Description

Technical Field

[0001] This invention relates to the field of circulating fan technology, specifically to a window circulating fan with filtration and purification and its processing equipment. Background Technology

[0002] During welding operations, the high temperature of the electric arc causes the metal and welding materials to evaporate and oxidize, producing a large amount of harmful gases containing metal fumes, nitrogen oxides and fine particulate matter. If these pollutants are directly emitted or spread in the workshop, they will not only seriously pollute the workshop environment and accelerate the wear and corrosion of production equipment, but will also enter the body of workers through the respiratory system, posing a long-term and serious threat to their health.

[0003] Currently, to improve the working environment in welding workshops, the common practice is to use overall ventilation or install local fume purification devices at workstations. However, in practical applications, these solutions still face the following technical bottlenecks: Traditional welding fume purification equipment mostly uses single-filter dust removal, which cannot neutralize acidic harmful gases such as nitrogen oxides generated during welding, resulting in the emission gas still containing gaseous pollutants and failing to fundamentally improve emission safety. In addition, in some solutions that use wet dust removal or gas-liquid mixing purification, the dust-laden airflow often directly carries high concentrations of solid particles into the circulation pipeline. Driven by the high-speed airflow, this accelerates the wear of the pipeline and impeller, thereby reducing the equipment's filtration and purification effect and service life. Summary of the Invention

First, it intercepts large particulate impurities, then uses the water mist curtain to capture fine particulate matter. At the same time, it reacts chemically with acidic harmful gases such as nitrogen oxides in the airflow, effectively removing hazardous substances from the gas, ensuring the safety of the emitted air, significantly reducing the concentration of harmful gases in the welding workshop, providing a safer and healthier working environment for workers, and improving the overall environmental protection effect.

[0021] 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.

[0022] Example 1: Reference Figures 1-7A window-mounted circulating fan for filtration and purification includes an air guide chamber 1, an air inlet chamber 2 fixedly connected to the outer wall of the air guide chamber 1, and a filter cover 7 fixedly connected to the air inlet end of the air inlet chamber 2 for intercepting large particulate impurities carried in the airflow. It also includes: air guide blades 3 installed inside the air guide chamber 1, wherein a dual-axis motor 31 is fixedly connected to the inner wall of the air guide chamber 1, and the air guide blades 3 are fixedly connected to the output end of the dual-axis motor 31; a purification section disposed on the air inlet chamber 2, which cleans and purifies the airflow entering the air inlet chamber 2 by generating atomized liquid; and a flow interception section disposed inside the air inlet chamber 2, which intercepts and circulates the atomized liquid.

[0023] Reference Figures 1-3 The purification section includes an atomizing nozzle 4, a spiral channel 21 is provided in the air intake chamber 2, and a purification chamber 41 is provided between multiple sets of spiral channels 21. The atomizing nozzle 4 is fixedly connected to the top of the purification chamber 41. A base 24 is fixedly connected to the bottom of the air intake chamber 2. A liquid storage tank 42 is fixedly connected to the base 24. The liquid storage tank 42 contains an alkaline treatment liquid. A submersible pump 43 is installed in the liquid storage tank 42. The output end of the submersible pump 43 is connected to the top of the atomizing nozzle 4 through a liquid guide pipe 44.

