An axial air duct assembly and an axial blower

Abstract

The present invention discloses an axial-flow air duct assembly and an axial-flow hair dryer, belonging to the field of axial-flow fans. It includes an outer shell of the axial-flow fan, an asynchronous induction motor, an impeller fan, a heat conduction mechanism, and an adsorption mechanism. Guide air outer notches are fixedly installed on one side of the outer disc housing facing the impeller fan, and a set of cylindrical housings are movably installed at the central axis position inside each outer disc housing. Through the circumferentially distributed adsorption units embedded in the air duct housing and using the airflow generated by the impeller to drive the rotation of the cylindrical housing, the periodic switching of the adsorption and regeneration double cavities is realized. While one cavity continuously adsorbs moisture and VOCs, the other cavity is desorbed and regenerated by means of the waste heat of the motor. Moreover, the service life of the active material is significantly extended through the adsorption and regeneration cycle mechanism, and stable purification efficiency can be maintained especially in high-temperature and high-humidity environments, solving the technical problems of pore blockage and frequent filter material replacement in the traditional scheme.

Description

Technical Field

[0001] The present invention relates to the technical field of axial fans, and more specifically, to an axial air duct assembly and an axial blower. Background Art

[0002] As a core component of the ventilation system, the axial air duct assembly performs excellently in gas transportation and heat dissipation. However, it is difficult for the existing technologies to jointly handle humidity and VOCs pollution. The traditional structure relies on the basic combination of an axial fan, a deflector hood, and a housing, and obvious defects are exposed in environments with high temperature and humidity or corrosive gases: humid air is likely to cause motor rust and microbial growth, while the direct emission of VOCs aggravates environmental pollution. Although the current external purification module can solve the problem independently, it increases the air resistance, leading to increased energy consumption, increased airflow noise, and it is difficult to balance the purification efficiency and aerodynamic performance.

[0003] The insufficient environmental adaptability of axial fans has become a key bottleneck. In a high-humidity environment, water vapor condensation not only reduces the insulation performance of the motor, but also easily forms secondary pollution. At the same time, the existing series purification schemes (such as end filters or adsorption layers) are restricted by the fan air pressure limit and are forced to use low-density filter materials, resulting in frequent problems such as shortened activated carbon adsorption cycles and blockage of filter material pores by water molecules. This passive design severely restricts the comprehensive efficiency of the system.

[0004] Especially in the typical case of an existing subtropical electronics workshop, due to the workshop humidity exceeding 75% and containing organic solvent vapors, the traditional axial flow system cannot synchronously handle humid and hot air and aerosol pollutants, resulting in an increase in equipment rust rate and health hazards. When a purification layer is installed at the air outlet in the existing renovation scheme, it often fails due to exceeding the fan load limit. It is impossible to achieve deep integration of humidity regulation and gas purification without affecting the airflow driving efficiency. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an axial air duct assembly and an axial blower, aiming to solve the above technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] An axial air duct assembly includes an outer housing of an axial fan. A plurality of cross beam frames are fixedly connected to the inner wall of the outer housing of the axial fan, and an asynchronous induction motor is fixedly installed through the cross beam frames at the position of the axis center inside the outer housing of the axial fan. An impeller fan is fixedly installed on the output end of the asynchronous induction motor. A heat conduction mechanism is sleeved on the outer surface of the asynchronous induction motor. A plurality of groups of adsorption mechanisms are arranged in a circular pattern at the position outside the blowing end of the impeller fan on the housing of the outer housing of the axial fan;

[0008] The adsorption mechanism includes an outer disc housing. On one side of the outer disc housing facing the impeller fan, a wind guiding outer notch is fixedly installed. And at the central axis position inside each outer disc housing, a set of cylindrical housings are movably installed, so as to drive the cylindrical housings to rotate by the wind generated by the rotation of the impeller fan through the wind guiding outer notch. The output ends of the heat conduction mechanism all extend into the outer disc housings on the same side;

[0009] Among them, partition plates are fixedly connected to the inner walls of the cylindrical housings, and the cylindrical housings are divided into two sets of symmetrical isolation chambers by the partition plates to respectively fill adsorption particles. The heat conduction mechanism extending into the outer disc housing is used to make one adsorption end in the two sets of symmetrical isolation chambers adsorb moisture, and the other adsorption end is used to be regenerated by the hot air of the heat conduction mechanism.

