Description

Technical Field

[0001] This utility model belongs to the technical field of carbon block production equipment, specifically relating to a scraping device for green anode carbon blocks. Background Technology

[0002] In the manufacturing process of green anodes in the carbon industry, the molding workshop uses a vibration extrusion molding process to press the mixed paste into green anode carbon blocks. Due to the complex composition of the paste (containing pitch, calcined coke, etc.) and large differences in fluidity, coupled with limitations in mold precision and fluctuations in molding pressure, uneven burrs (also known as flash) are easily formed on the edges of the green anode carbon blocks. These burrs not only affect the appearance of the product, but also have multiple negative impacts on subsequent processes and the performance of the finished product.

[0003] The Chinese utility model patent with publication number CN215152203U, entitled "A Multifunctional Clamp for Molding Anode Carbon Blocks", includes a support frame, a solenoid valve group, an automatic edge scraping device, an infrared sensing height sensing device, an automatic oil spraying device, and a bulk material scraper. While capable of scraping the edges of raw anode carbon blocks, this device suffers from the following drawbacks: 1. Complex scraping process: The device is integrated with a molding machine, requiring spraying and paste leveling before scraping, resulting in low production efficiency. 2. Poor environmental adaptability: The infrared sensor is susceptible to environmental factors (dust, high temperature, flue gas, vibration), leading to decreased height measurement accuracy. 3. Complex system: The coordinated control of the solenoid valve group, infrared sensor, spraying mechanism, and bulk material scraper requires precise programming and debugging; infrared height measurement needs regular calibration to maintain its accuracy. 4. Poor response speed and accuracy: The start and stop of the solenoid valve group has a mechanical delay, which may cause lag in scraping action on high-speed production lines. 5. High cost and energy consumption: Infrared height measurement and the solenoid valve group are expensive, and the frequent operation of the solenoid valves results in high energy consumption. 6. High fault tolerance: Misjudgment of infrared height measurement may cause the scraper to damage the product and equipment. 7. High maintenance difficulty: The complex structure of the device makes maintenance and troubleshooting difficult, increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a scraping device for raw anode carbon blocks, which solves the technical problems of scraping delay or malfunction caused by low accuracy of infrared height measurement and delayed response of solenoid valve in traditional devices.

[0005] The technical solution adopted by this utility model is a scraping device for raw anode carbon blocks, including a steel frame with an n-shaped structure. The steel frame includes a horizontal section, and a first vertical section and a second vertical section are respectively fixedly connected to both ends of the horizontal section. Two stiffening plates are fixedly connected to the bottom of the horizontal section, and a rolling assembly is hinged to the bottom of each stiffening plate. A blade holder is installed at the bottom of the rolling assembly, and a scraper is installed on the blade holder by fasteners. It also includes a conveying device located between the bottom of the first vertical section and the bottom of the second vertical section.

[0006] The features of this utility model also include:

[0007] Limiting baffles are installed on the opposing sidewalls of the first and second vertical sections. The limiting baffles are arc-shaped plates, and the two arc-shaped plates are symmetrically arranged relative to the green anode carbon block to guide the green anode carbon block when it moves.

[0008] Support ribs are fixedly connected between the first vertical section and the second vertical section and the limiting baffle.

[0009] Both limit baffles are rotatably connected to limit rollers at their ends, which are used to guide the green anode carbon block as it moves.

[0010] The rolling assembly includes two opposing roller baffles, with the outer convex surface of the roller baffles facing the green anode carbon block. Multiple rollers are hinged between the middle of the two roller baffles, with the rotating surface of the rollers facing the green anode carbon block. The tops of the two roller baffles are rotatably connected to the reinforcing ribs via pins. The bottom sidewall of the roller baffles near the first and second vertical sections is integrally formed with the tool holder.

[0011] The limiting roller is axially connected with a pin, and a bushing is sleeved between the pin and the inner wall of the limiting roller. The two ends of the pin pass through the limiting baffle and are axially limited.

[0012] A counterweight rod is fixed between the two rolling groups. The counterweight rod has an n-shaped structure, and its two ends are fixed to the concave sides of the two roller baffles that are close to each other.

[0013] The conveying device uses a plate chain conveyor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By replacing complex sensors and electronic control systems with modular mechanical structures (such as articulated rolling blocks, arc-shaped limit baffles, and counterweight rod linkages), the scraping process is significantly simplified and adaptive adjustment of the green anode carbon block height is achieved. This solves the problems of scraping lag or malfunction caused by low infrared height measurement accuracy and solenoid valve response delay in traditional devices. The adoption of a fully mechanical guide and dynamic balance design (such as limit rollers, support rib reinforcement, and symmetrical layout of counterweight rods) improves scraping accuracy and uniformity while effectively resisting interference from harsh working conditions such as dust and vibration, reducing equipment maintenance costs and energy consumption. It is suitable for high-speed continuous production scenarios, balancing efficiency and reliability. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] like Figure 1-5 As shown, the scraping device for raw anode carbon blocks disclosed in this utility model includes a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, and a first vertical section and a second vertical section are respectively fixedly connected to both ends of the horizontal section. Two stiffening plates 2 are fixedly connected to the bottom of the horizontal section, and a rolling assembly is hinged to the bottom of each of the two stiffening plates 2. A knife holder 11 is installed at the bottom of the rolling assembly, and a scraper 10 is installed on the knife holder 11 by fasteners. It also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section.

