Description

Technical Field

[0001] The invention relates to the technical field of manufacturing anode carbon blocks for electrolytic aluminum, in particular to a raw anode bowl charging and covering device. Background Art

[0002] Anode carbon blocks are an indispensable and important part in the production process of electrolytic aluminum. Their quality directly affects the production of electrolytic aluminum, and they are easily damaged due to their large consumption. Anode carbon blocks are called green anodes before roasting, and have a rectangular shape. Four bowl-shaped countersunk holes of equal volume are arranged on the top, which is called the anode bowl. Adding fillers to the anode bowl is to protect the anode bowl during the roasting process to avoid quality problems such as cracks and deformation. The filler is a mixture of sawdust and calcined coke in a certain proportion. It is dry and fluffy, has poor fluidity, and is easy to dust. In order to prevent the filler from leaking out during the roasting process of the green anode, a cardboard cover with several teeth on the outer ring needs to be added to the anode bowl.

[0003] The raw anode bowl is usually filled in the anode production plant. An overhead crane places the raw anodes neatly on the ground, and then all filling operations are completed manually. The labor intensity is high and the working environment is poor. Since it is operated based on experience and feeling, the filling amount is difficult to control, and the cardboard cover is easy to fall off or leak, resulting in a low yield rate of anode carbon blocks after roasting. Summary of the invention

[0013] Further, the capping and pressing device includes a chassis connected to the constant-volume feeder. The chassis is provided with a cover outlet and a paper cover cylinder at intervals, and hard paper covers are stacked in the paper cover cylinder. The cover outlet is aligned with the discharge pipe opening; a pneumatic push plate is provided on the chassis to push the lowermost hard paper cover in the paper cover cylinder into the cover outlet.

[0014] Further, the capping and pressing device further includes a pressing cylinder. One end of the pressing cylinder is connected to the bottom of the constant-volume feeder, and the other end is connected with a sleeve for pressing the hard paper cover into the anode bowl opening.

[0036] Further, as Figure 3 shown, the stirring hopper 1 includes a hopper 1-1 and a hopper support 1-4 for supporting the hopper 1-1. The lower ends of the hopper supports 1-4 are arranged on both sides of the frame of the rolling platform; a flange hole plate 1-3 is provided at the bottom of the hopper 1-1, and a plurality of circular discharge ports 1-5 are provided on the flange hole plate 1-3.

[0037] Further, as Figure 3 shown, a stirring mechanism 1-2 is provided inside the hopper 1-1. The stirring mechanism 1-2 includes a stirring motor arranged outside the hopper 1-1 and a stirring shaft arranged inside the hopper 1-1. The stirring shaft is connected to the output shaft of the stirring motor, and stirring blades are provided on the stirring shaft.

[0038] Embodiment 2 is different from Embodiment 1 in that, as Figure 4 and Figure 5 shown, the constant-volume feeder 2 includes a tank body 2-1 and a movable material box 2-3. The top of the tank body 2-1 is connected to the flange hole plate 1-3 of the stirring hopper 1 through a flange plate. The movable material box 2-3 is movably arranged inside the tank body 2-1. A discharge pipe opening 2-11 is provided at the bottom of the tank body 2-1. The number of the discharge pipe openings 2-11 is the same as that of the circular discharge ports 1-5 on the flange hole plate 1-3, and the discharge pipe openings 2-11 are staggered from the circular discharge ports 1-5. The movable material box 2-3 can be moved to positions where it is aligned and communicated with the discharge pipe openings 2-11 and the circular discharge ports 1-5 respectively. A cylinder 2-2 is provided on the tank body 2-1. An end plate is provided on one side of the tank body 2-1 close to the cylinder 2-2 for supporting the cylinder 2-2. The fixed end of the cylinder 2-2 is connected to the end plate of the tank body 2-1 through a cylinder seat. The telescopic end of the cylinder 2-2 is connected to the movable material box 2-3 for pushing the movement of the movable material box 2-3 so that the constant-volume cylinder 2-31 is aligned with the outlet of the stirring hopper 1, that is, the circular discharge port 1-5 or the discharge pipe opening 2-11 respectively.

[0039] Embodiment 3 is different from Embodiment 2 in that, as Figure 5As shown in the figure, the movable cartridge 2-3 includes a number of constant-volume cartridges 2-31, and the number of constant-volume cartridges 2-31 are connected by a connecting plate 2-32. The outer side of the connecting plate 2-32 fits and is slidably mated with the inner side of the above-mentioned flange plate. A connecting plate is also provided between the bottoms of the number of constant-volume cartridges 2-31 to prevent interference between the lower ends of the constant-volume cartridges 2-31 and the discharge pipe orifice 2-11 during the sliding process of the movable cartridge 2-3.

[0040] In addition, as Figure 6 shown in the figure, a slider and a slideway 2-4 are provided between the outer side of the movable cartridge 2-3 and the inner side of the tank body 2-1 to facilitate the sliding of the movable cartridge 2-3.

[0041] During use, in the initial state, the constant-volume cartridge 2-31 is centered with the circular discharge port 1-5 of the flange orifice plate 1-3, and the material in the mixing hopper 1 enters the constant-volume cartridge 2-31 to fill the constant-volume cartridge 2-31 with filling material. The telescopic movement of the piston rod of the air cylinder 2-2 controls the constant-volume cartridge 2-31 of the movable cartridge 2-3 to switch the centered position between the circular discharge port 1-5 and the discharge pipe orifice 2-11 of the tank body 2-1, so that the constant-volume cartridge 2-31 is aligned with the discharge pipe orifice 2-11, and the filling material is injected into the anode bowl through the discharge pipe 2-11.

