Description

The present invention relates to a self-regulating, two-degree planetary mixer. The mixer can be used to mix liquids, solid particulates, and liquids and solid particulates. It is particularly suitable for mixing, kneading and homogenizing high viscosity, viscous, sticky materials or materials of different viscosity.
In practice, there are several types of mixers for difficult to mix materials. One of these is a multi-actuator mixer having a plurality of different agitator elements which can be operated together or independently. Such a mixer is described in patent HU 222 902. The present invention relates to a mixer, preferably a concrete mixer having a funnel-shaped mixing tank. An inner and outer agitator are coaxially disposed in the central axis of the mixing vessel. The internal agitator consists of an infinitely-driven auger. The external agitator also comprises infinitely variable actuator-driven paddles mounted on the agitator arm, where the paddles contact the surface of the agitator tank. The agitators are rotated alternately in the same and opposite directions. The mixer provides a rapid, intense mixing of the liquid and particulate materials with opposite and transverse mixing flows. A disadvantage of the invention is that it cannot adapt to the change in torque demand due to the change in viscosity of the mixed material. Increased resistance due to compaction of the mixed material can cause damage to the equipment. A further disadvantage of the device is that two motors are required for intensive movement.
Another type of mixer uses a planetary drive. Such a solution is described in U.S. Patent No. 4,697,929. The mixer drives two concentric drives at least two axes that can rotate independently at different speeds. The center wheel of the planetary gear is mounted on one axis and the planetary wheels are mounted on the other axes. There are agitator paddles in the center wheel axis and the planetary axes. The agitator of US 4,697,929 is formed by a planetary gear of freedom. In this case, the agitator blades can only rotate at the same speed, i.e. they cannot overcome the load changes due to the different density of the mixed material. Other drawbacks of the invention are the complex construction, the high cost of manufacture and the greater probability of failure.
It is an object of the present invention to provide a planetary agitator which is structurally simple and whose movement state is determined by the load torque conditions of the mixed material. That is, as the quality of the mixed material (viscosity, etc.) changes, the motion state of the agitator that moves the planet changes.
The object of the present invention is achieved by incorporating two self-regulating planetary gear units. The motion state of the two degrees of freedom planetary gear can be arbitrary, with the advantage that, for a given input speed, the agitating and rotary motion of the mixing elements can change in a self-regulating manner depending on the properties of the mixed material. The possibility of any movement state also includes that the mixing elements perform only progressive or only rotary movement. This circumstance ensures that certain malfunctions (bearing settling, tooth entanglement at the tooth fracture), foreign material impeding the movement of the agitator element, or knot formation of the mixed material do not cause malfunction, i.e. continuous operation. If, for any reason, the drive chain is interrupted, the drive system will be in a state of inability to transmit energy, resulting in an idle state and thus no breakage or other damage to the equipment. The presence of foreign matter in the mixed material and the formation of lumps can be detected by dynamic sensors.
The present invention is a self-regulating, two-degree planetary mixer comprising the following
- a housing,
- a central gear (1, 11, 21, 31, 41, 51, 71, 81, 91, 101, 111, 121), which is mounted in a manner allowing pivoting in the support housing (5) by means of a central shaft (7,17), optionally coupled to the transmission motor via a transmission or transmission and clutch,
- at least one planetary gear which is fixed to the planetary gear shaft in a torque-transmitting manner and which is coupled to the central gear,
- at least one agitator which is fixed to the planetary axle in a torque-transmitting manner,
- a bridge in which the at least one planetary axle and the central axis are supported in a manner allowing two degrees of freedom of movement of the agitators.
The agitator according to the invention also operates in the form of a planetary gear connected to a central gear, especially at slow speeds, for mixing dense or lumpy material. In most cases, it is preferable to use two or more planetary wheels where the planetary wheels are centrally symmetrical to the central axis and are connected to the central gear. In a preferred embodiment, the number of planetary wheels directly connected to the central gear is two. In a further preferred embodiment, the number of planetary wheels directly connected to the central gear is three.
