PLATE & FRAME FILTER PRESS APPARATUS

Product Description

Plate and frame filter pressesare used in the beverage industry, for example, to clarify intermediateproducts.

A suspension of diatomite andwater (recommended) is prepared in a stirred tank. The stirrer ensures that thesolid remains suspended and does not settle. A pump delivers the suspensioninto the individual separating chambers of the plate and frame filter press.

A separating chamber is formed byone filter frame and two filter plates. The filter plates are grooved andcovered over with filter cloths. The filtrate passes through the filter clothand flows via the grooves in the plates into a collecting pipe.

The filtrate exits the plate andframe filter press through the collecting pipe and is collected in the filtratetank. The solid material is separated off at the filter cloth, where it forms agrowing filter cake. As the filter cake becomes thicker, its flow resistancealso increases. When the separating chamber is full, or a maximum pressuredifference has been reached, the filtration process is ended.

The plates and frames of theplate and frame filter press are pulled apart. The filter cake can be removed.For the next filtration the plates and frames must be pushed back together. Aspindle is used to press them together.

The press forces ensure that thesuspension does not leak from the contact points between the plates and theframes, but is forced through the filter cloth.

The flow rate through the plateand frame filter press is adjusted by a valve. The pressure occurring duringfiltration is indicated on a manometer. The filtrate tank is scaled. This meansa stopwatch can be used to measure the flow rate. An included opacimeter allowsthe solid concentration of the filtrate to be determined. A drying chamber isrecommended for evaluation of the experiments.
