Abstract

The invention relates to the technology of mixing fluid media and can be used in processes where contact of the mixed media with air is acceptable. The invention makes it possible to increase the reliability of the design and to intensify mixing. Liquids, which are not stirred, are supplied to tank 1. Float 4 with stirrer 3 is above the bottom of the tank. Compressed air is supplied to bubbler 7 through line 2. Air accumulates in cavity 5, partially out through the throttling holes 8. When enough air accumulates in cavity 5, the float begins to float, slipping along the guide post 6. The liquid is stirred by a stirrer 3, air bubbles coming out of the holes 8, and excess air, coming out from under the bottom edge of the float 4. The rotation of the float promotes intensive mixing. When the float reaches the surface of the liquid, the air supply is stopped. The air is vented through the holes 8 and the float starts to fall, rotating in the opposite direction. 1 hp f-ly, 2 ill. , i (Л С

Description

The invention relates to devices for mixing liquid media and can be used in all sectors of the national economy, where mixing processes are used and where contact is allowed to move media with air.

The aim of the invention is to simplify and increase the reliability of the construction and intensification of mixing.

Fig. 1 shows a device for mixing a liquid, a slit; FIG. 2 is a section A-A in FIG. 1;

The device for mixing the liquid contains a container 1 with a pipeline 2 for supplying compressed air-/, ha, stirrer 3 connected to a float 4, made in the form of a bowl, installed upside-down, with a cavity 5, freely seated on the central rack 6, a bubbler 7, mounted at the bottom of the tank 1 under the float 4 and connected to the pipe 2 of the compressed air supply. The float has tangentially directed throttling holes 8, and inclined vanes 9 are fixed on its outer side walls. The mixer 3 is made in the form of a lattice.

The device for transferring the liquid works as follows.

The liquids suitable for mixing are supplied to the tank 1 in certain proportions through the process connections (not scooped). Pop315

The blender A with the stirrer 3 is in the lower position - lying on the bottom of the tank 1. After filling the tank 1 to the working volume, the mixing process starts by supplying compressed air through the pipeline 2 n to the bubbler 7. Air bubbles, leaving the bubbler 7, the passage is not high until the liquid layer, determined by the height of the cavity 5 of the float 4, starts the mixing process. At the same time, part of the air leaves through the throttling holes 8, facilitating the process of mixing the liquid outside the float 4. Part of the air accumulates in the cavity 5 of the float 4, being simultaneously displaced from this cavity, liquid. After a sufficient amount of air has accumulated under the float 4 in its cavity 5, the float 1a snaps up to the surface of the dryness, slipping along the guide of the central stand 6. During the process of lifting float 4 with the stirrer 3, the liquid passes through a large number of holes of the stirrer 3 Subscribe to intensive mixing. Simultaneously with the upward translational movement, the Float 4 s behind the agitator 3 mounted on it rotates around the central pillar 6 from the effect of the liquid on the inclined vanes 9, thereby strengthening the process of mixing the liquid. Rotational motion of the float 4 is also promoted by air jets emerging from tangentially throttling holes 8 made. Excessive

air, B1.1 code pu1e from under the lower edge of the float 4 and from the throttling holes B, together with the blades 9 in the process of rotation, the increment 4 additionally move the liquid. The float 4 with a stirrer 3, reaching the surface of the liquid, is kept afloat until the air supply is stopped. When the air is disconnected and released from the cavity 5 through the throttling holes 8, the float 4, under the influence of gravity, begins to gradually descend to the bottom of the tank 1, rotating in the opposite direction around the central post 6 from the impact of the liquid on the blades 9.
