Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a feeding device for a filter press. Background Art

[0002] A filter press is a device used for solid-liquid separation and is widely used in chemical, mining, metallurgy, food processing and other fields. Its main function is to separate solid particles from liquid media by physical methods, thereby obtaining dry solid or solid-liquid products. As an efficient solid-liquid separation equipment, the filter press plays an important role in industrial production. It can not only improve product quality, but also reduce the discharge of waste and wastewater, which meets the requirements of modern industry for resource and environmental protection.

[0003] Before using a traditional filter press, sewage containing sediment is usually discharged into the filter device to filter out large particles or impurities in the sewage. The filtered sewage is passed through the filter press to separate the solid and liquid. Due to the fast water flow during drainage, the impurities in the sewage will quickly accumulate on the surface of the filter plate, causing some impurities to be blocked in the leakage holes of the filter plate, slowing down the initial water inlet speed, affecting the subsequent work process, and thus affecting the efficiency of sewage treatment.
