Description

Technical Field

[0001] The invention relates to the technical field of stirring equipment, and in particular to a variable speed and direction rotating stirring device and a working method. Background Art

[0002] Mixing equipment is a typical process equipment in the chemical industry, and plays an important role in completing mixing operations. Mixing equipment can use a stirrer to mechanically mix media in the form of gas-liquid, liquid-liquid, solid-liquid, etc., or promote reactions between substances through stirring.

[0003] At present, most of the stirring equipment is limited by the structure of the transmission device. The stirrer mostly adopts unidirectional rotation. The stirring medium is easy to form a relatively stable flow field, and there will be a mixing isolation zone with poor fluidity and unfavorable for material mixing, so the mixing effect is poor; it is particularly obvious when stirring a medium with high viscosity or when there are restrictions on the stirring speed. The material mixing degree can be improved by alternating forward and reverse rotation in both directions. This can be achieved by adjusting the forward and reverse output of the drive mechanism, but the frequent and long-term alternating operation of forward and reverse rotation requires the drive mechanism to start and stop frequently to change the rotation direction, which puts a large load on the drive mechanism; there is currently a scheme that uses a transmission mechanism to convert unidirectional rotation into bidirectional alternating rotation, but its speed adjustment still depends on the adjustment of the drive mechanism, which makes it difficult for the drive mechanism to maintain a stable working state, and the speed fluctuation may exceed the normal working range of the drive mechanism, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and to provide a variable speed and direction rotating stirring device and a working method, in which power is transmitted through a multi-stage planetary reducer, and a clutch is configured for at least one stage of the planetary reducer to adjust the state of the wheel frame. When adjusting the state of the wheel frame, its transmission ratio can be quickly adjusted to meet the stirring speed requirement of the stirring component, and the alternating direction rotation requirement of the stirring component can be achieved through time-sharing engagement.

The transmission mechanism includes an output shaft with an output gear and two transmission gears rotating in opposite directions. The transmission gear is connected to the output end of the multi-stage planetary reducer. The two transmission gears are meshed with the output gear in a time-sharing manner to drive the output shaft to drive the stirring assembly to rotate alternately and in different directions.

[0007] Furthermore, the transmission assembly is installed on a bracket, and a brake is provided at a position of the bracket corresponding to the clutch, and the brake and the clutch jointly control the state of the wheel frame.

[0012] Furthermore, the stirring assembly includes a stirring tank and a stirrer, one end of the stirrer is connected to the output shaft, and the other end passes through the wall of the stirring tank and extends to the internal cavity of the stirring tank.

[0013] Furthermore, the mixing tank comprises an upper head of a cylinder, a cylinder section and a lower head of a cylinder which are connected in sequence, and a feeding pipe, a liquid level meter and a discharge pipe are arranged on the mixing tank.

[0014] The second object of the present invention is to provide a working method of the variable speed and variable direction rotating stirring device as described in the first object, comprising:

[0017] Adjust the clutch state so that the wheel carrier rotates with the sun gear, the sun gear of the reducer drives the ring gear to rotate through the planetary gear, and the ring gear drives the lower planetary reducer to move, so that the output shaft rotates at the second speed;

[0018] The two transmission gears mesh with the output gear in a time-sharing manner to alternately drive the output shaft, thereby driving the stirring component to rotate alternately in a changing direction.

[0019] Furthermore, a clutch is configured for a plurality of planetary reducers, and the rotation speed of the output shaft is changed by adjusting the clutch states of different planetary reducers.
