Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a flocculation sedimentation device for sewage treatment. Background Technique

[0002] The ABS corrugated flocculation sedimentation device plays a key role in the water treatment process. Its core lies in the efficient integration of physical and chemical flocculation technologies, as well as the innovative lateral flow sedimentation mechanism. The raw water is first mixed with an appropriate amount of flocculant and achieves full contact through mechanical or hydraulic action in the mixing tank. The flocculant quickly acts on the suspended solids and colloidal particles in the water to form larger flocs. Subsequently, these flocs enter the corrugated plate area inside the ABS device. Its unique waveform design induces micro-vortices and turbulent flows in the water, greatly promoting the collision and aggregation between flocs and accelerating the growth of flocs. The corrugated plates in the device not only promote flocculation but also are cleverly arranged obliquely to construct a lateral flow sedimentation area. The water flow forms a lateral flow under the guidance of the corrugated plates, which not only expands the sedimentation area but also prolongs the sedimentation time, enabling the floc particles to smoothly settle along the corrugated plates under the action of gravity and forming a clear mud-water interface.

[0003] In the face of the treatment of high-concentration and high-viscosity sewage, the ABS corrugated flocculation sedimentation device is prone to serious clogging problems. Suspended solid particles tightly adhere to the surface of the corrugated plates and accumulate into an impermeable clogging layer, significantly reducing the effective flocculation area and limiting the space for floc formation. The clogging also blocks the water flow channel, slows down the flow rate, destroys the ideal turbulent flow state, reduces the particle collision opportunities, thereby reducing the flocculation efficiency and sedimentation quality. If not treated in time, the clogging will intensify, affecting the overall performance of the system and even possibly causing a breakdown and shutdown, having an adverse impact on the entire sewage treatment process. Content of the Utility Model

[0004] The purpose of the utility model is to solve the clogging problem existing in the prior art, improve the overall performance and stability of the flocculation sedimentation device, and provide a strong guarantee for the efficient operation of the sewage treatment process, and a flocculation sedimentation device for sewage treatment is proposed.

[0040] This device introduces a combination of a rotating rod and a driving impeller. This design cleverly utilizes the power of the water flow in the water inlet pipe to realize an automatic rotation mechanism that does not require additional energy to drive. When water flows through the water inlet pipe, the driving impeller rotates due to the impact of the water flow, thereby driving the rotating rod to rotate axially. This self-driving system not only reduces energy consumption, but also ensures the continuous and effective operation of the device. Then, the rotation of the rotating rod is converted into a power source for the inflation component, driving it to charge high-pressure gas into the gas storage component. This conversion process realizes the conversion of water flow energy into air pressure energy, providing strong power support for subsequent cleaning work. The gas storage component serves as an intermediate storage and pressure regulating device, ensuring a stable supply of high-pressure gas, providing The reliability and stability of the system are improved. With the setting of the cleaning component, the component is interconnected with the gas storage component. After obtaining the high-pressure gas, it can reciprocate above the flocculation sedimentation tank to blow the surface of the ABS corrugated flocculation sedimentation device. This blowing method directly cleans the blockage layer, which can effectively break up and remove the adhesion on the corrugated plate to prevent the formation and accumulation of the blockage layer. Compared with the traditional cleaning method, the blowing method has higher efficiency and lower maintenance cost, and will not cause mechanical damage to the corrugated plate. In summary, by introducing the self-driven rotation system, the air pressure conversion mechanism and the efficient blowing and cleaning components, the accumulated blockage layer on the surface of the ABS corrugated flocculation sedimentation device is effectively cleaned.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0050] Combined with Figures 1-7 As shown in the figure, a flocculation sedimentation device for sewage treatment of the present invention includes a flocculation sedimentation tank 1 and a water inlet pipe 2 arranged on the flocculation sedimentation tank 1. An inlet valve is also arranged on the water inlet pipe 2. An ABS corrugated flocculation sedimentation device 3 is also arranged inside the flocculation sedimentation tank 1, and further includes:

