Description

Technical Field

[0001] The utility model relates to the technical field of filter plate pulling of filter presses, and in particular to a filter plate pulling device of a diaphragm filter press. Background Art

[0002] The plate pulling trolley of the high-efficiency diaphragm filter press is mainly used to pull apart the filter plates of the high-efficiency diaphragm filter press, so as to unload the pressed filter cake. During the process of pulling apart the filter plates, the plate pulling trolley needs to walk on the guide rail. The plate pulling trolley is driven by a chain through an electric motor. The plate pulling trolley and the guide rail are in contact with each other using a wear-resistant slider to ensure close contact between the trolley and the rail, while ensuring that the plate pulling trolley moves smoothly on the rail.

[0003] In the daily operation of the existing plate-pulling trolley, the wear-resistant slider of the plate-pulling trolley and the guide rail are particularly prone to jamming, causing the plate-pulling trolley to be damaged and malfunction, causing the high-efficiency diaphragm filter press to shut down. In addition, the wear-resistant slider of the plate-pulling trolley is severely worn, and the wear gap between the wear-resistant block and the track becomes larger, resulting in the inability of the plate-pulling trolley to effectively contact the guide rail, and it is easy to derail and jump teeth when pulling the plate. Therefore, frequent maintenance and replacement are required, which increases material costs and labor intensity, and seriously shortens the continuous operation cycle of the equipment. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a filter plate pulling device for a diaphragm filter press, which uses a guide wheel as a guide mechanism and completes the relative movement between the pulling car and the guide rail through the rotation of the guide wheel, thereby reducing the mutual friction between the pulling car and the guide rail, extending the service life of the equipment, reducing maintenance costs and labor, and avoiding production stoppage caused by maintenance affecting equipment operation.
