Slurry silo

The innovation concerns a slurry silo. Such mostly as high silos

trained silos are used on farms

i Use and serve for the temporary storage of animals in cattle stalls j

accruing liquid manure until it passes through the silo in due course

Pumping is removed and used to fertilize fields.

Especially with the manure resulting from the keeping of cattle

there is often the disadvantage that light dry substances,

Float up straw portions and the like in the silo and

Over time, form a solid, thick blanket that will appear on the manure level 3

swims. . f

To destroy and dissolve this floating cover, expensive I

Mixers used. These are in front of | in several places in the silo seen and have an essentially vertical, twisted ξ

adjustable tubular body with radially directed chopping tools sol ie Jf

Stirring nozzles through which slurry is pumped with a hard jet
among other things, on the floating cover to be dissolved.

It is true that the use of such agitators can result in destruction
reach the floating cover, but this often only after several days

R-drive of the agitators, as those that arose after the initial break-up Floating ceiling parts relatively seldom come into the range of action of the agitators. This leads to a correspondingly high Costs, especially if these devices or the pumps that feed them are driven via the PTO shaft of a constantly running tractor will.

The task of the innovation consists in eliminating those indicated Disadvantage. Accordingly, a slurry silo is to be proposed in which a floating cover that may have formed can be removed in the shortest possible time Can reduce time without having to use a large number of stirring tools * and the like.

To solve this problem, the slurry silo is designed according to the innovation so that .... (characteristic of protection claim 1). · *

As soon as the pump, for example, from a separate slurry pre-pit or pumps directly from a liquid manure canal in the cattle shed into the silo, the liquid level rises there and raises the

Floating cover on and finally over the level of the overflow to the secondary chamber. The floating cover is usually already partially broke open automatically. Independently of this, this process can still be supported by a few jet stirring tools and be accelerated. Pieces of the broken floating cover then float with the liquid manure over the overflow, falling into

the neo-chamber and are further crushed during the falling movement. A homogenization of the manure through finally complete dissolution this floating deck parts takes place when passing through the pump equipped with a ripper, which is in the circuit in the The silo space is conveyed back, so that liquid manure and possibly still existing manure are constantly available Drive parts of the floating ceiling over the overflow into the adjoining chamber and there they are pumped out again for the purpose of returning them to the silo.

Practical tests have shown that in this way the dissolution and the Abb-'u of the floating cover in a fraction of what has been done so far for this required time. In addition, the advantage is noticeable that comparatively fewer jet agitators and, as a result, less complex controls for these agitators must be used. The few necessary agitators only have the task, initially for an initial and to ensure that the floating cover dissolves in places. Then later the floating deck parts by themselves drive into the adjoining chamber, whereby they are further crushed when dropped and finally after being sucked into the pump.

The innovation is explained below with reference to the drawing, in the schematic embodiments are shown. Show it:

Figure 1 is a vertical axial section through a round silo with the arrangement according to the innovation /

Figure 2 is a plan view of the embodiment of Figure 1, FIG. 3 shows a silo in perspective with an outer secondary chamber according to the innovation.

The silo 1, made in a known manner from sheet metal, is mounted in a sealed manner on a corresponding base, the The silo itself can be round or square in plan. On the inside of the silo wall 1 (Figures 1 and 2) in the silo space 2 is a Secondary chamber 3 is formed by a weir wall 4, the upper edge 5 of which, as an overflow, is lower than the upper edge of the silo 1.

The silo space 2 is used to hold supplied liquid manure, above all of cattle, which contains solid light components, which swim upwards in the manure and here gradually a solid one Form a thick cover, which must be destroyed for the later removal of the manure or so crushed so that a homogenized one Liquid is created.

As soon as the liquid manure fed in from a stable or the like in the silo with the solid, thick and floating ceiling, the overflow

Edge 5 of the side room exceeds 3, the solid ceiling is through an agitator in the silo also swings over the overflow edge 5, the parts of the ceiling protruding over the overflow edge 5 break off due to their weight and together with liquid Slurry fall down into the side chamber 3, where the broken off Ceiling parts are further crushed by the fall.

In the lower part of this secondary chamber 3 is a slurry pump according to the innovation stored with an upstream ripper (not shown), through which the solid components of the ceiling are mixed with the manure and homogenized and then conveyed back into the silo by the pump, so that constantly parts of the solid ceiling get into the secondary chamber 3 together with slurry and are pumped back into the silo in a continuous cycle until finally the components of the solid ceiling are completely homogenized in the manure of the silo. This creates the possibility of the To empty the silo for the removal of the now completely liquid manure. By executing the slurry silo with the side chamber and the circulation pump, the dismantling of the solid thick ceiling is achieved in the shortest possible time.

Several agitators or jet agitators can also be installed in silo 1 be arranged, through which the solid ceiling is initially only broken, so that then the fragments by themselves over the Drive overflow 5 into the secondary chamber 3 and from there through the

Pump with a shredding mechanism, homogenized, can be pumped back into the silo. One or a few agitators are sufficient, which only need to be in operation for a relatively short time.

After the solid ceiling is completely floating in the manure of the silo j is done, the emptying of the silo can be done ^ that e.g. a slide valve 6 between the silo 2 and the secondary chamber 3 and e.g. another slide valve 7 of the secondary chamber 3 in the silo wall 1 is opened in order to transfer the liquid manure into transport tanks or the like to pump.

According to the innovation, it is also possible to mount the secondary chamber 3 according to FIG. 3 on the outside of the silo wall 1, but then reduce the height of the silo wall 1 in the area of the secondary chamber 3, around an overflow edge 5a for exaggerating the ceiling! to ensure fragments in the secondary chamber.

Finally, it should be noted that the overflow edge 5 or 5a is like a slide can also be adjustable in height in order to adapt to smaller or larger ^ 'üllhöhen the manure in the silo to reach. Next, it is also possible to use the circulation pump with shredding mechanism outside of the secondary chamber 3 in conjunction with the To arrange slide valve 7 and to keep this slide valve 7 open in the homogenizing operation to the pump for the recovery to be able to feed the liquid manure into the silo.
