Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically to an axial flow cooling fan. Background Technology

[0002] Axial flow fans, as indispensable key equipment in industrial and mining enterprises, are widely used in mining, petroleum, chemical and other fields. Their core function is to provide efficient heat dissipation solutions for large main motors. These fans have a unique design, with the motor and fan blades cleverly integrated into a cylindrical structure. This not only simplifies the installation process but also significantly improves ventilation efficiency, accurately directing airflow to designated areas to meet complex industrial heat dissipation needs.

[0003] However, current axial flow cooling fans face a challenge in filter maintenance: traditional filters mostly rely on screw bolts for fastening. While this design ensures stability, it is rather cumbersome and time-consuming when the filter needs to be disassembled and cleaned regularly due to dust accumulation or blockage.

[0004] Operators need to loosen multiple bolts one by one to disassemble the filter screen, and then reverse the process to reinstall it. The whole process is not only inefficient, but may also increase maintenance costs and affect the continuity of production. Utility Model Content

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0033] like Figures 1-5 As shown, an axial flow cooling fan of this utility model includes:

[0034] Mounting ring 2 is fixedly installed on the left end of the fan body 1, and the end of mounting ring 2 away from the fan body 1 has a mounting groove 21; and

[0035] The filter assembly is located at the end of the mounting ring 2 away from the fan body 1. A mounting block 53 is fixedly installed on the outside of the filter assembly, and the mounting block 53 is installed in conjunction with the mounting groove 21.

[0036] Specifically, through the coordinated arrangement of the fan body 1, mounting ring 2, mounting groove 21, filter assembly, and mounting block 53, the mounting block 53 and mounting groove 21 work together to install the filter assembly directly onto the mounting ring 2. This also facilitates quick disassembly of the filter assembly by operators, thereby improving installation and disassembly efficiency and reducing maintenance costs.

[0037] In some embodiments, the mounting groove 21 includes a guide groove 211 and a limiting groove 212. The guide groove 211 is arranged along the axial direction of the mounting ring 2, and the limiting groove 212 is arranged along the circumferential direction of the mounting ring 2. The right side of the guide groove 211 communicates with the limiting groove 212.

[0038] Specifically, by setting the guide groove 211 and the limiting groove 212, when the mounting ring 2 and the filter assembly need to be installed, the mounting block 53 is aligned with the guide groove 211 and slid into the guide groove 211. Then, the filter assembly is rotated clockwise so that the mounting block 53 enters the limiting groove 212 through the guide groove 211, thereby quickly installing the filter assembly.

[0039] In some embodiments, locking components are symmetrically arranged on the side of the limiting groove 212 away from the guide groove 211. The locking components include a plug post 31 and a spring 32 (compression spring). A receiving groove 33 is symmetrically opened in the limiting groove 212. One end of the plug post 31 is slidably installed in the receiving groove 33. The two ends of the spring 32 are fixedly connected to the end of the plug post 31 and the inner wall of the receiving groove 33, respectively. A plug groove 34 is symmetrically opened on the mounting block 53. The end of the plug post 31 located outside the receiving groove 33 is engaged with the plug groove 34.

[0040] In some embodiments, the end of the plug post 31 located outside the receiving groove 33 is hemispherical, and the plug groove 34 is also a hemispherical groove.

[0041] Specifically, by setting up the plug-in post 31, spring 32, receiving groove 33, and plug-in groove 34, when the mounting block 53 slides to a certain position inside the limiting groove 212, the side wall of the mounting block 53 will abut against the hemispherical end of the plug-in post 31, thereby pushing the plug-in post 31 into the receiving groove 33 and squeezing the spring 32. When the plug-in groove 34 is aligned with the receiving groove 33, the plug-in post 31 is pushed out of the receiving groove 33 under the elastic action of the spring 32 and enters the plug-in groove 34 for insertion, thereby completing the installation work.

[0042] In some embodiments, a sealing block 4 is installed on the guide groove 211.

[0043] Specifically, by setting the sealing block 4, the guide groove 211 can be sealed.

[0044] In some embodiments, there are two of each of the guide groove 211, the limiting groove 212, the sealing block 4, and the locking assembly, and the guide groove 211, the limiting groove 212, the sealing block 4, and the locking assembly are arranged symmetrically.

[0045] Specifically, by setting two guide grooves 211, a limiting groove 212, a sealing block 4, and a locking assembly, a better installation effect can be achieved, thereby improving the stability of the installation.

[0046] In some embodiments, the filter assembly includes a connecting ring 51 and a filter screen 52, the filter screen 52 being mounted inside the connecting ring 51 and the outer side of the connecting ring 51 being fixedly connected to the mounting block 53.

[0047] Specifically, by setting up a connecting ring 51 and a filter screen 52, the connecting ring 51 can easily install the filter screen 52 to the mounting ring 2, while the filter screen 52 can provide protection for the fan body 1.

[0048] In some embodiments, the ends of the connecting ring 51 are symmetrically provided with handles 6, which are arranged in a "C" shape.

[0049] Specifically, by providing a handle 6, the operator can easily rotate the connecting ring 51 using the handle 6, and also easily install and remove the connecting ring 51.

[0050] The method of using this utility model is as follows:

[0051] During disassembly, the operator holds both handles 6 and rotates the connecting ring 51 counterclockwise, causing the mounting block 53 to slide counterclockwise inside the limiting groove 212 and enter the guide groove 211. Then, the operator pulls the connecting ring 51 outward, causing the mounting block 53 to slide out of the guide groove 211, thereby completing the disassembly of the filter screen 52.

[0052] During installation, the operator first aligns the mounting block 53 with the guide groove 211, then slides it into the guide groove 211. Next, the operator rotates the connecting ring 51 clockwise, causing the mounting block 53 to pass through the guide groove 211 and enter the limiting groove 212. When the mounting block 53 slides to a certain position in the limiting groove 212, the side wall of the mounting block 53 will abut against the hemispherical end of the insertion post 31, thereby pushing the insertion post 31 into the receiving groove 33 and compressing the spring 32. When the insertion groove 34 is aligned with the receiving groove 33, the insertion post 31 is pushed out of the receiving groove 33 under the elastic action of the spring 32 and enters the insertion groove 34 for insertion, thus completing the installation work.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
