Description

Technical Field

[0001] This invention relates to centrifugal fans, and more particularly to an integrated centrifugal fan. Background Technology

[0002] When a large amount of gas or powder needs to be extracted from the environment, a centrifugal fan with strong suction can be used. Centrifugal fans mostly adopt a volute structure, in which a high-speed motor and impeller are installed. The impeller draws in the gas or powder, and the centrifugal force generated inside the volute structure causes it to be discharged.

[0003] However, currently used centrifugal fans require selection based on environmental conditions. For example, environments containing hard impurities or powders, or those with corrosive gases or powders, often present a variety of conditions where these coexist, placing high demands on the centrifugal fan's adaptability. Currently, to meet the needs of different environments, the only solutions are usually to replace the centrifugal fan with a different type or its impeller. However, these methods require manual disassembly of the pipes and main unit, which is time-consuming, labor-intensive, and inefficient. Consequently, many centrifugal fans are not properly adapted for different environments, continuing to operate in these conditions, leading to reduced impeller lifespan and increased costs. Furthermore, the manual disassembly and maintenance of current centrifugal fan impellers is complex.

[0004] Therefore, it is necessary to develop an integrated centrifugal fan to solve the above problems. Summary of the Invention

The partitions 101 are respectively placed at the circular hole structures of the assembly frame 91. The outer periphery of the partitions 101 respectively mates with the inner wall of the circular hole structure of the assembly frame 91. The partitions 101 can also mate with the circular hole structure on the left side of the air guiding chamber 5. The partitions 101 are all made of magnetic shielding lead plate. An assembly shaft 102 is fixedly connected to the middle of each partition 101. The assembly shaft 102 has a keyway structure. The keyway structure of the assembly shaft 102 mates with the key structure of the main drive shaft 74. The assembly shaft 102 can be fitted onto the main drive shaft 74 by key engagement. At the moving shaft 74, a wind turbine 103 is fixedly connected to the right side of the partition 101. The wind turbine 103 has a high-speed blade structure, a wear-resistant blade structure, and a corrosion-resistant blade structure. By assembling the wind turbine 10 with different blade structures in the wind guide chamber 5, the wind guide chamber 5 can meet the requirements of drawing in different air under different environments. The mounting shaft 102 is fixedly connected from right to left to the left side of the partition 101 to the positioning ring 104, the mounting ring 105, and the magnetic ring 106. The positioning wheel group 83 can cooperate with the positioning ring 104, the mounting ring 92 can cooperate with the mounting ring 105, and the magnetic block 93 can magnetically attract the magnetic ring 106.

[0041] like Figures 15-16 As shown, the traction device 11 includes a fixed sleeve 111, a reversing motor 112, a traction shaft 113, a laser emission positioning module 114, and an electrically controlled magnetic ring 115. The fixed sleeve 111 is fixedly connected between the moving parts of the first electric slide rail 2. The reversing motor 112 is installed inside the fixed sleeve 111.

[0042] like Figure 3 and Figure 12As shown, it also includes a dust removal device 12, which includes a fourth electric slide rail 121, a dust removal chamber 122, an ultrasonic dust collector 123, and a dust collection assembly 13. The dust removal device 12 is located on the right side of the installation chamber 1 and is used to remove dust from an air guide device 10. The fourth electric slide rail 121 is fixedly connected to the front and rear positions of the lower right side of the installation chamber 1. The dust removal chamber 122 is fixedly connected between the moving parts of the fourth electric slide rail 121. The dust removal chamber 122 has a structure with an opening on the left side. The ultrasonic dust collector 123 is installed inside the dust removal chamber 122. A dust collection assembly is provided between the dust removal chamber 122 and the lower side of the connecting pipe 6. Component 13, the dust collection assembly 13, provides suction during operation through the air guide chamber 5 and the air guide device 10 installed inside it, so as to discharge the dust-containing gas in the dust removal chamber 122 through the dust removal assembly. During the operation of the impeller 103 of the air guide device 10, a lot of air dust will be attracted due to static electricity. This dust on the impeller 103 needs to be cleaned in time, otherwise it will easily affect the stability of the impeller 103 when rotating at high speed, and will also increase the power consumption of the drive motor 73. During the operation of the air guide chamber 5 and the air guide device 10 installed inside it, the first electric slide rail 2 can be controlled to run, so that the air required for dust removal is guided. Device 10 is positioned directly to the left of dust removal chamber 122. At this time, the fourth electric slide rail 121 can be controlled to move, causing the dust removal chamber 122 to move to the left, allowing it to enter the installation chamber 1 and the movable chamber 4, thus surrounding the air guide device 10. Simultaneously, the ultrasonic dust collector 123 can be activated, emitting ultrasonic waves to vibrate the impeller 103, dislodging dust adsorbed by electrostatic charge from its surface. At the same time, the dust collection assembly 13 can be activated, opening the airflow passage between the connecting pipe 6 and the dust removal chamber 122, allowing air to pass through the connecting pipe 6. Under negative pressure, the connecting pipe 6 can extract the air and dust contained in the dust removal chamber 122 through the dust suction component 13, thereby achieving dust removal of the impeller 103. Afterwards, the ultrasonic dust collector 123 and the dust suction component 13 can be turned off, and the fourth electric slide rail 121 can be controlled to move the dust removal chamber 122 to the right to reset. This can achieve automatic cleaning of the impeller 103, and can also achieve dust removal and cleaning without stopping the integrated centrifugal fan, further improving the integration and intelligence of the integrated centrifugal fan, further improving the working efficiency of the integrated centrifugal fan and reducing maintenance time and manpower.

