Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a wastewater discharge device for water conservancy projects. Background Technology

[0002] In fields such as water conservancy projects, municipal drainage, and industrial production, wastewater discharge is a crucial link in ensuring production operations and environmental safety. Therefore, wastewater discharge is an indispensable process. The discharged wastewater often contains a large amount of suspended solids, especially fine metal particles. If these pollutants are discharged directly without effective treatment, they will cause serious harm to the aquatic ecological environment and human health. At present, common wastewater discharge devices usually use simple pipeline transportation or are equipped with basic filtration and separation equipment. However, existing discharge devices mostly rely on static filter screens or single centrifugal separators. When wastewater is directly pumped into the separation equipment through pipelines, the wastewater flow rate is too fast, which will impact the inside of the separation cylinder. This will significantly shorten the effective contact time between the separation cylinder and the wastewater separation medium. In particular, fine metal particles, due to their light weight and low inertia, are very easy to penetrate the filter barrier or be carried away by the wastewater and discharged directly, affecting the stability of wastewater discharge and continuous treatment efficiency. Summary of the Invention

[0007] The drain pipe is equipped with a sewage flow component that drives the separation cylinder to rotate and pushes the sewage out of the discharge chamber.

[0008] The discharge chamber and the diversion box are connected by a turbulence-inducing component that ensures full contact between the sewage and the separation cylinder.

[0009] Preferably, the turbulence assembly includes a first pulley and a second pulley rotatably connected to the outside of the splitter box, and two concentric shafts mounted on one side of two cranks. The first pulley and the second pulley are used to drive the two concentric shafts to rotate. A synchronous belt is sleeved between the first pulley and the second pulley. A first servo motor is fixedly connected to the outside of the splitter box, and the first servo motor is used to drive the first pulley to rotate.

[0010] Preferably, the sewage flow assembly includes an installation box fixedly connected inside the drain pipe and a rotating column installed at one end of the separation cylinder. One end of the rotating column extends into the interior of the installation box and is fixedly connected to a first gear. A second servo motor is fixedly connected inside the installation box and is used to drive the first gear to rotate. Several inclined auxiliary push rods are installed on the outside of the separation cylinder.

[0011] Preferably, a connecting cylinder is movably sleeved on the outside of the rotating column, and a connecting ring frame is fixedly connected to one end of the connecting cylinder. The connecting ring frame is sleeved on the outside of the rotating column. A cleaning rod is installed at the bottom end of the auxiliary push rod and on the outside of the connecting ring frame. The cleaning rod maintains forward and reverse rotation between itself and the separation cylinder through the connecting ring frame.

[0012] Preferably, the end of the connecting cylinder column away from the connecting ring frame passes through the mounting box and is fixedly connected to the second gear, and the second gear is sleeved on the outside of the rotating column. The inside of the mounting box is rotatably connected to an auxiliary gear that meshes with the first gear and the second gear.

[0013] Preferably, the turbulence component includes a diversion tube fixedly connected between the discharge chamber and the diversion box, and the diversion tube communicates with the interior of the diversion box and the discharge chamber. Several drainage blades are rotatably connected inside the diversion tube, and the drainage blades are configured as curved willow leaf-shaped structures. The exterior of the drainage blades is provided with discharge holes for sewage to flow through.

[0014] Preferably, a concentric rod is fixedly connected inside the separation cylinder, and one end of the concentric rod extends into the interior of the drainage cylinder and is fixedly connected to several drainage blades. A stabilizing frame is fixedly connected inside the drainage cylinder, and the stabilizing frame is sleeved on the outside of the concentric rod.

The layered ring frame is a conical mesh ring structure.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. This invention, through the synergistic effect of the discharge component and the turbulence component, drives the circulation frame to complete multi-dimensional reciprocating motion in the up, down, left, and right directions inside the diversion box. On the one hand, it forms a barrier to slow down the flow rate of sewage, and on the other hand, it promotes the full mixing of sewage and reagents, so that fine metal particles can be efficiently aggregated into large flocs through the adsorption bridge effect, thereby improving the capture efficiency of metal particles during centrifugal separation in the separation cylinder, reducing metal particle residue, and ultimately improving the quality of sewage discharge.

