Description

[0002] As the core equipment of solid-liquid separation, the efficiency and stability of the feeding link of the belt filter directly affect the filtering effect and productivity. Most of the existing belt filter feed hoppers have simple structure and single function, and the screen part is often in a relatively static state, and only relies on the gravity of the material itself to complete the preliminary screening through the screen. However, in actual production, the material characteristics are complex and diverse, containing fine particles, fibrous impurities and sticky components, which are prone to accumulate and adhere on the surface of the screen. With the extension of the running time of the equipment, these accumulated materials will gradually block the screen pores, resulting in a significant reduction of the effective filtering area of the screen, a significant increase of the difficulty of the material passing through the screen, and a slow feeding speed and a significant reduction of the feeding efficiency.

[0003] In addition, the existing belt filter feed hopper lacks a material dispersion structure, and the material in the feed hopper is prone to block the discharge port, so that the material cannot uniformly enter the subsequent filtering link, resulting in a difference in the feeding amount of each part of the belt filter, which not only affects the consistency of the filtering effect and reduces the filtering quality, but also further reduces the production efficiency.
