Abstract
Description
Technical Field
[0001] This utility model relates to the field of axial flow fan technology, and in particular to a combined axial flow fan. Background Technology
[0002] As a core piece of equipment in the fields of ventilation, heat exchange and purification, combined axial flow fans are widely used in industrial plants, warehousing and logistics and electronic computer rooms. They need to meet the requirements of air volume delivery, airflow purification and temperature regulation at the same time. Through the mechanical combination of multi-functional components, they can achieve "multi-effect treatment with one air supply". Compared with single-function axial flow fans, they can reduce the equipment footprint and the complexity of system piping connections.
[0003] Existing technologies suffer from low integration of functional components in traditional equipment, often employing fixed welded housings. Filter and heating modules cannot be independently disassembled, requiring the entire fan to be disassembled when replacing filter media or repairing heating elements, resulting in long processing times and reduced work efficiency. Existing technologies use "sliding rail filter modules" to connect the filter media frame to the fan housing via sliding rails, enabling pull-out replacement of the filter media and shortening maintenance time. However, sliding rail filter modules only solve the problem of disassembling a single component; the heating module remains a fixed structure, failing to achieve full module detachability and resulting in insufficient overall flexibility. Utility Model Content

Slider blocks 202 are slidably connected to the housing 1.
[0033] Specifically, during installation, first align the screws 204 on the base 206 with the holes on the filter plate 201 and insert them. Then tighten the nuts 205 to securely fix the base 206 onto the filter plate 201. The heating rod 207 is pre-fixed on the base 206. When the temperature needs to be adjusted, the heating rod 207 can be turned on directly. Pick up the filter plate 201, align the slider 202 on it with the groove 203 on the outer casing 1, and move the filter plate 201 forward along the groove 203 to gradually assemble it onto the outer casing 1. Then rotate the filter plate 201 clockwise to achieve quick assembly and disassembly of the filter plate 201 and the heating component, providing convenience for subsequent replacement and cleaning operations.
[0034] Reference Figure 4 , Figure 5 and Figure 6The rotating mechanism 3 includes fixed rods 301, with multiple fixed rods 301 respectively installed on the middle of the left and right sides of the outer casing 1. Rotating shafts 302 are threadedly connected to the middle of the left and right sides of each fixed rod 301. A drive assembly 303 is installed on the middle of the lower side of the outer casing 1. A bracket 5 is fixedly connected to the fixed rods 301, and the outer casing 1 is rotatably connected to the rotating shafts 302. The drive assembly 303 includes a motor 3031, model GV28-0.75KW-10S, which is a combination of an AC variable frequency motor and a planetary reducer. The frequency converter adjusts the speed and stabilizes the output torque. Motor 3031 is installed on the bottom right side of the housing 1. Gear 3032 is fixedly connected to the output end of motor 3031. Rack 3033 is fixedly connected to the bottom of the outer wall of housing 1. Rack 3033 meshes with gear 3032. Support base 3034 is fixedly connected to the bottom of motor 3031. Support plate 3035 is fixedly connected to the top of support base 3034. Support plate 3035 is rotatably connected to gear 3032. Support plate 3035 is fixedly connected to bracket 5.
[0035] Specifically, starting motor 3031 drives gear 3032 to rotate. The rotation of gear 3032 drives rack 3033 to swing back and forth around rotating shaft 302. The operator can adjust the swing direction of rack 3033 according to actual needs. Fixing rod 301 can limit the lateral movement of housing 1 and prevent housing 1 from deviating during equipment operation, thereby improving the stability of the overall structure. Support base 3034 and support plate 3035 cooperate with each other to support motor 3031, ensuring that motor 3031 remains stable during operation and ensuring reliability.

The speed is adjusted by the frequency converter and the output torque is stable. A fan blade 10 is fixedly connected to the output end of the motor 2 9.
[0037] Specifically, the inner wall of the outer casing 1 is equipped with a protective net 4, the bottom of the support frame 5 has a frame 6, and the bottom of the frame 6 is equipped with wheels 7, which facilitates flexible adjustment of the equipment position. When the motor 2 9 is started, the motor 2 9 drives the fan blade 10 to rotate. The fan blade 10 generates wind power during rotation, which can meet the needs of ventilation, heat exchange and purification in the production environment. The support frame 2 8 provides stable support for the motor 2 9, ensuring that the motor 2 9 remains stable when driving the fan blade 10, and avoiding the impact of vibration on the wind power output effect.
[0038] Working principle: Align the screws 204 on the base 206 with the holes on the filter plate 201 and install them. Then tighten the nuts 205 to fix the base 206 on the filter plate 201. The base 206 is fixed with a heating rod 207. When temperature adjustment is required, the heating rod 207 can be turned on. Then pick up the filter plate 201, align the slider 202 with the groove 203 on the outer shell 1, and move it forward to install the filter plate 201 on the outer shell 1. Rotate it clockwise to allow the filter plate 201 to be quickly disassembled from the heating component for easy replacement and cleaning.
[0039] The motor 3031 is started, which drives the gear 3032 to rotate. Its rotation causes the rack 3033 to swing back and forth around the rotating shaft 302. The direction can be adjusted as needed. The fixed rod 301 can limit the lateral movement of the outer shell 1 and improve the overall stability. The support base 3034 and the support plate 3035 can support the motor 3031 and provide stability for its working state. The motor 9 is started, which drives the fan blade 10 to rotate and generate wind power to meet the needs of ventilation, heat exchange and purification in the production environment. The bracket 8 provides stable support for the operation of the motor 9.
