Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sedimentation device for treating well water that facilitates the removal of sediment. Background Technology
[0002] In scenarios such as coal mines and nuclear facilities, mine water discharge exhibits significant fluctuations in water quality and quantity. Surveys show that among 42 mine water treatment plants in northern China, 65% use inclined tube / plate sedimentation tanks. However, the volume of the equalization tanks is generally insufficient, failing to meet the continuous drainage demand of 3-4 hours during off-peak electricity periods. For example, in one coal mine, insufficient equalization tank volume led to sludge accumulation, reducing the pre-sedimentation effect by 30%, which directly affected the efficiency of subsequent treatment.
[0003] Currently, sedimentation devices for well water treatment rely on traditional gravity sludge discharge systems. However, traditional gravity sludge discharge is prone to clogging due to the high viscosity and poor fluidity of the sediment. When the sludge discharge valve of the inclined tube sedimentation tank is opened, sludge tends to rise, resulting in excessive turbidity in the effluent, which further reduces the treatment efficiency of well water sediment.
[0004] Therefore, in order to address this problem, this utility model provides a sedimentation device for treating well water that facilitates the removal of sediment. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1:
[0018] Reference Figures 1-5 A sedimentation device for treating well water that facilitates sediment removal includes a sedimentation tank body 1. An inlet pipe 2 and an outlet pipe 3 are fixedly connected to the side walls of the sedimentation tank body 1. A sludge collection hopper 4 is fixedly connected to the bottom of the sedimentation tank body 1. A spiral conveying mechanism 5 is detachably installed at the bottom of the sludge collection hopper 4. The spiral conveying mechanism 5 includes a connecting pipe 52 detachably installed at the end of the sludge collection hopper 4. A conveying pipe 51 is fixedly connected to the end of the connecting pipe 52. A variable frequency drive motor 53 is fixedly connected to the side wall of the conveying pipe 51. A spiral blade 54 is fixedly connected to the output end of the variable frequency drive motor 53. Plate 54 is located inside the conveying pipe 51. The sedimentation tank body 1 is equipped with a spiral guide plate 11. The spiral guide plate 11 and the water inlet pipe 2 are on the same horizontal line. The bottom sludge discharge port of the sludge hopper 4 is equipped with an adjustable sludge discharge valve 41. The bottom of the sedimentation tank body 1 is equipped with an inclined sludge guide plate 42 connected to the sludge hopper 4. The surface of the inclined sludge guide plate 42 is provided with an anti-slip texture structure. The top of the sedimentation tank body 1 is equipped with a detachable top cover. Both the sedimentation tank body 1 and the top cover are cylindrical. Three sets of support feet are fixedly connected to the side of the sedimentation tank body 1. The support feet are equidistant along the side of the sedimentation tank body 1.
[0019] In this invention, during use, the inlet pipe 2 on the side of the sedimentation tank body 1 is first connected to the outlet of the storage well via a pipeline. Then, well water is transported into the sedimentation tank body 1 through the inlet pipe 2. The sediment in the sedimentation tank body 1 is used to filter the sediment in the well water. Finally, the filtered well water is discharged through the drain pipe 3. With the sludge collection hopper 4, the sediment filtered by the sedimentation tank body 1 can be collected. Then, with the screw conveyor 5, the sediment in the sludge collection hopper 4 can be discharged quantitatively at regular intervals. With the connecting pipe 52, the sediment collected in the sludge collection hopper 4 can be transported into the conveying pipe 51. Then, driven by the variable frequency drive motor 53 on the side of the conveying pipe 51, the screw blades 54 can be rotated. The screw blades 54 can evenly discharge the sediment inside the conveying pipe 51, avoiding the problem of sludge pipe blockage caused by the high viscosity and poor fluidity of the sediment in the traditional gravity sludge discharge method, and further improving the sediment treatment efficiency of the storage well water. Furthermore, the spiral guide plate 11 inside the sedimentation tank body 1 guides the water flow from the inlet pipe 2 to form a spiral flow, increasing the water flow path, extending the residence time of particles in the sedimentation tank body 1, improving sedimentation efficiency, reducing water flow short circuits, avoiding dead corners, and ensuring that all water can fully contact the sedimentation area. In addition, the inclined mud guide plate 42 promotes the sliding of sediment into the mud collection hopper 4. With the anti-slip texture on the surface of the inclined mud guide plate 42, the surface roughness of the inclined mud guide plate 42 is increased, and the anti-slip texture can increase the sliding speed of mud and sand from 0.2m / s to 0.35m / s, shortening the residence time of sediment on the mud guide plate, reducing the risk of local siltation caused by slow sliding, and the protective texture structure can suppress the eddies and secondary turbulence generated by the water flow on the surface of the inclined mud guide plate 42, maintaining the uniform sliding of sediment along the inclined direction. With the sludge discharge valve 41 on the surface of the sludge hopper 4, the interior of the sludge hopper 4 can be opened or closed or switched on and off. With the top cover on the top of the sedimentation tank body 1, the top cover can be disassembled from the sedimentation tank body 1 to maintain the interior of the sedimentation tank body 1. This disassembly method can be by screw rotation. In addition, with the setting of three sets of support feet, support force can be provided to the bottom of the sedimentation tank body 1, and the three sets of support feet are arranged in a triangle, which can greatly improve the stability support effect.
[0020] Additional information: The sludge discharge valve 41 can be connected to a PLC controller system. The PLC controller system consists of a PLC controller, a liquid level sensor, a turbidity monitoring module, and a variable frequency drive motor 53, which work together to automatically trigger the sludge discharge program. When the turbidity sensor detects that the effluent turbidity is >5 NTU, the system automatically extends the sludge discharge time or increases the speed of the spiral blades 54. When the liquid level in the sludge collection hopper is below 20%, the system automatically stops sludge discharge to save energy. Example 2:
[0021] Reference Figures 1-4 A filter box 6 is fixedly connected to the side of the sedimentation tank body 1. The filter box 6 is connected to the drain pipe 3. A multi-stage gradient filter layer 7 is installed inside the filter box 6. The multi-stage gradient filter layer 7 is composed of a primary stainless steel filter screen 71, an activated carbon adsorption layer 72, and an ultrafiltration membrane module 73 stacked in sequence. The layers can be replaced modularly through quick-connect slots. In this invention, the filter box 6 is used to install a multi-stage gradient filter layer 7, which filters out sediment in the well water, thereby transporting the filtered well water to the drain pipe 3 for discharge. The primary stainless steel filter screen 71 preferentially intercepts large suspended particles such as silt and rust, protecting the downstream fine layer; the activated carbon adsorption layer 72 adsorbs organic matter, residual chlorine, and odors, improving the taste of the water; and the ultrafiltration membrane module 73 intercepts bacteria, viruses, colloids, and other tiny impurities, ensuring that the turbidity of the effluent meets the requirements of high-precision treatment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
