Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a vertical flow sedimentation filter device. Background Technology

[0002] Vertical flow sedimentation tanks are important solid-liquid separation devices widely used in wastewater treatment, industrial circulating water purification and other fields. The working principle is that water flows from bottom to top into the central flow stabilizing pipe, rises evenly after being guided, and under the action of gravity, suspended particles settle to the bottom, while clear water is discharged from the upper overflow weir.

[0003] First, the existing equipment does not have a filtration device between the overflow weir and the outlet pipe, which causes some fine suspended particles that have not completely settled to flow out with the clean water, resulting in substandard effluent quality and affecting the stability of subsequent treatment processes or reuse systems.

[0004] Secondly, the existing structure does not have a protective device at the flow stabilizer. Under conditions of strong water flow impact or large water level changes, the water flow is prone to splashing or forming turbulence when entering the flow stabilizer. This not only makes the operating environment slippery, but may also affect the uniformity of the effluent and reduce the overall sedimentation efficiency.

[0005] Therefore, it is necessary to provide a vertical flow sedimentation filter device to solve the problems in the background art described above. Utility Model Content

[0006] To address the aforementioned problems, this application provides a vertical flow sedimentation filter device to solve the issues raised in the background art, namely, the lack of filtration measures between the overflow weir and the outlet pipe, and the lack of anti-splash structure at the flow stabilizer.

[0007] To achieve the objectives of this application, the following technical solution is provided:

[0008] This application provides a vertical flow sedimentation filter device, comprising: a main housing, a drain grate, filter cotton, and filter brushes. An annular mounting plate is fixedly arranged circumferentially inside the main housing. An overflow weir is fixedly arranged circumferentially on the inner side of the annular mounting plate. Multiple support plates are evenly fixedly arranged circumferentially on the inner side of the overflow weir. The ends of the support plates away from the overflow weir are all fixedly connected to a flow stabilizer. A water outlet pipe is installed on the main housing at the upper end of the annular mounting plate. The inlet end of the water outlet pipe is located between the main housing and the overflow weir. An L-shaped inlet pipe is installed on the main body located at the lower end of the overflow weir. The outlet end of the L-shaped inlet pipe is located inside the flow stabilizing cylinder. A drain grate and filter cotton are arranged sequentially from bottom to top on the annular mounting plate on the outer circumference of the overflow weir. At least two filter brushes are provided on the support plate. Multiple support rods are evenly fixed on the circumference of the flow stabilizing cylinder above the uppermost filter brush. The upper ends of the support rods are all fixed to the umbrella-shaped caps, and the lower ends of the support rods all abut against the upper ends of the uppermost filter brushes.

[0009] In one possible implementation, a sedimentation hopper is fixedly installed on the main tank located at the lower end of the L-shaped water inlet pipe, and a drain pipe is installed at the lower end of the sedimentation hopper.

[0010] In one possible implementation, the drain grate includes: a grate body, a through hole is provided at the axial center of the grate body, and an annular groove is provided on the grate body between the through hole and the circumferential direction of the grate body. Multiple evenly distributed drain holes are provided on one end face of the grate body and in the circumferential direction.

[0011] In one possible implementation, the outer diameter of the grate is equal to the inner diameter of the main box, and the diameter of the through hole is equal to the outer diameter of the overflow weir.

[0012] In one possible implementation, the filter cotton includes an annular cotton plate, wherein a through hole is provided at the axial center of the annular cotton plate.

[0013] In one possible implementation, the outer diameter of the annular cotton board is equal to the inner diameter of the main box, and the diameter of the second through hole is equal to the outer diameter of the overflow weir.

[0014] In one possible implementation, the filter brush includes: a mounting ring, wherein a through hole is provided in the circumferential direction of the mounting ring, and bristles are provided in the circumferential direction of the mounting ring.

[0015] In one possible implementation, the diameter of the third through hole is equal to the outer diameter of the flow stabilizer, the ends of the bristles away from the flow stabilizer are all in circumferential contact with the inner side of the overflow weir, and the upper ends of the uppermost mounting rings are all in contact with the lower ends of the support rods.

[0016] In one possible implementation, the overflow weir includes a cylindrical section fixedly disposed with the annular mounting plate. The upper end of the cylindrical section is provided with a serrated portion. The sum of the axial heights of the grate and the annular cotton plate is less than the height of the cylindrical section located at the bottom end of the serrated portion and the upper end of the annular mounting plate. The sum of the overall axial heights of the mounting ring is less than the height of the cylindrical section located at the bottom end of the serrated portion and the upper end of the support plate.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model sets at least two filter brushes between the overflow weir and the flow stabilizer, and sets a drain grate and filter cotton between the outlet pipe and the overflow weir. The settled water can be discharged sequentially through the filter brushes, filter cotton, drain grate and outlet pipe, forming a multi-stage filtration system. This system can effectively intercept suspended particles of different sizes, reduce the risk of unsettled particles entering subsequent treatment stages or being discharged, and significantly improve the quality of the effluent.

