Description

Technical Field

[0001] The utility model relates to the technical field of anti-sedimentation of aeration tanks, in particular to an anti-sedimentation device for aeration tanks. Background Art

[0002] According to the investigation and analysis, in the conventional wastewater treatment process design, when designing the biochemical pool aeration tank, the aeration plate needs to be fixed on the pipeline, and the pipeline needs to be fixed on the ABS bracket or stainless steel frame. This results in the aeration plate being at least 30 cm away from the bottom of the pool. This design defect directly leads to the position below the aeration plate. There is no aeration stirring effect. Even if there is, it is a smaller disturbance in the radiation range near the aeration plate. In the long run, it will inevitably lead to sludge deposition below the aeration plate, forming an anaerobic environment, affecting the effluent phosphorus index.

[0003] At the same time, when the pool is being repaired and inspected, the bottom mud formed by long-term sedimentation also affects the maintenance operation. There is also a risk of toxic and harmful gas release affecting the health of maintenance personnel. This new anti-sedimentation device just solves this technical problem.

[0004] In addition, because the anti-sedimentation device is an integrated pipeline, when a single section of the pipeline has a problem, the entire section of the pipeline needs to be replaced for maintenance, which is not only cumbersome to operate, but also wastes other pipelines that have not had problems. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example 1

[0033] Reference Figure 1-6 , which is the first embodiment of the utility model, provides an aeration tank anti-sedimentation device, including an air supply system 1, an aeration system 11 is arranged on the air supply system 1, an anti-sedimentation pipe 2 is arranged at the lower side of the air supply system 1, the anti-sedimentation structure is composed of a plurality of anti-sedimentation pipes 2, an exhaust pipe 21 is fixedly connected to the lower side of the anti-sedimentation pipe 2, and a rotating chute 22 is arranged at the upper side of the exhaust pipe 21;

[0034] It also includes an anti-settling structure arranged in the anti-settling pipe 2;

[0035] The anti-settling structure includes a fan blade axis 31 arranged in the anti-settling tube 2, a rotating shaft 32 fixed on the fan blade axis 31, so that the entire column is rotatably connected in the anti-settling tube 2, a fan blade 33 slidably connected and installed on the fan blade axis 31, an extension column 34 fixed on the lower side of the rotating shaft 32, a limiting ring 35 fixed on the extension column 34, and a vertical slide groove 36 opened on the extension column 34.

[0036] The extension column 34 is movably connected with a liquid blocking plug 37 , which is slidably connected to the extension column 34 through a vertical slide groove 36 , and the diameter of the liquid blocking plug 37 fits the inner diameter of the exhaust pipe 21 , and the limiting ring 35 is used to limit the liquid blocking plug 37 , and the lower side of the extension column 34 is fixedly connected with an annular sleeve 38 .

[0037] The rotating shaft 32 is rotatably connected to the inner side of the anti-settling pipe 2, the extension column 34 is arranged in the exhaust pipe 21, the rotating shaft 32 passes through the fan blade axis 31, the upper end of the rotating shaft 32 is rotatably connected to the upper inner wall of the anti-settling pipe 2, and the lower end of the rotating shaft 32 extends to the outside of the exhaust pipe 21 through the extension column 34. The annular slider 39 on the annular sleeve 38 fixedly connected to the lower side of the extension column 34 and the rotating slide groove 22 are slidably connected in the exhaust pipe 21.

[0038] An annular slider 39 is fixedly connected to the upper side of the annular sleeve 38 , and an air outlet pipe 310 is provided on the annular sleeve 38 .

[0039] The annular sleeve 38 is rotatably connected to the lower side of the exhaust pipe 21 , and the air outlet pipes 310 are evenly arranged on the annular sleeve 38 . There are six air outlet pipes 310 in total, which are evenly distributed on the annular sleeve 38 at equal angles.

[0040] A solenoid valve 311 is provided on one side of the air outlet pipe 310 . The number of the solenoid valves 311 corresponds to the number of the air outlet pipes 310 . The solenoid valves 311 can be opened at intervals or simultaneously by setting a program. A filter screen 312 is fixedly connected to the inner side of the air outlet pipe 310 .

