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 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 drive motors, gear mechanism housing, which is installed inside a vertical impeller shaft with the drive of the rotation and the vibration exciter in the form of unbalanced planetary gears, and elastic elements set the go between the planet carrier of the planetary vibration exciter and gear mechanism, kneading bodies placed on the Central driven shaft of the transfer mechanism [2].

The disadvantages of this mixer are:

1. Only rotational motion of kneading of the body, which greatly reduces the quality of the finished mixture and the performance of the mixer; to get trudnosmyvaemye foamy confectionery composition is almost impossible.

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

3. The increased mass of the structure due to the presence of unbalanced loads and units designed for the higher load.

4. The complexity of the design due to the necessity of the use of two drive motors.

The purpose of the invention is to reduce the weight of the structure, reducing the starting load on the drive motor, the improvement of the quality and performance of the mixing process by targeted and isolated 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 a planetary mixer for viscous materials containing a driving motor, a casing located inside kneading bodies, elastic elements, gear and plan the tare mechanism, includes drove, the Central gear and installed it in engagement satellites with balances, which are connected with the satellites via elastic elements, which transmit torque, kneading bodies fixed eccentric balance sheets, forming with them balanced nodes. While satellites can be made of different diameters; an eccentric mounted on the balances kneading bodies can be mounted in pairs in antiphase; elastic elements on different satellites can be made of different hardness; gear can be made in the form of simple gear, top gear which is installed on the shaft of a drive motor and driven interlocked with the planet carrier of the planetary mechanism; gear can be made in the form of a planetary gear with two Central gears, one of which is installed on the shaft of a drive motor, and the other fixed to the body.

In figure 1, 2, 3 shows a diagram of the planetary mixer for viscous materials. Figure 1 shows an embodiment of the transfer mechanism in the form of simple gear, figure 2 in the form of a planetary gear. Figure 3 shows the installation of the satellites of different diameters and pairwise opposite phase installation kneading bodies on the balance sheets.

Planetary mixer for viscous materials (f is 1) comprises a drive motor 1, case 2, gear 3 in the form of a simple gear and a planetary gear mechanism that includes a carrier 4, the Central gear 5 and installed it in engagement satellites 6 with balance sheets 7, which are connected with satellites 6 through the elastic elements 8; kneading bodies 9, mounted eccentrically on the balance sheets 7. Kneading bodies 9 and balances 7 form nodes, balanced with respect to the axes of the satellites 6.

Figure 2 shows an embodiment of the transfer mechanism in the form of a planetary gear unit containing fixed to the body of the Central gear 10.

Figure 3 shows a section a-a (see figure 2), which shows the satellites 6 of different diameters and kneading bodies 9, mounted in pairs on the balances in antiphase (figure 3 diameters of 6 satellites and balances that form one node, shown symbolically the same).

Planetary mixer for viscous materials is as follows.

When the rotation of the carrier 4 from the engine 1 (1) 6 satellites with kneading bodies 9 do inside the housing 2 complex movement. While kneading bodies 9 are moved in a viscous fluid with variable speed that, due to the dependence of the forces of viscous resistance of the speed, leads to a variable point on the balance sheets 7 and causes torsional oscillation relative to the satellites 6. Execution will sosite the I with balanced satellites 6 different diameters provides different frequency processing of the mixture, and the installation of balances between 7 and 6 satellites elastic elements 8 different stiffness provides different amplitude kneading bodies 9.

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

1. Improving the quality of mixing of viscous materials: a) by targeted and isolated vibration impacts on mixed environment; b) due to the complexity of the trajectory of the kneading bodies; C) due to polyfrequent and with different amplitudes impact on mixed environment.

2. In the planetary mechanism through the use of balanced nodes, including satellite, balance with kneading body and an elastic element, reduces the starting load on the engine and also reduces the load bearing satellites from the action of inertia forces.

3. Reduced weight and cost planetary mixer through the use of a single drive motor, balanced satellites and less loaded nodes, as well as by reducing PM mass when they lock with the satellites performing a complicated movement.

SUBSTANCE: kneading and mixing machine has at least one rotating working device which is adapted for insertion into pan rotating around vertical axis. Locking device is provided on pan bottom. For discharging of mixed contents, locking device is caused to move in vertical plane to intermediate position and is further moved around horizontal axis within pan to discharging position. Rotation of locking device within pan for discharging of mixed contents allows discharge process to be intensified after kneading of mixture owing to the fact that locking device remaining in pan after rotation provides guiding device functions apart from other functions.
