For viscous resin production
Scraper self cleaning filter is specially designed for high viscosity liquid filtration. It can automatically remove particles and impurities on the inner surface of filter screen through mechanical scrapping. It allows for continuously online filtration and is suitable for places where no additional substance for back washing can be introduced. We offer both inner scraper self-cleaning filters and outer scraper self-cleaning filters to meet a variety of challenges you may encounter in industrial production.
Inner scraper self cleaning filter is a kind of self-cleaning filter that is designed to remove impurities on the inner surface of filter screen through scraper rotation driven by motor or air cylinder. It applies to the filtration in medium and highly viscosity liquids. Both stainless steel sheet scrapers and stainless steel brush scrapers are available.
Features
The liquid flows in from the inlet (1), flows through the filter element and then flows out from the outlet (2). Impurities are trapped on the inner surface of the filter element. When impurities trapped on the surface of the filter element accumulate to a certain amount, the cleaning procedure is initiated by a timer setting or triggered by a differential pressure sensor. The speed reducer or cylinder (4) drives the scraper blades (6) attached to the surface of the filter element to rotate and scrap off the impurities. These impurities fall into the bottom of the filter. Drain valve (3) at the bottom of the filter shall be opened regularly to drain out the high concentration liquid for recycling.
Outer scraper self cleaning filter is a kind of self-cleaning filter that is designed to remove impurities on the outer surface of filter screen through scraper rotation driven by motor. It has a filter rating of 50–500 μm and applied to highly viscosity liquid filtration with high accuracy requirements.
Features
The liquid enters the filter from the inlet and flows through the filter element surface from outside to inside. The filter element bottom is connected to the outlet, through which the liquid flows out. When impurities trapped on the surface of the filter element accumulate to a certain amount, the cleaning action is triggered by the preset time or differential pressure value. The speed reducer drives the scraper blades attached to the surface of the filter element to rotate and scrap off the impurities. The impurities move off along the blades, fall down to the filter bottom and enters the particle collection cone. These impurities are collected at the filter bottom. Drain valve at the bottom of the filter shall be opened regularly to drain out waste liquid with high impurity concentration. Discharged waste liquid can be recycled if necessary.
Traditional manual filters are frequently clogged when filtering viscous materials and soft impurities, self-cleaning filters can easily solve such problems and always keep the filter element clean. As a result, self-cleaning filters can replace traditional manual filters in many fields.
