Description

Technical Field

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

[0002] Glass tempering cooling equipment typically uses a large air supply unit connected to an air collection box. The air collection box has two rows of air outlets, one above the other. Each air outlet is connected to a set of upper or lower air grilles. The power of the large air supply unit must meet the air supply requirements of the entire equipment. It is extremely noisy during operation, requiring a separate soundproof room to house the large air supply unit. Furthermore, the air pressure control for glass with different tempering blowing requirements is not precise.

[0003] Existing technology also mentions that tempering cooling equipment is divided into high-pressure section and low-pressure section according to the air pressure of the blowing. Each high-pressure section and low-pressure section is equipped with an air supply unit to supply air. However, the air supply unit supplies air to all upper air grilles and all lower air grilles through an air collection box. But in the actual tempering blowing of flat glass, the blowing air pressure of the upper air grille is different from that of the lower air grille. Directly using an air supply unit cannot achieve independent and precise adjustment of the air pressure of the upper and lower air grilles.

[0004] 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

[0005] The purpose of this utility model is to provide a glass tempering cooling device that can achieve independent air supply to the upper and lower air grilles, and has the advantages of low equipment cost, low equipment energy consumption, and low equipment noise.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a 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 its 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 upper air supply units and multiple lower air supply units, the multiple upper air supply units being used to supply air to the multiple upper air grating groups, and the multiple lower air supply units being used to supply air to the multiple lower air grating groups.

[0007] At least one of the multiple upward air supply units is a shared upward air supply unit, which is connected to the air inlet of at least two upward air grating groups; and / or, at least one of the multiple downward air supply units is a shared downward air supply unit, which is connected to the air inlet of at least two downward air grating groups.

[0008] In one implementation, the plurality of upper air supply units are all common upper air supply units, and the plurality of lower air supply units are all common lower air supply units.

[0009] Furthermore, the number of upper air grating groups connected to each of the common upper air supply units is equal to the number of lower air grating groups connected to each of the common lower air supply units, and the number of air grating units contained in each upper air grating group is equal to the number of air grating units contained in each lower air grating group.

[0010] In one implementation, the rated power of the shared upper air supply unit and the shared lower air supply unit are equal. Let the rated power of the shared upper air supply unit and the shared lower air supply unit be P, then 10KW≤P≤110KW.

[0011] Furthermore, 25KW≤P≤55KW.

[0012] In one embodiment, an air collection box is further provided between the shared upper air supply unit and at least two upper air grating groups connected thereto, and an air collection box is further provided between the shared lower air supply unit and at least two lower air grating groups connected thereto.

[0013] In one implementation, at least one of the plurality of upper air supply units is a single-use upper air supply unit, which is connected to the air inlet of one of the upper air grating groups; at least one of the plurality of lower air supply units is a single-use lower air supply unit, which is connected to the air inlet of one of the lower air grating groups.

[0014] Furthermore, the air inlets of at least two of the upper air grating groups near the inlet end of the cooling equipment are connected to a common upper air supply unit, and the air inlets of at least two of the lower air grating groups near the inlet end of the cooling equipment are connected to a common lower air supply unit.

[0015] The beneficial effects of this utility model are: 1. In this cooling device, at least two upper air grating groups are supplied with air by at least one shared upper air supply unit, and / or at least two lower air grating groups are supplied with air by at least one shared lower air supply unit. This arrangement realizes independent air supply for the upper and lower air gratings, facilitates independent and precise adjustment of the air pressure of the upper and lower air gratings, and reduces the number of air supply units, thereby reducing costs.

[0016] 2. The air inlets of at least two upper air grid groups near the inlet of the cooling device are connected to a common upper air supply unit, and the air inlets of at least two lower air grid groups near the inlet of the cooling device are connected to a lower air supply unit. This can meet the high-pressure rapid cooling air pressure requirements when hot glass enters the cooling equipment after exiting the furnace, and improve the glass cooling and tempering effect.

[0017] 3. This utility model replaces the large air supply unit with multiple small air supply units, which can realize the rapid start-up of the air supply unit, reduce equipment noise, improve the noise environment of the factory, and eliminate the need for additional air supply unit rooms, further reducing costs.

[0018] 4. Both the shared air supply unit and the single air supply unit can be adjusted independently, achieving precise control of air pressure regulation and reducing equipment energy consumption. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Example 1: As Figure 1 , 2 As shown, a glass tempering and cooling device includes multiple air grating groups 100, a glass conveying mechanism 200, and an air supply unit.

