[0019] (3) Under the driving action of the stirring component, the fluids in the first reaction chamber and the second reaction chamber form a cycle, which can repeatedly mix and fully react, greatly increasing the sedimentation effect of water treatment. The fine impurities in the raw water are adsorbed and flocculated after contacting the mud residue in the muddy water, and the first sedimentation is achieved through precipitation; when the third mixed fluid flows through the inclined tube group from bottom to top, it is partially vortexed by the resistance of the end face of the inclined tube group, which reduces the flow rate and achieves the second sedimentation; the inner cavity of the inclined tube group is provided with filter cotton, filter yarn and other structures, so as to retain solid impurities in the space below the inclined tube group as much as possible to achieve filtration. The form of two sedimentations plus one filtration greatly improves the impurity removal effect of water treatment.

[0020] (4) When the liquid level in the inner cavity of the second reaction chamber rises, the floating plate can be pushed to float, thereby driving the inclined tube group to move upward to form a fluid gap between the inclined tube group and the conical surface. The fluid gap is used to improve the water permeability at the position of the inclined tube group to alleviate the blockage problem, so as to reduce the rising speed of the liquid level in the inner cavity of the second reaction chamber, realize emergency treatment, reduce the severity of sewage leakage, and provide time for maintenance work of users.

[0039] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0040] Reference Figure 1 to Figure 3The present embodiment provides an integrated mechanical stirring and clarifying device, comprising a housing 1, a first reaction chamber 2, and a second reaction chamber 3 sleeved on the outer periphery of the first reaction chamber 2; the first reaction chamber 2 and the second reaction chamber 3 are both longitudinally arranged in the inner cavity of the housing 1. The first reaction chamber 2 and the second reaction chamber 3 are connected by a plurality of connecting rods, the two ends of the connecting rods are respectively fixedly connected to the outer wall of the first reaction chamber 2 and the inner wall of the second reaction chamber 3 (for example, fixedly connected by bolts), the connecting rods are arranged along the radial direction of the first reaction chamber 2, and the plurality of connecting rods are arranged in a circumferential array on the outer wall of the first reaction chamber 2, thereby ensuring the connection stability of the first reaction chamber 2 and the second reaction chamber 3.

[0041] Reference Figure 1 to Figure 3 The first reaction chamber 2 is provided with a first reaction chamber 20 with both top and bottom being open, and the first reaction chamber 20 is used to achieve the first sedimentation. The first reaction chamber 20 is a columnar structure.

[0042] Reference Figure 1 to Figure 3 A second reaction chamber 30 with openings at the top and bottom is provided between the second reaction chambers 3 . The second reaction chamber 30 is an annular structure and is used to communicate with the first reaction chamber 20 to form a circulating water circuit.

[0043] Reference Figure 1 to Figure 3 A separation chamber 10 is provided between the shell 1 and the reaction chamber; the separation chamber 10 is used to achieve the second sedimentation.

[0044] Reference Figure 1 to Figure 3 The top of the first reaction chamber 20 is connected to the top of the second reaction chamber 30, and the bottom of the first reaction chamber 20, the bottom of the second reaction chamber 30 and the bottom of the separation chamber 10 are connected in a mountain shape.

[0045] Reference Figure 1-2 , Figure 8 and Fig. 9 The integrated mechanical stirring and clarification equipment also includes a stirring and scraping machine 4 arranged in the inner cavity of the shell 1. The stirring and scraping machine 4 includes a stirring component and a scraping component. The stirring component is arranged at the bottom of the first reaction chamber 2, and the scraping component is arranged at the bottom of the inner cavity of the shell 1. The stirring component includes a rotatable stirring impeller 41, which lifts the bottom muddy water into the first reaction chamber 20 to mix the muddy water with the raw water; the fine impurities in the raw water are adsorbed and flocculated after contacting the mud residue in the muddy water, and solid-liquid separation (i.e., the first sedimentation) is achieved through precipitation; during the solid-liquid separation process, part of the solid sinks to the bottom surface of the inner cavity of the shell 1, and part of the solid mixes with the liquid to form a first mixed fluid and flows upward. The scraping component includes a rotatable rotating beam 42, and a plurality of scrapers 43 are arranged below the rotating beam 42. The scrapers 43 can push the mud in the inner cavity of the shell 1 into the second mud bucket 16. The stirring and scraping machine 4 is a conventional existing technology in the industry, and the specific structure will not be repeated.

