[0041] Please also read Figures 1 to 6 Now, the plate filter provided by the utility model is described. The plate filter comprises a first frame 1, a positioning mesh plate 2, a second frame 3, a positioning strip 4 and filter cotton 5; the positioning mesh plate 2 is a serrated mesh plate, and the edge of the positioning mesh plate 2 is connected to the inner side of the first frame 1; the second frame 3 is hinged to the first frame 1; the positioning strip 4 is connected to the inner side of the second frame 3, and the long axis is perpendicular to the extension direction of the positioning mesh plate 2, and the positioning strip 4 corresponds to the tooth valley 201 of the positioning mesh plate 2; the filter cotton 5 is attached to the first side surface of the positioning mesh plate 2, and the positioning strip 4 cooperates with the positioning mesh plate 2 to clamp the filter cotton 5 in the tooth valley 201 area of ​​the positioning mesh plate 2.

[0042] In this embodiment, the first frame 1 and the second frame 3 are exemplarily shown as rectangular frame structures. It should be understood that the first frame 1 and the second frame 3 can also be designed as other polygonal frame structures, which can be selectively designed according to actual usage requirements and are not limited here.

[0043] In this embodiment, the long axis of the positioning bar 4 is exemplarily shown as being parallel to the hinge axis of the first frame 1 and the second frame 3, and the positioning mesh plate 2 extends in a direction perpendicular to the hinge axis; however, it should be understood that the extension direction of the positioning mesh plate 2 and the positioning bar 4 is not limited to the methods listed in the accompanying drawings, and other methods can also be used. For example, the long axis of the positioning bar 4 is perpendicular to the hinge axis, and the positioning mesh plate 2 extends in a direction parallel to the hinge axis, which can meet the assembly and use requirements of the filter cotton 5. The remaining implementation methods are not listed here one by one.

[0044] In this embodiment, the positioning mesh plate 2 is preferably arranged on the downstream side of the filter cotton 5 to ensure that the filter cotton 5 is fully fitted to the positioning mesh plate 2 when the airflow passes through, so as to achieve effective positioning through the positioning mesh plate 2.

[0045] In this embodiment, in order to achieve adaptation with the tooth valley 201 on the positioning mesh plate 2 and adapt to the connection with the second frame 3 , both ends of the positioning strip 4 are bent, and the bent ends are connected to the second frame 3 .

[0046] Compared with the prior art, the plate filter provided in this embodiment adopts a hinged manner and can be opened and closed. When the first frame 1 and the second frame 3 are buckled, the positioning mesh plate 2 can cooperate with the positioning bar 4 to achieve the clamping and fixing of the filter cotton 5. The middle of the first frame 1 and the second frame 3 is left empty as a filtering channel for the circulating gas. The plate filter is installed in the filter system as a whole to achieve filtering. During maintenance, the plate filter is removed from the system as a whole, the first frame 1 and the second frame 3 are opened, the positioning mesh plate 2 and the positioning bar 4 are separated from each other, the clamping of the filter cotton 5 is released, and the first frame 1 and the second frame 3 are buckled again after replacing the new filter cotton 5. The plate filter is reinstalled in the filter system as a whole. This embodiment can realize the operation of replacing only the filter cotton 5, the external frame structure can be reused, avoiding the overall replacement, and the replacement and maintenance cost of the filter is greatly reduced; in addition, the clamping and positioning method combining the positioning bar 4 and the positioning mesh plate 2 is adopted, and the positioning mesh plate 2 provides a larger support and positioning area for the filter cotton 5, effectively improving the reliability of the clamping and positioning. At the same time, the mesh plate design does not affect the gas circulation, ensuring stable and reliable filtering performance.

[0047] In some embodiments, the plate filter further comprises a support bar 6 connected to the first frame 1, such as Figures 1 to 5As shown, the long axis of the support bar 6 is perpendicular to the extension direction of the positioning mesh plate 2 and is located on the second side of the positioning mesh plate 2. The second side is arranged opposite to the first side, and the support bar 6 is supported at the tooth peak 202 of the positioning mesh plate 2. After assembly, the support bar 6 supports the tooth peak 202 on the second side, and the positioning bar 4 supports the tooth valley 201 on the first side. In conjunction with the connection between the edge of the positioning mesh plate 2 and the first frame 1, during use, the positioning mesh plate 2 can effectively maintain a serrated shape, thereby allowing the filter cotton 5 to maintain a serrated shape without deformation, and the filtering performance is stable and reliable. In addition, by cooperating with the positioning bar 4 and the support bar 6 to maintain the serrated shape of the positioning mesh plate 2, the strength requirements of the material of the positioning mesh plate 2 itself are relatively low, and thus a relatively dense mesh can be set on the positioning mesh plate 2, and the intervals between the meshes can also be designed to be smaller, thereby minimizing the wind resistance caused by the positioning mesh plate 2 and ensuring filtering performance.

