Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a blade fan that is easy to disassemble. Background Art

[0002] In modern industry and construction, vane fans are essential air handling equipment, widely used in ventilation, air conditioning, and process air handling systems. However, traditional vane fans often face challenges with regular maintenance and cleaning during operation. In particular, their structural characteristics lead to the accumulation of grease and other contaminants, which can significantly affect the fan's operating efficiency and performance.

[0003] The blades of traditional vane blowers are typically fixed to the rotor by welding or bolting. While this design is simple and stable, cleaning and maintenance can be cumbersome and time-consuming due to the accumulation of dirt over time. Because vane blowers are often installed in high or difficult-to-access locations, technicians often need to spend a considerable amount of time and manpower to dismantle and clean the blades, which not only increases maintenance costs but also affects equipment availability and operational efficiency.

[0004] Therefore, those skilled in the art have proposed a blade blower that is easy to disassemble to solve the above problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a blade blower that is easy to disassemble and handle, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a blade fan that is easy to disassemble, comprising:

[0007] A connecting frame, which is used to support the carrier for installing the blade fan;

[0008] Disassembly and assembly components, which are installed on the left and right sides of the connecting frame and are used to quickly install the fan;

[0009] The dust removal component is installed on the outside of the connecting frame and is used to remove dust from the fan;

[0010] A driving assembly, which is installed on one side of the connecting frame and is used to drive the dust removal assembly;

[0011] The cam is fixedly mounted on the outside of the first and second mounting plates, and the cam has a first end fixedly mounted on the outside of the first and second mounting brackets, the cam being arranged to extend out of the way of the first and second mounting brackets.

[0012] Preferably, the drive assembly includes a drive motor, which is fixedly mounted on the outer surface of the second connecting plate, and the output end of the drive motor is fixedly connected to the drive bevel gear, the outer side of the second connecting plate is rotatably connected to a transmission rod, one end of the transmission rod is fixedly connected to an eccentric wheel, and the other end of the transmission rod is fixedly connected to a driven bevel gear.

[0013] Preferably, the dust removal assembly includes a mounting cylinder, which is fixedly connected to the outside of the second connecting plate, and the inside of the mounting cylinder is slidably connected to a rubber piston, and the outside of the rubber piston is fixedly connected to a movable rod, and the bottom end of the movable rod passes through the outside of the mounting cylinder and is fixedly connected to a driving plate, and the outside of the movable rod is sleeved with a spring, and the outside of the mounting cylinder is connected to a second connecting pipe, and the outside of the mounting cylinder is also connected to a first connecting pipe, and a one-way valve is installed inside the second connecting pipe and the first connecting pipe, and the outside of the connecting frame is fixedly connected to a filter box, and the upper surface of the filter box is connected to a dust hood through multiple connecting pipes.

[0014] Preferably, one end of the spring is fixedly connected to the top of the mounting cylinder, and the other end of the spring is fixedly connected to the bottom of the driving plate.

[0015] Preferably, the outer surface of the driving plate is in contact with the upper surface of the eccentric wheel, and the dust cover is fixedly connected to the top of the connecting frame.

[0016] Preferably, the longitudinal section of the clamping rod is set to be square, and the clamping rod is slidably connected to the inner wall of the sliding groove.

[0017] Preferably, the outer surface of the first connecting plate is provided with a mounting hole matching the mounting bearing, and the spline sleeve and the spline shaft are plug-fitted.

[0018] Preferably, one end of the clamping rod matches the shape of the clamping slot, and one end of the clamping slot is clamped with the interior of the clamping rod.

[0019] Preferably, one end of the first connecting pipe is communicated with the upper surface of the filter box, and a filter screen is detachably connected to the inner wall of the filter box.

[0020] Preferably, the outer side of the driven bevel gear is meshedly connected with the outer side of the driving bevel gear.

[0021] Working principle: When the blades need to be removed, the fixing rod is rotated outward, so that the fixing rod moves outward along the mounting plate, thereby driving the movable plate to move synchronously. During the movement of the movable plate, one end of the connecting rod is driven to swing, and under the action of the traction force of the connecting rod, the clamping rod is driven to move along the inner wall of the slide slot, so that the clamping rod is disengaged from the inside of the slot, thus moving the blades outward. The spline sleeve and the spline shaft are separated from each other, and the removal of the blades is now completed. The rapid removal of the blades makes regular cleaning and maintenance more convenient, maintaining the normal operation of the fan and extending its service life.

In addition, when the output end of the driving motor rotates, it will also drive the driving bevel gear to rotate, and further drive the driven bevel gear engaged with it to rotate, thereby driving synchronous rotation, and thus driving the eccentric wheel to swing repeatedly. When the convex part of the eccentric wheel contacts the driving plate, it will drive the movable rod to move upward, and when the concave part of the eccentric wheel contacts the outer surface of the driving plate, it will drive the movable rod to move downward. At this time, under the action of the movable rod, the rubber piston is driven to move upward or downward along the inner wall of the mounting cylinder. When the rubber piston moves downward, the interior of the mounting cylinder will be in a negative pressure state, so that the dust adhering to the outer surface of the blades when working will enter the interior through the dust collection hood and the connecting pipe for storage.

