Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for adding chemicals. Background Technology

[0002] In the field of wastewater treatment, chemical dosing systems are one of the key pieces of equipment for achieving water purification. With the acceleration of industrialization and increasingly stringent environmental requirements, the scale and complexity of wastewater treatment are constantly increasing, placing higher demands on the performance, automation, and ease of maintenance of chemical dosing systems. Traditional wastewater treatment processes can no longer meet modern society's expectations for wastewater treatment efficiency and quality; therefore, an improved chemical dosing system for wastewater treatment is of significant practical importance. Many existing wastewater treatment systems rely primarily on manual operation in the dosing process. Workers pour pre-prepared chemicals into the wastewater tank through specific dosing ports according to a pre-set dosing plan and proportion. Manual dosing mainly relies on the gravity of the chemicals themselves and the water flow within the wastewater tank to disperse and mix the chemicals. The diffusion rate and uniformity of the chemicals in the wastewater are affected by various factors such as water flow velocity, direction, and the physicochemical properties of the chemicals themselves, making precise control difficult.

[0003] However, a significant problem with existing technology is that the filter screen cannot be disassembled for cleaning. In wastewater treatment, the filter screen is used to intercept large particles and undissolved chemical residues, preventing them from entering subsequent treatment stages. However, with prolonged use, the filter screen pores gradually become clogged, leading to decreased filtration efficiency and affecting the normal operation of the entire system. Because the filter screen is designed for fixed installation, disassembly is cumbersome and complex, requiring time and effort from professional personnel, which not only increases maintenance costs but can also cause interruptions to the wastewater treatment process.

A roller 20 is rotatably connected to one side of the outer wall of the rotating shaft 21. The roller 20 is in contact with one side of the outer wall of the moving block 15. When the moving block 15 moves, the roller 20 rotates around the rotating shaft 21 as the center along the outer wall of the moving block 15, thereby driving the fixing strip 19 to rotate around the rotating shaft 18 as the center, realizing the opening and closing of the fixing strip 19. This design facilitates the fixing and disassembly of the filter screen, and is beneficial for cleaning and replacing the filter screen. A filter screen 8 is provided on one side of the outer wall of the fixing strip 19, and a filter plate 7 is slidably connected to one side of the outer wall of the filter screen 8. The filter plate 7 has a groove inside that fits with the fixing block 11. A positioning strip 10 is slidably connected inside the filter plate 7 to prevent displacement or loosening during the filtration process. The positioning strip 10 is fixedly connected to the inner wall of the filter tank 2. The combined design of the filter screen 8 and the filter plate 7 can effectively intercept impurities and suspended solids in the sewage, improving the filtration effect.

A rotating plate 29 is fixedly connected to one end of the connecting rod 30. A fan 31 is fixedly connected to one side of the outer wall of the rotating rod 28. A blocking ball 34 is rotatably connected to the inner wall of the medicine barrel 24. The medicine channel can be opened or closed by rotating the blocking ball 34. A connecting rod 32 is fixedly connected to one side of the outer wall of the medicine barrel 24. A rotating block 33 is fixedly connected to one end of the connecting rod 32. The connecting rod 32 and the blocking ball 34 can be rotated by rotating the rotating block 33. Working principle: When using this device to treat sewage, firstly, the groove inside the filter plate 7 is pressed down by the positioning strip 10, so that the fixing block 11 is inserted into the groove inside the filter plate 7. Then, the filter screen 8 is placed in the inner wall of the filter plate 7. Subsequently, the rocker arm 12 is rotated to drive the moving block 15 to move with the cooperation of the positioning block 14 and the positioning strip 16, so that the roller 20 rotates around the rotating shaft 21 as the center along the outer wall of the moving block 15, thereby causing the fixing strip 19 to rotate around the rotating shaft 18 with the cooperation of the bracket 17, so that one side of the outer wall of the fixing strip 19 is in contact with one side of the outer wall of the filter screen 8. At this time, the filter screen 8 is fixed. The valve 6 is opened, and the sewage in the sewage tank 1 flows into the filter tank 2 through the pipe 5. The filter plate 7 and the filter screen 8 perform the first filtration of the sewage. Then, it flows into the dosing tank 3 through the pipe 5 for the second filtration. Finally, it flows into the water storage tank 4 through the pipe 5.

[0026] When using this device to treat wastewater, first pour the chemicals into the chemical tank 24. Then, turn on 36 to rotate the rotating rod 28, causing the connecting rod 30 and the fan 31 to rotate. The rotation of the connecting rod 30 causes the rotating plate 29 to rotate along the inner wall of the chemical tank 24, thoroughly stirring the chemicals. After stirring, rotate the rotating block 33 to rotate the connecting rod 32, causing the blocking ball 34 to rotate. This allows the chemicals to flow through the holes in the blocking ball 34 into the transport pipe 23, and then into the dosing tank 3 for further treatment of the wastewater.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
