During the use of the filter press, a second water pump above the water tank is started, and the clean water in the water tank is used to rinse the materials in the filter press to rinse away the filtered impurities. At the same time, a filter plate is installed above the water tank to separate impurities from the clean water used for rinsing, which is convenient for the recycling of clean water and brings convenience to people's use. However, when the filter plate in the device is filtering, impurities gather in the center of the filter plate, which can easily lead to clogging of the filter plate and the inability of water to pass through. In addition, the filter plate in the water tank is in a static state for a long time, so the filtration efficiency is low and the practicability of the device is low.
