Description

Technical Field

[0001] This utility model belongs to the field of glass tempering technology, specifically relating to a segmented glass tempering cooling device. Background Technology

[0002] Glass tempering cooling equipment typically employs a large air supply unit connected to an air collection box. The air collection box has two rows of air outlets, each connected to an upper or lower air grille. The large air supply unit's power must meet the air supply requirements of the entire system, resulting in extremely high noise levels during operation. This necessitates the construction of a separate soundproof room to house the large air supply unit, and controlling the air pressure for glass with varying tempering requirements is inconvenient. Furthermore, the large air supply unit has a long start-up cycle, and the entire air grille section can only be opened and closed simultaneously, resulting in wasted airflow in areas without glass, and ultimately, high energy consumption.

[0003] Existing technology CN204529655U mentions that to facilitate the control of each flat air grating, a variable frequency axial flow air supply unit can be directly installed at the end of each flat air grating. No air box or duct assembly for drive air blowing is installed between the air supply unit and the flat air grating. The air from the air supply unit enters the interior of the flat air grating, and the air pressure of each flat air grating can be controlled, with good pressure equalization, improving the uniformity of the final quenching air pressure. However, this technology uses many air supply units, resulting in high equipment costs. Furthermore, because the air supply units are directly installed at the ends of the flat air grating, their size and power are relatively small, which cannot meet the requirements for higher air pressure. Utility Model Content

[0004] The purpose of this invention is to provide a segmented glass tempering cooling device that uses multiple air supply units instead of a large air supply unit, so that each air supply unit can be precisely controlled, improving the glass tempering cooling effect, enabling the air supply units to start up quickly, and significantly reducing equipment energy consumption and operating noise.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a segmented glass tempering and cooling device, comprising multiple air grating groups and a glass conveying mechanism. Each air grating group includes multiple air grating units, and the air inlet of each air grating group is connected to the air inlets of the corresponding multiple air grating units. The multiple air grating groups include multiple upper air grating groups and multiple lower air grating groups. The glass conveying mechanism is used to convey glass between the multiple upper air grating groups and the multiple lower air grating groups. It also includes multiple air supply units, at least one of which is a shared air supply unit. The air inlet of at least one upper air grating group and the air inlet of at least one corresponding lower air grating group are both connected to the same shared air supply unit.

[0006] Furthermore, the number of wind grating units contained in each upper wind grating group is equal to the number of wind grating units contained in the corresponding lower wind grating group.

[0007] Furthermore, all of the aforementioned air supply units are the shared air supply unit.

[0008] Furthermore, if the rated power of the shared air supply unit is set to P, then 10KW≤P≤110KW.

[0009] Furthermore, 25KW≤P≤55KW.

[0010] Furthermore, the number of upper air gratings connected to each of the shared air supply units is equal to the number of lower air gratings.

[0011] Furthermore, the number of grating units in each grating group connected to the shared air supply unit is less than the number of grating units in the upper or lower grating group connected to the single-use air supply unit.

[0012] Furthermore, at least one of the multiple air supply units is a single-use air supply unit, which is connected to the air inlet of one of the upper air grating groups or the air inlet of one of the lower air grating groups.

[0013] Furthermore, an air collection box is also provided between the shared air supply unit and the upper and lower air grating groups connected thereto.

[0014] The beneficial effects of this utility model are: 1. By using multiple air supply units instead of a large air supply unit, each air supply unit can be precisely controlled, improving the cooling effect of glass tempering, enabling the air supply unit to start up quickly, and significantly reducing equipment energy consumption and operating noise.

[0015] 2. By using a shared air supply unit, the number of air supply units used is reduced, thus lowering equipment costs.

[0016] 3. The air grid assembly is segmented along the glass conveying direction to realize segmented air supply to the cooling equipment, accurately divide the blowing area, and significantly reduce equipment energy consumption. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0027] Example 1: As Figure 1-5 As shown, a segmented glass tempering and cooling device includes multiple air grating groups 100, multiple air supply units, and a glass conveying mechanism 200.

