Description

Technical field of the invention

The present invention relates to a safe transport of and handling of hazardous liquids. More particularly, the invention relates to a Composite Intermediate Bulk Container for the safe transport of and handling of both a liquid acid and a liquid acid with dissolved nutrients.

Background of the invention

Seeds need nutrients to help them grow properly. Above all, compounds such as nitrogen, phosphorus and potassium are important to promote efficient yield. However, micronutrients such as manganese, boron, magnesium, zinc, copper and selenium are also needed. In order to provide the crops with sufficient nutrients, nutrients from the fertilizer or fertilizer, for example, by spreading manure, are added to the seeds separately. However, the plant fibers in the slurry do not represent an optimal fertilizer product because the nutrients are organically bound therein and the slurry does not contain the proper nutritional formula.

A new method for improving the ability to use manure fibers and the lack of a correct formulation is by means of the in the patent application EP2272316 and EP2514294 SyreN system described in detail. The SyreN system uses sulfuric acid to release the nutrients from the plant fibers in the manure.

In order for the farmer to handle this process and safely disperse the liquid acid with dissolved nutrients, the farmer needs a means of transporting and handling both the liquid acid and the liquid acid with dissolved nutrients.

Detailed description of the invention

An object of the present invention is to provide a means for transporting and handling both the liquid acid and the liquid acid with dissolved nutrients.

The above-mentioned object is achieved by a composite IBC according to the present invention.

Intermediate bulk containers (IBCs) are large industrial containers having a capacity of approximately 450 and 3,000 liters, as defined in the Department of Transportation Hazardous Materials Regulations, and used for the transport and storage of fluid bodies. IBCs can be made of high performance plastics such as high density, high molecular weight polyethylene and can be made into numerous shapes, including stackable cubes. A particular type of IBC, the composite IBC, may include in its design a metal cage, usually made of steel, surrounding the plastic container To ensure support and protection, and to facilitate the stacking of the composite IBC. Composite IBCs typically include a pallet for added strength and to facilitate transporting the composite IBC by means of a forklift truck. Composite IBCs typically have a fill port (inlet) positioned at the top for filling and mixing liquids and a drain valve (or spout) at or near the bottom to facilitate dispensing of the contents. The inner plastic / polymer vessel (the bottle) can be replaced if necessary during repair and reuse of the IBC.

Despite the efforts to strengthen the composite IBC to facilitate transportation, there is still a need for a composite IBC meeting the conditions set out in the European Convention on the International Carriage of Dangerous Goods by Road, commonly known as ADR listed. Such a composite IBC can then be used for the international transport of hazardous substances such as a liquid acid and a liquid acid with dissolved nutrients in wheeled vehicles. Although some composite IBCs can meet these conditions, there is still a need for further improvement.

A specific object of the present invention is to provide a composite IBC in which the risk of leakage is reduced.

The above object is achieved by placing an impact protection, e.g. B. in the form of a metal or polymer plate, dissolved over the fork guide in the forklift pallet base. If the user of the forklift misses the fork guide, he will collide with the composite IBC just above the forklift pallet base, thereby causing the danger of the vessel being penetrated, resulting in leakage. Placing the impact guard over the fork guide reduces the risk of leakage when impacting.

One aspect of the present invention relates to a Composite Intermediate Bulk Container (IBC) for a liquid acid or a liquid acid with dissolved nutrients, comprising an upper section (FIG. 30 ), a bottom section ( 31 ), a front section ( 32 ), a rear section ( 33 ) and two lateral sections ( 34 ), wherein the composite IBC is a vessel made of a suitable polymer and acid resistant material ( 1 ), a forklift pallet base ( 2 ), which a fork guide ( 21 ) and designed to intercept any leakage therein, a metal frame ( 3 ) based on the forklift pallet base ( 2 ) for stabilizing the vessel ( 1 ), an inlet ( 4 ) into the vessel for filling with a liquid acid or a liquid acid with dissolved nutrients and an outlet ( 5 ) from the vessel for removing a liquid acid or a liquid acid with dissolved nutrients, characterized in that the composite IBC also has an impact protection ( 6 ), which over the fork guide ( 21 ) in the forklift pallet base ( 2 ) to increase the overall impact strength of the composite IBC.

In one embodiment, the impact protection is in the form of a metal or polymer plate.

In another embodiment, the impact protection on the forklift pallet base is ( 2 ) and / or on the metal frame ( 3 ) assembled.

In yet another embodiment, the impact protection on the vessel ( 1 ) assembled.

Another specific object of the present invention is to provide a composite IBC that is safe to use during loading and unloading of a liquid acid or a liquid acid with dissolved nutrients.

The above task is accomplished by placing the spout ( 5 ) in the upper section ( 30 ) of the composite IBC, and wherein the spout ( 5 ) a coupling system ( 12 ) for the safe coupling and decoupling of a suction channel. The coupling system ( 12 ) is with a channel ( 13 ) connected by the coupling system ( 12 ) to the bottom of the vessel ( 1 ) extends. The spout is normally placed in or near the bottom section to facilitate dispensing of the contents. However, this location increases the risk of collision with the forklift, and if the spout is dysfunctional, the fluid content will leak due to gravitational force. This is avoided by placing the spout in the upper section.

