Description

Technical Field

[0001] This utility model relates to the field of anode carbon block sampling technology, specifically to an intelligent sampling system for prebaked anode carbon blocks. Background Technology

[0002] In the electrolytic production process, the prebaked anode plays a crucial role as the "heart" of the process. The quality of the prebaked anode directly affects the current efficiency and energy consumption of aluminum electrolysis. The anode has been roasted and possesses a stable geometric shape. To ensure the quality of the prebaked anode, samples must be selected from each batch of roasted blocks for testing. This testing is used to analyze important parameters such as resistivity, trace elements, compressive strength, and residual air reaction rate, ensuring the normal operation of aluminum electrolysis. Common sampling equipment only allows for anode transfer, sampling at a rate of 5%-10% each time. This requires two or more people working together, and only one sample can be taken at a time, taking one hour per sample. The sampling efficiency is extremely low. Furthermore, the high strength of the anode demands highly skilled sampling workers, resulting in high labor intensity and significant safety hazards during the sampling process. Existing technologies include methods for transporting anodes to sampling equipment using conveying devices. For example, Chinese Patent CN114624244B discloses a system and method for detecting internal quality defects in prebaked anodes using a multi-point deformation method, which utilizes a conveying device to transport the anodes, reducing the labor intensity of workers. However, the sampling methods in existing technologies are still not intelligent enough, and the uniformity of sampling locations for different samples still needs to be improved.

[0003] Therefore, there is a need to develop a safe, efficient, labor-saving, and structurally simple intelligent sampling system for prebaked anode carbon blocks. Utility Model Content

[0004] To address the problems of existing technologies, this invention proposes an intelligent sampling system for prebaked anode carbon blocks. The specific solution is as follows:

[0005] A prebaked anode carbon block intelligent sampling system includes a sampler, an infrared sensor, two parallel tracks, a horizontal moving device, and a control system. The prebaked anode carbon block is located between the two parallel tracks, which are concave tracks with an opening running through the middle of their horizontal plane. The infrared sensor is mounted on the sampler and has a through hole located directly below the infrared emission position of the sensor. The horizontal moving device includes a support platform and support legs fixed at the four corners of the support platform, with pulleys fixed to the bottom of the support legs. The prototype is fixed on a support platform, and an opening is provided at the support platform perpendicular to the sampling component of the sampler. The pulley slides in the track, and a horizontal brake plate is provided above the pulley. The brake plate is lower than the upper horizontal plane of the track and its width is greater than the opening that runs through the middle of the upper horizontal plane. The side of the pulley is fixed to the sprocket shaft. A drive motor is provided at both ends of the track. The sprocket of the drive motor is connected to the pulley sprocket via a chain. An electric braking device is provided on the pulley. The sampler, drive motor, electric braking device, infrared sensor and control system are electrically connected.

[0006] Furthermore, the sampling machine is an RD sampling machine.

[0007] Furthermore, the sampling machine includes a vertical motion sampling component and a hydraulic power system. The vertical motion sampling component includes a lifting platform, which is connected to the hydraulic power system. A sampling motor is fixed on the lifting platform, and a guide rod is fixed to the lower surface of the lifting platform. A rotating sampling drill bit passes through the guide rod and is connected to the sampling motor via the lifting platform. Infrared sensors are symmetrically arranged on both sides of the sampling motor. The lifting platform has a through hole located directly below the infrared emission position of the infrared sensor, and the infrared light from the infrared sensor can pass through the opening of the support platform.

[0008] Furthermore, the sprocket of the drive motor is connected to a pulley sprocket located on the side of the drive motor.

[0009] Furthermore, a control box is also provided, and the control system is located in the control box.

[0010] This utility model's intelligent sampling system for prebaked anode carbon blocks achieves rapid sampling by designing a track and a mobile device that carries the sampling equipment. In addition, infrared positioning ensures consistency in sampling different carbon blocks. Furthermore, the system interlocks and controls the mobile power source and the sampling machine to achieve intelligent and automated sampling, solving problems such as significant safety hazards, cumbersome procedures, high labor intensity, and low efficiency in sampling.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0016] In one embodiment, a prebaked anode carbon block intelligent sampling system includes an RD sampler 2, an infrared sensor 9, two parallel tracks 3, a horizontal moving device, and a control system. The prebaked anode carbon block 1 is located between the two parallel tracks 3. The tracks 3 are concave tracks, and the left and right sidewalls of the concave tracks are higher than the height of the pulleys 6. The width between the left and right sidewalls of the concave tracks is greater than the width of the pulleys 6, ensuring that the sliding of the horizontal moving device is not easily derailed and limiting its left and right sides perpendicular to the direction of movement. The horizontal surface of the concave track has an opening that runs through the front and back. The design of the concave track can also prevent carbon slag and dust from entering the track, affecting the stability and accuracy of the movement.

