Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a pretreatment device for domestic wastewater purification. Background Technology

[0002] Domestic sewage refers to wastewater generated in daily life, mainly from households, government offices, businesses, and urban public facilities. Its sources encompass a variety of daily activities such as cooking, bathing, washing, and flushing toilets. It has a complex composition, including organic matter, suspended solids, microorganisms, and nitrogen and phosphorus nutrients, and may also contain small amounts of chemicals from detergents. If this type of sewage is discharged directly without treatment, it will pollute the water and soil ecosystems, such as causing eutrophication, promoting algae and aquatic plant growth, disrupting the aquatic ecological balance, and potentially spreading pathogens and parasites, endangering human health and the survival of plants and animals.

[0003] Wastewater treatment is a crucial link in ensuring the sustainable use of water resources and maintaining the health of the ecological environment. Through a series of physical, chemical, and biological treatment technologies, various pollutants in domestic wastewater are removed or transformed to meet discharge and reuse standards. The treatment process typically includes three stages: pretreatment, biological treatment, and advanced treatment. However, pretreatment is often required to enhance the purification effect. With the advancement of technology, pretreatment facilities mainly use physical and preliminary physicochemical methods to remove easily separable coarse impurities, suspended solids, and some pollutants from wastewater, creating favorable conditions for subsequent core processes such as biochemical treatment. However, these pretreatment facilities cannot agitate the wastewater, resulting in uneven mixing of the internal solution, incomplete sedimentation, and poor treatment effect. Utility Model Content

[0039] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The sedimentation mechanism 4 includes a sedimentation cylinder 401, the top of which is fixedly connected to the bottom of the conical connecting cylinder 1. The inner wall of the sedimentation cylinder 401 is provided with multiple annular grooves 402. The support mechanism 5 includes a support ring 501, which can provide support.

[0040] Specifically, the sedimentation mechanism 4 includes a sedimentation cylinder 401, the top of which is tightly connected to the bottom of the conical connecting cylinder 1 by a fixed connection.

[0042] Specifically, the connecting mechanism 6 includes a connecting pipe 601, the bottom of which is connected to the top of the conical connecting cylinder 1, ensuring a seamless connection between the two. A valve 602 is rotatably connected to the inner wall of the connecting pipe 601. This valve 602 can control the fluid flow inside the connecting pipe 601, thereby achieving precise control of the entire system. In addition, a sedimentation pipe 10 is fixedly connected to the bottom of the sedimentation cylinder 401 near the middle.

The main function of this water outlet pipe 9 is to discharge the liquid inside the sedimentation cylinder 401, ensuring the smooth operation of the entire system, effectively separating and discharging sediment, while maintaining the smooth flow of liquid.

[0043] Working principle: First, water is added through the filter bucket 301. After filtration, the water enters the connecting pipe 601. Then, the valve 602 is opened, and the water enters the conical connecting cylinder 1 through the connecting pipe 601. At this time, the motor 201 is started, which drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the cylindrical sleeve 203 and the connecting plate 204 to rotate. At the same time, the connecting plate 204 drives the annular fixed ring 205 to rotate. The annular fixed ring 205 drives the rotating plate 2061 and the cylindrical blade 2062 to rotate. At this time, the cylindrical blade 2062 will stir the water inside the sedimentation cylinder 401 until it is evenly mixed. Then, the motor 201 is turned off, and the aqueous solution is allowed to settle. The sediment in the aqueous solution will settle inside the sedimentation tube 10. The settled water can then be drawn out through the water outlet pipe 9, thus achieving the function of sedimentation of filtered water.

[0044] First, the water will be filtered through the filter plate 3053 on the filter barrel 301. When the filter plate 3053 is clogged, first turn the rotating handle 302. At this time, the rotating handle 302 will drive the rotating sleeve 304 to rotate until the rotating sleeve 304 is blocked by the first locking post 303. Then, lift the connecting ring 3052 upward. At this time, the second locking post 3051 will leave the filter barrel 301, and then the inside of the connecting ring 3052 can be cleaned. After cleaning, the connecting ring 3052 is put back into the filter barrel 301. At this time, the second locking post 3051 will be locked inside the filter barrel 301. Then, turn the rotating sleeve 304 back to fix the connecting ring 3052 inside, which realizes the function of disassembling and cleaning the filtered filter plate 3053.
