[0025] Example one,

[0026] In order to more clearly describe the specific structure composition of the air flow stabilizing equipment for toughened glass cooling, combining the attached Figure 1 Describe this embodiment:

[0027] As attachedFigure 1 As shown, an airflow stabilization device for cooling tempered glass includes a heating furnace 1, a cooling section 4 and a conveying roller 5, and is characterized in that an isolation baffle assembly is provided between the cooling section 4 and the heating furnace 1, and the isolation baffle assembly, the cooling section 4, the heating furnace 1, and the ground 6 together constitute a flow field space for stabilizing the airflow, and the conveying roller 5 passes through the flow field space and the cooling section 4 by the heating furnace 1, and the isolation baffle assembly is composed of a windshield 3 and a sealing plate 2.

[0028] In this embodiment, one end of the wind shield 3 is fixed to one side of the heating furnace 1, and the other end is provided with a fixing hole for fixing the sealing plate 2. One end of the sealing plate 2 is connected to the wind shield 3 through the fixing hole, and the other end is in contact with the cooling section 4 to form a flow field space.

[0029] The sealing plate 2 is made of a high-temperature resistant soft material, such as ceramic glass fiber cloth, which can effectively block the airflow without affecting the lifting action of the cooling section 4.

[0030] When the upper and lower bellows 8 of the cooling section 4 begin blowing air, the downward airflow from the upper bellows 8 is blocked by the floor 6, forming a specific airflow field section below the conveyor roller 5. The upward airflow from the lower bellows 8 is blocked by the windshield 3, forming a specific airflow field section above the conveyor roller 5. In this way, when the glass 7 enters the cooling section 4 from the heating furnace 1 under the action of the conveyor roller 5, the upper and lower surfaces of the glass 7 are in a substantially similar airflow environment, which helps to achieve balanced temperature control on the upper and lower surfaces of the glass 7, thereby improving the flatness and quality of the glass.

[0031] Example 2

[0032] In order to more clearly describe the specific structural composition of the airflow stabilization device for tempered glass cooling, Figure 2 Describe this embodiment:

[0033] As attached Figure 2 As shown, an airflow stabilization device for cooling tempered glass includes a heating furnace 1, a cooling section 4 and a conveying roller 5, and is characterized in that an isolation baffle assembly is provided between the cooling section 4 and the heating furnace 1, and the isolation baffle assembly, the cooling section 4, the heating furnace 1 and the ground 6 together constitute a flow field space for stabilizing the airflow, the conveying roller 5 passes through the flow field space and the cooling section 4 by the heating furnace 1, and the isolation baffle assembly is composed of a windshield 3 and a sealing plate 2.

[0034] In this embodiment, one end of the wind shield 3 is fixed on one side of the cooling section 4, and the other end is provided with a fixing hole for fixing the sealing plate 2. One end of the sealing plate 2 is connected to the wind shield 3 through the fixing hole, and the other end is in contact with the heating furnace 1 to form a flow field space.

[0035] Further, the sealing plate 2 is also made of soft material resistant to high temperature, such as ceramic glass cloth, which can effectively block the airflow and will not affect the lifting action of the heating furnace 1 and the air box 8.

[0036] When the upper and lower air boxes 8 of the cooling section 4 start blowing, the airflow blown downward by the upper air box 8 forms a specific airflow flow field interval below the conveying roller 5 under the blockage of the ground 6; the airflow blown upward by the lower air box 8 also forms a specific airflow flow field interval above the conveying roller 5 under the blockage of the wind shield 3. In this way, when the glass 7 enters the cooling section 4 from the heating furnace 1 under the action of the conveying roller 5, the upper and lower surfaces of the glass 7 are in a substantially close airflow environment, which helps to achieve temperature balance control of the upper and lower surfaces of the glass 7, thereby improving the flatness and quality of the glass.

[0037] Example Three,

[0038] An airflow stabilizing device for cooling tempered glass, comprising a heating furnace 1, a cooling section 4 and a conveying roller 5, characterized in that an isolation baffle assembly is arranged between the cooling section 4 and the heating furnace 1, the isolation baffle assembly, together with the cooling section 4, the heating furnace and the ground 61, forms a flow field space for stabilizing airflow, the conveying roller 5 passes through the flow field space from the heating furnace 1 to the cooling section 4, and the isolation baffle assembly is composed of a wind shield 3 and a sealing plate 2.

[0039] In this embodiment, the wind shield 3 is fixed at one side of the heating furnace 1, and the other end is provided with a fixing hole for fixing the sealing plate 2. One end of the sealing plate 2 is connected with the wind shield 3 through the fixing hole, and the other end is in contact with the cooling section 4 to form the flow field space.

[0040] The sealing plate 2 is made of soft material resistant to high temperature, such as ceramic glass cloth, which can effectively block the airflow and will not affect the lifting action of the cooling section 4.

[0041] In this embodiment, the isolation baffle assembly is further provided with a flow guide structure at the connection with the cooling section 4 for guiding the turbulent airflow of the cooling section 4 out.

[0042] When the upper and lower air boxes 8 of the cooling section 4 start blowing, the airflow blown downward by the upper air box 8 forms a specific airflow flow field interval below the conveying roller 5 under the blockage of the ground 6; the airflow blown upward by the lower air box 8 also forms a specific airflow flow field interval above the conveying roller 5 under the blockage of the wind shield 3. In this way, when the glass 7 enters the cooling section 4 from the heating furnace 1 under the action of the conveying roller 5, the upper and lower surfaces of the glass 7 are in a substantially close airflow environment, which helps to achieve temperature balance control of the upper and lower surfaces of the glass 7, thereby improving the flatness and quality of the glass.
