Environment-friendly water filtering device

Abstract

The invention relates to a water filtering device, in particular to an environment-friendly water filtering device. The technical problem to be solved is to provide an automatic environment-friendly water filtering device capable of automatically cleaning a filter screen. According to the technical scheme, the environment-friendly water filtering device comprises a mounting cylinder, a feeding port and a discharging port, one side of the mounting cylinder is fixedly connected with the feeding port used for inputting waste water to be treated, and the discharging port is fixedly connected to the mounting cylinder. When a water storage barrel ascends, a fixing plate stops an extrusion rod from moving upwards, the water storage barrel continues to ascend, a liquid outlet pipe is of a thin-end-up structure, and a small ball, clamped in the liquid outlet pipe, at the bottom of the extrusion rod moves downwards, so that a gap is formed between the small ball at the bottom of the extrusion rod and the liquid outlet pipe; therefore, the wastewater is sprayed to the inner wall of the filter screen in the water storage box from the gaps under the action of gravity, the effect of cleaning the filter screen is achieved, and the influence on the wastewater filtering effect caused by blockage of the filter screen is avoided.

Description

technical field [0001] The invention relates to a water filtering device, in particular to a water filtering device for environmental protection. Background technique [0002] Water pollution is becoming more and more serious in modern society, but the treatment of polluted water is really a matter of high cost and low return. Many companies have taken the initiative to stand up and contribute their own strength to sewage treatment, but these polluted water The processing capacity is still far from meeting the current water pollution, which makes it urgent to need a device with lower cost and higher income in the matter of water pollution treatment. [0003] Patent application CN212076708U, published on December 04, 2020, discloses an environmental protection water filtration device, specifically related to the technical field of environmental protection equipment, including a water tank, universal wheels, and a water filtration device. The bottom of the water filtration dev...
