PL407303A1 - Method for introducing fluid preparations, utilized in fish farming, fish culture, water control or reclamation of lakes in its near-bed level or inside the water reservoir settlings - Google Patents

Abstract

The subject of the invention is a method of distributing liquid preparations in the bottom layer of water reservoirs or introducing these preparations into bottom sediments. This applies to substances such as pesticides, fish medicines, probiotics and other substances used in fish farming, fishing, water protection or lake reclamation. The solution to this problem is the use of environments with the same parameters - water - water solution. Motopumps with a combustion engine allow for penetration into the sediment and for the application (pumping) of the given liquid with simultaneous water exchange (well-oxygenated surface water to bottom, poorly oxygenated waters). The motor pump draws water from the surface of the tank and forces it into the bottom layer. The introduced solution is applied by letting a motor pump into the suction or forcing pipe. Such a solution will cause the flowing stream of water to lift the introduced liquid and lead the mixture to the bottom of the reservoir (lake). The injection of the solution into the bottom layer will take place through a pipe sealed at both ends and fixed perpendicularly to the pressure pipe. Throughout its length, there are holes or nozzles for precise distribution of the mixture. The pressure pipe of the motor pump is placed exactly in the center of the pipe with holes. The length of the cross tube depends on the motor power of the motor pump, the depth and shape of the bottom of the tank. The pipe for introducing the mixture is tipped with a sharp and solid tip. Above the tip, there are holes or nozzles that enable the mixture of solutions to be forced into the sediment. Additionally, a sleeve is placed, which slides down when the blade is removed from the sediment and closes the outflow holes.
