The disadvantage of the analogue device is the low degree of mixing of reagents with wastewater, the hydraulic resistance that occurs when the flow of the aqueous solution is introduced, and the increased hydraulic loads in the operation of treatment facilities.

The useful model is based on the task of improving the apparatus for mixing aqueous solutions and dosing reagents by making the inner surface of the reagent supply nozzle 4 of a spiral ribbed shape, which allows to reduce hydraulic resistances, increase the mixing of reagents with wastewater and expand the functional capabilities of the apparatus.

The task is solved by the fact that the apparatus for mixing aqueous solutions, sewage

From water and dosing of reagents, it contains a housing, radial perforated pipelines for the removal of the mixture, a circulation nozzle, a reagent supply nozzle, a hole for the exit of the reagent, a reagent mixing chamber and pipelines for the tangential supply of reagents, a conical seal for floating sludge. The inner surface of the reagent supply nozzle is spirally ribbed.

The inner surface of the spiral ribbed 9-shaped reagent supply nozzle creates conditions for more effective mixing of the water flow, which consists of two or more components, and this increases the speed of the flow and creates conditions for the appearance of additional vortices when mixing solutions.

Drawings explain the essence of a useful model.

In Fig. 1 presents the structural and technological scheme of the apparatus for mixing aqueous solutions, wastewater and dosing reagents (longitudinal vertical section).

In Fig. 2 - the inner surface of the reagent supply nozzle is made of a spiral ribbed shape (View A, sweep of a longitudinal vertical section, the spiral ribbed shape is indicated by dotted lines).

The proposed design of the device for mixing aqueous solutions, waste water 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 supplying a reagent, the inner surface of a nozzle 4 for supplying a reagent is made of a spiral ribbed 9 shape, a hole 5 for the exit of a reagent , the reagent mixing chamber 6 and pipelines 7 for the tangential supply of reagents, and the conical seal 8 of the floating sludge.

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

The processed water enters the lower part of the housing 1 of the apparatus, enters the circulation nozzle 3, where it is initially mixed with the reagents supplied from the upper part of the housing 1 of the mixer through the reagent supply nozzle 4. The mixture 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.

In order to improve the efficiency of mixing aqueous solutions, wastewater and dosing of reagents, the ribbed shape of the inner surface of the nozzle 4 of the reagent supply contributes to the minimization of hydraulic resistance in the case of movement in a downward flow.

The inner surface of the nozzle 4 of the supply of the reagent is made of a spiral ribbed 9 shape, which allows to reduce hydraulic resistances and fully contribute to the optimal movement of the downward flow for mixing aqueous solutions, wastewater and dosing reagents.

The inner surface of the nozzle 4 of the reagent supply is made of a spiral ribbed 9 shape, which creates conditions for more effective mixing of the water flow, which consists of two or more components, and this increases the speed of the flow and creates conditions for the appearance of additional vortices when mixing solutions.

Thus, the proposed design of the device for mixing aqueous solutions, wastewater and dosing reagents reduces hydraulic resistance, increases the mixing of reagents with wastewater, and extends the functional capabilities of the device.
