Description

Technical Field

[0001] The utility model relates to the technical field of grille decontamination, in particular to a rotary mechanical grille. Background Art

[0002] The rotary screen machine is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment, tap water industry, and power plant water inlet. It can also be used as a pre-screening equipment in wastewater treatment processes in textile, food processing, papermaking, leather and other industries.

[0003] When the rotary mechanical screen is used for pollution removal, some pollutants in the sewage will be lifted up by the rotary screen. When the rake teeth run to the upper part of the equipment, the pollutants will fall into the slag collecting bucket under the action of their own weight. Since the pollutants contain a lot of water, the load-bearing capacity of the equipment is increased, and the slag collecting bucket needs to be replaced every once in a while, which greatly reduces the working efficiency of the rotary mechanical screen. For this reason, we proposed a rotary mechanical screen. Utility Model Content
