Description

Technical Field

[0001] This invention relates to a micro-mist humidification nozzle replacement mechanism, belonging to the field of nozzle replacement technology. Background Technology

[0002] Micro-mist humidification technology pressurizes water to 50-100 bar and atomizes it into ultra-fine droplets of 3-15 micrometers through precision nozzles, achieving efficient humidification, cooling, or dust removal. With water-saving efficiency exceeding 90% and low energy consumption, it has gradually replaced traditional electric heating and centrifugal humidification equipment, and is widely used in new energy power batteries, semiconductor packaging, precision optical manufacturing, large-scale residential buildings, and high-end homestays. The nozzle, as the core component of the micro-mist humidification system, directly determines the humidification quality through its atomization effect. However, due to water impurities and scale buildup, the nozzle is prone to clogging and wear, requiring regular disassembly and replacement to ensure normal system operation.

[0003] As the core component of a micro-mist humidification system, the nozzle's atomization effect directly determines the humidification quality and control effect of the entire system. However, in actual use, due to factors such as water impurities and scale buildup after long-term use, the nozzle is prone to clogging, wear, and other malfunctions. It needs to be disassembled and replaced regularly to ensure the stable and normal operation of the micro-mist humidification system.

[0004] Currently, most micro-mist humidification nozzles on the market are fixed to the liquid supply pipeline using a threaded connection. This connection method requires the use of special tools such as wrenches and pliers when replacing the nozzles, which is cumbersome and requires a large operating space. In a confined installation space, it is difficult to use the tools smoothly, which not only leads to low nozzle replacement efficiency and significantly increases equipment downtime for maintenance, but also, in industrial settings, frequent and inefficient nozzle replacement operations for densely arranged multi-nozzle micro-mist humidification systems will significantly increase the equipment maintenance costs for enterprises, thus hindering the application and promotion of micro-mist humidification technology. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a micro-mist humidification nozzle replacement mechanism, thereby resolving the issues raised in the background section.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A micro-mist humidification nozzle replacement mechanism includes a housing, a nozzle mounting bracket fixedly installed on the top of the housing, a mounting plate disposed inside the housing, and a maintenance port opened at the bottom of the housing; an air inlet is installed at one end of the housing and an air outlet is installed at the other end of the housing; a replacement component is disposed on one side of the mounting plate and an up-and-down adjustment component is disposed on the other side of the mounting plate.

[0008] The replacement component includes a cylinder, an electric chuck, and an internally threaded tube. Multiple internally threaded tubes are connected and installed on the nozzle mounting bracket. Multiple cylinders are rotatably installed on the mounting plate corresponding to the positions of the internally threaded tubes. An electric chuck is fixedly installed on the end face of each cylinder near the internally threaded tube. The electric chuck is used to hold the micro-mist nozzle. The outer wall of each micro-mist nozzle near the internally threaded tube has a threaded section, which is used to be threaded into the internally threaded tube.

[0009] Preferably, the up-and-down adjustment assembly includes a motor, a corrosion-resistant lead screw, and a threaded block; the corrosion-resistant lead screw is vertically rotatably installed inside the housing, and a threaded block is threaded onto the corrosion-resistant lead screw; an electric push rod is horizontally installed on the outer wall of the threaded block, and an installation plate is installed at the output end of the electric push rod; the motor is fixedly installed on the top wall of the housing, and the output end of the motor is connected to the corrosion-resistant lead screw for driving the corrosion-resistant lead screw to rotate.

[0010] Preferably, multiple sets of mounting seats are symmetrically installed on the side of the mounting plate near the electric push rod, and a drive rod is vertically rotatably installed between each set of mounting seats. A worm gear is fixedly sleeved on each drive rod, and a turbine is meshed on each worm gear. Multiple turbines are fixedly installed on the outer wall of their corresponding cylinders.

[0011] Preferably, a gear is fixedly installed on the top of each drive rod, and a rack is adapted to mesh with each gear. Each rack is fixedly installed on the top wall of the housing via a connecting bracket.

