PLATE SHIFTING DEVICE FOR FILTER PRESSES

The purpose of the automatic plate shifter is to move the filter plates (patented sectional emptying), whether they are moved individually or assembled together as a package in order to empty the filter press. Experience has shown that this is done manually on smaller filter presses. With larger plate formats, however, plate shifting is more difficult and requires a plate transport system. The plate shifter is attached to both side rails, which move the filter plates synchronously by means of toothed belts. The system functions hydraulically and is controlled via the PLC control in the control cabinet. For maximum protection, all functional components are mounted in a closed housing, the plate shifting carriage. For safety reasons, the automated plate movement is protected by a light barrier. When reaching into the danger area, the press switches off in accordance with legal requirements.

1) AUTOMATIC PLATE SHIFTING FOR FILTER PRESSES – OVER 800X800MM A MUST

 

For chamber filter presses and membrane filter presses from a plate size of 470x470mm, MSE Filterpressen® offers automatic plate laying. With presses up to a plate size of 800x800mm, the plate can be moved, e.g. during filter cake discharge, without plate shifter – but only if no more than one batch per day is handled. The plate shifter leads through the automatic laying of the filter plates for the emptying of the chambers to a clear facilitation of the handling and/or with larger presses, the moving of the filter plates is only then possible.

 

AUTOMATIC PLATE SHIFTER – SIMPLE AND EFFECTIVE

 

The MSE plate shifter is extremely robust. Thanks to sophisticated technology, the system requires only a few moving parts and is therefore low-wearing. A hydraulic drive ensures low loading of the plate arms. The MSE plate shifting system can be combined with the option of a vibrating device (ΙΙ) for unmanned and automatic operation. These self-contained units can be retrofitted using an MSE PLC control package and can also be easily and individually installed in third-party systems (side beam filter press, overhead beam filter press, etc.). Retrofitting to third-party systems is not uncommon.

2) SECTIONAL EMPTYING BY MEANS OF PATENTED SLIDING TECHNOLOGY

 

The constantly rising cost development forces all companies to find new solutions. MSE filter presses have set new standards early on with their development. The MSE package shift has made it possible to significantly reduce the cycle times of the filter press. The unmanned operation ensures a further cost reduction. Sectional emptying by package shifting has been successfully used in MSE filter presses, for example, in mining, since 2001.

 

PACKAGE SHIFTING REDUCES COSTS WITH FAST EMPTYING OF THE FILTER PRESSES

 

Package shifting, as a method of discharging the filter plates, works with whole plate packages instead of driving individual plates one after the other and freeing them from the filter cake. These are opened and emptied as a unit at the same time. Depending on the size of the filter press, up to 30 plates per unit are simultaneously discharged from the filter cake. Compared to the conventional emptying method, this results in a reduction of the discharge time by up to 70%.

 

Since this process is fully automatic, the personnel costs for press support are also reduced to a minimum. Depending on the application requirements, production can be significantly increased with the same stand space. When designing presses with the same output, the stand space for filtration is smaller and can be better integrated into existing systems. Due to the longer filtration cycle, the upstream and downstream units also run virtually continuously. Here, too, continuous instead of peak performance considerably reduces the construction volume and saves costs. Even when retrofitted under space restrictions, this concept offers advantages. Without major process changes, production can be significantly increased by the new discharge technology.
