[0023] The anti-burning heat-resistant conveying belt in the embodiments of the present application comprises, from top to bottom, a high-temperature-resistant covering layer 1, an anti-burning layer 2, a heat-insulating layer 3, a metal mesh skeleton layer 4, and a bottom buffer layer 5;

[0024] The high-temperature-resistant covering layer 1 is made of ternary ethylene-propylene rubber and silicon carbide particles, has a thickness of 0.5-1.5 mm, and is provided with uniformly distributed semispherical protruding structures 11 on the surface;

[0025] The anti-burning layer 2 is made of a composite lamination of ceramic fiber cloth and fire-retardant silica gel, and is internally embedded with longitudinally equidistantly arranged metal support ribs 21;

[0026] The heat-insulating layer 3 has a double-layer structure, comprising an aerogel filling layer 1 and a ceramic fiber felt layer 32;

[0027] The metal mesh skeleton layer 4 adopts a wave-shaped stainless steel wire woven mesh, and has a mesh density of 10-15 meshes;

[0028] The bottom buffer layer 5 is made of polyurethane foaming material, and provides stability.

[0029] To further optimize the above technical solution, the semispherical protruding structures 11 are uniformly and spacedly arranged on the high-temperature-resistant covering layer 1, the spacing between adjacent protrusions is 10-15 mm, and the surface of the protrusions is coated with a nano-aluminum oxide coating.

[0030] To further optimize the above technical solution, the metal support rib 21 is made of titanium alloy material, and the rib spacing is 50-80mm.

[0031] To further optimize the above technical solution, the aerogel filling layer 31 and the ceramic fiber felt layer 32 are alternately bonded by a high-temperature-resistant adhesive.

[0032] To further optimize the above technical solution, the metal mesh skeleton layer 4 is provided with a cladding type anti-edge falling structure 41 on both sides of the edge, and the structure is made of fluororubber material.

[0033] Working principle: the anti-burning heat-resistant conveying belt mainly improves the anti-burning, high-temperature resistance and heat insulation performance through the structure design of layer-by-layer composite. In the use process, when the material passes through the surface of the conveying belt, the high temperature is first resisted by the high-temperature-resistant covering layer 1, and the friction is increased by the semispherical protruding structure to prevent the material from sliding. The anti-burning layer 2 further prevents the penetration of high temperature, and the ceramic fiber cloth and the flame-retardant silicone composite material can effectively insulate high temperature, and the metal support rib provides additional heat dissipation function. The heat insulation layer 3 greatly reduces the heat conduction through the combination of aerogel and ceramic fiber felt, so that the internal temperature of the conveying belt is kept within a safe range. The metal mesh skeleton layer 4 enhances the strength of the conveying belt, prevents deformation under high-temperature working conditions, and provides good air permeability and stability. The bottom buffer layer 5 adopts polyurethane foaming material, which enhances the impact resistance and stability of the conveying belt.

[0034] The anti-burning heat-resistant conveying belt provided by the utility model, the high-temperature-resistant covering layer and the anti-burning layer effectively resist the influence of high-temperature environment, and ensure that the conveying belt works stably under high-temperature conditions. The heat insulation layer adopts aerogel and ceramic fiber felt, which significantly reduces heat conduction and ensures that the internal temperature of the conveying belt is appropriate. The metal mesh skeleton layer provides strong support force, which ensures that the conveying belt is not easy to deform or damage under long-time high temperature. The drainage groove design of the bottom buffer layer effectively removes moisture, avoiding damage to the conveying belt caused by accumulated water. Due to the adoption of the multilayer composite structure and high-temperature-resistant materials, the conveying belt provided by the utility model has a longer service life and lower maintenance cost. The conveying belt can be widely applied to high-temperature organic fertilizer conveying in agricultural irrigation systems, greenhouse heating pipeline heat transmission and biomass combustion residue recycling scenes, and has significant economic benefits and safety improvement.
