Qu pressure filter is one relying on the pressure of wet sieving was subjected to high-efficiency screen. It consists of the screen surface, the screen box, feeders and export components. Screen surface pressure is a key component song screen. It consists of a stainless steel sieve sieve-shaped pieces assembled together. Wet material under pressure ejected from the nozzle opening 0.2-0.4Mpa operation. Feeding a high ejection speed tangential force generated. Triangular wedge-shaped pieces to form a screen edge to form a layer of the material wipes book book, water and fine material uniformly dispersed, the so-called "scraping" effect, is to make the material easy to grade, and the entire screen surface to be essential since clean up. Oversize material from the slag discharge port, the undersize material into a slurry outlet.
Conditions and factors that affect the screening effect:
Operating pressure must be controlled between 0.2 ~ 0.4MPa, high pressure, high screening efficiency, production capacity is also large, the pressure is low, the screening efficiency is low, productivity is also low. When screening feed dry matter content of about 17% fine slag first screening of starch milk. 10-11BX, SO2 content of the slurry should be between 0.035 to 0.045%.
Material: 316L or designated materials.
Performance parameters:
1、 the screen surface arc angle: 120 ° or specify radians
2、 the sieve slit width: 50um, 75um, 100um, 150um, 200um
3、 material handling capacity: 34 ~ 46m3 / h 4, feed pressure: 0.2 ~ 0.4MPa
5、the screen surface width: 585mm, 710mm, 825mm
6、 the screen surface radius: 762mm
7、using two-way screen surface, long service life.
