Abstract
A kind of acid-proof wear-proof high temperature resistant agitating paddle, one or more stirrer paddle is provided with the lower end of cylinder agitating shaft；In the outside of agitating shaft and stirrer paddle, one layer of enamel is first warded off；Again in the acid proof coating such as the outside of enamel layer, one strata tetrafluoroethene of parcel；In the outside of acid proof coating, then wrap up the fibrous protective layers such as one layer of Carbon fibe；In the outside of the fibrous protective layer of agitating shaft, then apply the wear-resistant daubs such as one layer of carborundum；In the outside of the fibrous protective layer of blade, then cover the nonmetallic wear-resistant protection set such as one layer of carborundum.The beneficial effects of the utility model are：Provide a kind of can wear the agitating paddle that is used for a long time in slurry by force in high temperature and pressure strong acid.
Description
Technical field
The utility model belongs to the industry agitating paddle manufacturing technology field such as metallurgy, chemical industry.
Technical background
Stirring is to accelerate chemical reaction to complete, so as to be to speed up the important means of speed of production；Agitating paddle is metallurgical, chemical industry
The tool of production important etc. industry.Existing various variously-shaped, material agitating paddles, but it is all common scarce there are one
Fall into --- it cannot be used in high temperature and pressure strong acid wears by force slurry.By taking hydrochloric acid flyash slurry as an example, in 140 DEG C of temperature,
Under the operating mode of 0.6MPa pressure, no existing agitating paddle of any type can use for a long time in this slurry：Enamel stirs
Paddle service life 3-5 days, is no longer than 10 days；Enamel wraps up agitating paddle service life 5-8 days of tetrafluoro again, is no longer than
It 15 days, can not meet demand of industrial production at all, finally can only will be changed to vertical nothing with horizontal single reaction kettle dissolving-out process is stirred
Multi-reaction kettle series connection dissolving-out process is stirred, not only equipment is complicated by the latter, takes up a large area, it is most important that reaction speed is slow, molten
It is the former more than twice to go out the time.
The purpose of this utility model, which seeks to offer one kind, to be made for a long time in high temperature and pressure strong acid wears by force slurry
Agitating paddle.Maximum operation (service) temperature in strong acid wears by force slurry up to more than 200 DEG C, service life up to 300 days with
On.
The content of the invention
A kind of acid-proof wear-proof high temperature resistant agitating paddle, one or more agitating paddle is provided with the lower end of cylinder agitating shaft
Leaf, in the outside of agitating shaft and stirrer paddle, first wards off one layer of enamel protective layer；A strata is wrapped up again in the outside of enamel protective layer
Tetrafluoroethene (including its modified material) protective layer；Wrap up one layer of oxytalan protection again in the outside of polytetrafluoroethylene (PTFE) protective layer
Layer；One layer of wear-resistant protection clay is applied again in the outside of the oxytalan protective layer of agitating shaft；Protected in the oxytalan of stirrer paddle
The outside of sheath covers one layer of nonmetallic wear-resistant protection set again.Enamel layer acid-resistant and anti-high-temperature, there is very long service life at spindle nose,
And enamel spindle nose can realize the sealing under high temperature and pressure strong acid operating mode.But enamel layer is crisp, whipping process axis and stirrer paddle
In, deform after the stress of lower part, damaged to making its surface enamel layer cracked；Thus, wrap one layer again outside enamel layer
Polytetrafluoroethylene (PTFE) protective layer；Polytetrafluoroethylene (PTFE) will not cracking, but high temperature is not wear-resisting, and have the phenomenon of transmuting, and service life is not yet
It is long；Wrap up one layer of Carbon fibe or other oxytalan materials again in the outside of polytetrafluoroethylene (PTFE) protective layer, on the one hand, polytetrafluoroethyl-ne
Alkene thermal coefficient of expansion is big, and the Carbon fibe coefficient of expansion is small, the carbon fibre material wrapped up up under room temperature or low-temperature condition, in temperature liter
Gao Houhui tightly fastens polytetrafluoroethylene (PTFE), prevents its high temperature from gliding；On the other hand, ptfe surface is too sliding, wear-resisting painting
Layer can not be smeared, and one layer of carborundum wear-resistant daub can easily be applied in the outside of Carbon fibe material, so as to make polytetrafluoroethylene (PTFE)
Protective layer substantially prolongs the service life of polytetrafluoroethylene (PTFE) protective layer from abrasion！As long as polytetrafluoroethylene (PTFE) protective layer does not damage
Bad, agitating paddle can just work normally, and service life also just substantially prolongs.Because stirrer paddle front end linear velocity is big, abrasion is special
Seriously, can not only be met the requirements by wear-resistant daub.We are served as a contrast in blade with sets such as the high-strength thin carborundum sets of special designing
On, it can be ensured that blade has sufficiently long service life.
The beneficial effects of the utility model are：Providing one kind can be in high temperature and pressure strong acid wears by force slurry for a long time
The agitating paddle used.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
