Abstract

The invention relates to a vacuum belt press filter, comprising a rack, a vacuum filtration assembly, a press assembly and a filtration belt assembly, wherein the filtration belt assembly comprises an upper filtration belt, a lower filtration belt, and a cleaning device A and a cleaning device B which are used for respectively cleaning the upper filtration belt and the lower filtration belt; the cleaning device B comprises a front guide roller and a rear guide roller on the motion direction of the lower filtration belt, the front guide roller is arranged on the upper face the lower filtration belt, closely contacts the lower filtration belt and enables the lower filtration belt to form a V shape, the rear guide roller is arranged on the lower face of the lower filtration belt and is provided with a plurality of pinpricks, the size of each pinprick is matched with the size of a filtration pore of the filtration belt, and the rear guide roller contacts with the lower filtration belt by the pinpricks; and the cleaning device B is provided with a plurality of spray heads, and the spray heads are distributed on the upper face and the lower face of the lower filtration belt. The vacuum belt press filter of the invention has the advantage of favorable cleaning effect of the filtration belts, and belongs to the technical field of press machines.

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, ...