[0043] like Figure 3 and Figure 12As shown, the dust collection assembly 13 includes a hose 131, an interconnecting pipe 132, and an electrically controlled valve 133. The hose 131 is fixedly connected to the right side of the dust collection chamber 122, and the interconnecting pipe 132 is fixedly connected to the right side of the hose 131. The electrically controlled valve 133 is fixedly connected between the interconnecting pipe 132 and the connecting pipe 6. The electrically controlled valve 133 is normally closed. Opening the electrically controlled valve 133 can open the connection between the connecting pipe 6 and the dust collection chamber 122.

[0044] Example 2, as Figures 1-17 As shown, the integrated centrifugal fan is assembled as follows: it is installed on a ground base through the bottom of the mounting compartment 1; the external extended suction pipe is connected to the right end of the connecting pipe 6, and the external extended suction pipe is placed in the environment where suction is required; the air outlet structure of the air guide compartment 5 is connected to the air exhaust pipe to form a centrifugal suction channel.

[0045] The process of assembling the air guide device 10 of the integrated centrifugal fan into the air guide chamber 5 is as follows: ① According to the environment of the gas to be extracted, control the operation of the second electric slide rail 3, so that the second electric slide rail 3 drives the movable chamber 4 to move up and down in the installation chamber 1, so that the air guide device 10 of one of the applicable environments is located on the left side of the air guide chamber 5; ② Start the first electric slide rail 2, so that the first electric slide rail 2 drives the traction device 11 to move to the right, so that the electrically controlled magnetic ring 115 contacts the magnetic ring 106 of the air guide device 10, so that the traction shaft 113 extends into the assembly shaft 102 of the air guide device 10. ③ Activate the electrically controlled magnetic suction ring 115, causing it to attract the magnetic ring 106, thus fixing the air guide device 10 to the traction shaft 113; ④ Continue to control the operation of the first electric slide rail 2, causing it to drive the traction device 11 and the air guide device 10 to move to the right, disengaging the assembly ring 105 and magnetic ring 106 of the air guide device 10 from contact with the mounting ring 92 and magnetic block 93 at that position on the assembly device 9; ⑤ Activate the laser emission positioning module 114 to emit a laser beam that irradiates the laser emitting plate on the main drive shaft 74, thus stimulating... The optical emission positioning module 114 receives the reflected laser light and simultaneously starts the reversing motor 112, causing the reversing motor 112 to adjust the angle of the air guide device 10 via the traction shaft 113, so that the angle of the assembly shaft 102 of the air guide device 10 is consistent with the angle of the main drive shaft 74; ⑥ Continue to control the operation of the first electric slide rail 2 to the end, so that the traction device 11 drives the assembly shaft 102 of the air guide device 10 to be fitted onto the main drive shaft 74, so that the air guide device 10 is inside the air guide chamber 5; ⑦ Control the operation of the third electric slide rail 81, so that the third electric slide rail 81 drives the moving frame 8 respectively. 2. Move the positioning wheel assembly 83 towards each other, so that the positioning wheel assembly 83 engages with the positioning ring 104 of the air guide device 10, making the positioning wheel assembly 83 and the positioning ring 104 serve as bearings for the rotation of the air guide device 10; ⑧ Control the electrically controlled magnetic suction ring 115 to disconnect the magnetic suction circuit, causing the electrically controlled magnetic suction ring 115 to demagnetize. At this time, the first electric slide rail 2 can be controlled to move to the left for reset, causing the electrically controlled magnetic suction ring 115, the reversing motor 112, and the traction shaft 113 to move to the left for reset; ⑨ Control the reversing motor 112 to drive the traction shaft 113 to perform a self-rotation reset process, so that the angle of the traction shaft 113 is reset. In this way, an air guide device 10 can be assembled in the air guide chamber 5.

