Description

Technical Field

[0001] The utility model specifically relates to the technical field of medicament dosing, in particular to a dosing device for a dephosphorization medicament. Background Art

[0002] Phosphorus removal agents are a type of chemical used to remove excess phosphorus in water or soil. Phosphorus removal agents are available in liquid and solid forms, so different equipment is required to add the agents. However, when adding traditional solid agents, it is impossible to effectively ensure the ratio between the agent and the sewage. Therefore, when removing phosphorus from sewage, it may cause insufficient flocculation and the sewage cannot meet the discharge standards.

[0003] At present, when adding traditional chemicals, they are usually loaded with weight to ensure the ratio with sewage. Although flocculation can be achieved, as the sewage increases, it is necessary to frequently add chemicals to the flocculation box, which reduces work efficiency and may cause errors when loading.

[0004] After searching, Chinese patent publication number CN202021740802.3 discloses a phosphorus removal agent dosing device; comprising a fixed frame, on which a dropper device is installed, the dropper device comprises a square ring tube, a plurality of water flow holes are evenly spaced around the outer circumference of the ring tube, a dropper is horizontally fixed on the water flow hole, the input end of the dropper is fixedly connected to the water flow hole, the ring tube is provided with a liquid inlet hole, and a liquid inlet pipe is horizontally fixed on the liquid inlet hole;

[0005] When adding the dephosphorizing agent, the structure in the above patent adds it to the inside of the ring tube through the liquid inlet pipe, and drips through the drip tube. Although the addition of the agent can be achieved, the flow rate of the agent is fast at the beginning. As the amount of the agent decreases, the flow rate of the agent will slow down. This will cause uneven addition of the agent, and thus, when performing dephosphorization, the formation of the flocculation structure cannot be effectively guaranteed, and the phosphorus element in the sewage cannot be completely removed. Therefore, the structure in the above patent still has certain technical defects;

[0006] In view of the above situation, we provide a dosing device for phosphorus removal agents. In this device, the tank body is connected to the first liquid dosing structure, the second liquid dosing structure and the third liquid dosing structure through a conveying pipe, so that the liquid agent can be added. A quantitative agent dosing component is also installed on the top of the tank body to add fixed agents. When the fixed agent is added, the agent enters the cylinder body through the dosing barrel, and the driving motor drives the active gear to realize the toothed belt to drive the driven gear to rotate. When the driven gear rotates, the first stirring rod and the second stirring rod installed on the two cylinders rotate, which effectively realizes the stirring or crushing of the agent, and then the stepping motor drives the rotating shaft to realize the rotation of the spiral conveying rod. The rotation of the spiral conveying rod effectively adds the agent to the inside of the tank body in a quantitative manner, ensuring the formation of a flocculation structure during sewage treatment. Utility Model Content
