Description

Technical Field

[0001] The present invention belongs to the technical field of air cooling, and specifically relates to a composite air cooling and rectifying device. Background Art

[0002] In the current field of air treatment equipment, many drawbacks have emerged in traditional air cooling and rectifying technologies.

[0003] In terms of air cooling, traditional cooling plates mostly adopt a single self-cooling method, relying only on the heat conduction performance of the cooling plate itself to dissipate heat. This cooling method is inefficient and cannot quickly and fully exchange heat with the flowing air, resulting in poor air cooling effect; in addition, as a key component in the air cooling process, the honeycomb plate group is prone to being blocked by impurities in the internal honeycomb holes after long-term use, affecting the cooling efficiency. However, during later disassembly and maintenance, the coolant remaining in the honeycomb plate group will drip uncontrollably, increasing the cleaning difficulty, causing corrosion and damage to surrounding equipment, leading to equipment failures, and at the same time, the large loss of coolant also causes waste of resources.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] As a preferred embodiment of the present invention, the honeycomb panel group is formed by vertically stacking several pairs of honeycomb panels, and the internal holes correspond to each other. The honeycomb panel at the uppermost position corresponds to the top plate, and the honeycomb panel at the lowermost position is lapped on the bottom plate.

[0011] As a preferred embodiment of the present invention, a knob is installed at the end of the synchronizing shaft. The end of the synchronizing shaft is rotatably installed with a card seat, and the card seat is installed on the bottom plate. A swing arm is installed on the synchronizing shaft. A clamping rod is installed at the end of the swing arm, and the clamping rod is arc-shaped. A torsion spring is sleeved on the synchronizing shaft. One end of the torsion spring is clamped on the swing arm, and the other end is clamped on the card seat.

[0012] As a preferred embodiment of the present invention, an installation cavity is formed inside the bottom plate, and a limiting rod is installed on the side wall of the installation cavity. A plurality of pairs of shielding plates are slidably arranged on the limiting rod, and the shielding plates correspond to the honeycomb holes in a staggered manner. A connecting frame is connected between the plurality of pairs of shielding plates.

[0013] As a preferred embodiment of the present invention, a turntable is rotatably installed inside the bottom plate. The turntable is connected to the synchronizing shaft. Protrusions are installed on both side surfaces of the turntable. A pull rod is installed on the shielding plate. A pull plate is installed at the end of a pair of pull rods. A strip-shaped groove is formed on the pull plate, and the strip-shaped groove is slidably connected to the protrusion, and the side wall of the pull plate is flush with the side wall of the shielding plate.

[0014] As a preferred embodiment of the present invention, a slot is vertically formed on the synchronizing shaft. A plurality of pairs of slots are connected to the side wall of the slot. The distance between adjacent slots is adapted to the width of the honeycomb panels in the honeycomb panel group for positioning honeycomb panel groups of different thicknesses. An inner groove is formed on the top plate. A mounting seat is installed on the inner groove. A sliding rod is installed on the side wall of the mounting seat, and the sliding rod is slidably arranged in the corresponding inner groove.

[0015] As a preferred embodiment of the present invention, a guiding hopper is formed on the cooling pipe, and a plurality of pairs of hollow cooling plates are installed inside the guiding hopper.

[0018] The present invention has the following beneficial effects compared with the prior art:

[0019] In the present invention, a part of the air inside the collection hood enters the rectification cavity between the hollow cooling plates through the return pipe. The cooling air slides along the surface of the hollow cooling plates in the rectification cavity to take away heat, optimizing the heat distribution. It can also rectify the air, making the discharged air flow more stable, which is beneficial to the subsequent utilization or treatment of the air. At the same time, when disassembling the honeycomb panel group, the clamping rod is driven by the synchronous shaft to disengage from the clamping slot and slide in cooperation with the sliding rod between the positioning slot and the vertical slot, achieving the purpose of double unlocking. In a complex industrial environment, when a single unlocking method fails, the other unlocking method can still ensure the smooth disassembly of the honeycomb panel group, improving the safety and convenience of the maintenance process. Meanwhile, the synchronous shaft rotates to drive the shutter to automatically block the honeycomb holes, preventing the residual coolant from dripping during transportation, keeping the working environment clean, reducing coolant waste, facilitating the operation of maintenance personnel, and greatly facilitating the maintenance and repair work of the equipment while achieving efficient air rectification.

[0044] For the purpose, technical solutions and advantages of the embodiments of the present invention to be clearer, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. The following embodiments are used to illustrate the present invention.

[0045] Embodiment 1:

[0046] As Figures 1 to 16 shown, a composite air cooling and rectifying device includes a wind tunnel 1 and a matching fan blade 12.