[0010] As a further scheme of the present invention: first counterweights are fixedly connected to the positions on both sides of the partition plate on the inner wall of the cylindrical housing. Second counterweights are fixedly connected to the positions between the two first counterweights on the inner wall of the cylindrical housing. And outer arc flaps that can be hermetically attached to the second counterweights are hinged on the outer side edges of the first counterweights. Visual cover plates are fixedly installed on the outer disc surfaces of the cylindrical housings. The whole outer disc housing is half located inside the axial flow fan outer housing and half located outside the axial flow fan outer housing. And air permeable bottom groove covers are fixedly installed at the positions of the outer disc housing inside the axial flow fan outer housing.

[0011] As a further scheme of the present invention: triangular brackets are fixedly connected to the isolation chambers on both sides of the partition plate. And a set of stirring brackets are movably installed at the three corner ends of the triangular brackets. And one set of stirring brackets faces the second counterweight on the same side. And first gear columns are fixedly connected to both sides of the central axis ends of each set of stirring brackets. And first track sleeves are meshed on the outer surfaces of the first gear columns at the three corner ends of the triangular brackets.

[0012] As a further scheme of the present invention: second reserved sleeve openings are formed at the positions on the surface of the second counterweight facing the first gear columns on both sides of the stirring bracket. And movable sleeves are fixedly installed at the positions in the middle of the outer surface of the second counterweight. Coaxial support rods are movably installed on the surface of the movable sleeve. And guide fan blade frames are fixedly installed at the positions on both sides of the coaxial support rod facing the second reserved sleeve opening. Second track sleeves are meshed on the shaft rods of the guide fan blade frames. And one end of the second track sleeve far from the shaft rod of the guide fan blade frame is meshed and sleeved on the first gear column facing the second reserved sleeve opening.

[0013] As a further solution of the present invention: A number of groups of full-coverage air guide plates are fixedly connected to the outer surface of the outer arc flap at positions far from the second counterweight, and a number of groups of air guide plates with notches are fixedly connected to the outer surface of the outer arc flap at positions close to the second counterweight. Brush ends are arranged on the outer extending end faces of the air guide plates with notches and the full-coverage air guide plates, and the brush ends are all attached to one side of the breathable bottom groove cover.

[0014] As a further solution of the present invention: Magnetic attraction plates are fixedly installed on the outer surface of the cylindrical sleeve at positions where the two first counterweights are flush, and infrared external spotlights are fixedly installed on the sides of the magnetic attraction plates. A limiting module aligned with the magnetic attraction plate in the horizontal state of the partition plate is also fixedly installed at the side end position of the breathable bottom groove cover far from the air guide outer notch. The limiting module includes an electromagnetic attraction block, and an infrared detection block is fixedly installed on the side of the electromagnetic attraction block.

[0015] The present invention also provides an axial flow blower: The axial flow blower is composed of an asynchronous induction motor and an impeller fan at the output end of the asynchronous induction motor. The axial flow air duct assembly is installed outside the axial flow blower through a cross beam frame, and a groove opening heat conducting sleeve is also fixedly installed on the outer surface of the asynchronous induction motor. The heat conducting mechanism includes a heat preservation outer cylindrical sleeve fixedly installed on the outer surface of the groove opening heat conducting sleeve. A set of first reserved sleeve openings are opened at positions on the outer edge surface of the heat preservation outer cylindrical sleeve flush with each side outer disc sleeve, and heat preservation outer extension sleeves are fixedly connected to the outside of each set of first reserved sleeve openings. The outer extending ends of the heat preservation outer extension sleeves extend into the air guide outer notches on the same side.

