Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater treatment technology, specifically a chemical wastewater reagent dispersion dosing device. Background Technology

[0002] Chemical production processes generate large amounts of wastewater with complex compositions and high pollutant concentrations. If this wastewater is discharged directly without effective treatment, it will cause serious environmental pollution, endanger ecological balance and human health. Therefore, chemical wastewater treatment is one of the key links in the sustainable development of the chemical industry. In the chemical wastewater treatment process, the addition of chemicals is a crucial step. By adding specific chemicals to the wastewater, functions such as removing pollutants, purifying water quality, and adjusting pH value can be achieved. Common chemicals include flocculants, coagulants, acid-base regulators, and disinfectants.

[0003] However, existing chemical dosing devices often cannot guarantee that the chemicals are fully and evenly dispersed in the wastewater. This is because the dosing pipes and nozzles are usually fixed, resulting in a small dosing area. It is difficult to quickly mix the chemicals with the wastewater in different areas, which may lead to excessively high chemical concentrations in some areas, causing over-reaction and increasing treatment costs. Meanwhile, the chemical concentrations in other areas are insufficient, which cannot effectively remove pollutants and affect the overall wastewater treatment effect. Utility Model Content

[0033] Example 1:

[0034] Please see Figures 1-7 As shown, this utility model provides a chemical wastewater reagent dispersion dosing device, comprising:

[0035] Wastewater treatment tank 1, with bases 6 fixedly installed at both ends of the top of the wastewater treatment tank 1, and toothed plates 38 fixedly installed at the top of the inner cavity of the base 6.

[0036] The medicine tank 2 is located in front of the sewage treatment tank 1. A PLC controller 3 is fixedly installed on the front surface of the medicine tank 2. A delivery pump 13 is fixedly installed on the lower right side of the medicine tank 2 through a pipe. A delivery pipe 4 is fixedly installed at the output end of the delivery pump 13. A dosing nozzle 15 is fixedly installed at the upper end of the delivery pipe 4. A nozzle 19 is provided at the bottom of the dosing nozzle 15.

[0037] The fixed frame 10 is installed above the sewage treatment tank 1. The lower ends of both sides of the fixed frame 10 are movably connected to the drive shaft 37 through bearings. A circular gear 28 is fixedly installed on the side of the two drive shafts 37 that are far apart from each other. The circular gear 28 meshes with the toothed plate 38.

[0038] A dual-axis motor 29 is fixedly installed on the top center of the outer surface of the fixed frame 10. Two rotating shafts 31 are fixedly installed on both sides of the output end of the dual-axis motor 29. A first synchronous pulley 32 is fixedly installed at the ends of the two rotating shafts 31 that are far apart from each other. A synchronous belt 33 is connected between the middle end of the first synchronous pulley 32 and the middle end of the second synchronous pulley 36.

[0039] Two rotating rods 34 are movably connected to the top of the fixed frame 10 via bearings. A second bevel gear 35 is fixedly installed on the top of the rotating rod 34, and the second bevel gear 35 meshes with the first bevel gear 30. An L-shaped rod 23 is fixedly connected to the bottom of the rotating rod 34. A connecting plate 24 is movably connected to the two L-shaped rods 23 at their far ends via bearings. An adjusting frame 27 is movably connected to the two connecting plates 24 at their far ends via bearings. The top of the injection nozzle 15 is fixedly installed at the bottom of the adjusting frame 27.

[0040] In this technical solution, when it is necessary to add chemicals to the sewage inside the sewage treatment tank 1, the PLC controller 3 starts the delivery pump 13 to extract the chemicals from the chemical tank 2 and deliver them to the dosing nozzle 15 through the delivery pipe 4. At the same time, the chemicals are sprayed into the sewage below through the nozzle 19 to achieve the effect of adding chemicals to the sewage. Simultaneously, the PLC controller 3 starts the dual-axis motor 29 to drive the rotating shaft 31, the first bevel gear 30, and the first synchronous pulley 32 to rotate. The rotation of the first synchronous pulley 32 drives the second synchronous pulley 36, the drive shaft 37, and the circular gear 28 to rotate via the synchronous belt 33. The rotation of the circular gear 28... Simultaneously, it can move along the surface of the toothed plate 38, and drive the fixed frame 10, adjusting frame 27, dosing nozzle 15 and nozzle 19 to move, thus adding the agent to the sewage in different areas, effectively improving the uniformity of the agent dosing operation. At the same time, the rotation of the first bevel gear 30 can drive the second bevel gear 35, rotating rod 34 and L-shaped rod 23 to rotate. When the L-shaped rod 23 rotates, it can drive the adjusting frame 27, dosing nozzle 15 and nozzle 19 to reciprocate in the horizontal direction through the connecting plate 24, which can further add the agent to the sewage in different areas, greatly improving the uniformity of the agent dosing operation and ensuring the quality of sewage treatment operation.

Under the pressure of the agent delivery, the dispersing blade 22 and the turntable 21 can be driven to rotate, and the agent is evenly dispersed in all directions under the action of the rotation of the dispersing blade 22 and the turntable 21, thereby improving the uniformity of agent addition.