[0048] In this embodiment, in order to achieve the adaptation with the tooth peaks 202 on the positioning mesh plate 2 and adapt to the connection with the first frame 1, the two ends of the support bar 6 are bent, and the bent ends are connected to the first frame 1. In addition, the positioning mesh plate 2 can be formed by weaving metal wires, the mesh number is not less than 3 meshes (for example, 4 meshes), and the diameter of the metal wire is not less than 0.8 mm.

[0049] In some embodiments, the serrated side edge of the positioning mesh plate 2 is provided with a reinforcing connecting plate 7, such as Figure 1 As shown, the reinforcing connecting plate 7 is a serrated plate member arranged in accordance with the serrated side edge of the positioning mesh plate 2, and the reinforcing connecting plate 7 is connected to the first frame 1. The arrangement of the reinforcing connecting plate 7 has the following beneficial effects: first, it can cover the edge of the positioning mesh plate 2 to prevent the burrs on the edge of the positioning mesh plate 2 from scratching the operator; second, the shape of the edge of the positioning mesh plate 2 is fixed, further improving the structural stability of the positioning mesh plate 2 during use; third, the reinforcing connecting plate 7 also makes it easier for the edge of the positioning mesh plate 2 to be connected to the first frame 1 (for example, by welding), reducing the difficulty of assembly.

[0050] See also Figure 2In some embodiments, the plate filter further comprises a locking assembly, which comprises a guide frame 8, a latch 9, an elastic member 10 and an insert ring 11; the guide frame 8 is arranged on the inner side of the second frame 3, and the latch 9 is slidably connected to the guide frame 8; the elastic member 10 is arranged between the guide frame 8 and the latch 9, and is configured with a pre-tightening force that causes the insertion end of the latch 9 to extend out of the guide frame 8; the insert ring 11 is arranged on the inner side of the first frame 1, and the insertion end of the latch 9 is plugged into and matched with the insert ring 11. In the process of the first frame 1 and the second frame 3 being engaged, the latch 9 is moved so that its insertion end is staggered with the insert ring 11, so that the first frame 1 and the second frame 3 can be effectively engaged and docked. After docking, the latch 9 is released, and the insertion end of the latch 9 is automatically stuck in the insert ring 11, so as to realize the locking of the first frame 1 and the second frame 3, and under the action of the elastic member 10, the insertion end can be stably plugged into the insert ring 11, maintaining an effectively locked state, and having good stability in use. In addition, the locking components are all located on the inner side of the frame structure, and the outer side surfaces of the first frame 1 and the second frame 3 have good flatness, which facilitates the loading and unloading operations of the plate filter in the system.

[0051] In some specific embodiments of the guide frame 8, the guide frame 8 includes a guide connecting plate 810 and a plurality of guide rings 820, the guide connecting plate 810 is fitted and connected to the inner side surface of the second frame 3, and a plurality of guide rings 820 are arranged on the guide connecting plate 810 at intervals along the circumference of the second frame 3, and the plurality of guide rings 820 cooperate to form a guide channel; the latch 9 is inserted into the plurality of guide rings 820, and the insertion end can extend out of the guide ring 820 located at the end; the elastic member 10 is sleeved on the outer periphery of the latch 9 and is located between two adjacent guide rings 820, one end of the elastic member 10 abuts against the guide ring 820, and the other end is connected to the latch 9. When the first frame 1 is buckled with the second frame 3, the plug ring 11 can directly correspond to the guide ring 820 located at the end, and the insertion end of the latch 9 can be inserted into the plug ring 11. Among them, the implementation of the elastic member 10 includes but is not limited to a spring, a rubber sleeve, etc. In this embodiment, the guide frame 8 has a compact overall structure, can effectively guide the latch 9 and effectively connect with the second frame 3, and at the same time, fully utilizes the internal space to set the elastic member 10, which is conducive to making the locking assembly as a whole have a higher structural compactness.

[0052] In a specific implementation, a guide ring 820 is provided on the outer peripheral surface of the insert ring 11, and the mounting plate 12 is closely connected to the first frame 1, wherein the insert ring 11 and the mounting plate 12 can be integrally bent and formed by the same plate.

[0053] In a specific implementation, an operation avoidance notch 302 corresponding to the latch pin 9 and the insert ring 11 is formed on the second frame 3 to facilitate the movement of the latch pin 9 .

