Problems solved by technology

[0004] However, in this technical solution, the direct separation method is adopted when the filter cake and the filter plate are separated, but most of the existing filter plates are provided with a plurality of protrusions for fixing the filter cloth. The direct separation method of filter cake and filter plate will cause the separation mechanism to cut into the raised part, thereby damaging the filter plate. In addition, the existing filter cake separation filter plate and filter plate cleaning are divided into two different equipment, Unable to perform integrated operation, resulting in the need to re-clean the entire row of filter plates after the entire row of filter cakes are separated from the treatment, not only the work efficiency is low, but also the existing direct high-pressure washing method will waste a lot water resources, the cleaning effect is poor

Abstract

The invention provides an open-web girder filter press capable of efficiently cleaning a filter plate, which comprises an open-web girder and a filter plate connected to the upper part of the open-web girder in a sliding manner, and is characterized by further comprising a pre-tightening unit, a cleaning assembly and a stripping assembly, the stripping assembly is arranged at the lower part of the pre-tightening unit; the cleaning assembly is arranged at the side part of the stripping assembly; the stripping assembly comprises a stripping mechanism for grabbing a filter cake and a middle cleaning unit for cleaning a water inlet and a water outlet of a filter plate; after the pre-tightening unit pre-tightens a single filter plate, the stripping assembly firstly strips a filter cake on the surface of the filter plate through a stripping mechanism, then water inlet and outlet holes in the middle of the filter plate are subjected to all-directional cleaning through the middle cleaning unit, and then the cleaning assembly moves downwards step by step; and the surface of the filter plate is brushed back and forth by swinging the rotary brush under the action of the spraying mechanism. According to the invention, the filter cake is stripped in a grabbing manner, so that the convex part used for fixing the filter screen on the surface of the filter plate can be prevented from being damaged during stripping, and the service life of the filter plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of filter cake treatment of filter presses, in particular to a fasting beam filter press with efficient and clean filter plates. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure to the liquid to be filtered to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. [0003] Chinese patent CN110624286B discloses a filter press for sewage treatment, including a base, a frame mounted on the base, a filter plate arranged on the frame, a fixed tail plate and a pressing plate, and the frame is provided with There is a push plate for removing filter cake residues on the filter plate, and a drive device for driving the push plate is fixedly connected to the push plate, and the drive device is fixedly connected to the frame, which is used for filter presses for sewage treatment , through the push plate provid...
