Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a dual-circulation air duct infrared dryer. Background Technology

[0002] Infrared dryers play a vital role in modern industrial production and daily life. In the industrial sector, from food processing and textile printing and dyeing to electronics manufacturing, numerous industries require efficient and reliable drying equipment to remove moisture from materials, ensuring product quality, extending shelf life, or meeting the requirements of subsequent production processes. In daily life, infrared dryers greatly enhance convenience in scenarios such as drying clothes and tableware. As society's demands for production efficiency and quality of life continue to rise, the need for optimized infrared dryer performance is becoming increasingly urgent.

[0003] Currently, traditional infrared dryers typically employ relatively simple mechanical structures. They are primarily equipped with fixed infrared heating elements. These elements generate infrared rays when energized, heating the surrounding air through thermal radiation. The circulation of the hot air is driven by a simple fan, which generally rotates in only one direction, blowing the heated air from near the heating elements towards the drying area.

[0004] However, traditional infrared dryers have certain problems, namely, slow hot air circulation inside the equipment. Because the fan is only unidirectional and has limited airflow, and the duct design cannot effectively guide the hot air to circulate quickly and comprehensively within the drying chamber, the flow efficiency of hot air within the equipment is low. This results in infrequent renewal of the hot air around the objects, making it difficult to remove the evaporated moisture from the object's surface in a short time. Consequently, it is difficult to dry the objects quickly, and a significant amount of time is wasted on the slow circulation and heat transfer of hot air, greatly reducing the equipment's drying efficiency and failing to meet the growing demands for efficient production and daily life. Therefore, a dual-circulation duct infrared dryer is proposed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a dual-circulation air duct infrared dryer, which aims to improve the problem of slow internal hot air circulation and difficulty in quickly drying objects.

[0006] To achieve the above objectives, the present invention provides a modular, spliced ​​carbon fiber billiard cue:

[0017] As a further description of the above technical solution:

[0018] Each of the pulleys is rotatably connected to a support shaft, one end of which is fixedly connected to the inner wall of the drying oven.

[0019] As a further description of the above technical solution:

[0020] Each of the connecting strips has a slider fixedly connected to one side, and each slider has a connecting block slidably connected to its outer wall.

[0021] As a further description of the above technical solution:

[0022] Each of the connecting blocks has a connecting frame fixedly connected to one side, and each of the connecting frames has one side fixedly connected to the outer wall of the infrared drying lamp.

[0038] Reference Figures 1-4 An embodiment of this utility model is provided: a dual-circulation air duct infrared dryer, including a drying box 1, a workbench 2 fixedly connected to the inner wall of the drying box 1, a roller conveyor belt 3 fixedly connected to the inner wall of the workbench 2, a circulation component provided on the outer wall of the roller conveyor belt 3, and multiple infrared drying lamps 12 fixedly connected to the top of the inner wall of the drying box 1, with drying components provided on both sides of the infrared drying lamps 12.

[0039] The circulation assembly includes multiple bidirectional circulating fans 4, located on the outer wall of the roller conveyor belt 3. Their function is to drive the gas to circulate within the equipment. The bottom of each bidirectional circulating fan 4 is fixedly connected to the bottom of the inner wall of the workbench 2. Each bidirectional circulating fan 4 has an input pipe 6 fixedly connected to its input end, which draws in hot air from inside the drying chamber 1. Each input pipe 6 has a feed hopper 7 fixedly connected to its top, which guides the hot air into the input pipe 6. Each bidirectional circulating fan 4 has an output pipe 5 fixedly connected to its output end, which transports the hot air to the drying area. Each output pipe 5 has an outlet pipe 8 fixedly connected to one end, which evenly sprays the hot air onto the top of the objects. Each output pipe 5 has multiple fixed shells 11 fixedly connected to its inner wall, which serve to... Each fixed housing 11 has a fan impeller 13 rotatably connected to its inner wall. The function of the fan impeller 13 is to accelerate the flow speed of hot air inside the output pipe 5. Each output pipe 5 has multiple air vents 9 inside, which spray out some hot air to enhance the drying effect. Each output pipe 5 has multiple support blocks 10 fixedly connected to its outer wall. The function of the support blocks 10 is to support the rotating shaft 14. The rotating shaft 14 is rotatably connected between adjacent support blocks 10. The function of the rotating shaft 14 is to drive the fan impeller 15 to rotate. Each rotating shaft 14 has a fan impeller 15 fixedly connected to its outer wall. The function of the fan impeller 15 is to further accelerate the flow of hot air. Each fan impeller 15 has a triangular air guide plate 16 fixedly connected to its outer wall. The function of the triangular air guide plate 16 is to cut the hot air and change its flow direction to ensure that the hot air is evenly distributed.