[0023] The utility model provides a blade fan that is easy to disassemble and has the following beneficial effects:

[0024] 1. This utility model adds a disassembly assembly component to achieve the function of quick removal of blades. Since blade fans may accumulate grease or other dirt during operation, affecting their efficiency and performance, the quick removal of blades makes regular cleaning and maintenance more convenient, maintaining the normal operation of the fan and extending its service life.

[0025] 2. The utility model can effectively capture and filter these dust particles by adding a dust removal component, thereby significantly improving the air quality, while preventing dust and particulate matter from accumulating inside the blade fan, resulting in reduced equipment operating efficiency and component damage, thereby greatly improving the service life of the blade fan.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example:

[0038] Please see the attached Figure 1 - Attachment Figure 9 The present invention provides a blade fan that is easy to disassemble, including:

[0039] The connecting frame 2 is used to support the carrier for installing the blade fan;

[0040] Disassembly and assembly components, which are installed on the left and right sides of the connecting frame 2 and are used for quick installation of the fan;

[0041] A dust removal component, which is installed on the outside of the connecting frame 2 and is used to remove dust from the fan;

[0042] A driving assembly, which is installed on one side of the connecting frame 2 and is used to drive the dust removal assembly;

[0043] The disassembly and assembly components include a first connecting plate 3, which is fixedly connected to one side of the connecting frame 2, and a second connecting plate 5 is fixedly connected to the other side of the connecting frame 2. A blade 9 is provided on the inner side of the first connecting plate 3, and one end of the blade 9 is fixedly connected to a mounting bearing 802. A square plate 806 is fixedly connected to the outer side of the mounting bearing 802, and a plurality of slots 805 are provided on the inner side of the square plate 806. The outer side of the first connecting plate 3 is fixedly connected to the mounting frame 801, and the front and rear sides of the mounting frame 801 are fixedly connected to the mounting plate 803, and the interior of the mounting plate 803 is provided with a mounting plate. The mounting groove has a fixed rod 804 threadedly connected to its inner wall. One end of the fixed rod 804 is rotatably connected to a movable plate 807. The outer surface of the movable plate 807 is rotatably connected to two connecting rods 808. One end of the connecting rod 808 is rotatably connected to a clamping rod 810. The inner wall of the mounting groove has a sliding groove 809. A support plate 811 is fixedly connected to the inner side of the second connecting plate 5. A spline shaft 812 is installed inside the support plate 811. The other end of the blade 9 is fixedly connected to a spline sleeve 813. Multiple mounting bolts 1 are installed on the outer surfaces of the first connecting plate 3 and the second connecting plate 5. The clamping rod 810 has a square longitudinal section and is slidably connected to the inner wall of the sliding groove 809.

[0044] Specifically, by rotating the fixing rod 804 outward, the fixing rod 804 will move outward along the mounting plate 803, thereby driving the movable plate 807 to move synchronously. During the movement of the movable plate 807, one end of the connecting rod 808 will be driven to swing, and under the action of the traction force of the connecting rod 808, the clamping rod 810 will be driven to move along the inner wall of the slide groove 809, so that the clamping rod 810 will be disengaged from the inside of the clamping groove 805, and the blade 9 will be moved outward, so that the spline sleeve 813 and the spline shaft 812 are separated from each other. At this time, the disassembly of the blade 9 is completed. By quickly disassembling the blade 9, regular cleaning and maintenance become more convenient, maintaining the normal operation of the fan and extending its service life. Similarly, when blade 9 needs to be installed, the spline shaft 812 at one end of blade 9 is inserted into the spline sleeve 813, and the above steps are repeated to retract the clamping rod 810 into the interior of the mounting plate 803. At this time, the square plate 806 is slid into the interior of the mounting plate 803, and then the fixing rod 804 is rotated. Under the action of the connecting rod 808, the clamping rod 810 is clamped into the slot 805 to complete the installation of the fan blade 9.

[0045] Please see the attached Figure 3 - Attachment Figure 5 The drive assembly includes a drive motor 4, which is fixedly mounted on the outer surface of the second connecting plate 5. The output end of the drive motor 4 is fixedly connected to the drive bevel gear 601. The outer side of the second connecting plate 5 is rotatably connected to a transmission rod 603. One end of the transmission rod 603 is fixedly connected to an eccentric wheel 604, and the other end of the transmission rod 603 is fixedly connected to a driven bevel gear 602.

[0046] Specifically, by starting the drive motor 4, the spline shaft 812 rotates, and under the action of the spline sleeve 813, the blades 9 are driven to rotate synchronously, thereby realizing the rotation of the blades 9 and maintaining the normal operation of the fan. In addition, when the output end of the drive motor 4 rotates, it will also drive the driving bevel gear 601 to rotate, and further drive the meshing driven bevel gear 602 to rotate, thereby driving the transmission rod 603 to rotate synchronously, thereby driving the eccentric wheel 604 to swing repeatedly.

