Abstract
The utility model discloses a helical ribbon type blade. The helical ribbon type blade comprises a stirring shaft, a helical ribbon having a certain screw pitch and prepared from helical steel belts, and a supporting rod for connecting the helical ribbon with the stirring shaft; the helical ribbon type blade is characterized in that the helical ribbon comprises an outer helical ribbon and an inner helical ribbon, wherein the radial distance from the outer helical ribbon to the axis of the stirring shaft is larger than that from the inner helical ribbon to the axis of the stirring shaft; the outer helical ribbon and the inner helical ribbon are opposite in spiral direction. During a stirring process, a material passing through the inner helical ribbon and the material passing through the outer helical ribbon are opposite in direction of motion, so that the stirring effect can be well improved.
Description
Technical field
The utility model relates to a kind of blade that stirs use, particularly a kind of helical-ribbon type blade.
Background technology
Helix(ribbon type) agitator is a kind of widely used agitator, is generally used for the mixing of medium-high viscosity fluid foods and group's powder.When stirring, the mobile of material is by ribbon rotary action, ribbon material is around done upwards and circumferential movement, and the middle material of kettle moves downward, thereby forms upper and lower, inside and outside circulating, and reaches the objects such as even mixing and heat transfer.For single helical-ribbon type blade, when the single helical-ribbon type blade of material process, material can only move along a direction, be upwards spiral or spiral downwards, because the unicity of motion can not stir material fully, and change the direction of motion of material along blade by the direction of rotation that changes stirring motor, increase cost, and while changing the direction of rotation of stirring motor, motor has individual stopped process, stirring efficiency is reduced; In addition, because the pitch of helical-ribbon type blade is larger, make troubles to processing.
Utility model content
The technical problems to be solved in the utility model is the present situation for prior art, and the helical-ribbon type that a kind of mixing effect is good, stirring efficiency is high blade is provided.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of helical-ribbon type blade, comprise shaft, there is the ribbon that the spirality steel band of a constant pitch makes and the support bar that connects this ribbon and this shaft, it is characterized in that: described ribbon comprises outer ribbon and interior ribbon, described outer ribbon to the radial distance of the axis of described shaft is greater than the radial distance of described interior ribbon to the axis of described shaft, and the hand of spiral of described outer ribbon and described interior ribbon is contrary.
As improvement, the pitch of described outer ribbon and described interior ribbon not etc., is not selected preferably, and in the pitch ratio of described outer ribbon, the pitch of ribbon is large.
Improve, half section of described outer ribbon is dextrorotation again, and the described interior ribbon pitch corresponding with the outer ribbon of this dextrorotation is little and be left-handed; Another half section of described outer ribbon is left-handed, and the corresponding described interior ribbon pitch of the outer ribbon left-handed with this is little and be dextrorotation.On same ribbon, change the hand of spiral, on the one hand, be conducive to material and move back and forth along shaft, improve stirring extent; The axial force balance that on the other hand, can also make shaft be subject to.
Improve, described helical-ribbon type blade also comprises the axle sleeve that connects described support bar and described shaft again, and this axle sleeve adopts shroud ring to be connected with this shaft, is convenient to the dismounting of ribbon.
Compared with prior art, owing to the utility model has the advantage of: interior ribbon and outer ribbon that the hand of spiral is contrary are set on same shaft, make shaft in rotary course, through the material of interior ribbon and the material movement opposite direction of the outer ribbon of process, there are two reciprocal motions in material on same shaft simultaneously like this, is conducive to improve mixing effect, and in this process, do not need the direction of rotation of stirring motor to change, improved stirring efficiency yet.
Brief description of the drawings
Fig. 1 is the structural representation of helical-ribbon type blade in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the helical-ribbon type blade in this enforcement, comprises shaft 1, has the ribbon that the spirality steel band of a constant pitch makes and connect this ribbon and the support bar 5 of this shaft 1.
Wherein, ribbon comprises outer ribbon 2 and interior ribbon 3, outer ribbon 2 to the radial distance of the axis of shaft 1 is greater than the radial distance of interior ribbon 3 to the axis of shaft 1, the hand of spiral of outer ribbon 2 and interior ribbon 3 is contrary, and in the pitch ratio of outer ribbon 2, the pitch of ribbon 3 is large, simultaneously, half section of outer ribbon 2 is dextrorotation, the interior ribbon 3 corresponding with the outer ribbon 2 of this dextrorotation is left-handed, and another half section of outer ribbon 2 is left-handed, and corresponding interior ribbon 3 pitch of the outer ribbon 2 left-handed with this are dextrorotation.Interior ribbon 3 and outer ribbon 2 that the hand of spiral is contrary are set on same shaft 1, on the one hand, make shaft 1 in rotary course, through the material of interior ribbon 3 and the material movement opposite direction of the outer ribbon 2 of process, there are two reciprocal motions in material on same shaft 1 simultaneously like this, be conducive to improve mixing effect, and in this process, do not need the direction of rotation of stirring motor to change yet, improve stirring efficiency, on the other hand, because the external diameter of interior ribbon 3 is less than the external diameter of outer ribbon 2, pitch less than normal has been brought easy to manufacture.
In addition, helical-ribbon type blade also comprises the axle sleeve 4 that connects described support bar 5 and shaft 1, and this axle sleeve 4 adopts shroud ring to be connected with this shaft 1, is convenient to the dismounting of ribbon.
Claims (5)
1. a helical-ribbon type blade, comprise shaft, there is the ribbon that the spirality steel band of a constant pitch makes and the support bar that connects this ribbon and this shaft, it is characterized in that: described ribbon comprises outer ribbon and interior ribbon, described outer ribbon to the radial distance of the axis of described shaft is greater than the radial distance of described interior ribbon to the axis of described shaft, and the hand of spiral of described outer ribbon and described interior ribbon is contrary.
2. helical-ribbon type blade according to claim 1, is characterized in that: the pitch of described outer ribbon and described interior ribbon is not etc.
3. helical-ribbon type blade according to claim 2, is characterized in that: in the pitch ratio of described outer ribbon, the pitch of ribbon is large.
4. according to the helical-ribbon type blade described in claims 1 to 3 any one, it is characterized in that: half section of described outer ribbon is dextrorotation, and the described interior ribbon corresponding with the outer ribbon of this dextrorotation is left-handed; Another half section of described outer ribbon is left-handed, and the corresponding described interior ribbon of the outer ribbon left-handed with this is dextrorotation.
5. helical-ribbon type blade according to claim 4, is characterized in that: described helical-ribbon type blade also comprises the axle sleeve that connects described support bar and described shaft, and this axle sleeve adopts shroud ring to be connected with this shaft.