[0019] 2. This utility model has a support rod circumferentially set on the upper end of the filter brush. The support rod can limit the upper end of the filter brush, thereby restricting the free swing of the filter brush. At the same time, the umbrella-shaped cap set on the support rod can effectively block the water flow that sprays upward from the L-shaped water inlet pipe. Especially when the water pressure is high, it can effectively prevent sewage from splashing out directly. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.

[0033] Figures 1-9A vertical flow sedimentation filter device provided in this application includes: a main housing 1, a drain grate 7, filter cotton 8, and filter brush 9. An annular mounting plate 101 is fixedly arranged circumferentially inside the main housing 1. An overflow weir 2 is fixedly arranged circumferentially on the inner side of the annular mounting plate 101. Multiple support plates 3 are evenly fixedly arranged circumferentially on the inner side of the overflow weir 2. The ends of the support plates 3 away from the overflow weir 2 are fixedly connected to a flow stabilizer 4. A water outlet pipe 5 is installed on the main housing 1 at the upper end of the annular mounting plate 101. The inlet end of the water outlet pipe 5 is located between the main housing 1 and the overflow weir 4. In the overflow weir 2, an L-shaped water inlet pipe 6 is installed on the main box 1 located at the lower end of the overflow weir 2. The outlet end of the L-shaped water inlet pipe 6 is located inside the flow stabilizing cylinder 4. A water leakage grate 7 and a filter cotton 8 are arranged sequentially from bottom to top on the annular mounting plate 101 located on the outer circumference of the overflow weir 2. At least two filter brushes 9 are provided on the support plate 3. Multiple support rods 10 are evenly fixedly arranged on the circumference of the flow stabilizing cylinder 4 above the uppermost filter brush 9. The upper ends of the support rods 10 are all fixedly arranged with umbrella-shaped caps 11, and the lower ends of the support rods 10 are all in contact with the upper ends of the uppermost filter brush 9.

[0034] Through the above technical solution, the sewage pipe is first connected to the L-shaped inlet pipe 6. The sewage enters the flow stabilizing cylinder 4 from the L-shaped inlet pipe 6. At this time, the sewage flows down along the inner wall of the flow stabilizing cylinder 4 and enters the interior of the main tank 1. The impurities in the sewage settle evenly to the bottom of the main tank 1, while a small amount of suspended impurities rise with the supernatant and can be removed by the filter brush 9. At this time, the supernatant after the first filtration enters the space between the main tank 1 and the overflow weir 2 along the overflow weir 2. The supernatant after the first filtration passes through the filter cotton 8 again to filter the small particles. The supernatant after the second filtration is discharged from the outlet pipe 5 along the drain grate 7.

[0035] Based on the above technical solution, by setting at least two filter brushes 9 between the overflow weir 2 and the flow stabilizer 4, and by setting a drain grate 7 and filter cotton 8 between the outlet pipe 5 and the overflow weir 2, the settled water can be discharged sequentially through the filter brushes 9, filter cotton 8, drain grate 7, and outlet pipe 5, forming a multi-stage filtration system. This system can effectively intercept suspended particles of different sizes, reduce the risk of unsettled particles entering subsequent treatment stages or being discharged, and significantly improve the quality of the effluent.

[0036] In addition, by setting a support rod 10 around the uppermost filter brush 9 on the flow stabilizing cylinder 4, the support rod 10 can limit the upper end of the filter brush 9, thereby restricting the free swing of the filter brush 9. At the same time, the umbrella-shaped cap 11 set on the support rod 10 can effectively block the water flow that sprays upward from the L-shaped water inlet pipe 6. Especially when the water pressure is high, it can effectively prevent sewage from splashing directly outward.

[0037] In one possible implementation, a sedimentation hopper 12 is fixedly installed on the main tank 1 located at the lower end of the L-shaped water inlet pipe 6. A drain pipe 13 is installed at the lower end of the sedimentation hopper 12. It should be noted that a valve is installed in the drain pipe 13. After all the sewage entering the main tank 1 has been discharged, the valve in the drain pipe 13 can be opened. With the cooperation of external high-pressure water, the impurities deposited in the main tank 1 and the sedimentation hopper 12 can be discharged.

