Two or more water guide cups 4 can be arranged on two sides of the water guide cup. Each water guide cup 4 is a hollow funnel-shaped cup which is vertically arranged and has two open ends. When filter pressing is carried out, each layer of filter pressing plate can be tightly attached to and extrude sludge, the water guide cups 4 at corresponding positions on the filter pressing plates on adjacent layers can be sleeved to form coaxial drainage pipelines to discharge sewage outwards, the drainage pipeline is not required to be arranged on each layer of filter pressing plate, and the filter pressing device is simple in structure, low in cost and high in reliability.
And the other two opposite outer side surfaces of the bottom plate 11 are respectively provided with an electric roller 5 and a driven roller 6. The electric roller 5 is used for driving the filter cloth 7 to move.
As shown in fig. 3, the arrangement form of the filter cloth 7 is: the water-permeable plate is drawn from the lower part of the electric roller 5 of one layer of the filter pressing plate to the outer side of the driven roller 6 of the next layer of the filter pressing plate, wound above the layer of the water-permeable plate 2 from the lower part of the driven roller 6, extended above the layer of the electric roller 5 and finally led to the next layer of the filter pressing plate from the lower part of the layer of the electric roller 5; and is wound in an S-shape between the filter press plates in this manner. A filter cloth 7 is used and driven by a speed reducing motor, so that the filter cloth can be unreeled and reeled when the filter pressing plate is opened. The filter cloth 7 is wound by S-shaped cloth, and all the filter pressing plates use one whole filter cloth, so that the filter cloth can be tensioned at one time, is convenient to replace and can be cleaned more conveniently.
In some embodiments, a sealing ring 3 is disposed at the bottom of the filter press plate frame 1. When the upper and lower layers of filter pressing plates are folded, the upper sealing ring 3 is pressed on the lower layer of filter pressing plate and keeps sealed.
