Description

Technical Field

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

[0002] Cyclone aerators are mainly used in sewage treatment and aquaculture to improve water quality and enhance biological activity by increasing the oxygen content in water.

[0003] As an efficient water treatment equipment, cyclone aerator is widely used in many fields. It effectively injects air into water by generating a rotating airflow, which not only improves the dissolution efficiency of oxygen, but also promotes the activity of microorganisms in the water. This aeration method not only improves the sewage treatment effect, but also helps maintain the balance of the aquatic ecosystem.

[0004] Reference is made to the utility model patent with authorized publication number CN219117282U, which discloses a cyclone aerator, comprising a cylinder, an aeration plate provided on the upper side of the cylinder, an aeration needle provided circumferentially on the lower side of the aeration plate, a threaded rod passing through the center of the aeration plate, an air inlet elbow provided on the bottom side of the cylinder, an air jet ring connected to the upper end of the air inlet elbow, a guide protrusion provided in the center of the air jet ring, an annular nozzle provided between the guide protrusion and the air jet ring, and a support bar provided inside the annular nozzle.

[0005] During use, the above patent has a too compact internal structure of the cylinder and dense aeration needles are arranged on the aeration disk. In actual operation, since it works in sewage, it is easy to cause blockage and jamming. Therefore, the practicality of the above patent is not high. For this reason, we propose a cyclone aerator to solve the above shortcomings. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cyclone aerator.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A cyclone aerator comprises an outer cylinder and an inner cylinder, wherein upper rotating blades and lower rotating blades are connected and installed between the outer cylinder and the inner cylinder, upper and lower rib plates are connected to the inner side of the inner cylinder, and an air inlet pipe is provided at the inner ends of the upper and lower rib plates, a fixed base is fixedly installed on the lower side of the air inlet pipe, a ventilation pipe is fixedly installed on the upper side of the fixed base, an annular pipe is connected and installed on the upper side of the ventilation pipe, aeration holes are evenly and symmetrically opened on the oblique lower side of the annular pipe, or a microporous aerator is installed on the annular pipe.

[0009] Preferably, the outer cylinder, inner cylinder, upper rotating blades and lower rotating blades are all made of corrosion-resistant stainless steel.

[0010] Preferably, the annular tube is manufactured by a special process.

[0011] Preferably, the upper rotating blades and the lower rotating blades are arranged in several groups at equal intervals along the circumference of the outer cylinder, and the upper rotating blades and the lower rotating blades are arranged in a staggered manner.

[0012] Preferably, the outer ends of the upper rib and the lower rib are connected to the inner tube.

[0013] Preferably, the inner ends of the upper rib plate and the lower rib plate are fixedly connected with a rotating sleeve, and the rotating sleeve is rotatably sleeved on the wall of the air intake pipe.

[0014] Preferably, the interior of the fixed base is a hollow structure and the fixed base is communicated with the interiors of the air inlet pipe and the vent pipe respectively.

[0015] Preferably, the fixed base is a circular structure, and the ventilation pipes are arranged in several groups at equal distances along the circumference of the upper side of the fixed base.

[0016] Preferably, several groups of outer stirring blades are installed on the lower part of the outer wall of the outer cylinder.

[0017] Compared with the related art, the cyclone aerator proposed in this utility model has the following beneficial effects:

[0018] In the present invention, a cyclone aerator is described, wherein a power source blower is input into an annular tube through an air inlet pipe. Air flows out along aeration holes evenly arranged at the oblique lower portion of the annular tube. The gas exiting the aeration holes mixes with the sewage in the cylinder, forming a soda-water mixture, which has a density less than that of the sewage and moves upward along the cylinder. When the soda-water mixture touches the rotating blades, it pushes the inner cylinder, outer cylinder, and rotating blades to automatically rotate synchronously around the air inlet pipe. Under the action of the driving force, the aerator rotates. During the rotation, the rotating blades evenly cut the bubbles again, forming microporous aeration, increasing oxygen demand and significantly improving the aeration effect, achieving the purpose of increasing efficiency and energy saving. At the same time, the rotating cylinder stirs the sludge at the bottom of the pool, reducing sludge accumulation at the bottom of the pool. In addition, the aerator has a simple structure, and the connection structure space between the outer cylinder, inner cylinder, and rotating blades is large, which is less likely to cause blockage and jamming when working in sewage, thereby improving practicality.

[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Example 1:

[0024] Reference Figure 1-2 A cyclone aerator comprises: an outer tube 1 and an inner tube 2, an upper rotating blade 3 and a lower rotating blade 4 are connected and installed between the outer tube 1 and the inner tube 2, an upper rib plate 5 and a lower rib plate 6 are connected to the inner side of the inner tube 2, an air inlet pipe 8 is provided at the inner end of the upper rib plate 5 and the lower rib plate 6, a fixed base 9 is fixedly installed on the lower side of the air inlet pipe 8, a ventilation pipe 10 is fixedly installed on the upper side of the fixed base 9, an annular pipe 11 is connected and installed on the upper side of the ventilation pipe 10, and aeration holes 12 are evenly distributed on the oblique lower side of the annular pipe 11, and the annular pipe 11 is made of non-standard material.

