Pressure filter

Abstract

The invention discloses a pressure filter which includes: a machine frame, a thrust plate, a pressing plate, a hydraulic cylinder, and a plurality of pressure filter plates that are arranged between the pressing plate and the thrust plate. Filter clothes are arranged on the two ends of each pressure filter plate. A rotating ring is rotatably connected to each pressure filter plate. A driving member is arranged on the rotating ring. Each rotating ring is provided with two material pushing rods. An accommodating groove is arranged on the end surface of each pressure filter plate. A spring is disposed in the accommodating groove and is connected to the filter clothes. When the pressure filter is in use, the driving member drives the rotating ring to rotate the material pushing rods, and whena material pushing ring rotates to a position, the material pushing ring jacks up the filter clothes at the positions, so that the filter clothes are separated from the pressure filter plates. When the material pushing rods rotates from the positions, the spring at the position drives the filter clothes to move towards one side of the accommodating groove; at the same time, foreign matters attached to the filter clothes are removed from the filter clothes under effect of inertia, so that the filter pores in the filter clothes are not liable to be blocked by the foreign matters. The structure can ensure the pressure filter effect of the pressure filter to certain degree.

Description

technical field [0001] The invention relates to the technical field of liquid extraction equipment, in particular to a filter press. Background technique [0002] A filter press is a kind of mechanical equipment that uses a special filter medium to apply a certain pressure to the object to make the liquid dialysis out. It is a commonly used solid-liquid separation equipment. [0003] At present, the Chinese patent with the notification number CN105771348A discloses a high-efficiency filter press, which includes a frame, a thrust plate fixedly connected to the frame, a compression plate slidably connected to the frame, and a A hydraulic cylinder for pushing the pressure plate to move, the thrust plate is provided with a material inlet hole, and a filter unit is arranged between the pressure plate and the thrust plate, and the filter unit includes several filter press units. Frame, the center of the filter press frame is provided with a feed hole, and liquid outlet holes are ...

AI Technical Summary

Problems solved by technology

[0005] However, during the use of the filter press, as the number of solid particles in the filter chamber gradually increases, more and more filter holes on the filter cloth will be blocked by solid particles, making the separation effect of the filter cloth on materials gradually weakened. , so that the liquid inside the filter chamber needs a longer time to fully pass through the filter cloth and be discharged from the liquid outlet hole, which reduces the filter press effect of the filter press to a certain extent.