[0012] Preferably, the threaded block has horizontally mounted extension plates on both its front and rear outer walls, and vertical plates are vertically mounted on the ends of the extension plates away from the threaded block. Guide posts slide horizontally through the upper and lower ends of the vertical plates, and the ends of the guide posts away from the vertical plates are fixedly mounted on the outer wall of the mounting plate.

[0013] Preferably, guide rods are vertically installed on both the front and rear walls of the box, and the guide rods slide through their corresponding extension plates.

[0014] Preferably, a maintenance door is hingedly installed inside the maintenance opening, and the maintenance door is used to close and seal the maintenance opening.

[0015] Preferably, a rectangular partition is vertically installed at the bottom of the housing, and a sewage collection tank is installed on the top wall of the rectangular partition. The sewage collection tank is used to collect water that falls during the replacement of the micro-mist nozzle.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. By replacing components and adjusting the components up and down in a coordinated manner, the traditional manual operation method using wrenches, pliers, and other special tools is replaced. It eliminates the need for manual operation skills, significantly lowers the operational threshold for nozzle replacement, and breaks through the limitations of limited installation space on tool application. It effectively solves the problems of cumbersome operation and low efficiency of traditional replacement methods.

[0018] 2. Simultaneous replacement of multiple nozzles: The internal threaded tubes on the nozzle mounting bracket are arranged one-to-one with the cylinders and electric clamps on the mounting plate, which can simultaneously complete the clamping, loosening and tightening of multiple micro-mist nozzles. Compared with the traditional method of replacing one nozzle at a time, this greatly improves the replacement efficiency, significantly reduces equipment downtime for maintenance, and reduces maintenance downtime losses of multi-nozzle micro-mist humidification systems in industrial settings.

[0019] 3. The transmission and adjustment structure is precise and stable. It adopts an up-and-down adjustment structure of motor and corrosion-resistant lead screw, combined with guide rod and extension plate guide limit, to achieve precise control of the vertical position of the replacement component. When the electric push rod drives the mounting plate to move horizontally, the sliding cooperation between the guide column and the vertical plate ensures the linearity of the movement trajectory. Combined with the deceleration and torque increase of worm gear and turbine and self-locking transmission, the clamping and threaded disassembly and assembly of the micro-mist nozzle are more precise, and the connection stability after installation is higher, avoiding errors and loosening problems caused by manual operation.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-6 The present invention provides a technical solution: a micro-mist humidification nozzle replacement mechanism, comprising a housing 1, a nozzle mounting bracket 6 fixedly installed on the top of the housing 1, a mounting plate 14 disposed inside the housing 1, and a maintenance port 4 opened at the bottom of the housing 1; an air inlet 2 is installed at one end of the housing 1, and an air outlet 3 is installed at the other end of the housing 1, characterized in that: a replacement component is disposed on one side of the mounting plate 14, and an up-and-down adjustment component is disposed on the other side of the mounting plate 14.

[0030] The replacement components include a cylinder 22, an electric chuck 23, and an internally threaded tube 25. Multiple internally threaded tubes 25 are connected and installed on the nozzle mounting bracket 6. Multiple cylinders 22 are rotatably installed on the mounting plate 14 corresponding to the positions of the internally threaded tubes 25. An electric chuck 23 is fixedly installed on the end face of each cylinder 22 near the internally threaded tube 25. The electric chuck 23 is used to hold the micro-mist nozzle 24. The outer wall of each micro-mist nozzle 24 near the internally threaded tube 25 has a threaded section 16, which is used to be threaded into the internally threaded tube 25.

[0031] In an embodiment of the present invention, the internally threaded tube 25 on the nozzle mounting bracket 6 provides a threaded connection base for the micro-mist nozzle 24. When the nozzle needs to be replaced, the cylinder 22 on the mounting plate 14 moves with the adjustment component to the position of the corresponding internally threaded tube 25. The electric chuck 23 first accurately clamps the micro-mist nozzle 24, and then the cylinder 22 rotates, driving the electric chuck 23 and the clamped micro-mist nozzle 24 to rotate synchronously. By utilizing the threaded section 16 on the outer wall of the micro-mist nozzle 24 and the threaded engagement of the internally threaded tube 25, the nozzle can be unscrewed or screwed in for installation.

