Technical Field

[0001] This utility model relates to the field of air dust purification technology, and in particular to an environmental air dust purification device that is easy to clean. Background Technology

[0002] Ambient air dust purification refers to the process of removing suspended particulate matter, dust, smoke, and other pollutants from the air through physical or chemical means to improve air quality, protect human health, and maintain the operating environment of equipment. This technology is widely used in industrial plants, mining areas, construction sites, urban roads, and indoor air purification, and is a key link in environmental protection and occupational health protection. In practical applications, the filter cartridge, as the core component of the dust purification device, directly affects the purification effect and continuous operation capability of the entire system due to its filtration efficiency and operating status.

[0003] Specifically, existing ambient air dust purification devices face significant challenges in daily maintenance and filter cleaning, including inconvenient disassembly, low cleaning efficiency, and long downtime. Most devices use bolts, clamps, or multi-point locking structures to secure the filter cartridges, requiring specialized tools for individual disassembly during cleaning or replacement—a cumbersome, time-consuming, and labor-intensive process. Furthermore, the compact installation of filter cartridges in some devices, with limited space, further complicates manual operation. Therefore, addressing these shortcomings of existing technology, we urgently need an innovative, easy-to-clean ambient air dust purification device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an environmental air dust purification device that is easy to clean, solving the problem that most existing environmental air dust purification devices use bolts, clamps, or multi-point locking structures to fix the filter cartridges, which requires special tools to disassemble them one by one when cleaning or replacing them, making the operation cumbersome, time-consuming, and labor-intensive.

[0005] To achieve the above objectives, this utility model provides an environmental air dust purification device that is easy to clean, including a frame. Several filter cartridges are slidably connected to the inner side of the frame, and a top frame is detachably connected to the top of the frame. A top tube is provided on the inner side of the top frame, and the top end of the top tube penetrates through the top frame. Several sealing sleeves are connected to the bottom of the top tube, and the top ends of all filter cartridges are fixedly connected to connecting pipes. A sealing groove for use with the sealing sleeves is opened on the top of the connecting pipes. A bottom tube is connected to the bottom of the frame, and a fan is fixedly connected to one side of the outer wall of the frame by bolts. The inlet of the fan is connected to one side of the bottom tube, and an installation frame is fixedly connected to the top end of the top tube.

[0006] All filter cartridges are fixedly connected to two sides by fixed plates, and all filter cartridges are fixedly connected to two sides by sliders. All sliders are slidably connected to one side of each fixed plate through sliding grooves.

[0007] The frame has a door that is rotatably connected to its outer side via a hinge.

[0008] One side of the top frame is fixedly connected to an insert plate, and one side of the outer wall of the frame is fixedly connected to a docking frame, with the bottom end of the insert plate penetrating through the docking frame.

[0009] The docking frame has threaded rods on both sides, and one end of the threaded rod passes through one side of the docking frame and the insert plate in sequence.

[0010] The fan inlet is connected to a connecting pipe, and one end of the connecting pipe is connected to one side of the bottom pipe.

[0011] This utility model discloses an easy-to-clean ambient air dust purification device. The main structure is a frame, providing installation space and airflow channels for the filter cartridges. The filter cartridges are slidably connected to the inner side of the frame, using a drawer-type installation method. This solves the problem of inconvenient disassembly and cleaning of filter cartridges in existing technologies, which significantly reduces the overall efficiency of the equipment. It significantly improves the convenience of filter cartridge maintenance, avoiding the complex operation of disassembling multiple bolts or clamps required in traditional equipment, reducing reliance on special tools and manual labor intensity. The top frame is detachably connected to the top of the frame, with a simple and reliable structure that allows for quick opening and closing, providing top operating space for filter cartridge assembly and disassembly. The top pipe is fixed to the inner side of the top frame, serving as a collection channel for clean air. The sealing sleeve connected to its bottom cooperates with the connecting pipe and sealing groove at the top of the filter cartridge to form a reliable sealing connection, ensuring the correct airflow path and preventing short-circuit leakage of unfiltered air. When the top frame is disassembled, the sealing sleeve and the connecting pipe naturally separate, releasing the constraint on the top of the filter cartridge and allowing it to be freely pulled out. This achieves a quick disassembly and assembly maintenance mode, significantly shortening downtime for maintenance and improving equipment operating efficiency. The bottom pipe is located at the bottom of the frame and connects to the fan inlet. Under the action of the fan, a stable airflow is formed, pushing dust-laden air upwards through the filter cartridge for filtration. The fan is fixed to the outer wall of the frame with bolts, ensuring a secure installation and facilitating maintenance. The mounting frame is fixed to the top of the top pipe and is used to connect different types of air collection hoods, enhancing the applicability and on-site adaptability of the equipment. The entire device, through the coordinated design of sliding filter cartridge installation, a detachable top frame, and a quick-connect structure for the sealing sleeve and sealing groove, achieves efficient disassembly and cleaning of the filter cartridge. This effectively avoids problems such as filter cartridge clogging, reduced ventilation, and decreased purification efficiency caused by untimely cleaning, extending the service life of the filter cartridge and reducing maintenance costs.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1-5 , An easy-to-clean ambient air dust purification device includes a frame 1, with several filter cartridges 12 slidably connected to the inner side of the frame 1, and a top frame 3 detachably connected to the top of the frame 1. A top tube 11 is provided on the inner side of the top frame 3, and the top end of the top tube 11 penetrates through the top frame 3. Several sealing sleeves 16 are connected to the bottom of the top tube 11, and a connecting pipe 17 is fixedly connected to the top end of all the filter cartridges 12. A sealing groove 18 for use with the sealing sleeves 16 is opened on the top end of the connecting pipe 17. A bottom tube 8 is connected to the bottom of the frame 1, and a fan 5 is fixedly connected to one side of the outer wall of the frame 1 by bolts. The inlet of the fan 5 is connected to one side of the bottom tube 8. An installation frame 4 is fixedly connected to the top end of the top tube 11.

