The invention discloses a high-stability lifting mechanism which comprises a motor, a screw rod, a frame and a nut movable block. The screw rod is longitudinally arranged, and the motor is fixed to the frame and is connected with and drives the screw rod to rotate. The nut movable block is in threaded fit with the screw rod. The high-stability lifting mechanism is characterized by further comprising a supporting guiding mechanism, the supporting guiding mechanism comprises a guiding trolley fixed to the nut movable block, and a guide plate fixed in the frame and arranged parallel to the screw rod, and two rows of wheels used for clamping the guide plate are arranged on the guide trolley. According to the high-stability lifting mechanism, due to the fact that the supporting guiding mechanism is additionally arranged, the shearing force exerted on the screw rod originally is shared by the nut movable block through the guide plate and the frame, the meshing force between the nut movable block and the screw rod is reduced, the friction resistance between the nut movable block and the screw rod is greatly reduced, and therefore the screw rod can operate more smoothly relative to the nut movable block. Meanwhile, part abrasion is also reduced in long-term use, and the matching precision of the nut movable block and the screw rod and the working stability of the whole mechanism are easily improved.

With utilization of the device and the method, the problem that the cathode plate carries the electrolyte in the tank discharging process in the subsequent section of electrolytic manganese electrolysis is greatly solved. The device and the method can greatly reduce the electrolyte on the cathode plate when the cathode plate is discharged from the tank.

An integrated optimization structure of a stone sawing machine comprises a fixed base. A left side column and a right side column are arranged on the fixed base. A saw frame is movably arranged between the left side column and the right side column. A plurality of saw webs are arranged on the saw frame. A driving device used for driving the saw frame to move up and down in a reciprocating mode is arranged on the left side column and the right side column. The driving device comprises a spindle and a spindle driving motor. A feeding device is further arranged between the left side column and the right side column. The feeding device comprises a feeding table, a feeding table driving motor, a feeding table driving shaft and a driving wheel assembly. The driving wheel assembly is arranged on the feeding table driving shaft and is in transmission connection with the feeding table driving motor. The feeding table and the feeding table driving shaft are connected in a matched mode. The feeding table moves between the left side column and the right side column back and forth in a mode of advancing slowly and retracting rapidly through the cooperation of the feeding table driving motor and the driving wheel assembly.
