DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] In order to solve the technical problem in the prior art that the inner wall of the water distribution connecting hose is very easy to adhere to impurities such as dirt, which easily leads to the reduction of the effective aperture in the pipe and blockage, the utility model provides a water distribution device, which uses the cleaning brush to clean the inner wall of the water distribution hose, thereby achieving the purpose of clearing the water distribution hose, and fundamentally solving the problem of poor water distribution effect when the effective aperture of the water distribution hose becomes smaller.

[0034] See also Figure 1 , Figure 1 This is a structural diagram of a water distribution device in one embodiment of the present utility model.

[0035] The utility model provides a water distribution device, including a water distribution box 1 and a water distribution assembly, wherein the water distribution box 1 is used to be installed above the pool 200; the water distribution assembly includes a fixed guide rope 2, a water distribution hose 3, a movable pull rope 4 and a cleaning brush 5, the upper end of the fixed guide rope 2 is passed through the water distribution box 1, and the lower end of the fixed guide rope 2 is fixed to the bottom of the pool 200, the water distribution hose 3 is sleeved on the outer periphery of the fixed guide rope 2, the upper end of the water distribution hose 3 is connected to the water distribution box 1, the cleaning brush 5 is sleeved on the outer periphery of the fixed guide rope 2, one end of the movable pull rope 4 is connected to the cleaning brush 5, and the other end of the movable pull rope 4 passes through the water distribution hose 3 and extends into the water distribution box 1.

[0036] In this embodiment, the water distribution box 1 is installed above the water pool 200, the upper end of the fixed guide rope 2 is passed through the water distribution box 1, and the lower end of the fixed guide rope 2 is fixed to the bottom of the water pool 200. The water distribution hose 3 is sleeved on the outer periphery of the fixed guide rope 2, and the upper end of the water distribution hose 3 is connected to the water distribution box 1. The cleaning brush 5 is slidably installed on the fixed guide rope 2, and one end of the movable cable 4 is connected to the cleaning brush 5. The other end of the movable cable 4 passes through the water distribution hose 3 and extends into the water distribution box 1. When the inner diameter of the water distribution hose 3 is reduced or blocked after being used for a period of time, the cleaning brush 5 can be driven by the movable cable 4 to reciprocate in the water distribution hose 3, and the inner wall of the water distribution hose 3 can be brushed by the cleaning brush 5, thereby achieving the purpose of clearing the water distribution hose 3, fundamentally solving the problem of poor water distribution effect after the effective aperture of the water distribution hose 3 becomes smaller.

[0037] The water distribution hose 3 is made of a flexible material. In order to position the water distribution hose 3, a straight fixed guide rope 2 can be set between the water distribution tank 1 and the bottom of the pool 200. The water distribution hose 3 is sleeved on the outer periphery of the fixed guide rope 2. The water distribution hose 3 is positioned by the fixed guide rope 2 to prevent it from swinging. At the same time, the fixed guide rope 2 can also guide the cleaning brush 5, allowing it to move along the length direction of the fixed guide rope 2.

[0038] In this embodiment, the water distribution tank 1 is made of stainless steel and can be in a circular, square or other shape. The upper end is open, and the side walls and bottom are closed. Fixed legs of a certain height are provided at the bottom of the water distribution tank 1 and are placed at an appropriate position on the top of the pool 200 for evenly distributing the water entering the pool 200.

[0039] In one embodiment, see Figures 2 to 5 The water distribution tank 1 is provided with a water inlet area 11, a water distribution area 12 and a water distribution area 13 which are arranged in sequence along the sewage flow direction. The water distribution tank 1 is also provided with a water inlet connected to the water inlet area 11, wherein there are multiple water distribution areas 13, and there are multiple water distribution components. The multiple water distribution components correspond one to one to the multiple water distribution areas 13, and the water distribution area 13 is connected to the water distribution hose 3.

[0040] In this embodiment, the function of the water distribution tank 1 is to evenly distribute sewage. Therefore, the water distribution tank 1 can be divided into a water inlet area 11, a water distribution area 12 and a water distribution area 13 according to actual conditions. The water inlet area 11 is used to connect to an external pipeline, and the water distribution area 12 is used to evenly distribute water to the water distribution area 13. The lower ends of multiple water distribution hoses 3 are evenly distributed at the bottom of the pool 200, and multiple water distribution areas 13 transport sewage evenly to the bottom of the pool 200 through the water distribution hoses 3. During specific use, the sewage first enters the water inlet area 11. When the water inlet area 11 is full, the sewage overflows into the water distribution area 12. When the water distribution area 12 is full, it overflows into multiple water distribution areas 13 at the same time, thereby achieving the purpose of water distribution.

