Description

The utility model is intended for the purification of water supplied to hatcheries from mechanical impurities (feces, residues of feed, sediments and other mechanical particles) by means of a drum micro-mesh filter. It is used in industrial complexes of fish growing in the systems of ultrasonic testing, SOW.

A known unit for the mechanical cleaning and degassing of water entering fish hatcheries from mechanical impurities (feces, residues of feed, sediment and other mechanical particles) by means of a drum micro-mesh filter (aquatechnology. Rus.), Into which water from fish hatcheries by gravity (without destroying the structure feces and other contaminants), enters the inner part of the drum filter driven by an electric motor gearbox and passes through a microgrid with a mesh size of 40, 56 or 80 microns, as a result of It is cleaned of mechanical impurities that settle on the inside of the filter and are washed out from there by means of high pressure nozzles into a specialized tray and, with a certain amount of water, are drained into the sewer through a sand trap. Further, the purified water through the pumps enters the fish tank.

The disadvantages of this design are the low efficiency of water treatment and its low quality, in addition, when replacing the mesh of a drum filter with a mesh of a different diameter or as a result of a breakdown of the filter, it becomes necessary to stop it.

A known water treatment system (patent for utility model No. 153511, IPC C02F 1/24, published on July 20, 2015, bull. No. 20) is made of polypropylene in the form of a rectangular body equipped with a horizontal stiffener, made at a distance from the bottom of the body. The housing contains a pipe connected to the neck of the drum filter, supplying source water, equipped with a pump. The neck of the drum filter, in turn, rests on two rollers, and its second end the drum filter is connected to a gearbox with a motor, which is located on the outer platform, the drum filter is fixed mainly horizontally. The contaminant discharge pipe is connected to the drum filter tray, in addition, the system includes a purified water discharge pipe. The water level control unit in the module is made in the form of a control sensor and a submersible pump for pumping purified water. The drum filter contains a grate with a cell diameter of 4-8 mm, fitted with a microgrid with a cell diameter of 40-100 microns, and washing nozzles in an amount of 4-12 pieces.

The disadvantages of this design are the low efficiency of water treatment and its low quality, in addition, when replacing the mesh of a drum filter with a mesh of a different diameter or as a result of a breakdown of the filter, it becomes necessary to stop it.

The technical task of the utility model is to increase the efficiency of water purification and its quality, reduce the cost of equipment, save wash water in industrial complexes of fish farming.

The problem is solved in a two-stage drum filter for mechanical water treatment, located horizontally in a rectangular housing (1) made of polypropylene, and connected to a gearbox (2) with a motor (3), characterized in that the housing (1) is separated at a distance from each other from each other by two vertical partitions (4) into two steps, in one of which there is a drum filter (6) with a microgrid with a mesh size of 30-40 microns, and in the other - a drum filter (5) with a microgrid with a cell size of 90 microns, connected by a shaft (7), in addition, a pipe (11) is sealed in the holes of the vertical partitions (4) for transfusion of water from one part of the body to another. A pipe (10) is installed in the side wall of the housing (1), through which water for fish breeding pools enters the inside of the drum filter. Inside each drum there is a horizontally located tray (12), on which, when washing the nets with the help of high-pressure nozzles, contaminants get in and are disposed of into the sewer through the hole (13) in the wall of the housing (1).

The technical result of using the proposed design is to increase the efficiency of water purification and improve its quality due to passing through two stages of a filter with a microgrid with different cell sizes, the installation cost is also reduced as one drive, one pump is used to operate both filter stages, when replacing grids on one of the steps there is an opportunity not to stop the system.

конструкции.A two-stage drum filter for mechanical water treatment is represented by the following drawings. In FIG. 1 - general view; in FIG. 2 - top view; in FIG. 3 -

designs.

The utility model consists of a housing 1 made of polypropylene and connected to a gearbox (2) with a motor (3) located at a distance from each other between two vertical partitions (4), dividing the housing into two steps, in one of which there is a drum a filter (5) with a microgrid with a mesh size of 90 microns, and in the other a drum filter (6) with a microgrid with a cell size of 30-40 microns connected by a shaft (7), in addition, a pipe (11) is sealed in the holes of the vertical partitions (4) for transfusion of water from one part of the core Usa to another. Inside each drum there is a horizontally located tray (12), on which, when washing the nets with the help of nozzles, contaminants get in and are disposed into the sewer through the hole (13) in the wall of the housing (1).

A two-stage mechanical filter operates as follows.

Water for fish tanks (incubators) with mechanical impurities (feces, residues of feed, sediments and other mechanical particles) by gravity through the hole (10) located in the side wall of the housing (1) enters the receiving chamber of the first stage (9) of the drum filter, passing through a filter mesh with a larger mesh size, having cleaned of large feces, by gravity flows through the pipe (11) into the second stage 8 of a drum filter with a filter mesh with a smaller mesh size, passing through this mesh, water Erez opening (14) in the wall of the housing (1) is fed back into the fish tanks (incubator). As the grids become contaminated, high-pressure nozzles are turned on, the grids are washed, contaminants from the grids fall onto the tray (12) and are disposed of through the hole (13) into the sewer. When the filter mesh becomes dirty, the water level rises, does not pass through the filter, the water level sensor (not shown) is activated, the pump for washing the mesh (not shown) is turned on. This design allows you to retain large contaminants in the first stage of the drum and clean up with great effect in the second stage.
