Description

Technical Field

[0001] The utility model relates to a spiral conveying mechanism of a filter press, belonging to the technical field of filter presses. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to exert a certain pressure on the material to allow the liquid to penetrate. It belongs to the category of solid-liquid separation equipment. It is widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics and environmental protection industries, mainly used to achieve the solid-liquid separation process.

[0003] A Chinese patent publication (publication number: CN 210456281 U) discloses a screw conveyor for a filter press, comprising a cylinder, a screw conveying rod, a drive motor, a coupling, a rotating shaft, a support, an upper hopper, and a lower hopper. The screw conveying rod is arranged inside the cylinder, one end of the screw conveying rod passes through the cylinder and is connected to one end of the rotating shaft through the coupling, and the other end of the rotating shaft is rotatably connected to the support. The rotating shaft is sleeved with a first bevel gear, and the output end of the drive motor is connected to a second bevel gear, and the first bevel gear is meshed with the second bevel gear. The upper hopper is arranged on the upper part of the cylinder, and the lower hopper is arranged on the lower part of the cylinder. The utility model has the advantages of small cross-sectional size of the whole machine, good sealing performance, stable and reliable operation, multi-point loading and unloading, safe operation, and simple maintenance.

[0004] One of the core components of the filter press is the screw conveying system, which is responsible for conveying solid materials to the filter cloth and achieving solid-liquid separation through compression. The design and optimization of the screw conveying system is crucial to the overall performance of the filter press. The above patent drives the screw conveying rod to rotate through a coupling via a drive motor. The upper hopper is used for feeding and the lower hopper is used for discharging. The first bearing and the second bearing can reduce friction, but there are still certain defects. During the conveying process, lumped or adhered materials will cause blockage, causing the material to accumulate in the upper hopper, making the feeding extremely unsmooth and affecting the subsequent work process.

[0005] Therefore, a screw conveying mechanism of a filter press is proposed. Utility Model Content
