Description

Filter bag with step-by-step filtering function Technical Field The utility model relates to the technical field of filter bags, in particular to a filter bag with a step-by-step filtering function. Background In the production process of workshops, in order to ensure the cleanness of the air in the workshops, a filter is generally required to be used for extracting the air in the workshops and filtering treatment is carried out, a filter bag is an important component part of the filter, the filter bag has excellent chemical property stability and heat resistance, is a representative of the application in the filter material industry, is a product with better performance in all common filter materials, reaches higher level in the aspects of filtering efficiency, filtering precision and the like, and ensures that the air impacts the surface of the filter bag and intercepts particles in the air through the filter bag. However, when the existing filter bag filters air, due to the fact that particulate matters in the air are intercepted through the filter bag, after the filter bag is used for a long time, more dust is attached to the surface of the filter bag, the smoothness and the filtering effect of subsequent gas circulation are affected, and due to the fact that only a single filter bag is arranged in the filter bag, the filtering and dust removing effect is poor, and popularization and use are not facilitated. The application provides a filter bag with a step-by-step filtering function in order to solve the problem. Disclosure of utility model The utility model aims to provide a filter bag with a step-by-step filtering function, so as to solve the problems that the filter bag provided in the background art can be used for a long time, and the surface of the filter bag is attached with more dust, and only a single filter bag is arranged in the filter bag, so that the smoothness and the filtering effect of subsequent gas circulation are affected, the filtering and dust removing effects are poor, and the using effect is poor.