[0047] The bottom of the wind tunnel 1 is connected to a primary cooling pipe 2, and a honeycomb plate group 21 is arranged inside the primary cooling pipe 2. The bottom of the primary cooling pipe 2 is connected to a cooling pipe 3, and a plurality of pairs of hollow cooling plates 321 are communicated with the cooling pipe 3. The bottom of the cooling pipe 3 is connected to a collection hood 4, and a return pipe 5 is connected to the collection hood 4. The return pipe 5 is communicated with the rectifying cavity 33 formed between adjacent hollow cooling plates 321 for rectifying exhaust gas. The coolant inside the collection hood 4 is sprayed onto the honeycomb plate group 21 through the pump body 42; this design realizes the integration of the cooling and rectifying functions. Compared with the traditional technology that relies on an independent rectifying device, it greatly saves the equipment space, reduces the overall floor area, is especially suitable for scenarios such as industrial workshops with limited space, and reduces the site use cost.

[0048] A quick-release sealing assembly is installed on the honeycomb plate group 21. The quick-release sealing assembly includes a synchronous shaft 25 and a bottom plate 22 placed at the bottom of the honeycomb plate group. The synchronous shaft 25 is used to snap the connected clamping rod 254 into the corresponding card slot 255 opened on the side wall of the primary cooling pipe, and also drives the shutter 23 sliding inside the bottom plate 22 to seal the honeycomb holes 221 opened on its surface. The synchronous shaft 25 is provided with a positioning slot 265, and the positioning slot 265 is snapped with the top plate 26 installed inside the primary cooling pipe. The setting of this quick-release sealing assembly provides a convenient basis for the subsequent maintenance of the honeycomb plate group, reducing the time and labor costs required for maintenance.

[0049] As Figures 1 to 16As shown, in the specific embodiment, a horn cover 11 is connected to the top of the air duct 1. A cross 122 is installed inside the air duct 1, and a fan 121 is installed at the central position of the cross 122. The output end of the fan 121 is interconnected with the rotation center of the fan blade 12. This structural design can efficiently introduce external air into the device, provide a stable air source for subsequent cooling and rectification processes, and ensure the continuous operation of the entire device.

[0050] As Figures 1 to 16 shown, further, the honeycomb panel group 21 is vertically stacked by several pairs of honeycomb panels 211, and the internal holes correspond to each other. The honeycomb panel 211 at the uppermost position corresponds to the top plate 26, and the honeycomb panel 211 at the lowermost position is lapped on the bottom plate 22. This structural design has significant advantages. It not only increases the contact area between the coolant and air, improves the effect of direct contact cooling, enables air to be cooled more fully, and greatly improves the cooling efficiency; but also has high flexibility and can increase the number of honeycomb panels 211 arbitrarily according to actual needs. By flexibly adjusting the number of honeycomb panels 211, the ratio between it and the hollow cooling plate 321 on the cooling pipe 3 can be precisely controlled. In scenarios with large air treatment requirements and extremely high cooling efficiency requirements, increasing the number of honeycomb panels 211 can strengthen the heat exchange process between the coolant and air, and cooperate with the hollow cooling plate 321 to further improve the overall cooling capacity; while in the case of small air treatment volume or strict restrictions on equipment energy consumption, reducing the number of honeycomb panels 211 to make the ratio between the two suitable can not only meet the cooling requirements but also avoid energy waste, enabling the device to maintain an efficient and energy-saving operating state under different working conditions, and significantly improving the applicability and economy of the equipment.

[0051] Example 2:

[0052] Based on Example 1, the difference in this example is that: as Figures 1 to 16 shown, a knob 251 is installed at the end of the synchronous shaft 25. A clamping seat 252 is rotatably installed at the end of the synchronous shaft 25, and the clamping seat 252 is installed on the bottom plate 22. A swing arm 253 is installed on the synchronous shaft 25, a clamping rod 254 is installed at the end of the swing arm 253, and the clamping rod 254 is arc-shaped. A torsion spring 256 is sleeved on the synchronous shaft 25. One end of the torsion spring 256 is clamped on the swing arm 253, and the other end is clamped on the clamping seat 252. Such a structural design makes the unlocking operation more convenient. Maintenance personnel only need to rotate the knob 251 to easily disengage the clamping rod 254 from the card slot 255, greatly shortening the maintenance time and improving the usability of the equipment, while the torsion spring 256 facilitates later resetting.

[0053] As Figures 1 to 16As shown, in the specific implementation, an installation cavity 222 is formed inside the bottom plate 22, and a limiting rod 232 is installed on the side wall of the installation cavity 222. A plurality of pairs of shielding plates 23 are slidably arranged on the limiting rod 232, and the shielding plates 23 are staggered and corresponding to the honeycomb holes 221. A connecting frame 231 is connected between the plurality of pairs of shielding plates 23. This design ensures the stability and accuracy of the shielding plates 23 during the sliding process, and ensures that the honeycomb holes can be reliably blocked when the honeycomb panel group is disassembled, preventing the coolant from dripping.

