Description

Technical Field

[0001] The invention relates to the technical field of steel processing, and in particular to a waste slag recovery device capable of multiple screening. Background Art

[0002] A lot of waste slag is produced in the process of steel processing. The waste slag contains certain valuable metal components and can be reused after further processing. Therefore, the waste slag has recycling value.

[0003] In the process of waste slag recycling, the waste slag needs to be crushed first, and then screened and separated to separate metal waste slag of different particle sizes, so as to improve the efficiency of subsequent recycling operations. In the prior art, multi-stage vibrating screens or drum screens are usually used to screen and separate the waste slag. The volumes of the waste slag are different. During the operation of the multi-stage vibrating screen, since the waste slag needs to pass through the multi-stage vibrating filter plates, some waste slag with a volume close to the sieve hole diameter will block the sieve hole, which reduces the efficiency of the multi-stage vibrating screen and causes the multi-stage vibrating screen to be unable to quickly separate all the waste slag according to different volume ranges. Separation, the drum screen needs to drive the waste residue to rotate and gradually tilt downward. In the process of the waste residue rolling and sliding downward, the limited number of rotations of the rolling screen cannot separate the waste residue according to the volume range well, and there is also the situation that the waste residue with a volume close to the aperture of the sieve hole blocks the sieve hole, which is not conducive to subsequent recycling and processing, and the vibration amplitude of the above two screening machines cannot be adjusted. When separating small-volume waste residue, weaker vibration cannot be used to form a good stratification of the waste residue, and when separating large-volume waste residue, strong vibration cannot be used to make the large-volume waste residue roll, which is not conducive to screening efficiency.

[0018] As described above, the characteristics and advantages of the waste slag recovery device capable of multiple screening in the present invention are:

[0019] Through the arrangement of the sliding groove and the sliding plate, a group of sliding plates slide in the sliding groove, so that the baffle rod inside the sliding plate fixedly connected to the slider one moves away from directly above the screen plate. During this process, the toggle block rotates to the bottom end in the toggle groove. At this time, only the baffle rod parallel to the screw rod one blocks the screen plate, so that larger waste residues can pass through the sieve holes formed by the baffle rod and the sieve plate, thereby achieving the effect of screening larger waste residues. In addition, the baffle rod is translated above the sieve plate to adjust the sieve hole size, which can effectively prevent larger waste residues from blocking the sieve holes.

[0020] By setting the first and second pulleys, when the rotating seat rotates to switch the recovery box, the vertical rod on the top of the rotating seat will synchronously drive the two pulleys to rotate, so that the threaded cylinder moves the threaded rod downward through the threaded cooperation with the threaded rod, thereby making the circular plate move downward in the limiting cylinder. At this time, the distance between the circular plate and the top of the limiting cylinder becomes larger, increasing the distance the limiting cylinder moves downward, thereby increasing the activity amplitude of the mounting frame during vibration, so that when screening smaller waste residues, the vibration amplitude of the mounting frame is smaller, so as to ensure that small-volume waste residues can be smoothly layered and screened on the screen surface, and when switching to the state of screening larger-volume waste residues, the vibration amplitude of the mounting frame is increased, so that the remaining larger-volume waste residues can produce sufficient rolling to ensure the screening effect;

[0021] Through the cooperation of the limiting cylinder and the circular plate, the two limiting cylinders limit the vertical vibration of the mounting frame from both sides of the mounting frame. Compared with the prior art in which a single vibrator is provided for the vibrating screen, the vibration is concentrated on one side of the vibrating screen during screening, resulting in different vibration amplitudes on the entire vibrating screen. The limiting mechanism limits the vibration of the mounting frame, the screen plate and the screen plate, making the vibration of the screen plate more uniform and the vibration amplitude consistent, thereby ensuring the overall screening effect of the screen plate on the waste slag.

