Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, as Figures 1-6As shown, a stainless steel liquid-sealed high-efficiency filter includes an outer frame 10 and a filter frame 20 disposed inside the outer frame 10. Both the outer frame 10 and the filter frame 20 are configured with a "U"-shaped structure. The outer frame 10 serves to protect the filter body 50 and facilitates its installation in a corresponding ventilation position. A liquid tank 30 is formed between the filter frame 20 and the outer frame 10. The liquid tank 30 is filled with gel 40. The use of gel 40 to fill the gap between the outer frame 10 and the filter frame 20 maintains a sealed state, so that when air passes through the filter body 50, the gel 40 absorbs vibration and does not cause air to pass through. Regarding air leakage on the outside of the filter body 50, the filter frame 20 has a filter body 50 inside for filtering air, and a filter duct is formed in the vertical direction relative to the filter frame 20 through the filter body 50. An air outlet 60 and an air inlet 70 are respectively provided on the front and rear sides of the filter duct. The arrow indicates the direction of air flow. Two layers of protective nets 80 are provided inside the filter frame 20. The protective nets 80 are respectively installed on the air outlet surface and air inlet surface on both sides of the filter frame 20. The filter body 50 is placed between the two layers of protective nets 80. The protective nets 80 provide protection and preliminary filtration for the filter body 50, which helps to extend the service life of the filter body 50.

[0030] Among them, such as Figures 1-5 As shown, the outer frame 10 includes an upper frame 11, a lower frame 12, and a side plate 13. The upper frame 11 and the lower frame 12 are provided with bending parts 14 on both the left and right sides. Several screw holes are evenly distributed on the surface of the bending parts 14. The upper frame 11 and the lower frame 12 are connected to the side plate 13 by several blind rivets. The outer frame 10 is made of stainless steel and the joints are fixed with blind rivets, which facilitates disassembly and installation.

[0031] Among them, such as Figure 2 and Figure 3 As shown, the filter body 50 includes a frame 51 and a filter element plate 52. The filter element plate 52 is installed inside the frame 51. The filter element plate 52 is composed of several aluminum foil partitions 521 and glass fiber filter paper 522. Glass fiber has good filtration performance and can effectively intercept fine particles such as dust, pollen, and smoke in the air. It has good chemical stability and high temperature resistance, reducing maintenance costs. The aluminum foil partitions 521 are wavy and are arranged between the glass fiber filter paper 522. The peaks and troughs of the aluminum foil partitions 521 are arranged alternately, dividing the glass fiber filter paper 522 into multiple relatively independent filtration channels, increasing the contact area between the air and the glass fiber filter paper 522.

[0032] Among them, such as Figure 1As shown, sealing strips are provided at the corresponding connection points of the filter frame 20, the frame 51, and the protective mesh 80 to ensure that there are no gaps at the joints between them, thereby preventing air leakage from the joints and making the filter look cleaner and more beautiful. High-strength adhesives or injection molding processes can also be used to form an integrated seamless structure, making it easy to select the appropriate sealing method according to specific needs.

[0033] Among them, such as Figure 1 As shown, both the outer frame 10 and the filter frame 20 are made of stainless steel. Stainless steel has the characteristics of good corrosion resistance, high temperature resistance, good processing performance and excellent resistance to intergranular corrosion. This makes the filter thin, lightweight and neat in appearance, and it is widely used in clean rooms, pharmaceutical factories, food hygiene and other environments that require high cleanliness.

[0034] Among them, such as Figure 1 and Figure 2 As shown, the protective mesh 80 is made of stainless steel, which has good corrosion resistance and permeability, ensuring smooth airflow and maintaining a fresh internal environment, while also protecting the filter body 50.

[0035] Example 2

[0036] The difference from Example 1 is that, as in Example 1, Figures 7-9 As shown, the filter plate 52 also includes an activated carbon fiber filter media plate 523 arranged in an S-shape. The activated carbon fiber filter media plate 523 is composed of several U-shaped bending units, which increases the contact area with air, allowing harmful gases and odors to be more fully adsorbed, thus quickly and effectively improving air quality. An aluminum foil spacer 524 is provided between two adjacent bending units. The end of the activated carbon fiber filter media plate 523 is fixedly connected to the side wall of the frame 51. The aluminum foil spacer 524 can adapt to the complex structure of the activated carbon fiber filter media plate 523. While ensuring the support strength, it also has good chemical stability and heat insulation. It will not react with the components in the air and affect the filtration effect, thus providing protection and extending the service life of the filter plate 52.

[0037] Among them, such as Figure 9 As shown, an anti-detachment component 90 is provided between the outer frame 10 and the filter frame 20 to prevent the jelly adhesive 40 from detaching. The anti-detachment component 90 includes several grooves 91 and protrusions 92. The grooves 91 are evenly distributed on the inner sidewall of the outer frame 10, and the protrusions 92 are evenly distributed on the outer sidewall of the filter frame 20. This prevents the jelly adhesive 40 from detaching from the outer frame 10 after it solidifies. After the jelly adhesive 40 is filled, the contact between the jelly adhesive 40 and the inner and outer frame sidewalls facilitates the positioning of the jelly adhesive 40, achieving a sealing effect on the periphery of the filter body 50. This allows air to pass smoothly through the filter body 50, reducing the probability of air leakage.

[0038] In use, the outer frame 10 is first spliced ​​and installed on the outside of the filter frame 20 using pull rivets. Then, the gap between the outer frame 10 and the filter frame 20 is filled with jelly glue to prevent untreated air from escaping from the gap and increase the structural airtightness. After filling, the air will enter from one end of the air inlet 70, pass through the protective mesh 80, and then come into contact with the glass fiber filter paper 522 in the filter plate 52. With the cooperation of the aluminum foil partition 521, the contact time and area between the air and the glass fiber filter paper 522 are extended. After filtration, the air is discharged from the air outlet 60. The overall structure is relatively simple and easy to maintain.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that cannot be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