[0051] A rotating rod 4, which penetrates through the flocculation sedimentation tank 1 and can rotate axially relative to the flocculation sedimentation tank 1;

[0052] A driving impeller 5, which is fixedly installed outside the rotating rod 4 and near the water inlet end of the water inlet pipe 2, and can drive the rotating rod 4 to rotate axially through the water flow in the water inlet pipe 2;

[0053] An inflation assembly 6, which is arranged outside the flocculation sedimentation tank 1 and is connected to the rotating rod 4;

[0054] A gas storage assembly 7, which is arranged outside the flocculation sedimentation tank 1 and is connected to the inflation assembly 6, wherein under the drive of the rotating rod 4, the inflation assembly 6 can fill high-pressure gas into the gas storage assembly 7;

[0055] A cleaning assembly 8, which is arranged on the flocculation sedimentation tank 1 and is communicated with the gas storage assembly 7, and can reciprocate above the flocculation sedimentation tank 1 to blow the clogging layer formed on the surface of the ABS corrugated flocculation sedimentation device 3 to avoid the blockage of the water flow channel.

[0056] When the ABS corrugated flocculation sedimentation device 3 needs to be cleaned, sewage first enters the mixing area of the flocculation sedimentation tank 1 through the water inlet pipe 2. The connecting valve between the mixing area and the sedimentation area is closed. At this time, the sewage will not enter the sedimentation area, and the water in the sedimentation tank is discharged through the water outlet on the flocculation sedimentation tank 1. At this time, the ABS corrugated flocculation sedimentation device 3 will be exposed outside;

[0057] During the whole process of sewage entering the flocculation sedimentation tank 1, the driving impeller 5 is fixedly installed outside the rotating rod 4 and is located near the water inlet end of the water inlet pipe 2. As the water flow passes through the water inlet pipe 2, its kinetic energy drives the driving impeller 5 to rotate, and then drives the rotating rod 4 to rotate axially relative to the flocculation sedimentation tank 1. The rotating rod 4 is connected to the air charging component 6, driving the air charging component 6 to work. The air charging component 6 uses the rotational power of the rotating rod 4 to convert mechanical energy into pneumatic energy and charge high-pressure gas into the gas storage component 7. The gas storage component 7, as a gas storage and regulating device, ensures the stable supply of high-pressure gas and provides power support for the subsequent cleaning work. The cleaning component 8 is arranged above the flocculation sedimentation tank 1 and is interconnected with the gas storage component 7. The cleaning component 8 can receive the high-pressure gas from the gas storage component 7. After receiving the high-pressure gas, the cleaning component 8 reciprocates above the flocculation sedimentation tank 1. By using the purging action of the high-pressure gas, the clogging layer accumulated on the surface of the ABS corrugated flocculation sedimentation device 3 is scattered and removed, keeping its surface clean and unobstructed, thereby avoiding the blockage of the water flow channel and ensuring the smooth progress of the flocculation sedimentation process.

[0058] In a preferred embodiment of the present invention, it can be further configured as: as Figure 3 、 Figure 4 shown; the air charging component 6 includes:

[0059] A base 61, fixedly installed on the side wall of the flocculation sedimentation tank 1;

[0060] A round rod 62, rotatably arranged on the surface of the base 61, and it can rotate axially relative to the base 61;

[0061] A driving component 63, arranged on the round rod 62 and connected to the rotating rod 4, wherein the rotating rod 4 drives the round rod 62 to rotate synchronously through the driving component 63;

[0062] An air charging cylinder 64, fixedly installed on the surface of the base 61, and the number of which is two and they are arranged in parallel;

[0063] A piston 65, arranged inside the air charging cylinder 64 and in contact with the inner wall of the air charging cylinder 64, and the piston 65 can displace vertically inside the air charging cylinder 64; and

