Description

Technical Field

[0001] This utility model relates to the field of air filters, specifically a washable corrugated plate air filter. Background Technology

[0002] Washable corrugated plate air filters are air purification devices that use corrugated plates as the core filter element and can be reused through multiple cleanings. Their core design concept is to use the corrugated structure to expand the filtration area, improve air circulation efficiency and dust holding capacity, while the washable feature reduces the frequency of filter replacement and lowers long-term operating costs. With the increasing demand for air purification, these filters are widely used in ventilation systems, air conditioning equipment, and industrial dust removal, especially suitable for scenarios with high dust concentrations or requiring frequent maintenance. Compared with disposable filters, the washable design can significantly reduce solid waste generation, meeting environmental protection and economic requirements, and thus becoming an important alternative to traditional non-renewable filter elements.

[0003] However, traditional washable corrugated plate air filters rely on bolts or glue for assembly and disassembly, making disassembly time-consuming and laborious during cleaning. Repeated disassembly and assembly can also cause frame deformation and seal failure. During cleaning, due to the dense arrangement of corrugated plates and the lack of a directional flushing structure, water flow cannot penetrate deep into the corrugation gaps, resulting in significant dust residue and directly affecting the recovery of filtration efficiency. In addition, in traditional structures, corrugated plates are mostly arranged in a single direction, limiting the filtration area. The rigid contact between the frame and the corrugated plates is prone to wear due to vibration, and the drain holes are easily clogged by impurities washed down, leading to a shortened service life. To address these issues, we have proposed a washable corrugated plate air filter. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4 A washable corrugated plate air filter includes a corner bracket 1, a rubber pad 2, a frame 3, and a frame 5. The frame 5 is inverted "C" shape. The top surfaces of the two vertical plates of the frame 5 are provided with connecting grooves. The frame 3 is movably connected to the frame 5. The frame 3 and the frame 5 together form a complete frame. The rubber pad 2 is fixedly installed on the inner wall of the corner bracket 1. The inner side of the rubber pad 2 fits against the corner edge of the frame. A placement slot is provided inside the frame formed by frame 1 3 and frame 2 5. A connecting support plate 8 is installed in the placement slot, and a corrugated plate assembly is provided on the connecting support plate 8. A connecting component 1 is provided on the first frame 3, and a connecting component 2 is provided on the vertical plate of the second frame 5. The first frame 3 and the second frame 5 are securely connected by the connecting component 1 and the connecting component 2.

[0021] Furthermore, rubber pads 29 are fixedly installed on the four corners of the connecting support plate 8. The rubber pads 29 correspond to the four inner corners of the placement slot of the frame. The rubber pads 29 can prevent the connecting support plate 8 from directly and rigidly contacting the frame during the operation of the device, reduce friction loss caused by equipment vibration or airflow impact, and at the same time use their own elasticity to buffer external forces, maintain the stable position of the corrugated plate assembly in the placement slot, ensure that the filtered airflow passes evenly through the gaps between the corrugated plates, and avoid the local airflow turbulence caused by the shaking of the assembly from affecting the filtration effect.

[0022] Furthermore, the corrugated plate assembly includes a corrugated plate 10, a corrugated plate 11, and a guide strip 12. Multiple corrugated plates 10 are fixedly installed on the plane of the connecting support plate 8, and the corrugated plates 10 are distributed equidistantly along the horizontal axis. A corrugated plate 11 is fixedly installed between every two adjacent corrugated plates 10. Guide strips 12 are provided on the surfaces of both corrugated plates 10 and corrugated plates 11. A gap is left between two adjacent corrugated plates 10 and corrugated plates 11, which increases the filtration area and allows water or air to form turbulence in the gap, enhancing the cleaning effect. During the filtration process, the guide strips 12 can guide the airflow along a specific path, prolonging the contact time between the air and the surface of the corrugated plate and improving the adsorption efficiency of fine particles. The gap between adjacent corrugated plates ensures smooth airflow while reducing wind resistance and avoiding a decrease in airflow efficiency due to dense structure. The corrugated directions of corrugated plate 10 and corrugated plate 21 are opposite.

