Spiral agitator is a common mixing equipment widely used in liquid mixing,dissolution,dispersion,reaction and other processes in industries such as chemical,pharmaceutical,food,and environmental protection.The basic structure mainly includes the following parts:
1、Stirring blade(spiral blade)
The stirring blade,also known as the helical blade,is the core working component of a helical stirrer.Its shape usually presents a spiral shape,which can effectively generate shear and extrusion forces during the stirring process,thereby promoting the mixing,dissolution,or dispersion of materials.The rotation of the spiral blades of the spiral agitator lifts the material upwards from the bottom of the container,achieving comprehensive mixing of the material.The material,shape,and size of the blades will be selected according to specific mixing requirements and material characteristics to ensure the best mixing effect.
2、Mixing shaft
The mixing shaft is a key component that connects the mixing blade and the power source(such as the motor).It is responsible for transmitting power,allowing the stirring blade to rotate inside the container.The material and diameter of the mixing shaft of the spiral agitator should be determined based on the weight,viscosity,and required mixing force of the mixed material to ensure sufficient strength and rigidity.At the same time,the design of the mixing shaft also needs to consider the connection method with the mixing blade to ensure a firm fit between the two.
3、Motor and reducer
The motor is the power source of the spiral agitator,providing the necessary power for stirring.The reducer is used to reduce the speed of the motor and increase the torque to meet the actual needs during the mixing process.The selection of motors and reducers needs to consider factors such as the power,speed,and working environment of the mixer to ensure the stable operation of the entire mixing system.
4、Supporting device
The support device is used to fix and support components such as the mixing shaft,motor,and reducer,ensuring the stability and safety of the entire spiral agitator.It is usually composed of components such as brackets and bearing seats,which can withstand various forces and vibrations generated during the mixing process.The design of the supporting device needs to take into account the overall structure and working environment of the mixer to ensure its sufficient strength and stability.
In summary,the basic structure of a spiral stirrer includes stirring blades(spiral blades),stirring shaft,motor and reducer,and supporting device.These components work together to achieve efficient and stable operation of the spiral agitator.In the process of selection and use,it is necessary to make reasonable choices and configurations based on specific mixing requirements and material characteristics to ensure the best mixing effect and service life.
