Description

Technical Field

[0001] This utility model relates to the field of aluminum anode production technology, and in particular to a device that integrates automatic sampling, reduction, sample collection and waste disposal for aluminum anode production. Background Art

[0002] Currently, in aluminum anode production, calcined coke accounts for 75%-85%, with a calcination input-output ratio of approximately 1.25, meaning that the input of pre-calcined coke is about 125% of the output of calcined coke. At present, sampling of pre- and post-calcined coke is done manually, specifically on the conveyor belt. The samples taken represent pre- or post-calcined coke at a specific point in time. Due to limitations in manpower, the test results only represent the condition of pre- or post-calcined coke within a certain time range. If abnormal test results are found, resampling and testing are required. This can lead to instability in the production process of pre- and post-calcined coke, significant fluctuations in test results, and increased labor intensity and safety risks for employees.

[0003] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a device suitable for the production of aluminum anodes that integrates automatic sampling, reduction, sample collection, and waste disposal. Utility Model Content

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] See Figures 1 to 2 As shown;

[0037] This embodiment discloses a device that integrates automatic sampling, reduction, sample collection, and waste disposal. The device includes:

[0038] 10 material conveyor belts;

[0039] A receiving channel 11, integrated into one side of the material conveyor belt 10, is equipped with a divider. The lower part of the receiving channel 11 has a collection channel 7 and a waste channel 5, both connected to the divider.

[0040] The sampling assembly has a sampling shovel 1 that is driven to rotate by a drive structure, and the sampling shovel 1 is capable of sampling material at a specified time and position on the material conveyor belt 10 and putting it into the receiving channel 11.

[0041] The material entering the receiving channel 11 is distributed by the internal divider, with part entering the collecting channel 7 and part entering the waste channel 5.

[0042] Specifically, this embodiment discloses an automated device that integrates automatic sampling, reduction, collection, and disposal, and is centrally controlled by a control component. First, the material is transported via a material conveyor belt 10. A drive structure rotates the sampling shovel shaft 6, and a sampling shovel 1 is welded and fixed to the shaft 6. The drive structure rotates the shovel 1 to scoop up the material on the material conveyor belt 10 at that point, and after rotating once, it is thrown into the receiving channel 11 of this embodiment. A reduction device is installed in the receiving channel 11. Due to the short sampling time interval, the reduction device can be set as a six-part or eight-part device, collecting one part as a sample and discarding the rest. The reduction device in the receiving channel 11 is connected to a collection channel 7 and a disposal channel 5. The collection channel 7 collects a portion of the material, and the excess material is returned to the material conveyor belt 10 via the disposal channel.

[0043] Preferably, the sampling component in this embodiment has a control component, which is used to control the operation of the drive structure to drive the sampling shovel 1 to move.

[0044] Preferably, the drive structure of this embodiment includes a motor 801 and a reducer 802 connected to the output end of the motor 801. The output end of the reducer 802 is connected to a sampling shovel shaft 6. The sampling shovel 1 is welded and fixed to the middle position of the sampling shovel shaft 6, and the position of the sampling shovel 1 matches the receiving channel 11. This embodiment further defines the composition of the drive structure. After the motor 801 drives the reducer 802, it drives the sampling shovel shaft 6 to rotate, thereby driving the sampling shovel 1 to rotate. One rotation can scoop up the material on the material conveyor belt 10 and stop after rotating to the correct position. The material is then put into the receiving channel 11 by inertia, and finally, the material is divided and discharged in the divider, and excess material is recovered.

[0045] Preferably, the end of the sampling shovel 1 in this embodiment is a shovel head with an arc-shaped groove structure;

[0046] The motor 801 and the reducer 802 drive the sampling shovel 1 to rotate via the sampling shovel shaft 6 and scoop up the material on the material conveyor belt 10 and put it into the receiving channel 11.

[0047] Preferably, the control components in this embodiment include a PLC controller 3, a timer 2, and a limit switch 4; wherein, the PLC controller 3 is used to control the operation of the motor 801, and the timer 2 and the limit switch 4 communicate with the PLC controller 3.

[0048] When the sampling shovel 1 rotates to the position of the limit switch 4, the limit switch 4 sends a signal to the PLC controller 3, and the PLC controller 3 drives the motor 801 to stop running.

[0049] This embodiment further defines the composition of the control component, which includes a PLC controller 3, a timer 2, and a limit switch 4. Both the timer 2 and the limit switch 4 are electrically connected to the PLC controller 3 and have corresponding logic rules set. This allows the timer 2 to periodically start the motor 801 and drive the sampling shovel 1 to rotate according to the time setting rules. When the sampling shovel 1 reaches the position of the limit switch 4, the limit switch 4 sends a stop signal to the PLC controller 3, stopping the motor 801. At this point, the sampling shovel 1 stops, and the material scooped up by the stopped sampling shovel 1 is deposited into the receiving channel 11 under inertia.

[0050] Preferably, in this embodiment, one end of the waste material channel 5 is connected to the divider of the receiving channel 11, and the other end of the waste material channel 5 extends to the material conveyor belt 10 to transport the divided waste material to the material conveyor belt 10; a collection bucket 9 is connected below the collection channel 7.

[0051] Among them, the diameters of the aforementioned waste channel 5 and collection channel 7 are greater than 1.5 times the maximum particle size of the sample taken.

[0052] The diameter of the internal divider of the aforementioned receiving channel 11 is not less than 1.5 times the maximum particle size of the sample taken.

[0053] To avoid wasting material by spilling, an arc-shaped material baffle 12 is provided between the material receiving channel 11 and the material conveyor belt 10 in this embodiment. The material that the sampling shovel 1 spills is guided to the material conveyor belt 10 through the arc-shaped material baffle 12.

[0054] As an extended implementation method, the sampling shovel 1, waste channel 5, sampling shovel shaft 6, collection channel 7, divider, receiving channel 11 and arc-shaped material baffle 12 in this embodiment are all made of wear-resistant steel plate or wear-resistant steel pipe, and are equipped with an external protective structure to wrap the internal components.

[0055] The design requirements of the sampling shovel 1 in this embodiment should take into account the material thickness during belt operation, ensuring that the entire thickness cross-section can be sampled. At the same time, the length design of the sampling shovel 1 should take into account the curvature of the belt during operation, ensuring that the material at the bottom of the belt can be sampled as much as possible during automatic sampling. Secondly, since an arc-shaped material baffle 12 is designed, the length design of the sampling shovel 1 should avoid touching the arc-shaped material baffle 12.

[0056] In the above technical solution, the device provided by this utility model, which integrates automatic sampling, reduction, sample collection, and waste disposal, has the following beneficial effects:

[0057] The device of this invention operates stably, increases the representativeness of samples over a certain period of time, reduces the labor intensity of employees, and reduces the risk of unsafe operation.

[0058] The device of this invention automates sampling, reduction, collection and disposal, avoiding the safety risks of manual sampling. Furthermore, centralized control through control components reduces the labor intensity of personnel, and multiple samplings within the same time period increase the representativeness of the coke before and after calcination.

[0059] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
