Description

TECHNICAL FIELD

[0001] The present application relates to sewage treatment equipment technical field, in particular to a kind of pressure-equalizing steady flow water distribution device. BACKGROUND

[0002] “water distribution” is that water is arranged according to certain rules on certain working area, and the most common is that water is evenly distributed on working face.The device for completing this task is called water distributor.In some water treatment projects, filter tank is arranged, filter material is arranged in filter tank according to specific design, and sewage to be treated is evenly and stably input into each area of filter tank by water distributor above filter tank to ensure stable filtration effect.

[0003] In practical application, multiple branch pipes are often configured on the same branch pipe, and flow holes or nozzle structures are further arranged at the bottom of branch pipe, but due to the difference in distance between branch pipe and water inlet end of branch pipe, the pressure of sewage reaching each branch pipe is different, and the output of sewage of branch pipe closer to water inlet end of branch pipe is larger, which leads to uneven distribution of water distribution area, and further leads to the difference in work burden of filter material in each area of filter tank, and the filtration effect of filter material is reduced if the work burden of filter material is overloaded.For this problem, some schemes increase water distribution area when sewage is output by using specific nozzle structure to improve water distribution uniformity, for example, Chinese patent CN104058502B discloses a pressure-equalizing turbulent flow type water distributor to solve the technical problems of uneven water distribution and limited water distribution area of medium filter water distributor in prior art.The water inlet of water distribution interface is communicated with the water outlet of water inlet pressure pump of the water distributor, and the water inlet of water distribution interface is communicated with the water outlet of water distribution interface, and the top surface of water distribution interface is fixedly provided with water distribution disc;at least three water distribution holes are arranged around the water distribution disc on the top surface of water distribution interface;water distribution thorns are arranged on the side wall of water distribution disc, and the water distribution thorns are spirally arranged around the water distribution disc.

[0004] However, the above technical scheme only sets multiple water distribution holes, sets water distribution thorns, and makes water distribution thorns spirally arranged around water distribution disc, and this structure cannot effectively overcome the problem that the water distribution area formed after the water with small pressure passes through the nozzle structure in the above technical scheme is small, and therefore, how to adjust the internal flow of each branch pipe, balance the output of different water distribution points, and achieve uniform and steady flow is one of the technical problems urgently to be solved in the industry.

[0008] On the basis of the above technical scheme, a flow guide cylinder is arranged concentrically in the horizontal pipe, the axial ends of the flow guide cylinder are open, the outer wall of the flow guide cylinder is attached to the inner wall of the horizontal pipe, and helical blades are arranged on the inner wall of the flow guide cylinder.

[0009] On the basis of the above technical scheme, a raised end portion is arranged at the center of the top surface of the pressure stabilizing plate, and the perforation is arranged in the low area outside the raised end portion.

[0010] On the basis of the above technical scheme, the shunt plate is a horizontal disc structure concentrically arranged in the vertical pipe, the disc structure is fixedly connected to the inner wall of the vertical pipe through a plurality of evenly distributed ribs, the first shunt hole is formed in the gap between adjacent ribs, a plurality of second shunt holes are evenly distributed on the disc, the first sputtering platform and the second sputtering platform are longitudinally and spacedly arranged below the shunt plate, the sputtering curved surface of the first sputtering platform is arranged below the first shunt hole, the sputtering curved surface of the second sputtering platform is arranged below the second shunt hole, and the sewage passing through the first shunt hole and the second shunt hole will flow along the sputtering curved surface of the first sputtering platform and the second sputtering platform to form an outward expanding sputtering waterfall.

[0011] On the basis of the above technical scheme, a plurality of rib plates are arranged at the top of the first sputtering platform, the bottom of the rib plate is connected to the sputtering curved surface of the first sputtering platform, and the top of the rib plate is connected to the bottom of the rib.

[0012] On the basis of the above technical scheme, the top of the second sputtering platform is connected to the center of the bottom of the shunt plate through a connecting column.

[0013] On the basis of the above technical scheme, the elastic member is made of an elastic material, and the elastic member comprises an outer frame with a rectangular structure in longitudinal profile, and a shock absorption cavity is arranged in the inner part of the outer frame.

