Definitions

  • Known disintegrators which serve for breaking up and/or cutting up solid substances in waste waterand sewage, above all in the sewage :from municipal sewage plants. have as cutting device a stationary grating and knives rotating over it which are fitted on the blade ends of a radial pump. Because of the greatly variable character of the solid substances, not only must the cutting blades hard and sharp, but also the clearance between the rotating blades and the xed grating must be capable of -being easily and accurately adjusted.
  • adjusting means are provided at least for the rotating part of the cutting device, so that this part can be displaced while the ma chine is rotating, in order to adjust the clearance between the rotating part and the stationary part of the cutting device.
  • Fig. 1 is -a longitudinal section through the disintegrator.
  • Fig. 2 shows the breaking-up knives and the grating. viewed from below.
  • the disintegrator in Fig. 1 with vertical shaft is connected at the bottom through the suction branch l to a sewage system (not shown in the drawing), where solid substances are carried in the liquid. In lparticular in waste water from town sewers, all kinds of substances are carried along with the liquid, and this may 4under certain circumstances choke the pumps handling the sewage.
  • a sewage system not shown in the drawing
  • On the suction branch I is set the casing 2 of the disintegrator with the delivery branch 3 to which a pipe is connected leading the brokenup solid substances to a delivery pump, a settling tank or such like.
  • a knifecross 5 which is -provided with several knives and is held firmly by means of the nut 6. A-bove the knife-cross 5 the grating 1 with slit-shaped passages B is provided.
  • the shaft 4 is supported in the 'bearing 9 of the casing 2 and rendered tight at its upper end by means of the stuing-box I.
  • the step bearing I3 is provided, which l-s fixed to the shaft by means of the key I 4 and the nut I5 and can be axially displaced.
  • the step bearing I3 is held axially in the step-bearing casing I6 between the ring Il on the cover I8 and the bottom I9 of the casing.
  • the flange 20 is provided with a screw thread 2 I, which engages the counter screw thread within the hand wheel 22.
  • the step-bearing casing I6 is led and held axially by means of the studfbolts 23 which project through the ange 20 and the cover I8.
  • the cover I8 is fixed to the flange 2D of the casing I6 by means of the stud-bolts 24.
  • the shaft is rendered oil-tight by means of the packing pieces 25.
  • a coupling (not shown in the drawing) is keyed; this couples the shaft 4 to the driving motor (also not shown) for the cutting knives 5.
  • the counter knife 21, which works together with the underside of the knife-cross 5, is xed to the displaceably-carried supporting member, the cylindrically-shaped piston 28, by means of a screw or bolt 29.
  • the supporting member 28 is fixed to the suction branch I by means of the nuts 30 for adjusting the counter knife 21.
  • passages 32, 33 are provided in the bearing 9 and are connected to a water pipe (not shown).
  • the passages 32, 33 lead water under pressure to the annular sl-ot 34, from which it is led through the nut 5 and the grating I to the knives of the knife-cross 5 and serves to cleam them.
  • the introduction of Water under pressure through the slot 34 while the machine is working prevents the bearing 9 from becoming dirty.
  • the hand wheel 22 is then turned in the contrary direction, thus drawing the knife-cross 5 towards the grating 1.
  • This loosening and tightening up again is preferably repeated several times one after the other, in order to remove all impurities which occasionally adhere firmly as a hard deposit on the knife edges.
  • the clearance between the knife-cross 5 and the grating 'l can be adjusted again.
  • the new setting of the hand wheel 22 can be read on the scale 35 on the casing I I by means of a pointer 36 at the moment when the knife-cross 5 touches the grating, and then by turning the hand wheel 22 back through a certain distance along the scale 35, a clearance of, for instance 0.1 mm., can be accurately adjusted.
  • of the stud-bolts 23 are again tightened firmly and the clearance adjusted will remain unchanged in service, even under great vibrations.
  • the counter-knife 21 is newly set with respect to the knife-cross 5.
  • the nuts 30 are loosened and the supporting member 28 is pushed backwards and forwards several times in order that any impurities on the counter knife 21 may be removed by the rotating knife-cross 5.
  • the piston 28 is pushed in so far that the counter knife 21 touches the underside of the knife cross 5, after which the piston 28 is pulled back through a distance equal to the required clearance and then fixed in this position by means of the nuts 30.
  • the amount of the clearance can be accurately measured at the suction branch I between the flange 3'1 of the piston 28 and the branch piece 38 on the suction branch I.
  • the grating l has to be ground from time to time on the side of the cutting plane 39 in order to improve the cutting action of the disintegrator, it will be advisable to provide insert rings 40 on the upper side of the grating 1, between it and the casing 2, in order to be able to keep the cutting plane 39 as far as possible at the same position in 4 ment and of the reading on the scale I5 is improved.
  • the breaking-up of the solid substances in the sewage accelerates fermentation in the fermenting chambers, so that the time required for fermentation depends to a large degree on the accurate setting of the cutting device. Because of the great differences in the kinds of sewage sub, stances, as well as in their quantities, it is very important that the setting can be e'ected while the rotating cutting knives are in service.
  • the adjusting of the step-bearing casing I6 with respect to the casing 2 of the disintegrator could also be effected by means of a lever, an eccentric, etc.
  • a bearing structure permitting the axial adjustment of a rotating shaft
  • the combination including a shaft, a bearing seeve assembly in which said shaft is journaled and held against relative axial movement in either direction, a stationary frame structure in which said bearing assembly is mounted slidable axially, an internally threaded adjusting member engaging external threads on said bearingassembly, and adjustable retaining means fixing said bearing assembly against rotation in said frame and adjustably limiting its axial movement relative there to without engaging said adjusting member.
  • a disintegrator device which includes in combination a stationary frame structure, a bearing sleeve assembly mounted slidable axially inv said frame structure, a shaft journaled in said bearing assembly and held against relative axialn movement in either direction, a rotating shearing member carried by said shaft, a stationary shearing member carried by said frame structure adjacent to and cooperating with said rotating member, and adjusting means acting on said shaft in an axial direction to adjust the shearing clearance between said rotating member and said stationary member, which adjusting means includes an internally threaded adjusting member engaging external threads on said bearing assembly, and adjustable retaining means fixing said bearing assembly against rotation in said frame and adjustably limiting its axial movement relative thereto without engaging said adjusting member.
  • a disintegrator which includes a casing body and cutting apparatus within said casing body, said cutting apparatus including a stationary part, a rotating part and adjustment means by which sid rotating part can be moved during .i rotation for the adjustment of the clearance bethe casing 2.
  • the adjusting screwthread 2I can have a smaller pitch, so that for one and the same clearance the adjusting angle through which the hand wheel 22 turns is greater, and consequently the accuracy of the adjust- In the case of smaller amounts of adtween it and said stationary apparatus, the improvement in which said adjustment means include -a bearing housing, means fixing said housing against rotation in said casing body, a bearing journalling said .rotating part in said housing and fixing said rotating part against axial movement relative to said housing, movement producing means engaging said bearing housing and said casing body for producing relative movement parallel to the axis of said rotating part between said housing and said casing body, and adjustable movement restraining means operatively interconnecting said bearing housing and said casing body whereby the permissible relative movement between said bearing housing and said casing body in the direction which reduces said clearance is positively limited.
