The filter plate comprises the filter chamber self-locking device, and the filter chamber self-locking device is uniformly distributed around the filter plate.
Further, each filter chamber uses 8 filter chamber self-locking devices.
The beneficial effects of the invention are as follows: when the filter chamber is closed, the self-locking shaft of the filter chamber self-locking device is pressed down into the groove of the locking block by the spring along with the forward movement of the self-locking plate to hang the self-locking block, and the movable plate of the auxiliary hydraulic system locking the filter chamber is prevented from retreating. As the filter chamber moving plate moves forward, the distance between the filter chamber moving plate and the fixed plate is gradually reduced, and the self-locking shaft arranged in the self-locking plate also moves forward along with the filter chamber moving plate and is lifted along the inclined plane of the self-locking block. When the press filtration of the dehydrator is finished, the return pins in the self-locking shaft and the self-locking shaft are lifted to the lower edges of the baffle grooves on the two sides along the inclined planes of the self-locking blocks, the return pins arranged on the two sides in the self-locking shaft are ejected out under the action of the return springs and enter the grooves of the baffle to be clamped, and the downward movement of the self-locking shaft is limited. After a working process of the filter press is finished, the self-locking plate welded on the movable plate retreats with the self-locking shaft, when the self-locking plate retreats to the center head position of the baffle groove, the inclined surface of the baffle groove pushes the return pin in the self-locking shaft away from the groove, at the moment, the return pin loses the effect of clamping the self-locking shaft, the self-locking shaft is pressed down along the circular groove of the self-locking plate under the action of the spring arranged in the pressing shaft, the whole self-locking device is reset to the initial position, and a new cycle of work can be started.