[0032] The electric chuck 23 replaces manual hand tools for holding the nozzles, and in conjunction with the rotational transmission of the cylinder 22, the installation and removal of the nozzle threads are automated, eliminating the need for special tools such as wrenches and pliers, thus overcoming the limitations of tool operation in confined spaces. Multiple cylinders 22 are arranged one-to-one with the internal threaded tube 25, enabling the simultaneous replacement of multiple nozzles, greatly improving nozzle replacement efficiency and reducing equipment downtime for maintenance.

[0033] Please see Figure 4 The up-down adjustment assembly includes a motor 7, a corrosion-resistant lead screw 8, and a threaded block 9. The corrosion-resistant lead screw 8 is vertically rotatably installed inside the housing 1, and the threaded block 9 is threaded on the corrosion-resistant lead screw 8. An electric push rod 13 is horizontally installed on the outer wall of the threaded block 9, and an installation plate 14 is installed on the output end of the electric push rod 13. The motor 7 is fixedly installed on the top wall of the housing 1, and the output end of the motor 7 is connected to the corrosion-resistant lead screw 8 for driving the corrosion-resistant lead screw 8 to rotate.

[0034] In an embodiment of the present invention, after the motor 7 starts, it outputs a torque, which is directly transmitted to the vertically arranged corrosion-resistant lead screw 8, causing the corrosion-resistant lead screw 8 to rotate around its own axis; the rotation of the corrosion-resistant lead screw 8 is converted into the vertical linear motion of the threaded block 9 through the threaded engagement, and the movement of the threaded block 9 synchronously drives the electric push rod 13 and the mounting plate 14 connected to the electric push rod 13 to perform overall vertical lifting and lowering, thereby realizing the adjustment of the up and down position of the replacement component on the mounting plate 14.

[0035] The transmission system employs a motor 7 and a corrosion-resistant lead screw 8 to achieve precise vertical position control of the replacement components. It features high transmission accuracy and strong operational stability, and can adapt to the replacement needs of nozzles arranged at different heights. The corrosion-resistant lead screw 8 is suitable for the humid working environment of humidification equipment, extending the service life of the adjustment components. The overall transmission structure is compact, occupying little space within the housing 1, and is compatible with the overall layout design of the equipment. The electric push rod 13 can further enable the horizontal extension and retraction of the mounting plate 14, allowing the replacement components to be precisely aligned with the nozzle position, improving the accuracy of disassembly and assembly.

[0036] Please see Figure 5 Multiple sets of mounting seats 17 are symmetrically installed on the side of the mounting plate 14 near the electric push rod 13, and a drive rod 18 is vertically rotatably installed between each set of mounting seats 17. A worm gear 19 is fixedly sleeved on each drive rod 18, and a turbine 20 is meshed on each worm gear 19. Multiple turbines 20 are fixedly installed on the outer wall of the corresponding cylinder 22.

[0037] In an embodiment of the present invention, the drive rod 18 rotates around its own vertical axis under the drive of an external force, driving the worm gear 19 fixedly sleeved on it to rotate synchronously; the worm gear 19 transmits power to the turbine 20 through tooth meshing, converting its own vertical rotational motion into the horizontal rotational motion of the turbine 20; the turbine 20 is fixedly connected to the cylinder 22, thereby driving the cylinder 22 and the electric chuck 23 at the end to rotate synchronously, providing rotational power for the threaded assembly and disassembly of the nozzle.

[0038] The meshing transmission of the worm gear 19 and turbine 20 has self-locking properties, which can effectively prevent the cylinder 22 from rotating randomly after the nozzle is disassembled and assembled, ensuring the connection stability after the nozzle is installed. This transmission structure can achieve smooth power transmission and has a certain speed reduction and torque increase effect, providing sufficient rotational torque for nozzle disassembly and assembly, and easily completing the tightening and loosening of threads. Multiple sets of worm gear 19 and turbine 20 correspond one-to-one with cylinder 22, which can realize independent power control for the disassembly and assembly of multiple nozzles, adapting to the replacement needs of different nozzles.

