Description

Technical Field

[0001] The utility model relates to the technical field of industrial fans, in particular to a large-scale disc-type motor industrial fan. Background Art

[0002] Industrial fans can most efficiently promote the movement of large amounts of air, generate large air volumes, and form a moving, circulating airflow field in the space. They can effectively regulate the problem of air circulation in industrial production workshops. Since the speed of industrial fans is generally around 50 rpm, which is a low-speed operation, it just happens to bring into play the characteristics of disc motors, so industrial fans using butterfly motors are widely used.

[0003] According to the large disc motor industrial fan disclosed in Chinese patent announcement number CN219691852U, the patent can shake off the dust on protective shell one and protective shell two by setting a vibration structure and a cleaning structure, and then further clean the protective shell one and protective shell two through the cooperation of brush one and brush two, so that the blown wind is cleaner. However, the patent still has certain shortcomings in actual use. Most of the dust adsorbed on the fan is adsorbed by static electricity generated by the friction between the rotating blades and the air, and the dust adsorbed by static electricity is difficult to fall off under vibration, resulting in the patent being unable to block and clean the adsorbed dust during the normal operation of the fan, and its practicality has room for improvement.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4The utility model provides a technical solution: a large disc-type motor industrial fan, comprising a base 1, a mounting column 2 is fixedly installed on the top of the base 1, and a fan mechanism 300 for blowing air is installed on the top of the mounting column 2; through the coordinated use between the mounting column 2 on the top of the base 1 and the fan mechanism 300, dust can be intercepted on the air inlet path, and the intercepted dust can be easily processed, thereby avoiding dust from being adsorbed on the fan blades through the flowing air, and at the same time, it can also play a certain filtering role on the flowing air, making the blown wind cleaner, and can also introduce the static electricity on the fan blades into the ground by grounding, which plays a role in eliminating static electricity, thereby greatly improving the practicality of the large disc-type motor industrial fan.

[0026] In this embodiment, the fan mechanism 300 is a structure for blocking and cleaning dust.

[0027] like Figure 1 As shown, the fan mechanism 300 includes a shell 4 fixedly connected to the top of the mounting column 2, a dust shielding assembly for blocking dust in the air is installed on the inner side of the shell 4, and a fan assembly for pushing air is installed on the inner side of the shell 4.

[0028] It should be noted that through the coordinated use of the dust shield assembly and the fan assembly, the dust drawn into the air can be effectively blocked, and the blocked dust can also be brushed and cleaned, so that the air intake will not be greatly affected.

[0029] In this embodiment, the dust blocking assembly is a structure for blocking and sweeping away dust.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the dust shield assembly includes four support rods 501 fixed to the inner bottom wall of the outer shell 4, a mounting plate 502 is fixedly connected between the top ends of the four support rods 501, a raising block 503 is fixedly connected to the top of the mounting plate 502, a small driving mechanism 504 is fixedly installed on the top of the raising block 503, a support block 505 is fixedly connected to the top of the mounting plate 502, a driving rod 506 is rotatably connected to one side of the support block 505 through a bearing, a mounting rod 507 is passed through the top of the driving rod 506, a limiting plate 508 is fixedly connected to the outer side of the mounting rod 507, a bolt 509 is threadedly connected to the end of the driving rod 506, a dust shield mesh plate 510 is connected to the back side of the outer shell 4 by screws, and a brush plate 511 is fixedly connected to the bottom end of the mounting rod 507.

[0031] It should be noted that the front and back sides of the housing 4 are both open so that air can flow normally. The end of the driving rod 506 passes through the front side of the support block 505. The output shaft of the small driving mechanism 504 is fixedly connected to the end of the driving rod 506, so that the small driving mechanism 504 can drive the driving rod 506 to rotate. The small driving mechanism 504 can be a small servo motor.

