Abstract
The invention discloses an improved blade paddle stirrer which comprises a stirring shaft, a hub and paddles, and is characterized in that the front side edge of the working surface of the paddles is provided with a rectangular turbulence weir and is formed with rectangular guide holes which are uniformly distributed; and each rectangular guide hole is provided with a rectangular guide plate on the rear side edge of the paddles in the rotating direction. The blade paddle stirrer disclosed by the invention has the beneficial effects that one part of feed liquid flows to the back of the paddles by virtue of the guide holes under guide of the guide plates during the stirring operation, the axially flowing feed liquid forms an impact on the back of the paddles, the turbulence degree of the feed liquid is enhanced, the feed liquid can be well circulated and mixed, and the stirring efficiency and uniformity are improved; and moreover, due to the turbulence weir, uneven wear of solid particles in the feed liquid on the blades can be effectively avoided, the service life of the stirrer is guaranteed, and the economical efficiency of equipment is improved.
Description
Technical field
The present invention relates to a kind of agitator for reactor, the hinge paddle type stirrer of a kind of improvement specifically, belong to chemical industry mix and blend apparatus field.
Background technology
Hinge paddle type stirrer, its structure is simple, easy to manufacture, and generally its blade band steel is made, and by welding or be fixed by bolts on wheel hub, the number of blade has 2,3 or 4.Because it can meet general stirring requirement, therefore it is one widely used agitator in mechanical agitation type reactor.But the main deficiency existing for the agitator of this pattern is: the liquid stream mainly producing direction of rotation during stirring, and the scope of axial flow is little, therefore, need larger axis to stream, material is fully circulated and mix stirring operation operating mode time this pattern agitator be just not suitable for; In addition, when having a solid particle in the material be stirred, blade can produce uneven wear phenomenon sometimes, and this just makes shorten the service life of hinge paddle type stirrer.
Summary of the invention
The present invention is a kind of hinge paddle type stirrer of improvement, and it can overcome above-mentioned deficiency, has good whipping performance and enough service life, maintains again the advantages such as structure is simple, easy to manufacture and easy to maintenance simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A hinge paddle type stirrer for improvement, is made up of shaft, wheel hub and blade, blade can adopt be welded to connect also can with boltsly be arranged on wheel hub, wheel hub adopt key be mounted on shaft; It is characterized in that: the working surface front side edge edge in a rotational direction of described blade is provided with flow-disturbing weir, this flow-disturbing weir is a rectangular slab, and the thickness value on flow-disturbing weir is equal with the thickness value of blade, the length value on flow-disturbing weir is equal with the length value of blade, the height number on flow-disturbing weir is equal with the thickness value of blade; Described blade offers equally distributed rectangular guiding hole, each rectangular guiding hole back side edge is in a rotational direction along being provided with rectangular guiding plate, this rectangular guiding plate is positioned on the working surface of blade, the thickness value of rectangular guiding plate is equal with the thickness value of blade, the shape in the shape of rectangular guiding plate and size and rectangular guiding hole and size corresponding identical; The percent opening in that described blade is offered, equally distributed rectangular guiding hole is 20%-25%.
The present invention has following beneficial effect:
When stirring operation carries out, along with the rotation of propeller-blade, part feed liquid flows to the blade back side by pod apertures under the guiding function of deflector, and this part feed liquid flowed out from pod apertures flows substantially vertically, and feed liquid can be made better to be circulated and mix; The feed liquid of this part axial flow is formed the feed liquid at the blade back side and impacts simultaneously, because this enhancing the turbulent extent of feed liquid, improves efficiency and the uniformity of stirring.In addition, the existence on flow-disturbing weir can avoid the uneven wear that in feed liquid, solid particle produces blade effectively, ensure that the service life of agitator and improves operating efficiency, thus accomplishing economy.

Accompanying drawing 2 is that the axle on blade partial duty surface of the present invention measures intention;
Accompanying drawing 3 is that blade B-B position of the present invention rotates the sectional schematic diagram drawn;
Accompanying drawing 4 is schematic diagrames that the present invention applies in a kettle..
In figure: 1-shaft, 2-wheel hub, 3-blade, 4-flow-disturbing weir, 5-rectangular guiding hole, 6-rectangular guiding plate.
Detailed description of the invention
Now by accompanying drawing, more detailed explanation is carried out to the present invention.Above-mentioned accompanying drawing is all schematic diagrames of simple character, and therefore shown by it is only key element related to the present invention, for stating basic structure of the present invention and principle.
As illustrated in the accompanying drawings from 1 to 3, the present invention is made up of shaft 1, wheel hub 2 and blade 3, and blade 3 and wheel hub 2 can adopt that weld also can be with bolts, and shaft 1 adopts key to be connected with wheel hub 2 and is aided with finger setting.The working surface front side edge edge in a rotational direction of described blade 3 is provided with flow-disturbing weir 4, the geometry on this flow-disturbing weir is long and narrow rectangle, and the thickness on flow-disturbing weir and length are equal with the thickness of blade with the thickness of blade and length correspondent equal, its height respectively; Blade 3 offers equally distributed rectangular guiding hole 5, each rectangular guiding hole back side edge is in a rotational direction along being provided with rectangular guiding plate 6, this rectangular guiding plate is positioned on the working surface of blade, the thickness of deflector is equal with the thickness of blade, the shape in the shape of deflector and size and rectangular guiding hole and size corresponding identical; On above-mentioned blade, the percent opening in equally distributed rectangular guiding hole is 20%-25%; This rectangular guiding hole can be slot, also can be square hole.
When stirring operation carries out, the shaft rotated drives the material in the blade stirring reactor on wheel hub, at this moment the part feed liquid on blade working face will flow to the blade back side by pod apertures, and due to blade working face deflector guiding function this part from pod apertures flow out feed liquid substantially flow vertically, so just make stirring operation add axial stream, feed liquid can be made better to be circulated and mix; The feed liquid of this part axial flow forms side knock effect to the feed liquid at the blade back side simultaneously, because this enhancing the turbulent extent of feed liquid, improves efficiency and the uniformity of stirring.In addition, because the front side edge in blade direction of rotation is along being provided with flow-disturbing weir, therefore efficiently avoid the uneven wear that in feed liquid, solid particle produces blade, ensure that the service life of agitator and improve operating efficiency, thus accomplishing economy.Accompanying drawing 4 is situations that the present invention applies in a kettle..
