Description

Technical Field

[0001] The utility model relates to the technical field of aeration, in particular to a combined aerator. Background Art

[0002] Aerators are essential equipment for aeration and oxygenation of water supply and drainage. According to their usage methods, they can be divided into surface aerators and underwater aerators. Among them, microporous aerators are widely used due to their high oxygen transfer efficiency and good anti-pollution effect.

[0003] An aerator is generally composed of an aeration tube and an air pump. Usually, the aeration tube is fixed to the bottom of the sewage pool. Therefore, when the micropores of the aeration tube are blocked, the sewage in the sewage pool needs to be emptied before the aeration tube can be disassembled for maintenance. Secondly, since the aeration tube is relatively close to the bottom of the pool, the sediment in the sewage pool will settle in the sewage pool, and the sediment at the bottom of the aeration tube will continue to accumulate. After the accumulated sediment covers the aeration tube, it will affect the aeration effect. Secondly, there are a large number of aeration tubes installed at the bottom of the sewage pool, and the installation and construction takes a lot of time. Therefore, the utility model proposes a combined aerator. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a combined aerator.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined aerator, comprising a first right-angle plate and a second right-angle plate, the first right-angle plate and the second right-angle plate are respectively fixed on both sides of the top of the sewage pool, a horizontal pipe is fixedly connected between the first right-angle plate and the second right-angle plate, an air pump connected to the horizontal pipe is fixedly connected to the surface of the first right-angle plate, a branch pipe is fixedly connected to the lower surface of the middle part of the horizontal pipe, a rotating pipe is sealed and rotatably connected to the bottom end surface of the branch pipe, a vertical pipe is provided at the bottom end of the rotating pipe, and a connecting component is provided at the top of the vertical pipe and the surface of the rotating pipe, a bottom pipe is fixedly connected to the bottom end of the vertical pipe, a plurality of aeration heads are equidistantly installed on the lower surface of the bottom pipe, a motor is fixed to the upper surface of the second right-angle plate, and a transmission component is commonly connected between the output shaft of the motor and the rotating pipe.

[0006] Furthermore, a plurality of threaded heads are fixed on the lower surface of the bottom pipe, and the aeration head is rotatably connected to the threaded head through threads.

[0007] Furthermore, the connecting assembly includes a top plate fixed to the top of the vertical tube and a limit plate fixed to the outer wall of the rotating tube, the limit plate is provided with insertion holes on both sides, two plug blocks passing through the insertion holes are fixed on the upper surface of the top plate, the plug blocks are provided with a groove on the side away from the rotating tube, a spring is fixedly connected to the inner wall of the groove, the other end of the spring is fixedly connected to a latch tooth, and the latch tooth is located on the upper surface of the limit plate.

[0008] Furthermore, a plurality of annular grooves are formed at the top of the inner side wall of the vertical pipe, and sealing rings are clamped inside the annular grooves.

[0009] Furthermore, the exhaust port of the air pump is connected to the cross pipe through a pipeline.

[0010] Furthermore, the transmission assembly includes a driving wheel fixed to the output shaft of the motor and a driven wheel fixed to the outer side wall of the rotating tube, and a belt is commonly connected to the surfaces of the driving wheel and the driven wheel.

[0011] Beneficial effects of the utility model:

[0012] 1. When the utility model is in use, the combined aerator is provided with a first right-angle plate, a second right-angle plate, a horizontal pipe, an air pump, a branch pipe, a rotating pipe, a vertical pipe, a bottom pipe, an aeration head and a connecting assembly. The vertical pipe can be quickly assembled and fixed to the bottom of the rotating pipe through the connecting assembly. After air is pumped into the horizontal pipe by the air pump, the air can enter the bottom pipe along the branch pipe, the rotating pipe and the vertical pipe, and finally be discharged from the aeration head to achieve aeration. Therefore, when the bottom aeration head is blocked, the vertical pipe can be quickly disassembled from the bottom of the rotating pipe, and then the vertical pipe together with the bottom pipe can be lifted out of the sewage pool, which is convenient for cleaning or replacing the aeration head.

[0013] 2. When the utility model is in use, the combined aerator is provided with a bottom pipe, an aeration head, a motor and a transmission assembly. Through the transmission of the transmission assembly, the motor can drive the rotating pipe and the vertical pipe to rotate, thereby driving the bottom pipe and the aeration head at the bottom to rotate, which can increase the aeration range. Therefore, the number of aeration pipes installed in the same sewage pool can be reduced, and the installation is faster and more convenient. Secondly, the aeration head faces downward, and the bottom pipe can stir the sewage at the bottom of the sewage pool when it rotates to prevent the sludge from settling at the bottom of the pool.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A plurality of threaded heads 12 are fixed to the lower surface of the bottom pipe 10 , and the aeration head 11 is rotatably connected to the threaded heads 12 through threads.

[0023] Therefore, the aeration head 11 can be connected or disassembled with the threaded head 12 through the thread, and when the aeration head 11 is blocked, it can be quickly disassembled for maintenance or replacement.

[0024] The connecting assembly 13 includes a top plate 131 fixed to the top of the vertical tube 9 and a limit plate 132 fixed to the outer wall of the rotating tube 6. Plug holes 133 are provided on both sides of the limit plate 132. Two plug blocks 134 passing through the plug holes 133 are fixed on the upper surface of the top plate 131. The plug blocks 134 are provided with a groove 135 on the side away from the rotating tube 6. A spring 136 is fixedly connected to the inner wall of the groove 135. The other end of the spring 136 is fixedly connected to a latch tooth 137. The latch tooth 137 is located on the upper surface of the limit plate 132.

[0025] When connecting the vertical tube 9 with the rotating tube 6, the top end of the vertical tube 9 is directly sleeved on the bottom end surface of the rotating tube 6, and the plug block 134 is inserted into the inside of the socket 133. During the insertion process, the latch 137 will be squeezed back into the inside of the groove 135 by the side wall of the socket 133. After the latch 137 passes over the socket 133, the latch 137 is ejected by the spring 136, and the latch 137 is stuck on the surface of the limit plate 132, thereby realizing the connection between the vertical tube 9 and the rotating tube 6.

[0031] Working principle: Start the air pump 4 to pump air into the horizontal pipe 3, the air enters the vertical pipe 9 along the branch pipe 5 and the rotating pipe 6, then enters the bottom pipe 10 and is discharged from the aeration head 11 at the bottom, thereby achieving aeration. At the same time, start the motor 7, drive the rotating pipe 6 and the vertical pipe 9 to rotate through the transmission assembly 8, so that the aeration head 11 rotates in the sewage tank to increase the aeration range.
