Description

Technical area

1. (a) einen Behälter zum Erzeugen einer Lösung oder Suspension der Chemikalien; und
2. (b) eine schwimmende Einheit zum Ausbringen einer Lösung oder Suspension der Chemikalien auf das Gewässer.

The invention relates to an arrangement for introducing chemicals into water, in which a chemical-containing solution or suspension is distributed on or in the water containing

1. (a) a container for generating a solution or suspension of the chemicals; and
2. (b) a floating unit for applying a solution or suspension of the chemicals to the water.

The invention further relates to a mobile, transportable on a road vehicle container that can be set up on land, so that it can be filled ashore with a supplied chemical in the form of bulk or a liquid concentrate

Mining lakes are examples of waters where chemicals are added in the form of lime to increase the pH.

State of the art

WO 2004/067455 A1 discloses a device, such as a pontoon, truck, trailer, boat or ship, on which limestone is crushed and applied to the water. DE 34 13 702 A1 . US 5, 185.085 A and US 4,961,519 A reveal boats with lime, which is supplied to the water.

DE 20 2007 017 852 U1 describes a watercraft for introducing lime into water. The lime is stored on the watercraft as bulk material. Water from the water is sucked in with a suction device. In a metering device, a suspension is prepared from the dry lime and the drawn-in water, which is sprayed directly afterwards with a feed pump and distributor nozzles on the water surface.

DE 10 2004 032404 A1 discloses the treatment of large lakes with a water volume above 500 000 m ³ , where there is no adequately fortified bank area. The arrangement uses a floating, mobile storage / transport and entry unit, which generates a turbulent flow of water due to its speed.

DE 20 2004 002 159 U1 discloses a mobile and mobile storage and entry unit with a self-propelled or with an additional vessel, with the caustic soda can be introduced into water. The vessel is equipped with a tank container for intermediate storage of caustic soda. The watercraft is supplied from a mobile open safety trough and a container therein, can be cached in the solid or liquid neutralizing agent.

With the known arrangements, the pH of a body of water, in particular a Tagebaurestsees can be adjusted.

DE 10 2012 104 914 B4 discloses a watercraft in the form of a split folding barge in which the lime is used in the form of a concentrated solution or concentrated suspension on the watercraft. The use of a concentrated solution or concentrated suspension has the advantage that a significantly more chemical mass can be accommodated on the vessel than, for example, with bulk material. Bulk solids, in contrast to the same amount, have a larger volume in a solution or suspension. The watercraft can therefore absorb more chemicals and must be loaded less often. This increases the efficiency of the water treatment.

Another advantage of a concentrated solution or concentrated suspension is the better dosability. Homogeneous liquids can be dosed better than possibly inhomogeneous bulk material. This avoids over or underdosing and improves the quality of the water treatment. The chemicals are also longer in the liquid and are largely dissolved. This avoids that particles sink to the bottom of the water without dissolving. In this way, the dosage can be reduced, resulting in material savings. Also, the previously dissolved chemical reaches all deep layers of the water and thus causes a more even water treatment.

A disadvantage of known arrangements is that the entry unit requires a movement that is usually realized with a boat. However, boats can only sail on larger lakes and there must be a suitable bank area by which the boat is brought into the lake. It is also expensive to transport the boats after treatment from one lake to the next. Furthermore, the mixing of the suspension and the loading of the suspension tank on the boat requires several hours of time in which the boat can not be used to dispense the neutralizing agent.

It is an object of the invention to provide an arrangement of the type mentioned in which chemicals efficiently into smaller lakes can be introduced. According to the invention the object is achieved in that

• (c) the container is arranged to produce the solution or suspension of the chemicals ashore so that it can be filled ashore with the supplied chemical in the form of bulk or a liquid concentrate;
• (d) at least one water connection is provided for supplying sufficient water to the chemical in the container so that an application-ready solution or suspension can be produced;
• (e) hoses, pipes or other means are provided for transferring the ready solution or suspension to the floating unit; and
• (f) anchoring means are provided for anchoring the floating unit at a fixed position in the body of water.

The chemicals may in particular be lime or caustic soda. Unlike known arrangements, neither a ship nor a drive for the floating unit is required. The suspension or solution containing the chemical is already diluted ready for use on land. The thin suspension or solution can be easily transported via hoses or pipes to the floating unit. Further processing on the water is not intended. Eningly simple, the unit is formed. The arrangement is particularly easy to transport, bring into the water and install there. Especially for small lakes that need to be treated only discontinuously, for example, this simple and inexpensive solution is much more advantageous. Since the container for mixing and diluting the chemical is on land, the suspension or solution can be prepared and applied without interruption. There is therefore no downtime. In this way, the performance of the device is increased. In contrast to ship-based technology, the system can be operated around the clock and in any weather.

