[0030] The structure of the present application will be described in detail below in conjunction with the drawings.

[0031] Reference Figures 1-5 An anti-erosion composite metal screen, comprising a fixed outer frame 1, telescopic rods 2 are fixedly installed on the left and right sides of the fixed outer frame 1, a connecting frame 3 is arranged at the middle of the plurality of telescopic rods 2, fixed bolts 4 are fixedly installed on the top of the connecting frame 3, knobs 5 are fixedly installed on the outer side of one end of the fixed bolts 4, a composite metal screen body 6 is arranged between one side of the fixed outer frame 1, the composite metal screen body 6 comprises a protective outer layer 7, an anti-erosion middle layer 8 is fixedly installed on one side of the protective outer layer 7, and an anti-corrosion inner layer 9 is fixedly installed on one side of the anti-erosion middle layer 8.

[0032] In the embodiment, the protective outer layer 7 comprises a protective surface layer 10, a buffer intermediate layer 11 and a heat-conducting reinforced bottom layer 12. The buffer intermediate layer 11 is fixedly installed on one side of the protective surface layer 10, and the heat-conducting reinforced bottom layer 12 is fixedly installed on one side of the buffer intermediate layer 11. The material of the protective surface layer 10 is nickel-based alloy. The nickel-based alloy has excellent corrosion resistance and can resist chemical corrosion of acidic, alkaline solution and chlorine ion-containing corrosive medium environment. In use, it can prevent corrosive media from eroding the screen body and prolong its service life. Its high hardness and good wear resistance can resist physical abrasion such as friction of particulate materials during screening. The material of the buffer intermediate layer 11 is rubber. Rubber has good elasticity and can play a buffering role when the screen is impacted by external forces such as material impact and installation collision, thereby protecting the inner layer structure. The material of the heat-conducting reinforced bottom layer 12 is copper-aluminum alloy. The copper-aluminum alloy has good heat-conducting performance and can quickly conduct heat when the screen is locally heated by friction, thereby avoiding excessive local temperature that affects performance or accelerates corrosion. In addition, it can provide stable support for the outer layer and enhance the overall integrity.

[0033] In the embodiment, the anti-erosion intermediate layer 8 comprises a screen body layer 13, a reinforcing rib layer 14 and an anti-clogging coating 15. The reinforcing rib layer 14 is fixedly installed on one side of the screen body layer 13, and the anti-clogging coating 15 is fixedly installed on one side of the reinforcing rib layer 14. The material of the screen body layer 13 is stainless steel. Stainless steel has good corrosion resistance and good resistance to chlorine ion-containing media, and can resist corrosion to ensure the basic function of the screen. Its strength and hardness can withstand the pressure and friction force of material screening, and the size and shape precision of the mesh are suitable to ensure the accuracy and efficiency of screening. The material of the reinforcing rib layer 14 is titanium alloy. Titanium alloy has high strength, low density and good corrosion resistance, and can enhance the overall strength and rigidity of the screen when arranged in the intermediate layer, thereby preventing the screen from deforming under stress during long-term use and ensuring the screening accuracy and stability without increasing the burden of the screen. The material of the anti-clogging coating 15 is polytetrafluoroethylene coating. The polytetrafluoroethylene coating has a very low surface friction coefficient, which can prevent material from accumulating and clogging on the surface of the screen and in the mesh, thereby improving the screening efficiency and reducing the frequency of manual cleaning. In addition, it has certain chemical corrosion resistance and can enhance the anti-erosion ability of the screen.

[0034] In the embodiment, the anticorrosion inner layer 9 comprises an anticorrosion bottom layer 16, an insulating isolation layer 17 and a bonding reinforcement layer 18. The insulating isolation layer 17 is fixedly installed on one side of the anticorrosion bottom layer 16, and the bonding reinforcement layer 18 is fixedly installed on one side of the insulating isolation layer 17. The material of the anticorrosion bottom layer 16 is a zinc-nickel alloy coating. The zinc-nickel alloy coating provides anticorrosion protection for the screen through the principle of sacrificial anode protection. When the outer protective layer is partially damaged, the zinc-nickel alloy coating preferentially corrodes, releases electrons to inhibit the oxidation reaction of the main metal of the screen, prolongs the overall service life, and has good anticorrosion effect on hidden or difficult-to-maintain areas. The material of the insulating isolation layer 17 is a ceramic coating. The ceramic coating has excellent insulating properties and can effectively isolate static electricity when the screen is used to screen dry powdery materials that have the risk of generating static electricity, preventing the accumulation of static electricity from damaging the screen and surrounding equipment. In addition, the ceramic coating has certain corrosion resistance and high temperature resistance, improving the overall performance. The material of the bonding reinforcement layer 18 is epoxy resin glue. The epoxy resin glue has strong bonding force and can tightly bond the layers of the inner layer and the inner layer and the middle layer, fill small gaps, prevent corrosive media from penetrating into the interior of the screen, ensure the structural stability of the screen, and avoid delamination.
