Description

Technical Field

[0001] This utility model relates to the field of galvanizing production technology, and in particular to a waste heat recovery device with hot air collection and guiding function for galvanizing production. Background Technology

[0002] The zinc pot temperature in the steel plate galvanizing production line needs to be maintained at around 500 degrees Celsius all year round. The induction unit is one of the main devices for heating the zinc pot. During operation, the induction unit itself needs to be cooled down. A large amount of electrical energy is converted into hot air and released into the environment. The released heat energy is fully utilized so that other hot air drying boxes do not need to be heated additionally. This not only reduces the production cost of the production line, but also improves the production line's ability to handle the insufficient equipment capacity for producing different specifications of products.

[0003] Existing hot air recovery devices often face a common problem when handling hot air generated during industrial production: while recovering and utilizing the hot air, they also easily introduce various impurities generated in the galvanizing production equipment into the hot air recovery system. These impurities may include metal dust, oil stains, and other fine particulate matter. Over time, these impurities gradually accumulate inside the hot air recovery device, especially forming deposits on key components such as filters or separators. This not only reduces filtration efficiency and affects the normal operation of the entire system, but may also lead to a decline in heat exchange performance and even blockage of pipes. To ensure the continuous and efficient operation of the equipment, maintenance personnel have to frequently clean and maintain the filter components, increasing operating costs and downtime, which is inconvenient to use. Therefore, we propose a waste heat recovery device with hot air collection and guidance function for galvanizing production, which has easy-to-use functions and urgently needs development. Utility Model Content

[0004] The purpose of this invention is to provide a waste heat recovery device with hot air collection and guidance function for galvanizing production. This device can avoid the problem that existing hot air recovery devices easily bring metal dust, oil and other impurities from galvanizing production equipment into the system when recovering industrial hot air. These impurities gradually accumulate on key components such as filters and separators, leading to reduced filtration efficiency, decreased heat exchange performance, and even pipe blockage.

[0005] This utility model provides a waste heat recovery device with hot air collection and guidance function for galvanizing production, including a transmission box. Air ducts are connected to both the front and rear sides of the transmission box. An exhaust valve is installed at one end of the front air duct, and a pipe is connected to the front end of the exhaust valve. Dust extraction fans are installed on both the left and right sides of the transmission box. A filter assembly is provided inside the transmission box, and the filter assembly includes a fixing box. Several fixing frames are fixedly connected to the inner cavity of the transmission box, and several first return springs are fixedly connected to the outer surface of the fixing frames. A suction device is installed inside the transmission box.

[0006] In one specific implementation, the inner cavity of the transmission box is slidably connected with a plurality of filter components, and one end of the first reset spring is fixedly connected to the outer surface of the filter components.

[0007] In one specific implementation, the inner cavity of the transmission box is fixedly connected to several long boxes, and the top of the inner cavity of each long box is rotatably connected to a connecting rod, with the bottom end of the connecting rod penetrating into the inner cavity of the fixed box.

[0008] In one specific implementation, the outer surface of the connecting rod is threaded with a threaded plate, the outer surface of the threaded plate is slidably connected to the inner cavity of the long box, a push rod is fixedly connected to the top of the threaded plate, and one end of the push rod passes through the inner cavity of the fixed box and is fixedly connected to a placement plate.

[0009] In one specific implementation, a second reset spring is fixedly connected to both sides of the rear side of the placement plate, and a cleaning plate is fixedly connected to one end of the second reset spring.

[0010] In one specific implementation, the outer surface of the cleaning plate is in contact with the outer surface of the filter component, and a motor is bolted to the inner cavity of the fixing box.

[0011] In one specific implementation, rotating rods are provided through both sides of the top of the inner cavity of the fixed box, and the top of the rotating rods extends to the bottom of the inner cavity of the transmission box.

