Description

Technical Field

[0001] The utility model relates to the technical field of pig casting machines, and particularly provides a slag scraping device and a pig casting machine. Background Art

[0002] At present, chain belt type pig casting machines are widely used in major enterprises. Under the head part of this kind of pig casting machine, a water flushing slag receiving plate is installed to prevent the slag and iron particulate matter splashing during pig casting from falling onto the rotating chain belt on the next layer. Although the water flushing slag receiving plate has a certain installation angle and the impact of water flow, it still cannot completely eliminate the phenomenon that the slag and iron splashing particulate matter with a certain speed adheres to the water flushing slag receiving plate. These particulate matters carry a certain amount of heat. When the adhesion amount is sufficient, the accumulated heat will cause the particulate matters to melt and condense into a whole block, and the main component is iron with a very large specific gravity. After each ladle of iron is cast, it is necessary to rely on manual labor to clean these accumulated iron and slag that are stuck together. When cleaning the accumulated iron and slag, it is necessary to stop flushing water, which increases the labor intensity of the cleaning work, and is also somewhat dangerous and takes a long time, affecting the continuity of the operation of the pig casting machine.

[0003] Correspondingly, the field needs a new slag scraping device and a pig casting machine to solve the above technical problems. Summary of the Utility Model

[0004] The utility model aims to solve the above technical problems, that is, to solve the problem of poor slag scraping effect of the existing slag scraping device of the pig casting machine.

[0005] In a first aspect, the utility model provides a slag scraping device, which is characterized in that it is used for scraping the slag receiving plate of the pig casting machine, and the slag scraping device includes:

[0006] The scraper assembly comprises a first scraper, a driving rod, a second scraper and a driven rod, a slag receiving surface being formed on the slag receiving plate, and the scraping surface of the first scraper contacts the slag receiving surface; the first end of the driving rod is rotatably connected to the first scraper through a first rotating connection member, the second end of the driving rod is rotatably arranged through a second rotating connection member, the second rotating connection member is fixed relative to the position of the slag receiving plate, so that the driving rod can drive the first scraper to swing between one end and the other end of the slag receiving surface around the second rotating connection member; the scraping surface of the second scraper contacts the slag receiving surface, and the second scraper is fixed parallel to the first scraper through a connecting member, so that the second scraper can maintain the movement trajectory of the first scraper on the slag receiving surface; the first end of the driven rod is rotatably connected to the second scraper through a third rotating connection member, the second end of the driven rod is rotatably arranged through a fourth rotating connection member, the driven rod is arranged parallel to the driving rod, the fourth rotating connection member is fixed relative to the position of the slag receiving plate, so that the driven rod can move around the fourth rotating connection member to maintain the movement trajectory of the driving rod;

[0007] A driving assembly, the driving assembly comprising a driving member and a transmission assembly, wherein the output end of the driving member is transmission-connected to the second end of the driving rod through the transmission assembly to provide power for the driving rod to rotate;

[0008] A water spray pipe, wherein the water spray end of the water spray pipe faces the slag connection surface and is used for spraying clean water onto the slag connection surface.

[0009] Based on the above configuration, the scraping device uses the first scraper and the second scraper in combination, and the driving rod and the driven rod cooperate, so that the first scraper can swing back and forth on the slag surface to scrape the slag, and the second scraper can assist in maintaining the movement trajectory of the first scraper to ensure the stability and uniformity of the scraping. At the same time, the setting of the water spray pipe can spray the slag surface with clean water, further improving the scraping effect and avoiding the accumulation of residue.

[0010] In the preferred technical solution of the above scraping device, the driving member is configured as a low-speed motor with a rotation speed of 10-60 r / min.

The first support rod is used to connect the middle parts of the first scraper and the second scraper; the second support rod is used to connect the first rotating connecting member and the third rotating connecting member.

[0019] Based on the above settings, the connecting member includes a first support rod and a second support rod. The first support rod is used to connect the middle parts of the two scrapers, and the second support rod connects each rotating connecting member, ensuring more uniform force transmission between the two scrapers and the driving rod. This structural design improves the stability of the scraper and makes the slag scraping movement more precise.

[0020] In the preferred technical solution of the above slag scraping device, the distances between the first scraper and the second scraper from the edge of the slag receiving plate are set to 5 - 50 mm.

[0021] Based on the above settings, the distances between the first scraper and the second scraper and the edge of the slag receiving plate are set to be 5 - 50 mm, ensuring that the scrapers can cover most of the slag receiving surface for slag scraping, but not be too close to the edge to avoid excessive impact and damage to the scrapers at the edge.

[0022] In the preferred technical solution of the above slag scraping device, the first rotating connector, the second rotating connector, the third rotating connector, and the fourth rotating connector are all set as shaft seats.

[0023] Based on the above settings, the rotating connectors all adopt the shaft seat structure, which can provide stable rotational support, ensure good flexibility and stability of the scrapers and rods during movement, reduce the friction between moving parts, and extend the service life of the device.

[0024] In the preferred technical solution of the above slag scraping device, the distance between the second rotating connector and the fourth rotating connector is 90 - 100 mm.

[0025] Based on the above settings, the distance between the second rotating connector and the fourth rotating connector is set to be 90 - 100 mm, ensuring a reasonable distance between the driving rod and the driven rod, which helps to improve the consistency of their movement trajectories and further enhance the stability and effect of the scraper movement.
