Description

Technical Field

[0001] This utility model specifically relates to the field of aerator technology, and more specifically to a permanent magnet synchronous aerator. Background Technology

[0002] An aerator is a device that increases the dissolved oxygen content in water. It is widely used in aquaculture, sewage treatment and other fields, and is crucial for maintaining the ecological balance of aquatic bodies and protecting the living environment of organisms.

[0003] Chinese Patent Application No. 201820999505.7 discloses an impeller for an aerator and an aerator with the impeller, including a float, a support head, and a support rod. The support head is provided on the upper side of the float, and there are three support heads. The support rod is provided on the side of the support head away from the float, and there are three support rods. A connecting seat is provided on the side of the support rod away from the support head, and a protective cover is provided on the upper side of the connecting seat.

[0004] The aerator in the aforementioned patent has a conical impeller with multiple impellers arranged on the conical surface and a counterweight plate. When in use, the impeller is submerged in water due to the counterweight plate. When the impellers rotate, they can only stir the water below the surface and it is difficult to agitate the water. Therefore, it is difficult for the water to come into better contact with the air. The aerator has a very poor oxygenation effect. Utility Model Content

[0005] The purpose of this invention is to provide a permanent magnet synchronous aerator. The use of the arc-shaped part in conjunction with the upright part will increase the turbulence of the water during rotation, making it easier for the water to be dispersed into more small water droplets and waves, which greatly increases the contact area between water and air. Moreover, the convection between the upper and lower water layers brought about by the upright part allows more water with low oxygen content at the bottom to be brought to the surface to contact the air, thereby improving the overall oxygenation efficiency; thus solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A permanent magnet synchronous aerator, comprising

[0008] The drive assembly, which drives the dial assembly, has multiple metal rods arranged in a circular array on its outer side; one end of each metal rod is fixed to the dial assembly by bolts, and the other end is inserted into the upper end of the float box and fixed by bolts.

[0009] The deflector assembly includes a water deflector, on the outer side of which multiple deflectors are arranged in a circular array. Each deflector consists of an arc-shaped part and an upright part, wherein the upright part is located at the upper end of the arc-shaped part; both the arc-shaped part and the upright part are provided with through holes.

[0010] The upper end of the pontoon has an "S"-shaped protrusion, and a rectangular slot is provided in the middle of the protrusion to facilitate the insertion of a metal rod.

[0011] As a further technical solution of this utility model, the dial assembly includes a housing cover, which is fixed to the housing bottom cover by bolts around its perimeter. A stator is provided inside the housing cover, and the stator is embedded and fixed to the housing cover. A rotor is installed on the outside of the stator. A drive shaft for power output is also installed at the bottom of the rotor.

[0012] As a further technical solution of this utility model, a tapered roller bearing is also installed on the drive shaft, and a deep groove ball bearing is coaxially installed below the tapered roller bearing; then the tapered roller bearing and the deep groove ball bearing are both installed in the bearing cage; the bearing cage is fixed to the bottom cover of the housing by bolts.

[0013] As a further technical solution of this utility model, the lower end of the drive shaft is connected to the rotating upper cover by a key, and bolts are inserted along the radial position of the drive shaft for reinforcement and fixation; a rotating bottom shell is fixedly installed at the lower end of the rotating upper cover; a dial assembly is provided at the bottom of the rotating bottom shell.

[0014] As a further technical solution of this utility model, the interior of the rotating base shell is also provided with a counterweight plate; the counterweight plate is provided with multiple bolts, and the tail end of the bolt passes through the counterweight plate and the rotating base shell and is fixedly connected to the dial assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the float box uses the buoyancy of the water to float the entire aerator on the water surface; during operation, the drive component drives the dial component to rotate, thereby agitating the water to achieve the effect of oxygenation.

[0017] 2. In this utility model, when the water-dispensing wheel rotates at high speed, the arc-shaped part can generate water flow in a circular direction, while the upright part can apply an additional vertical force to the water body during the rotation of the water-dispensing wheel. This allows the water body to not only move in a circular motion on the plane, but also generate convection in the vertical direction, promoting the exchange of water between the upper and lower layers. Compared with the impeller of a traditional aerator, it can drive more water body to participate in the flow, and the water dispensing range and effect are better.

[0018] 3. In this utility model, the combination of the upright part and the arc-shaped part of the water wheel increases the turbulence of the water when it rotates. The upright part makes it easier for the water to be dispersed into more small water droplets and waves, which greatly increases the contact area between the water and the air. Moreover, the convection between the upper and lower water layers brought about by the upright part allows more of the water at the bottom layer, which originally had low oxygen content, to be brought to the surface to contact the air, thereby improving the overall oxygenation efficiency.

[0030] 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.

[0031] Please see Figure 1-9 In this embodiment of the utility model, a permanent magnet synchronous aerator includes a drive assembly 1. The drive assembly 1, which is used to drive the dial assembly 2, has multiple metal rods 3 arranged in a ring array on its outer side. One end of each metal rod 3 is fixed to the dial assembly 2 by bolts, and the other end is inserted into the upper end of the float box 4 and fixed by bolts.

