Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a water distribution device for an anaerobic tower. Background Technology

[0002] Anaerobic biological treatment of wastewater is an important technology in environmental engineering and energy engineering. It is a treatment method that uses the degradation of organic matter in wastewater by anaerobic microorganisms under anaerobic conditions to purify the wastewater.

[0003] A search revealed a Chinese patent with authorization announcement number CN219449470U, which discloses a water distribution device for an anaerobic tower in wastewater treatment. The device includes an anaerobic tower and a water distribution assembly disposed inside the anaerobic tower.

[0016] By adopting the above technical solution, the length of the installation port must be greater than the length of the telescopic rod, which facilitates the disassembly, replacement and maintenance of the filter screen.

[0017] Preferably, a discharge port is provided on one side of the outer wall of the water storage tank, and a discharge plate is sealed and hinged inside the discharge port. A first pull block is fixedly installed on one side of the outer wall of the discharge plate.

[0018] By adopting the above technical solution, the discharge plate can be opened by pulling the first pull block. Then, the bucket lid can be opened, and the sludge and other impurities can be cleaned from the discharge port into the collection box by the external shovel, thus completing the cleaning.

[0019] Preferably, a support plate is fixedly installed on one side of the outer wall of the water storage tank, and a collection box is installed on the top outer wall of the support plate by bolts. The collection box is located below the discharge port.

[0020] By adopting the above technical solution and setting up collection boxes, sludge and other impurities can be collected.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. In this application, a filter screen is used in conjunction with other components. The water flow impacts the filter screen, causing it to move downwards and compress the telescopic rod and spring. This allows the filter screen to move up and down repeatedly, preventing sludge from clogging it. The filter screen blocks some of the sludge and other impurities, preventing excessive sludge from clogging multiple guide pipes and annular pipes. Therefore, clogging will not occur even after long-term use, improving water distribution effect and efficiency.

[0030] This application discloses a water distribution device for an anaerobic tower.

[0031] Reference Figure 2-4 A water distribution device for an anaerobic tower includes an anaerobic tower 1, a support 2 fixedly installed inside the anaerobic tower 1, a water storage tank 3 fixedly installed on the support 2, a water distribution mechanism 4 disposed outside the water storage tank 3, a filtration mechanism and a discharge mechanism disposed inside the water storage tank 3, an inlet pipe 8 connected to external sewage on one side above the water storage tank 3, and a tank cover 7 hinged to the water storage tank 3.

[0032] The filtration mechanism includes a filter screen 11 that is slidably installed inside the water storage tank 3, two telescopic rods 20 that are symmetrically fixedly installed on the bottom outer wall of the filter screen 11, a telescopic spring 21 sleeved on the two telescopic rods 20, a pad 22 that is fixedly installed at one bottom end of each of the two telescopic rods 20, a connecting plate 23 that is fixedly installed on the bottom outer wall of each of the two pads 22, a threaded hole 24 opened on the two connecting plates 23, and a fixing bolt 25 screwed into the threaded hole 24.

[0033] In use, the water flow impacts the filter screen 11, causing it to move downwards and compress the telescopic rod 20 and the telescopic spring 21. This allows the filter screen 11 to move up and down repeatedly, preventing sludge from clogging it. The filter screen 11 blocks some sludge and other impurities. By rotating the fixing bolt 25, the fixing of the connecting plate 23 can be released, thereby releasing the fixing of the filter screen 11.

[0034] Reference Figure 1 The water distribution structure consists of multiple guide pipes 5 and multiple ring pipes 6. The multiple guide pipes 5 are all inclined and one end is fixedly connected to the water storage tank 3. The multiple ring pipes 6 are all connected to the multiple guide pipes 5 in a through manner.

[0035] The sewage in the water storage tank 3 is guided by multiple guide pipes 5, and the sewage flows into the anaerobic tower 1 through multiple ring pipes 6, thus playing the role of water distribution.

[0036] Reference Figure 2 and Figure 3 The discharge mechanism includes an installation port 9 on one side of the outer wall of the water storage tank 3, a sealing and hinged installation plate 10 in the installation port 9, a second pull block 17 fixedly installed on one side of the outer wall of the installation plate 10, a discharge port 12 on one side of the outer wall of the water storage tank 3, a discharge plate 13 sealed and hinged in the discharge port 12, a first pull block 14 fixedly installed on one side of the outer wall of the discharge plate 13, a support plate 15 fixedly installed on one side of the outer wall of the water storage tank 3, and a collection box 16 bolted to the support plate 15.

[0037] By pulling the first pull block 14, the discharge plate 13 can be opened. Then, the bucket lid 7 can be opened, and the sludge and other impurities can be cleaned from the discharge port 12 into the collection box 16 by the external shovel, thus completing the cleaning.

[0038] Reference Figure 3 A positioning screw 18 is fixedly installed on one side of the outer wall of the water storage tank 3. A positioning plate 19 for positioning and installing the mounting plate 10 is screwed onto the positioning screw 18. The mounting port 9 is parallel to the position of the fixing bolt 25, and the length of the mounting port 9 is greater than the length of the telescopic rod 20.

[0039] By rotating the positioning plate 19, the restriction on the mounting plate 10 can be released. At this time, the second pull block 17 can be pulled to open the mounting plate 10, and the filter screen 11 can be disassembled.

[0040] The implementation principle of the water distribution device of the anaerobic tower in this application embodiment is as follows: During use, the water inlet pipe 8 is connected to the external sewage pipe, so that the sewage flows into the water storage tank 3 and is impacted by the water flow filter screen 11, causing the filter screen 11 to move downward and compress the telescopic rod 20 and the telescopic spring 21, so that the filter screen 11 can move up and down repeatedly, avoiding sludge clogging the filter screen 11. Thus, the filter screen 11 blocks some sludge and other impurities, preventing excessive sludge from clogging multiple guide pipes 5 and multiple annular pipes 6. Therefore, no clogging will occur even after long-term use, improving the water distribution effect and efficiency.

[0041] When it is necessary to clean the sludge and other impurities on the filter screen 11, the discharge plate 13 can be opened by pulling the first pull block 14. Then, the bucket cover 7 can be opened, and the sludge and other impurities can be cleaned from the discharge port 12 into the collection box 16 by the external scraper, thus completing the cleaning.
