Description

[Technical Field]

[0001] The present disclosure relates to the field of water treatment, and in particular to settling plates, settling assemblies and settling modules.

[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on October 18, 2021, bearing application number 202111210735.3 and entitled "Lateral-Flow Flat Plate Sedimentation Module," and a Chinese patent application filed with the China Patent Office on December 22, 2021, bearing application number 202111583428.X and entitled "Sedimentation Plate, Sedimentation Assembly and Sedimentation Module," the entire contents of which are incorporated herein by reference. [Background technology]

[0003] The horizontal flow inclined plate sedimentation process is a common process in the water treatment industry, and the pitch between the inclined plates is usually 25mm to 200mm, which is in line with the "shallow pond theory." The horizontal flow inclined plate sedimentation process has high sedimentation efficiency and a high effective utilization rate of the cross section perpendicular to the water flow, reaching an effective utilization rate of over 90%.

[0004] However, in this process, if the width of the slanted plate is greater than 1 m, the thickness is less than 10 mm, and the angle between the slanted plate and the horizontal plane is 60°, the slanted plate will bend. If left unused for a long period of time, creep will occur, affecting the sludge removal efficiency. Therefore, in large water treatment plants, this process often uses slanted plates arranged in multiple bends to effectively utilize the height. As a result, during the sludge removal process, the upper sediment cannot fully adhere to the corners as it slides downward, causing the sediment to disperse and fall back into the water, reducing the sedimentation efficiency. Furthermore, the installation and fixing of the slanted plate is difficult. Due to these drawbacks, the horizontal flow slanted plate sedimentation process has not been widely adopted.

[0005] The horizontal-flow horizontal pipe sedimentation process has been around for many years in the water treatment industry. Compared to the horizontal-flow oblique plate sedimentation process, the horizontal-flow horizontal pipe can divide the water into smaller pieces. The water channels and mud channels are independent and do not interfere with each other, resulting in higher sedimentation efficiency. However, the corners and main oblique plate of the conventional horizontal pipe are diamond-shaped and not vertical, making stamping difficult for mass production. Manual production results in poor quality and high costs. Furthermore, because the water channels and mud channels are relatively far apart, the effective utilization rate of the vertical cross-section of the water flow is only about 60%. These drawbacks prevent the horizontal-flow horizontal pipe sedimentation process from being widely adopted. Summary of the Invention [Problem to be solved by the invention]

[0008] Optionally, the ratio of the height of the first rib to the height of the second rib is 1.5-5.

[0009] Optionally, the material of the precipitation plate is polyolefin.

[0010] Optionally, the spacing between two adjacent said first ribs is smaller than the spacing between two adjacent said second ribs.

[0011] Optionally, a reinforcing rib is further formed on the second surface, extending parallel to the second rib, and protruding therefrom, the height of the reinforcing rib being smaller than the height of the second rib.

[0013] Optionally, the angle between said plate and the bottom surface of said box frame is 60°.

[0014] Optionally, at least a portion of the side beams have a recessed groove that opens obliquely to the bottom surface of the box-shaped frame, and the settling plate is inserted into the recessed groove in close contact with the bottom surface.

[0015] Optionally, a plurality of said side beams are removably connected together by threaded fasteners.

[0016] Optionally, the settling assembly further includes a flushing mechanism for introducing flushing liquid into the mud conveying passage, the flushing mechanism including a bracket fixed above the side beam and a plurality of first wash pipes attached to the bracket, the first wash pipes being horizontally arranged and having first spray nozzles opening downward.

[0017] Optionally, the flushing mechanism further includes a plurality of second wash pipes communicating with the first wash pipe, the plurality of second wash pipes being erected on one side of the box-shaped frame and having second water nozzles directed toward the settling plate.

[0018] Optionally, the second wash pipe is provided on a side of the box frame near an upper end of the settling plate.

