Description

Technical Field

[0001] This utility model relates to the field of air filter technology, and in particular to an air filter for dust removal and purification. Background Technology

[0002] An air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It purifies the air with low dust content and then sends it into the room to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms.

[0003] As shown in the reference case "A Novel Combined Filter for Dust Removal and Air Purification" (Announcement No. CN216320713U), the filter element can be firmly connected through the cooperation between the movable block and the movable hook. The filter element is made of non-woven fabric, which has stable material quality and large dust holding capacity, and can adsorb larger dust particles in the air. At the same time, the filter cotton is made of activated carbon, which can perform a second filtration of the air and remove odors.

[0004] While existing filters use multiple cartridges for secondary filtration to improve air purification, these cartridges are typically installed inside the filter via clips, threads, or nested structures. Replacing the cartridges requires disassembling the housing or loosening multiple connectors, making the process cumbersome and inconvenient for daily maintenance and quick replacement.

[0005] Therefore, an air filter for dust removal and purification is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dust removal and purification air filter to solve the above problems. It improves the air purification effect by using multiple filter elements for secondary filtration. However, filter elements are usually installed inside the filter by snaps, threads or nesting structures. When replacing the filter element, it is necessary to disassemble the housing or loosen multiple connecting parts. The operation steps are cumbersome and not conducive to daily maintenance and quick replacement.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: an air filter for dust removal and purification, comprising: an air filter with multiple air outlets on its surface, and a suction pump fixedly installed inside the air filter; and a convenient replacement mechanism for conveniently replacing the dust removal filter components, the convenient replacement mechanism being disposed inside the air filter; wherein, the convenient replacement mechanism includes multiple filter elements disposed inside the air filter, replacement components are disposed on the outer sides of the multiple filter elements, and a cleaning component is disposed on one side of the air filter. The replacement components allow for quick disassembly and assembly of the multiple filter elements, enabling replacement without disassembling the entire air filter, significantly improving equipment maintenance efficiency and operational convenience. Simultaneously, the cleaning component allows for easy removal of the air inlet components of the air filter and cleaning of its internal structure, ensuring unobstructed air intake and continuous stable operation of the equipment.

[0008] Preferably, the replacement component includes an air guide frame fixedly installed inside the air filter. The air guide frame is connected to the output end of the suction pump. Multiple filter elements are evenly distributed on both sides of the air guide frame, and both sides of the air guide frame are connected to multiple filter elements on both sides. An installation frame is provided on the outer side of each filter element. The installation frame is fixedly installed inside the air filter. The filter element is slidably connected to the installation frame. In use, multiple filter elements are slidably installed inside the corresponding installation frame. When disassembly is required, the filter element can be pulled out along the installation frame, thereby achieving individual removal and quick replacement without disassembling the air filter housing.

[0009] Preferably, a cover plate is fixedly installed on one side of the air filter. The cover plate is located on one side of multiple mounting frames.

When it is necessary to disassemble the filter element, the cover plate can be opened first to expose the opening end of the mounting frame.

[0010] Preferably, two pull blocks are fixedly installed on the surface of the cover plate. Both pull blocks are set in an arc shape. When removing the cover plate, it can be pulled by the two pull blocks to make the cover plate detach from the air filter along the snap-fit ​​direction. The arc-shaped pull blocks are easy to grip.

[0011] Preferably, a fixing frame is fixedly installed on one side of the air filter, and the fixing frame is located on the other side of the plurality of mounting frames. The fixing frame is provided with a plurality of push plates, which are respectively located on one side of the plurality of filter elements. When the cover is opened, the plurality of push plates can simultaneously push the corresponding filter element outward, so that it slides out of the corresponding mounting frame, and completes the quick removal operation of the filter element.

[0012] Preferably, two springs are fixedly installed on one side of the push plate, and the other end of each spring is fixedly connected to the fixed frame. When the cover is opened, the springs simultaneously squeeze the corresponding push plate to move along the direction of the mounting frame, thereby driving the filter element to slide out of the mounting frame and automatically completing the initial push-out action of the filter element, which facilitates quick removal and replacement of the filter element.

[0013] Preferably, the cleaning assembly includes an air intake frame disposed on the top of the air filter, a limiting frame is fixedly installed inside the air filter, the air intake frame is slidably connected to the limiting frame, and the input end of the suction pump passes through the limiting frame and is connected to the air intake frame. When it is necessary to clean the air intake frame, it can be slidably separated from the limiting frame by moving the air intake frame upward, so that the air intake frame can be removed and its interior can be cleaned. This facilitates the removal of dust and impurities accumulated inside due to long-term operation, ensuring the unobstructed airflow channel and stable filtration efficiency.

[0014] The beneficial effects of this utility model are:

[0015] 1. By replacing components, multiple filter elements can be quickly disassembled and installed, allowing for replacement without disassembling the entire air filter, significantly improving equipment maintenance efficiency and ease of operation. Simultaneously, by cleaning the components, the air filter's intake components can be easily removed and their internal structure cleaned, ensuring unobstructed airflow and continuous stable operation of the equipment.

[0016] 2. When it is necessary to clean the air intake frame, the air intake frame can be moved upwards to slide and separate from the limit frame, and the air intake frame can be removed for cleaning. This facilitates the removal of dust and impurities accumulated inside due to long-term operation, ensuring the smooth flow of air and the stability of filtration efficiency.

