Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering equipment, in particular to a flat air grid quenching system for a passing section. Background Art

[0002] The tempering wind pressure of glass tempering is one of the most important process parameters, and it has a direct impact on the tempering degree and tempering effect of glass.

[0003] The existing technology adjusts the tempered wind pressure by controlling the position of the guide plate located at the center of the wind collecting box to adjust the wind pressure of the upper wind grid and the wind pressure of the lower wind grid. Adjusting it upward can increase the wind pressure of the upper wind grid and reduce the wind pressure of the lower wind grid; while adjusting it downward can increase the pressure of the lower wind grid and reduce the wind pressure of the upper wind grid.

[0004] Although the guide plate can adjust the wind pressure of the upper wind grid and the lower wind grid, it cannot make the wind pressure of the upper wind grid and the lower wind grid infinitely close. As a result, the tempering wind pressure acting on the two sides of the tempered glass is too different, which will also cause ripples on the glass surface and affect the quality of glass tempering. Utility Model Content

[0005] In view of the above-mentioned shortcomings, the purpose of the utility model is to propose a flat air grille quenching system for a through section, which does not use a guide plate, adopts two fans, and outputs quenching air with the same wind pressure to the upper air grille and the lower air grille through two air ducts, so as to reduce the wave patterns on the glass surface.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A flat air grid quenching system for a through section includes an air pressure control module, a first fan, a second fan, a flat air grid, a first air duct, and a second air duct;

[0008] The flat wind grille includes an upper wind grille and a lower wind grille;

[0009] The first fan is connected to the upper air grille through the first air duct, and the second fan is connected to the lower air grille through the second air duct;

[0010] The first fan and the second fan are respectively connected to the wind pressure control module signal; the wind pressure control module controls the output wind pressure of the first fan and the second fan respectively, and makes the wind pressure of the upper wind grid and the wind pressure of the lower wind grid the same.

[0011] Furthermore, the upper wind grille and the lower wind grille are both equipped with wind pressure detection components;

[0012] The two wind pressure detection components are respectively connected to the wind pressure control module signals.

[0013] Further, it also includes a static pressure bellows;

[0014] A partition extending in the horizontal direction is provided in the middle of the static pressure wind box; the partition divides the static pressure wind box into an upper static pressure wind box and a lower static pressure wind box;

[0015] The output end of the first air duct and the output end of the second air duct are connected to the input port of the upper static pressure wind box and the input port of the lower static pressure wind box respectively;

[0016] The upper air grille and the lower air grille are connected to the output port of the upper static pressure wind box and the output port of the lower static pressure wind box respectively.

[0017] Further, it includes canvas ducts;

[0018] Canvas air ducts are installed between the output end of the upper air grid and the output port of the upper static pressure wind box, and between the output end of the lower air grid and the output port of the lower static pressure wind box.

[0019] Furthermore, the output ends of the first air duct and the output ends of the second air duct are aligned vertically;

[0020] The static pressure wind box is located between the first fan and the second fan; the distance between the first fan and the static pressure wind box is different from the distance between the second fan and the static pressure wind box;

[0021] The angle between the central axis of the first air duct and the extended line of the central axis of the static pressure wind box is angle α, the angle between the central axis of the second air duct and the extended line of the central axis of the static pressure wind box is angle β, and the angle α is equal to the angle β.

[0022] The beneficial effects of the technical solution of the utility model are as follows: the flat air grid quenching system for passing through the segment forms a first air supply channel through the first fan and the first air duct, and a second air supply channel through the second fan and the second air duct, and then controls the output air pressures of the first fan and the second fan respectively through the air pressure control module, so that the two sides of the to-be-tempered glass between the upper air grid and the lower air grid obtain quenching air with an air pressure infinitely close to that equivalent to the same air pressure, thereby minimizing the wave pattern on the glass surface and further improving the quality of glass tempering.

[0029] A flat air grid quenching system for a through section, comprising an air pressure control module, a first fan 1, a second fan 2, a flat air grid 3, a first air duct 11 and a second air duct 12;

[0030] The flat air grille 3 includes an upper air grille 31 and a lower air grille 32;

[0031] The first fan 1 is connected to the upper air grille 31 through the first air duct 11, and the second fan 2 is connected to the lower air grille 32 through the second air duct 12;

[0032] The first fan 1 and the second fan 2 are respectively connected to the wind pressure control module signal; the wind pressure control module controls the output wind pressure of the first fan 1 and the second fan 2 respectively, and makes the wind pressure of the upper wind grid 31 and the wind pressure of the lower wind grid 32 the same.

