Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater denitrification and phosphorus removal dosing device. Background Technology

[0002] In municipal sewage treatment plants, industrial park wastewater treatment stations, and other scenarios, nitrogen and phosphorus removal are key process steps to control eutrophication of water bodies and ensure that effluent meets standards. The core of these processes relies on chemical dosing methods (such as adding solid agents like polyaluminum chloride, ferrous sulfate, and high-efficiency denitrifying agents) to remove total nitrogen (TN) and total phosphorus (TP).

[0003] However, traditional wastewater denitrification and phosphorus removal dosing devices still have certain drawbacks. For example, traditional dosing devices often directly add solid reagents to the dissolution tank without targeted crushing treatment. Commonly used solid reagents for denitrification and phosphorus removal (such as polyaluminum chloride granules and ferrous sulfate crystals) are mostly in block or large particle form, which are difficult to dissolve quickly if directly added to wastewater, thus slowing down the wastewater treatment process. Secondly, traditional dosing devices often adopt a continuous feeding mode. Although this mode can continuously add reagents, it is easy to cause insufficient mixing between the reagents and wastewater, affecting the pollutant removal effect. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater denitrification and phosphorus removal dosing device that can pulverize the drugs, thereby accelerating the dissolution rate, reducing the reaction time, and allowing the pulverized drugs to be added to the wastewater intermittently, thus ensuring that the drugs react fully with the wastewater and improving the wastewater treatment effect.

[0005] To achieve the above objectives, a wastewater denitrification and phosphorus removal dosing device is provided, comprising: The hopper has a motor fixedly connected to its front surface, a rotating shaft fixedly connected to the output end of the motor, a pressure roller fixedly connected to the outer surface of the rotating shaft, an arc-shaped pressure plate fixedly connected to the inner surface of the hopper, a through hole provided on the outer surface of the arc-shaped pressure plate, and a first conical tooth fixedly connected to the outer surface of the rotating shaft.

[0021] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] Working Principle: During operation, the device is installed above the sewage tank using the fixing buckle 21, mounting holes 22, and bolts. Then, the sewage treatment chemicals are poured into the hopper 1. Simultaneously, the motor 2 is started, driving the rotating shaft 3 to rotate. The chemicals falling into the hopper 1 slide between the pressure roller 4 and the arc-shaped pressure plate 5, where they are crushed by the pressure roller 4. The crushed chemicals then fall through the through hole 6 to the bottom of the hopper 1, and are discharged through the discharge hole 19 via the inclined surface on the inclined block 20, thus completing the dosing operation. The crushed chemicals dissolve more quickly in the sewage. In water, thus reducing reaction time, and the rotation of the rotating shaft 3 can synchronously drive the transmission shaft 9 to rotate under the meshing action of the first conical tooth 7 and the second conical tooth 10. The rotation of the transmission shaft 9 will drive the baffle 15 to move back and forth along the slide rod 17 under the hinge action of the disc 11, the fixed column 12, the long strip plate 13 and the connecting column 14, so that the discharge hole 19 is intermittently exposed. At this time, the drug crushed by the pressure roller 4 will also intermittently fall into the sewage through the discharge hole 19, thereby ensuring that the drug and sewage react fully and improving the sewage treatment effect.
