Filtering device for adhesive

The utility model relates to a filtering device for adhesive, which comprises an adhesive reaction kettle, an adhesive condenser, a filter and a storage tank, which are connected sequentially by pipelines. An adhesive flowing pipeline is provided with a flow regulating valve. The top of the storage tank is connected with a gas condenser, a gas buffer tank, a gas adsorption tank and a vacuum pump sequentially by pipelines. An inner closed space is formed by all the components and the pipelines. In the utility model, the front end of the filter is provided with the adhesive condenser to guarantee that the adhesive has suitable viscosity so as to carry out high-quality filtration, therefore, the adhesive is filtered in the negative pressure state and the filtering efficiency is high. The same negative pressure pipeline is also utilized to recover organic gas volatilized in the filtering process. The zero emission of the toxic and harmful gas in the production process can be basically realized. The environmental
