Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a multi-media sewage treatment system. Background Art

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily life of ordinary people. Multi-media filters are often used to filter sewage during sewage treatment. Multi-media filters use one or more filter media to pass water with high turbidity through a certain thickness of granular or non-granular materials under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment turbidity removal, softened water, and pre-treatment of pure water.

[0003] At present, when setting up a multi-media filter, a variety of filter media are layered and laid inside the filter box. This media laying method only relies on the mutual overlap between different media layers to connect the media layers. When encountering turbulent water flow, it is easy to disperse the different media layers, causing the different media to mix with each other, thereby destroying the filtering effect of the original media layer.

[0033] like Figure 2 , Figure 4 and Figure 6 As shown, the drainage assembly includes a movable rod 34, an adjusting cavity 33 is opened on the inner bottom surface of the storage cavity 23, the movable rod 34 is slidably connected between the inner walls of the adjusting cavity 33, the top of the movable rod 34 extends to the inside of the storage cavity 23, and is directly opposite to one side of the wedge-shaped opening 20, a pressure rod 37 is fixed to the bottom of the movable rod 34, the bottom of the pressure rod 37 slides through the inside of the U-shaped cavity 26, a first spring 38 is fixed to the bottom of the movable rod 34, and the bottom of the first spring 38 is fixed to the inner bottom surface of the adjusting cavity 33, and the movable rod 34 is fixed to the inner bottom surface of the adjusting cavity 33. A transition chamber 35 is provided inside the rod 34 near the top edge, and a plurality of side openings 36 are provided on the inner wall of the transition chamber 35 at equal intervals along the circumferential direction and penetrate to the outside of the movable rod 34. A bridge interface 39 is provided on the inner wall of one side of the regulating chamber 33, and one side of the bridge interface 39 is communicated with the water outlet 22. Trapezoidal grooves 24 are provided on the inner bottom surface of the storage chamber 23 near the edges on both sides, and drainage channels 25 are provided on the inner bottom surfaces of the two trapezoidal grooves 24, and one end of the two drainage channels 25 are communicated with the inside of the regulating chamber 33.

[0034] The effect achieved is that when the multi-media filter box 16 is installed inside the storage chamber 23, in the process of pushing the multi-media filter box 16 into the storage chamber 23, the movable rod 34 is pressed downward through the wedge-shaped opening 20, so that the side opening 36 on the movable rod 34 is connected with the bridge interface 39 and the two drainage channels 25. At this time, the first spring 38 is in a compressed state. When the water inside the buffer chamber 21 flows into the storage chamber 23, the water flows out from the bottom after being filtered by the multi-media filter box 16. In the storage chamber 23, the water first converges in the trapezoidal groove 24, and then enters the transition chamber 35 through the drainage channel 25 and the side opening 36, and then flows from the transition chamber 35 through the side opening 36 into the bridge interface 39, and finally is discharged from the outlet 22.

[0035] like Figure 5 and Figure 7 As shown, the positioning assembly includes two dial plates 27, and the two dial plates 27 are rotatably connected between the front and rear inner walls of the U-shaped cavity 26. One end of the two dial plates 27 extends to the middle part of the U-shaped cavity 26 and fits with the bottom of the pressure rod 37. The other ends of the two dial plates 27 extend to the edge of the U-shaped cavity 26. Adjustment rods 28 are slidably provided at the edges of both sides of the U-shaped cavity 26. The tops of the two adjustment rods 28 are inclined, and the bottoms of the two adjustment rods 28 fit with the other ends of the dial plates 27. The inner sides of the filter box 9 are The walls are each provided with a sliding cavity 42, a positioning rod 43 is provided inside the two sliding cavities 42, an annular plate 45 is provided on the outer surface of the two positioning rods 43, the two annular plates 45 are correspondingly slidably connected between the inner walls of the sliding cavity 42, a second spring 44 is fixed on one side of the two annular plates 45, one end of the two second springs 44 is correspondingly fixed on one inner wall of the sliding cavity 42, one end of the two positioning rods 43 slides through the inside of the side of the U-shaped cavity 26, and the other end of the two positioning rods 43 slides through the inside of the storage cavity 23.

[0036] The effect achieved is that when the movable rod 34 moves downward, it will drive the pressure rod 37 to slide downward, so that the pressure rod 37 presses one end of the dial plate 27 downward, and then the other end of the dial plate 27 is tilted upward to drive the adjustment rod 28 to slide upward. During the upward sliding process of the adjustment rod 28, since the top of the adjustment rod 28 is inclined, the positioning rod 43 slides toward the inside of the storage chamber 23 under the pressure of the inclined surface, thereby positioning the multi-media filter box 16 to prevent the multi-media filter box 16 from shaking due to the impact of water flow during filtration.

