  • Patent number: 8721166
    Abstract: A method of evacuating a refinery tank containing waste with solid constituents is disclosed. The method includes inserting an agitator on a boom through a first opening on a side of the refinery tank and agitating waste in a first area of the refinery tank to cause the waste in the first area to have a first viscosity lower than a second viscosity of waste in a second area at a periphery of the first area. The method further includes removing agitated waste from the first area while maintaining the waste of the second viscosity in the second area, thereby forming a safe room in the refinery tank. The method also includes expanding the first opening toward the floor of the safe room to enable entry of a movable excavator into the safe room of the refinery tank and removing waste of the second viscosity from the second area of the refinery tank.

  • Patent number: 7237778
    Abstract: The invention is a shut-off seal assembly for use with the drive assembly of fluid-containing vessels. The shut-off seal assembly first locks the seal carrier of the drive assembly in place so that it may not rotate in a clockwise or a counter-clockwise direction. The seal carrier includes a pair of notches into which a pawl may be fitted preventing seal carrier rotation. The seal carrier surrounds a sleeve which includes a plurality of slots. A backwards rotation of the drive shaft causes drive pins to slide in the angled slots, thereby causing the seal element to move forward and create a seal between the drive assembly and the vessel.

  • Patent number: 6616326
    Abstract: An improved shaft sealing assembly (18) for use with an elongated, axially rotatable shaft (14) typically forming a part of a blender (10) or similar device is provided, which permits rapid, easy seal repair without the need for complete breakdown of the blender (10). The assembly (18) includes a tubular sleeve adapted to be disposed about the shaft (14) at the region of a shaft/blender wall interface, with an annular sealing body (42) disposed about the sleeve (40) in a sealing position and supporting a seal (66) which engages the sleeve (40) at a first sealing location (66a) thereon. A lock device (48) operably to maintain the sealing body (42) in its sealing position is provided, and the sleeve (40) is selectively movable relative to shaft (14) and sealing body (42) so as to change the sealing location from the first location (66a) to a second, different sealing location (66b). The sleeve 40 can also be easily replaced if desired.

  • Patent number: 6572261
    Abstract: An agitator assembly for mounting in a wall of a storage tank that includes a body having a rotatable shaft extending therethrough. The body includes a duct having a diameter that is larger than the diameter of the shaft to allow passage of a fluid therebetween. An impeller is secured to one end of the shaft and a collar is secured to the other end. A bushing is provided between the body and the shaft and allows passage of a fluid during a cleaning cycle. A motor assembly is attached to the shaft and provides power for rotation of the shaft. A resilient member is provided over the shaft between the motor assembly and collar to control axial movement of the shaft. During a cleaning cycle, fluid pressure overcomes the biasing force of the compressible member permitting the fluid to escape the body to effectively clean the impeller.

  • Patent number: 6568844
    Abstract: The present invention relates to a device for treatment of material in a vessel, particularly for dispersion or homogenization of liquids, or for suspension of solids in liquids. The device comprises a treatment element that is rotationally mounted in the vessel and that has an essentially tubular configuration comprising two ends. The jacket of the treatment element has a plurality of cuts formed with sharp edges, which may be drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material. The shearing forces produce the desired treatment in the vessel.

  • Publication number: 20020172092
    Abstract: In one aspect, a mixing arrangement is provided for a tank mixing system which includes a tank defined by a side wall, a bottom and a top, the top including at least one opening therethrough. The arrangement includes a non-rotating elongated arm extending through the opening in the top of the tank, the arm pivoted for movement about a pivot axis; an impeller positioned on the arm for movement therewith and within the tank, the impeller moving back and forth along an arcuate path within the tank as the arm pivots back and forth about the pivot axis. In another aspect, a ball-and-socket assembly is positioned above the top of the tank and is movable along a curved path to mope an impeller in a curved path within the tank.

  • Patent number: 6193409
    Abstract: An agitator assembly includes a dynamic or rotary seal which has a pusher for mechanically separating the seal members as the agitator is moved into a clean-in-place orientation. There are three embodiments of the invention, with all embodiments including a pusher mounted on the drive shaft so that as the seal is moved with respect to the drive shaft by either moving the drive shaft or the seal, the pusher engages one of the seal members to mechanically separate it from the other seal member. The pusher preferably comprises a shaft mounted “O” ring in two of the embodiments, and a ring shaped and tapered structure in the other embodiment. The embodiments provide for a seal that has springs located within the tank, a seal with an elastomer to provide the spring sealing force, and a seal with springs located outside the tank.

  • Patent number: 5735603
    Abstract: A horizontal mixer for mixing and processing materials includes a horizontally disposed mixing chamber and an elongated rotatable mixing shaft extending longitudinally through the chamber. The drive apparatus is coupled to a drive of the mixing shaft to rotate the shaft and mix material placed in the chamber. A stub end of the shaft has a bearing portion extending through an end wall of the chamber opposite the drive end of the shaft. The bearing portion engages a sleeve bearing which is operable for rotatably supporting the stub end proximate the end wall opening. A sealing shroud is coupled proximate the sleeve bearing and covers an outer portion of the shaft stub end. A static shroud seal is coupled with the sealing shroud at an interface between the shroud and the sleeve bearing. The static shroud is maintained out of direct contact with the rotatable shaft stub end.

  • Patent number: 5711600
    Abstract: Cellulose pulp is discharged from the dilution zone of a high consistency pulp tower at a substantially even volume flow and a substantially steady pulp consistency by mounting a particular parting member within a bottom portion of the tower. The parting member is constructed so as to define a first cross-sectional area between it and the tower side wall which is smaller than a second cross-sectional area below the parting member, in the dilution zone. The parting member may comprise a cone, cone frustum, pyramid, or pyramid frustum mounted substantially concentrically with the tower axis. The first cross-sectional area is at most 95% of a second cross-sectional flow area in the dilution zone, and typically about 90% or less. A ring may extend inwardly from the side wall at the parting member and define the first cross-sectional flow area with the parting member. Alternatively the parting member may itself comprise a ring having a substantially triangular (e.g.