[0019] Based on the above technical solution, the present disclosure further provides a sedimentation module including: a housing in which a water inlet, a water outlet, and a mud discharge port are opened; a sedimentation assembly configured as the sedimentation assembly in the above technical solution and provided in the housing; and a sediment treatment mechanism provided below the sedimentation assembly for discharging sediment after settling from the mud discharge port.

[0020] Optionally, the settling module further includes a water distribution mechanism, the water distribution mechanism including a first water distribution plate provided between the water supply side of the settling assembly and the water supply inlet, and a second water distribution plate provided between the water outlet side of the settling assembly and the water outlet, the first water distribution plate and the second water distribution plate dividing the housing into a water supply chamber, a settling chamber accommodating the settling assembly, and a water outlet chamber, and water distribution pipes passing through the first water distribution plate and the second water distribution plate respectively are evenly distributed, thereby connecting two adjacent chambers.

[0021] Optionally, the first water distribution plate and the second water distribution plate are configured as hollow plates having a cavity therein, and a plurality of nozzles communicating with the cavity are provided on the surfaces of the first water distribution plate and the second water distribution plate facing the water flow passage, the positions of the nozzles correspond to the positions of the water flow passage, and water supply pipes for supplying water to the cavity are connected to the first water distribution plate and the second water distribution plate, respectively.

This also simplifies the stamping process, thereby improving production efficiency and reducing production costs. When multiple settling plates are stacked obliquely and sequentially, with the mud conveying passage of each settling plate pointing diagonally upward and the water flow passage pointing diagonally downward, the first ribs of the upper settling plate are perpendicular to the mud conveying passage of the lower settling plate. Therefore, the first ribs do not block the mud conveying passage in the direction of sediment settling, allowing sediment to settle directly and quickly into the mud conveying passage, thereby improving settling efficiency and simultaneously improving the utilization rate of the water flow passage. Furthermore, the second ribs in the mud conveying passage can be blocked in the direction of water flow, preventing sediment settled in the mud conveying passage from reentering the water flow, thereby improving the separation rate of sediment and water. The settling assembly of the present disclosure has the same technical effects as the settling plate in the above technical solution, and to avoid unnecessary duplication, its description will be omitted here. The settling module of the present disclosure has the same technical effects as the settling assembly in the above technical solution, and to avoid unnecessary duplication, its description will be omitted here. In addition, the sediment discharged from the mud conveying passage to the bottom of the housing is quickly discharged from the mud discharge port due to the guiding action of the sediment treatment mechanism, preventing sediment from accumulating on the housing and blocking the mud conveying passage.

[0026]

[0033] Specific embodiments of the present disclosure will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are used only to explain and interpret the present disclosure, and are not intended to limit the present disclosure.

[0027] In this specification, unless otherwise specified, the directional terms "upper" and "lower" generally refer to the upper and lower directions along the direction of gravity, and "inner" and "outer" refer to the inner and outer directions relative to the contours of the corresponding components. Terms such as "first," "second," and the like, used in this specification are used to distinguish one element from another and do not imply any order or significance. In the following description of the drawings, the same or similar elements are designated by the same reference numerals in each drawing unless otherwise specified.

[0028] To achieve the above object, the present invention provides a settling plate 10, which may include a flat plate 101 having opposing first and second surfaces 1011 and 1012, as shown in FIGS. 1 to 4. A plurality of first ribs 102 may be formed vertically on the first surface 1011, parallel to each other and spaced apart, and a plurality of second ribs 103 may be formed vertically on the second surface 1012 of the flat plate 101, parallel to each other and spaced apart. The first ribs 102 are perpendicular to the second ribs 103, and a water flow passage 104 is formed between two adjacent first ribs 102, and a mud transport passage 105 is formed between two adjacent second ribs 103.

