Flour separator.

Patented in the German Empire on March 7, 1880.

The invention relates mainly to a bag apparatus which has an inclined Contains bag surface and an elevator (scoop device).

j The scoop is what is to be bagged Flour brought to the upper part of the inclined surface of the bag and must be repeated several times pass the surface of the pouch. This shakes the flour very quickly.

In addition, the invention relates to various details, of which below the Speech will be.

In the drawing is:

Fig. Ι view of the new bag machine (part of the front wall is broken away),

Fig. 2 cross section,

Fig. 3 basic riffs (with the cover removed), Fig. 4 end view.

A is the box of the machine, which rests on the feet B , C is the inclined sieve made of bag cloth and D is the scoop wheel. The inclined sieve consists of one or more frames which are covered with bag cloth, the frame rests on the ledges e on each side wall of the box, so that the sieve C can easily be removed if necessary.

As can be seen, the bucket wheel consists of a certain number of long blades f of quarter-circular cross-section, which are connected to the shaft g of the wheel by the spokes h , i is the trough-shaped bottom of the box A; the same is designed such, that the blades / almost touching it, they That the take on the floor i lying flour. The inclined sieve forms the end of the floor towards the front. When the flour falls out of the shovels /, it falls against the front wall of the box above the sieve C and from there onto the sieve.

J represents a conveyor in the usual shape of a screw. It is located under the sieve, collects the flour and semolina that has fallen through the mesh of the sieve and guides it to the emptying openings JJ ¹ J ² -

kk are hammers that shake sieve C by knocking on the top bar of the frame of C ; These hammers are attached to the shaft / which rests on the bearings I ¹ l ^l and is moved by thumb or pin m at the end of the conveyor shaft J. The latter is driven by means of a crossed belt η from the pulley N on the shaft g or by similar transmissions. The screen frame is expediently provided at its lower edge n ¹ with a strip of rubber or some other elastic material. This acts as a buffer and supports the shaking movement of the sieve by returning the tugs of the hammers k .

The box A has an opening at the front, which is closed with the board P. If you take away this board P , you can see the state of the sieve and possibly clean the underside of the same with a brush.

Both the scoop wheel D and the sieve C are slightly inclined lengthways, as is also the case with the simple bag apparatus; -the purpose is the same as there.

The flour to be bagged is thrown into the machine through q and falls either directly into the shovels / "or onto the bottom i, from where it is lifted up by the shovels and thrown onto the top of the sieve c , then it rolls over the surface same.

As a result of the inclined ^f position of the cylinder D and sieve C , the material moves lengthways from g towards r at the same time. The sieve C is provided with bags of different mesh sizes.

Assuming that the finest meshes are on the uppermost part of C (next to N), the finest flour will fall through at this point. The last field of Cs is wide-meshed, so that the semolina falls through here, the bran goes off through r .

The trough / the auger J is provided with individual closures so that any quantity of bagged flour can be returned to the box A again. Furthermore, the individual sections of the sieve C can be separated, so that some of them can be removed and replaced by others of a different mesh size. can. When removing the sieve, both sides of the bag cloth can be cleaned, whereas with the cylinders that are now in use, you can only clean the outside. Furthermore, the bagged flour cannot be contaminated again by flying bran, because the spaces for the bagged and unbagged flour are completely separated by the sieve.

The above-described apparatus has the advantage that the flour to be bagged is always brought onto the sieve in small quantities because of the small scoops f. In this way a continuous, thin stream of flour flows over the sieve, so that this is continuously evenly stressed and the bagging is therefore very rapid.

The flour grains always run in the same direction over the sieve, so that grains of of the same size must fall through a certain part of the sieve.

The bucket wheel acts at the same time as a fan, it cools the flour and prevents it from happening lumps appear on the sieve.

The blades f can be fastened on a completely closed drum or on troughs or belts running over rollers without end.

PATENT claims: 1. In a bag apparatus, the connection of a scooping device with an inclined one Sieve, which is in front of the former and made up of different ones standing next to each other Is composed of divisions of decreasing fineness of the mesh, so that this Flour is separated in quantities of different fineness. 2. The device for shaking the sieve, consisting of the elastic pad n ¹ and the hammers K. 3.
