Description

Technical Field

[0001] This utility model relates to the field of slag removal equipment technology, and in particular to a rocker arm slag removal device. Background Technology

[0002] Smelting furnaces require regular slag removal. Existing slag removal devices require multiple action groups to coordinate when performing complex slag removal actions, resulting in high investment costs for the control system. In contrast, with a single horizontal scraping action, as slag accumulates during the scraping process, some slag tends to overflow from the sides of the scraping rake, making it difficult to ensure thorough slag removal. Repeated scraping from the inside out takes a long time, leading to excessively long furnace door opening times and increased energy consumption. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a rocker arm slag removal device that can alternate between horizontal slag removal and swing slag removal, thereby achieving full removal of floating slag.

[0004] Technical solution: To achieve the above objectives, the present invention provides a rocker arm slag removal device, comprising a slag removal arm, an extension rod telescopically mounted at the front end of the slag removal arm, and a slag removal shovel fixedly mounted at the front end of the extension rod; the slag removal arm is connected to the upper part of the chassis via a linkage mechanism, the linkage mechanism being able to raise and lower the slag removal arm to lift it off the chassis or place it on the chassis, and the linkage mechanism being able to drive the slag removal arm to swing back and forth, so that the slag removal shovel can swing back and forth to scrape across a short distance of liquid surface.

[0005] Furthermore, the linkage mechanism includes a first link, the front end of the first link is hinged to the lower part of the front end of the slag removal arm, the rear end of the first link is hinged to the upper part of the longitudinal support member, and the longitudinal support member is fixedly installed on the chassis; the front end of the first link is connected to the first drive member, so that the front end of the first link can swing up and down.

[0006] Furthermore, the first driving component is a telescopic cylinder, one end of which is hinged to the upper part of the chassis, and the other end is hinged to the front end of the first connecting rod.

[0007] Furthermore, the linkage mechanism also includes a swing drive mechanism, which can generate a pulling or pushing force on the upper part of the slag-removing arm, causing the slag-removing arm to swing back and forth around its hinge axis with the first connecting rod.

[0008] Furthermore, the swing drive mechanism includes a second link, the front end of which is hinged to the upper part of the front end of the slag-removing arm, the rear end of which is hinged to the upper part of the rocker arm, the lower part of the rocker arm is hinged to the upper part of the chassis, and the rocker arm is connected to the second drive member, so that the upper end of the rocker arm can swing back and forth.

[0009] Furthermore, the second driving component is a telescopic cylinder, one end of which is hinged to the upper part of the chassis, and the other end of which is hinged to the upper part of the rocker arm.

[0010] Furthermore, the first link and the second link are parallel to each other.

[0011] Furthermore, the hinge point between the second connecting rod and the slag-removing arm is located behind the hinge point between the first connecting rod and the slag-removing arm.

[0012] Beneficial effects: The rocker arm slag removal device of this utility model can intermittently interweave swinging scraping actions during the slag removal action of moving from the inside to the outside. Both the moving slag removal and the swinging scraping are driven by a single drive component. Complex slag removal actions are achieved through a simple drive method. By performing multiple swinging scraping actions on the liquid surface swept by the slag removal shovel, the remaining slag on the liquid surface is scraped and piled up and merged with the slag piled up by the moving slag removal. The moving scraping and swinging scraping are alternately executed multiple times on the scraping path from the inside to the outside, which can effectively improve the slag removal rate and slag removal efficiency. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of one embodiment of the slag removal device of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As attached Figure 1 The aforementioned rocker arm slag removal device includes a slag removal arm 1, an extension rod 2 telescopically mounted at the front end of the slag removal arm 1, and a slag removal shovel 3 fixedly mounted at the front end of the extension rod 2; the slag removal arm 1 and the extension rod 2 form a telescopic arm structure, which can drive the slag removal shovel 3 to perform a translational slag removal action.

[0016] The slag-removing arm 1 is connected to the upper part of the chassis 4 through a linkage mechanism. The upper part of the chassis 4 can be configured as a sliding platform that can slide back and forth. The slag-removing shovel can be driven to perform horizontal slag-removing action by sliding the sliding platform back and forth. The telescopic arm structure can be used to adjust the depth of the slag-removing shovel into the furnace cavity.

[0017] The linkage mechanism can raise and lower the slag-removing arm 1 so that it is lifted off the chassis 4 or placed on the chassis 4. When performing slag removal operations, the slag-removing arm is raised to give it enough room to move, so as to achieve more flexible and complex slag removal operations. When the slag-removing arm is idle, it is placed on the chassis, and the chassis bears the weight of the slag-removing arm to prevent the linkage mechanism from deforming due to long-term load.

