Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to a filter device for an air compressor. Background Technology

[0002] An air compressor is a device that compresses air and provides a high-pressure airflow. It is widely used in various fields such as industrial production, machining, medical equipment, and construction. During the air compression process, dust, particulate matter, and other impurities in the air may enter the air compressor, causing wear, blockage, or even damage. Therefore, to ensure the stable operation of an air compressor, a filter device is usually installed at its air inlet to remove impurities and ensure that the air entering the compressor is clean and uncontaminated.

[0003] Most existing filtration devices use fixed filters. When dust accumulates on the filter surface, it can easily cause blockage, affecting airflow and reducing filtration efficiency. This leads to a decline in the performance of the air compressor, requiring regular disassembly and cleaning. The cleaning process is cumbersome and affects the normal operation of the equipment. If cleaning is not done in time, the filter may become overloaded, leading to an increased frequency of filter replacement and increased operating costs. Utility Model Content

[0004] This invention proposes a filtration device for air compressors, which solves the problem that most filtration devices in related technologies are fixed filters. When dust in the air accumulates on the filter surface, it can easily cause blockage, affecting airflow, reducing filtration efficiency, and thus causing a decline in air compressor performance. Therefore, these devices need to be disassembled and cleaned regularly, which is a cumbersome process that affects the normal operation of the equipment. If cleaning is not timely, the filter may become overloaded, leading to an increased frequency of filter replacement and increased operating costs.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figures 1-5 As shown, this embodiment proposes:

[0033] A filtration device for an air compressor, comprising:

[0034] Mounting tube 1, with a cross-shaped mounting bracket 2 fixed inside the mounting tube 1, and a mounting seat 3 inserted on the right side of the mounting bracket 2;

[0035] Filter plate 4, one side of filter plate 4 is attached to the side wall of mounting bracket 2, and filter plate 4 is fixed to mounting base 3 by first nut 5;

[0036] The fan blade assembly 6 is rotatably mounted on the right side of the mounting base 3. One end of the fan blade assembly 6 passes through the mounting base 3 and is fixed to the cleaning assembly 7 by the second nut 8.

[0037] The mounting base 3 has a thread on its outer side at one end that mates with the first nut 5.

[0038] The filter plate 4 has a through-hole 10 that mates with the mounting base 3.

[0039] The right end of the mounting pipe 1 is fixed with a mounting flange 11, and the left end of the mounting pipe 1 is screwed with a protective cover 12. Several fan-shaped through grooves 13 are symmetrically opened on the protective cover 12.

[0040] A dust collection trough 9 is provided on the bottom wall of the installation pipe 1 at the position corresponding to the cleaning component 7.

[0041] In this embodiment, the filter plate 4 is fixed to the mounting frame 2 by the mounting base 3 and the low nut 5. The cleaning component 7 is installed on the fan blade assembly 6 by the second nut 8. The whole assembly is easy to disassemble and assemble, and easy to maintain when the internal structure is damaged. The filter plate 4 is used to filter the gas entering the air compressor, preventing dust from entering the air compressor and damaging the internal parts. The fan blade assembly 6 can rotate when the air compressor drives the air flow, thereby driving the cleaning component 7 to rotate and clean the surface of the filter plate 4, preventing dust from accumulating for a long time and causing the filter plate to become blocked, which would affect the normal operation of the air compressor. The mounting flange 11 allows the device to be installed at the air inlet of the air compressor. The protective cover 12 prevents the internal structure of the mounting pipe 1 from being directly exposed to the outside, providing a certain degree of protection. The dust collection trough 9 allows the dust scraped by the cleaning component 7 to be discharged easily.

[0042] Example 2

[0043] like Figures 4-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0044] The fan blade assembly 6 includes a fan body 61, and a mounting shaft 62 is fixed to one end of the fan body 61.

[0045] The mounting shaft 62 is rotatably connected to the mounting base 3 via a bearing. The mounting base 3 is sleeved on the outside of the mounting shaft 62. A slot 63 is provided at the end of the mounting shaft 62 away from the fan body 61.

[0046] The cleaning component 7 includes a mounting ring 71, which is slidably sleeved on the mounting shaft 62. A locking block 74 that cooperates with the locking groove 63 is fixed inside the mounting ring 71. Mounting plates 72 are fixed on both sides of the mounting ring 71.

[0047] Brush bristles 73 are fixed to the side of the mounting plate 72 near the filter plate 4.

[0048] The outer side of the mounting shaft 62, away from the fan body 61, has a thread that mates with the second nut 8.

[0049] In this embodiment, the fan blade assembly 6 rotates during the airflow driven by the air compressor, thereby driving the cleaning assembly 7 to rotate and clean the surface of the filter plate 4. During the operation of the air compressor, air enters the air inlet of the air compressor through the mounting pipe 1. During the airflow, the fan body 61 rotates, and the fan body 61 rotates through the mounting shaft 62 to drive the cleaning assembly 7 to rotate, thereby cleaning the surface of the filter plate 4.

[0050] During assembly, the mounting base 3, along with the fan blade assembly 6, is first inserted into the right side of the mounting tube 1, allowing the mounting base 3 to pass through the through hole on the mounting frame 2. Then, the filter plate 4 is inserted into the left side of the mounting tube 1, allowing the mounting base 3 to pass through the mounting hole 10 on the filter plate 4. Next, the first nut 5 is installed until the filter plate 4 is tightly fitted against the side wall of the mounting frame 2. Then, the mounting ring 71 is fitted onto the mounting shaft 62, allowing the locking block 74 to engage in the locking groove 63. The second nut 8 is then installed to complete the installation of the cleaning assembly 7. Finally, the protective cover 12 is screwed onto the left side of the mounting tube 1, and the mounting tube 1 is installed at the air inlet of the air compressor using the mounting flange 11 and bolts.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
