Its roasting and startup process has an important impact on the production efficiency and product quality of electrolytic aluminum. In the roasting and startup process of aluminum electrolytic cell, the laying of coke particles is a crucial step. Coke particles are the main heat carrier and filling material in the roasting process of electrolytic cell.

[0003] With the continuous development of the electrolytic aluminum industry, the requirements for the electrolytic cell roasting startup process are becoming higher and higher. The traditional coke particle laying method has many shortcomings. Workers need to put the coke particles into the aluminum electrolytic cell first, and then use a push plate to spread the coke particles. The manual laying method in the aluminum electrolytic cell is not only labor-intensive, but also the workers operate inside the aluminum electrolytic cell and do not observe comprehensively. The laying height and laying surface are often difficult to achieve the ideal state, which will not only lead to unstable electrolytic cell roasting quality, but may also affect the production efficiency and product quality of electrolytic aluminum.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] A coke granule laying device for an aluminum electrolytic cell, as shown in the attached Figure 1-8 As shown, it includes a main frame groove 1 and a winding roller 10. A receiving groove 6 is arranged below the main frame groove 1. The bottom surface of the receiving groove 6 is fixedly connected to a discharge groove 7. The shape of the discharge groove 7 is trapezoidal, so that the discharge amount can be more easily controlled when laying coke particles.

[0032] A limiting mechanism 8 is arranged below the discharge chute 7, and the limiting mechanism 8 includes a baffle plate 803 and a connecting plate 805, the baffle plate 803 is fixedly connected to the connecting plate 805, an inner shaft 806 is fixedly connected to the interior of the connecting plate 805, both ends of the inner shaft 806 extend out of the interior of the connecting plate 805, and two torsion springs 807 are sleeved on the outer surface of the inner shaft 806, and the torsion springs 807 are sleeved on the outside of the portion extending from the connecting plate 805.

[0033] The upper surface of the baffle plate 803 contacts the bottom surface of the discharge trough 7, and the outer surface of the inner shaft 806 is rotatably connected to two fixed plates 804. The two fixed plates 804 are fixedly connected to the discharge trough 7 at one end close to the discharge trough 7, and the two ends of the torsion spring 807 are respectively fixedly connected to the outer surfaces of the fixed plate 804 and the connecting plate 805. By using the elastic force of the torsion spring 807, the connecting plate 805 and the baffle plate 803 can maintain the position of blocking the discharge trough 7.

[0034] The outer surface of the connecting plate 805 is fixedly connected to a slope plate 802, and the outer surface of the slope plate 802 is fixedly connected to a pull ring 801. The slope plate 802 itself has a curvature, so that when the pull ring 801 is pulled, the slope plate 802 and the shielding plate 803 can be rotated, so that the shielding plate 803 releases the limit on the discharge trough 7.

[0035] A group of grip rods 9 are installed on the outer surface of the winding roller 10, and a pull rope 16 is wound on the outer surface of the winding roller 10. By using the grip rod 9, the winding roller 10 can be easily rotated. When the worker holds the grip rod 9, the pull rope 16 can be limited to prevent the winding roller 10 from moving.

[0036] The inner wall of the winding roller 10 is rotatably connected with a center column 11 , and the center column 11 is fixedly connected to the main frame slot 1 . The winding roller 10 can be supported by the center column 11 .

[0037] A positioning rod 13 is fixedly connected to the right side of the accommodating groove 6, and a first pulley 12 is fixedly connected to the outer surface of the positioning rod 13. By using the cooperation of the first pulley 12 and the positioning rod 13, the pull rope 16 can be guided. A mounting groove 14 is fixedly connected to the right side of the accommodating groove 6, and two second pulleys 15 are installed inside the mounting groove 14. The pull rope 16 passes through the two second pulleys 15 and contacts with the two second pulleys 15, and the pull rope 16 contacts with the first pulley 12. One end of the pull rope 16 is arranged inside the pull ring 801. By using two second pulleys 15, it can be ensured that the pull rope 16 can vertically pull the pull ring 801 to avoid the pull rope 16 from being skewed, resulting in the inability to pull the pull ring 801.

[0038] The inner wall of the main frame slot 1 is rotatably connected to a threaded long rod 3, and the outer surface of the threaded long rod 3 is threadedly connected to a main supporting slider 4, and the outer surface of the main supporting slider 4 is slidably connected to the inner wall of the main frame slot 1. The bottom surface of the main supporting slider 4 is fixedly connected to two hanging plates 5, and the bottom surfaces of the two hanging plates 5 are fixedly connected to the upper surface of the receiving slot 6. The front end of the threaded long rod 3 is fixedly connected to a turntable 2. By using the turntable 2, it is convenient for workers to rotate the threaded long rod 3, so as to adjust the positions of the main supporting slider 4, the hanging plates 5, the receiving slot 6 and the discharge slot 7, so that the discharge slot 7, which is smaller in width than the aluminum electrolytic cell, can fully lay coke particles on the aluminum electrolytic cell.