[0039] Please see Figure 4 Each drive rod 18 has a gear 21 fixedly installed on its top, and each gear 21 is fitted with a rack 27. Each rack 27 is fixedly installed on the inner top wall of the housing 1 through a connecting bracket 26.

[0040] In an embodiment of the present invention, the gear 21 at the top of the drive rod 18 and the rack 27 fixed to the top wall of the housing 1 by the connecting bracket 26 are in a meshing relationship. When the electric push rod 13 drives the mounting plate 14 to move horizontally and reciprocally, the mounting plate 14 will drive the drive rod 18 and the gear 21 to move horizontally synchronously. Under the meshing action with the fixed rack 27, the gear 21 converts its horizontal linear motion into vertical rotational motion around the axis of the drive rod 18, thereby driving the drive rod 18 to rotate synchronously, providing the original power for the transmission of the worm gear 19 and the turbine 20, and finally transmitting it to the cylinder 22 and the electric chuck 23.

[0041] The transmission design of the gear 21 and rack 27 eliminates the need for an independent rotary drive motor 7 for the drive rod 18. Power is directly supplied by the horizontal movement of the mounting plate 14, significantly simplifying the transmission structure, reducing the number of electrical components, and lowering manufacturing costs and the probability of failure. The high meshing precision of the gear 21 and rack 27 accurately converts the horizontal displacement of the mounting plate 14 into the rotation angle of the drive rod 18, making the loosening and tightening stroke of the micro-mist nozzle 24 controllable and preventing issues such as stripping of the thread section 16 or improper installation caused by excessive rotation. Simultaneously, the high power transmission efficiency of the gear 21 and rack 27, combined with the reduction and torque amplification of the worm gear 19 and worm 20, meets the torque requirements for the installation and removal of the micro-mist nozzle 24. Furthermore, this transmission method is linked to the horizontal movement of the mounting plate 14, achieving automated connection of the installation and removal actions without additional manual operation, thus improving the overall continuity of the replacement process.

[0042] Please see Figure 4 The threaded block 9 has horizontal extension plates 10 installed on both the front and rear walls. The ends of the extension plates 10 away from the threaded block 9 are vertically installed with vertical plates 11. The upper and lower ends of the vertical plates 11 are horizontally slidably traversed by guide posts 15. The ends of the guide posts 15 away from the vertical plates 11 are fixedly installed on the outer wall of the mounting plate 14.

[0043] In an embodiment of the present invention, when the electric push rod 13 drives the mounting plate 14 to move horizontally, the guide post 15 on the outer wall of the mounting plate 14 will slide horizontally synchronously along the through hole on the vertical plate 11. The vertical plate 11 is fixedly connected to the threaded block 9 through the extension plate 10, forming a guide and limiting structure for the horizontal movement of the mounting plate 14, so that the mounting plate 14 always moves in a parallel state with the nozzle mounting bracket 6.

[0044] The sliding fit between the guide post 15 and the vertical plate 11 provides precise trajectory constraints for the horizontal movement of the mounting plate 14, effectively preventing the mounting plate 14 from tilting or wobbling during movement. This ensures that the electric chuck 23 can accurately engage with the clamping position of the micro-mist nozzle 24, improving the accuracy of clamping and disassembling the micro-mist nozzle 24. At the same time, this structure provides horizontal support for the mounting plate 14, dispersing the radial force on the output end of the electric push rod 13. This prevents the electric push rod 13 from experiencing piston rod bending or seal wear due to long-term uneven loading, extending the service life of the electric push rod 13. The symmetrical arrangement of multiple guide posts 15 on the mounting plate 14 makes the force on the mounting plate 14 more uniform and the movement process more stable. This ensures that multiple electric chucks 23 can simultaneously and accurately engage with the corresponding micro-mist nozzles 24, ensuring the smooth replacement of multiple nozzles simultaneously. Furthermore, the sliding fit structure has low frictional resistance, which does not affect the movement efficiency of the mounting plate 14, balancing the stability and smoothness of the movement.

[0045] Please see Figure 4 Guide rods 12 are vertically installed on both the front and rear walls of the box 1, and the guide rods 12 slide through their corresponding extension plates 10.

