The difference between belt filter press and vacuum belt filter

Vacuum belt filter is used for materials that are easily dehydrated, while vacuum belt filter press presses are used in the process of extrusion, for relatively difficult dehydration. So, what is the difference between belt filter press and vacuum belt filter?
First of all, we first analyze their working principle. Vacuum belt filter is a simple way to rely on the natural pressure of the liquid in the mixture or other natural external force, so that the liquid filter in the filter cloth under the conditions of interception, through the filter cloth, while the solid was intercepted In the filter cloth media, so that the filter to achieve the purpose of the work.
Belt filter press is in the external force of the conditions, while adding a device itself to provide a pressure, but also on the mixture. Filter press on its own pressure system, resulting in a source of pressure in the system through the clever design of the filter, the pressure will be passed to the filter plate, so that in the filter, the mixture also increased a strong external force, Very good to improve the capacity of the box filter press. Filter and the working principle of the filter is the difference between the conditions of the filter.
Secondly, we look at the design of the respective filter room. Vacuum belt filter filter chamber design is not very harsh, and its filter cloth and single-sided contact with the mixture. Belt filter press filter design is through a number of filter plate under the action of pressure, the formation of the corresponding filter cavity, and each filter can be placed in the middle of the filter cloth, that is, a filter cavity is equivalent to A filter. So the filter press filter room is a row of the filter plate neatly arranged, the middle folder filter cloth, while the need for sealing conditions.
