Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to an aeration device used for water treatment. Background Art

[0002] Water treatment refers to the process of removing suspended matter, organic matter, bacteria, viruses, inorganic salts and other impurities in water through a series of physical, chemical, biological and other methods to achieve specific water quality standards.

[0003] At present, in wastewater treatment, oxygen is added to the water through an aeration device to promote the growth of aerobic microorganisms and accelerate the biodegradation of organic matter. The most commonly used aeration device is the blower aeration device. The air is compressed by a Roots blower and then transported to the aeration head. The air will be introduced into the sewage from the vertically arranged air outlets on the aeration head to provide oxygen to the microorganisms.

[0004] However, since sewage may contain hard particle impurities, these hard particle impurities may fluctuate during the aeration process and then flow into the air holes on the aeration head with the water flow at the end of aeration, and then cooperate with silt to block the aeration holes of the aeration head, affecting the aeration effect of the aeration device during subsequent use. For this reason, the utility model proposes an aeration device for water treatment to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide an aeration device for water treatment, so as to solve the problem proposed in the above-mentioned background technology that the hard particulate impurities in the sludge will combine with the adhesive sludge to block the aeration holes on the aeration head after the aeration work is completed, resulting in the aeration effect of the aeration device being deteriorated during subsequent use.

[0006] To achieve the above object, the utility model provides the following technical solution: an aeration device for water treatment, the aeration device for water treatment comprising:

[0007] An air guide pipe, one side of which is fixedly connected to an aeration head, one end of which is penetrated by a plurality of air outlet holes distributed in a circular array and one end of which is fixedly connected to a fixing rod, a side of the fixing rod is slidably connected to a slide plate, a side of the slide plate is slidably connected to a plurality of mounting plates, one side of the mounting plate is fixedly connected to a blocking ball, one end of the aeration head is fixedly connected to a plurality of fixing blocks distributed in a circular array, one side of the fixing block is arranged in a "V" shape and both ends of the fixing block are provided with notches corresponding to the positions of the air outlet holes.

[0008] Preferably, a baffle is fixedly connected to one side of the mounting plate, and the baffle and the fixing block are in conformity with each other in shape.

[0009] Preferably, a guide rod arranged in a "polygonal" shape is fixedly connected to one end of the mounting plate, and a mounting hole for slidingly inserting the guide rod is provided on one side of the slide plate.

[0010] Preferably, a spring is provided between the slide plate and the mounting plate, the slide plate is arranged in a "cross" shape and a plurality of obliquely arranged stirring plates are fixedly connected to the side of the slide plate.

[0011] Preferably, one end of the guide rod is fixedly connected to a first limit plate for preventing the slide plate from falling off, and one end of the guide rod is fixedly connected to a second limit plate for preventing the mounting plate from slipping off.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The device arranges a blocking ball on the aeration head, and the blocking ball can slide vertically and rotate horizontally on the aeration head, so as to cooperate well with the compressed air to lead out the air outlet. After the aeration device is used, the blocking ball will slide into the air outlet through the cooperation of the fixed block to block the air outlet, so as to prevent hard particle impurities from flowing into the air outlet and clogging the air outlet. This also solves the problem that the hard particle impurities in the sludge will cooperate with the adhesive sludge to block the aeration holes on the aeration head after the aeration work is completed, resulting in the deterioration of the aeration effect of the aeration device during subsequent use.

[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] Embodiment 1: An aeration device for water treatment, the aeration device for water treatment comprising:

[0025] Specifically, an aeration head 2 is fixedly connected to one side of the air guide pipe 1, and a plurality of air outlet holes 21 distributed in a circular array are formed through one end of the aeration head 2, and a fixing rod 3 is fixedly connected to one end of the aeration head 2. Compressed air will be discharged from the air outlet hole 21 through the air guide pipe 1 and the aeration head 2. A slide plate 4 is slidably connected to the side of the fixing rod 3, and a plurality of mounting plates 5 are slidably connected to the side of the slide plate 4. A blocking ball 8 is fixedly connected to one side of the mounting plate 5. The blocking ball 8 can slide vertically and rotate on a horizontal plane through the fixing rod 3, the slide plate 4 and the mounting plate 5, so that the blocking ball 8 can better adapt to the aeration work. A plurality of fixing blocks 6 distributed in a circular array are fixedly connected to one end of the aeration head 2, and one side of the fixing block 6 is set in a "V" shape and both ends of the fixing block 6 are provided with notches 61 corresponding to the positions of the air outlet holes 21, so that the blocking ball 8 can slide into the air outlet holes 21 under the action of its own weight, thereby blocking the air outlet holes 21 and preventing hard debris from falling into the air outlet holes 21.

[0026] In order to better block debris, a baffle 7 is fixedly connected to one side of the mounting plate 5 of the present application, and the shapes of the baffle 7 and the fixing block 6 fit together, which can not only further block hard debris on the outside of the air outlet 21, but also provide support for the blocking ball 8.

[0027] In order to facilitate the sliding installation of the mounting plate 5, one end of the mounting plate 5 of the present application is fixedly connected with a guide rod 51 arranged in a "polygonal shape", and one side of the skateboard 4 is provided with a mounting hole 41 for the guide rod 51 to be slidably inserted, so that the mounting plate 5 can be slidably installed on the skateboard 4. At the same time, the polygonal guide rod 51 can also prevent the mounting plate 5 from rotating, thereby allowing the baffle 7 to better fit the fixed block 6.

[0028] In order to better allow the blocking ball 8 to slide into the air outlet 21, a spring 52 is provided between the slide plate 4 and the mounting plate 5 of the present application. The spring 52 can give a reaction force to the mounting plate 5 so that the blocking ball 8 can better slide into the air outlet 21. Of course, the elasticity of the spring 52 should take into account the impact force of the compressed air to prevent the blocking ball 8 from affecting the discharge of the compressed air. The slide plate 4 is arranged in a "cross" shape and a plurality of inclined stirring plates 9 are fixedly connected to the side of the slide plate 4, so that the slide plate 4 can rotate better. When rotating, the stirring plate 9 will stir the sewage around the aeration head 2 to form a certain degree of vortex, so that hard debris can be better away from the aeration head 2 under the action of centrifugal force.

[0029] In order to make the structural installation more stable, one end of the guide rod 51 of the present application is fixedly connected to the No. 1 limit plate 31 for preventing the slide plate 4 from detaching, and one end of the guide rod 51 is fixedly connected to the No. 2 limit plate 53 for preventing the mounting plate 5 from slipping. The No. 1 limit plate 31 and the No. 2 limit plate 53 can make the slide plate 4 and the mounting plate 5 more stable when sliding.

[0030] During actual use, the compressed air will push the blocking ball 8 upward, allowing the blocking ball 8 to drive the baffle 7, the mounting plate 5 and the slide plate 4 to slide and slide out of the air outlet 21. Then, under the fluctuation of the water flow, the slide plate 4 will rotate on the fixing rod 3, and at the same time drive the blocking ball 8 to rotate. Moreover, the compressed air will also better drive the slide plate 4 to rotate after contacting the stirring plate 9, so that the air outlet 21 can be exposed to ensure the operation of the aeration device. At the end of aeration, the slide plate 4, the mounting plate 5, and the blocking ball 8 will all slide down. The blocking ball 8 will first contact the fixing block 6, and then, under its own weight and the cooperation of the spring 52, it will slide into the air outlet 21 from the surface of the fixing block 6, and cooperate with the baffle 7 to safely block the air outlet 21 to prevent hard debris from falling into the air outlet 21, thereby ensuring the aeration effect.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
