Press assembly for extracting liquids from solids

A press assembly for extracting liquids from solids;

• the press assembly comprising:
• a plurality of parallel spaced apart horizontally extending support rods;
• a plurality of press racks mounted on the parallel support rods for sliding movement relative to each other, each press rack being of a plate like construction;
• a plurality of filter bags supported by and between adjacent press racks;
• force applying means for moving the press racks towards each other with sufficient force to squeeze liquid from solid materials received within the filter bags supported between the press rack;
• collector means disposed below the press racks and capable of collecting liquids which are squeezed from the material received within the filter bags, the collector means including first and second collector troughs which extend in a direction parallel to the spaced apart horizontally extending support rods, each through having sides parallel to the spaced apart horizontally extending support rods, the collector troughs being mounted for pivotal movement and the troughs being movable between a normal position where they are spaced below the filter bags to an inoperative position where they are spaced to the sides of the filter bags, each trough having a lip on the side adjacent the other trough, the lip of one trough overhanging the lip of the other trough when it is in the normal position of the troughts;
• and
• collector moving means for moving the first and second troughs between the normal liquid receiving position to an inoperative position.

A press assembly for extracting liquids from solids;

• the press assembly comprising:
• a plurality of parallel spaced apart horizontally extending support rods;
• a plurality of press racks;
• means slidably mounting the press racks on the parallel support rods for only sliding movement on the support rod;
• mean mounting the support rods and press racks for rotation from a normal position to an inverted position;
• a plurality of filter bags supported by and between adjacent press racks, the bags having open tops when the press racks and support rod are in their normal position;
• force applying means for moving the press racks towards one another to squeeze liquid from solid materials received within the filter bags supported between the press racks;
• collector means disposed below the press racks and capable of collecting liquids which are squeezed from the material received within the filter bags as the press racks are moved towards one another;
• conveyor means disposed below the press racks and capable of conveying press cake;
• inverting means for rotating the press racks and filter bags from the normal position to an inverted position;
• and
• vibrating means mounted below the press racks, the vibrating means including a pair of spaced apart bars which parallel the support rods, the spaced apart bars being spaced apart a distance greater than the width of the filter bags but less than the width of the press racks so that the bars may contact the racks during filling and whereby, when the press racks are inverted, the press cakes will not hit the vibrating means as they fall from the filter bags.

A press assembly for extracting liquids from solids;

• the press assembly comprising:
• a press frame including two generally horizontal spaced apart parallel frame members and a transversely extending frame extending between the two spaced apart parallel frame members, the transversely extending frame functioning as a first abutment and being provided with a first bearing block;
• a first thrust bearing carried one face of the transversely extending frame;
• a first platen in juxtaposition with the first thrust bearing, the first platen having a first shaft rigidly secured thereto, the first shaft passing through the first thrust bearing and being journalled within the first bearing block;
• a plurality of parallel spaced apart generally horizontally extending support rods secured to the first platen;
• a second abutment carried by the spaced apart frame members for sliding movement thereon, the second abutment being provided with a second bearing block which is coaxial with the first bearing block;
• a second thrust bearing carried by that face of the second abutment on that side which faces the first abutment;
• a second platen in juxtaposition with the second thrust bearing, the second platen having a second shaft rigidly secured thereto, the second shaft passing through the second thrust bearing and being journalled within the second bearing block, the second platen being provided with plurality of parallel spaced apart bearings which received the plurality of spaced apart horizontally extending support rods for sliding movement thereon;
• a plurality of press racks;
• means slidably mounting the press racks on the parallel support rods between the first and second platens for only sliding movement on the support rods;
• a plurality of filter bags supported by and between adjacent press racks;
• and
• force applying means for moving the second platen towards the first platen with sufficient force to squeeze liquid from solid materials received within the filter bags.
