The working principle of the utility model are as follows: sludge is entered in dewatering unit 4 by sludge import 15, and sludge import 15 is arranged On the cylinder 1 of 14 side of stirring motor, the lower part of sludge import 15 is corresponding with dehydration tube 41, and dehydration tube 41 is upper and lower opening Cylinder, sludge be dehydrated in dehydration tube 41 after by sludge intercommunicating pore 12 enter drying unit 5 in is dried, after drying by Sludge outlet pipeline 56, which enters to press dry to press dry in unit 2, to be discharged as after mud cake by cake outlet 28；Dehydration tube 41 changes Traditional horizontal type structure using the high vertical structure of dehydration efficiency can not only improve dehydration efficiency, additionally it is possible to make to stir It mixes motor 14 while providing power for drying unit, sludge, which enters after dehydration tube 41, to be fallen into first in tilting slide plate 46, is being rotated And constantly moved to next tilting slide plate 46 under the action of self power, dehydration efficiency can not only be improved during movement The tilt angle that can also prevent blocking sieve pore 45(tilting slide plate 46, can effectively block sludge and contact with sieve pore 45, work as water With partial impurities from the tilting slide plate 46 on opposite to when sieve pore movement, water and partial impurities can directly be had since strength is larger Sieve pore 45 is taken out of, even if biggish impurity can not be discharged by sieve pore 45, then is capable of in the tilting slide plate 46 of bottom under the washing away of water Converge with sludge), while the setting of tilting slide plate 46 can effectively improve residence time of the sludge in dewatering unit；Water is by sieving Hole 45 collects in the angle of cylinder 1 and partition 11 by partition 11 after being discharged, be discharged by the first water outlet 13；After dehydration Sludge by sludge intercommunicating pore 12 enter drying unit in dried, rectangle framework 52 be hollow structure, stirring driven shaft 44 lower part is hollow structure, and waste heat feed channel 3 enters the lower part of stirring driven shaft 44 by intake valve 7, then driven by stirring The lower part of axis 44 enters in rectangle framework 52, is finally entered in drying unit 5 by venthole 54, the gas in drying unit 5 And the water of evaporation is discharged by sludge intercommunicating pore 12 and sludge import 15, in the stirring of the first agitating unit and the second agitating unit In the process, screw auger blade 51 can make the more uniform of sludge agitation, to create condition for thermally equivalent；Rectangle Framework 52 itself and venthole 54 can heat sludge, which overcomes lacking for traditional jacket type heating method It is sunken that (jacket type heating method is that collet is arranged on the outside of cylinder, and heat medium is passed through in collet, and the heat of the heating method can It being spread from outside, heat utilization rate is low, and especially the sludge close from 1 inner wall of cylinder easily drying sticks on barrel in this industry, The operation later period defect that seriously affects heat exchange efficiency, and easily cause sludge quantum of output few), in venthole 54 pressure of waste hot gas compared with The inner wall of cylinder 1 can be purged greatly, several blade inserts 53 on the outside frame of rectangle framework 52 can be timely Barrel is cleared up, the blade insert 53 of the following frame bottom of rectangle framework 52 clears up 1 lower surface of cylinder same When can prevent the mouth blocking at the top of sludge outlet pipeline 56；Entered after drying by sludge outlet pipeline 56 and is pressed dry in unit 2, liquid Compressing cylinder 26 pushes pressing plate 27 mobile to the other side for pressing dry shell 21, in moving process a small amount of moisture can by upper sieve plate 22, Filter cloth 23 and lower sieve plate 24 enter in sump 29, and are discharged by the second water outlet 25；Door is opened after compression process, it will Mud cake is by cake outlet 28.It should be strongly noted that by testing bottom and horizontal plane when tilting slide plate 46 repeatedly Between the angle effect that prevents when being 30 °~45 ° blocking sieve pore 45 from blocking it is best.The internal diameter of the sludge intercommunicating pore 12 is equal to The internal diameter of dehydration tube 41；The bottom of dehydration tube 41 is fitted closely with sludge intercommunicating pore 12, and gasket, waste heat are equipped between both Gas can carry out prebake to the sludge of 41 lower part of dehydration tube during rising.Preferably, cylinder 1 described in the utility model Lower part is equipped with several barrel support brackets, makes to press dry the bottom that cylinder 1 is arranged in unit 2, not only facilitates sludge outlet pipeline 56 discharge sludge, additionally it is possible to effectively saving space；It should be noted that waste heat feed channel 3 and stirring are driven in the utility model Sealing device is attached and installed additional between the lower part of axis 44 by way of clamping, i.e. stirring driven shaft 44 rotates, waste hot gas Pipeline 3 does not rotate；Above-mentioned relevant apparatus can be purchased directly on the market, and structure repeats no more.
