AI Technical Summary
After a long drainage of water, the existing radial sedimentation tank will have a smaller flow rate due to scaling inside the buried pipe, resulting in overflow. The buried pipe cannot be effectively cleaned, which will affect the normal operation of the radial sedimentation tank.
A radial precipitation tank for overflow is designed. By setting up a three-way pipe at one end of the overflow outflow pipe, the buried pipe and the backup overflow pipe are connected together to ensure that even if the buried pipe is reduced due to the scale flow, the backup overflow pipe can still be drained. At the same time, a filter tube and a collection cylinder are installed for preliminary filtration to ensure that the water flow is clean and through the communication tube, ensuring that the water can still be discharged normally when the collection cylinder is blocked.
By setting up a spare overflow pipe, the radial sedimentation tank can still effectively drain water when the underground pipe is scaled, preventing the occurrence of overflow. The design of the filter tube and collection cartridge effectively avoids drainage problems caused by dirt accumulation, ensuring the convenience of normal operation and maintenance of the drainage system.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radial flow sedimentation tanks, in particular to an overflow-proof radial flow sedimentation tank. Background Art
[0002] A radial flow sedimentation tank is one of the equipment used to treat sewage or wastewater, usually used to remove suspended matter, sediment and other solid particles. In a radial flow sedimentation tank, the water flow is slowed down so that suspended matter can settle to the bottom, thereby purifying the water. The overflow pipe is an important component of the radial flow sedimentation tank. Its main function is to control the water level and ensure that excess water can be discharged smoothly when the water level reaches a certain height. The overflow pipe is usually set at the top of the radial flow sedimentation tank. When the water level exceeds the set height, the water will be discharged through the overflow pipe, thereby preventing the radial flow sedimentation tank from overflowing.
[0003] The overflow pipe of the existing radial flow sedimentation tank is connected to the buried pipe and drains water through the buried pipe. However, after a long period of drainage, the flow rate will decrease due to scaling inside the buried pipe, and the radial flow sedimentation tank will overflow.
[0004] Since buried pipes are usually buried underground, they cannot be effectively cleaned after scaling occurs. In this case, the overflow pipe cannot effectively drain water, which will affect the normal operation of the entire radial flow sedimentation tank. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides an overflow-proof radial flow sedimentation tank. The technical solution of the utility model is as follows:
[0006] An overflow-proof radial flow sedimentation tank comprises a radial flow sedimentation tank body and a spare overflow pipe, wherein an overflow outlet pipe is fixedly connected to the front side of the radial flow sedimentation tank body, the front end of the overflow outlet pipe is connected to a tee pipe through a bolt flange, the left side of the tee pipe is connected to an underground pipe through a bolt flange, the right side of the tee pipe is connected to the spare overflow pipe through a bolt flange, the front side of the spare overflow pipe is fixedly connected to a guide pipe, one end of the guide pipe is connected to a connecting pipe through a bolt flange, the lower end of the spare overflow pipe is connected to an upper manual valve through a bolt flange, the lower end of the upper manual valve is connected to a connecting pipe through a bolt flange, the lower end of the connecting pipe is connected to a filter pipe through a bolt flange, the lower end of the filter pipe is connected to a flow meter through a bolt flange, the lower end of the flow meter is connected to a lower manual valve through a bolt flange, the lower end of the lower manual valve is connected to the outlet pipe through a bolt flange, the front side of the outlet pipe is fixedly connected to a downpipe, and the lower end of the connecting pipe is flange-connected to the downpipe.
[0007] Optionally, the guide pipe is arranged at an angle, and the angle between the guide pipe and the spare overflow pipe is 30 degrees to 60 degrees.
[0008] Optionally, the topmost height of the connecting pipe is lower than the height of the overflow outlet pipe.
[0009] Optionally, a mounting groove is provided on the edge of the upper surface of the filter tube, a collecting cylinder is movably placed inside the filter tube, an annular seat is fixedly connected to the periphery of the upper surface of the collecting cylinder, and the collecting cylinder is movably placed inside the mounting groove through the annular seat.
[0010] Optionally, both sides of the upper end of the inner wall of the collecting cylinder are fixedly connected with fixing seats, and the inner sides of the two groups of fixing seats are rotatably connected with handles.
[0011] Optionally, a holder is fixedly connected to one side of the inner wall of the collecting tube, and the handle slot is installed on the holder.
[0012] Optionally, the lower surface of the collecting tube is inclined, and a plurality of filter holes are formed through the lower surface of the collecting tube.
[0013] All the above optional technical solutions can be combined arbitrarily, and the present utility model does not provide detailed descriptions of the structures after the combinations.
