Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and more specifically, to an energy-saving sewage recycling treatment device. Background Art

[0002] An energy-saving sewage recycling treatment device is an integrated system that combines various sewage treatment technologies. Through multiple methods such as physical and chemical means, it purifies sewage to meet discharge standards or reuse requirements. This device focuses on energy conservation and consumption reduction, adopts an advanced automatic control system, reduces manual intervention, and improves operating efficiency.

[0003] With the rapid economic development of our country, the problem of water pollution is becoming increasingly serious, and sewage treatment has become an important topic in environmental protection. In the process of sewage treatment, an energy-saving sewage recycling treatment device plays a crucial role. However, there are some problems in the existing technology during the sewage treatment process that need to be solved urgently. First, in the existing technology, sewage often directly enters the subsequent treatment links without preliminary filtration, which causes a large number of suspended particles and impurities to directly enter the treatment equipment, easily resulting in equipment blockage, increasing maintenance costs, and reducing treatment efficiency. The lack of preliminary filtration not only increases the burden on the subsequent treatment equipment but also shortens the service life of the equipment. Second, the subsequent filtration path in the existing technology is often single. Once it is blocked or damaged, it will seriously affect the efficiency of sewage treatment. In addition, the single filtration path also limits the improvement of treatment capacity and is difficult to meet the needs of large-scale sewage treatment. At the same time, the sludge generated from sewage treatment is inconvenient to clean. Summary of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] Embodiment:

[0027] Please refer to Figure 1 、 Figure 2 , an energy-saving sewage recycling treatment device, including a sedimentation tank 1 and a flocculation tank 2 integrally formed with the sedimentation tank 1, and a water conveyance mechanism 3 is installed at the connection of the side walls of the sedimentation tank 1 and the flocculation tank 2. Two protection plates 11 are integrally made on both sides of the surface of the sedimentation tank 1; a chemical agent injection tank 21 and an aeration pipe 22 are provided on the surface of the flocculation tank 2; the water conveyance mechanism 3 includes a water pump 31 and two pipelines 32.

[0028] Among them, the sedimentation tank 1 carefully selects corrosion-resistant stainless steel as the core material. This choice not only ensures the firm and durable structure of the tank body, but also effectively resists various corrosive factors that may exist in the sewage environment, extending the service life of the equipment. The main function of the sedimentation tank 1 is to conduct preliminary physical treatment of the sewage. Through the natural law of gravity, it guides the suspended particles and heavier impurities in the sewage to slowly settle to the bottom of the tank, gradually accumulating to form a sludge layer. At the same time, the relatively clean water naturally rises to form a clear clear water layer, laying a solid foundation for the subsequent more refined sewage treatment process. This process is not only energy-efficient, but also significantly improves the overall efficiency and effect of sewage treatment.

[0029] Among them, the flocculation tank 2 plays a crucial role. When the sewage preliminarily treated in the sedimentation tank 1 enters the flocculation tank 2, the control system will automatically adjust the opening time and opening degree of the solenoid valve in the chemical agent injection tank 21 according to the preset parameters or the water quality data monitored in real time, and inject an appropriate amount of flocculant into the flocculation tank 2. At the same time, the aeration pipe 22 starts to work, introducing compressed air into the tank to produce a uniform aeration effect. Under the combined action of the chemical agent and aeration, the tiny suspended particles in the sewage quickly aggregate to form larger flocs, and gradually settle to the bottom of the tank under the action of gravity. As time goes by, the clear water layer gradually rises, and the flocculation effect becomes more and more obvious. Finally, the sewage treated by flocculation will enter the next stage of the treatment process.

[0030] Among them, the water conveyance mechanism 3 is responsible for conveying sewage from one place to another. When the system receives a start signal, the water pump 31 starts to work, and its pumping end extracts the sewage preliminarily treated in the sedimentation tank 1. Under the push of the water pump 31, the sewage is conveyed to the flocculation tank 2 through the pipeline 32. In this process, the design of the pipeline 32 should ensure that the sewage can flow smoothly, avoiding excessive resistance or eddy currents, which may affect the water conveyance efficiency. When the flocculation tank 2 finishes processing or another batch of sewage needs to be processed, the system can achieve continuous or intermittent conveyance of sewage by controlling the start and stop of the water pump 31 and switching the connection direction of the pipeline 32. At the same time, the rotation speed and flow rate of the water pump 31 can also be adjusted to meet the requirements of different treatment stages.