The planetary wheels may be connected directly or via auxiliary planetary gear to the central gear. According to a preferred embodiment of the invention, at least one auxiliary planetary gear is arranged in relation to the planetary gear and the central gear. In a further preferred embodiment of the invention, two centrally symmetrical planetary wheels and two centrally symmetrical auxiliary planetary wheels and two planetary wheels are connected to a central gear. The resulting drive chain allows for a very thorough mixing of the mixed material in the mixing tank.
In a preferred, simple embodiment of the invention, a central gear is secured to the central axis in a torque-transmitting manner. In the case of more difficult mixing materials, two central gears may be attached to the central axis such that at least one planetary gear is connected to each of the central gears. The central gears can be either internal gears or external gears.
The agitator is fixed on the planetary axles and the auxiliary planetary axles in a torque-transmitting manner. According to a preferred embodiment of the invention, each planetary planetary shaft and each auxiliary planetary planetary axis are provided with mixing means. By selecting the number of mixing devices and their arrangement, a wide variety of materials in the apparatus can be effectively mixed. In the planetary mixer according to the invention, the shape and size of the mixing means are optional. Mixing means known and used in the art, such as a paddle mixer or a screw mixer, may be used. According to a preferred embodiment of the invention, the mixing means mounted on the planetary axles have the same shape and size. In a further preferred embodiment, the mixer has two planetary wheels, wherein the planetary wheel axes are fitted with a mixing device of different shape and / or size.
It may also be advantageous to have a mixing means fixed to the central axis of the central gear by means of a torque transducer. The agitator coupled to the central axis does not perform two degrees of freedom. Its role is in the good mixing of the material around the center of the mixing vessel.
The mixer according to the invention has a mixing container known per se into which the mixing means extend. According to a preferred embodiment of the invention, the mixing tank or mixing means are arranged such that the mixing means move along the inner surface of the mixing tank as they are rotating and moving. This design results in a better mixing of materials and a homogeneous mixture.
In order to prevent admixture of admixed material on the wall of the mixing vessel, the device may be provided with a release knife known per se. The release knife fits into the inner surface of the mixing vessel and passes along the surface to release material therefrom. According to a preferred embodiment of the invention, the release knife is connected to the bridge. According to a further preferred embodiment, the release knife is configured in an adjustable manner around its axis.
According to a further preferred embodiment of the invention, the bridge may be formed as a housing surrounding the central gear and planetary wheels from which the central axis and the planetary axes extend.

1a to 6b. Figures 3 to 5 show a kinetic diagram of various embodiments of a dual-freedom planetary mixer according to the invention. 1a to 5b. Figures 3 to 5 show three agitator devices centrally symmetrical to the central axis, where for simplicity and clarity only one agitator head is shown. As used herein, the term "agitator head" means a planetary wheel equipped with a agitator or a combination of a planetary wheel and an auxiliary planetary wheel having at least one agitator. 6a-6b. Figures 1 to 5 show four agitator devices arranged centrally symmetrically to the central axis.
According to the invention, the movement of the mixing means is provided by a planetary gear, which in the simplest case is shown in Fig. 1a. 1b and 1b. As shown in FIG. 6B, it consists of a central gear 1, planetary wheels 3 and a bridge 2. The central gear 1 is mounted on a central axis 7 in a torque-transmitting manner. The central axis 7 is mounted in a bearing housing 5. The central axis 7 is connected via a coupling motor (not shown) to the drive motor. The drive motor drives the central gear 1, if necessary, via a transmission or gearbox not shown in the drawing. The central gear 1 is connected to 3 planetary wheels. In this embodiment, three planetary wheels 3 (not shown) are connected to the central wheel 1 (not shown). The planetary wheels 3 are torque-wedged to the planetary planetary axes 8. The central axis 7 and the planetary wheel axes 8 are also connected by 2 bridges such that the axles in the 2 bridges are bearing. The planetary axes 8 have agitators 4 attached to the torque transducer and the central axle 7 has a central agitator 6 also secured by a torque transducer. The planetary mixer thus assembled has two degrees of freedom; the mixing means 4 make a rotation about the planetary axes 8, while their axis line moves along the bridge 2. According to the construction, the central agitator 6 mounted on the central axis 7 of the central gear 1 can only rotate. The agitator 4 may have a variety of motion states, such as planetary motion, that is to say, in addition to its axial movement, it also rotates about its own axis. The actual state of motion is determined by dynamic conditions, that is, a state of motion under which the external force system, that is, the propulsion system and the load force system, are in balance.
