Cold-proof and wear-resistant cable of grate cooler

Abstract

The invention relates to the field of clinker cooling, in particular to a cable of a cooling cement clinker grate cooler and a cold-proof and wear-resistant cable of a grate cooler. The cold-proof and wear-resistant cable of the grate cooler comprises two copper alloy wire cores, an insulation layer, an outermost wear-resistant layer, a cold-proof shielding layer, a fireproof layer, a winding layer, a filling layer and a central isolation layer, wherein the outermost wear-resistant layer comprises polyvinylchloride resin, 2,4-dihydroxy benzophenone, carbon black, a stabilizer, an anti-oxygen agent and a plasticizer, and the cold-proof shielding layer comprises a PET resin layer and ITO nanoparticles dispersed in the PET resin layer. By the cold-proof and wear-resistant cable, the weather resistance, the aging resistance and the wear resistance can be improved, the cold-proof and wear-resistant cable has a heat absorption and cold resistant effect, the effect of shielding electron radiation is simultaneously developed, the cable manufacturing cost can be further reduced, the cable production and preparation time is greatly reduced, favorable adhesivity among layers is ensured, and the dead weight of the cable also can be reduced.

Description

Technical field: [0001] The invention relates to the field of clinker cooling, in particular to a cable in a grate cooler for cooling cement clinker, in particular to a grate cooler cold-proof and wear-resistant cable. Background technique: [0002] As we all know, the grate cooler is an important equipment in the cement clinker burning system. Its main function is to cool and transport the cement clinker, and at the same time provide hot air for the rotary kiln and calciner. In the cement production process, the grate cooler is used as a quenching cooler. When the cement clinker enters the grate cooler, a material layer of a certain thickness is laid on the grate plate, and the cold air blown in is perpendicular to each other. The direction passes through the moving material layer on the grate bed to quench the clinker, and the clinker can be quenched from 1300-1400°C to below 100°C within a few minutes. In this way, the internal production environment of the grate cooler ...
