A circulating cooling toughened glass windscreen assembly

Abstract

This invention discloses a circulating cooling tempered glass air vent assembly, comprising an upper air vent assembly and a lower air vent assembly arranged opposite each other. The lower part of the upper air vent assembly has an upper air blade, and the upper part of the lower air vent assembly has a lower air blade. Both the upper and lower air vent assemblies have built-in cooling circulation pipes, and each assembly has a cooling circulation inlet pipe and a cooling circulation outlet pipe connected to the corresponding built-in cooling circulation pipe. Installing cooling circulation water pipes inside the air vent alters the temperature and humidity within the air vent without affecting airflow or reducing air pressure. The built-in circulation water pipes are located on the outside of the air vent cavity, effectively creating a heat insulation layer inside the air vent. Because the water in the circulation pipes is constantly flowing, the absorbed heat is carried away through water circulation. During heat exchange, temperature and humidity can be effectively reduced, thus effectively reducing energy consumption and cost.

Description

Technical Field

[0001] This invention relates to the field of tempered glass technology, and in particular to a circulating cooling tempered glass air vent assembly. Background Technology

[0002] During the tempering process, wind pressure, temperature, and humidity directly affect the glass tempering. In photovoltaic glass tempering, reducing the operating frequency of the high-pressure fan can effectively reduce energy consumption. The upper and lower air grates of the glass tempering furnace should be parallel to the ground. During tempering, after the upper and lower air grates are leveled, the distance between them needs to be adjusted by approximately 10 millimeters when the glass thickness changes. This ensures the tempering quality of the photovoltaic glass, reduces fan operating frequency, and lowers energy consumption during tempering.

[0003] In existing air grating devices, the glass temperature drops from about 600 degrees to about 200 degrees during glass tempering. The only way to transfer the temperature of the hot air to the air grating is to dissipate the heat to the outside through the continuous flow of hot air. However, since glass production is a continuous process, it is difficult to reduce the temperature of the air grating by dissipating the heat to the outside through the continuous flow of hot air. Similarly, it is also difficult to reduce the temperature and humidity of the air blown onto the glass surface.

[0004] To reduce the temperature and humidity of the air, one method is to install a condenser inside the ventilation duct. The refrigeration system cools the condenser, and the condenser cools the air passing through it. However, because the condenser has a large resistance to the airflow, the cooling effect is not obvious, and the equipment modification costs for the refrigeration system, condenser, and duct are high. For example, a tempered glass cooling fan grille disclosed in patent CN219546876U requires additional energy consumption from the refrigeration system, and its performance is not ideal. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a circulating cooling tempered glass air vent assembly that can effectively reduce temperature and humidity, and has low energy consumption, thereby effectively reducing operating costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The circulating cooling tempered glass air grille assembly includes an upper air grille assembly and a lower air grille assembly arranged opposite each other. The lower part of the upper air grille assembly is provided with an upper air blade, and the upper part of the lower air grille assembly is provided with a lower air blade. Both the upper and lower air grille assemblies are provided with built-in cooling circulation pipes. Both the upper and lower air grille assemblies are provided with cooling circulation water inlet pipes and cooling circulation water outlet pipes that are connected to the corresponding built-in cooling circulation pipes.

[0007] Further or preferred: Both the upper and lower air grille assemblies include a set of air grille units arranged side by side, and the built-in cooling circulation pipes of adjacent air grille units are connected by circulation pipe connecting pipes.

[0008] The upper air grid assembly has an air pressure balance plate between adjacent upper air blades to control air pressure and prevent deformation during glass tempering, and the lower air grid assembly has a glass conveying roller conveyor between adjacent lower air blades.

[0009] The group of air grating units share a set of cooling circulation inlet pipe and cooling circulation outlet pipe, which are connected to the corresponding cooling circulation inlet pipe and cooling circulation outlet pipe by setting an external cooling circulation pipe.

