Description

Technical Field

[0001] The utility model relates to the technical field of sand-water separation, in particular to a bottom sediment sand-water separation device of a waterworks. Background Art

[0002] In the production process of water plants, the treatment of sediment is an important link to ensure water quality safety and stable operation of equipment. Sediment is mainly composed of suspended particles, sediment, organic matter and other deposits in the water body. The presence of large-diameter sand and gravel is not only easy to block the pipes, but also may cause serious wear and tear on the equipment, thus affecting the production efficiency and water supply quality of the entire water plant.

[0003] At present, water plants usually use static sedimentation or simple mechanical filtration methods to treat bottom mud. However, these methods are often ineffective when treating bottom mud containing large-diameter sand and gravel. The static sedimentation method takes a long time and has poor removal effect on large-diameter sand and gravel, while the mechanical filtration method easily loses its filtration effect due to blockage by large-diameter sand and gravel, and requires frequent shutdown for cleaning, which reduces the operating efficiency of the equipment. Therefore, in response to the above technical problems, a bottom mud sand and water separation device for a water plant is proposed herein. Utility Model Content

The connecting plate is lifted by an external lifting mechanism and then released, so that the separation box can hit the support plate, and cooperate with the internal water flow to flush, so as to effectively screen large-diameter sand and gravel, and can avoid pipeline blockage and instrument wear. At the same time, when the connecting plate is lifted, the two groups of connecting plates can separate the tension springs, and rebound when falling and released, which can increase the descending speed of the separation box, thereby strengthening the impact and improving the screening effect.

[0014] The utility model proposes a bottom sediment and sand water separation device for a water plant.

A fixing rod 6 is fixedly connected inside the device body 1, a roller 7 is rotatably connected to the outside of the fixing rod 6, and the roller 7 and the slide groove 5 are rollingly connected, a connecting plate 9 is fixedly connected to the upper side of the separation box 3, a tensile structure is provided on one side of the connecting plate 9, a convex plate 13 is fixedly connected to the outside of the connecting plate 9, and a lifting mechanism is installed on the outside of the device body 1.

[0024] A feeding plate 8 is fixedly connected to the outside of the device body 1, and the feeding plate 8 is located above the separation box 3. Sand and water containing bottom mud can be fed into the separation box through the feeding plate 8 for separation.

[0025] The stretching structure includes a first connecting plate 10, a second connecting plate 11 and a spring 12. The first connecting plate 10 is fixedly connected to the connecting plate 9, the second connecting plate 11 is fixedly connected to the device body 1, and the spring 12 is fixedly connected to both the first connecting plate 10 and the second connecting plate 11.

[0026] The second connecting plate 11 is located directly below the first connecting plate 10 , which makes it easy to install the spring 12 .

[0027] The lifting mechanism includes a fixed plate 14, a driving motor 15, a rotating rod 16 and a butt plate 17. The fixed plate 14 is fixedly connected to the device body 1, the driving motor 15 is fixedly connected to the fixed plate 14, the rotating rod 16 is fixedly connected to the driving motor 15, and the rotating rod 16 is rotatably connected to the fixed plate 14, the butt plate 17 is fixedly connected to the rotating rod 16, and the butt plate 17 is in contact with the convex plate 13.

[0028] The outside of the device body 1 is fixedly connected with a discharge pipe 18, and the discharge pipe 18 is close to the bottom of the device body 1. The sand and water screened out with large-diameter sand and gravel can be discharged for processing through the discharge pipe 18.

[0029] The working principle of a bottom sediment and sand water separation device of a water plant based on the embodiment is that when it is used, sand and water containing bottom sediment are fed into the separation box 3 through the feeding plate 8, and then the driving motor 15 is operated through the external lifting mechanism, so that the rotating rod 16 drives the abutment plate 17 to rotate, thereby the convex plate 13 can be lifted up, driving the connecting plate 9 to rise, and the separation box 3 can be lifted together until the abutment plate 17 is separated from the convex plate 13, and the separation box 3 can be released, so that the separation box 3 collides with the support plate 2 under the action of its own gravity and the bottom sediment and sand and gravel in the box. This collision process, in conjunction with the action of internal water flow scouring, can effectively screen the larger diameter sand and gravel in the sand and water to the top of the screen 4, thereby avoiding large diameter The blockage and wear of pipes and equipment by sand and gravel. In addition, when the connecting plate 9 is lifted, the first connecting plate 10 will be separated from the second connecting plate 11, thereby stretching the spring. When the separation box 3 is released and falls, the spring 12 will cooperate with the rebound to increase the descending speed, thereby enhancing the impact strength and improving the screening effect and rate. Finally, in order to ensure the stability and accuracy of the separation box 3 during the lifting process, the pulley installed inside the device body 1 rolls in the slide groove 5 opened outside the separation box 3. On the one hand, it can promote the lifting and lowering movement of the separation box 3, and on the other hand, it can also play a limiting role to avoid displacement or deflection of the separation box 3 during the lifting process, thereby ensuring the smooth progress of the entire separation process.
