Description

Technical Field

[0001] The utility model belongs to the technical field of oxygenators, relates to an oxygenator, and particularly relates to a new type of oxygenator. Background Art

[0002] An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be short of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the water from deteriorating and threatening the living environment of the fish.

[0003] In the prior art, the impeller of a general aerator is likely to suck aquatic organisms in the pond to the lower side of the impeller when rotating, causing damage to the impeller, and it is also likely to suck garbage in the water, so that the garbage will be entangled on the surface of the impeller, thereby affecting the working efficiency of the impeller. In addition, the water environment of aquaculture is generally closed, mainly ponds with a small water area. The fluidity of such water bodies is poor, resulting in the water area far away from the aerator relying on the water body's own flow or the slow diffusion of oxygen in the water to gradually increase the oxygen content, and this process is relatively long. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and provides a novel aerator which is easy to install and has a long service life.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of aerator, including an aerator body, the aerator body is composed of a skeleton, a motor and an impeller body, the motor shaft of the motor is connected to the impeller body and drives the impeller body to rotate, three float mechanisms are arranged outside the aerator body, characterized in that a diffusion mechanism with a filtering function is arranged at the lower end of the impeller body, the diffusion mechanism is composed of a filter cylinder and a plurality of diffusion plates, a connecting shaft for connecting to the impeller body is arranged in the filter cylinder, and the impeller body is driven to rotate by the rotation of the impeller body, a plurality of the diffusion plates are circumferentially arranged at the side end of the filter cylinder, a plurality of water holes for passing water are opened on the filter cylinder, a filter net for filtering impurities is arranged on the filter cylinder and at a position relative to each water hole, the connecting shaft and the bottom end of the filter cylinder are integrally formed, and the filter cylinder has a built-in space for the impeller body to rotate.

[0006] In the above-mentioned new type aerator, the impeller body is composed of a fixed part and a plurality of blades, the blades are circumferentially arranged on the fixed part and are all arranged in an inclined structure, the blades and the fixed part are arranged as an integrally formed structure, and the fixed part is provided with a plurality of openings.

[0007] In the above-mentioned new type aerator, a connecting flange for fixing the impeller body is fixedly arranged on the motor shaft, and the connecting flanges are respectively arranged at the front and rear ends of the impeller body. A fixing flange is arranged at the front end of the connecting shaft, and the fixing flange is fixedly connected to the connecting flange arranged at the rear end of the impeller body by fixing bolts.

[0008] Compared with the prior art, the novel aerator separates the area in the impeller body from the area in the filter cylinder, so that organisms or impurities in the external area will not affect the impeller body, and the diffusion plate arranged outside the filter cylinder rotates with the rotation of the impeller body, thereby accelerating the increase rate of the oxygen content in the watershed.

DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the novel aerator comprises an aerator body 1, which is composed of a skeleton 2, a motor 3 and an impeller body 4. The motor shaft of the motor 3 is connected to the impeller body 4 and drives the impeller body 4 to rotate. Three float mechanisms 5 are arranged outside the aerator body 1. The lower end of the impeller body 4 is provided with a diffusion mechanism 6 with a filtering function. The diffusion mechanism 6 is composed of a filter cylinder 7 and a plurality of diffusion plates 8. A connecting shaft 9 for connecting to the impeller body 4 is arranged in the filter cylinder 7, and the impeller body 4 is driven to rotate by the rotation of the impeller body 4. Several of the diffusion plates 8 are circumferentially arranged at the side end of the filter cylinder 7. Several water holes for passing water are opened on the filter cylinder 7. A filter screen 10 for filtering impurities is arranged on the filter cylinder 7 and at a position relative to each water hole. The connecting shaft 9 and the bottom end of the filter cylinder 7 are integrally formed, and the filter cylinder 7 has a built-in space 11 for the impeller body 4 to rotate.

[0014] To elaborate further, by providing a water hole and a filter net 10 on the filter cylinder 7, the filter cylinder 7 separates the impeller body 4 from the main flow domain, and impurities and organisms in the main flow domain cannot affect the rotation of the impeller body 4, thereby increasing the service life of the impeller body 4.

[0015] Preferably, the impeller body 4 consists of a fixing portion 12 and a plurality of blades 13, wherein the blades 13 are circumferentially arranged on the fixing portion 12 and are all arranged in an inclined structure, wherein the blades 13 and the fixing portion 12 are arranged as an integrally formed structure, and the fixing portion 12 is provided with a plurality of openings.
