Structure and application of belt press

      Working principle of press:

After elaboration of wet slag raw material (or solid-liquid mixture), straight into the hopper through screw pump or conveyor of bandwidth can be adjusted (material), both inside and outside two annular filters under the drive roller, composed of screw press roll uniform distribution, begin to enter the curved curved wedge zone, initial pressure dehydration, and then into the low pressure area, a zone “L” type layering of roller of a lot of pressure, water and ensure water discharge from both sides, then enter the extruding high to the clamp, diminishing belt around several groups inside and outside diameter of squeezing roller to the clamp, a large number of moisture was slowly of strong pressure, can press filter cake formation, on the other hand.

The filter belt is wrapped in the shape of “S” and produces shear force with increased surface pressure. Under the action of the tension of the filter belt, the outer filter belt produces pressure on the material to squeeze out a small amount of water in the material. As the diameter of the press roller decreases gradually, the pressure on the material between the filter belts increases gradually, and a small amount of water is discharged continuously.

A large amount of water in the material is squeezed out by the powerful pinch roller and collected and discharged through the connecting water tank. After the inner and outer filter belts are separated, the wear-resistant scraping device scrapes off the dehydrated filter cake (fruit residue) on the working surface of the inner and outer filter belts.

After that, the high pressure solid cone convex cleaning nozzle is used to form a fan-shaped cross water belt to wash the net belt continuously, so as to maintain the continuous dehydration effect.

Classification of presses.

1, according to the dehydration pressure is divided into: light roller belt press, heavy roller belt press, strong roller belt press.

2,According to the function, it can be divided into: monomer strong roller belt press, combined concentration press and integrated roller belt press, split type concentration and compression integrated roller belt type press.

3, according to the bandwidth is divided into 1 meters of strong roller belt type press,1.5 meters of strong roller belt type press,2 meters of strong roller belt type press,2.5 meters of strong roller belt type press.
