Scraper filter is a common filtering device, which works by using a scraper to scrape off the dirt on the filter screen, thereby achieving the purpose of filtration.
The main components of a scraper filter include a filter screen, scraper, scraper bracket, scraper drive device, etc. Filter screens are usually made of stainless steel wire mesh or polyamide mesh, and their pore size can be selected according to different filtration requirements. The scraper is a key component for removing dirt from the filter screen, usually made of stainless steel or polyurethane material. The scraper bracket is used to fix the scraper and ensure its stability during the filtration process. The scraper drive device is the power source of the scraper filter, usually using a motor or pneumatic device.
The working principle of a scraper filter is that the liquid enters the interior of the filter through the filter screen, and the dirt on the filter screen is scraped off by the scraper and falls into the bottom dirt collector. The clean liquid then flows out from the outlet. When the accumulation of dirt on the filter screen reaches a certain level, the scraper drive device will start, and the scraper will begin to scrape off the dirt on the filter screen, causing it to fall into the dirt collector.
The scraper of the scraper filter can be adjusted as needed to ensure a tight contact between the scraper and the filter screen, and to achieve good scraping effect.
Scraper filters have the advantages of high filtration efficiency, high filtration accuracy, and easy operation, and are widely used in the field of liquid filtration in industries such as chemical, food, and pharmaceutical. Meanwhile, the scraper filter can also be customized according to different filtration requirements, such as adding multiple layers of filter screens, installing automatic cleaning devices, etc., to meet the filtration needs of different industries.
