During specific work, the pull plate hook 1 and the limiting hook 2 are connected together through the mechanical pull rod 3, and the interlocking interaction function is achieved. When the plate pulling device performs plate pulling action, the plate pulling device firstly moves towards the direction of the filter plate, when the plate pulling device moves to the position of a filter plate handle, the filter plate handle pushes down the plate pulling hook 1 and simultaneously lifts up the limiting hook 2 to stop the plate pulling device from moving forward, the pressure of a motor driving the plate pulling device is increased or the torque of the motor is increased, the control system controls the motor or the motor to move reversely, the tension spring of the limiting hook 2 returns when the plate pulling device moves reversely, and the plate pulling hook 1 is lifted up to pull the filter plate handle to pull the filter plate open.

2. The pulling plate hook 1 and the limiting hook 2 are connected together by the mechanical pull rod 3, the reliability of the mutual action of the pulling plate hook and the limiting hook is good, the actions of lifting and falling down simultaneously can not occur during pulling the plate, and the phenomenon that the plate can not be pulled or pulled can not occur.

3. The limiting hook 2 is always in a state of lying prone by the tension of the tension spring when the plate is pulled, the defect that other plate pulling devices using the tension spring can stand when the plate is pulled is overcome, and the mechanical plate pulling device has the function of pulling a plurality of filter plates without adding a structure on a filter plate handle.

4. The lifting and the falling of the pulling plate hook are realized by the lifting and the pressing of the mechanical pull rod when the pulling plate is finished and started, and the lifting and the falling of the pulling plate hook are not realized by a torsion spring of other pulling plate devices using a tension spring, so that the reliability of the device is improved.

The utility model discloses the mechanical type arm-tie device of pressure filter combines through special design's mechanical type pull rod 3, and two special design's extension spring solve present mechanical arm-tie device's structure complicacy, the unstable problem of work extensively is applicable to various pressure filters.
