Fig. 2 is the structural representation of strainer friction deviation correcting device in the utility model.
Fig. 3 is the structural representation of strainer tensioning deviation correcting device in the utility model.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in the figure: it is that mud medicine blender 1 and the pre-dewatering system of rotary drum thickening machine 2 compositions are placed on composition all-in-ones above the belt squeezing dewatering machine 3 that mud concentrates belt press dewatering all-in-one.Mud and flocculant enter in the container cartridge 12 of mud medicine blender 1 via mud flocculant inlet 13, container cartridge (12) is its agent structure, container cartridge (12) below connects mud flocculant inlet (13), agitating device (11) is equipped with in container cartridge (12) inside, and agitating device (11) top connects drive unit (10).Under the drive of drive unit 10, agitating device 11 stirs it, mud and flocculant fully react, mud forms flco, 21 li of mud grooves in the inflow rotary drum thickener 2, because the rear end part and the horizontal line of mud groove 21 have a little angle, mud and flocculant finally drop on the filter screen 23 in rotary drum 20 outsides by the gravity effect.The back termination drive unit (26) of rotary drum (20), under the effect of drive unit 26, rotary drum 20 in the middle of the frame 25 constantly rotates, rotary drum 20 can with inner push away mud snail revolve 22 and filter screen 23 rotate together, push away mud snail revolve 22 can push mud to front end from the rear end of rotary drum 20, outside flowing out rotary drum 20, fall on the last strainer 38 of belt squeezing dewatering machine 3, in this process, the water of the free state in the process mud of flocculation reaction is under the effect of gravity, the overwhelming majority breaks away from away through filter screens 23, and falling on the last strainer 38 of belt squeezing dewatering machine 3 is the mud of formation flco; The cleaning device 24 at frame 25 tops constantly cleans filter screen 23, guarantees the regeneration of filter screen 23.Under the effect of drive unit 39, two drive rolls 37 can rotate, and under the effect of tensioning apparatus 34, last lower filter belt is tensioned, and system compresses with roller, and two drive rolls, 37 roller rests and lower filter belt 33, the frictional force that goes up between the strainer 38 make the strainer motion.During the utility model work, last strainer 38 can be with flco shape mud to move to the back-end, further slough the water of free state, until entering the wedge shaped area of lower filter belt 33 with last strainer 38 formation, along with strainer 33, the rotation of last strainer 38, mud enters pressed zone, at first pass through tensioning apparatus 34, carry out prepressing, enter the pressed zone that is made of 8 pressure roller 35 again, 8 pressure roller 35 are interspersed, and make the strainer that twines on it S-shaped, 8 pressure roller 35 diameters are descending, make that the cornerite of 8 pressure roller 35 of strainer winding is ascending, thus feasible ascending to the squeeze force of mud, the moisture content of mud is reduced to about 80%, last mud at drive roll 37 from lower filter belt 33, peel off between the last strainer 38, finished whole dehydration.
During the utility model work, lower filter belt 33, last strainer 38 may be amesiality in motion process, at this moment, the cylinder 361 that is positioned at this side in the described friction deviation correcting device 37 will stretch out under the control of gas circuit, make the axis and the lower filter belt 33 of correction roller 360, the direction of motion out of plumb of last strainer 38,360 pairs of lower filter belts 33 of correction roller, the frictional force of last strainer 38 just has one-component on the axis direction of correction roller 360, its direction and strainer 33,38 sideslip directions are opposite, under its effect, lower filter belt 33, last strainer 38 can be got back to the centre position, thereby reaches the purpose of correction.Lower filter belt 33, go up strainer 38 both sides tensioning degrees when different, lower filter belt 33, last strainer 38 meeting sideslips are to the loose side of tensioning, according to this principle, when friction deviation correcting device 37 fails effectively to rectify a deviation, unclamp the retaining mechanism 322 in the tensioning deviation correcting device 32, slide block 321 can be slided on slide rail 320, the position of the slide block 321 of adjusting both sides on slide rail 320 separately, make the tensioning degree of lower filter belt 33, last strainer 38 both sides different, thereby reach the purpose of further correction.
Before the utility model work, the cylinder 341 in the tensioning apparatus 34 shrinks, and drives tensioning plate 340 and upwards rotates tensioning lower filter belt 33 and last strainer 38.
During the utility model work, have in the mesh of filter screen 23, the lower filter belt 33 in the belt squeezing dewatering machine 3 and last strainer 38 in the mud embedding rotary drum thickener 2, High-Pressure Water enters cleaning device 24, and water pipe 240 flows into the filter screen 23 in 241 pairs of rotary drum thickeners 2 of shower nozzle, lower filter belt 33 and the last strainer 38 in the belt squeezing dewatering machine 3 cleans by cleaning.
