1、 Overview

CXSW Triple Networkbelt filter pressIt is a new generation of patented dewatering equipment developed and produced by our company through the introduction, digestion, and absorption of advanced technology from Finland. It has the advantages of large processing capacity, high dewatering efficiency (which can be directly increased from 0.8-3% slurry concentration to 28-35% or more), and low energy consumption. It not only solves the problem of material leakage that occurs when traditional double mesh filter presses dehydrate raw materials, but also solves the problem of low material pressure at both ends of the mesh. Due to the pre dewatering mesh of the new model, the natural gravity dewatering zone of the sludge has been extended, and the mesh is not easily blocked by fibers and sludge without being squeezed on the mesh. So compared to traditional filter presses, the net and amide usage are reduced by more than 10-30%, and the structure is simple and easy to install, making it an ideal product for sludge filter pressing, black liquor extraction, or slurry concentration.

2、 Structural features:

The Three Networksfilter pressIt consists of several rollers of different diameters and a mixing tank installed on a bracket. It is driven by a transmission roller and consists of upper (middle, lower) mesh, dewatering roller, tension roller, guide roller, correction device, and sealing device at both ends of the dewatering roller. The filter adopts compressed air pressure tightening to maintain a constant tension throughout the entire mesh belt, and will not cause changes in tension due to changes in the amount of feed; The machine is also equipped with a pneumatic deviation adjustment device, which is more convenient to operate and manage. The more novel and practical feature is that at least one or more dehydration rollers are equipped with sealing devices at both ends. The sealing device consists of a sealing belt and a roller that drives the sealing belt. The sealing belt is pressed on the horizontal ends after the upper and lower nets overlap, and there is a tension roller between the rollers. With the rotation of the dewatering roller, the sealing belt and roller wheel are driven to rotate, so that the slurry between the middle and lower nets is not only compressed by the dewatering roller, but also by the sealing belt, thereby strengthening the dewatering and sealing slurry.

3、 Working principle:

According to the different pressures in the dehydration zone, the entire dehydration process can be divided into three parts: the mesh pre dehydration zone, the pressure dehydration zone, and the pressurized forced dehydration zone.

The slurry is evenly distributed in the online pre dewatering area through the slurry distributor, and then enters the gravity dewatering area. The sludge in this area mainly relies on its own gravity to remove most of the water, causing the slurry to lose fluidity and the dewatering concentration to increase to 3-5%. Then continue dewatering on the middle net, and the slurry enters the wedge-shaped intersection area formed by the middle and lower nets, which is the pressure dewatering zone. The slurry is slightly compressed by the middle and lower filter screens in this area, dehydrated to about 15-20%, and then enters the pressurized dehydration zone. The pressure dehydration zone consists of 8 dehydration rollers of different diameters, which rapidly dehydrate both sides of the filter screen during the squeezing process. The arrangement of the diameter of the dewatering rollers gradually decreasing from large to small and the change of the filter screen angle ensure the formation of continuously increasing dewatering pressure and corresponding shear force, causing the slurry to repeatedly deform in the "S" - shaped dewatering zone and continuously remove moisture concentration of 28-35% or more to form a mud cake, which is then scraped off by a scraper. After removing the slurry, the filter screen is washed clean with high-pressure water and enters the next working cycle.
