Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to an air filtration and dust removal device. Background Technology

[0002] Air filtration and dust removal devices are widely used in many fields, such as cleanrooms and laboratories. They are of great significance for ensuring air quality, normal equipment operation, and personnel health. They can filter solid substances in the air, such as iron filings and sand particles, to prevent them from damaging equipment components and extending equipment life. They play an important role in improving air quality, protecting equipment, and meeting special environmental requirements.

[0003] Existing air filtration and dust removal devices mostly filter impurities and dust from the air through internal filters. However, after prolonged use, dust and impurities can adhere to the surface of the internal filter screen. This requires disassembling multiple bolts to remove and clean the filter screen, making the disassembly process cumbersome and difficult to do quickly. Utility Model Content

[0004] The purpose of this invention is to provide an air filtration and dust removal device to solve the problem mentioned in the background art that the internal filter screen of the air filtration and dust removal device is not easy to remove and clean quickly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air filtration and dust removal device, comprising a housing, an air inlet, a driving fan, an air outlet, and a connecting pipe. The air inlet is provided on one side of the housing, and the driving fan is provided inside the air inlet. The air outlet is provided on the side of the housing away from the air inlet, and the connecting pipe is provided on one side of the air outlet. An anti-clogging mechanism is provided inside the air inlet. The anti-clogging mechanism includes a filter frame and connecting blocks. The filter frame is provided inside the air inlet, and connecting blocks are provided at both ends of the filter frame.

[0006] Preferably, each of the two connecting blocks is provided with a limiting plate inside, and a first pull rod extending to the outside of the connecting block is provided on one side of the limiting plate. A first spring is welded between the limiting plate and the connecting block.

[0007] Preferably, one end of the limiting plate is provided with a locking rod extending into the air inlet, and a locking groove is provided at the end of the air inlet near the locking rod.

[0008] Preferably, the housing is provided with a locking and limiting mechanism extending to the outside. The locking and limiting mechanism includes a docking block, a horizontal plate, an activated carbon plate, a plug-in block, a cavity, a horizontal bar, a moving bar, a vertical bar, a second pull rod, a moving plate, a second spring, and a locking block. The housing is provided with evenly distributed docking blocks.

[0009] Preferably, a horizontal plate is provided at one end of the shell, an activated carbon plate extending into the interior of the docking block is provided at one end of the horizontal plate, and a plug-in block extending into the interior of the shell is provided at one end of the horizontal plate, the plug-in blocks being symmetrically distributed at one end of the horizontal plate.

[0010] Preferably, a cavity is provided inside the housing near the plug-in block, a crossbar is provided inside the cavity, and a movable rod extending into the plug-in block is provided on the surface of the crossbar.

[0011] Preferably, one end of the movable rod is provided with a vertical rod extending to the outside of the housing, and a second pull rod is provided on one end of the housing near the vertical rod.

[0012] Preferably, a movable plate is provided on one side of the second pull rod, and a second spring is welded between the movable plate and the housing. A locking block is provided on the side of the second pull rod away from the movable plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This air filtration and dust removal device, by pinching the two first pull rods together, allows the first pull rods to drive the locking rod to move, and then drives the filter frame into the air inlet. Loosening the first pull rods allows the locking rod to lock with the air inlet. Moreover, the filter frame can be quickly disassembled and cleaned after long-term use, avoiding blockage inside the air inlet. By pulling the second pull rod, and then pulling the vertical rod, the moving rod can be moved. Then, the horizontal plate drives the activated carbon plate into the housing. Subsequently, pulling the vertical rod can drive the moving rod to lock with the plug-in block. Then, pushing the second pull rod can lock it with the moving rod, so that the activated carbon plate can be installed inside the housing, and the activated carbon plate can purify the inhaled air.

[0014] 1. This air filtration and dust removal device, by pinching the two first pull rods together, allows the first pull rods to move the locking rod, which then moves the filter frame into the air inlet. When the filter frame moves to a certain position, the first pull rods are loosened, allowing the locking rod to lock with the air inlet. This allows the filter frame to be quickly installed inside the air inlet. After prolonged use of the filter frame, the two first pull rods can be pinched together to remove the filter frame, allowing for quick disassembly and cleaning, preventing blockage inside the air inlet, and avoiding the need to disassemble multiple bolts. This makes the removal and cleaning of the filter frame more convenient and reduces the labor intensity of construction personnel.

[0015] 2. This air filtration and dust removal device, by pulling the second pull rod, can cause the moving plate to compress the second spring. At the same time, when the second pull rod moves, it can cause the locking block to lock with another reserved slot. Then, pulling the vertical rod can cause the moving rod to move, and then the horizontal plate can cause the activated carbon plate to be inserted into the shell, so that the activated carbon plate can be engaged with the docking block, and the insertion block can be engaged with the shell. Then, pulling the vertical rod can cause the moving rod to lock with the insertion block. Then, pushing the second pull rod can lock the second pull rod with the moving rod, thereby fixing the position of the moving rod, so that the insertion block can be locked relatively stably. This makes the activated carbon plate installed in the shell relatively stable, and can purify the intake air through the installed activated carbon plate, preventing odors in the air from entering the room. Therefore, the air filtration and dust removal device has a good odor removal effect when in use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3It can be seen that this utility model provides a technical solution: an air filtration and dust removal device, including a housing 1, an air inlet 2, a drive fan 3, an air outlet 4, and a connecting pipe 5. An air inlet 2 is provided on one side of the housing 1, and a drive fan 3 is installed inside the air inlet 2. An air outlet 4 is provided on the side of the housing 1 away from the air inlet 2, and a connecting pipe 5 is provided on one side of the air outlet 4. An anti-clogging mechanism 6 is provided inside the air inlet 2, the anti-clogging mechanism 6 including a filter frame 601 and a connecting block 602. There is a filter frame 601, and a connecting block 602 is provided at both ends of the filter frame 601. A limit plate 603 is provided inside the two connecting blocks 602. A first pull rod 604 extending to the outside of the connecting block 602 is provided on one side of the limit plate 603. A first spring 605 is welded between the limit plate 603 and the connecting block 602. A locking rod 606 extending into the air inlet 2 is provided at one end of the limit plate 603. A locking groove 607 is provided at the end of the air inlet 2 near the locking rod 606.

