A kind of speed change paddleTechnical field
The utility model relates to field of chemical equipment, particularly relates to a kind of speed change paddle.
Background technology
Conventional solid-liquid mixed method is generally added to respectively in agitator by two kinds of materials, and the method then stirred by mechanical agitation or bubbling is mixed.For the particle that granularity is larger or heavier, very easily there is " deposition " phenomenon when mixing with liquid.
Solid particle mixes with liquid, mixes and liquid gas mixes different from liquid liquid, because solid particle self has its weight, is easily deposited on the bottom of reactor.Such as, more common iron powder reducing reaction, due to iron powder weight, is easily deposited at the bottom of still, is unfavorable for stirring.If use common paddle to stir, the reaction time will be made to increase, energy consumption strengthens, and affects reaction effect.There is provided one to be suitable for mixing solids, the paddle making solid particle and liquid repeat to contact is most important.
Utility model content
Utility model object: technical problem to be solved in the utility model is to provide a kind of paddle being applicable to solid particle and mixing with liquid, and this paddle has the features such as structure is simple, mixing effect is good.
Technical scheme: the utility model provides a kind of speed change paddle, by the change of rotary electric machine speed, causes the difference of centrifugal force, thus gravitation ball can be moved up and down in the process stirred, and avoids the deposition of solid particle.
The utility model comprises shaft, paddle and rotary electric machine, it is characterized in that paddle is arranged at stirring the tip of the axis; The top of shaft 1 is provided with crossbeam, and crossbeam is provided with turning cylinder, connects gravitation ball by turning cylinder.Described gravitation ball is two, and is symmetrical arranged.
Described paddle is anchor formula paddle.
Described rotary electric machine is variable speed electric motors, particularly.Time static, due to gravity, gravitation ball is positioned at extreme lower position, and when rotated, due to centrifugal force, gravitation ball moves by position, and when rotary speed is the fastest, gravitation ball can reach the extreme higher position that it can reach.By the change of rotary speed, gravitation ball can be driven to move up and down.
Beneficial effect: technique scheme is provided with gravitation ball from different being of common paddle, and makes it move up and down by the change of rotary speed, thus avoids the phenomenon of solids particles precipitate and container bottom.It is good that the utility model has mixing effect, advantages of simple structure and simple.

detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.See Fig. 1, the utility model comprises shaft 1, paddle 5 and rotary electric machine 6, it is characterized in that paddle 5 is arranged at the end of shaft 1; The top of shaft 1 is provided with crossbeam 2, and crossbeam 2 is provided with turning cylinder 3, connects gravitation ball 4 by turning cylinder 3.Described gravitation ball 4 is set to two, and is symmetrical arranged.
Described paddle 5 is anchor formula paddle.
Described rotary electric machine 6 is variable speed electric motors, particularly.Time static, due to gravity, gravitation ball is positioned at extreme lower position, and when rotated, due to centrifugal force, gravitation ball moves by position, and when rotary speed is the fastest, gravitation ball can reach the extreme higher position that it can reach.By the change of rotary speed, gravitation ball can be driven to move up and down.
The utility model is provided with gravitation ball from different being of common paddle, and makes it move up and down by the change of rotary speed, thus avoids solids particles precipitate in the phenomenon of container bottom.It is good that the utility model has mixing effect, advantages of simple structure and simple.
