Abstract

The utility model relates to a blender, in particular to a blender for a kettle which comprises a mixer shaft and a blade. A plurality of blades, which are spirally and upwardly arranged along the axial center of the mixer shaft, are provided on the place with a certain distance from the axial center of the mixer shaft, and each blade is fixedly connected with the mixer shaft through a connecting stem. Each blade with upward and spiraling design equips the utility model with excellent stirring effect of a helix agitator. As each blade is connected with the mixer shaft through the connecting stem, thereby, the manufacture process of the utility model is easier than the helix agitator, and manufacturing cost is lower and large paddles-making is easier.

Description

A kind of agitator

Technical field

The utility model relates to a kind of agitator, particularly a kind of agitator that is applied in the still.

Background technology

The present helix(ribbon type) agitator that uses in still is a kind of agitator of type at a slow speed, generally operate in the laminar region, according to its planform, can be in the liquid along helicoid generation axial circulation up or down, oppositely inside and outside ribbon has then been strengthened the circulation of liquid inner peripheral, thereby produce circulation up and down, processes such as the mixing of high viscosity liquid and heat transfer in being adapted to stir effectively non-Newtonianism, plastics and memory fluid especially; But helix(ribbon type) agitator makes relatively that difficulty, welding deformation are big, precision be cannot say for sure card, and along with the increase of diameter, difficulty of processing is also big more.

Summary of the invention

The purpose of this utility model is the deficiency that solves above-mentioned agitator, and provide a kind of easy to process, make the agitator that adult is low, can substitute helix(ribbon type) agitator

The purpose of this utility model is achieved by the following technical solution: a kind of agitator, include shaft and blade, also be provided with a plurality of blades that rise and arrange along shaft axle center spiral from a distance, shaft axle center, each blade is fixedly connected by connecting rod and shaft respectively.

The beneficial effects of the utility model are: each blade is set as the spiral rising arranges, promptly possess helix(ribbon type) agitator good mixing effect, simultaneously since each blade be connected with shaft by connecting rod respectively, so than the easier processing and manufacturing of helical ribbon agitator, low cost of manufacture and than being easier to make large-scale oar.

Description of drawings

Fig. 1 is the utility model example structure schematic diagram

Fig. 2 is the schematic perspective view of the utility model embodiment.

The specific embodiment

Now in conjunction with the accompanying drawings the utility model is further described:

By Fig. 1, as can be known shown in Figure 2, a kind of agitator of the utility model includes shaft 1 and blade 2, also is being provided with a plurality of blades that rise and arrange along shaft 1 axle center 11 spirals from 11 a distance, shaft 1 axle center, each blade is fixedly connected by connecting rod 3 and shaft 1 screw thread respectively.Arrange by each blade being set as the spiral rising, both possessed helix(ribbon type) agitator good mixing effect, simultaneously since each blade be connected with shaft by connecting rod respectively, so than the easier processing and manufacturing of helical ribbon agitator, low cost of manufacture and than being easier to make large-scale oar.And connecting rod 3 and shaft 1 screw thread are fixedly connected and make the blade convenient disassembly, thereby make the agitator installation and maintenance more convenient, and simultaneously, shaft is not yielding yet.But obvious, connecting rod 3 also can be fixed by alternate manners such as welding with shaft 1.Usually, also every connecting rod is set as spiral up-wards inclination shape, thereby makes each blade constitute more complete ribbon form, make the mixing effect of the more approaching general helical ribbon agitator of mixing effect.Certainly, blade is not made spiral up-wards inclination shape, as the inclination of normal angled making, also when within the utility model protection domain.

In illustrated embodiment, described each bar connecting rod (31,32,33,34,35) (31 ', 32 ', 33 ', 34 ', 35 ') is orthogonal with shaft 1, because make vertically, its stationarity can be than making the good of inclination, so make mutual vertical configuration usually.

In the diagram, in same plane, be provided with two connecting rods (21,21 ') and two connecting rods (21,21 ') connect along shaft 1 symmetry, two connecting rods (31 on each plane, 31 ') (32,32 ') (33,33 ') (34,34 ') (35,35 ') blade (21 on, 22,23,24,25) (21 ', 22 ', 23 ', 24 ', 25 ') constitute two ribbons (2,2 ') the spiral rising is arranged, certainly, the connecting rod that also can establish in same plane more than three or three makes the blade on each connecting rod constitute many helical ribbon, perhaps in same plane, only establish a connecting rod and a corresponding blade and constitute single ribbon arrangement, but two ribbon forms that the connecting rod of establishing two usually becomes the installation site of symmetry shape and the blade on it also to become symmetry to constitute, during stirring, the agitator operation can be more steady, and mixing effect also can satisfy the requirement that material stirs in the general still basically.

Described every connecting rod (31,31 ') (32,32 ') (33,33 ') (34,34 ') (35,35 ') be provided with in, outer two leaf blades (21,41) (22,42) (23,43) (24,44) (25,45) (21 ', 41 ') (22 ', 42 ') (23 ', 43 ') (24 ', 44 ') (25 ', 45 '), on each bar connecting rod interior (21,22,23,24,25) (21 ', 22 ', 23 ', 24 ', 25 '), outward (41,42,43,44,45) (41 ', 42 ', 43 ', 44 ', 45 ') blade constitute between respectively corresponding in, external spiral rises and arranges, and in described usually, the blade spiral one-tenth rightabout as shown in the figure that external spiral rises and arranges, thereby two hurricane bands (4 inside and outside making when stirring, 4 ') (2,2 ') one produces the stirring that mixing power makes progress, another produces the downward stirring of spiral power, make the material in the still stir more abundant, mixing effect is better, certainly, also can on every connecting rod, establish the helical stir that leafy blade constitutes multilayer as required.

Among the embodiment as shown in the figure, angle is 90 degree between the connecting rod on the described adjacent plane, according to the size of still, also it angle can be established smallerly, makes the arrangement of blade tightr.
