Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the preferred embodiments described herein are for purposes of illustration and understanding only and are not intended to limit the invention.
Embodiment a slag scraper for ladle mouth
As shown in fig. 1 to 4, the present embodiment includes a blade group, a connecting shaft 22, a frame 3, and a fixing portion 1.
Scraper set
The scraper group is of an integrated structure and is used for deslagging the steel ladle 4. The blade set includes an outer wall blade 33, an inner wall blade 31 and a lip blade 32, the lip blade 32 being located between the outer wall blade 33 and the inner wall blade 31. The inner wall scraper 31 is used for cleaning steel slag on the inner wall of the steel ladle 4, the cutting edge of the inner wall scraper 31 is in contact with the inner wall of the steel ladle 4, and the length of the inner wall scraper 31 is the same as the height of the steel ladle 4, so that the inner wall scraper 31 can extend to the inner bottom wall of the steel ladle 4. The edge of the lip scraper 32 contacts the upper surface of the ladle 4. The uncovered slope of outer wall scraper 33 sets up, makes outer wall scraper 33, inner wall scraper 31 and mouthful enclose into a right angle dovetail groove along scraper 32, easily makes ladle 4 insert the scraper group in, improves cleaning efficiency. The outer wall scraper 33, the lip scraper 32 and the inner wall scraper 31 are all single-sided blade structures, and the blades are located on the end surface of the scrapers contacting the ladle 4. The scraper set is fixedly arranged on the connecting plate 5.
Second, connecting shaft 22
The scraper group can be the multiunit, and every scraper group of every group is fixed to be located a connecting plate 5, and the connecting plate 5 of every scraper group of every group links to each other through connecting axle 22, is located every scraper group of every connecting plate 5 and is inner wall scraper 31, mouth along scraper 32 and outer wall scraper 33 to keeping away from connecting axle 22 one side in proper order. In the present embodiment, three scraper sets are provided, and the included angle between adjacent scraper sets in the circumferential direction of the connecting shaft 22 is 120 °.
Third, frame 3
One end of the connecting plate 5 of each scraper group, which is far away from the connecting shaft 22, is fixedly connected through the frame 3. The frame 3 is of a regular triangle structure, the triangle structure is stable, the manufacturing cost is reduced, the practicability and the economy are improved, and the supporting effect on the scraper group is good.
Fourth, fixed part 1
The fixing portion 1 provides support for the blade group. The fixing portion 1 is provided with a driving device 21 fixedly connected with the connecting shaft 22, the driving device 21 is a servo motor, the lower end of the fixing portion 1 is fixedly provided with a lifter 11 for changing the height of the fixing portion 1, in this embodiment, the driving device 21 can also be a rotary cylinder, and the lifter 11 can be a hydraulic press or a jack.
Fifth, work engineering
When the embodiment is used, the ladle 4 is hoisted by the crane, then the height of the ladle 4 is adjusted, and the axis of the ladle 4 is aligned with the axis of the connecting shaft 22. When the height of the ladle 4 is adjusted, the height of the fixing part 1 is changed through the lifter 11, and the speed and the accuracy of aligning the scraper group and the ladle opening of the ladle 4 are improved. After the scraper group and the ladle mouth of the ladle 4 are aligned, the travelling crane drives the ladle 4 to move, so that the inner wall scraper 31 is slowly inserted into the ladle 4 until the inner wall scraper 31 contacts the bottom wall of the ladle 4. After the ladle 4 is inserted into the right-angled trapezoidal groove surrounded by the scraper groups, the driving device 21 drives the connecting shaft 22 to rotate, and the scraper groups do circular motion around the axis of the ladle 4, so that the slag accumulated on the ladle 4 is cut and smashed.
