This patented device adds a dust interception component to the pipe used to discharge fumes, which can vibrate the intercepted dust into a special dust collection box. This not only facilitates centralized collection and treatment in the later stage, but also avoids dust from adhering for a long time and affecting the ventilation effect of the grating plate.

[0004] However, this patented device can become clogged with dust during prolonged operation, making it unable to simultaneously remove the clogged dust and filter the dust, thus affecting the device's dust filtration and collection efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust collection and treatment device for the smelting process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust collection and treatment device for smelting process includes a box body, and a filter mechanism is provided inside the box body. The filter mechanism includes a rotating ring disposed inside the box body. At least eight rotating cylinders are evenly rotatably connected between the inner and outer walls of the circumferential side of the rotating ring. The inner and outer walls of the circumferential side of the rotating cylinders are evenly provided with openings. Filter screens are fixedly connected between the inner walls of the two openings. Both sides of the box body can be opened and closed.

[0008] Preferably, a baffle is fixedly connected between the two inner walls of the box body, and at least two openings aligned with the rotating ring are provided between the two sides of the baffle, with the rotating ring located inside the two openings. The inside of the baffle is evenly provided with telescopic grooves communicating with the openings, and telescopic blocks are slidably connected between the inner walls of the two sides of the telescopic groove.

[0009] Preferably, a limiting post is fixedly connected to one inner wall of the telescopic groove, the circumferential side of the limiting post is slidably connected to the inside of the telescopic block, one end of the telescopic block extends into the inside of the opening, and a spring surrounding the limiting post is fixedly connected between the other end of the telescopic block and one inner wall of the telescopic groove.

[0010] Preferably, a connecting ring is fixedly connected to the bottom of the rotating ring, the bottom of the connecting ring is rotatably connected to the bottom inner wall of the box, an annular groove is provided at the bottom of the box, a movable ring is rotatably connected to the bottom inner wall of the annular groove, and the top of the movable ring is fixedly connected to the bottom of the connecting ring.

[0011] Preferably, a motor is fixedly connected to the bottom inner wall of the annular groove, a gear is fixedly connected to the output shaft of the motor, the circumferential side of the gear is meshed with the circumferential side of the movable ring, an annular box is fixedly connected to the top inner wall of the housing, and an annular plate is rotatably connected between the bottom inner wall and the outer wall of the annular box.

[0012] Preferably, a connecting pipe is fixedly connected to the top inner wall of the rotating cylinder, and the other end of the connecting pipe passes through the ring plate and extends into the ring box. A toothed ring is fixedly connected to the inner wall of the circumferential side of the ring box, and the circumferential side of the toothed ring is engaged with the circumferential side of the connecting pipe. A fixing pipe is uniformly fixedly connected to the top inner wall of the ring box, and the other end of the fixing pipe extends to the top outer wall of the box. An air inlet pipe is fixedly connected between the inner wall and the outer wall of the side of the box.

[0013] Preferably, an arc-shaped plate is fixedly connected to the top inner wall of the box and surrounds the rotating ring. A cleaning brush is evenly fixedly connected to the circumferential side of the arc-shaped plate. The other end of the cleaning brush abuts against the filter screen. An extension groove is provided between the inner and outer walls of the bottom side of the box. A collection box is detachably connected between the top and bottom of the extension groove. The other end of the collection box extends to below the cleaning brush.

[0014] Compared with the prior art, this utility model provides a dust collection and treatment device for the smelting process, which has the following beneficial effects:

[0015] The rotating drum forces dust-laden airflow into the housing through the inlet pipe. The dust is filtered by the filter, and the airflow then exits the device along the rotating drum, connecting pipe, and fixed pipe. Periodically, the motor drives a gear, which in turn drives a movable ring, which in turn drives a connecting ring, which in turn drives a rotating ring. This rotating ring, in turn, drives the rotating drum and filter, causing unused rotating drums and filters on one side of the baffle to rotate to the other side, replacing those that have been used for a long time. This helps prevent the filter from becoming clogged with dust during prolonged operation, thus preventing the device from malfunctioning. Removing dust from the filter screen affects the dust collection efficiency of the device. As the rotating cylinder rotates with the rotating ring, it drives the connecting pipe to rotate. The connecting pipe rotates as it moves along the toothed ring, causing the rotating cylinder to rotate, which in turn drives the filter screen to rotate. This allows the filter screen to be cleaned by the cleaning brush while rotating, which is beneficial for the device to clean the filter screen regularly and maintain its normal working effect. The dust cleaned by the cleaning brush falls into the collection box for collection. The spring pushes the telescopic block to extend, so that the telescopic block abuts against the rotating ring, preventing a large amount of airflow from entering the other side of the baffle.

[0024] A limiting post 5 is fixedly connected to one inner wall of the telescopic groove 7. The circumferential side of the limiting post 5 is slidably connected to the inside of the telescopic block 8. One end of the telescopic block 8 extends into the inside of the opening. A spring 6 surrounding the limiting post 5 is fixedly connected between the other end of the telescopic block 8 and one inner wall of the telescopic groove 7.

[0025] A connecting ring 18 is fixedly connected to the bottom of the rotating ring 11. The bottom of the connecting ring 18 is rotatably connected to the bottom inner wall of the box 1. An annular groove 17 is provided at the bottom of the box 1. A movable ring 16 is rotatably connected to the bottom inner wall of the annular groove 17. The top of the movable ring 16 is fixedly connected to the bottom of the connecting ring 18.

[0026] A motor 15 is fixedly connected to the bottom inner wall of the annular groove 17. A gear 14 is fixedly connected to the output shaft of the motor 15. The circumferential side of the gear 14 is meshed with the circumferential side of the movable ring 16. An annular box 23 is fixedly connected to the top inner wall of the housing 1. An annular plate 22 is rotatably connected between the bottom inner wall and the outer wall of the annular box 23.

[0027] A connecting pipe 19 is fixedly connected to the top inner wall of the rotating cylinder 9. The other end of the connecting pipe 19 passes through the ring plate 22 and extends into the ring box 23. A toothed ring 21 is fixedly connected to the inner wall of the circumferential side of the ring box 23. The circumferential side of the toothed ring 21 is engaged with the circumferential side of the connecting pipe 19.

This causes unused rotating cylinder 9 and filter screen 10 on one side of baffle 4 to rotate to the other side, replacing those that have been used for a long time. This helps prevent filter screen 10 from becoming clogged with dust during prolonged operation, thus preventing the device from malfunctioning. The method of removing dust from the filter screen 10 while simultaneously filtering dust affects the dust filtration and collection effect of the device. When the rotating cylinder 9 rotates with the rotating ring 11, the rotating cylinder 9 drives the connecting pipe 19 to rotate. When the connecting pipe 19 moves along the toothed ring 21, it rotates, causing the connecting pipe 19 to drive the rotating cylinder 9 to rotate. The rotating cylinder 9 drives the filter screen 10 to rotate, so that the filter screen 10 is cleaned by the cleaning brush 3 while rotating. This is beneficial for the device to clean the filter screen 10 regularly and maintain the normal working effect of the device. The dust cleaned by the cleaning brush 3 falls into the collection box 13 for collection. The spring 6 pushes the telescopic block 8 to extend, so that the telescopic block 8 abuts against the rotating ring 11 to prevent a large amount of airflow from entering the other side of the baffle 4.
