Description

Technical Field

[0001] This utility model relates to the technical field of volute-type air distributors, and in particular to a volute-type air distributor with adjustable air volume. Background Technology

[0002] A volute-type air distributor is an airflow guiding device used in industrial combustion systems. Its core structure is a spiral volute air duct that converts incoming air into a rotating jet, enhancing fuel-air mixing efficiency. It typically does not contain a power component (such as an impeller) but relies on an external fan to provide air pressure, controlling airflow distribution by adjusting the internal airflow guiding structure or damper opening.

[0003] The volute-type air distributor is mainly used in combustion scenarios that require enhanced airflow mixing, such as the secondary air system of coal-fired boilers, the air distribution optimization of biomass gasifiers, and the efficient combustion control of industrial kilns. In circulating fluidized bed boilers, it can ensure that the bed material is in full contact with the air, and in gas burners, it can form a stable swirling flame.

[0004] Currently, the air intake volume of a volute-type air distributor depends entirely on the air delivery capacity of the upstream fan, lacking independent dynamic adjustment capabilities. When the combustion load changes, the air volume can only be indirectly controlled by adjusting the fan speed or damper opening. This not only results in a slow response speed but also insufficient air volume adjustment accuracy. This passive reliance on external air sources makes it difficult for the system to match the needs of different fuels or operating conditions in real time, affecting combustion efficiency and potentially causing energy waste. Therefore, a volute-type air distributor with adjustable air volume is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable air volume volute air distributor, which aims to improve the problem of "lack of active adjustment of air volume in volute air distributors" mentioned in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a volute-type air distributor with adjustable air volume, comprising a body, wherein the side wall of the body is provided with an adjustment mechanism and a cleaning mechanism;

[0007] The adjustment mechanism includes a slide rail, which is fixedly installed on the side wall of the machine body. A slider is slidably connected to the inner wall of the slide rail. A baffle is fixedly installed on the side of the slider away from the slide rail. A gear ring is rotatably connected to the side wall of the machine body. A connecting rod is hinged to the inner wall of the gear ring. A motor is fixedly installed on the outer wall of the machine body. A rotating shaft is fixedly installed at the output end of the motor. A gear is fixedly installed on the outer wall of the rotating shaft. A protective net is fixedly installed on the outer wall of the gear ring.

[0008] As a further description of the above technical solution:

[0009] The cleaning mechanism includes a fixed rod, one end of which is fixedly installed on the outer wall of the machine body, and the other end of which is hinged to a brush. A through groove is provided on the brush, and an eccentric rod is fixedly installed on the outer wall of the gear.

[0010] As a further description of the above technical solution:

[0011] The eccentric rod and the rotating shaft are in an eccentric state, and the outer wall of the eccentric rod is attached to the through groove.

[0012] As a further description of the above technical solution:

[0013] The end of the connecting rod furthest from the gear ring is hinged to the side wall of the slider.

[0014] As a further description of the above technical solution:

[0015] The gear ring meshes with the gear.

[0016] As a further description of the above technical solution:

[0017] The baffle has a triangular structure, with the side of the baffle closest to the body attached to the outer wall of the body.

[0018] As a further description of the above technical solution:

[0019] The baffle is provided in six sets, and the gaps between the six sets of baffles form a hexagonal structure.

[0020] As a further description of the above technical solution:

[0021] The brush is attached to the outer wall of the protective net.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotation of the gear ring, in conjunction with the connecting rod and the slider, can drive multiple sets of baffles to move closer or further apart, thereby adjusting the size of the hexagonal structure formed between the six sets of baffles, and thus accurately controlling the air intake of the machine body to match the needs of different fuels or working conditions in real time.

[0024] 2. In this utility model, the rotation of the gear, in conjunction with the eccentric rod and the through groove, can drive the brush to reciprocate on the outer wall of the fixed rod. The reciprocating rotation of the brush can sweep off the impurities attached to the surface of the protective net, preventing the impurities from adhering to the surface of the protective net and affecting the air intake of the machine.

[0030] 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.

[0031] Reference Figures 1-3 One embodiment of this utility model is a volute-type air distributor with adjustable air volume, including a body 1, and an adjustment mechanism 2 and a cleaning mechanism 3 are provided on the side wall of the body 1.

