Description

Technical Field

[0001] The invention relates to the technical field of filter press devices, in particular to intelligent operation equipment for a filter press with a monitoring device. Background Art

[0002] A solid-liquid separation device is a device that separates solids and liquids in a solid-liquid mixture. Among them, a filter press is a commonly used solid-liquid separation device. A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object to allow liquid to seep out. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection industries. In the environmental protection industry, filter presses are widely used in sewage treatment.

[0003] Among many filter press equipment, chamber filter press is widely used. The working principle of chamber filter press is that filter plates are arranged to form a filter chamber (the two sides of the filter plates are recessed, and every two filter plates are combined into a chamber). There are pitting and bosses on the surface of the filter plate to support the filter cloth. There are through holes in the center and corners of the filter plate. After assembly, a complete channel is formed to allow the suspension, washing water and filtrate to enter. There are handles on both sides of the filter plate to support the crossbeam, and the filter plate is pressed by a clamping device. The filter cloth between the filter plates acts as a seal.

[0004] Under the pressure of the feed pump, the material liquid to be filtered is sent into each filter chamber, and the solid and liquid are separated by the filter medium (the appropriate filter cloth is selected according to different industries). Filter residue is formed on the filter cloth until it fills the filter chamber to form a filter cake. The filtrate passes through the filter cloth and flows along the filter plate groove to the outlet channel below and is discharged in a centralized manner. After the filtration is completed, clean washing water can be introduced to wash the filter residue. After washing, compressed air is sometimes introduced to remove the remaining washing liquid. After the filtration is completed, open the filter press to remove the filter cake (the filter cake is stored between two adjacent filter plates), clean the filter cloth, and re-press the plate filter to start the next working cycle.

[0005] In the actual working process of the filter press, the filtration efficiency is easily affected by many factors such as the feed pressure, the particle size composition of the feed slurry and the feed slurry concentration. However, it is difficult for the existing filter press to measure the above parameters and adjust the feed slurry parameters. Summary of the invention