Assuming a lossless drive, given the driving torque Mi, the peripheral forces transmitted through the tooth connections between the central gear 1 and the planet gear 3 apply a load torque M3 to the planetary axes 8 and a load torque M2 to the bridge 2. These torques in stationary operation maintain an equilibrium with the external load torque acting on the mixing means 4, i.e. a constant state of motion is achieved at which the balance of the operating power system is achieved. Since the planetary motion state of the mixing head 4 can be arbitrary, any internal element can be stopped. This circumstance ensures that in the event of a malfunction (bearing loss, tooth fracture or foreign material entanglement) malfunctions and further consequential damage do not occur. this will allow continuous operation. And if the damage results in a break in the drive chain, the drive system moves into an inability to transmit energy, ie idling, thus protecting the unit from consequential damage.
According to the invention, the structure, geometry and kinematic parameters of the mixer can be very diverse. Examples of various embodiments are shown in Figures 2a to 6b. FIGS.

2a. and 2b. The embodiment shown in FIGS. 1 to 4 has an internal gear central gear 11 to which the planet gears 13 are engaged. The central axis 7 of the central gear 11 is mounted in the bearing housing 5 to allow pivoting. In the bridge 12, the central axis 7 and the planetary wheel axes 8 are supported. In this embodiment, the agitator is not fixed to the central axis 7, only the agitator means 4 are fixed on the planetary axles 8 in a torque-transmitting manner.
3a. and 3b. Figures 6 to 9 show an auxiliary planetary gear, wherein the outer gear central gear 21 is connected to the auxiliary planet 26 and the auxiliary planet 26 to the planetary wheels 23. The central axis 7, the planetary wheel axes 8 and the auxiliary planetary wheel axes 9 are mounted in the bridge 22. The agitator 4 is mounted on the planetary wheel 8.
4a. and 4b. Figures 3 to 5 show a central gear design with auxiliary planetary gear with internal gear. The central shaft 7 is provided with a central gear 31 having an internal gear. The central gear 31 engages with auxiliary planetary wheels 36 and the auxiliary planetary wheels 36 with planetary wheels 33. The central axis 7, the auxiliary planetary wheel 9 and the planetary wheel 8 are mounted in the bridge 32. For the sake of simplicity, only mixing means 4 fixed to the planetary wheel axis 8 are shown in this embodiment. Of course, the auxiliary planetary axes 9 may also be provided with mixing means 4 and a central mixing means 6 may be mounted on the central axis 7.
5a. and 5b. Figures 4 to 5 show a special arrangement of the helicopter wheel design. The outer gear central gear 41 engages with auxiliary planetary wheels 46 and auxiliary planetary wheels 46 with planetary wheels 43. The bridge 42 includes the central axis 7, the auxiliary planetary axles 9 and the planetary axle 8 bearings. The mixing means 4 are fixed to the planetary axles 8.
1a to 5b. The embodiments shown in Figs. In these cases, dynamic balancing must be ensured. Such designs may be required when mixing dense materials at slow speeds.
