Abstract

The invention belongs to the technical field of stirring equipment and relates to a frame-type stirring paddle. The frame-type stirring paddle comprises a first hub and a second hub which are arrangedcoaxially, a plurality of horizontal blades are arranged on the circumferential surface of the first hub in an evenly distributed mode, the outer end of each horizontal blade is fixedly connected with a curved-edge vertical blade, and the lower parts of all the curved-edge vertical blades are fixedly connected with the circumferential surface of the second hub; and the blade faces of the horizontal blades and the axis of the first hub are arranged obliquely, and the surface of each curved-edge vertical blade is a curved surface. The stirring paddle can generate a circumferential flow and meanwhile can generate a high axial flow, the requirements for heat transfer and mixing uniformity of a whole tank are better meet, and an impeller with the efficient mixing performance being maintained within the wide viscosity range can be better met, so that the impeller is suitable for the processes of mixing, heat transfer, solid-liquid suspension, reaction, crystallization and the like of liquidwith various viscosity.

Description

technical field [0001] The invention belongs to the technical field of stirring equipment, and relates to a frame-type stirring paddle. Background technique [0002] The ratio of the diameter of the impeller blade to the diameter of the tank of the frame-type stirring paddle is large. When used in low-viscosity liquids, the ratio of blade diameter to tank diameter of the anchor impeller is 0.7-0.9, for high-viscosity liquids it is 0.8-0.95, and the speed is usually 10-50r / min. Frame type agitators usually operate at low speeds. Existing frame type agitators do not generate large shear force when stirring low-viscosity liquids. Dominant, does not have good mixing uniformity. Contents of the invention [0003] In view of the above problems, the present invention provides a frame-type stirring paddle, which can not only generate circumferential flow, but also generate higher axial flow, and better meet the requirements of heat transfer and mixing uniformity of the entire ta...
