TECHNICAL FIELD

RELATED ART

Glass materials are widely used in daily life, for example, applied to building materials to serve as interior decoration glass or window glass, or applied to electronic devices to serve as panels of displays or protective glass of mobile phones.

After the glass is made, a series of heat treatment processes must be performed to adjust the mechanical properties of the glass. For example, the annealing process is to slowly heat the glass to above the annealing temperature for a period, and then to gradually cool the glass to make the glass have a specific shape. Therefore, the stress of the glass can be eliminated to prevent the glass from breaking easily when it is impacted. Further, the tempering process is to first heat the glass to 600 degrees Celsius, and then use high-pressure air to impact on the glass surface and rapidly cool the glass to 300 degrees Celsius for quenching, such that compressive stress is generated on the glass surface to increase the hardness of the glass surface and to strengthen the glass surface. Finally, the tempering process is to gradually cool the glass cool to room temperature.

Current quenching is to produce airflow by using an airflow generation source, then to make the airflow enter a wind box, and next to make the airflow enter heat treatment units from the wind box. When the flow speed of the air is needed to be changed to adjust the wind pressure, the flow of the airflow generated by the airflow source must be changed, that is, Q=Av, wherein Q is the flow of the airflow, A is the cross-sectional area of the wind box, and v is the flow speed of the airflow. When the cross-sectional area A of the wind box was fixed, to change the flow speed v, it is necessary to change the flow Q of the airflow. However, to change the flow of the airflow, it requires to increase the driving force of the airflow source, such as changing the speed of the fan, which will increase power consumption.

DETAILED DESCRIPTIONS OF EXEMPLARY EMBODIMENT

While embodiments are described herein by way of example for multiple embodiments and illustrative drawings, those skilled in the art will recognize that embodiments are not limited to the embodiments or drawings described. It is noted that, drawings and detailed descriptions thereto are not intended to limit embodiments to the specific implementations disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope as defined by the appended claims.

Refer to FIG. 1 and FIG. 2, and both of FIG. 1 and FIG. 2 relate to an embodiment of a plate heat treatment device provided by the present disclosure. In the embodiment, the plate heat treatment device 1 comprises a high-pressure hardening reaction module 10 and a low-pressure cooling module 20. After the plate is heated to about 600 degrees Celsius, the plate passes through high-pressure hardening reaction module 10 and low-pressure cooling module 20 in sequence. The plate in the high-pressure hardening reaction module 10 is quickly cooled down to 300 degrees Celsius for quenching by using the high-pressure airflow, stress of a surface of the plate is thus enhanced to increase hardness of the plate, such that the strengthening effect on the plate is achieved. The plate after the quenching process is cooled down by using a low-pressure airflow in the low-pressure cooling module 20.

In the embodiment, the high-pressure hardening reaction module 10 comprises a wind pressure adjustment device 11 and multiple pairs of first heat treatment units 12. The multiple pairs of the first heat treatment units 12 are disposed on the wind pressure adjustment device 11. The wind pressure adjustment device 11 comprises a first air source 111 and a wind speed adjustment chamber 112. The first air source 111 is configured to generate a first airflow with a predetermined flow. The wind speed adjustment chamber 112 has a volume being variable and comprises a first air inlet 1121 and multiple first air outlets 1122. The first air source 111 is communicative to the first air inlet 1121. The first air source 111 can be a blower, and the first airflow is generated by a fan or an impeller. The first airflow has a predetermined flow, and the first airflow enters the wind speed adjustment chamber 112 from the first air inlet 1121.

The first air inlet 1121 and the first air outlet 1122 are disposed on the chamber 1123. The gates 1124 are arranged in parallel, and line up in a row from the first air inlet 1121 to far. Each of the gates 1124 can move into the chamber 1123 to close a cross section of the chamber 1123, such that the volume of the chamber 112 into which the first airflow flows can be variable. Thus, the cross-sectional area of the first air outlet 1122 corresponding to first airflow is variable. Since Q=Av, i.e., the flow Q is equal to the product of the cross-sectional area A and the flow speed v, by making the gates 1124 at various positions move into the chamber 1123, the cross-sectional area A of the first air outlet 1122 corresponding to first airflow is variable. In the case of the same flow Q of the first airflow, the cross-sectional area A is inversely proportional to the flow speed v of the first airflow. The cross-sectional area A in FIG. 6 is larger than the cross-sectional area A in FIG. 7, and thus the flow speed v of the first airflow in FIG. 6 is less than the flow speed v of the first airflow in FIG. 7, such that the wind pressure which the first airflow impacts on the plate P can be adjusted.

The first airflow enters the multiple pairs of the first heat treatment units 12 through the first air outlets 1122. As shown in FIG. 3 to FIG. 5, the multiple pairs of the first heat treatment units 12 are respectively communicative to the first air outlets 1122 of the wind speed adjustment chamber 112.

The multiple pairs of the first heat treatment units 12 are arranged in a row. A plate P is conveyed to pass through the gap G1 between the first upper heat treatment unit 12 and the first lower heat treatment unit 12 of each pair of the first heat treatment units 12, and the plate P is supported and driven by the rollers R to move.

The chamber 1123 is disposed with multiple entrances 1126, the gates 1124 can move into the chamber 1123 from the entrance 1126. When the gate 1124 moves away from the chamber 1123, the gates 1124 move to the housings 1125 and received in the housings 1125.

The wind speed adjustment chamber 112 comprises multiple guide frame units 1127, each of the guide frame unit 1127 is formed by a pair of guide frames 1128, and the pair of guide frames 1128 comprises a left guide frame 1128 and a right guide frame 1128. The paired guide frames 1128 (i.e., the left guide frame 1128 and the right guide frame 1128) have a spacing G2, and when the gate 1124 moves into the chamber 1123, the gate 1124 passes through the spacing G2 between the paired guide frames 1128. Each of the guide frames 1128 has a hollow part 1129, and the hollow part 1129 makes interior of the chamber keep communicative when the gate 1124 does not move into the chamber 1123.

The wind speed adjustment chamber 112 comprise multiple airtight parts 1130, and the airtight parts 1130 are disposed in the spacing G2 between the paired guide frames 1128. Each of the airtight parts 1130 corresponding to the paired guide frames 1128 are disposed opposite to each other, and when the gate 1124 passes through the spacing G2 between the paired guide frames 1128, the gate 1124 contacts the airtight parts 1130, such that the air in the chamber 1123 will not leak from the entrance 1126.

The low-pressure cooling module 20 comprises a second air source 21, an airflow chamber 22 and multiple pairs of second heat treatment units 23. The second air source 21 generates a second airflow with a predetermined flow. The airflow chamber 22 is connected to the wind speed adjustment chamber 112, and has a volume being variable.
