[0001] The utility model relates to the technical field of sewage treatment, in particular to a sand settling device for sewage treatment. Background Art
[0002] Wastewater treatment refers to the process of purifying wastewater so that it can meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.
[0003] At present, traditional sand settling devices can already perform basic sand settling and filtering operations. However, in their actual use, the amount of sand accumulated at the bottom of the traditional sand settling device cannot be effectively controlled, resulting in some particles in the sand floating in the sand settling tank. When the water pump is working, the suction pipe will directly suck away the floating sand. When a large amount of sand enters the suction pipe, it is very easy to cause the pipe or water pump to be blocked. Therefore, there is an urgent need for a sand settling device for sewage treatment.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-4A sand settling device for sewage treatment comprises a sand settling tank 1, a sludge pipe 3 is arranged on one side of the sand settling tank 1, electric reels 4 are arranged on both sides of the adjacent edges of the sludge pipe 3 through a mounting frame 2, a winding chain 14 is wound around the electric reel 4, the other end of the winding chain 14 is connected to a plate frame 6, and one end of the plate frame 6 is rotatably mounted on the inner wall of the sand settling tank 1;
[0022] Furthermore, an arc-shaped filter screen 61 is provided at the bottom of the plate frame 6 , and a pumping head 7 is slidably mounted in the middle of the plate frame 6 through a limiting protrusion 12 , and a water pipe 71 is fixedly mounted inside the pumping head 7 .
[0023] Furthermore, a slope 101 is provided at the bottom of the sedimentation tank 1 , and the slope 101 is inclined toward the opposite direction of the sludge pipe 3 , and a sand discharge port 9 is provided on one side of the slope 101 .
[0024] Furthermore, rotating seats 10 are provided on both sides of the inner wall of the sedimentation tank 1, and a plate frame 6 is rotatably mounted on the rotating seat 10. A plurality of cross bars are provided in the middle of the plate frame 6, and a limiting protrusion 12 is provided on the cross bars.
[0025] Furthermore, a hook ring 13 is installed at the front end of the plate frame 6 , a winding chain 14 is connected to the hook ring 13 , and the other end of the winding chain 14 is connected to the electric reel 4 .
[0026] Furthermore, a water pump 5 is fixedly mounted on one side of the upper portion of the mounting frame 2 , and one end of the water pump 5 is connected to the water pump head 7 via a water pipe 71 .
[0027] Furthermore, the pumping head 7 is in the shape of a hollow cylinder with a sealed bottom and an open top, and a gap is left between the water pipe 71 and the pumping head 7, wherein a sliding groove 11 is provided on the outer side of the pumping head 7, and a limiting protrusion 12 is installed in the sliding groove 11 for limiting sliding.
[0028] The bottom of the silt collecting tank 1 is provided with a slope 101, which guides the sand and gravel, and then the silt after sedimentation accumulates at the bottom. At this time, the electric reel 4 is driven to release the rope, and the plate frame 6 is flipped downward under the action of the winding chain 14. The bottom of the plate frame 6 is provided with an arc filter 61. The arc filter 61 can press down the floating particles floating in the muddy water during the flipping process to avoid the situation where the particles are sucked into the water pipe during the subsequent pumping process. At the same time, when the plate frames 6 on both sides are all lowered, the water pump 5 starts working. Since the pumping head 7 is hollow cylindrical, its bottom is sealed and the top is open, and there is a gap between the water pipe 71 and the pumping head 7, the muddy water is introduced into the water pipe 71 from the upper part of the pumping head 7, which can effectively prevent the sand and gravel at the bottom from entering the water pipe. At the same time, when the muddy water is extracted, the sand is discharged through the sand discharge port 9 set on the slope 101.
[0029] At the same time, during actual use, the sliding groove 11 arranged in the pumping head 7 slides on the limiting protrusion 12 in the middle of the plate frame 6 during the flipping process of the plate frame 6, which effectively ensures the buffer margin before and after the flipping. During the flipping process, the pumping head 7 rotates through the limiting protrusion 12 to avoid bending and damage of the water pipe.
[0030] It is worth noting that the removal effect of floating particles can be improved by increasing the size of the plate frame 6, thereby improving the purification efficiency.
[0031] In the utility model, a slope 101 is arranged in the sedimentation tank 1 to avoid the accumulation of sand and gravel. At the same time, plate racks controlled by electric drums are arranged on both sides of the sedimentation tank 1. During the pumping process, the plate racks are flipped so that the particles floating in the water are pressed underneath. Moreover, the sand and gravel at the bottom can be effectively prevented from being sucked into the water pipe through the inverted water-suction pumping head, which effectively avoids the blockage of the pipe, thereby improving the filtering efficiency of the device.
[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