[0014] On the basis of the above technical scheme, the damping cavity is provided with a plurality of support sheets, the support sheet is an annular vertical sheet structure, and the upper and lower ends of the support sheet are respectively connected and fixed with the upper and lower sides of the outer frame.

[0015] On the basis of the above technical scheme, the bottom of the support sheet is connected with a support seat of an annular structure, and the top of the support seat is distributed with the top of the outer frame.

[0016] On the basis of the above technical scheme, the damping cavity is provided with a pleated sheet, the pleated sheet is an annular pleated structure, the inside of the pleated sheet has a plurality of longitudinal flexible cavities, the transverse width of the flexible cavities is large and small in the longitudinal direction and alternates in cycles, and the upper and lower ends of the sheet are respectively connected with the upper and lower sides of the outer frame.

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

[0018] 1. The uniform pressure and flow stabilizing water distribution device can automatically adjust the flow according to the sewage pressure at each branch pipe by the cooperation of the pressure stabilizing plate and the elastic member. When the pressure at a branch pipe is relatively large, the pressure stabilizing plate moves downward to press the elastic member, and the elastic member provides an upward counteracting force to the pressure stabilizing plate due to its own characteristics. This cooperation makes different water pressures receive different degrees of resistance, forming a water pressure automatic adjustment structure. This automatic adjustment mechanism can effectively overcome the differences in outflow water pressure caused by the different distances of the branch pipes from the inlet end of the branch pipe, so that the internal flow and outflow of each branch pipe tend to be balanced, thereby improving the uniformity of water distribution.

[0019] 2. By designing the shunt plate and the sputtering platform, the sewage forms an outward expanding sputtering waterfall when flowing out of the vertical pipe, greatly increasing the water distribution area, so that the sewage can be more widely input into the filter tank, avoiding the problem of too concentrated water distribution area, and further improving the uniformity of water distribution.

[0020] 3. The water flow changes direction after the bend, and at the same time, the water flow is prone to imbalance inside and outside the bend. The water flow speed is larger on the outer side of the bend and smaller on the inner side of the bend, and the water flow is prone to disorder. By setting a tapered pipe with a narrow top and a wide bottom at the bottom of the bend, according to the wall attachment effect of fluid and the principle of fluid mechanics, the water flow out of the bend will flow along the tapered pipe. The tapered pipe not only reduces the flow resistance, but also restores the uniformity of the water flow, reduces the imbalance of the impact on the pressure stabilizing plate, and improves the uniform pressure and flow effect. Finally, the water flow is further distributed more uniformly in the output area of the branch pipe by the shunt of the shunt plate, which can effectively improve the water distribution uniformity of the water distributor and ensure the water distribution effect.

DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0036] In the description of the present application, the terms "first", "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

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

[0038] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0039] Example 1: Combination Figures 1-10As shown, the embodiment discloses a pressure equalizing and flow stabilizing water distribution device, aiming to solve the problem of uneven internal flow and outflow of some existing water distribution devices due to different distances between the shunt pipes 2 and the water inlet end 11 of the branch pipe 1. Through innovative structural design, each shunt pipe 2 can automatically adjust the internal flow when facing different water inlet pressure, thereby achieving uniform water distribution and flow stabilization effect and improving the overall performance of the sewage treatment system.

[0040] Specifically, the pressure equalizing and flow stabilizing water distribution device comprises a branch pipe 1, the axial one end of the branch pipe 1 is an open structure water inlet end 11 for connecting the sewage to be treated, and the axial other end of the branch pipe 1 is a closed end 12 which is closed by a plug to prevent sewage leakage. The branch pipe 1 is connected with a plurality of shunt pipes 2 along its axial direction, Figure 1 As shown in the middle, a branch pipe 1 is connected with five shunt pipes 2 on the left and right sides, and the adjacent shunt pipes 2 are distributed at intervals. The shunt pipe 2 is used to divide and direct the sewage in the branch pipe 1.