Preferably, an agitator or a circulation pump is provided in the container, with which the solution or suspension from the preparation to the application is stirrable. As a result, on the one hand solid material, such as lime, better resolved and on the other hand, any remaining solids may not settle.

The water connection of the arrangement is preferably fed from the water with water. Since the water flows back into the water together with the chemical, no imbalance arises here. The water does not have to meet any special requirements as it already had the quality of the treated water.

In one embodiment of the invention, a pump is provided, with which water from the water to the water connection of the container is pumpable. This is particularly useful if no flow or Tiedenhub are present and the container is arranged wholly or partially above the water surface. With the pump, a selected amount of water can be selectively pumped into the container, so that the concentration of the chemical in the water corresponds to a selected value.

In a particularly preferred embodiment of the invention, the pump has a pumping capacity of at least 100 m ³ / h, preferably of at least 120 m ³ / h and most preferably of at least 150 m ³ / h. A container, for example, receives a truck load lime in the form of bulk material is then sufficiently filled within about one hour.

The floating unit may in particular be formed by a pontoon without its own drive. It is advantageous if the pontoon is formed in several parts and the parts are individually transportable. This facilitates the construction and transport of the arrangement.

The anchoring means may comprise one or more anchors and / or weights attached to the floating unit by a rope. The anchor is anchored to the seabed and prevents lateral movement of the floating unit. Advantageously, four anchors are provided, which are mounted in pairs in opposite directions, approximately in a star shape over the corner, slightly spaced from the floating unit.

In a particularly preferred embodiment of the invention, the floating unit has a discharge unit, via which the ready-to-use solution or suspension is distributed in or on the water. The discharge unit may in particular be designed with discharge openings and is held between two sections of the floating unit in the water below the water surface. Then the solution or suspension with the chemical is discharged directly into the water so that it spreads evenly on the principle of the free jet. A lowered discharge unit prevents the chemical from remaining on the surface and allows deeper flows to distribute the solution or suspension in the water.

The arrangement is a mobile, transportable, self-contained unit. This is self-sufficient functioning, ie equipped with control and regulating organs, so that it is independently functional.

• (c) wenigstens ein Wasseranschluss zum Zuführen von ausreichend Wasser zu der Chemikalie in den Behälter vorgesehen ist, so dass eine anwendungsbereite Lösung oder Suspension erzeugbar ist;
• (d) wenigstens eine Pumpe und/oder ein Rührwerk zum Erzeugen einer Lösung oder Suspension der Chemikalien vorgesehen ist;
• (e) Schläuche, Rohre oder andere Mittel zum Überführen der anwendungsbereiten Lösung oder Suspension zu einer schwimmenden Einheit vorgesehen sind; und
• (f) der Behälter Steuer- und Regeleinheiten aufweist, so dass der Behälter autark arbeitet.

The object is further achieved with a container which is characterized in that mobile transportable on a road vehicle container that can be set up on land,

• (C) at least one water connection is provided for supplying sufficient water to the chemical in the container, so that an application-ready solution or suspension can be generated;
• (d) at least one pump and / or agitator is provided for generating a solution or suspension of the chemicals;
• (e) hoses, pipes or other means are provided for transferring the ready-to-use solution or suspension to a floating unit; and
• (F) the container has control and regulating units, so that the container operates independently.

The container is in particular a commercial container that can be transported on a conventional low loader on conventional roads. The plant is thus in particular no fixed installation. The container has in particular dimensions with a length of 5 to 20 m, a width of 1 to 4 m and a height of 1 to 4 m.

With the arrangement, a need-based dilution of the prepared suspension or solution between 0% and 100% is possible. It is also the needs-based dosage of the suspension possible. The water-based discharge unit for discharging the suspension solution can preferably be effected below the water surface. It is preferably a fixation of the discharge unit to a float.

Embodiments of the invention are the subject of the dependent claims. Embodiments are explained below with reference to the accompanying drawings.

