Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to a pressure-equalizing and flow-stabilizing water distribution device. Background Art

[0002] Water distribution involves distributing water across a specific work area according to a specific pattern. The most common method is to distribute water evenly across the work surface. The device that accomplishes this task is called a water distributor. Some water treatment projects utilize filter tanks, each containing a specially designed arrangement of filter media. A water distributor operates above the filter tank, evenly and steadily distributing the wastewater to each area of the filter tank to ensure consistent filtration.

[0003] In actual applications, multiple diversion pipes are often configured on the same branch pipe, and an outlet hole or nozzle structure is set at the bottom of the diversion pipe. However, since the distance between each diversion pipe and the water inlet end of the branch pipe is different, the pressure of the sewage reaching each diversion pipe is different. The diversion pipe closer to the water inlet end of the branch pipe often has a larger sewage output. This leads to uneven distribution of water distribution area, which in turn leads to differences in the workload of the filter material in each area of the filter tank. If the workload of the filter material is overloaded, its filtering effect will be reduced. In this regard, some solutions will use a specific nozzle structure to increase the water distribution area when sewage is output to improve the uniformity of water distribution. For example, Chinese patent CN104058502B discloses a pressure-equalizing turbulent flow water distributor to solve the technical problems of uneven water distribution and limited water distribution area of the medium filter water distributor in the prior art. A water distribution interface and a water distribution tray, the water inlet of the water distribution interface is connected to the water outlet of the water inlet pressure pump of the water distributor, and also includes a water equalization chamber, the water inlet of the water equalization chamber is connected to the water outlet of the water distribution interface, the water distribution tray is fixedly installed on the top surface of the water equalization chamber; at least 3 water diversion holes are arranged on the top surface of the water equalization chamber around the water distribution tray; water diversion thorns are arranged on the side wall of the water distribution tray, and the water diversion thorns are spirally arranged around the water distribution tray.

[0004] However, the above technical solution is only to set up multiple water distribution holes, set up water distribution thorns, and let the water distribution thorns spirally surround the water distribution plate. This structure cannot effectively overcome the problem that the outflow water pressure is small and the water distribution area formed after the nozzle structure in the above technical solution is small. Therefore, how to adjust the internal flow of each diversion pipe, balance the water output of different water distribution points, and achieve uniform and steady flow is one of the technical problems that urgently need to be solved in the industry. Summary of the Invention

[0005] The present invention provides a pressure-equalizing and flow-stabilizing water distribution device, which is helpful in solving the problem of uneven flow and outflow in each shunt pipe caused by the different positions of the shunt pipes from the water inlet ends of the branch pipes in some existing water distribution devices.

The diversion pipe includes a horizontally arranged horizontal pipe, the input end of the horizontal pipe is connected to the inside of the branch pipe, the output end of the horizontal pipe is connected to an elbow, the output end of the elbow is vertically downward and connected to a tapered pipe with a narrow upper end and a wide lower end, and the bottom of the tapered pipe is connected to a vertical pipe; a horizontally convex and annular boss is provided on the inner side wall of the vertical pipe, and the top of the boss is movably connected to a horizontally arranged stabilizing The pressure plate and the radial outer edge of the pressure stabilizing plate are fitted with the inner wall of the vertical tube, and the bottom of the radial outer edge of the pressure stabilizing plate is clamped on the top of the boss through an elastic part. The elastic expansion and contraction direction of the elastic part is in the vertical direction. The pressure stabilizing plate is provided with a through-hole structure with a longitudinal through-hole structure; a diverter plate is arranged at intervals below the pressure stabilizing plate on the inner side of the vertical tube, and the diverter plate is provided with a number of diverter holes with a longitudinal through-hole structure. A number of sputtering tables are connected below the diverter plate. The sputtering table is a trumpet-shaped structure with an "eight"-shaped longitudinal section. The top of the sputtering table is a sputtering curved surface located below the diverter hole.

[0008] Based on the above technical solution, a guide tube is concentrically arranged inside the transverse tube. The axial ends of the guide tube are open structures. The outer wall of the guide tube is fitted with the inner wall of the transverse tube, and spiral blades are arranged on the inner wall of the guide tube.

[0009] On the basis of the above technical solution, a raised end portion that bulges upward is provided at the center of the top surface of the voltage stabilizing plate, and the through-hole is located in a low-position area outside the raised end portion.

