[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment 1

[0021] Please refer to Figures 1 to 5, the present utility model is a new type of distribution plate. Through the assembly between the support frame 1 and the sintered wire mesh 2, it can not only evenly distribute the airflow to maintain the fluidized state, but also has a filtering function, with high strength, low resistance, good backwashing reuse effect, economic and practical, and has great applicability.

[0022] Specifically, for the sintered wire mesh 2, there is a support frame 1 outside the sintered wire mesh 2. A wire mesh frame 201 welded to the surface side of the sintered wire mesh 2 is connected to the inner side wall of the support frame 1. An internal gasket 101 is arranged between the lower end surface of the sintered wire mesh 2 and the inner side of the support frame 1. An external gasket 105 is fixed to the bottom surface outside the support frame 1. A notch 104 is opened on the bottom surface inside the support frame 1, and the internal gasket 101 is fixed at the internal position of the notch 104.

[0023] The operation process of this embodiment is as follows: Through the setting and use of the above structure, the sintered wire mesh 2 used therein is formed by high-temperature vacuum sintering of multiple layers of metal woven wire meshes, and it is an asymmetric porous material with a rigid structure formed by high-temperature vacuum sintering. The mesh holes of each layer of such multiple-layer sintered wire mesh 2 intersect with each other to form a uniform and stable filtering structure. The support frame 1 is cut from a steel plate, and the sealing gasket is made of metal and can select high-temperature resistant and corrosion-resistant materials according to the fluid characteristics. The sintered wire mesh 2 and the support frame 1 can be separated, and the wire mesh can be thoroughly cleaned separately. Through the position of the internal gasket 101 between the support frame 1 and the sintered wire mesh 2, the gap between the two is sealed. The main function of the support frame 1 is, on the one hand, to support the sintered wire mesh 2, increase the strength of the sintered wire mesh 2, and extend its service life, and on the other hand, to maintain the uniformity of the wire mesh pores and avoid the reduction of the filtering performance caused by the deformation of the wire mesh due to the weight of the filler. Embodiment 2

[0024] Please refer to Figure 2 、 Figure 3 and Figure 4 , on the basis of Embodiment 1, through the cooperation of the T-shaped block 202 and the T-shaped opening 102, it is ensured that the wire mesh frame 201 can be calibrated and installed in the first time.

[0025] Specifically, a plurality of T-shaped openings 102 are evenly arranged on the circumferential wall on the side wall inside the support frame 1 that is in contact with the surface wall of the wire mesh frame 201. A plurality of T-shaped blocks 202 are fixed on the surface wall of the wire mesh frame 201 and are respectively inserted into the internal positions of the T-shaped openings 102. A plurality of threaded holes 103 are evenly arranged along the circumferential wall and penetrate through the surface side outside the support frame 1. Bolts 3 are spirally arranged inside the threaded holes 103. Positioning openings 203 are opened at the positions corresponding to each threaded hole 103 on the surface wall of the wire mesh frame 201, and the smooth end parts of the bolts 3 passing through the threaded holes 103 are respectively inserted into the corresponding positioning openings 203.

[0026] The operation process of this embodiment is as follows: Through the setting and use of the above structure, when installing the sintered wire mesh 2, align the T-shaped block 202 with the position of the T-shaped opening 102, and insert the T-shaped block 202 into the T-shaped opening 102. Then, the wire mesh frame 201 will be directly installed inside the support frame 1, and the positioning openings 203 on the surface of the wire mesh frame 201 will correspond to the positions of the threaded holes 103 one by one. At this time, screw the bolt 3 into the threaded hole 103, and then the smooth part at the end of the bolt 3 will be inserted into the positioning opening 203 to position the wire mesh frame 201 and install and position the sintered wire mesh 2.
