Description

The invention relates to fish farming, in particular to devices for growing fish and other aquatic organisms.

The aim of the invention is to simplify the design, reduce material consumption, improve the living conditions of aquatic organisms and ease of maintenance, increase plant productivity.

The drawing shows the installation diagram.

The plant for growing fish and other aquatic organisms consists of a cylindrical pool (1), a circulation pump (2), a mechanical filter (3), a heat treatment unit (4). oxygenator (5). The cylindrical pool (1) has a complex conical bottom, in the central cone (8) of which there is a guard grid (9). Inside the pool (1), a cylindrical partition (7) is installed. which can be moved in the vertical direction by means of a screw connection (10). In this case, the size of the gap (16) between the conical bottom of the pool and the lower part of the cylindrical partition (7) is regulated. The gap, depending on the size of aquatic organisms, should prevent them from entering the biological filter zone. For small aquatic organisms, it is planned to install a mesh 1804295 AZ cuff with the required size of holes on the lower edge of the cylindrical partition.

The cylindrical partition (7) defines the compartment for the biological filter from the fish tank (1). In this cylindrical compartment, a floating load (6) is filled up. An easily removable annular water distribution tray (12) with a perforated bottom is required above the biological filter on the radial rods (11) of the cylindrical partition, which is necessary for uniform distribution of water along the filter load. The removability of the tray is due to the fact that it does not attach to anything, but only lies on the radial rods. The mechanical filter (3) has a pipeline for supplying the washing mixture (13) and sludge discharge (14). The thermal water treatment unit (4) has a system for heating and cooling water to optimal values, thermal sensors.

Installation works as follows.

Fresh water is supplied to fill a closed system or to make up for losses (evaporation, washing of a mechanical filter) through a pipeline (15). After filling the installation with water, it turns on the pump (2). Aquatic organisms are placed in the interior (16) of the basin. Before this, the necessary (depending on the size of aquatic organisms) clearance is established between the cylindrical partition Ts7) and the conical bottom. Contaminated water from the pool (1) is pumped through a bar (9) to a mechanical filter (3), where water is purified from large contaminants. Filtered water, falling into the heat treatment unit (4), is heated or cooled depending on the specified parameters necessary for the normal life of aquatic organisms. Next, part of the water enters the oxygenator (5), the other part to the water distribution tray (12). In a low pressure oxygenator (5), water, saturated with oxygen to the required concentration, enters the inner part of the basin (16) and the water distribution chute (12). Water through the water distribution tray (12) is evenly distributed over the floating loading of the biofilter (6), where it is biologically cleaned. The resulting excess active bacterial film of the biofilter during washing, precipitating through gap 17, enters the pool with aquatic organisms. Active film is an excellent food for some types of aquatic organisms and this increases the efficiency of the installation.

The layout of the biofilter and fish tank in a single unit allows you to reduce material costs by 30%, significantly reduce the occupied area by 20%, and significantly simplify the installation.
