[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a multi-stage filtration sedimentation tank system, including a shell 1, which is embedded in the foundation. An inlet valve 3 is provided on the left outer wall of the shell 1, and a drain valve 4 is provided on the right outer wall of the shell 1. By providing the inlet valve 3 and the drain valve 4, sewage can enter the interior of the shell 1 through the inlet valve 3, and after passing through two sets of partition plates 2 to separate the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank, the settled water can be discharged out through the drain valve 4 for recycling. The inner side wall of the shell 1 is fixedly connected to the left and right sets of partition plates 2, and a T-shaped bracket 5 is fixedly connected to the top left side of the shell 1. A stirring mechanism 6 is provided on the surface of the T-shaped bracket 5.

[0033] Reference Figure 2 and Figure 3 The stirring mechanism 6 includes a bracket 61, which is fixedly connected to the top of the outer wall of the T-shaped bracket 5. A dual-shaft motor 62 is fixedly connected to the end of the bracket 61 away from the T-shaped bracket 5. The dual-shaft motor 62 is provided with upper and lower output shafts, and the dual-shaft motor 62 is existing technology. A gear a63 is fixedly connected to the lower output shaft of the dual-shaft motor 62. The gear a63 is rotatably connected to the left side of the top of the T-shaped bracket 5. A gear ring 64 meshes with the left outer wall of the gear a63. A rack is provided on the inner ring of the gear ring 64, and it matches the tooth pitch of the gear ring 64. A connecting rod 65 is fixedly connected to the bottom of the inner side wall of the gear ring 64. The inner arc surface of the gear ring 64 is divided into upper and lower layers, and the upper layer is provided with a rack. A set of connecting rods 65 is fixed to the lower layer and is fixed to the rotating sleeve 66 through the connecting rods 65. When the gear ring 64 meshes with the gear a63, the gear ring 64 will drive the rotating sleeve 66 to rotate synchronously through the connecting rods 65. The rotating sleeve 66 is fixedly connected to the end of the connecting rod 65 away from the gear ring 64. The rotating sleeve 66 passes through and is rotatably connected to the inner wall of the T-shaped bracket 5. The inner wall of the T-shaped bracket 5 has a cavity that fits the rotating sleeve 66. The upper end of the side wall of the rotating sleeve 66 is fixedly connected to the upper dispersing rod 67. When the rotating sleeve 66 rotates, it will drive the upper dispersing rod 67 to rotate synchronously. Thus, when the coagulant is added to the storage tank 73, it can be stirred to accelerate the dissolution of the coagulant.

[0034] Reference Figure 3 Gear b68 meshes with the right outer wall of gear a63. Gear b68 is rotatably connected to the top of the outer wall of the rotating sleeve 66 and the top of the outer wall of the T-shaped bracket 5. A rotating rod 69 is fixedly connected to the rotation center shaft of gear b68. The rotating rod 69 passes through and is rotatably connected to the inner wall of the rotating sleeve 66. When gear b68 meshes with the right side of gear a63, the rotation of gear a63 will cause the gear ring 64 to rotate in the opposite direction. At the same time, the rotation of gear a63 will drive gear b68 to rotate in the opposite direction. A lower dispersing rod 610 is fixedly connected to the outer wall of the bottom end of the rotating rod 69. The lower dispersing rod 610 has two sets of rods, which intersect with the upper dispersing rod 67, so that the upper dispersing rod 67 and the lower dispersing rod 610 can rotate in opposite directions when rotating, thereby quickly dissolving the coagulant. A quantitative feeding component 7 is provided at the top of the dual-shaft motor 62.

[0035] Reference Figure 2 and Figure 4 The quantitative feeding component 7 includes a turntable 71. The rotation center axis of the turntable 71 is fixedly connected to the output shaft at the upper end of the dual-axis motor 62. When the dual-axis motor 62 drives the gear a63 to rotate, it will also drive the turntable 71 to rotate synchronously. A hinge rod 72 is hinged to the surface of the turntable 71 away from the center point.

[0036] Reference Figure 4The storage box 73 is hinged to the end of the hinge rod 72 away from the turntable 71. The inner side of the storage box 73 is provided with an inclined surface. When the turntable 71 rotates, it will rotate around the hinge point on its surface through the hinge rod 72, thereby driving the storage box 73 to swing back and forth. At the same time, the bottom of the storage box 73 initially overlaps with the top of the shell 1. When the storage box 73 is pulled to the outermost position by the hinge rod 72, the filter plate 74 at its bottom will discharge part of the coagulant stored inside the turntable 71 from the filter hole. This is repeated to achieve quantitative feeding and prevent excessive feeding at one time, which would not be able to mix the coagulant sufficiently. The filter plate 74 is fixedly connected to the bottom of the inner wall of the storage box 73, and the guide block 75 is fixedly connected to the bottom of the outer wall of the storage box 73. The surface of the shell 1 is provided with a guide groove. The guide block 75 passes through and slides on the inner wall of the guide groove of the shell 1. By setting the guide block 75, the movement position of the storage box 73 can be guided, so that it can only move back and forth.

[0037] Working principle: Wastewater enters the interior of the shell 1 through the inlet valve 3 and passes through the first sedimentation tank, the second sedimentation tank and the third sedimentation tank separated by the partition plate 2 in sequence. During the sedimentation process, solid particles and other impurities in the wastewater gradually settle to the bottom of the tank under the action of gravity. After multiple stages of sedimentation, the relatively clear water is discharged from the drain valve 4, realizing the initial purification of wastewater for subsequent recycling.

[0038] When coagulant needs to be added to the first sedimentation tank, the dual-shaft motor 62 operates, and its upper output shaft drives the turntable 71 to rotate. The rotation of the turntable 71 drives the storage tank 73 to swing back and forth around the hinge point and center through the hinge rod 72. The bottom of the storage tank 73 initially overlaps with the top of the shell 1. When it is pulled to the outermost position by the hinge rod 72, the coagulant in the storage tank 73 is partially discharged through the filter holes of the filter plate 74 under the action of gravity. Due to the reciprocating swing of the storage tank 73, the coagulant is discharged at a time, avoiding the problem of insufficient mixing of the coagulant caused by excessive discharge at one time. At the same time, the guide block 75 slides in the guide groove of the shell 1 to guide the movement of the storage tank 73 and ensure its stability and accuracy.

[0039] Simultaneously, the dual-shaft motor 62 starts, and its lower output shaft drives gear a63 to rotate. Gear a63 meshes with gear ring 64, and the inner ring rack of gear ring 64 meshes with gear a63, causing gear ring 64 to rotate. Gear ring 64 drives rotating sleeve 66 to rotate synchronously through connecting rod 65. When rotating sleeve 66 rotates, it drives upper dispersing rod 67 to rotate, stirring the added coagulant and accelerating its dissolution. When gear a63 rotates, it drives gear ring 64 to rotate in the opposite direction on one hand, and gear b68 to rotate in the opposite direction on the other. The rotation of gear b68 drives lower dispersing rod 610 to rotate through rotating rod 69. Since lower dispersing rod 610 and upper dispersing rod 67 cross and rotate in opposite directions, they can more effectively stir the coagulant during rotation, quickly achieving the dissolution and mixing of the coagulant and improving the sedimentation effect.

[0040] 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.