[0064] The connecting rod assembly 66 is connected to the piston 65 at one end and to the round rod 62 at the other end. Its quantity and distribution position are adapted to the round rod 62. First of all, the base 61, as the support structure of the entire inflation assembly 6, is fixedly installed on the side wall of the flocculation sedimentation tank 1, providing a stable installation foundation for other components. The round rod 62 is rotatably arranged on the surface of the base 61 through a bearing, enabling relative axial rotation between the round rod 62 and the base 61 without generating excessive frictional resistance. The drive assembly 63, as the key component connecting the rotating rod 4 and the round rod 62, realizes synchronous rotation between the two. When the rotating rod 4 rotates under the drive of external power, the drive assembly 63 will drive the round rod 62 to rotate synchronously. The inflation cylinder 64, as the main component for generating gas, has two in number and is arranged in parallel, and is fixedly installed on the surface of the base 61. This layout helps to balance the overall force of the inflation assembly 6 and improve the inflation efficiency. The piston 65 is arranged inside the inflation cylinder 64 and is in close contact with the inner wall of the inflation cylinder 64 to form a closed space. During the rotation of the round rod 62, the piston 65 can perform vertical displacement movement inside the inflation cylinder 64. This displacement movement is realized through the connecting rod assembly 66. The connecting rod assembly 66, as the bridge connecting the piston 65 and the round rod 62, has its quantity and distribution position adapted to the round rod 62 to ensure that when the round rod 62 rotates, the rotational movement can be accurately converted into the vertical displacement movement of the piston 65. When the round rod 62 rotates, the connecting rod assembly 66 will drive the piston 65 to move up and down inside the inflation cylinder 64, thereby compressing air and realizing the inflation function. It should be further noted that the inflation cylinder 64 is integrally arranged in a cylindrical shape with a U-shaped cross-section and one end is open. In Figures 3 to 5 In order to visually represent the movement trajectory of the piston 65, half of the inflation cylinder 64 is cut open.

[0065] In a preferred embodiment of the present utility model, it can be further configured as: as Figure 3 、 Figure 4 shown; the drive assembly 63 includes:

[0066] The connecting plate 631 is fixedly installed on the surface of the base 61 and is perpendicular to the base 61. One end of the rotating rod 4 outside the flocculation sedimentation tank 1 penetrates through the connecting plate 631. A bearing is embedded in the connecting plate 631, and the connecting plate 631 and the rotating rod 4 are connected through the bearing;

[0067] The first gear 632 is fixedly installed on the outside of the rotating rod 4 and can rotate synchronously with the rotation of the rotating rod 4; and

[0068] The second gear 633 is fixedly installed on the outer side of the round rod 62 and meshes with the first gear 632. The connecting plate 631 is first fixedly installed on the surface of the base 61 and is perpendicular to the base 61. This layout ensures the stability and rigidity of the connecting plate 631, providing a solid foundation for subsequent transmission. One end of the rotating rod 4 located outside the flocculation sedimentation tank 1 penetrates through the connecting plate 631, and a bearing is embedded in the connecting plate 631, enabling the connecting of the rotating rod 4 and the connecting plate 631 through the bearing. This connection method not only ensures the free rotation of the rotating rod 4 but also reduces friction and wear. The first gear 632 is fixedly installed on the outer side of the rotating rod 4, and its position is coaxial with the rotation axis of the rotating rod 4. Therefore, when the rotating rod 4 rotates driven by external power, the first gear 632 will also rotate synchronously. The second gear 633 is fixedly installed on the outer side of the round rod 62, and its position is coaxial with the rotation axis of the round rod 62. More importantly, the second gear 633 meshes with the first gear 632, forming a gear transmission mechanism. This meshing relationship enables the second gear 633 to be driven to rotate when the first gear 632 rotates, thereby realizing the synchronous rotation of the round rod 62.

