Can learn whether concrete the elaboration as follows of principle of sideslip of strainer 4: in " background technology ", mention; When the belt sludge dewatering equipment dewaters to mud; The unbalanced meeting of strainer tensile causes the strainer sideslip; Through practice and theoretical analysis, cause that the unbalanced reason of strainer tension force has: the rigidity of roller setting accuracy, roller working accuracy, frame dimensions precision, frame, the skewness of mud on strainer etc.For the good equipment of Installation and Debugging, the uneven major cause of tension force is the skewness of mud, so the strainer sideslip is inevitable.Relation between following surface analysis strainer tension force and the sideslip power: strainer 4 drives running through the driving roll (not shown); Suppose that strainer 4 is in tension force q imbalance like Fig. 5; This moment, a tighter side of driving roll provided more frictional force to strainer; The strainer that can regard a relatively compact side as drives loose relatively strainer and travels forward, and takes out a small cell cube like any point from strainer (except the point on two sidelines), and then the shearing stress direction of cell cube both sides should be as shown in Figure 6.According to shearing stress inter-equal theorem, the complete shearing stress direction of cell cube should be as shown in Figure 7 among Fig. 6.Because of the direction of the shearing stress of the small cell cube of strainer 4 arbitrfary points is all identical with Fig. 7, then the section A-A of Fig. 5 should be identical with Fig. 8 with shearing force direction on the section B-B.When strainer 4 receives load shown in Figure 8, power Q can be regarded as the sideslip power of strainer.Strainer 4 is on the roller in working direction the place ahead, and sideslip power Q overcomes the frictional force of strainer and roller, makes strainer to a tight side sideslip.The deformation form of strainer 4 is as shown in Figure 9 behind the sideslip.Through above-mentioned analysis, the unbalance loading of strainer 4 can cause strainer sideslip power, and the big more sideslip power of unbalance loading is big more.The sideslip reason of the belt water extracter that after debugging, comes into operation causes what the tension force inequality caused by the skewness of mud on strainer basically.Produce principle according to sideslip, can not eradicate the reason of sideslip fully, the best approach that solves sideslip is; Just be formed with also sideslip or when also not forming big sideslip not of sideslip tendency in sideslip power, in time the tension force of strainer implemented balance and correction through anti-deviation device or deviation correcting device, this with the strainer sideslip after; Detect running deviation value; Implement correction according to running deviation value and compare, applicable higher strainer tension force makes that the strainer operation is more steady; The life-span of related components (like strainer, bearing, roller etc.) is longer, and dehydrating effect is also improved.After the tension force generation unbalance loading of strainer 4; The anchorage force of the steady bearing 12 of dehydration roll 3 also must change; Shown in figure 10, suppose that the tension force generation of strainer is unbalanced, the anchorage force of dehydration roll 3 two end axles bearings 10 suffered frames 1 is shown in figure 10; Anchorage force F1 and F2 be equal and opposite in direction when balancing tension, owing to the reason hypothesis F2> of unbalance loading; F1, the difference DELTA F of anchorage force is:
ΔF=F2-F1=?
Q2-q1 in the following formula representes strainer tensile unbalance loading degree, representes that with q then following formula can be rewritten as:
ΔF=F2-F1=
Owing to a, b are fixed, then the difference of dehydration roll 3 two end axles bearings 5 suffered anchorage forces and strainer tensile unbalance loading degree are directly proportional
.Can prove that equally strainer tension force is in equilibrium state and during the amesiality chock of strainer, the anchorage force of two side shaft holders 5 can produce the differential change amount of Δ F equally, the total tension force that can establish strainer during balancing tension is Q, and is shown in figure 11, then draws through deriving:
ΔF=
Δ L=(a-b)/2 wherein
Δ L is the sideslip degree of strainer, so the sideslip degree of the difference of the anchorage force of two end axles bearing 5 and strainer is directly proportional.
Through analyzing under above two kinds of situation, available Δ F controls topworks as measurement signal strainer is rectified a deviation
.Can reach a conclusion to this, the difference DELTA F of chock 5 anchorage forces at dehydration roll 3 two ends and the sideslip power or the running deviation value of strainer are directly proportional, and positive and negative and direction sideslip power of difference DELTA F has corresponding relation.As long as energy measurement goes out the difference DELTA F of chock 5 anchorage forces at dehydration roll 3 two ends, just can grasp the size and Orientation of the sideslip power of strainer.
The differential bridge detection method is adopted in the measurement of the difference DELTA F of
dehydration roll 3 two end axles bearings 5 anchorage forces; As shown in Figure 3, two load sensors under the dehydration roll 3 two end axles bearings 5 10 and a pair of precision resistance 11 are formed differential bridge-type metering circuit by Fig. 3.The diagonal angle AC of electric bridge connects power supply, and voltage of supply is E, and diagonal angle BD connects output terminal, and its output voltage is used U DB Expression.

=?E
Wherein, R3, R4 are a pair of precision resistance, and the resistance value that a pair of load sensor detects when strainer 4 balancing tensions is respectively R1, R2; And R1R4-R2R3=0, so strainer tension force is at equilibrium, or during the original state of electric bridge; Electric bridge is in equilibrium state, output voltage U
DB
=0.Mention above; A pair of load sensor 10 is crushed on respectively between the chock 5 and frame 1 at dehydration roll 3 two ends; This load sensor 10 can detect the anchorage force of 1 pair of chock 6 of frame; And convert this anchorage force to corresponding resistance value, like R1, R2, the position that is used for installation shaft bearing 5 here on the frame 1 can be (like Figure 10, Figure 11) or vertical (like Fig. 2) of level.When strainer tension force is unbalanced; Owing to can think that total tension force of strainer is steady state value; So the suffered load sum of two end axles bearing 5 should remain unchanged; Therefore unbalance loading causes the load increment Δ F that produces opposite sign but equal magnitude on the two end axles bearing 5, and the resistance that the resistance value of the load sensor 10 at two ends also produces opposite sign but equal magnitude increases decrement R, and the absolute value of the increased resistance value Δ R of the big more load sensor of unbalance loading degree is also big more.Output voltage after the unbalance loading is:
U
DB
?=E
=E
Because electric bridge is when strainer is in the balancing tension state, the variate electric bridge is in equilibrium state, so, R1R4-R2R3=0
Then following formula can be rewritten as:
U
DB
?=?E
=
For a specific metering circuit,
Be constant, so, this kind differential bridge metering circuit, measurement signal U
DB
And owing to be complete linear relationship between the differential change value Δ R of the resistance of sensor that strainer tension force unbalance loading causes, and have higher sensitivity.As be designed to equal-arm bridge, and R1=R2=R3=R4=R then, the relation between the differential change value of the output signal of differential bridge and the resistance value of transmitter is:
U
DB
?=
therefore, strainer tensile unbalance loading degree is big more, the output voltage of metering circuit is also big more, when the unbalance loading direction changed, the direction of output voltage also changed.When same strainer balancing tension and strainer position were in the sideslip state, the output voltage of the big more metering circuit of running deviation value was also big more, and when the sideslip direction changed, the direction of output voltage also changed.
To sum up, output voltage signal U
DB
The sideslip power and the sideslip direction that can reflect strainer 4, in the present embodiment, output voltage signal U
DB
Be directly proportional with the sideslip power of strainer 4.Through output voltage signal U
DB
Can not only detect the formation of sideslip power, more importantly be, the output voltage signal U that usefulness and sideslip power are directly proportional
DB
