[0016] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.
[0017] See also Figures 1 to 3 The utility model relates to a flow guide component for reducing the wind resistance of a dust removal duct, comprising a duct component 6 and a sheet metal box 5. The air inlet end of the duct component 6 is mounted on the sheet metal box 5. The duct component 6 comprises a flow guide cover 1, a front pipe 2, a rear pipe 3 and a spiral blade 4. The flow guide cover 1 is detachably mounted on one end of the front pipe 2, and the rear pipe 3 is mounted on the other end. One end of the rear pipe 3 forms a contracted end, and the other end forms a flared end. The contracted end of the rear pipe 3 is connected to the front pipe 2, and the flared end of the rear pipe 3 forms an air outlet end; one end of the flow guide cover 1 is hexagonal, and the other end is circular, and the air inlet end of the duct component 6 is formed at the flow guide cover 1; spiral blades 4 arranged along the length direction of the front pipe are installed inside the front pipe 2.
[0018] Based on the arrangement of the air deflector, the front pipe and the rear pipe, the following advantages are achieved:
[0019] Efficient airflow guidance: The air deflector 1 is located at the air inlet end of the air duct assembly 6, effectively capturing and guiding the airflow to smoothly enter the front pipe 2, avoiding turbulence caused by direct airflow, and significantly reducing wind resistance in the initial stage.
[0020] Spiral blades optimize flow state: The spiral blades 4 arranged along the length direction inside the front pipe 2 continuously push the airflow to flow stably along the axial direction through its spiral structure, reducing the vortex and separation of the airflow, further reducing the friction resistance inside the air duct, and improving the airflow transmission efficiency.
[0021] Gradual contraction and expansion design: one end of the rear tube 3 is a contracted end connected to the front tube 2, and the other end is a flared end to form an air outlet. Such a gradual contraction and expansion structure can smoothly transition the air flow speed, effectively avoid energy loss of the air flow at the point where the pipe diameter changes, and reduce local wind resistance.
[0022] Modular design facilitates maintenance: The detachable connection between the front pipe 2 and the air deflector 1, as well as the overall modular structure, make the components easy to disassemble and assemble, convenient for daily cleaning and maintenance, and also convenient for adjusting the component configuration according to actual working conditions, thereby improving the flexibility and adaptability of the system.
[0023] Energy saving and emission reduction: The reduction of wind resistance means that the power consumption required at the same air volume is reduced, thereby achieving the purpose of energy saving and emission reduction, and can significantly reduce operating costs in the long run.
[0024] The deflector 1 is in the shape of a regular hexagon as a whole. Compared with a circular or other shape, the deflector 1 of the regular hexagon provides more edge contact points, and can form a more stable sealing interface when connected with the front pipe by a buckle, effectively preventing air leakage and ensuring the air tightness and work efficiency of the dust removal. The design of the deflector of the regular hexagon minimizes the volume while being conducive to layout in a limited space, especially in a compact industrial environment. This design can optimize the layout and save space resources.
[0025] A buckle is installed on the front pipe where the air deflector 1 and the front pipe 2 meet, and the air deflector and the front pipe are connected together by the buckle. The buckle connection method simplifies the assembly process of the air deflector and the front pipe, and can be quickly installed or disassembled without additional tools, which is convenient for adjusting the direction of the air deflector on site or performing regular cleaning and maintenance, thereby improving the convenience and efficiency of operation.
[0026] The utility model also relates to a flow guiding device, comprising a plurality of flow guiding components for reducing the wind resistance of the dust removal air duct, wherein the flow guiding covers of two adjacent flow guiding components are closely arranged to form a honeycomb structure.
[0027] The working principle of the utility model is:
[0028] Airflow introduction: At the beginning of work, the dust-containing gas first enters the guide assembly through the sheet metal box 5. The guide cover 1 is designed as a regular hexagon, which not only increases the effective area of the air inlet, but also distributes the incoming airflow more evenly, avoiding turbulence and increased wind resistance caused by concentrated impact of airflow.
[0029] Airflow acceleration and guidance: After passing through the deflector 1, the airflow enters the front pipe 2. The spiral blades 4 installed inside the front pipe 2 are arranged along the length of the pipe. As the airflow passes through, the spiral blades 4 can exert a thrust along the axial direction of the pipe on the airflow, causing the airflow to flow steadily and quickly along the center line of the pipe. This design reduces the lateral movement and vortex of the airflow, thereby effectively reducing wind resistance.
[0030] Gradual contraction and expansion to reduce drag: The airflow then enters the rear pipe 3, which is designed with a contracted end connected to the front pipe 2 at one end and a flared end at the other end to form an outlet. The structure of the contracted end can smoothly transition when the airflow turns, reducing eddy currents and energy losses; while the flared end gradually expands the cross-sectional area of the pipe when the airflow is output, gradually reducing the airflow speed, which helps to smooth the release of the airflow and further reduce the wind resistance and noise at the outlet.
[0031] Sealing and stability: The air deflector 1 and the front pipe 2 are connected by snap-fit. This design not only ensures the stability and sealing of the connection, but also facilitates quick disassembly and maintenance, thereby improving the flexibility of the system.
[0032] In summary, the guide component achieves effective control and management of the airflow through the airflow introduction design, the guiding and accelerating effect of the internal spiral blades, and the gradually contracting and expanding structure of the rear pipe, which greatly reduces the wind resistance inside the air duct, improves the efficiency and energy efficiency of the dust removal system, and ensures the stable operation of the system and a low noise level.
[0033] In particular, the front end of the air deflector is a regular hexagon, and all the air duct components are in close contact when in use, forming a honeycomb structure, which reduces wind resistance.
[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
