Description

Technical Field

[0001] This utility model relates to the field of air filtration device technology, and in particular to a self-cleaning air filtration device for air pollution control. Background Technology

[0002] Against the backdrop of increasingly severe environmental pollution, air pollution control has become an important global issue. With the acceleration of industrialization and urbanization, a large amount of waste gas is emitted into the air, posing a serious threat to the ecological environment and human health. Air pollutants are complex in composition, including particulate matter, sulfur dioxide, nitrogen oxides, volatile organic compounds, etc. These pollutants not only lead to a decline in air quality and cause environmental problems such as smog and acid rain, but are also closely related to a variety of health problems such as respiratory diseases and cardiovascular diseases.

[0003] In existing air filtration devices for air pollution control, filter plates widely adopt a slot-nesting fixing method. When installing the filter plate, it is necessary to precisely align the filter plate with the slot to ensure its edges are fully embedded. However, the internal space of the filtration device is often quite narrow, with limited operating space, making it difficult for installers to operate accurately in such an environment. Furthermore, filter plates are typically large and heavy; adjusting their position and successfully embedding them into the slot within a confined space requires considerable physical strength and effort, making the installation process extremely difficult. In addition, slight dimensional deviations or unevenness in the slot during processing further increase the installation difficulty and may even prevent the filter plate from being installed correctly, requiring secondary processing of the slot or replacement of the filter plate, significantly extending the installation time. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning air filtration device for air pollution control.

[0007] Preferably, the fixed abutment assembly includes two push plates symmetrically installed on one side of the rectangular slot.

[0008] Preferably, the pressing assembly includes an L-shaped mounting groove formed within the abutment mounting frame. A spring pressing block is provided at the upper end of the L-shaped mounting groove. A lifting spring is fixedly connected to the spring pressing block. A pressing protrusion is fixedly connected to the bottom end of the lifting spring. A spring pushing block is abutted against the bottom surface of the pressing protrusion. Both the abutting surfaces of the pressing protrusion and the spring pushing block are provided with a 45° bevel. A pressing post is fixedly connected to one side surface of the spring pushing block. A return spring is sleeved on the pressing post.

[0010] Preferably, the toggle locking assembly includes a locking buckle fixed to the top of the push plate, and the mounting housing and the top surface of the abutting mounting frame are provided with locking protrusions corresponding to the locking buckle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the fixed abutment component on one side of the air filter plate and the rectangular slot, and the push plate pushed by multiple push springs, enables the push plate to automatically and tightly abut against the air filter plate, which facilitates quick fixation of the air filter plate, improves installation efficiency and convenience, and thus enables easy installation of the air filter plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a self-cleaning air filtration device for air pollution control, comprising a mounting housing 1 and multiple rectangular slots inside for inserting filter plates 4. Each filter plate 4 has a fixing abutment component mounted on one side of a rectangular slot. Abutment mounting frames 2 are provided between the opposite faces of the multiple filter plates 4. A pressing component is installed in the center of the top surface of the abutment mounting frames 2. A lever locking component 3 is symmetrically provided on both sides of the top surface of each filter plate 4. This constitutes the basic structure of the air filtration device. The components work together to provide a foundation for the installation, fixing, and subsequent operation of the filter plates 4. The mounting housing 1 is made of high-strength engineering plastic and is lightweight. It also possesses excellent corrosion resistance, effectively protecting internal components from external environmental erosion while reducing the overall weight of the device, facilitating installation and transportation. This structural design provides the entire air filtration device with good stability and protection, allowing subsequent components to function effectively. Two symmetrical limiting buckles 8 are provided on both sides of the bottom of the filter plate 4. Corresponding abutment protrusions are provided on the inner wall of the mounting housing 1. Limiting insertion holes 9 are provided at the lower end of the surface of the mounting housing 1 opposite to the filter plate 4, and buckle limiting rods 5 are inserted into the limiting insertion holes 9. This structure achieves secondary fixation of the filter plate 4, improving the stability of the filter plate installation. The limiting buckles 8 and the abutment... The interlocking protrusions restrict the horizontal displacement of the filter plate 4, while the locking limit rod 5 inserts into the limiting hole 9 to prevent the filter plate 4 from loosening vertically. The filter plate 4 is made of a composite material of high-efficiency filter fiber and high-strength skeleton, which ensures both good filtration effect and sufficient structural strength to withstand the impact of gas and the force of the fixing components. This design ensures that the filter plate 4 remains stable during the operation of the device, effectively improving the filtration efficiency and reliability of the filtration device. The fixing abutment component includes two push plates 7 symmetrically installed on one side of the rectangular slot, and multiple push springs 1 are fixed between the push plates 7 and the rectangular slot. 4. Guide telescopic rods are provided between multiple push springs 14, and the guide telescopic rods are connected to the push plate 7 and the rectangular slot. The fixed abutment assembly realizes the automatic fixation of the air filter plate 4, improving the installation efficiency. The push springs 14 provide continuous thrust, making the push plate 7 tightly abut against the air filter plate 4. The guide telescopic rods ensure the stability and straightness of the push plate 7 during movement. The push plate 7 is made of aluminum alloy, which is lightweight and high-strength, not easily deformed, and can effectively transmit the thrust of the spring. With this design, the operator only needs to insert the air filter plate 4 into the rectangular slot, and the fixed abutment assembly can automatically complete the fixing operation, which greatly saves installation time and labor costs.