[0021] When using an easy-to-clean ambient air dust purification device, first place the frame 1 in the area where air purification is needed, such as an industrial workshop, construction site, or near a dust source, ensuring its location is reasonable to achieve optimal airflow coverage; connect and fix different types of dust collection hoods to the mounting frame 4 according to the actual working conditions. The mounting frame 4 is connected to the top of the top pipe 11 by bolts or clips to guide dust-laden air into the purification system; start the fan 5 fixed to one side of the outer wall of the frame 1. The inlet of the fan 5 is connected to the bottom pipe 8 through a pipe. When the fan 5 is running, it forms dust inside the frame 1. A negative pressure airflow system collects dust-laden air from the outside through a dust collection hood and enters the frame 1 through a bottom pipe 8. The air flows upwards within the frame 1 and enters a top pipe 11 located inside the top frame 3. Several sealing sleeves 16 are connected to the bottom of the top pipe 11, each corresponding to the installation position of a filter cartridge 12. The filter cartridge 12 is slidably installed inside the frame 1, with a connecting pipe 17 fixedly connected to its top. A sealing groove 18 is provided on the top of the connecting pipe 17. After the top frame 3 and the top of the frame 1 are detachably connected, the sealing sleeve 16 is inserted into the sealing groove 18, forming an airtight connection to ensure the filter cartridge is airtight. Dusty air must be filtered through filter cartridge 12 before being discharged upwards, achieving effective dust interception and air purification. Clean air filtered through filter cartridge 12 enters the interior through the outer wall of the cartridge, passes through connecting pipe 17 and sealing sleeve 16, enters top pipe 11, and is finally discharged to the external environment. When a large amount of dust accumulates on the surface of filter cartridge 12 after a period of operation, causing increased resistance or requiring regular maintenance, cleaning can be performed: First, disconnect the power supply to fan 5 to ensure safe shutdown. Then, disassemble the top frame 3 from the top of frame 1. This connection method does not require complex tools and can be achieved through quick-release clips and screws. Easy assembly and disassembly can be achieved by using screw threads or simple bolts; during the removal of the top frame 3, the sealing sleeve 16 simultaneously detaches from the sealing groove 18 of the connecting pipe 17, releasing the limiting constraint on the top of the filter cartridge 12; at this time, the filter cartridge 12 only maintains contact with the frame 1 through a sliding connection, and can be directly pulled out one by one from the inside of the frame 1 along the sliding direction to achieve quick disassembly; the removed filter cartridge 12 can be used for backflushing, washing, or replacement of filter elements and other maintenance operations. After cleaning, it is reinserted into the frame 1, and then the top frame 3 is installed and reset so that the sealing sleeve 16 is re-embedded into the sealing groove 18, restoring the airtight connection and completing the entire cleaning process.

