Description

Technical Field

[0001] The utility model relates to the field of filter plates, in particular to a filter plate used for a disc filter. Background Art

[0002] Disc filter is a commonly used solid-liquid separation equipment, which can be used for liquid filtration and sludge dehydration in food, chemical, pharmaceutical and other industries. The working principle of disc filter is to filter out solid particles after the liquid passes through the filter medium, and discharge the liquid through the pipe. The advantage of disc filter is that it can continuously and efficiently process a large amount of liquid, and can automatically clean the filter medium, reducing the cost and labor intensity of manual cleaning.

[0003] The disc filter mainly filters and separates impurities or dirt in the water through filter plates to treat the water. The filter plates in the disc filter are fan-shaped. When the filter plates are used, the fan-shaped filter plates are usually installed at corresponding positions on the disc filter at intervals along the circumferential direction, so that the fan-shaped filter plates are assembled into a circular ring shape for use in the disc filter.

[0004] However, the existing filter plate cannot be easily replaced during use. After long-term use, a certain amount of dirt is likely to accumulate in the filter plate. After the dirt accumulates in the filter plate, it is likely to cause wear on the filter plate. The inconvenience in replacing the filter plate affects the work efficiency of replacing the filter plate, and it is not convenient to replace filter plates with different sector angles according to the size of the disc filter.

[0005] Therefore, we propose a filter plate for a disc filter. Utility Model Content
