[0002] A class of organic or inorganic synthetic substances that artificially connect the same or two or more homogeneous or heterogeneous parts (or materials) together and have sufficient strength after curing are collectively referred to as synthetic adhesives or synthetic adhesives. The subsequent production requires the use of a steel belt granulator. The working principle of the steel belt granulator is that the material is evenly sprayed on the granulation steel belt through a granulation distributor to form granules, and finally form flaky granules, which are then packaged. When small packaging equipment is used to package powder products, dust and floating particles will be generated, so an industrial dust collector is required. One of the commonly used means in the industry is a bag dust collector, such as the disclosed patent CN202121962241.6, an assembled packaging machine bag dust collector, the core of which is external filtration dust removal. However, the adhesive particles need to pay attention to the characteristics of the compound in dust removal. The outside of the filter bag is easily coated after aggregation, and the effect of the backblowing scheme is not very ideal. Therefore, in combination with the above-mentioned problems, a combination of scraping and backblowing is adopted to ensure efficient dust suction and discharge small particles and dust, and a dust removal device is proposed.
