Sand reclamation system with thermal pipe reclaimer apparatus

摘要

A system (10) particularly suited for treating solid, granular and aggregate material by means of thermal reclamation. The subject (10) includes, arranged in cooperatively associated series relation, storage hopper means (12), heat exchanger means (14), thermal pipe reclaimer means (16) and cyclone scrubber means (18). The function of the storage hopper means (12) is to store therewithin a suitable supply of grain size material, which is to be treated. At a preestablished rate the material is fed from the storage hopper means (12) to the heat exchanger means (14). While traveling through the heat exchanger means (14) the material is preheated to a first temperature. From the heat exchanger means (14) after undergoing metal separation and crushing of lumps, the material is supplied to the thermal pipe reclaimer means (16) wherein the material is heated to a specified temperature for a predetermined period of time in order to effect the burning away of organic matter which the material embodies. After leaving the thermal pipe reclaimer means (16) the material travels to the cyclone/scrubber means (18) wherein the surface of the grain size material is cleansed and post reclamation of the material occurs. The material, which is now at a second temperature, is then again conveyed to the heat exchanger means (14) whereupon during the course of traveling therethrough the material is cooled to a suitable temperature.
