B. 0,75 Anteilen Kohlenstoff, 4,3 Anteilen Silizium, 15 Anteilen Crom, 3,5 Anteilen Eisen, 3,1 Anteilen Bor und restlichen Anteilen Nickel, mit Hilfe unterschiedlicher Auftragsverfahren mit einer Schichtdicke bis zu 1 mm auf Außenkanten (4) und Flanken (5) zum Zwecke der Erhöhung der Standzeiten aufgetragen wird.
摘要:
A self-cleaning mixer (10) includes a cylindrical housing (21) and a feedscrew (51) extending longitudinally through the housing for mixing water and cement and coveying the slurry through the housing. A chute (23) at the infeed end of the housing receives a batch of material and directs the material into the housing. The feedscrew turns on a hollow shaft (25) including a plurality of outwardly directed nozzles (46, 47, 71-76) along a portion of the length of the shaft. The housing includes a plurality of inwardly directed nozzles (41, 42, 61, 63) fed from a pair of manifolds (44, 62). During a cleaning cycle, one of the manifolds is shut off, thereby increasing the water pressure in the other manifold and increasing the force of the spray to enhance cleaning. The housing is slightly inclined to provide gravity feed of slurry in addition to the feedscrew.

The invention relates to a facility suitable for coating the inside of a pipe element with a mortar. It includes a feeding device (32) suitable for feeding the dry matter of the mortar, the feeding device including a feeding chamber (48) and a member (54) for transporting the dry matter, arranged in the feeding chamber, the feeding chamber being provided with a dry matter inlet (50) and a dry matter outlet (52). The facility also includes a mixing device (34) suitable for mixing the dry matter with liquid matter in order to obtain the mortar, said mixing device having a mixing member (82) and a chamber (74) for mixing the dry matter with the liquid matter. The mixing chamber has a dry matter inlet (76), a liquid matter inlet (78) and a mortar outlet (80). The dry matter outlet (52) of the transport device leads into the dry matter inlet (76) of the mixing chamber, and the feeding member (54) and the mixing member (82) are separate members. The invention can be used for the production of wastewater pipes.

The invention relates to a concrete pump with two possible embodiments of the mixing chamber. Said mixing chamber can be produced with a domed end-cap, welded directly to the chamber or a flat end-cap fitted directly to the chamber by means of bolts. The latter embodiment of the end-cap permits an easier access to the chamber and thus facilitates handling or replacement operations for the blades of the mixer or the axle thereof. Said chamber is provided with an interchangeable curved wear lining. Said lining in protective metal sheet, protects the interior of the mixing chamber against the scraping of the materials.

Le godet malaxeur comporte, située dans l'auge, une vis (9) du type à deux hélices : une hélice interne (19) et une hélice externe constituée de pales (20). Les pales (20) sont structurées et fixées sur l'hélice interne (19) d'une manière qui permet de réaliser un certain équilibrage des efforts et en particulier de leur déformation sous charge. L'hélice interne (19) est constituée de secteurs plans assemblés entre eux au niveau de leur extrémité au moyen d'une portion radiale (61). Cette vis de mélange est couverte par une grille (25) constituée de deux volets (26) et (27) qui se replient l'un sur l'autre pour dégager l'ouverture du godet. Ce godet malaxeur convient pour la préparation de béton ou autre.
