Protection box for filter components

Abstract

The invention discloses a protection box for filter components. The protection box comprises a box bottom, a first protection box cover and a second protection box cover. The box bottom comprises a box bottom body. A plurality of air diversion trenches are formed in the box bottom body. A plurality of box bottom supporting skeletons are fixedly connected to the box bottom. The first protection box cover comprises a first protection box cover body. First protection box cover skeletons are connected to the middle of the first protection box cover body. Ventholes are formed between the first protection box cover skeletons. A first protection box cover supporting groove is formed in the middle of the connection between the first protection box cover skeletons. The protection box is advanced and reasonable in structural design, and has been verified through multiple tests by company laboratories, and the exhalation resistance and the inhalation resistance are up to the international standards demanded by the national inspection center. The water and mud splashing preventing effect is good. The integral structure is simple, the cost is low, the practicability is high, and popularization and application are easy.

Description

technical field [0001] The invention relates to the technical field of resource and environment applications, in particular to a filter element protection box. Background technique [0002] At present, when Chinese enterprises producing respiratory protection products produce respiratory protection filter elements for coal mine workers, they focus on how to improve the raw materials, formula and manufacturing process of filter elements, so as to improve the respiratory protection time, while ignoring Influence of working environment in coal mine on respiratory protection time. Most of the existing domestic respiratory mask filter elements are single filter elements without any protective device outside the filter element, and the filter element itself does not have waterproof function. However, there are procedures for water spraying and dust reduction when working underground in coal mines, and coal mine mud splashes onto the filter elements from time to time during the un...

Most of the existing domestic respiratory mask filter elements are only a single filter element, and there is no protective device outside the filter element, and the filter element itself does not have waterproof function

However, there are procedures for water spraying and dust reduction when working underground in coal mines, and coal mine mud splashes onto the filter elements from time to time during the underground mining process. The wet working environment and the splashing of coal mine mud will reduce the protection efficiency of the filter elements. The main reason