[0020] In this utility model, the pressing assembly includes an L-shaped mounting groove formed within the abutment mounting frame 2. A spring pressing block 10 is provided at the upper end of the L-shaped mounting groove. A lifting spring is fixedly connected to the spring pressing block 10, and a pressing protrusion is fixedly connected to the bottom end of the lifting spring. A spring pushing block 11 abuts against the bottom surface of the pressing protrusion. Both the abutment surfaces of the pressing protrusion and the spring pushing block 11 are formed at a 45° angle. A pressing post is fixedly connected to one side of the spring pushing block 11, and a return spring is sleeved on the pressing post. The pressing assembly provides a mechanism for disassembling the air filter plate 4. The convenient operation involves pressing the spring-pressing block 10, compressing the lifting spring, and pushing the spring-pushing block 11 at a 45° angle to extend the squeezing column, thereby pushing the air filter plate 4 and disengaging it from other fixed components. Both the spring-pressing block 10 and the spring-pushing block 11 are made of engineering plastic, offering excellent wear resistance and insulation while reducing overall weight. This design simplifies and reduces the effort required to disassemble the air filter plate 4, improving maintenance efficiency. The top surface of the air filter plate 4... Two handles 6 are symmetrically arranged on both sides. The handles 6 facilitate the operation of the air filter plate 4 for the operator to move and install. The handles 6 are made of rubber with a non-slip texture, which not only feels comfortable but also effectively prevents the air filter plate 4 from slipping during operation. This design further improves the convenience of the air filter plate 4 during installation and removal and reduces the difficulty of operation. The toggle locking assembly 3 includes a locking buckle 12 fixed to the top of the push plate 7. The top surface of the mounting housing 1 and the abutment mounting frame 2 are provided with locking protrusions 13 corresponding to the locking buckle 12. The toggle locking assembly 3 is used to fix and unlock the push plate 7, which facilitates the operation of installing and removing the air filter plate 4. The cooperation of the locking buckle 12 and the locking protrusion 13 can lock the position of the push plate 7 when needed, which is convenient for the insertion and removal of the air filter plate 4. The locking buckle 12 and the locking protrusion 13 are both made of stainless steel, which has high strength and corrosion resistance and can ensure long-term stable use. Through this design, the operator can control the position of the push plate 7 more flexibly, which improves the efficiency and convenience of the maintenance of the air filtration device.

[0021] Working Principle: When using this utility model, during the installation of the air filter plate 4, the push plate 7 is first fixed by the locking buckle 12 at its top end to the mounting housing 1 and the locking protrusion 13 on the top surface of the mounting frame 2. At this time, the push plate 7 is positioned close to the rectangular slot. Then, the air filter plate 4 is inserted along the rectangular slot. After insertion, the locking buckle 12 and locking protrusion 13 are released. At this time, the push plate 7 is pushed towards the air filter plate 4 under the action of multiple pushing springs 14. The buckle protrusions on both sides of the bottom end of the air filter plate 4 will slide and abut against the abutment protrusions on the inner wall of the mounting housing 1 under the push of the push plate 7 until the air filter plate 4 reaches the appropriate position. Then, the buckle limiting rod 5 is inserted into the limiting insertion hole 9 opened at the lower end of the opposite side of the mounting housing 1 and the air filter plate 4, completing the secondary fixing of the air filter plate 4. The installation process of the air filter plate 4 is now complete. When it is necessary to disassemble... When removing the air filter plate 4, the push plate 7 is again secured by the locking buckle 12 and the locking protrusion 13. Then, the pressing assembly is operated to press the spring pressing block 10. As the spring pressing block 10 moves downward, it compresses the lifting spring fixed at its bottom and causes the squeezing protrusion to move downward. Since the contact surfaces of the squeezing protrusion and the spring pushing block 11 are both at a 45° angle, the downward movement of the squeezing protrusion will cause the spring pushing block 11 to move forward along the horizontal direction of the L-shaped mounting groove. The squeezing column fixed on one side of the spring pushing block 11 moves forward together with the spring pushing block 11, thereby pushing the air filter plate 4 and causing the snap-fit ​​protrusion at the bottom of the air filter plate 4 to disengage from the contact protrusion. At this time, the operator can use the handles 6 symmetrically arranged on both sides of the top surface of the air filter plate 4 to pull the air filter plate 4 out of the rectangular slot, completing the disassembly of the air filter plate 4 for replacement. The device is now in use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
