Description

Technical Field

[0001] The invention relates to the technical field of material filter pressing and dehydration, in particular to a plate and frame filter press. Background Art

[0002] Filter press is a kind of mechanical equipment which uses filter medium to exert pressure on the object to make the liquid seep out. It is mainly used for solid-liquid separation in the field of material pressure filtration and dehydration technology. Filter press is widely used and is widely applicable to sludge dehydration in wastewater treatment processes in urban sewage treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical industry, slaughtering, food, brewing and environmental protection projects. It can also be used for solid-liquid separation in industrial production. It is an ideal equipment for environmental governance and resource recovery. It can also be applied to solid-liquid separation or liquid leaching processes in industrial production, and is also widely used in domestic environmental protection engineering projects. However, the existing filter press has the problem that when the mud blocks are discharged after filtration, the mud blocks stick to the filter cloth and do not fall off, and manual cleaning is often required, which is labor-intensive and causes waste of manpower and material resources. After the mud blocks are removed, the filter cloth needs to be cleaned, and water washing is often used, which causes waste of water resources. At the same time, the mud blocks need to be removed first during water washing, and then a water retaining device is required to block the mud blocks below for cleaning. The work is cumbersome, the process is complicated, which affects efficiency, and also causes waste of water. At the same time, there is a risk of water falling onto the filtered mud blocks below.
