Abstract: A filter cloth washing device for a filter press, wherein wash water is sprayed on filter cloths trained about rollers positioned below the filter plates. In the device, wash water supply pipes having a plurality of spraying nozzles run parallel to the rollers, and have coupling means on at least one of their ends. Each coupling means has an inner diameter larger than the inner diameter of its respective water supply pipe, first and second communication ports and flexible pressure hoses for connecting neighboring coupling means to each other. The connection between neighboring coupling means is such that the first communication port of one coupling means is connected by a flexible pressure hose to the first communication port in another coupling means upstream and its second communication port is connected by another flexible pressure hose to the second communication port of yet another coupling means downstream.

Abstract: A sludge supply device for a single type filter press, wherein a sludge feeding nozzle is fitted in a recess in a side wall of a filter plate, with a filter cloth interposed therebetween, comprising a sludge supply pipe connected to said sludge feeding nozzle and at least two supporting rods carrying said sludge supply pipe and pivotally mounted on a retaining means attached to the side wall of the filter plate, said retaining means, said sludge supply pipe and said at least two supporting rods constituting a parallelogrammatical link mechanism, thereby maintaining said sludge feeding nozzle in a generally constant direction during the movement thereof. This invention facilitates the discharge of cake removed from the filter cloths and ensures smooth travelling of each filter cloth and easy washing thereof.
