A solid waste material comminuting system havingaanelectric 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 stackscomprisecomprisesa central shaft journaled for rotation and aseal-bearingassembly/module at each end of the central shafts. Eachbearingassembly/module comprises an end housing, and a pair of insertable pre-assembledseal-bearingelements/assemblies mountable in each of said end housings. Oneseal-bearingelement/assembly has a thru-hole for journaling a first shaft for rotation and a secondseal-bearingelement/assembly has a thru-hole for journaling a second shaft for rotation.

Seal bearing assembly for use in a solid waste comminutor

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.

Integrated diverter and waste comminutor

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 screen unit is mounted to the frame. It may be a single screen or dual screens. The screen unit comprises a cylindrical screen rotating on a screen shaft having a screen shaft mounted on bottom housing of the frame and supporting the cylindrical screen. A drive assembly operable couples the drive mechanism to the screen shaft to rotate the cylindrical screen as the cutter assembly rotates. In operation with the screen unit positioned adjacent to the grinder unit it diverts solids in the effluent stream toward the grinder unit for size reduction. An auger-screen may be placed downstream for removal of large solids after size reduction.

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. The device employs side rails having interleaved and smooth portions to guide solids to the cutter stack and to accelerate the flow of fluid around the outside of the cutters.

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. Multiple screen units and multiple grinder units may be employed with the multiple screen units in stacked array, in end overlapping position, and with the endless screens driven to deflect solids towards one or more grinder units offset below the most downstream screen unit of the array.
