For convenience of explanation of the working principle, in this embodiment, n=3, the first hollow shaft 31 is the outermost hollow shaft, the fan blade on the first hollow shaft 31 is located at the air inlet 11 of the air compression chamber 1, the fan blade on the first hollow shaft 31 is defined as the first fan blade 61, the fan blade on the second hollow shaft 32 is defined as the second fan blade 62, and the fan blade on the third hollow shaft 33 is defined as the third fan blade 63; the area between the first fan blade 61 and the second fan blade 62 is defined as a "first compression chamber 71", the area between the second fan blade 62 and the third fan blade 63 is defined as a "second compression chamber 72", and the area between the third fan blade 63 and the air outlet 12 of the air compression chamber 1 is defined as a "third compression chamber 73", and since the cross-sectional area of the air compression chamber 1 gradually decreases from the air inlet 11 to the air outlet 12, the volume of the first compression chamber 71 is larger than the volume of the second compression chamber 72, and the volume of the second compression chamber 72 is larger than the volume of the third compression chamber 73.
When the device works, the driving device 4 drives the 3 hollow shafts to synchronously rotate, the rotating speeds of the 3 hollow shafts are sequentially increased, the rotating speed of the first hollow shaft 31 is 3600 revolutions per minute, the rotating speed of the second hollow shaft 32 is 7200 revolutions per minute, and the rotating speed of the third hollow shaft 33 is 10800 revolutions per minute; the air outside the air compression chamber 1 is sucked into the first compression cavity 71 through the first fan blade 61, the rotation speed of the second fan blade 62 is higher than that of the first fan blade 61, so that the pressure at the second fan blade 62 is lower than that at the first fan blade 61, and the air is pushed into the second compression cavity 72 to be compressed, then the pressure at the third fan blade 63 is lower than that at the second fan blade 62 because the rotation speed of the third fan blade 63 is higher than that of the second fan blade 62, so that the air is pushed into the third compression cavity 73 to be further compressed, finally the compressed air is discharged into water through the air outlet 12 of the air compression chamber 1 and a plurality of aeration assemblies, and the aeration pipe 92 disperses and escapes the compressed air in the form of bubbles, so that oxygen in the air is dissolved into water, the oxygen content of the water is increased, and the production requirement of fish in the water is guaranteed. The driving device 4 drives the fan blades on the plurality of hollow shafts to synchronously rotate and the rotating speed is sequentially increased, so that the air flow is sucked into the air compression chamber 1 and then compressed step by step, and therefore, the oxygenation device provided by the invention has the advantages of stable oxygenation effect and low energy consumption, and meets oxygenation requirements. It will be appreciated that the axle housing 2 is stationary and the rotational speed of movement of the first quill 31 relative to the axle housing 2 is 3600 rpm, i.e. the bearing 5 arranged between the axle housing 2 and the first quill 31 is subjected to a rotational speed of 3600 rpm; since the rotational speed of movement of the second hollow shaft 32 relative to the first hollow shaft 31 is 3600 rpm (the difference in rotational speed between the second hollow shaft 32 and the first hollow shaft), the bearing 5 disposed between the first hollow shaft 31 and the second hollow shaft 32 is subjected to a rotational speed of 3600 rpm; the rotation speed of the third hollow shaft 33 relative to the second hollow shaft 32 is 3600 rpm (the difference between the rotation speeds of the third hollow shaft 33 and the second hollow shaft 32), that is, the bearing 5 arranged between the second hollow shaft 32 and the third hollow shaft 33 bears 3600 rpm; therefore, the rotation speed of each bearing 5 is the same, and even if the third fan blade 63 rotates at the ultra-high speed, the rotation speed exceeds 10000 revolutions per minute, but the bearing 5 still bears the low-speed rotation, the bearing 5 can not generate heat and deform due to the high-speed rotation, the clamping damage is caused, the good working condition is maintained, and the service life is long.