[0046] Reference Figure 1 to Figure 3 , an inclined tube group 13 and a water collecting tank 14 are installed in the inner cavity of the shell 1. When the third mixed fluid flows through the inclined tube group 13 from bottom to top, it is subject to the resistance of the end face of the inclined tube group 13 to generate partial vortexes, which reduces the flow rate and causes some solid impurities in the third mixed fluid to settle (i.e., the second sedimentation). The inner cavity of the inclined tube group 13 is provided with structures such as filter cotton and filter yarn, so as to retain solid impurities in the space below the inclined tube group 13 as much as possible. The inclined tube group 13 includes a plurality of inclined tubes arranged obliquely, and the inclined tubes are arranged in a square continuous shape and form a shape that can adapt to fill the separation chamber 10. Adjacent inclined tubes are fixedly connected by clamps, frame structures, etc.

[0047] Reference Figure 2 and Figure 3 The inclined tube group 13 is located in the middle and upper part of the separation chamber 10, and the water collecting tank 14 is located at the top of the separation chamber 10 and above the inclined tube group 13. The water collecting tank 14 is a tank structure with an open top surface. The liquid level of the fluid in the separation chamber 10 gradually rises and submerges the side wall of the water collecting tank 14, thereby flowing into the water collecting tank 14, but the impurities in the fluid in the separation chamber 10 cannot pass over the side wall of the water collecting tank 14 due to their own weight, thereby achieving the interception of impurities.

[0048] Reference Figure 2 , Figure 4 and Figure 5 The water collecting tank 14 includes an annular water collecting tank 141 and / or a radiation water collecting tank 142 .

[0049] Reference Figure 1 to Figure 3 The middle and lower part of the side wall of the first reaction chamber 2 is connected with a water inlet pipe 201, which penetrates the separation chamber 10 and the second reaction chamber 30 and communicates with the first reaction chamber 20. The water inlet pipe 201 is plugged into the housing 1, the first reaction chamber 2 and the second reaction chamber 3, respectively, and is sealed and fixedly connected at the plug-in position (for example, fixed and sealed by welding or a sealing ring).

[0050] Reference Figure 1 to Figure 3 The water collecting tank 14 is connected to and communicated with a water outlet pipe 1401 , and the treated water is discharged through the water collecting tank 14 and the water outlet pipe 1401 .

[0051] Reference Figure 1 to Figure 3 A first mud bucket 15 is provided at the inner wall of the housing 1. The first mud bucket 15 is located at the outer edge of the separation chamber 10 (for example, fixed by welding or bolts). The first mud bucket 15 is located below the inclined tube group 13 and is used to immediately discharge the impurities obtained by the second sedimentation. The first mud bucket 15 is connected and communicated with a venting pipeline 1501 to discharge the impurities obtained by the second sedimentation; or the middle and upper part of the present invention is vented, and the impurities accumulate in the middle and lower part of the inner cavity of the housing 1. At this time, starting the scraper assembly can discharge the accumulated impurities.

[0052] Reference Figure 1 to Figure 3 A second mud bucket 16 is provided at the center of the bottom surface of the inner cavity of the housing 1, and the second mud bucket 16 is located below the rotation center of the scraper assembly; the second mud bucket 16 is connected and communicated with an emptying pipeline 301. The scraper assembly pushes the impurities accumulated on the bottom surface of the inner cavity of the housing 1 into the second mud bucket 16, and then the impurities are discharged through the emptying pipeline 301.