[0028] Each of the aforementioned air grating groups 100 includes multiple air grating units 104. Each air grating unit 104 has multiple air outlets on its side facing the glass conveying mechanism 200, and one end of the air grating unit 104 has an air grating unit inlet 105. The air grating unit inlets 105 of the multiple air grating units 104 in the same air grating group 100 are all connected to the air grating group inlet 103 of the air grating group 100, and air is simultaneously supplied to the multiple air grating units 104 in the air grating group 100 through the air grating group inlet 103. The multiple air grating groups 100 are divided into multiple upper air grating groups 101 and multiple lower air grating groups 102. The multiple upper air grating groups 101 are located above the glass conveying mechanism 200, and the multiple lower air grating groups 102 are located below the glass conveying mechanism 200. The upper air grating groups 101 and lower air grating groups 102 are arranged vertically correspondingly. The glass conveying mechanism 200 conveys glass between multiple upper air grate groups 101 and multiple lower air grate groups 102. The glass conveying mechanism 200 can be a roller conveyor or other conveying mechanism commonly used in the glass processing industry; the specific structure will not be described in detail. The air supply unit is a commonly used air supply component such as a fan, air compressor, or air pump; this embodiment uses a centrifugal fan as an example.

[0029] like Figure 1 As shown, one of the air supply units is a shared air supply unit 300, and the rest are single-use air supply units 400. The shared air supply unit 300 is located at the inlet end of the glass tempering cooling equipment. The air inlet 103 of an upper air grating group 101 and the air inlet 103 of a lower air grating group 102 corresponding to the upper air grating group 101 are both connected to the shared air supply unit 300, allowing the shared air supply unit 300 to simultaneously supply air to both the connected upper air grating group 101 and lower air grating group 102. Figure 4 As shown. To enable the shared air supply unit 300 to simultaneously supply air to both the upper air grating group 101 and the lower air grating group 102, this embodiment employs a branch duct 600. The air inlet of the branch duct 600 is connected to the shared air supply unit 300, and the two air outlets of the branch duct 600 are connected to the upper air grating group 101 and the lower air grating group 102, respectively. In other embodiments, such as... Figure 5 As shown, a collection box 700 with two air outlets 701 can also be used to replace the branch duct 600 to connect the common air supply unit 300 and the upper and lower air grating groups. The structure of the collection box 700 can adopt a commonly used collection box structure, which will not be described in detail here. In addition to distributing the air pressure more reasonably to the multiple air grating groups 100, the collection box 700 can also prevent the hot air after cooling the hot glass from spreading to the common air supply unit 300.

[0030] The “glass tempering and cooling equipment inlet” mentioned above refers to the end where the glass enters the air grid group after it comes out of the heating furnace and is conveyed by the glass conveying mechanism 200.

[0031] like Figure 1 , 3 As shown, each of the single-use air supply units 400 is connected to the air inlet 103 of a corresponding upper air grating group 101 or a lower air grating group 102 through a single air duct 500, that is, it supplies air to the connected upper air grating group 101 or lower air grating group 102 one-to-one.

[0032] The shared air supply unit 300 and multiple individual air supply units 400 are all located on the same side of the glass conveying direction, with the shared air supply unit 300 located at the front end of the individual air supply units 400. The individual air supply unit 400 connected to the upper air grating group 101 is located above the individual air supply unit 400 connected to the lower air grating group 102, and in the vertical glass conveying direction, the individual air supply unit 400 connected to the upper air grating group 101 is closer to the air grating group 100 than the individual air supply unit 400 connected to the lower air grating group 102.

[0033] This embodiment takes the connection between the upper air grille group 101 and the lower air grille group 102 at the inlet end of the glass tempering cooling equipment and the common air supply unit 300 as an example. It does not limit the connection to the common air supply unit 300 to the upper air grille group 101 and the lower air grille group 102 at the inlet end of the glass tempering cooling equipment.

[0034] Preferably, the number of air grating units 104 in the upper air grating group 101 and lower air grating group 102 connected to the same shared air supply unit 300 is the same, and the same number of air grating units 104 are provided in both the upper air grating group 101 and lower air grating group 102 connected to the single-use air supply unit 400. Furthermore, the number of air grating units 104 in each air grating group 100 connected to the shared air supply unit 300 is less than the number of air grating units 104 in the air grating group 100 connected to the single-use air supply unit 400, and the total number of air grating units 104 in multiple air grating groups 100 connected to a shared air supply unit 300 is greater than the number of air grating units 104 in the air grating group 100 connected to the single-use air supply unit 400. This allows different air supply units to better correspond to the air grating groups 100 they are connected to, making the number of air grating units 104 within each air grating group 100 more rationally configured.

