In the invention, the collecting device comprises a sewage collecting box 8 and an installation platform 9, the sewage collecting box 8 is clamped on the installation platform 9 and is convenient to install or disassemble, the sewage collecting box 8 is arc-shaped, a communication opening 11 is formed in the side wall of the bent pipe, and the installation platform 9 is hermetically arranged at the communication opening 11.
In the invention, two sealing plates 10 are slidably arranged at the opposite positions of the mounting table 9 and the communication port 11, electromagnets 101 are respectively arranged in the two sealing plates 10, the two electromagnets 101 are electrically connected with a power supply 7 through a time delay capacitor, and the time delay capacitor has the functions of: in a period of time after the electric signal of touching sensor 52 department disappears, for electro-magnet 101 provides the electric energy, two electro-magnets 101 homopolarly are relative, repel each other after the circular telegram, drive two sealing plates 10 alternate segregation, make the plug automatically fall into in the dirty box 8 that gathers, are located to be equipped with miniature spring between electro-magnet 101 and the mount table 9 of below, make electro-magnet 101 of below can automatic re-setting when the outage.
According to the invention, a circular groove 15 is formed in the vertical pipe, the sliding rod 3 penetrates through the circular groove 15, the flexible sheet 12 is arranged on the side wall of the sliding rod 3, the pressure sensor 13 corresponding to the position of the flexible sheet 12 is arranged in the circular groove 15, and the flexible sheet 12 is in contact with the pressure sensor 13 in an initial state.
In the invention, a plurality of heating sheets 21 are symmetrically arranged in the wing plate 2, and the plurality of heating sheets 21, the power supply 7 and the pressure sensor 13 form a closed loop together.
The invention can be illustrated by the following operating modes: waste gas enters from a vertical pipe of the exhaust pipeline 1 and is discharged from a bent pipe, and the principle of fluid mechanics shows that the gas flow rate is larger on one convex side of the wing plate 2 compared with the horizontal side, and the air pressure is smaller, so that the wing plate 2 can be subjected to right-hand pulling force, the wing plate 2 drives the balance plate 5 to move right through the sliding rod 3, the higher the waste gas discharge speed is, the larger the acting force on the wing plate 2 is, and the larger the compression amount of the compression spring 6 is;
after the flow velocity of the exhaust gas in the exhaust pipeline 1 reaches a certain value, the wing plate 2 can realize the maximum displacement, at the moment, the trigger point 51 is abutted against the touch sensor 52, the touch sensor 52 can generate an electric signal, after the exhaust gas in the exhaust pipeline 1 is discharged, the balance plate 5 can reset under the action of the compression spring 6, so that the trigger point 51 is separated from the touch sensor 52, and because the electromagnets 101 in the two sealing plates 10 are electrically connected with the power supply 7 through the time delay capacitor, the power supply 7 can provide electric energy for the electromagnets 101 in a period of time after the electric signal at the position of the touch sensor 52 disappears;
the electromagnets 101 in the two sealing plates 10 are homopolar and opposite and repel each other after being electrified, so that the two sealing plates 10 are separated from each other, dust and oil dirt accumulated on the sealing plates 10 are scraped off when the sealing plates 10 move and enter the dirt collecting box 8, the oil dirt is prevented from being accumulated at the bent pipe, and the waste gas can still be discharged at a high speed after the exhaust pipeline is used for a long time;
it is worth mentioning that the lower sealing plate 10 is slightly lower than the height of the communication opening 11 after being fully opened, as shown in fig. 1, to ensure that the scraped oil can fall into the dirt collecting box 8 instead of the elbow;
when the exhaust speed of the exhaust pipeline 1 is low, the exhaust gas discharge amount is small, the phenomenon of obvious backflow cannot be caused by sudden exhaust interruption, in the actual exhaust gas treatment process, the conditions of high-speed exhaust and sudden interruption can often occur, and the pressure intensity in the exhaust pipeline 1 is far lower than the external pressure intensity, so that the phenomenon that the discharged exhaust gas obviously flows back into the exhaust pipeline 1 can occur, therefore, the time-delay capacitor can ensure that the sealing plate 10 is in an open state when the exhaust gas flows back, the direction of the exhaust gas passing through the arc-shaped dirt collecting box 8 is changed, the kinetic energy of the gas can be effectively reduced, the gas flow speed is reduced, the sedimentation of dust and grease is accelerated, and the gas can be prevented from flowing upwards to a higher position along a vertical pipe;
when the electromagnet 101 is powered off, the sealing plate 10 positioned above automatically slides down, the sealing plate 10 positioned below automatically moves upwards under the action of the micro spring to seal the communication port 11, so that sundries in the dirt collecting box 8 are prevented from being carried out by slow airflow and then adhered to a bent pipe again, and the dirt collecting box 8 is clamped on the mounting table and is convenient to take down, clean and fix;
in the initial state, the flexible sheet 12 is in contact with the pressure sensor 13, and the pressure applied by the flexible sheet 12 to the pressure sensor 13 is set to F1When more oil stains are adhered to the wing plate 2, the pressure applied by the flexible sheet 12 to the pressure sensor 13 is set to F2When the pressure at the pressure sensor 13 is in the range of F1～F2In the meantime, the power supply 7 supplies power to the heating sheet 21, so that the temperature of the surface of the wing plate 2 is increased, condensed grease is melted and dropped, and the convex side of the wing plate 2 is ensured to have larger curvature;
the exhaust gas is mostly high temperature gas, so when the exhaust gas is discharged, the pressure applied to the pressure sensor 13 is much greater than F2And the power supply 7 no longer supplies power to the heating sheet 21, so that the electric energy can be effectively saved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
