Abstract
Description
Technical Field
[0001] The utility model relates to the field of filter press control, in particular to an automatic locking device for an oil cylinder of a plate and frame filter press. Background Art
[0002] The oil cylinder of the plate and frame filter press is the core component of the hydraulic clamping mechanism, which can press the filter plate and the filter frame tightly together to form a closed filter chamber, thereby realizing the solid-liquid separation process. During the operation of the filter press, excessive radial load on the oil cylinder will cause pressure fluctuations in the system, which may cause the oil cylinder to retreat and cause danger. Utility Model Content
[0003] The utility model is based on the above technical problems and proposes an automatic locking device for the oil cylinder of a plate and frame filter press.
[0004] The camshaft is an oil cylinder of the oil pump, and the camshaft is an oil pump that is mounted on the oil pump side of the oil pump body. The camshaft is an oil pump that is mounted on the oil pump side of the oil pump body. The camshaft is an oil pump that is mounted on the oil pump side of the oil pump body.
[0005] Preferably, an insertion rod is provided on the inner side of one of the lifting and reverse thrust stop seats, and a slot corresponding to the insertion rod is provided on the inner side of the other lifting and reverse thrust stop seat.
[0006] Preferably, the driving device is an opening and closing oil cylinder, and the piston rod of the opening and closing oil cylinder is connected and fixed to the outer side of the lifting and reverse thrust stop seat.
[0007] Beneficial effect: The automatic locking device is arranged on the front side of the cylinder seat, and uses the driving device to push the lifting and reverse thrust stop seat to lock the cylinder rod of the cylinder. After the lifting and reverse thrust stop seat is locked and buckled, it can prevent the radial load of the cylinder from being too large. BRIEF DESCRIPTION OF THE DRAWINGS