[0054] As Figures 1 to 16 shown, further, a turntable 24 is rotatably installed inside the bottom plate 22. The turntable 24 is connected to the synchronous shaft 25. Protrusions 241 are installed on both surfaces of the turntable 24. A pull rod 244 is installed on the shielding plate 23. A pull plate 242 is installed at the end of a pair of pull rods 244. A strip-shaped groove 243 is formed on the pull plate 242, and the strip-shaped groove 243 is slidably connected to the protrusion 241, and the side wall of the pull plate 242 is flush with the side wall of the shielding plate 23. Through the rotation of the synchronous shaft 25, this structure can accurately control the movement of the shielding plate 23, realize the automatic blocking of the honeycomb holes, avoid the waste of coolant, and reduce the maintenance cost.

[0055] Example 3:

[0056] Based on Example 2, the difference from this example is that as Figures 1 to 16 shown, a slot 264 is vertically formed on the synchronous shaft 25. A plurality of pairs of slots 264 are connected to the side wall of the slot 264. The distance between adjacent slots 264 is adapted to the width of the honeycomb panel 211 in the honeycomb panel group 21 for positioning honeycomb panel groups 21 with different thicknesses. An inner groove 261 is formed on the top plate 26. A mounting seat 262 is installed on the inner groove 261. A sliding rod 263 is installed on the side wall of the mounting seat 262, and the sliding rod 263 is slidably arranged in the corresponding inner groove 261. This design enables the device to adapt to honeycomb panel groups of different specifications, improves the versatility of the equipment, reduces the additional procurement cost caused by equipment adaptation problems, and users do not need to purchase multiple sets of equipment for honeycomb panel groups with different thicknesses.

[0057] As Figures 1 to 16 shown, in the specific implementation, a guiding hopper 32 is formed on the cooling pipe 3, and a plurality of pairs of hollow cooling plates 321 are installed inside the guiding hopper 32. The ends of the hollow cooling plates 321 are communicated with the collecting hood 4. A notch 31 is formed on the side wall of the cooling pipe 3, and the notch 31 is communicated with the return pipe 5. An air outlet 311 is formed on the other side wall of the cooling pipe 3, and the air outlet 311, the notch 31, the return pipe 5 and the rectifying cavity 33 are communicated with each other. This structure optimizes the air flow path in the device, enables the air to be cooled and rectified more smoothly, improves the overall processing efficiency, and ensures the stability and quality of the discharged air.

[0058] AsFigures 1 to 16 As shown in the figure, further, an observation window frame 41 is embedded on the surface of the collection cover 4. An acrylic board for easy observation is installed on the observation window frame 41, and scale lines indicating the liquid content inside the collection cover 4 are engraved on the acrylic board. Through the observation window frame 41 and the scale lines, maintenance personnel can understand the remaining amount of the coolant in real time, supplement the coolant in a timely manner, ensure the continuous and stable operation of the device, reduce equipment failures and downtime caused by insufficient coolant, and improve production efficiency. A pump body 42 is installed on the side wall of the collection cover 4, and the water inlet end of the pump body 42 is communicated with the inside of the collection cover 4. A connecting pipe 421 is installed at the water outlet end of the collection cover 4. The end of the connecting pipe 421 penetrates through the primary cooling pipe 2. A pipe group 43 is installed inside the primary cooling pipe 2, and the connecting pipe 421 is connected to the pipe group 43. A number of pairs of nozzles 431 are installed at the bottom of the pipe group 43, and the nozzles 431 are placed above the honeycomb panel group 21.

[0059] The implementation principle of a composite air cooling and rectifying device of the present invention is as follows: First, start the fan 121. The fan 121 drives the fan blades 12 to rotate, and introduces external air into the air duct 1 through the horn cover 11. The primary cooling pipe 2 connected to the bottom of the air duct 1 preliminarily cools the incoming air. After the air enters the primary cooling pipe 2, it will pass through the honeycomb panel group 21 provided inside. The coolant inside the collection cover 4 passes through the pump body 42, and is sprayed from the nozzles 431 to the honeycomb panel group 21 through the connecting pipe 421 and the pipe group 43. The coolant forms a water film on the honeycomb panel group 21, and directly contacts and cools the passing air, reducing the air temperature. During this cooling process, the coolant after heat exchange with the air will carry the heat absorbed from the air and flow downward along the surface of the honeycomb panel group 21, and finally all fall into the collection cover 4.