[0018] 2. In this invention, the first servo motor drives the first pulley and the second pulley to rotate synchronously via belt transmission, thereby driving the concentric shaft and crank to move, ensuring that the crank and the circulation frame in the discharge assembly achieve periodic reciprocating motion, thus effectively disturbing the sewage and enhancing the mixing and slowing effect;

[0019] 3. In the wastewater flow assembly of the present invention, the cleaning rod moves in both directions with the separation cylinder through the connecting ring frame. During the rotation, it can scrape and clean the outside of the separation cylinder, which can effectively prevent impurities in the wastewater from adsorbing and clogging the mesh of the separation cylinder, ensuring the wastewater permeability of the separation cylinder and maintaining the long-term stable separation effect of the device.

[0020] 4. The present invention uses an auxiliary push rod that is inclined outside the separation cylinder to form a shearing action with the sewage by means of its own inclined surface, and at the same time actively pushes the sewage in the discharge chamber to flow towards the drain pipe, which significantly accelerates the sewage discharge speed and improves the sewage treatment capacity and treatment efficiency of the device.

[0021] 5. The present invention forms a smooth transition structure by setting an arc-shaped groove on the inner wall of the discharge chamber. The fluid flows evenly along the arc surface, reducing the scouring and erosion of the pipe wall, ensuring that sewage is smoothly introduced into the drain pipe, and maintaining the system's drainage efficiency.

[0022] 6. The present invention can form a barrier for the sewage in the diversion tube by using the layered ring frame (conical mesh ring structure) in the turbulence component, so as to avoid the stratification of sewage and metal particles, and ensure the stable flow path of sewage from the diversion box to the separation tube. At the same time, when the discharge blades (curved willow leaf shape with discharge holes) rotate, they can slow down the flow speed of sewage and prolong the contact time, ensuring effective contact between the separation tube and metal particles, improving the separation efficiency of the separation tube and the quality of sewage discharge.

[0023] 7. This invention guides edge sewage to the central area through a circular arc transition ring frame, and the stabilizing frame increases sewage turbulence, weakens the impact of sewage on the separation cylinder, ensures the stability of the separation process, and improves the separation efficiency of the separation cylinder and the quality of sewage discharge.

[0041] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] This invention provides, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The sewage discharge device for water conservancy projects shown includes a discharge chamber 1, a separation cylinder 14 and a drain pipe 12. A sewage discharger 13 is installed on the outside of the discharge chamber 1 to discharge the residue inside the separation cylinder 14. A diversion box 11 is installed at one end of the discharge chamber 1 to introduce sewage into its interior. A discharge component 2 for controlling the slow flow of sewage is provided between the diversion box 11 and the separation cylinder 14. The discharge component 2 promotes the adsorption of sewage with chemicals and bridges.

[0043] The emission assembly 2 includes two side frames 22 movably connected inside the diversion box 11 and an arc-shaped annular groove 26 opened inside the emission compartment 1. Several circulation frames 21 and two transverse columns 25 are connected between the two side frames 22. The circulation frames 21 are designed with a mountain-shaped structure. Two crank rods 23 that cooperate with the side frames 22 are movably connected inside the diversion box 11. Two limiting shaft columns 24 are connected between the two crank rods 23 and the side frames 22.

The circulation racks 21 and side racks 22 are distributed at different positions inside the diversion box 11, allowing them to contact the wastewater at different locations within the diversion box 11. Furthermore, the number of crank rods 23 matches the number of side racks 22; therefore, each side rack 22 has two crank rods 23 on one side. One set of side racks 22 and two crank rods 23 are connected to two concentric shaft columns 31. Additionally, the separation cylinder 14, discharge chamber 1, and drainer 13 are specifically... The structure and principle are existing technologies, so they are not described in detail in this application. Currently, in sewage discharge, the process of cleaning the impurities in the separation cylinder 14 after the sewage is discharged in stages is as follows: First, the separation cylinder 14 uses centrifugal force to separate the metal particles in the sewage. The connected metal particles are temporarily attached to the inner wall of the separation cylinder 14. Then, the outer door of the discharge chamber 1 is opened, and the cylinder door of the separation cylinder 14 near the sewage discharger 13 is opened to guide the impurities inside the separation cylinder 14 to the vicinity of the sewage discharger 13. Then, the sewage discharger 13 has a built-in solenoid valve or pneumatic gate to discharge the metal particles to the outside.

[0045] refer to Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, the outside of the splitter box 11 is provided with a turbulence assembly 3 that drives the crank 23 and the circulation frame 21 to move in multiple dimensions.

