Description

Technical Field

[0001] The utility model relates to the technical field of filter plates, in particular to a filter plate of a filter press that is easy to clean. Background Art

[0002] In modern industrial production, as an important separation device, the filter press is widely used in many fields such as chemical industry, pharmaceutical industry, food processing, mining and wastewater treatment. The filter press applies pressure to the liquid containing suspended solids to make the liquid pass through a filter medium such as a filter screen for filtration and separation, thereby achieving the purpose of liquid-solid separation. In the wastewater generated during the printing process, such as the wastewater generated from cleaning printing presses, ink pools, coating equipment, etc., the treatment of the wastewater usually includes pretreatment (such as oil separation, sedimentation), biological treatment (such as the activated sludge method), chemical treatment (such as flocculation, oxidation) and final filtration. The filter press can play a key role in this process. At the same time, the filter plate is the core component of the filter press, and its design and function directly affect the filtration efficiency, effect and operation convenience.

[0003] In the prior art, the existing filter plate cleaning is to use clean water to rinse in the filter press body and then brush it once with a brush. The cleaning itself is not thorough enough. After the filter plate is used for a long time, the filter screen often needs to be deeply cleaned or replaced due to blockage or wear. The existing filter plate and the filter screen are of an integral structure and cannot be separated. To deeply clean, only the filter plate can be completely removed from the filter press, which greatly reduces the cleaning and maintenance efficiency, thereby increasing the downtime and reducing the production efficiency.
