Description

Technical Field

[0001] An air supply system for air blades relates to the field of wind turbine structural design technology. Background Technology

[0002] Air knives, also known as air blades, are important pieces of equipment used in the deep processing and precision finishing of products. They are widely used in various industries such as automotive, electronics, chemicals, metal processing, packaging, and paper printing. An air knife works by blowing pure compressed gas into its chamber using a blower. The gas is rectified by the air knife, creating a powerful air curtain at its outlet. This air can be used for cleaning, dust removal, drying, and cooling of equipment or product surfaces.

[0003] In the actual operation of an air knife air supply system, the fan, as the core power component, generates a large amount of heat when its internal components, such as the motor and bearings, rotate at high speed. If this heat cannot be dissipated in time, the internal temperature of the fan will continue to rise, which will not only reduce the working efficiency of the motor, but may also accelerate the aging of components, shorten the service life of the fan, and even cause failures such as motor overload and burnout, seriously affecting the stable operation of the system. At the same time, the chassis, as the structure that carries the fan, controller, and other components, also generates heat when the controller inside is working. Traditional air knife air supply systems often lack targeted heat dissipation design, or the heat dissipation structure is simple, relying solely on natural heat dissipation or a single heat dissipation component, which is difficult to meet the heat dissipation requirements of the fan and controller under long-term, high-load operation.

[0004] It is evident that existing fan supply systems suffer from two problems: the large amount of heat generated by internal components such as motors and bearings during high-speed operation cannot be dissipated in a timely manner, and the heat generated by the internal controller during operation cannot be dissipated in a timely manner. There is a lack of targeted heat dissipation design for these two issues. Utility Model Content

[0078] The following detailed description of a wind knife air supply system of the present invention, in conjunction with the accompanying drawings and embodiments thereof, will be provided in further detail.

[0079] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0081] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0083] according to Figures 1-16 As shown, the air knife air supply system includes: a fan 01, which serves as the core power component during operation; a casing 02 that fixes the fan 01; and an air supply pipe 03 that connects the fan 01 to the air knife device 04. The fan 01 has its inlet side extending into and fixedly connected to the casing 02, and its outlet side fixedly connected to the air supply pipe 03. A heat dissipation assembly 1 is fixedly connected inside the fan 01 to dissipate heat generated inside the fan 01 in a timely manner. A heat dissipation mechanism 2 is fixedly connected inside the casing 02 to dissipate heat generated by components such as the controller 3 inside the casing 02 in a timely manner. The heat dissipation assembly 1 dissipates heat inside the fan 01 during operation. Specifically, when the fan 01 is running, gas flows axially from one side of the fan 01 to the other. When the flowing gas passes through the heat dissipation assembly 1, it enters the heat dissipation assembly 1. At this time, the heat generated inside the fan 01 is discharged from one side of the fan 01 along with the gas flow, thus continuously dissipating heat inside the fan 01. The heat dissipation mechanism 2 removes heat from the chassis 02 by the airflow during the operation of the fan 01.

[0084] To allow the heat from the controller 3 to dissipate from the housing 02, the housing 02 includes: a casing 021 primarily serving to fix the fan 01; an air inlet 022 that draws air into the housing 02 as the fan 01 operates; and an exhaust 023 that discharges heat from the fan 01 along with the drawn-in air. Correspondingly, the air inlet 022 and exhaust 023 are located on opposite sides of the casing 021 to provide passageways for the air inlet and exhaust. To improve the efficiency of heat dissipation along with the air inlet, the controller 3 is fixedly connected to the side near the air inlet 022. A heat dissipation mechanism 2 is fixedly connected to both the controller 3 and the air inlet 022, and the exhaust 023 is fixedly connected to the fan 01, so that when the fan 01 operates, the air inlet can be drawn into the housing 021 from outside the air inlet 022. The heat dissipation mechanism 2 carries away the heat from the controller 3 through the airflow generated by the fan 01 during operation.

[0085] To better facilitate the expulsion of heat generated inside the casing 02 by the fan 01, the heat dissipation mechanism 2 includes: a heat sink 21 primarily for dissipating heat generated by the controller 3, and a filter plate 22 for filtering the intake air to prevent foreign objects from being sucked in and damaging the fan 01. The heat sink 21 is fixedly connected to the lower side of the controller 3. When the controller 3 operates, it generates heat, and the heat sink 21 can effectively transfer the heat from the controller 3 to itself. The filter plate 22 is located inside the air inlet 022 and is fixedly connected to the casing 021, which can be a threaded connection or a snap-fit ​​connection. By continuously blowing air over the heat sink 21 while the fan 01 is running, the surface heat is blown away, thereby maintaining the efficiency of heat conduction from the heat sink 21 to the controller 3.

