This application discloses a deviation measuring mechanism and a material conveying device. The material conveying device forms a thick section and at least one thin section. The deviation measuring mechanism includes a mounting frame, a triggering member, and a detection member. The detection member sequentially forms a substandard detection area, a standard detection area, and an over-standard detection area along the thickness direction of the material conveying device. When the triggering member comes into contact with the thin section, it is pushed by the thin section so that at least part of it is placed in the substandard detection area and outside the standard detection area. The triggering member can come into contact with the thick section and be pushed by the thick section so that at least part of it moves from the substandard detection area to the standard detection area and is outside the over-standard detection area. The triggering member can be further pushed by the thick section it comes into contact with so that at least part of it moves from the standard detection area to the over-standard detection area. When the detection member detects that at least part of the triggering member is placed in the substandard detection area and outside the standard detection area or at least part of it is placed in the over-standard detection area, it generates a corresponding deviation correction signal.

This utility model discloses a continuous automatic fiber ball filter device, belonging to the field of wastewater treatment technology. It includes a filter body, a fiber ball filter assembly disposed within the filter body, and a connecting pipeline assembly connected to the filter body. During filtration, the water to be filtered effectively removes suspended solids, colloids, organic matter, and other impurities through the interception, adsorption, and bridging effects of the fiber ball filter media. Furthermore, the gap between the fiber ball filter media can be flexibly adjusted using a hydraulically driven extrusion screen. On one hand, the compressed state traps smaller particle sizes of impurities, while the loose state facilitates backwashing, adapting to different water quality requirements. On the other hand, the backwash water flow causes the fiber ball filter media to expand and loosen. The position of the extrusion screen can be adjusted via the hydraulic cylinder to prevent excessive expansion and damage to the fiber ball filter media, while also ensuring good backwashing effect and avoiding impurity residue.
