[0002] Inclined plate assemblies are widely used in water treatment sedimentation equipment. When traditional inclined plate assemblies use the shallow pool sedimentation principle to settle the sediment in the sewage flowing through them, the sediment discharged from the water flow space of the inclined plate assembly is easily disturbed by the sewage water body below and re-mixed into the sewage water body, resulting in low sedimentation efficiency of the sediment sludge in the sewage. Summary of the invention

[0006] The first sedimentation component includes a first mud slide, a first baffle and a second baffle. The first mud slide is located on the lower side of the inclined plate and is inclined in a direction opposite to the inclination direction of the inclined plate. The first baffle and the second baffle are respectively arranged on the water inlet side and the water outlet side of the first mud slide, and are enclosed with the first mud slide to form an inclined first mud slide channel. The inclined plate completely protrudes outside the first mud slide channel. The first mud slide channel is used to collect and obliquely discharge the sediment precipitated by the sewage in the process of flowing through the multiple water channels. The first baffle and the second baffle are used to block the sewage from entering the first mud slide channel.

[0007] In one embodiment, the first baffle plate and the second baffle plate are connected to the lower side of the inclined plate at a side away from the first mud slide.

[0026] like Figures 1 to 3 As shown, the sedimentation mechanism 100 in one embodiment includes an inclined plate assembly 110 and a first sedimentation assembly 120. The inclined plate assembly 110 includes a plurality of inclined plates 111 arranged side by side and spaced apart. A water passage 112 for sewage to flow through is formed between any two adjacent inclined plates 111. The first sedimentation assembly 120 includes a first mud slide 121, a first baffle 122 and a second baffle 123. The first mud slide 121 is located at the lower side of the inclined plate 111 and is inclined in a direction opposite to the inclination direction of the inclined plate 111. The first baffle plate 122 and the second baffle plate 123 are respectively arranged on the water inlet side and the water outlet side of the first mud slide plate 121, and are enclosed with the first mud slide plate 121 to form an inclined first mud slide channel 124. The inclined plate 111 completely protrudes from the first mud slide channel 124. The first mud slide channel 124 is used to collect and discharge obliquely downward the sediment precipitated by the sewage in the process of flowing through multiple water channels 112. The first baffle plate 122 and the second baffle plate 123 are used to block the sewage from entering the first mud slide channel 124.

[0027] like Figure 3 and Figure 4As shown, the sedimentation mechanism 100 utilizes the shallow pool sedimentation principle of the inclined plate assembly 110. The sediment obtained by sedimentation during the sewage flowing through the multiple water passages 112 of the inclined plate assembly 110 can be quickly settled to the first mud slide channel 124, and then the sediment output from the multiple water passages 112 is collected and discharged obliquely downward through the first mud slide channel 124. In addition, since the first baffle plate 122 and the second baffle plate 123 are respectively provided on the water inlet side and the water outlet side of the first mud slide plate 121, the first baffle plate 122 and the second baffle plate 123 can prevent the sewage from flowing relative to the first mud slide channel. The first mud channel 124 can be connected to the sewage channel 112 to form a stable static water area, which is conducive to the sediments output from the multiple water channels 112 falling into the first mud channel 124 for concentrated and downward discharge, and can effectively prevent the sediments from being washed out of the first mud channel 124 by the incoming sewage; therefore, the above-mentioned sedimentation mechanism 100 can realize the independent flow of sewage and sediments in the water channel 112 and the first mud channel 124 respectively without interfering with each other, thereby effectively realizing the rapid sedimentation of sediments in sewage and ensuring the clarification of the effluent from the sedimentation mechanism 100.

[0028] In one embodiment, the inclination angle of the inclined plate 111 is 45 to 70 degrees, that is, the angle between the inclined plate 111 and the horizontal plane is 45 to 70 degrees. In one embodiment, any two adjacent inclined plates 111 are arranged in parallel. Further, the spacing between any two adjacent inclined plates 111 is 3 cm to 30 cm, that is, the vertical distance between any two adjacent inclined plates 111 is 3 cm to 30 cm. It should be pointed out that the smaller the spacing between two adjacent inclined plates 111, the faster the sediment in the sewage settles in the water passage 112 formed between the two adjacent inclined plates 111. Further, in this embodiment, the spacing between any two adjacent inclined plates 111 is equal. It can be understood that in other embodiments, the spacing between any two adjacent inclined plates 111 may also be equal or the spacing between some of the adjacent two inclined plates 111 may be equal.

[0029] In one embodiment, the first mud slide 121, the first baffle 122 and the second baffle 123 are enclosed to form a U-shaped structure. Further, the first mud slide 121 is not parallel to the inclined plate 111, that is, the first mud slide 121 is arranged at a certain angle to the inclined plate 111. In one embodiment, the angle formed between the first mud slide 121 and the inclined plate 111 is 30 degrees to 90 degrees. When the angle formed between the first mud slide 121 and the inclined plate 111 is 90 degrees, the first mud slide 121 is arranged perpendicular to the inclined plate 111.