[0010] The upper air grille assembly includes an upper air grille connector and an upper air grille cavity. The upper air grille connector is located above the upper air grille cavity, and an upper air inlet pipe is provided on the upper air grille connector. The upper air grille cavity has a cavity structure that is smaller at the top and larger at the bottom. The lower air grille assembly includes a lower air grille connector and a lower air grille cavity. The lower air grille connector is located below the lower air grille cavity, and a lower air inlet pipe is provided on the lower air grille connector. The lower air grille cavity has a cavity structure that is smaller at the bottom and larger at the top, and an internal cooling circulation pipe is located within the corresponding cavity structure.

[0011] Each of the aforementioned air grid units is provided with a set of air knives arranged side by side, and each air knife is provided with an air grid liner plate, the air grid liner plate having a concave structure corresponding to the air inlet pipe position.

[0012] The cooling circulation inlet pipe and cooling circulation outlet pipe are both connected to the cooling circulation inlet pipe and cooling circulation outlet pipe of each air grille unit via connecting hoses.

[0013] Each air knife in the air grid unit is provided with a built-in cooling circulation pipe, and a group of built-in cooling circulation pipes in the air grid unit are connected in series.

[0014] The built-in cooling circulation pipe has a figure-eight structure, and the series connection is located near the inner wall of the cavity structure.

[0015] Compared with the prior art, the present invention has the following advantages: This circulating cooling tempered glass air grille assembly is rationally designed. Cooling circulating water pipes are installed inside the air grille to change the temperature and humidity inside the grille without affecting the airflow or reducing air pressure. The built-in circulating water pipes are arranged on the outside of the air grille cavity, which is equivalent to adding a heat insulation layer inside the air grille. Because the water in the circulating water pipes is circulating, the absorbed heat is carried away through water circulation. During the heat exchange process, the temperature and humidity can be effectively reduced. The circulated hot water can be used in the glass washing machine. After passing through the water treatment system, the water can be recycled, reducing power consumption and saving energy. Attached Figure Description

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0030] Although the invention has been shown and described herein with reference to specific embodiments, it is not intended to be limited to the details shown. Rather, various modifications in detail may be made within the equivalent scope and scope of the claims without departing from the invention. In the drawings, the same item numbers refer to the same elements.

[0031] Throughout this disclosure, various terms are used to describe the physical shape or arrangement of features. Many of these terms are used to describe features conforming to a cylindrical or generally cylindrical geometry with the feature as its radius and a central axis perpendicular to that radius. Unless otherwise specified, the terms are given the following meanings: The terms “longitudinal,” “longitudinal,” “axial,” and “axial” refer to a direction, dimension, or orientation parallel to the central axis. The terms “radial” and “radially” refer to a direction, dimension, or orientation perpendicular to the central axis. The terms “inward” and “inner” refer to a direction, dimension, or orientation extending radially toward the central axis. The terms “outward” and “outer” refer to a direction, dimension, or orientation extending radially away from the central axis.

[0032] In this specification, relative terms such as “horizontal,” “vertical,” “upward,” “downward,” “top,” and “bottom,” and their derivatives (e.g., “horizontal,” “downward,” “upward,” etc.) should be interpreted as referring to the direction described or the direction shown in the accompanying drawings. These relative terms are for ease of description and are not generally intended to require a specific direction.

[0033] like Figures 1 to 12 As shown, the circulating cooling tempered glass air grille assembly includes an upper air grille assembly 9 and a lower air grille assembly 12 arranged opposite each other, with a gap formed between the upper air grille assembly and the lower air grille assembly for the tempered glass to pass through.

[0034] The upper air grille assembly has a set of upper air blades at its lower part, and the lower air grille assembly has a set of lower air blades at its upper part. The upper and lower air blades are arranged correspondingly, and the glass is cooled and tempered by the air blades 11. Both the upper and lower air grille assemblies have built-in cooling circulation pipes 18 inside, and both the upper and lower air grille assemblies have cooling circulation inlet pipes 2 and cooling circulation outlet pipes 3 that are connected to the corresponding built-in cooling circulation pipes.

