ZHR series pneumatic scraper self-cleaning filter

ZHR series pneumatic scraper self-cleaning filter (hereinafter referred to as ZHR filter), is nine for the company independent research and development of new high efficient scraper type self-cleaning filters, driven by cylinder annular scraper, scrape up and down in addition to the impurity particles on the surface of the filter in the yuan, is suitable for low viscosity liquid and high precision filter, can efficiently clean shave their various impurity particles, continuous on-line cleaning, through the PLC control of time/differential pressure control, automatic drain set the dirt cavity body contains a high concentration of impurities, suitable for water and various viscous liquid filtration.

ZHR filter is suitable for solvent, acid, alkali, polymer, coating, fermented liquid viscous materials such as self-cleaning filter, higher efficiency and little pressure loss of the filter, flow stability, save energy consumption of pipeline, is advantageous to the process continuous and stable. Apply to oil, paper, fine chemicals, paint, ink, food and beverage, biological fermentation and other industries.

The liquid passes through the filter inlet, and the liquid flows through the filter screen from the outside of the filter element to the outer surface of the filter. When the external surface of the filter element to collect a certain amount of impurities, the differential pressure value, ring type scraper is cylinder driving slowly downward shave their filter element surface impurities, to set the dirt cavity, inching up further scrape impurities, this part of the impurity with the descending liquid through a ring type scraper gathered in the collection chamber. When a certain amount of impurity is accumulated, the automatic drain valve will open the collecting chamber and expel the liquid containing high concentration of impurities, which can be recycled or discharged.

• Fully automatic operation, through PLC control time/pressure difference control, continuous 24 hours of online filtering, no filter consumption, no manual cleaning, cost saving and environmental protection.
• The filter pressure loss is minimal, the flow rate is stable, and the energy consumption is saved, which is beneficial to the continuous stability of the process.
• It is fully enclosed filter to prevent leakage of dangerous material, which is beneficial to safe production.
• It adopts unique v-slot filter element, with unique filtering surface structure, excellent scraping effect, uniform and uniform filter opening clearance, which is solid and durable.
• The unique PTFE ring scraper is used to remove impurities, and it is good at filtering viscous liquid.
• The concentration of impurities is high and can be recycled to reduce the loss of high value materials.
• Various control systems can be selected, powerful and efficient operation, which can meet the requirements of customers.
• A variety of modular combinations and powerful automation modes can be selected to meet various filtering requirements.
• Many international famous brand components, high reliability, low operating cost. Compact structure, small return clearance, high precision and bearing capacity, long service life.
• The structure is simple, easy to disassemble and easy to clean.

• Unique filtering surface structure, with excellent scraping effect, uniform and uniform filtering aperture clearance, solid and durable, high efficiency and stability.
• It is made of 304/316 materials, with excellent pressure resistance, aging resistance, acid and alkali resistance and corrosion resistance.
• It has a smooth surface inside and outside. It has very little wear and tear on the scraper.
• High mechanical strength, can withstand greater pressure difference.
• It can improve the regeneration ability of anti - washing.
• There is no particle blockage, and the anti-flushing energy can be gathered during backwashing.

• Applicable fields: biological fermentation, food and beverage, bio-pharmacy, ink, coating, etc.
• Applicable liquid type: amino acid, threonine, citric acid, fermented liquid, chitosan, sorbitol, steroids, corn syrup, food and beverage, cheese, paint, resin, polymer, etc.