[0016] As a further solution of the present invention: The heat conducting mechanism further includes outer extending heat conducting rods sleeved in the heat preservation outer extension sleeves on each side. Heat conducting outer notch sleeve plates are fixedly installed on one side ends of the outer extending heat conducting rods close to the asynchronous induction motor, and the heat conducting outer notch sleeve plates are in corresponding fitting with the groove opening heat conducting sleeves on the same side. Open-ended threaded heat dissipation sleeve heads are fixedly installed at the ends of the outer extending heat conducting rods far from the heat conducting outer notch sleeve plates, and the open-ended threaded heat dissipation sleeve heads are entirely located inside the air guide outer notch.

[0017] As a further solution of the present invention: First hinge sleeves are fixedly installed on the outer disc sleeves on the side opposite to the breathable bottom groove cover, and outer flip sealing covers are movably installed through the first hinge sleeves. The outer flip sealing covers are entirely located outside the axial flow fan outer casing.

[0018] As a further solution of the present invention: An auxiliary supporting hanger is also fixedly installed on the outer surface of the axial flow fan outer casing. The auxiliary supporting hanger is a hanger that can be adjusted in multiple axial directions.

[0019] The above technical solutions provided by the present invention have at least the following beneficial effects compared with the prior art:

[0020] (1) By dynamically coupling the rotary adsorption mechanism with the axial flow air duct, the limitations of traditional external purification modules are overcome. The adsorption units distributed in a circumferential pattern are embedded in the air duct housing, and the airflow generated by the impeller is used to drive the rotation of the cylindrical sleeve, realizing the periodic switching of the adsorption and regeneration double chambers. Among them, the symmetric isolation chamber is accurately positioned under the control of the counterweight system, enabling one chamber to continuously adsorb moisture and VOCs while the other chamber undergoes desorption and regeneration by means of the waste heat of the motor. This avoids the increase in air resistance caused by series-connected filter materials and significantly extends the service life of the active material through the adsorption and regeneration cycle mechanism. Especially in high-temperature and high-humidity environments, stable purification efficiency can be maintained, solving the technical problems of pore blockage and frequent filter material replacement in traditional solutions.

[0021] (2) By setting up a composite regeneration system for heat energy recovery and dynamic diversion, the environmental adaptability is significantly improved. The waste heat generated during the operation of the induction motor is directionally transported to the regeneration chamber through the heat conduction mechanism, and combined with the forced convection formed by the air guiding slots, efficient desorption of the adsorbent is achieved. The linkage design of the guide fan blade frame and the stirring mechanism further strengthens the uniformity of heat transfer, enabling the regeneration process to be completed under low energy consumption conditions. This active regeneration mechanism not only effectively suppresses the condensation risk in high-humidity environments but also reduces the additional energy consumption of the system through closed-loop thermal management, being more energy-efficient than traditional electric heating regeneration methods and especially suitable for industrial scenarios such as electronics workshops that require continuous dehumidification and purification.

[0022] (3) Through the synergistic effect of the counterweight system and the magnetic positioning module, the position accuracy of the chamber switching is ensured. The design of the full-coverage air guiding plate and the brush end continuously cleans the breathable structure during rotation, preventing secondary pollution caused by particulate deposition. The feedback control system composed of infrared detection and electromagnetic locking can identify the adsorption saturation state in real time and trigger the regeneration process, enabling the equipment to maintain the optimal working state under unattended conditions, significantly reducing the operating cost and downtime risk.