[0035] The built-in circulating cooling tempered glass air grating utilizes the existing equipment structure, improving upon the air grating of a photovoltaic glass tempering furnace. Cooling circulating water pipes are installed inside the grating, altering the temperature and humidity within the grating without affecting airflow or reducing air pressure. The built-in circulating water pipes are located on the outside of the grating, effectively creating a heat insulation layer inside. Because the water in the circulating pipes is constantly flowing, the absorbed heat is carried away through water circulation, improving humidity within the grating during this heat exchange process. The flowing water partially isolates the grating from the outside environment, lowering the internal temperature and increasing humidity. Due to the close proximity of the grating to the glass, the cooled and humidified air is promptly and unimpeded to both sides of the glass, thus reducing the operating frequency of the fan. The circulated hot water can be used in the upstream glass washing machine; after passing through a water treatment system, the water can be recycled, reducing power consumption and saving energy.

[0036] like Figure 1 As shown, both the upper and lower air grille assemblies include a set of air grille units arranged side by side; specifically, the upper air grille assembly includes four upper air grille units arranged side by side, and the lower air grille assembly includes four lower air grille units arranged side by side; each air grille unit is equipped with a set of air blades, resulting in efficient glass cooling and tempering.

[0037] The upper air grid assembly is provided with an air pressure balance plate 10 between adjacent upper air blades to control air pressure and prevent deformation during glass tempering, and the lower air grid assembly is provided with a glass conveying roller 20 between adjacent lower air blades. The air pressure balance plate is located directly above the glass conveying roller 20. The air pressure balance plate and the glass conveying roller 20 are arranged correspondingly, with a compact structure and stable operation.

[0038] The built-in cooling circulation pipes of adjacent air vent units are connected by circulation pipe connecting pipe 13. Furthermore, a group of air vent units share a set of cooling circulation inlet and outlet pipes, which are connected to the corresponding cooling circulation inlet and outlet pipes by setting external cooling circulation pipes. An upper water pipe connecting seat 4 is set for the upper air vent unit, and a lower water pipe connecting seat 5 is set for the lower air vent unit. The water pipe structure is integrated and compact, which is conducive to layout and installation.

[0039] The upper grille assembly includes an upper grille connector 17 and an upper grille cavity. The upper grille connector is located above the upper grille cavity and has an upper air inlet pipe 1. An upper mounting hole is provided on the side of the upper grille connector. The upper grille cavity has a cavity structure that is smaller at the top and larger at the bottom, with built-in cooling circulation pipes arranged within the cavity structure. The upper air inlet pipe is relatively small compared to the cavity structure. The lower grille assembly includes a lower grille connector 16 and a lower grille cavity. The lower grille connector is located below the lower grille cavity and has a lower air inlet pipe 7. A lower mounting hole is provided on the side of the lower grille connector. The lower grille cavity has a cavity structure that is smaller at the bottom and larger at the top, with built-in cooling circulation pipes arranged within the corresponding cavity structure. The lower air inlet pipe is relatively small compared to the cavity structure. Airflow enters the cavity structure through the air inlet pipe. Since the cavity structure is relatively large, the built-in cooling circulation pipes within the cavity structure have minimal impact on airflow.

[0040] Each of the aforementioned air grating units is provided with a set of air blades arranged side by side. Each air blade is provided with an air grating liner 15. The air grating liner has a concave structure corresponding to the air inlet pipe position, which has little impact on airflow. The cooling circulation water inlet pipe and the cooling circulation water outlet pipe are both connected to the cooling circulation water inlet pipe and the cooling circulation water outlet pipe of each air grating unit through a connecting hose 25.

[0041] Each air knife within the air grille unit has an internal cooling circulation pipe, and a set of internal cooling circulation pipes within the air grille unit are connected in series. Furthermore, the internal cooling circulation pipes have a figure-eight structure, and the series connection points are located close to the inner wall of the cavity structure, minimizing their impact on airflow.

[0042] Each air grating unit is equipped with an air inlet pipe, and a group of air knives are arranged side by side within the overall cavity structure of the air grating unit. Specifically, the air grating and air knife structures are installed together with the air grating cavity, the outer liner of the air grating is connected to the inlet pipe, and the outer liner of the air grating is connected to the outside of the air grating cavity through an air grating connecting plate. An inner liner of the air grating is provided for each air knife, and there are hot air vents 8 between adjacent inner liners of the air grating for efficient heat dissipation.

