[0003] Patent No. ZL200710051289X, "Air Smoke Centrifugal Purification Device and Method for Making Rotating Filter Disc thereof", discloses a method for making a centrifugal purification device for air smoke and its matching filter disc. The purification device mainly relies on a rotating filter disc installed on the motor output shaft to cut and separate oil smoke and dust. The spokes on the rotating filter disc are made of a filter wire with a diameter of 0.1 to 0.2 mm, which rotates relatively in the circumferential direction between the outer rim and the shaft sleeve and is wound back and forth in the diameter direction. The winding of the filter wire of the filter disc will form an overlap of the filter wire at several positions, making the entire filter disc have an uneven density of filter wires. The small diameter of the filter wire will also affect its cutting and separation ability. The long use time will cause the filter wire to deform, reducing the overall purification efficiency of the purifier. The center disc in the middle of the filter disc and the connected supporting ribs are easily attached to the oil smoke when in contact with the oil smoke, reducing the self-cleaning ability of the purifier.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] like Figures 1 to 3 As shown, the present invention provides a pipeline oil fume purification device with self-cleaning ability, including an outer shell bracket 3, a motor 4 is fixedly installed on one side of the outer shell bracket 3, a coupling 5 is fixedly installed on the output end of the motor 4, a shaft body 6 is fixedly installed on one end of the coupling 5, a fan blade 2 is rotatably connected inside the outer shell bracket 3, a center column 7 is fixedly installed on the surface of the shaft body 6, and the shaft body 6 is located at the center of the center column 7, a filter disk is fixedly installed on one end of the shaft body 6, two upper and lower outer rims 1 are arranged inside the filter disk, and the shaft body 6 and the fan blade 2 are both located inside the filter disk, a radial filter composed of filter wire is arranged between the outer rim 1 and the center column 7, a rectifying cone 8 is fixedly installed on one side of the outer shell bracket 3, an air pipe 9 is fixedly installed on the surface of the rectifying cone 8, and one end of the air pipe 9 is connected to a steam generating device.
[0023] The above scheme is adopted: the operator knots and fixes the head end of the filter wire at A0 on the edge of the outer rim 1, then tightens the filter wire so that it is close to the center column 7 and one side of the shaft body 6 and extends straight downward, and then continues to tighten the filter wire so that it is projected from the back through B0 to C0 on the edge of the outer rim 1 on the other side, and is close to the center column 7 and one side of the shaft body 6 and extends straight upward. At this time, the outer rim 1 is rotated by an angle, and the filter wire is then wound to A0 so that it is projected to another point D1 adjacent to D0 on the edge of the outer rim 1 on the other side, and then continues to tighten the filter wire so that it passes through the projection A1 of D1 and extends straight downward, and is wound to B1 adjacent to the symmetrical point B0 on the edge of the outer rim 1, and then repeats this operation until the filter wire is evenly wound and woven along the circumferential direction of the outer rim 1 to form a radial radial filter, and finally the tail end of the filter wire is wound and knotted and fixed at the initial point A0 on the edge of the outer rim 1;
[0024] Next, the entire device can be installed at the specified position, and then the motor 4 can be driven so that its output end drives the coupling 5 to rotate, the coupling 5 will drive the shaft 6 to rotate, the shaft 6 will drive the center column 7 and the fan blades 2 to rotate, and during the rotation of the fan blades 2, the direction of the oil fume airflow will be guided, the airflow velocity and flow rate will be increased, the airflow will be cut into smaller parts, the resistance loss will be reduced, and the smoothness of the airflow will be improved. Then, the rectifying cone 8 will be used to integrate and adjust the oil fume airflow, reduce wind resistance, and make the airflow flow into the air inlet more smoothly, and the steam holes on the surface of the rectifying cone 8 will spray hot steam to block the oil fume airflow outside the rectifying cone 8, so that the oil fume does not adhere to the surface of the rectifying cone 8 and the center column 7. The hot steam and the oil fume airflow are mixed, and the grease in the oil fume will be softened, and it is not easy to adhere to the filter, thereby improving the self-cleaning ability of the device.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the radial filter screen is formed by a filter screen wire that rotates relatively along the circumferential direction between the outer rim 1 and the shaft body 6 and is closely wound and woven, and the filter screen wires of the radial filter screen do not overlap.
[0026] The above scheme is adopted: through the design of the radial filter, since the filter wires of the radial filter do not overlap, they can be wound more tightly and evenly, and the stability will be better; and too fine filter wires are easy to break, and a single filter wire is used for continuous winding and weaving. The manufacturing process is easy to control, and can ensure the weaving angle, density and uniformity between adjacent filter wires, and can also effectively avoid filter wire breakage and extend the service life of the filter disc.
[0027] like Figure 1 As shown, there are multiple air-increasing holes on the surface of the fairing cone 8, and the holes are evenly distributed in an array on the surface of the fairing cone 8. A layer of adhesive film is coated on the outer rim 1 and the filter wire wound thereon.
