Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment grid machines, and in particular relates to a grid machine for sewage treatment. Background Art

[0002] Wastewater treatment: the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Screen machines are needed in the sewage treatment process.

[0003] The existing public patent number is CN220495790U, and the public name is a screen machine for sewage treatment, which belongs to the field of sewage treatment equipment. The screen machine for sewage treatment consists of a primary filter tank connected to a secondary filter tank through a connecting pipe. The primary filter tank is provided with an inner partition net, and the inner partition net is staggered inside the primary filter tank. The primary filter tank effectively filters the sewage and can filter most of the solid matter. The sewage filtered by the primary filter tank enters the secondary filter tank through the connecting pipe for re-filtration treatment. The screen machine is arranged in the secondary filter tank to treat the sewage. The treated solid matter enters the treatment tank along the inclined partition net and is crushed and then recovered from the recovery port.

[0004] However, when the above-mentioned screen machine filters garbage in sewage, when the screen machine transfers the debris to the upper end, the debris mixed in the sewage is easily accumulated on the rake teeth and is difficult to be separated from the collection bucket. The treatment effect of the filtered garbage is poor, and the garbage cannot be effectively treated, resulting in garbage accumulation and pollution. Utility Model Content