[0032] In addition, the other end of the driving rod 506 passes through the back side of the dust shield mesh 510, and the front side of the brush plate 511 is in contact with the back side of the dust shield mesh 510, so that the driving rod 506 can drive the brush plate 511 to brush and clean the back side of the dust shield mesh 510.

[0033] At the same time, the top of the limiting plate 508 abuts against the bottom of the driving rod 506, and the end of the bolt 509 passes through the back of the mounting rod 507, so that the mounting rod 507 can be stably installed inside the driving rod 506. At the same time, the mounting rod 507 is limited by the action of the bolt 509, thereby completing the connection.

[0034] In this embodiment, the fan assembly is a structure for pushing and outputting air.

[0035] like Figure 2 and Figure 4 As shown, the fan assembly includes a protective shell 601 connected to the front side of the shell 4 by screws, a butterfly motor body 602 is fixedly installed on the top of the mounting plate 502, a transmission shaft 603 is fixedly installed on the output shaft of the butterfly motor body 602, a fan blade 604 is fixedly installed on the outer side of the transmission shaft 603, two fixing rods 605 are fixedly connected to the inner side of the shell 4, a mounting cylinder 606 is fixedly connected between the opposite ends of the two fixing rods 605, two metal bearings 607 are fixedly installed on the inner side of the mounting cylinder 606, a grounding wire 608 is fixedly connected to the outer side of the metal bearing 607, and a wire bundle 609 for binding the two grounding wires 608 is fixedly connected to the bottom of the shell 4.

[0036] It should be noted that the protective shell 601 is a frame with openings on the front and back sides, and evenly distributed partition rods are fixedly connected to the inside of the frame, through which the fan blades 604 can be separated from the outside world. At the same time, a protective net can be set on the inside of the protective shell 601 to improve the safety performance. The outer side of the transmission shaft 603 is fixedly connected to the inner side of the two metal bearings 607, so that the transmission shaft 603 can be rotatably connected to the mounting tube 606 through the two metal bearings 607, and the mounting tube 606 can also support the transmission shaft 603.

[0037] In addition, the end of the grounding wire 608 passes through the inner side of the mounting tube 606, the outer shell 4 and the wire bundle tube 609 in sequence and is connected to the ground. Specifically, the end of the grounding wire 608 can be connected to the ground through a connector such as a screw, or can be wound around a metal part connected to the ground to achieve a grounding effect. At the same time, when the metal bearing 607 rotates, the inner ring rotates and the outer ring is fixed, so static electricity can be conducted and transported through the conductive properties of the metal.

[0038] The working principle of the above embodiment is:

[0039] When the industrial fan is working, the butterfly motor body 602 is started, and the fan blades 604 are driven to rotate through the transmission shaft 603, so that the air on the front side is pushed out. Under the action of negative pressure, the air on the back side will pass through the dust screen 510 and enter the interior of the shell 4, and then be pushed by the fan blades 604. At the same time, the metal bearing 607 can introduce part of the static electricity carried by the outside of the fan blades 604 into the ground through the transmission shaft 603 under the action of the grounding wire 608, which plays a role in eliminating static electricity and further preventing dust absorption. The small driving mechanism 504 is started regularly to drive the driving rod 506 to rotate, so that the brush plate 511 can brush and clean the outside of the dust screen 510, so that the dust attached to it can be brushed off, which plays a cleaning role, and allows the dust screen 510 to filter the passing air normally.

[0040] Compared with the prior art, the large disc motor industrial fan can intercept dust on the air inlet path through the coordinated use of the mounting column 2 on the top of the base 1 and the fan mechanism 300, and can also facilitate the processing of the intercepted dust, thereby avoiding dust from being adsorbed on the fan blades through the flowing air. At the same time, it can also filter the flowing air to make the blown air cleaner, and can also introduce the static electricity on the fan blades into the ground by grounding, thereby eliminating static electricity, thereby greatly improving the practicality of the large disc motor industrial fan and solving the problem that the existing large disc motor industrial fan has poor cleaning power for dust adsorbed by static electricity during operation.

The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