[0039] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed Embodiments

[0040] The following describes in detail an axial-flow air duct assembly and an axial-flow blower provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0041] As Figures 1 to 9 shown, an embodiment of the present invention provides an axial-flow air duct assembly, including an outer casing 1 of an axial-flow fan. A plurality of cross beam frames 3 are fixedly connected to the inner wall of the outer casing 1 of the axial-flow fan. An asynchronous induction motor 4 is fixedly installed through the cross beam frames 3 at the position of the axis in the outer casing 1 of the axial-flow fan. An impeller fan 5 is fixedly installed on the output end of the asynchronous induction motor 4. A heat conduction mechanism 6 is sleeved on the outer surface of the asynchronous induction motor 4. A plurality of groups of adsorption mechanisms 7 are arranged in a circular pattern at the position outside the blowing end of the impeller fan 5 on the casing of the outer casing 1 of the axial-flow fan;

[0042] The adsorption mechanism 7 includes an outer disc casing 71. A wind guiding outer notch 74 is fixedly installed on one side of the outer disc casing 71 facing the impeller fan 5. A cylindrical casing 77 is movably installed at the central position inside each outer disc casing 71, so as to drive the cylindrical casing 77 to rotate by the wind generated by the rotation of the impeller fan 5 through the wind guiding outer notch 74. The output ends of the heat conduction mechanism 6 extend into the outer disc casings 71 on the same side;

[0043] Among them, partition plates 78 are fixedly connected to the inner walls of the cylindrical casings 77, and the cylindrical casings 77 are separated into two groups of symmetrical isolation chambers 711 by the partition plates 78 to respectively fill adsorption particles. Cooperating with the heat conduction mechanism 6 extending into the outer disc casings 71, one adsorption end of the two groups of symmetrical isolation chambers 711 is used to adsorb moisture, and the other adsorption end is used to regenerate with the hot air of the heat conduction mechanism 6.

[0044] To solve the problem that existing axial fans cannot efficiently handle humidity and pollutants simultaneously in high-temperature, high-humidity, and VOC-containing environments, the above technical solution is adopted. The above technical solution mainly consists of an axial fan outer casing 1, an asynchronous induction motor 4, an impeller fan 5, a heat conduction mechanism 6, and an adsorption mechanism 7. The axial fan outer casing 1 is a pipe sleeve structure in the prior art and is the outer casing structure of the axial air duct assembly. The configured asynchronous induction motor 4 is an induction motor structure in the prior art. When the induction motor operates, it generates a lot of heat, especially when the load is high or it operates at a non-optimal efficiency point, thus generating more heat to provide a better regeneration environment for the entire system. Moreover, the design of the induction motor in the prior art is relatively mature and the cost is low, making it suitable for long-term continuous operation. The impeller fan 5 configured at the motor output end is a guide fan structure in the prior art and is the core component of the axial fan, responsible for converting mechanical energy into gas kinetic energy. Since the design of the impeller is crucial for the performance of the fan, the number, shape, angle, etc. of the configured blades will affect the airflow characteristics and can be adapted according to different usage environments;

[0045] The adsorption mechanism 7, which is the core component of the axial air duct assembly, includes several groups of outer disc sleeves 71 and air guide outer notches 74 on the sides of the outer disc sleeves 71. Each group of outer disc sleeves 71 is located outside the blowing end of the impeller fan 5 and is arranged in a circular pattern around the outer casing of the axial fan outer casing 1. A cylindrical sleeve 77 is movably installed inside each outer disc sleeve 71. During the process of the asynchronous induction motor 4 driving the impeller fan 5 at its output end to rotate at high speed, the generated wind can be led out through the axial fan outer casing 1 to form an axial air duct. On the one hand, this air duct can drive the airflow in the area to complete the work of axial blowing. On the other hand, it can also blow into the air guide outer notch 74 on the side facing the impeller fan 5. The high-speed air flow entering the air guide outer notch 74 can blow the cylindrical sleeve 77 at the axial center position inside the outer disc sleeve 71. And because the inner walls of the cylindrical sleeve 77 are fixedly connected with partition plates 78, and under the partitioning action of the partition plates 78, the cylindrical sleeve 77 is divided into two groups of symmetrical isolation chambers 711. Adsorption particles are filled in each group of isolation chambers 711 respectively. One group of adsorption ends in the two groups of symmetrical isolation chambers 711 is used to cooperate with the air duct blown out from the axial fan outer casing 1 to adsorb the moisture inside the area, and the other group of adsorption ends is used to cooperate with the hot air of the heat conduction mechanism 6 to regenerate the adsorption-saturated adsorption particles, so as to achieve the working cycle of the entire axial air duct assembly. The adsorption particles configured in each group of isolation chambers 711 have the ability to absorb or adsorb moisture from the air in the prior art. These adsorbents absorb moisture at relatively low temperatures and release moisture at higher temperatures, that is, the regeneration process. For example, silica gel particles are a common adsorbent with good moisture absorption performance and can be regenerated at relatively low temperatures.