[0029] Thanks to the above technical solution, the multiple first ribs 102 and multiple second ribs 103 of the sedimentation plate 10 of the present disclosure are each perpendicular to the flat plate 101, so that the first ribs 102 and the second ribs 103 can function as reinforcing ribs, thereby improving the rigidity of the sedimentation plate 10 and reducing the thickness of the sedimentation plate 10, and also reducing the difficulty of stamping out the sedimentation plate 10 during its production process, which is advantageous for improving production efficiency and reducing production costs. When multiple settling plates 10 are arranged at an angle and stacked one on top of the other, with the mud conveying passage 105 of each settling plate 10 pointing diagonally upward and the water flow passage 104 pointing diagonally downward, the first rib 102 of the upper settling plate 10 is perpendicular to the mud conveying passage 105 of the lower settling plate 10, so that the first rib 102 does not block the mud conveying passage 105 in the direction of sediment settling, and sediment can easily settle directly and quickly in the mud conveying passage 105, thereby improving settling efficiency and at the same time improving the utilization rate of the water flow surface of the water flow passage 104. Furthermore, the second rib 103 in the mud conveying passage 105 can block the water flow direction, preventing sediment settled in the mud conveying passage 105 from re-entering the water flow and thereby improving the separation rate of sediment and water.

[0030] In a specific embodiment of the present invention, the height ratio of the first rib 102 to the second rib 103 may be 1.5 to 5, and the height of the first rib 102 to the second rib 103 means the dimension of the part that protrudes from the flat plate. Preferably, the height ratio of the first rib 102 to the second rib 103 may be 16:9, which increases the cross-sectional area of ​​the water flow passage compared to conventional methods, thereby improving the amount of water flow per unit time and increasing production capacity.

[0031] In a specific embodiment of the present disclosure, the material of the precipitation plate 10 may be polyolefin, specifically PVC, PP, or PE. The precipitation plate 10 made of these materials can be integrally formed by injection molding, and the precipitation plate 10 itself is light in weight, making it easy to transport and assemble. In addition, the precipitation plate 10 made of these materials is more corrosion-resistant and has a long service life.

[0032] As shown in Figures 1 to 4, the distance between two adjacent first ribs 102 may be smaller than the distance between two adjacent second ribs 103, i.e., the width of the mud conveying passage 105 is wider, thereby avoiding clogging after sediment enters the mud conveying passage 105.

[0033] As shown in Figure 1, reinforcing ribs 106 extending parallel to the second ribs 103 are formed on the second surface 1012 to protrude further, increasing the strength of the settling plate 10 and preventing the settling plate 10 from bending and deforming when there is a large amount of sediment. The height of the reinforcing ribs 106 is smaller than the height of the second ribs 103, preventing the reinforcing ribs 106 from interfering with the water flow in the water flow passage 104. In addition, reinforcing ribs perpendicular to the flat plate 101 are formed on the surface of the first ribs 102 to prevent the first ribs 102 from bending and deforming.

[0034] Based on the above technical solution, the present disclosure further provides a settling assembly 1. As shown in Figures 2 to 4, the settling assembly 1 may include a box-shaped frame 11 surrounded by a plurality of side beams 111, and a plurality of settling plates 10 inclined on the box-shaped frame 11. The settling plate 10 may be the settling plate 10 in the above technical solution, with the first surface 1011 facing diagonally downward and the second surface 1012 facing diagonally upward, and between two adjacent settling plates 10, the first rib 102 of one abuts the second rib 103 of the other, thereby forming a water flow passage 104 and a mud conveying passage 105 that are perpendicular to each other between the two adjacent settling plates 10, and the water flow passage 104 is located above the mud conveying passage 105, so that when the water flows through the water flow passage 104, the sediment can be settled in the mud conveying passage 105 by the action of gravity, and the mud conveying passage 105 extends at an inclination downward, and after entering the mud conveying passage 105, the sediment can flow downward along the mud conveying passage 105 and be discharged.

