Stainless Steel Wedge Wire Screen Static Sieve Bend Filters

Stainless Steel Wedge Wire Screen Static Sieve bend filters are divided into two types: pressure curved sieves and gravity curved sieves.

Processing principle and structure:
The pressure curved screen is an efficient screen that relies on pressure wet material to screen. It consists of a screen surface, a screen box, a feeding device and an outlet. The screen surface is the key component of the pressure curved screen. It is assembled by stainless steel sieve-shaped sieve bars. During operation, the wet material is sprayed from the nozzle under the pressure of 0.2-0.4Mpa. Triangular sieve wedge strips form a knife edge to scrape the material into a thin layer, so that the water and fine materials are evenly dispersed. The so-called "scraping" effect is to make the material easy to classify, and the entire screen surface is self-cleaning. The screened material is discharged from the slag outlet, and the screened material enters the slurry outlet.

Process conditions and factors affecting the screening effect:
The operating pressure is controlled between 0.2 and 0.4 MPa, and the pressure is high, the screening efficiency is high, and the production capacity is also large. If the pressure is low, the screening efficiency is also low, and the production capacity is also low. When sieving, the dry matter content of the feed is about 17%. 10-11BX, the SO2 content in the slurry should be between 0.035~0.045%.
Material: 316L or selected material.

Performance parameters:
1. The arc angle of the screen surface: 120A or selected arc
2. Screen width: 50um, 75um, 100um, 150um, 200um
3. Material handling capacity: 34~46m3/h4, feeding pressure: 0.2~0.4MPa
5. Screen width: 585mm, 710mm, 825mm
6.The arc radius of the screen surface: 762mm
7. The screen surface can be used in both directions and has a long service life.

Factors affecting screening efficiency:
1. The size of the feeding pressure. The feed pressure should be 0.2~0.4MPa. The higher the pressure, the higher the screening efficiency, and the lower the pressure, the lower the screening efficiency.
2. The arc surface of the nozzle and the sieve should be tangent. If the installation accuracy is too poor, it will not be possible to produce the cutting effect, so the screen surface will not be able to screen the material, or the movement of the material is blocked and the direction of movement is changed. At this time, the screen surface will also lose the function of screening the material.
3. The effect of the fine grinding process before the sieve: it cannot be ground too fine, otherwise the ground slag particles will enter the starch milk together with the starch granules, which will increase the slag content in the starch milk.