[0025] Through the above arrangement, the outer cylinder 1, the inner cylinder 2, the upper rotating blades 3 and the lower rotating blades 4 form an integral rotating body structure. When the upper rotating blades 3 and the lower rotating blades 4 rotate, they can cut the water bubbles formed from the annular tube 11, so that one bubble becomes multiple tiny bubbles, thereby forming microporous aeration, increasing the oxygen demand and improving the aeration effect.

[0026] In this embodiment, the outer cylinder 1, the inner cylinder 2, the upper rotating blades 3 and the lower rotating blades 4 are all made of corrosion-resistant stainless steel.

[0027] By the above arrangement, the outer cylinder 1, the inner cylinder 2, the upper rotating blades 3 and the lower rotating blades 4 are all made of corrosion-resistant stainless steel, thereby increasing the service life of the device.

[0028] In this embodiment, several groups of upper rotating blades 3 and lower rotating blades 4 are equidistantly arranged along the circumference of the outer cylinder 1 , and the upper rotating blades 3 and lower rotating blades 4 are staggered.

[0029] By the arrangement in the above manner, the upper rotating blades 3 and the lower rotating blades 4 are staggered, so that the bubbles cut by the lower rotating blades 4 are more likely to be cut again by the staggered upper rotating blades 3 when moving upward, shortening the time interval between the two cuttings, thereby improving the aeration efficiency.

[0030] In this embodiment, the outer ends of the upper rib plate 5 and the lower rib plate 6 are connected to the inner tube 2, and the inner ends of the upper rib plate 5 and the lower rib plate 6 are fixedly connected to the rotating sleeve 7, which is rotatably sleeved on the wall of the intake pipe 8.

[0031] By the above arrangement, the rotary sleeve 7 is arranged so that the rotating body formed by the outer cylinder 1, the inner cylinder 2, the upper rotary blades 3 and the lower rotary blades 4 can rotate with the air inlet pipe 8 as the rotation center through the rotary sleeve 7.

[0032] In this embodiment, the interior of the fixed base 9 is a hollow structure and the fixed base 9 is communicated with the interiors of the air inlet pipe 8 and the air vent pipe 10 respectively.

[0033] Through the above-mentioned arrangement, the cavity structure inside the fixed base 9 provides an air delivery channel for the air intake pipe 8 , and the fixed base provides support for the air intake pipe 8 .

[0034] In this embodiment, the fixed base 9 is a circular structure, and several groups of vent pipes 10 are evenly spaced along the circumference of the upper side of the fixed base 9 .

[0035] By the above arrangement, several groups of vent pipes 10 are evenly spaced along the circumference of the upper side of the fixed base 9, thereby forming several evenly distributed support connection points for the bottom of the vent pipes 10, making the connection of the vent pipes 10 more stable.

[0036] In this embodiment, several groups of outer stirring blades 13 are installed on the lower portion of the outer wall of the outer cylinder 1 .

[0037] By setting in the above manner, the stirring function of the equipment on the sludge at the bottom of the pool is increased, and the sludge accumulation at the bottom of the pool is reduced.

[0038] The working principle of the cyclone aerator provided by the utility model is as follows:

[0039] During use, the blower inputs air into the air inlet pipe 8, and the air is input into the cavity inside the fixed base 9 from the air inlet pipe 8, and then enters the vent pipe 10 from the cavity of the fixed base 9, and the air is input into the annular tube 11 by the vent pipe 10. The air flows out from the aeration holes 12 at the oblique lower part of the annular tube 11, and mixes with the sewage inside the outer cylinder 1 and the inner cylinder 2 to form a soda-water mixture, and then its density is less than the sewage density, and moves upward along the cylinder. When the soda-water mixture touches the lower rotating blade 4, it pushes the inner cylinder 2, the outer cylinder 1, the upper rotating blade 3 and the lower rotating blade 4 to rotate synchronously around the air inlet pipe 8. Under the action of the driving force, during the rotation process, the lower rotating blade 4 evenly cuts the bubbles again to form microporous aeration. Subsequently, the bubbles cut by the lower rotating blade 4 move upward and are cut again under the rotation action of the upper rotating blade 3, further forming microporous aeration, increasing the oxygen demand, and significantly improving the aeration effect.

[0040] Example 2:

[0041] The difference between this embodiment and the first embodiment is that the aeration holes 12 uniformly and symmetrically opened on the oblique lower side of the annular tube 11 can be replaced by a microporous aerator installed on the annular tube 11. Its working principle is the same as that of the first embodiment. The microporous aerator is a high-efficiency aeration equipment component used for sewage treatment. Its function is to inject air into the sewage to increase the oxygen concentration in the sewage and promote the activity of microorganisms in the biological treatment process. This is a common equipment in existing sewage treatment and will not be described in detail here.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
