Description

technical field

[0001] The invention relates to a press machine, in particular to a vacuum-belt press filter, which belongs to the technical field of press machinery. Background technique

[0002] At present, the common belt presses in the domestic market mainly include belt press plate presses and belt roll presses. The belt press press mainly relies on the strong pressure of the press plate on the filter belt to dehydrate the material. For example, the Chinese patent No. 90107188.9 discloses a dehydration press, which includes: a pair of moving annular filter belts, the filter belts have two substantially parallel lengths, and the lengths are located between two press plates Each platen acts on the corresponding length of the filter belt through a crawler travel device that includes a series of crawler shoes, and these crawler shoes surround multiple channels perpendicular to the direction of travel of the crawler travel device. The root shafts are hinged to each other, ...
