Abstract
Description
Technical Field
[0001] This utility model relates to the field of rural sewage treatment technology, and more specifically, to an aeration device for rural domestic sewage treatment. Background Technology
[0002] In the process of rural sewage treatment, aeration is an extremely important step. Its main function is to increase the dissolved oxygen in the reaction tank by stirring or other means, thereby improving the activity of aerobic microorganisms and increasing the operating efficiency of the biochemical system. Aeration devices are generally installed at the bottom of the treatment tank and consist of aeration discs, support pipes, air pipes, etc. Air is discharged from the micropores on the surface of the aeration discs, generating a large number of bubbles, increasing the contact area between oxygen and water, and thus increasing the dissolved oxygen.
[0003] Most rural domestic sewage treatment needs to adhere to the principles of high efficiency, economy, energy saving, and ease of use. However, most current sewage treatment aeration devices are continuous aeration devices, which cannot control and adjust the aeration rhythm and mode, leading to over-aeration in the tank and consequently, poor aeration effect. In order to solve the problem of over-aeration caused by continuous aeration and thus poor aeration effect, we propose an aeration device for rural domestic sewage treatment. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 6 As shown, this utility model provides an aeration device for rural domestic sewage treatment, comprising:
[0029] The regulating chamber 1 has an air inlet chamber 2 fixedly connected to it, and an annular sealing plate 3 fixedly connected inside the regulating chamber 1.
[0030] The regulating mechanism is located inside the regulating chamber 1;
[0031] The regulating mechanism includes a rotating shaft 4, one end of which is rotatably connected to the inner wall of the air inlet chamber 2. The rotating shaft 4 is rotatably inserted inside the regulating chamber 1. A rotating blade 5 is fixedly connected to the rotating shaft 4. A convex block 6 is fixedly connected to one end of the rotating shaft 4. Two sets of long rods 10 and one set of short rods 14 are slidably connected inside the annular sealing plate 3. A conical plug 12 is fixedly connected to one end of each of the long rods 10 and short rods 14. A squeezing plate 13 is fixedly connected to the other end of each of the long rods 10 and short rods 14. A first spring 11 is movably sleeved on the outer surface of each of the long rods 10 and short rods 14. A first air supply pipe 17 is connected to the bottom of the regulating chamber 1. A second exhaust pipe 8 is connected to the bottom end of the first air supply pipe 17. One end of the second exhaust pipe 8 is connected to the air inlet chamber 2. A first exhaust pipe 7 is connected to both sides of the regulating chamber 1. A conical block 9 is fixedly connected inside both the first exhaust pipe 7 and the second exhaust pipe 8. A conical hole is opened inside the conical block 9.
[0032] When the rotating blade 5 rotates, the rotating shaft 4 will drive the convex block 6 to rotate. When the protruding end of the convex block 6 rotates to a vertical position, the convex block 6 will drive the short rod 14 to move downward through the squeezing plate 13, and then drive a set of conical plugs 12 to move downward. At this time, the conical plugs 12 will block the interior of a set of conical blocks 9, thereby reducing the oxygen entering the regulating chamber 1 from the first gas pipe 17. At this time, the first spring 11 will push the squeezing plate 13 to move in opposite directions through its rebound, and then drive the long rod 10 to move in opposite directions. When the protruding end of the convex block 6 rotates to a parallel position, the squeezing plate 13 will drive the long rod 10 to move along the first exhaust pipe 7, and then drive the conical plugs 12 to block a set of conical blocks 9. At this time, the first spring 11 will push the squeezing plate 13 to move upward through its rebound, and then drive the short rod 14 to move upward.
[0033] The air intake chamber 2 is connected to an air intake pipe 16, and a blower 15 is fixedly installed at the air intake end of the air intake pipe 16.
[0034] When the blower 15 is started, the gas will enter the air inlet chamber 2 through the air inlet pipe 16, thereby driving the rotating blades 5 to rotate.
[0035] Among them, one end of the first exhaust pipe 7 is connected to the second gas supply pipe 18, one end of the second gas supply pipe 18 is connected to the third gas supply pipe 19, and several component gas supply pipes 20 are fixedly connected to the third gas supply pipe 19.
[0036] When the gas is discharged from the first exhaust pipe 7, the gas then enters the distribution pipe 20 through the second gas supply pipe 18 and the third gas supply pipe 19.