Description of the embodiments

1 to 6 show a generally designated 10 container. The container is placed in the bank area of a body of water. The waters require treatment with chemicals. Such treatment with lime is useful, for example, in acidified waters such as opencast mines. The container 10 is essentially cuboid and made of steel. The container of the present embodiment has a length between 7 and 9 meters, here 8 meters and a width between 2 and 3 meters, here 2.62 m. With these dimensions, the container can be transported at a time with a low-loader truck on conventional roads. At the same time the container has a volume which allows a high efficiency.

On the sides is the container with ribs 12 strengthened. Alternatively, the container can also be made with a larger wall thickness. The container 10 is with a cover 14 and manholes 11 Mistake. The cover 14 is formed in two parts. This allows the cover over the entire length along the connecting line 16 be unfolded. These are handle strips 19 intended. In the unfolded state, the opening allows bulk material, for example lime, to be transferred directly from a truck into the container. Side ladders 18 provide access to the cover, for example for opening or inspection purposes.

The cover 14 of the present embodiment has four inspection holes or manholes with a separate flap 11 are closed. The flaps 11 can each handle 20 be lifted and folded. Then the container interior is accessible from the outside.

The container 10 has two connections 22 and 24 , To the connection 22 Hoses (not shown) are connected. Through the hoses water is pumped out of the water to be treated. For this purpose, a pump (not shown) provided, which has at least 100 m ^{3 of} water per hour, here 150 m ³ / h pump power.

That way, the container can 10 be filled with the amount of water that is required for the preparation of a ready solution or suspension. The concentration required for the application depends, among other things, on the type of chemical and the desired and actual value for the pH of the water to be treated.

The water connections 22 and 24 are on the right in 1 , The water connection 22 then leads directly into an underneath chamber 26 that in average in 5 can be seen. The interior of the container 10 is with a partition 30 in two chambers 26 and 28 divided. A passage 32 connects the chambers 26 and 28 in the ground area. The connection 24 is with a pipe 34 connected. The pipe 34 leads to the in 5 left chamber 28 So on the connections 22 and 24 distant side of the container. About the outlet 24 For example, the suspension or solution produced in the container may be passed to a pontoon described below. Also for this purpose a pump and one or more hoses is provided (not shown). One of the ends is submerged in the suspension or solution within the container through the outlet. The other end is led to the pontoon. Instead of going to a pontoon, the solution or suspension can also be pumped onto a ship.

In the bottom area of the chambers 26 and 28 is in each case a stirrer 36 respectively. 38 arranged. These are also in 5 to recognize. With the stirrers 36 and 38 the solution or suspension is circulated in the chambers. In this way it is avoided that solids settle to the bottom. In addition, the homogeneity of the solution or suspension is produced and maintained. Instead of a stirrer or in addition, a circulating pump (not shown) may be provided.

At the water connections 22 and 24 opposite end of the container 10 are two air outlets 40 and 42 in the cover 14 intended. 7 and 8th show schematically a floating on the water pontoon 44 , The pontoon 44 is designed in several parts. Each 4 Ponto blocks 46 are by means of connectors 48 summarized. There is a gap between the two groups 50 , On the pontoon is a steel profile 52 applied, which also serves as a connector. On the steel profile 52 is a suspension 54 attached. The suspension 54 carries a lance-shaped discharge unit 56 ,

Each at the corners 58 of the pontoon 44 are ropes 60 attached. The ropes 60 extend in a star shape outward in the direction of Seeboden 64 , There they are with an anchorage 62 anchored.

The arrangement works as follows: Lime in the form of bulk material is transported by truck directly to the open container 10 driven and through the open cover 14 dumped in the container. After closing the cover, water is released from the water into both chambers of the container 10 pumped. The stirrers and / or the circulation pump roll over the suspension or solution, whereby the bulk material can be well dissolved and distributed in the water. The suspension or solution becomes the pontoon via one or more hoses 44 directed. This is done by means of a circulating and discharge pump within the container. When the solution or suspension is pumped to the pontoon, the discharge pump has a low pumping capacity of about 2 square meters per hour. When the solution or suspension according to an alternative embodiment is pumped to a ship with its own tank, the pump has a high pumping capacity of 100 m2 / h.

At the pontoon, the hose with a metering pump to the application unit 56 connected. The spreading unit 56 is provided with openings through which the suspension or solution enters the water. The ever-present currents in the waters ensure a slow and even distribution of the suspension or solution. Since the suspension or solution has already been completely diluted on land, further equipment in the area of the pontoon is not required. The pontoon 44 can easily be landed, disassembled and transported to the next site after completion of the action. For the pumps and the agitator control and regulating organs are provided.
