Safety protection mask for chemical industry processing

Abstract

The invention discloses a safety protection mask for chemical industry processing. The safety protection mask structurally comprises a mask body, a connector lug, a fixing block and a breathing tube, wherein the right side of the mask body is fixedly connected with the left side of the connector lug in an embedded mode, the fixing block is embedded into the front surface of the mask body, and the outer layer of the breathing tube is fixedly connected with the inner wall of the fixing block in an embedded mode. According to the safety protection mask, the coating structure is pressed by the air pressure generated in the process of sucking air from the outside, then a coating net is enabled to move downwards, an air pressing ball is pressed, so that the air pressure generated by the air pressing ball is upwards transmitted and injected into a scraping head, finally, a shovel head in a pressing head is expanded outwards through an outward expanding pipe to be bounced off, then dust attached to the top surface of the coating net is quickly shoveled up, repeated vibration is generated through inertia impact in the bouncing process, the shoveled dust is shaken off, during expiration, the shaken-off dust can be blown out through the outwards-scattered air flow, and the problems that the air permeability is reduced and the protection performance is reduced due to the fact that a large amount of dust is adhered to the coating net are effectively solved.

Description

technical field [0001] The invention relates to the field of industrial chemistry, in particular to a safety protective mask for chemical industry processing. Background technique [0002] Chemical industrial processing refers to the use of chemical reagents to corrode or corrode metal or glass workpieces with grinding, so that the workpiece can obtain the desired shape and smoothness. Due to the use of various chemical reagents in the process of processing, some chemical The reagent is harmful to the human body, and the operator needs to wear a safety protective mask to ensure safety. The safety protective mask reacts with the chemical reagent vapor through a special material coating net to make it become a harmless substance after the reaction. When the silicon wafers used for cement testing are chemically processed in the cement factory, due to the presence of a large amount of floating dust in the air, the floating dust in the inhaled air contacts with the coating net an...

[0002] Chemical industrial processing refers to the use of chemical reagents to corrode or corrode metal or glass workpieces with grinding, so that the workpiece can obtain the required shape and smoothness. Due to the use of various chemical reagents in the process of processing, some chemical The reagent is harmful to the human body, and the operator needs to wear a safety protective mask to ensure safety. The safety protective mask reacts with the chemical reagent vapor through a special material coating net to make it become a harmless substance after the reaction. When the silicon wafers used for cement testing are chemically processed in the cement factory, due to the presence of a large amount of floating dust in the air, the floating dust in the inhaled air contacts with the coating net and adheres to the coating net. At the same time, due to human Exhaled air contains water vapor, which can easily cause floating dust to condense on the coating net, and a layer of dust is attached to the coating net, which not only affects the ventilation effect of the mask, but also reduces the contact effect between the coating net and chemical reagents, making chemical reagents The reaction is not thorough enough, reducing the protective effect of the protective mask
