DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the practical embodiment clearer, the technical solution in the practical embodiment is clearly and completely described. Obviously, the described embodiment is a part of the practical embodiment, not all of the embodiments. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical.
[0022] The embodiment of the present application provides a drainage device for water conservancy project construction with a filtering function, which solves the problem that the filtering structure is easily clogged by impurities and is difficult to clean, which is not conducive to continuous drainage. When in use, it can automatically clean the debris on the filter screen and collect the debris in the sedimentation box, and can be discharged through the sewage pipe. The structure is simple, it can work continuously, and the drainage efficiency is improved.
[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Reference Figure 1-3 A drainage device for water conservancy project construction with a filtering function comprises: a water suction pipe 1, a spiral separator 2 is connected to the upper end of the water suction pipe 1, the spiral separator 2 is located on the upper part of a sedimentation tank 3, a water supply pipe 4 is connected to the upper part of the spiral separator 2, the water supply pipe 4 is connected to a vertical vacuum pump 5, the vertical vacuum pump 5 is connected to a water outlet pipe 6, the vertical vacuum pump 5 is located on the top of the sedimentation tank 3, and the water suction pipe 1, the spiral separator 2, the sedimentation tank 3, the water supply pipe 4, the vertical vacuum pump 5 and the water outlet pipe 6 are sealed and connected.
[0025] The positions of the water suction pipe 1, the spiral separator 2, the sedimentation box 3, the water supply pipe 4, the vertical vacuum pump 5 and the water outlet pipe 6 are arranged compactly and orderly. The entire device only needs to control the switch of the vertical vacuum pump 5 to achieve the function of draining water and collecting sewage. The device has a simple structure and is easy to operate. The advantage of the sealing setting of the entire device is to prevent gas from penetrating into the interior of the device and affecting the water pumping efficiency of the equipment.
[0026] In a further embodiment, the spiral separator 2 includes: an outer shell 7, an inner shell 8, a cover plate 10 and a spiral scraper 9. The spiral scraper 9 is located between the outer shell 7 and the inner shell 8. The cover plate 10 is sealed and connected to the top of the outer shell 7. The spiral scraper 9 is fixedly connected to the inner wall of the outer shell 7, and the spiral scraper 9 is slidably connected to the inner shell 8.
[0027] The spiral scraper 9 can scrape out impurities attached to the annular filter 12 when the inner shell 8 rotates, and transport the impurities to the inside of the sedimentation box 3 for collection. The cover plate 10 is sealed with the top of the outer shell 7 to improve the sealing of the entire device and ensure the stable operation of the entire device.
[0028] In a further embodiment, the outer shell 7 is a conical cylinder, the bottom of the outer shell 7 is fixedly connected to the sedimentation tank 3 and the interior of the outer shell 7 is connected to the interior of the sedimentation tank 3, the connection between the outer shell 7 and the water suction pipe 1 is located below the spiral scraper 9, the water supply pipe 4 passes through the cover plate 10 and is fixedly connected to the cover plate 10, and the connection between the water supply pipe 4 and the cover plate 10 is located at the center of the cover plate 10.
[0029] The shape of the outer shell 7 can increase the impact force of the bottom water flow and can carry away a large amount of debris into the sedimentation box 3. The connection between the outer shell 7 and the suction pipe 1 is located below the spiral scraper 9, which can reduce the movement space of the water flow entering from the suction pipe 1, increase the static pressure of the water flow, and provide greater driving force for the rotation of the inner shell 8.
[0030] In a further embodiment, the inner shell 8 is a conical box and has the same shape as the outer shell 7. A sealed bearing 11 is arranged at the upper center position of the inner shell 8. One end of the water supply pipe 4 passes through the sealed bearing 11 and extends into the interior of the inner shell 8 and is rotatably connected to the inner shell 8. A plurality of annular filters 12 are arranged on the side of the inner shell 8, and the annular filters 12 are fixedly connected to the inner shell 8.
[0031] The inner shell 8 and the outer shell 7 have the same shape, so that any point on the outer side of the inner shell 8 is at an equal distance from a corresponding point on the inner side of the outer shell 7. The sealed bearing 11 reduces the friction between the water supply pipe 4 and the inner shell 8, and reduces the resistance when the inner shell 8 rotates. The annular filter 12 can filter out impurities in the water and allow the filtered water to flow into the inner shell 8, preventing impurities from damaging the vertical vacuum pump 5.
[0032] In a further embodiment, a plurality of baffles 13 are evenly arranged on the side of the inner shell 8, the connection between the outer shell 7 and the suction pipe 1 and the baffle 13 are located on the same horizontal plane, and the angle between the section at the connection between the inner shell 8 and the baffle 13 and the baffle 13 is between 75° and 45°.
[0033] The setting of the baffle 13 can convert the impact force of the water in the suction pipe 1 on the baffle 13 into the kinetic energy of the inner shell 8, and can make the inner shell 8 rotate automatically. The setting of the connection between the outer shell 7 and the suction pipe 1 and the baffle 13 being located on the same horizontal plane can make the baffle 13 better contact with the water flow rushing out of the suction pipe 1. The angle setting between the cross-section of the connection between the inner shell 8 and the baffle 13 and the baffle 13 improves the energy conversion efficiency.
[0034] In a further embodiment, a sewage pipe 14 is connected to one side of the sedimentation tank 3, and the sewage pipe 14 is connected to a valve 15. An observation window 16 is provided on one side of the sedimentation tank 3. The observation window 16 is made of glass or acrylic. The observation window 16 is located below the spiral separator 2, and the observation window 16 is sealed and connected to the sedimentation tank 3.
[0035] The setting of the observation window 16 can directly observe the accumulation of debris in the sedimentation box 3. When there is a lot of debris, the valve 15 can be opened to discharge it through the sewage pipe 14. The area below the spiral separator 2 is the main area for debris accumulation. The observation window 16 is set below the spiral separator 2 to better observe the accumulation of debris in the sedimentation box 3.
[0036] During use, place the suction pipe into the ditch that needs to be drained, start the vertical vacuum pump, and water enters the spiral separator through the suction pipe. The dirty water hits the baffle on the inner shell. The inner shell rotates with the water supply pipe as the center. The dirty water enters the inner shell through the annular filter screen, and the debris is blocked on the outside by the annular filter screen. When the inner shell rotates, the spiral scraper transports the impurities on the filter screen to the bottom of the spiral separator, and enters the sedimentation box through the connection between the spiral separator and the sedimentation box. The impurities are statically settled to the bottom of the sedimentation box and accumulated. The accumulation of debris in the sedimentation box can be checked through the observation window, and the valve can be opened to discharge the debris through the sewage pipe.
[0037] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0038] 1. The spiral separator can filter out impurities and collect them automatically, and does not consume electricity during operation, thus improving energy utilization.
[0039] 2. The setting of the sedimentation box can store a large amount of impurities, which can ensure the long-term use of the device and improve work efficiency.
