PATENT OFFICE.

CLASS 85: aqueduct.

The patent no. 58999 described Filtrir device is modified according to the present invention so that the top and bottom closed filter bodies in an open one Vessels are arranged in a straight shape next to each other, whereby they are the Take up the filtrate extracting tubes while the dissolved paper fiber or a other fibrous material suitable for filtering outside the filter body for deposition on the latter or flushing out of the apparatus, tubes in a straight shape between the filter bodies are arranged.

By the arrangement, the advantage of the main patents becomes very extensive Filter areas in a relatively small to gain cubic space while maintaining the construction of the apparatus and its operation, as well as the possibly necessary replacement of the filter body is essential simplified.

In the case of the present amendment, the device is still in place, the filtrate at the beginning of the filtration process, when the filtration layer has not yet been fully formed and therefore the filtrate is not yet completely clear, to be discharged separately until complete Clarity is achieved, whereupon another gutter is used to drain.

The modified apparatus is shown in a view in FIG. 1, and in FIG. 2 in a longitudinal section along XYZ of the basic plan in FIG.

The Filtrirapparat consists of an open vessel a, into which with appropriate spaces between each other between guide ^{strips a l} frames r are inserted standing vertically, which are clad ^{on both sides with metal sieves s 1} s ^2.

In each of the filter bodies s formed by such a frame with sieve sides there is a perforated tube t whose end located in the filter body is closed, while the other end, through the frame r as well as through the wall of the vessel α , enters the closed one Rinne ν empties.

Between each two of these inserted frames r there is a tube n provided with upwardly directed holes at the bottom of α , into which air can be blown through valve g and tubes h I after the steam jet blower i has been switched on.

The filtration device is operated as follows.

The container α is filled with the water to be filtered through channel c , then the further water supply is temporarily interrupted and, while the tubes y and jr ^{1 are} in the position illustrated in the drawing, a quantity of well-dissolved paper fiber or another is added Filter suitable fibrous material into the water, whereupon by means of the steam jet blower i forcefully through the perforated pipes η air into the loading

can be blown in container α . Fiber and water are so intimately mixed with each other. Then you close the steam valve k respectively. Air valve g, and after the water supply through channel c has been switched on again, pipe j ^, which can be rotated around its own axis at χ and λ: ¹ , is turned downwards so that its contents are emptied into channel w.

As a result of the rapid drainage of water, the filtrate fibers that are added to the water are now formed. within a few minutes on the sieve surfaces of the frame r seal the inner frame spaces against the container a , which the water must pass through. The filter surfaces formed in this way hold back all impurities in the water, so that only completely purified water can escape through the perforated pipes t to the collecting channel ν and pipe y.

Since it takes a few minutes for the Filtrirfilz to form completely closed by the water flow entering the Filtrirkörper, the drainage channel n> is arranged for the not yet completely clarified water that escapes during this short time.

But as soon as the felts are formed and abfiiefst the water clear, rotating the Rohrj ^ in such a manner that water is drained that after groove v ¹ in which it is supplied to its use.

If a certain amount of sludge has been deposited, the filters will probably stop working, but they will never let dirty, incompletely clarified water through, there A gradual pressing through of the dirt is excluded due to the type of filtrate formed is.

The cleaning of the Filtrir device is done done in the following way:

You shut off the water supply to the container a and open the steam valve k respectively. Air valve g, so that it is forcefully blown into α through the perforated tubes , then rotates the tube jr ^l, which is rotatable about its axis, towards channel m in such a way that the entire contents of a together with the filter masses loosened from the sieve surfaces by the blow-in the apparatus and through channel m into fabric boxes lined with a sieve. The mass deposited in the latter is then washed out in a washing machine or other washing machine and can be used again without further ado.

From the basic plan, Fig. 3, it can be seen that there can be any number of such Filtrir devices can be arranged next to each other, which together have a common steam jet fan, a common water inlet channel, pure water drainage channel and dirty water drainage channel and can be put into operation or cleaned independently of each other.

Claims (1)

Patent claim: An embodiment of the patent no. 58999 protected Filtrir device, in which straight Filtrir body (s) and blowpipes (n) arranged alternately parallel to each other in an open vessel (a) and for the filtrate discharge pipes ft) a rotatable collecting pipe (y) and two drainage channels (n > V ¹ J are provided, one of which only takes up the filtrate when cloudy filtrate has run through the other channel at the beginning of the filtration.