[0014] By means of the above scheme, the beneficial effects of the utility model are as follows:
[0015] 1. Through the setting of the spare overflow pipe, the spare overflow pipe and the buried pipe are connected to one end of the overflow outlet pipe through a tee pipe. This structure allows the overflow outlet pipe and the spare overflow pipe to be used for drainage at the same time, thereby improving the drainage efficiency. When the flow rate decreases due to scaling inside the buried pipe, even if the buried pipe is difficult to clean, the spare overflow pipe can still maintain the drainage function. This design ensures that even if there is a problem with the buried pipe, the radial flow sedimentation tank body can still effectively drain water, effectively preventing the occurrence of overflow.
[0016] 2. Through the setting of the filter pipe, after the water flows into the filter pipe through the spare overflow pipe, the collection tube in the filter pipe can intercept large particles of impurities or dirt in the water, playing a role of preliminary filtration. Subsequently, the water flow after preliminary filtration will continue to be discharged through the outlet pipe. This design avoids the influence of scaling on the outlet pipe after long-term drainage work. Through such a setting, the drainage system can maintain a good operating state and reduce drainage problems caused by dirt accumulation.
[0017] 3. Through the setting of the connecting pipe, when the collection tube is blocked, the water will overflow the filter tube and flow into the outlet pipe through the connecting pipe, ensuring the normal operation of the drainage system and providing time guarantee for subsequent staff to clean the collection tube, effectively dealing with possible blockages and ensuring the continuous operation and maintenance convenience of the drainage system.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] See also Figure 1-5As shown, the utility model provides an overflow-proof radial flow sedimentation tank, comprising a radial flow sedimentation tank body 1 and a spare overflow pipe 4, the front side of the radial flow sedimentation tank body 1 is fixedly connected with an overflow outlet pipe 2, the front end of the overflow outlet pipe 2 is connected with a tee pipe 21 through a bolt flange, the left side of the tee pipe 21 is connected with a buried pipe 3 through a bolt flange, the right side of the tee pipe 21 is connected with a spare overflow pipe 4 through a bolt flange, the front side of the spare overflow pipe 4 is fixedly connected with a guide pipe 41, one end of the guide pipe 41 is connected with a connecting pipe 5 through a bolt flange, and the spare overflow pipe 4 is fixedly connected with a guide pipe 41. The lower end of the flow tube 4 is connected to an upper manual valve 6 through a bolt flange, the lower end of the upper manual valve 6 is connected to a connecting pipe 7 through a bolt flange, the lower end of the connecting pipe 7 is connected to a filter pipe 8 through a bolt flange, the lower end of the filter pipe 8 is connected to a flow meter 9 through a bolt flange, the lower end of the flow meter 9 is connected to a lower manual valve 10 through a bolt flange, the lower end of the lower manual valve 10 is connected to a water outlet pipe 11 through a bolt flange, the front side of the water outlet pipe 11 is fixedly connected to a downpipe 111, and the lower end of the connecting pipe 5 is flange-connected to the downpipe 111;
[0027] The utility model is provided with a set of structures including a spare overflow pipe 4 without destroying the original buried pipe 3, and the buried pipe 3 and the spare overflow pipe 4 can complete the drainage work together. When the scale flow inside the buried pipe 3 becomes smaller, the water inside the radial flow sedimentation tank body 1 can still be discharged through the spare overflow pipe 4. A filter pipe 8 is installed below the spare overflow pipe 4, and a collection tube 82 is placed inside the filter pipe 8, which can perform preliminary filtration on the water flowing through the filter pipe 8 to intercept large particles of impurities or dirt inside the collection tube 82. The flow meter 9 can monitor the flow of water flowing down from the filter pipe 8 in real time. When the flow meter 9 detects that the water flow has become smaller, it indicates that the inside of the collection tube 82 is blocked and needs to be cleaned manually. At the same time, when the collection tube 82 is completely blocked, the water will flow directly from the spare overflow pipe 4 into the connecting pipe 5, and finally drained from the outlet pipe 11, ensuring normal drainage work and gaining cleaning time for the staff.
