Technical Field
[0001] This utility model relates to the technical field of air supply mechanisms, and in particular to an adjustable air supply mechanism. Background Technology
[0002] An air supply mechanism is a device or system used to transport air from one place to another. There are various types of existing air supply mechanisms; for example, a blower is a type of air supply mechanism. A blower is a machine used for wind power transmission, delivering air or gas into the machine's interior through air supply to achieve purposes such as control, pressurization, drying, heat exchange, or combustion. For example, when a blower is used in a boiler, it delivers outside air into the boiler, allowing the fuel inside to burn completely, greatly improving operating efficiency.
[0003] However, the size of the blower's outlet is usually fixed, which makes it impossible for operators to adjust the blower's air volume according to work needs. This not only increases the blower's energy consumption, but also causes dust inside the boiler to scatter everywhere due to excessive air volume, thus polluting the environment.
[0004] In addition, boilers come in a wide variety of types and sizes, which means that the height of the combustion port of each boiler is different. This makes it difficult for existing blowers to adjust the height of the air outlet according to the height of the boiler's combustion port, resulting in a narrow range of applications and making it difficult to adapt to different types of boilers. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable air supply mechanism, which has the advantages of adjusting the air supply volume and the height of the device, thus solving the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: an adjustable air supply mechanism, including a base plate, on which two mounting blocks are symmetrically distributed and fixedly installed. The interior of each mounting block is hollow. A blower body is arranged directly above the two mounting blocks. A hollow cylinder is threadedly connected to the air outlet of the blower body. The cross-section of the hollow cylinder is T-shaped. An air duct is arranged on one side of the hollow cylinder. An adjustment mechanism is arranged inside the hollow cylinder. A lifting mechanism is arranged inside each of the two mounting blocks. A filter mechanism is arranged at the air inlet of the blower body.
[0007] By adopting the above technical solution, the staff can adjust the air volume of the blower body according to the work requirements, thereby reducing the wear and tear of the blower body. At the same time, it can also prevent the dust in the boiler from being scattered indiscriminately due to excessive air volume, thus polluting the environment. Afterwards, the staff can adjust the height of the blower body according to the height of the boiler's combustion port, so that the blower body can be used for different types of boilers, expanding the scope of application.
[0008] Preferably, the adjustment mechanism includes a circular plate rotatably installed inside the hollow cylinder. A rectangular groove is formed in the middle of the circular plate, and a ventilation opening is formed on one side of the inner wall of the rectangular groove. Six sliding grooves are arranged in a circular array on the side of the hollow cylinder near the air duct. Six adjusting plates are evenly arranged on the side of the circular plate near the sliding grooves. The six adjusting plates are all equilateral triangles. A sliding rod is fixedly installed on one side of each of the six adjusting plates. The six sliding rods can slide in the six sliding grooves respectively. A slider is fixedly installed on the other side of each of the six adjusting plates. The six sliders can slide in the rectangular grooves. A connecting plate is fixedly installed on the outer surface of the circular plate, and the connecting plate penetrates the hollow cylinder.
[0009] By adopting the above technical solution, the staff can adjust the air volume of the blower body according to the work needs, thereby reducing the wear and tear of the blower body and preventing excessive air volume from causing dust in the boiler to spread and pollute the environment.
[0010] Preferably, the lifting mechanism includes two curved plates symmetrically distributed and fixedly installed inside the two mounting blocks. A pin-tooth chain is slidably mounted on each of the two curved plates, with one end of each pin-tooth chain penetrating the mounting block. A rotating shaft is rotatably mounted between the two mounting blocks. A motor is mounted on the upper surface of the base plate, and one end of the rotating shaft penetrates one of the mounting blocks and is fixedly connected to the motor's output shaft. Two gears are symmetrically distributed and fixedly fitted onto the outer surface of the rotating shaft. The two gears are located inside the two mounting blocks and mesh with one of the pin-tooth chains. Lifting blocks are fixedly mounted at the top ends of the two pin-tooth chains, and a blower body is positioned on top of the two lifting blocks.
[0011] By adopting the above technical solution, operators can adjust the height of the blower body according to the height of the boiler's combustion port, making the blower body suitable for different types of boilers and expanding its application range.
[0012] Preferably, the filtration mechanism includes a filter cover threaded onto the air inlet pipe of the blower body, an arc-shaped plate slidably inserted into the air inlet of the blower body, an activated carbon mesh plate provided on the inner surface of the arc-shaped plate and located inside the air inlet pipe of the blower body, a threaded post fixedly installed on the outer surface of the activated carbon mesh plate, and the bottom end of the threaded post penetrating through the air inlet pipe of the blower body, and a nut threaded onto the outer surface of the bottom end of the threaded post.
[0013] By adopting the above technical solution to filter the air drawn into the blower body, dust and other impurities in the air are prevented from being drawn into the blower body, thus avoiding damage to the blower body. At the same time, it can also reduce the frequency of cleaning the blower body by the staff.
[0014] Preferably, the lower surface of the base plate is provided with an anti-slip pad.
[0015] The above-mentioned technical solutions are used to improve the friction between the base plate and the ground.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-6 An adjustable air supply mechanism includes a base plate 1. Two mounting blocks 2 are symmetrically distributed and fixedly installed on the upper surface of the base plate 1. The interior of the two mounting blocks 2 is hollow. A blower body 3 (the blower body 3 is prior art, and its specific structure and principle are not described in this utility model) is arranged directly above the two mounting blocks 2. A hollow cylinder 4 is threadedly connected to the air outlet of the blower body 3. The cross-section of the hollow cylinder 4 is T-shaped. An air duct 5 is arranged on one side of the hollow cylinder 4. An adjustment mechanism is arranged inside the hollow cylinder 4. A lifting mechanism is arranged inside the two mounting blocks 2. A filter mechanism is arranged at the air inlet of the blower body 3.