[0060] During the cooling process, the cooling pipe 3 connected to the bottom of the primary cooling pipe 2 further plays a role. A number of pairs of hollow cooling plates 321 communicated with the cooling pipe 3 can, on the one hand, exchange heat with the passing air through its own metal material to further reduce the air temperature; on the other hand, the air coming from the primary cooling pipe 2 flows inside the cooling pipe 3, and finally all the air will enter the collection cover 4. The collection cover 4 converges the air flowing in from the cooling pipe 3 and the coolant that has participated in heat exchange and fallen from the honeycomb panel group 21.

[0061] Part of the air in the collection hood 4 will enter the rectification cavity 33 formed between adjacent hollow cooling plates 321 through the return pipe 5. During the rectification process, the cooled air slides along the surface of the hollow cooling plates in the rectification cavity 33. Since the hollow cooling plates 321 were at a relatively high temperature due to heat exchange with hot air previously, the cooling air can carry away the heat on the surface of the hollow cooling plates. This not only helps to maintain the continuous heat exchange performance of the hollow cooling plates, ensuring a good cooling effect on the air subsequently entering the cooling pipe 3, but also optimizes the overall heat distribution of the cooling device and improves the energy utilization efficiency. The air that has been rectified and further participates in heat exchange finally exits from the air outlet 311, achieving the rectification effect on the air and making the discharged air flow more stable.

[0062] The coolant falling into the collection hood 4 is not wasted. Under the action of the pump body 42, the coolant in the collection hood 4 will pass through the connecting pipe 421 and the pipe group 43 again and be sprayed from the nozzle 431 onto the honeycomb plate group 21 to start a new round of cooling operation on the air. In this way, it circulates repeatedly, achieving the purpose of recycling the coolant, greatly improving the utilization efficiency of resources, and ensuring the continuous and stable operation of the entire composite air cooling and rectification device.

[0063] For the maintenance of the honeycomb plate group 21, when it needs to be disassembled, turn the knob 251 to drive the synchronous shaft 25 to rotate. When the synchronous shaft 25 rotates, the swing arm 253 installed on it will rotate accordingly. Due to the action of the torsion spring 256, the clamping rod 254 at the end of the swing arm 253 will gradually disengage from the corresponding slot 255 opened on the side wall of the primary cooling pipe, thereby achieving the purpose of unlocking.

[0064] Moreover, when the synchronous shaft 25 rotates, the sliding rod on the top plate 26 will slide synchronously in the positioning slot of the synchronous shaft 25 and then slide into the vertical slot, which also plays a role in unlocking. In cooperation with the disengagement of the clamping rod 254 from the slot 255, it achieves the purpose of double unlocking. The double unlocking design greatly improves the safety and convenience of the maintenance process. In a complex industrial environment, the equipment may bear additional stress due to various accidental factors. If a single unlocking method fails, it may be difficult to disassemble the honeycomb plate group 21. The double unlocking is mutually redundant. Even if the clamping rod 254 becomes stuck or abnormal due to long-term use, the unlocking of the sliding rod can still ensure that the honeycomb plate group 21 can be taken out smoothly, and vice versa. At this time, the entire honeycomb plate group 21 can be taken out from the primary cooling pipe 2 more safely and conveniently for maintenance or replacement.

[0065] Meanwhile, the rotation of the synchronization shaft 25 drives the rotation of the turntable 24 connected thereto. The protrusions 241 installed on both surfaces of the turntable 24 slide within the strip-shaped grooves 243 formed in the pull plate 242, thereby driving the movement of the pull plate 242. The pull plate 242 pulls the shielding plate 23 to slide on the limit rod 232 through the pull rod 244, causing the shielding plate 23 to automatically block the honeycomb holes 221 formed on the surface of the bottom plate 22. This structural design is extremely ingenious and fully demonstrates its advantages when disassembling the honeycomb plate group 21. When it is necessary to remove the honeycomb plate group 21 from the primary cooling tube 2 for maintenance or replacement, since the honeycomb plate group 21 has participated in the air cooling work before, a large amount of coolant will remain on the surface and in the honeycomb holes. If the honeycomb holes are in an open state during the handling process, the coolant will continuously drip, which will not only cause the working environment to be wet and messy, affecting the cleanliness and safety of the workshop, but also may lead to waste of the coolant. However, the shielding plate 23 automatically blocks the honeycomb holes when the synchronization shaft 25 rotates, which can effectively prevent the coolant from dripping during the handling process, greatly facilitating the handling and subsequent maintenance operations of the maintenance personnel for the honeycomb plate group 21, ensuring that the maintenance work can be smoothly carried out in a relatively clean and dry environment. At the same time, it also reduces the coolant loss and improves the resource utilization efficiency.
