本文介绍了按重力加砂横吹原理设计、在我国首次研制成功的3吨/时横吹式旧砂气流再生机。它为中小厂旧砂再生提供了一条新途径。该机具有结构简单、运行可靠、设备紧凑、维修方便、耗能低、对水分要求不严等特点。文章对这一设备的工作原理、结构、主要参数及计算、配套设备、使用效果作了系统的介绍。
In this paper, we introduce the 3-ton / hour horizontal blown old sand airflow regenerator successfully developed in our country for the first time according to the principle of gravity plus sand horizontal blowing. It provides a new way for the regeneration of old sand in small and medium-sized factories. The aircraft has a simple structure, reliable operation, compact equipment, easy maintenance, low energy consumption, lax requirements of water and other characteristics. This article systematically introduces the working principle, structure, main parameters and calculation of this equipment, ancillary equipment, the use of results.
