The filter cloth deviation rectifying process of the filter cloth deviation rectifying mechanism 4 is further explained as follows:
as shown in FIG. 10, the upper filter cloth 102 passes between the upper deflection roller 4-1 and the lower deflection roller 4-2 and is wound under the mud jacking roller 4-12. In the mud distributing or mud discharging process of the filter press, the filter cloth can move along the length direction of the filter cloth, if the filter cloth is offset when moving, the filter cloth can trigger a displacement sensor 4-17 positioned on one side of the filter cloth, the displacement sensor which detects the filter cloth can send a detection signal, a filter cloth deviation correction driving unit starts to act according to the detection signal, one end of an upper deviation correcting roller and one end of a lower deviation correcting roller are controlled to ascend, the other end of the upper deviation correcting roller and the lower deviation correcting roller descend, and the filter cloth can move towards the end with the height of the deviation correcting roller to correct the deviation.
For example, referring to fig. 9, if the filter cloth is biased to the right, the filter cloth triggers the displacement sensor 4-17 located on the right side, the displacement sensor 4-17 sends a detection signal, then the first filter cloth deviation-rectifying driving unit 4-4 controls the first deviation-rectifying roller mounting frame 4-3 to move downwards, and the second filter cloth deviation-rectifying driving unit 4-6 controls the second deviation-rectifying roller mounting frame 4-5 to move upwards, so that the right ends of the upper deviation-rectifying roller 4-1 and the lower deviation-rectifying roller 4-2 fall and the left ends of the upper deviation-rectifying roller and the lower deviation-rectifying roller rise, and the deviation rectification of the filter cloth can be rapidly realized. If the filter cloth is biased to the left, the above operation is reversed.
Compared with a single-roller deviation rectifying structure, the upper deviation rectifying roller 4-1 and the lower deviation rectifying roller 4-2 can move relatively in the vertical direction, and when cloth is fed, the gap between the upper deviation rectifying roller 4-1 and the lower deviation rectifying roller 4-2 can be increased, so that the forward resistance of the filter cloth is reduced; when cloth is collected and mud is discharged, the gap between the upper rectification roller 4-1 and the lower rectification roller 4-2 can be reduced, the upper filter cloth 102 is clamped between the upper rectification roller 4-1 and the lower rectification roller 4-2 and clamped tightly, tension is generated on the filter cloth, the filter cloth is leveled, and wrinkling and unevenness of the filter cloth are prevented.
The filter press has double deviation rectifying functions, the filter cloth deviation rectifying mechanism and the cloth rolling mechanism can rectify the filter cloth in the working process of the filter press, so that the filter cloth can not be biased in the mud distributing and discharging operation processes, the sludge leakage in the mud distributing and filter pressing processes is avoided, and meanwhile, under the action of the feeding, deviation measuring mechanism and the cloth rolling mechanism, the filter cloth is not biased on the cloth rolling roller, the filter cloth rolls on the cloth rolling roller are kept in order, and the cloth collecting and discharging are convenient. And the filter cloth deviation rectifying mechanism, the winding feeding deviation measuring mechanism and the cloth winding mechanism can generate tension on the filter cloth, so that the filter cloth is ensured to be flat in the working process, and cloth discharging and mud collecting are facilitated. In the preferred technical scheme, the adjustable thickness of the sludge cake can be realized by adjusting the height of the sludge pressing roller, the operation is stable, the automatic operation can be realized, and the labor cost is reduced. And through the counting assembly, the length of the cloth mud of the filter cloth is equal to the length of the cloth of the filter cloth after the filter cloth completes filter pressing, so that the subsequent continuous normal work of the filter cloth of the filter press is ensured.
In the foregoing embodiment, the filter cloth is taken as an example to explain each component, and the above components can also be applied to the lower filter cloth to realize double deviation correction of the lower filter cloth, receive cloth and unload mud, and the lengths of the cloth received and released by the lower filter cloth are equal, so that the manufacturing cost and difficulty of the cloth stacking filter press can be reduced.
