Fresh air system under dust environment

Abstract

The invention discloses a fresh air system under a dust environment. The fresh air system comprises a water tank assembly, an exhaust pipe, a filter net, an air filter, an exhaust pipe sealing sleeve,a diaphragm pump, a fresh air main pipe sealing sleeve, a fresh air main pipe, a fresh air branch pipe, a cut-off valve, a hose and a respirator. Air outside a dust workshop enters the diaphragm pumpthrough the air filter, air exhausted from the diaphragm pump enters the filter net through the exhaust pipe, bubbles crushed by the filter net enter clean water of a water tank body, the clean waterfully makes contact with the crushed bubbles to adsorb tiny dust particles in the air, the air is further purified and delivered to the respirator, the fresh air in the positive pressure state in therespirator is directly supplied to operators for breathing, thus the workers are prevented from inhaling dust, and the body health of the workers is effectively guaranteed.

Description

technical field [0001] The invention relates to a fresh air system, in particular to a fresh air system in a dusty environment, and belongs to the technical fields of environmental protection and electrical and electromechanical technology. Background technique [0002] With the continuous improvement of living standards, people's requirements for physical health are also constantly improving, but there are still many dusty workplaces, such as mining, cement, powder metallurgy, mining, grain, drying, polishing, grinding, etc., in such a long-term Working in such an environment can easily lead to lung diseases, such as silicosis, which is incurable. Contents of the invention [0003] In order to solve this problem, the present invention proposes a fresh air system in a dusty environment. The air outside the dust workshop enters the diaphragm pump through the air filter, and the air discharged from the diaphragm pump enters the filter screen through the exhaust pipe and pass...
