Description

Anti-blocking dosing structure Technical Field The utility model relates to the technical field of sewage treatment, in particular to an anti-blocking dosing structure. Background The chemical agent is added into the sewage to make phosphorus react with metal ions in the dephosphorization agent to generate insoluble phosphate precipitate, so that phosphorus is removed from the sewage. Common chemicals are aluminum salts (e.g., aluminum sulfate, polyaluminum chloride, etc.), iron salts (e.g., ferric trichloride, ferrous sulfate, etc.), and calcium salts (e.g., lime, etc.). When in actual use, the dephosphorization medicament is placed in the medicament tank, the lower part is connected with the medicament outlet pipeline, the valve is arranged on the medicament outlet pipeline, the dephosphorization medicament in the medicament tank is downwards output based on the medicament outlet pipeline under the action of gravity, however, some dephosphorization medicaments are sticky and can accumulate in the medicament outlet pipeline, the flow is reduced, even the dephosphorization medicament is blocked when serious, and the dephosphorization effect is influenced. Disclosure of utility model The utility model aims to provide an anti-blocking dosing structure, which solves the problem that a drug outlet pipeline provided in the background technology is easy to be blocked by a dephosphorization medicament. In order to achieve the purpose, the utility model provides the following technical scheme that the anti-blocking dosing structure comprises: a medicament storage tank, a medicament outlet pipe and a medicament supply pipe; The upper end of the medicine outlet pipe is connected with the lower surface of the medicine storage tank, a three-way joint is arranged on a pipeline of the medicine outlet pipe, the medicine supply pipe is communicated with the medicine outlet pipe through the three-way joint, the upper end of the medicine outlet pipe is a flushing port, and the lower end of the medicine outlet pipe is a medicine outlet; The pipeline of the medicine supply pipe is provided with a valve and a flow sensor, the valve is positioned at the downstream of the flow sensor, the flow sensor is externally connected with a PLC controller, and an alarm is integrated on the PLC controller.