[0046] In an embodiment of the present invention, when the motor 7 drives the corrosion-resistant lead screw 8 to rotate and drives the threaded block 9 to make vertical lifting and lowering movements, the extension plate 10 on the threaded block 9 moves synchronously with the threaded block 9. The extension plate 10 slides along the guide rod 12 installed vertically inside the housing 1. The guide rod 12 provides trajectory limitation for the vertical movement of the extension plate 10 and the threaded block 9.

[0047] The guide rod 12 precisely guides the vertical lifting and lowering of the threaded block 9, effectively preventing the threaded block 9 from rotating circumferentially with the rotation of the corrosion-resistant lead screw 8. This ensures that the rotational motion of the lead screw is completely converted into the vertical linear motion of the threaded block 9, improving the transmission efficiency and position control accuracy of the up-and-down adjustment assembly. The sliding fit between the extension plate 10 and the guide rod 12 provides additional vertical support for the threaded block 9, dispersing the radial force on the corrosion-resistant lead screw 8, reducing the bending deformation of the lead screw, and extending the service life of the lead screw 8 and the motor 7. The symmetrical arrangement of multiple guide rods 12 makes the vertical movement of the threaded block 9 more stable, preventing tilting during the lifting and lowering process when replacing components.

[0048] Please see Figure 2 A maintenance door 5 is hinged inside the maintenance port 4, and the maintenance door 5 is used to close and seal the maintenance port 4.

[0049] In an embodiment of the present invention, the maintenance door 5 and the maintenance port 4 are hinged. When manual intervention or maintenance is required for the nozzles or replacement components inside the housing 1, the maintenance door 5 can be turned outward to open the maintenance port 4. After maintenance is completed, the maintenance door 5 can be turned in the opposite direction to close and seal the maintenance port 4. Buckles and seals can be added to improve the sealing performance of the closure.

[0050] The design of maintenance port 4 and hinged maintenance door 5 provides a convenient operating channel for manual maintenance of equipment inside the housing 1, removal of discarded nozzles, and placement of new nozzles, without the need to disassemble the overall structure of housing 1, reducing the difficulty of manual operation; after maintenance door 5 is closed, it can effectively seal maintenance port 4, preventing water mist and moisture inside housing 1 from escaping outward, while also preventing external dust and impurities from entering the interior of housing 1, contaminating the humidification system or affecting the normal operation of components; maintenance door 5 has a simple structure and is easy to operate, adapting to the needs of rapid maintenance in industrial scenarios.

[0051] Please see Figure 1 A rectangular partition 28 is vertically installed at the bottom of the box 1, and a sewage collection tank 29 is installed on the top wall of the rectangular partition 28. The sewage collection tank 29 is used to collect the water that falls during the replacement of the micro-mist nozzle 24.

[0052] In an embodiment of the present invention, during the nozzle replacement process, the water remaining in the micro-mist nozzle 24 and the internal threaded tube 25 will fall downwards due to gravity. The rectangular partition 28 at the bottom of the box 1 blocks and guides the falling sewage, so that the surface of the rectangular partition 28 collects into the sewage collection tank 29 at the top, thereby realizing the centralized collection of sewage.

[0053] Wastewater collected in the wastewater collection tank 29 is collected during nozzle replacement to prevent it from flowing onto electrical and transmission components such as the motor 7, corrosion-resistant lead screw 8, worm gear 19, and turbine 20 inside the housing 1. This prevents short circuits, corrosion, and jamming caused by water ingress, extending the overall service life of the equipment. The guide design of the rectangular partition 28 improves the efficiency of wastewater collection, ensuring that wastewater collects without dead corners, keeping the bottom of the housing 1 dry and clean, and reducing the frequency of equipment maintenance. The wastewater collection tank 29 is detachable, facilitating wastewater dumping and tank cleaning, and is easy to operate.

[0054] The workflow of this embodiment is as follows:

[0055] In its original state, the mounting plate 14 is located at the bottom of the housing 1, and the maintenance door 5 is in the closed and sealed position.