[0043] A preferred embodiment of the present invention is as follows: The air grate assembly is a key structure of the glass tempering furnace, significantly impacting the product quality, yield, and energy consumption of the tempered glass. The built-in circulating cooling tempered glass air grate consists of four upper air grate sets, four lower air grate sets, and a set of inlet and outlet water pipes.

[0044] The air inlet of each air grating is located at the lower part of the upper and lower air gratings. The high-pressure fan enters through the air inlet and exits through the holes arranged on the air knife, blowing onto the upper and lower surfaces of the glass to rapidly cool the glass at around 600 degrees Celsius, thus tempering the photovoltaic glass. Each air grating has one water inlet and one water outlet, and each air grating has six air knives. The air knives are made of aluminum profiles, the upper and lower air grating cavities are made of steel plates, and the internal and external circulating water pipes are made of aluminum profiles and aluminum tubes. The water inlet pipe is connected to the water inlet of each air grating with a flexible hose, and the water outlet pipe is connected to the water outlet of each air grating with a flexible hose.

[0045] The upper grille assembly consists of 4 grille sets, each of which is fixed to the upper grille connecting seat with bolts. After horizontal adjustment, the upper grille assembly can be adjusted up and down. The lower grille assembly also consists of 4 grille sets, each of which is fixed to the lower grille connecting seat with bolts. After horizontal adjustment, the lower grille assembly can be adjusted up and down.

[0046] The air knife is made of aluminum profile and embedded in the lower part of the air grid cavity, sealed to the lower part of the air grid cavity with rivets and casting adhesive. Several holes are arranged at the bottom of the air knife, allowing air from the high-pressure blower to enter the air grid through ducts, changing the air's temperature and humidity. The air is then blown onto the glass surface through the holes, rapidly cooling and tempering the glass. The air grid cavity is hollow, and connecting pins 19 secure the steel plate on the same air knife, preventing deformation of the air grid cavity.

[0047] A pressure balancing plate is installed between two adjacent air knives in the upper air grid. Since there are glass conveying rollers between two adjacent air knives in the lower air grid, a pressure balancing plate is installed between the two air knives in the upper air grid to prevent deformation during glass tempering. The hot air vent structure includes multiple hot air vents located between two adjacent air grid cavities and between two sets of air grids. High-temperature resistant ceramic fiber ropes are wound around the surface of the glass conveying rollers, allowing glass at approximately 600 degrees Celsius to quickly pass through its surface for tempering.

[0048] The upper air grate connecting seat is welded to the air grate cavity and the air grate outer liner 14, and the lower air grate connecting seat is bolted to the tempering furnace lifting structure; the lower air grate connecting seat is welded to the air grate cavity and the air grate outer liner 15, and the lower air grate connecting seat is bolted to the tempering furnace lifting structure. The outer liner of the air grating is located at the lower part of the air inlet, welded to the air grating cavity at the bottom and connected to the inner liner of the air grating in the middle. Adjacent inner liners of the air grating are welded together by a flanged structure, and the middle area of ​​the inner liner of the air grating has a hollow structure. The inner liner of the air grating is located in the middle of the air grating cavity, welded to the air grating cavity at the bottom and connected to the outer liner of the air grating at the top. There are multiple air grating connecting plates 26, which connect adjacent air grating cavities to prevent deformation of the air grating cavity and increase the overall strength of the air grating.

[0049] The air inlet is located at the top of the upper air grating and is welded to the upper part of the outer lining plate of the air grating. A flexible hose made of canvas is connected to the air box and the upper air inlet, through which high-pressure air enters the upper air grating. The lower air inlet is located at the bottom of the air grating and is welded to the lower part of the lower air grating cavity. A flexible hose made of canvas is connected to the air box and the lower air inlet, through which high-pressure air enters the lower air grating.

