Description

Technical Field

[0001] The utility model relates to the technical field of electronic glass production, in particular to a blowing device for a blowing box body used in an electronic glass forming furnace. Background Art

[0002] The blowing box is an important component of electronic glass forming equipment. Its main function is to ensure that the temperature of the liquid glass coated on the surface of the overflow brick is consistent and slowly drops. The SIC box is a passive heat-saturating device. Its temperature source is the temperature of the liquid glass and the temperature of the heater below. Since the operating temperature requirement is lower than that of the liquid glass, the box needs to be cooled by blowing air.

[0003] The existing blowing device uses a single blowing pipe that constantly blows air into the box, and the pipe is located within the same cavity. In production practice, the temperature of the blowing box can only be adjusted in five locations: the center, the left and right sides of the center, and the sides. When faced with product quality issues, the temperature can only be adjusted in these general areas. Due to the need for more precise control of the box temperature, a blowing device with precise positioning is needed to achieve more accurate control of the box temperature. Utility Model Content

[0004] The purpose of the present utility model is to provide a blowing device for a blowing box for an electronic glass forming furnace to overcome the problems existing in the prior art. The present utility model can realize precise segmented control along the entire length direction of the blowing box, effectively control and optimize the temperature distribution in each area, ensure that the temperature of the glass is uniform at high temperatures, reduce stress concentration or deformation caused by uneven temperature, and even safety accidents, thereby improving the yield and quality of the product.

[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:

[0006] A blowing device for a blowing box of an electronic glass forming furnace, comprising a blowing device body mounted on a heat soaking box, a plurality of partition baffles fixed to one side of the blowing device body, the partition baffles dividing the blowing device body into a plurality of blowing cavities, each blowing cavity being connected to an external blowing pipe, and each blowing cavity being provided with an air inlet and an air outlet;

[0007] The spacing between the plurality of adjacent spacer baffles is the same;

[0008] Each blowing cavity is provided with an air inlet;

[0009] The external blowing pipe passes through the air inlet;

[0010] The external blowing pipe is threadedly connected to the blowing device body;

[0011] Each blowing cavity is provided with two exhaust ports;

[0012] The two air outlets are respectively arranged at the top and bottom of the blowing cavity;

[0013] The air inlet is a circular hole, and the air outlet is a semicircular hole;

[0014] The air inlet and the air outlet have the same radius;

[0015] The distance between the bottom of the spacer baffle and the heat equalizing box is ≤0.1 mm.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The utility model provides a blowing device for a blowing box body of an electronic glass forming furnace. The blowing device body is divided into a plurality of blowing cavities by arranging a plurality of spacer baffles. Each blowing cavity is relatively isolated from each other and interferes with each other less, thereby realizing precise segmented control over the entire length direction of the blowing box body; independently delivering cooling air through the air inlet and the air outlet can effectively control and optimize the temperature distribution of each area, ensure that the temperature of the glass is uniform at high temperature, reduce stress concentration or deformation caused by uneven temperature, and even reduce safety accidents, thereby improving the yield and quality of the product.

[0018] Furthermore, the spacing baffles with the same spacing can ensure uniform air intake and exhaust of each blowing cavity, which helps to evenly transfer the airflow on the glass surface and improve the heat dissipation efficiency.

[0019] Furthermore, each blowing cavity is provided with an independent air inlet, which helps to reduce the mutual interference of airflow between cavities and ensures that the airflow distribution in each cavity is more uniform and stable.

[0020] Furthermore, the external blowing pipe is connected to the blowing device body by a threaded connection. This connection method is not only firm and reliable, but also convenient for controlling the position of the blowing pipe.

[0021] Furthermore, each blowing cavity is provided with an exhaust port, which further prevents the cross-flow of cooling air from controlling the temperature of adjacent cavities; by setting the top and bottom exhaust ports to exhaust air simultaneously, the heat dissipation efficiency can be significantly improved, providing a more stable thermal environment for electronic glass forming.

[0022] Furthermore, the circular air inlet helps to reduce the eddy currents and turbulence of the air flow when it enters the blowing cavity, allowing the air flow to enter the cavity more smoothly; while the semicircular air outlet can change the outlet direction of the air flow while maintaining a certain blowing volume, making the air flow more dispersed and uniform when discharged, which is conducive to forming a more stable airflow field; the design of the semicircular air outlet can increase the diffusion area of ​​the air flow and improve the heat dissipation efficiency.

[0023] Furthermore, the bottom of the spacer baffle is in close contact with the heat equalization box, which can reduce interference with adjacent cavities, increase adjustment accuracy, and enhance anti-interference capability. BRIEF DESCRIPTION OF THE DRAWINGS
