The invention relates to machines for mixing various viscous materials and can be used in bakery production for cooking arawu and test in the confectionery business for whipping creams and protein masses in the chemical and petrochemical industry to accelerate reactions when mixing reagents in construction and industry of construction materials for the preparation of mortars and concrete, pharmaceutical, paint, oil and other industries.

Known planetary mixer for viscous materials containing mounted on the frame the bowl with agitator and drive agitators, including the motor, planetary gear and drove with satellite [1].

However, in this mixer no vibration kneading body in the mixing process, which does not allow for intensive processing mixed environment and purification kneading of the body from the adhered materials, which overloaded the engine and distorted form of kneading of the body.

Closest to the present invention is a planetary mixer for viscous materials containing the engine installed in the housing kneading bodies, the actuator which is executed in the form of a gear mechanism and a planetary mechanism includes a Central gear, satellites and drove [2]. In oksanaspecial kneading bodies mounted on Fadilah two planetary gear mechanisms, satellites planetary mechanism is equipped with unbalanced loads, the drive of the mixer contains three engines, and the Central gear of each planetary mechanism is connected with a separate engine.

The disadvantages of this mixer are:

1. The complexity of the design due to the necessity of using three engines and two planetary gear mechanisms with an unbalanced satellites.

2. Excessive starting load on the engine from a reactive alternating dynamic torque generated by unbalanced loads satellites.

3. The lack of customization on the varying amplitude of the angular oscillation drove with kneading bodies.

4. Rotational movement of the kneading bodies around the Central axis of the carrier at a fixed trajectory in the form of a circle of constant radius that does not provide intensive treatment in the whole volume of mixed environment and reduces the quality and performance of the mixing process.

The purpose of the invention is to simplify the design, reduce the starting load on the engine, improving the quality and performance of the mixing process due to the adjustable vibration impacts on stir Wednesday when the planetary movement of the kneading bodies throughout the volume of the body.

This is due to the fact that in planetar the m mixer for viscous materials containing the engine installed in the housing kneading bodies, the actuator which is executed in the form of a gear mechanism and a planetary mechanism includes a Central gear, satellites and drove, kneading bodies mounted on satellites offset relative to the axes of the satellites and form together with the satellite nodes, balanced with respect to these axes, and the Central gear of the planetary mechanism movably connected to the frame via an elastic element made in the form of a flexible plate in the middle attached to the shaft of the Central gear, and all based on floaters, the distance from the Central axis of the mixer can be adjusted; in the form of a replacement spring kit, perceiving the alternating torque on the Central gear; in the form of coaxially with the Central gear torsion shaft.

In figure 1, 2 and 3 shows the circuit of a planetary mixer for viscous materials with the execution of the elastic element connecting Central planetary gear mechanism housing, in the form of a flexible plate in the middle attached to the shaft of the Central gear, and all based on floaters, the distance from the Central axis of the mixer can be adjusted (figure 1); in the form of a replacement spring kit, perceiving the alternating torque centralsouthern (2); in the form of coaxially with the Central gear torsion shaft (figure 3).

Planetary mixer for viscous materials (figure 1) contains installed in the housing 1 kneading bodies 2, the actuator which is executed in the form of a gear mechanism 3 and the planetary mechanism includes a Central gear 4, satellites 5 and led 6 driven by the engine 7. Kneading bodies 2 mounted on satellites 5 offset relative to the axes of the satellites and form together with the satellite nodes, balanced with respect to these axes by means of the counterweight 8, and the Central gear 4 of the planetary mechanism movably connected with the housing 1 through the elastic element 9.

Figure 1 shows an embodiment of the elastic element 9 in the form of a flexible plate in the middle attached to the shaft of the Central gear 4, and the ends rests on the slide 10, the distance from the Central axis of the mixer can be adjusted. Figure 2 shows an embodiment of the elastic element 9 in the form of a replacement spring kit, perceiving the alternating torque on the Central gear 4. Figure 3 shows an embodiment of the elastic element 9 in the form of coaxially with the Central gear 4 torsion of the shaft.

Planetary mixer for viscous materials is as follows.

When the rotation of the carrier 6 (Fig 1) from the engine 7 through puredata the economic mechanism 3 5 satellites with kneading bodies 2 do inside the housing 1 with a viscous mixing media complex non-circular motion; as a result of this kneading bodies 2 are moved in a viscous fluid with variable speed, taking into account the dependence of the forces of viscous resistance of the speed, leads to the appearance of an alternating torque on the satellite 5 and causes torsional vibrations of satellites with 5 fixed on them kneading bodies 2. Fluctuations in the absolute trajectory of kneading bodies 2 has a complex appearance. The oscillation amplitude of 5 satellites attached to them kneading bodies 2 can be adjusted by changing the stiffness of the elastic element 9, for example, moving the slider 10 relative to the housing 1, which allows you to set the mixer on the most optimal for your environment mode vibropressovanija.

Achieved in the proposed mixer positive effect consists in the following:

1. Simplifies the design of the mixer, as the heavy vibropressovannye throughout the volume of the viscous fluid occurs due to the use of only one motor and one planetary mechanism.

2. In the planetary mechanism through the use of satellites and kneading bodies, forming balanced with respect to the axes of the satellite nodes reduces the starting load on the engine and also reduces the load bearing satellites from the forces of inertia.

3. Improving the quality and productivity p is ocess mixing: (a) due to the possibility of tuning the elastic element of the planetary mixer at an optimum for a given viscous medium mode vibropressovanija; b) due to the complexity of the trajectory of the kneading bodies.
