[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A low-resistance, high-efficiency flue gas distribution spiral core includes a fixed cylinder 1, a guide plate 2, a synchronous tilt angle adjustment mechanism 3, a spiral core cylinder 4, a self-locking flip-top mechanism 5, and a sealing cover plate 7; the fixed cylinder 1 is fixedly installed on the upper end of the reaction tower body 6; the spiral core cylinder 4 is fixedly connected to the inside of the fixed cylinder 1 through a bracket; the lower side of the spiral core cylinder 4 is conical;

[0037] An air inlet is provided at the upper end of the reaction tower body 6 to connect the reaction tower body 6, the fixed cylinder 1, and the volute cylinder 4;

[0038] Multiple guide plates 2 are rotatably mounted on the inner ends of both the fixed cylinder 1 and the volute cylinder 4; and the guide plates 2 on the fixed cylinder 1 and the volute cylinder 4 are fixedly connected by a connecting shaft; the guide plates 2 are evenly distributed in a circumferential array on the fixed cylinder 1 and the volute cylinder 4.

[0039] A synchronous tilt adjustment mechanism 3 for simultaneously controlling the rotation angle of multiple guide vanes 2 is installed at the outer end of the fixed cylinder 1;

[0040] The synchronous tilt adjustment mechanism 3 includes a movable component 32 that drives multiple guide plates 2 to rotate and a drive component 31 for controlling the movement of the movable component 32; the drive component 31 is installed at the outer end of the fixed cylinder 1, and the movable component 32 is connected to the drive component 31; and the movable component 32 is connected to the guide plate 2 at the inner end of the fixed cylinder 1.

[0041] A self-locking flip-top mechanism 5 for controlling the rotation angle of the sealing cover 7 is installed on the upper right side of the fixed cylinder 1; the sealing cover 7 is connected to the self-locking flip-top mechanism 5; and the sealing cover 7 is sealed and snapped into the upper end of the fixed cylinder 1.

[0042] A transition air inlet is provided at the upper middle part of the sealing cover plate 7;

[0043] The upper outer side of the sealing cover 7 is connected to the volute.

[0044] In this utility model, the flue gas to be treated enters the interior of the sealing cover 7 through the transition air inlet provided at the middle of the upper end of the sealing cover 7, and then flows downward into the fixed cylinder 1 and the volute cylinder 4.

[0045] Subsequently, the drive component 31 operates, driving the movable component 32 to move. The movable component 32 then drives the multiple guide plates 2 installed at the inner end of the fixed cylinder 1 to rotate. The rotation of the guide plates 2 at the inner end of the fixed cylinder 1 drives the guide plates 2 installed at the inner end of the volute cylinder 4 to rotate together. At this time, the guide plates 2 will tilt, and the flue gas can flow downward along the tilt direction of the guide plates 2 into the interior of the reaction tower 6. By driving the movable component 32 to move through the drive component 31, the device can synchronously and flexibly adjust the tilt angle of the multiple guide plates 2 according to the amount of flue gas to be processed, so that the multiple guide plates 2 are arranged in a spiral shape, stabilizing the flue gas flow direction, reducing the pressure difference, and avoiding the guide plates 2 being easily damaged by impact due to a large pressure difference, thus reducing the service life of the equipment.

[0046] During flue gas flow, particles in the flue gas accumulate and adhere to the surface of the guide plate 2. If it is not cleaned for a long time, it will affect the stability of the subsequent flue gas flow and reduce the service life of the guide plate 2. At this time, the sealing cover 7 can be flipped open by the self-locking flip-top mechanism 5, and the drive component 31 drives multiple guide plates 2 to rotate, so that the contact surface between the guide plate 2 and the flue gas is horizontally facing the upper end of the fixed cylinder 1. Then the operator can clean the dirt on the surface of the guide plate 2. After cleaning, the sealing cover 7 can be closed by the self-locking flip-top mechanism 5. Through the cooperation of the self-locking flip-top mechanism 5, the drive component 31 and the moving component 32, the operator can clean the guide plate 2 more quickly, reduce the standby time of the equipment and improve the practicality of the device.

