Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing equipment technology, specifically to a replaceable blade connection mechanism for a wear-resistant atomizing wheel. Background Technology
[0002] The atomizing wheel is driven by a motor to rotate at high speed. It uses the centrifugal force generated by the blades on the material (such as slurry containing particles or high-viscosity fluid) to break it into fine droplets, thus completing the atomization process. As a key component that directly contacts the material, the stability of the connection between the blades and the wheel, their wear resistance, and ease of maintenance directly determine the atomization efficiency, equipment lifespan, and operating costs.
[0003] The connection between the atomizing wheel blades and the wheel disc is usually a simple, detachable bolt connection. When the atomizing wheel rotates at high speed, it generates strong centrifugal force and vibration. Long-term operation can easily cause the bolts to loosen, resulting in radial displacement or circumferential movement of the blades. This not only damages the atomization effect but may also cause the blades to collide with the equipment housing, resulting in equipment damage or even safety accidents, making it difficult to ensure the continuous and stable operation of the equipment. Utility Model Content

To solve these technical problems, this invention is achieved through the following technical solution: This utility model relates to a replaceable blade connection mechanism for a wear-resistant atomizing wheel, comprising: A connecting component, the connecting component including blades and a support disk, the blades being disposed on the outer surface of the support disk; The replacement components include a support rod, a mounting base, a rotating shaft, a fixed plate, an inner groove, a limiting block, and a spring. The support plate is embedded in the outer surface of the rotating shaft, which is located in the middle of one end of the outer surface of the atomizing wheel. The fixed plate is located at the outer end of the rotating shaft, and the support rod is located at the outer end of the fixed plate. An inner groove is formed inside the fixed plate, and a spring is fixed inside the inner groove. The limiting block is located at the outer end of the spring and blocks the outer end of the support plate. The mounting base is sleeved on the outside of the support rod, and one end of its outer surface is in contact with the fixed plate.
[0005] Furthermore, the limiting block has a positioning hole inside, and a positioning rod is fixed to one end of the outer surface of the mounting base. The positioning rod is inserted into and connected to the inside of the positioning hole.
[0006] Furthermore, an outer ring is fitted onto one end of the outer surface of the support rod, and a sliding groove is formed inside the outer ring. A slider is provided inside the mounting plate, and the slider is slidably connected inside the sliding groove.

[0015] 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.
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0017] Please see Figure 1-6 As shown, this utility model is a replaceable blade 11 connecting mechanism for a wear-resistant atomizing wheel, comprising: A connecting component, the connecting component including a blade 11 and a support disk 12, the blade 11 being disposed on the outer surface of the support disk 12; The replacement components include a support rod 21, a mounting base 22, a rotating shaft 23, a fixed plate 24, an inner groove 26, a limiting block 27, and a spring 28. The support plate 12 is embedded in the outer surface of the rotating shaft 23, which is located in the middle of one end of the outer surface of the atomizing wheel. The fixed plate 24 is located at the outer end of the rotating shaft 23, and the support rod 21 is located at the outer end of the fixed plate 24. The fixed plate 24 has an inner groove 26 inside, and the spring 28 is fixed inside the inner groove 26. The limiting block 27 is located at the outer end of the spring 28 and blocks the outer end of the support plate 12. The mounting base 22 is sleeved on the outside of the support rod 21, and one end of its outer surface is in contact with the fixed plate 24. The system employs a triple protection mechanism to prevent loosening: First, after the support plate 12 is inlaid, the spring 28 rebounds and drives the limit block 27 to mechanically block the outer end of the support plate 12, directly limiting its radial displacement. Second, the positioning rod 25 cooperates with the positioning hole 29 to lock the circumferential position of the limit block 27, preventing it from shifting during high-speed rotation. Third, the locking ring 36 is rigidly connected to the support rod 21 through threads, tightly fitting the outer end of the mounting base 22 to form an axial tightening force. The triple protection works synergistically to effectively resist the centrifugal force and vibration generated by the high-speed rotation of the atomizing wheel, completely avoiding safety hazards such as blade 11 displacement and collision caused by bolt loosening, and ensuring continuous and stable operation of the equipment.
[0018] The limiting block 27 has a positioning hole 29 inside, and a positioning rod 25 is fixed to one end of the outer surface of the mounting base 22. The positioning rod 25 is inserted into and connected to the inside of the positioning hole 29. The positioning rod 25 passes through the pre-set positioning hole 29 of the limiting block 27, directly restricting the radial extension and retraction of the limiting block 27 (preventing the limiting block 27 from retracting into the inner groove 26 due to vibration), thereby achieving rigid locking of the position of the limiting block 27 and further strengthening the limiting effect of the support plate 12.
[0019] One end of the outer surface of the support rod 21 is fitted with an outer ring 31, and a groove 32 is provided inside the outer ring 31. A slider 33 is provided inside the mounting plate, and the slider 33 is slidably connected inside the groove 32. The cooperation between the slider 33 and the groove 32 ensures that the mounting base 22 can only translate along the axial direction of the support rod 21, avoiding circumferential deflection.
[0020] The inner surface of the inner groove 26 is provided with a guide groove 34, and the outer surface of the limiting block 27 is provided with a guide block 35, which is slidably connected to the inside of the guide groove 34. The cooperation between the guide block 35 and the guide groove 34 ensures that the limit block 27 can only extend and retract in a straight line, avoiding offset and jamming.