[0028] The above scheme is adopted: through the design of the rectifying cone 8, the steam generating device can input hot steam into the interior of the gas transmission pipe 9 during operation. Since the steam holes are evenly arrayed on the surface of the rectifying cone 8, the hot steam will be evenly discharged from the steam holes, and the discharged hot steam will mix with the oil smoke to soften the oil smoke, making it difficult to adhere to the filter. Through the design of the outer rim 1, since the outer rim 1 and the filter wire wrapped thereon are coated with a layer of adhesive film, it can be ensured that the filter wire is firmly and reliably bonded to the surface of the outer rim 1, thereby improving its stability and service life during operation.
[0029] like Figure 1 , Figure 2 and Figure 3As shown, the housing bracket 3 is cut and welded from steel plates, a latch is installed on the shaft 6 near the coupling 5, a pressing pin is keyed to the keyway between the shaft 6 and the center column 7 at the joint, and the outer rim 1 is cut from steel plates.
[0030] The above scheme is adopted: through the design of the outer shell bracket 3, the coupling 5 and the shaft body 6, the outer shell bracket 3 cut and welded by the steel plate has high strength and stability, can withstand various forces and vibrations generated during the operation of the oil fume purification device, and ensure the long-term stable operation of the device, and the shaft body 6 is installed with a pin near the coupling 5, so as to facilitate the disassembly and replacement of the filter plate, and through the design of the outer rim 1, the shaft body 6 and the center column 7, the shaft body 6 and the center column 7 are pressed in the keyway by the pin key, so that the connection between the two is tighter and more stable, and it is not easy to loosen or deviate, thereby ensuring the stability of the oil fume purification device during high-speed operation, and the outer rim 1 is designed as a steel plate, so it has good corrosion resistance, can resist the erosion of corrosive substances such as oil fume and water vapor in the kitchen environment, and extend the service life of the outer rim 1.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the fan blades 2 and the center column 7 are made of metal materials, and the fan blades 2 and the center column 7 are fixed by welding. The rectifying cone 8 is made of alloy, and the rectifying cone 8 is connected to the housing bracket 3 by welding.
[0032] The above scheme is adopted: through the design of the fan blades 2 and the center column 7, the metal material has good thermal conductivity, can quickly transfer the heat generated by the fan blades 2 to the surrounding environment, and reduce the operating temperature of the device, and the fan blades 2 and the center column 7 are fixed by welding to form a stable connection structure to ensure the stable operation of the fan blades 2. Through the design of the rectifying cone 8, the rectifying cone 8 is made of an alloy. The alloy material usually has high strength and wear resistance, which can ensure the long-term stable operation of the rectifying cone, and the rectifying cone 8 can be milled by a machine tool, and the rectifying cone 8 is connected to the outer shell bracket 3 by welding, which can ensure the tight connection between the rectifying cone and the outer shell bracket to prevent loosening during operation.
[0033] like Figure 1 As shown, the two outer rims 1 are cut from iron plates and are connected to the fan blades 2 by welding. One or two filter discs are provided on the surface of the shaft body 6, and the filter discs are fixed to the surface of the shaft body 6 at intervals by retaining springs. One end of the rectifier cone 8 is fixedly connected to the outer rim 1, and the other end is fixed to the air pipe 9.
[0034] The above scheme is adopted: through the design of the outer rim 1, the upper outer rim 1 cut from iron plate can reduce the manufacturing cost of the oil fume purification device, and the welded outer rim 1 and the fan blades 2 will form an integral structure, which helps to improve the strength and stability of the entire oil fume purification device. Through the design of the shaft body 6, the rectifying cone 8 and the air pipe 9, one or two filter discs are provided on the surface of the shaft body 6, thereby forming a multi-stage filtration. Each stage of the filter disc can filter and purify the oil fume to a certain extent, thereby improving the overall oil fume purification efficiency, and through the cooperation of the rectifying cone 8 and the air pipe 9, the oil fume airflow is integrated and adjusted to make the airflow flow in more smoothly.
[0035] The working principle and use process of the present invention:
[0036] First, the operator evenly winds the filter wire along the circumferential direction of the outer rim 1 to form a radial filter; then the entire device can be installed in the specified position, and the motor 4 can be driven to make its output end drive the coupling 5 to rotate, and the coupling 5 will drive the shaft 6, the center column 7 and the fan blades 2 to rotate. During the rotation of the fan blades 2, the direction of the oil fume airflow will be guided, so that the airflow is cut into smaller parts, reducing resistance loss and improving the smoothness of the airflow. The rectifying cone 8 is used to integrate and adjust the oil fume airflow to reduce wind resistance and make the airflow flow more smoothly into the air inlet, and the steam generating device is driven to make the hot steam pass through the gas pipe 9 and flow from the inside of the steam hole, blocking the oil fume airflow outside the rectifying cone 8, so that the oil fume does not adhere to the surface of the rectifying cone 8 and the center column 7, thereby improving the self-cleaning ability of the device and finally completing the operation process.