[0041] In one embodiment, see Figure 3 The multiple water distribution areas 13 are divided into two groups, and the two groups of water distribution areas 13 are respectively arranged on the opposite sides of the water distribution area 12.

[0042] In this embodiment, the water inlet area 11 is located at one end of the water distribution tank 1, the water distribution area 12 is located in the middle area of the water distribution tank 1, and the multiple water distribution areas 13 are divided into two groups. The two groups of water distribution areas 13 are respectively arranged on the opposite sides of the water distribution area 12, that is, the water distribution areas 13 are located on both sides of the water distribution tank 1. By reasonably allocating the space in the water distribution tank 1, a better water distribution effect is achieved.

[0043] In one embodiment, see Figures 2 to 5 A water distribution plate 14 is provided between the water inlet area 11 and the water distribution area 12, a water outlet weir plate 15 is provided between the water distribution area 12 and the water distribution area 13, and a partition plate 16 is provided between two adjacent water distribution areas 13. The height of the water distribution tank 1, the height of the water distribution plate 14 and the height of the water outlet weir plate 15 decrease in sequence, and the height of the partition plate 16 is greater than the height of the water outlet weir plate 15.

[0044] In this embodiment, the water inlet area 11 and the water distribution area 12 are separated by a water distribution plate 14, the water distribution area 12 and the water distribution area 13 are separated by an outlet weir plate 15, the water inlet area 11 and the water distribution area 13 are separated by a water retaining plate 17, and each water distribution area 13 is separated by a partition plate 16. The top elevation of the water distribution plate 14 is 0.3~0.5m less than the top surface of the water distribution tank 1 and 0.15~0.3m greater than the top of the outlet weir plate 15. The top elevations of the water retaining plate 17 and the partition plate 16 are consistent with the top surface elevation of the water distribution tank 1, and the outlet weir plates 15 corresponding to each water distribution area 13 have the same number, size and elevation of the outlets.

[0045] In one embodiment, see Figures 7 and 8 The lower end of the water distribution hose 3 is gradually expanded.

[0046] In this embodiment, the lower end of the water distribution hose 3 is 0.3m~0.6m away from the bottom of the pool 200. When the water distribution hose 3 is in normal use, the cleaning brush 5 is located at the lower end of the fixed guide rope 2, that is, the cleaning brush 5 extends out of the water distribution hose 3, so that the cleaning brush 5 can avoid interfering with the use of the water distribution hose 3. When the water distribution hose 3 needs to be cleared, the cleaning brush 5 needs to enter the water distribution hose 3. In order to achieve a better brushing effect, the diameter of the cleaning brush 5 (including soft bristles) is usually slightly larger than the inner diameter of the water distribution hose 3. In order to avoid the cleaning brush 5 being stuck at the lower end of the water distribution hose 3, the lower end of the water distribution hose 3 is gradually expanded to form a trumpet-shaped structure. This arrangement allows the cleaning brush 5 to smoothly enter the water distribution hose 3.

[0047] In one embodiment, see Figure 2 and Figure 7 , a through hole is provided at the bottom of the water distribution box 1; the water distribution device also includes a water distribution pipe joint 18, the water distribution pipe joint 18 is installed in the through hole, and the upper end of the water distribution hose 3 is detachably connected to the water distribution pipe joint 18.

[0048] In this embodiment, the diameter of the water distribution hose 3 is De40~De63. The water distribution hose 3 can be made of a material that is both flexible and corrosion-resistant, such as PE. It is used to distribute the water flow distributed by the water distribution tank 1 to the bottom of the pool in a fixed and even manner, and to achieve a good mud-water mixing effect. The upper end of the water distribution hose 3 is provided with a joint, which is detachably connected to the water distribution pipe joint 18. The lower end outlet of the water distribution hose 3 is downward and perpendicular to the bottom of the pool, 0.3~0.6m from the bottom of the pool. The water distribution hose 3 is set to a detachable connection to facilitate the maintenance of the water distribution hose 3 in the later stage.

[0049] The fixed guide rope 2 passes through the water distribution pipe joint 18 and extends into the water distribution area 13 and is connected to the side wall of the water distribution area 13 .

[0050] Furthermore, there is no limitation on the connection method between the joint and the water distribution pipe joint 18, and it can be one of threaded connection, pipe clamp connection, and flange connection.

[0051] In one embodiment, the upper end of the fixed guide rope 2 is detachably connected to the water distribution box 1 .

[0052] In this embodiment, since the water distribution hose 3 is detachably connected to the water distribution box 1, in order to facilitate the disassembly and installation of the water distribution hose 3, the upper end of the fixed guide rope 2 is also detachably connected to the water distribution box 1 to avoid interference.