[0046] refer to Figure 2 , Figure 3 and Figure 7 As shown, the drain pipe 12 is equipped with a sewage flow assembly 4 that drives the separation cylinder 14 to rotate and pushes the sewage out of the discharge chamber 1. The sewage flow assembly 4 includes a mounting box 41 fixedly connected inside the drain pipe 12 and a rotating column 45 installed at one end of the separation cylinder 14. One end of the rotating column 45 extends into the interior of the mounting box 41 and is fixedly connected to a first gear 42. A second servo motor 46 is fixedly connected inside the mounting box 41 and is used to drive the first gear 42 to rotate. Several inclined auxiliary push rods 401 are installed on the outside of the separation cylinder 14.

[0047] refer to Figure 2 , Figure 3 and Figure 7 As shown, a connecting cylinder 47 is movably sleeved on the outside of the rotating column 45. One end of the connecting cylinder 47 is fixedly connected to a connecting ring frame 48, which is sleeved on the outside of the rotating column 45. The bottom end of the auxiliary push rod 401 and the outside of the connecting ring frame 48 are jointly installed with a cleaning rod 49, which maintains forward and reverse rotation with the separating cylinder 14 through the connecting ring frame 48. The end of the connecting cylinder 47 away from the connecting ring frame 48 passes through the mounting box 41 and is fixedly connected to a second gear 43, which is sleeved on the outside of the rotating column 45. An auxiliary gear 44 that meshes with the first gear 42 and the second gear 43 is rotatably connected inside the mounting box 41.

[0048] refer to Figure 2 , Figure 3 and Figure 7 As shown, there are three auxiliary push rods 401 arranged in a circular array around the outside of the separation cylinder 14. The number of cleaning rods 49 is equal to the number of auxiliary push rods 401, and the bottom of the cleaning rods 49 contacts the outside of the separation cylinder 14 for cleaning the outside of the separation cylinder 14.

[0049] refer to Figure 6 , Figure 7 and Figure 8 As shown, a turbulence assembly 5 is connected between the discharge chamber 1 and the diversion box 11 to ensure full contact between the sewage and the separation cylinder 14. The turbulence assembly 5 includes a diversion cylinder 51 fixedly connected between the discharge chamber 1 and the diversion box 11, and the diversion cylinder 51 communicates with the interior of the diversion box 11 and the discharge chamber 1. Several drainage blades 53 are rotatably connected inside the diversion cylinder 51, and the drainage blades 53 are configured as curved willow leaf-shaped structures.

[0050] refer to Figure 6 , Figure 7 and Figure 8 As shown, a concentric rod 52 is fixedly connected inside the separation cylinder 14, and one end of the concentric rod 52 extends into the interior of the diversion cylinder 51 and is fixedly connected to several diversion blades 53. A stabilizing frame 54 is fixedly connected inside the diversion cylinder 51, and the stabilizing frame 54 is sleeved on the outside of the concentric rod 52. An arc transition ring frame 57 is fixedly connected to the side of the diversion cylinder 51 near the discharge chamber 1 and the separation cylinder 14, and the arc transition ring frame 57 is a conical structure. A layered ring frame 55 is rotatably connected inside the diversion cylinder 51, and the layered ring frame 55 is fixedly sleeved on the outside of the concentric rod 52. The layered ring frame 55 is a conical mesh ring structure. The number of diversion blades 53 is set to three, and the three diversion blades 53 are arranged in an array around the outside of the concentric rod 52.

[0051] Working principle:

[0052] When using;

[0053] refer to Figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, when sewage needs to be discharged and fine metal particles separated, the first servo motor 35 drives the first pulley 32 to rotate synchronously. The first pulley 32 achieves transmission through meshing with the synchronous belt 34, which in turn drives the second pulley 33 to rotate synchronously. With the synchronous operation of the first pulley 32 and the second pulley 33, the two concentric shafts 31 rotate accordingly, and further drive the two cranks 23 to move along the internal circumferential direction of the discharge chamber 1. During the rotation of the cranks 23, they will disturb the sewage and impurities in the water at the inner edge of the diversion box 11, thereby enhancing the internal flow of the sewage.