[0042] Embodiment 4, the difference from Embodiment 3 is that, as Figures 7 - 9 shown in the figure, the capping and pressing device 3 includes a capping mechanism. The capping mechanism includes a chassis 3-3 connected to the tank body 2-1. A number of lid outlets 3-10 and a number of paper lid cylinders 3-1 are provided at intervals on the chassis 3-3. The number of lid outlets 3-10 and paper lid cylinders 3-1 is the same as that of the discharge pipe orifices 2-11 and the flange orifice plate 1-3. And a number of hard paper lids 3-2 are stacked in the paper lid cylinder 3-1, and the lid outlet 3-10 corresponds to the discharge pipe orifice 2-11; A pneumatic push plate 3-4 is provided on the chassis 3-3 to push the lowermost hard paper lid 3-2 in the paper lid cylinder 3-1 into the lid outlet 3-10 so that the hard paper lid 3-2 is aligned with the anode bowl 5-1. Among them, the pneumatic push plate 3-4 is controlled by a push plate air cylinder 3-11 provided on the chassis 3-3.

[0043] Embodiment 5, the difference from Embodiment 4 is that a counterweight 3-8 is placed on the upper end of the hard paper lid 3-2 in the paper lid cylinder 3-1, so that after the lowermost hard paper lid 3-2 is pushed out, the next hard paper lid 3-2 can move down smoothly.

[0044] Embodiment 6, the difference from Embodiment 5 is that, as Figure 10As shown, the capping and pressing device 3 further includes a pressing mechanism. The pressing mechanism includes a pressing cylinder 3-5. The fixed end of the pressing cylinder 3-5 is connected to the bottom of the constant-volume feeder 2, and the movable end is connected with a pressing assembly for pressing the cardboard cover 3-2 into the mouth of the anode bowl 5-1. The pressing assembly includes a number of sleeves 3-6, and the number of sleeves 3-6 is the same as that of the cover outlet 3-10 and the discharge pipe orifice 2-11. The upper half of the sleeve 3-6 is sleeved outside the discharge pipe orifice 2-11.

[0045] Example 7, the difference from Example 6 is that, as Figure 9 and Figure 10 shown, a positioning ring 3-7 is provided on the chassis 3-3. The positioning ring 3-7 is concentric with the paper cover cylinder 3-1. The bottom of the paper cover cylinder 3-1 extends into the upper part of the positioning ring 3-7, and the bottom of the paper cover cylinder 3-1 is supported on the positioning ring 3-7 by a support rod. There is a gap between the bottom of the paper cover cylinder 3-1 and the chassis 3-3, and a cardboard cover 3-2 can pass through this gap. An opening for the pneumatic push plate 3-4 to pass through is provided on one side of the positioning ring 3-7 away from the cover outlet 3-10, which is convenient for the pneumatic push plate 3-4 to push out the lowermost cardboard cover 3-2 in the paper cover cylinder 3-1. A cardboard cover outlet for a cardboard cover 3-2 to pass through is provided on the side of the positioning ring 3-7 close to the cover outlet 3-10. A retaining bar 3-9 is further provided on the chassis 3-3. The retaining bar 3-9 includes a semi-circular arc retaining bar and a straight retaining bar. The semi-circular arc retaining bar and the straight retaining bar surround the side of the cover outlet 3-10 away from the positioning ring 3-7, and the straight retaining bar is connected between the two ends of the semi-circular arc retaining bar and the side of the cardboard cover outlet of the positioning ring 3-7.

[0046] Example 8, the difference from Example 7 is that, as Figure 10 shown, an internal pressing member 3-61 is provided on the inner side of the bottom of the sleeve 3-6, and an outer pressing plate is provided on the outer side. It is convenient to better press the cardboard cover 3-2 into the anode bowl 5-1 through the internal pressing member 3-61 and the outer pressing plate. The wall thickness of the internal pressing member 3-61 is relatively thin and is vertically arranged in the sleeve 3-6 without hindering the feeding process.

[0047] Example 9, the difference from Example 1 is that, as Figure 11 shown, the carbon block conveying platform 4 is a rolling platform; the rolling platform includes a frame 4-3, rollers 4-2 arranged on the frame 4-3, a power mechanism 4-1 for driving the rollers 4-2 to rotate, etc. In addition to the function of conveying the anode carbon block, the rolling platform can also adjust the position of the anode carbon block during the conveying process to align the anode bowl with the discharge pipe orifice.

[0048] In use, after the filler is added into the anode bowl through the discharge pipe orifice 2-11, the pneumatic push plate 3-4 pushes out the lowermost hard paper cover 3-2 in the paper cover cylinder 3-1 to the cover outlet 3-10, and the stop bar 3-9 on the chassis 3-3 blocks the hard paper cover 3-2 from shifting or rotating. Then, the piston rod of the pressing cylinder 3-5 extends, and the sleeve 3-6 drops along the discharge pipe until the hard paper cover 3-2 is pressed into the anode bowl orifice to seal the bowl orifice. The pneumatic push plate 3-4 and the pressing cylinder 3-5 reset, and the hard paper cover 3-2 in the paper cover cylinder 3-1 automatically moves downward, completing the operations of covering and pressing. The rolling platform sends out the carbon block that has completed the feeding and covering and conveys the new green anode carbon block to the position under the constant-volume feeder 2, and continues the above operations.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