[0053] In one embodiment, see Figures 4 to 6 The side wall of the water distribution area 13 is provided with a first fixed ring 131, and the upper end of the fixed guide rope 2 is provided with a first circular hook 21. The first circular hook 21 is hung on the first fixed ring 131, and the outer diameter of the first circular hook 21 is smaller than the inner diameter of the water distribution hose 3.

[0054] In this embodiment, the first fixing ring 131 is provided on one side of the partition plate 16, and a first circular hook 21 is provided at the upper end of the fixing guide rope 2. The first circular hook 21 can be hung on the first fixing ring 131 or removed from the first fixing ring 131, which is simple to operate and facilitates the disassembly of the fixing guide rope 2.

[0055] Furthermore, the side wall of the water distribution area 13 is provided with a first limiting plate 132, and the first limiting plate 132 is arranged on the same side as the first fixing ring 131 and is located below the first fixing ring 131. The first limiting plate 132 is provided with a first limiting hole, and the diameter of the first limiting hole is adapted to the diameter of the fixed guide rope 2. The diameter of the first limiting hole is smaller than the diameter of the first ring hook 21, so that the first ring hook 21 cannot pass through the first limiting hole directly, and the first ring hook 21 needs to be manually held to bypass the first limiting hole.

[0056] Furthermore, a water distribution fixture is provided at the bottom of the pool 200 corresponding to the fixed guide rope 2. The water distribution fixture includes a fixing plate 23 and a triangular ring 24. The fixing plate 23 is fixed to the bottom of the pool 200 by anchoring or welding. The triangular ring 24 is located on the upper side of the fixing plate 23 and is fixedly connected thereto. A movable ring 22 is provided at the lower end of the fixed guide rope 2. The movable ring 22 is connected to the triangular ring 24, thereby achieving the purpose of fixing the lower end of the fixed guide rope 2 to the bottom of the pool 200. The movable ring 22 and the triangular ring 24 are detachably connected.

[0057] In one embodiment, see Figures 4 to 6 The side wall of the water distribution area 13 is provided with a second fixed ring 133, and the upper end of the movable rope 4 is provided with a second circular hook 41. The second circular hook 41 is hung on the second fixed ring 133, and the outer diameter of the second circular hook 41 is smaller than the inner diameter of the water distribution hose 3.

[0058] In this embodiment, the second fixing ring 133 is provided on one side of the partition plate 16, and a second circular hook 41 is provided at the upper end of the movable cable 4. The second circular hook 41 can be hung on the second fixing ring 133 or removed from the second fixing ring 133, which is simple to operate and facilitates the disassembly of the movable cable 4.

[0059] Furthermore, the side wall of the water distribution area 13 is provided with a second limiting plate 134, which is arranged on the same side as the second fixing ring 133 and is located below the second fixing ring 133. The second limiting plate 134 is provided with a second limiting hole, and the diameter of the second limiting hole is adapted to the diameter of the movable rope 4. The diameter of the second limiting hole is smaller than the diameter of the second ring hook 41, so that the second ring hook 41 cannot pass directly through the second limiting hole, and the second ring hook 41 needs to be manually held to bypass the second limiting hole.

[0060] In this embodiment, the cleaning brush 5 is connected to the movable cable 4 through a flexible joint. The cleaning brush 5 is a hard round tube with soft bristles evenly fixed on the outer surface. It is made of corrosion-resistant plastic material and has a length of 0.1~0.2m. The outer diameter of the hard round tube of the cleaning brush 5 is smaller than the inner diameter of the water distribution hose 3 and its inner hole diameter is larger than the outer diameter of the movable cable 4. The diameter of the outer edge of the cleaning brush 5 (including soft bristles) is slightly larger than the inner diameter of the water distribution hose 3. The upper end of the cleaning brush 5 is located at the lower end of the water distribution hose 3 and is 0.1~0.3m away from the outlet of the water distribution hose 3. When the movable cable 4 is lifted or pressed down, the cleaning brush 5 can be removed from the water distribution hose 3. The water distribution hose 3 goes in and out, thereby effectively cleaning the inner wall of the water distribution hose 3. The flexible joint is in the shape of a short round tube, consisting of a round tube with a length of 20~30mm and a nut with a threaded external thread. The round tube is fixed on the movable cable 4 near the two ends of the cleaning brush 5, and its outer diameter is smaller than the inner diameter of the cleaning brush 5. The nut is threadedly connected to the round tube, and the outer diameter of the nut is larger than the outer diameter of the round tube. When the nut is tightened, the position of the cleaning brush 5 is fixed, and the cleaning brush 5 cannot be detached from the movable cable 4. When the cleaning brush 5 needs to be taken out, the cleaning brush 5 can be conveniently taken out after loosening and removing the nut.

