我国现行的测尘方法,是以滤膜测尘法为主。目前常用的测尘仪器,有武安型C1型、武安72型、鞍劳D—4型等,都是以电机作为采样动力。此外,在井下也有利用引射器(喷射器)采样的。但煤矿中测尘的防爆问题,一直没有很好的解决。为了解决井下测尘的实际需要,我们参考了北票县卫生防疫站制成的“简易小型引射器”体积小、耗气量低、操作简便等优点和武安72型、鞍劳D—4型的结构,试制了一个井下小型粉尘采样器,现简介如下。
The current method of measuring dust in our country is mainly based on the method of dust film filtration. Currently used dust detection equipment, a Wu-type C1, Wu-72, saddle labor D-4 type, are based on the motor as a sampling power. In addition, there are also downhole injector (injector) sampling. However, explosion-proof dust in coal mines, has not been a good solution. In order to solve the actual needs of underground dust measurement, we refer to the Beipiao Health and Epidemic Prevention Station made of “simple small ejector” small size, low air consumption, easy operation and other advantages and Wuan 72, saddle labor D-4 Structure, trial production of a small underground dust sampler, are briefings are as follows.