[0025] In this embodiment, the steel frame 1 serves as the main support structure of the device, used to fix other components and ensure the overall stability and rigidity of the device. Rib plates 2 are installed on the steel frame to enhance its strength and stability, and to provide mounting support for the rolling assembly. Fasteners include fixing bolts 9. A scraper 10 is mounted on a blade holder 11 and is used to scrape the edges of the green anode carbon block 6. The angle of the scraper can be adjusted according to the size and shape of the green anode carbon block 6. The blade holder 11 is used to fix the scraper 10. A limiting baffle 13 is installed at an appropriate position on the device to limit the movement range of the green anode carbon block 6 and prevent excessive displacement of the green anode carbon block 6 during the scraping process. The green anode carbon block 6 is transported by a plate chain conveyor 14, which is existing technology and will not be described in detail here.

[0026] The horizontal and vertical sections of the steel frame 1 form an integral load-bearing structure, ensuring the stability of the device during scraping operations and preventing frame deformation caused by uneven weight distribution of the green anode carbon blocks 6. The articulated rolling assembly allows the scraper 10 to dynamically adjust with the height of the green anode carbon blocks 6, reducing manual intervention and making it suitable for the efficient processing of green anode carbon blocks 6 of different specifications.

[0027] Example 2

[0028] Based on Embodiment 1, the green anode carbon block scraping device disclosed in this utility model includes a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, and a first vertical section and a second vertical section are respectively fixedly connected to both ends of the horizontal section. Two stiffening plates 2 are fixedly connected to the bottom of the horizontal section, and a rolling assembly is hinged to the bottom of each stiffening plate 2. A blade holder 11 is installed at the bottom of the rolling assembly, and a scraper 10 is installed on the blade holder 11 by fasteners. It also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section. Limiting baffles 13 are installed on the opposing side walls of the first vertical section and the second vertical section. The limiting baffles 13 are arc-shaped plates, and the two arc-shaped plates are symmetrically arranged relative to the green anode carbon block to guide the green anode carbon block during its movement.

[0029] In this embodiment, symmetrical arc-shaped limiting baffles 13 are provided to correct the deviation of the green anode carbon block 6 during its movement through mechanical guidance, thus solving the positioning deviation problem caused by differences in paste flowability. The arc-shaped structure conforms to the surface of the green anode carbon block 6, reducing scraping resistance and preventing edge damage to the green anode carbon block 6 caused by sharp contact.

[0030] Example 3

[0031] Based on Embodiment 2, the green anode carbon block scraping device disclosed in this utility model includes a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, with a first vertical section and a second vertical section vertically fixed to both ends of the horizontal section. Two stiffening plates 2 are fixed to the bottom of the horizontal section, and rolling groups are hinged to the bottom of each stiffening plate 2. A knife holder 11 is installed at the bottom of the rolling group, and a scraper 10 is installed on the knife holder 11 by fasteners. The device also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section. Limiting baffles 13 are installed on the opposing side walls of the first and second vertical sections. The limiting baffles 13 are arc-shaped plates, and the two arc-shaped plates are symmetrically arranged relative to the green anode carbon block to guide the green anode carbon block during its movement. Supporting ribs 5 are fixed between the first and second vertical sections and the limiting baffles 13.

[0032] In this embodiment, a support rib 5 is added to connect the limiting baffle 13 and the vertical section of the steel frame 1. This is intended to enhance the impact resistance of the guide structure, prevent the limiting baffle 13 from deforming due to the impact of the green anode carbon block 6, and distribute the force through the triangular reinforcement principle. This extends the service life of the limiting baffle 13, reduces the guiding error caused by the deformation of the limiting baffle 13, and improves the long-term stability of the scraping operation.

[0033] Example 4

[0034] Based on Embodiment 2, the green anode carbon block scraping device disclosed in this utility model includes a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, with a first vertical section and a second vertical section vertically fixed to both ends of the horizontal section. Two stiffening plates 2 are fixed to the bottom of the horizontal section, and rolling groups are hinged to the bottom of each stiffening plate 2. A knife holder 11 is installed at the bottom of the rolling group, and a scraper 10 is installed on the knife holder 11 by fasteners. It also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section. Limiting baffles 13 are installed on the opposing side walls of the first and second vertical sections. The limiting baffles 13 are arc-shaped plates, and the two arc-shaped plates are symmetrically arranged relative to the green anode carbon block to guide the green anode carbon block during its movement. Limiting rollers 12 are rotatably connected to the ends of the two limiting baffles 13 to guide the green anode carbon block during its movement.

