Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an anti-static filter. Background Technology

[0002] Air filters are typically used in the intake system of internal combustion engines to filter the air entering the engine, removing dust, particulate matter, and other impurities, ensuring that clean air mixes with fuel for combustion and improving combustion efficiency.

[0003] Due to the high dust levels in the desert, oil-filtered air conditioners are prone to clogging due to dust buildup, requiring frequent cleaning or replacement. Therefore, heavy-duty vehicles used in the desert typically employ tube-type air conditioners. Air swirls within the filter tube under the influence of swirl vanes, separating air from dust and achieving filtration. Since the filter tubes are generally made of plastic, static electricity can easily accumulate during air swirling. This static electricity causes dust to build up inside the filter tubes, affecting the overall filtration efficiency. Utility Model Content

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this utility model discloses an antistatic filter, including an upper shell 10 and a lower shell 20. The upper shell 10 is provided with an air inlet 11 and an air outlet 12. The upper shell 10 and the lower shell 20 cooperate to form a filter chamber. The filter chamber is provided with a cyclone filter tube 30, an upper perforated plate 40 and a lower perforated plate 50. Multiple cyclone filter tubes 30 are arranged in parallel. The upper ends of the multiple cyclone filter tubes 30 are installed on the upper perforated plate 40 and the lower ends are installed on the lower perforated plate 50. Specifically, the upper perforated plate 40 and the lower perforated plate 50 are provided with multiple mounting holes. The cyclone filter tubes 30 are installed in the mounting holes. The side of the cyclone filter tube 30 is provided with an air inlet. The lower end of the cyclone filter tube 30 is provided with a dust discharge hole. The upper end of the cyclone filter tube 30 is provided with an air outlet. A metal part is provided at the air outlet. In this embodiment, the metal part is the cyclone filter tube 30, and the material of the cyclone filter tube 30 is aluminum. Air entering through inlet 11 enters the air inlet hole on the side of the cyclone filter tube 30. Under the action of the cyclone vane 33, the air forms a cyclone. Dust particles in the air are thrown against the inner wall of the cyclone filter tube 30 by centrifugal force and flow downwards along the inner wall of the cyclone filter tube 30, finally being discharged from the filter through the dust discharge hole. The filtered clean air passes through the air outlet hole at the upper end of the cyclone filter tube 30 and the air outlet 12 of the upper housing 10 and is discharged from the filter. The inclusion of metal components, such as an aluminum cyclone filter tube 30, effectively avoids static electricity generated during the air cyclone process, preventing dust from accumulating inside the cyclone filter tube 30 under the influence of static electricity, thereby ensuring the filtration effect and durability of the filter.

[0025] Furthermore, the cyclone filter tube 30 includes an upper tube 31, a lower tube 32, and a cyclone vane 33. The upper tube 31 is mounted on the lower tube 32, and the cyclone vane 33 is located between the upper tube 31 and the lower tube 32. Specifically, the cyclone vane 33 is circumferentially mounted on the outer wall of the upper tube 31. The upper tube 31 is made of aluminum. Under the action of the cyclone vane 33, air forms a vortex, achieving the separation of air and dust. The aluminum upper tube 31 can effectively avoid the generation of static electricity, ensuring the filtration effect and durability of the filter, improving the service life of the filter, and saving on usage and manufacturing costs.

[0026] In other alternative embodiments, the metal component is the upper perforated plate 40, which is made of aluminum. This prevents dust from accumulating inside the cyclone filter tube 30 under electrostatic effects, thereby significantly improving the filter's filtration efficiency. Furthermore, the aluminum material increases the overall structural strength of the upper perforated plate 40, extending its service life.

[0027] Example 2

[0028] like Figure 5 As shown, the difference from Example 1 is the metal part; the rest is the same as in Example 1.

[0029] In this embodiment, the metal component is a sleeve 60, which is installed at the air outlet of the cyclone filter tube 30. Specifically, the sleeve 60 is a straight tube and is installed on the cyclone filter tube 30 and the upper perforated plate 40. By configuring the sleeve 60, the problem of dust accumulation caused by static electricity during air swirl is effectively solved. As a metal component, the sleeve 60's good conductivity can effectively neutralize static electricity, ensuring the filter's filtration efficiency. Furthermore, the design of the sleeve 60 makes it easy to install and maintain without changing the original structure of the cyclone filter tube 30 and the upper perforated plate 40, reducing processing difficulty and significantly improving the filter's anti-static performance, further enhancing the filter's filtration effect.

[0030] In other alternative embodiments, the sleeve 60 can be a T-shaped tube, with the lower end of the T-shaped tube inserted into the cyclone filter tube 30 and the upper perforated plate 40. This not only increases the contact area between the sleeve 60 and the cyclone filter tube 30 and the upper perforated plate 40, improving the stability of the installation, but also allows the sleeve 60 to form a wider coverage at the air outlet of the cyclone filter tube 30, further enhancing the effect of static electricity neutralization, and facilitating installation and maintenance while reducing the difficulty of processing.

[0031] This invention incorporates a metal component, such as an aluminum cyclone filter tube 30, an upper perforated plate 40, or a sleeve 60, at the air outlet. When the metal component comes into contact with static electricity, the free electrons within it quickly conduct the charge to the entire metal component, preventing localized charge accumulation at the air outlet. This effectively avoids the problem of secondary dust adhesion caused by electrostatic attraction, significantly improving the filter's filtration efficiency, enhancing the overall structural strength of the filter, and increasing its durability and service life.

[0032] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