[0053] Reference Figure 1 to Figure 3 , the top of the first reaction chamber 2 is lower than the top of the second reaction chamber 3, and the top of the water collecting tank 14 is lower than the top of the second reaction chamber 3. Since the first reaction chamber 20, the second reaction chamber 30 and the separation chamber 10 are interconnected, the liquid levels inside and outside the second reaction chamber 3 are usually consistent. In order to avoid the mixing of liquid inside and outside the top of the second reaction chamber 3, the height of the top of the first reaction chamber 2 and the height of the top of the water collecting tank 14 are required to be lower than the height of the second reaction chamber 3 (the height of the liquid level outside the second reaction chamber 3 is flush with the height of the top of the water collecting tank 14).

[0054] Reference Figure 2 A mounting platform 11 (for example, formed by a stainless steel plate and a stainless steel frame connected to each other by bolts) is provided at the top of the inner cavity of the housing 1, and both ends of the mounting platform 11 are respectively connected to the inner wall or the top of the housing 1 (for example, detachably connected by bolts). A driving mechanism 12 connected to the stirring and scraping machine 4 is installed on the mounting platform 11; the driving mechanism 12 includes a plurality of driving motors, which are fixedly mounted on the upper surface of the mounting platform 11 by bolts. The driving mechanism 12 is connected to the stirring assembly and the scraping assembly through a driving shaft and / or a waterproof wire.

[0055] Reference Figure 4 The cross sections of the first reaction chamber 2 and the second reaction chamber 3 are both circular.

[0056] Reference Figure 5 and Figure 6 To facilitate the installation of the inclined tube, the cross-section of the upper portion of the first reaction chamber 2 is square and the cross-section of the lower portion is circular; the cross-sections of the upper and lower portions of the second reaction chamber 3 are both square.

[0057] Reference Figure 7 A walkway board 101 is provided at the top of the outer wall of the housing 1 (for example, fixedly connected by bolts and a support frame), and a user standing on the walkway board 101 can perform operations such as sampling, observation, and garbage salvage of the fluid in the inner cavity of the housing 1. A staircase 102 is provided on the outer side of the walkway board 101; since there are usually several integrated mechanical stirring and clarification devices and they are arranged adjacent to each other, the user can walk to different integrated mechanical stirring and clarification devices via the staircase 102, thereby increasing the convenience of operation.

[0058] Reference Figure 2 , Figure 3 and Fig.10, the annular water collecting trough 141 is arranged on the inner wall of the shell 1, and the radiation water collecting trough 142 is arranged in a divergent shape between the second reaction chamber 3 and the annular water collecting trough 141, the annular water collecting trough 141 and the radiation water collecting trough 142 are connected to each other (for example, fixedly connected by bolts or fixedly connected by welding) and communicated, and the annular water collecting trough 141 is connected to the water outlet pipeline 1401, so as to achieve water outlet. The annular water collecting trough 141 is a plate-like structure with a U-shaped cross section, and the radiation water collecting trough 142 is a plate-like structure with a U-shaped cross section. The annular water collecting trough 141 is fixedly connected to the mounting platform 11 or the shell 1 (for example, fixedly connected by bolts or fixedly connected by welding); when the annular water collecting trough 141 is connected to the mounting platform 11, when the user lifts the mounting platform 11 upward, the water collecting trough 14 can be driven to be drawn out from the inner cavity of the shell 1, so as to facilitate the inspection and cleaning of the present invention.

[0059] Reference Figure 2 The top of the second reaction chamber 3 is connected to the mounting platform 11 (for example, fixedly connected by bolts). When the user lifts the mounting platform 11 upward, the first reaction chamber 2 and the second reaction chamber 3 can be pulled out from the inner cavity of the shell 1 to facilitate the inspection and cleaning of the present invention.