[0056] When it is necessary to disassemble and replace the micro-mist nozzle 24 in the internal threaded tube 25 on the nozzle mounting bracket 6, an operation command is first sent through the external controller to control the motor 7 to start and rotate forward. The output shaft of the motor 7 drives the corrosion-resistant lead screw 8 to rotate synchronously. Utilizing the threaded engagement principle, the rotating corrosion-resistant lead screw 8 drives the threaded block 9 to move vertically upward along the guide rod 12. The threaded block 9 synchronously drives the electric push rod 13 and the mounting plate 14 to move upward as a whole until the electric chuck 23 on the mounting plate 14 is at the same horizontal height as the micro-mist nozzle 24 to be replaced, and then the motor 7 stops running.

[0057] Then, the electric push rod 13 is activated. The output end of the electric push rod 13 pushes the mounting plate 14 to move horizontally towards the nozzle mounting bracket 6. The guide post 15 on the outer wall of the mounting plate 14 slides smoothly along the through hole on the vertical plate 11 to guide the horizontal movement of the mounting plate 14. When each electric clamp 23 has moved precisely to the clamping position of the corresponding micro-mist nozzle 24, the electric push rod 13 stops extending and retracting, and all electric clamps 23 are immediately activated to firmly clamp the corresponding micro-mist nozzle 24.

[0058] After clamping is completed, the electric push rod 13 is activated again and retracted, driving the mounting plate 14 and the electric chuck 23 to move horizontally towards the corrosion-resistant lead screw 8. During this process, the gear 21 on the mounting plate 14 meshes with the rack 27 in the housing 1. The gear 21 rotates as the mounting plate 14 moves, thereby driving the drive rod 18 to rotate synchronously. The rotating drive rod 18 drives the worm gear 19 to rotate. The worm gear 19 transmits power to the turbine 20 through tooth meshing, converting the vertical rotational motion into horizontal rotational motion. The turbine 20 drives the cylinder 22 and the electric chuck 23 at the end to rotate synchronously. The electric chuck 23 drives the clamped micro-mist nozzle 24 to rotate. By utilizing the threaded engagement between the threaded section 16 and the internal threaded tube 25, the micro-mist nozzle 24 can be loosened and disassembled.

[0059] Once the micro-mist nozzle 24 is fully unscrewed from the internal threaded tube 25, the electric push rod 13 stops retracting. Then, the control motor 7 reverses, driving the corrosion-resistant lead screw 8 to rotate in the opposite direction. This causes the threaded block 9 to move the mounting plate 14 and the disassembled micro-mist nozzle 24 vertically downwards along the guide rod 12 until the mounting plate 14 moves to the operating height near the maintenance port 4, at which point the motor 7 stops operating.

[0060] At this point, manually rotate the maintenance door 5 outward to open the maintenance port 4, remove the discarded micro-mist nozzle 24 from the electric chuck 23, and then accurately place the new micro-mist nozzle 24 into each electric chuck 23 in sequence. Start the electric chuck 23 to securely clamp the new micro-mist nozzle 24, and then close the maintenance door 5.

[0061] Then, reverse the entire process described above: first, control the motor 7 to rotate forward, moving the mounting plate 14 to the corresponding height. Then, start the electric push rod 13 to push the mounting plate 14 towards the nozzle mounting bracket 6. During this process, the gear 21 meshes with the rack 27, causing the drive rod 18, worm gear 19, and turbine 20 to rotate in the opposite direction. This causes the electric chuck 23 to rotate the new micro-mist nozzle 24 in the opposite direction, screwing the threaded section 16 of the micro-mist nozzle 24 into the internal threaded tube 25 and tightening it, thus completing the installation of the new micro-mist nozzle 24.

[0062] After installation, the electric clamp 23 releases its grip on the mist nozzle 24, the electric push rod 13 retracts to reset the mounting plate 14, and the motor 7 reverses to move the mounting plate 14 down to its original position at the bottom of the housing 1, thus completing the entire replacement process of the mist nozzle 24.

[0063] During the entire replacement process, the residual sewage in the micro-mist nozzle 24 and the internal threaded pipe 25 will fall due to gravity and be guided by the rectangular baffle 28, eventually converging into the sewage collection tank 29 for centralized collection. It will be cleaned up uniformly after the replacement operation is completed.
