Field of technology

BACKGROUND OF THE INVENTION The invention relates to an injection device for applying corrective agents, in particular to compositions for limiting the growth of cyanobacteria on water bodies, comprising a propulsion for propelling a vessel behind which at least one water nozzle and supply piping of the correction agent are arranged. water stream channel

The prior art

When contaminating water bodies with cyanobacteria, plankton, algae, oil, etc. there is a threat to aquatic animals and at the same time to the health of the users of water bodies, which is increasingly reflected in recreational areas.

Basically, two methods are used to eliminate the contamination of water bodies. One way is to powder water surfaces with correction agents from aircraft, the other way to powder correction agents from vessels.

Airborne dusting is disadvantageous due to the frequent dispersion of the correction agents beyond the water surfaces, which leads both to environmental hazards outside these areas and significantly increases the amount of correction agents required to effectively remove contaminants on the water surfaces and thus substantially increases the cost of the process.

Powdering of correction products from vessels is very time consuming, the whole process is unproductive and it is realistic to apply it only to smaller water bodies.

Therefore, a further method of introducing corrective agents into the affected water surfaces has been proposed, consisting in utilizing the propulsion tract of the vessel, where a correction agent is fed to the affected water stream in a channel with a propulsor, eg an axial pump. . The advantage of this method of introducing the correction jigs into the water is the possibility of relatively accurate introduction of the jig into the affected areas. By using the propulsion tract of the vessel the device is simple, easy to apply and the introduction of the correction jigs is low labor. low energy intensity.

• ·

These known devices are suitable for applying correction formulations in the form of solutions and fine granules to a certain flow rate of correction formulations, the increase of this flow rate being limited by the existing design of the injection device, especially when applying correction formulations with pulpy or lump coexistence.

It is an object of the present invention to design an injection device that allows the flow rate of correction devices to be increased, including slurry, possibly with lumpy coexistence.

SUMMARY OF THE INVENTION

The essence of the injection device for applying the correction jigs according to the invention is that the water nozzle opens into the mixing chamber of the injector, which is connected to the supply line of the correction jig. The mixing chamber and the water nozzle form a unit rotatably mounted on the channel of the propulsor, or the mixing chamber is provided at its outlet end with a pivotable injector nozzle.

Preferably, the injection device is provided with a control flap rotatably mounted on the water nozzle or at the outlet end of the injector.

Alternatively, a water intake inlet extends into the mixing chamber in addition to the supply line. The injection device can also be designed as multiple.

The advantage of this injection device for the application of the correction device is that it can be applied to various types of vessel power units, its ability to disperse the correction devices relatively accurately into the affected areas and to increase the flow rate of correction products, including slurries. . It is also possible for multiple devices to apply multiple correction devices simultaneously.

Overview of the drawings

FIG. 1 is a diagrammatic view of an injection device for applying correction devices according to the invention, wherein FIG. 1 is a longitudinal sectional view of a portion of the injection device; FIGS. 10 to 13 show a plan view of a further alternative embodiment of a part of the injection device in longitudinal section, and FIGS.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a channel 1 in which a propulsion 2 driven by a motor (not shown) for driving a vessel is arranged. The channel 1 terminates in a fixed water nozzle 3, which opens into a mixing chamber 4 in which the water coming through the channel 1 and the correction device coming through the inlet pipe 5 into the annulus formed by the jacket of the mixing chamber 4 and the jacket of the water nozzle 3 are mixed. At the end of the mixing chamber 4, a swiveling nozzle 7 is rotatably mounted about a vertical axis, on which a regulating flap 8 is swiveled about a horizontal axis. The swiveling nozzle 7 acts both for steering the vessel and for directing the emerging water mixture. correction agent into the surrounding water. The regulating flap 8 then acts as a reverser of the vessel's operation and also in the function of directing the outlet of the mixture of water and correction device in the vertical direction. The mixing chamber 4 is connected to the channel I by a sealing collar 9, which prevents water from entering the mixing chamber 4, except for the water coming through the channel L. The whole described device constitutes an injector which allows dosing of the correction agent in virtually any phase or structure, e.g. a liquid phase, a powder phase, a slurry, in the form of granules and the like.

In an alternative embodiment of the injection device of FIG. 2, the water nozzle 3 is rotatably mounted at the end of the channel 1 about a vertical axis. Here again, the water nozzle 3 is firmly connected by means of connecting ribs 6 to the mixing chamber 4, which at the same time fulfills the function of the swiveling nozzle 7 according to FIG. A regulating flap 8 is rotatably arranged about the horizontal axis on the mixing chamber 4.

In another alternative embodiment according to FIG. 3, the difference from the embodiment according to FIG. 2 is that the control flap 8 is rotatably mounted about the horizontal axis on the water nozzle 3 and lies entirely in the mixing chamber 4.

In another embodiment of the injection device according to FIG. 4, the mixing chamber 4 is connected to the supply line 5 for supplying the correction device.

In the embodiment of the injection device according to FIG. 5, the inlet pipe 5 can be seen opening into the mixing chamber 4, with the inlet 10 for sucking in additional water, at the same time, entering the mixing chamber 4, except for the water coming through the channel 1.
