Zusammenfassung: | The invention relates to a filtering device of an adhesive, comprising an adhesive kettle, an adhesive condenser, a filter and a material storage tank which are sequentially connected by virtue of pipelines, wherein the adhesive flow pipeline is provided with a flow regulating valve, the top of the material storage tank is sequentially connected with a gas condenser, a gas buffer tank, a gas absorption tank and a vacuum pump by virtue of pipelines, and all the components and pipelines form an internal enclosed space. The front end of the filter is provided with an adhesive condenser, so as toensure the viscosity of the adhesive to be appropriate before filtering, carry out high quality filtering and cause the adhesive to be filtered under a negative pressure condition, thus realizing high filter efficiency; and a negative pressure pipeline is utilized to recycle an organic gas volatilized in filtering process, thus almost realizing zero emission of toxic and harmful gases in production, effectively reducing e |