[0035] In this embodiment, both the upper air grating group 101 and the lower air grating group 102, which are connected to the shared air supply unit 300, include four air grating units 104, so these two air grating groups 100 have a total of eight air grating units 104. The upper air grating group 101 or the lower air grating group 102, which are connected to the single-use air supply unit 400, each has six air grating units 104.

[0036] It should be noted that the number of air grating units 104 in all air grating groups 100 in this invention can be selected according to actual conditions. In another embodiment, all air grating groups 100 contain the same number of air grating units 104. The number of air grating units 104 in multiple air grating groups 100 connected to the shared air supply unit 300 differs from the number of air grating units 104 in air grating groups 100 connected to a single air supply unit 400, in order to better distribute air supply pressure and blowing area, which is a preferred solution. Those skilled in the art will understand from this embodiment that even with all air grating groups 100 containing the same number of air grating units 104, and with a reasonable selection of air supply units, good air pressure distribution and blowing area control can still be achieved.

[0037] This embodiment uses multiple air supply units instead of the large air supply unit in the prior art, and the number of air grid units 104 included in each upper air grid group 101 is the same as the number of air grid units 104 included in the corresponding lower air grid group 102 above and below it. This allows each air supply unit to be precisely controlled, improving the cooling effect of glass tempering, enabling rapid start-up of the air supply units, and significantly reducing equipment energy consumption and operating noise. Using a shared air supply unit 300 can further reduce the number of air supply units used, reducing equipment costs. In the glass conveying direction, the cooling equipment is segmented by the arrangement of air supply units and air grid groups 100, realizing segmented independent air supply to the air grids, accurately dividing the blowing area, enriching the air pressure control methods, improving equipment control accuracy, and significantly reducing equipment energy consumption. For example, when the glass first enters the cooling equipment, the first section of the air duct blows out high-pressure air to rapidly cool the glass. The air pressure of each subsequent section is lower than that of the first section of the air duct, which can ensure the cooling efficiency of the glass and reduce the energy consumption of the equipment. Alternatively, only the air supply of the air ducts in the area where the glass is located can be turned on, while the air supply of the air ducts in the areas away from the glass can be turned off to reduce the energy consumption of the equipment.

[0038] The rated power of the shared air supply unit 300 is set within the range of 10kW to 110kW, particularly within the range of 25kW to 55kW; the rated power of the single air supply unit 400 is greater than or equal to 10kW and less than or equal to 100kW. By setting the power of the air supply units, not only can wind pressure, noise, and energy consumption be better considered, but the cooling wind pressure and cooling rate requirements at different stages after the glass enters the cooling equipment can also be met. In this embodiment, the rated power of the shared air supply unit 300 is 40kW, and the rated power of the single air supply unit 400 is 30kW.

[0039] In other embodiments of this example, the shared air supply unit 300 can be connected to two upper air grating groups 101 and two lower air grating groups 102 that correspond vertically to the two upper air grating groups 101. The number of air grating groups 100 connected to the shared air supply unit 300 can be set as needed, as long as the upper and lower air grating groups correspond.

[0040] In another implementation, two or more shared air supply units 300 can be set up, which can further reduce the number of air supply units used and reduce equipment costs.

[0041] In another implementation, when multiple shared air supply units 300 and single air supply units 400 are provided, the rated power of each shared air supply unit 300 does not need to be consistent, nor does the rated power of each single air supply unit 400 need to be consistent; they can be set according to actual needs.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that a separate air supply unit 400 is no longer provided, such as... Figure 6 , 7 As shown, all air supply units are shared air supply units 300. All shared air supply units 300 are located on one side of the glass conveying direction. The number of upper air grating groups 101 connected to each shared air supply unit 300 is equal to the number of lower air grating groups 102 connected to it, and the number of air grating units 104 contained in all air grating groups 100 is equal.

[0044] All air supply units share a common air supply unit 300, which can further reduce the number of air supply units and reduce equipment costs. The number of upper and lower air grating groups is the same, and the number of air grating units 104 within the air grating group 100 is the same, which can reduce equipment production costs. At the same time, it makes the division of the air blowing area clearer and simplifies the equipment control logic.

[0045] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