[0017] The sampling machine 2 includes a vertical motion sampling component and a hydraulic power system. The vertical motion sampling component includes a lifting platform 22, which is connected to the hydraulic power system. A sampling motor 21 is fixed on the lifting platform 22. A guide rod 23 is fixed to the lower surface of the lifting platform 22. A rotating sampling drill bit 24 passes through the guide rod 23 and is connected to the lifting platform 22 and the sampling motor 21. In the hydraulic power system, the hydraulic station transmits pressure to the oil cylinder. The extension and retraction of the oil cylinder piston rod drives the vertical movement of the telescopic rod. The vertical movement of the telescopic rod controls the lifting platform 22 and the rotating sampling drill bit 24 to press down and retract.

[0018] The infrared sensors 9 are symmetrically arranged on both sides of the sampling motor 21. They can be on the front and back sides (the position and direction of movement are front and back) or on the left and right sides. In this embodiment, they are arranged on the front and back sides. The lifting platform 22 has a through hole, which is located directly below the infrared emission position of the infrared sensor 9.

[0019] The horizontal moving device includes a support platform 4 and support legs 5 fixed at the four corners of the support platform 4. Pulleys 6 are fixed to the bottom of the support legs 5. The sampler 1 is fixed to the support platform 4, and an opening 7 is provided at the vertical position of the sampling component of the sampler 2 corresponding to the support platform 4. Infrared light from the infrared sensor 9 can pass through the opening 7 of the support platform 4. The pulleys 6 slide in the track 3. A horizontal brake plate 8 is provided above the pulleys 6. The brake plate 8 is lower than the upper horizontal plane of the track 3, and its width is greater than the opening running through the middle of the upper horizontal plane. During sampling, the sampler will generate an upward force. The upper side arms of the concave track (the left and right sides of the upper horizontal plane)... The two side arms (considered as two side arms) are tightly fitted with the pulley brake plate 8 of the horizontal moving device to prevent the drill bit from shifting and getting stuck during sampling, and to achieve vertical limiting. The side of the pulley 6 is fixed to the sprocket shaft. The two ends of the track are equipped with drive motors. The sprockets of the drive motors are respectively connected to the pulley sprockets on the side closest to the drive motor. The pulley 6 is equipped with an electric braking device, which uses AC power to drive the chain through the rotation of the drive motor sprocket. The chain transmits power to the four pulleys of the horizontal moving device, realizing the synchronous movement of the four wheels and stopping the machine through the electric braking device, thus achieving precise positioning of the sampling location.

[0020] The sampler 2, drive motor, electric brake device, and infrared sensor 9 are all electrically connected to the control system. A control box 10 is provided, and the control system is located in the control box. The outer panel of the control box is equipped with start and stop buttons and is connected to the drive motor and infrared sensor.

[0021] The process of using this system includes the following:

[0022] S1: Place the pre-baked anode carbon block 1 to the sampling area via an anode clamp crane or chain conveyor.

[0023] S2: The sampling area is located between two concave tracks, arranged longitudinally, and multiple samples can be placed at once.

[0024] S3: Activate the power supply by pressing the start button on the outer panel of the control box. Start the drive motor, and the horizontal moving device enters from the end of the track. The brake plate on the pulley slides into the concave track and moves along the track.

[0025] S4: The two infrared sensors on the horizontal moving device emit infrared rays and simultaneously detect the prebaked anode carbon block, feeding back to the control system. The control system controls the drive motor to stop and the electric braking device to stop, ensuring that the sampling position of each anode is consistent, thereby achieving uniform and accurate sampling of each anode and controlling the sampling machine to work for sampling.

[0026] S5: After the sampler completes one sampling, it feeds back to the control system to restart the drive motor and unlock the electric brake device. The horizontal moving device continues to move along the track, repeating step S4.

[0027] S6: After completing the sampling in the sampling area, press the stop button on the outer panel of the control box to cut off the power and complete the sampling work. When using this system, the sampling time is shortened to 5 minutes per block.

[0028] The foregoing description describes some exemplary embodiments of this utility model. It is understood that the above embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
