PATENT OFFICE.

In briquette production, the material to be pressed is placed in a press above the press Out of the filling hull and from there it enters the press as required. The single The coal is pressed from a larger silo by means of a suitable one Feeding device supplied. So that the presses can always be operated evenly, it is necessary that also the content

ίο the press hulls kept fairly even will. In lignite briquette plants in particular, however, this regulation prepares some Difficulties and has so far been caused by special workers. To the exit To regulate the goods from the silo, sliders were attached to the exit point moved by hand or machine. But it comes z. B. more often that as a result Any operational irregularities no longer have enough coal to reach the last press hull is conveyed and this empties completely. In such a case, the machine must be shut down, which leads to a loss of performance means. But it is even more troublesome if, instead of too little, too much coal is conveyed into the press hull. is namely, the last hull is full, so the coals go to the transition screw and burden this often so strong that it stops.

The consequence of this can under certain circumstances be a complete shutdown of the company, which can last a few hours.

The manual control of the fuselage content is never carried out with the desired reliability, because you have no overview of the rise and fall of coal. Often enough, the operator notices them Overcrowding of the trunk only when it is already too late.

According to the invention, the control of the body content should now take place automatically. For this purpose, rotatable flaps are attached inside the fuselage, which are moved depending on the height of the content and when opening or closing one electrical contact. The different with the individual flaps, in connection standing circuits act on magnetic lifting devices to open and Close the outlet valve of the coal storage room. The lower the coal level in the Press body sinks, the more rotatable flaps close the associated contacts and act through the formed circuit on opening of the belonging to each flap Slide or a number of combined slide.

The invention should be explained in more detail with reference to the drawing, which shows an exemplary embodiment of the plant.

Fig. Ι is an overall view of the system,

Fig. 2 is a cross section through the coal storage space together with a view of the bucket elevator and the press hull.

3 and 4 show a special control flap in the two main positions with closed and open contacts.

α is the large coal storage room from which

chem the coal is fed to the upper mouth of the press body e by means of a screw b and a bucket elevator c and another screw d .

At the lower end of the funnel-shaped storage space α there are outlets f closed by slides g , in front of which feed rollers h rotate, which convey the coal evenly into the screw b .

ίο The more slides g are open, the more coal is fed to the press body. According to the invention, the number of each open slide g is now to be regulated as a function of the content of the press body.

For this purpose, a number of rotatable flaps i are mounted one above the other in the press hull e , the shafts of which are guided out of the hull to the outside, where they are in communication with the contacts k. The flaps i have roof-shaped inclined surfaces so that no coal can remain on them. The flaps are expediently mounted on the central axis of the fuselage.

So that the incoming material does not affect the flaps, a roof-like diverter m is attached under the feed opening. The flaps i are loaded by counterweights η , which are overweight and act when the contacts k are closed. If the flaps i are thus unloaded, ie unaffected by the coal, the contacts k are closed and the circuit formed keeps the associated slide g open. The more flaps i are unaffected, the more slides g are open and the more coal is fed from the storage space. If the material is fed to the press body too quickly, it soon fills up, and the flaps i covered under the coal material are carried along as a result of the movement of the material downwards. The more flaps there are under the surface of the coal, the more slides g are closed, thereby reducing the supply of coal.

The mechanical equipment of the system can of course be modified considerably, without changing the essence of the invention.

Claims (3)

. Patent claims: 1. From coal silo with movable slides in front of the outlet opening, feeding device and filling hull existing system for feeding briquette presses, characterized in that the falling material in the filling hull by means of When organs that have been dragged down, act on a number of electrical contacts, whose circuits determine the number of openable outlet slides of the coal silo depending on the height of the Regulating good in the press hull. 2. Apparatus according to claim 1, characterized in that in the press hull one above the other a number of rotatable, with their waves protruding from the hull Flaps are mounted, which open or close when they are rotated of contacts work. 3. Apparatus according to claim 2, characterized in that the rotatable Flaps have roof-shaped inclined surfaces to prevent the coal from resting on them. 1 sheet of drawings.
