Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a fan with an added airflow inlet guiding direction. Background Technology

[0002] The fan used in dust removal equipment is a general-purpose mechanical device designed specifically for separating and conveying dust-laden gas. Its core function is to draw dust particles from the production environment and transport them to the filtration system for purification by generating airflow. Axial flow fans are usually used.

[0003] Traditional axial flow fans typically have blades integrated with the rotating disk, or the blades are fixed to the rotating disk with multiple bolts. This method makes it difficult to adjust the blade angle, resulting in consistent airflow pressure. When different airflow pressures are required, the entire fan needs to be disassembled and replaced with a fan with a different blade angle, or the blades inside the fan need to be replaced individually. This is not only time-consuming and labor-intensive, but also involves a large workload and is inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a fan that increases the direction of airflow inlet guidance, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fan that enhances the direction of airflow inlet guidance, comprising a bent pipe, a motor support fixedly connected to the left side of the bent pipe, a permanent magnet synchronous motor mounted on the top of the motor support, a rotating disk disposed at the center of the right side inside the bent pipe, and several blades disposed on the outer side of the rotating disk, and further comprising:

[0007] An adjustment mechanism is located on the right side of the rotating disk. The mechanism includes a support rod fixedly connected to the inside of the bent pipe by screws. An electric push rod is fixedly connected to the right side of the support rod. The rotating disk has a hollow interior and contains a push plate. A limit ring is fixedly connected to the right side of the push plate. A limit convex shaft is fixedly connected to the output end of the electric push rod. Several push blocks are fixedly connected to the outer surface of the push plate. Each push block has an internal groove. A connecting shaft is fixedly connected to the bottom of the blades. A connecting block is fixedly connected to the bottom of the connecting shaft. A fixed shaft is fixedly connected to the bottom of the connecting block. By activating the electric push rod, the limit ring moves, which in turn moves the push plate along with the limit convex shaft, adjusting the position of the push plate. The push blocks on the outside of the push plate push the fixed shaft, causing the connecting block to rotate the connecting shaft on the fixed ring. The blades rotate with the connecting shaft, thus adjusting the blade angle to accommodate different air intake volumes. Adjusting the air intake ensures efficient airflow and eliminates the need for subsequent blade replacement.

[0008] The limiting convex shaft is located inside the limiting ring and connected by a bearing, and the diameter of the inner groove is slightly larger than that of the fixed shaft.

[0009] Furthermore, the fixed shaft is slidably connected inside the inner groove, and several fixed rings are fixedly connected inside the rotating disk. The fixed rings are arranged in a circumferential array around the rotating disk. The connecting shaft passes through the fixed rings and extends to the outside. When the rotating disk rotates, it drives the push plate to rotate together through the connecting shaft on the blade. The push plate then drives the limiting ring to rotate on the limiting convex shaft, so that the rotating disk can rotate smoothly and will not affect the movement of the push plate during the rotation. This method can both rotate the blade and adjust the blade angle during the rotation.

[0010] Furthermore, the connecting shaft is rotatably connected inside the fixed ring, and two protruding rings are fixedly connected to the outside of the connecting shaft. The two protruding rings on the connecting shaft are respectively set at both ends of the fixed ring, and a gap is left between the connecting block and the push block. The two protruding rings on the connecting shaft are used to cooperate with the fixed ring to keep the blade in a stable state and avoid shaking.

[0011] Furthermore, a bearing support is fixedly connected inside the bend, and the left side of the bearing support penetrates the bend and extends to the outside. A rotating rod is rotatably connected inside the bearing support via a bearing. Several brackets are fixedly connected to the outer surface of the bearing support, and the side of the brackets away from the bearing support is fixedly connected to the inner wall of the bend. The output end of the permanent magnet synchronous motor is fixedly connected to the left side of the rotating rod via a coupling. The fan is mounted on the equipment by means of a flange at the bottom of the bend, and the other end of the bend is connected to the pipeline via a flange. Different sizes of fans can be selected according to different application scenarios. Compared with traditional centrifugal fans, it does not require ground installation and does not require additional pipelines and bends. This not only reduces the energy consumption of the fan, but also facilitates the overall assembly and disassembly of the fan, making maintenance easier.

[0012] Furthermore, both ends of the rotating rod pass through the bearing support and extend to the outside. A mounting plate is fixedly connected to the right side of the rotating rod. The right side of the mounting plate contacts the left side of the rotating plate. A cross block is fixedly connected to the right side of the mounting plate. Several threaded holes are opened on the right side of the mounting plate. When the rotating plate is positioned and inserted into the cross block through the cross groove, the hole on the locking block is aligned with the threaded hole on the mounting plate, which facilitates subsequent bolt locking and fixing.

[0013] Furthermore, a shield is fixedly connected to the right side of the rotating disk, and the inner side of the shield is fixedly connected to the outer surface of the limiting ring. A cross groove is opened on the left side of the rotating disk, and several locking blocks are fixedly connected to the outer surface of the rotating disk. The bolts on the locking blocks are removed to release the rotating disk from the fixing. Then, the rotating disk is pulled to the right to disengage it from the cross block, which can quickly complete the disassembly and facilitate subsequent maintenance.

