Description

2. The device according to claim 1, about the fact that, in order to stop the withdrawal of the mixture when its level drops below the permissible, part of one of the mixing elements has a profile that matches the profile of the inlet port of the outlet of the mixture.

3. The device according to PP. 1 and 2, it is understood that, in order to keep the mixing elements in the zone of the mixture outlet pipe, the narrowed parts of the mixing elements are connected - between each other by a flexible connection.

The invention relates to mixing device designs and can be used to mix homogeneous substances such as liquids. Mixing devices are known that contain a mixing tank, provided by the channels for feeding the components being mixed to the sources of these components, and an outlet for evacuating the final product. A spinner with an individual drive for its rotation is placed in the tank. Lj The disadvantage of such mixing devices is the need for separate drives for rotating 1 mixing means, which reduces the energy performance of these devices. Devices are known in which the stirring means is hingedly connected to the reservoir and is driven by its oscillations 2j. However, this device is inefficient in fixed tanks. The closest to the proposed technical essence and the achieved result is a mixing device containing a vertical casing with nozzles for mixed water: liquids and for discharging the finished product, mixing elements with blades fixed in it on their walls, and loads Z j The disadvantages of the prototype are the passive mixing mode, a limited zone of influence on the mixture — the lower part of the Body at the height of the blades, strong resistance to flowing medium. The aim of the invention is to improve the quality of the finished mixture when the liquid level in it changes. This goal is achieved by the fact that in a device for mixing liquids containing a vertical body, mixing elements placed in a body, blades fixed on the outer surface of the mixing elements, weights placed inside the mixing elements, and nozzles of entering liquids and withdrawing the finished mixture, mixing elements made hollow pear-shaped and directed narrowed parts down. In order to stop bleeding when the level drops below the allowable, the lower part of one of the mixing elements has a profile that corresponds to the profile of the input branch of the blend outlet. In order to keep the mixing elements in the zone of the mixture outlet, the constricted parts of the mixing elements are interconnected by a flexible connection. The drawing shows the proposed device, a longitudinal section. The mixing device contains a vertical body 1 with a mixing chamber 2 made in it, hollow mixing elements 3 placed in the chamber, blades 4 mounted on the outer surface of the mixing elements, weights 5 placed inside the mixing elements 3, inlets 6 and 7 of the inlet components and the output of the finished product, a flexible thread 8 connecting the lower parts 9 of the mixing elements 3, made of a pear-shaped

forms, with spherical upper parts 10, on which blades 4 are located, with loads 5 placed in the lower parts 9 of mixing elements 3,

The device works as follows.

The agitated components, which are predominantly homogeneous, such as liquids, flow through the nozzles 6 into chamber 2. Due to the outflow of liquids into the nozzle 7, they twist, causing the rotation elements 3 to rotate. The mixing of components with a complex surface of bodies and blades 4 occurs due to buoyancy. 3, they periodically move vertically, then are drawn in by the flow, then they float up and are oriented in the upper part of the fluid volume. When the mixing elements 3 of the pear-shaped form are made, their tight part is oriented downwards towards the nozzle 7, which contributes to more intensive mixing due to the precision rotation of their axis. When the supply of fluid is interrupted, the mixing elements 3 fall to the bottom of chamber 2,

and one of the free most heavy elements is lowered by the neck into the valve 11 (see drawing), blocking the outlet nipple 7. The design of the mixing elements ensures the automatic switching of the device into operation with a sufficient volume of soybean components. When the filling of the reservoir to the HSS occurs, corresponding to the ascent of the mixing elements, the opening of the branch pipe is opened by the mixing process. In addition, mixing elements can serve as indicators of the composition of the mixture, as well. and percentage of components. If the specific gravity of the component fluids is exceeded, the ascent of the mixing elements does not occur. This is achieved by finely weighing the bodies or one of them, the heaviest.

The use of the invention allows to intensify the process, to provide high-quality mixing while simplifying the design of the device. In addition, the addition or removal of mixing elements makes it possible to select the best mixing mode for different tank volumes.