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 For an energy-saving sewage recycling treatment device, two cleaning ports 4 are provided on the side walls of the sedimentation tank 1 and the flocculation tank 2. Two flange connecting pipes are respectively provided at the two cleaning ports 4, and two sealing plates 5 are locked. Above the sedimentation tank 1, a debris filtering mechanism 6 is installed. At both sides of one end of the flocculation tank 2, two connectors 7 are seamlessly welded respectively. At the outer ends of the two connectors 7, two sewage filtering mechanisms 8 are respectively flange-connected. At the outer ends of the two sewage filtering mechanisms 8, a control mechanism 9 is installed. At both ends of the outer wall of the sealing plate 5, two handles 51 are welded respectively; the debris filtering mechanism 6 includes two side plates 61, an outer plate 62, an inclined plate 63, a grille 64 and two angle irons 65; the sewage filtering mechanism 8 includes a housing 81, multiple filter meshes 82 and multiple activated carbon adsorption plates 83; the control mechanism 9 includes two connecting pipes 91, two switching valves 92 and a three-way pipe 93.

[0032] Among them, two cleaning ports 4 are cleverly opened on the side walls of the sedimentation tank 1 and the flocculation tank 2. These cleaning ports 4 are not only reasonably located, but also equipped with flange pipes, forming a perfect matching mechanism with the sealing disk 5. This innovative design greatly facilitates the regular cleaning and maintenance of the sludge accumulated in the sedimentation tank 1 and the flocculation formed in the flocculation tank 2. When the system needs to enter the maintenance or overhaul stage, especially for deep cleaning of the sedimentation tank 1 and the flocculation tank 2, the disassembly and installation process of the sealing disk 5 becomes extremely simple. The operator only needs to easily hold the handles 51. These handles 51 are not only sturdy and durable, but also have anti-slip pads attached to their surfaces, which effectively prevent operational errors caused by wet hands or slipping gloves, ensuring the stability and safety of the entire process. Through simple rotation or push-pull actions, the sealing disk 5 can quickly and smoothly detach from the flange pipe, exposing the cleaning port 4, so that the cleaning work can be carried out smoothly. This design not only simplifies the operating process, but also significantly improves work efficiency, because operators can independently complete the removal, transportation and reinstallation of the sealing disk without the help of any additional tools or equipment, which greatly reduces labor intensity and shortens the maintenance cycle.

[0033] Among them, the debris filtering mechanism 6 plays a vital role. It can effectively intercept and remove larger solid debris in sewage and protect subsequent treatment units from blockage and wear. The side plate 61 is not only required to have sufficient strength to withstand the impact of sewage and the weight of debris, but also needs to have good corrosion resistance. The outer plate 62 is wrapped around the outside of the side plate 61 to form the outer contour of the debris filtering mechanism 6 and enhance the stability of the overall structure. The inclined plate 63 is designed to be inclined, which helps to guide the debris in the sewage to flow downward along the inclined surface and concentrate on the grid net 64 for filtration. The grid net 64 is installed at the inner bottom of the debris filtering mechanism 6, and its aperture size is carefully selected according to the processing requirements to ensure that it can effectively intercept debris without excessively hindering the flow of sewage. The grid net 64 is firmly connected to the side plate 61 and the outer plate 62 by welding to form a complete filtering surface. The triangle iron 65 is used as a reinforcing rib, and the opposite ends of the two triangle irons 65 are respectively welded to the separated ends of the two side plates 61, which further enhances the overall strength and stability of the filtering mechanism. The debris filtering mechanism 6 is designed as a funnel-shaped frame and is firmly inserted into the inner top of the sedimentation tank 1. When sewage flows into the sedimentation tank 1 from above, it will first pass through the debris filtering mechanism 6. Under the guidance of the inclined plate 63, large pieces of debris in the sewage are effectively intercepted on the grid mesh 64, while the clean sewage continues to flow downward through the pores of the grid mesh 64 and enters the sedimentation tank 1 for subsequent treatment. This design not only improves the filtration efficiency of the sewage treatment system, but also reduces the burden on the subsequent treatment unit and extends the service life of the system. At the same time, since all components are connected by seamless welding technology, the sealing and stability of the filtering mechanism are ensured, and the problems of sewage leakage and debris escape are effectively prevented.

