Introduction

Application Range of the belt press(roller press, press filter):

Belt press(roller press, press filter) is widely used for slag-water separation of all kinds of plant root stem, leaf, fruit, and efficient de-watering of all types of life and industrial sludge, including material de-watering of the vegetable leaf, vinasse slag, beer residue, manioc residue, sweet potato residue, corn residue, sugarcane residue, Chinese medicine residue, apple residue, pear residue, pineapple residue, tea residue, wood pulp fiber, paper pulp fiber, paper-making tailing residue, horseshoe residue, soybean residue, potato residue, household garbage, coffee residue and faeces, sludge, etc.

working principle：

The fine wet slag raw materials enter into the hopper constantly through screw pump or conveyor(the material belt width is adjustable). Firstly, materials pass through an independent concentrating section where most free water is filtered, thus reducing the sludge slag liquidity. Then materials go through two annular filter belts. Under the driving of the driving roller, materials are distributed evenly by the spiral material press roller. They begin to enter into the curved arc wedge area for initial pressing and de-watering. Next, they enter into low pressure area where the compression roller with a L type mound layer extrudes large amount of water, and makes sure that water is discharged from both sides. Then they enter into the butt clamping and extruding high pressure area, internal and external filter belts bypass several groups of butt clamping and extruding rollers of which the diameter is diminishing. Large amount of water is strongly extruded slowly, forming compressible filter cake. On the other hand, the filter belt twines in S shape, and produces increasing surface pressure and shear force. Under the filter belt tension effect, the pressure produced by outer layer filter belt squeezes a small amount of water in the water out. As the press roller diameter decreases gradually, the material pressure between the filter belt increases gradually, a small amount of water is discharged constantly. Large amount of water is discharged by strong clamp roller squeezing and pressing, then collected and discharged by the sink. After the inner and outer filter belts are separated, wear-resisting scraper device the scrapes the filter cake( pomace) on the working surface of the inner and outer filter belt after de-watering. In the end, high pressure solid cone convex shape cleaning nozzle forms fan crossing water belt, and washes mesh belt continuously, thus keeping constant de-watering effect.

Advantages：

We take customer’s satisfaction as a rule, combine traditional technology characteristic and ground-breaking innovation idea, and innovatively design with supplementary forward-looking technical idea. Besides, we improve every detail point strictly, making it to the point. The super-strengthened rigid-flex roller extruding effect makes the slag-sludge de-watering technology be improved essentially. Therefore, after being dried, extruded and de-watered strongly, the slag(sludge) cake water content reaches mechanical de-watering limit state, which is really remarkable achievement in mechanical de-watering field in domestic and aboard. The de-watered water content can reach 45-60%. Hourly processing capacity can reach 3-12 cubes. High automation degree, continuous operation for 24 hours.
