Description

Technical Field

[0001] The invention belongs to the technical field of solid-liquid separation filter pressing, and in particular relates to a horizontal filter pressing device for solid-liquid separation of slurry state materials. Background Art

[0002] The filter press operation can achieve solid-liquid separation of materials. The commonly used equipment is the plate and frame filter press. The filter press process of the plate and frame filter press is a combination of material input precipitation and pressure. The existence of precipitation can make the liquid material form a slurry-state material. Under the condition of applying a certain pressure, the liquid in the slurry-state material is further discharged to form a cake-like material. Since pressure is applied while liquid is input, the applied pressure will interfere with the liquid input precipitation process, resulting in an effective amount of material for a single filter press. Precipitation first and then applying pressure will lead to low efficiency of the entire filter press process. Summary of the invention