[0069] In a preferred embodiment of the present utility model, it can be further configured as: as Figure 4 、 Figure 5 shown; the connecting rod assembly 66 includes:

[0070] Two L-shaped rods 661 are respectively fixedly installed on both side ends of the round rod 62;

[0071] One end of the first connecting rod 662 is sleeved on the outer side of the L-shaped rod 661, and the number and distribution position of the first connecting rods 662 are adapted to the L-shaped rods 661;

[0072] The connecting rod 663 is fixedly installed on the outer side of the piston 65 and is arranged horizontally as a whole

[0073] The second connecting rod 664, one end of which is sleeved outside the connecting rod 663, and the other end of which is hinged to the end of the first connecting rod 662 away from the L-shaped rod 661. The L-shaped rod 661 serves as the starting point for connecting the circular rod 62 and the first connecting rod 662, and there are two of them, which are respectively fixedly installed on the two side ends of the circular rod 62. This layout ensures that the rotation of the circular rod 62 can be evenly transmitted to the connecting rod systems on both sides. Then, one end of the first connecting rod 662 is sleeved outside the L-shaped rod 661 to achieve a rotatable connection. The quantity and distribution position of the first connecting rod 662 are adapted to the L-shaped rod 661, which means that there is one first connecting rod 662 on each side connected to the corresponding L-shaped rod 661 to ensure the balance and stability of the transmission. Finally, the second connecting rod 664 serves as a bridge connecting the first connecting rod 662 and the connecting rod 663. One end of it is sleeved outside the connecting rod 663 and is rotatably connected through a pin shaft. The other end of the second connecting rod 664 is hinged to the end of the first connecting rod 662 away from the L-shaped rod 661. This hinged manner allows the two to rotate relative to each other at the connection point, so as to adapt to the swinging trajectory of the first connecting rod 662 when the circular rod 62 rotates. When the circular rod 62 rotates under the drive of external power, the L-shaped rod 661 rotates accordingly and drives the first connecting rod 662 to swing. Since the two ends of the second connecting rod 664 are respectively hinged to the first connecting rod 662 and the connecting rod 663, the swing of the first connecting rod 662 will be converted into the swing of the second connecting rod 664, and further through the transmission of the connecting rod 663, the up and down movement of the piston 65 in the inflating cylinder 64 is realized. In this way, as the circular rod 62 continues to rotate, the piston 65 will continuously perform up and down reciprocating motions, thereby completing the inflation process.

[0074] In a preferred embodiment of the present utility model, it can be further configured as: as Figure 1 、 Figure 3 shown; the air storage assembly 7 includes:

[0075] An air tank 71, fixedly installed outside the flocculation sedimentation tank 1, and an intake main pipe 72 is communicated with the air tank 71;

[0076] Branch pipes 73, there are two of them, one end of which is communicated with the intake main pipe 72, and the other end of which is communicated with the inflating cylinder 64; and

[0077] The air outlet hose 74, one end of which is in communication with the gas tank 71. The gas storage assembly 7 is mainly composed of a gas tank 71, an intake main pipe 72, two branch pipes 73 and an air outlet hose 74. The gas tank 71, as the core storage component of the whole system, is fixedly installed outside the flocculation sedimentation tank 1. This not only ensures the stability of the gas tank but also facilitates maintenance and repair. An intake main pipe 72 is connected to the gas tank 71, and this main pipe is responsible for transporting the gas generated by an external gas source into the gas tank 71 for storage. The high-pressure gas generated in the inflator 64 is filled into the gas tank 71 through the two branch pipes 73. In addition, the gas storage assembly 7 is also equipped with an air outlet hose 74, one end of which is in communication with the gas tank 71, and the gas in the gas tank 71 can be released through the air outlet hose 74.