[0022] Furthermore, each filter cartridge 12 is fixedly connected to a fixing plate 13 on both sides, and each filter cartridge 12 is fixedly connected to a slider 14 on both sides. Each slider 14 is slidably connected to one side of each fixing plate 13 via a sliding groove 15. During the process of pulling and disassembling the filter cartridge 12 along the inner side of the frame 1, the slider 14 slides synchronously in the sliding groove 15 on one side of the fixing plate 13, forming a stable linear guide structure. This effectively limits the movement trajectory of the filter cartridge 12, preventing it from shifting, shaking, or getting stuck when pulled out or inserted. This ensures that the filter cartridge 12 can complete the disassembly and installation operations smoothly and steadily, improving the stability and efficiency of the maintenance process. At the same time, this structure enhances the overall structural rigidity of the filter cartridge 12, preventing deformation caused by unilateral force.

[0023] Furthermore, a door 2 is hinged to the outer side of the frame 1. When the filter cartridge 12 needs to be cleaned or replaced, the door 2 can be opened to directly contact the filter cartridge 12 inside the frame 1, providing a lateral operation channel. This is especially suitable for installation environments with limited space or inconvenient top operation, making it easy to observe, inspect, or assist in pulling out the filter cartridge 12 from the side, improving the flexibility and accessibility of maintenance. At the same time, when the door 2 is closed, it can enhance the sealing of the frame 1, preventing dusty air from leaking from the side during operation and ensuring the airtight performance of the purification system.

[0024] Furthermore, a plug plate 10 is fixedly connected to one side of the top frame 3, and a mating frame 7 is fixedly connected to one side of the outer wall of the frame 1. The bottom end of the plug plate 10 passes through the mating frame 7. When the top frame 3 is installed on the top of the frame 1, the plug plate 10 is inserted into the mating frame 7 to form a horizontal positioning structure. This ensures that the installation position between the top frame 3 and the frame 1 is accurately aligned, avoiding the sealing sleeve 16 and the mating pipe 17 from failing to properly align due to misalignment. This improves the accuracy and reliability of the installation of the top frame 3 and provides positional assurance for the smooth establishment of subsequent sealing connections.

[0025] Furthermore, threaded rods 9 are provided on both sides of the docking frame 7, and one end of the threaded rod 9 passes through one side of the docking frame 7 and the insert plate 10 in sequence. After the top frame 3 is docked with the docking frame 7 through the insert plate 10, the threaded rod 9 is inserted laterally and passes through the docking frame 7 and the insert plate 10 to achieve mechanical locking between the top frame 3 and the frame 1. This prevents the top frame 3 from loosening or falling off due to vibration or airflow impact during equipment operation, and ensures that the sealing connection between the top pipe 11 and the filter cartridge 12 remains stable, thereby improving the safety and airtightness of the equipment operation.

[0026] Furthermore, the inlet of the fan 5 is connected to a connecting pipe 6, and one end of the connecting pipe 6 is connected to one side of the bottom pipe 8. As a flexible or adjustable transition pipe, the connecting pipe 6 can achieve a reliable connection between the fan 5 and the bottom pipe 8, allowing a certain degree of installation deviation or position adjustment, reducing the assembly accuracy requirements. At the same time, it plays a buffering role when the equipment moves or vibrates, reducing stress transmission, preventing cracking or air leakage at the interface, ensuring the continuity and sealing of the airflow channel, and improving the overall connection reliability and service life of the equipment.

[0027] In summary.

