Definitions
- Vibromixer for mixing liquids, liquids with gases or solids in flexible disposable containers
- the invention relates to a Vibromischer for mixing liquids, liquids with gases or solids, consisting of a container made of flexible plastic and a drive shaft with a arranged at its lower end mixer plate, wherein the container is mounted in a support container.
- Such a vibratory mixer is described in CH 289065 for mixing liquids.
- the drive is usually pneumatic or electromagnetic, with a vertical vibration of 50 to 60 Hz is transmitted to a stirrer.
- the electromagnet is operated with mains current, which generates an alternating field in the vertical direction and thus attracts a magnetizable steel plate vertically.
- the springs mounted on the steel plate are compressed.
- the energy stored in the spring pushes the steel plate back to its original position.
- the vibration vedoppelt against that of the alternating current that is, an alternating current of 50 Hz generated on the electromagnet, a vibration of the mixing element of 100 Hz.
- EP 0653960 proposes the production of the mixture by means of a magnetic stirrer near the bottom within the disposable container before. Again, only a locally sufficient mixing quality can be achieved and is therefore not applicable for larger container volume. Another disadvantage of magnetic stirrers is the life of the bearings. In addition, non-plastic materials are in the disposable system, which must be laboriously removed before disposal or recycling.
- the utility model DE 202008016498U describes a container with a flexible container wall and a hollow mixing shaft in the container interior, which is guided through the container wall and communicatingly connected to the mixer.
- the hollow mixing shaft is designed to be stabilizable with the supply of a flowable medium from the outside. This allows the improvement of known containers in the sense that the part of the mixer shaft projecting into the container interior is foldable and the container can be folded into a small package size.
- the efficiency of the transfer of the mixing energy from the mixer to the mixer plate and finally into the medium to be mixed is highly dependent on the stability of the mixer shaft.
- To stabilize the mixer shaft is the addition of a flowable medium needed.
- DE 202007005400U U1 describes a container with flexible container wall, which is used in a support container for mixing a liquid medium, wherein the lateral support surface has at least one side wall of the container forming, the mixing process assisting baffle.
- a mixing shaft made of solid plastic is connected to a mixing drive outside the container.
- a mixing element made of plastic is arranged, which may also be a vibrating mixer element.
- type of mixing shaft is connected to the mixing element and whether this compound is permanently or from outside the container locked and / or detachable.
- US 8342737 B2 describes a flexible disposable container in which a hollow, stable drive shaft is guided by the upper container wall and is tightly connected to the flexible container wall.
- the drive shaft is connected outside the container with a vibration drive and within the container to at least one mixer plate with conical bores.
- the mixer shaft is not detachably connected to the flexible container and can thus be made operational again after use only with great effort and reused.
- the object of the invention is to provide a device which overcomes the disadvantages described and provides a simplified Vibromischer with a way use of the mixing or mixing container with high mixing efficiency and mixing quality.
- This has the advantage of a high utility, especially in the preparation of Pharmaceuticals in the pharmaceutical industry, in biological applications such as fermentation, the cultivation of microorganisms in bioreactors but also in applications where generally high mixing efficiency and quality with high process flexibility are in demand.
- the object is achieved in that the container is provided in its interior in the upper region sealingly connected to the wall of the container with a closed to the mixer plate, the drive shaft enveloping, flexible êtschiauch.
- the sterile disposable container is compactly foldable, storable and inexpensive to manufacture.
- the disposable container consists of a flexible plastic compatible with biopharmaceutical processes on all wetted contact surfaces and can therefore be used for numerous applications. It is particularly advantageous that the container is mounted in a support container. The support tank also gives the required stability to a larger volume of disposable container.
- the container is connected to a flexible inner tube and in the upper region is tightly connected to the wall of the container and in the lower region is conclusively connected to the mixer plate.
- This has the advantage that the entire interior of the mixer is hermetically sealed, no leaks occur and the media to be mixed can not be contaminated.
- all inner contact surfaces, in particular the mixer plate consist of process-compatible, chemically resistant plastics, so that contamination can be reduced.
- the drive shaft is releasably connected both in its upper part with a vibration drive and in the lower region with a plastic mixing plate. This allows the removal of the stem after use and thus allows a rapid change and reduced disposal volume and cost of disposable containers. Also, the attachment of the container on the support container is easy to lock and unlock.
- the inner tube is provided with a removable plastic or steel support tube which protects the inner tube from the oscillating drive shaft. This has the advantage that the flexible plastic can not be overstressed.
- vibration drive and the drive shaft can be installed from below, wherein the mixer plate is also clamped from below.
- FIG. 1 shows the vibromixer according to the invention with a disposable container in a longitudinal section;
- FIG. 2 shows a detailed representation of the detachable connection to the mixer plate in FIG
- the reference numeral 1 represents a vibration drive.
- a drive shaft 2 is connected in a known manner by means of a clamping connection 3 with the vibration drive 1 and fixed with a centering member 4 on the support container 5.
- This attachment 4 - consisting for example of a steel spring, tie cords or a membrane made of elastomers - allows the leadership of the shaft 2 along the longitudinal axis of the support container 4, wherein the oscillating, vertical movement is not hindered.
- the container (disposable container) 6 whose wall is made of flexible plastic, is connected to an inner tube 7 made of flexible plastic and to the container wall by a flange 8 sta rem plastic and a mixer plate 9 made of rigid plastic tightly connected.
- the container 6 is filled via the inner tube 7, filled with the media to be mixed 10, supported by the support container 5 and held in shape and fixed to the flange 8 in the upper region by means of a clamping device 1 1 releasably on the support container 5.
- a hollow support tube 12 made of plastic or metal is inserted through the inner tube 7 and also fixed to the clamping device 11.
- the 5 drive shaft 2 can now also be inserted into the support tube 12 and connected to the mixer plate 9 by a detachable connection 13.
- connection between the mixer plate 9 and the drive shaft 2 is shown.
- the inventive connection mechanism consisting of a
- a mechanism is used, which allows it from outside the inner tube 7, at best from above the container 6, the clamping body 15 to spread through the hollow drive shaft 2 and secure.
- the spreading of the clamping body 15 is done by a plunger 14 wherein two variants for the
- the plunger 14 is provided with an extension which can be fixed by the hollow drive shaft 2 at the upper end outside the inner tube 7, for example by a thread or a screw can be fixed.
- the plunger 14 is in the lower region within the hollow drive shaft 2 with a thread or
- the plunger 14 can be solved in the same way again, with the selected angle of clamping body 15 and the internal geometry of the mixer plate 9 after the loosening of the plunger 14 a
- the selected length of inner tube 7, drive shaft 2 and support tube 12 are chosen so that there is no direct contact between the support tube 12 and mixer plate 9.
- the mixer plate 9 oscillates driven by the vibration drive 1 and the connected drive shaft 2 with an amplitude of 2-5 mm, the support tube
- 35 12 is fixed to the support container 5 and remains without active movement.
- the oscillating movement is therefore absorbed by the inner tube 7 in the vicinity of the mixer plate 9, which can optionally be supported by a damper material 16 made of elastomers or foamed plastics.
- the Function of the support tube 12 is to receive the pressure of the medium to be mixed 10 on the inner tube 7 and to prevent the contact of the same flexible hose to the drive shaft 2 and the contact of the mixer plate 9 to the support tube 12.
