最近机械工业部第六设计研究院与天津市机床钣焊件厂共同研制成一种用压缩空气诱导,塑料滤管过滤的移动式除尘机组(见图1),已于一九八二年底通过了技术鉴定,开始投入批量生产。该机可用于铸工车间合箱清灰、皮带机撒落砂清理、除锈打磨做业,机床铁末清除等各种分散杨尘点和电焊排烟,还可以用来吸除污水,用途相当广泛。采用塑料滤管作为滤料具有净化效率高,使用寿命长、不怕潮湿、耐酸、耐碱、清灰方便等特点,克服了绦纶208绒布等织物滤料的固有弱点。
Recently, the Sixth Design and Research Institute of the Ministry of Machinery Industry and the Tianjin Machine Tool Titanium Weldment Plant jointly developed a mobile dust collection unit that was induced by compressed air and filtered by a plastic filter tube (see Figure 1). It was adopted at the end of 1982. Technical appraisal, began to put into mass production. The machine can be used for the box cleaning of the casting workshop, sand belt cleaning, rust removal and polishing, various iron dust removal points and welding exhaust fumes from machine tools, and can also be used to remove sewage. widely. The use of plastic filter tubes as filter media has the characteristics of high purification efficiency, long service life, no fear of moisture, acid, alkali, and convenient ash removal, and overcomes the inherent weaknesses of fabrics such as polyester 208 velvet fabrics.