[0041] Combined with Figure 2 and Figure 3 As shown, the shunt pipe 2 comprises a horizontal pipe 21, the input end of the horizontal pipe 21 is communicated with the inside of the branch pipe 1 to ensure that the sewage can smoothly enter the shunt pipe 2 from the branch pipe 1. The output end of the horizontal pipe 21 is connected with an elbow 22, the output end of the elbow 22 is vertically downward and connected with a tapered pipe 23 which is narrow at the top and wide at the bottom. This design helps to guide the flow of sewage and gradually increase the flow area. The bottom of the tapered pipe 23 is connected with a vertical pipe 24, which is the final output channel of the sewage in the water distribution device.

[0042] Further, combined with Figure 5 , Figure 6 and Figure 8 The inner wall of the vertical pipe 24 is provided with a horizontal inner convex and annular structure boss 241, which is welded and fixed on the inner wall of the vertical pipe 24. It should be noted that the top of the boss 241 is a horizontal end face structure. The top of the boss 241 is movably connected with a horizontally arranged pressure stabilizing plate 3, and the radial outer edge of the pressure stabilizing plate 3 is attached to the inner wall of the vertical pipe 24, which constitutes a limiting structure, so that the pressure stabilizing plate 3 has high stability when sliding up and down and will not easily tilt and deviate. The radial outer edge of the pressure stabilizing plate 3 is provided with a "T" type clamping edge 31, and the bottom of the clamping edge 31 is clamped on the top of the boss 241 through the elastic element 5. The elastic element 5 in this embodiment 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 which plays a major role in work, and the specific design is combined with the clever design of its own material properties and physical structure, and it does not mean that it does not have elastic expansion function in other directions.

[0043] As Figure 9 and Figure 10It is to be noted that the cross-sectional structure shown in the figure is only the single-side structure of the elastic member 5, and the overall profile of the elastic member 5 is actually a circular ring structure. In the embodiment, the elastic member 5 includes an outer frame 51 with a longitudinal cross-sectional profile in the shape of a rectangle, and a shock-absorbing cavity 53 is arranged inside the outer frame 51. Two support pieces 52 are arranged in the shock-absorbing cavity 53 in a transverse and inner-outer spaced manner. The support pieces 52 are annular vertical sheet structures, and the upper and lower ends of the support pieces 52 are respectively connected and fixed to the upper and lower sides of the outer frame 51. The adjacent support pieces 52 are spaced apart. When working, the outer frame 51 and the support pieces 52 share and conduct the downward pressing force of the upper pressure stabilizing plate 3 in the longitudinal direction. Due to the existence of the shock-absorbing cavity 53 and the flexible performance of the support pieces 52, the downward pressing force is converted into partial deformation, achieving the effect of shock absorption and energy absorption. Due to the elastic restoring force of the elastic member 5, an upward counteracting force is generated on the upper pressure stabilizing plate 3, which is inversely proportional to the downward pressing force, and is also proportional to the pressure of the water flow on the pressure stabilizing plate 3. Therefore, the water pressure automatic adjusting structure is formed. This automatic adjusting mechanism can effectively overcome the difference in outflow water pressure caused by the different distances between the shunt pipes 2 and the water inlet end 11 of the branch pipe 1, so as to make the internal flow and outflow of each shunt pipe 2 tend to be balanced, thereby improving the uniformity of water distribution.

[0044] The pressure stabilizing plate 3 is provided with a perforation 33 in the form of a longitudinal through hole structure, for sewage to pass through, as shown in Figure 6 The perforation 33 is in the form of a circular arc strip-shaped through hole structure, and has a transverse inner-outer layered structure. The pressure stabilizing plate 3 is provided with a raised end portion 32 upwardly raised at the central position of the top surface, and the perforation 33 is located at the low position region outside the raised end portion 32. This design is helpful for the sewage to form a certain water flow distribution on the pressure stabilizing plate 3, and can achieve the effect of uniformizing and diffusing the water flow in all directions, so that the sewage flows into the lower part of the vertical pipe 24 through the perforation 33 more uniformly. Moreover, since the distribution position of the perforation 33 is closer to the radial outer edge of the pressure stabilizing plate 3, the stress position of the downward pressure of the water flow on the pressure stabilizing plate 3 is closer to the upper part of the elastic member 5, which is beneficial for the rapid transmission of force.