6a. 6b and 6b. Figs. 1a to 1b illustrate an embodiment which is in fact shown in Figs. 3a and 3b. 1 through 2. This mixer has four centrally symmetrical mixing heads. In the bearing housing 5 is mounted the central shaft 7 mounted on the outer shaft 51 central ♦ · 4 «
gear fixed. A central mixing means 6 is also mounted on the central axis 7 as shown. Central planetary gear 51 engages two planetary wheels 113 and two auxiliary planetary wheels 56. The auxiliary planetary wheels 56 engage with two further planetary wheels 53. In the bridge 52, the central axis 7, the auxiliary planetary wheel axes 9 and the planetary wheel axles 8 are supported in a pivotable manner. Mixing means 4 are connected to the planetary axles 8. In this embodiment, if the number of teeth of the auxiliary planetary planes 56 and the planetary planes 113 are chosen to be the same, a constant motion condition is created at the same input angular velocity at which the loading torques (resistive torques of the mixing heads) Of course, the torque portions of the two planetary and auxiliary planetary drive chains are distributed in proportion to the load torques of the different drive chains and appear in half of the same drive chain (if the two mixing heads are the same). From the kinetic sketch, it can be seen that the rotary motion state of the mixing means 4 connected to the planetary wheel axis 8 of the planetary wheels 53 and 113 creates an opposite state of flow (flow) of the mixed material, which may be favorable for mixing efficiency.
To explain the mixer torque conditions, see Fig. 1a. Figure 6a. Internal gear ratio (which is the quotient of the angular velocity of the central gear 1 and the planet gear 3 in the coordinate system linked to the bridge 2)
U13 = -Z3 / Zi, (1) where
U13 is the internal gear ratio of the drive, zi is the number of teeth on the central gear, z 3 is the number of teeth on the planetary gear.
By applying a constant torque of M-ι = 1 Nm to the central axis 7 of the central gear 1 rotating at a constant speed in stationary mode, to ensure static torque equilibrium 3 (neglecting tooth and bearing friction losses) on planets 3 ( )
Μ 3 = - Mi Ui 3 = -1 U13 = - u 13 [Nm] load torque and on bridge 2
M 2 = Mi (u 13 -1) = 1 (ui 3 -1) = u 13 -1 [Nm] load torque required.
If the number of three planet gears N (N = 2, 3, 4, ...), centrally beside symmetrical planetary gear accommodation and the same load conditions as a three planet wheels M 3 / M, the two bridges (by a three planet gears) M 2 / n load torque is working. Uneven load bearing cannot occur due to static uncertainty as the system has two degrees of freedom.

U 2 1.23 ~ Z 23 / Z 2 1, (4) where u 2 i, 23 is the internal gear ratio of the drive, z 2 ia is the number of teeth of the central gear, z 23 is the number of teeth of the planetary gear.
The internal transmission in this case has a positive sign, ie the rotation sense of the central gear 21 and the planet 23 in the coordinate system linked to the bridge 22 is the same, and the computational relations of M 2 i and M 22 , M 23 are also unchanged.

First
An important feature of the mixer is the torque ratio k = M21 / M23 = U21,23 - 1 / - U21.23 (5)
Equations (1) to (5) apply to any planetary system or auxiliary planetary system, where the drive is driven in the central axis of the central gear and the drive is in the axis of the planetary gear or the auxiliary planetary wheel. If the bridge is equipped with an adjustable angular separation knife, or if there is a mixing device on both the planetary and auxiliary planetary axles, the torques and torque conditions will change accordingly.
The construction of the mixer can be very diverse. Deciding what kind of structure, geometric gear (internal gear), or mixing device is required to perform a given mixing task optimally can be very complex and theoretically calculated, since load forces and torques are influenced by many factors, such as design and movement of mixing devices, properties of the mixed material, technical parameters of the mixer, etc. Therefore, experimental measurements are needed to determine the optimum gear parameters.
Figures 7 to 13 show various embodiments of a mixer according to the invention. However, the invention is not limited to the embodiments detailed below. Many other structural arrangements and combinations are contemplated within the scope of claim 1.