[0047] like Figures 1-5 As shown, the movable component 32 includes a drive plate 321, a connecting plate 322, and a rotating shaft 323. Multiple rotating shafts 323 are rotatably mounted on the outer end of the fixed cylinder 1. The rotating shafts 323 are evenly distributed in a circumferential array on the outer wall of the fixed cylinder 1. The upper side of the drive plate 321 is fixedly connected to the rotating shaft 323. The guide plate 2 provided at the inner end of the fixed cylinder 1 is fixedly connected to the rotating shaft 323.

[0048] The drive plate 321 on the left side of the fixed cylinder 1 is configured as a drive unit; adjacent drive plates 321

[0049] Each space is hinged with a connecting plate 322;

[0050] The connecting plates 322 between adjacent drive boards 321 are arranged in a staggered, parallel configuration.

[0051] like Figures 1-5As shown, the drive assembly 31 includes a vertical plate 311, a servo motor 312, and a guide slide rod 314. The vertical plate 311 is fixedly installed on the upper left side of the reaction tower body 6. The servo motor 312 is fixedly installed on the left end of the vertical plate 311, and the output end of the servo motor 312 is fixedly connected to the outer end of the drive plate 321 at the drive unit position. The drive plate 321 of the drive unit rotates around the rotation shaft 323. The guide slide rod 314 is fixedly installed on the lower side of the inner end of the drive plate 321 of the drive unit.

[0052] The outer wall of the fixed cylinder 1 at the drive unit position is provided with a guide groove 313, and the guide slide rod 314 is connected to the guide.

[0053] The sliding connection to the groove 313 is limited;

[0054] In this utility model, the servo motor 312 drives the drive plate 321 of the drive unit to rotate along the guide groove 313 following the guide slide rod 314. The rotation of the drive plate 321 of the drive unit will drive the adjacent drive plates 321 to rotate simultaneously through the connecting plate 322. Subsequently, all the drive plates 321 will rotate together. The rotation of the drive plate 321 drives the rotating shaft 323 to rotate. The rotation of the rotating shaft 323 drives the guide plate 2 set at the inner end of the fixed cylinder 1 to rotate. The rotation of the guide plate 2 set at the inner end of the fixed cylinder 1 will drive the guide plate 2 set at the inner end of the volute cylinder 4 to rotate together. At this time, the tilt angle of multiple guide plates 2 will be changed synchronously.

[0055] like Figures 1-5 As shown, the self-locking flip-top mechanism 5 includes a bait plate 51, a ratchet 52, and a pawl 53.

[0056] The bait plate 51 is fixedly installed on the right side of the outer end of the fixed cylinder 1, along with the return spring 54; the right side of the outer end of the sealing cover 7 is rotatably installed in the middle of the bait plate 51; the ratchet 52 is rotatably installed at the front end of the bait plate 51, and the ratchet 52 is fixedly connected to the sealing cover 7.

[0057] The pawl 53 is rotatably mounted on the front end of the bait plate 51; one end of the return spring 54 is fixed to the bait plate 51.

[0058] Connection; the other end of the return spring 54 is fixedly connected to the pawl 53;

[0059] Ratchet 52 engages with pawl 53;

[0060] In this invention, when it is necessary to clean the guide plate 2, the sealing cover plate 7 is rotated upwards.

[0061] The rotation of the sealing cover 7 drives the ratchet 52 to rotate as well. The rotation of the ratchet 52 lifts the pawl 53, which in turn compresses the return spring 54 downwards. Each time the pawl 53 rotates a certain angle, the return spring 54 returns to its original position, causing the pawl 53 to re-engage with the ratchet 52, preventing the ratchet 52 from rotating downwards, until the sealing cover 7 is in a vertical position. Then, the servo motor 312 drives all the guide plates 2 to rotate, so that the contact surface between the guide plates 2 and the flue gas faces upwards. The operator can then clean the surface of the guide plates 2. After cleaning, the pawl 53 is pulled down to separate it from the ratchet 52. Then, the sealing cover 7 is flipped over and re-engaged with the upper end of the fixed cylinder 1.

[0062] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
