The grouping pulling plate cake discharging mechanism, namely the grouping rapid pulling filter plate cake discharging mechanism, is mainly characterized by comprising a one-time pulling cake discharging mechanism for all filter plates, a two-group pulling cake discharging mechanism for filter plates and a three-group pulling cake discharging mechanism for filter plates; the grouping number of the filter plates directly influences the pulling plate efficiency and the whole machine length; the grouping pulling plate cake discharging mechanism is higher in efficiency than the pulling-out cake discharging mechanism of the filter plates, but the filter press machine body of the same specification is longer, for convenience of explanation, the length of a plurality of filter chambers (total thickness of a plurality of filter plates) is La, the length of a whole machine of the pulling plate is L=1.3 La, and the length of a whole machine of the pulling plate is L=2.3 La; is used for efficiently pulling open the filter plates and realizing gravity cake discharging.

The cake discharging mechanism is formed by pulling all filter plates out at one time, namely the cake discharging mechanism is formed by pulling all filter plates out at one time driven by an ultra-long hydraulic cylinder, all filter plates are connected by chains, the hydraulic cylinders of the filter plate compressing mechanism are shared, and the piston rods of the cylinders are long; the space occupied by the whole filter plate is large by pulling the piston rod of the oil cylinder once by means of shrinkage, and the length L of the whole machine is=2.3 La; the filter press is mainly used for medium-sized and small-sized filter presses, and is described in detail in a filter plate once-pull-open filter press (patent No. CN 201420352704.0).

Two groups of filter plates are pulled to open the cake discharging mechanism, namely a hydraulic cylinder and a single motor are combined to drive the cake discharging mechanism for pulling two groups of filter plates twice, the two groups of filter plates are respectively connected by chains, and the hydraulic cylinder of the filter plate compressing mechanism is shared; the first group of filter plates are pulled out for the first time by means of shrinkage of the piston rod of the oil cylinder, and the second group of filter plates are pulled out for the second time and the first group of filter plates are pulled in by means of a single motor driving transmission chain; after the pulling plate is finished, the distance between the head filter plate and the tail filter plate of the two groups of filter plates is 0.5La smaller than that of the whole filter plate pulled out at one time, and the whole machine length L=1.8La; the filter press is mainly used for medium-sized filter presses, and the details are described in a 'split-open filter press' (patent No. CN 2001249213).