[0078] In a preferred embodiment of the present invention, it can be further configured as follows: As Figure 1 、 Figure 5 shown; An intake valve 9 is provided on the inflator 64, exhaust valves 10 are provided on both of the two branch pipes 73, a pressure gauge 11 and a pressure relief valve 13 are also provided on the surface of the gas tank 71, and an air outlet valve 12 is provided on the air outlet hose 74. The inflator 64, as a key component for gas distribution, is provided with an intake valve 9, and this intake valve 9 is responsible for opening at an appropriate time to allow external air or the gas to be compressed to be inhaled into the inflator 64. At the same time, the two branch pipes 73, as a bridge connecting the gas storage assembly 7 and the inflator 64, are both provided with exhaust valves 10. The function of the exhaust valve 10 is that when the gas pressure in the inflator 64 reaches or exceeds the pressure in the gas tank 71, the exhaust valve 10 opens. At this time, when the piston 65 moves upward, the outside air can only enter the inner side of the inflator 64 through the exhaust valve 10. Due to the existence of the exhaust valve 10, the gas in the gas tank 71 will not flow back into the inflator 64. On the contrary, when the piston 65 moves downward, the gas in the inflator 64 can only enter the gas tank 71 through the exhaust valve 10 and will not be discharged outside the inflator 64 through the intake valve 9. The high-pressure gas is discharged into the gas tank 71. In order to further monitor and adjust the operating state of the whole system, a pressure gauge 11 and a pressure relief valve 13 are also provided on the surface of the gas tank 71. The pressure gauge 11 can display the pressure situation inside the gas tank in real time, providing intuitive data support for the operator so as to timely adjust the gas supply or conduct safety maintenance. In addition, the air outlet hose 74, as the output pipe of the gas tank 71, is provided with an air outlet valve 12. The main function of the air outlet valve 12 is to automatically reduce the gas pressure below the set value when the gas is discharged through the air outlet hose 74 to prevent damage to the system or external equipment due to excessive pressure. This design not only improves the safety of the system but also increases its application flexibility.

[0079] In a preferred embodiment of the present invention, it can be further configured as follows: As Figure 1 、 Figure 6As shown; the cleaning assembly 8 includes:

[0080] A frame 81, which is arranged on the flocculation sedimentation tank 1 and can reciprocate above the flocculation sedimentation tank 1;

[0081] A blowpipe 82, which is fixedly installed on one side surface of the frame 81 close to the flocculation sedimentation tank 1; and

[0082] Air outlet nozzles 83, several of which are arranged at equal intervals on the blowpipe 82, and their air outlet ends face one side of the ABS corrugated flocculation sedimentation device 3. The cleaning assembly 8 is mainly composed of the frame 81, the blowpipe 82 and several air outlet nozzles 83. The frame 81 serves as the support and moving platform for the entire cleaning assembly, is arranged above the flocculation sedimentation tank 1, and has the ability to reciprocate above the tank body. This design enables the cleaning assembly 8 to cover and clean the ABS corrugated flocculation sedimentation device 3. The blowpipe 82 is fixedly installed on one side surface of the frame 81 close to the flocculation sedimentation tank 1 and serves as the gas transmission channel. When the cleaning assembly 8 starts to work, an external air source transports gas into the blowpipe 82 through the air outlet hose 74 to provide power for subsequent cleaning operations. The air outlet nozzles 83 serve as the execution components of the cleaning operations. The number of them is set to several and they are arranged at equal intervals on the blowpipe 82. This layout ensures that the gas can be evenly and comprehensively sprayed onto the surface of the ABS corrugated flocculation sedimentation device 3, thereby achieving the best cleaning effect. The air outlet ends of the air outlet nozzles 83 face one side of the ABS corrugated flocculation sedimentation device 3 and can effectively remove impurities and sediments attached to the surface of the device. Among them, the air outlet nozzles 83 are integrally inclined, and the inclination angle is the same as the inclination angle of the corrugated plate of the ABS corrugated flocculation sedimentation device. A corresponding driving device can also be installed on the frame 81 to enable the frame 81 to move along the upper surface of the flocculation sedimentation tank 1, thus eliminating the need for manual pushing.

