Abstract: An integrated system for diverting and reducing the size of waste materials in an effluent stream comprising a frame having a bottom housing and a top housing and mountable in the stream. A grinder unit is mounted to the frame bottom housing and comprises a cutter assembly positioned in the stream and a drive mechanism coupled to the cutter assembly to rotate the cutter assembly. The drive mechanism may be electric or hydraulic. A diverter unit is mounted to the frame. It may be a single diverter or dual diverters. The diverter unit comprises a cylindrical drum rotating on a stub shaft. It may also be a helical coil. A drive assembly operably couples the drive mechanism to the drum shaft to rotate the cylindrical drum as the cutter assembly rotates. In operation the diverter unit is positioned side by side to the grinder unit to diverts solids in the effluent stream toward the grinder unit for size reduction. Side rails are employed for flow control around both the diverter unit and the grinder unit.

Abstract: A solid waste material comminuting system having a electric motor for providing rotary motion, a pair of cutter stacks with cutter elements of one stack interleaved with cutter elements of the other, and gear means to transmit the rotary motion of the electric motor to counter-rotate cutter elements of one stack with cutter elements of the other. Each of the cutter stacks comprise a central shaft journaled for rotation and a bearing module at each end of the central shafts. Each bearing module comprises an end housing, and a pair of insertable preassembled bearing assemblies mountable in each of said end housings. One bearing assembly has a thru-hole for journaling a first shaft for rotation and a second bearing assembly has a thru-hole for journaling a second shaft for rotation. The housing has an inspection port at the top to allow for tightening of the cutter stack.

Abstract: A solid waste handling system for screening and grinding solids entrained in an influent liquid stream flowing within a chute between laterally spaced vertical sidewalls utilizes at least one solids diverter horizontal rotating screen unit fixedly mounted within the chute and at an angle to the influent liquid stream with an endless loop open mesh screen mounted for rotation on a frame assembly such that one upstream face of the screen is vertical and moves horizontally across the stream in a direction towards the downstream offset grinder unit. The grinder unit has a housing with an upstream facing inlet port and mounts internally within the housing stacked interengaging shredding members for rotation about their axes in the path of flow of the solids bearing influent. Motors mounted to the units above the influent liquid stream level drive the screen and shredding members of respective units.

Abstract: An annular elastomeric seal wedge of diamond shaped radial cross section under axial compression has opposite axial ends fitted within V-shaped cross section annular grooves within a radially projected shoulder of a bushing of a fluid pressure assisted rotary shaft seal and a similar V-shaped annular groove within the axial end face of the rotating seal race. A radial groove is formed within the side of the annular elastomeric seal wedge remote from the outside of the rotary shaft seal which receives an annular metal wave spring having axial undulations for axially biasing the rotating seal race in contact with the end face of a static seal race to form the dynamic shaft seal and for maintaining the positive pressure seal between the ends of the axial ends of the diamond shaped annular elastomeric seal wedge across the gap between the bushing radially projecting shoulder and the facing end of the rotating seal race.

Abstract: Two interacting stacks of peripheral overlapping shredding members of disk form are mounted on substantially parallel shafts and positioned transversely to the direction of waste material passing through a comminutor casing. The casing opens upstream and downstream side for introducing liquid borne waste to the chamber and for discharging the comminuted waste therefrom after shredding, respectively. The casing is closed off by a pair of imperforate side rails, each side rail is slotted to form a series of inwardly projecting planar fingers having front edges of circular arc form facing the periphery of the rotating cutting element disks and having a radius larger than the radius of the disks and being spaced slightly therefrom. The array of fingers extend over the complete height of the stack shredding members. This facilitates greater flow of the liquid through the comminution chamber via slots between the fingers, carrying fine solids to enhance comminution.

Abstract: A replaceable wear sleeve cartridge fixedly mounted to a housing bore carries internally the fixed race of an anti-friction bearing and a static seal race. The wear sleeve cartridge defines with a labyrinth preseal bushing fixed to the shaft, the basic elements of a labyrinth preseal and additionally resiliently couples through a seal wedge, a rotating seal race whose end face is both fluid pressure and resiliently biased against the end face of the annular static seal race.

Abstract: A neoprene boot fixes a static race of a rotary shaft seal within a housing bore. An annular rotating race bears a carbon insert laterally mated to the radial face of the static race. A bushing borne by the rotating shaft supports a neoprene seal sleeve of inverted T-shape configuration including a flexible lip reinforced with a steel ring which is pressed by distortion and fluid pressure against a rotating sleeve, to which the sleeve base is locked. The rotating race presses against the static race to maintain a high integrity fluid tight seal between the rotating shaft and the fixed housing.