[0023] Furthermore, the connecting component includes a connecting block 7. The bottom surface of the frame 3 is symmetrically fixedly installed on both sides of the corresponding placement groove. A connecting hole is opened on one side wall of the connecting block 7.

[0024] Furthermore, the connecting component two includes a fixed rod 13, a sliding plate 14, and a spring 17. A sliding hole is provided on one side wall of the two vertical plates of the frame two 5. The fixed rod 13 is slidably connected to the sliding hole. The spring 17 is fixedly installed on the bottom surface of the connecting groove on the frame two 5. The sliding plate 14 is in the shape of a "door". The other end of the spring 17 is fixedly connected to the bottom surface of the horizontal plate of the sliding plate 14. When the connecting block 7 has not yet been inserted into the connecting groove on the frame two 5, the vertical plate of the connecting block 7 blocks the fixed rod 13, preventing it from sliding.

[0025] Furthermore, the connecting block 7 and the connecting groove on the second frame 5 are slidably connected, and the fixing rod 13 and the connecting hole on the connecting block 7 are slidably connected.

[0026] Furthermore, a water inlet hole 4 is provided on the top surface of the frame 3, and multiple water spray nozzles 6 are provided on the top surface of the placement groove of the water inlet hole 4. The water spray nozzles 6 are distributed at equal intervals along the horizontal axis. The water inlet 4 and the spray nozzle 6 are connected by an internal water pipe. The internal water pipe evenly distributes the water flow introduced by the water inlet 4 to each spray nozzle 6, ensuring that each corrugated plate can obtain sufficient flushing water. Each spray nozzle 6 corresponds to a corrugated plate 10 or corrugated plate 11. The equidistant distribution of the spray nozzles 6 corresponds one-to-one with the corrugated plates, so that the water flow accurately covers the surface of the corrugated plates, avoids blind spots in rinsing, ensures that the cleanliness of each area is consistent, and restores the uniformity of filtration performance.

[0027] Furthermore, a guide plate 16 is fixedly installed on the bottom surface of the placement groove on the second frame 5, corresponding to the front of the corrugated plate 10.

[0028] Furthermore, the bottom of the placement groove on the second frame 5 is provided with a water outlet corresponding to the low end of the guide plate 16; A sliding groove is provided on the side wall of frame 2 5 near the bottom, and a filter plate 15 is slidably engaged in the sliding groove; The filter holes on filter plate 15 correspond to the water outlet holes on frame 2 5.

