Description

Technical Field

[0001] The utility model relates to the field of quenching, and more specifically to a tempered glass spray quenching device. Background Art

[0002] Tempered glass is glass that has been strengthened by tempering to give it a compressive stress on the surface. After heating, tempered glass needs to be rapidly cooled to allow the surface of the glass to cool and harden first. The existing cooling methods mainly include air cooling and spray cooling. Compared with air cooling, spray cooling has the advantages of fast cooling speed and high efficiency, and can obtain better stress distribution, thereby improving the strength and stability of tempered glass.

[0003] When spray quenching tempered glass, a large amount of steam will be generated, which will carry a large amount of heat energy. However, existing spray quenching devices often do not have a structure to recover this heat energy, resulting in a certain amount of energy waste. Moreover, these water vapors will condense into water droplets and mist after accumulating and cooling in the equipment. The water droplets and mist will cause moisture and other problems in the equipment, thereby reducing the durability of the device.

[0004] Based on the above, the purpose of the utility model is to provide a tempered glass spray quenching device to solve the above problems. Utility Model Content

The utility model arranges a water storage tank and an atomizing nozzle to perform spray quenching on the tempered glass, and then arranges an exhaust hood to extract the steam generated in the cold extraction from the cooling chamber, and then returns the water vapor to the water storage tank through a conveying pipe for recycling. In this process, the fan will transport the heat energy of the water vapor in the circulation pipe to the tempered glass through the airflow for drying, thereby realizing the recovery and utilization of the heat energy of the water vapor.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a tempered glass spray quenching device, comprising a box body, the box body is provided with a feed port and a discharge port, a plurality of conveying rollers are rotatably connected to the box body, a driving mechanism for driving the conveying rollers to rotate is provided on the box body, the inner cavity of the box body is divided into a cooling chamber and a drying chamber, a water storage tank, a conveying pump 1 and a conveying pump 2 are provided on the box body, a plurality of atomizing nozzles and an exhaust hood are provided in the cooling chamber, a plurality of the atomizing nozzles are fixedly connected to the discharge port of the conveying pump 1, the feed port of the conveying pump 1 is fixedly connected to the water storage tank, a plurality of the exhaust hoods are fixedly connected to the feed port of the conveying pump 2, a conveying pipe with one end fixedly connected thereto is provided on the discharge port of the conveying pump 2, the other end of the conveying pipe is fixedly connected to the water storage tank after passing through the drying chamber, and a plurality of fans are provided at both upper and lower ends of the drying chamber.

[0007] By adopting the above technical scheme, when it is necessary to spray quench the tempered glass, the conveying roller is driven to rotate by the driving mechanism, and then the tempered glass to be processed is placed on the conveying roller through the feed port, and the conveying roller will send the tempered glass to the discharge port. In this process, the tempered glass will first pass through the cooling chamber, and the conveying pump 1 will extract the cold water in the water storage tank and spray quench the glass through the atomizing nozzle. During this period, the high-temperature water vapor generated will be extracted from the cooling chamber by the conveying pump 2 through the exhaust hood, and then sent to the conveying pipe. Then the glass passes through the cooling chamber to the drying chamber, and the fan will convey airflow to the tempered glass. The airflow will exchange heat with the conveying pipe, thereby increasing the temperature of the airflow, and then drying the tempered glass. In this process, the water vapor in the conveying pipe is condensed into water due to the heat exchange with the airflow, and finally returned to the water storage tank for standby. In this way, the high-temperature water vapor generated during the spray quenching will be extracted to prevent the accumulation in the equipment from condensing into water droplets and mist after cooling, thereby causing humidity in the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] A tempered glass spray quenching device, such as Figure 1-Figure 2 As shown, it includes a box body 1, a feed port 2 and a discharge port 3 are opened on the box body 1, a plurality of conveying rollers 4 are rotatably connected in the box body 1, and a driving mechanism for driving the conveying rollers 4 to rotate is provided on the box body 1. The driving mechanism can be a motor directly driving the conveying rollers 4, or a motor cooperates with transmission accessories such as chains, gears or pulleys to drive multiple conveying rollers 4 to rotate. How the motor drives the conveying rollers 4 to rotate is a mature existing technology and will not be elaborated here.

