[0039] According to the above structural features of the present application, the embodiments of the present application are further described as follows:

[0040] Reference is made to Figures 1-3The embodiment provides an integrated mechanical stirring and clarifying device, which comprises a shell 1, a first reaction chamber 2 and a second reaction chamber 3 sleeved on the periphery of the first reaction chamber 2; the first reaction chamber 2 and the second reaction chamber 3 are longitudinally arranged in the inner cavity of the shell 1. The first reaction chamber 2 and the second reaction chamber 3 are connected through a plurality of connecting rods, the two ends of the connecting rods are fixedly connected (for example, fixedly connected through bolts) with the outer wall of the first reaction chamber 2 and the inner wall of the second reaction chamber 3 respectively, 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, so that the connection stability of the first reaction chamber 2 and the second reaction chamber 3 is ensured.

[0041] With reference to Figures 1-3 The first reaction chamber 2 is provided with a first reaction cavity 20 which is open at the top and the bottom and is used for realizing the first-time sedimentation. The first reaction cavity 20 has a columnar structure.

[0042] With reference to Figures 1-3 The first reaction chamber 2 and the second reaction chamber 3 are provided with a second reaction cavity 30 which is open at the top and the bottom and has an annular structure and is used for communicating with the first reaction cavity 20 to form a circulating water path.

[0043] With reference to Figures 1-3 The shell 1 and the reaction chambers are provided with a separation cavity 10; the separation cavity 10 is used for realizing the second-time sedimentation.

[0044] With reference to Figures 1-3 The top end of the first reaction cavity 20 communicates with the top end of the second reaction cavity 30, and the bottom end of the first reaction cavity 20, the bottom end of the second reaction cavity 30 and the bottom end of the separation cavity 10 communicate in a mountain shape.

[0045] With reference to Figures 1-2 , Figure 8 And Figure 9 The integrated mechanical stirring and clarifying device further comprises a stirring and mud scraping integrated machine 4 arranged in the inner cavity of the shell 1. The stirring and mud scraping integrated machine 4 comprises a stirring assembly and a mud scraping assembly. The stirring assembly is arranged at the bottom of the first reaction chamber 2, and the mud scraping assembly is arranged at the bottom of the inner cavity of the shell 1. The stirring assembly comprises a stirring impeller 41 which can rotate. The stirring impeller 41 lifts the mud water at the bottom to the first reaction cavity 20, so that the mud water is mixed with raw water. After the fine impurities in the raw water contact the sludge in the mud water, the fine impurities are adsorbed and flocculated, and solid-liquid separation (i.e., the first-time sedimentation) is realized through sedimentation. During the solid-liquid separation process, part of the solid sinks to the bottom surface position of the inner cavity of the shell 1, and part of the solid is mixed with the liquid to form a first mixed fluid and flows upward. The mud scraping assembly comprises a rotating cross beam 42 which can rotate. A plurality of scraper plates 43 are arranged below the rotating cross beam 42. The scraper plates 43 can push the slurry in the inner cavity of the shell 1 to flow into the second mud bucket 16. The stirring and mud scraping integrated machine 4 is a conventional prior art in the industry, and the specific structure will not be described here.

[0046] With reference toFigures 1-3 The third mixed fluid flows from bottom to top through the inclined pipe group 13, and partial vortex occurs due to the resistance of the end face of the inclined pipe group 13, so that the flow rate is reduced, and partial solid impurities in the third mixed fluid are settled (i.e., the second settlement). The inner cavity of the inclined pipe group 13 is provided with filter cotton, filter gauze and the like, so as to retain the solid impurities in the space below the inclined pipe group 13 as much as possible. The inclined pipe group 13 includes a plurality of inclined pipes arranged obliquely, and the inclined pipes are arranged in a quadrilateral continuous manner and form a shape capable of fitting the separation cavity 10. Adjacent inclined pipes are fixedly connected by using a hoop, a frame structure or the like.

