Machine-made sand modification device based on ultraviolet irradiation
The invention discloses a machine-made sand modification device based on ultraviolet irradiation, the machine-made sand modification device comprises a material conveying belt, an ultraviolet generating device and a machine-made sand tiling device, the ultraviolet generating device is fixedly arranged on the material conveying belt, so that machine-made sand on the material conveying belt is located in the irradiation range of the ultraviolet generating device; the ultraviolet generating device at least can emit ultraviolet rays with three different wave bands, namely UVA, UVB and UVC; the machine-made sand tiling device is fixedly arranged at the feeding end of the conveying belt. The machine-made sand tiling device can tiling machine-made sand on the material conveying belt in a single layer mode, ultraviolet rays in the wave bands of UVA, UVB and UVC emitted by the ultraviolet ray generating device can weaken the association effect of hydrogen bonds on the surface of the machine-made sand, a network structure formed after polyacrylamide and other flocculants are hydrolyzed is cracked, and attached microorganisms are killed, and the rheological property of the cement concrete containing the machine-made sand can be improved.
本发明公开了一种基于紫外线照射的机制砂改性装置，其包括输料皮带、紫外线发生装置和机制砂平铺装置，其中，紫外线发生装置固定设置在输料皮带的上方，使得输料皮带上的机制砂处于紫外线发生装置的照射范围内，紫外线发生装置至少能够发出UVA、UVB和UVC三种不同波段的紫外线；机制砂平铺装置固定设置在输料皮带的进料端。机制砂平铺装置能够将机制砂单层平铺在输料皮带上，紫外线发生装置发出的UVA、UVB和UVC波段的紫外线能够削弱机制砂表面氢键的缔合作用，裂解聚丙烯酰胺等絮凝剂水解后形成的网络结构，并对附着的微生物具有灭杀作用，能够改善含机制砂水泥混凝土的流变性能。
