Sewage filtering residue scraping device

Abstract

The invention discloses a waste water filtering slag scraping device, which comprises a liquid storage bin, a filter plate is arranged on the liquid storage bin, a liquid inlet bin is arranged on the filter plate; one side of the filter plate is arranged on the liquid storage bin through a rotating shaft, and the rotating shaft Connected with a motor, the side wall of the liquid inlet bin is provided with a slag outlet at the rotating shaft; the liquid inlet bin is provided with a liquid inlet pipe; the bottom of the liquid storage bin is provided with an agitator, and the side of the liquid storage bin It is equipped with a liquid outlet pipe and a dosing pipe, and a liquid outlet pump is arranged on the liquid outlet pipe; it also includes a plurality of slag scraping units arranged side by side above the filter plate, one end of the plurality of slag scraping units is connected by a connecting rod, and the connecting rod There is a push rod on the push rod, a long rod is hinged on the push rod, a short rod is hinged on the long rod, and a motor is connected to the short rod; The slag scraping plate, the two ends of the slag scraping rod are fixed on the filter plate through the guide seat. The invention can carry out pre-filtering, guarantee the reaction effect, and can guarantee the filtering effect of the filter plate at the same time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage filtering and scraping device. Background technique [0002] With the country's economic development and modernization process, various types of environmental pollution are increasingly affecting our lives, especially water pollution is the number one threat. In order to control the pollution of sewage to the environment, sewage is now concentrated in sewage treatment plants for comprehensive treatment to meet the discharge standards stipulated by the state. [0003] In the process of sewage treatment, it is necessary to add chemical solution for reaction treatment. However, at present, the chemical treatment is carried out directly in the sewage tank, and there are the following problems: the sewage has not been pre-treated, and since the sewage contains a large amount of particulate matter, direct chemical injection will affect the reaction effect.
