Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a filter cake quick-disassembly plate and frame filter press. Background Art

[0002] A plate and frame filter press is an intermittently operated solid-liquid separation device widely used in the chemical, petroleum, metallurgy, and environmental protection industries. It primarily consists of filter plates and a filter frame. By pressing the plates and frame together, pressure is applied to compress and filter the material, thereby achieving solid-liquid separation. Plate and frame filter presses are typically used to process low-viscosity, low-residue liquids, such as solutions and suspensions in the pharmaceutical, chemical, and food industries. They feature a large filtration area and high flow rate, making them suitable for acidic and alkaline solutions with a wide range of pH values. Furthermore, they offer high filtration force, a high filter cake solids content, clear filtrate, and a high solids recovery rate.

[0003] The application number is 201521109931.1, which is a plate and frame filter press capable of quickly removing filter cakes. In this case, a plurality of filter plate and frame assemblies, a compression plate and a thrust plate are connected in series by configuring an articulated telescopic assembly, so that when removing the filter cake, the compression plate can be contracted to synchronously loosen the plurality of filter plate and frame assemblies arranged in pairs, thereby causing the plurality of formed filter cakes to automatically and synchronously fall off. In the above case, when filtering the material, the two compression plates squeeze each other, and a gap is left between the compression plates, which will result in low quality of material filtration. In addition, in the existing filter cake quick-removal plate and frame filter press, the current method of removing the filter cake is still to manually loosen the filter plates and filter plates arranged in pairs one by one, so that the filter cake can be automatically peeled off, resulting in the inability to remove the filter cake efficiently and quickly.