[0014] Furthermore, the rotating disk is positioned and inserted into the cross block on the mounting disk via a cross groove, the locking block corresponds to the threaded hole on the mounting disk, the locking block is internally connected to a bolt, and the locking block is fixedly connected to the mounting disk by the bolt.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model drives the limit ring to move by starting the electric push rod. The limit ring will drive the push plate to move together through the limit convex shaft. Adjust the position of the push plate. The push block on the outside of the push plate will push the fixed shaft. The connecting block will drive the connecting shaft to rotate on the fixed ring. At this time, the blade will rotate together with the connecting shaft, thereby adjusting the blade angle to meet different air intake volumes. By adjusting the air intake, the air intake efficiency can be ensured, and there is no need to replace the blades later.

[0017] (2) The fan of this utility model is installed on the equipment by means of the bottom of the bend pipe through the flange, and the other end of the bend pipe is connected to the pipeline through the flange. Different sizes of fans can be selected according to different application scenarios. Compared with the traditional centrifugal fan, it does not need to be installed on the ground, and it does not need to add pipes and bends. It can not only reduce the energy consumption of the fan, but also facilitate the overall assembly and disassembly of the fan, making it easy to maintain.

[0018] (3) When the rotating disk of this utility model rotates, it will drive the push plate to rotate together through the connecting shaft on the blade. The push plate will drive the limiting ring to rotate on the limiting convex shaft, so that the rotating disk can rotate smoothly and will not affect the movement of the push plate during the rotation. This method can not only make the blade rotate, but also adjust the angle of the blade during the rotation.

[0031] 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.

[0032] Please see Figures 1-8As shown, this utility model is a fan that increases the airflow inlet guidance direction, including a bend 1, a motor support 11 fixedly connected to the left side of the bend 1, a permanent magnet synchronous motor 12 mounted on the top of the motor support 11, a rotating disk 15 disposed at the center of the right side inside the bend 1, and a plurality of blades 14 disposed on the outer side of the rotating disk 15, and further including:

[0033] Adjustment mechanism 2 is located on the right side of the rotating disk 15. Adjustment mechanism 2 includes a support rod 21 fixedly connected to the inside of the bent pipe 1 by screws. An electric push rod 22 is fixedly connected to the right side of the support rod 21. The rotating disk 15 has a hollow interior and a push plate 23 is installed inside. A limit ring 24 is fixedly connected to the right side of the push plate 23. A limit cam 221 is fixedly connected to the output end of the electric push rod 22. Several push blocks 231 are fixedly connected to the outer surface of the push plate 23. An inner groove 232 is formed inside each push block 231. A connecting shaft 141 is fixedly connected to the bottom of the blade 14. A connecting block 142 is fixedly connected to the bottom of the connecting shaft 141. A fixed... Shaft 143; by starting the electric push rod 22, the limiting ring 24 is moved, and the limiting ring 24 will move the push plate 23 together through the limiting convex shaft 221. Adjusting the position of the push plate 23, the push block 231 on the outside of the push plate 23 will push the fixed shaft 143, and the connecting block 142 will drive the connecting shaft 141 to rotate on the fixed ring 152. At this time, the blade 14 will rotate with the connecting shaft 141, thereby adjusting the angle of the blade 14 to meet different air intake volumes. By adjusting the air intake, the air intake efficiency can be ensured, and the blade 14 does not need to be replaced later. The limiting convex shaft 221 is set inside the limiting ring 24 and connected by a bearing. The diameter of the inner groove 232 is slightly larger than that of the fixed shaft 143.

[0034] The fixed shaft 143 is slidably connected inside the inner groove 232. Several fixed rings 152 are fixedly connected inside the rotating disk 15. The fixed rings 152 are arranged in a circular array around the rotating disk 15. The connecting shaft 141 passes through the fixed rings 152 and extends to the outside. When the rotating disk 15 rotates, it will drive the push plate 23 to rotate together through the connecting shaft 141 on the blade 14. The push plate 23 will drive the limiting ring 24 to rotate on the limiting convex shaft 221, so that the rotating disk 15 can rotate smoothly and will not affect the movement of the push plate 23 during the rotation. This method can both rotate the blade 14 and adjust the angle of the blade 14 during the rotation.

[0035] The connecting shaft 141 is rotatably connected inside the fixed ring 152. Two protruding rings are fixedly connected to the outside of the connecting shaft 141. The two protruding rings on the connecting shaft 141 are respectively set at both ends of the fixed ring 152. A gap is left between the connecting block 142 and the push block 231. The two protruding rings on the connecting shaft 141 are used to cooperate with the fixed ring 152 to keep the blade 14 in a stable state and avoid shaking.