[0012] In one specific implementation, a plurality of first pulleys are respectively fitted on the outer surfaces of a plurality of rotating rods, and the plurality of first pulleys are connected by belt drive. The rotating rods and their outer surfaces are respectively equipped with second pulleys.

[0013] In one specific implementation, several second pulleys are connected by belt drive, a disc is fixedly connected to the top of the rotating rod, and movable plates are slidably connected to both sides of the bottom of the transmission box cavity.

[0014] In one specific implementation, a round rod is fixedly connected to the top of the disc, the outer surface of the round rod is slidably connected to the inner side of the movable plate, and the outer surface of the movable plate is in contact with the outer surface of the filter component.

[0015] The beneficial effects of this application are as follows: By setting up the filter assembly, dust and other fine particulate matter in the hot air can be effectively intercepted and filtered. The filter assembly not only prevents impurities from entering the hot air recovery device, but also ensures that the filtered hot air is purer, thereby improving the overall performance of heat energy recovery efficiency. In addition, the filter assembly is generally easy to clean. Specifically, the moving plate pushes the filter component to squeeze the first return spring while moving, thereby causing the filter component to shake off the impurities attached to it. The threaded plate drives the push rod, the placement plate, the second return spring and the cleaning plate to move synchronously, thereby achieving the effect of cleaning the adsorbed impurities and reducing the problem of system performance degradation caused by impurity accumulation. This filter assembly not only helps to maintain a long-term stable hot air recovery effect and reduces downtime and operating costs, but also ultimately improves the economic benefits and environmental friendliness of the entire production process.

[0025] Existing hot air recovery devices often introduce impurities such as metal dust and oil from galvanizing production equipment into the system when recovering industrial hot air. These impurities gradually accumulate in key components such as filters and separators, leading to reduced filtration efficiency, decreased heat exchange performance, and even pipe blockage. Therefore, the inventors have developed a waste heat recovery device for galvanizing production with a hot air collection and guidance function. By setting up a filter assembly, dust and fine particles in the hot air can be effectively intercepted, preventing impurities from entering the hot air recovery device, ensuring the purity of the hot air, improving heat recovery efficiency and system performance, thereby solving the above-mentioned defects.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please refer to Figures 1 to 7This utility model provides a waste heat recovery device with hot air collection and guidance function for galvanizing production, including a transfer box 1. Air guide pipes 2 are connected to both the front and rear sides of the transfer box 1. An exhaust valve 3 is installed at one end of the front air guide pipe 2, and a pipe 4 is connected to the front end of the exhaust valve 3. Dust collectors 5 are installed on both the left and right sides of the transfer box 1. The output end of the dust collector 5 is connected to a pipeline, which penetrates into the inner cavity of the transfer box 1. The area where the pipeline contacts the transfer box 1 is sealed. The discharge of the dust collector 5... The end can be connected to an external dust storage device for easy storage of cleaning residue. The inner cavity of the transfer box 1 is equipped with a filter assembly 6, which includes a fixed box 61. The outer surface of the fixed box 61 is fixedly connected to the bottom of the transfer box 1. Several fixed brackets 62 are fixedly connected to the inner cavity of the transfer box 1, and several first return springs 63 are fixedly connected to the outer surface of the fixed brackets 62. A suction device 7, such as a heat-absorbing fan or an exhaust fan, is installed in the inner cavity of the transfer box 1. The inner cavity of the transfer box 1 is slidably connected... There are several filter components 64, which are made of materials such as activated carbon plates to adsorb zinc powder impurities. One end of the first return spring 63 is fixedly connected to the outer surface of the filter component 64. Several long boxes 65 are fixedly connected to the inner cavity of the transmission box 1. The top of the inner cavity of the long box 65 is rotatably connected to a connecting rod 66, and the bottom end of the connecting rod 66 penetrates into the inner cavity of the fixed box 61. The outer surface of the connecting rod 66 is provided with external threads, and a threaded plate 67 is threadedly connected to the outer surface of the connecting rod 66. The outer surface of the threaded plate 67 is connected to the long box 65. The inner cavity of 5 is slidably connected, and a push rod 68 is fixedly connected to the top of the threaded plate 67. One end of the push rod 68 passes through the inner cavity of the fixed box 61 and is fixedly connected to the placement plate 69. The area of ​​the push rod 68 in contact with the fixed box 61 is sealed. The two sides of the rear side of the placement plate 69 are fixedly connected to the second return spring 610. One end of the second return spring 610 is fixedly connected to the cleaning plate 611. The outer surface of the cleaning plate 611 is in contact with the outer surface of the filter component 64. The inner cavity of the fixed box 61 is bolted to the motor 612.