[0028] When using an easy-to-clean ambient air dust purification device, first place the frame 1 in the area requiring air purification, such as an industrial workshop, construction site, or near a dust source, ensuring its location is appropriate for optimal airflow coverage. The door 2, connected to the outside of the frame 1 via a hinge, can be opened when space is limited or lateral operation is required, facilitating observation of the internal structure or assisting with installation and maintenance. Different types of air collection hoods are connected and fixed to the mounting frame 4 at the top of the jacking pipe 11 according to actual working conditions. The mounting frame 4 is connected to the jacking pipe 11 via bolts or clips, guiding dust-laden air into the purification system. Start the fan 5 fixed to one side of the outer wall of the frame 1. The inlet of the fan 5 is connected to one side of the bottom pipe 8 via a connecting pipe 6. The interconnecting pipe 6 acts as a flexible transition component, allowing for a certain range of installation deviations and absorbing vibration stress to ensure the sealing and stability of the airflow channel. When the fan 5 is running, it creates a negative pressure airflow inside the frame 1. Dust-laden air from the outside is collected by the air collection hood and enters the frame 1 through the bottom pipe 8. The air flows upwards within the frame 1 and enters the top pipe 11 located inside the top frame 3. The bottom of the top pipe 11 is connected to several sealing sleeves 16, each corresponding to the installation position of a filter cartridge 12. The filter cartridge 12 is slidably installed inside the frame 1, with fixed plates 13 and sliders 14 fixedly connected to both sides. The slider 14 slides within a groove 15 on one side of the fixed plate 13, forming a stable guiding structure to prevent the filter cartridge 12 from slipping during installation or... During operation, if deviation or shaking occurs; the top of the filter cartridge 12 is fixedly connected to the connecting pipe 17, and the top of the connecting pipe 17 has a sealing groove 18; the top frame 3 is installed by aligning it with the top of the frame 1 from above, and the insert plate 10 fixedly connected to one side of the top frame 3 is inserted into the docking frame 7 fixedly connected to the outer wall of the frame 1 to achieve lateral positioning and ensure that the installation position between the top frame 3 and the frame 1 is accurately aligned; then the threaded rods 9 set on both sides of the docking frame 7 are sequentially passed through the docking frame 7 and the insert plate 10 to complete the mechanical locking and prevent the top frame 3 from loosening or falling off during operation; at this time, the sealing sleeve 16 is inserted into the sealing groove 18 of the connecting pipe 17 to form a reliable airtight connection, ensuring that the dust-laden air must be filtered by the filter cartridge 12 before it can be discharged upwards, achieving effective dust interception and air purification. Air purification: Clean air filtered by filter cartridge 12 enters the interior through the outer wall of filter cartridge 12, passes through connecting pipe 17 and sealing sleeve 16 into top pipe 11, and is finally discharged to the external environment; When a lot of dust accumulates on the surface of filter cartridge 12 after a period of operation, the resistance increases, or regular maintenance is required, cleaning can be performed: First, disconnect the power supply of fan 5 to ensure safe shutdown of the equipment, then remove threaded rod 9, and remove top frame 3 from the top of frame 1 as a whole. During the disassembly process, insert plate 10 is disengaged from connecting frame 7, and sealing sleeve 16 is simultaneously pulled out from sealing groove 18, releasing the limiting constraint on the top of filter cartridge 12; At this time, filter cartridge 12 is only in contact with frame 1 through sliding connection, and can be directly pulled out one by one from the inside of frame 1 along the sliding direction to achieve quick disassembly;The removed filter cartridge 12 can be used for backflushing, washing, or filter replacement. After cleaning, it can be reinserted into the frame 1, and the top frame 3 can be reinstalled. Repeat the above positioning, locking, and sealing steps to complete the entire cleaning process. The frame 1 serves as the main structure, providing installation space and airflow channels for the filter cartridge 12. The filter cartridge 12 is slidably connected to the inside of the frame 1, using a drawer-type installation method. This solves the problem of inconvenient disassembly and cleaning of the filter cartridge 12 in existing technologies, which significantly reduces the overall efficiency of the equipment and greatly improves maintenance convenience. The fixing plates 13, sliders 14, and sliding grooves 15 on both sides of all filter cartridges 12 cooperate to form a stable guiding structure, ensuring smooth and stable operation of the filter cartridge 12 during pulling, preventing jamming or displacement. The door 2 is connected to the frame 1 via hinges, providing a lateral operating channel and enhancing maintenance accessibility, especially suitable for installation environments with limited top space. The top frame 3 and the frame 1 are laterally positioned via the insert plate 10 and the docking frame 7, improving installation accuracy and ensuring accurate docking of the sealing sleeve 16 and the connecting pipe 17. The threaded rod 9 passes through the docking frame 7 and the insert plate 10, achieving mechanical locking of the top frame 3, preventing loosening during operation and ensuring system airtightness. The sealing sleeve 16 cooperates with the sealing groove 18 at the top of the connecting pipe 17, in the top frame 3... After installation, a sealed connection is automatically formed, eliminating the need for additional sealing operations and simplifying the process. The fan 5 is bolted to the outer wall of the frame 1, and its inlet is connected to the bottom pipe 8 via a connecting pipe 6. The connecting pipe 6 has a flexible compensation function, reducing installation accuracy requirements, absorbing vibration, and preventing interface leakage. The mounting frame 4 is fixed to the top of the top pipe 11, supporting quick replacement of various gas collection hoods and improving equipment adaptability. The entire device, through the synergistic effect of multiple structures including the detachable top frame 3, sliding filter cartridge 12, positioning insertion, mechanical locking, and flexible connection, achieves rapid disassembly and efficient cleaning of the filter cartridge 12, avoiding the complex disassembly process of traditional bolt-fastened structures, significantly shortening maintenance time, reducing downtime losses, and improving equipment operating efficiency. Simultaneously, the structural design considers sealing, stability, and operational safety, effectively preventing dust leakage and secondary pollution, extending the service life of the filter cartridge 12, and reducing maintenance costs. It is suitable for continuous operation in high-dust environments such as industrial and construction sites, possessing good practicality, reliability, and application value.