[0039] When the position of the discharge trough 7 is adjusted, the worker does not hold the handle 9, and the pull rope 16 will be unwound on the outer surface of the winding roller 10. Therefore, when the position of the discharge trough 7 is adjusted, the limiting mechanism 8 will not release the limit on the discharge trough 7, and the coke particles will not be discharged.

[0040] Two support blocks 17 are fixedly connected to the bottom surface of the main frame tank 1, and moving wheels 18 are fixedly connected to the bottom surfaces of the two support blocks 17. By using the two support blocks 17 and the moving wheels 18, the entire device can be easily moved outside the aluminum electrolytic cell.

[0041] Two positioning plates 19 are fixedly connected to the bottom surface of the main frame slot 1, and side guide mechanisms 20 are arranged inside the two positioning plates 19. The side guide mechanism 20 includes a threaded short rod 2002 and a support plate 2003. A group of balls 2004 are installed inside the support plate 2003. The balls 2004 are installed on a side close to the aluminum electrolytic cell. The balls 2004 can roll inside the support plate 2003. The outer surface of the threaded short rod 2002 is threadedly connected to the positioning plate 19. The end of the threaded short rod 2002 close to the support plate 2003 is rotatably connected to the support plate 2003. The end of the threaded short rod 2002 away from the support plate 2003 is fixedly connected with a holding plate 2001. By screwing the holding plate 2001, the support plate 2003 can be moved, so that the balls 2004 are close to the outer surface of the aluminum electrolytic cell.

[0042] Two guide rods 2005 are fixedly connected to one side of the support plate 2003 close to the holding plate 2001. The outer surfaces of the two guide rods 2005 are slidably connected to the inner wall of the positioning plate 19. By using two guide rods 2005, rotation of the support plate 2003 can be avoided when it moves.

[0043] An anti-blocking mechanism 21 is arranged inside the discharge chute 7, and the anti-blocking mechanism 21 includes a motor 2101 and two mounting rings 2105. The outer surfaces of the two mounting rings 2105 are fixedly connected with a group of spreading plates 2106. The spreading plates 2106 are arranged at the discharge port of the discharge chute 7. When they rotate, they can prevent the coke particles inside the discharge chute 7 from forming an arch bridge effect and being unable to discharge the material, resulting in uneven laying of the coke particles.

[0044] The anti-blocking mechanism 21 also includes two synchronous wheels 2102. The output end of the motor 2101 is fixedly connected to one of the synchronous wheels 2102. The two synchronous wheels 2102 are connected through a synchronous belt 2103. The right ends of the two synchronous wheels 2102 are fixedly connected to a supporting rotating rod 2104. The outer surfaces of the two supporting rotating rods 2104 are rotatably connected to the inner wall of the discharge trough 7. The outer surfaces of the two supporting rotating rods 2104 are fixedly connected to two mounting rings 2105 respectively. The two push-dispersing plates 2106 can be driven by the same power source, which is more energy-efficient.

[0045] The outer surface of the motor 2101 is fixedly connected to a mounting seat 2107, the outer surface of the mounting seat 2107 is fixedly connected to a mounting plate 2108, the mounting plate 2108 is fixedly connected to the outer surface of the discharge trough 7, and the output end of the motor 2101 passes through the mounting seat 2107 and does not contact the mounting seat 2107 to avoid affecting the rotation of the output shaft of the motor 2101.

[0046] Working principle: When the coke particles of the aluminum electrolytic cell need to be laid, first place the device above the aluminum electrolytic cell, so that the moving wheel 18 is on the upper surface of the aluminum electrolytic cell. By rotating the holding plate 2001, the threaded short rod 2002 can be driven to rotate, which can drive the support plate 2003 to move toward the direction close to the outer surface of the aluminum electrolytic cell, so that a group of balls 2004 can contact the side outer surface of the aluminum electrolytic cell. By using the grip 9, the winding roller 10 can be easily rotated, so that the pull rope 16 can be reeled in. The pull rope 16 can pull the pull ring 801, the inclined plate 802, the baffle plate 803 and the connecting plate 805 to rotate around the center of the inner shaft 806, so that the baffle plate 803 no longer limits the through hole at the bottom of the discharge trough 7, and the coke particles will fall into the interior of the aluminum electrolytic cell. When the worker does not hold the grip 9 with his hands, the elastic force of the torsion spring 807 can drive the connecting plate 805 and the baffle plate 803 to reset, so that the coke particles will no longer be discharged from the interior of the discharge trough 7, thereby realizing convenient control of the coke particle spreading. By starting the motor 2101, the synchronous wheel 2102 can be driven to rotate. Under the transmission action of the synchronous belt 2103, the two synchronous wheels 2102 can rotate synchronously. The two synchronous wheels 2102 can drive the two supporting rotating rods 2104, the mounting ring 2105 and the two sets of pushing plates 2106 to stir the coke particles inside the discharge trough 7, thereby avoiding the coke particles from forming an arch bridge effect inside the discharge trough 7 and being unable to be discharged.
