in a steam boiler.

Patented in the German Empire on September 28, 1906.

The invention relates to a device for producing a linseed decoction and its introduction into a steam boiler to prevent scale formation. The invention consists in that a container is divided by sieve walls into several chambers, the first of which is the Includes linseed and a spray tube for feeding boiler water while the sieves

ίο for cleaning the pressed through it to the boiler Serve decoctions of solid ingredients.

The new device can with a simple design and good utilization of the introduced Flaxseed can be connected to any steam boiler.

The new device is shown in FIG. 1 in a longitudinal section, in FIG. 2 in a top view with the screen walls removed, and in FIG. 3 in a section along AA of FIG. Fig. 4 shows a single screen wall.

The device consists of a container, expediently made of sheet iron, which is divided into three compartments a, b and c by two sieve walls <f and e, which are pushed into tightly fitting guides in the side walls of the container and whose sieve surface is advantageously made of copper mesh . Of the sieve walls that are perpendicular to the side walls of the container, one sieve wall d, which closes off the chamber a that holds the linseed, is inclined towards the bottom in such a way that the seeds thrown from below against the sieve rise up on it and into the rear space of chamber a can fall back without attaching itself to the metal mesh. The lower corner m of the chamber a opposite the sieve d is expediently rounded so that the seeds cannot get stuck in it. The container is closed at the top by a lid /, g, Ii , the parts g and h of which can be swung open to allow easy removal of the sieve walls and the cleaning and refilling of the device.

At the bottom of the chamber α and in front of the sieve d there is a spray tube I through which boiler water is sprayed into chamber α , which is supplied through the connection pipe k , while the decoction through the chambers a, b and c and through the connection j in the boiler is pressed. The decoction can also be sucked off through the connection j and then pressed into the kettle. Flanges i (Fig. 2) on the container allow the lid to be sealed off.

The operation of the device is as follows. After the linseed has been introduced into chamber α and after the device has been closed, the boiler water is injected through tube I into chamber a , the seeds being thrown up against the sieve and up against it, and then falling back into the rear space of chamber a . The action of the water on the grains forms the decoction, which flows through the two other chambers b

and c is sucked off and pushed into the kettle. Here, the coarser sieve d holds back the larger solid components of the decoction, while the sieve also holds the fine ones carried away with it. Retains substances so that only pure solution gets into the boiler. The inclined position of the sieve d and the rounded corner m of the chamber α cause the flaxseed to circulate, which after

to fall back from the sieve through the spray tube / can easily be thrown against the sieve d again.

Claims (2)

Patent Claims: i. Apparatus for the production of linseed decoction and its introduction into a steam boiler to prevent scale formation, characterized by a container which is divided by sieve walls (d, e) \ x \ several chambers, the first of which is the linseed and a .spray tube (I. ) for feeding with boiler water, while the sieves (d, e) are used to remove solid components from the decoction that is pressed through them to the boiler. 2. Apparatus according to claim 1, characterized in that the first, the linseed-containing chamber from - '. Closing sieve (d) is inclined such that the linseed entrained by the radiant water introduced on this sieve is driven up to then to fall back into the chamber. 1 sheet of drawings.
