Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purification equipment technology, specifically to a device for reusing clean water from sludge ponds. Background Technology
[0002] The water purification plant's purifiers automatically discharge wastewater, which is abundant and flows into a sludge tank. This wastewater then needs to be pumped to the sludge tank. When water supply is tight, directly sending the sludge-water to the sludge tank is wasteful. Furthermore, to maintain the quality of the production water, the purifiers need frequent discharges, leading to prolonged high liquid levels in the sludge tank. The sludge pumps also cannot be stopped, increasing the unit's energy consumption. Currently, the factory mainly uses sludge pumps to send sludge to a wastewater treatment plant. However, this method requires the sludge pumps to be run continuously, and it also wastes the clear water that has settled at the top of the sludge tank, especially during hot summer months, resulting in significant water loss, which contradicts the goal of energy conservation and emission reduction.
[0003] Based on the above, this utility model proposes a device for the reuse of clean water in sludge ponds, which facilitates the reuse of clean water. Utility Model Content
[0004] The main objective of this invention is to provide a device for the reuse of clean water in sludge ponds, thereby solving the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for reusing clean water from a sludge pond, comprising a first pipeline, a booster pump, and a second pipeline. A valve is installed at the outlet end of the first pipeline, and a third pipeline is provided at one end of the valve. A flexible joint is provided on the third pipeline, and a booster pump is provided at the inlet end of the third pipeline. The outlet end of the booster pump is connected to the second pipeline, and a turbidity detector is provided at the outlet end of the second pipeline.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the inlet end of the first pipeline is connected to the sludge pool, and the outlet end of the second pipeline is connected to the production water pool.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the inlet end of the first pipeline is provided with a first filter membrane, the outlet end of the second pipeline is provided with a second filter membrane, and the pore size of the second filter membrane is smaller than that of the first filter membrane.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a pressure gauge is also installed on the third pipeline.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the valve is a butterfly valve.
[0010] The beneficial effects of this invention are as follows: This device, through the arrangement of a first pipeline, a booster pump, a second pipeline, and valves, achieves the effective extraction and transportation of clean water from the sludge pool. The installation of valves allows for precise control of the water flow, while the flexible joint on the third pipeline provides flexibility and shock absorption, helping to protect the pipeline system from damage caused by mechanical stress. Furthermore, the turbidity detector at the outlet of the second pipeline can monitor water quality in real time, ensuring the safety of clean water reuse. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0013] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0016] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0017] See attached diagram. Figure 1 An apparatus for reusing clean water from a sludge pond in this embodiment includes a first pipeline 6, a booster pump 2, and a second pipeline 7. A valve 5, which is a butterfly valve, is installed at the outlet end of the first pipeline 6. A third pipeline 8 is provided at one end of the valve 5. A flexible joint 3 is provided on the third pipeline 8. The booster pump 2 is provided at the inlet end of the third pipeline 8. The outlet end of the booster pump 2 is connected to the second pipeline 7. A turbidity detector 1 is provided at the outlet end of the second pipeline 7.
[0018] Furthermore, the inlet end of the first pipeline 6 is connected to the sludge pool, and the outlet end of the second pipeline 7 is connected to the production water pool. By connecting the inlet end of the first pipeline 6 to the sludge pool and the outlet end of the second pipeline 7 to the production water pool, this device enables the direct extraction and reuse of clean water from the sludge pool, improving water resource utilization efficiency, reducing dependence on fresh water resources, and helping to save water resources and reduce production costs.
[0019] Furthermore, a first filter membrane is installed at the inlet end of the first pipe 6, and a second filter membrane is installed at the outlet end of the second pipe 7. The pore size of the second filter membrane is smaller than that of the first filter membrane. The first filter membrane at the inlet end of the first pipe 6 and the second filter membrane at the outlet end of the second pipe 7 provide a two-stage filtration system. The smaller pore size of the second filter membrane allows for more effective removal of suspended particles and impurities from the water, ensuring higher quality output water that meets the water quality requirements of the production water tank.
[0020] Furthermore, a pressure gauge 4 is installed on the third pipeline 8. The pressure gauge 4 installed on the third pipeline 8 can monitor the pressure status of the system in real time, which is crucial for maintaining the stability and safety of the entire clean water reuse device; by monitoring the pressure, potential pressure problems can be detected and resolved in a timely manner, avoiding system failure or damage.
[0021] During use, the central control personnel observe the turbidity detector readings. Once the readings are within the normal range, they notify the on-site personnel to start the booster pump 2. First, add water to the booster pump. After the pressure increases, slowly open valve 5 to send the clean water from the sludge tank into the production water tank. Once the turbidity detector 1 shows a change or the booster pump reaches a specific position, turn off the booster pump 2. After the clean water has been pumped out, the sludge pump can be started to send the sludge to the sludge station.
[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
