Description

Technical Field

[0001] This invention relates to the field of equipment for recycling graphite crucible consumables used in graphitization Atchison furnaces, specifically to an integrated device for converting waste crucible bottoms into lids and crushing them. Background Technology

[0002] The Atchison-type graphitization furnace is a heat treatment furnace that promotes the crystallization of graphite in carbonized carbonaceous materials. It is a direct-heating electric furnace. Its basic structure consists of a furnace core composed of carbon billets and granular materials inside a long furnace body made of refractory material. The furnace is surrounded by heat-insulating material. Electricity is passed through conductive electrodes, and the high temperature is generated by the heating of the resistance material. After being energized, the high temperature of 2800-3000℃ is mainly generated by the heating of the resistance material, which indirectly heats the product to complete the graphitization.

[0003] The current practice of processing waste crucibles by manually crushing them and then packaging them into ton bags for sale has the following drawbacks:

[0004] (1) High labor costs: The cost of manually crushing a single waste crucible is 5 yuan, and about 20,000 crucibles are processed annually, resulting in an annual labor cost of 100,000 yuan.

[0005] (2) Low resource utilization rate, no secondary development of the usable part at the bottom of the waste crucible, direct crushing reduces the added value of resources;

[0006] (3) The processing efficiency is low, the manual operation is slow, and it cannot match the enterprise's waste crucible processing speed;

[0007] (4) The working environment is poor, and the dust pollution during the crushing process is serious, posing safety and occupational health hazards;

[0008] (5) The processes are scattered and there is no integrated equipment. Bottom-to-cover conversion, crushing, and bagging need to be completed manually in separate steps, resulting in poor coordination. Summary of the Invention

The single-axis linear module 501 is fixed to the lower surface of the cantilever 2. An electric hoist 502 is fixed to the bottom end of the single-axis linear module 501. A lifting rope 503 is fixedly wound around the outside of the electric hoist 502. One end of the lifting rope 503 is fixed to the electric hoist 502.

[0042] It should be noted that the connecting plate 506 is L-shaped, and the mounting cover 508 and the positioning roller 509 are located directly above the support roller 415 to position the waste crucible and prevent it from shifting during the cutting process. The third motor 505 drives the connecting plate 506 to rotate, which can free up the space above the support roller 415 so that the anti-slip hook 504 can lift the waste crucible to the support roller 415.

[0043] For details, please refer to Figure 5In order to transfer the waste crucible after cutting, the transfer mechanism 7 includes a third rotating rod 701. The upper surface of the guide plate 6 is provided with an installation port 702.

A fourth gear 708 is fixed on the outer side of the fourth rotating rod 707. The outer side of the fourth gear 708 meshes with the inner side of the other end of the second chain 704.

[0044] In this embodiment, there are two third gears 703 and two fourth gears 708, which are symmetrically distributed on the central axes of the third rotating rod 701 and the fourth rotating rod 707, respectively.

Multiple conveyor plates 709 are fixed on the outside of the two second chains 704, and a lifting plate 710 is fixed on the upper surface of the bottommost conveyor plate 709.

[0045] It should be noted that the lifting plate 710 is located inside the mounting port 702, and the width of the lifting plate 710 is adapted to the width of the mounting port 702, so that the waste crucible will not be bumped when it rolls on the guide plate 6, thus preventing the waste crucible from falling off. After the fourth motor 706 completes the transfer of the waste crucible by the lifting plate 710, it will reverse to return the lifting plate 710 to its initial position, waiting for the next transfer. There are two third mounting plates 705, which are symmetrically distributed front and back around the central axis of the crushing table 3. The lower surface of the third mounting plate 705 and the lower surface of the third support are located in the same plane.

[0046] For details, please refer to Figure 6-7To facilitate the recycling of the waste crucibles after cutting, the crushing mechanism 8 includes a fixed jaw plate 801, which is fixed to the upper surface of the crushing table 3. A first crushing spike 802 is fixed to the right side of the fixed jaw plate 801. A fixed plate 803 is fixed to the upper surface of the crushing table 3. A hydraulic cylinder 804 is fixed to the right side of the fixed plate 803.