[0018] Furthermore, the linkage mechanism can drive the slag-scraping arm 1 to swing back and forth, allowing the slag-scraping shovel 3 to swing back and forth across a short distance of the liquid surface. With the extension rod 2's extension length remaining constant, by controlling the slag-scraping arm 1 to swing back and forth slightly, the end of the extension rod 2 can swing up and down slightly. Since the shovel surface of the slag-scraping shovel maintains a fixed angle with the extension rod, the shovel surface can swing and sweep across the liquid surface when the extension rod swings. During slag removal, the slag-scraping shovel is first moved horizontally across a certain area of ​​the liquid surface by the telescopic or sliding motion, scraping most of the scum outwards. Then, keeping the extension rod's extension length constant, the remaining scum on the liquid surface swept horizontally by the slag-scraping shovel is scraped and piled up through multiple swinging scraping motions, merging with the scum scraped and piled up by the horizontal scraping. By repeatedly alternating horizontal scraping and swinging scraping along the scraping path from the inside out, the scum removal rate and efficiency can be effectively improved.

[0019] Furthermore, after each swing of the scraper, the angle of the scraper arm can be readjusted to ensure that the scraper maintains a good positional relationship with the liquid surface during subsequent horizontal scraping, and will not be lifted off the metal liquid surface or inserted too deeply into the liquid surface, thus ensuring the scraping effect of the horizontal scraper.

[0020] Among them, the chassis 4 can also be an omnidirectional movable chassis, which can freely adjust the orientation of the slag scraper and the position of the entire device relative to the furnace opening.

[0021] Example: The linkage mechanism includes a first connecting rod 5. The front end of the first connecting rod 5 is hinged to the lower part of the front end of the slag-removing arm 1, and the rear end of the first connecting rod 5 is hinged to the upper part of the longitudinal support member 6. The longitudinal support member 6 is fixedly installed on the chassis 4. The front end of the first connecting rod 5 is connected to a first driving member 7, allowing the front end of the first connecting rod 5 to swing up and down. The first driving member 7 is a telescopic cylinder, with one end hinged to the upper part of the chassis 4 and the other end hinged to the front end of the first connecting rod 5. The longitudinal support member 6 positions the rear end of the first connecting rod 5 at a certain height above the base 4. When the slag-removing arm is idle, the first driving member retracts, causing the front end of the first connecting rod 5 to be lower than its rear end, thereby pulling the entire slag-removing arm down and placing it on the chassis. When slag removal is required, the first driving member 7 is extended, causing the first connecting rod 5 to swing to a horizontal position, thereby lifting the slag-removing arm away from the chassis 4. The first connecting rod 5, the longitudinal support member 6, and the first driving member 7 form a stable triangular support structure, ensuring the stability of the overall support for the slag-removing arm during the slag removal process.

[0022] The linkage mechanism also includes a swing drive mechanism, which can generate a pulling or pushing force on the upper part of the slag-removing arm 1, causing the slag-removing arm 1 to swing back and forth around its hinge axis with the first connecting rod 5.

[0023] The swing drive mechanism includes a second connecting rod 8. The front end of the second connecting rod 8 is hinged to the upper part of the front end of the slag-removing arm 1, and the rear end of the second connecting rod 8 is hinged to the upper part of the rocker arm 9. The lower part of the rocker arm 9 is hinged to the upper part of the chassis 4. The rocker arm 9 is connected to a second driving member 10, allowing the upper end of the rocker arm 9 to swing back and forth. The second driving member 10 is a telescopic cylinder, with one end hinged to the upper part of the chassis 4 and the other end hinged to the upper part of the rocker arm 9.

[0024] Preferred, such as Figure 1 As shown, the first connecting rod 5 and the second connecting rod 8 are parallel to each other. The hinge point between the second connecting rod 8 and the slag-removing arm 1 is located behind the hinge point between the first connecting rod 5 and the slag-removing arm 1. This ensures that the rocker arm 9 is always tilted backward at its upper end. The second driving member 10 is located behind the rocker arm 9. When the rocker arm is stationary, the second driving member 10, the upper part of the rocker arm 9, and the second connecting rod 8 can generate a pulling force on the upper part of the slag-removing arm. The first connecting rod 5, the longitudinal support member 6, and the first driving member 7 generate a supporting force on the lower part of the slag-removing arm, thus preventing the slag-removing arm from swaying and ensuring the stability of the extension rod 2's telescopic adjustment.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