[0037] The first exhaust pipe 7 and the second gas supply pipe 18 are both fixedly connected to one end with flanges, and a flange gasket is placed between the flanges. The two sets of flanges are fixedly connected by bolts.
[0038] The flange makes it easy to assemble and disassemble the second gas pipeline 18 as a whole.
[0039] Among them, several sets of first air outlet pipes 21 are fixedly connected to the air distribution pipe 20, and second air outlet pipes 22 are fixedly connected to the first air outlet pipes 21. The second air outlet pipes 22 are threaded with movable bolts 28, and the second air outlet pipes 22 and the first air outlet pipes 21 are fixed together by the movable bolts 28.
[0040] The presence of movable bolt 28 facilitates the disassembly and replacement of the second air outlet duct 22.
[0041] The top of the second air outlet duct 22 is fixedly connected to an air outlet chamber 23, and the air outlet chamber 23 is provided with several sets of exhaust ports 24.
[0042] When the gas enters the interior of the air outlet chamber 23 through the second air outlet duct 22, it is then discharged through the exhaust port 24.
[0043] Among them, the top of the air outlet chamber 23 is fixedly connected to an arc-shaped cover 25, which is arched in shape.
[0044] The curved cover 25 reduces the pressure damage to the device caused by the high pressure at the bottom of the pool.
[0045] The air outlet chamber 23 has a circular block 26 slidably connected inside, and a second spring 27 is fixedly connected to the bottom of the circular block 26. One end of the second spring 27 is fixedly connected to the air outlet chamber 23.
[0046] When gas enters the air outlet chamber 23, it will cause the circular block 26 to move upward, thus facilitating the gas to be discharged from the exhaust port 24. When the gas stops entering the air outlet chamber 23, the second spring 27 will elastically pull down the circular block 26, thereby causing the circular block 26 to block the exhaust port 24.
[0047] Among them, the circular block 26 is made of lightweight waterproof plastic material.
[0048] Due to the material design of the circular block 26, it is easier for the gas to press against the top of the circular block 26.
[0049] Working principle and usage process of this utility model:
[0050] First, the operator starts the blower 15. At this time, gas is discharged into the air inlet chamber 2 through the air inlet pipe 16, and then into the regulating chamber 1 through the first air delivery pipe 17 and the second exhaust pipe 8. Simultaneously, the gas drives the rotating blades 5 to rotate, which in turn drives the convex block 6 to rotate via the rotating shaft 4. When the protruding end of the convex block 6 rotates to a vertical position, the convex block 6 will cause the short rod 14 to move downwards through the pressing plate 13, thereby causing a set of conical plugs 12 to move downwards and simultaneously press against the openings inside the conical block 9. The conical hole blocks the flow of oxygen into the regulating chamber 1. At the same time, the first spring 11 will push the extrusion plate 13 towards the rotating shaft 4, thereby driving the long rod 10 to move. When the protruding end of the convex block 6 rotates to parallel, the extrusion plate 13 will drive the long rod 10 to move, thereby driving the conical plug 12 to block the conical hole opened inside a set of conical blocks 9. At this time, the first spring 11 will push the extrusion plate 13 upward by rebound, thereby driving the short rod 14 to move upward.
[0051] Subsequently, the gas will enter the second gas supply pipe 18 through the first exhaust pipe 7, and then enter several component gas pipes 20 through the third gas supply pipe 19. At this time, the gas will enter the second exhaust pipe 22 through the first air outlet pipe 21, and then drive the circular block 26 upward when entering the air outlet chamber 23. At this time, the circular block 26 will release the blockage of the exhaust port 24 as it moves upward, and the gas will be discharged through the exhaust port 24. When the gas stops entering the air outlet chamber 23, the second spring 27 will pull the circular block 26 downward through its elasticity, thereby blocking the exhaust port 24.
[0052] Furthermore, the blower 15 of this aeration device can control its frequency at different speeds, adjust the speed of the blower 15, and thus adjust the air volume of the blower 15 itself. This allows personnel to adjust the air volume of the blower 15 according to actual needs, avoiding the blower 15 from rotating at a high frequency continuously. In addition, the blower 15 of this device can be started intermittently through external control equipment, avoiding the need for the aeration device to be constantly running, which further helps to reduce energy consumption.