[0023] See Figures 1-3 It can be seen that by pinching the two first pull rods 604 together, the first pull rods 604 can drive the limiting plate 603 to move, so that the limiting plate 603 can squeeze the first spring 605 when it moves, and the limiting plate 603 can drive the locking rod 606 to move when it moves, and then drive the filter frame 601 into the air inlet 2. When the filter frame 601 moves to a certain position, the first pull rod 604 is released, and through the reset effect of the first spring 605, the locking rod 606 can engage with the locking groove 607. The locking rod 606 can be locked to the air inlet 2, allowing the filter frame 601 to be quickly installed inside the air inlet 2. After prolonged use of the filter frame 601, the two first pull rods 604 can be pinched together to remove the filter frame 601, allowing for quick disassembly and cleaning. This avoids blockage inside the air inlet 2 and avoids the need to disassemble multiple bolts, making it more convenient to remove and clean the filter frame 601 when using the air filtration and dust removal device, while also reducing the labor intensity of construction personnel.

[0024] See Figure 1 and Figure 4It is known that the housing 1 is provided with a locking and limiting mechanism 7 extending to the outside. The locking and limiting mechanism 7 includes a docking block 701, a horizontal plate 702, an activated carbon plate 703, a plugging block 704, a cavity 705, a horizontal bar 706, a moving rod 707, a vertical bar 708, a second pull rod 709, a moving rod 707, a vertical bar 708, a second pull rod 709, a moving plate 710, a second spring 711, and a locking block 712. The housing 1 is provided with evenly distributed docking blocks 701. One end of the housing 1 is provided with a horizontal plate 702. One end of the horizontal plate 702 is provided with an activated carbon plate 703 extending into the docking block 701. One end of the horizontal plate 702 is provided with a plugging block 704 extending into the housing 1. 04 is symmetrically distributed at one end of the horizontal plate 702. A cavity 705 is opened inside the housing 1 near the plug-in block 704. A horizontal bar 706 is provided inside the cavity 705. A moving rod 707 extending into the plug-in block 704 is provided on the surface of the horizontal bar 706. A vertical bar 708 extending to the outside of the housing 1 is provided at one end of the moving rod 707. A second pull rod 709 is provided on one end of the housing 1 near the vertical bar 708. A moving plate 710 is provided on one side of the second pull rod 709. A second spring 711 is welded between the moving plate 710 and the housing 1. A locking block 712 is provided on the side of the second pull rod 709 away from the moving plate 710.

[0025] See Figure 1 and Figure 4 It can be seen that by pulling the second lever 709, the second lever 709 can drive the movable plate 710 to move, so that the movable plate 710 can compress the second spring 711 when it moves. At the same time, the second lever 709 can drive the locking block 712 to lock with another reserved slot when it moves. Then, pulling the vertical rod 708 can drive the movable rod 707 to move when it moves, so that the movable rod 707 can slide on the surface of the horizontal rod 706, making the movable rod 707 more stable when it moves. Then, the horizontal plate 702 drives the activated carbon plate 703 to insert into the housing 1, so that the activated carbon plate 703 can engage with the docking block 701, and at the same time, the insertion block 704 can engage with the housing 1. Then, pulling the vertical lever... 708, which enables the movable rod 707 to lock with the plug-in block 704, and then pushes the second pull rod 709, so that the locking block 712 on one side of the second pull rod 709 can be unrestrained, and the compressed second spring 711 can be unrestrained, so that the reset second pull rod 709 can lock with the movable rod 707, thereby fixing the position of the movable rod 707, so that the plug-in block 704 can be locked relatively stably, so that the activated carbon plate 703 can be installed more stably inside the housing 1, and the installed activated carbon plate 703 can purify the intake air, prevent odors in the air from entering the room, so that the air filtration and dust removal device can have a good odor removal effect when in use.

[0026] In summary, air filtration and dust removal devices have wide applications in various fields. By pinching the two first pull rods 604 together, the first pull rods 604 can drive the limiting plate 603 to compress the first spring 605. Furthermore, when the limiting plate 603 moves, it can drive the locking rod 606 to move, thus moving the filter frame 601 into the air inlet 2. When the filter frame 601 moves to a certain position, the first pull rods 604 are released. Through the reset effect of the first spring 605, the locking rod 606 can lock with the air inlet 2, thus... The filter frame 601 can be quickly installed inside the air inlet 2. After prolonged use, the filter frame 601 can be removed by pinching the two first pull rods 604 together, allowing for quick disassembly and cleaning. This avoids blockage inside the air inlet 2 and also avoids the need to remove multiple bolts. This makes it easier to remove and clean the filter frame 601 in the air filtration and dust removal device, and also reduces the labor intensity of construction personnel. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