[0054] refer to Figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, simultaneously, the rotation of the two cranks 23 drives the two limiting shafts 24 to rotate synchronously, thereby pushing one of the side frames 22 to move to the right along the inside of the splitter box 11. This side frame 22, in turn, moves synchronously with the other two cranks 23, causing the other side frame 22 to move accordingly. During its rightward movement, the side frame 22 gradually extends deeper into the splitter box 11, and then moves to the left along the inside of the splitter box 11 and returns to its original position, thus achieving a periodic reciprocating motion. This motion can drive the three circulating frames 21 to complete multi-dimensional reciprocating motions up, down, left, and right along the inside of the splitter box 11. On the one hand, the moving circulation frame 21 can form a barrier for the sewage in the diversion box 11, slowing down the flow speed of the sewage into the separation cylinder 14, ensuring that the separation cylinder 14 can fully contact the sewage, thus maintaining a stable state when separating impurities in the sewage; on the other hand, the multi-dimensional movement of the circulation frame 21 can promote the sewage and the agent to fully mix and contact in the diversion box 11. After the fine metal particles in the sewage react with the agent, they will aggregate into large flocs through the adsorption bridging effect of the agent, which will greatly improve the capture efficiency of metal particles in the separation cylinder 14 during centrifugal separation, and ultimately improve the quality of sewage discharge.

[0055] refer to Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, when the sewage in the diversion box 11 needs to be discharged into the separation cylinder 14, the diversion box 11 first slows down the sewage to reduce the impact when it enters the separation cylinder 14. After buffering, the sewage flows smoothly into the separation cylinder 14. Then, the second servo motor 46 starts and drives the rotating column 45 to rotate synchronously, which in turn drives the separation cylinder 14 to rotate synchronously along the inside of the discharge chamber 1. During the rotation, the separation cylinder 14 generates centrifugal force on the sewage inside, throwing the sewage out of the cylinder. The metal particles in the sewage are intercepted and retained by the separation cylinder 14. After the sewage is thrown out into the discharge chamber 1, the arc groove 26 on the inner wall of the discharge chamber 1 makes the two ends of the pipe form a smooth arc transition structure, which can effectively avoid local wear caused by sewage accumulation and ensure that the sewage can flow smoothly to the drain pipe 12 and finally be discharged.

[0056] refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, simultaneously, when the second servo motor 46 rotates, it also drives the first gear 42 to rotate synchronously. The first gear 42 achieves transmission through meshing with the auxiliary gear 44, causing the auxiliary gear 44 to drive the second gear 43 to rotate along the inside of the mounting box 41. The second gear 43 further drives the connecting cylinder column 47 to rotate along the outside of the rotating column 45, thereby driving the connecting ring frame 48 to rotate synchronously. Finally, the connecting ring frame 48 drives the cleaning rod 49 and the auxiliary push rod 401 to rotate along the outside of the separation cylinder 14. During this process, the cleaning rod 49 and the separation cylinder 14 move in opposite directions. When it rotates, it scrapes and cleans the outside of the separation cylinder 14, which can prevent impurities in the sewage from adsorbing and clogging the mesh of the separation cylinder 14, ensuring that the sewage passes through normally. The auxiliary push rod 401 forms a shearing action with the sewage by virtue of its own inclined surface, and at the same time pushes the sewage in the discharge chamber 1 to flow towards the drain pipe 12, thereby accelerating the sewage discharge speed.

[0057] refer to Figure 2 , Figure 6 and Figure 8 As shown, when sewage flows from the diversion box 11 to the separation cylinder 14 and the separation cylinder 14 separates and discharges the sewage, the layered ring frame 55 first forms a barrier for the sewage that is about to flow into the diversion cylinder 51, ensuring that the sewage and the metal particles therein are fully mixed and flowed, avoiding the situation of sewage and metal particles being separated. At the same time, the concentric rod 52 rotates synchronously with the rotation of the rotating column 45, thereby driving the drainage blade 53 to rotate synchronously along the inside of the diversion cylinder 51. The structural characteristics of the drainage blade 53 enable it to slow down the flow speed of the sewage on its surface when it comes into contact with the sewage, prolong the contact time, and ensure that the sewage and the drainage blade 53 fully interact.

[0058] refer to Figure 2 , Figure 6 and Figure 8As shown, the guide vanes 53 simultaneously perform preliminary separation of sewage and metal particles through the discharge holes 56 on their surface, ensuring that the metal particles remain dispersed when the sewage enters the separation cylinder 14, creating conditions for efficient separation in the separation cylinder 14 and thus improving the quality of sewage discharge. In addition, the arc transition ring 57 inside the guide cylinder 51 forms a smooth arc transition structure, which guides the sewage at the edge to the central area when it comes into contact with the sewage at the edge. When the sewage flows through the stabilizing frame 54, the horizontally flowing sewage interacts with the sewage in the central area, increasing the turbulence between the sewage and the metal particles. This process further weakens the impact of the sewage on the interior of the separation cylinder 14, ensuring that the separation cylinder 14 can maintain stable contact with the sewage and guaranteeing separation efficiency.

[0059] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