[0041] An air guide plate 23 is fixedly connected to the inner side of the anti-settling pipe 2 . The air guide plate 23 fits the inside of the anti-settling pipe 2 . An air guide port 24 is provided on the air guide plate 23 . A quick-release structure is provided on the upper side of the anti-settling pipe 2 .

[0042] The solenoid valve 311 is fixedly connected to the inner side of the annular sleeve 38 , and the opening position of the air guide port 24 is aligned with the fan blade 33 .

[0043] During use, when the air supply system 1 and the aeration system 11 start to work, the gas will also be connected to the anti-sedimentation structure. First, the gas will enter the anti-sedimentation pipe 2. Before the gas enters, it will be blocked by the air guide plate 23. The opening of the air guide port 24 can guide the gas to pass through it. Because the position of the air guide port 24 corresponds to the position of the fan blade 33, the gas will drive the fan blade 33 to rotate after entering. Because the fan blade 33 is connected to the fan blade axis 31, and the fan blade axis 31 and the rotating shaft 32 are fixedly connected, the rotating shaft 32 will be driven to rotate. The rotating shaft 32 is fixedly connected to the extension column 34 and the annular sleeve 38, so the lower part of the extension column 34 and the annular sleeve 38 will be driven to rotate, so that the outlet pipe 310 installed on the annular sleeve 38 can rotate to discharge gas, blow away the bottom sludge, and clean the surroundings;

[0044] During this process, when the gas pressure is large enough, the liquid blocking plug 37 can be pressed down to open the space between the annular sleeve 38 and the exhaust pipe 21, and the solenoid valve 311 can control the number of openings of the outlet pipe 310, or open it periodically to cope with various amounts of sludge. When the amount of sludge is too much and the accumulation time is too long, several solenoid valves 311 can be closed first to increase the outlet air pressure of the outlet pipe 310. When the accumulated sludge is blown to a smaller state, the outlet pipe 310 is periodically opened for blowing, and the annular sleeve 38 is always rotatably connected to the exhaust pipe 21 through the annular slider 39 and the rotating slide groove 22.

[0045] Example 2

[0046] Reference Figure 1-6 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the quick-release structure includes a mounting sleeve 41 movably connected to the outside of the anti-settling pipe 2, a fixing plate 42 fixed in the mounting sleeve 41, a first threaded groove 43 arranged on the mounting sleeve 41, and a screw 44 arranged on the mounting sleeve 41.

[0047] The anti-settling pipe 2 is inserted into the inner side of the mounting sleeve 41. The mounting sleeve 41 produces an annular groove by cooperating with the fixing plate 42. The shape and diameter of the annular groove are adapted to the anti-settling pipe 2, so that the anti-settling pipe 2 can be inserted into the annular groove. A second thread groove 45 is provided on the anti-settling pipe 2. The position of the second thread groove 45 is the same as the position of the first thread groove 43 on the mounting sleeve 41, and they can cooperate with each other. In addition, the first thread groove 43 is also provided on the fixing plate 42.

[0048] During use, the anti-settling pipe 2 is inserted into the annular groove formed by the mounting sleeve 41 and the fixing plate 42, wherein the second threaded groove 45 of the anti-settling pipe 2 needs to be aligned with the first threaded groove 43 of the mounting sleeve 41 and the fixing plate 42, and then the three are fixed with screws 44. Two first threaded grooves 43 are provided on a mounting sleeve 41 for fixing the anti-settling pipes 2 at both ends. When a problem occurs with the anti-settling pipe 2 at one end, the screws 44 on the mounting sleeves 41 at both ends of the anti-settling pipe 2 can be removed so that the anti-settling pipe 2 at this end can be removed, thereby facilitating subsequent maintenance and replacement, and avoiding the problem of requiring entire pipe to be replaced due to damage or failure of a single pipe.

[0049] The remaining structures are the same as those of Example 1.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
