Description
Technical field
The utility model relates to field of chemical equipment, is specifically related to a kind of wide ribbon sawtooth agitator.
Background technology
Agitator makes liquid, gas medium forced convection mixed uniformly device.Agitator mainly comprises following several types: 1, propeller mixer, and be made up of 2 ~ 3 pusher propeller leaves, working speed is higher, and the peripheral speed of blade outer rim is generally 5 ~ 15m/s.Propeller mixer mainly causes axial liquid stream, produces larger internal circulating load, be applicable to stir low-viscosity (mobile) liquid, emulsion and solia particle content lower than 10% suspension.2, turbine agitator, formed by installing 2 ~ 4 straight or bending blades on centrifugal disc.The ratio of the external diameter of blade, width and height, be generally 20:5:4, peripheral speed is generally 3 ~ 8m/s.Turbine causes the Radial Flow of height turbulence when rotated, is applicable to dispersion and the liquid liquid phase reaction course of gas and immiscible liquid.3, dasher, has flat paddle and oblique paddle two kinds.Flat-blade paddle agitator is made up of the straight blade of two panels.Diameter of propeller blade is 4 ~ 10 with the ratio of height, and peripheral speed is 1.5 ~ 3m/s, and the radial flow of liquid speed produced is less.Two leaves of inclined paddle type agitator are turned back 45 ° or 60 ° on the contrary, thus produce axial liquid stream.Dasher structure is simple, is usually used in the mixing of low-viscosity (mobile) liquid and the dissolving of solia particle and suspension.4, anchor agitator, blade outer rim shape and tank diameter inwall want consistent, only have very small―gap suture therebetween, can remove the viscous reaction product be attached on cell wall or the solids being piled up in bottom land, keep good heat-transfer effect.5, helix(ribbon type) agitator, is specifically designed to and stirs high viscosity liquid and pseudoplastic fluid, usually operate under laminar condition.
Utility model content
Technical problem to be solved in the utility model is: provide the wide ribbon sawtooth agitator that a kind of applicability is wide, stirring efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wide ribbon sawtooth agitator, comprise: shaft and stirring ribbon, the external diameter of described stirring ribbon is equal with pitch, described stirring ribbon along shaft axis direction from the top down spiral surrounding around shaft, described stirring ribbon welds mutually with shaft, and the cylindrical of described stirring ribbon is provided with sawtooth.
Preferably, in above-mentioned wide ribbon sawtooth agitator, the setting triangular in shape of described sawtooth.
Preferably, in above-mentioned wide ribbon sawtooth agitator, the radial dimension of described stirring ribbon is all equal from top to bottom.
Preferably, in above-mentioned wide ribbon sawtooth agitator, described stirring ribbon is solid sheet.
Preferably, in above-mentioned wide ribbon sawtooth agitator, be seamless welding between described stirring ribbon and shaft.
Preferably, in above-mentioned wide ribbon sawtooth agitator, described stirring ribbon is two ribbons.
Preferably, in above-mentioned wide ribbon sawtooth agitator, described stirring ribbon is made up of stainless steel material.
The utility model beneficial effect is: the utility model, by arranging sawtooth at the cylindrical stirring ribbon, has decomposition to material during stirring and breaks up effect; Stirring ribbon width by increasing, adopting seamless welding between stirring ribbon and shaft, thus increase lifting rate, axial convection effects is stronger.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of wide ribbon sawtooth agitator in the utility model;
Fig. 2 is the structural representation of ribbon in the utility model;
Fig. 3 is the partial enlarged drawing along the place of A shown in Fig. 2.
In Fig. 1 to Fig. 3: 1, shaft, 2, stir ribbon, 3, cylindrical, 4, sawtooth.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.The example of these preferred embodiments illustrates in the accompanying drawings.Shown in accompanying drawing and the embodiment of the present utility model described with reference to the accompanying drawings be only exemplary, and the utility model is not limited to these embodiments.
At this, also it should be noted that, in order to avoid the utility model fuzzy because of unnecessary details, illustrate only in the accompanying drawings with according to the closely-related structure of scheme of the present utility model and/or treatment step, and eliminate other details little with the utility model relation.
Refer to Fig. 1, a kind of wide ribbon sawtooth agitator, comprise: shaft 1 and stirring ribbon 2, the external diameter of described stirring ribbon 2 is equal with pitch, spiral surrounding is around shaft 1 from the top down along the axis direction of shaft 1 for described stirring ribbon 2, and described stirring ribbon 2 is solid sheet, is seamless welding between described stirring ribbon 2 and shaft 1, thus increasing lifting rate, axial convection effects is stronger.Refer to Fig. 2 and Fig. 3, the cylindrical 3 of described stirring ribbon 2 is provided with sawtooth 4, and in the present embodiment, described zigzag fashion is preferably triangle.The setting of sawtooth 4 can be carried out decomposition to material and break up, and the radial dimension of described stirring ribbon 2 is all equal from top to bottom.In the present embodiment, described stirring ribbon 2 is preferably two ribbon, thus accelerates mixing velocity, improves mixing efficiency.Described stirring ribbon 2 is made up of stainless steel material, thus has the effect of wear resistant corrosion resistant, adds the service life of stirring ribbon, reduces cost.During installation, the top of shaft 1 is connected with drive unit (not shown), and drive unit drives shaft to rotate.
In the utility model, the operation principle of wide ribbon sawtooth agitator is: by running up of shaft 1, material is made to smash decomposition fast under the effect of stirring the outer crenature of ribbon, material after decomposition is along ribbon blade axial flow, produce strong convection vortex, storeroom produces strong shear degradation and convection current, reaches rapid decomposition, mixed uniformly effect.
In sum, the wide ribbon sawtooth agitator applicability in the utility model is comparatively wide, and by modular design, manufactures more for convenience, by arranging sawtooth 4 at the cylindrical 3 stirring ribbon 2, having decomposition break up effect during stirring to material; Stirring ribbon width by increasing, adopting seamless welding between stirring ribbon and shaft, thus increase lifting rate, axial convection effects is stronger.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
