Description

Technical Field

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

[0002] In modern industry and construction, blade fans are important air handling equipment and are widely used in ventilation, air conditioning and process air handling systems. However, traditional blade fans often face problems of regular maintenance and cleaning during operation, especially due to the accumulation of grease or other dirt due to their structural characteristics, which can significantly affect the operating efficiency and performance of the fan.

[0003] The blades of traditional blade fans are usually fixed on the rotor of the fan by welding or bolting. Although this design is simple and stable, it is very cumbersome and time-consuming to clean and maintain when faced with accumulated dirt. Since blade fans are often installed in high places or in difficult-to-access locations, technicians often need to spend a lot of time and manpower to complete the removal and cleaning of the blades, which not only increases maintenance costs, but also affects the availability and operating efficiency of the equipment.

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

[0005] In view of the deficiencies in the prior art, the present invention provides a blade fan 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 a carrier for mounting a 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] A 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 secured to the interior edge of the second support bracket, the cam being secured to the interior edge of the second support bracket, and the cam being secured to the interior edge of the second support bracket.

[0012] Preferably, the driving assembly includes a driving motor, which is fixedly mounted on the outer surface of the second connecting plate, the output end of the driving motor is fixedly connected to a driving 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, the mounting cylinder is fixedly connected to the outside of the second connecting plate, the interior of the mounting cylinder is slidably connected to a rubber piston, the outside of the rubber piston is fixedly connected to a movable rod, the bottom end of the movable rod passes through the outside of the mounting cylinder and is fixedly connected to a driving plate, the outside of the movable rod is sleeved with a spring, the outside of the mounting cylinder is connected to a second connecting pipe, the outside of the mounting cylinder is also connected to a first connecting pipe, one-way valves are installed inside the second connecting pipe and the first connecting pipe, 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 via a plurality of connecting pipes.

[0014] Preferably, one end of the spring is fixedly connected to the top of the mounting tube, 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 fits 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 which matches 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 inside of the clamping rod.

[0019] Preferably, one end of the first connecting pipe is connected to 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 meshingly 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 moving plate to move synchronously. During the movement of the moving plate, one end of the connecting rod is driven to swing, and under the traction of the connecting rod, the clamping rod is driven to move along the inner wall of the slide slot, thereby separating the clamping rod from the inside of the slot and moving the blades outward. The spline sleeve and the spline shaft are separated from each other, and the removal of the blades is completed at this time. The quick 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 meshing driven bevel gear to rotate, thereby driving synchronous rotation, thereby driving the eccentric wheel to repeatedly swing, and 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 blade when working will enter the interior through the dust hood and the connecting pipe for storage.

[0023] The present invention provides a blade fan that is easy to disassemble and handle. It has the following beneficial effects:

[0024] 1. The present invention realizes the function of quick removal of blades by adding a disassembly assembly component. Since the blade fan will accumulate grease or other dirt during operation, affecting its efficiency and performance, the quick removal of the blades makes regular cleaning and maintenance more convenient, maintains the normal operation of the fan, and prolongs its service life.

[0025] 2. The present invention 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 in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] Example:

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

[0039] A connecting frame 2, which is used to support a carrier for mounting a blade fan;

[0040] Disassembly and assembly components, which are installed on the left and right sides of the connecting frame 2, and are used to quickly install 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 used to be installed on one side of the connecting frame 2 and is used to drive the dust removal assembly;

[0043] The disassembly and assembly component includes 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 arranged on the inner side of the first connecting plate 3, and a mounting bearing 802 is fixedly connected to one end of the blade 9. 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. A mounting frame 801 is fixedly connected to the outer side of the first connecting plate 3, and mounting plates 803 are fixedly connected to the front and rear sides of the mounting frame 801, and mounting plates 803 are provided inside the mounting plate 803. The inner wall of the installation groove is threadedly connected with a fixing rod 804, one end of the fixing rod 804 is rotatably connected with a moving plate 807, the outer surface of the moving plate 807 is rotatably connected with two connecting rods 808, one end of the connecting rod 808 is rotatably connected with a clamping rod 810, the inner wall of the installation groove is provided with a slide groove 809, the inner side of the second connecting plate 5 is fixedly connected with a support plate 811, the inner part of the support plate 811 is installed with a spline shaft 812, the other end of the blade 9 is fixedly connected with a spline sleeve 813, and the outer surfaces of the first connecting plate 3 and the second connecting plate 5 are both installed with a plurality of mounting bolts 1. The longitudinal section of the clamping rod 810 is set to be square, and the clamping rod 810 is slidably connected with the inner wall of the slide 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. The rapid disassembly of the blade 9 makes regular cleaning and maintenance more convenient, thereby 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 clamping slot 805 to complete the installation of the blade 9 of the fan.

[0045] Please refer to the attached Figure 3 - Attachment Figure 5 The driving assembly includes a driving motor 4, which is fixedly mounted on the outer surface of the second connecting plate 5. The output end of the driving motor 4 is fixedly connected to a driving 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, the spline shaft 812 is rotated by starting the drive motor 4, and the blades 9 are driven to rotate synchronously under the action of the spline sleeve 813, 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 refer to the attached Figure 2 , Attachment Figure 4 , Attachment Figure 8 and attached Fig. 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 inside the mounting cylinder 701, and a movable rod 703 is fixedly connected to the outside of the rubber piston 706, and the bottom end of the movable rod 703 passes through the outside of the mounting cylinder 701 and is fixedly connected to the driving plate 704, and a spring 705 is sleeved on the outside of the movable rod 703, and the outside of the mounting cylinder 701 is connected to the second connecting pipe 707, and the outside of the mounting cylinder 701 is also connected to the first connecting pipe 702, and the second connecting pipe 707 and the first connecting pipe 702 are installed with a one-way valve 708, and the outside of the connecting frame 2 is fixedly connected to the filter box 711, and the upper surface of the filter box 711 is connected to the dust cover 709 through a plurality of connecting pipes 710. The outer surface of the driving plate 704 fits 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 concave part 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 tube 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 tube 701 is in a negative pressure state, so that the dust adhering to the outer surface of the blade 9 when working enters the interior of the filter box 711 through the dust 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 be closed, and the one-way valve 708 located at the second connecting pipe 707 will be opened, and the air inside the installation cylinder 701 will be sprayed out from the second connecting pipe 707.

[0049] Please refer to the attached Figure 8 - Attachment Fig. 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 refer to 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 refer to 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 engaged with the inside of the card rod 810 .

[0054] Specifically, the clamping rod 810 is firmly clamped into the clamping slot 805, so that the stability of the square plate 806 during the installation process can be ensured.

[0055] Please refer to 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 with 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 refer to the attached Figure 3 The outer side of the driven bevel gear 602 is meshedly connected 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 the blades is realized. Since the blade fan will accumulate grease or other dirt during operation, affecting its efficiency and performance. Quick removal of the blades makes regular cleaning and maintenance more convenient, maintaining the normal operation of the fan and extending its service life. By adding a dust removal component, these dust particles can be effectively captured and filtered, thereby significantly improving the air quality, and 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.