[0010] On the basis of the above technical solution, the diversion plate is a horizontal disc structure concentrically arranged inside the vertical pipe. The radial periphery of the disc structure is connected and fixed to the inner wall of the vertical pipe through a number of evenly distributed ribs. The gaps between adjacent ribs constitute a first diversion hole, and a number of evenly distributed second diversion holes are provided on the disc; a first sputtering table and a second sputtering table are longitudinally spaced apart and provided below the diversion plate. The sputtering surface of the first sputtering table is correspondingly arranged below the first diversion hole, and the sputtering surface of the second sputtering table is correspondingly arranged below the second diversion hole. The sewage passing through the first diversion hole and the second diversion hole will flow along the sputtering surfaces of the first sputtering table and the second sputtering table respectively to form an outward-expanding sputtering waterfall.

[0011] On the basis of the above technical solution, a plurality of ribs are provided on the top of the first sputtering table, the bottom of the ribs are connected to the sputtering curved surface of the first sputtering table, and the top of the ribs is connected to the bottom of the ribs.

[0012] On the basis of the above technical solution, the top of the second sputtering table is connected to the center position of the bottom of the diverter plate through a connecting column.

[0013] On the basis of the above technical solution, the elastic member is made of elastic material, and the elastic member includes an outer frame with a longitudinal cross-sectional profile of a rectangular structure, and a shock-absorbing cavity is provided inside the outer frame.

[0014] On the basis of the above technical solution, a plurality of support plates are provided in the shock-absorbing cavity. The support plates are annular vertical plate structures. The upper and lower ends of the support plates are respectively connected and fixed to the upper and lower sides of the outer frame, and adjacent support plates are distributed at intervals.

[0015] On the basis of the above technical solution, the bottom of the support piece is connected to a supporting seat with an annular structure, and the top of the supporting seat is spaced apart from the top of the outer frame.

[0016] On the basis of the above technical solution, a pleated sheet is provided in the shock-absorbing cavity. The pleated sheet is a ring-shaped pleated structure. There are several longitudinally distributed softening cavities inside the pleated sheet. The transverse width of the softening cavity alternates between large and small in the longitudinal direction. The upper and lower ends of the sheet are respectively connected to the upper and lower sides of the outer frame.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] 1. The pressure-equalizing and flow-stabilizing water distribution device of the present invention can automatically adjust the flow rate according to the sewage pressure at each diversion pipe through the cooperation of the pressure-stabilizing plate and the elastic part. When the pressure at a certain diversion pipe is relatively high, the pressure-stabilizing plate moves downward and squeezes the elastic part. Due to its own characteristics, the elastic part will provide an upward reverse force to the pressure-stabilizing plate. This cooperation method makes different water pressures subject to different degrees of resistance, forming an automatic water pressure adjustment structure. This automatic adjustment mechanism can effectively overcome the difference in outflow water pressure caused by the different positions of the diversion pipe from the water inlet end of the branch pipe, so that the internal flow and outflow of each diversion pipe tend to be balanced, thereby improving the uniformity of water distribution.

[0019] 2. Through the design of the diverter plate and the splashing table, the sewage will form an outward-expanding splashing waterfall when flowing out of the vertical pipe, which greatly increases the water distribution area, allowing the sewage to be more widely input into the filter tank, avoiding the problem of excessive concentration of the water distribution area, and further improving the uniformity of water distribution.

[0020] 3. When water flows from the branch pipe to the diversion pipe, the direction of the water flow changes after passing through the elbow. At the same time, the water flow on both sides of the elbow is prone to imbalance. The water flow velocity on the outside of the elbow is higher, and the water flow velocity on the inside of the elbow is lower, which makes the water flow turbulent. By setting a tapered tube with a narrow top and gradually wide bottom structure at the bottom of the elbow, according to the wall effect of the fluid and the principles of fluid mechanics, the water flow out of the elbow will flow along the tapered tube. The tapered tube can not only reduce the flow resistance, but also restore the water flow to uniformity, reduce the impact and imbalance on the pressure stabilizing plate, and improve the pressure equalization and flow stabilization effect. Finally, the diversion through the diversion plate further makes the water flow more evenly distributed in the output area of the diversion pipe, which can effectively improve the water distribution uniformity of the water distributor and ensure the water distribution effect.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0036] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1: Combination Figure 1-10As shown, this embodiment discloses a pressure-equalizing and flow-stabilizing water distribution device, which aims to solve the problem of uneven flow and outflow within each branch pipe 2 caused by the different positions of the branch pipes 2 from the water inlet end 11 of the branch pipe 1 in some existing water distribution devices. Through innovative structural design, each branch pipe 2 can automatically adjust its internal flow when facing different inlet pressures, thereby achieving uniform water distribution and flow stabilization, thereby improving the overall performance of the sewage treatment system.

