ENERGY-EFFICIENT OPERATION, LOW POWER CONSUMPTION
The Unite U-ZC-G2 series scraper filter is not only used for water filtration, but is also widely applicable to the self-cleaning filtration of viscous materials such as solvents, acids and alkalis, polymers, and coatings. It offers higher efficiency and a filtration range of 25-2500 microns, and can handle liquids with viscosities up to 5,800,000 centipoise. The Unite U-ZC-G2 series scraper filter is widely used in water treatment, petrochemicals, metallurgy, power generation, fine chemicals, coatings, inks, paper manufacturing, food and beverages, pharmaceuticals, metal processing, and other industries.
1. Fully automatic operation, 24-hour continuous online filtration, eliminating the laborious work of filter element replacement and cleaning;
2. Utilizes metal or PTFE scraper blades for excellent scraping effect, significantly improving impurity removal and preventing the crushing of impurities;
3. Backwashing function can be added to assist in cleaning the filter element;
4. Small footprint, saving on consumables and environmental treatment costs;
5. Low filtration pressure drop and stable flow rate, facilitating continuous and stable process operation;
6. Closed filtration prevents leakage of hazardous materials, contributing to safe production and employee health;
7. High concentration of discharged waste impurities, which can be recycled, reducing the loss of high-value materials;
The liquid flows in from the inlet, flows outward from the inner surface of the filter element, and exits through the outlet connected to the lower end of the filter element. Impurity particles are intercepted on the inner surface of the filter element. When a certain amount of impurities accumulates on the filter element surface, a cleaning procedure is initiated either periodically or based on a set pressure difference. A geared motor/cylinder drives scraper blades attached to the filter element surface to rotate, scraping away impurities from the inner surface of the filter element. The impurities leave the filter element surface along with the scraper blades and fall into the bottom of the filter with the downward-flowing liquid. A rotating sweep plate sweeps the heavy impurities at the bottom into the sludge chamber. The impurities accumulate in the sludge chamber and at the bottom of the filter. The drain valve opens periodically, discharging the high-concentration liquid containing impurities from the drain port, which can then be recycled.
Fluid enters the filter and solid particles are captured by the filter element.
When preset pressure or time is reached, the system automatically initiates backwashing.
Removed particles are flushed out through the drain outlet.
Differential pressure is continuously monitored to detect filter contamination.
Clean fluid flows in reverse direction to remove trapped contaminants from the filter surface.
The system resumes normal filtration without interrupting operation.