[0024] In practical implementation: such as Figure 1-5 As shown, an air filter for dust removal and purification includes: an air filter 1 with multiple air outlets 2 on its surface and a suction pump 21 fixedly installed inside the air filter 1; and a convenient replacement mechanism 3, which is located inside the air filter 1 for convenient replacement of the dust removal filter components. The convenient replacement mechanism 3 includes multiple filter elements 31 located inside the air filter 1, replacement components 32 on the outer sides of the multiple filter elements 31, and a cleaning component 33 on one side of the air filter 1. After a period of use, the multiple filter elements 31 can be quickly disassembled and reassembled using the replacement components 32, allowing replacement of the filter elements 31 without disassembling the entire air filter 1, significantly improving the maintenance efficiency and ease of operation. Simultaneously, the air inlet components of the air filter 1 can be easily removed using the cleaning component 33 for cleaning, ensuring unobstructed airflow and continuous stable operation of the equipment.

[0025] Air filter 1, as a device for dust removal and air purification, is typically composed of a housing, an air inlet, an air outlet 2, and internal filter components. Replacement components 32 and cleaning components 33 are both located inside air filter 1, without changing the original control logic and external interface layout of the device. Therefore, the ease of maintenance of the device is improved without affecting the normal operation of the device.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the replacement component 32 includes an air guide frame 321 fixedly installed inside the air filter 1. The air guide frame 321 is connected to the output end of the suction pump 21.

An installation frame 322 is provided on the outer side of the filter element 31. The installation frame 322 is fixedly installed inside the air filter 1. The filter element 31 is slidably connected to the installation frame 322. In use, multiple filter elements 31 are slidably installed inside the corresponding installation frame 322. When disassembly is required, the filter element 31 can be pulled to slide out along the installation frame 322, thereby realizing individual removal and quick replacement without disassembling the housing of the air filter 1. A cover plate 323 is fixedly installed on one side of the air filter 1. The cover plate 323 is provided on multiple installation frames. On one side of 322, a rubber sealing strip is provided on the inner periphery of the cover plate 323 to ensure a tight fit with the housing of the air filter 1 when closed, preventing unfiltered air leakage. The cover plate 323 is connected to the air filter 1 via a snap-fit ​​structure. The cover plate 323 is used to seal the installation area of ​​the filter element 31. When the filter element 31 needs to be removed, the cover plate 323 can be opened first to expose the opening end of the mounting frame 322. Then, the filter element 31 can be pulled out along the slide direction of the mounting frame 322 through the sliding connection structure, realizing the quick removal and replacement of the filter element 31. Two pull blocks 324 are fixedly installed on the surface of the cover plate 323. Both pull blocks 324 are set in an arc shape. When removing the cover plate 323, it can be pulled by the two pull blocks 324 to make the cover plate 323 detach from the air filter 1 along the snap-fit ​​direction. The arc-shaped pull blocks 324 are easy to grip.

[0027] A fixed frame 325 is fixedly installed on one side of the air filter 1. The fixed frame 325 is located on the other side of multiple mounting frames 322. Multiple push plates 326 are provided inside the fixed frame 325. The multiple push plates 326 are located on one side of multiple filter elements 31 respectively. The multiple push plates 326 are respectively set on the tail end side of multiple filter elements 31. When the cover plate 323 is opened, the multiple push plates 326 can push the corresponding filter element 31 outward simultaneously, so that it slides out of the corresponding mounting frame 322, completing the quick removal operation of the filter element 31. Two springs 327 are fixedly installed on one side of the push plate 326. The other end of the two springs 327 are fixedly connected to the fixed frame 325. When the cover plate 323 is opened, the springs 327 simultaneously squeeze the corresponding push plate 326 to move along the direction of the mounting frame 322, thereby driving the filter element 31 to slide out of the mounting frame 322, automatically completing the initial push action of the filter element 31, which facilitates quick removal and replacement of the filter element 31.

[0028] like Figure 2 and Figure 5As shown, the cleaning component 33 includes an air intake frame 331 disposed on the top of the air filter 1. A limiting frame 332 is fixedly installed inside the air filter 1. The air intake frame 331 is slidably connected to the limiting frame 332. The input end of the suction pump 21 passes through the limiting frame 332 and is connected to the air intake frame 331. When it is necessary to clean the air intake frame 331, it can be moved upward to slide and separate from the limiting frame 332, so that the air intake frame 331 can be removed and its interior can be cleaned. This facilitates the removal of dust and impurities accumulated inside due to long-term operation, ensuring the smooth flow of the intake airflow channel and the stability of the filtration efficiency.

[0029] In use, the cover plate 323 is used to seal the installation area of ​​the filter element 31. When the filter element 31 needs to be disassembled, the cover plate 323 can be opened first to expose the opening end of the mounting frame 322. When the cover plate 323 is opened, the spring 327 simultaneously squeezes the corresponding push plate 326 to move along the direction of the mounting frame 322, thereby driving the filter element 31 to slide out of the mounting frame 322, automatically completing the initial push-out action of the filter element 31, which facilitates quick removal and replacement of the filter element 31. The filter element 31 can be replaced without disassembling the entire air filter 1, which significantly improves the maintenance efficiency and operation convenience of the equipment. When the air intake frame 331 needs to be cleaned, it can be moved upward to slide and separate from the limiting frame 332, so that the air intake frame 331 can be removed and its interior can be cleaned to remove dust and impurities accumulated inside due to long-term operation, ensuring the smooth flow of the intake airflow channel and the stability of the filtration efficiency.