[0035] According to the above technical solution, the settling assembly according to the present disclosure has the same technical effect as the settling plate in the above technical solution, and in order to avoid unnecessary duplication, the description will be omitted here.

[0036] In a specific embodiment of the present disclosure, the water flow direction is the same as the extension direction of the water flow passage 104, and the water flows into the water flow passage 104 at the water inlet side of the settling assembly 1 and out of the water flow passage 104 at the water outlet side of the settling assembly 1. The settling assembly 1 has a cubic structure with approximately 2 m in length, 3.6 m in width, and 1.5 m in height, where the length refers to the dimension along the water flow direction. The settling assembly 1 can have a standard structure, making it easy to transport and install. Furthermore, the water flow velocity through the water flow passage 104 can be 8 mm / s to 10 mm / s to balance settling efficiency and production capacity.

[0037] In a specific embodiment of the present disclosure, the angle between the mud conveying passage 105 and the bottom surface can be larger than the dynamic angle of repose of the soil and sand, so that the angle between the flat plate 101 and the bottom surface of the box-shaped frame 11 can be 60°, thereby avoiding the occurrence of mud accumulation in the mud conveying passage 105.

[0038] To facilitate assembly of the settling assembly 1, at least some of the side beams 111 may have grooves (not shown) that open at an angle to the bottom surface of the box-shaped frame 11, and the settling plate 10 may be inserted closely into the groove to be fixed relatively to the box-shaped frame 11. When the box-shaped frame 11 is assembled with the settling plate 10 inserted into the groove, the difficulty of assembling the settling assembly 1 is reduced and the assembly efficiency of the settling assembly 1 can be improved. In addition, multiple side beams 111 can be detachably connected to each other with screw fasteners, facilitating quick attachment and detachment of the box-shaped frame 11.

[0039] As shown in Figures 2, 3 and 7, the settling assembly 1 may further include a flushing mechanism 12 for introducing flushing liquid into the mud transport passage 105. The flushing mechanism 12 may include a bracket 121 fixed above the side beam 111 and a plurality of first wash pipes 122 attached to the bracket 121. The first wash pipe 122 is horizontally disposed and has a plurality of first spray nozzles 123 that open downward, and the plurality of first spray nozzles 123 are disposed at intervals. The first wash pipe 122 may be connected to a high-pressure water source, so that flushing liquid can be sprayed into the mud transport passage 105 via the first spray nozzles 123. The flushing liquid can flush sediment downward as it flows downward along the mud transport passage 105, thereby accelerating the discharge of sediment.

[0040] As shown in Figures 2, 4 and 7, since the settling plate 10 is inclined relative to the box-shaped frame 11, part of the upper end of the mud transport passage 105 of the settling plate 10 is located on the top surface of the box-shaped frame 11, and the other part of the upper end of the mud transport passage 105 of the settling plate 10 is located on the side of the box-shaped frame 11.Therefore, the flushing liquid cannot be sprayed via the first spray nozzle 123 into the mud transport passage 105 whose upper end is located on the side of the box-shaped frame 11.Therefore, as shown in Figures 2 and 7, the flushing mechanism 12 may further include a plurality of second wash pipes 124 connected to the first wash pipe 122. A plurality of second wash pipes 124 may be erected on one side of the box-shaped frame 11, specifically on the side close to the upper end of the settling plate 10, and may have a second spray nozzle 125 facing the settling plate 10, so that the flushing liquid is sprayed through the second spray nozzle 125 into the mud conveying passage 105, the upper end of which is located on the side of the box-shaped frame 11, thereby allowing the flushing liquid to flush the sediment downward.

