PATENT OFFICE.

This invention relates to filter presses used for making pottery clay or for pressing yeast or paraffin or other semi-liquids, and at which porous inserts are used, through which the liquid constituent • the semi-liquid is pushed through.

The essence of the invention is that the porous inserts are removed and can be turned over, so that the liquid component goes in opposite directions occurs through the deposits. This prevents the pores of the inserts from opening clog by the solid components.

The filter press consists of parts, each of which is formed from two or more plates of suitable strength, which are placed in wooden or other frames. These parts are bolted to one another or braced laterally in some other way in such a way that free spaces remain between the individual sets of plates. The surfaces of the. Plates are suitably grooved and hollowed to allow the liquid to pass through. In the drawing five such parts are shown, which are designated A ¹ A ² A ³ A * A ⁵ . Each part consists of two frames B respectively. C, and each frame carries 12 porous plates d (the number of these can of course be different). One of these frames is shown in FIGS. 5, 6 and 7. The sides of the frame are ^{enclosed by square bolts e 1} e ² e ³ e ⁴ , which are weakened at the end in order to pass through a corresponding hole in the next bolt, so that the inserts d are firmly clamped after tightening the bolt frame.

The longer sides of the frame are reinforced by the cross connection e, Fig. 5, which goes through the frame. Each of the shorter sides has a central pin f, which bezw with the bolts e ^3. e ⁴ is forged from one piece. As can be seen from Fig. 4, the porous inserts with grooves. provided on each side, suitably running in opposite directions, so that when they are put together in the frame, the grooves on one side of the

5 and 6. When the two frames B and C forming a part are brought together, the channels on the adjacent faces of the plates in frames B and C run at right angles against each other. So are z. B. the grooves in frame B vertical and those in frame C horizontally, so that the liquid which runs through the plates is guided along the grooves and emerges at the lower edge. Between each of these parts there is provided a clay frame G, which is designed according to the frame intended to receive the porous inserts and is provided only on its upper side with a small tube g through which the muddy or semi-liquid mass enters the frame. Each of these pipes g is provided with a tap h and connected to a flexible pipe j which connects to the main pipe k , which supplies the semi-liquid to the filter press. The clay frames and the frames with the porous inlays are supported next to each other by their tenons / resting on each side between guides /. The same are in this case formed by tie rods, by means of which the two end plates w} m ^{2 of} the press are held together. These end plates Vi ¹ WL ² are supported by a suitable bracket η . 0 is a pressure plate, which is also carried by the side guides ZZ and in this case with two pairs of toggle levers ρ as well as with nuts and right and left-hand thread screwj? ^{2 is} provided. This mechanism is analogous to the similar devices found in known filter presses. Instead of the screw with right-hand and left-hand thread and the knee joint lever, any other suitable mechanism can also be used to move the pressure plate 0. In the case of the press shown in FIGS. R and 3, only a few frames are indicated, which of course are to be attached in such a number that the space between the plate m ¹ and the pressure plate o is filled, then the pressure plate 0 is advanced so far that the frames are clamped tightly together. The contact surfaces of the frames are provided with grooves all around at q , which serve to accommodate round packing strips made of rubber, etc., in order to form a tight connection between the clay frame and the frame carrying the porous inserts. A pack between two frames with porous inserts, however, is not provided; the surfaces of these frames are provided with transverse grooves which allow the liquid to escape. The muddy or other semi-liquid is driven through the pipes g into the clay frames G or spaces between the parts of the porous pads, through which the latter the liquid passes and runs along the channels between the pads to exit between the frames B and C , with clay or other solid bodies are retained in the spaces between the parts of the porous inlay. When these spaces are filled with the solid mass, the pressure plate 0 is screwed back so that the frames can be separated from one another. The solid material to be pressed is then removed and, before the frames are adjusted again, the frames with porous inserts are turned halfway around, as can be seen from FIG . By means of this device, when the cavities are filled again with the semi-liquid, the pores of the inserts are opened for the liquid parts which pass through the inserts in the opposite direction, and clogging of them is prevented. The porous inlays are very easy to make from ordinary clay, as it is for brick production is used. The clay is with a certain percentage ' To mix in coal dust or sawdust and then to shape. By burning the coal dust or sawdust is consumed and the panels acquire a high porosity. However, the insert plates can also be produced in other ways. In order to be able to move the frame for the porous deposits and the clay frame parallel along the guides by a man standing to the side of the press, the ends f ^{1 of} the pin f, as shown, can be somewhat weakened and hooked with the ends of Ropes are connected, one of which is provided on each side of the press, and which are guided to the same side via guide rollers. More than two frames for porous inserts can also be used for each prefecture and instead of arranging the frames vertically, you can also use them horizontally over attached to each other. Godfather ν τ claims: ι. A filter press in which the clogging of the porous inserts is prevented by the fact that the filter parts A ¹ A ² A ^s alternating with the spaces G for the semi-liquid . . . two or more porous plates arranged next to each other that can be turned over against each other, so that the liquid in the material to be pressed penetrates the plates alternately in opposite directions.
In the case of filter presses under i. characterized by the special construction of the filter parts, each of which is made up. two similar reversible frames AB , the pins f of which are movable along guides Z, and which contain the porous inserts d with channels directed in opposite directions, the frames G, which are also supported by pins / and adjoining the filter parts, are arranged between the latter. For this purpose 2 sheets of drawings.