[0037] like Figure 5 and Figure 7As shown, the partitioned water supply assembly includes a plurality of reciprocating plates 30, a plurality of reciprocating grooves 31 are equidistantly provided at the bottom of the buffer chamber 21 inside the filter box 9, a transmission chamber 40 is provided at one side of the plurality of reciprocating grooves 31 inside the filter box 9, the plurality of reciprocating grooves 31 are interconnected with the transmission chamber 40, the plurality of reciprocating plates 30 are correspondingly slidably connected between the inner walls of the reciprocating grooves 31, a plurality of through holes 29 are equidistantly provided on the top and bottom surfaces of the plurality of reciprocating grooves 31, the through holes 29 located at the top of the reciprocating grooves 31 penetrate into the interior of the buffer chamber 21, and the through holes 29 located at the bottom of the reciprocating grooves 31 penetrate into the interior of the buffer chamber 21. The through hole 29 penetrates into the interior of the storage cavity 23, and multiple through holes 32 are equidistantly provided on the tops of the multiple reciprocating plates 30, and the multiple through holes 32 are offset and opposite to the through holes 29. A connecting plate 41 is provided inside the transmission cavity 40, and one end of the multiple reciprocating plates 30 is correspondingly fixed on the outer surface of one side of the connecting plate 41. A guide opening 46 that penetrates into the interior of the transmission cavity 40 is provided on the inner top surface of the sliding cavity 42, and a push plate 47 is fixed on the top of the annular plate 45. The push plate 47 is slidably connected between the inner walls of the guide opening 46, and the top of the push plate 47 is fixed to the rear side of the connecting plate 41.

[0038] The effect achieved is that when the positioning rod 43 slides toward the inside of the storage chamber 23, it will drive the push plate 47 to push the connecting plate 41 toward one side of the transmission chamber 40, and when pushing, it will drive multiple reciprocating plates 30 to slide inside the reciprocating groove 31. Since the through holes 32 and the through holes 29 on the reciprocating plates 30 are offset and relative to each other in the initial state, multiple through holes 29 are not conductive in the initial state. After the reciprocating plate 30 slides, the through holes 32 and the through holes 29 can be made opposite to each other. At this time, the water flow inside the buffer chamber 21 can flow into the inside of the storage chamber 23 through the through holes 29, and then evenly flow into the multi-media filter box 16 for filtration.

[0039] Working principle: first, different media are loaded into the storage box 17, and then the storage box 17 is installed inside the storage port 18. At this time, the layered assembly of different media can be installed. Then, when the multi-media filter box 16 is installed inside the storage chamber 23, in the process of pushing the multi-media filter box 16 into the storage chamber 23, the movable rod 34 is pressed downward through the wedge-shaped port 20, so that the side port 36 on the movable rod 34 is connected with the bridge interface 39 and the two drainage channels 25. At this time, the first spring 38 is in a compressed state. When the water in the buffer chamber 21 flows into the storage chamber 23, the water flows out from the bottom after being filtered by the multi-media filter box 16. In the storage chamber 23, the water first converges in the trapezoidal groove 24, and then enters the transition chamber 35 through the drainage channel 25 and the side port 36, and then flows from the transition chamber 35 through the side port 36 into the bridge interface 39, and finally is discharged from the outlet 22. When the filter element 34 moves downward, the pressure rod 37 will be driven to slide downward, so that the pressure rod 37 presses one end of the dial plate 27 downward, thereby causing the other end of the dial plate 27 to tilt upward and drive the adjustment rod 28 to slide upward. During the upward sliding process of the adjustment rod 28, since the top of the adjustment rod 28 is inclined, the positioning rod 43 slides toward the inside of the storage chamber 23 under the pressure of the inclined surface, thereby positioning the multi-media filter box 16 to prevent the multi-media filter box 16 from shaking due to the impact of water flow during filtration. When the positioning rod 43 slides toward the inside of the storage chamber 23, it will drive the push plate 47 to push the connecting plate 41 toward one side of the transmission chamber 40. When pushing, it will drive multiple reciprocating plates 30 to slide inside the reciprocating groove 31. After the reciprocating plate 30 slides, the through hole 32 can be opposite to the through hole 29. At this time, the water flow inside the buffer chamber 21 can flow into the inside of the storage chamber 23 through the through hole 29, and then evenly flow into the multi-media filter box 16 for filtration.