[0046] As shown Figures 1 to 9 in the figure, at both ends of the partition plate 78 on the inner wall of the cylindrical casing 77, first counterweight blocks 717 are fixedly connected. At the positions between the two first counterweight blocks 717 on the inner wall of the cylindrical casing 77, second counterweight blocks 710 are fixedly connected. On the outer sides of the first counterweight blocks 717, outer arc flaps 726 that can be hermetically attached to the second counterweight blocks 710 are hinged. On the outer disc surfaces of the cylindrical casing 77, visual cover plates 79 are fixedly installed. The entire outer disc casing 71 is half inside the axial flow fan outer casing 1 and half outside the axial flow fan outer casing 1. At the positions of the outer disc casing 71 inside the axial flow fan outer casing 1, air-permeable bottom groove covers 75 are fixedly installed.

[0047] Among them, the first counterweight blocks 717 and the second counterweight blocks 710 arranged on the outer side of the cylindrical casing 77 together form a stable counterweight system. At both ends of the partition plate 78, first counterweight blocks 717 are fixedly connected. At the positions between the two first counterweight blocks 717 on the inner wall of the cylindrical casing 77, second counterweight blocks 710 are fixedly connected. That is, second counterweight blocks 710 are arranged at the exact middle positions of each side of the isolation chamber 711. The weight of the second counterweight blocks 710 is greater than that of the first counterweight blocks 717. The first counterweight blocks 717 arranged at both ends of the partition plate 78 play a stabilizing role, while the heavier second counterweight blocks 710 play a role in stabilizing the center of gravity. During the rotation of the entire cylindrical casing 77 following the blown air, under the action of the counterweight, the cylindrical casing 77 can improve the stability of the centripetal force and rotate more stably. Further, when the cylindrical casing 77 is not rotating, in the state where the adsorbed particles stored in the two isolation chambers 711 on both sides are the same, due to the weight of the second counterweight blocks 710 being much greater than that of the first counterweight blocks 717, the side with the second counterweight blocks 710 will preferentially dock under the influence of gravity, resulting in the two isolation chambers 711 on both sides of the cylindrical casing 77 always docking one above and one below with the outer casing of the axial flow fan outer casing 1 as the dividing line, forming an arrangement state where half of the isolation chambers 711 inside the cylindrical casing 77 are inside the axial flow fan outer casing 1 and half are outside the axial flow fan outer casing 1. Specifically, it promotes the isolation chamber 711 to better and more stably form an adsorption operation on one side inside the axial flow fan outer casing 1, while the other isolation chamber 711 performs a saturation recovery operation outside the axial flow fan outer casing 1.

[0048] As Figures 1 to 9As shown, triangular brackets 714 are fixedly connected to both of the isolation chambers 711 on both sides of the partition plate 78. A set of stirring brackets 715 are movably installed at the three corner ends of the triangular brackets 714. A set of stirring brackets 715 are facing the second counterweight 710 on the same side. On both sides of the axial center end of each set of stirring brackets 715, first gear columns 716 are fixedly connected. The outer surfaces of the first gear columns 716 at the three corner ends of the triangular brackets 714 are all engaged with first track sleeves 718.

[0049] Among them, the configured triangular bracket 714 is overall similar to a triangular arrow structure and is used to movably sleeve three sets of stirring brackets 715. The configured first gear column 716 is an axial center rod structure with tooth openings on its outer surface in the prior art. The corresponding configured first track sleeve 718 is a track structure used to engage the first gear columns 716 outside the three sets of stirring brackets 715, so that the driving axles of the three sets of stirring brackets 715 are engaged on one track.