[0060] Reference Figure 2 and Figure 3 Since the first reaction chamber 20, the second reaction chamber 30 and the separation chamber 10 are interconnected at the bottom, the liquid levels inside and outside the second reaction chamber 3 are generally the same. However, the inclined rod group has a filtering effect on impurities. The continuous accumulation of impurities at the position of the inclined rod group will cause the water permeability of the inclined rod group to drop significantly, further causing the height of the liquid level inside the second reaction chamber 3 to continue to rise; when the height of the liquid level inside the second reaction chamber 3 is higher than the top of the second reaction chamber 3, the sewage will flow into the top of the separation chamber 10 and the water collection tank 14, and then be discharged through the outlet pipe 1401 (further polluting the water that has been treated and stored before), causing a sewage leakage accident.

[0061] To avoid such problems, refer to Fig.11A floating plate 17 is provided in the inner cavity of the outer shell 1. The floating plate 17 is a low-density waterproof material (such as a hollow plastic shell, a plastic shell filled with foam, a wooden board, etc.). The floating plate 17 is arranged at the liquid level position at the top of the inner cavity of the second reaction chamber 3. The floating plate 17 can rise and fall synchronously with the change of the liquid level height at the top of the inner cavity of the second reaction chamber 3; the floating plate 17 and the inclined tube group 13 are fixedly connected by an N-shaped pull rod 171 (for example, fixedly connected by bolts), and the top of the inner cavity of the second reaction chamber 3 is inserted into the N-shaped pull rod 171, so that the heights of the liquid level at the top of the inner cavity of the second reaction chamber 3, the floating plate 17, the pull rod 171 and the inclined tube group 13 change synchronously. A conical surface 302 is provided on the upper part of the side wall of the first reaction chamber 2, and the inclined tube group 13 is sleeved and crimped (by its own weight) on the conical surface 302; when the liquid level in the inner cavity of the second reaction chamber 3 rises, it can push the floating plate 17 to float up, thereby driving the inclined tube group 13 to move upward to form a fluid gap between the inclined tube group 13 and the conical surface 302. The fluid gap is used to improve the water permeability at the position of the inclined tube group 13, thereby alleviating the blockage problem, so as to reduce the rising speed of the liquid level in the inner cavity of the second reaction chamber 3, realize emergency treatment, and reduce the severity of sewage leakage (compared with the water at the top of the inner cavity of the second reaction chamber 3, the water quality in the middle of the separation chamber 10 is better), thereby providing time for the maintenance work of the users.

[0062] A water treatment method, using an integrated mechanical stirring clarification device to clarify sewage, the steps comprising:

[0063] S1, raw water is injected into the first reaction chamber 20 through the water inlet pipeline 201; the injection of raw water adopts a liquid pump or its own weight to provide pressure;

[0064] S2, the raw water is mixed with the lifted muddy water in the first reaction chamber 20 to obtain a first mixed fluid, and the first mixed fluid rises under the driving action of the stirring component and overflows into the second reaction chamber 30; the stirring component has the function of stirring and mixing the raw water and the muddy water at the same time;

[0065] S3, the first mixed fluid descends along the second reaction chamber 30;

[0066] S4. At the bottom opening of the second reaction chamber 30, the first mixed fluid is divided into a second mixed fluid and a third mixed fluid; the second mixed fluid is mixed with muddy water and lifted into the first reaction chamber 20 to form a circulation; the third mixed fluid flows through the inclined tube group 13 and the water collecting tank 14 in the separation chamber 10 and is discharged.

[0067] The present invention also includes an electrical cabinet, which is fixedly mounted on the upper surface of the mounting platform 11 by bolts; the drive motor is connected to the electrical cabinet by wires and signal lines; the electrical cabinet is connected to an external power supply and an external computer by wires and signal lines respectively, and the computer controls the start and stop of the drive motor in the present invention through the electrical cabinet.

[0068] The present invention has a simple structure and reliable functions. The integrated design reduces the complexity of its own structure, reduces the complex components required for traditional mechanical stirring clarifiers, and improves the stability and durability of the structure. At the same time, the present invention can effectively reduce the environmental requirements for the construction site and simplify the steps of on-site construction, reduce the difficulty of construction, thereby shortening the construction period and reducing construction costs. The present invention has high adaptability and can effectively treat various municipal water sources, including but not limited to river water, lake water and groundwater.
