Bulkhead air-purifying respirator

Abstract

The invention discloses a bulkhead air-purifying respirator comprising a shell, a closed telescopic pipe, an elastic filter screen, a regulating assembly, a partition plate and bulkhead ring plates. According to the bulkhead air-purifying respirator, the bulkhead ring plates are additionally arranged, and are of a big-end-down conical ring body structure; the peripheral side of the elastic filterscreen is connected with the multiple bulkhead ring plates from top to bottom uniformly, and ventilation ring grooves are formed among the bulkhead ring plates; thus, air flow is filtered through bulkheads of the bulkhead ring plates before entering the elastic filter screen, so that large particle impurities flow downwards along the bulkhead ring plates of the conical ring body structure after impacting the bulkhead ring plates; the impact of the large particle impurities on the elastic filter screen is reduced greatly, and the filtration load of the elastic filter screen is reduced; and thefiltering effect is further improved.

Description

technical field [0001] The invention relates to a filter type respirator with partitions. Background technique [0002] The respirator is generally installed on the crushing chamber or pipeline of the pulverizer to discharge gas, filter dust, and reduce dust pollution in the external environment. However, the existing respirator is generally installed with a cylindrical filter inside the shell. The purpose of filtration is achieved after the airflow passes through the cylindrical filter body, but the above-mentioned filter structure generally cannot adjust the filtration accuracy, and different filter pores need to be adjusted according to the size of different impurity particles to achieve the purpose of efficient filtration, and the replacement of the filter body is inconvenient , affecting work efficiency. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a fi...