[0045] In the embodiment, the boss 241 only constitutes a single-side limiting structure below the pressure stabilizing plate 3, and in other embodiments, another boss 241 can be arranged above the pressure stabilizing plate 3 to constitute a double-side limiting structure, further controlling and restricting the up-down movement stroke of the pressure stabilizing plate 3.

[0046] In combination with Figure 2 , Figure 5 , Figure 6 and Figure 7, the inner side of the vertical pipe 24 is spaced apart below the pressure plate 3 and provided with a shunt plate 25, the shunt plate 25 is provided with a plurality of longitudinal through hole structure shunt holes, a plurality of sputtering tables are connected below the shunt plate 25, the sputtering table is a horn-shaped structure with longitudinal profile in the shape of "eight", and the top of the sputtering table is a sputtering curved surface located below the shunt hole. When the sewage passes through the shunt hole, it will impact on the sputtering curved surface of the sputtering table, forming an outward expanding sputtering waterfall, further increasing the water distribution area, making the water distribution more uniform.

[0047] Specifically, the shunt plate 25 is a horizontal disc structure concentrically arranged inside the vertical pipe 24, the disc structure is connected and fixed with the inner wall of the vertical pipe 24 through 6 ribs 253 which are uniformly distributed in a central symmetry, the gap between adjacent ribs 253 constitutes a first shunt hole 251, and a plurality of second shunt holes 252 are uniformly distributed on the disc; the shunt plate 25 is provided below with longitudinally spaced first and second sputtering tables 26 and 27, the sputtering curved surface of the first sputtering table 26 is correspondingly arranged below the first shunt hole 251, and the sputtering curved surface of the second sputtering table 27 is correspondingly arranged below the second shunt hole 252. Since the top of the first sputtering table 26 is connected with the bottom of the shunt plate 25 to form a horizontal inner-outer partition structure, the sewage passing through the first and second shunt holes 251 and 252 will flow along the sputtering curved surfaces of the first and second sputtering tables 26 and 27 respectively to form an outward expanding sputtering waterfall, further expanding the water distribution area and improving the uniformity of water distribution. It should be noted that in this embodiment, the curvature of the sputtering curved surface of the second sputtering table 27 is smaller than that of the sputtering curved surface of the first sputtering table 26, and the length of the sputtering curved surface of the second sputtering table 27 is greater than that of the sputtering curved surface of the first sputtering table 26, forming a stacked structure with narrow top and wide bottom, which is beneficial to the formation of double-layer outward expanding surfaces after sputtering of the sewage, and cooperates with the shunt effect of the shunt plate 25 to split and output the sewage in the same shunt pipe 2, further improving the uniformity and stability of water distribution.

[0048] In order to enhance the stability of the first sputtering table 26, the top of the first sputtering table 26 is provided with 6 rib plates 261, the rib plate 261 is a vertical plate structure, the bottom of the rib plate 261 is connected with the sputtering curved surface of the first sputtering table 26, and the top of the rib plate 261 is connected with the bottom of the rib 253. This connection mode not only ensures the stability of the sputtering table, but also forms a partition structure on the sputtering curved surface of the first sputtering table 26, effectively performing partition design, facilitating the dispersed flow and sputtering of the sewage in various directions, and reducing the influence of uneven sputtering direction caused by structural assembly angle deviation.

[0049] Further, the second sputtering table 27 is connected to the bottom center of the distribution plate 25 by a connecting column 271, which further ensures the stability of the overall structure of the sputtering table, and ensures the spacing between the two sputtering tables, and can also select different specifications of the connecting column 271 according to actual operation requirements to adjust the spacing of the sputtering table and realize different sputtering coverage specifications.

