Mo 6.|, which consists of a body, a radial perforated pipe for removing the mixture, a circulation nozzle, a reagent supply nozzle, reagent outlet holes, a reagent mixing chamber, tangential supply pipelines for reagents, and a cone sealer for float sludge.

The disadvantage of the closest analogue is the low degree of mixing of reagents with wastewater, structural imperfection of the working chamber of the reagent supply nozzle, and limited functionality.

The useful model is based on the task of improving the apparatus for mixing aqueous solutions and dosing reagents by making the inner diameter of the reagent supply nozzle semi-conoid, which increases the degree of dissolution of reagents, ensures the reliability of the equipment and expands the functional capabilities of the apparatus.

The set task is solved by the fact that in the apparatus for mixing aqueous solutions and

From the dosing of reagents, which contains the body, radial perforated pipelines for the mixture removal, circulation nozzle, reagent supply nozzle, reagent outlet hole, reagent mixing chamber and tangential supply pipelines for reagents, conical sludge slurry sealer, according to the useful model, the inner diameter of the reagent supply nozzle is made semiconoidal shape.

Making the inner diameter of the reagent supply nozzle semi-conoidal increases the speed of water flow in the live section of the reagent supply nozzle, ensures the intensity of mixing of reagents with wastewater and increases the degree of reliability of the device.

The essence of the useful model is explained by the drawings, where in fig. 1 presents the structural and technological diagram of the device (general view, front section); in fig. 2 - a reagent supply nozzle with an inner diameter of a semi-conoidal shape (the general view is a longitudinal, vertical section).

To determine the structural dimensions of the apparatus for mixing aqueous solutions and dosing reagents, the following geometric notations are used:

Bi - the average, smallest, diameter of the nozzle 4 of the reagent supply with the inner diameter of a semi-conoidal shape (section at the level of the B-B line, longitudinal vertical section); p»: - the upper diameter, located at the height Ne, nozzle 4 of the reagent supply with the inner diameter of a semi-conoidal shape (section at the level of the B-B line);

Oz - the lower diameter - the nozzle, located at the height of Ne, nozzle 4 of the reagent supply with the inner diameter of a semi-conoidal shape (section at the level of the C-C line);

No - the total height of the nozzle 4 of the reagent supply with the inner diameter of the semiconoidal shape (general view).

The apparatus for mixing aqueous solutions and dosing reagents includes a body 1, radial perforated pipes 2 for the removal of the mixture, a circulation nozzle 3, a nozzle 4 for the supply of a reagent, with an inner diameter of a semi-conoidal shape, an opening 5 for the exit of a reagent, a chamber 6 for mixing a reagent and pipelines 7 for the tangential supply of reagents , cone sealer 8 of floating sludge.

The apparatus for mixing aqueous solutions and dosing reagents works as follows.

The treated water enters the lower part of the housing 1 of the apparatus, enters the circulation nozzle 3, where it is mixed with reagents supplied from the upper part of the housing 1 of the mixer through the reagent supply nozzle 4, the inner diameter of which is semiconoidal in shape, which significantly distinguishes this design of the device from other similar designs.

Next, the solution of water and the reagent fills the radial perforated pipelines for the discharge of the mixture. At the point of connection of the perforated pipelines to the body 1, the flow rate increases, which contributes to the appearance of additional vortices when mixing the solution, the formation of uneven movement of the water flow, which creates uneven conditions for the movement of the water flow with the reagent solution.

Making the inner diameter of the semi-conoidal reagent supply nozzle 4 has a positive effect on the movement of the water flow in the downward direction: from top to bottom, which significantly reduces the supports inside the device, and has a positive effect on the hydrodynamic processes that are formed in the operating conditions of circular cross-section devices.

The proposed design of the inner diameter of the nozzle 4 of the semi-conoidal reagent supply device for mixing aqueous solutions and dosing reagents increases the power of water treatment equipment, expands the possibilities of using various types of reagents and ensures the efficiency of wastewater treatment of industrial enterprises.
