] Glass tempering furnaces generally include a heating furnace body and a cooling device. After the glass is heated by the heating furnace body, it enters the cooling device for cooling. The cooling device blows cold air to the glass plate through the cooling air grid located on the upper and lower sides of the glass plate to cool the glass plate.

If you want to achieve the tempering effect, you need to drive a large air supply device, which will consume a huge amount of energy. Therefore, in order to achieve strong cooling, the existing air supply equipment must be modified. Utility Model Content

[0027] See also Figure 1 and Figure 2 An embodiment of the utility model provides a wind grid pressurization device for an energy-saving fireproof tempering furnace, comprising a pressurization duct 1 and a wind grid box 2, wherein the wind grid box 2 is provided with a plurality of groups along the length direction of the glass, the pressurization duct 1 is arranged in the wind grid box 2, and a wind grid nozzle 3 is arranged on the wind grid box 2; the pressurization duct 1 comprises a plurality of independent control sections, each of which is provided with a pressurization nozzle 4, and the pressurization nozzle 4 is arranged in the wind grid nozzle 3, so that the high-pressure gases in the pressurization nozzle 4 and the wind grid nozzle 3 are mixed and sprayed onto the glass surface at the same time.

[0028] In this embodiment, the booster pipe 1 is arranged in the wind grid box 2, so that the high-pressure gas in the booster pipe 1 is mixed with the high-pressure gas in the wind grid box 2, and then sprayed to the glass surface at the same time, achieving the effect of boosting. The wind grid nozzle 3 is provided with a plurality of spray holes, the spray hole located in the middle is used to spray out the separate airflow of the wind grid box 2, and the spray holes located on both sides of the middle spray hole are used to spray out the mixed airflow 8 of the wind grid box 2 and the compressed air. At the same time, the booster pipe 1 includes a plurality of independent control sections, which can control the opening or closing of the corresponding booster pipe 1 according to the width of the glass, thereby saving energy.

[0029] In this embodiment, an independent solenoid valve and a pressure regulating valve are provided for each independent control section in the boosting pipeline 1. Each independent control section is controlled by a separate solenoid valve and a pressure regulating valve, and has flexible operation and strong controllability.

[0030] In this embodiment, an infrared thermometer 5 is provided in the independent control section at the corresponding position in the boosting pipeline 1. When the glass starts to come out of the furnace after heating and enters the wind grid box 2 for quenching and tempering, the infrared thermometer 5 at the boosting pipeline 1 is used to detect the temperature of the glass, and the outlet pressure of the boosting pipeline 1 behind is adjusted according to the temperature.

[0031] In this embodiment, the pressurizing pipe 1 is arranged along the width direction of the glass, and at least two independent control sections are arranged in the width direction of the glass, preferably three independent control sections, more preferably four independent control sections, or more independent control sections can be arranged as needed.

[0032] The booster pipe 1 of the utility model is composed of multiple independent control sections, and is provided with independent solenoid valves and pressure regulating valves. Each section of the booster pipe 1 corresponds to a glass of a certain width. When the width of the glass is very large, the solenoid valves of the booster pipe 1 are all opened. When the width of the glass is very small, the corresponding booster pipe 1 is opened, and the booster pipes 1 in other non-glass areas are closed and in a non-working state, thereby greatly reducing energy.

[0033] In the present invention, a corresponding infrared thermometer 5 is arranged in the boosting pipe 1 at the corresponding position. When the glass starts to be taken out of the furnace after heating is completed and enters the wind grid box 2 for quenching and tempering, the glass is first quenched by the mixed gas of the two wind grid boxes 2, and then the temperature of the glass is detected by the infrared thermometer 5 arranged at the boosting pipe 1. For the high temperature area, the pressure of the electromagnetic valve at the corresponding boosting pipe 1 is increased by the pressure regulating valve, and for the low temperature area, the pressure of the electromagnetic valve at the corresponding boosting pipe 1 is reduced by the pressure regulating valve, so as to achieve the purpose of making the cooling speed of the glass the same over the width, making the stress of the glass the same over the width, thereby increasing the fire resistance time of the fireproof glass and reducing the probability of the glass self-explosion.

[0034] In this embodiment, the number of the independent control sections is 3, and a booster nozzle 4 is provided. Preferably, more independent control sections can be provided as needed, and corresponding booster nozzles 4 are provided. The booster pipe 1 of the present application is provided with several independent control sections in the glass width direction to form independent control groups in the glass width direction, and several groups of independent control groups are provided in the glass length direction, and each independent control section is provided with multiple booster nozzles along the glass length direction, see Figure 3 , Figure 3 In the middle is a booster nozzle 4 of another structure, which is arranged above the wind grid nozzle 3. The high-pressure gas in the booster nozzle 4 enters the wind grid nozzle 3 to form a mixed airflow 8 and blows toward the glass surface together.

[0035] In this embodiment, the boost nozzle 4 is fixed to the positioning groove 9 of the wind grid nozzle 3 by screws 6, and the boost nozzle 4 is provided with a plurality of guide air nozzles 7 facing the wind grid nozzle, so that the high-pressure mixed air blowing toward the glass surface is more uniform. In another preferred embodiment, the boost pipe 1 can also form a nozzle by punching holes.

[0036] In this embodiment, the boosting pipeline 1 is connected to the air storage tank at the air compressor.

[0037] In this embodiment, the quenching air of the wind grid box 2 comes from a centrifugal fan.

[0038] The working principle of the utility model is as follows: during the production process of the tempering furnace, the glass is heated by the furnace body and enters the wind grid for quenching and cooling to achieve the purpose of tempering. The boosting pipeline 1 is composed of multiple sections, each of which is provided with an independent solenoid valve and a pressure regulating valve (for easy individual switching and pressure regulation), and a corresponding infrared thermometer 5 is provided in the boosting pipeline 1 at the corresponding position. After the glass is heated, it starts to come out of the furnace and enters the wind grid for quenching and tempering. The glass first passes through two wind grid boxes 2 for quenching, and then the infrared thermometer 5 at the boosting pipeline 1 is used to detect the temperature of the glass. For the high temperature area, the pressure of the corresponding solenoid valve at the boosting pipeline 1 is increased by the pressure regulating valve, and for the low temperature area, the pressure of the corresponding solenoid valve at the boosting pipeline 1 is reduced by the pressure regulating valve, so that the stress of the glass in the width is the same, thereby increasing the fire resistance time of the fireproof glass and reducing the probability of the glass self-explosion.

[0039] Because the booster pipe 1 is multi-stage independently controlled, the booster pipe 1 of the corresponding length can be opened according to the width of the glass for pressurized blowing. The booster pipe 1 in the non-glass area is in a closed state, which greatly saves the air source and reduces the energy consumption generated during glass tempering.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