[0040] Specifically, during the gas circulation process inside the equipment, the bidirectional circulating fan 4 draws hot air from inside the drying chamber 1 into the output pipes 5 on both sides through the input pipe 6 and the feed hopper 7, and the air moves in opposite directions. As the hot air flows through the output pipes 5, it drives the impeller 13 to rotate on one side of the fixed housing 11, thereby accelerating the flow speed of the hot air inside the output pipes 5. The rotation of the impeller 13 not only improves the flow efficiency of the hot air but also enhances the heat transfer effect. During the flow of hot air through the output pipes 5, some of the hot air is ejected through the vent 9 until it collides with the triangular air guide plate 16. The design of the triangular air guide plate 16... It can effectively change the direction of hot air flow, so that it works in conjunction with the impeller 15 to rotate around the shaft 14, further accelerating the flow of hot air. In addition, the sharp surface between the symmetrical inclined surfaces on both sides of the triangular air guide plate 16 can cut the hot air, causing the hot air to diffuse outward in different directions, ensuring that the hot air makes full contact with all surfaces of the drying item, improving the uniformity and efficiency of drying. The remaining heat inside the output pipe 5 will be sprayed to the top of the object through the air outlet pipe 8 to achieve comprehensive drying of the object. Through this multi-level hot air circulation and distribution mechanism, not only is the heat recycling effect enhanced, but the drying efficiency and quality are also significantly improved.

[0041] Reference Figure 2 and Figure 5The drying assembly includes multiple infrared drying lamps 26, located on both sides of the first infrared drying lamp 12. Their function is to uniformly heat the sides of the object through infrared radiation. Fixtures 17 are fixedly connected to both sides of the drying chamber 1. The fixtures 17 support motors 18 and provide a stable mounting base. Each fixture 17 has a motor 18 fixedly connected inside, providing power to drive pulley 19 to rotate. The output end of each motor 18 extends into the interior of the drying chamber 1 and is fixedly connected to pulley 19. The pulley 19 rotates to drive a connecting belt 20. Each pulley 19 has a connecting belt 20 on its outer wall, transmitting power and driving pulley 21 to rotate. Each connecting belt 20 has a pulley 21 on its inner wall. The function is to change the direction of movement of the connecting belt 20. Each pulley 21 is rotatably connected to a support shaft 22. The function of the support shaft 22 is to support the pulley 21 and ensure its stable rotation. One end of the support shaft 22 is fixedly connected to the inner wall of the drying chamber 1. Each connecting belt 20 is fixedly connected to one side of a slider 23. The function of the slider 23 is to achieve linear reciprocating movement through the movement of the connecting belt 20. Each slider 23 is slidably connected to the outer wall of a connecting block 24. The function of the connecting block 24 is to transmit the moving force of the slider 23 to the connecting frame 25. Each connecting block 24 is fixedly connected to one side of a connecting frame 25. The function of the connecting frame 25 is to support and fix the infrared drying lamp 26. Each connecting frame 25 is fixedly connected to the outer wall of the infrared drying lamp 26. The function of the infrared drying lamp 26 is to evenly dry the side of the object through reciprocating motion.

[0042] Specifically, during the drying process of the equipment, the motor 18 is started first, and the output end of the motor 18 drives the pulley 19 to rotate. The rotation of the pulley 19 transmits power through the connecting belt 20, causing the connecting belt 20 to move synchronously. As the connecting belt 20 moves, it drives the pulley 21 to rotate around the support shaft 22, thus transmitting power to the slider 23, causing the slider 23 to move synchronously. The moving force of the slider 23 is transmitted through the connecting block 24 and the connecting frame 25, pushing the infrared drying lamp 26 to move horizontally. When the slider 23 moves to both sides of the connecting belt 20, due to the internal structural design of the connecting block 24, the slider 23 will slide up and down inside the connecting block 24, and then push the infrared drying lamp 26 to move in the opposite direction, realizing the linear reciprocating motion of the infrared drying lamp 26, which can evenly cover the side area of ​​the object, ensuring that the side of the object is heated evenly. The reciprocating motion of the infrared drying lamp 26 not only improves the heat transfer efficiency, but also avoids the problems of local overheating or uneven drying, enhances the drying effect on the object, and improves the stability and reliability of the drying process.

[0043] Working principle: During the gas circulation process inside the equipment, the hot air inside the drying chamber 1 is drawn into the interior of the two-way circulating fan 4 through the input pipe 6 and the feed hopper 7 and moves in opposite directions. The hot air flowing inside the output pipe 5 drives the fan impeller 13 to rotate on one side of the fixed shell 11, thereby accelerating the flow speed of the hot air inside the output pipe 5. During the flow of the hot air inside the output pipe 5, some of the hot air will be ejected through the air outlet 9 until the hot air collides with the triangular air guide plate 16, causing the triangular air guide plate 16 and the fan impeller 15 to rotate around the rotating shaft 14, which further accelerates the flow speed of the hot air. The sharp surface between the symmetrical inclined surfaces on both sides of the triangular air guide plate 16 cuts the hot air, causing the hot air to diffuse outward in different directions, ensuring that the hot air makes full contact with all surfaces of the drying parts. The remaining heat inside the output pipe 5 will be sprayed onto the top of the object through the air outlet 8, ultimately achieving comprehensive drying of the object and enhancing the heat recycling effect of the equipment.

[0044] During the drying process, the motor 18 is started, and the output of the motor 18 drives the pulley 19 to rotate, causing the connecting belt 20 to move synchronously. As the connecting belt 20 moves, it drives the pulley 21 to rotate around the support shaft 22, and causes the slider 23 to move synchronously. The movement of the slider 23 pushes the infrared drying lamp 26 to move through the connecting block 24 and the connecting frame 25. When the slider 23 moves to both sides of the connecting belt 20, the slider 23 slides up and down inside the connecting block 24, and then pushes the infrared drying lamp 26 to move in the opposite direction, realizing the linear reciprocating motion of the infrared drying lamp 26, achieving comprehensive drying of the sides of the object, and enhancing the drying effect of the equipment.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
