[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0024] Combination Figure 1-Figure 6 As shown, the present invention provides a metallurgical fume treatment device, comprising a box body 1 and a mounting plate 2 installed in the box body 1, and an ash discharge hopper is provided at the lower end of the box body 1. A plurality of dust removal units 3 are installed on the mounting plate 2, and an air inlet pipe 4 and an air outlet pipe 5 are connected to the box body 1, and the air inlet pipe 4 and the air outlet pipe 5 are respectively located below and above the mounting plate 2.

[0025] The metallurgical flue gas treatment device of the present invention has the following process for treating flue gas: the flue gas enters the box through the air inlet pipe 4, which is located outside the dust removal unit 3. The smoke is filtered outside the dust removal unit 3 by the filtering action of the dust removal unit 3, and the clean gas enters the dust removal unit 3 and is discharged through the air outlet pipe 5.

[0026] The metallurgical fume treatment device of the present invention needs to clean the dust removal unit 3 after working for a period of time to ensure its filtering effect. In the present invention, a cleaning assembly 6 is provided on the lower side of the mounting plate 2, and the cleaning assembly 6 is connected to a driving device 7. According to one embodiment of the present invention, the cleaning assembly 6 includes an upper movable plate 61 and a lower movable plate 62, the upper movable plate 61 and the lower movable plate 62 are in contact with each other, and the upper movable plate 61 and the lower movable plate 62 are connected by a spring 63. Specifically, mounting grooves are correspondingly provided on the lower side of the upper movable plate 61 and the upper side of the lower movable plate 62, and the springs are installed in the mounting grooves.

[0027] In this embodiment, sliders 611 are provided at both ends of the upper movable plate 61, and a slide groove 11 is provided on the box body 1 to match the sliders 611. The driving device 7 includes a motor 71 installed on the top of the box body 1 and a threaded rod 72 connected to the motor 71, and the threaded rod 72 passes through the upper movable plate 61 and is threadedly matched with the lower movable plate 62. The upper movable plate 61 and the lower movable plate 62 are also provided with guide holes 621 correspondingly, and the guide rod 12 is also provided through the guide holes 621.

[0028] The cleaning process of the metallurgical fume treatment device of the present invention is as follows:

[0029] When it is necessary to clean the outer wall of the dust removal unit 3, the motor 71 works, driving the threaded rod 72 to rotate, thereby driving the lower moving plate 62 to move downward, and the lower moving plate 62 and the upper moving plate 61 are connected by the spring 63, thereby driving the upper moving plate 61 to move downward, and the lower moving plate 62 moves downward to scrape the outer wall of the dust removal unit 3, and clean the smoke and dust. Most of the smoke and dust will fall into the ash discharge hopper, and a small part will adhere to the lower surface of the lower moving plate 62. When the motor 71 works to make the upper moving plate 61 move to the limit position of the chute 11, the upper moving plate 61 cannot continue to move downward, and at this time, the motor 71 can continue to work, so that the lower moving plate 62 continues to move downward, so that the spring 63 can be stretched. After the cleaning work is completed, the motor 71 is reversed, and the lower moving plate 62 is reset upward under the action of the motor 71 and the spring 63. During the reset process, the lower moving plate 62 is vibrated and impacted, which is conducive to the falling of the smoke and dust on the lower moving plate 62 to improve the cleaning effect.

[0030] According to one embodiment of the present invention, an air supply device 8 is further included, and the air supply device 8 includes an air supply box 81, an air supply pipe 82 connected to the air supply box 81, and a nozzle 83 installed on the air supply pipe 82. The air supply pipe 82 extends into the box body 1, and the nozzle 83 is located above the dust removal unit 3.

[0031] The metallurgical fume treatment device of the present invention can perform backblowing from above the dust removal unit 3 through the provision of the air supply device 8, thereby achieving cleaning of the dust removal unit 3, which is beneficial to further improve the cleaning effect.

[0032] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