[0083] In a preferred embodiment of the present invention, it can be further configured as: such as Figure 1 、 Figure 6As shown in the figure; a slide rail is fixedly installed on the upper surface of the flocculation sedimentation tank 1, and a sliding member adapted to the slide rail is fixedly installed on the frame 81. The frame 81 can reciprocate above the flocculation sedimentation tank 1 through the slide rail and the sliding member. The flocculation sedimentation tank 1, as the core part of the entire water treatment system, has been carefully designed with slide rails on its upper surface. These slide rails are not only strong and durable but also have excellent guiding performance, providing a stable and reliable path for the reciprocating movement of the frame 81. At the same time, sliding members adapted to the slide rail are fixedly installed on the frame 81 of the cleaning assembly 8. These sliding members have been precisely processed and strictly tested to ensure their tight fit and smooth sliding with the slide rail. When the cleaning operation starts, the frame 81 and the sliding members thereon are manually pushed to reciprocate along the slide rail. During this process, the frame 81, as the main support structure of the cleaning assembly, not only bears key components such as the air blowing pipe 82 and the air outlet nozzle 83 but also realizes precise positioning and flexible movement above the flocculation sedimentation tank 1 through the interaction between the sliding members and the slide rail. This design enables the cleaning assembly 8 to easily cover and clean the clogging layer on the corrugated plate surface of the ABS corrugated flocculation sedimentation device as needed.

[0084] The specific working principle of a flocculation sedimentation device for sewage treatment in the present utility model is as follows:

[0085] Sewage enters the mixing area of the flocculation sedimentation tank 1 through the water inlet pipe 2. At this time, the inlet valve is in the open state. As the sewage flows in, the driving impeller 5 fixedly installed outside the rotating rod 4 is driven by the water flow, and then drives the rotating rod 4 to axially rotate on the flocculation sedimentation tank 1. This rotation process is synchronously transmitted to the round rod 62 through the interaction of the connecting plate 631, the first gear 632, and the second gear 633 in the driving assembly 63;

[0086] The rotation of the round rod 62 is converted into the vertical displacement of the piston 65 inside the air charging cylinder 64 through the connecting rod assembly 66. Specifically, the L-shaped rod 661 rotates with the round rod 62, drives the first connecting rod 662 to move, and then through the hinge action of the second connecting rod 664 and the connecting rod 663, pushes or pulls the piston 65 to move up and down inside the air charging cylinder 64. During this process, when the piston 65 moves upward, air is inhaled from the outside through the suction valve 9; when the piston 65 moves downward, the compressed air is pushed into the air tank 71 of the air storage assembly 7. The flow direction of the gas is controlled by the exhaust valve 10 on the branch pipe 73 to ensure that the high-pressure gas is safely stored in the air tank 71 for subsequent use in cleaning the corrugated plates on the surface of the ABS corrugated flocculation sedimentation device 3. At the same time, in cooperation with the use of the pressure relief valve 13, the pressure relief valve 13 can automatically open and close according to the working pressure of the system, so as to keep the internal pressure of the air tank 71 within the set safe range. When the internal pressure of the air tank 71 exceeds the preset value, the pressure relief valve 13 will automatically open to release some gas to relieve the pressure and prevent dangerous situations that may be caused by continuous pressure increase;

[0087] As the sewage treatment process progresses, a clogging layer may accumulate on the surface of the ABS corrugated flocculation sedimentation device 3, affecting the water flow channel. At this time, the connection valve between the mixing zone and the sedimentation zone is closed, and the sewage will not enter the sedimentation area. Moreover, the water in the sedimentation tank is discharged through the water outlet on the flocculation sedimentation tank 1. At this time, the ABS corrugated flocculation sedimentation device 3 will be exposed.

[0088] At this time, the air outlet valve 12 is opened, and the high-pressure gas in the gas tank 71 enters the air blowing pipe 82 through the air outlet hose 74. Manually push the frame 81 to move. The frame 81 reciprocally moves on the slide rail above the flocculation sedimentation tank 1 through the sliding members installed thereon, driving the air blowing pipe 82 and the equally spaced air outlet nozzles 83 thereon to blow the corrugated plates on the surface of the ABS corrugated flocculation sedimentation device 3, thereby blowing the corrugated plate surface, blowing away the accumulated suspended solids and impurities from the surface, and keeping the water flow channel unobstructed.

[0089] During the whole process, the pressure gauge 11 on the gas tank 71 monitors the internal pressure in real time to ensure the safe operation of the system. At the same time, the water inlet valve of the water inlet pipe 2 can adjust the water inflow according to needs.
