Description

Technical Field

[0001] This utility model belongs to the field of glass tempering, specifically relating to a cooling mechanism with irregular front and rear air outlets. Background Technology

[0002] A glass tempering furnace typically includes a loading platform, a heating furnace, a tempering and cooling section, and a unloading platform. The glass is heated to a high temperature in the heating furnace, and then tempered and cooled in the tempering and cooling section. Cooling is achieved by blowing air onto the top and bottom of the glass using a fan in conjunction with an air duct with exhaust vents. The air duct generally consists of a bellows and several duct strips. Air is drawn into the bellows and then distributed to the individual duct strips, which have multiple regularly arranged exhaust vents through which air is blown onto the glass. For example, a Chinese patent discloses a wind-grate cooling mechanism, application number: 201420024038.8, which includes a first cooling mechanism and a second cooling mechanism. Both the first and second cooling mechanisms include a conveyor roller conveyor, and several wind grates are arranged along the conveyor roller conveyor above and below the conveyor roller conveyor. The conveyor roller conveyor in the first cooling mechanism is a unidirectional conveying through roller conveyor, and the wind grates on the upper and lower sides of the through roller conveyor are provided with linear continuous air outlets that can form a linear continuous air receiving surface on the glass surface. The conveyor roller conveyor in the second cooling mechanism is a swing roller conveyor that swings back and forth, and the wind grates on the upper and lower sides of the swing roller conveyor are provided with round hole-shaped air outlets.

[0003] The first cooling mechanism mentioned above is used in a unidirectional conveyor roller conveyor and employs a linear, continuous air outlet. The second cooling mechanism is used in a swing-type roller conveyor and employs a round-hole air outlet, thereby achieving segmented airflow between the tempering and cooling sections in the enhanced cooling section. However, in practical use, the linear, continuous air outlet of the aforementioned air grid cooling mechanism affects the flatness of the glass, easily resulting in bow-shaped glass, so it has not been adopted in practice. Meanwhile, the round-hole air outlets in the reciprocating section have a uniform and regular arrangement and airflow path. Although the air outlets are staggered to create a larger blowing surface, the overly regular airflow path still creates blind spots, resulting in uneven airflow onto the glass and the formation of wind spots. Therefore, the air grids used in existing glass tempering furnaces need improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a wind grid structure that can be applied to the cooling section of a glass tempering furnace, and in particular, a wind grid cooling mechanism with irregular front and rear air outlets to reduce wind spots.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A cooling mechanism with irregular front and rear air outlets includes several air packs, each consisting of an air box and several air grid strips. The side of the air grid strips facing the glass has an air outlet surface, and an air outlet unit is provided on the air outlet surface. The air outlet unit is characterized in that it is formed by a combination of dot-shaped air outlet holes, and the cooling mechanism has at least three different combinations of air outlet units.

[0007] Furthermore, the air outlet unit is composed of parallel sets of oblique air outlet holes, which are composed of multiple air outlet holes arranged coaxially in a certain direction.

[0008] Furthermore, the air grille cooling mechanism has at least two groups of oblique air outlets arranged in different axial directions.

[0009] Furthermore, the diameter of the air outlets in the inclined air outlet group gradually increases or decreases along the axial direction.

[0010] Furthermore, the air outlet unit is composed of square holes arranged horizontally at intervals.

[0011] Furthermore, the adjacent square holes are staggered vertically.

[0012] Furthermore, for air outlet units of the same shape, the distance between them and the edge of the air outlet surface varies on different air outlet surfaces.

[0013] Furthermore, the shapes of the air outlet units on adjacent air outlet surfaces are different.

[0014] Furthermore, each air vent includes two air outlets on the side facing the glass, which are arranged in a V-shape.