[0024] With the above-described structure, the submersible pump 43 is activated to draw alkaline purification liquid from the storage tank 42 and deliver it to the atomizing nozzle 4 through the liquid guide pipe 44. The atomizing nozzle 4 atomizes the liquid at the top of the purification chamber 41, forming a water mist curtain. When the airflow passes through the water mist curtain, the finer particles inside are first captured by the water mist, effectively removing solid particles and preventing wear on subsequent pipes and components, thus improving the durability of the equipment. Secondly, the nitrogen oxides and acidic gases contained in the airflow react with the alkaline purification liquid, thereby removing harmful gases from the airflow, ensuring the safety of the airflow discharge, improving environmental protection, and reducing the content of harmful gases in the welding workshop, thus improving the safety of welding work. Furthermore, after the mixture of water mist and airflow enters the subsequent spiral channel 21, it is forcibly guided into a high-speed rotating spiral airflow, significantly extending the travel distance of the airflow within the purification area. This allows the pollutants in the airflow to have more time and opportunity to come into contact, collide, and be adsorbed with the ultrafine water mist droplets. In addition, the rotating airflow generates a strong turbulence effect, breaking the laminar flow state, which allows the water mist and air to mix more evenly and more vigorously. This efficient mixing state greatly improves the efficiency of water mist in capturing pollutants. Furthermore, the rotational motion generated by the spiral channel 21 naturally generates centrifugal force. Under the action of centrifugal force, the water mist droplets that have already captured pollutants and have a relatively larger mass are thrown towards the outer inner wall of the spiral channel 21. This process is the first step of "gas-liquid separation," which causes the contaminated water mist and the purified air to begin to separate, creating favorable conditions for the subsequent interception section to perform final separation and liquid recovery.

[0025] Reference Figures 3-7 The intercepting section includes a centrifugal ring 5, which is rotatably connected to the air intake chamber 2 and located at the output end of the spiral channel 21. Multiple sets of wind turbine blades 51 are arranged in a ring array on the inner wall of the centrifugal ring 5. A centrifugal disk 52 is fixedly connected to the other end of each set of wind turbine blades 51. Multiple sets of vortex blades 53 are arranged in a ring array on the windward surface of the centrifugal disk 52, and the windward surface of the centrifugal disk 52 is designed in a frustum shape. The other side of the dual-shaft motor 31 extends into the air intake chamber 2 and is fixedly connected to a drive magnetic ring 32. The drive magnetic ring 32 and the centrifugal disk 52 are magnetically attracted to each other. A water filter membrane 54 is fixedly connected to both the centrifugal ring 5 and the centrifugal disk 52 on the side closest to the output end of the spiral channel 21. A water collection chamber 55 is opened inside the centrifugal ring 5. Multiple sets of drainage holes 56 connected to the water collection chamber 55 are opened on the inner wall of the centrifugal ring 5. That is, when the centrifugal disk 52 rotates, the water is intercepted... The water remaining on the surface of the filter membrane 54 will flow into the water collection chamber 55 through the drain hole 56; the centrifugal disc 52 is provided with a flow interception chamber 521, and multiple sets of flow interception grooves 522 are equally spaced on the windward surface of the centrifugal disc 52 located between two adjacent sets of vortex blades 53. The flow interception grooves 522 are connected to the flow interception chamber 521. Each set of wind turbine blades 51 is provided with a flow guide groove 511. The two ends of the flow guide groove 511 are connected to the flow interception chamber 521 and the water collection chamber 55 respectively; the bottom of the air inlet chamber 2 is fixedly connected to the return box 6, and multiple sets of return holes 57 are equally spaced on the outer ring wall of the centrifugal ring 5. When the centrifugal ring 5 rotates, each set of return holes 57 is intermittently connected to the return box 6. The bottom of the return box 6 is fixed and connected to the return pipe 61. The bottom end of the return pipe 61 is connected to the top of the inner cavity of the liquid storage tank 42, and the upper part of the inner cavity of the liquid storage tank 42 is fixedly connected to the filter plate 62.

[0026] With the above structure, when the dual-shaft motor 31 is running, the magnetic attraction between the drive magnetic ring 32 and the centrifugal disk 52 will drive the centrifugal disk 52 to rotate. The high-speed spiral airflow output from the spiral channel 21 will blow towards the windward side of the centrifugal disk 52. With the setting of the vortex blades 53, the rotation speed of the centrifugal disk 52 can be further accelerated. At this time, the centrifugal disk 52 will rotate rapidly and generate centrifugal force. At this time, the gas and liquid impacting the centrifugal disk 52 will move towards its edge. With the setting of the interception groove 522, the liquid and reaction products can be initially recovered. At this time, the liquid and reaction products will enter the interception chamber 521 along the interception groove 522 and enter the water collection chamber 55 along the guide groove 511. In addition, the filter membrane 54 further enables gas-liquid separation, allowing the liquid and reaction products to be thrown along the filter membrane 54 onto the inner ring wall of the centrifugal ring 5, and then enter the water collection chamber 55 through the drain hole 56. The liquid and reaction products recovered in the water collection chamber 55 will enter the reflux box 6 through the reflux hole 57, and finally flow back to the storage tank 42 through the reflux pipe 61. After being filtered by the filter plate 62, it will be recirculated into the atomizing nozzle 4, thereby achieving efficient recovery of atomized liquid, reducing liquid consumption, and effectively improving energy saving.

