Blue Star East Large Scraper Filter

The scraper-type self-cleaning filter is a precision device that uses a filter screen to directly intercept impurities in water, removing suspended solids and particles, reducing turbidity, purifying water quality, and minimizing system fouling, algae, rust, etc., to purify water and protect other system equipment for normal operation. Water enters the self-cleaning filter body through the inlet. Due to intelligent (PLC, PAC) design, the system can automatically detect the degree of impurity deposition and automatically discharge sewage through signals to the sewage valve. Product Features: 1. Strictly follows steel pressure vessel design standards, with production processes subjected to rigorous quality inspections, precision manufacturing, safe and reliable; 2. While filtering, combined with the ECS control system, it can set self-cleaning and self-sewage functions without interrupting the filtration process; 3. No easily worn or consumable parts, no frequent disassembly required, sealed filtration with no leakage risk, low power operation, and very low operating costs; 4. Unique intellectual property design, innovative product, easy and quick maintenance, standardized essence throughout the entire workflow, with no hidden usage costs; 5. A choice that replaces traditional filters and advances process efficiency.

 Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.
