Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, specifically a high-speed axial flow fan. Background Technology

[0002] Axial flow fans are a common type of fan used in industrial and mining enterprises. They mainly consist of a fan impeller and a casing. While their structure is simple, the specifications are very demanding. They are typically used in applications requiring high flow rates but low pressure, and can be used for ventilation in factories, warehouses, offices, and residences. However, current axial flow fans suffer from the following drawbacks: the motor, impeller, and other components are directly mounted inside the casing, which is usually a ring-shaped or rectangular protective cover. This makes repairs difficult when the motor, impeller, or motor shaft is damaged or malfunctions. Workers must reach inside the casing to inspect these components, making it impossible to remove them for maintenance, which is extremely inconvenient. Therefore, this invention proposes a high-speed axial flow fan to address these shortcomings. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-speed axial flow fan. By mounting the motor on a mounting plate, which is fixed to a T-shaped plate, and detachably assembling the T-shaped plate onto the outer cylinder, and locking it in place using a positioning component, the fan can be easily disassembled and assembled. This allows for the quick removal of components such as the T-shaped plate, mounting plate, and motor, facilitating the maintenance and repair of these parts and solving the problem of inconvenient inspection and maintenance of high-speed axial flow fans at present.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A high-speed axial flow fan includes an outer cylinder. Two symmetrically distributed T-shaped grooves are formed on the inner wall of the outer cylinder, extending to the outer side of the outer cylinder. T-shaped plates are fitted to both T-shaped grooves of the outer cylinder, and a mounting plate is fixedly connected between the two T-shaped plates. A motor is mounted on one side of the mounting plate, and an impeller is fixed on a rotating shaft coaxially arranged on one side of the motor. A positioning component for locking and positioning the T-shaped plates is provided on one side of the outer cylinder. The positioning component includes a positioning ring threaded onto the outer cylinder and a positioning protrusion integrally formed on one side of the positioning ring, the positioning protrusion abutting against one side of the T-shaped plate.

[0006] Furthermore, the outer wall of the outer cylinder is provided with a first external thread, and the inner wall of the positioning ring is provided with a first internal thread, the first internal thread being adapted to the first external thread.

[0007] Furthermore, the outer wall of the positioning ring is provided with an array of anti-slip protrusions.

[0008] Furthermore, the air inlet end of the outer cylinder is threadedly connected to an annular plate, and a filter plate is provided on an annular seat integrally formed on one side of the annular plate, and a protruding edge is provided on the other side of the annular plate, which abuts against the outer cylinder.

[0009] Furthermore, a positioning plate for locking and positioning the filter plate is provided on the inner wall of the annular plate. One side of the positioning plate abuts against the filter plate, and a fixing seat is provided on the other side of the positioning plate. The fixing seat is fixed to the protruding edge with bolts.

[0010] The positioning plate is equipped with an arc-shaped flow guide surface.

[0011] Furthermore, the inner wall of the outer cylinder is provided with a second internal thread, and the outer wall of the annular plate is provided with a second external thread that matches the second internal thread; a base is fixedly connected to the bottom of the outer cylinder.

[0012] Compared with the prior art, this utility model provides a high-speed axial flow fan, which has the following beneficial effects:

[0013] This invention features a T-shaped groove on the inner wall of the outer cylinder, with a T-shaped plate fitted into the groove and a mounting plate fixed to it. The motor of the high-speed axial flow fan is mounted on this mounting plate, driving the rotating shaft and impeller to achieve the exhaust function of the high-speed axial flow fan. A positioning component is provided on one side of the outer cylinder to lock and position the T-shaped plate, controlling its assembly and disassembly. If necessary, the positioning component can be removed, allowing the T-shaped plate, mounting plate, and motor to be taken out for direct inspection and maintenance. This is very convenient, facilitating the cleaning of dust from the impeller and the inspection and maintenance of the motor.

[0014] This utility model features an annular plate at the air inlet end of the outer cylinder, with a filter plate mounted on an annular seat on one side of the annular plate. The filter plate is locked and positioned by a positioning plate, enabling it to filter the air at the air inlet end and effectively reduce the impact of dust.
