Description

Technical Field

[0001] The invention relates to the technical field of anode production equipment for carbon aluminum, and in particular to an automatic paperboard adding device in an anode tank for aluminum electrolysis and a working method thereof. Background Art

[0002] In the process of aluminum electrolysis, in order to remove the gas at the bottom of the aluminum anode carbon block in time and improve the current efficiency, it is currently required to open grooves at the bottom of the anode (generally two grooves are opened longitudinally for each carbon block). The raw anode carbon blocks for aluminum are made of calcined petroleum coke and coal tar. After the raw anode carbon blocks are slotted and roasted at high temperature, the grooves are easily deformed and damaged. For this reason, cardboard needs to be stuffed in the groove before the raw anode carbon blocks are loaded into the furnace for roasting. At present, the operation of stuffing cardboard in the groove is done manually, requiring two people per shift, with a large workload and a long time. The overhead crane starts and stops frequently, the labor efficiency is low, and there are safety hazards.

[0003] The Chinese utility model patent with the publication number CN208343010U discloses a new type of industrial processor for filling bowls before pre-baked anode baking, including a bracket, an electric push rod and a distribution box. A fixed disc is welded on one side of the upper end of the right side of the bracket, one end of the electric push rod is threadedly connected with a connecting sleeve, and the electric push rod is electrically connected to the distribution box, one side of the connecting sleeve is threadedly connected with a cutting disc, a support card is provided on the right side of the front of the electric push rod, and a fixing card is provided on the left side of the front of the electric push rod. Through the electric push rod and the cutting disc, people do not need to manually process the paper pad, thereby increasing the output and efficiency of the paper pad, and can avoid that the specifications of the paper pad cannot be kept at the same specification when the paper pad is manually processed. The first limit disc and the second limit disc are provided to fix the paper pad to be processed, so that the specifications of the paper pad are prevented from changing during processing. It is suitable for the field of pre-baked anode baking and has good development prospects.

[0004] This new type of industrial processor for filling bowls before baking anodes can realize the automated production of paper pads, but it does not solve the technical problem that the operation of stuffing cardboard into the slot is still done manually. Summary of the invention

[0049] A push mechanism, which is installed in the guide groove 8 and pushes the paperboard 6 placed in the guide groove 8 into the slot of the green anode carbon block 1 on the conveying mechanism;

[0051] A control unit is electrically connected to the conveying mechanism, the pushing mechanism, the ejecting mechanism and the detector respectively.

[0052] The automatic paperboard adding device in the anode tank for aluminum electrolysis is composed of a conveying mechanism, a guide groove 8, a paperboard box 4, a pushing mechanism, a pushing mechanism, a detector, and a control unit. The conveying mechanism can continuously transport the raw anode carbon block 1, the guide groove 8 extends toward the bottom of the raw anode carbon block 1 on the conveying mechanism, the paperboard box 4 contains a plurality of paperboards 6 and is installed on the guide groove 8 in a manner connected with the guide groove 8, the pushing mechanism pushes the paperboards 6 in the paperboard box 4 into the guide groove 8, the pushing mechanism is installed in the guide groove 8 and pushes the paperboards 6 placed in the guide groove 8 into the slot of the raw anode carbon block 1 on the conveying mechanism, and the detector is close to the conveying mechanism and is used to detect the position of the raw anode carbon block 1. The control unit is electrically connected to the conveying mechanism, the pushing mechanism, the pushing mechanism, the pushing mechanism, and the detector respectively.

[0053] The automatic paperboard adding device in the anode tank for aluminum electrolysis has the following working steps:

[0054] (1) Put enough cardboard into the cardboard box;

[0055] (2) The pushing mechanism pushes the cardboard into the guide groove 8;

[0056] (3) The green anode carbon block 1 is transported to the target position by the conveying mechanism;

[0057] (4) The detector detects that the raw anode carbon block 1 is in place, and the conveying mechanism stops;

[0058] (5) The push mechanism pushes the paperboard in the guide groove 8 into the slot of the raw anode carbon block 1 on the conveying mechanism;

[0059] (6) The push mechanism returns to its original position, and the push mechanism pushes the next cardboard 6 into the guide groove 8;

[0060] (7) The conveying mechanism rotates, and the green anode carbon block 1 is delivered to the marshalling station;

[0061] (8) The above steps (3) to (7) are repeated in a cycle.

[0062] Specifically, the conveying mechanism is a roller conveyor 2, and the green anode carbon blocks 1 can be continuously conveyed on the roller conveyor 2. The guide groove 8 extends toward the roller conveyor 2. Figure 1 As shown, the roller conveyor 2 is placed horizontally, and the guide groove 8 extends vertically toward the roller conveyor 2. When the green anode carbon block 1 stops on the roller conveyor 2, the guide groove 8 can just face the bottom of the green anode carbon block 1. A plurality of cardboards 6 are contained in the cardboard box 4, and the cardboard box 4 is installed on the guide groove 8 in a manner connected to the guide groove 8.

