Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a fan with the air outlet in the middle. Background Technology

[0002] A blower is a general-purpose machine used to transport and change the energy of gas, widely used in various sectors of the national economy. Based on the different outlet pressure levels, blowers can be divided into ventilators, blowers, and compressors. A blower consists of components such as an impeller, collector, louvers, opening mechanism, motor, pulley, air inlet shroud, inner frame, and volute. The impeller is the core component of the blower, and its design and type (such as backward, radial, and forward) affect the blower's efficiency and noise level. In the heavy oil combustion process, the blower provides sufficient oxygen for combustion, while the motor in the blower is only used to power the blower. During heavy oil combustion, the blower's airflow is needed to rotate the rotor in the heavy oil atomization device, but this process is inefficient, resulting in low motor utilization.

[0003] Therefore, it is necessary to design a fan with the air outlet in the middle. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a fan with a central air outlet, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A fan with a central air outlet includes a base, a motor, and a housing. The motor is mounted directly above the base, and the housing is mounted on one side of the base. An impeller is mounted in the middle of the housing. The drive end of the motor is connected to the impeller through the housing via a linkage. A synchronous belt is connected to the linkage. An air inlet is provided on the side of the housing away from the motor. An annular air duct is provided on the outer side of the housing. The air outlet of the annular air duct is located in the center of the top of the housing. The air outlet and the linkage are on the same horizontal plane.

[0006] Furthermore, the housing is disc-shaped, and the air inlet is circular and positioned directly opposite the impeller.

[0007] Furthermore, two reinforcing ribs are provided at the connection between the base and the housing.

[0008] Furthermore, the reinforcing rib is triangular in shape, with its bottom fixedly connected to the top of the base and its sides fixedly connected to the housing.

[0009] Furthermore, the annular air duct is connected to the inside of the casing, and its input end corresponds to the output end of the impeller.

[0010] Compared with the prior art, the fan with the air outlet in the middle provided by this utility model has the following beneficial effects:

[0011] This utility model discloses a fan with the air outlet in the middle, in which the starting point of the annular air duct is located in the center of the casing. When the fan starts, it can provide sufficient oxygen to the heavy oil combustion equipment along the pipe in the vertical direction of the linkage. At the same time, the motor in the fan can drive the synchronous belt through the linkage, and the synchronous belt can drive the rotor in the heavy oil atomizing equipment to rotate, thereby accelerating the atomization process. When the motor starts, it can not only enable the fan to provide sufficient oxygen for heavy oil combustion, but also drive the rotor in the heavy oil atomizing equipment to rotate, thereby improving the utilization efficiency of the motor.
