Abstract
The invention relates to a dynamic mixer, comprising a housing (10) and an inner body (11) which can be rotated about a common axis in relation to each other and which form a mixing chamber (12); a back shut-off element (20) which delimits the mixing chamber (12) and which has inlet openings (21) for guiding in the components to be mixed, a front outlet (24) for delivering the mixture and a drive element (17) which is located on the rotatable part of the mixer. The inner body (11) is connected to the shut-off element (20) and forms the stator of the mixer, while the housing (10) is provided with the drive (17) and forms the rotor of the mixer.
Claims31
A dynamic mixer comprising a housing and an inner body, which can be rotated relative to one another about a common axis and, at least in part, form a mixing chamber,
- a termination element, which bounds the mixing chamber and has inlet openings for feeding the components which are to be mixed,
- at least one outlet for discharging the mixture, and
- a drive region which is provided on the rotatable part of the mixer,
- the inner body and the termination element forming the stator of the mixer, and the housing forming the rotor of the mixer.
A dynamic mixer for mixing a plurality of components to form a dental compound mixture comprising:
- an inner body
- a housing surrounding the inner body with formation of a mixing chamber,
- inlet openings to the mixing chamber for accommodating supply of components to be mixed,
- at least one outlet for discharging a mixture formed in the mixing chamber, and
- drive structure provided on the housing for accommodating driving of the housing with respect to the inner body to carry out mixing operations in the mixing chamber.
A method of making a dental compound mixture by mixing a plurality of components to form the dental compound mixture using a dynamic mixer which has an inner body, a housing surrounding the inner body to form a mixing chamber together with the inner body, inlet openings to the mixing chamber for supplying respective components, and at least one mixing chamber outlet opening for discharging a dental compound mixture from the mixing chamber, said method comprising:
- supplying components under pressure through the inlet openings to the mixing chamber, and
- mixing the components in the mixing chamber by rotatably driving the housing around the inner body while maintaining the inner body in a relatively fixed position.
A kit including:
- at least one cartridge containing respective viscous components for forming a dental compound, and
- a dynamic mixer for mixing the components from the at least one cartridge, said dynamic mixer comprising:
- an inner body
- a housing surrounding the inner body with formation of a mixing chamber,
- inlet openings to the mixing chamber for accommodating supply of components to be mixed,
- at least one outlet for discharging a mixture formed in the mixing chamber, and
- drive structure provided on the housing for accommodating driving of the housing with respect to the inner body to carry our mixing operations in the mixing chamber.
A cartridge adapted to supply at least one component to a dynamic mixer for mixing a plurality of components to form a dental compound mixture, said dynamic mixer comprising:
- an inner body
- a housing surrounding the inner body with formation of a mixing chamber,
- inlet openings to the mixing chamber for accommodating supply of components to be mixed, at least one outlet for discharging a mixture formed in the mixing chamber, and
- drive structure provided on the housing for accommodating driving of the housing with respect to the inner body to carry our mixing operations in the mixing chamber,
- wherein said cartridge is adapted to interface with at least one of said inlet openings during mixing operations.