[0027] Furthermore, as mentioned above, the centrifugal force effectively prevents the reaction products mixed in the liquid from accumulating or adhering inside the equipment, thus achieving effective anti-clogging and protection.

[0028] Reference Figures 4-6 Multiple sets of accelerating blades 33 are arranged in a ring array on the outer ring wall of the driving magnetic ring 32. A flow channel 22 is provided on the inner wall of the air intake chamber 2. The ends of the accelerating blades 33 extend into the flow channel 22. The bottom of the flow channel 22 is fixed and connected to an auxiliary flow pipe 23. The other end of the auxiliary flow pipe 23 is connected to the return pipe 61.

[0029] With the above-mentioned structure, and in addition, when the centrifugal disc 52 and the drive magnetic ring 32 rotate, the airflow after solid-liquid separation can be accelerated by the arrangement of the wind-driven blades 51 and the accelerating blades 33, thereby achieving secondary acceleration of the airflow and enabling it to enter the air guide chamber 1 more quickly. This significantly improves the speed and flow rate of the final output airflow, allowing the purified air to be delivered more quickly and in larger quantities, greatly improving the ventilation efficiency of the circulating fan. Furthermore, some unfiltered liquid, after impacting the accelerating blades 33, will be thrown into the diversion channel 22 by the centrifugal force generated by the accelerating blades 33, and finally flow back to the liquid storage tank 42 through the auxiliary flow pipe 23 and the return pipe 61, achieving further separation and recovery of the liquid. This effectively prevents the liquid from entering the air guide chamber 1 and causing corrosion and damage to its internal equipment, thus improving the overall service life of the equipment.

[0030] Reference Figures 1-7In this invention, when in use, the dual-axis motor 31 is first turned on, which drives the air guide vane 3 to rotate in the air guide chamber 1. At this time, a negative pressure suction force is generated in the air guide chamber 1 near the air intake chamber 2, causing the airflow in the welding workshop to move into the air intake chamber 2 and enter each set of spiral channels 21 after passing through the filter cover 7. This allows for the preliminary filtration of large particulate impurities in the airflow. The filtered airflow enters the spiral channel 21 for acceleration and then enters the purification chamber 41. Simultaneously, the submersible pump 43 is activated to draw alkaline purification liquid from the storage tank 42 and deliver it to the atomizing nozzle 4 through the liquid guide pipe 44. The atomizing nozzle 4 atomizes the liquid at the top of the purification chamber 41, forming a water mist curtain. When the airflow passes through the water mist curtain, the finer particles inside are first captured by the water mist, effectively removing solid particles and preventing wear on subsequent pipes and components, thus improving the durability of the equipment. Secondly, the nitrogen oxides and acidic gases contained in the airflow react with the alkaline purification liquid, thereby removing harmful gases from the airflow, ensuring the safety of the airflow discharge, improving environmental protection, and reducing the content of harmful gases in the welding workshop, thus improving the safety of welding work.

[0031] Next, the mixture of water mist and airflow will enter the subsequent spiral channel 21 and be forcibly guided into a high-speed rotating spiral airflow. This significantly extends the travel distance of the airflow within the purification area, allowing pollutants in the airflow more time and opportunity to come into contact, collide, and be adsorbed by the ultrafine water mist droplets. Furthermore, the rotating airflow generates a strong turbulence effect, breaking the laminar flow state and enabling the water mist and air to mix more evenly and vigorously. This highly efficient mixing state greatly improves the efficiency of water mist in capturing pollutants. In addition, the rotational motion generated by the spiral channel 21 will naturally generate centrifugal force. Under the action of centrifugal force, the water mist droplets that have already captured pollutants and have a relatively larger mass will be thrown towards the outer inner wall of the spiral channel 21. This process is the first step of "gas-liquid separation," which causes the contaminated water mist and the purified air to begin to separate, creating favorable conditions for the subsequent interception section to perform final separation and liquid recovery.

