Description

Technical Field

[0001] This utility model relates to the field of oxygenation device technology, and in particular to an impeller-type aerator equipped with a permanent magnet synchronous motor. Background Technology

[0002] An aerator is a commonly used machine in aquaculture. It is a device that uses an electric motor or diesel engine to drive its working parts, which rapidly transfers oxygen from the air into the aquaculture water. The main purpose of this machine is to increase the oxygen content in the water to ensure that aquatic organisms such as fish do not suffer from oxygen deficiency.

[0003] In traditional aerators, the impellers are mostly made of plastic and are immersed in water. However, plastic impellers are prone to accumulating algae and moss when immersed in water for a long time, which affects the oxygenation effect and can easily lead to aging of the impeller and affect its service life.

[0004] Therefore, an impeller-type aerator equipped with a permanent magnet synchronous motor is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose an impeller-type aerator equipped with a permanent magnet synchronous motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An impeller-type aerator equipped with a permanent magnet synchronous motor includes a mounting plate on which the permanent magnet synchronous motor is fixedly connected. An aerator impeller is fixedly connected to the output end of the permanent magnet synchronous motor. The aerator also includes:

[0008] The telescopic rod is fixedly connected to the mounting plate;

[0009] A cover is fitted onto the mounting plate, and the cover is fixedly connected to the telescopic end of the telescopic rod;

[0010] An air pump is fixedly connected to the mounting plate, and an air outlet pipe is connected to the air pump. The air outlet end of the air outlet pipe is located above the oxygenating impeller.

[0011] To minimize gas leakage, preferably, an annular airbag is mounted on the mounting plate, and an outlet pipe is connected to the outlet end of the air pump, with the outlet end of the outlet pipe connected to the annular airbag.

[0012] To facilitate the contraction of the annular airbag, preferably, a pressure relief pipe is connected to the second air outlet pipe.

[0013] To facilitate the discharge of excess gas, preferably, the mounting plate is provided with an exhaust pipe, and an electronic valve is installed inside the exhaust pipe.

[0014] In order to guide water out during rainy weather, preferably, a water-guiding plate is fixedly connected to the mounting plate.

[0015] Preferably, multiple sets of support rods are fixedly connected to the mounting plate, and floating balls are connected to the support rods.

[0016] Compared with the prior art, this utility model provides an impeller-type aerator equipped with a permanent magnet synchronous motor, which has the following beneficial effects:

[0017] This invention, through the arrangement of a casing and an air pump, can enclose the aerator impeller in a relatively sealed space via the mounting plate and casing. Then, by injecting gas into the casing, the water level inside the casing is lowered, thereby placing the aerator impeller in a water-free space, reducing the growth of moss on the aerator impeller, and facilitating its long-term use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1:

[0024] Reference Figure 1-3An impeller-type aerator equipped with a permanent magnet synchronous motor includes a mounting plate 1, on which a permanent magnet synchronous motor 201 is fixedly connected. An aerator impeller 202 is fixedly connected to the output end of the permanent magnet synchronous motor 201. The aerator also includes: a telescopic rod 4 fixedly connected to the mounting plate 1; a cover 3 sleeved on the mounting plate 1 and fixedly connected to the telescopic end of the telescopic rod 4; an air pump 501 fixedly connected to the mounting plate 1, with an air outlet pipe 502 connected to the air pump 501. The air outlet end of the air outlet pipe 502 is located above the aerator impeller 202. An exhaust pipe 101 is provided on the mounting plate 1, and an electronic valve is installed inside the exhaust pipe 101. Multiple sets of support rods 203 are fixedly connected to the mounting plate 1, and float balls 204 are connected to the support rods 203.

[0025] When using this device, it is moved into the water. The floating ball 204 will then float the mounting plate 1 on the water, while the aerator impeller 202 is submerged. The permanent magnet synchronous motor 201 will then be activated to rotate the aerator impeller 202, thus aerating the water. After use, the telescopic rod 4 can be activated to lower the cover 3. The cover 3 will continue to descend along the outer wall of the mounting plate 1, thus... Figure 2 As shown, the aeration impeller 202 is covered, and at this time the bottom of the cover 3 is lower than the bottom of the aeration impeller 202. Then the air pump 501 can be started to inject gas into the cover 3 through the air outlet pipe 502. The injection of gas will cause the water in the cover 3 to be discharged, and then the gas will gradually fill the cover 3, thereby separating the aeration impeller 202 from the water and preventing the aeration impeller 202 from being in contact with water for a long time and producing a large amount of moss.

[0026] Meanwhile, excess gas can be prevented from moving upwards due to buoyancy exceeding gravity by opening the electronic valve in the exhaust pipe 101 at regular intervals.

[0027] Specifically, after the gas has been pumped in for a certain period of time, the air pump 501 can be turned off, so that the oxygenating impeller 202 is in the gas.

[0028] Specifically, a pressure sensor can be installed at the bottom of the mounting plate 1 to detect whether the oxygenating impeller 202 is in complete contact with the gas by changes in air pressure.

[0029] Alternatively, the air pump 501 can be set as an industrial heat pump, in which case the discharged gas is hot gas, which can dry the oxygenating impeller 202, further reducing the growth of moss caused by the humid environment.

[0030] Example 2:

[0031] Reference Figure 1-3An impeller-type aerator equipped with a permanent magnet synchronous motor is basically the same as that in Embodiment 1, but further: an annular air bag 6 is installed on the mounting plate 1, an air outlet pipe 503 is connected to the air outlet end of the air pump 501, the air outlet end of the air outlet pipe 503 is connected to the annular air bag 6, a pressure relief pipe 504 is connected to the air outlet pipe 503, and a water inlet plate 102 is fixedly connected to the mounting plate 1.

[0032] The permanent magnet synchronous motor 201 was chosen because of its compact structure, small size, and light weight, which makes it easy to float on water.

[0033] The annular airbag 6 provides a sealing effect, preventing gas leakage from affecting the drying of the oxygenating impeller 202 and ensuring that the oxygenating impeller 202 remains in constant contact with the gas.

[0034] Both the vent pipe 503 and the pressure relief pipe 504 are equipped with solenoid valves. The solenoid valves can control the pressure relief pipe 504 to discharge the gas in the annular airbag 6, which facilitates the discharge of water in rainy weather.

[0035] This invention, through the arrangement of the cover 3 and the air pump 501, can enclose the aerator impeller 202 in a relatively sealed space by the mounting plate 1 and the cover 3. Then, by injecting gas into the cover 3, the water level inside the cover 3 is lowered, thereby placing the aerator impeller 202 in a water-free space, reducing the growth of moss on the aerator impeller 202, and facilitating the long-term use of the aerator impeller 202.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