[0047] Referring to Figure 2 and Figure 3 , the inclined pipe group 13 is located in the upper part of the separation cavity 10, and the water collecting tank 14 is located at the top of the separation cavity 10 and above the inclined pipe group 13. The water collecting tank 14 is a groove structure with an open top, and the fluid level in the separation cavity 10 gradually rises and submerges the side wall of the water collecting tank 14, so that the fluid flows into the water collecting tank 14, but the impurities in the fluid in the separation cavity 10 cannot overcome the side wall of the water collecting tank 14 due to their own weight, thereby achieving the retention of the impurities.

[0048] Referring to Figure 2 , Figure 4 and Figure 5 , the water collecting tank 14 includes a ring-shaped water collecting tank 141 and / or a radial water collecting tank 142.

[0049] Referring to Figures 1-3 , the lower middle part of the side wall of the first reaction chamber 2 is connected with a water inlet pipeline 201, the water inlet pipeline 201 penetrates the separation cavity 10 and the second reaction cavity 30 and communicates with the first reaction cavity 20. The water inlet pipeline 201 is inserted into the shell 1, the first reaction chamber 2 and the second reaction chamber 3 respectively, and is fixedly and sealingly connected at the insertion position (for example, fixed and sealed by welding or a sealing ring).

[0050] Referring to Figures 1-3 , the water collecting tank 14 is connected and communicated with a water outlet pipeline 1401, and the treated water is discharged through the water collecting tank 14 and the water outlet pipeline 1401.

[0051] Referring to Figures 1-3 , a first hopper 15 is arranged at the inner side wall position of the shell 1, and the first hopper 15 is arranged at the outer edge position of the separation cavity 10 (for example, fixed by welding or fixed by bolts), and the first hopper 15 is located below the inclined pipe group 13 and is used for discharging the impurities obtained by the second settlement in time. The first hopper 15 is connected and communicated with a venting pipeline 1501, so as to discharge the impurities obtained by the second settlement; or the upper part of the present application is vented, and the impurities accumulate in the middle and lower parts of the inner cavity of the shell 1, and at this time, the accumulated impurities can be discharged by starting the mud scraping assembly.

[0052] Referring toFigures 1-3 A second hopper 16 is provided at the center of the bottom surface of the inner cavity of the housing 1 and is located below the rotation center of the scraper assembly. The second hopper 16 is connected to and communicates with a drain line 301. The scraper assembly pushes impurities accumulated on the bottom surface of the inner cavity of the housing 1 into the second hopper 16, and the impurities are then discharged through the drain line 301.

[0053] Reference Figures 1-3 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 the same. To prevent the liquids inside and outside the top of the second reaction chamber 3 from mixing, the height of the top of the first reaction chamber 2 and the height of the top of the water collecting tank 14 must 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 (e.g., formed from a stainless steel plate and a stainless steel frame bolted together) is provided at the top of the inner cavity of the housing 1. Both ends of the mounting platform 11 are removably connected to the inner wall or top of the housing 1 (e.g., by bolts). Mounted on the mounting platform 11 is a drive mechanism 12 connected to the agitator and scraper 4. This drive mechanism 12 includes several drive motors, which are bolted to the top surface of the mounting platform 11. The drive mechanism 12 is connected to the agitator and scraper assemblies via a drive shaft and / or waterproof wires.

[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 part of the first reaction chamber 2 is square and the cross-section of the lower part is circular; the cross-sections of the upper and lower parts 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 (e.g., fixedly connected to the support frame by bolts). Users standing on walkway board 101 can perform operations such as sampling, observing, and salvaging the fluid within the inner cavity of the housing 1. A staircase 102 is provided on the outer side of walkway board 101. Since multiple integrated mechanical agitation and clarification devices are typically located adjacent to each other, users can use staircase 102 to walk to different integrated mechanical agitation and clarification devices, thereby increasing operational convenience.