A second crushing spike is fixed to the left side of the movable jaw plate 805. The crushing table 3 has a discharge port 807 on its upper surface and a connecting groove 808 on the right side of the discharge port 807. A second cylinder 809 is fixed on the right side of the crushing table 3. The output shaft of the second cylinder 809 passes through and extends into the interior of the connecting groove 808 and is fixed with a gate plate 810. A weighing scale 811 is installed below the crushing table 3. A discharge hopper 812 is fixed on the lower surface of the crushing table 3. A hook 813 is fixed on the outside of the discharge hopper 812. A ton bag 814 is installed on the hook 813.

[0047] In this embodiment, the length, width and height of the gate 810 are adapted to the length, width and height of the connecting groove 808, and the length and width of the gate 810 are adapted to the length and width of the discharge port 807.

[0048] It should be noted that there are at least two first crushing spikes 802, which are evenly distributed on the right side of the fixed jaw plate 801, and at least two second crushing spikes 806, which are evenly distributed on the left side of the movable jaw plate 805. The second crushing spikes 806 and the first crushing spikes 802 are staggered to ensure thorough crushing of the waste crucible. There are four hooks 813, which are symmetrically distributed around the central axis of the discharge hopper 812. There are four handles on the outside of the ton bag 814, which correspond one-to-one with the positions of the four hooks 813. The four handles are suspended from the four hooks 813 respectively, so that the ton bag 814 can be kept open to allow the waste crucible fragments to enter the ton bag 814 better.

[0049] The electrical components are controlled by an electrical control system, which is based on a PLC, equipped with a touch screen, emergency stop button, and multiple types of sensors. It supports automatic / manual modes and automatically cycles according to the logic of "lifting and positioning → cutting → conveying → crushing → bagging". It has fault alarm and status monitoring.

[0050] The working principle of the above embodiments is as follows:

[0051] (1) First, the waste crucible is hoisted between the two support rollers 415 using the electric hoist 502, lifting rope 503, and anti-slip hook 504. Then, the first cylinder 507 is opened, which drives the mounting cover 508 and positioning roller 509 to move downwards, so that the positioning roller 509 contacts the waste crucible to achieve positioning of the waste crucible. At this time, the dual-axis linear module 401 is opened to adjust the cutting position of the waste crucible. Then, the first motor 405 is opened, which drives the saw blade 406 to rotate, so that the saw blade 406 cuts into the waste crucible, and the dust cover 404 covers the cutting position to prevent dust pollution. At this time, the second motor 408 is opened. The first rotating rod 409 and the first gear 410 rotate, and the first gear 410 drives the first chain 411 to drive the second gear 414 and the second rotating rod 413 to rotate in the same direction as the first rotating rod 409. This causes the two support rollers 415 to rotate. With the rotation of the two support rollers 415, the waste crucible rotates, allowing the saw blade 406 to perform circumferential cutting on the waste crucible so that the bottom of the waste crucible can be cut off and transformed into a new crucible lid. During the cutting process, the vacuum cleaner 416 absorbs the generated dust and passes it into the bag filter 419 through the dust outlet pipe 418, thereby reducing the pollution caused by dust.

[0052] (2) After the cutting work is completed, the first cylinder 507 drives the mounting cover 508 to move upward, and at the same time the third motor 505 drives the connecting plate 506 to rotate, making room for the subsequent loading of waste crucibles. Then the workers pry up the remaining waste crucibles and push them into the guide plate 6, so that the waste crucibles are between the conveyor plate 709 and the lifting plate 710. At this time, the fourth motor 706 is turned on, and the fourth motor 706 drives the fourth rotating rod 707 and the fourth gear 708 to rotate. The fourth gear 708 drives the second chain 704 to drive, and the second chain 704 drives the third gear 703 and the third rotating rod 701 to rotate, so that the second chain 704 can drive smoothly, and the conveyor plate 709 and the lifting plate 710 can transfer the waste crucibles, so that the waste crucibles reach the crushing table 3.

[0053] (3) After the waste crucible reaches the crushing table 3, the hydraulic cylinder 804 is opened. The output shaft of the hydraulic cylinder 804 drives the moving jaw plate 805 and the second crushing spike 806 to move. Together with the fixed jaw plate 801 and the first crushing spike 802, the waste crucible is crushed. With the cooperation of the discharge hopper 812, the waste crucible fragments enter the ton bag 814. The weighing scale 811 weighs the ton bag 814 in real time. When the weight reaches the threshold, the second cylinder 809 is opened, and the gate plate 810 is pushed into the discharge port 807, so that the feeding work stops and waits for the ton bag 814 to be replaced before it is opened again.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