[0034] Among them, the sewage filtering mechanism 8 is a key link to ensure that the water quality is further improved. Both ends of the outer shell 81 are designed with flange connection interfaces, and one end is connected to the outer end flange of the connector 7 so as to be connected to the flocculation box 2. The sewage first enters the outer shell 81 of the sewage filtering mechanism 8 through the connector 7. Under the layer-by-layer interception of the multi-layer filter mesh 82, impurities such as suspended matter and particulate matter in the sewage are effectively removed. Subsequently, the sewage that has undergone preliminary purification enters the multi-layer activated carbon adsorption disk 83 area, and under the adsorption action of the activated carbon, harmful substances such as organic matter and residual chlorine are further removed. Finally, the clean water that has undergone deep filtration and adsorption treatment flows out through the control mechanism 9 and enters the next stage of treatment or is directly discharged.

[0035] Among them, the control mechanism 9 is responsible for adjusting the working state of the two sewage filtering mechanisms 8. The two ends of the connecting pipe 91 are connected to the sewage filtering mechanism 8 and the switch valve 92 by flange connection. This connection method not only ensures the sealing, but also facilitates disassembly and maintenance. The clean water treated by the two sewage filtering mechanisms 8 enters the control mechanism 9 through their respective connecting pipes 91. The operator can determine the flow direction of the sewage by controlling the open or closed state of the switch valve 92 according to actual needs. When it is necessary to use two sewage filtering mechanisms 8 at the same time, the two switch valves 92 can be opened at the same time to discharge the sewage through the three-head pipe 93. Conversely, when only the sewage filtering mechanism 8 is required to work, it is only necessary to close the switch valve 92 in the corresponding direction. In addition, the other end of the three-head pipe 93 is designed to extend outward, which is convenient for connection with subsequent discharge pipes or other processing units. This design not only improves the flexibility of the system, but also facilitates subsequent expansion and upgrading.

[0036] Working principle of the energy-saving sewage recycling treatment device: During use, the sewage to be treated is pretreated through the debris filtering mechanism 6 to remove large particulate debris and suspended matter, preventing them from entering the subsequent treatment unit and causing blockages. The pretreated sewage enters the sedimentation tank 1. Under the action of gravity, suspended particles and heavier impurities gradually sink to the bottom of the tank, forming sludge. At the same time, the clear water layer gradually rises and is transported to the flocculation tank 2 through the water pump 31 and pipeline 32 of the water conveyance mechanism 3. In the flocculation tank 2, an appropriate amount of chemical agent is injected into the sewage through the chemical agent injection tank 21, and under the aeration action of the aeration pipe 22, it promotes the aggregation of fine particles to form larger flocs. These flocs gradually settle to the bottom of the tank under the action of gravity. The sewage after flocculation treatment enters the sewage filtering mechanism 8 through the connector 7. Through the filtration of the multi-layer filter screen 82 and the adsorption of the multi-layer activated carbon adsorption discs 83, pollutants such as suspended particles, organic matter, and odors are further removed, realizing the deep purification of sewage. By controlling the on-off valve 92 and the three-way pipe 93 of the control mechanism 9, the flow direction of the sewage can be flexibly controlled as needed. When one filtration path is blocked or needs maintenance, it can be quickly switched to another path to ensure the continuity and stability of sewage treatment. Finally, the purified clear water is discharged or reused through the three-way pipe 93.

[0037] It should be noted that the specific model specifications of the multi-layer filter screen 82, multi-layer activated carbon adsorption discs 83, on-off valve 92, and water pump 31 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0038] The power supply and principle of the water pump 31 are clear to those skilled in the art and will not be elaborated in detail here.

[0039] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description.
