Abstract
The invention discloses a composite stirring paddle, which relates to the technical field of stirring and mixing and comprises a paddle body and blades which are arranged along the radial direction of the paddle body, wherein the blades are in a concave arc shape, the concave surfaces of the blades face the advancing direction of the blades, openings are formed in the two radial ends of the blades, a fixedly-arranged mixing piece is arranged in the blades, and a flow passage which can enable liquid to do cross mixing movement in the mixing piece is arranged in the mixing piece. The invention has the advantages of good stirring and mixing effect, improved stirring and mixing speed and energy consumption saving.
Description
Technical Field
The invention relates to the technical field of stirring and mixing, in particular to a composite stirring paddle.
Background
At present, the radial stirring paddles have a single discharge instant direction, the movement direction of the flow field is mainly determined by the shape of the container and the internal structure, and the kinetic energy of the liquid discharge process is not fully utilized because the stirring paddles have a single discharge instant direction, so that the power consumption of the unit stirring operation is relatively large.
Disclosure of Invention
In order to overcome the defects of the background technology, the invention provides the composite stirring paddle which has good stirring and mixing effects, improves the stirring and mixing speed and saves energy consumption.
The invention adopts the technical scheme that: the utility model provides a compound stirring rake, its includes the oar body and follows the radial blade of installing of oar body, the blade is concave arc and its concave surface towards the blade direction of advance, the blade is equipped with the opening at radial both ends, be equipped with fixed mounting's hybrid in the blade, the hybrid is equipped with the runner that can let liquid do cross mixing motion in its inside.
The mixing piece adopts a spiral sheet combination, and the flow channel is a gap formed by interval and dislocation arrangement among the spiral sheets.
The mixing piece adopts metal filler, be equipped with a plurality of dislocation set and interconnect's supporting rib in the metal filler, the runner is the clearance between the supporting rib.
The number of the blades is 3-8.
The paddle body adopts a disc or a stay bar.
The beneficial effects of the invention are as follows: according to the technical scheme, the mixing piece is arranged on the concave arc-shaped blade in a built-in mode, the mixing piece is fixed on the concave arc-shaped blade through welding, bonding or bolts, and when the stirring paddle rotates, the kinetic energy of liquid discharged radially under the action of rotating centrifugation is fully utilized, so that the liquid can be subjected to cross mixing movement in the mixing piece on the blade when being discharged, the stirring and mixing effect is enhanced, the stirring and mixing speed is improved, and the energy consumption is saved.