[0061] In one embodiment, the water distribution device also includes a connecting rope, one end of which is provided with a ring, so that when the water distribution hose 3 is disassembled, the first ring hook 21 and the second ring hook 41 are hung on the ring, the length of the connecting rope is more than 0.2m greater than the length of the water distribution hose 3, and the outer diameter of the ring is smaller than the inner diameter of the water distribution hose 3.

[0062] In this embodiment, in order to facilitate the replacement of the water distribution hose 3, a connecting rope is also provided. The connecting rope can be detachably connected to the first ring hook 21 and the second ring hook 41. The length of the fixed guide rope 2 and the movable pull rope 4 can be extended through the connecting rope, thereby facilitating the replacement of the water distribution hose 3.

[0063] In order to better understand the present invention, the following Figures 1 to 8 The technical solution of the utility model is described in detail:

[0064] The water flow to be treated enters the water inlet area 11 through a pipe connected to the water inlet, forms a stable flow state in the water inlet area 11, and then overflows and is evenly distributed into the water distribution area 12 through the water distribution plate 14. The water flow in the water distribution area 12 flows out from the outlet weir plate 15 and is evenly distributed to each of the water distribution areas 13. Under the action of gravity, the water flows from the water distribution area 13 into each of the water distribution hoses 3, and is continuously and evenly distributed to the bottom of the pool 200 through the evenly distributed water distribution hoses 3. The mud and water are homogeneously mixed in the process of water flow from bottom to top.

[0065] After distributing water for a period of time, when dirt adheres to the inner wall of the water distribution hose 3, causing the effective aperture to be greatly reduced or the water distribution hose 3 to be blocked, the second circular ring hook 41 can be removed from the partition plate 16, and the movable cable 4 can be lifted to allow the cleaning brush 5 to enter the water distribution hose 3, and then the movable cable 4 can be pulled up or pressed down to make the cleaning brush 5 brush up and down repeatedly in the water distribution hose 3 to make the dirt or debris on the pipe wall fall off from the inner wall of the pipe. When the cleaning is completed, the second circular ring hook 41 is hung on the second fixed ring 133. At this time, the cleaning brush 5 is reset under the water distribution hose 3, and the dirt on the water distribution hose 3 is discharged from the bottom outlet of the water distribution hose 3 into the pool 200. When large particles of impurities enter the water distribution hose 3, the movable cable 4 can be pulled up to remove the large particles of impurities from the upper end of the water distribution hose 3.

[0066] Affected by factors such as external water inlet conditions and treatment effects, when the water distribution hose 3 needs to be taken out and cleaned, repaired or replaced, the water outlet weir plate 15 corresponding to the water distribution hose 3 can be sealed with waterproof tape, so that water cannot enter the water distribution area 13 corresponding to the water distribution hose 3, and the water distribution hose 3 is disassembled from the bottom of the water distribution tank 1, and the first ring hook 21 and the second ring hook 41 are taken out from the partition plate 16 and passed through the water distribution area 13, so that the fixed guide rope 2 and the movable pull rope 4 are taken out from the bottom of the water distribution tank 1, and the connecting rope is connected to the fixed guide rope 2 and the movable pull rope 4. The fixed guide rope 2 and the movable pull rope 4 are connected, and the water distribution hose 3 is taken out from the hole at the top of the water pool 200. The water distribution hose 3 is then cleaned, repaired or replaced. After completing the above steps, the fixed guide rope 2 and the movable pull rope 4 are inserted into the water distribution hose 3. The circular hooks of the fixed guide rope and the movable pull rope 4 are inserted from bottom to top along the through holes and the limit holes of the water distribution area 13 and hung on the water distribution plate to reset. The water distribution hose 3 is connected to the bottom of the water distribution tank 1. The water distribution hose 3 is reset to complete the installation. The waterproof tape on the water outlet weir plate 15 is untied, and the water distribution hose 3 is restored to normal use.

[0067] The present application realizes the online clearing of the water distribution hose 3. The clearing steps are simple and the effect is obvious, thereby solving the problem that the water distribution and mud water mixing effect gradually deteriorates after the aperture of the water distribution hose 3 becomes smaller or blocked, and provides stable conditions for the efficient reaction of upflow hydrolysis acidification, UASB and other water pools 200.

[0068] The present application realizes the replacement and resetting of the water distribution hose 3 under the condition of continuous operation of the water pool 200. The replacement cost is low and the replacement process is safe and reliable. The specifications of the water distribution hose 3 used can be flexibly adjusted according to the changes in water quality and water quantity and the treatment effect, so that the sludge is not easily lost under the condition of sufficient mixing of mud and water, thereby improving the operational adaptability of the upflow hydrolysis acidification, UASB and other water pools 200.

[0069] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
