Abstract

The invention discloses a gas exhaust control system of a coating machine. The system comprises at least one section of oven, a wind circulating module, an exhaust module, a fresh air replenishing module, a control module and multiple sensors; the wind circulating module includes a circulating fan, a heating package, a pressure cavity and a wind nozzle mounted in the oven, and a pressure cavity wind door adjusting device; under the effect of the circulating fan, circulating wind enters the heating package through a circulating wind pipe for heating, enters the pressure cavity, and is sprayed out by the wind nozzle to dry a product; the fresh air replenishing module includes a fresh air replenishing pipe for connecting an intake port of the circulating fan with outdoor environment, and a fresh air replenishing valve adjusting device arranged on the fresh air replenishing pipe; and the exhaust module includes an exhaust fan, an exhaust wind pipe connected to an outdoor waste gas recovery system and an exhaust valve adjusting device. The system can realize automatic exhaust control over such combustible gas and harmful / poisonous gas as NMP in proportion of concentration.

Description

technical field [0001] The present application relates to a coating machine gas emission control system and a coating machine thereof. Background technique [0002] A coating machine is required in the production process of the battery, and NMP (methylpyrrolidone) is the main component of the battery slurry. It is a volatile organic solvent, flammable, explosive, corrosive and toxic to a certain extent. During the operation of the coating machine, the oven of the coating machine will volatilize the NMP components to form NMP gas during the drying process. When the concentration of NMP gas is not well controlled and reaches a certain concentration, there is a danger of explosion. The different concentration of NMP gas in the oven will affect the drying process of the coating and affect the drying quality of the coating. Contents of the invention [0003] In view of this, it is necessary to provide a gas emission control system for a coating machine and a coating machine th...
