Description

Technical Field

[0001] The utility model relates to the technical field of sewage filter pressing, in particular to a filter pressing device for preventing filter plate deviation. Background Art

[0002] In industrial production, the filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid can be dialyzed out. It is a mechanical device that is commonly used for solid-liquid separation. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. The filter plate has stable performance, convenient operation, safety and labor saving; the metal pressing cylinder is processed by seamless steel pipe and the plastic steel filter plate is precision cast. It is resistant to high temperature and high pressure and durable. However, during the filtration process, the filter plate is prone to offset, causing liquid leakage.

[0003] The general filter press device for preventing the filter plate from deflecting is provided with a plurality of filter plates between the pressure stop plate and the pressing plate, and the sewage is discharged through the drainage hole and the filter net to discharge the debris, and then the filtered water is sent into the filter pipe through the water delivery hole to complete the filtration. However, this structure is prone to deflection during the process of pressing the filter plate, which affects the effect of the filter pressing and causes the leakage of sewage. The Chinese patent discloses a filter plate anti-deflection detection device for a plate-frame filter press with the application number "CN202223147632.X", which includes a trigger plate arranged on the filter plate of the plate-frame filter press, an alarm device for alarming, and a trigger device arranged between the trigger plate and the alarm device. Through the alarm device, the alarm signal is released, and through the trigger plate, the movement is achieved with the deflection of the filter plate. Through the trigger device, the offset of the filter plate is corrected by the measurement reference line, and the offset limit position of the filter plate is measured online, which solves the technical problem that the offset limit position of the filter plate is observed by the operator, thereby preventing the filter plate from deflecting and improving the working reliability of the plate-frame filter press. However, this structure is complex and needs to be adjusted during the filtration process, resulting in poor overall effect. Utility Model Content