Another aspect of the present invention relates to a composite intermediate bulk container (IBC) for a liquid acid or a liquid acid with dissolved nutrients, comprising an upper portion (FIG. 30 ), a bottom section ( 31 ), a front section ( 32 ), a rear section ( 33 ) and two lateral sections ( 34 ), wherein the composite IBC is a vessel made of a suitable polymer and acid resistant material ( 1 ), a forklift pallet base ( 2 ), which a fork guide ( 21 ) and designed to intercept any leakage therein, a metal frame ( 3 ) based on the forklift pallet base ( 2 ) for stabilizing the vessel ( 1 ), an inlet ( 4 ) into the vessel for filling with a liquid acid or a liquid acid with dissolved nutrients and an outlet ( 5 ) from the Vessel for removing a liquid acid or a liquid acid with dissolved nutrients, characterized in that the spout ( 5 ) in the upper section ( 30 ) of the composite IBC, and wherein the spout ( 5 ) a coupling system ( 12 ) for the secure coupling and uncoupling of a suction channel, and wherein the coupling system ( 12 ) with a channel ( 13 ) connected to the coupling system ( 12 ) to the bottom of the vessel ( 1 ) extends.

In one embodiment, the coupling system ( 12 ) a clutch shoe for the safe coupling and decoupling of a suction channel.

In another embodiment, the enema comprises ( 4 ) a coupling system for the safe coupling and decoupling of a filling channel. Such a clutch system may comprise a clutch shoe in yet another embodiment.

In another embodiment, the vessel is ( 1 ) to form a sump below the tube ( 13 ) for easier emptying of composite IBC.

Yet another aspect of the present invention relates to a Composite Intermediate Bulk Container (IBC) for a liquid acid or a liquid acid with dissolved nutrients comprising an upper portion (FIG. 30 ), a bottom section ( 31 ), a front section ( 32 ), a rear section ( 33 ) and two lateral sections ( 34 ), wherein the composite IBC is a vessel made of a suitable polymer and acid resistant material ( 1 ), a forklift pallet base ( 2 ), which a fork guide ( 21 ) and designed to intercept any leakage therein, a metal frame ( 3 ) based on the forklift pallet base ( 2 ) for stabilizing the vessel ( 1 ), an inlet ( 4 ) into the vessel for filling with a liquid acid or a liquid acid with dissolved nutrients and an outlet ( 5 ) from the vessel for removing a liquid acid or a liquid acid with dissolved nutrients, characterized in that the outlet ( 5 ) in the upper section ( 30 ) of the composite IBC, and wherein the spout ( 5 ) a coupling system ( 12 ) for the secure coupling and uncoupling of a suction channel, and wherein the coupling system ( 12 ) with a channel ( 13 ) connected to the coupling system ( 12 ) to the bottom of the vessel ( 1 ), the composite IBC also having impact protection ( 6 ), which over the fork guide ( 21 ) in the forklift pallet base ( 2 ) to increase the overall impact strength of the composite IBC.

In one embodiment, the suction channel is a suction tube or suction hose.

In another embodiment, the composite IBC also includes an outer wall ( 8th ), which along the entire circumference of the vessel ( 1 ) and at the forklift pallet base ( 2 ) in order to increase the overall impact resistance of the composite IBC and to reduce the risk of the user coming into contact with an escape from a torn vessel.

Many composite IBCs are designed to be stacked. This is actually very uncomfortable in terms of safety, as it increases the risk of accidents - especially when the composite IBCs are filled with hazardous liquids, such as a liquid acid.

In one embodiment, the composite IBC also includes an upper cover (FIG. 9 ), which are placed above the outer wall ( 8th ), the shape of the upper cover ( 9 ) and the bottom section ( 31 ) is performed in such a way as to prevent the stacking of individual composite IBCs.

The liquid acid with dissolved nutrients may comprise insoluble residues from the fiber material.

In another embodiment, the composite IBC also comprises a circulation system ( 11 ) to prevent the liquid acid from settling on dissolved nutrients or settling down.

It may be advantageous that the circulation system is detachable to replace an old vessel with a new one, without also having to replace the circulation system.

In yet another embodiment, the composite IBC further comprises a releasable circulation system ( 11 ) to prevent the liquid acid from settling or settling with dissolved nutrients, the soluble circulation system (US Pat. 11 ) when operating with the inlet ( 4 ) connected is.

When using the liquid acid and the liquid acid with dissolved nutrients as additives for a slurry fertilizer, the feed / suction pump may inadvertently suck in air instead of the additives. This will lead to an error in the calculation of the applied nutrients for the soil. For this reason, it is important to have a system that can be used to control the actual added volume of additives (ie, liquid acid and liquid dissolved nutrient acid) from the composite IBC. By incorporating such an optical indicator ( 14 ) of the volume fraction in the front During the fertilization process, the composite IBC section can see it from the operator of a slurry truck and continuously check that the system delivers the necessary amount of fertilizer to the soil.

To continue the risk of impact between the vessel ( 1 ) and to reduce the fork of the fork-lift truck in operation, the height dimension of the fork guide can be increased compared to the height dimension of the fork guide of a EURO pallet.

In another embodiment, the fork guide has a height dimension of at least 10 cm, such as in the range of 11-30 cm, z. B. at least 12 cm, such as in the range of 13-25 cm, z. B. at least 15 cm, such as in the range of 15-25 cm, z. B. at least 20 cm, such as in the range of 20-30 cm, to the risk of an impact between the vessel ( 1 ) and the fork of the operating forklift truck.
