Sewage treatment device capable of automatically adjusting chemical adding amount according to sewage flow

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage treatment device capable of automatically adjusting chemical adding amount according to sewage flow. The devicecomprises a box body, the bottom of the box body is fixedly connected with a water filtering cylinder, the interior of the water filtering cylinder is fixedly connected with a filtering plate, the bottom of the water filtering cylinder is fixedly connected with a reset spring, a movable plate is fixedly connected to the top of the reset spring, a conical rod is fixedly connected to the left sideof the top of the movable plate, a fixed block and a buffer tank are fixedly connected to the left side of the water filtering cylinder, a movable valve is inserted into the fixed block, and a chemical pipe is fixedly connected to the left side of the bottom of the buffer tank. The filtering plate is gradually blocked by solid impurities, impact force borne by the movable plate is reduced, the movable plate slowly rises under the action of the reset spring, then a conical rod is driven to rise, and the movable valve moves leftwards when the conical rod rises, so that the amount of chemicals flowing out of the chemical pipe is reduced, and the effect of automatically adjusting the chemical adding amount according to the flow of the filtered sewage is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device that automatically adjusts the dosage of chemicals according to the flow of sewage. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. . [0003] With the improvement of people's awareness of environmental protection, sewage treatment has attracted more and more attention. Since sewage contains a large amount of solid impurities, it is necessary to filter sewage before chemical treatment of sewage to remove solid impurities in sewage. The current The filter plate of the sewage filtration device is easy to be blocked during filtration, an...