[0022] Through the setting of the rotating seat, the reduction motor module drives the rotating seat to rotate 90 degrees, rotates the recycling box containing smaller waste slag away from the bottom of the mounting frame, and rotates the empty recycling box to the bottom of the mounting frame. At this time, the recycling box containing smaller waste slag can be taken out from the placement seat, so that after the slag is discharged from the furnace, the slag can be immediately screened and separated, so as to facilitate the classification and treatment of slag of different volumes after separation, avoiding the problem of slag discharged from the slag discharge port directly accumulating on the ground, resulting in a large amount of space occupied, and also reducing the pollution of nearby soil and water bodies when the slag is placed on the ground, which helps to improve the environmental protection benefits of waste slag treatment;

[0023] Through the setting of the rotating seat and the push switch, the vibration amplitude of the mounting frame and the size of the sieve hole can be switched synchronously during the process of switching the recycling bins. Therefore, when the four recycling bins are switched and the waste residue inside the recycling bins is processed, the multiple screening structures above the recycling bins are synchronously switched to the state of screening waste residues of different volumes, thereby achieving the effect of quickly separating waste residues of different volumes without the need for manual switching, which is beneficial to improving the efficiency of waste residue recycling.

[0042] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0043] The initial state is:

[0044] The motor 309 is not started, the slider 1 310 is located in the middle of the screw 1 308, the toggle block 313 is located at the top of the toggle slot 312, the slider 2 317 is located in the middle of the screw 2 316, the two sets of sliding plates 306 are both located in the middle of the sliding slot 305, the two sets of blocking rods 307 do not block the top of the sieve plate 304 and are in a cross state, the vibrator 403 is not started, the rotating seat 408 does not rotate, one of the rotating arms 420, the placement seat 421 and the recovery box 422 are located directly below the fixed frame 301, all the push switches 419 are not blocked by the threaded cylinder 415, and the round plate 418 is located at the bottom of the limit cylinder 417.

[0045] The working status is:

[0046] Vibration screening of waste residue:

[0047] The feed rack 318 is aligned with the slag discharge port of the furnace and placed. When the slag falls into the feed rack 318 from the slag discharge port, the vibrator 403 is started and vibrates, so that the movable plate 402 quickly swings up and down with the connection point of the connecting seat 401 as the axis. When the movable plate 402 quickly swings with the connection point with the connecting seat 401 as the base point, the limit rod 405 cooperates with the through hole 404 and the baffle 406, so that the spring 407 is continuously squeezed and stretched by the connecting seat 401 and the baffle 406, so that the vibrator 40 During the vibration, the connecting seat 401 is driven to vibrate, and then the mounting frame 302 is driven to vibrate. After the vibration is transmitted to the mounting frame 302, the mounting frame 302 generates a vibration effect with a larger range of motion under the action of the four vibration seats 319, so that the mounting frame 302 drives the waste residue in the feeding frame 318 to vibrate. At this time, the waste residue with a smaller volume will pass through the sieve holes formed by the blocking rod 307 and the sieve plate 304 in a cross state, and then fall into the recovery box 422 located just below the mounting frame 302 for collection.

[0048] Toggle Recycle Bin 422:

[0049] When smaller waste slag is separated from the waste slag pile to the inside of the recycling box 422 under the action of vibration, the reduction motor module at the bottom of the rotating seat 408 is started, so that the reduction motor module drives the rotating seat 408 to rotate ninety degrees, and the recycling box 422 containing smaller waste slag is rotated away from the bottom of the mounting frame 302, and the empty recycling box 422 is rotated to the bottom of the mounting frame 302. At this time, the recycling box 422 containing smaller waste slag can be taken out from the placement seat 421, so that after the slag is discharged from the furnace, the slag can be immediately screened and separated for multiple times, so as to facilitate the classification and treatment of slag of different volumes after separation, avoiding the slag discharged from the slag discharge port directly accumulating on the ground, resulting in the problem of occupying a large amount of space, and also reducing the pollution of nearby soil and water bodies when the slag is placed on the ground, which helps to improve the environmental protection benefits of waste slag treatment.

