Description

Technical Field

[0001] The present invention relates to the technical field of carbon block unloading, and in particular to an automatic carbon block sorting and unloading machine. Background Art

[0002] At present, on-site carbon block transportation is carried out through containers (export vehicles are transported by trailers) and transported to the carbon block warehouse. The carbon blocks are unloaded by forklifts through mobile unloading platforms. The working environment is complex and there are great safety hazards. In addition, the surface of the carbon blocks is damaged during transportation. Studies have shown that damage to the anode surface will increase the slag shedding during the use of the anode in the electrolytic cell, thereby increasing the gross consumption of the electrolytic anode. Specifically, as shown in the Chinese utility model with patent number 202023020068.6, it lifts the container by a material shifting mechanism and then tilts the container for unloading. However, the structure will have problems with uneven unloading and carbon block breakage. In addition, the Chinese invention patent with patent number 201911049695.1 announces a retractable integrated system for port coke unloading and stacking (reference Figure 4 ), the unloading is achieved by tilting the unloading platform. The existing problems are the same as those of the material-discharging mechanism, that is, unsafe unloading will cause damage to the carbon blocks. In order to increase the safety of unloading carbon blocks, the existing technology will also choose to install air bags or rubber cushions to limit the carbon blocks. However, the cushioning air bags are consumable parts and need to be replaced regularly during use, and the maintenance cost is relatively high. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-8As shown, an automatic charcoal block sorting and unloading machine includes an unloading platform 1, the right end of which is rotatably connected to the ground. The rotatable connection method can be a conventional hinged connection. After the unloading platform 1 is rotated, it is in a tilted state relative to the ground. Connecting parts 2 are provided on both sides of the middle part of the unloading platform 1 for connecting to the lifting cylinders 3 arranged on the ground. The lifting cylinders are used to rotate and tilt the unloading platform relative to the ground. The bottom surface can also be replaced by a base 6, and the base 6 is further fixedly connected to the ground. In this way, the unloading platform 1 and the base 6 form a whole, which is convenient for the overall mobile installation, reduces the steps of separately installing the unloading platform on the ground, and increases the convenience of use. A synchronous stabilization device 19 can also be added between the unloading platform 1 and the base 6 to ensure the stability of the lifting cylinders on both sides, thereby ensuring the stability of the overall structure when the unloading platform 1 is tilted. Furthermore, a buffer box 4 is provided on the unloading platform 1. The buffer box 4 is rotatably connected to the unloading platform 1. After the buffer box 4 is rotated, it remains parallel to the ground. Specifically, the buffer box 4 is rotatably connected to the unloading platform 1 through a slewing support base 12. The slewing support base includes a support, which is fixed to the unloading platform. The support is rotatably connected to an internal gear 13. The upper end of the internal gear 13 is fixedly connected to the buffer box 4. The internal gear 13 is meshed with a drive gear 14, and the drive gear is driven by a drive motor. The drive motor is also fixed on the unloading platform 1. An inlet and outlet for the carbon blocks are provided on the side of the buffer box 4 away from the connection between the unloading platform and the ground. A horizontally arranged pushing device 5 is provided on the rear wall of the buffer box. The pushing device can extend out of the buffer box and abut against the carbon blocks. The pushing device includes a vertically arranged push plate 7 and a horizontally arranged telescopic structure 8 connected to the push plate. The telescopic structure can be a telescopic hydraulic cylinder. A chain conveyor is also provided next to the base. After the buffer box rotates, the inlet and outlet face the chain conveyor.

[0024] Furthermore, a roller structure 9 is fixed on the bottom surface of the buffer box 4. There are multiple roller structures arranged along the length of the buffer box. The roller structure reduces the wear between the carbon blocks and the bottom of the box when loading and unloading, and protects the carbon blocks as much as possible.

[0025] Furthermore, a vertical fixed plate 10 is provided outwardly at the inlet and outlet of the buffer compartment 4, and an adjustment block 11 is provided at the bottom of the fixed plate. The adjustment block is used to contact the bottom surface of the container. The adjustment block includes a block, a threaded rod is provided below the block, and a through hole is provided on the fixed plate. The threaded rod passes through the through hole, and two nuts are screwed onto the threaded rod, and the two nuts are pressed against the upper and lower end surfaces of the through hole. The setting of the block facilitates filling the gap between the container and the buffer compartment, ensuring that the carbon blocks can be discharged smoothly. The block can be adjusted in height to accommodate truck tires of different sizes, that is, to adapt to the bottom surfaces of containers at different heights.

[0026] Furthermore, the buffer chamber 4 is provided with a deflection correction mechanism, comprising a deflection correction plate 15. The deflection correction plate 15 is arranged at an angle, tilting from right to left, away from the pushing device. Two sets of deflection correction plates are arranged symmetrically and fixed to the two vertical side walls of the buffer chamber 4. The deflection correction structure prevents the stacked carbon blocks from shifting and becoming stuck in the buffer chamber during tilted unloading, and overall facilitates the stable unloading of the carbon blocks into the chamber. The deflection correction plate is also provided with a second vertically arranged roller structure to reduce friction with the buffer chamber during automatic feeding of the entire carbon block.

[0027] Furthermore, the unloading platform 1 is equipped with at least two sets of support cylinders 16, symmetrically distributed on both sides of the slewing support seat. A limit portion is provided below the bottom surface of the buffer compartment. The free ends of the support cylinders are connected to limit pins 17, which are inserted into the limit portion. When the unloading platform tilts, the limit pins connect with the limit portion to limit the position, further ensuring the stability of the buffer compartment structure during unloading. After unloading is completed, the support cylinders retract to facilitate the rotation of the buffer compartment, thereby facilitating the transfer of subsequent carbon blocks.

[0028] The coal unloading method using the above structure includes the following steps: a container loaded with neatly stacked coal blocks is placed on the transport structure and reversed to the unloading platform, the lower rear end of the container is against the adjusted adjustment block, the push plate of the pushing device is extended into the container to press against the coal blocks, the unloading platform is tilted to 45°, the push plate is retracted, and the coal blocks slide down into the buffer compartment under the action of gravity, then the unloading platform is reset, the transport structure is withdrawn, the supporting cylinder is retracted, the drive motor is started, and the buffer compartment is rotated so that the inlet and outlet of the buffer compartment face the chain conveyor, and then the pushing device is used to push the coal blocks onto the chain conveyor for transfer.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