Frame 1 3: Frame 1 3 is the upper part of the frame structure. Together with Frame 2 5, it forms a complete frame. The bottom surface is symmetrically fixed with connecting blocks 7 on both sides of the placement slot. The top surface has water inlet holes 4 and multiple water spray nozzles 6. The installation is achieved by connecting the connecting blocks 7 with the connecting slots of Frame 2 5. The internal water pipe connects the water inlet holes 4 and the water spray nozzles 6, providing a water channel for cleaning. It is one of the core components for support and connection. Water inlet 4: Water inlet 4 is the input channel for cleaning water flow. It is located on the top surface of frame 1 3 and is connected to multiple spray nozzles 6 through an internal water pipe. It can be connected to an external water source to introduce water flow and distribute the water flow to each spray nozzle 6. It provides water source for the directional flushing of corrugated plate 1 10 and corrugated plate 2 11. It is the starting point of the cleaning system and ensures a stable supply of flushing water. Frame 2 5: Frame 2 5 is the lower part of the frame structure, which is inverted "C" shape. The top surface of the two vertical plates has a connecting groove, and the guide plate 16 is fixedly installed in the groove. The side wall near the bottom surface has a sliding groove and a filter plate 15 is snapped in. The vertical plates are equipped with connecting components such as fixing rods 13, which cooperate with the connecting block 7 of frame 1 3 to realize the frame assembly. The bottom structure guides the sewage discharge and is the key part to support the corrugated plate assembly and treat the cleaning sewage. Spray nozzle 6: Spray nozzle 6 is the output structure of cleaning water flow. It is set on the top surface of the placement tank of frame 1 3 and is distributed at equal intervals along the horizontal axis. Each nozzle corresponds to a corrugated plate 1 10 or corrugated plate 2 11. It is connected to the water inlet 4 through the internal water pipe, and sprays water flow in a direction to the surface of the corrugated plate to form a rinsing effect, which enhances the removal effect of dust on the surface of the corrugated plate and improves the cleaning efficiency. Connecting block 7: Connecting block 7 is the connecting component between frame 1 3 and frame 2 5. It is fixed to the bottom surface of frame 1 3 and the corresponding placement slots on both sides. The side wall has a connecting hole, which can be inserted into the connecting slot of frame 2 5. It works with the fixing rod 13 to achieve a stable connection between the frames. When disassembling, it can be separated by pulling out the fixing rod 13. It is the core structure for achieving quick assembly and disassembly of the frame, ensuring the convenience and firmness of the connection. Connecting support plate 8: The connecting support plate 8 is the installation base of the corrugated plate assembly. It is a flat plate structure with multiple corrugated plates 10 and 11 fixedly installed on the plane. Rubber pads 9 are fixed at the four corners. It is placed in the placement groove of the frame and supports the corrugated plate assembly by contacting the inner wall of the frame through the rubber pads 9. It reduces vibration and wear and is a key component to ensure stable installation and uniform distribution of the corrugated plates. Rubber pad 29: Rubber pad 29 is a buffer component that connects the support plate 8. It is fixed at the four corners of the support plate 8 and corresponds to the four inner corners of the frame placement groove. It can reduce the hard contact between the support plate 8 and the frame, buffer the impact force generated by the vibration of the device, avoid wear of the support plate and the frame, and at the same time enhance the stability of the support plate in the frame and prevent displacement. Corrugated plate 10: Corrugated plate 10 is the core filter element. It is fixed on the connecting support plate 8 and is distributed at equal intervals along the horizontal axis. The surface has flow guide patterns 12, which are arranged alternately with corrugated plate 2 11 and the corrugation direction is opposite. The corrugated structure expands the filtration area and increases the dust holding capacity. The flow guide patterns 12, together with the water flow, form turbulence to enhance the cleaning effect. It is a key component for achieving air filtration and efficient cleaning. Corrugated plate 2 11: Corrugated plate 2 11 is the core filter element, fixed between adjacent corrugated plates 1 10. It has flow guide lines 12 on its surface, with the corrugation direction opposite to that of corrugated plate 1 10. Together with corrugated plate 1 10, it forms a filter channel, expanding the filter area. The reverse corrugated structure causes turbulence in the airflow and water flow, enhancing the filtration effect and dust removal ability, and improving the overall filtration and cleaning performance.

