[0019] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0020] See also Figure 1~Figure 3 , the utility model embodiment includes:

[0021] like Figure 1 The ventilation plate shown, which is easy to maintain, includes: a frame 1, a support plate 6, a pressure plate 5, a baffle 3 and a filter wire strip 2. The frame includes a first longitudinal beam 11, a second longitudinal beam 12 and a cross beam 13. The two cross beams 11 are distributed parallel to each other up and down. The first longitudinal beam 11 is arranged at the front end of the two cross beams 13, and the second longitudinal beam 12 is arranged at the rear end of the two cross beams 11 to form a square structure. The first longitudinal beam 11 and the second longitudinal beam 12 are respectively fixed to the cross beam 13 by welding, and the structure is stable.

[0022] The filter strips 2 are arranged in parallel and spaced apart in the frame 1, and ventilation is performed through the gaps between adjacent filter strips 2. A positioning blind groove 14 corresponding to the front end of the filter strips 2 is concavely arranged on one side of the front side of the first longitudinal beam 11 near the second longitudinal beam 12 to position the front end of the filter strips 2.

[0023] The support plate 6 is longitudinally arranged between the two cross beams 13 and is located on the back side of the filter wire strip 2 for support. In the present embodiment, a second slot 17 corresponding to the end of the support plate 6 is concavely arranged on the back side of the cross beam 1. The end of the support plate 6 is welded and fixed to the cross beam 1, so the structure is stable and the support for the back side of the filter wire strip 2 is good.

[0024] The pressing plate 5 is longitudinally arranged between the two cross beams 13 and located on the front of the filter wire strip 2 for pressing and fixing. In this embodiment, the front of the cross beam 1 is concavely provided with a first clamping groove 16 corresponding to the end of the pressing plate 5 to position the end of the pressing plate 5. The pressing plate 5 is provided with a second screw 7 connected to the cross beam 1, which has a firm structure and is convenient for disassembly and assembly. In order to prevent the pressing plate 5 from protruding from the front of the filter wire strip 2, an embedding groove corresponding to the pressing plate 5 can also be processed on the front of the filter wire strip 2 to hide the pressing plate 5.

[0025] like Figure 1 As shown, the support plate 6 and the pressure plate 5 are spaced apart along the length direction of the cross beam 13 to support and press the filter wire strip 2, thereby improving the impact resistance of the filter wire strip 2. Figure 2As shown, the front side of the support plate 6 is concavely provided with a first positioning groove 8 corresponding one-to-one to the filter wire strips 2, and the front side of the second longitudinal beam 12 is concavely provided with a second positioning groove 15 corresponding one-to-one to the rear end of the filter wire strips 2. The first positioning groove 8 and the second positioning groove 15 are used to strengthen the positioning of the filter wire strips 2 to ensure the stability of the gap and the ventilation volume of adjacent filter wire strips 2.

[0026] like Figure 2 As shown, the cross-sections of the positioning blind groove 14, the first positioning through groove 8 and the second positioning through groove 15 are respectively V-shaped or isosceles trapezoidal, and the cross-section of the filter wire strip 2 is an isosceles trapezoidal, which fits tightly and has high positioning stability, thus avoiding twisting of the filter wire strip 2.

[0027] In order to prevent the filter wire strip 2 from moving outward in the axial direction, the baffle plate 3 is arranged outside the second longitudinal beam 12 to block the second positioning slot 15. In this embodiment, the baffle plate 3 is provided with a first screw 4 connected to the cross beam 1, which is convenient for disassembly and assembly. Figure 3 As shown, after the baffle 3 is removed, the filter wire strip 2 can be pulled out and inserted, thereby improving the convenience of maintenance.

[0028] In summary, the utility model points out a ventilation plate which is easy to maintain, can position, support and press the filter strips, improve the stability of the filter strips, ventilate the gaps between adjacent filter strips, ensure the ventilation volume, and the filter strips can be replaced individually after being damaged, so the maintenance operation is simple and the cost is low.

[0029] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
