Therefore, increasing the output of a single cycle means increasing the number of filter chambers and controlling the cost of equipment to form a sharp contradiction
[0009] 2) In the traditional filter press equipment, in the air dehydration step after the filter press step, after the injected air squeezes out a part of the filtrate in the filter cake, the filter cake becomes loose accordingly, that is, the filter cake appears gap, and the injected air can pass through the gap, so the filtrate cannot be effectively squeezed out, making the effect of air dehydration worse
[0010] 3) The traditional filter press equipment uses the feeding of each filter chamber in sequence, and the feeding is carried out sequentially from the filter chamber on one side to the filter chamber on the other side, so the feeding of each filter chamber is uneven
When the upstream filter chamber along the slurry flow direction is already full of solids, the downstream filter chamber is not yet full, which prolongs the operating cycle

Embodiment Construction
[0037] see figure 1, the solid-liquid separation filter press embodiment of the present invention shown therein includes a frame 100 . A fixed end frame 1 is installed on the frame 100 . The fixed end frame 1 is fixed relative to the frame 100 . The connecting pieces 11, 11' are respectively fixed on the fixed end frame 1 at points F1, F1', and can rotate around points F1, F1' respectively. The two ends of the cylinder 6 are rotatably connected to the connecting parts 11, 11' at points F2, F2' respectively. One end of the connecting rod 12 is connected to the connecting piece 11 at point F3, and the other end is connected to the movable end frame 2. One end of the connecting rod 12 ′ is connected to the connecting piece 11 ′ at point F3 ′, and the other end thereof is connected to the movable end frame 2 . A plurality of filter plates 3 , 4 are juxtaposed between end frame 1 and end frame 2 . Wherein the filter plate 3 is a perforated plate with a feed channel and a feed ...

The present invention provides a unique main pressure cylinder-link design scheme. Said invention also adopts auxiliary pressure cylinder, and its filtering chamber can be divided into several groups, when one group of filtering chamber is opened, other groups of filtering chamber can be closed by means of auxiliary pressure cylinder, so that the contradiction between pressure cylinder stroke and output can be resolved. Said invention adopts compressible filtering chamber, and its width can be regulated to extrude fiter cake to obtain air dewatering effect. Said invention also provides a novel filtering plate with composite structure.
Description
technical field [0001] The present invention relates to the solid-liquid separation technology of pressure filtration, and more specifically, the present invention relates to solid-hydraulic filtration separation equipment and method. Background technique [0002] In mining and environmental treatment, it is often necessary to separate the slurry formed by the mixture of solid and liquid substances, and filter press separation is a commonly used solid-liquid separation technology. In a traditional filter press, a plurality of filter plates are movably juxtaposed between the fixed end and the movable end of the filter press, and the movable end is moved by a press cylinder, thereby pressing all the filter plates together , thus forming a closed filter chamber between the filter plates. Then use the feed pump to drive the slurry into the filter chamber for solid-liquid separation. [0003] Solid-liquid separation is usually divided into press filtration, air dehydration, and...