[0054] More specifically, in order to avoid affecting the gas circulation, the guide frame 8 and the insert ring 11 are arranged close to the corners of the second frame 3, and the insert ring 11 is also arranged close to the corners of the first frame 1 to avoid blocking the effective filtering surface of the filter cotton 5.

[0055] See also Figure 1 and Figure 2 In some embodiments, a guide frame 8 is provided on the second opening and closing side of the second frame 3 opposite to the hinged side thereof, and a second opening and closing reinforcing flange 310 bent inwardly is provided on one side edge of the second opening and closing side facing the first frame 1; an insert ring 11 is provided on the first opening and closing side opposite to the hinged side thereof, and a first opening and closing reinforcing flange 110 bent inwardly is provided on one side edge of the first opening and closing side facing the second frame 3, the insert ring 11 extends out of the first opening and closing reinforcing flange 110, and a locking avoidance notch 301 corresponding to the insert ring 11 is provided on the second opening and closing reinforcing flange 310. The locking assembly is selectively provided on the second opening and closing side and the first opening and closing side, which is convenient for operation and provides a more reliable locking effect, but the second opening and closing side and the first opening and closing side need to bear a larger locking force. By providing the second opening and closing reinforcing flange 310 and the first opening and closing reinforcing flange 110, the structural strength of the second opening and closing side and the first opening and closing side can be ensured, and the second opening and closing side and the first opening and closing side can be prevented from being deformed after repeated use, thereby extending the service life of the frame structure and further reducing the use cost.

[0057] More specifically, the second opening and closing reinforced flange 310 has a second opening and closing protrusion 311, and the first opening and closing reinforced flange 110 has a first opening and closing protrusion 111. The second opening and closing protrusion 311 and the first opening and closing protrusion 111 correspond to each other, and both correspond to the locking component setting, which not only does not affect the use of the locking component, but also enables the second opening and closing reinforced flange 310 and the first opening and closing reinforced flange 110 in the area to have sufficient structural strength, and finally realizes the rational setting of the width of the first opening and closing reinforced flange 110 and the second opening and closing reinforced flange 310, reduces the material consumption while ensuring the structural strength, and is conducive to achieving lightweight design.

The hinge area of ​​the first hinge plate 1310 and the second hinge plate 1320 is exposed outside the first frame 1 and the second frame 3 through the first exposure opening and the second exposure opening. The hinge 13 can realize a rotation opening and closing of not less than 150° between the first frame 1 and the second frame 3, making the operation of replacing the filter cotton 5 more convenient.

[0067] participate Figure 1 , Figure 3 and Figure 6 In some embodiments, the filtration system includes a plurality of plate filters connected in sequence, and the plate filters also include a first bracket 15 and a second bracket 16, which are respectively located on opposite sides of the outer periphery of the first frame 1, the first bracket 15 is connected to the first frame 1, and the second bracket 16 is connected to the second frame 3, and the first bracket 15 can be connected to the second bracket 16 on the adjacent plate filter. In some usage scenarios, the filtration area of ​​a single plate filter is difficult to meet the usage requirements, and multiple plate filters are often required to be arranged side by side, and the plate filters are slidably matched with the system frame, so that the plate filters can be disassembled and assembled by pulling and pulling; based on this premise, when the plate filters are installed one by one in the system frame, the first bracket 15 and the second bracket 16 can be matched to connect the adjacent plate filters in a hanging manner, and when replacing, multiple plate filters arranged side by side can be pulled out at the same time to improve the efficiency of the replacement operation.

[0068] For more details, see Figure 1 , Figure 3 and Figure 6 The first bracket 15 is a long strip frame extending along the circumferential contour of the first frame 1, and the second bracket 16 is a long strip frame extending along the circumferential contour of the second frame 3, so that the first bracket 15 and the corresponding second bracket 16 have a larger hanging contact area, which improves the stability of the hanging. At the same time, the first bracket 15 and the second bracket 16 can cooperate to effectively block the gap between two adjacent plate filters, minimize the air leakage between two adjacent plate filters, and ensure the effectiveness of filtration.

[0069] More specifically, the first bracket 15 and the second bracket 16 are both bent plates, and the cross-sections of both are "Z"-shaped, so that the first bracket 15 forms a first hook portion spaced apart from the outer peripheral surface of the first frame 1, and the second bracket 16 forms a second hook portion spaced apart from the outer peripheral surface of the second frame 3. The extension directions of the first hook portion and the second hook portion are opposite, so that the two plate filters are roughly flush after being hung.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