[0028] Please see Figures 2-4 The adjustment mechanism includes a circular plate 6 rotatably installed inside the hollow cylinder 4. A rectangular groove 61 is provided in the middle of the circular plate 6. A vent 7 is provided on one side of the inner wall of the rectangular groove 61. Six sliding grooves 9 are arranged in a circular array on the side of the hollow cylinder 4 near the air duct 5. Six adjusting plates 10 are evenly arranged on the side of the circular plate 6 near the sliding grooves 9. The six adjusting plates 10 are all equilateral triangles. A sliding rod 11 is fixedly installed on one side of each of the six adjusting plates 10. The six sliding rods 11 can slide in the six sliding grooves 9 respectively. A slider 12 is fixedly installed on the other side of each of the six adjusting plates 10. The six sliders 12 can slide in the rectangular groove 61. A connecting plate 13 is fixedly installed on the outer surface of the circular plate 6 and penetrates the hollow cylinder 4.
[0029] Please see Figure 1 and Figure 5The lifting mechanism includes two curved plates 14 symmetrically distributed and fixedly installed inside two mounting blocks 2. Pin-tooth chains 15 are slidably mounted on both curved plates 14, with one end of each pin-tooth chain 15 penetrating the mounting block 2. A rotating shaft 16 is rotatably mounted between the two mounting blocks 2. A motor 17 is installed on the upper surface of the base plate 1, and one end of the rotating shaft 16 penetrates one of the mounting blocks 2 and is fixedly connected to the output shaft of the motor 17. Two gears 18 are symmetrically distributed and fixedly fitted onto the outer surface of the rotating shaft 16. The two gears 18 are located inside the two mounting blocks 2 and mesh with one of the pin-tooth chains 15. Lifting blocks 19 are fixedly installed at the top ends of the two pin-tooth chains 15. The blower body 3 is located on top of the two lifting blocks 19. The rotating shaft 16 can also be rotated manually, i.e., a handle is installed at the end of the rotating shaft 16 that penetrates one of the mounting blocks 2. When adjusting the height of the blower body 3, the operator can directly rotate the handle to drive the rotating shaft 16 to rotate, thereby adjusting the height of the blower body 3.
[0030] Please see Figure 1 and Figure 6 The filtration mechanism includes a filter cover 20 threaded onto the air inlet pipe of the blower body 3. An arc-shaped plate 21 is slidably inserted into the air inlet of the blower body 3. An activated carbon mesh plate 22 is provided on the inner surface of the arc-shaped plate 21 and is located inside the air inlet pipe of the blower body 3. A threaded post 23 is fixedly installed on the outer surface of the activated carbon mesh plate 22 and the bottom end of the threaded post 23 penetrates the air inlet pipe of the blower body 3. A nut 24 is threaded onto the outer surface of the bottom end of the threaded post 23.
[0031] Please see Figure 1 The bottom surface of the base plate 1 is provided with an anti-slip pad 25.
[0032] Working principle: During use, the blower body 3 can be installed on top of the two lifting blocks 19 by screws. Alternatively, the blower body 3 can be placed directly on top of the two lifting blocks 19. Then, the filter cover 20 can be threaded onto the air inlet pipe of the blower body 3. The filter cover 20 performs preliminary filtration of dust in the air. Then, the arc plate 21 is inserted from top to bottom onto the outside of the air inlet pipe of the blower body 3. At this time, the bottom end of the threaded post 23 will pass through the air inlet pipe of the blower body 3. Finally, the nut 24 is screwed onto the threaded post 23. At this time, the activated carbon mesh plate 22 can further filter the dust in the air.
[0033] When the height of the blower body 3 needs to be adjusted, the motor 17 can be started directly. The output shaft of the motor 17 drives the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will drive the gears 18 set in the two mounting blocks 2 to rotate. When the gears 18 rotate, they will drive one of the pin chain 15 to slide continuously on the curved plate 14 and gradually disengage from the curved plate 14. Since the two pin chains 15 are interlocked, when one pin chain 15 slides out from the top of the mounting block 2, it will also drive the other pin chain 15 to slide out of the mounting block 2 at the same time, thereby pushing the lifting block 19 to move upward, and then driving the blower body 3 to move upward, so that the height of the blower body 3 can be adjusted.
[0034] When it is necessary to adjust the air volume of the blower body 3, the connecting plate 13 can be rotated directly, so that the connecting plate 13 can rotate along the outer surface of the hollow cylinder 4. When the connecting plate 13 rotates, it will drive the circular plate 6 to rotate synchronously. When the circular plate 6 rotates, it will drive the slide rods 11 set on one side of the six adjusting plates 10 to slide in the six sliding grooves 9 respectively. At the same time, the slider 12 will also slide continuously along the rectangular groove 61. Finally, the six adjusting plates 10 continue to rotate, so that the sealing area of the six adjusting plates 10 on the ventilation opening 7 is smaller and smaller, until the ventilation opening 7 is no longer blocked. At this time, the air volume of the blower body 3 is the maximum. Afterwards, the operator can rotate the connecting plate 13 according to the needs, thereby adjusting the sealing area of the adjusting plate 10 on the ventilation opening 7, and thus adjusting the air volume.