[0035] In this embodiment, a limiting roller 12 is added to the end of the limiting baffle 13 to reduce the frictional resistance between the green anode carbon block 6 and the limiting baffle 13, avoid scratches on the surface of the green anode carbon block 6, and reduce the travel resistance of the green anode carbon block 6 by rotating the limiting roller 12, thereby improving the conveying efficiency. It is especially suitable for high-speed production lines. The auxiliary guiding function can compensate for the size deviation of the green anode carbon block 6 and reduce the risk of the scraper 10 getting stuck.

[0036] Example 5

[0037] Based on Embodiment 1, the present invention discloses a scraping device for green anode carbon blocks, comprising a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, with a first vertical section and a second vertical section fixedly connected to both ends of the horizontal section. Two stiffening plates 2 are fixedly connected to the bottom of the horizontal section, and a rolling assembly is hinged to the bottom of each stiffening plate 2. A blade holder 11 is installed at the bottom of the rolling assembly, and a scraper 10 is installed on the blade holder 11 by fasteners. The device also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section. The rolling assembly includes two opposing roller baffles 8, with the outer convex surface of the roller baffles 8 facing the green anode carbon block. Multiple rollers 4 are hinged between the middle of the two roller baffles 8, with the rotating surface of the rollers 4 facing the green anode carbon block. The tops of the two roller baffles 8 are rotatably connected to the stiffening plates 2 by pins. The bottom sidewall of the roller baffles 8 near the first and second vertical sections is integrally formed with the blade holder 11.

[0038] Furthermore, a pin is axially inserted through the roller 4, and a bushing 3 is sleeved between the pin and the inner wall of the roller 4. Both ends of the pin pass through the limiting baffle 13 and are axially limited.

[0039] In this embodiment, roller baffles 8 are installed on both sides of roller 4 to prevent the green anode carbon block from shifting or falling off during the conveying process. The rolling assembly adopts a hinged structure between roller 4 and roller baffles 8, which aims to buffer the scraping pressure through dynamic contact and simplify the adjustment mechanism of the tool holder 11. The rotating surface of roller 4 makes flexible contact with the green anode carbon block 6, reducing the impact of scraping vibration on the stability of the device. The tool holder 11 and roller baffles 8 are integrally formed, reducing the complexity of mechanical linkage and facilitating maintenance and replacement. A bushing 3 is nested inside the limiting roller 12 to reduce the wear rate between the pin and roller 4 and extend the service life of the component. The bushing can be made of wear-resistant materials, such as nylon or copper alloy, to reduce direct metal-to-metal friction and reduce maintenance frequency. This ensures the smooth rotation of roller 4 and avoids the shifting of green anode carbon block 6 due to jamming.

[0040] Example 6

[0041] Based on Embodiment 5, the present invention discloses a scraping device for green anode carbon blocks, comprising a steel frame 1, which has an n-shaped structure. The steel frame 1 includes a horizontal section, with a first vertical section and a second vertical section fixedly connected to both ends of the horizontal section. Two stiffening plates 2 are fixedly connected to the bottom of the horizontal section, and a rolling assembly is hinged to the bottom of each stiffening plate 2. A blade holder 11 is installed at the bottom of the rolling assembly, and a scraper 10 is installed on the blade holder 11 by fasteners. The device also includes a plate chain conveyor 14 located between the bottom of the first vertical section and the bottom of the second vertical section. The rolling assembly includes two opposing roller baffles 8, with the outer convex surface of the roller baffles 8 facing the green anode carbon block. Multiple rollers 4 are hinged between the middle of the two roller baffles 8, with the rotating surface of the rollers 4 facing the green anode carbon block. The tops of the two roller baffles 8 are rotatably connected to the stiffening plates 2 by pins. The bottom sidewall of the roller baffles 8 near the first and second vertical sections is integrally formed with the blade holder 11. A counterweight rod 7 is fixedly connected between the two rolling groups. The counterweight rod 7 has an n-shaped structure, and its two ends are fixedly connected to the concave sides of the two roller baffles 8 that are close to each other.

[0042] In this embodiment, an n-shaped counterweight rod 7 is set to connect the rolling groups on both sides, which aims to counteract the unilateral pressure of the scraper 10 during operation through gravity balance, thereby improving the uniformity of scraping. The symmetrical layout of the counterweight rod 7 prevents the green anode carbon block 6 from tilting or falling off due to uneven force, which is especially suitable for processing large-sized green anode carbon blocks 6; the mechanical counterweight replaces the traditional hydraulic / pneumatic balancing system, reducing energy consumption and failure rate.

[0043] The working principle of this utility model is as follows:

[0044] When using this device, the green anode carbon block 6 is pulled into the area formed between the two limiting baffles 13 by the plate chain conveyor 14. The green anode carbon block 6 first contacts the roller 4, which swings to the height of the green anode carbon block 6 under the action of force. The roller 4 rolls smoothly on the top surface of the green anode carbon block 6. The scraper 10 is mounted on the blade holder 11 and scrapes the edge of the green anode carbon block 6 by the traction of the plate chain conveyor 14 and the action of the counterweight 7. The counterweight 7 and the limiting baffles 13 ensure the balance and stability of the device during the scraping process and prevent the green anode carbon block 6 from shifting or falling off.
