SU1250231A2 - Arrangement for aeration of water in container with alive fish - Google Patents

Description

The invention relates to fish farming, can be used in fish farms, and is complementary to the main author. St. No. 824921.

The aim of the invention is to improve the conditions of the fish by increasing the degree of water purification.

Constructive execution of the device allows for deeper water purification by removing not only the device. The device also has a fine water purification chamber 12 and a sump 13, the lower part of the foam collection chamber 9 is connected to the fine cleaning chamber 12 and the upper part 15 to the sump 13. The chamber 12 of fine cleaning is equipped with a closed belt conveyor with a drive (not shown) and a release device in the form of a roller 16. The conveyor belt 17 is made of elastic porous

Nivayush, their impurities, as well as those that Q-material, such as polyurethane foam. The loam after the formation of foam remained in the water. This, in turn, provides an improvement in the viability of the fish by increasing the efficiency of aeration, since with a decrease in the amount of impurities in the water, the amount of oxygen that is involved in its natural oxidation decreases, and the proportion of oxygen directly increases. fish.

The drawing shows the proposed device, a vertical section.

A device for aerating water in a tank with live fish contains a tank 1 for live fish, a pipe 2 for circulating water with a pump 3 installed on it and an aerating device — a fine cleaning injector 12 is connected by pipe 18 to a chamber 5 for foaming water and pipe 19 with a sump 13, which has a removable cover (not shown).

The device works as follows.

The water taken from the tank 1 by the pump 3, having passed the injector 4, flows in mixture with air through the outlet section 7 of the pipeline 2 into the chamber 5. The released air bubbles and the gases dissolved in the water begin to float upward, where they are affected by the rotating plate 8, as a result of which they are crushed into smaller bubbles. The foam forming a fine mesh fills the upper part of chamber 5

rum 4, chamber 5 for foaming water, bottom 25 and through pipeline b enters chamber 9

The part of which is connected with the tank 1, and the top has a pipeline 6 for the removal of foam. The outlet section 7 of the pipeline 2 is introduced into the Chamber 5. In the chamber 5 below the water level is installed above the exit portion of the collection of foam. The biogenic components due to the centrifugal forces are deposited on the walls of the chamber 9 for collecting foam and in the filter 11, and the water flows to the bottom of the chamber 9, from where it passes through the pipeline 14 to the chamber 12

clod 7 of conduit 2 plate 8 with drive 30 for fine water purification, where

the house (not shown) is designed to rotate around a vertical axis. The device has a foam collection chamber 9, to the top of which a conduit 6 is connected to remove the foam. Inside the camera

in water, contaminants that have not fallen into foam enter the closed tape 17, which absorbs them. The roller 16 squeezes out the concentrate of contaminations from the belt 17, which enters the settling chamber 13 through the pipeline, a plate 10 is installed with a drive (not 35 ° 19, but purified water through the pipeline

shown), made with the possibility of turning the-18 back into the container 1 and the camera 5.

For example, mesh, located below the pipe 15 foam from the upper part of the rotation of the plate plate 10. measures 9.
