Description

Technical Field

[0001] This utility model belongs to the field of axial flow fan technology, and in particular relates to a high-flow-rate, high-pressure axial flow fan. Background Technology

[0002] Axial flow fans are core equipment in industrial ventilation, air delivery, and environmental control systems, and their performance directly affects system operating efficiency. Traditional high-flow-rate, high-pressure axial flow fans typically employ an integrated design, with the pressurization and air delivery units fixed inside the casing. This design has significant drawbacks in long-term use: when a single component (such as the impeller, motor, or sealing structure) fails, the entire fan must be disassembled for repair or replacement, resulting in long downtime and high maintenance costs. Furthermore, high-pressure operating conditions demand stringent structural stability, and the fixed installation of traditional fans cannot simultaneously meet the requirements for rapid disassembly and assembly with structural compactness. Some improved fans attempt to adopt a split structure, but the connection methods between components are complex, and disassembly and assembly can easily cause casing deformation or seal failure, affecting the fan's aerodynamic performance. Therefore, there is an urgent need for an axial flow fan structure that can ensure stable high-pressure output while enabling rapid separation and maintenance of key components, thus addressing the technical pain points of low maintenance efficiency and poor structural adaptability in existing technologies.

[0032] like Figure 1-5 As shown, a high-flow-rate, high-pressure axial flow fan includes a housing 101, a pressurizing component, and an air supply component 103. Both the pressurizing component and the air supply component 103 are located inside the housing 101, with the pressurizing component at one end of the air supply component 103. Connectors are provided on the inner wall of the housing 101, with two sets of connectors located at both ends of the housing 101. The pressurizing component and the air supply component 103 are respectively connected to the two connectors, and the pressurizing component and the air supply component 103 can move along the connectors and be moved out from both ends of the housing 101.

[0033] Specifically, the pressurization component includes a mounting block 104, a first connecting rod 109, a motor 105, a connector 106, and several fan blades 107. The motor 105 is mounted on the mounting block 104. Both the connector 106 and the mounting block 104 are cylindrical structures. The connector 106 is connected to the output shaft of the motor 105. The fan blades 107 are evenly arranged on the connector 106 in a circular pattern. Multiple sets of the first connecting rod 109 are provided, and multiple sets of the first connecting rod 109 are evenly arranged on the mounting block 104 in a circular pattern. The air supply component 103 has the same structure as the pressurization component. The pressurization component pushes the airflow to the air supply component 103, and the air supply component sends out the airflow, performing secondary pressurization on the airflow to ensure the air pressure of the airflow.

[0034] The first connecting rod 109 is provided with a slider 118. The first connecting rod 109 and the slider 118 cooperate to form a T-shaped structure. The connecting component is a connecting block 108 provided on the inner wall of the outer shell 101. The connecting block 108 is provided with a connecting groove corresponding to the first connecting rod 109, that is, the connecting groove is also a T-shaped structure. The connecting block 108 is fixed to the inner wall of the outer shell 101 by screws, and the connecting block 108 can be easily disassembled and assembled.

[0035] Furthermore, the slider 118 is provided with a movable groove, and a fixed block 117 is provided in the movable groove. The inner wall of the connecting groove is provided with a fixed groove corresponding to the fixed block 117. The connecting block 108 is provided with a through cavity communicating with the fixed groove, and a fixed screw 113 is provided in the through cavity. The fixed block 117 is provided with a threaded hole corresponding to the fixed screw 113.

[0036] The first connecting rod 109 has a movable cavity, the fixed block 117 has a second connecting rod 110, the second connecting rod 110 has a connecting plate 111, the connecting plate 111 is located in the movable cavity, the connecting plate 111 has a push block 112, and the push block 112 passes out from the movable cavity.

[0037] When connecting the mounting block 104, after the first connecting rod 109 is aligned with the connecting groove, the first connecting rod 109 is pushed into the connecting groove. The slider 118 enters the connecting groove and moves along the connecting groove to one end of the connecting groove. The fixing block 117 moves to the top position of the fixing groove. The fixing block 117 automatically falls out of the movable groove and inserts into the fixing groove to initially fix the slider 118 in the connecting groove. Then, the fixing screw 113 is turned into the threaded hole, so that the fixing block 117 is fixed in the fixing groove, completing the installation of the mounting block 104. When disassembling the mounting block 104, the fixing screw 113 is turned out of the threaded hole, pushing the push block 112 to move. The push block 112 drives the connecting plate 111 to move, and the fixing block 117 rises from the fixing groove, so that the slider 118 can be removed from the connecting groove, completing the disassembly of the mounting block 104.

[0038] The slots on the connecting blocks 108 at both ends of the housing 101 are arranged back to back, and the slots on both connecting blocks 108 are arranged facing the outside of the housing 101, so that the pressurizing component and the air supply component 103 can be quickly and easily disassembled and assembled.

[0039] Furthermore, the first connecting rod 109 is provided with a cavity, and the mounting block 104 is provided with a mounting groove. The cavity communicates with the mounting groove, and a winding roller 115 is provided in the cavity. A connecting shaft 114 is provided in the cavity, and the winding roller 115 is sleeved on the connecting shaft 114, so that the winding roller 115 is rotatably connected to the connecting shaft 114. A cover plate 116 is provided on the cavity, and a first extension plate 119 is provided on the side wall of the cover plate 116. A second extension plate 120 is provided on the first connecting rod 109, and the first extension plate 119 is fixed to the second extension plate 120 by screws.

[0040] After the motor 105 is installed on the mounting block 104, the cover plate 116 is opened to remove the winding roller 115. The excess power wire of the motor 105 is wound around the winding roller 115, and then the winding roller 115 is put onto the connecting shaft 114. The power wire of the motor 105 is stored in the cavity so that the power wire is connected to the contact terminal in the cavity. Then the cover plate 116 is connected to the first connecting rod 109 to close the cavity and store the power wire of the motor 105.

[0041] Furthermore, a filter cover 102 is connected to one end of the housing 101. The filter cover 102 is installed on the housing 101 by a threaded connection. The filter cover 102 is used to filter the airflow entering the housing 101, reducing the amount of dust entering the housing 101. The threaded connection of the filter cover 102 makes it easier to replace and maintain the filter cover 102.