[0046] The process of replacing the air guide device 10 in the air guide chamber 5 of the integrated centrifugal fan is as follows: ① Control the operation of the second electric slide rail 3, so that the second electric slide rail 3 drives the movable chamber 4 and the assembly device 9 to move up and down, so that an empty area of ​​the assembly device 9 is located on the left side of the air guide chamber 5; ② Turn off the drive motor 73, and wait for the drive motor 73 and the air guide device 10 it is assembled to stop rotating; ③ As described in "the process of assembling the air guide device 10 of the integrated centrifugal fan into the air guide chamber 5", the reversing motor 112 adjusts the angle of the traction shaft 113. ④ Control the third electric slide rail 81 to reset the moving frame 82 and the positioning wheel set 83, so that the positioning wheel set 83 is disengaged from the positioning ring 104 of the air guide device 10; ⑤ Start and control the first electric slide rail 2 to make the traction shaft 113 penetrate into the assembly shaft 102 of the air guide device 10, so that the electrically controlled magnetic ring 115 contacts the magnetic ring 106 of the air guide device 10, and at the same time start the electrically controlled magnetic ring 115. The suction ring 115 fixes the air guide device 10; ⑥ As described above in "the process of assembling the air guide device 10 of the integrated centrifugal fan into the air guide chamber 5", the reversing motor 112 and the traction shaft 113 drive the assembly shaft 102 of the air guide device 10 to rotate, so that the air guide device 10 is at a fixed angle; ⑦ Control the first electric slide rail 2 to move to the left and reset, so that the electrically controlled magnetic suction ring 115 attracts the air guide device 10 to move to the left, so that the assembly shaft 102 of the air guide device 10 disengages from the main drive shaft 74. ⑧ Control the first electric slide rail 2 to move the air guide device 10 to the left, so that the assembly ring 105 of the air guide device 10 enters the empty mounting ring 92, and the magnetic ring 106 of the air guide device 10 enters the empty magnetic block 93, so that the mounting ring 92 and the magnetic block 93 assemble and fix the air guide device 10; ⑨ Continue to control the first electric slide rail 2 to reset and run to the end, so that the traction shaft 113 disengages from the assembly shaft 102 of the air guide device 10.

[0047] The integrated centrifugal fan has three integrated variable extraction modes: one is to extract large amounts of clean air or powder; the second is to extract air or powder containing hard impurities; and the third is to extract corrosive gases or powder. Depending on the environment, an appropriate air guide device 10 can be installed within the air guide chamber 5. ① For extracting large amounts of clean air or powder, an air guide device 10 with a high-speed blade structure can be selected. The high-speed blade structure of the impeller 103 enables the drive motor 73 to operate at high speed, allowing the drive motor 73 to drive the impeller 10. 3. High-speed operation enables rapid and large-volume extraction and discharge of air and powder; ② For extracting air or powder containing hard impurities, a wear-resistant blade structure can be used for the air guide device 10 associated with the impeller 103. The wear-resistant blade structure of the impeller 103 prevents wear caused by high-speed impacts from hard impurities during air or powder extraction, improving the service life of the impeller 103 and the effective operating time of the integrated centrifugal fan; ③ For extracting corrosive gases or powders, a corrosion-resistant blade structure can be used for the air guide device 10 associated with the impeller 103. By automatically replacing the air guide device 10 with impellers 103 of different structures within the air guide chamber 5, the application environment of this integrated centrifugal fan can be broadened. Furthermore, for gas or powder extraction in the same environment, the operating state of the integrated centrifugal fan can be quickly switched as needed, improving its service life without the need for traditional centrifugal fan and pipe replacement, thus increasing the efficiency of gas or powder extraction from the environment.

[0048] The integrated centrifugal fan extracts gas or powder by: assembling a guide device 10 inside the guide chamber 5, turning on the drive motor 73, and driving the guide device 10 to rotate via the main drive shaft 74. This causes the guide device 10 to generate negative pressure through the guide chamber 5 from the connecting pipe 6, thereby drawing in gas or powder, which is then discharged from the outlet structure of the guide chamber 5.

[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
