Embodiment Construction
[0046] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0047] The specific embodiment of the fan module of the present invention includes a centrifugal fan module 1 and an air boost injection module 2, the two modules are in different forms, and the air flow sent by the centrifugal fan module 1 is delivered to the air boost injection module 2 Afterwards, the pressurized jet is ejected and drives the surrounding air to flow, increasing the air volume of the fan module.
[0048] Wherein, the structure of the centrifugal fan module 1 is as follows: Figure 1-2 As shown, it includes a square fan enclosure 10. A centrifugal fan 11 is fixedly installed in the fan enclosure 10. The centrifugal fan 11 includes a motor 110 and an impeller 111. The impeller 111 includes 6-32 circular arc backward blades. The motor 110 is fixedly connected to one side panel of the square housing 10 by bolts, and the panel is provided ...

The invention relates to a centrifugal fan module, an airflow pressurizing injection module and a fan unit. Specifically, a centrifugal fan is installed in a fan closed shell of the centrifugal fan module of the fan unit, a fan air inlet corresponding to the axial direction of the centrifugal fan is formed in the fan closed shell, and fan air outlets corresponding to the radial direction of the centrifugal fan are formed in the fan closed shell; an annular pressurizing cavity is formed in an annular pressurizing shell of the airflow pressurizing injection module, an annular injection gap is formed in the annular pressurizing cavity and located in an inner hole of the annular pressurizing shell, and a radial ventilation opening communicating with the annular pressurizing cavity is further formed in the annular pressurizing shell; and the airflow pressurizing injection modules are spliced to the positions of all the fan air outlets of the centrifugal fan module, and the fan air outlets of the centrifugal fan module communicate with the radial ventilation openings of the corresponding airflow pressurizing injection modules in a butt joint mode. The fan part structure and the airflow pressurizing injection part structure of the fan unit are independent modules, so that the manufacturing and assembling requirements are reduced, the transportation is relatively convenient, and the maintenance and repair are convenient.
Description
technical field [0001] The invention relates to a centrifugal fan module, an airflow pressurized injection module and a fan module. Background technique [0002] As an important supporting equipment in industry, fans are widely used in the fields of electric power, cement, petrochemical, coal, mining and environmental protection. With the requirements of energy saving, consumption reduction and noise reduction, fans have also been continuously innovated. For example, the Chinese utility model patent with the authorized announcement number CN203685690U discloses a turbocharged blower fan. A centrifugal fan is installed inside, and the air supply chamber also has an annular pressurized chamber. The annular pressurized chamber has an annular narrow and long air outlet to form an airflow booster injection structure that can blow out the air at high speed. The high-speed airflow discharged from the narrow and long air outlet can Drive the air flow in the middle of the annular ai...
