Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to a double-station anode carbon block shifting machine. Background Art

[0002] Anode carbon blocks are essential for electrolytic aluminum production and are the most valuable consumable in the process. To facilitate production, most electrolytic aluminum manufacturers have established anode assembly workshops, where the steel claws on the anode guide rods and the calcined anode carbon blocks are cast together using ferrophosphorus to create new anode carbon blocks. Before assembly, the carbon blocks must be transported to the casting station and then molded together with the anode guide rods. This mold-molding process is quicker, while block shifting takes longer, and this process significantly impacts anode carbon block assembly efficiency.

[0003] Refer to the attached Figure 1 and attached Figure 2 Currently, carbon blocks are moved by a pneumatic cylinder. The pneumatic cylinder 9 pushes the carbon blocks 5 from the carbon block conveyor belt 1 to the casting conveyor line 2. This method has the advantages of simple structure and stable operation. However, its disadvantage is that the cylinder rod retraction process is inefficient. Before the cylinder rod is fully retracted, the carbon blocks behind cannot be delivered, making continuous block movement impossible. This seriously slows down the production efficiency of anode carbon blocks. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a double-station anode carbon block shifting machine, the purpose of which is to achieve continuous shifting and improve the production efficiency of anode carbon blocks.

[0005] Specifically, the present invention adopts the following technical solutions:

[0006] An anode carbon block double-station block-moving machine includes a parallel carbon block conveyor belt and a casting conveyor line. Two rows of rollers are arranged between the carbon block conveyor belt and the casting conveyor line. A cylinder is arranged above each row of rollers. The two cylinders push alternately to push the carbon blocks on the carbon block conveyor belt to the casting conveyor line.

[0007] To further improve the technical solution, there are two casting conveyor lines, and the conveying directions of the two casting conveyor lines are opposite; the two cylinders push alternately to push the carbon blocks on the carbon block conveyor belt to the two casting conveyor lines respectively.

[0008] To further improve the technical solution, the conveying speed of the casting conveyor line is lower than the conveying speed of the carbon block conveyor belt, and a cylinder is provided at one end of the casting conveyor line, which is used to push the carbon blocks on the casting conveyor line laterally to reduce the distance between the carbon blocks.

[0009] To further improve the technical solution, the carbon block conveyor belt and the casting conveyor line are plate chain conveyor belts or powered conveyor rollers.

[0010] To further improve the technical solution, a pushing plate is connected to the telescopic end of the cylinder.

[0011] After implementing the above technical solution, the beneficial effects produced by the utility model are:

[0012] Existing carbon block pushers have idle time. Before the cylinder is fully retracted, the carbon blocks cannot be conveyed forward. Each cylinder takes 4-5 minutes to push each carbon block. This carbon block pusher adopts a double-station continuous block pushing method. The two cylinders push the blocks alternately. The block pushing process does not hinder the transportation of carbon blocks on the carbon block conveyor belt. Each cylinder pushes a carbon block in just 2.5 minutes, significantly shortening the block pushing time and improving the production efficiency of anode carbon blocks.

[0019] The following describes preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that, in the description of the present invention, terms such as "front," "rear," "up," "down," "left," "right," "vertical," "horizontal," "inside," and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can mean fixed, detachable, or integral; mechanical or electrical; direct, indirect through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] Example 1: Refer to the attached Figure 3-4 A double-station anode carbon block machine includes a carbon block conveyor belt 1 and a casting conveyor line 2 arranged in parallel. The carbon block conveyor belt 1 and the casting conveyor line 2 can adopt plate chain conveyor belts or powered conveyor rollers.

[0021] Two rows of unpowered rollers are arranged between the carbon block conveyor belt 1 and the casting conveyor line 2, namely the unpowered roller A3 and the unpowered roller B4. A cylinder A6 is arranged above the unpowered roller A3, and a cylinder B7 is arranged above the unpowered roller B4. Pushing plates for pushing carbon blocks 5 are connected to the telescopic ends of cylinders A6 and B7.

[0022] During operation, the carbon block conveyor belt 1 conveys the carbon blocks 5 to the left, and the casting conveyor line 2 conveys the carbon blocks 5 to the right. The conveying speed of the carbon block conveyor belt 1 is the same as the conveying speed of the casting conveyor line 2. Cylinder A6 and cylinder B7 push alternately to push the carbon blocks 5 on the carbon block conveyor belt 1 to the casting conveyor line 2.

[0023] Refer to the attached Figure 3 The cylinder B7 extends and pushes the carbon blocks 5 on the carbon block conveyor belt 1 to the casting conveyor line 2 through the unpowered roller B4. During the extension and retraction process of the cylinder B7, the carbon blocks 5 on the carbon block conveyor belt 1 are not hindered from moving to the left.

[0024] Refer to the attached Figure 4Then, the cylinder A6 begins to extend, and the cylinder B7 begins to retract. The cylinder A6 pushes the carbon blocks 5 on the carbon block conveyor belt 1 to the casting conveyor line 2 through the unpowered roller A3.

[0025] Comparison reference Figure 1 and attached Figure 3 Attached Figure 1 The process of the middle cylinder retracting is ineffective. Before the cylinder is fully retracted, the carbon blocks 5 at the rear cannot be delivered, and continuous block shifting cannot be achieved. It takes 4-5 minutes for each cylinder to push each carbon block 5. This block shifting machine adopts a double-station block shifting method. The two cylinders shift the blocks alternately. During the block shifting process, the carbon blocks 5 are not hindered from being transported on the carbon block conveyor belt 1. It only takes 2.5 minutes for each cylinder to push each carbon block 5, greatly improving the block shifting efficiency.

[0026] Example 2: Refer to the attached Figure 5 The present embodiment differs from the embodiment 1 in that there are two casting conveyor lines 2, and the conveying directions of the two casting conveyor lines 2 are opposite. The two cylinders push alternately, pushing the carbon blocks 5 on the carbon block conveyor belt 1 to the two casting conveyor lines 2 respectively.

[0027] Specifically, the cylinder A6 pushes the carbon block 5 onto the casting conveyor line 2 on the left side through the unpowered roller A3, and the cylinder B7 pushes the carbon block 5 onto the casting conveyor line 2 on the right side through the unpowered roller B4.

[0028] Example 3: Refer to the attached Figure 6 This embodiment differs from Example 1 in that the conveying speed of the casting conveyor line 2 is lower than that of the carbon block conveyor belt 1. A cylinder C8 is provided at one end of the casting conveyor line 2 to laterally push the carbon blocks 5 on the casting conveyor line 2, thereby reducing the spacing between the carbon blocks 5. This design can shorten the length of the casting conveyor line 2, allowing the carbon blocks 5 on the casting conveyor line 2 to be arranged more densely, facilitating the casting of ferrophosphorus.

[0029] Parts not described in detail are prior art. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