[0040] Specifically, the pressure-equalizing and flow-stabilizing water distribution device includes a branch pipe 1, one axial end of which is an open water inlet end 11 for receiving the sewage to be treated; the other axial end of the branch pipe 1 is a closed end 12, which is sealed by a plug to prevent sewage leakage. The branch pipe 1 is connected to several diversion pipes 2 along its axial direction. Figure 1 The figure shows a structure in which five diversion pipes 2 are connected to the left and right sides of a branch pipe 1, and adjacent diversion pipes 2 are distributed at intervals. The function of the diversion pipes 2 is to divert and directionalize the sewage in the branch pipe 1.

[0041] Combine Figure 2 and Figure 3 As shown, the diversion pipe 2 comprises a horizontally arranged horizontal pipe 21. The input end of horizontal pipe 21 communicates with the interior of branch pipe 1, ensuring that sewage can flow smoothly from branch pipe 1 into diversion pipe 2. The output end of horizontal pipe 21 is connected to an elbow 22. The output end of elbow 22 is vertically downward and connected to a tapered pipe 23 that is narrow at the top and wide at the bottom. This design helps guide the flow of sewage and gradually increases the water flow area. The bottom of tapered pipe 23 is connected to a vertical pipe 24, which serves as the final output channel for sewage in the water distribution system.

[0042] Further, combined Figure 5 、 Figure 6 and Figure 8 The inner wall of the vertical tube 24 is provided with a horizontal, inwardly convex, annular boss 241. Boss 241 is welded to the inner wall of the vertical tube 24. It should be noted that the top of boss 241 is a horizontal end surface structure. A horizontally arranged voltage stabilizing plate 3 is movably connected to the top of boss 241. The radial outer edge of voltage stabilizing plate 3 abuts against the inner wall of the vertical tube 24, forming a retaining structure. This ensures high stability when voltage stabilizing plate 3 slides up and down, preventing it from easily tilting or shifting. A "T"-shaped latching edge 31 is provided on the radial outer edge of voltage stabilizing plate 3. The bottom of latching edge 31 is latched to the top of boss 241 via an elastic member 5. In this embodiment, elastic member 5 is made of rubber and its elastic expansion direction is vertical. It should be noted that the elastic expansion direction here refers to the vertical direction that plays the primary role in operation. This is a clever design based on its own material properties and physical structure, and does not mean that it lacks elastic expansion function in other directions.

[0043] like Figure 9 and Figure 10As shown, it should be noted that the cross-sectional structure shown in the figure only shows one side of the elastic member 5. In reality, the overall outline of the elastic member 5 is a circular ring structure. In this embodiment, the elastic member 5 includes an outer frame 51 with a rectangular longitudinal cross-sectional outline. The outer frame 51 has a shock-absorbing cavity 53 disposed therein. The shock-absorbing cavity 53 is provided with two support plates 52 spaced laterally inward and outward. The support plates 52 are annular vertical plates with their upper and lower ends connected and fixed to the upper and lower sides of the outer frame 51, respectively, and adjacent support plates 52 are spaced apart. During operation, when subjected to the downward pressure of the upper pressure stabilizing plate 3, the outer frame 51 and the support sheet 52 share the downward pressure and conduct it longitudinally. Due to the existence of the shock absorbing cavity 53 and the flexibility of the support sheet 52 itself, the downward pressure is converted into partial deformation, achieving a shock absorbing effect. Moreover, since the elastic member 5 has the elastic property of being reset under pressure, it will generate an upward reverse force on the upper pressure stabilizing plate 3. This reverse force is inversely proportional to the downward pressure and corresponds to the pressure of the water flow on the pressure stabilizing plate 3, thus forming an automatic water pressure adjustment structure. This automatic adjustment mechanism can effectively overcome the difference in outflow water pressure caused by the different positions of the diversion pipe 2 from the water inlet end 11 of the branch pipe 1, so that the internal flow and outflow of each diversion pipe 2 tend to be balanced, thereby improving the uniformity of water distribution.