[0028] Specifically, when cleaning the impurities adsorbed by the filter component 64, the connecting rod 66 uses the threaded transmission principle to drive the threaded plate 67 to move up and down reciprocally. The threaded plate 67 drives the push rod 68, the placement plate 69, the second return spring 610 and the cleaning plate 611 to move synchronously. The cleaning plate 611 wipes the filter component 64 reciprocally, thereby cleaning out the impurities attached to the surface of the filter component 64.

[0029] Please refer to Figures 2 to 7Rotating rods 613 are provided through both sides of the top of the inner cavity of the fixed box 61. The top of the rotating rods 613 extends to the bottom of the inner cavity of the transmission box 1. The area of ​​contact between the rotating rods 613 and the transmission box 1 is sealed. Several first pulleys 614 are respectively sleeved on the outer surface of several rotating rods 613, and the several first pulleys 614 are connected by belt drive. Second pulleys 615 are respectively installed on the rotating rods 613 and their outer surfaces. Several second pulleys 615 are connected by belt drive. A disc 616 is fixedly connected to the top of the rotating rods 613. Movable plates 617 are slidably connected to both sides of the bottom of the inner cavity of the transmission box 1. A round rod 618 is fixedly connected to the top of the disc 616. The outer surface of the round rod 618 is slidably connected to the inner side of the moving plate 617. The outer surface of the moving plate 617 is in contact with the outer surface of the filter component 64.

[0030] Specifically, the suction device 7 is activated, drawing hot air into the transmission box 1. During the suction process, impurities in the airflow are intercepted and adsorbed by the filter component 64. Then, when the exhaust process stops, the motor 612 is activated. The motor 612 drives the rotating rod 613, the first pulley 614, the second pulley 615, the disc 616, and the round rod 618 to rotate. The first pulley 614 drives the connecting rod 66 to rotate. At this time, the rotating rod 613 drives the disc 616 to rotate, and the disc 616 drives the round rod 618 to rotate. While the round rod 618 is rotating, it pushes the moving plate 617 to move back and forth. As the moving plate 617 moves, it pushes the filter component 64 to squeeze the first return spring 63, thereby causing the filter component 64 to shake off the impurities attached to it. At this time, the second return spring 610 drives the cleaning plate 611 to contact the filter component 64 and reciprocate to clean it, thereby effectively cleaning off the attached impurities and making it easy to use.

[0031] In summary, the working principle of a waste heat recovery device with hot air collection and guidance function for galvanizing production according to an embodiment of this utility model is as follows: First, the user connects the pipe 4 to the galvanizing production pot, and the air guide pipe 2 connects to the air inlet of the fan of other drying boxes in the production line, which is conducive to the resource reuse of the collected hot air. When the connection is completed and it is necessary to collect the hot air in the galvanizing production pot, the exhaust valve 3 is opened first, and then the suction device 7 is started to draw the hot air into the transmission box 1 for storage and filtration. During the filtration process, the fixed box 61 intercepts and adsorbs impurities in the galvanizing production pot. When it is necessary to allow airflow to the filter component 64, the impurities can be cleaned and shaken by the filter component 6. After shaking, the dust and other impurities inside the transmission box 1 are removed by the dust suction fan 5, which is convenient for use.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
