Abstract

This utility model discloses a plate and frame filter press for coal preparation, belonging to the field of coal slurry water treatment technology. It includes a frame with two sets of crossbeams fixedly connected to it. A base plate is also fixedly connected to the bottom of the frame. A filter pressing mechanism is installed at the top of the frame, and a collection box is placed on top of the base plate. A crushing mechanism is installed between the filter pressing mechanism and the collection box. The crushing mechanism includes a guide shell fixedly connected between the frames. The guide shell is funnel-shaped with a small opening facing downwards. Two sets of rotating shafts are rotatably connected between the inner walls of the guide shell. Crushing rollers are fixedly connected to the rotating shafts. The crushing mechanism also includes a power component for driving the two crushing rollers to rotate. The beneficial effect is that by driving the two rotating shafts to rotate the crushing rollers through the power component, the falling filter cake is crushed, reducing the space occupied by the filter cake and improving the utilization rate of the collection box.