[0086] To increase the heat dissipation efficiency of the fan, the heat dissipation assembly 1 includes a heat dissipation cylinder 11 and a guide plate 12 that fixes the heat dissipation cylinder 11 inside the main housing 4. Multiple guide plates 12 are distributed circumferentially along the heat dissipation cylinder 11, which can enhance the air supply capacity, increase the outlet pressure of the fan, and improve the heat dissipation efficiency. The integral molding of the heat dissipation cylinder 11 and the guide plate 12 can make the connection between the heat dissipation cylinder 11 and the main housing 4 more stable.

[0087] The heat sink 11 is further described below. The heat sink 11 includes a first straight cylindrical part 111 that enhances air delivery capacity and reduces the diffusion loss of the outlet airflow and a first conical part 112 that smoothly guides the airflow. The first straight cylindrical part 111 and the first conical part 112 are integrally formed to ensure a smooth transition at the connection.

[0088] To enable internal communication of the transmission assembly 010, a connecting hole 1121 is provided on the end face of the first tapered portion 112, and a first air inlet hole 1122 is provided circumferentially along the connecting hole 1121 on the end face of the first tapered portion 112, penetrating the end face of the first tapered portion 112. Thus, when gas flows through, it can pass through the first air inlet hole 1122 and flow into the interior of the heat sink 11, thereby carrying away the heat generated by the motor 011 and the main shaft 012 during operation.

[0089] Multiple guide vanes 12 are circumferentially arranged on the first straight cylindrical portion 111 to provide a longer guiding path for the airflow, thereby increasing airflow stability and avoiding airflow turbulence. The guide vanes 12 extend from the end of the first straight cylindrical portion 111 toward the first tapered portion 112, and the outer wall of the first straight cylindrical portion 111 is integrally formed with one side of the guide vanes 12. The other side of the guide vanes 12 is fixedly connected to the inner wall of the main housing 4, for example, by welding.

[0090] In order to improve the connection strength of the heat dissipation component 1 inside the main housing 4, in this specific embodiment, threaded holes are respectively provided on the main housing 4 and the heat dissipation cylinder 11, and screws pass through the threaded holes of the main housing 4 and extend into the threaded holes inside the heat dissipation cylinder 11 for fixed connection.

[0091] In order to form a complete heat dissipation channel, the heat dissipation assembly 1 also includes: a front bearing housing 13 that provides an air inlet channel, a rear bearing housing 14 that provides an air outlet channel, and a thrust rear cover plate 15 near the exhaust port.

[0092] The front bearing housing 13 is fixedly connected to the first tapered portion 112 as a heat dissipation air inlet channel. The rear bearing housing 14 is fixedly connected at both ends to the first straight cylindrical portion 111 and the thrust rear cover plate 15, respectively. The first straight cylindrical portion 111 and the thrust rear cover plate 15 serve as heat dissipation air outlet channels. The front bearing housing 13 is fixedly connected to the first tapered portion 112. Correspondingly, to guide airflow and reduce inlet resistance, the side of the front bearing housing 13 is a tapered surface 131. The connection between the tapered surface 131 and the first tapered portion 112 is an arc-shaped transition to ensure a smooth transition at the connection point.

[0093] To allow one end of the main shaft 012 to extend, a front connecting hole 132 is provided in the middle of the front bearing housing 133, and the front connecting hole 132 passes through both ends of the front bearing housing 13. In order to allow airflow to enter the heat sink 11 when the fan 01 is running, a second air inlet 133 is provided on the tapered surface 131 along the circumference of the front connecting hole 132. The second air inlet 133 passes through the front and rear of the front bearing housing 13, and the second air inlet 133 is connected to the first air inlet 1122. That is, during installation, the second air inlet 133 is aligned with the first air inlet 1122, so that the gas can pass through the second air inlet 133 and the first air inlet 1122 axially. Accordingly, to ensure that the front bearing housing 13 can be threadedly connected to the first tapered portion 112, threaded holes are respectively provided on the end faces of the second air inlet 133 and the first tapered portion 112. The threaded holes are evenly distributed between the air inlets, and the screws pass through the first tapered portion 112 and the front bearing housing 13 to fix the screws. In order to install the other end of the spindle 012, a rear connecting hole 141 is provided in the middle of the rear bearing housing 14, and the rear connecting hole 141 passes through the rear bearing housing 14.

[0094] To allow heat to be expelled with the airflow, a first air inlet slot 142 is provided on the surface of the rear bearing housing 14. A first blind slot 143 is provided between the first air inlet slot 142 and the rear connecting hole 141, and the first blind slot 143 connects the first air inlet slot 142 and the rear connecting hole 141 respectively. When the fan 01 is running, the air inlet holes distributed circumferentially have uneven air inlet pressure due to their different positions, which affects the air inlet efficiency and stability. After the first blind slot 143 connects all the first air inlet slots 142, it can form an internal pressure balance chamber, so that the air inlet pressure of each hole tends to be consistent.