[0038] In one possible implementation, the drain grate 7 includes: a grate body 71, a through hole 72 extending through the axial position of the grate body 71, and an annular groove 73 formed on the grate body 71 between the through hole 72 and the circumferential direction of the grate body 71; and a plurality of evenly distributed drain holes 74 formed on one end face and circumferentially of the grate body 71.

[0039] In one possible implementation, the outer diameter of the grate 71 is equal to the inner diameter of the main box 1, and the diameter of the through hole 72 is equal to the outer diameter of the overflow weir 2.

[0040] Using the above technical solution, during the installation of the drain grate 7, first place the end of the grate body 71 with the annular groove 73 on the end face below, then align the through hole 72 with the circumference of the overflow weir 2, slowly release the grate body 71, and finally place the lower end of the grate body 71 on the upper end of the annular mounting plate 101.

[0041] In one possible implementation, the filter cotton 8 includes an annular cotton plate 81, with a through hole 82 extending through the axial center of the annular cotton plate 81.

[0042] In one possible implementation, the outer diameter of the annular cotton board 81 is equal to the inner diameter of the main box 1, and the diameter of the through hole 82 is equal to the outer diameter of the overflow weir 2.

[0043] Using the above technical solution, during the installation of the filter cotton 8, first align the through hole 82 with the overflow weir 2 circumferentially, then slowly release the annular cotton plate 81, place the lower end of the annular cotton plate 81 on the upper end of the grate body 71, and the grate body 71 can support the annular cotton plate 81 so that the water flow between the outlet pipe 5 and the overflow weir 2 can be filtered through the annular cotton plate 81, and the filtered water flow then enters the outlet pipe 5 along the leakage hole 74.

[0044] In one possible implementation, the filter brush 9 includes: a mounting ring 91, which has a through hole 92 extending through its circumference, and bristles 93 arranged in its circumference.

[0045] In one possible implementation, the diameter of the through hole 92 is equal to the outer diameter of the flow stabilizer 4, the ends of the bristles 93 away from the flow stabilizer 4 are all in circumferential contact with the inner side of the overflow weir 2, and the upper end of the uppermost mounting ring 91 is in contact with the lower end of the support rod 10.

[0046] Using the above technical solution, taking two filter brushes 9 as an example, during the installation of the filter brushes 9, first align the through hole 3 92 of one filter brush 9 with the circumference of the flow stabilizer 4, then slowly release the mounting ring 91, place the lower end of the mounting ring 91 on the upper end of the support plate 3, then align the through hole 3 92 of the other filter brush 9 with the circumference of the flow stabilizer 4, slowly release the mounting ring 91 of the filter brush 9, place the lower end of the mounting ring 91 on the upper end of the mounting ring 91 where the filter brush 9 was initially placed, then sequentially abut the bottom of the support rod 10 against the upper end of the uppermost mounting ring 91, and fix the support rod 10 to the circumference of the flow stabilizer 4, and finally fix the umbrella-shaped cap 11 on each support rod 10.

[0047] In one possible implementation, the overflow weir 2 includes a cylindrical section fixedly disposed with the annular mounting plate 101. The upper end of the cylindrical section is provided with a serrated section. The sum of the axial heights of the grate 71 and the annular cotton plate 81 is less than the height of the cylindrical section located at the bottom end of the serrated section and the upper end of the annular mounting plate 101. The sum of the overall axial heights of the mounting ring 91 is less than the height of the cylindrical section located at the bottom end of the serrated section and the upper end of the support plate 3. This allows the supernatant after the initial filtration to enter the space between the main box 1 and the overflow weir 2 along the serrated section of the overflow weir 2, and then undergo secondary filtration through the filter cotton 8.

[0048] Working principle:

[0049] Connect the sewage pipe to the L-shaped inlet pipe 6. The sewage enters the flow stabilizer 4 through the L-shaped inlet pipe 6. The sewage then flows down the inner wall of the flow stabilizer 4 into the main tank 1. Impurities in the sewage settle evenly into the sedimentation hopper 12, while a small amount of suspended impurities rise with the supernatant and can be removed by the brush bristles 93. The supernatant after the first filtration then enters the space between the main tank 1 and the overflow weir 2 through the serrated part of the overflow weir 2. The supernatant after the first filtration is filtered again by the annular cotton plate 81 to remove small particles. The supernatant after the second filtration is discharged from the outlet pipe 5 through the drain hole 74. After all the sewage is discharged, open the valve in the drain pipe 13 to discharge the impurities deposited in the main tank 1 and the sedimentation hopper 12.

[0050] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
