Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a high-efficiency air filter. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It purifies the low-dust air and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room. Air filter refers to air filtering device, which is used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. Air filter is mainly divided into air intake pipe, processing body and exhaust pipe.

[0003] When in use, the processing body sucks in air through the intake pipe, and the air is discharged through the intake pipe after being processed by the processing body. In order to prevent larger debris from entering the processing body and increasing the filtering pressure of the processing body, a filter is usually provided at the port of the intake pipe. The filter can isolate debris with larger diameters to reduce the filtering pressure of the processing body. A filter with a larger area can isolate more debris, while a filter with a smaller area is prone to clogging after isolating the same debris. When in use, the diameter of the intake pipe is limited, resulting in a limited filtering area of ​​the filter. The filter's ability to isolate debris is limited, and the frequency of replacing and cleaning the filter is high, which is not convenient for actual use.

[0004] The utility model not only has strong ventilation and uniform air supply, but also can ensure that the air volume can be manually controlled to ensure that the high-efficiency air filter is airtight. Utility Model Content

[0005] The utility model aims to provide a high-efficiency air filter which not only has strong ventilation and uniform air supply, but also can ensure that the air volume can be manually controlled to ensure that the high-efficiency air filter is airtight.

[0006] To achieve the above-mentioned purpose, the utility model provides a high-efficiency air filter, including a pressure stabilizing box, an air regulating valve, a filter body, and a diffuser plate. The air regulating valve is provided at the bottom of the pressure stabilizing box, the filter body is provided at the top of the pressure stabilizing box, the diffuser plate is provided above the filter body, an air inlet is provided on the side of the pressure stabilizing box, a punching plate is provided on the air inlet, the filter body adopts ultra-fine glass fiber filter paper, a circular hole is provided in the middle of the diffuser plate, the diffuser plate is configured to be louver-shaped around, a fixed block is provided inside the pressure stabilizing box, the fixed block places the filter body inside the pressure stabilizing box, and control bearings are provided around the fixed block.

[0007] Preferably, the circular holes on the punching plate are evenly distributed.

[0010] Preferably, the regulating valve is cold plate painted, and the shape of the regulating valve is square.

[0011] Preferably, the number of the control bearings is eight, and two of the control bearings are located on one side of the fixed block.

[0012] Therefore, the utility model adopts a high-efficiency air filter of the above structure, which not only has strong ventilation and uniform air supply, but also can ensure that the air volume can be manually controlled to ensure that the high-efficiency air filter is airtight.

[0021] Embodiment 1

[0022] like Figure 1 As shown, the utility model discloses a high-efficiency air filter. An air regulating valve 2 is provided below a pressure stabilizing box 1 , a filter body 3 is provided above the pressure stabilizing box 1 , and a diffuser plate 4 is provided above the filter body 3 .

[0023] The body of the voltage stabilizer box 1 is made of stainless steel by welding. The voltage stabilizer box 1 made of stainless steel has good corrosion resistance and good polishing performance.

[0024] An air inlet 5 is provided on the side of the pressure stabilizing box 1, and a punching plate 6 is provided on the air inlet 5. The circular holes on the punching plate 6 are evenly distributed to ensure uniform air flow and enhance the efficiency of air flow. The pressure stabilizing box 1 is integrally formed and has a super high sealing degree, which ensures the stability of the pressure stabilizing box 1 and improves the working efficiency of the filter body 3.

[0025] The filter body 3 is made of ultra-fine glass fiber filter paper, the diffuser plate 4 is punched in the middle, and the diffuser plate 4 is surrounded by a louver type. The surface of the diffuser plate 4 is divided into circular holes 9 and louver types 10, which not only divert the air, but also ensure different air flow rates, preventing the air from flowing too fast or unevenly causing blockage.

[0026] The diffuser plate 4 is made of cold plate painted panel, and the regulating valve 2 is made of cold plate painted panel, which has good quality, high dimensional accuracy and low price. The regulating valve 2 is square in shape, which is beneficial to the protection of the regulating valve 2 body and the fixing block 7 is provided inside the pressure stabilizing box 1. The fixing block 7 places the filter body 3 inside the pressure stabilizing box 1, and the fixing block 7 is provided with control bearings 8 around it.

[0027] Therefore, the utility model adopts a high-efficiency air filter of the above structure, which not only has strong ventilation and uniform air supply, but also can ensure that the air volume can be manually controlled to ensure that the high-efficiency air filter is airtight.

[0028] Working principle: air first enters the air inlet 5, and then passes through the regulating valve 2. The regulating valve 2 presses the air into the pressure stabilizing box 1. The filter body 3 is fixed by the fixing block 7 in the pressure stabilizing box 1. The control bearing 8 in the pressure stabilizing box 1 can manually adjust the air volume, forming high-purity air in the filter body 3 to remove impurities in the natural air.

[0029] A punching plate 6 is provided on the air inlet 5 to make the wind path wider after the air enters, the wind speed becomes faster and more uniform, and glass glue is provided on the filter body 3. The filter body 3 is fused with the glass glue, and the diffuser plate 4 ensures that the air flows evenly, speeds up the movement speed of the air, and makes the pressure stabilizing box 1 more sealed, so that the filter body 3 can be better adsorbed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