[0050] As Figures 1 to 9 shown, second reserved sleeve openings 721 are provided at the positions of the surface of the second counterweight 710 facing the first gear columns 716 on both sides of the stirring bracket 715. A movable sleeve 722 is fixedly installed at the exact middle position of the outer surface of the second counterweight 710. A coaxial support rod 723 is movably installed on the surface of the movable sleeve 722. Guide fan blade frames 724 are fixedly installed at the positions of both sides of the coaxial support rod 723 facing the second reserved sleeve opening 721. Second track sleeves 725 are engaged on the axle rods of the guide fan blade frames 724. One end of the second track sleeve 725 away from the axle rod of the guide fan blade frame 724 is engaged and sleeved on the first gear column 716 facing the second reserved sleeve opening 721.

[0051] Among them, the second reserved socket 721 arranged on the surface of the second counterweight 710 is, on the one hand, to provide an activity area for the second crawler sleeve 725 passing through, so that the second crawler sleeve 725 can drive the first gear column 716 facing the second counterweight 710 to rotate following the rotation of the guide fan blade frame 724, providing stable driving force for the three groups of stirring brackets 715. Through the rotation and stirring of the three groups of stirring brackets 715, not only can the particles in the cavity flow, but also through the adsorption performance, heat can better contact each adsorption particle during the process of restoring activity, improving the restoration efficiency. On the other hand, the second reserved socket 721 arranged on the surface of the second counterweight 710 can also cooperate with the rotating guide fan blade frame 724 to press the hot air in the outer disc housing 71 into the saturated restoration isolation cavity 711 inside the cylindrical housing 77. And in order to ensure the stable operation of the two-sided isolation cavity 711, air-permeable openings are provided on the outer surface of the housing of the cylindrical housing 77, that is, on the surface of the outer arc flap 726, which is similar to the air-permeable bottom groove cover 75 as a whole, and can better introduce gas and hot air.

[0052] As Figures 1 to 9 shown, several groups of full-coverage air guide plates 719 are fixedly connected to the positions on the outer surface of the outer arc flap 726 far from the second counterweight 710, and several groups of slotted air guide plates 720 are fixedly connected to the positions on the outer surface of the outer arc flap 726 close to the second counterweight 710. And brush ends are arranged on the outer protruding end faces of the slotted air guide plates 720 and the full-coverage air guide plates 719, and the brush ends are all attached to one side of the air-permeable bottom groove cover 75.

[0053] Among them, both the configured full-coverage air guide plate 719 and the slotted air guide plate 720 are air guide vane structures in a bent state. The difference is that the full-coverage air guide plate 719 is a whole-piece full-coverage air guide vane, which can rotate better by borrowing wind force under the action of the air duct force on the outside. The slotted air guide plate 720 has a slot opened at the middle position different from a whole-piece full-coverage air guide vane, and this slot is reserved for the guide fan blade frame 724. Because the outer disc housing 71 is in a cylindrical shape as a whole, that is, the air duct entering from the air guide outer slot 74 will also move in an arc shape. In order to provide more wind force for the guide fan blade frame 724 in the middle, the slotted air guide plate 720 is configured. And in order for the air duct in the whole system to pass through smoothly, air-permeable openings are also provided on the surface of the partition plate 78 in the middle of each cylindrical housing 77, so that the air duct entering through the air guide outer slot 74 can pass through smoothly, forming a relatively stable air duct path. The brush ends arranged on the outer protruding end faces of the slotted air guide plates 720 and the full-coverage air guide plates 719 are to clean the openings on one side of the air-permeable bottom groove cover 75 under the rotation of the cylindrical housing 77 to ensure the stability of the air duct path.