[0063] The pushing mechanism includes at least one pushing cylinder 3 and a solenoid valve thereon, the solenoid valve on the pushing cylinder 3 is electrically connected to the control unit, and the free end of the piston rod in the pushing cylinder 3 is used to push the cardboard 6 in the cardboard box 4. Preferably, as Figure 2 As shown, there are multiple pushing cylinders 3, and these pushing cylinders 3 are symmetrically arranged along the guide groove 8 on both sides of the cardboard box 4. In order to facilitate pushing the cardboard 6, it is further improved that the free end of the piston rod in each pushing cylinder 3 is hinged with a pushing plate 5 that contacts the cardboard 6 in the cardboard box 4. The piston rod in the pushing cylinder 3 is extended and retracted in the horizontal direction. When the piston rod in the pushing cylinder 3 is pushed out, the pushing plate 5 on the piston rod presses the cardboard 6 in the cardboard box 4 and pushes the cardboard 6 into the guide groove 8.

[0064] The ejection mechanism includes at least one ejection cylinder 7 and a solenoid valve thereon. In this embodiment, two ejection cylinders 7 are preferably provided. The solenoid valves on each ejection cylinder 7 are electrically connected to the control unit. The free end of the piston rod in the ejection cylinder 7 pushes the paperboard 6 placed in the guide groove 8 into the groove of the green anode carbon block 1 on the roller conveyor 2. Figure 1 As shown, the piston rod in the ejection cylinder 7 is extended and retracted along the guide groove 8. Preferably, the free end of the piston rod in the ejection cylinder 7 is hinged with an ejection plate (not shown) in contact with the paperboard 6 in the guide groove 8. When the piston rod in the ejection cylinder 7 is pushed out, the ejection plate on the piston rod presses against the paperboard 6 in the guide groove 8 and pushes the paperboard 6 into the slot of the green anode carbon block 1 on the roller conveyor 2.

[0065] The detector is preferably an infrared sensor, which detects the position of the green anode carbon block 1 by infrared rays. The control unit is preferably a programmable controller, which is electrically connected to the roller conveyor 2, the solenoid valve on the push cylinder 3, the solenoid valve on the push cylinder 7, and the infrared sensor.

[0066] In addition, position sensors electrically connected to the programmable controller are provided at the target position of the raw anode carbon block 1 (the position where the raw anode carbon block 1 stops on the roller conveyor 2 and faces the guide groove 8), the long limit and the short limit of the piston rod in the push cylinder 7, and a sufficient amount of spare cardboard 6 can be stored in the cardboard box 4 in advance. The piston rod of the pushing cylinder 3 can drive the pushing plate 5 to press the cardboard 6 in the cardboard box 4, and when the piston rod of the pushing cylinder 3 is retreated, the next cardboard 6 can be pushed into the spare position (in the guide groove 8), so as to fully utilize the turning time of the previous raw anode carbon block 1, and the push cylinder 7 drives the piston rod to push the cardboard 6 in the guide groove 8 into the slot of the raw anode carbon block 1 and retreat it in time.

[0067] The specific working method and steps of the automatic paperboard adding device in the anode tank for aluminum electrolysis are as follows:

[0068] (1) Put enough cardboard 6 into the cardboard box 4;

[0069] (2) The push cylinder 3 pushes the pressing paperboard 6 into the guide groove 8;

[0070] (3) The green anode carbon block 1 is transported to the target position by the roller conveyor 2;

[0071] (4) The detector detects that the green anode carbon block is in place, and the roller conveyor 2 stops;

[0072] (5) The piston rods of the two ejection cylinders are ejected simultaneously, driving the ejection plate to push the two paperboards in the guide groove 8 into the slot of the raw anode carbon block 1 on the roller conveyor 2;

[0073] (6) The two ejection cylinders 7 drive their respective ejection plates back to their original positions, while the piston rod in the push cylinder 3 drives the push plate 5 to push the next paperboard 6 into the guide groove 8;

[0074] (7) The roller conveyor 2 rotates, and the green anode carbon blocks 1 are sent to the marshalling station;

[0075] (8) The above steps (3) to (7) are performed in a cycle. When there is no cardboard in the cardboard box 4, a signal is sent at the position of the pressing plate pressing the cardboard to remind the user to load the cardboard again.

[0076] The automatic paperboard adding device in the anode tank for aluminum electrolysis and the working method thereof in this embodiment have the following beneficial effects:

[0077] 1. The cardboard adding operation is completed by machine, which reduces the unsafe factors of manual operation.

[0078] 2. No manual operation is required, which greatly reduces labor intensity.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