[0041] Based on the above technical solution, the present disclosure further provides a sedimentation module. As shown in FIGS. 5 to 8 , the sedimentation module may include a housing 2, a sedimentation assembly 1, and a sediment treatment mechanism 3. The sedimentation assembly 1 may be configured as the sedimentation assembly 1 in the above technical solution, and the sedimentation assembly 1 is provided in the housing 2. The housing 2 may have a water inlet 21, a water outlet 22, and a mud discharge port 23, with the water inlet 21 adjacent to the water supply side of the sedimentation assembly 1, the water outlet 22 adjacent to the water discharge side of the sedimentation assembly 1, and the mud discharge port 23 provided at the bottom of the housing 2. The sediment treatment mechanism 3 may be provided below the sedimentation assembly 1 so as to discharge settled sediment through the mud discharge port 23. Specifically, the sediment treatment mechanism 3 may be a funnel-shaped structure composed of multiple inclined mud transport plates 31, and the mud discharge port 23 may be provided at the bottom of the funnel-shaped structure to facilitate smooth discharge of sediment.

[0042] According to the above technical solution, the sedimentation module of the present disclosure has the same technical effects as the sedimentation assembly 1 in the above technical solution, but to avoid unnecessary duplication, the description will be omitted here. In addition, the sediment discharged from the mud conveying passage 105 to the bottom of the housing 2 can be quickly discharged from the mud discharge port 23 due to the guiding action of the sediment treatment mechanism 3, thereby preventing the sediment from accumulating inside the housing 2 and blocking the mud conveying passage 105.

[0043] As shown in FIG. 7, the settling module may further include a water distribution mechanism 4. As shown in FIGS. 5 to 8, the water distribution mechanism 4 may include a first distribution plate 41 disposed between the water supply side of the settling assembly 1 and the water inlet 21, and a second distribution plate 42 disposed between the water outlet side of the settling assembly 1 and the water outlet 22. As shown in FIG. 6, the first distribution plate 41 and the second distribution plate 42 can divide the housing 2 into a water supply chamber 201, a settling chamber 202 accommodating the settling assembly 1, and a water outlet chamber 203. The first distribution plate 41 and the second distribution plate 42 each have evenly distributed water pipes 43 penetrating them, thereby connecting the two adjacent chambers. Specifically, the evenly distributed multiple water pipes 43 in the first distribution plate 41 allow water in the water supply chamber 201 to flow evenly into the settling chamber 202, allowing the water to flow evenly and gently into the multiple water flow passages 104, thereby facilitating the maintenance of settling stability. In addition, the multiple water distribution pipes 43 evenly distributed in the second water distribution plate 42 allow the water in the settling chamber 202 to enter the water outlet chamber 203 evenly and gently, and after settling, the water can be gently and smoothly discharged from the water outlet 22 to the next process.

[0044] In addition, the first distribution plate 41 and the second distribution plate 42 can be configured as hollow plates having a cavity (not shown) inside, and a plurality of nozzles communicating with the cavity on the sides of the first distribution plate 41 and the second distribution plate 42 facing the water flow passage 104, respectively. 45 A nozzle is provided 45 The positions of the water flow passages 104 correspond to the positions of the water supply pipes for supplying water to the cavities of the first water distribution plate 41 and the second water distribution plate 42. 44 is connected to the water supply pipe.44 is connected to a high-pressure water source, and a high-pressure water flow is directed through the nozzle. 45 The water can be sprayed into the water flow passage 104 via the nozzle, making it easy to flush the water flow passage 104.

[0045] Although the preferred embodiments of the present invention have been described in detail above with reference to the drawings, the present disclosure is not limited to the specific details in the above embodiments, and many simple modifications can be made to the technical means of the present disclosure within the scope of the technical concept of the present disclosure, and all of these simple modifications fall within the protection scope of the present disclosure.

[0046] It should be noted that the specific technical features described in the above specific embodiments may be combined in any suitable manner if not contradictory, and in order to avoid unnecessary duplication, the present disclosure will not re-describe various possible combination manners.

[0047] Furthermore, various embodiments of the present disclosure can be combined in any desired manner, and should be considered as being similarly disclosed in the present disclosure unless they are contrary to the spirit of the present disclosure. [Explanation of symbols]