[0044] The pressure stabilizing plate 3 is provided with a longitudinal through-hole structure 33 for sewage to pass through. Figure 6 As shown, the perforation 33 is a circular arc strip through-hole structure with a transverse inner and outer layered structure. A raised end portion 32 that bulges upward is provided at the center of the top surface of the pressure stabilizing plate 3, and the perforation 33 is located in a low-position area outside the raised end portion 32. This design helps the sewage to form a certain water flow distribution on the pressure stabilizing plate 3, and can divert and guide the water flow to diffuse uniformly in all directions, so that the sewage flows more evenly through the perforation 33 into the lower part of the vertical pipe 24. Moreover, since the distribution position of the perforation 33 is closer to the radial outer edge of the pressure stabilizing plate 3, the force position of the downward pressure generated by the water flow on the pressure stabilizing plate 3 is closer to the top of the elastic member 5, which is conducive to the rapid transmission of force.

[0045] In this embodiment, the boss 241 only constitutes a single-sided limiting structure below the voltage stabilizing plate 3. In other embodiments, another boss 241 can be set above the voltage stabilizing plate 3 to constitute a double-sided limiting structure to further constrain and control the up and down movable stroke of the voltage stabilizing plate 3.

[0046] Combine Figure 2 、 Figure 5 、 Figure 6 and Figure 7Inside the vertical pipe 24, below the voltage stabilizing plate 3, a diverter plate 25 is spaced apart. This diverter plate 25 is provided with a number of longitudinal through-hole diverter holes. Connected below the diverter plate 25 are several sputtering platforms. The sputtering platforms are trumpet-shaped structures with an "eight"-shaped longitudinal cross-section. The tops of the sputtering platforms are curved sputtering surfaces located below the diverter holes. After the sewage passes through the diverter holes, it impacts the sputtering surfaces of the sputtering platforms, forming an outward-expanding sputtering waterfall. This further increases the water distribution area and ensures more uniform water distribution.

[0047] Specifically, the diverter plate 25 is a horizontal disc structure concentrically arranged inside the vertical pipe 24. The radial periphery of the disc structure is connected and fixed to the inner wall of the vertical pipe 24 by 6 ribs 253 that are symmetrically and evenly distributed on the center. The gaps between adjacent ribs 253 constitute a first diverter hole 251, and a number of evenly distributed second diverter holes 252 are provided on the disc; a first sputtering table 26 and a second sputtering table 27 are longitudinally spaced and distributed below the diverter plate 25. The sputtering surface of the first sputtering table 26 is correspondingly arranged below the first diverter hole 251, and the sputtering surface of the second sputtering table 27 is correspondingly arranged below the second diverter hole 252. Since the top of the first sputtering table 26 is connected to the bottom of the diverter plate 25 to form a horizontal internal and external partition structure, the sewage passing through the first diverter hole 251 and the second diverter hole 252 will flow along the sputtering surfaces of the first sputtering table 26 and the second sputtering table 27 respectively to form an outward-expanding sputtering waterfall, further expanding the water distribution area and improving the uniformity of the water distribution. It should be noted that, in this embodiment, the curvature of the sputtering surface of the second sputtering table 27 is smaller than the curvature of the sputtering surface of the first sputtering table 26, and the length of the sputtering surface of the second sputtering table 27 is greater than the length of the sputtering surface of the first sputtering table 26, forming an overall stacked structure that is narrow at the top and wide at the bottom. This is conducive to the formation of a double-layer outward expansion surface of the sewage after sputtering, and cooperates with the diversion effect of the diversion plate 25 to split and output the sewage in the same diversion pipe 2, further improving the uniformity and stability of water distribution.

[0048] In order to enhance the stability of the first sputtering table 26, six ribs 261 are provided on the top of the first sputtering table 26. The ribs 261 are vertical plate structures. The bottom of the ribs 261 is connected to the sputtering surface of the first sputtering table 26, and the top of the ribs 261 is connected to the bottom of the ribs 253. This connection method not only ensures the stability of the sputtering table, but also forms a partition structure on the sputtering surface of the first sputtering table 26, effectively performing a zoning design, facilitating the dispersed flow and sputtering of sewage in all directions, and reducing the impact of uneven sputtering direction caused by structural assembly angle deviation.

[0049] Furthermore, the top of the second sputtering table 27 is connected to the center position of the bottom of the diverter plate 25 through a connecting column 271. This connection method further ensures the overall structural stability of the sputtering table and ensures the spacing between the two sputtering tables. At the same time, different lengths of connecting columns 271 can be selected according to actual operational requirements to adjust the spacing between the sputtering tables and achieve different sputtering coverage specifications.

