Abstract
Abstract An apparatus is provided, wherein waste solids are prepared for disposal. The solids are wet pulped into a slurry form, having some solid material therein, with the solids then passing into a trap, whereby larger solid particles that have not been sufficiently reduced in size in the pulper may be collected at the bottom, for carriage by an ejector toward which the particles may optionally receive assistance from a water line, to discharge receptacle. The slurry passes from the trap into another apparatus which further comminutes solids carried by the slurry, for delivery to a press, whereby water is extracted therefrom, with the water then being recycled to the pulper, and with the compacted solids from the press being discharged into the discharge receptacle. A vent is provided, at the outlet of the trap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
Apparatus for preparation of waste solids for disposal comprising means for receiving and pulping solids by abrasion in a liquid medium to a predetermined reduced particle size and having a pulp slurry discharge opening, and trap means having an inlet connected downstream of the discharge opening of said pulping means for receiving a pulp slurry discharged therefrom through a trap means inlet, said trap means having a slurry outlet for discharging a slurry therefrom and being provided with a solids outlet at the bottom thereof for discharge of heavier solids received from said pulping means, including means providing a separate water inlet to said solids outlet of said trap means for assisting removal of solids through said solids outlet.
Claim 2
Dependent Claim
119 words
Apparatus for preparation of waste solids for disposal comprising means for receiving and pulping solids by abrasion in a liquid medium to a predetermined reduced particle size and having a pulp slurry discharge opening, and trap means having an inlet connected downstream of the discharge opening of said pulping means for receiving a pulp slurry discharged therefrom through a trap means inlet, said trap means having a slurry outlet for discharging a slurry therefrom and being provided with a solids outlet at the bottom thereof for discharge of heavier solids received from said pulping means, including means providing a separate water inlet to said solids outlet of said trap means for assisting removal of solids through said solids outlet.
Claim 3
Dependent Claim
119 words
Apparatus for preparation of waste solids for disposal comprising means for receiving and pulping solids by abrasion in a liquid medium to a predetermined reduced particle size and having a pulp slurry discharge opening, and trap means having an inlet connected downstream of the discharge opening of said pulping means for receiving a pulp slurry discharged therefrom through a trap means inlet, said trap means having a slurry outlet for discharging a slurry therefrom and being provided with a solids outlet at the bottom thereof for discharge of heavier solids received from said pulping means, including means providing a separate water inlet to said solids outlet of said trap means for assisting removal of solids through said solids outlet.
Claim 4
Dependent Claim
119 words
Apparatus for preparation of waste solids for disposal comprising means for receiving and pulping solids by abrasion in a liquid medium to a predetermined reduced particle size and having a pulp slurry discharge opening, and trap means having an inlet connected downstream of the discharge opening of said pulping means for receiving a pulp slurry discharged therefrom through a trap means inlet, said trap means having a slurry outlet for discharging a slurry therefrom and being provided with a solids outlet at the bottom thereof for discharge of heavier solids received from said pulping means, including means providing a separate water inlet to said solids outlet of said trap means for assisting removal of solids through said solids outlet.
Claim 5
Dependent Claim
40 words
The apparatus of claim 1, including solids ejector means connected at the solids outlet of said trap means for receiving solid debris in a liquid medium from said trap means and ejecting solid debris thus received from the liquid medium.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1, wherein said solids outlet and said means providing a water inlet comprise means for facilitating lateral displacement of solids from said trap means.
Claim 7
Dependent Claim
15 words
The apparatus of claim 1, wherein said means providing a water inlet comprises venturi means.
Claim 8
Dependent Claim
31 words
The apparatus of claim 1, including a pressing apparatus in the combination connected to said other comminuting apparatus and adapted to receive a slurry therefrom and condense solids from the slurry.