[0050] The built-in cooling circulation pipes are divided into upper and lower layers, with a staggered arrangement between the two layers. The circulation pipe connecting pipes passes through two adjacent air grille cavities to connect the built-in cooling circulation pipes. The circulation pipe connecting pipes are made of different materials than the air grille cavities and are sealed with casting adhesive. The external cooling circulation pipe 6 connects to the built-in cooling circulation pipes. After passing through the outer liner of the air grille, a section of the cooling circulation pipe is placed on the outside of the air grille cavity, and after passing through the outer liner of the air grille again, it enters the inside of the air grille cavity. Because there is no installation space inside the air grille cavity, each air grille has only one external cooling circulation pipe, which is located on one side of the cooling circulation water outlet pipe.

[0051] One end of the inlet pipe 21 is connected to the water supply system, and the other end of the air grating inlet hose 23 is connected to multiple inlet pipes of the air grating; one end of the outlet pipe 22 is connected to multiple outlet pipes of the air grating through the air grating outlet hose 24, and the other end is connected to the water treatment and recycling system.

[0052] This solution adds an internal cooling circulation pipe to the air grating of a traditional photovoltaic glass tempering furnace. This allows for precise temperature and humidity control of the air grating without affecting air pressure and airflow. The solution offers multiple advantages, including optimized structure, high cooling efficiency, reduced energy consumption, stable operation, energy saving and environmental protection, and strong adaptability, as detailed below: Without affecting wind pressure and airflow, the cooling and humidity control effect is significant: The built-in cooling circulation pipe is reasonably arranged, without occupying the main airflow channel or reducing wind pressure. At the same time, the circulating water continuously removes heat from the air grille, effectively reducing the internal temperature of the air grille and increasing the internal humidity. It can promptly apply low-temperature, humid airflow to the glass surface, resulting in a better tempering cooling effect.

[0053] Reduce fan energy consumption and save operating costs: After the temperature and humidity of the fan grille are optimized, the operating frequency of the fan can be directly reduced, thus reducing power consumption; the recycled water after circulation heating can be recovered to the glass washing machine for reuse, and in conjunction with the water treatment system, water circulation can be realized, which can greatly save water resources and energy and improve economic efficiency.

[0054] Compact and integrated structure, convenient installation and layout: multiple sets of air grid units share a set of inlet and outlet water pipes, and the water pipes are connected to the hoses with integrated connectors, and the external pipe layout is reasonable; the air grid cavity, inner lining plate, connecting plate and other structures are designed as an integrated structure, which is compact and regular, and facilitates on-site installation, commissioning and later maintenance.

[0055] Stable tempering quality effectively prevents glass deformation: A pressure balance plate is installed between adjacent air knives in the upper air grid, which works in conjunction with the glass conveying rollers at the corresponding position in the lower air grid to balance the air pressure and prevent deformation during the glass tempering process; the air knives are evenly distributed and the hot air dissipation vents are reasonably designed, so that the glass is heated and cooled more evenly, improving the yield and product quality.

[0056] High structural strength, reliable and durable operation: The air grid cavity is made of steel plate and reinforced with air grid connecting plate and connecting pins to prevent cavity deformation; the air knife and cavity are sealed with rivets and casting adhesive, and the pipe connection is also sealed, resulting in excellent overall sealing performance and structural strength, suitable for high temperature continuous working conditions; the conveyor rollers are wound with high temperature resistant ceramic fiber rope, which can smoothly convey high temperature glass.

[0057] Highly adaptable and adjustable: Both the upper and lower air grilles can be adjusted up and down, and the horizontal position can be precisely adjusted to meet the tempering requirements of photovoltaic glass of different thicknesses and specifications; the cavity adopts a gradient structure, the air inlet pipe matches the cavity volume, the airflow is evenly distributed, and it is compatible with the retrofitting of existing tempering furnace equipment.

[0058] Balancing heat insulation and heat utilization: The built-in circulation pipe acts as an internal insulation layer for the air grating, reducing external heat conduction; the circulating water actively exchanges heat and recovers waste heat, which not only improves the internal environment of the air grating but also realizes the resource utilization of waste heat, meeting the production requirements of energy conservation and consumption reduction.

[0059] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0060] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
