DE3020214A1 - Tall wooden agricultural silo vegetable juice drainage - involves full height vertical perforated run-off ducts on walling inside - Google Patents

Abstract

Drainage extending over the full height is provided for tall silos made of wood, esp. as used for storing vegetable fodder. Fermenting juice is conducted to the silo floor slab by a series of upright runoff ducts on the inside of the walling (12), incorporating holes or slots. The runoff ducts are pref. located on both sides of entry hatches, and/or distributed round the silo periphery. A horizontal, similarly perforated duct, on the floor slab along the inside wall, can convey juice onwards to the outflow shaft in the floor. Upright ones may have tubes of various shapes, or grooves let into the walling. This provides effective runoff facilities over the whole height, and automatically reduces internal pressure arising from juices, while preventing any uncontrolled escape harmful to the environment.

Description

Drainage device for wooden silos.

The invention relates to a drainage device for wooden silos, as they are used especially in agriculture as green forage silos.

The purpose of the invention is to cover the entire height of the wooden tower as well at its base plate a good drainage facility for the resulting fermentation juice received, thus the internal pressure of the high silo created by the fermentation juice automatically reduce the fermentation juice in the generally intended, avoiding air supply To direct drainage channels and thus-uncontrolled, environmentally harmful running away de to prevent fermentation juices.

It is known that the bottom plate of such silos with one or more to provide siphon-like juice drainage shafts.

In practice, however, it turns out every year that sometimes for weeks Streams of fermentation juice from all cracks and joints, especially on the sealing surfaces the entry gaps and the installation surface on the base plate reach the outside, especially if in the lower part of the silo relatively impermeable to juice and above very juicy fruits are stored.

The construction of the silo was different in these cases occurring internal pressure has not grown, so that this is bursting, namely in the ones The height at which the greatest quantities of fermentation juice had accumulated.

Drainage device for wooden silos.

The proposal has already been made to have such silos with juice drainage channels, which are connected to the interior via valves, & equip or to design the clamping rings of the silo as a pipeline (German patent specification 885 170).

However, such constructions appear in practice from i.a. Impracticable for reasons of cost and are likely to be perfect in the longer term become ineffective because z. B.

the clamping rings of the wooden high silo are tightened annually have to and thus constantly change their position.

The suggestion has already been made, the silo juice from the silo suction from the base plate (German Patent 1 178 634) and from different heights of the silo (German patent specification 1 185 852).

This time-consuming method does not apply to a silo with, for example, white 12 meters from the start.

Also known is the proposal, the silo with a tubular inside Pillar to be provided (German Patent 1 092 719) what an obstacle first Ranges inside the silo and the use of mechanical silage removal devices makes impossible of any kind.

The invention lit the object based on wooden high silos with a simple, effective and automatic drainage system, which is provided for both new buildings as well as with old buildings without great costs and above all without structural Drainage device for wooden high silos.

Changes to the silo can be built in and thereby the use mechanical silage removal devices do not affect me.

According to the invention, this object is achieved by the fact that several The inside of the silo wall is installed vertically, reaching to the base plate and juice drainage channels provided with small holes or slits, advantageously white on both sides of the access hatches and / or. or - distributed over the circumference of the silo, direct the fermentation juice to the silo base plate and pour it along the Inside of the silo wall as well as to the juice blue shaft in the silo floor slab, Juice blue channel, also provided with small holes or slits, flows through the water forwards to the well-known siphon-like juice drainage shaft in the silo bottom plate.

The vertical juice drainage channels can be in the shape of a round or angular tube, a round or angular U-profile or a round or angular Cap profiles, but can also be loaded into the silo wall, as round or be executed angular groove, which with a planar or rounded or arched angular, -mit small holes or slots equipped cover is provided.

Further possible embodiments of the invention are that with execution with execution of the vertical juice drainage channels as round or angular U-profiles as well as round or square hat profiles, or in execution as a groove embedded in the silo wall, whose flat or rounded or angular bulged Side cover with pointed and advantageously white ram hook-shaped Fastening claws are provided, which both assemble into the wood of the silo wall being pushed or hit.

Another implementation option is the transition from the vertical juice drainage channels to the horizontal juice drainage channel with an apron-like one Cover to be provided in order to easily prevent the fermentation juice from jamming here avoid.

The advantages that can be achieved with the invention are in particular the following: Zs is possible without structural changes in and on the silo, the vertical as well as to install the horizontal juice drainage channels.

With new buildings it is not a problem at all in some of the silo planks, Which yes, as is well known, a wooden high silo consists of milling round or square grooves, but this is also the case with old buildings. B. possible with the help of a hand milling machine. Drainage device for wooden high silos.

These grooves do not affect the stability of the silo wall Impaired, because yes the covers attached to it at the same time as a stability compensation works.

When these covers are designed with side hook-shaped hooks Fastening claws ensure easy and quick assembly of the same and avoided from the outset that fastening parts, such as screws, Nails, tabs or brackets can come loose and get into the forage, whatever also applies if the vertical juice drainage channels are round or square U or Hat profiles' are designed with lateral ram hook-shaped fastening claws.

The horizontal juice drainage channel does not need to be attached at all to become and therefore does not even interfere with cleaning work.

The different embodiments of the vertical juice drainage channels or / or. the covers can be made of acid-proof steel, with acid-proof Plastic-coated steel, but also made of acid-resistant plastic as well galvanized steel can be produced without great difficulty.

For the sake of simplicity, the horizontal juice drainage channel is e.g. made of PVC drainage pipe uEd can therefore be easily accessed to the juice drainage shaft in the silo base plate. be laid, whether in or on "the floor slab.

Drainage device for wooden silos.

It has been shown in practice that when equipping the juice drainage channels there is no risk of clogging with small holes or slits, only the vertical juice drainage channels should be closed at their upper end, e.g. to avoid corn kernels falling in.

Furthermore, practice shows that vertical juice drainage channels in size a half-inch gas pipe is sufficient and thus the use of mechanical silage removal devices do not hinder, yes, when designed as a single-milled groove with a planer in the silo wall Cover doesn't even stand out.

Since the juice drainage channels according to the invention only with the siphon-like Juice drainage duct in the Sibo base plate could be connected in practice no false fermentations caused by the invention are found.
