Fraccaroli & Balzan S.p.A. can offer a wide range of accessories for filterpresses.
The platform is a supporting structure located all around the filter press, which is used as walkway during the ordinary maintenance operations.
The shaker is a device which, shaking the plates, facilitates the cake drop from the clothes.
The cake blow is used to further decrease the residual moisture of the dewatered cakes. It consists in blowing air through the cakes within the chambers, with the filter press closed.
It is very important to cover the filter press not only to protect it against adverse weather conditions, but also to safeguard the clothes, which can be damaged by the direct sunlight.
The Core Blow is used to expel the residual slurry from the central collector with a blow of compressed air.
The plant for preparing the lime milk is completely automatic. It is normally used for conditioning slurry very diffuclt to dehydrate.
The walking grid is located on top of the drip tray and allow the operator to access the filter press for maintenance operations (for example replacing the clothes, cleaning of plates, etc.) in safety conditions.
The automatic cloth washer is a device which, by means of a high pressure water jet, cleans thoroughly the cloth surface from all filtration wastes.
Conveyor belts or scre can be installed below the filter press to take away the dry cakes dropped at the end of the cycle.
It is possible to use different pumps, on the basis of the type of slurry and the average cycle time. The pumps normally used are centrifugal, single screw and diaphragm. The pressure can vary from 5-6 bar to 16 bar.
All filterpresses are equipped with proper safety devices, in accordance to the current safety norms, to prevent accidents.
In order to keep the slurry inlet pressure under control, it can be used an automatic system constituted by a funnel with diaphragm and analog pressure switch.
This device is used for cooling the seals located in the mechanic transmission of the centrifugal pump.
Level probes (or sonar) are used to determine the flow rate of the drainage water out of the filter press. On the basis of this flow rate, the filter press PLC fix the end of cycle.
The membrane plates filter press are used in processes, where it is necessary to reach a very low moisture degree in the dehydrated cakes. In this case, the pack of plates can be mixed (half recessed plates and half membrane plates) or full membrane.
The filtering clothes are an essential component for the process of liquid/solid separation. The choice of cloth depends on the type of slurry.
Device installed on medium or large size for controlling the process parameters from a remote station.
The drip trays collect the water drained from the filte rpress during the filtration cycle or during the washing cycle of the automatic cloth washer.
The slurry tank is used for storing the slurry to feed the filter press. It is equipped with one or more mixers to keep the slurry homogenized an is sized on the basis of the cycle time of the filter press.
