Description
Mixing Device
Field of Technique
The invention is concerned with an apparatus for the intense mixing of hard, liquid, gaseous materials until a homogenous mixture is obtained.
Prior art
Different types of apparatuses for mixing 'are known. Depending on the physical condition of the components these apparatuses are used for. mixing of gasses, mixing in liquid environment, mixing in solid environment. Usually the mixing in a liquid environment is performed mechanically and the working elements have different shapes. In particular cases the mixing can be accomplished by the use of gasses, for example, air (pneumatic mixing), or regular pumps. The usage of pneumatic mixing or pumps has limited application because of the greater power consumption. During the mechanical mixing the mixer consists of a lease, which rotates directly or through a reductor by an electric motor. Depending on the shape of the working elements, they are classified as follows: blade type, propeller type, turbine type and special type.
For example, a known mixer of blade type normally includes a body, in which a shaft is located, driven directly or through a reduction gear by an electric motor. One or more blades are fixed at the end of the shaft.
A shortcoming of the conventional mixing devices is the necessity for the driving of the main working element of the mixing devices, which results in increased power consumption and the effectiveness of the process depends on dimensions of the mixing vessels and the duration of the process, which occurs periodically.
Summary of the Invention
The aim of the current invention is to create a mixing device which insures effective stirring and mixing of components at reduced power
consumption and reduced duration of the process, taking place in vessels with considerably reduced dimensions in an uninterrupted manner.
The aim is achieved by creating a mixing device, which includes a body along the axis, on which a rod is located and an orifice for the discharge of the obtained mixture is fixed in the lower part of the body. The mixing device is characterized in that the rod along its length has segmented blades located at an angle to the axis of the rod and rotated at an angle from each other so that the rod is firmly fixed to the body.
In one variant of accomplishment of the mixing device the body has cylindrical shape.
In another variant of accomplishment the blades have a circular segment profile.
It is suitable for both ends of the cylindrical body to be coned, so that at least one orifice is fixed in the upper conic part, at an angle to the axis of the body which charges the second component.
It is suitable in this preferred variant of accomplishment the angle of allocation of the second orifice to be 45°.
The advantages of the mixing device, according to the invention lay in that it provides effective mixing of the components without the necessity of driving the blade rod so the expenditure of power for the accomplishment of the mixing process is considerably reduced. Moreover, the mixed components are charged continuously in the mixing device so that a continuous process of mixing is ensured, which allows a considerable reduction in the dimensions of the mixing device.
Description of attached drawings
Figure 1 is a schematic illustration in semi-section of the mixing device.
Examples for particular realization
The mixing device consists of body 1 , monolithic or assembled construction. Basically, the body 1 can have various cross-sections. However the preferred shape is cylindrical because it allows for the best allocation of the remaining elements of the mixing device. The type of the material of the body 1 depends on the climatic conditions of exploitation of the mixing device and is determined by the working pressure, the limitations of the height of the liquid column and the source of compression so that it is no more than 0,25 MPa.
Segmented blades 2 are located in the working part of the cylindrical body 1 , at a certain angle α that is determined by the viscosity of the mixed components. Each blade 2 is rotated to the former at an angle, which allows screw-like movement and mixing of the components in one or a few revolutions along the length of the working part of the cylindrical body 1.
Blades 2 have a circular segment profile and are fixed on the cylindrical rod 3, fixed along the axis of the cylindrical body 1. The rod 3 is firmly fixed to the body 1.
Both ends of the cylindrical body 1 can be coned. On the top of body 1 an orifice 4, which charges one of the components (for example, oil), is fixed. Orifices 5 (one or more) are located in the cone part of the cylindrical body 1 at an angle of 45° to its axis.
The mixing device functions as follows:
The oil is charged at the input of the cylindrical body 1 through the orifice 4 and is mixed with the water and the overheated steam currents, charged through the orifices 5 located in the cone part of the cylindrical body at an angle of 45° to its axis.
Because of the design of the blades 2 and their mutual position to each other and to the rod 3 turbulization of the current is achieved which leads to the intensification of the process of mixing of the participation compounds.
The mixture of oil and water flows turbulently to the lower part of the mixing device along the channel formed by blades 2 and rod 3, from where the obtained mixture is discharged through orifice 6 at a high homogeny of mixing.