[0050] In addition, in combination with Figure 2 and Figure 4 As shown in the drawings, the horizontal pipe 21 in the embodiment is provided with a flow guide cylinder 4 inside and concentrically, the flow guide cylinder 4 is of an open structure at both axial ends, the outer wall of the flow guide cylinder 4 is arranged in close contact with the inner wall of the horizontal pipe 21, and the inner wall of the flow guide cylinder 4 is provided with spiral blades 41. When the sewage flows into the horizontal pipe 21 from the branch pipe 1, the spiral blades 41 will have a guiding effect on the sewage, so that the sewage forms a spiral flow in the horizontal pipe 21, which is helpful to utilize the vortex to generate the centripetal effect of water flow gathering, improve the water flow speed, make the sewage more smooth and stable when entering the distribution pipe 2 from the branch pipe 1, and is conducive to the sewage entering each distribution pipe 2 more uniformly, and is also conducive to weakening the imbalance phenomenon when the water flow 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 cross pipe 21 is defined as the distribution cavity b, the inner cavity of the elbow 22 is defined as the guide cavity c, the inner cavity of the taper pipe 23 is defined as the slow flow cavity d, and the inner cavity of the vertical pipe 24 is defined as the homogenizing cavity e. In the specific implementation process, sewage enters the water inlet cavity a from the input end of the branch pipe 1 and gradually flows into the distribution cavity b. The vortex is formed in the distribution cavity b under the influence of the flow guide cylinder 4, and then enters the slow flow cavity d through the guide cavity c. The sewage in the slow flow cavity d is homogenized for the first time and stably flows downward through the perforations 33 of the pressure stabilizing plate 3 into the homogenizing cavity e. During this process, the downward pressure generated by the pressure stabilizing plate 3 on the elastic member 5 is affected by the size of the water flow. The elastic member 5 generates a corresponding counterforce according to the pressure intensity, and the pressure stabilizing plate 3 applies a pushing force. This forms the resistance of the water flow to achieve automatic water pressure regulation and achieve the effect of pressure stabilization and flow stabilization of the distribution pipe 2 at different positions. The sewage entering the homogenizing cavity e then passes through the first distribution hole 251 and the second distribution hole 252 to form a splashing waterfall along the first splashing platform 26 and the second splashing platform 27, respectively, to output with a larger water distribution area. The pressure stabilization and flow stabilization water distribution device of the present application effectively solves the problem of uneven flow caused by the position difference of the distribution pipe 2 through the innovative design of the pressure stabilizing plate 3, the elastic member 5, the distribution plate 25 and the splashing platform. The device not only realizes the balanced regulation of the flow in each distribution pipe 2, but also significantly improves the uniformity of water distribution and the sewage treatment effect by expanding the water distribution area and improving the stability of the water flow. Compared with the prior art, the present application has the advantages of flow regulation mechanism innovation, significant improvement of water distribution uniformity, enhanced system stability and wide application range, and has broad market application prospect and promotion value. In the future field of sewage treatment, the device is expected to become one of the important equipment for improving the efficiency and quality of sewage treatment.

[0052] Example 2: Based on example 1, combined with Figure 11 As shown in the figure, in this embodiment, the support piece 52 is connected with a ring-shaped support seat 54 at the bottom, the support seat 54 is a "T" type structure, the top beam of the support seat 54 is connected with the inner wall of the outer frame 51 and the outer side wall of the support piece 52 respectively, and the top of the support seat 54 is distributed in the top of the outer frame 51. This structure makes the structure of the elastic member 5 layered, when receiving a small extrusion force, the support piece 52 and the outer frame 51 conduct force alone, when receiving a large extrusion force, the support piece 52 and the outer frame 51 deform to a threshold value, and then the support seat participates in the force conduction, so that the pressure response of the elastic member 5 presents a hierarchical effect, which is beneficial to improve the working mode diversification of the elastic member 5. The support seat 54 can also provide additional support for the support piece 52 to prevent the support piece 52 from deforming when receiving a large pressure, thereby prolonging the service life of the elastic member 5.

[0053] Example 3: Based on example 1, combined with Figure 12As shown, in the embodiment, the shock-absorbing cavity 53 is provided with a pleated sheet 55, which is a ring-shaped pleated structure, and has a plurality of longitudinal flexible cavities 56 inside. The flexible cavities 56 are alternately arranged in a large-small cycle in the transverse direction, and the upper and lower ends of the pleated sheet 55 are connected to the upper and lower sides of the outer frame 51, respectively. The design of the pleated sheet 55 can further increase the shock-absorbing effect of the elastic member 5, so that the pressure stabilizing plate 3 can move up and down more stably when subjected to the pressure change of sewage, and the accuracy of flow regulation is improved.
