Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency, energy-saving, anti-clogging continuous sand-water separation device. Background Technology

[0002] Sand-containing wastewater refers to wastewater containing a certain amount of sand particles. These sand particles may originate from natural geological conditions, industrial production processes, or urban infrastructure construction and maintenance activities. Sand-water separation is a key step in the treatment of sand-containing wastewater. The main process of sand-water separation is to pump the sand particles along with the wastewater from the sedimentation tank sludge collection hopper to the sand-water separator using a sand pump. The sand particles are then discharged through the top outlet of the guide screw in the sand-water separator, while the wastewater flows back to the grit chamber through the overflow outlet.

[0003] However, in the existing sand-water separator, sand particles are easily stuck in the gap between the guide screw and the liner during use, which can cause equipment blockage and shutdown, affecting the sand-water separation efficiency. At the same time, the sand particles stuck in the gap between the guide screw and the liner can also increase the running resistance of the guide screw, increase the wear of the guide screw, and thus increase the energy consumption of the equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a highly efficient and energy-saving anti-clogging continuous sand-water separation device.

[0005] The technical solution of this utility model is: a high-efficiency and energy-saving anti-clogging sand-water continuous separation device, including a frame, a pre-sinking tank set on the frame, and a separation component set on the frame and connected to the pre-sinking tank;

[0006] The bottom of the pre-settling tank is equipped with a conical sedimentation hopper, and the bottom of the conical sedimentation hopper is equipped with a discharge pipe; the side wall of the pre-settling tank is equipped with an overflow pipe, and the top is equipped with a feed pipe;

[0007] The separation assembly includes a material trough tilted on the frame, a wear-resistant bushing at the bottom of the material trough, a guide screw rotatably engaged inside the material trough, and a drive motor at the end of the material trough with its output end connected to the guide screw; one end of the material trough is connected to the feed pipe, and the bottom surface of the other end is provided with a sand discharge hopper; the end of the material trough connected to the feed pipe is lower than the end of the material trough away from the feed pipe, and the end of the material trough away from the feed pipe is higher than the pre-sinking tank;

[0008] Furthermore, several settling rings are evenly distributed from top to bottom on the inner wall of the conical sedimentation hopper; the settling rings are provided with through holes, and the settling rings have a conical structure;

[0009] Explanation: By setting a conical settling ring, it is possible to prevent sand-containing wastewater from carrying sand particles out of the overflow pipe under the impact of water flow.

[0010] Furthermore, the end of the guide screw away from the drive motor is connected to an incomplete gear via an extension shaft; a rack that meshes with the incomplete gear is slidably engaged at the end of the feed trough, and a return spring that abuts against the inner wall of the feed trough is provided at the end of the rack.

[0011] The wear-resistant bushing is slidably engaged at the bottom of the material trough. The side wall of the wear-resistant bushing is provided with toothed grooves. The end of the material trough is rotatably engaged with a rotating shaft. One end of the rotating shaft is connected to a small gear that meshes with the toothed grooves, and the other end of the rotating shaft is connected to a swing rod that slidably engages with the side wall of the rack.

[0012] Explanation: During the rotation of the guide screw, the incomplete gear is driven to rotate through the extension shaft; at this time, the rack swings back and forth at the end of the feed trough under the action of the incomplete gear; at this time, the swing rod drives the pinion to rotate back and forth through the rotating shaft, and the wear-resistant bushing swings back and forth along the inner wall of the bottom of the feed trough under the meshing action of the tooth groove and the pinion, so as to avoid sand particles getting stuck in the gap between the guide screw and the wear-resistant bushing and causing equipment blockage.

[0013] Furthermore, a rotating rod is rotatably engaged on the inner side of the wear-resistant bushing;

[0014] Note: By setting a rotating bar, the risk of sand particles getting stuck between the guide screw and the wear-resistant bushing is further reduced, thus improving the operational reliability of the equipment.

[0015] The working principle of this utility model is as follows:

[0016] Wastewater containing sand is fed into the pre-sedimentation tank through the feed pipe. The sand particles in the wastewater settle into the conical sedimentation hopper under gravity. The drive motor drives the guide screw to rotate, and the wastewater containing sand rises along the feed trough under the action of the guide screw. Under gravity, the wastewater flows to the bottom of the feed trough through the gap between the guide screw and the wear-resistant bushing, and finally flows out through the overflow pipe. The sand particles are discharged through the sand discharge hopper, realizing the separation of sand and water. During the rotation of the guide screw, the incomplete gear is driven to rotate through the extension shaft. At this time, the rack swings back and forth at the end of the feed trough under the action of the incomplete gear. At this time, the swing rod drives the pinion to rotate back and forth through the rotating shaft. The wear-resistant bushing swings back and forth along the inner wall of the bottom of the feed trough under the meshing action of the tooth groove and the pinion, so as to prevent sand particles from getting stuck in the gap between the guide screw and the wear-resistant bushing.

[0017] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0018] First, the structure of this utility model is reasonably designed. By setting up a pre-sedimentation tank, the sand particles in the sand-containing wastewater are pre-sedimented under the action of gravity, which reduces the difficulty of separating sand-containing wastewater and reduces the operating load of the separation components, thereby reducing the energy consumption of the equipment.

[0019] Secondly, by setting a wear-resistant bushing that can reciprocate inside the feed trough, this utility model can prevent sand particles from getting stuck in the gap between the guide screw and the wear-resistant bushing, thus avoiding equipment blockage and improving the operational stability and reliability of the equipment.

[0020] Third, by setting a rotating rod on the wear-resistant bushing, this utility model helps to reduce the running resistance of the guide screw, reduce the wear of the guide screw, and also helps to reduce the power consumption of the drive motor. Attached Figure Description

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that:

[0033] like Figure 1 , 2 As shown, three settling rings 24 are evenly distributed from top to bottom on the inner wall of the conical sedimentation hopper 20; the settling rings 24 are provided with through holes and have a conical structure.

[0034] By setting a conical settling ring 24, it is possible to prevent sand-containing sewage from carrying sand particles out of the overflow pipe 22 under the impact of water flow.

[0035] Example 3

[0036] The difference between this embodiment and Embodiment 2 is that:

[0037] like Figure 1 , 3 As shown in Figure 4, the end of the guide screw 32 away from the drive motor 33 is connected to an incomplete gear 321 via an extension shaft 320; the end of the material trough 30 is slidably engaged with a rack 34 that meshes with the incomplete gear 321, and the end of the rack 34 is provided with a return spring 340 that abuts against the inner wall of the material trough 30.

[0038] The wear-resistant bushing 31 is slidably engaged at the bottom of the material trough 30. The wear-resistant bushing 31 has a toothed groove 310 on its side wall. The end of the material trough 30 is rotatably engaged with a rotating shaft 35. One end of the rotating shaft 35 is connected to a small gear 350 that meshes with the toothed groove 310.
