Fire retardant device for mica tape production and method thereof

Abstract

The invention relates to a fire retardant device for mica tape production and a method thereof. The fire retardant device comprises a fire retardant cavity and a gas storage tank, wherein one side of the fire retardant cavity is provided with a mica tape feed port, and the other side of the fire retardant cavity is provided with a mica tape discharge port; nitrogen is stored in the gas storage tank, a nitrogen pipe is arranged on the gas storage tank, one end of the nitrogen pipe communicates with the gas storage tank, the other end of the nitrogen pipe extends into the fire-retardant cavity, and a plurality of nitrogen nozzles are arranged on the nitrogen pipe extending into the fire-retardant cavity; a normally-closed electromagnetic valve is arranged on the nitrogen pipe, and when the normally-closed electromagnetic valve is opened, nitrogen in the gas storage tank is sprayed into the fire-retardant cavity through the nitrogen pipe, the normally-closed electromagnetic valve and the plurality of nitrogen nozzles; and a flame detector is installed on the upper portion of the side, located at the mica tape discharge port, of the fire retardant cavity and connected with the normally-closed electromagnetic valve to control opening and closing of the normally-closed electromagnetic valve. According to the invention, the fire retardant effect is effectively achieved, and the safety of the whole mica tape production line is improved.

Description

Technical field: [0001] The invention relates to a fire arresting device for mica tape production and a method thereof, and belongs to the design field of fire arresting devices for mica tape production. Background technique [0002] The main structure of mica tape production line is composed of feeding area, dipping area, infiltration area, drying area and winding area. device, dipping device, permeation device, drying device, winding device, and an oven is installed on the drying device; since the dipping area uses toluene, a hazardous chemical, and is affected by high temperature during drying in the drying area, To a certain extent, it will cause deflagration of volatile combustible gas inside the oven. After deflagration inside the oven, it will quickly spread to the penetration area and dipping area, resulting in a fire accident. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fire arresting device and m...
