摘要： A mixer seal assembly for a closable vessel having a dynamic mixer shaft seal in a bore in a vessel flange and a static seal for vessel transport formable by insertion of a disconnected lower portion of a fast connect coupling which is fast to install on the mixer shaft into the flange bore above the dynamic seal. The resulting seal assembly can seal the vessel for over-the-road transport. The dynamic seal includes a circular lip which sealingly engages the surface of the mixer shaft. The static seal includes an O-ring disposed in a first annular groove in the coupling portion. A shaft bushing disposed adjacent to the shaft seal in the flange bore minimizes shaft runout in the shaft seal and permits use of relatively rigid and dry running materials such as fluorocarbon polymer in the shaft seal. In the shut-off position with the coupling portion inserted into the vessel flange, a spring pin mounted in the vessel flange can engage a second annular groove in the coupling portion to lock the coupling portion in the flange bore. In an alternative embodiment for use in retro-fitting existing vessels, the vessel flange of the invention may be configured to sealingly conform to an existing vessel flange.

摘要： An improved immersible magnetically-coupled mixer has rollable bearings readily cleanable by flushing in place and easily removable and replaceable without damage to either the mixer impeller or the bearings. The rollable bearings are resistant to corrosion, capable of running without lubrication, and have low propensity for batch contamination through wear. The rolling and fixed elements of the bearings are impervious to attack by the process materials being mixed, the rollable elements, preferably balls, being formed of a hybrid ceramic such as silicon nitride, and the races being formed of either a nickel-beryllium or cobalt-chromium-tungsten alloy. A mixer impeller having a central bore is rotatably mounted on the rollable bearings on a fixed impeller shaft attached to the inner wall of a vessel at the bottom of the mixing space, which shaft extends through the impeller bore. The impeller contains magnets and is couplable in driving relationship to an external magnetic mixer drive. The impeller bore is larger in diameter than the fixed shaft, and two sets of rollable bearings are disposed between the impeller and the shaft. The bearings are exposed to the liquid in the vessel during agitation, and the impeller provides a continual flow of liquid across the bearing balls and races, preventing formation of stagnant areas of process materials within the mixer assembly and permitting cleaning of all mixer surfaces by flushing.

摘要： A mixer impeller, which is adapted to mix and blend liquids and liquid suspensions in industrial and commmercial applications and is subject to forces which tend to work the impeller loose from attachment with its driving shaft, is secured to the shaft by collars (locking rings) which are threaded on the ends of hubs from which the blades of the impeller extend. In order to secure the attachment of the collars to the hub, a locking key is inserted between the collar and the shaft. The inner periphery of the collars are tapered outwardly away from the shaft. The neck of the locking key has portions which are deflected against these tapered inner peripheries when a pin is inserted through the neck of the locking key. A ramp on the collar mates with a ramp on the key to prevent reverse rotation (working loose) of the collar. The impeller is restrained against axial movement by the collar and against rotational movement by being keyed to the shaft and restricted by the ramp on the collar. Removal of the key for impeller replacement and maintenance is readily accomplished using the ramps on the surfaces of the collars and shoulder of the key which bear against each other. Upon removal of the locking pin, the inside of the neck deflects inwardly and the key is urged out of the collar, when the collar is unscrewed from the hub.

摘要： An improved immersible magnetically-coupled mixer has a plurality of rollable bearing assemblies readily cleanable by flushing in place and easily removable and replaceable without damage to either the mixer impeller or the bearings. The rollable bearings are resistant to corrosion, capable of running without lubrication, and have low propensity for batch contamination through wear. The rolling and fixed elements of the bearings are impervious to attack by the process materials being mixed, the rollable elements, preferably balls, can be formed of a hybrid ceramic such as silicon nitride, and the races can be formed of a nickel-beryllium or cobalt-chromium-tungsten alloy. A mixer impeller having a central bore is rotatably mounted at the upper end of the bore on the rollable bearings on an adapter collar receivable over an end of a fixed impeller shaft attached to the inner wall of a vessel at the bottom of the mixing space, which shaft may be on existing mixer shaft, thus requiring no modification of the shaft to retrofit the impeller assembly. The impeller contains magnets and is couplable in driving relationship to an external magnetic mixer drive. The bearings are exposed to the liquid in the vessel during agitation, and the impeller provides a continual flow of liquid across the bearing balls and races and the adapter collar, preventing formation of stagnant areas of process materials within the mixer assembly and permitting cleaning of all mixer surfaces by flushing.

摘要： An in-place flush-cleanable mixer system for mixing materials in a vessel. The mixer has an impeller connected to a mixer drive shaft, the impeller and shaft being mounted in an assembly which extends through an opening into the vessel and closes that opening. The assembly has a cylindrical hub with bearings which support the shaft and with an open passageway through which the shaft extends out of an open end of the hub. The open passageway is part of a confinement region which is terminated at its outer end by a confinement shell which separates inner and outer rotors of a magnet coupling. The inner rotor is connected to the mixer shaft, and the outer rotor is connected to a drive shaft. There are no dynamic seals which close the confinement region so that the working materials can be present throughout. Included in the assembly is a purge plate coaxially disposed and fitted with a closable port for introduction of flush cleaning materials and with an annular manifold and passages for distribution of the cleaning materials to the open passageway. Abutting assembly components have annular grooves at a periphery of their abutting faces and O-rings disposed and compressed within the grooves to prevent working or cleaning materials from entering the joints between the components and to provide easily flush-cleanable working surfaces at the joints. Bolts and screws within the confinement region are relieved at the periphery of the undersides of their heads and therein have O-rings compressibly retained to prevent entry of materials under the heads.

There are no dynamic seals which close the confinement region so that the aggressive materials can be present therein. In the event that it is desirable that the bearings be replaceable or the confinement region be sterilized, or purged, an expandable elastomeric collar may be disposed either at the end of the hub below the bearings, which may then be mounted in a cartridge in a hub which is removable therefrom, or in a plate spaced from the hub. Purge or pressure release passages may be provided which are opened and through which purging or sterilizing gas is introduced into the confinement region.
