The invention provides a high-efficiency filter plate cloth washing vehicle, which is used for a filter press, wherein a plurality of filter plates are arranged in the filter press, and filter cloth is fixed on the front surface and the back surface of each filter plate. For convenience of description, in the following examples, the directions are defined as follows: the thickness direction of the filter plate is defined as the front-rear direction, the width direction of the filter plate is defined as the left-right direction, and the height direction of the filter plate is defined as the up-down direction.

As shown in fig. 8 to 10, the filter press comprises a frame 70, a plurality of filter plates supported on the frame 70 side by side in front and rear, and a plate pulling robot 180 mounted on the frame 70 movably in front and rear; the filter plate comprises a filter plate main body 171 and filter plate handles 172 fixed at the left and right sides of the filter plate main body 171; the two plate pulling manipulators 180 are symmetrically arranged left and right, and the two plate pulling manipulators 180 respectively act on the filter plate handles 172 on the left side and the right side of the filter plate to drive the filter plate to move forwards and backwards on the frame 70, and correspondingly carry out plate taking and return resetting.

As shown in fig. 1 and 2, and fig. 8 and 9, the high efficiency filter plate cloth washing vehicle according to the present invention comprises a cloth washing moving frame 10, a cloth washing mechanism 20 mounted on the cloth washing moving frame 10, a telescopic driving source 30, and a telescopic frame 40 in transmission connection with the telescopic driving source 30, wherein the cloth washing moving frame 10 is mounted on a frame 70 of a filter press in a manner of being movable back and forth, the telescopic driving source 30 is mounted on the cloth washing moving frame 10, the telescopic driving source 30 drives the telescopic frame 40 to move in a direction approaching or departing from a plate pulling manipulator 180 in the filter press, the telescopic frame 40 is provided with driving claws 401, and the driving claws 401 are engaged with the plate pulling manipulator 180.

When the filter press does not enter a cloth washing procedure, the high-efficiency filter plate cloth washing vehicle is at an initial position, the telescopic driving source 30 does not act, the telescopic frame 40 is at a position far away from the plate pulling mechanical arm 180, and the driving clamping jaws 401 and the plate pulling mechanical arm 180 are not clamped and separated; in this state, when the plate pulling mechanical arm 180 moves back and forth, the efficient filter plate cloth washing vehicle does not move back and forth along with the plate pulling mechanical arm 180. When the filter press enters a cloth washing procedure, when the plate pulling mechanical arm 180 moves to a high-efficiency filter plate cloth washing vehicle, the telescopic driving source 30 acts to drive the telescopic frame 40 to move towards the direction close to the plate pulling mechanical arm 180, so that the driving claws 401 on the telescopic frame 40 are clamped with the plate pulling mechanical arm 180, as shown in fig. 9; then, in the process that the motor drives the plate pulling mechanical arm 180 to grab the filter plate and return through the speed reducer and the transmission mechanism, the cloth washing moving frame 10 synchronously moves forward and backward along with the plate pulling mechanical arm 180, and the high-efficiency cloth washing vehicle integrally moves forward and backward along with the plate pulling mechanical arm 180 synchronously; when the plate pulling mechanical arm 180 drives the filter plate and the high-efficiency filter plate cloth washing vehicle to move to the preset position, the cloth washing mechanism 20 acts to wash the filter cloth on the front surface and the rear surface of the filter plate.
