DE2427041A1 - Pneumo-static stabilising technique for transportation of bulk liquids - using gas filled pressurised bladder over free surface - Google Patents

Abstract

The pneumo-static stabilising technique for bulk goods such as liquids with freely movable surfaces in closed transport containes. The technique includes the attachment of a variable shape pressurised bladder which is inflated up to a pre-determined stereotyped pressure which is calculated in accordance with a formula based on the hydrostatic weight divided by the viscosity of the material being transported. This pressure is exerted as a pressure bolster on the surface of the liquid being conveyed and is kept constant by the operation of the pneumo-static installation supplying gas to the bladder interior. Typically the gas used in the bladder can be air, nitrogen, or carbon dioxide etc. The bladder itself may be made of reinforced rubber or a plastics based elastomer and which does not react chemically or physically with the liquid being transported.

Description

Pneumostatic stabilization technology for transported goods.

The invention relates to a pneumostatic stabilization technique for a transport good with a freely movable surface, in a closed transport container, in particular for transport liquids in the transport traffic of shipping, railways, Aviation and road traffic.

A stabilization technique is used in transport traffic with such cargo necessary, on the one hand, because of the low dimensional stability and light weight Displaceability, no mass displacement due to the filling quantities in the transport container and / or changes in shape are possible, so that the transporter with changing Driving conditions a safe lateral and longitudinal stability is always given. On the other hand should be during driving, through a safe balance determination and establishment the filling quantities, swaying and / or skidding as well as coupling and / or pitching vibrations be dampened. It must be ensured that when driving for this type of filling quantities a statically stable transport option is given so that the necessary typical The transporter's driving characteristics are retained.

At the same time, there must be no danger to the transporter or the environment due to unstable transport storage and transportation of such goods possible graze.

It is known that to meet these requirements large-scale Transport containers are divided in which you can by leveling transverse and / or Long walls made of chambers. There are also chamber systems with open overflow openings and / or trim tabs known. These types of transport containers still exist No statically stable storage option and transport option of the aforementioned Transport goods.

The invention is based on the object for a transport of Transport goods with freely moving surfaces a stabilization method and - to create technology with a high level of security and to make it ready for use.

This object is achieved according to the invention in that the pneumostatic Stabilization technology in the transport container of any kind a shaping, stretchable Introduces pressure bladder (attached).

Via a pneumostatic Alage, which is known from operational safety Elements is appropriately equipped, a working medium is in the pressure bladder pressed until a specified stereotype pressure value is in the pressure bubble, so dats the stereotype print in the form of a pressure pad on the freely movable surface burdens.

In order to be able to create such a typical pressure cushion, the j the respective transport goods via a specially created nomogram table of the necessary To determine stereotype pressure value. This stereotype pressure value is used as the control value Control system of the pneumostatic system specified (supplied) so that the typical Arbeitsberricht can take place. If a transporter is filled and / or partially the empty space is also emptied, enlarged or reduced accordingly, with it the stereotype print in the pressure bubble also changes. The work performed by the pneumostatic system is also made Garin that the predetermined stereotype pressure value in the pressure bladder is to be automatically kept constant under all circumstances According to a further embodiment of the invention, the stereotype print value is by-ch characteristic Eormel determined by the hydrostatic gravitational pressure of a Goods to be transported divided by their toughness (viscosity) as an expression comes.

bin Exemplary embodiment of the invention is shown in the drawing and described.

To get a numerical result for a stereotype print, are from figure. 1 der beichnur, the functional relationships can be seen. One Appropriate nomogram tables will be created if there is enough experience ascertain / exist.

In Figure 2, Figure 2a, the shape-forming stretchable bridge bladder hangs schematically informally in the transport container, Figure 2b shows a schematic of a pressure pad for a given Filling amount is shown.

Scheme of a pneumostatic system can be seen in FIG.

The advantages achieved with the invention are in particular: that the known storage and transport difficulties are not given me, even under extreme driving conditions.

When driving, the mass and axial shifts of the center of gravity are absolute locked out. Evaporation phenomena in the transport container, depending on the location of things that can lead to fires and / or explosions are also excluded. Aggressive transport goods such as highly flammable operating materials, acids, alkalis and the like are safer to transport. These goods cannot run out more when a van overturns in road traffic due to circumstances is. Explosives and / or pests that are aggressive even with slight vibrations are particularly difficult to transport; they can be broken down by the aforementioned Stabilization technology easier and safe to transport, an advanced one It is used to stabilize the quantities of operating fluids carried in shipping and / or aviation. In the supply of consumables and ammunition of the army, air force and navy are stabilization and positioning problems known, which can be easily avoided by using the aforementioned stabilization technique is applied. There can also be cargo shifts in air transport and ship transport traffic can thus be prevented.

Every modern Dr-ansporter has a central compressor system that The entire company is supplied with compressed air via a pipeline network, which is a simple construction allows. Stability accidents occurring annually all over the world of vans show that a high percentage of total losses are due to dynamic Stresses have been caused. These stabilization accidents are not menr justifiable.