[0015] Compared with the prior art, this utility model provides a new air outlet method. Compared with the traditional single regular air outlet layout, this air grid cooling mechanism is provided with at least three different shapes of air outlet units, which are arranged in a cross pattern. This can compensate for the actual air outlet area and eliminate the air outlet dead corners, thus effectively reducing wind spots. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-4 As shown, this embodiment provides a cooling mechanism with irregular front and rear air outlets, including several air chambers. Each air chamber consists of an air box 1 and several air grille strips 2. The side of the air grille strips 2 facing the glass has an air outlet surface 3, and the air outlet surface 3 is provided with air outlet units 4. The air outlet units 4 are formed by a combination of dot-shaped air outlet holes. This cooling mechanism has at least three different combinations of air outlet units 4. The shapes of the air outlet units on adjacent front and rear air outlet surfaces are not the same. Each air grille strip includes two air outlet surfaces with a V-shaped angle on the side facing the glass.

[0022] This embodiment provides three types of air outlet units 4 with different shapes: a first air outlet unit 41, a second air outlet unit 42, and a third air outlet unit 43. The first air outlet unit 41 and the second air outlet unit 42 are both composed of parallel sets of oblique air outlet holes. Each set of oblique air outlet holes consists of multiple air outlet holes arranged coaxially in a certain direction. In this embodiment, the first air outlet unit 41 has three circular air outlet holes arranged obliquely upwards, and the diameters of the holes in the second air outlet unit 42 from left to right are 4.3mm, 4.4mm, and 4.5mm, respectively. The second air outlet unit 42 has three air outlet holes arranged obliquely downwards, and the diameters of the holes from right to right are 4.31mm, 4.41mm, and 4.51mm, respectively. In this embodiment, the air vent has two air outlet surfaces, which are V-shaped. The air outlet surfaces are inclined. The diameter of the air outlet near the center line of the air vent should be the smallest, and the diameter of the air outlet further away from the center line of the air vent should be larger. Thus, the farther away from the glass, the larger the air outlet needs to be to ensure a larger air volume, so that the air pressure blown towards the glass from each air outlet is uniform.

[0023] In actual manufacturing, the first air outlet unit 41 and the second air outlet unit 42 can be composed of inclined air outlet hole groups with other slopes, or more inclined air outlet hole groups with different slopes can be set to make the air outlet more diffuse and irregular.

[0024] The third air outlet unit 43 in this embodiment is composed of square holes arranged horizontally at intervals, with adjacent square holes staggered vertically. The square holes are larger than the air outlet holes of the first air outlet unit 41 and the second air outlet unit 42, thus having different air outlet ranges.

[0025] To achieve a more staggered and irregular airflow from each air outlet unit, in this embodiment, air outlet units of the same shape are spaced at different distances from the edge of the air outlet surface on different outlet surfaces. For example... Figure 3 , 4As shown, the distances of the two first air outlet units 41 from the edge of the air outlet surface on their respective wind grating surfaces are D1 and D2, the distances of the two second air outlet units 42 from the edge of the air outlet surface on their respective wind grating surfaces are D3 and D4, and the distances of the two third air outlet units 43 from the edge of the air outlet surface on their respective wind grating surfaces are D5 and D6. Figure 4 The third air outlet unit 43 is arranged on both of the two air grating strips 2. D5 and D6 only select the distance between the third air outlet unit 43 on two of the air outlet surfaces and the edge. D1 and D2 are different, D3 and D4 are different, D5 and D6 are different. Furthermore, D1, D2, D3, D4, D5 and D6 can all be different so that the air outlet range at the edge of the air outlet surface is not completely the same.

[0026] To achieve a staggered arrangement, the air outlet units near the edge of the air outlet surface may not be complete.

[0027] The air outlet units of the air grating cooling mechanism provided in this embodiment compensate each other in terms of air outlet direction and air outlet range, which can cover the glass to the maximum extent, increase the glass air-receiving area, and prevent the glass from having dead corners for air outlet and air-receiving, thus effectively reducing wind spots.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
