[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 4 The smoke filter device of a secondary aluminum smelting furnace shown in the figure includes a dust collector body 1, a vibration mechanism is provided inside the dust collector body 1, and the vibration mechanism includes a drive motor 7 fixedly mounted on the top of the dust collector body 1, the output end of the drive motor 7 is fixedly connected to the rotating shaft 8, the bottom end of the rotating shaft 8 is fixedly mounted with a connecting plate 12, the interior of the connecting plate 12 is fixedly connected to the arc-edged rotating disk 13, the inner wall of the dust collector body 1 is provided with a mounting hole 18, the interior of the mounting hole 18 is installed with an elastic member 17, and the end of the elastic member 17 away from the dust collector body 1 is fixedly mounted with a pressure plate 1 5. The end of the pressure plate 15 opposite to the elastic member 17 is fixedly connected to the vibration rod 14, and the outer surface of the vibration rod 14 is fixedly connected to a plurality of toggle rods 16. When too much dust accumulates on the surface of the filter bag 11, the vibration mechanism can be driven by the driving motor 7 to operate, so that the toggle rods 16 continuously act on the surface of the filter bag 11 to knock down the dust on the surface of the filter bag 11. In this way, the filter bag 11 can be cleaned during the operation of the bag dust collector without interrupting the operation of the dust collector, ensuring the working efficiency and the service life of the filter bag 11.

[0021] An ash hopper 2 is fixedly connected to the bottom end of the dust collector body 1, and an ash discharge mechanism 3 is provided inside the ash hopper 2. The ash discharge mechanism 3 can collect dust in the flue gas to ensure that the discharged flue gas is free of particulate impurities, thereby causing air pollution. An air inlet 4 is provided on one side of the ash hopper 2, and an air outlet 5 is provided on one side of the top of the dust collector body 1. The air inlet 4 is used for the entry of unfiltered flue gas, and the air outlet 5 is used to discharge the filtered flue gas.

[0022] A partition 9 is fixedly connected to the inside of the dust collector body 1, and a plurality of vents 10 are provided inside the partition 9. A plurality of filter bags 11 are fixedly installed at the bottom end of the partition 9. The filter bags 11 can capture solid particles in the flue gas, such as dust, powder, etc., but can allow gas to pass through, thereby purifying the gas and ensuring that the discharged gas is free of solid particles to prevent air pollution.

[0023] The partition 9 and the interior of the dust collector body 1 form a clean air chamber. The number of vents 10 is the same as the number of filter bags 11. The filter bags 11 are installed directly below the vents 10. The purified gas will enter the clean air chamber through the vents 10 and be discharged from the air outlet 5.

[0024] A pulse mechanism 6 is provided on the top of the dust collector body 1 on the side opposite to the air outlet 5. The output end of the pulse mechanism 6 is located in the clean air chamber. The pulse mechanism 6 can use high-speed jet airflow to pass through the top of the filter bag 11 and blow toward the inside of the filter bag 11 to form air waves, causing the filter bag 11 to expand and vibrate rapidly from top to bottom, thereby producing a strong dust removal effect. When no work is needed, the filter bag 11 can be thoroughly cleaned by the pulse mechanism 6.

[0025] The end of the vibration rod 14 away from the pressure plate 15 is arranged inside the connecting disk 12 and cooperates with the arc-edge turntable 13. The toggle rod 16 acts on the filter bag 11 through the control of the drive motor 7. The drive motor 7 can drive the vibration mechanism to operate, so that the toggle rod 16 continuously acts on the filter bag 11, which can knock off the dust on the surface of the filter bag 11.

[0026] Working principle: First, the flue gas pipe generated in the production of recycled aluminum is connected to this device, and then the flue gas will enter the interior of the device. The flue gas will first come into contact with the filter bag 11, and the dust and dust contained in the flue gas will adhere to the surface of the filter bag 11. The filtered flue gas will pass through the filter bag 11 and enter the clean air chamber through the air vent 10, and then be discharged from the air outlet 5. In the process of filtering the flue gas generated in the production of recycled aluminum, the dust accumulated on the filter bag 11 will affect the air permeability of the filter bag 11 itself, thereby reducing the working efficiency of filtering the flue gas. During work, the driving motor 7 can be used to drive the connecting disk 12 to rotate. Due to the cooperation of the arc-edge turntable 13 and the vibration rod 14, and under the action of the elastic member 17, the toggle rod 16 continuously toggles the filter bag 11, so that the dust on the surface of the filter bag 11 falls off, thereby completing the cleaning work of the filter bag 11 without affecting the working efficiency of filtering the flue gas, and ensuring that the filter bag 11 has good air permeability.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention.
