Abstract
The utility model relates to a paddle mounting angle adjustable structure which is capable of effectively solving the problem of paddle angle adjustment, meeting the stirring requirements of material parameters changed in a certain range, improving the using efficiency of stirrers and lowering the production cost. The paddle mounting angle adjustable structure adopts the technical scheme that the paddle mounting angle adjustable structure comprises paddles, paddle bottom plates, pressing plates and stirring shafts, wherein paddle wheel hubs are arranged on the stirring shafts, the paddle roots of the stirring paddles are welded together with the paddle bottom plates, and the pressing plates are fixed in the paddle wheel hubs, so that a mounting angle adjusting structure of the stirring paddles rotating in the paddle wheel hubs clockwise or anticlockwise is formed, therefore, the adjustability of paddle mounting angles is realized. The paddle mounting angle adjustable structure is convenient to process, mount, dismount and use; and the paddle angles can be adjusted, the use efficiency of stirrers is improved, and good economic and social benefits are achieved.
Description
Technical field
The utility model relates to the propeller-blade structure, particularly a kind of wing setting angle degree adjustable structure.
Background technology
Present propeller-blade, particularly the CBY blade is widely used in industries such as metallurgy, chemical industry, medicine, the field that be used for, the mixing of low-viscosity fluid, extraction, emulsification, solid suspends dissolving.Blade adopts bolt to connect with the journal stirrup that is connected through being welded on the shaft of shaft.For the mixing plant that has put into production use, in general agitator can only be directed against this kind material, with fixed rotating speed, use under the angle in fixed installation.When parameter of materials changes within the specific limits to some extent; Former agitator possibly just satisfy not the stirring requirement; Need to design again, if new departure adjustment is little, in the time of only need regulating stirring intensity by the size of blade angle according to new argument; Former welding manner has just influenced the enforcement of this scheme, thereby has influenced the service efficiency of former blade.This requires to reduce production costs, improve the product benefit to present social economy high speed development and has brought very big influence; So how to develop a kind of the need and makes again, satisfy the frame mode that has the parameter of materials demand now and become the technical issues that need to address through changing former blade angle.
Summary of the invention
To above-mentioned situation; For overcoming the prior art defective; The purpose of the utility model just provides a kind of novel wing setting angle degree adjustable structure, can effectively solve the adjusting problem of blade angle, the stirring demand when satisfying parameter of materials and changing within the specific limits; Improve the agitator service efficiency, reduce production costs.
The technical scheme that the utility model solves is; Comprise blade, blade base plate, pressing plate and shaft; The blade wheel hub is housed on the shaft, and the blade root of stirrer paddle and blade base plate weld together, and are fixed in the blade wheel hub by pressing plate; Constitute stirrer paddle in the blade wheel hub clockwise or the structure of the adjusting setting angle that rotates counterclockwise, realize the controllability of wing setting angle degree.
The frame mode of the utility model is convenient to installation and processing, adorns, tears open conveniently, and is easy to use; The blade angle can be regulated, and has improved the service efficiency of agitator, has good economic and social benefit.
Description of drawings
Fig. 1 is the structural front view of the utility model.
Fig. 2 looks part sectioned view for the left side of the utility model Fig. 1.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
By Fig. 1, shown in 2; The utility model comprises blade, blade base plate, pressing plate and shaft; Blade wheel hub 2 is housed on the shaft 1, and the blade root of stirrer paddle 7 and blade base plate 3 weld together, and are fixed in the blade wheel hub 2 by pressing plate 4; Constitute stirrer paddle in blade wheel hub 2 clockwise or the structure of the adjusting setting angle that rotates counterclockwise, realize the controllability of wing setting angle degree.
For easy to maintenance and assurance result of use, described pressing plate 4 is fixed on the blade wheel hub 2 by bolt 5 and spring shim 6; Described stirrer paddle 7 is the CBY blade, is that straight leaf, curved leaf, oblique leaf etc. are any type of a kind of.
The utility model is in practical implementation, and the blade wheel hub is contained on the shaft perisporium, utilizes key and is bolted to stirrer paddle and the welding of blade base plate on the shaft; To weld good blade base plate then and pack in the wheel hub, and cover pressing plate, and use bolt, this structure has just realized the controllability of wing setting angle degree.
The utility model basic principle is following: the power P=N of agitator
pρ N
3d
5, N
p=KRe
DFr
qF (d/D, b/D, H/D, θ ... ..), in the formula: ρ material density, N speed of agitator, d paddle diameter, b blade width, D tank diameter, K equation coefficient, θ stirrer paddle setting angle.In general, when blade angle θ diminishes, N
pReduce the also corresponding reduction of power P.When parameter of materials changes; For the mixing plant that has come into operation; Can be constant change the intensity of agitator under the situation of (being that power P, rotational speed N, oar footpath d remain unchanged) through adjustment CBY blade angle in the power allowed band, reach new stirring requirement at motor, constant, the former agitator of reductor.Stirring intensity becomes big when angle increases, and stirring intensity weakened when angle reduced, and can adjust the setting angle θ of blade as required, satisfies the demand of existing parameter of materials power of agitator, thereby improves the service efficiency of agitator.
The utility model provides a kind of adjustable angle joint formula agitator; Be when original stirring cell body parameter of materials changes; Can be through changing the syndeton of CBY blade and shaft, according to the setting angle of design demand adjustment blade, under the prerequisite of guaranteeing agitator power, the requirement of shaft strength and stiffness; Change mixing effect, improve the service efficiency of CBY blade.This stirrer paddle both can have been realized the parameter of materials of the same race interior application of excursion to some extent; Also can be implemented in the exchange between different material in the parameter of materials certain limit; Therefore the adjustable structure of novel setting angle can be applicable to all kinds of dashers; Also can in different industry fields, promote, can practice thrift cost largely, realize good economic benefit and social benefit.