[0032] When the dual-axis motor 31 is running, the magnetic attraction between the drive magnetic ring 32 and the centrifugal disk 52 will drive the centrifugal disk 52 to rotate. The high-speed spiral airflow output from the spiral channel 21 will blow towards the windward side of the centrifugal disk 52. With the setting of the vortex blades 53, the rotation speed of the centrifugal disk 52 can be further accelerated. At this time, the centrifugal disk 52 will rotate rapidly and generate centrifugal force. At this time, the gas and liquid impacting the centrifugal disk 52 will move towards its edge. With the setting of the interception groove 522, the liquid and reaction products can be initially recovered. At this time, the liquid and reaction products will enter the interception chamber 521 along the interception groove 522 and enter the water collection chamber 55 along the guide groove 511. In addition, the filter membrane 54 further enables gas-liquid separation, allowing the liquid and reaction products to be thrown along the filter membrane 54 onto the inner ring wall of the centrifugal ring 5, and then enter the water collection chamber 55 through the drain hole 56. The liquid and reaction products recovered in the water collection chamber 55 will enter the reflux box 6 through the reflux hole 57, and finally flow back to the storage tank 42 through the reflux pipe 61. After being filtered by the filter plate 62, it will be recirculated into the atomizing nozzle 4, thereby achieving efficient recovery of atomized liquid, reducing liquid consumption, and effectively improving energy saving.

[0033] Furthermore, when the centrifugal disc 52 and the drive magnetic ring 32 rotate, the arrangement of the fan blades 51 and the accelerating blades 33 accelerates the airflow after solid-liquid separation, achieving secondary acceleration of the airflow and allowing it to enter the air guide chamber 1 more quickly. This significantly increases the speed and flow rate of the final output airflow, enabling the purified air to be delivered more quickly and in larger quantities, greatly improving the ventilation efficiency of the circulating fan. Moreover, some unfiltered liquid, after impacting the accelerating blades 33, is thrown into the guide channel 22 by the centrifugal force generated by the accelerating blades 33, and finally flows back to the liquid storage tank 42 via the auxiliary flow pipe 23 and the return pipe 61, achieving further separation and recovery of the liquid. This effectively prevents liquid from entering the air guide chamber 1 and causing corrosion and damage to its internal equipment, thus improving the overall service life of the equipment.

[0034] Example 2: Reference Figure 8 , Figure 9To facilitate the processing and production of matching vortex blades 53, a processing device for a window-mounted circulating fan with filtration and purification is proposed. This device includes a fixed template 8, on the side wall of which an injection molding machine 81 is fixedly installed. Multiple sets of guide rods 82 are fixedly connected to the other side of the fixed template 8. A movable template 83 is slidably sleeved between the guide rods 82. An injection mold 84 is fixedly connected to the side of the movable template 83 facing the fixed template 8. Side plates 85 are fixedly connected to the ends of the guide rods 82, and the side plates 85 are close to the movable template. A mold-closing cylinder 86 is fixedly connected to one side of the mold 83. The telescopic end of the mold-closing cylinder 86 is fixedly connected to the side wall of the moving mold plate 83. When the vortex blade 53 needs to be processed and produced, the production raw material is first added into the injection molding machine 81. Then, the mold-closing cylinder 86 is started to extend and push the moving mold plate 83 along the guide rod 82 towards the fixed mold plate 8, so that the injection mold 84 and the fixed mold plate 8 are closed. Finally, the injection molding machine 81 is controlled to inject the raw material into the mold cavity. After the raw material cools down, the moving mold plate 83 is removed, thereby obtaining the required vortex blade 53.
