Description
Tambour de centrifuge. On sait que les centrifu;@es sont Irèfré- quemment employées pour le turbinage de liquides acides ou alcalins. Il est fréquem ment .difficile dans ces cas :d'employer .des matériaux .de construction appropriés, parce que les métaux pratiquement employables, tels que le cuivre, l'aluminium, le nickel etc., ne conviennent. pas encore pour tous les cas, ces métaux, bien que résistant aux influences cliimi.ques, produisant souvent .des effets in désirables sur la matière à. turbiner comme c'est par exemple le cas dans les teinture ries.
On a cherché à y remédier en revêtant les tambours métalliques de substances non métalliques appropriées. comme par exem ple le caoutelioua durci. Toutefois, ces revête ments ne sont pas très durables, parce qu'ils (el.atent facilement: par suite de la. dilatation inégale de la matière dont est construit le tambour, ainsi que de la matière constitutive (lu revêtement et qu'ils sont alors hors d'état de servir.
Or on a reconnu que les résines artificielles, par exemple celles obtenues comme produits de condensation de formal- dehyde et phénol, sont des corps très résis- tants aux bains alcalcins et acides, et qu'une matière formée de résine artificielle et de matière fibreuse possédait aussi nue. résis tance suffisante.
L'objet de la présente invention est un tambour de centrifuge .dont le manteau est en matière formée de résine artificielle et (le matière fibreuse.
Le dessin annexé représente une forme d'exécution, donnée à, titre d'exemple, d'un tambour de centrifuge suivant l'invention.. L'arbre N porte le fond de tambour P fabri qué en métal ou en toute autre matière ap propriée, auquel est fixé par des vis S le manteau T. Ce manteau est en matière for mée de résine artificielle et de matière fi breuse et, .dans la forme d'exécutiolz repré sentée, il est pourvu, intérieurement et exté rieurement d'un revêtement U. par exemple en cellon, celluloïd etc.
D est le couvercle chi tambour, qui, -dans la forme d'exécution re présentée, est assujetti à force au man teau T.
Centrifuge drum. It is known that centrifuges are frequently employed for the turbining of acidic or alkaline liquids. In these cases it is often difficult to use. Suitable construction materials, because practically employable metals, such as copper, aluminum, nickel etc., are not suitable. not yet in all cases, these metals, although resistant to cliimi.ques influences, often producing undesirable effects on the material. turbinate as is the case, for example, in dyes.
An attempt has been made to remedy this by coating the metal drums with suitable non-metallic substances. such as, for example, the hardened caoutelioua. However, these coatings are not very durable, because they (el.atent easily: owing to the unequal expansion of the material of which the drum is made, as well as of the constituent material (read coating and that they. are then unable to serve.
Now it has been recognized that artificial resins, for example those obtained as condensation products of formaldehyde and phenol, are substances very resistant to alkaline and acid baths, and that a material formed of artificial resin and fibrous material also possessed nude. sufficient resistance.
The object of the present invention is a centrifuge drum, the mantle of which is made of material formed of artificial resin and (the fibrous material.
The appended drawing shows an embodiment, given by way of example, of a centrifuge drum according to the invention. The shaft N carries the bottom of the drum P made of metal or any other suitable material. property, to which the mantle T. is fixed by screws S. This mantle is made of a material formed of artificial resin and a fibrous material and, in the execution form shown, it is provided, internally and externally with a U coating, for example of cellon, celluloid etc.
D is the drum cover, which, in the embodiment shown, is forcibly attached to the sleeve T.