[0050] Switch the vibration amplitude of the mounting frame 302:

[0051] When the rotating seat 408 rotates to switch the recycling box 422, the vertical rod 409 on the top of the rotating seat 408 will synchronously drive the two pulleys 1 411 to rotate, so that the two pulleys 1 411 drive the two pulleys 2 412 to rotate through the belt 1, and at the same time, the two pulleys 2 412 drive the pulley 3 413 to rotate, so that the two pulleys 3 413 drive the two pulleys 4 414 to rotate through the belt 2, and then drive the two threaded cylinders 415 to rotate, so that the threaded cylinder 415 moves the threaded rod 416 downward by cooperating with the thread of the threaded rod 416, so that the circular plate 418 moves downward in the limiting cylinder 417. When the mounting frame 302 vibrates again, the mounting frame 302 is fixedly connected to the limiting cylinder 417, and the circular plate 418 moves upward, which increases the distance that the limiting cylinder 417 moves downward, thereby increasing the vibration amplitude of the mounting frame 302. When screening smaller waste residues, the vibration amplitude of the mounting frame 302 is smaller to ensure that small-volume waste residues can be smoothly layered and screened on the screen surface. When switching to the state of screening larger waste residues, the vibration amplitude of the mounting frame 302 is increased, so that the remaining larger-volume waste residues can produce sufficient rolling to ensure the screening effect.

[0052] Make the vibration more uniform:

[0053] When the vibrator 403 is started, the movable plate 402 cooperates with the spring 407 to drive the mounting frame 302 and its internal structure to vibrate, so that the limiting cylinder 417 fixedly connected to the side of the mounting frame 302 and the sliding cooperation of the circular plate 418 make the two limiting cylinders 417 limit the vertical vibration of the mounting frame 302 from both sides of the mounting frame 302. Compared with the prior art in which a single vibrator 403 is set for the vibrating screen, the vibration is concentrated on one side of the vibrating screen during screening, resulting in different vibration amplitudes on the entire vibrating screen. The mounting frame 302, the sieve plate 304 and the sieve plate 304 are limited to vibrate up and down, so that the sieve plate 304 vibrates more evenly and the vibration amplitude is consistent, thereby ensuring the overall screening effect of the sieve plate 304 on the waste residue.

[0054] Switch the aperture of the sieve plate 304:

[0055] When the threaded cylinder 415 drives the threaded rod 416 to descend, thereby increasing the movable range of the mounting bracket 302, the threaded rod 416 continues to descend so that the push switch 419 is blocked. When the push switch 419 is squeezed, the motor 309 is started, driving the screw rod 308 to rotate, so that the screw rod 308 drives the slider 310 to slide to the side away from the motor 309, thereby driving a group of sliding plates 306 fixedly connected to the slider 310 to slide in the sliding groove 305, and then the blocking rod 307 inside the sliding plate 306 fixedly connected to the slider 310 is moved away from the top of the sieve hole of the sieve plate 304. In this process, the toggle block 313 rotates to the bottom end in the toggle groove 312, but the cylindrical sleeve 311 is not toggled to rotate. At this time, only the blocking rod 307 parallel to the screw rod 308 blocks the top of the sieve hole of the sieve plate 304, so that larger waste slag can pass through the sieve hole on the sieve plate 304, thereby achieving the effect of screening larger waste slag.

[0056] Further switch the aperture of the sieve plate 304:

[0057] When the screening of the larger waste residue is completed and the empty recycling box 422 is rotated to the bottom of the mounting frame 302 by the rotating seat 408, the threaded rod 416 moves further downward in the threaded cylinder 415, so that the push switch 419 located below is also squeezed by the threaded rod 416, thereby starting the motor 309 again, so that the motor 309 starts the screw rod 1 308 to rotate again, so that the toggle block 313 on the screw rod 1 308 contacts the bottom end of the toggle slot 312, and further drives the cylindrical sleeve 311 to rotate through the toggle slot 312, thereby driving the screw rod 2 316 to rotate through the active bevel gear 314 and the driven bevel gear 315, and the screw rod 2 316 316 Drive slider 2 317 to slide in the direction away from the driven bevel gear 315, so that slider 2 317 drives a group of sliding plates 306 fixedly connected to it to slide in the sliding groove 305 in the direction away from the driven bevel gear 315, thereby driving the blocking rod 307 parallel to screw rod 1 308 to move so that it no longer blocks the sieve holes on the sieve plate 304. At this time, both groups of blocking rods 307 are not located above the sieve holes on the sieve plate 304, so that larger waste slag can pass through the sieve plate 304 and fall into the recycling box 422 for collection, thereby achieving the effect of multiple screening, so as to improve the resource recovery rate of the waste slag, and facilitate the subsequent comprehensive utilization, thereby achieving the effect of increasing the recycling value of the waste slag.

[0058] The above descriptions are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