[0029] Each air grating assembly 100 includes multiple air grating units 101. The air grating assembly inlet 103 of each air grating assembly 100 is connected to the air grating unit inlets 102 of the corresponding multiple air grating units 101. The air supply unit is connected to the air grating assembly inlet 103, and air is supplied to the multiple air grating units 101 in the air grating assembly 100 simultaneously through the air grating assembly inlet 103. The multiple air grating assemblies 100 include multiple upper air grating assemblies 104 and multiple lower air grating assemblies 105. The multiple upper air grating assemblies 104 are located above the glass conveying mechanism 200 and blow air onto the upper surface of the glass. The multiple lower air grating assemblies 105 are located below the glass conveying mechanism 200 and blow air onto the lower surface of the glass.

[0030] The glass conveying mechanism 200 is used to convey glass. It can be a commonly used roller conveyor or other conveying mechanism. The specific structure will not be described in detail.

[0031] like Figure 3 As shown, the air supply unit is divided into an upper air supply unit 300 and a lower air supply unit 400 according to the vertical division of the air grille group 100 above or below the glass conveying mechanism 200, respectively supplying air to the upper air grille group 104 and the lower air grille group 105. Multiple upper air supply units 300 are provided to supply air to multiple upper air grille groups 104, and multiple lower air supply units 400 are provided to supply air to multiple lower air grille groups 105. The air supply unit can be a commonly used component such as a fan, air compressor, or air pump; this embodiment uses a centrifugal fan as an example.

[0032] like Figure 2As shown, at least one of the multiple upper air supply units 300 is a shared upper air supply unit 301, and the rest are single-use upper air supply units 302. The shared upper air supply unit 301 is connected to the air inlet 103 of multiple adjacent upper air grating groups 104 to supply air to the multiple upper air grating groups 104, thereby reducing the number of upper air supply units 300. Each single-use upper air supply unit 302 is connected to the air inlet 103 of one upper air grating group 104 to supply air to that upper air grating group 104. At least one of the multiple lower air supply units 400 is a shared lower air supply unit 401, and the rest are single-use lower air supply units 402. The shared lower air supply unit 401 is connected to the air inlet 103 of multiple adjacent lower air grating groups 105 to supply air to the multiple lower air grating groups 105, thereby reducing the number of lower air supply units 400. Each single-use lower air supply unit 402 is connected to the air inlet 103 of a lower air grating group 105 for supplying air to the lower air grating group 105.

[0033] according to Figure 2 As shown, in this embodiment, there are six upper air duct groups 104 and six lower air duct groups 105. The upper air supply unit 300 includes one shared upper air supply unit 301 and four individual upper air supply units 302, and the lower air supply unit 400 includes one shared lower air supply unit 401 and four individual lower air supply units 402. The shared upper air supply unit 301 is connected to two upper air duct groups 104 at the side via an air duct, and the other four individual upper air supply units 302 are connected one-to-one with the other four upper air duct groups 104. The shared lower air supply unit 401 is connected to two lower air duct groups 105 at the side via an air duct, and the other four individual lower air supply units 402 are connected one-to-one with the other four lower air duct groups 105.

[0034] Furthermore, multiple upper air supply units 300 and multiple lower air supply units 400 are all located on the same side of the glass conveying direction, with the upper air supply units 300 positioned above the lower air supply units 400. This vertical arrangement allows the air supply units and the air grid assembly to be arranged vertically, which helps reduce the footprint of the air supply units, facilitates the overall layout of the connecting pipelines, ensures unobstructed air supply pipelines, and reduces air pressure loss. Moreover, in the vertical glass conveying direction, the upper air supply units 300 are closer to the air grid assembly 100 than the lower air supply units 400, which is beneficial for the arrangement of the air supply units and ensures the stability of the air supply units during operation.

[0035] In this embodiment, the upper air supply unit 300 and the lower air supply unit 400 are arranged vertically and vertically respectively. Correspondingly, the upper air grating group 104 and the lower air grating group 105 connected to the upper air supply unit 300 and the lower air supply unit 400 are also arranged vertically and vertically respectively. This makes the arrangement of the air supply unit and the air grating group simpler and more stable, and at the same time, the division of the air blowing area is clearer.