[0054] AsFigures 1 to 9 As shown, magnetic attraction plates 712 are fixedly installed at positions on the outer surface of the cylindrical casing 77 where the two first counterweight blocks 717 are flush. Infrared external spotlights 713 are fixedly installed on the sides of the magnetic attraction plates 712. A limiting module 76 aligned with the magnetic attraction plate 712 in the horizontal state of the partition plate 78 is also fixedly installed at the side end position of the air-permeable bottom groove cover 75 away from the air guiding outer notch 74. The limiting module 76 includes an electromagnetic attraction block 761, and an infrared detection block 762 is fixedly installed on the side of the electromagnetic attraction block 761.

[0055] Among them, the configured magnetic attraction plate 712, as the name implies, is a plate with magnetic attraction performance, used for adsorbing with the electromagnetic performance of the electromagnetic attraction block 761. The electromagnetic attraction block 761 is a plate structure in the prior art that can control its magnetic attraction state through electronic control. The configured infrared detection block 762 is an electronic control device in the prior art that can identify infrared rays and perform servo processing. In this limiting module 76, it is a component acting as an electronic control switch. That is, when the infrared external spotlights 713 on both sides of the partition plate 78 shine on the detection block on the outer surface of the infrared detection block 762, the detection block can detect the infrared external spotlights 713. In the horizontal state of the partition plate 78, the configured infrared external spotlights 713 can shine on the infrared detection block 762, causing the infrared detection block 762 to open the electromagnetic attraction block 761 to adsorb the magnetic attraction plate 712 on this side, so as to fix and limit the cylindrical casing 77, and keep the cylindrical casing 77 in a non-rotating state at this position.

[0056] As Figures 1 to 9 As shown, the present invention also provides an axial flow blower, which is composed of an asynchronous induction motor 4 and an impeller fan 5 at the output end of the asynchronous induction motor 4. The axial flow air duct assembly is installed outside the axial flow blower through a cross beam frame 3. A groove opening heat conducting sleeve 61 is also fixedly installed on the outer surface of the asynchronous induction motor 4. The heat conducting mechanism 6 includes a heat preservation outer cylindrical sleeve 62 fixedly installed on the outer surface of the groove opening heat conducting sleeve 61. A group of first reserved sleeve openings 63 are provided at positions on the outer edge surface of the heat preservation outer cylindrical sleeve 62 where each side outer disc casing 71 is flush. A heat preservation outer extension sleeve 64 is fixedly connected to the outside of each first reserved sleeve opening 63, and the outer extending ends of the heat preservation outer extension sleeves 64 extend into the air guiding outer notches 74 on the same side.

[0057] As Figures 1 to 9As shown, the heat conduction mechanism 6 further includes an externally extending heat conduction rod 66 sleeved in each side heat preservation outer extension sleeve 64. And on one side end of each side externally extending heat conduction rod 66 close to the asynchronous induction motor 4, a heat conduction outer notch sleeve plate 65 is fixedly installed. And the heat conduction outer notch sleeve plates 65 are respectively in corresponding fitting with the notch heat conduction sleeves 61 on the same side. One end of the externally extending heat conduction rod 66 far from the heat conduction outer notch sleeve plate 65 is fixedly installed with an open-thread heat dissipation sleeve head 67. And the open-thread heat dissipation sleeve head 67 is entirely located inside the air guiding outer notch 74.

[0058] Among them, the configured notch heat conduction sleeve 61, the externally extending heat conduction rod 66, the heat conduction outer notch sleeve plate 65, and the open-thread heat dissipation sleeve head 67 are all made of materials with good heat conduction characteristics in the prior art. And the configured heat preservation outer cylindrical sleeve 62 and the heat preservation outer extension sleeve 64 are all made of materials with good heat preservation characteristics in the prior art, which are used to better transfer the heat generated on the outer surface of the asynchronous induction motor 4.

[0059] As Figures 1 to 9 shown, on the outer disc sleeve housing 71, on one side opposite to the air permeable bottom groove cover 75, a first hinge sleeve 72 is fixedly installed. And an outward-turning sealing cover 73 is movably installed through the first hinge sleeve 72. The outward-turning sealing cover 73 is entirely located outside the axial flow fan housing 1.