[0028] Furthermore, the guide pipe 41 is arranged in an inclined manner, and the angle between the guide pipe 41 and the spare overflow pipe 4 is 30 degrees to 60 degrees; when the water flows to the spare overflow pipe 4, the water will preferentially flow into the upper manual valve 6, and then flow into the filter pipe 8 through the connecting pipe 7, and the impurities will be collected and filtered by the collecting cylinder 82 inside the filter pipe 8. The purpose of this design is to ensure that when the filter pipe 8 is not blocked, the water will not enter the connecting pipe 5 through the guide pipe 41, thereby avoiding the inability to effectively filter the water. At the same time, the guide pipe 41 is arranged in an inclined manner, and the angle between it and the spare overflow pipe 4 is between 30 degrees and 60 degrees, which can ensure that when the collecting cylinder 82 is in an unobstructed state, the water will not flow into the guide pipe 41. When the collecting cylinder 82 is blocked, the water can flow from the guide pipe 41 into the connecting pipe 5.
[0029] Furthermore, the top of the connecting pipe 5 is lower than the height of the overflow outlet pipe 2; when the collecting tube 82 is blocked, the water overflows the filter pipe 8 and gradually overflows. At this time, the height of the connecting pipe 5 is lower than the height of the overflow outlet pipe 2, and the overflowing water will flow into the connecting pipe 5 instead of flowing back to the overflow outlet pipe 2, thereby avoiding the occurrence of overflow of the radial flow sedimentation tank body 1.
[0030] Furthermore, an installation groove 81 is opened on the edge of the upper surface of the filter tube 8, and a collecting cylinder 82 is movably placed inside the filter tube 8. An annular seat 821 is fixedly connected to the outer periphery of the upper surface of the collecting cylinder 82, and the collecting cylinder 82 is movably placed inside the installation groove 81 through the annular seat 821; this movable installation method not only simplifies the installation process of the collecting cylinder 82, but also makes it convenient for the staff to clean the impurities and dirt inside it.
[0031] Furthermore, both sides of the upper end of the inner wall of the collecting cylinder 82 are fixedly connected with fixing seats 822, and the inner sides of the two sets of fixing seats 822 are rotatably connected with handles 823; since the annular seat 821 and the mounting groove 81 are in a basically matching state, when the staff needs to take out the collecting cylinder 82, the collecting cylinder 82 can be easily taken out by the handles 823.
[0032] Furthermore, a holder 824 is fixedly connected to one side of the inner wall of the collecting cylinder 82, and a slot of the handle 823 is installed at the upper end of the holder 824; after the cleaning is completed and the collecting cylinder 82 is placed inside the filter tube 8, the handle 823 is connected to the holder 824 to fix the position of the handle 823, which can effectively avoid frequent flushing of the handle 823 during the flow of water, thereby preventing impurities and dirt in the water from adhering to the outside of the handle 823.
[0033] Furthermore, the lower surface of the collecting cylinder 82 is inclined, and a plurality of filter holes 825 are formed through the lower surface of the collecting cylinder 82; the lower surface of the collecting cylinder 82 is arranged in an inclined state, thereby increasing the filterable area of the water body, and the filter holes 825 can ensure the smooth flow of the water body while intercepting large particles of impurities and dirt.
[0034] Working principle: The water in the radial flow sedimentation tank body 1 flows to the inside of the tee pipe 21 through the overflow outlet pipe 2. At this time, the water will flow to the buried pipe 3 and the spare overflow pipe 4. If the buried pipe 3 is scaled, the flow rate will decrease. At this time, the spare overflow pipe 4 can still serve the purpose of drainage.
[0035] The spare overflow pipe 4 is provided with two flow routes. Under normal drainage conditions, the specific flow direction is: spare overflow pipe 4-upper manual valve 6-connecting pipe 7-filter pipe 8 (after the water reaches the filter pipe 8, large particles of impurities or dirt in the water will be collected by the collecting cylinder 82, and the water after preliminary filtration will flow out through the filter hole 825)-flow meter 9-lower manual valve 10-water outlet pipe 11; when there are many impurities in the collecting cylinder 82, the filter hole 825 will be blocked, and the water will not be able to pass through the filter pipe 8. At the same time, the flow meter 9 detects that the water flow rate becomes smaller or there is no flow data, and the staff can clean the collecting cylinder 82 in time;
[0036] After the filter hole 825 is blocked, the water will gradually overflow the filter tube 8 and overflow to the guide tube 41. At this time, the specific flow of the water is: spare overflow pipe 4-connecting pipe 5-outlet pipe 11, ensuring that after the filter hole 825 is blocked, the water can still be effectively drained through the outlet pipe 11, ensuring normal drainage, and at the same time buying enough time for cleaning the collection tube 82;
[0037] When the staff cleans the collection tube 82, they manually close the upper manual valve 6 and the lower manual valve 10. At this time, the water body will be completely drained through the connecting pipe 5 and will no longer flow into the filter tube 8. The filter tube 8 is manually removed, and the collection tube 82 is taken out for cleaning.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
