Abstract
The utility model relates to the improvement of a stirring paddle. The improvement is characterized in that a ceramic impeller is used by the stirring paddle; the outside of a rotating shaft is wrapped by anticorrosive plastic and is wrapped and sheathed by a ceramic tube then; a ceramic nut is used for fastening the impeller. Thus, parts of the stirring paddle contacting media all use anticorrosive, heat insulating and wearable ceramic, and the whole service life of the stirring paddle in anticorrosive and high wearing media is extended.
Description
Utility model is about to the improvement of chemical industry with stirring arm, especially corrodes and the high improvement that wears away medium with stirring arm.
The stirring arm that chemical industry is generally used is made up of rotating shaft and the impeller that is fixed on rotating shaft one end, can be used for Korrosionsmedium for making stirring arm, needs carry out preservative treatment to stirring arm.The preservative treatment of stirring arm has the high molecule plastic of employing impeller usually, and stainless steel is adopted in rotating shaft, Hastelloy, or outside metal rotating shaft, coat plastics, enamel or the like.This still can meet the demands for general Korrosionsmedium, but for severe corrosive and the height abrasion medium that contains particle potassium sulfate for example, the suspended substance of chloride ion-containing, sulfate ion, and in the higher temperature environment, use, plastic impeller, the rotating shaft of outsourcing corrosion resistant plastics are easy to abrasion of particles in the being corroded property medium, and plastic impeller can not be used for the stirring of higher temperature; Cover enamel outward, though wearability increases, but still undesirable, and the manufacturing of enamel coating has relatively high expectations, if the bad pin hole that occurs of enamel coating, then Korrosionsmedium is easy to infiltrate, and very fast corrosion makes aperture enlarge, and same service life is not long.Stainless steel, Hastelloy one are that price is higher, and two corrosion resistants, wearability are good not enough, and still fall short of service life, and therefore still having is worth improved place.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of cheap, corrosion-resistant, wearability and heat resistance all good, the stirring arm of long service life.
The utility model purpose realizes, the main improvement is that the stirring arm impeller adopts ceramic making, behind the metal rotating shaft outsourcing sleeving plastic sleeve pipe, jacket earthenware again, the fastening impeller end of rotating shaft adopts the ceramic nut sealing, partly all adopts corrosion resistant, heatproof and all good ceramic material of wearability thereby stirring arm is contacted with medium, makes stirring arm not only have good corrosion resistance, and have good wear resistance and temperature tolerance, be particularly useful for using in corrosion and the high abrasion medium.Specifically, the utility model stirring arm, comprise metal rotating shaft and the impeller that is fixed in the rotating shaft, it is characterized in that said metal rotating shaft is surrounded by plastic layer outward, plastic layer is with earthenware outward, said impeller is ceramic impeller, and the impeller axis hole has the radial location keyway, and the fastening impeller of rotating shaft has not been held the ceramic nut end socket.
The sleeving plastic layer that the said rotating shaft of utility model is outer can adopt plastic bushing, also can adopt plastic coating, and plastics can be various corrosion resistant plastics, as polyethylene, polypropylene, polyvinylidene fluoride, chlorinated polyether, tetrafluoroethene etc., does not have and places restrictions on especially.The length of the visual rotating shaft of outer jacket earthenware, porcelain bushing can single integral body, also can be made up of more piece, is to improve porcelain bushing internode sealing, avoid Korrosionsmedium to infiltrate the inner plastic sheath of corrosion, ceramic tube coupling end face can be processed into hermetically-sealed constructions such as sealing of band folding or the sealing of tenon mouth.Be the be connected fastness of raising ceramic nut end socket, and improve ceramic nut end socket yield rate that can be arranged with the metal connecting piece that is connected with rotating shaft in the ceramic nut end socket, wherein a kind of preferred metal connector is a metal nuts with metal rotating shaft.Said impeller radial location axis hole keyway, a kind of is the arc keyway preferably, can overcome pottery stress in sintering procedure and concentrate the cracking that causes, and improves the impeller yield rate.
Below in conjunction with a non-limiting embodiment, further specify utility model.
Fig. 1 is a utility model stirring arm basic structure schematic diagram.
Fig. 2 is ceramic impeller keyway structural representation.
Embodiment: referring to accompanying drawing, stirring arm is made up of metal rotating shaft 1 and lower end high alumina ceramic impeller 6.Metal rotating shaft is sheathed with polytetrafluoroethylplastic plastic cover 2 outward, and plastic sheath is sheathed with earthenware 4 outward, and ceramic tube coupling end face has folding sealing 3.Pottery impeller blade angle is 15-45 °, and aperture axis is to being processed with arc keyway 11.It is slightly thin that metal rotating shaft is installed the impeller place, forms a step, and sealing gasket 5 is arranged between step and impeller, and sealing 10 is arranged between ceramic coat and impeller.Axle head has the nut 7 of fastening impeller, and end does not have ceramic nut to piece together cap 9, is provided with metal attaching nut 8 in the pottery assembly cap and is connected with an axle spiral.
Some unsubstantialities of utility model are changed the still true novel protected scope of using, and adopt plastic coating outward as rotating shaft, and plastic layer adopts other corrosion resistant plastics; The overcoat earthenware adopts single; Be the plane butt joint between the more piece earthenware, interplanar is lined with seal washer such as viton gasket, or the tenon sealing; Pottery is pieced together other connectors that are connected with rotating shaft of employing or the like in the cap.
Utility model is because stirring arm especially corrodes with medium and high abrasion medium contacts partly---and impeller, rotating shaft and fastening impeller nut appearance all adopt ceramic material or compound, not only corrosion resistant, heat resistance are good, the mechanical strength height, and solved wear-resisting this technical barrier in corrosive medium, prolonged the whole service life of stirring arm in corrosion and high abrasion medium greatly.Especially the double layer anticorrosive of metal rotating shaft has more improved service life of rotating shaft.Arc keyway in the pottery impeller axis hole, the radial location of impeller and rotating shaft of having determined that not only is situated between preferably, and also not easy to crack in manufacturing process, the yield rate height.The existing anticorrosion stirring arm of utility model has prolonged service life greatly, has reduced maintenance, is particularly useful for using in corrosion and the high abrasion medium.
