Stirrer with high stirring strength and high shearing force

Abstract

The invention discloses a stirrer with high stirring strength and high shearing force. The stirrer comprises a barrel, a permanent magnetic direct-drive motor, an equipped variable-frequency speed adjuster, a shearing force stirring paddle, a barrel internal shearing force guide plate, a barrel top anti-splashing baffle plate, a fixed support, a feeding port and a discharging port. Compared with the existing stirring device, the stirring paddle, the guide plate and the guide plate with strong shear force and the permanent magnetic direct-drive motor with large torque are simultaneously utilized, so that the stirrer has the advantages of high stirring strength and strong shear force; meanwhile, the energy consumption and repairing cost of the stirring equipment can be reduced.

Description

technical field [0001] The invention relates to a high stirring intensity and high shear force stirrer. Background technique [0002] Existing stirring devices are generally driven by a motor through a belt drive or a gear set. The mechanical transmission structure of this type of stirring device is complex, and there are many additional equipment. At the same time, the energy consumption of the equipment is increased and the efficiency of the system is reduced. What is more prominent is that the torque of the ordinary motor is low, and it cannot drive the stirring device to stir the material with relatively high viscosity, which requires strong stirring and strong shearing force, or the ideal stirring effect cannot be achieved. In addition, most of the stirring devices cannot adjust the stirring torque and rotational speed, resulting in the loss of equipment idling and the waste of energy consumption.

Problems solved by technology

[0002] Existing stirring devices are generally conveyed by electric motors through belt transmission or gear sets. The mechanical transmission structure of this type of stirring device is complex, and there are many additional equipment. At the same time, the energy consumption of the equipment is increased and the efficiency of the system is also reduced.

What is more prominent is that the torque of the ordinary motor is low, and it cannot drive the stirring device to stir the material with relatively high viscosity, strong stirring and strong shearing force, or the ideal stirring effect cannot be achieved.

In addition, most of the stirring devices cannot adjust the stirring torque and speed, resulting in the loss of equipment idling and the waste of energy consumption

In order to enhance the shear force of stirring, the methods currently used are generally by increasing the height-to-diameter ratio of the agitator, selecting a stirring impeller such as a sawtooth blade stirring impeller that can provide strong shearing force, and increasing the speed of the agitator, etc. The main purpose of the measures is to provide more and stronger circulating flow, but the height-to-diameter ratio and the shear surface of the blade edge have certain restrictions. Increasing the height-to-diameter ratio can increase the shear force intensity, but at the same time, the diameter of the blade needs to increase with the diameter of the cylinder. The diameter of the body decreases, so the shear force intensity provided by the blade will decrease; on the contrary, if the diameter of the blade is increased, the shear force intensity provided by the blade will increase, but it will cause a decrease in the cylinder's aspect ratio, and finally the overall shear force will increase. The increase in strength is very limited