[0036] Furthermore, the rated power of the shared upper air supply unit 301 is greater than or equal to the rated power of the single upper air supply unit 302; the rated power of the shared lower air supply unit 401 is greater than or equal to the rated power of the single lower air supply unit 402.

[0037] Specifically, the rated power P of the shared upper air supply unit 301 is greater than or equal to 10 kW and less than or equal to 110 kW. More preferably, the rated power P of the shared upper air supply unit 301 is greater than or equal to 25 kW and less than or equal to 55 kW. In this embodiment, the rated power P of the shared upper air supply unit 301 is 40 kW. The rated power P of the shared lower air supply unit 401 is greater than or equal to 10 kW and less than or equal to 110 kW. More preferably, the rated power P of the shared lower air supply unit 401 is greater than or equal to 25 kW and less than or equal to 55 kW. In this embodiment, the rated power P of the shared lower air supply unit 401 is 40 kW.

[0038] The rated power P of the single-use upper air supply unit 302 and the single-use lower air supply unit 402 is greater than or equal to 10 kW and less than or equal to 100 kW. In this embodiment, the rated power P of the single-use upper air supply unit 302 and the single-use lower air supply unit 402 is 30 kW.

[0039] By optimizing the power design of the air supply unit, factors such as air pressure, noise, and energy consumption can be better considered to improve the cooling equipment.

[0040] Furthermore, higher air pressure is typically required when the glass first enters the cooling equipment for rapid cooling. Therefore, two or more upper air grating groups 104 and multiple lower air grating groups 105 near the inlet of the cooling equipment are respectively connected to a corresponding common air supply unit. In this embodiment, the two upper air grating groups 104 near the inlet of the cooling equipment are connected to a common upper air supply unit 301, and the two lower air grating groups 105 near the inlet of the cooling equipment are connected to a common lower air supply unit 401, to meet the high-pressure quenching air pressure requirements for rapid cooling of hot glass entering the cooling equipment. The inlet of the cooling equipment refers to the end where the glass enters the air grating group 100 after exiting the heating furnace and being conveyed by the glass conveying mechanism 200.

[0041] Furthermore, the number of air grating units 101 in each upper air grating group 104 connected to the shared upper air supply unit 301 is less than the number of air grating units 101 in the upper air grating group 104 connected to the single upper air supply unit 302. Similarly, the number of air grating units 101 in each lower air grating group 105 connected to the shared lower air supply unit 401 is less than the number of air grating units 101 in the lower air grating group 105 connected to the single lower air supply unit 402. Furthermore, the total number of air grating units 101 in all upper air grating groups 104 connected to the shared upper air supply unit 301 is greater than the number of air grating units 101 in the upper air grating group 104 connected to the single upper air supply unit 302. Similarly, the total number of air grating units 101 in all lower air grating groups 105 connected to the shared lower air supply unit 401 is greater than the number of air grating units 101 in the lower air grating group 105 connected to the single lower air supply unit 402.

[0042] The above method for setting the number of wind grating units 101 within the wind grating assembly 100 can be referenced. Figure 4 As shown, taking the upper air grating group 104 as an example, the common upper air supply unit 301 is connected to the air inlet of the two upper air grating groups 104 near the inlet end of the cooling equipment. Each upper air grating group 104 connected to the common upper air supply unit 301 contains 4 air grating units 101, and the two upper air grating groups 104 connected to the common upper air supply unit 301 contain a total of 8 air grating units 101. Each upper air grating group 104 connected to the single upper air supply unit 302 contains 6 air grating units 101.

[0043] In this embodiment, the upper air grille group 104 and the lower air grille group 105 are arranged vertically and vertically. Therefore, the common lower air supply unit 401 is connected to the air inlet of the two lower air grille groups 105 near the inlet end of the cooling equipment. Each lower air grille group 105 connected to the common lower air supply unit 401 contains 4 air grille units 101, and the two lower air grille groups 105 connected to the common lower air supply unit 401 contain a total of 8 air grille units 101. Each lower air grille group 105 connected to the single lower air supply unit 402 contains 6 air grille units 101.