[0060] Among them, the configured first hinge sleeve 72 is used to provide a movable shaft for the outward-turning sealing cover 73, so that the outward-turning sealing cover 73 can stably turn outwards. And the outward turning of the outward-turning sealing cover 73 can open the outer disc sleeve housing 71, which is convenient for maintaining the cylindrical sleeve housing 77. And as can be known from the above, the outer arc turning plate 726 is also movably hinged, so it can be opened outwards by turning outwards to maintain and process the internal particles.

[0061] As Figures 1 to 9 shown, on the outer surface of the axial flow fan housing 1, an auxiliary supporting hanger 2 is also fixedly installed. The auxiliary supporting hanger 2 is a hanger that can be adjusted in multiple axial directions.

[0062] Among them, the configured auxiliary supporting hanger 2 is used to support and fix the air duct pipes to ensure their stable positions and avoid displacement or damage caused by vibration or external forces.

[0063] The working principle provided by the present invention is as follows:

[0064] When the present invention is used, firstly, the outer disc casing 71 on each side is opened by turning outward the sealing cover 73, and then the cylindrical casing 77 on each side is opened by the outer arc flap 726, and the adsorption particles are poured into the isolation chambers 711 on both sides of the cylindrical casing 77, and then the device is tightened to make each side relatively sealed, and then the device is installed and fixed at a suitable position by using the auxiliary support hanger 2, and the auxiliary support hanger 2 is adjusted so that the air outlet of the outer casing 1 of the axial flow fan is aligned with the area to be treated;

[0065] Then, under the action of the second counterweight block 710 and the first counterweight block 717 on each side of the cylindrical casing 77, the partition plate 78 of the cylindrical casing 77 on each side is aligned with the limiting module 76, and the signal of the infrared external spotlight 713 is received through the infrared detection block 762 of the limiting module 76, and the electromagnetic suction block 761 is turned on to adsorb and fix the magnetic suction plate 712, so that one side of the isolation cavity 711 of the cylindrical casing 77 is located inside the axial flow fan outer casing 1, and the other side is located outside the axial flow fan outer casing 1. The adsorbed particles in the isolation cavity 711 inside the axial flow fan outer casing 1 can cooperate with the air duct generated by the impeller fan 5 at the output end of the asynchronous induction motor 4 to purify and adsorb the air in the area;

[0066] Then, as the adsorption work proceeds, the adsorbed particles in the isolation chamber 711 inside the axial flow fan outer shell 1 will reach the state of adsorption saturation. At this time, the electromagnetic suction block 761 is turned off by the electric control signal, and the adsorption state is released. Under the influence of wind, the cylindrical shell 77 will rotate. When the cylindrical shell 77 is docked again by controlling the blowing state, it is only necessary to configure the infrared external spotlights 713 on both sides of the cylindrical shell 77 with spotlight signals of different frequencies to cooperate with the adsorption effect of the electromagnetic suction block 761 and the magnetic suction plate 712, so as to accurately dock the isolation chambers 711 on both sides. Specifically, the isolation chambers originally inside the axial flow fan outer shell 1 When 711 is in the adsorption saturation state, the isolation chamber 711 on the other side can be switched to replace the saturated isolation chamber 711 with the isolation chamber 711 on the other side. After the process, the saturated isolation chamber 711 is located outside the outer casing 1 of the axial flow fan. At this time, after the cylindrical casing 77 is fixed by the limiting module 76, the asynchronous induction motor 4 can be turned on again to work, so that the heat generated by the impeller fan 5 at the output end of the asynchronous induction motor 4 and the heat generated by the outer surface are introduced into the outer disc casing 71 from the air guide outer notch 74 through the heat conduction mechanism 6, so as to heat the saturated isolation chamber 711 at a high temperature, so as to promote the activity recovery of the adsorption particles in the saturated isolation chamber 711.

[0067] Finally, if the isolation cavities 711 on both sides are saturated and difficult to recover through high temperature, and the efficiency of high temperature recovery is extremely low, the adsorption particles can be replaced by opening the outward sealing cover 73 and the outer arc flap 726 again.