In addition to the simple construction of the mixer shown in Figure 7 in the front view and Figure 8 in the top view, it is particularly suitable for kneading the materials well to produce a homogeneous mixed material. The drive housing 5 has a central drive shaft 7 mounted on the drive. A central gear 71 with outer teeth is mounted on the central axis 7 in a torque-transmitting manner. Two planetary wheels 73, 123 of different sizes are connected to the central gear 71. The planetary wheels 73, 123 are mounted on planetary axles 8 in a torque-transmitting manner. In the bridge 72, the central axis 7 and the planetary wheel axes 8 are mounted in a pivotable manner. The agitators 4, 41 are fixed to the axles of the planetary wheels 73, 123. The mixing means 4, 41 in this embodiment are designed as a curved blade mixer. The size of the mixing means 4, 41 is different, and the larger size mixing means 4 is mounted on the axis 8 of the larger planetary wheel 73. The material to be mixed is contained in the mixing container 74 into which the mixing blades 4, 41 extend. The asymmetric selection of mixing blades results in a good mixing of the mixed material by extending the mixing means 4 beyond the center of the mixing container 74 and preventing the material from being left unmixed in the central area of the mixing container 74.
Figure 9 shows a centrally symmetrical mixer head mixer. In the bearing housing 5, two central gears 81, 111 of different sizes are mounted on a central shaft 7 bearing in a torque-transmitting manner. The central gear 81 has 83 planetary wheels and the central gear 111 has 133 planetary wheels. The mixing means 4 immersed in the mixing tank 84 are fixed to the planetary axes 8. In the symmetrical bridge 82, the central axis 7 and the planetary wheel axes 8 are supported.
Figure 10 shows a symmetrical arrangement of four stirring heads. Inside the bearing housing 5 is mounted a central shaft 7 bearing an inner gear central gear 91 which is connected to four identical planetary wheels 93. The central axis 7 and the planetary wheel axes 8 can be pivotally mounted in the bridge 92. The mixing means 4 extending into the mixing tank 94 are mounted on the planetary axes 8.
Figure 11 illustrates a further preferred embodiment of the invention. This embodiment is also symmetrical, with the bridge 102 being a closed housing. In the bearing housing 5 is mounted a central shaft 7 mounted on a central shaft 7, which is connected to two planetary gears 103 of the same size. A central agitator 6 is also attached to the central axis 7 in a torque-transmitting manner. Here, the central axis 7 and the planetary wheel axes 8 are also mounted in the bridge 102. The bridge 102 is a closed housing design that surrounds the central gear 101 and planetary wheels 103. Such a design of the bridge 102 provides the mixer with high mechanical strength while protecting the associated gears from contamination and splashing of the mixed material. Detaching blades 105 are attached to the bridge 102. The release blades 105 are disposed in the interior of the mixing tank 104 and are adjustably connected to the bridge 102 about their axis.
• · ·
Fig. 12 and Fig. 13 illustrate three agitator heads. The drive, i.e. the center gear 121 with the internal gear, is not driven through the central shaft 17 in this case. A drive gear 20 is attached to the central gear 121 which drives the agitator heads coupled to the drive gear 10. The mixing means 4 projecting into the mixing vessel 114 are mounted on the planetary wheel 18 of the planetary wheels 143. The planetary wheel axes 18 and the central axis 17 are supported in the bridge 112.
The mixer according to the invention is suitable for efficient, energy-efficient mixing of materials of various states, viscosities, adhesive properties. The advantage of the mixer is that it meets the torque requirements resulting from the change in viscosity of the mixed material. A further advantage of the apparatus is that since a given material quality always has a given mixing motion state, the quality of the mixed material can be deduced from the measurement of the bridge revolutions. There is thus no need for subsequent testing of the mixed material. Stirring can be stopped automatically once the bridge has reached the specified speed for the desired material quality. A further advantage of the mixer is that it is extremely efficient.