Specifically, referring to fig. 2, the automatic pressure regulator 93 includes a valve body 931 disposed vertically, an air inlet 935 and an air outlet 936 disposed at the top and bottom of the valve body 931, a float 932 disposed in the inner cavity of the valve body 931, and an air outlet protrusion 933 disposed on the bottom wall of the inner cavity of the valve body 931, the air outlet protrusion 933 being disposed hollow and communicating with the air outlet 936, a plurality of air outlet slots 934 being disposed circumferentially on the top of the air outlet protrusion 933, the air inlet 935 on the valve body 931 being connected to the conduit 91, the air outlet 936 on the valve body 931 being connected to the aeration tube 92. When no compressed air enters the inner cavity of the valve body 931, water flows back into the inner cavity of the valve body 931, the floating ball 932 is in a floating state, the air outlet 936 is in a conducting state, and after the compressed air is input, the compressed air can permeate into the water; when the pressure of the compressed air is too high or the output is excessive, the air pressure discharges the water of the valve body 931, then the floating ball 932 is propped against the top of the exhaust protrusion 933 after losing the buoyancy of the water, so that the gas can only pass through the exhaust groove 934 and the exhaust hole 936 in sequence and be sent to the aeration pipe 92, thereby the compressed air is output from the exhaust hole 936 to a limited extent, the rest of the compressed air can be sent to other aeration pipes 92, the condition that the output pressure of the aeration pipe 92 close to the air outlet 12 of the air compression chamber 1 is too high and the output pressure of the aeration pipe 92 far away from the air outlet 12 of the air compression chamber 1 is too low is avoided, and the aeration pressure of the aeration pipe 92 is automatically adjusted, so that the uniform and reasonable aeration effect is achieved.
Specifically, as shown in fig. 1, the air compression chamber 1 is in a truncated cone shape, the air compression chamber 1 gradually contracts in the transverse direction, the air inlet 11 and the air outlet 12 are respectively formed at two ends of the air compression chamber 1, the diameter of the air inlet 11 is larger than that of the air outlet 12, that is, the air inlet 11 is arranged at the large-diameter end of the air compression chamber 1, and the air outlet 12 is arranged at the small-diameter end of the air compression chamber 1.
Further, as shown in fig. 1, in order to make each fan blade fit with the inner wall of the truncated cone-shaped air compression chamber 1, the diameters of the fan blades on the N hollow shafts are sequentially reduced, and the diameter of the fan blade on the N hollow shaft is the smallest; the distance between the outer circumference of each fan blade and the inner wall of the air compression chamber 1 is equal, the structure is compact, and the air flow convergence performance is good. In addition, the axial distance between every two adjacent fan blades is equal, and through the arrangement, the space of the compression cavity in the air compression chamber 1 is gradually decreased, and the air can be stably and uniformly compressed, so that the noise emitted by the equipment is reduced.
Preferably, as shown in fig. 1, the fan blade includes a shaft sleeve 34, and a plurality of blades 35 fixed on the outer wall of the shaft sleeve 34, where the shaft sleeve 34 is sleeved on a corresponding hollow shaft and fixedly connected with the hollow shaft (e.g. locked by a locking screw). The detachable connection between the fan blade and the hollow shaft is convenient, and the fan blade is convenient to replace even if damaged.
Specifically, as shown in fig. 1, the driving device 4 includes a driving motor 44, a transmission shaft 45 drivingly connected to an output shaft of the driving motor 44, and a plurality of sets of transmission assemblies; each group of transmission components corresponds to a hollow shaft, and each transmission component comprises a driving wheel 41 sleeved on a transmission shaft 45, a driven wheel 42 sleeved on the tail part of the corresponding hollow shaft and a transmission belt 43; the driving wheel 41 and the driven wheel 42 are in driving connection by a driving belt 43. Here, the driving wheel 41 and the driven wheel 42 are preferably synchronous pulleys, and the driving belt 43 is preferably a synchronous belt, which has the advantages of high driving efficiency, stable driving and no slipping.
In order to make each hollow shaft have enough positions to be in transmission connection with the driving device 4, the transmission section length of the N hollow shafts sequentially increases along the direction away from the air compression chamber 1, and the transmission section of the N hollow shaft is longest. In addition, in order to ensure that the rotation speed of the N hollow shafts increases gradually, the rotation speed of the N hollow shafts (i.e. the innermost hollow shaft) is the highest, so that the transmission ratio of the transmission assemblies corresponding to the N hollow shafts decreases gradually, the transmission ratio can be understood as a value of the rotation speed of the driving wheel 41 divided by the rotation speed of the driven wheel 42, and since the driving wheels 41 of each group of transmission assemblies are all arranged on the transmission shaft 45, the rotation speed of each driving wheel 41 is the same, the smaller the transmission ratio, the higher the driven wheel 42, and the transmission ratio can be obtained by adjusting the number of teeth of the synchronous pulley.
Preferably, the air inlet 11 of the air compression chamber 1 is provided with a filter screen 10, which can filter impurities and dust in the outside air, prevent the impurities and dust from being sucked into the air compression chamber to cause the blockage of the air outlet of the air compression chamber, and ensure the purity of the compressed air.
Preferably, the bearing 5 can be a plane bearing 5 because the bearing 5 has a low rotation speed, the plane bearing 5 can be directly purchased from the market, the price is low, and the working condition is good.
