Description
Technical field
The utility model relates to a kind of agitator.
Background technology
The material of existing agitator is various, and glassed agitator is arranged, and is cheap and easy to get, but anti-collide with, beat with impact resistance poor; Metal agitator anti-falls that to bump performance good, but corrosion resistance is poor; The enamel agitator though anticorrosion ability is remarkable, has also been inherited the shortcoming of glassed agitator, anti-collides with, beats with impact resistance poor, and service life is shorter; And metal outsourcing anticorrosive coat agitator, Corrosion Protection and anti-falling are bumped function admirable, but in a single day crackle or breakage appear in anticorrosive coat; Promptly lose decay resistance, cause agitator in corrosive medium, to damage rapidly, can't continue to use; And basically all can't keep in repair, only can change new stirrer.Therefore, need a kind of existing outstanding Corrosion Protection that a kind of agitator than the long life is arranged again.
In addition; Prior art is mainly carried out around structure the improvement of agitator; Make every effort to simple in structure, applied widely, mixing effect is good, also not find the anti-of agitator self collided with, beats with impact resistance and improve the service life that research improves agitator.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of cost relatively low and have the excellent anti corrosive nature and anti-collide with, beat with impact resistance good, the agitator that service life is long.
The utility model provides a kind of agitator, and this agitator comprises shaft and blade, and blade is arranged on an end of shaft, it is characterized in that, said shaft and blade comprise base material separately and be coated on the polytetrafluoroethylene (PTFE) clad on the base material outer surface.
The agitator that the utility model provides is owing to the outer surface at blade and shaft has the polytetrafluoroethylene (PTFE) clad separately; Therefore can when guaranteeing enamel and glassed agitator each item excellent properties, improve advantages such as whole thermal shock resistance and the anti-performance of colliding with, the life cycle that has prolonged agitator greatly.
Compared with prior art, the beneficial effect that agitator had of the utility model is:
1, decay resistance is strong, and is applied widely, can be used to be lower than deep-etching occasions such as 200 ℃ of any strong acid, highly basic; But secure replacement chemical industry, oil, the original enamel of medicine and other fields and glassed agitator, and prolong its service life greatly.
2, good thermal shock resistance and the anti-performance of colliding with.
3, good smooth surface performance effectively reduces material and adheres to.
Description of drawings
Accompanying drawing is the further understanding that is used to provide the utility model, and constitutes the part of specification, is used to explain the utility model with the following specific embodiment, but does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation that the outer surface of a kind of embodiment of providing of the utility model has the agitator of polytetrafluoroethylene (PTFE) clad;
Fig. 2 is the structural representation that the outer surface of the another kind of embodiment that provides of the utility model has the agitator of polytetrafluoroethylene (PTFE) clad;
The cross-sectional view of the shaft of agitator shown in Figure 3.
The specific embodiment
Further specify below in conjunction with the agitator of accompanying drawing the utility model.
Like Fig. 1, Fig. 2 and shown in Figure 3; The agitator that the utility model provides; Comprise shaft 2 and blade 1, blade 1 is arranged on an end of shaft 2, and said shaft 2 comprises base material 22 separately and is coated on the polytetrafluoroethylene (PTFE) clad 21 on base material 22 outer surfaces with blade 1.
According to the utility model, as long as the outer surface of said shaft 2 and blade 1 has the purpose that polytetrafluoroethylene (PTFE) clad 21 can be realized the utility model separately, but under the preferable case, the thickness of said polytetrafluoroethylene (PTFE) clad 21 is 0.6-3.5mm.In above-mentioned scope; Can guarantee that agitator has sufficient corrosion resistance on the one hand; Resist and collide with, beat and impact resistance; Suitable on the other hand thickness can reduce crackle or the damaged generation that the polytetrafluoroethylene (PTFE) clad causes owing to the difference of the coefficient of expansion in the environment that colds and heat succeed each other, can guarantee that also cost is relatively low.
The thickness of the polytetrafluoroethylene (PTFE) clad 21 of the polytetrafluoroethylene (PTFE) clad 21 of the outer surface of said blade 1 and the outer surface of said shaft 2 can be the same or different; Under the preferable case, the thickness of the polytetrafluoroethylene (PTFE) clad 21 of the outer surface of said blade 1 can be 1.0-3.5mm.The thickness of the polytetrafluoroethylene (PTFE) clad 21 of the outer surface of said shaft 2 can be 0.6-3mm.
What form said polytetrafluoroethylene (PTFE) clad 21 can be existing various forms of polytetrafluoroethylene (PTFE), and preferably polytetrafluoroethylene proportion is greater than 2.1g/cm
3, wherein the number-average molecular weight of polytetrafluoroethylene (PTFE) is not less than 6,000,000, and vitrification point is not less than 327 ± 5 ℃.
Said shaft 2 can can be that truncated cone-shaped, the other end are columniform shape for an end also for cylindrical for example for well known to a person skilled in the art different shape.
An above-mentioned end is that truncated cone-shaped, the other end are that the shaft of columniform shape can improve speed of agitator under identical stirring power.Therefore preferred said shaft 2 end that is provided with paddle 1 is a truncated cone-shaped, and the other end is cylindrical.The size of shaft can be confirmed according to concrete applied field is incompatible, be specially conventionally known to one of skill in the art.