[0047] Please see the attached Figure 2 , Attachment Figure 4 , Attachment Figure 8 and attached Figure 9The dust removal assembly includes a mounting cylinder 701, which is fixedly connected to the outside of the second connecting plate 5. A rubber piston 706 is slidably connected to the inside of the mounting cylinder 701. The outside of the rubber piston 706 is fixedly connected to a movable rod 703. The bottom end of the movable rod 703 passes through the outside of the mounting cylinder 701 and is fixedly connected to the drive plate 704. A spring 705 is sleeved on the outside of the movable rod 703. The outside of the mounting cylinder 701 is connected to a second connecting pipe 707. The outside of the mounting cylinder 701 is also connected to the first connecting pipe 702. One-way valves 708 are installed inside the second connecting pipe 707 and the first connecting pipe 702. A filter box 711 is fixedly connected to the outside of the connecting frame 2. The upper surface of the filter box 711 is connected to a dust cover 709 via multiple connecting pipes 710. The outer surface of the drive plate 704 is in contact with the upper surface of the eccentric wheel 604, and the dust cover 709 is fixedly connected to the top of the connecting frame 2. At the same time, the driving plate 704 will drive the spring 705 to be compressed during the rising process. When the driving plate 704 contacts the recess of the eccentric wheel 604, the driving plate 704 is driven to move downward under the action of the spring 705.

[0048] Specifically, when the convex part of the eccentric wheel 604 contacts the driving plate 704, it will drive the movable rod 703 to move upward. When the concave part of the eccentric wheel 604 contacts the outer surface of the driving plate 704, it will drive the movable rod 703 to move downward. At this time, under the action of the movable rod 703, the rubber piston 706 is driven to move upward or downward along the inner wall of the mounting cylinder 701. When the rubber piston 706 moves downward, the one-way valve 708 located at the first connecting pipe 702 will open, and the one-way valve 708 located at the second connecting pipe 707 will close, so that the interior of the mounting cylinder 701 is in a negative pressure state, so that the dust adhering to the outer surface of the blade 9 when working will enter the interior of the filter box 711 through the dust collection cover 709 and the connecting pipe 710 for storage. When the rubber piston 706 moves upward, the one-way valve 708 located at the first connecting pipe 702 will close, and the one-way valve 708 located at the second connecting pipe 707 will open, and the air inside the installation cylinder 701 will be ejected from the second connecting pipe 707.

[0049] Please see the attached Figure 8 - Attachment Figure 9 One end of the spring 705 is fixedly connected to the top of the mounting tube 701 , and the other end of the spring 705 is fixedly connected to the bottom of the driving plate 704 .

[0050] Specifically, the elastic force of the spring 705 can drive the driving plate 704 to move downward.

[0051] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 6The outer surface of the first connecting plate 3 is provided with a mounting hole that matches the mounting bearing 802, and the spline sleeve 813 and the spline shaft 812 are plug-fitted.

[0052] Specifically, the mounting bearing 802 can be inserted into the interior of the mounting hole. The spline sleeve 813 and the spline shaft 812 are common knowledge to those skilled in the art, wherein the spline shaft 812 can slide along the interior of the spline sleeve 813 .

[0053] Please see the attached Figure 7 One end of the card rod 810 matches the shape of the card slot 805 , and one end of the card slot 805 is locked with the inside of the card rod 810 .

[0054] Specifically, the clamping rod 810 is firmly clamped into the clamping slot 805, thereby ensuring the stability of the square plate 806 during the installation process.

[0055] Please see the attached Figure 2 One end of the first connecting pipe 702 is connected to the upper surface of the filter box 711, and the inner wall of the filter box 711 is detachably connected to a filter screen;

[0056] Specifically, the main function of the filter screen provided inside the filter box 711 is to prevent dust from entering the interior of the installation cylinder 701 through the first connecting pipe 702, thereby ensuring the efficient operation of the dustproof component.

[0057] Please see the attached Figure 3 The outer side of the driven bevel gear 602 is meshed with the outer side of the driving bevel gear 601.

[0058] Specifically, when the driving bevel gear 601 rotates, the driven bevel gear 602 is driven to rotate.

[0059] In summary: By adding a disassembly and assembly component, the function of quick removal of blades is achieved. Since grease or other dirt will accumulate during the operation of the blade blower, affecting its efficiency and performance, the quick removal of the blades makes regular cleaning and maintenance more convenient, maintaining the normal operation of the blower and extending its service life. The addition of a dust removal component can effectively capture and filter these dust particles, thereby significantly improving air quality and preventing dust and particulate matter from accumulating inside the blade blower, which may lead to reduced equipment operating efficiency and component damage, thereby greatly extending the service life of the blade blower.
