Description
Technical Field
The invention belongs to the technical field of raw material mixing, and relates to a three-degree-of-freedom motor-driven mixing device for mixing raw materials.
Background
The excellent effect of mixing materials by utilizing the vibration with high acceleration is gradually recognized in the industry. In order to obtain vibration with large acceleration, it is a preferable way to design a reasonable resonance structure. However, the vibration with large acceleration puts high requirements on the stable operation of the system, and not only the stability of the system itself but also the minimum transmission of the vibration to the outside are ensured, so the operation stability of the resonant structure of the system is also considered. On the other hand, the conventional resonant machine tends to increase the weight of the equipment rack to reduce the vibration intensity of the equipment rack in order to provide the stability of the system, so as to reduce the influence of the equipment on the surrounding environment, and therefore has the disadvantage of being "heavy".
Disclosure of Invention
The invention aims to provide a three-degree-of-freedom electromagnetic driving mixing device, which realizes the stable operation of large-acceleration vibration equipment by adopting a mode of offsetting, vibration isolation and vibration reduction and energy absorption and simultaneously reduces the weight of the equipment.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a three-degree-of-freedom electromagnetic driving mixing device comprises a rack, a first elastic suspension, a first vibrator, a second elastic suspension, a second vibrator, a third elastic suspension, a third vibrator, a mixing container, a fourth elastic suspension, a motor assembly and a damper.
The first vibrator is connected to the rack through an elastic suspension connection; the second vibrator is connected to the first vibrator through a second elastic suspension; the third vibrator is connected to the second vibrator through a third elastic suspension and is connected to the first vibrator through a fourth elastic suspension; the mixing container is fixed on the third vibrator; the motor assembly is 2 or 4 vibration motors or servo vibration motors and is fixed on the second vibrator; the damper is a particle damper or a liquid damper and is fixed on the first vibrator.
The mass and rigidity parameters of the elastic suspension I, the elastic suspension II, the elastic suspension III, the vibrator III, the mixing container, the elastic suspension IV, the motor assembly and the damper meet the condition that the third-order resonance frequency of the system is 50-70Hz, the phase difference between the vibrator II and the vibrator three is 180 degrees in a mode vibration mode, the ratio of the vibration displacement of the vibrator II to the vibration displacement of the vibrator III is equal to the ratio of the rigidity of the elastic suspension IV to the rigidity of the elastic suspension II and is 0.02-0.5, the vibration displacement of the vibrator III is effectively amplified, and therefore the vibration acceleration of the mixing container is amplified, the displacement of the vibrator II is smaller than that of the vibrator III, and the self energy consumption of the system is reduced; when the operating frequency of the motor assembly is the same as the third-order resonance frequency of the system, the system works in a third-order resonance mode, the vibration direction of the second vibrator is opposite to that of the third vibrator, and the acting force transmitted to the first vibrator is equal to the rigidity of the second vibrator in vibration displacement X elastic suspension and the rigidity of the third vibrator in vibration displacement X elastic suspension is equal to 0. The rigidity of the elastic suspension I meets the requirement that the first-order resonance frequency of the system is 5-20Hz, and the vibration of the oscillator I is further isolated from 50-70 Hz; the damper is fixed on the first vibrator, and further performs vibration reduction and energy absorption on the first vibrator, so that the vibration of the system is almost completely isolated from the external environment.
Compared with the prior art, the method has the following advantages:
1. the combined mode of offsetting, vibration isolation and vibration reduction and energy absorption isolates the high-acceleration vibration from the outside, and the stable operation of the system is ensured.
2. The effective isolation of vibration has effectively reduced the weight of frame compared traditional resonance machinery.
3. Simple structure, reduced equipment weight and cost.
