Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a filter press for solid-liquid separation. Background Technology

[0002] A filter press for solid-liquid separation is a mechanical device that achieves solid-liquid separation by applying pressure. It mainly uses filter media such as filter cloth to trap solid particles and discharge liquid.

[0003] The utility model with announcement number CN222266247U discloses a filter press for solid-liquid separation, including a separation chamber, an inner cover fixedly connected inside the separation chamber, a motor provided on the side wall of the separation chamber, an outer rod fixedly connected to one end of the motor near the separation chamber, an inner rod slidably connected inside the outer rod, one end of the inner rod penetrating the side wall of the inner cover and extending into the inner cover, a pressure plate fixedly connected to one end of the inner rod extending into the inner cover, the pressure plate slidably connected inside the inner cover, and a discharge assembly provided inside the inner cover, the discharge assembly including a discharge plate slidably connected inside the inner cover;

[0004] The above technical solution, through the setting of the discharge component, achieves the following: during solid-liquid separation, the pressure plate slides towards the feed pipe under the drive of the motor. At this time, the first deflector will first contact the drive gear and push the drive gear away. At this time, the drive gear and the control gear are not meshed. As the control rack moves, the pressure plate completes the compression of the material. At this time, the second deflector will also contact the drive gear and push the drive gear towards the pressure plate. However, after the filter press separates the solid and liquid by compressing the material, the solid particles are not easy to discharge quickly, which affects the next filtration and liquid separation. In addition, the solid-liquid separation structure is not easy to remove, replace and clean. Utility Model Content
