Description

The proposed utility model relates to the field of technological equipment for the preparation of multicomponent solutions, emulsions and suspensions with a liquid component.

At present, in connection with the intensification of production, in particular in oil refining and petrochemicals, the most important component of the latter is becoming highly efficient equipment based on the latest technologies based on wave technology, which have found application in electric desalination plants and in the preparation of motor and transmission oils and receiving bitumen.

Mixing devices are one of the most common types of technological equipment, without which practically no technological chain can do in oil refining and petrochemicals.

Therefore, this type of equipment has special requirements for performance, product quality, and multifunctionality of application.

The development of new types of such equipment using fundamentally new technologies at present, especially for Russia, is a fundamental task.

A large class of faucets is known (1), the basis of which is the mechanical effect on the liquid mixture created by a screw as a conventional household mixer.

The disadvantages of such devices are low productivity, the inability to achieve high levels of dispersion of the mixture.

Known vibratory type mixers (2), where for the preparation of the mixture using fluctuations in the capacity of the liquid mixture placed in it, mounted on a vibrating device.

The disadvantages of such devices are:

- bulkiness and complexity of the design;

- high energy consumption for the preparation of the mixture;

- insufficient level of quality dispersion of the mixture;

low productivity.

Known mixers of the combined type - hydrodynamic oscillation generators (3), where in a liquid medium passed through them at a certain speed and pressure, additional vibrations of sound or ultrasonic frequency are formed, i.e. the mixed liquid medium experiences stresses from both simple mechanical movement and the vibrational type with a certain frequency, which results in an increase in the mixing efficiency of the components with the possibility of obtaining mixtures with a high degree of dispersion.

The disadvantages of such devices are a decrease in the productivity and quality of the product when changing the type of the liquid component of the mixture, which requires the mandatory reconfiguration of the speed and pressure parameters of the liquid medium moved by the pump and the hydrodynamic oscillation generator itself when changing the liquid component of the mixture.

This device (3) is taken as a prototype of the proposed, as the closest to the proposed technical essence and the achieved technical result.

The task that the authors set for themselves when developing the proposed mixing device was to increase the productivity of the device and expand the range of manufactured mixtures without compromising the quality of the product.

The problem is solved in a device containing a container for placing components, nodes for loading components and removing the finished product, a node for generating a combined physical effect on the components to be mixed in the form of at least two hydrodynamic oscillation generators installed at some distance from each other in the vessel with different parameters of the oscillation frequency of the flow medium connected to the pumping unit of the mixed components.

New significant features of the proposed device are:

- the implementation of the node forming a combined physical effect on the mixed components in the form of at least two hydrodynamic oscillation generators with different parameters of the oscillation frequency of the flow medium;

- installation of hydrodynamic oscillation generators in the tank at a certain distance relative to each other;

- connection GDGK to the pumping unit of the mixed components.

In particular cases of implementation in the device:

- the pumping unit of the mixed components is made in the form of a hydraulic motor with a speed controller located outside the tank, the output of which through an adjustable valve is connected to hydrodynamic oscillation generators, and the input to the drain hole from the tank;

- the unit for removing the finished product from the tank is made in the form of a tap with a shut-off valve in the pipeline between the motor and the drain hole from the tank.

New significant features in particular cases of device implementation are:

- implementation of the pumping unit of the mixed components in the form of a hydraulic motor with a speed controller located outside the tank, the output of which through an adjustable valve is connected to hydrodynamic oscillation generators, and the input to the drain hole from the tank.

- the implementation of the node for removing the finished product from the tank in the form of a tap with a shut-off valve in the pipeline between the motor and the drain hole from the tank.

According to the authors, despite the fame of the components and elements making up the device, the proposed new layout made it possible to increase its productivity and expand the range of manufactured mixtures without compromising product quality, which allows us to consider the new features mentioned above significant.

The proposed structural diagram of the proposed device is presented in the attached drawing.

The device has a capacity 1, with a component loading unit made in the form of at least two corresponding trays 2, 3 with locking elements 4, 5.

In the tank 1 at a certain distance from each other are fixed two hydrodynamic oscillation generators 6, 7 providing different parameters of the oscillation frequency of the flow medium connected to the pumping unit of the mixed components.

The latter is made in the form of a hydraulic motor 8 located outside the tank 1, the output of which through an adjustable valve 9 is connected by a pipe 10, introduced into the tank 1 through the hole 11, with branches 12, 13 to the inputs of the hydrodynamic oscillation generators 6, 7, and the input through the pipe 14 to the outlet 15 of the container 1.

To drain the finished product from the tank 1 in the pipe 14, a tap 16 is made with a valve 17.

The hydraulic motor 8 is equipped with an element for adjusting the number of revolutions, for example, in the form of a current regulator 18.

The current controller 18 in conjunction with an adjustable gate valve 9 allows you to adjust the speed and pressure of the flow of pumped mixed components to the values necessary to ensure the operation of hydrodynamic oscillation generators 6, 7.

All components of the device are standard manufactured by the industry.

The operation of the device is as follows.

Suppose two components are loading. The valve 17 closes. The shut-off valves 4, 5 open and through the loading trays 2, 3 the components are loaded into the tank 1.

The hydraulic motor 8 is turned on.

Mixed components move along the technological chain: valve 9, pipeline 10, branching 12, 13, hydrodynamic oscillation generators 6, 7 capacity 1, outlet 15 of capacity 1 pipe 14, hydraulic motor 8.

Knowing the type of the liquid component (s) and the volume of the tank, the flow speed and pressure parameters are regulated by the current regulator 18 and by moving the valve 9 to the values necessary for the hydrodynamic generators to generate oscillations 6, 7 in the liquid flow of the mixed components passed through them, vibrations in the sound or ultrasonic ranges.

As a result of such a combined effect on the components moved through the hydrodynamic oscillation generators, a mixture is obtained whose disperse properties exceed the performance of mixtures obtained by traditional technologies, with a productivity several times higher than that of traditional technologies.

After the time required by the technology, the hydraulic motor 8 is turned off and the resulting product is drained by gravity through the outlet 16, opening the valve 17.

An important point in the operation of the proposed device is that the impact on the components of the mixture passed through hydrodynamic oscillators of different frequencies (this is ensured by the designs of hydrodynamic oscillators) allows to obtain a high dispersion of the mixture even when the type of the liquid component of the mixture is changed in a certain range of its parameters, which allows to do without additional adjustments and increase the productivity of the device.

Currently, a prototype of the device has been manufactured at the enterprise and its tests have been carried out, confirming the achievement of the technical effect set forth in the application.
