Description

Technical Field

[0001] This utility model relates to the field of fresh air filtration technology for feed mills, and in particular to a fresh air filtration device for feed mills with a two-stage filtration mechanism. Background Technology

[0002] The prototype of the air filter was a respiratory protective device used by people to protect their breathing. Records show that as early as the first century in Rome, people used masks made of coarse hemp for protection when purifying mercury. Over the long period that followed, air filters made progress, but primarily as respiratory protective devices in hazardous industries, such as the production of harmful chemicals. In 1827, Bupén discovered the laws governing the movement of tiny particles, leading to a deeper understanding of the mechanism of air filtration. The rapid development of air filters was closely related to the development of the electronics industry. In the 1950s, the United States conducted in-depth research on the production process of glass fiber filter paper, which improved and developed air filters. In the 1960s, HEPA filters were introduced; in the 1970s, HEPA filters using fine glass fiber filter paper as the filter medium achieved a filtration efficiency of up to 99.9998% for particles with a diameter of 0.3 micrometers. Since the 1980s, with the emergence of new testing methods, improved evaluation methods, and higher requirements for filtration performance, serious problems with HEPA filters were discovered, leading to the development of the higher-performance ULPA filter.

[0003] Publication (Announcement) No.: CN221570719U discloses a fresh air system filtration device. This technology discloses a fresh air system filtration device, including a housing.

[0020] Specifically, in use, the filter element replacement mechanism 4 is inserted into the installation groove 401 by inserting the filter element installation frame 403 in the filter element replacement mechanism 4 into the installation groove 401. Then, the filter element replacement mechanism 4 is slidably connected to the sliding groove 402 opened on both sides of the inner wall of the installation groove 401 and the sliding block 405 fixedly connected to both sides of the outer wall of the filter element installation frame 403, thereby quickly installing the filter element replacement mechanism 4 on the inner wall of the first filter box 1, thereby achieving rapid replacement of the filtered items.

[0021] In an optional embodiment, the latching mechanism 6 includes a mounting block 601, which is fixedly mounted on the outer wall of the first filter box 1. A rotating rod 602 is rotatably connected inside the mounting block 601. A latching block 603 is fixedly mounted on one end of the rotating rod 602, and a rotating torque 604 is fixedly connected to the other end of the rotating rod 602 away from the latching block 603.

[0022] Specifically, during use, the rotating knob 604 in the buckle mechanism 6 is rotated. This causes the locking block 603, which is fixedly connected to the other end of the rotating knob 604, to rotate. A rotating rod 602 is fixedly connected between the locking block 603 and the rotating knob 604. The rotating rod 602 passes through the interior of the mounting block 601, allowing for quick replacement of the filter screen 5 and preventing clogging caused by excessive dust.

[0023] In an optional embodiment, the second filter mechanism 9 includes a placement groove 901, which is formed on the outer wall of the second filter box 2. A fixing frame 902 is fixedly connected to the inner wall of the second filter box 2. A filter device 903 is movably connected inside the placement groove 901. A second handle 904 is fixedly connected to the outer wall of the filter device 903, and the second handle 904 is disposed on the outer wall of the second filter box 2.

[0024] Specifically, during use, the filter device 903 in the second filter mechanism 9 is inserted into the fixed frame 902 that is fixedly connected to the inner wall of the second filter box 2. A placement groove 901 is provided on the outer wall of the second filter box 2 for installing the filter device 903, thereby performing secondary filtration to ensure the air quality inside.

[0025] In an optional embodiment, a filter screen 5 is movably connected to the outer wall of the first filter box 1, and a snap-fit ​​mechanism 6 is provided on the outer wall of the filter screen 5. An installation block 601 is provided on the outer wall of the filter screen 5, and a locking block 603 is provided on the inner wall of the first filter box 1.

[0027] In an optional embodiment, a dust collection box 7 is movably connected to the lower inner wall of the first filter box 1.

[0028] Working principle: In use, air first passes through the first filter box 1. Inside the first filter box 1, there is a filter element replacement mechanism 4. The filter element mounting frame 403 in the filter element replacement mechanism 4 is inserted into the mounting groove 401. Then, the filter element replacement mechanism 4 is slidably connected to the sliding grooves 402 on both sides of the inner wall of the mounting groove 401 and the sliding blocks 405 fixedly connected to both sides of the outer wall of the filter element mounting frame 403. This allows the filter element replacement mechanism 4 to be quickly installed on the inner wall of the first filter box 1, thereby achieving rapid replacement of the filter cotton and ensuring that the filter cotton can be quickly replaced when it is clogged. After the air passes through the first filter box 1, it passes through the rotating torque 604 in the rotating buckle mechanism 6. This causes the locking block 603, which is fixedly connected to the other end of the rotating torque 604, to rotate. A rotating rod 602 is fixedly connected between the locking block 603 and the rotating torque 604. The rotating rod 602 passes through the interior of the mounting block 601, allowing for quick replacement of the filter screen 5 and preventing blockage due to excessive dust. This ensures that larger particles are not blown into the second filter box 2. A second filtering mechanism 9 is installed inside the second filter box 2. The filter device 903 within the second filtering mechanism 9 is inserted into a fixed frame 902 fixedly connected to the inner wall of the second filter box 2. A placement groove 901 is provided on the outer wall of the second filter box 2 for installing the filter device 903, thus performing secondary filtration to ensure the air quality inside. The above describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
