Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to a noise-reducing magnetic suspension fan structure of a sewage station. Background Art

[0002] The magnetic levitation blower is equipped with a magnetic levitation controller, which generates a magnetic field through electric current to achieve the suspension of the rotating shaft. The high-speed motor generates a frequency-controlled alternating current through a variable frequency power supply, which is input into the alternating magnetic field generated by the motor stator, driving the rotating shaft to rotate at high speed. The blower impeller drives the air to enter from the air inlet of the volute. The air becomes a gas with a certain flow rate and pressure under the guidance and pressurization of the volute, and finally blows out from the air outlet of the volute. However, due to the poor sound insulation effect of ordinary magnetic levitation blower cabinets, the noise generated by the blower during actual operation is very high, which has a great adverse effect on surrounding personnel and the surrounding environment. The main engine speed of magnetic levitation blowers and magnetic levitation compressors is 30,000 r / min, and the noise is about 110dB, which is very harsh. People in this environment may temporarily lose hearing (deafness) for one minute. Therefore, noise reduction and sound insulation treatment is required in the cabinet to reduce the noise to below 80dB (the upper limit of ordinary people's hearing comfort). The commonly used method is to install a sound-absorbing board inside the cabinet to achieve the purpose of noise reduction. However, the existing sound-absorbing board is difficult to install and use. There are still some shortcomings: the traditional way to reduce noise for blowers is to install a single layer of sound insulation cotton on the inner wall of the blower, such as application number: CN202320098138.4 A noise reduction structure for a magnetic levitation blower, including reinforcing ribs, a soft sound insulation layer and a hard sound insulation layer, a number of transversely arranged reinforcing ribs and longitudinally arranged reinforcing ribs are fixed to the inner wall of the blower by a first fixing member, and a soft sound insulation layer is provided in the accommodation grid formed by adjacent transversely arranged reinforcing ribs, longitudinally arranged reinforcing ribs and the inner wall, and a hard sound insulation layer is provided on the other side of the soft sound insulation layer, and the hard sound insulation layer is fixed to the reinforcing ribs by a second fixing member, and the second fixing member is compatible with the first fixing member. The above-mentioned structural arrangement has the problem of poor noise reduction effect when used in the magnetic levitation blower structure of a sewage station. Utility Model Content

[0003] The utility model aims to provide a noise-reducing magnetic levitation fan structure for a sewage station, so as to solve the problem that the noise-reducing muffler plate of the existing magnetic levitation fan structure for a sewage station is usually directly installed on the inner wall of the cabinet, resulting in poor noise reduction effect.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a noise-reducing magnetic levitation fan structure for a sewage station, comprising a magnetic levitation fan structure for the sewage station and a noise-reducing body structure arranged in the magnetic levitation fan structure for the sewage station, the magnetic levitation fan structure for the sewage station comprising a fan outer frame body and fan components arranged in the fan outer frame body, the noise-reducing body structure comprising a noise-reducing and sound-insulating connecting plate assembly in the inner surface of the fan outer frame body, the noise-reducing and sound-insulating connecting plate assembly comprising an external connecting frame structure, a sound-insulating material body structure arranged in the external connecting frame structure and a fixing member group structure arranged outside the sound-insulating material body structure.

[0005] The external connection frame structure includes an upper frame connection structure and a lower frame connection structure with the same structure. The upper frame connection structure includes an external fixing seat, side fixing seats arranged at both ends of the external fixing seat, a group of side shock-absorbing connecting seats arranged at intervals on the upper edge of the upper fixing seat, and a central connecting fixing seat arranged in the middle of the upper end of the upper fixing seat.

[0006] The sound insulation material body structure includes a central sound insulation cotton body, a silicone layer arranged outside the central sound insulation cotton body, a glass fiber cloth layer arranged outside the silicone layer, and a sound insulation connecting plate body arranged outside the glass fiber cloth layer. Noise reduction protrusions are evenly distributed on the sound insulation connecting plate body.

[0007] A locking member group is arranged on the outer side of the external fixing seat.

[0008] The upper frame connection structure and the lower frame connection structure are connected with an edge blocking block.

[0009] The fixing component group structure comprises an external fixing truss body group arranged outside the sound insulation material body structure and connected to the external connecting frame structure, and a middle connecting barrier block arranged between the external fixing truss body groups.