[0022] The inner cavity of the box body 1 is divided into a cooling chamber 5 and a drying chamber 6. A water tank 7, a delivery pump 1 8 and a delivery pump 2 9 are installed on the box body 1. A plurality of atomizing nozzles 10 and an exhaust hood 11 are installed in the cooling chamber 5. The plurality of atomizing nozzles 10 are fixedly connected to the discharge port 3 of the delivery pump 1 8, the feed port 2 of the delivery pump 1 8 is fixedly connected to the water tank 7, and the plurality of exhaust hoods 11 are fixedly connected to the feed port 2 of the delivery pump 2 9. A delivery pipe 12 is provided at one end of the discharge port 3 of the delivery pump 2 9, and the other end of the delivery pipe 12 is fixedly connected to the water tank 7 after passing through the drying chamber 6. A plurality of fans 13 are installed at the upper and lower ends of the drying chamber 6.

[0023] Furthermore, the delivery pipe 12 is spirally arranged in the drying chamber 6 .

[0024] Furthermore, a plurality of atomizing nozzles 10 are respectively installed at the upper and lower ends of the cooling chamber 5 .

[0025] Furthermore, the atomizing nozzle 10 located below the conveying roller 4 is staggered with respect to the conveying roller 4 .

[0026] Furthermore, a water storage tank is arranged below the box body 1, and a plurality of water seepage grooves 14 are arranged on one side of the cooling chamber 5 close to the water storage tank.

[0027] Working principle: when it is necessary to spray quench the tempered glass, the conveyor roller 4 is driven to rotate by the driving mechanism, and then the tempered glass to be processed is placed on the conveyor roller 4 through the feed port 2, and the conveyor roller 4 will send the tempered glass to the discharge port 3. In this process, the tempered glass will first pass through the cooling chamber 5, and the conveying pump 8 will draw out the cold water in the water tank and atomize the cold water through the atomizing nozzle 10, and then the glass will be spray quenched. Since the atomizing nozzles 10 are provided on the upper and lower sides of the conveyor roller 4, and the atomizing nozzles 10 are staggered with the conveyor roller 4, the upper and lower sides of the tempered glass can be subjected to cold quenching treatment, so that the cooling is more uniform.

[0028] During this period, the water mist will be transformed into high-temperature water vapor after absorbing the heat energy on the tempered glass. The high-temperature water vapor will be extracted from the cooling chamber 5 by the delivery pump 29 through the exhaust hood 11, and then sent to the delivery pipe 12. Then the tempered glass passes through the cooling chamber 5 to the drying chamber 6. The fan 13 will deliver airflow to the tempered glass. The airflow will exchange heat with the delivery pipe 12, thereby increasing the temperature of the airflow and drying the tempered glass. The spirally arranged delivery pipe 12 will increase its contact area with the airflow, making the heat exchange efficiency higher.

[0029] In the above process, the water vapor in the delivery pipe 12 cools down and condenses into water due to the heat exchange with the airflow, and finally returns to the water storage tank for standby. The water vapor remaining in the condensation chamber will condense into water and then drip into the water storage tank through the seepage groove 14.

[0030] It is also necessary to mention that the water tank needs to be equipped with a water treatment system to ensure the water quality of the cooling water to prevent water marks from being left on the glass surface or causing other quality problems. The water treatment system installed in the atomizing quenching equipment is a mature existing technology and will not be elaborated here.

[0031] With this arrangement, the high-temperature water vapor generated during spray quenching will be extracted to prevent it from accumulating in the equipment and condensing into water droplets and mist after cooling, thereby causing humidity in the equipment. The heat energy carried in the water vapor will also be used to dry the glass, thereby realizing the recovery of heat sources.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