[0058] Reference Figure 2 、 Figure 3 and Figure 10, the annular water collecting tank 141 is arranged at the inner side wall position of the shell 1, the radial water collecting tank 142 is arranged between the second reaction chamber 3 and the annular water collecting tank 141 in a diverging manner, the annular water collecting tank 141 and the radial water collecting tank 142 are connected to each other (for example, fixedly connected by bolts or fixedly connected by welding) and communicated, the annular water collecting tank 141 is communicated with the water outlet pipeline 1401, so as to realize water outlet. The annular water collecting tank 141 is a plate structure with a U-shaped cross section, and the radial water collecting tank 142 is a plate structure with a U-shaped cross section. The annular water collecting tank 141 is fixedly connected (for example, fixedly connected by bolts or fixedly connected by welding) with the mounting platform 11 or the shell 1; when the annular water collecting tank 141 is connected with the mounting platform 11, the user can lift the mounting platform 11 upward, so as to drive the water collecting tank 14 to be extracted from the inner cavity of the shell 1, so as to facilitate the maintenance and cleaning of the application.

[0059] With reference to Figure 2 , the second reaction chamber 3 is connected (for example, fixedly connected by bolts) with the mounting platform 11, and when the user lifts the mounting platform 11 upward, the first reaction chamber 2 and the second reaction chamber 3 can be extracted from the inner cavity of the shell 1, so as to facilitate the maintenance and cleaning of the application.

[0060] With reference to Figure 2 and Figure 3 , since the first reaction cavity 20, the second reaction cavity 30 and the separation cavity 10 are communicated with each other at the bottom, the liquid level inside and outside the second reaction chamber 3 is consistent under normal circumstances. However, the inclined rod group has a filtering effect on impurities, and the continuous accumulation of impurities at the position of the inclined rod group will cause the water permeability of the inclined rod group to decrease significantly, further causing the height of the liquid level inside the second reaction chamber 3 to rise continuously; when the height of the liquid level inside the second reaction chamber 3 exceeds the top end of the second reaction chamber 3, sewage will flow into the top end of the separation cavity 10 and the water collecting tank 14, and then be discharged through the water outlet pipeline 1401 (further polluting the water that has been treated and stored), causing sewage leakage accident.

[0061] To avoid such problems, with reference to Figure 11The inner cavity of the shell 1 is provided with a floating plate 17 made of low-density waterproof material (for example, a hollow plastic shell, a plastic shell filled with foam inside, a wooden board, etc.), which is arranged at the liquid surface position at the top end of the inner cavity of the second reaction chamber 3 and can rise and fall synchronously with the change of the liquid surface height at the top end of the inner cavity of the second reaction chamber 3; the floating plate 17 is fixedly connected with the inclined pipe group 13 through an n-shaped pull rod 171 (for example, fixedly connected through bolts), and the top end 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 top end of the inner cavity of the second reaction chamber 3, the floating plate 17, the pull rod 171 and the inclined pipe group 13 change synchronously. The upper part of the side wall of the first reaction chamber 2 is provided with a conical surface 302, and the inclined pipe group 13 is sleeved and (relying on its own weight) press-fitted on the conical surface 302; when the liquid surface of the inner cavity of the second reaction chamber 3 rises, the floating plate 17 can be pushed to float upwards, thereby driving the inclined pipe group 13 to move upwards to form a fluid gap between the inclined pipe group 13 and the conical surface 302, the fluid gap is used to improve the water permeability at the position of the inclined pipe group 13 to slow down the clogging problem, thereby reducing the rising speed of the liquid surface of the inner cavity of the second reaction chamber 3, realizing emergency treatment, reducing the severity of sewage leakage (compared with the water at the top end of the inner cavity of the second reaction chamber 3, the water quality in the middle part of the separation chamber 10 is better), thereby providing time for the maintenance operation of the user.

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

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

[0066] S4, at the opening position at the bottom end 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 lifted to the first reaction chamber 20 after being mixed with the sludge to form a cycle; the third mixed fluid flows through the inclined pipe group 13 and the water collecting tank 14 in the separation chamber 10 and is then discharged.

[0067] The application also includes an electrical cabinet, which is fixedly installed on the upper surface of the installation platform 11 through bolts; the driving motor is connected with the electrical cabinet through wires and signal lines; the electrical cabinet is connected with an external power supply and an external computer through wires and signal lines, respectively, and the computer controls the start and stop of the driving motor in the application through the electrical cabinet.
