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 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 arranged at two radial ends of the blades, a fixedly arranged mixing piece is arranged in each blade, and each mixing piece is provided with a flow channel which can enable liquid to do cross mixing motion 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 direction of various radial stirring paddles is single at the moment of discharge, the moving direction of a flow field is mainly determined by the shape of a container and the structure of an internal part, and the kinetic energy of the liquid discharge process is not fully utilized due to the single direction of the stirring paddles at the moment of discharge, so that the power consumption of unit stirring operation is relatively large.
Disclosure of Invention
In order to overcome the defects of the background art, 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 technical scheme adopted by the invention is as follows: the composite stirring paddle comprises a paddle body and blades 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 mixing part is fixedly arranged in the blades, and the mixing part is provided with a flow channel which can enable liquid to do cross mixing motion in the mixing part.
The mixing part adopts the combination of spiral pieces, and the runner is the clearance that interval and dislocation set formed between the spiral pieces.
The mixing part adopts metal packing, a plurality of staggered and interconnected support ribs are arranged in the metal packing, and the flow channel is a gap between the support ribs.
The number of the blades is 3-8.
The paddle body adopts a disc or a supporting rod.
The invention has the beneficial effects that: this technical scheme embeds the mixing member on concave arc blade, and the mixing member is with welding, bonding or bolt fastening on concave arc blade, and when the rotatory operation of stirring rake, make full use of liquid radial exhaust kinetic energy under rotatory centrifugal action, make liquid make cross hybrid motion in the mixing member on the blade when the exhaust, strengthened stirring mixing effect, improve stirring mixing rate, practice thrift the energy consumption.
Drawings
Fig. 1 is a schematic structural diagram of a composite stirring paddle according to an embodiment of the invention.
FIG. 2 is a side view of a compound paddle.
Detailed Description
The embodiments of the invention will be further described with reference to the accompanying drawings in which:
as shown in the figures, the composite stirring paddle comprises a paddle body 1 and blades 2 arranged along the radial direction of the paddle body 1, wherein the blades 2 are in a concave arc shape, the concave surfaces of the blades face the advancing direction of the blades 2, openings are formed at the two radial ends of the blades 2, a fixedly arranged mixing piece is arranged in each blade 2, and each mixing piece is provided with a flow channel which can enable liquid to do cross mixing motion in the mixing piece; this technical scheme embeds the mixing member on concave arc blade, and the mixing member is with welding, bonding or bolt fastening on concave arc blade, and when the rotatory operation of stirring rake, make full use of liquid radial exhaust kinetic energy under rotatory centrifugal action, make liquid make cross hybrid motion in the mixing member on the blade when the exhaust, strengthened stirring mixing effect, improve stirring mixing rate, practice thrift the energy consumption.
The mixing element has two embodiments in this solution,
the first embodiment is as follows: the mixing part adopts the combination of flight 3, the runner is interval and dislocation set and the clearance that forms between the flight 3, and liquid gets into the mixing part, can flow along the helicoid of flight, because each flight dislocation set to make liquid make cross mixing motion.
Example two: the mixed part adopts metal packing (not shown), a plurality of support ribs which are arranged in a staggered mode and connected with each other are arranged in the metal packing, the flow channel is a gap between the support ribs, liquid enters the mixed part and can flow between the support ribs to pass through, and the liquid is blocked by the support ribs to be subjected to cross mixing motion.
The number of the blades 2 is 3-8.
The paddle body 1 adopts a disc or a supporting rod.
