Description

The utility model relates to water treatment technology for domestic and technical consumption and can be used to disinfect running water.

The well-known "BACTERICIDAL DEVICE FOR WATER DISINFECTION ON UNDERWATER INHABITED OBJECTS" US 7,166,216 [1], comprising a housing with nozzles for supplying and discharging water, an irradiation chamber with germicidal ultraviolet lamps and swirls located in its cavity in the form of a U-irradiation chamber, the chamber is made a shaped tube, in each of the side sections of which an ultraviolet lamp and a swirl of water flow are coaxially mounted.

A disadvantage of the known design is the increased dynamic resistance to water flow and the high material consumption of the swirler (turbulizer) of running water.

Closest to the claimed technical solution is the "Operational unit of the water treatment system" US 7,166,216 [2], containing a turbulator containing inclined blades (mainly trapezoidal, with the sides oriented along the radii and the blades cut along an open circuit) and the central region ( central ring), with the blades adjacent to the (single-angle) bend (formed by the bending operation) to the common part of the part (fig 15).

The known turbulizer has less dynamic resistance to water flow compared to [1].

A disadvantage of the known turbulizer is insufficient mechanical strength and rigidity, insufficient stability due to the possibility of flutter of the blades and insufficient durability due to increased fatigue of the material under conditions of increased bending forces in the areas of bending of the blades.

The technical result of the proposed utility model is to increase mechanical strength and stiffness, increase stability, increase durability.

The technical result is achieved by the fact that the turbulator, (a swirler installed in the device for disinfecting water with ultraviolet radiation, made of a flat blank of circular shape), containing (flat) inclined blades (mainly trapezoidal, with the sides oriented along the radii and the blades themselves decorated by notching a flat workpiece along an open loop) and the common central part of the part in the form of a central flat ring, (the plane of the ring is perpendicular to the axis of turbulization ator) is characterized by the fact that it additionally contains a flat annular jumper located along the perimeter of the turbulator (the plane of the annular lintel coincides with the plane of the central ring), and between the central ring and the annular jumper there are (flat) radial lintels (whose planes coincide with the plane of the flat central ring ), to the sides of which the blades adjoin with a bend (each blade adjoins with a single-angle bend, formed by the bending operation, between each flat plane dial jumper and flat blade).

The angle of inclination of the planes of the blades can be 25 ± 5 degrees. The specified angle allows you to achieve a high rotational component of the flow around the UV emitters with a sufficiently low resistance to the incoming water flow.

At least one jumper may have additional holes. The presence of additional holes will simplify the installation of the device, for example, by assembling the fastening elements of the irradiating lamps on the turbulator.

Top view of a blank of a turbulator made using PP. 1 and 2 of the Formula are shown in FIG. 1, in FIG. 2 is a side view of the finished product; FIG. 3 is a top view of the finished product; FIG. 4 example of the assembly of the turbulator as part of the assembly of the unit of the device for water disinfection, general appearance, where:

1 - blades;

2 - a flat central ring;

3 - a flat ring jumper;

4 - radial jumpers;

5 - bending lines;

6 - additional holes.

The turbulator operates as follows: the blades 1 direct the flow of water around the axis, providing an improvement in the action of the water disinfection device (not shown). The flat central ring 2 together with the flat annular jumper 3 along the perimeter and the radial lintels 4 concentrate the water flow on the blades and, at the same time, fix the blades that are adjacent to the radial lintels along the bending lines 5. Additional holes 6 serve to fix the remaining parts of the assembly and fixing the turbulator itself in the water disinfection device.

The technical result is an increase in mechanical strength is achieved by the fact that the design with a flat central ring and a flat annular jumper, interconnected by radial jumpers has increased rigidity and strength. The blades adjacent at an angle to the radial bridges form stiffeners, which additionally increase the strength and stiffness of the radial bridges and the design of the turbulator as a whole.

EFFECT: increased stability of operation due to a significant decrease in the possibility of flexural-torsional flutter of the blades and a corresponding decrease in the instability of the water flow.

The technical result is an increase in durability due to a decrease in the deformation of the blades in the bending region, due to the increased length of the bending line and the decrease in the bending moment on the blades caused by the water flow, and, accordingly, less material fatigue during operation.

Industrial application. The utility model can be successfully used for the production of turbulators for water disinfecting devices using ultraviolet radiation.