[0044] It should be noted that the number of air grating units in all air grating groups in this invention can be selected according to actual conditions. For example... Figure 2 All the wind grating groups shown contain the same number of wind grating units. Figure 4 The number of louver units 101 in the multiple louver groups 100 connected to the shared air supply unit shown is different from the number of louver units 101 in the louver group 100 connected to the single-use air supply unit. Generally, it is assumed that... Figure 4The arrangement shown provides better allocation of air supply pressure and blowing area, and is the preferred solution. However, those skilled in the art will understand from this embodiment that, with a reasonable selection of air supply units, an arrangement where all air grating groups 100 contain the same number of air grating units 101 can also achieve good air pressure distribution and blowing area control. Furthermore, those skilled in the art will understand from this embodiment that the number of air grating units 101 within the air grating group 100 can be set as needed, and they do not necessarily have to be identical. Similarly, the rated power of shared air supply units and the rated power of individually used air supply units do not necessarily have to be identical; both can be set according to actual needs.

[0045] This invention employs an upper air supply unit 300 and a lower air supply unit 400 to supply air to the upper air grille group 104 and the lower air grille group 105 respectively, achieving independent air supply to the upper and lower air grille groups. The air pressure can be precisely adjusted by directly regulating the power of the air supply unit, allowing for suitable air pressure adjustments for cooling different types of glass, improving the cooling and tempering effect of the glass, especially the cooling effect on LOW-E glass. Using a single shared air supply unit to supply air to both air grille groups simultaneously reduces the number of air supply units and lowers the manufacturing cost of the cooling equipment. Using multiple air supply units refines the airflow area of ​​the air grille groups, reduces the start-up time of the air supply units, effectively reduces equipment energy consumption, and significantly reduces operating noise, eliminating the need for a separate soundproof room and further reducing costs.

[0046] In other embodiments of this example, both the shared upper air supply unit 301 and the shared lower air supply unit 401 can be connected to three or any number of air grating groups 100. An air collection box 500 is also provided between the shared upper air supply unit 301 and at least two connected upper air grating groups 104, and between the shared lower air supply unit 401 and at least two connected lower air grating groups 105. The air outlet 501 of the air collection box 500 is connected to the air inlet 103 of the upper air grating group 104 or the lower air grating group 105, and the air outlet 501 of the air collection box 500 corresponds one-to-one with the air grating group 100 to which the air collection box 500 is connected. Providing an air collection box 500 between the shared air supply unit and the air grating group 100 allows for a more even distribution of air pressure to the multiple air grating groups 100. The structure of the air collection box 500 can adopt a commonly used air collection box structure, which will not be described in detail here.

[0047] Preferably, the air collection box 500 connected to the common upper air supply unit 301 is located above the air collection box 500 connected to the common lower air supply unit 401. Stacking the air collection boxes 500 vertically allows for better alignment between the air collection boxes 500 and the common upper and lower air supply units 301 and 401, facilitating the arrangement of connecting pipes. Furthermore, the stacked air collection boxes 500 act as a windbreak, preventing hot air from returning to the air supply unit after cooling the hot glass.

[0048] In other embodiments of this example, two or more shared air supply units can be set up, which can further reduce the number of air supply units used and reduce equipment costs.

[0049] Example 2

[0050] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that a separate air supply unit is no longer set up. All upper air supply units 300 share an upper air supply unit 301, and all lower air supply units 400 share a lower air supply unit 401.

[0051] Preferably, the number of shared upper air supply units 301 and shared lower air supply units 401 is equal. The number of upper air grating groups 104 connected to each shared upper air supply unit 301 is equal to the number of lower air grating groups 105 connected to each shared lower air supply unit 401, and the number of upper air grating units 101 included in each upper air grating group 104 is equal to the number of lower air grating units 101 included in each lower air grating group 105. The shared upper air supply units 301 and shared lower air supply units 401 are arranged vertically correspondingly. Each air supply unit is connected to two air grating groups 100. Specifically, as shown... Figure 6 As shown, taking the upper air supply unit as an example, the upper air supply unit consists of three shared upper air supply units 301. Each shared upper air supply unit 301 is connected to two upper air grating groups 104, and each upper air grating group 104 includes four air grating units 101. For the lower air supply unit, Figure 6 Although not shown, it can be seen from the vertical correspondence between the upper and lower air supply units and the upper air grating group 104 and the lower air grating group 105 that the lower air supply unit consists of three shared lower air supply units 401. Each shared lower air supply unit 401 is connected to two lower air grating groups 105, and each lower air grating group 105 includes four air grating units 101.

[0052] All air supply units are shared air supply units, 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, the number of air grating units in the air grating group is the same, and the number of upper and lower air supply units 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.

[0053] 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.