[0030] Guide lines 12: Guide lines 12 are auxiliary cleaning structures on the surface of corrugated plates. They are patterns formed on the surfaces of corrugated plates 10 and 11. They can guide the cleaning water flow along a specific path to form a spiral scouring force, which breaks the surface tension of dust adhesion, making the dust easier to fall off. At the same time, they enhance the turbulence effect of the water flow in the corrugation gaps and improve the thoroughness of cleaning. Fixed rod 13: Fixed rod 13 is the locking component for the frame connection. It is slidably connected in the sliding hole of the vertical plate of frame 2 5. It can be slidably connected with the connecting hole on the connecting block 7. Under the action of spring 17 and sliding plate 14, it is locked into the connecting hole to realize the stable connection between frame 1 3 and frame 2 5. When pulled, it can be disassembled from the connecting hole. It is the core component of the connecting component 2. Sliding plate 14: Sliding plate 14 is an auxiliary component of connecting component two. It is shaped like a "door". The bottom surface of the horizontal plate is fixedly connected to the other end of the spring 17. Under the elastic force of the spring 17, the fixing rod 13 is pushed into the connecting hole of the connecting block 7, which enhances the tightness of the fit between the fixing rod 13 and the connecting hole, and ensures the stability of the frame connection. It is the key structure to achieve automatic locking. Filter plate 15: Filter plate 15 is a sewage filtration component. It is slidably engaged in the sliding groove on the side wall of frame 2 5. The filter holes correspond to the water outlet holes of frame 2 5. It can intercept impurities in the flushing sewage, prevent the water outlet holes from being blocked, and can be pulled out and disassembled for individual cleaning or replacement. This avoids poor drainage caused by the accumulation of impurities. It is an important component to ensure the normal drainage of the cleaning system. Deflector plate 16: Deflector plate 16 is a sewage guiding component. It is fixed to the bottom of the frame 25 and faces the corrugated plate 10. It is inclined and can guide the sewage after cleaning the corrugated plate to the outlet hole, speed up the sewage discharge, prevent sewage from accumulating in the frame, reduce impurities, and improve the drying efficiency after cleaning. It is a key structure for optimizing the drainage path. Spring 17: Spring 17 is an elastic component of connecting component two. It is fixed to the bottom surface of the connecting groove of frame two 5, and the other end is connected to the bottom surface of the horizontal plate of sliding plate 14. Through its own elastic force, it pushes sliding plate 14 and fixing rod 13, so that fixing rod 13 is tightly inserted into the connecting hole of connecting block 7, which enhances the firmness of frame connection. When disassembling, compressing spring 17 can release fixing rod 13. It is the core power component for realizing quick locking and unlocking.

[0031] Working principle: In air filtration mode, the airflow passes through the frame composed of frame 3 and frame 5, and flows through the corrugated plates 10 and 11 arranged alternately on the connecting support plate 8. Since the corrugations of the two plates are opposite in direction, the airflow forms a disturbance in the gap. Combined with the guide lines 12 on the corrugated surface, the contact area with the air is greatly increased, improving the dust holding capacity and filtration efficiency. The rubber pads 9 at the four corners of the connecting support plate 8 reduce the hard wear caused by vibration. The corner brackets 1 and rubber pads 2 reinforce the corners of the frame, ensuring structural stability during filtration and preventing air leakage due to airflow impact.

[0032] When cleaning is required, quick assembly and disassembly can be achieved by connecting component one and connecting component two: pull the fixing rod 13 outward to disengage the fixing rod 13 from the connecting hole of the connecting block 7. At this time, frame one 3 and frame two 5 are separated, and the connecting support plate 8 and corrugated plate assembly can be taken out. If in-situ cleaning is to be performed, there is no need to disassemble the frame. The water source can be directly connected to the water inlet hole 4 of frame one 3. The water flow is distributed to multiple spray nozzles 6 through the internal water pipe. Each spray nozzle 6 is precisely aligned with the corresponding corrugated plate one 10 or corrugated plate two 11 to form directional rinsing.

[0033] During the rinsing process, the water flows along the guide lines 12 on the surface of the corrugated plate, forming turbulence in the interlaced corrugations, which enhances the removal effect on the attached dust. The wastewater generated by rinsing is guided by the guide plate 16 at the bottom of the frame 2 5 and flows to the outlet hole. When it flows through the filter plate 15, impurities are intercepted on the filter holes to avoid clogging the outlet hole, and the wastewater is discharged smoothly. After cleaning, if the filter plate 15 has a lot of dust, it can be directly pulled out from the sliding groove for separate cleaning or replacement to ensure the continuous smooth flow of the drainage system.

[0034] During reassembly, the connecting block 7 of frame 1 3 is inserted into the connecting slot of frame 2 5. As the connecting block 7 moves down, the spring 17 compresses and pushes the sliding plate 14 down. At the same time, the side wall of the connecting block 7 pushes the fixing rod 13 to move outward temporarily. When the connecting hole is aligned with the fixing rod 13, the fixing rod 13 is automatically engaged in the connecting hole, achieving a stable connection of the frames. The whole process can be completed without tools.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