[0021] A locking ring 36 is threaded onto the outer surface of the support rod 21, and the locking ring 36 is fastened to the other end of the outer surface of the mounting base 22. The threaded connection of the locking ring 36 generates anti-loosening friction to resist the vibration and impact generated by the high-speed rotation of the atomizing wheel and prevent gaps between components.
[0022] Working principle: The support plate 12 serves as the bearing base for the blade 11, and its connection with the rotating shaft 23 is the primary step in fixing the blade 11. During installation, the support plate 12 is axially embedded along the rotating shaft 23. When the support plate 12 moves to the position of the fixed plate 24, the edge of the support plate 12 contacts the limiting block 27 on the fixed plate 24 and generates a compressive force. At this time, the limiting block 27 slides radially within the pre-set guide groove 34 of the fixed plate 24 through the guide block 35 at the bottom, while simultaneously compressing the spring 28 inside the limiting block 27, causing the limiting block 27 to retract into the inner groove 26 of the fixed plate 24. When the support plate 12 is fully embedded in the pre-set position of the rotating shaft 23, the compressive force between the support plate 12 and the limiting block 27 disappears, and the spring 28 rebounds under its own elastic potential energy, pushing the limiting block 27 back along the guide groove 34. Its outer end extends out of the inner groove 26 and blocks the outer end face of the support plate 12, forming a radial mechanical limit, directly restricting the movement. The support plate 12 is displaced along the axial direction of the rotating shaft 23, completing the initial locking between the support plate 12 and the rotating shaft 23. Next, the mounting base 22 is sleeved on the support rod 21 on the outside of the fixed plate 24. The slider 33 on the inner side of the mounting base 22 slides along the groove 32 inside the outer ring 31 until the mounting base 22 and the end face of the fixed plate 24 are tightly fitted. At this time, the positioning rod 25 on the mounting base 22 is axially aligned with the positioning hole 29 on the limiting block 27. After the positioning rod 25 is inserted into the positioning hole 29, the positioning rod 25 passes through the preset through hole of the limiting block 27, directly restricting the radial extension and retraction of the limiting block 27. Finally, the internal thread of the locking ring 36 engages with the external thread of the support rod 21. The locking ring 36 is rotated to move along the axial direction of the support rod 21 until it is tightly fitted with the outer end face of the mounting base 22 and a continuous axial pressure is applied.
[0023] During disassembly, rotate the locking ring 36 in the opposite direction to separate it from the mounting base 22, release the axial pressure, pull out the positioning rod 25, release the locking constraint on the limiting block 27, slide the mounting base 22 along the slide groove 32 of the support rod 21 to remove it, exposing the support plate 12 and the limiting block 27, press the limiting block 27 inward to release the radial obstruction on the support plate 12, and then the support plate 12 can be pulled out from the rotating shaft 23 to complete the disassembly of the blade 11.
[0024] This step, through a coordinated operation mechanism of mechanical limiting, precise guidance, and multi-level locking, achieves a reliable connection and convenient assembly / disassembly between the blade 11 and the atomizing wheel rotation shaft 23.
[0025] Please see Figure 1-6 As shown, this embodiment, based on the above embodiment, further includes: The mounting component includes a support frame 41, a socket 42, and a rod 43. The support frame 41 is fixed to the outer surface of the support plate 12, the bottom of the blade 11 is embedded in the inside of the support frame 41, the socket 42 is opened inside the support frame 41 and the blade 11, and the rod 43 is inserted and connected inside the socket 42. The radial displacement of the blade 11 is restricted by the side wall of the support frame 41, so that the blade 11 is initially positioned at the preset installation angle. The insertion rod 43 and the insertion hole 42 adopt an intermediate fit, which not only ensures accurate insertion without wobbling, but also avoids the difficulty of disassembly and assembly caused by interference fit. At this time, the insertion rod 43 bears the circumferential torque generated when the blade 11 rotates, preventing the blade 11 from moving axially along the support frame 41.
[0026] The outer surface of the insertion rod 43 is threaded with a fastening ring 44, which is fastened to both sides of the support frame 41. The clamping force of the fastening ring 44 is transmitted through the insertion rod 43 to the contact surface between the bottom of the blade 11 and the support frame 41. While eliminating gaps, the self-locking characteristic of the threaded connection is used to resist the vibration and impact generated by the high-speed rotation of the atomizing wheel, ensuring that the insertion rod 43 does not loosen and the blade 11 does not shift.
[0027] Working principle: When installing a single blade 11, first insert the bottom of the blade 11 along the inner side of the support frame 41, and then insert the rod 43 horizontally along the rod 43 hole on the side wall of the support frame 41 until the rod 43 passes through the insertion hole 42 at the bottom of the blade 11, forming a transverse rigid connection. Finally, the internal thread of the fastening ring 44 engages with the external thread of the rod 43, and the fastening ring 44 is rotated to move it axially along the rod 43 until it fits tightly against the outer wall of the support frame 41 and a continuous clamping force is applied.
[0028] This step, through a combination of positioning and threaded locking, enables the rapid and independent assembly and disassembly of individual blades 11, while ensuring connection reliability under high-speed rotation through multiple force constraints, effectively solving the problems of high maintenance costs and low assembly and disassembly efficiency of traditional integral connections.