[0032] Reference Figures 1-3The adjustment mechanism 2 includes a slide rail 21, which is fixedly installed on the side wall of the body 1. A slider 22 is slidably connected to the inner wall of the slide rail 21. The position of the baffle 23 can be adjusted by the cooperation of the slide rail 21 and the slider 22. The baffle 23 is fixedly installed on the side of the slider 22 away from the slide rail 21. The baffle 23 can block the air inlet of the body 1 to adjust the air intake. The baffle 23 has a triangular structure. The side of the baffle 23 closest to the body 1 is attached to the outer wall of the body 1. There are six sets of baffles 23. The gaps between the six sets of baffles 23 form a hexagonal structure. When the six sets of baffles 23 move away from each other, the hexagonal structure formed by the six sets of baffles 23 will gradually increase. When the six sets of baffles 23 move closer to each other, the hexagonal structure formed by the six sets of baffles 23 will gradually decrease. A gear ring 2 is rotatably connected to the side wall of the body 1. 4. A connecting rod 25 is hinged to the inner wall of the gear ring 24. The end of the connecting rod 25 away from the gear ring 24 is hinged to the side wall of the slider 22. When the gear ring 24 rotates, it can drive the slider 22 to slide on the inner wall of the slide rail 21 in conjunction with the connecting rod 25. A motor 26 is fixedly installed on the outer wall of the machine body 1. A rotating shaft 27 is fixedly installed at the output end of the motor 26. A gear 28 is fixedly installed on the outer wall of the rotating shaft 27. When the motor 26 is started, it drives the rotating shaft 27 to rotate clockwise. When the rotating shaft 27 rotates, it drives the gear 28 to rotate synchronously. The gear ring 24 meshes with the gear 28. When the gear 28 rotates, it drives the gear ring 24 to rotate on the side wall of the machine body 1. A protective net 29 is fixedly installed on the outer wall of the gear ring 24. The protective net 29 can prevent impurities from entering the interior of the machine body 1 with the airflow, thereby protecting the equipment inside the machine body 1.

[0033] Reference Figures 1-3 The cleaning mechanism 3 includes a fixed rod 31. One end of the fixed rod 31 is fixedly installed on the outer wall of the body 1, and the other end of the fixed rod 31 is hinged to a brush 32. The fixed rod 31 can support the brush 32. The brush 32 is attached to the outer wall of the protective net 29. While the brush 32 is reciprocating, it can sweep off the impurities attached to the surface of the protective net 29, preventing the impurities from being attached to the surface of the protective net 29 and affecting the air intake of the body 1. A through groove 33 is opened on the brush 32. An eccentric rod 34 is fixedly installed on the outer wall of the gear 28. While the gear 28 is rotating, it will drive the eccentric rod 34 to make a circular motion around the rotating shaft 27. The outer wall of the eccentric rod 34 is attached to the through groove 33. While the eccentric rod 34 is making a circular motion around the rotating shaft 27, it can drive the brush 32 to reciprocate on the outer wall of the fixed rod 31.

[0034] Working principle: When in use, the starter motor 26 drives the rotating shaft 27 to rotate clockwise. The rotation of the rotating shaft 27 drives the gear 28 to rotate synchronously. The rotation of the gear 28 drives the gear ring 24 meshing with it to rotate counterclockwise on the side wall of the body 1. The counterclockwise rotation of the gear ring 24 pushes the connecting rod 25, which in turn pushes the slider 22. At this time, the slider 22 slides on the inner wall of the slide rail 21. As the slider 22 slides, it drives the baffle 23 to move synchronously. At this time, the multiple baffles 23 will move away from each other. As the multiple baffles 23 move away from each other, the hexagonal space they form will gradually increase, thereby increasing the air intake of the body 1.

[0035] When the motor 26 drives the rotating shaft 27 to rotate counterclockwise, the rotating shaft 27 will drive the gear 28 to rotate synchronously. The gear 28 will drive the gear ring 24 meshing with it to rotate clockwise on the side wall of the machine body 1. The gear ring 24 will pull the connecting rod 25 while rotating clockwise, so that the connecting rod 25 pulls the slider 22. At this time, the slider 22 will slide on the inner wall of the slide rail 21. While the slider 22 is sliding, it will drive the baffle 23 to move synchronously. At this time, multiple baffles 23 will approach each other. When multiple baffles 23 approach each other, the hexagonal space they form will gradually shrink, thereby reducing the air intake of the machine body 1. This allows for flexible adjustment of the air intake of the machine body 1 to match different fuel or operating conditions in real time.

[0036] As gear 28 rotates, it drives eccentric rod 34 to make circular motion around shaft 27. At the same time, eccentric rod 34 moves back and forth against the inner wall of through groove 33 and pushes and pulls brush 32 back and forth, causing brush 32 to rotate back and forth on the outer wall of fixed rod 31. As brush 32 rotates back and forth, it can sweep off the impurities attached to the surface of protective net 29, preventing impurities from being attached to the surface of protective net 29 and affecting the air intake of body 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
