PATENT OFFICE.

CLASS 12 tfi 'GROUP

By the patent 195124 is a method for Removal of residue from the chambers of filter presses has been protected on its Implementation relates to the present invention. The procedure of the aforementioned patent requires that a rotatable liquid jet is provided in each individual filter chamber, which has the intended effect, namely the removal of the filter residues, by means of washing out safely reached by liquid, steam or gas. The present invention brings about a particularly simple and appropriate one This object is achieved in that the cleaning agent is rotatable inside or outside the filter chamber Pipe is fed, from which after each filter chamber through a suitable opening Beam branches off.

The method of the main patent also requires that the inlet openings for the movable Liquid jet are arranged in the vicinity of the outlet openings. This one Requirement corresponds to the embodiment according to the invention in that the conduit pipe of the cleaning agent is arranged in the outflow channel.

Both ideas of the invention are shown in several embodiments in seven figures.

Fig. Ι is a vertical cross section of one of the improved filter chamber arrangements according to the line / - / of FIG. 2.

Fig. 2 is a vertical cross-section along the line i-i of Fig. 1 and represents a series vertical filter chambers that are connected together.

FIG. 3 is a vertical section of another embodiment of the improved filter chamber taken along line LL of FIG. 4.

Fig. 4 is a vertical section along the line KK of Fig. 3 and shows a group of filter chambers which are connected together.

FIG. 5 is a vertical cross section of another modified form of filter chamber taken along line NN of FIG. 6.

Fig. 6 is a vertical section along line MM of Fig. 5 through a group of such filter chambers which are connected together.

FIG. 7 is a similar vertical section showing the rotating feed line in FIG other position.

The same letters refer to the same parts throughout the drawings.

In the execution of the filter chambers, as shown in Fig. 1, 2, 3, 4, 5, 6 and 7, χ represents the frame of the filter chamber, which can be of any cross-sectional shape

Claims (2)

can. 6, 6 are openings in the side walls; A series of filter chambers is put together, in which the filter press forms an uninterrupted channel that goes through the entire press and is closed at the ίο ends in any suitable way. The channel opens into any suitable container, α is a corresponding inlet to treat the precipitate with liquid, vapor or gas. Such an inlet can be located at each of the upper corners of the filter frame and forms an uninterrupted channel when the filter chambers are assembled in the filter press, i.e. an inlet opening through which the material to be filtered is introduced. This inlet is similar in design to the others and also forms an uninterrupted channel when the filter chambers of the filter press are assembled. This channel is provided with openings 9, 9, 9, from which the material enters the filter chamber, w is a feed line through which liquid, vapor or gas under pressure for the purpose of suppressing the precipitate is introduced. This line is provided with a nozzle, slot or hole y which is directed into the interior of the chamber. g is the filter frame, which is arranged between the filter chambers. 7 is a closure which serves to close the openings 6,6. In the second embodiment, which is shown in FIGS. 3 and 4, the opening 0 is arranged in the interior of the filter chamber and the supply line w, which can be attached immovably or rotatably, to the line w in FIG. 1, is arranged in it and corresponds to 2 and how this is provided with nozzles y, y. These go into each filter chamber, of which, as in the previous case, a number is used. d denotes the inlet through which the material to be filtered is introduced. In the third embodiment, which is shown in Figs. 5, 6 and 7, the precipitation is carried out through a series of openings 11, and a rotatable conduit w is provided which is provided with nozzles y, y so that when closures 12 are opened, the cleaning material can be fed from the line w to the chambers. In each of the embodiments, outlets 8, 8 are provided for the outflowing liquid, vapor or gas. . . . Godfather ν T-A ν Proverbs: 1. Apparatus for carrying out the method of removing the solid and semi-solid Residues from the chambers of filter presses according to patent 195124, thereby characterized in that the cleaning agent (liquid, steam or gas) by an inside or outside the filter chamber rotatable tube is fed, from which after each filter chamber a jet through a suitable opening branches off. 2. Embodiment of the device according to claim 1, characterized in that the pipe of the cleaning agent is arranged in the outflow channel. For this purpose ι sheet of drawings.