[0030] like Figure 1 and Figure 2As shown, further, the first baffle plate 122 and the second baffle plate 123 are arranged along the normal direction parallel to the first mud slide plate 121, and the first baffle plate 122 and the second baffle plate 123 are respectively fixedly connected to the two long sides of the first mud slide plate 121. In one embodiment, the first baffle plate 122 and the second baffle plate 123 are connected to the lower side of the inclined plate 111 on one side away from the first mud slide plate 121.

[0031] In one embodiment, the inclined plate assembly 110 and the first sedimentation assembly 120 together constitute the first sedimentation unit 130, and the first sedimentation unit 130 includes multiple groups, and the multiple groups of first sedimentation units 130 are arranged in sequence along the extension direction of the inclined plate 111, and the outer side of the first mud slide plate 121 of each group of first sedimentation units 130 is connected to the upper side of the inclined plate 111 of the adjacent first sedimentation unit 130. It can be understood that in other embodiments, according to different use environments of the sedimentation mechanism 100, the multiple groups of first sedimentation units 130 can also have other arrangements, which are not limited here.

The second mud slide 141 is located on the lower side of the first mud slide 121, and is arranged obliquely in a direction opposite to the inclination direction of the first mud slide 121. The second baffle 123 is arranged on the water inlet side and the water outlet side of the second mud slide 141, and is enclosed with the second mud slide 141 to form an obliquely arranged second mud slide channel 144. The second mud slide channel 144 is connected to multiple first mud slide channels 124. The second mud slide channel 144 is used to collect and discharge the sediment output by multiple first mud slide channels 124 obliquely downward. The third baffle 142 and the fourth baffle 143 are used to block the entry of sewage relative to the second mud slide channel 144.

[0033] Specifically, since the third baffle 142 and the fourth baffle 143 are respectively provided on the water inlet side and the water outlet side of the second mud slide 141, the third baffle 142 and the fourth baffle 143 can block the sewage from entering the second mud slide channel 144, so that the second mud slide channel 144 can form a stable still water area, which is conducive to the sediment output by the multiple first mud slide channels 124 falling into the second mud slide channel 144 for concentrated and downward discharge, and can effectively prevent the sediment from being washed out of the second mud slide channel 144 by the incoming sewage, so that the sedimentation mechanism 100 can more effectively realize the rapid sedimentation of the sediment in the sewage and ensure the clarity of the outlet water.

[0034] like Figure 2As shown, in one embodiment, the second mudslide 141 is arranged parallel to the inclined plate 111, that is, the inclination angle of the second mudslide 141 is the same as the inclination angle of the inclined plate 111. Specifically, in one embodiment, the inclination angle of the second mudslide 141 is 45 degrees to 70 degrees, that is, the angle between the second mudslide 141 and the horizontal plane is 45 degrees to 70 degrees. It can be understood that in other embodiments, the second mudslide 141 and the inclined plate 111 can be arranged at a preset angle.

[0035] In one embodiment, the first mud slide plate 121 completely protrudes outside the second mud slide channel 144. Further, the third baffle plate 142 and the fourth baffle plate 143 are connected to the lower sides of the first baffle plate 122 and the second baffle plate 123 and the lowermost inclined plate 111 in the inclined plate assembly 110, respectively. Further, the lowermost inclined plate 111 in the inclined plate assembly 110 constitutes an isolation boundary between the water passage 112 where the inclined plate 111 is located and the second mud slide channel 144.

[0036] Specifically, the third baffle plate 142 and the fourth baffle plate 143 are arranged obliquely in a direction opposite to the inclination direction of the first baffle plate 122. Further, the third baffle plate 142 and the fourth baffle plate 143 are arranged in a normal direction parallel to the second mud slide 141, and the third baffle plate 142 and the fourth baffle plate 143 are fixedly connected to the two long sides of the second mud slide 141 respectively.

[0037] like Figure 1 As shown, in one embodiment, multiple groups of first sedimentation units 130 and second sedimentation assemblies 140 together constitute a second sedimentation unit 150, and the second sedimentation unit 150 includes multiple groups, and the multiple groups of second sedimentation units 150 are arranged in sequence along the horizontal direction, and the outer side of the second mud slide 141 of each group of second sedimentation units 150 is connected to the upper side of the first mud slide 121 of the adjacent second sedimentation unit 150.

The third mud slide channel 164 is connected to multiple first mud slide channels 124. The third mud slide channel 164 is used to collect and vertically discharge sediments output by multiple first mud slide channels 124 downwardly. The third baffle 142 and the fourth baffle 143 are used to block sewage from entering the third mud slide channel 164.

[0039] Specifically, since the fifth baffle 162 and the sixth baffle 163 are respectively provided on the water inlet side and the water outlet side of the third mud slide 161, the fifth baffle 162 and the sixth baffle 163 can block the sewage from entering the third mud slide channel 164, so that the third mud slide channel 164 can form a stable still water area, which is conducive to the sediment output by the multiple first mud slide channels 124 falling into the third mud slide channel 164 for concentrated vertical downward discharge, and can effectively prevent the sediment from being washed out of the third mud slide channel 164 by the incoming sewage, so that the sedimentation mechanism 100 can more effectively realize the rapid sedimentation of the sediment in the sewage and ensure the clarity of the outlet water.

[0040] In one embodiment, the fifth baffle plate 162 and the sixth baffle plate 163 are arranged along a normal direction parallel to the third mud slide plate 161.