[0050] In addition, combined Figure 2 and Figure 4 As shown, in this embodiment, a guide tube 4 is concentrically disposed within the transverse tube 21. The guide tube 4 has open ends at both axial ends, and its outer wall is aligned with the inner wall of the transverse tube 21. Spiral blades 41 are disposed on the inner wall of the guide tube 4. When sewage flows from the branch pipe 1 into the transverse tube 21, the spiral blades 41 guide the sewage, causing it to form a spiral flow within the transverse tube 21. This helps utilize vortexes to create a centripetal convergence effect, increasing the water flow velocity. This allows the sewage to flow more smoothly and stably from the branch pipe 1 into the diversion pipe 2, facilitating a more uniform entry of the sewage into each diversion pipe 2. This also helps to reduce the imbalance of the water flow as it passes through the rear elbow 22.

[0051] The inner cavity of the branch pipe 1 is defined as the water inlet cavity a, the inner cavity of the horizontal pipe 21 is the diversion cavity b, the inner cavity of the elbow 22 is the guide cavity c, the inner cavity of the tapered pipe 23 is the slow flow cavity d, and the inner cavity of the vertical pipe 24 is the homogenization cavity e. During the specific implementation process, the sewage enters the water inlet chamber a from the input end of the branch pipe 1, and gradually differentiates and flows into the diversion chamber b. In the diversion chamber b, it is affected by the diversion of the guide tube 4 to form a vortex, and then passes through the guide chamber c and enters the slow flow chamber d. The sewage in the slow flow chamber d is homogenized for the first time and steadily descends through the perforation 33 of the pressure stabilizing plate 3 to enter the homogenization chamber e. In this process, the downward pressure generated on the pressure stabilizing plate 3 according to the size of the water flow will be reflected in the extrusion force of the pressure stabilizing plate 3 on the elastic part 5. The elastic part 5 will generate a corresponding reverse force according to the size of the pressure intensity, and the pressure stabilizing plate 3 applies an upward thrust, which will form a resistance to the water flow to achieve automatic adjustment of the water pressure and the equalization and stabilization effect of the diversion pipes 2 at different positions. The sewage entering the homogenization chamber e then passes through the first diversion hole 251 and the second diversion hole 252, and forms a sputtering waterfall along the first sputtering table 26 and the second sputtering table 27 respectively, and is output with a larger water distribution surface. The pressure-equalizing and flow-stabilizing water distribution device of the present invention effectively solves the problem of flow imbalance caused by the position difference of the diversion pipe 2 in the existing water distribution device through the innovative structural design of the voltage stabilizing plate 3, elastic member 5, diversion plate 25 and sputtering table. This device not only realizes the balanced regulation of the internal flow of each diversion pipe 2, but also significantly improves the water distribution uniformity and sewage treatment effect by expanding the water distribution area and improving the water flow stability. Compared with the existing technology, the present invention has the advantages of innovative flow regulation mechanism, significantly improved water distribution uniformity, enhanced system stability and a wide range of applications, and has broad market application prospects and promotion value. In the future sewage treatment field, this device is expected to become one of the important equipment for improving sewage treatment efficiency and quality.

[0052] Example 2: Based on Example 1, Figure 11 As shown, in this embodiment, the bottom of the support sheet 52 is connected to a ring-shaped support seat 54. The support seat 54 has a "T"-shaped structure, with its top crossbeam connected to the inner wall of the outer frame 51 and the outer wall of the support sheet 52, respectively. The top of the support seat 54 is spaced apart from the top of the outer frame 51. This structure allows the elastic member 5 to be layered. When subjected to a small compressive force, the support sheet 52 and the outer frame 51 independently transmit force. When subjected to a larger compressive force, the deformation of the support sheet 52 and the outer frame 51 reaches a threshold, and the support seat joins and participates in the force transmission, resulting in a hierarchical effect in the pressure response of the elastic member 5. This helps to diversify the working modes of the elastic member 5. The support seat 54 also provides additional support for the support sheet 52, preventing deformation of the support sheet 52 under greater pressure, thereby extending the service life of the elastic member 5.

[0053] Example 3: Based on Example 1, Figure 12As shown, in this embodiment, a pleated sheet 55 is disposed within the shock-absorbing chamber 53. The pleated sheet 55 has an annular pleated structure and contains a plurality of longitudinally distributed softening chambers 56. The transverse widths of the softening chambers 56 alternate between large and small in the longitudinal direction. The upper and lower ends of the sheet are respectively connected to the upper and lower sides of the outer frame 51. The design of the pleated sheet 55 further enhances the shock-absorbing effect of the elastic member 5, allowing the pressure stabilizing plate 3 to move up and down more smoothly when subjected to changes in sewage pressure, thereby improving the accuracy of flow regulation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