[0036] A bearing support 13 is fixedly connected inside the bend 1. The left side of the bearing support 13 passes through the bend 1 and extends to the outside. A rotating rod 131 is rotatably connected inside the bearing support 13 via a bearing. Several brackets 132 are fixedly connected to the outer surface of the bearing support 13. The side of the brackets 132 away from the bearing support 13 is fixedly connected to the inner wall of the bend 1. The output end of the permanent magnet synchronous motor 12 is fixedly connected to the left side of the rotating rod 131 via a coupling. The fan is mounted on the equipment by means of a flange at the bottom of the bend 1 and the other end of the bend 1 is connected to the pipeline via a flange. Different sizes of fans can be selected according to different application scenarios. Compared with traditional centrifugal fans, it does not require ground installation and does not require special addition of pipelines and bends. It can not only reduce the energy consumption of the fan, but also facilitate the overall assembly and disassembly of the fan, making maintenance easier.

[0037] Both ends of the rotating rod 131 pass through the bearing support 13 and extend to the outside. A mounting plate 133 is fixedly connected to the right side of the rotating rod 131. The right side of the mounting plate 133 contacts the left side of the rotating plate 15. A cross block 134 is fixedly connected to the right side of the mounting plate 133. Several threaded holes are opened on the right side of the mounting plate 133. When the rotating plate 15 is positioned and inserted into the cross block 134 through the cross groove 153, the hole on the locking block 154 is aligned with the threaded hole on the mounting plate 133, which facilitates subsequent bolt locking and fixing.

[0038] A shield 151 is fixedly connected to the right side of the rotating disk 15. The inner side of the shield 151 is fixedly connected to the outer surface of the limiting ring 24. A cross groove 153 is opened on the left side of the rotating disk 15. Several locking blocks 154 are fixedly connected to the outer surface of the rotating disk 15. The bolts on the locking blocks 154 are removed to release the rotating disk 15 from its fixation. Then the rotating disk 15 is pulled to the right to disengage it from the cross block 134, which can quickly complete the disassembly and facilitate subsequent maintenance.

[0039] The rotating disk 15 is positioned and inserted into the cross block 134 on the mounting disk 133 through the cross groove 153. The locking block 154 corresponds to the threaded hole on the mounting disk 133. The locking block 154 is inserted with a bolt and is fixedly connected to the mounting disk 133 by the bolt.

[0040] When a blower is needed in processes such as dust removal or smelting flue gas treatment, the bottom of the bend 1 is installed on the equipment via a flange, and the other end of the bend 1 is connected to the pipeline via a flange. By starting the permanent magnet synchronous motor 12, the rotating rod 131 is driven to rotate. The rotating rod 131 will drive the rotating disk 15 to rotate via the mounting plate 133. At this time, several blades 14 will rotate together, thereby achieving the effect of drawing in airflow. When the rotating disk 15 rotates, it will drive the push plate 23 to rotate together via the connecting shaft 141 on the blades 14. The push plate 23 will drive the limiting ring 24 to rotate on the limiting convex shaft 221, so that the rotating disk 15 can rotate smoothly. Therefore, compared with the traditional centrifugal blower, this method does not require ground installation and does not require special pipelines and bends. It can not only reduce the energy consumption of the blower, but also facilitate the overall assembly and disassembly of the blower, making maintenance easier. At the same time, the permanent magnet synchronous motor converts wind energy into electrical energy and feeds it directly back to the power grid of the plant area, achieving the function of power generation.

[0041] When different air volumes need to be adjusted, the electric push rod 22 is activated to move the limiting ring 24. The limiting ring 24 will then move the push plate 23 together through the limiting convex shaft 221 to adjust the position of the push plate 23. When the push plate 23 moves, it will push the fixed shaft 143 on the connecting block 142 through the outer push block 231. Since the fixed shaft 143 slides in the inner groove 232, the push block 231 can smoothly push the fixed shaft 143. When the fixed shaft 143 is pushed, it will drive the connecting shaft 141 to rotate on the fixed ring 152 through the connecting block 142. At this time, the blade 14 will rotate together with the connecting shaft 141, thereby adjusting the angle of the blade 14. By adjusting the angle of the blade 14, different air intake volumes can be met. By adjusting the air intake, the air extraction efficiency can be ensured, and the blade 14 does not need to be replaced later. The shield 151 on the rotating plate 15 shields the internal parts of the rotating plate 15 to reduce dust from entering the interior.

[0042] When the rotating disk 15 needs to be disassembled for maintenance or replacement, remove the screws connecting the support rod 21 to the bend 1 to release the support rod 21. Then remove the bolts on the locking block 154 to release the rotating disk 15. Then pull the rotating disk 15 to the right to disengage it from the cross block 134. This method facilitates subsequent maintenance. When the rotating disk 15 needs to be installed, insert the rotating disk 15 into the cross block 134 through the cross groove 153. Then align the hole on the locking block 154 with the threaded hole on the mounting plate 133. Then install the bolts to fix the rotating disk 15 on the mounting plate 133. Finally, fix the support rod 21 to the inner wall of the bend 1 with screws to complete the installation.

[0043] It should be noted that the control of the permanent magnet synchronous motor 12 and the electric push rod 22 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be set using existing technologies, such as PLC, and can be controlled intelligently by AI. At the same time, it can be combined with various sensor controls as needed. Based on real-time monitoring of flue gas temperature, dust concentration and other data, the fan speed is dynamically adjusted through neural network algorithms to achieve optimal air pressure matching.
