Specific embodiment

To keep the purpose, technological means and beneficial effect of the application more clear and complete, with reference to the accompanying drawing to the application Specific embodiment be described.Obviously, described embodiment is only some embodiments of the present application, rather than whole Embodiment.Based on the embodiment in the application, those of ordinary skill in the art are obtained without making creative work The all other embodiment obtained, shall fall in the protection scope of this application.

It as shown in Figure 1-Figure 3, is a kind of a kind of specific implementation of Stacked sludge dewatering machine disclosed in the utility model Mode.In the present embodiment, Stacked sludge dewatering machine includes rack 101, and rack includes bottom plate 101a and two sides and bottom plate Hinged baffle 101b, rack 101 are formed using material well known to those skilled in the art such as welded steel, practical new to this Type is not particularly limited.

Shell 102 is fixedly installed in the rack, the shell forms the main processing of Stacked sludge dewatering machine Cavity, horizontal helical axis 103 is provided in the enclosure interior, and the helical axis includes concentration end 103a and the concentration Hold corresponding dehydration end 103b.Motor is installed outside the shell, motor is mounted on the motor rack of hull outside, Motor and the spiral axis connection, for driving the helical axis to rotate.

Feed inlet is provided at the top of concentration end in the shell, charging and the discharge port of blender are connected by pipeline It connects, after sludge is stirred via blender, the enclosure interior of Stacked sludge dewatering machine is entered by the feed inlet.Described Shell is provided with discharge port close to the side at dehydration end.One or more can be set in discharge port, is preferably provided to three, three The distribution of discharge port circular array；Sludge after treatment passes out to hull outside via the discharge port.A kind of preferred Embodiment in, the bottom of rack is provided with get water bucket, the vertical section of get water bucket is funnel-shaped, and get water bucket is arranged to leak It is bucket-shaped, facilitate the reception of water.

It is staggeredly equipped with fixed ring and travelling ring on the helical axis, spiral helicine add is provided on the travelling ring The screw pitch of strengthening tendons 105, the helical axis gradually becomes smaller from the concentration end to the dehydration end, so that in fixed ring and trip Filter seam between rotating ring gradually becomes smaller from the concentration end to the dehydration end.In a preferred embodiment, move about ring On the screw pitch of spiral helicine reinforcing rib gradually become smaller from the concentration end to the dehydration end.According to the utility model, use The reinforcing rib of aforesaid way setting can reduce the resistance of sludge advance, be conducive to improve efficiency of sludge treatment.

Illustrate that the working principle that spiral shell formula dewaterer is folded in the utility model is located at helical axis when helical axis rotation below External fixed ring and travelling ring makes a relative move, under the effect of gravity, fixed ring and move about ring of the water from relative movement It is filtered out in gap, realizes rapid concentration process.Sludge by concentration is constantly moved along with the rotation of helical axis, along dirt The screw pitch of the direction of advance of mud, helical axis gradually becomes smaller, and the gap between fixed ring and travelling ring is also gradually becoming smaller, helical cavity Volume constantly shrink；In exit under the action of back pressure plate, internal pressure is gradually increased.With the rotation of helical axis, the water of sludge Divide the discharge that is squeezed, filter cake solid content constantly increases, the final continuous dehydration for realizing sludge.The folded spiral shell formula of the utility model is dehydrated Machine can also realize self-cleaning, specifically: when helical axis rotation when, push travelling ring constantly rotate, fixed ring and travelling ring it Between carry out opposite movement, continuous self-cleaning process is realized automatically, so that it is generally existing dexterously to avoid conventional dehydration machine Blockage problem.

In the process of running, sludge is after feed inlet entrance, by helical axis for folded spiral shell formula dewaterer in the utility model It rotates the fixed ring to do relative motion and travelling ring pushes forward sludge, gradually due to the gap between fixed ring and travelling ring It reduces, pressure suffered by sludge also constantly increases therewith, and starts to be dehydrated under differential pressure action, and moisture is from fixed ring and moves about Time of filtration outflow between ring, is completed at the same time self-cleaning process.

Stacked sludge dewatering machine provided by the utility model can not only handle high concentration sludge, can also be to low concentration dirt Mud carries out direct thickening, is applicable in sludge concentration range from 2000mg/L-5000mg/L.Due to can be realized self-cleaning Journey, therefore anti-ability containing greasy dirt is strong, it is easily separated, it does not block.Compared with traditional approach, Stacked sludge dewatering machine is by volume Pressure is dehydrated, and without the large-scale body such as roller, and running speed is low, only 2-4 rpms, therefore it is water-saving, energy saving, make an uproar Sound is low, and average energy consumption is the 1/10, the 1/20 of centrifuge of belt machine, and unit can be only 0.01-0.1kwh/kg-DS afterwards.In addition, Due to the easy obturating element such as no filter-fabric, filter opening in Stacked sludge dewatering machine, operational safety is simple, can carry out journey according to demand Sequence setting, is realized full-automatic unmanned on duty.

The above is only the utility model preferred embodiment, each embodiment in specification is all made of progressive mode Description, the same or similar parts between the embodiments can be referred to each other, the highlights of each of the examples are with other The difference of embodiment.Those of ordinary skill in the art are without creative efforts, it can understand and real It applies.

Although the application is disclosed above in the preferred embodiment, it is not limited to the application.It is any to be familiar with this field Technical staff, in the case where not departing from technical scheme ambit, all using the methods and technical content of the disclosure above Many possible changes and modifications or equivalent example modified to equivalent change are made to technical scheme.Therefore, all It is the content without departing from technical scheme, the technical spirit according to the application is made to the above embodiment any simply to repair Change, equivalent variations and modification, in the range of still falling within technical scheme protection.