[0033] like Figure 1-2As shown, the flat air grid quenching system for passing through the section of the utility model, the first fan 1 and the first air duct 11 form a first air supply channel and output upper quenching air to the upper air grid 31, the second fan 2 and the second air duct 12 form a second air supply channel and output lower quenching air to the lower air grid 32, and the output air pressures of the first fan 1 and the second fan 2 are respectively controlled by the air pressure control module, so that the two sides of the to-be-tempered glass between the upper air grid 31 and the lower air grid 32 obtain quenching air with air pressures infinitely close to each other, that is, quenching air with the same air pressure.

[0034] Furthermore, the upper air grille 31 and the lower air grille 32 are both installed with a wind pressure detection member 311;

[0035] The two wind pressure detection components 311 are respectively connected to the wind pressure control module signals.

[0036] like Figure 1 As shown, the wind pressure control module obtains the instantaneous wind pressure of the upper wind grid 31 and the lower wind grid 32 respectively through two wind pressure detection components 311, so as to adjust the output wind pressure of the first fan 1 and the second fan 2 accordingly, so that the wind pressure of the upper wind grid 31 and the wind pressure of the lower wind grid 32 are infinitely close.

[0037] Further, it also includes a static pressure wind box 4;

[0038] A partition plate 41 extending in the horizontal direction is provided in the middle of the static pressure wind box 4; the partition plate 41 divides the static pressure wind box 4 into an upper static pressure wind box 42 and a lower static pressure wind box 43;

[0039] The output end of the first air duct 11 and the output end of the second air duct 12 are connected to the input port of the upper static pressure wind box 42 and the input port of the lower static pressure wind box 43 respectively;

[0040] The upper air grille 31 and the lower air grille 32 are connected to the output port of the upper static pressure wind box 42 and the output port of the lower static pressure wind box 43 respectively.

[0041] like Figure 1 As shown, the upper static pressure bellows 42 and the lower static pressure bellows 43 are configured to reduce the dynamic pressure of the first air duct 11 and the second air duct 12 and increase the static pressure, thereby stabilizing the airflow and obtaining a more ideal air supply effect.

[0042] The upper static pressure bellows 42 and the lower static pressure bellows 43 can also fix the output end of the first air duct 11 and the output end of the second air duct 12 , thereby improving the installation stability of the first air duct 11 and the second air duct 12 .

[0043] Further, it also includes a canvas air duct 5;

[0044] A canvas air duct 5 is installed between the output end of the upper air grid 31 and the output port of the upper static pressure wind box 42 , and between the output end of the lower air grid 32 and the output port of the lower static pressure wind box 43 .

[0045] like Figure 1-2 As shown, a canvas air duct 5 is used to connect the output end of the upper air grid 31 and the output port of the upper static pressure bellows 42, or the output port of the lower air grid 32 and the lower static pressure bellows 43 in a flexible manner, which can reduce air flow vibration and reduce the installation accuracy of the flat air grid quenching system used for the passing section.

[0046] Furthermore, the output end of the first air duct 11 and the output end of the second air duct 12 are aligned vertically;

[0047] The static pressure wind box 4 is located between the first fan 1 and the second fan 2; the distance between the first fan 1 and the static pressure wind box 4 is different from the distance between the second fan 2 and the static pressure wind box 4;

[0048] The angle between the central axis of the first air duct 11 and the extended line of the central axis of the static pressure wind box 4 is angle α, and the angle between the central axis of the second air duct 12 and the extended line of the central axis of the static pressure wind box 4 is angle β, and the angle α is equal to the angle β.

[0049] like Figure 2 As shown, the distance between the first fan 1 and the static pressure wind box 4 is different from the distance between the second fan 2 and the static pressure wind box 4, which can avoid the resonance between the first fan 1 and the second fan 2 during operation; the first air duct 11 and the second air duct 12 are distributed at equal angles on both sides of the extension line of the line connecting the central axis of the static pressure wind box 4 and the central axis of the flat air grid 3, which can avoid the resonance between the first air duct 11 and the second air duct 12, and avoid the wind pressure difference caused by the different input angles of the first air duct 11 and the second air duct 12 relative to the static pressure wind box 4.

[0050] In summary, if Figure 1-2 In the embodiment of the utility model shown, the flat air grid quenching system for passing through the segment forms a first air supply channel through the first fan 1 and the first air duct 11, and a second air supply channel through the second fan 2 and the second air duct 12, and then controls the output air pressures of the first fan 1 and the second fan 2 respectively through the air pressure control module, so that the two sides of the to-be-tempered glass between the upper air grid 31 and the lower air grid 32 obtain quenching air with an air pressure infinitely close to that equivalent to the same air pressure, thereby minimizing the wave pattern on the glass surface and further improving the quality of glass tempering.
