Device for combining juice in a press

The invention relates to a device for combining juice in a press for squeezing out liquid-containing substances, namely agricultural and chemical products, with a closed container which can be set in rotation about its horizontal longitudinal axis, wherein a filling and emptying opening which can be closed by a lid is arranged in the container casing and at least one pressing membrane is arranged in the container which divides the container into a pressing chamber and a pressure medium chamber, and a juice drain is provided in the pressing chamber, and liquid-permeable pipes are arranged as drainage elements inside the container across the diameter and perpendicular to the container axis.

For example, a press is known (EP 0 145 948 B1) in which a number of liquid-permeable pipes are arranged in the pressing chamber in the diameter area of the container, whereby the liquid-containing substances are pressed out with the aid of a membrane and the pressed liquid runs off the juice outlet of the liquid-permeable pipes into a collecting trough arranged below the container. To collect this escaping juice, a juice collecting trough is provided, for example, which is attached to the container with the aid of hinges and which is sealed to the container in the closed position. On one side of this trough there is a juice outlet opening which can be closed with the aid of an opening flap which is operated by a pneumatic cylinder. The main disadvantage of this known device is that the structural design and the sealing are relatively

are complex and make the production of such a press considerably more expensive.

The invention is based on the object of designing a device for combining juice in such presses in such a way that the juice emerging at several points is guided to a single juice outlet opening using simple components, which can be easily sealed and closed for the pressing process and dismantled for cleaning purposes.

This object is achieved according to the invention in that in the area of the liquid-permeable pipes, closable collecting nozzles are attached to the outside of the container, which are connected by means of connecting pipes and the last collecting nozzle on the right or left side is provided with a control part as a juice drain.

An advantageous embodiment provides that a cleaning opening to the connecting pipes is provided opposite the juice outlet.

Furthermore, it is advantageous that the control part for the juice outlet has a box that can be closed by means of a drive cylinder, which can be moved back and forth on a tail pipe with juice outlet and, in one position, seals the juice outlet and, in the other position, releases the juice outlet.

It is further proposed that the collecting nozzles are each provided with a hinged cover which can be closed by means of a retaining screw.

The invention is explained in more detail in the following description using an embodiment shown in the drawings.

a representation according to Fig. 7 with a view of the juice drainage opening.

The press has an elongated cylindrical container 1 which has round bottoms 5 on both sides and which can be rotated about its horizontal longitudinal axis 2. Liquid-permeable pipes 4 are arranged transversely to the longitudinal axis 2 at a distance corresponding to the diameter of the container and one or more press membranes are located in the container 1 which divide the container into a press chamber and a pressure medium chamber. The liquid-permeable pipes 4 are located in the press chamber.

As an extension of the liquid-permeable pipes 4, collecting nozzles 6 are firmly attached to the outside of the container 1, e.g. by welding, and can be firmly closed using a cover 7 and a retaining screw 8. They are arranged on the edge of the nozzle 6 on a hinge 19. Furthermore, the individual collecting nozzles 6 are connected using connecting pipes 9, with a cleaning opening 15 being provided on one side of this connecting pipe 9, i.e. to the side of the last nozzle 6 in the row, and an end pipe 11 with a control part 10 for the juice drain being provided on the opposite end.

The control part 10 has a substantially square sliding box 12, which can be axially displaced with the help of a pneumatic cylinder 13 and is guided on the end pipe 11. A guide rod 14 serves as an additional guide for the sliding box 12, which is arranged on a holder 16, which also holds the pneumatic cylinder 13. On the outer transverse wall 20 of the

Inside the valve box 12 there is a circular seal 17 with a truncated cone-shaped attachment which closes the juice drain opening 18 in the closed position.

The cleaning opening 15 located at the opposite end of the device allows complete cleaning of the pipes 9, 11 from one end to the other. The individual collecting nozzles 6 can be opened and folded over without tools by loosening the retaining screw 8 in order to clean or dismantle the drainage elements or the liquid-permeable pipes. In the open position, the lids 7 snap into place on the hinges 19 so that no loose parts can fall down when the container 1 is rotated.

The juice flow at the juice flow opening 18 is controlled by the pneumatic cylinder 13, whereby in the closed position (Fig. 6) the juice flow opening 18 of the end pipe 11 rests against the seal 17. The slide box 12 is moved in the direction of arrow 21. To open the juice flow opening 18, the slide box 12 is moved in the opposite direction, direction of arrow 22 (Fig. 7), so that the seal 17 moves away from the opening 18 and the juice can flow unhindered into the interior of the slide box 12. The slide box 12 and the pneumatic cylinder 13 can be dismantled for cleaning purposes.
