The main factors affecting the processing capacity of belt filter press

      Gravity dewatering zone: the flocculated sludge first enters the gravity dewatering zone, and most of the free water produced by flocculation needs to be removed in this zone.

Therefore, gravity dehydration zone is one of the main factors affecting the processing capacity of belt filter press.

In the gravity dewatering zone, the flocs are deposited on the filter zone, and the free water needs to be removed through the flocs through the filter zone, which puts a great burden on the gravity dewatering zone with limited length. Therefore, the efficiency of the zone should be greatly improved under the premise of the whole machine size and the length of the gravity dewatering zone being unchanged.

Eight, wedge type dehydration zone: with the operation of the filter belt, the sludge into the wedge type dehydration zone, wedge type zone has the dual role of gravity dehydration and press dehydration, so, wedge type zone is also one of the main factors affecting the processing capacity of the belt filter press.

As is known to all, when the sludge is still in the free gravity dehydration has stronger flow state, if put pressure on its suddenly, is bound to cause sludge to pressure point spread around quickly, if the Angle is large, composed of two filters that sludge suddenly into the extrusion department, composed of two filters are inevitably causes from outside the filter belt on both sides of the discharge has “sludge” phenomenon.

If handled improperly, the whole dehydration process will be disturbed.

The length of the wedge Angle should be considered in combination with the length of the gravity dewatering zone, the speed range of the filter belt operation, the permeability of the filter belt, the length of the wedge type zone, and the larger processing capacity of the belt filter press design.

Should guarantee that can accept large sent of sludge gravity dehydration, and can make the sludge in the wedge area as early as possible to accept slowly increasing, the sludge to the filter belt on both sides of the diffusion trend of spillover of tiny preloading, remaining free water in the sludge removal amount can completely satisfy the requirements of sludge thickening and hardening gradually, so as to smoothly transition to the press area.
