The problems of paper belt filter in use

in the process of chemical production, the paper belt filter needs to replace the residual filtrate in the filter cake with the lotion containing no impurities, that is, to wash the filter cake.
the purpose of washing filter cake of paper belt filter is to remove the residual solute in the filter cake, to improve the purity of the filter cake, or to recover the valuable liquor trapped in the filter cake.
the problems of filter in use
1.paper belt filter is actually a set of water tank with filter device, how to conveniently clean the water tank is a problem.
2.at the same time, large flow filter adopts flat screen paper belt filter, structural strength must pay attention to.
3. if the impurities in the liquid are more and the proportion is larger, the filter paper is prone to sag and rupture.
4.flat screen paper belt filter is limited by the structure, the liquid pool is shallow.if the liquid has a certain viscosity, or there are more bubbles in the liquid, or the liquid level switch adheres to the impurity alarm failure will produce the phenomenon of liquid overflow.
5.the slagging end design does not pay attention to there will be a drip phenomenon.
6.filter paper is an important accessory, is also consumable, in order to reduce the consumption of filter paper.it is generally recommended to add a magnetic separator to the paper tape filter, or adopt other forms.
