Description

The invention relates to a technique of mixing liquid media with mixing devices and can be used in the chemical, petrochemical, petroleum and other areas of the industry where the mixing processes of liquid media are carried out.

The purpose of the invention is to increase the efficiency of the apparatus.

Figure 1 schematically shows the apparatus, a general view; figure 2 - section aa in figure 1; on fig.Z - view along arrow B in figure 1.

The apparatus contains a tank 1, in which a rotating agitator 2 is located.

Reflectors 3 are fixed to the vessel wall, along the entire height of which there are through inclined channels 4 formed by guide elements 5. The directing elements of the partition are connected to a plate 6 having an opening 7 located at the inlets of the inclined channels 4.

The inclined channels in one partitions are directed upwards, and the partitions alternating with them are directed downwards.

The tank is equipped with nozzles 8 for supplying components and nozzles 9 for draining the mixture.

The device works as follows

The container 1 through the nozzles 8 is filled with two liquid components, then the gearmotor 10 is turned on, which causes the rotation of the stirrer 2, resulting in the rotation of the liquid components in the tank 1: and mixed, forming a homogeneous mixture. The fluid rotating along the peripheral part of the tank 1 flows through the holes 7 in the plates 6, forming streams that fall into the inclined channels 4. The elements 5 direct the fluid flow up and down after odd partitions, then down after even. Thus, the holes 7 in the plates 6 eliminate the formation of stagnant zones on the back side of the partitions 3, and the elements 5 change the direction

fluid movement along the peripheral part of the tank 1.

After the calculated mixing time, the homogeneous mixture is drained from the tank 1 through the pipe 9

If necessary, the processes of pouring the components, mixing them and draining the mixture are repeated many times.

The application of the proposed technical solution will make it possible to increase the efficiency of mixing the liquid components in devices with mixing devices and baffles by organizing more hydraulically more advanced processes of fluid movement in the peripheral part of the tank, where the baffles are located. This is achieved by alternately changing the direction of fluid flow after each baffle along the wall.

capacity. These phenomena improve the mass transfer processes inside the tank with the mixing of the components, which determine the mixing effect.
