Flocculating agent feeding device for sewage treatment

Abstract

The invention discloses a flocculating agent feeding device for sewage treatment, which belongs to the technical field of sewage treatment. A flocculating agent feeding device for sewage treatment comprises a tank body and an intermittent feeding mechanism, a driving assembly is connected to the top wall of the tank body, the output end of the driving assembly is connected with a first rotating shaft and a second rotating shaft, first transmission assemblies matched with each other are arranged on the outer walls of the first rotating shaft and the second rotating shaft, the output end of thefirst transmission assembly is connected with a second transmission assembly, the outer walls of the output ends of the first transmission assembly, the second transmission assembly and the first rotating shaft are connected with stirring assemblies, the stirring assemblies are matched with one another, one end of the intermittent feeding mechanism is connected to the outer wall of the tank body,and the other end is connected with the second rotating shaft. The device is simple in structure and convenient to use, the mixing reaction effect of a flocculating agent and sewage can be effectivelyimproved, then the flocculating effect of the flocculating agent is effectively improved, and therefore sewage treatment is cleaner and more thorough.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a flocculant feeding device for sewage treatment. 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. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people. [0003] After searching, the invention patent with the publication number CN107265593A discloses an energy-saving and environment-friendly sewage treatment equipment based on the principle of quantitative and uniform feeding. A rotating shaft, the first rotating shaft is arranged vertically, the lower end of the first rotating shaft extends downward through the housing, and the bottom end of...

[0003] After searching, the invention patent with the publication number CN107265593A discloses an energy-saving and environment-friendly sewage treatment equipment based on the principle of quantitative and uniform feeding. A rotating shaft, the first rotating shaft is arranged vertically, the lower end of the first rotating shaft extends downward through the housing, and the bottom end of the first rotating shaft is fixedly connected with the output shaft of the first motor. The present invention has the following beneficial effects: first, The use of the feeding device to achieve precise quantitative addition of flocculants each time reduces the use of an operator, saves human resources, and reduces the cost of sewage treatment; second, the induced draft fan introduces the outside air to the first stage through the intake hose In the second cavity, the second cavity is pressurized, so that the flocculant inside the second cavity can be evenly sprayed from the spray hole, and just mixed with the sewage evenly sprayed from the water spray port. Greatly improved the mixing effect of sewage and flocculant; although the device can improve the mixing effect between sewage and flocculant to a certain extent, it is easy to cause blockage of the water nozzle in the process of mixing sewage and flocculant situation, which in turn affects the mixing effect of sewage and flocculant, so the device still has some shortcomings