[0095] To facilitate connection, a rear-end limiting hole 144 is provided on the surface of the rear bearing housing 14 of the limiting post 5. The rear-end limiting hole 144 is fixedly connected to one end of the limiting post 5, and the other end of the limiting post 5 is fixedly connected to the thrust rear cover plate 15. The limiting post 5 can further improve the mutual fixation between the rear bearing housing 14 and the thrust rear cover plate 15, and at the same time, limit the thrust plate 014 set between them.

[0096] The thrust rear cover plate 15 is further described below. The thrust rear cover plate 15 includes an end face 151 near the fan exhaust port and an extension 152 connected to the main rear bearing housing 14. The end face 151 and the extension 152 are integrally formed, forming an extension cavity 5152 at the connection between them. The extension cavity 5152 provides installation space for the thrust plate 014. Correspondingly, a thrust connection hole 153 is provided in the middle of the end face 151 to allow the main shaft 012 to extend. The thrust connection hole 153 passes through the end face 151. The extension 152 is fixedly connected to the rear bearing housing 14.

[0097] To allow airflow to exit from the heat sink 11 during fan operation, a second air inlet slot 154 is provided on the surface of the end face 151. A second blind slot 155 is provided between the second air inlet slot 154 and the thrust connection hole 153 near the rear bearing seat 14. The second blind slot 155 connects the second air inlet slot 154 and the thrust connection hole 153. When the fan is running, the circumferentially distributed air inlets cause uneven air pressure due to positional differences, affecting air intake efficiency and stability. The second blind slot 155 connects all the second air inlets 154, forming an internal pressure balance chamber, making the air pressure of each hole more uniform. A thrust limiting hole 156 is provided on the surface of the thrust rear cover plate 15, and one end of the limiting post 5 is fixedly connected to the thrust plate 014 to limit its movement.

[0098] The extension 152 is fixedly connected to the rear bearing housing 14. To ensure that the rear bearing housing 14 can be threadedly connected to the heat sink 11 and the thrust rear cover plate 15 respectively, threaded holes are respectively provided on the end faces of the extension 152, the rear bearing housing 14, and the first straight cylindrical portion 111. The threaded holes pass through the rear bearing housing 14, and the screws pass through the thrust rear cover plate 15 and the rear bearing housing 14 respectively, and extend into the first straight cylindrical portion 111 to be fixed by screws.

[0099] To enable the fan to operate, a transmission assembly 010 is also connected inside the fan 01. The transmission assembly 010 includes: a motor 011 fixedly connected inside the heat sink 11; a main shaft 012 driving the impeller 013 to rotate; the impeller 013; and a thrust plate 014 axially limiting the main shaft 012. The motor 011 is fixedly connected inside the first cylindrical section 111, and the main shaft 012 is located inside the motor 011. Both ends of the main shaft 012 extend out of the front end connection hole 132 and the thrust connection hole 153, respectively, and are fixedly connected inside the heat sink 11. The impeller 013 is fixedly connected to the end of the main shaft 012 near the front end connection hole 132. To ensure a more stable axial flow of the fluid entering the impeller and to avoid uneven flow velocity near the hub, a guide cap is fixedly connected to one side of the impeller 013.

[0100] The thrust plate 014 is located in the extension cavity 5152 and is fixedly connected to the main shaft 012. When the fan 01 is running, the thrust plate 014 can provide axial limit for its main shaft 012 to prevent high pressure from being generated on the back surface of the impeller 013, thereby applying an axial thrust to the left to the rotor.

[0101] On the side near the exhaust section 023, one side of the air supply duct 03 is fixedly connected to the fan 01, and the other side is connected to the air knife device 04. The air supply duct 03 serves as a connection between the fan 01 and the air knife device 04, stably delivering the airflow generated by the fan 01 to the air knife device 04. This ensures that the air knife device 04 receives a continuous and stable air supply, meeting its basic requirements for cleaning, dust removal, drying, and air cooling functions through the air curtain. Since the air supply duct 03 is connected to the air outlet side of the fan 01, and the heat dissipation components 1 inside the fan 01 and the heat dissipation mechanism 2 inside the casing 02 already dissipate heat through airflow, the placement of the ventilation duct 03 does not affect the heat dissipation path of the fan 01 and the casing 02. Simultaneously, the stable airflow transmission keeps the fan 01 operating at high efficiency, indirectly ensuring the stable performance of the heat dissipation system and further improving the long-term reliability of the entire air knife supply system.

[0102] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
