Description

A kind of block forming vibrator based on chaotic vibration
Technical field
The present invention relates to a kind of vibrator, relate in particular to a kind of block forming vibrator based on chaotic vibration.
Background technology
Building block is that a kind of clay that do not use is done raw material, does not need the novel building of the low energy consumption that forms by a firing, wide purposes to build not structural material; Particularly utilize the industrial solid wastes such as gangue, cinder, mine tailings, slag, flyash to do the high-performance building block product that aggregate is made; to save soil, protection of the environment, utilize resource, save the energy etc. all tool be of great significance, be that the great Novel environment-protective energy-saving construction material project of development is all actively being widelyd popularize in countries in the world.Yet, because the fixed frequency of the raw-material diversity of building block and every kind of material is different, improves the block forming packing and become a great problem that various equivalent modifications is faced.
Manufacture out the building block product of high-performance, wide purposes, must rely on high-performance automatic forming machine of building blocks equipment, as brickmaking machine, coal making machine, cement pre-fabricated panel etc., and the vibration moulding technology, it is the core key technology of automatic forming machine of building blocks equipment, can not only determine and represent the technical performance level of block forming machinery equipment, and can directly determine and reflect the capability and performance result of building block product, and vibrator is plant equipment commonly used in the vibration moulding technology, and the oscillating mass of vibrator determines the quality of building block.At present, all there are following one or more shortcomings in the vibrator in China's block forming machinery equipment:
1, vibrator commonly used is the mechanical type inertia vibrator, although the structure of this vibrator is simple, but exciting force is less than normal, amplitude and the frequency ratio that shakes are more single, cause the block strength of producing low, of poor quality, although some advanced technology can realize amplitude modulation and frequency modulation function, but vibrator still can not be with two or more frequency work, therefore, existing vibrator does not catch up with the development rhythm of modern building block building, can not satisfy the demand for development of modern building block building.
2, existing vibrator is aspect technical regulation, due to the restriction that is subject to the aspects such as design philosophy, technical merit, comprehensively manufacturing ability, the control device of most vibrators all is in reduced levels, only have that only a few can realize shaking frequently, the step-less adjustment of amplitude and exciting force, the gently advanced technology regulation and control level requirement of moment conversion of shaking and shake by force, thereby restricted the fast lifting of China's building block product technical performance and quality level.
3, due to the restriction that is subjected to structural design, existing vibrator ubiquity vibration source drive point is few, the technological deficiencies such as the exciting force area of effective coverage is little cause the shake table area of block forming machinery equipment little, and the finished product packing that makes is little, error is large, yield rate is low.
This shows, prior art awaits further improving and improving.