[0032] The dial assembly 2 includes a water-dispensing wheel 21. The outer side of the water-dispensing wheel 21 is provided with multiple dispensing blades in a circular array. Each dispensing blade is composed of an arc-shaped part 22 and an upright part 23, wherein the upright part 23 is located at the upper end of the arc-shaped part 22. Both the arc-shaped part 22 and the upright part 23 are provided with through holes.

[0033] By adopting the above technical solution, when in use, the float box 4 uses the buoyancy of the water to float the entire aerator on the water surface; when working, the drive component 1 drives the dial component 2 to rotate, thereby agitating the water body to achieve the effect of oxygenation.

[0034] Furthermore, when the water impeller 21 rotates at high speed, the arc-shaped part 22 can generate water flow in a circular direction, while the upright part 23 can apply an additional vertical force to the water body during the rotation of the water impeller 21, so that the water body not only makes circular motion on the plane, but also generates convection in the vertical direction, promoting the exchange of water between the upper and lower layers. Compared with the impeller of a traditional aerator, it can drive more water body to participate in the flow, and the range and effect of water dispensing are better.

[0035] With the cooperation of the upright part 23 and the arc-shaped part 22 of the water wheel 21, the turbulence of the water will be increased when it rotates. The upright part 23 makes it easier for the water to be dispersed into more small water droplets and waves, which greatly increases the contact area between water and air. Moreover, the convection between the upper and lower water layers brought about by the upright part 23 can bring more water with low oxygen content at the bottom layer to the surface to contact the air, thereby improving the overall oxygenation efficiency.

[0036] The upper end of the float box 4 has an "S"-shaped protrusion, and a rectangular slot is provided in the middle of the protrusion to facilitate the insertion of the metal rod 3.

[0037] By adopting the above technical solution, the "S"-shaped protrusion can wrap around and fix one end of the metal rod 3, and can be tightened with bolts on both sides, thereby avoiding loosening.

[0038] In this embodiment, the dial assembly 2 includes a housing cover 5, which is fixed to the housing bottom cover 8 by bolts. A stator 6 is provided inside the housing cover 5, and the stator 6 is embedded and fixed to the housing cover 5. A rotor 7 is installed on the outside of the stator 6. A drive shaft 12 for power output is also installed at the bottom of the rotor 7.

[0039] More specifically, a tapered roller bearing 13 is also installed on the drive shaft 12, and a deep groove ball bearing is coaxially installed below the tapered roller bearing 13; both the tapered roller bearing 13 and the deep groove ball bearing are installed in the bearing cage 14; the bearing cage 14 is fixed to the bottom cover 8 of the housing by bolts.

[0040] By adopting the above technical solution, this utility model uses an inner stator and an outer rotor to drive the dial assembly 2. The dial assembly 2 rotates synchronously with the rotor 7, resulting in higher speed stability.

[0041] The tapered roller bearing 13 can ensure the normal rotation of the rotor 7 and bear a certain axial force from the rotor 7, thus ensuring the stability of the rotor 7 during rotation.

[0042] In this embodiment, the lower end of the drive shaft 12 is connected to the rotating upper cover 9 by a key, and bolts are inserted along the radial position of the drive shaft 12 for reinforcement and fixation; a rotating bottom shell 10 is fixedly installed at the lower end of the rotating upper cover 9; a dial assembly 2 is provided at the bottom of the rotating bottom shell 10.

[0043] More specifically, the interior of the rotating base 10 is also provided with a counterweight plate 11; the counterweight plate 11 is provided with multiple bolts, and the tail end of the bolts passes through the counterweight plate 11 and the rotating base 10 and is fixedly connected to the dial assembly 2.

[0044] By adopting the above technical solution, the counterweight plate 11 can submerge the entire aerator, ensuring that the dial assembly 2 is submerged in water at least halfway, but not completely. This allows the dial assembly 2 to generate circumferential water flow and better agitate the water when it moves, increasing the contact area between the water and air, thereby increasing the oxygen content of the water.

[0045] It should also be noted that the weight of the counterweight plate should be adjusted according to actual usage requirements.

[0046] The working principle of this utility model is as follows: When in use, the float box 4 uses the buoyancy of the water to float the entire aerator on the water surface; when working, the drive component 1 drives the deflector component 2 to rotate. When the deflector 21 rotates at high speed, the arc-shaped part 22 can generate water flow in the circumferential direction, while the upright part 23 can apply an additional vertical force to the water body during the rotation of the deflector 21, so that the water body not only makes circumferential motion on the plane, but also generates convection in the vertical direction, promoting the exchange of water between the upper and lower layers. Compared with the impeller of the traditional aerator, it can drive more water body to participate in the flow, and the range and effect of water diversion are better.

[0047] With the cooperation of the upright part 23 and the arc-shaped part 22 of the water wheel 21, the turbulence of the water will be increased when it rotates. The upright part 23 makes it easier for the water to be dispersed into more small water droplets and waves, which greatly increases the contact area between water and air. Moreover, the convection between the upper and lower water layers brought about by the upright part 23 can bring more water with low oxygen content at the bottom layer to the surface to contact the air, thereby improving the overall oxygenation efficiency.
