Description

Technical Field

[0001] This utility model relates to the field of molten steel sampling technology, and more specifically, to a molten steel sampling mechanism. Background Technology

[0002] In the steelmaking process, multiple sampling operations are required to ensure the quality of molten steel. In existing technologies, such as the literature with application number CN202210726571.8, sampling can be achieved by connecting the sampling rod and the sampler with a clamp. Although sampling can be completed, it has the following defects: during sampling, it cannot effectively clean impurities on the surface of the molten steel, resulting in a large number of impurities in the sample and affecting the sampling results. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a molten steel sampling mechanism to solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The molten steel sampling mechanism includes a frame, a ladle, a liquid surface, and a sampling spoon, and also includes; The sampling tray has a round hole in the center for the sampling spoon to pass through. The slidable plate is mounted on the sampling plate. The rotation of the sampling plate generates centrifugal force, which causes the slid to move centrifugally and move the liquid surface.

[0005] Furthermore, it includes a main telescopic cylinder mounted on the frame, a rotating motor mounted on the telescopic end of the main telescopic cylinder, a connecting frame mounted on the rotating end of the rotating motor, a sampling disc mounted on the lower end of the connecting frame, a secondary telescopic cylinder mounted on the side wall of the connecting frame, a sampling spoon mounted on the secondary telescopic cylinder, and a quick-release connection between the sampling spoon and the secondary telescopic cylinder.

[0006] Furthermore, the sampling plate has a notch that extends to a round hole. A sliding block is installed on the notch and is slidably connected to the notch. A connecting rod is installed at the lower end of the sliding block, and a lever is installed at the lower end of the connecting rod. A compression spring is installed between the sliding block and the sampling plate.

[0007] Furthermore, the top view of the lever plate is arc-shaped, and there are complementary openings on both sides of the lever plate. There are three lever plates, and adjacent lever plates are interlocked through the complementary openings. There is a diagonal bar at the lower end of the lever plate.

[0008] The beneficial effects of this utility model are: by setting the dial plate, the liquid surface can be cleaned instantly before sampling; the rotation of the sampling disc generates centrifugal force, causing the dial plate to move centrifugally and move the liquid surface; the dial plate can be automatically reset by the action of the compression spring. The interlocking of complementary ports can improve the stability of the moving plate and also achieve the effect of cleaning slag. By setting the diagonal bar, impurities at the sampling center position can be moved as much as possible. Attached Figure Description

[0010] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0011] This application provides a steel sampling mechanism; please refer to [reference needed]. Figures 1-3 It includes a frame 1, a steel ladle 2, a liquid surface 3, and a sampling spoon 4, and also includes; Sampling plate 5, with a round hole 6 in the center of sampling plate 5, through which sampling spoon 4 passes; The lever 7 is slidably mounted on the sampling plate 5. The rotation of the sampling plate 5 generates centrifugal force, causing the lever 7 to make centrifugal motion, and the lever 7 moves the liquid surface 3.

[0012] In practical applications, when taking samples, the sampling disk 5 is moved directly above the ladle 2, and then the sampling disk 5 is moved to a position close to the liquid surface 3. Then the sampling disk 5 is rotated and moved downwards. At this time, the shovel 7 moves centrifugally under the action of centrifugal force. The shovel 7 moves the liquid surface 3, causing the impurities on the liquid surface 3 to be removed. Then, the sampling spoon 4 is moved down to take a sample from the liquid surface 3 where there are no impurities.

[0013] Reference Figure 1 , Figure 2 , Figure 3 It includes a main telescopic cylinder 8 installed on the frame 1, a rotating motor 9 installed at the telescopic end of the main telescopic cylinder 8, a connecting frame 10 installed at the rotating end of the rotating motor 9, a sampling plate 5 installed at the lower end of the connecting frame 10, a secondary telescopic cylinder 11 installed on the side wall of the connecting frame 10, a sampling spoon 4 installed on the secondary telescopic cylinder 11, and a quick-release connection between the sampling spoon 4 and the secondary telescopic cylinder 11.

[0014] In practical applications, the extension of the main telescopic cylinder 8 can drive the connecting frame 10 and the sampling plate 5 to move downward as a whole, and the extension of the auxiliary telescopic cylinder 11 can drive the sampling spoon 4 to pass through the round hole 6, which facilitates the sampling operation of the sampling spoon 4. The quick-release connection between the sampling spoon 4 and the auxiliary telescopic cylinder 11 makes it easy for the staff to remove the sampling spoon 4. The quick-release connection method is existing technology, so it will not be described in detail.

[0015] Reference Figure 1 , Figure 2 , Figure 3 The sampling plate 5 has a notch 51 extending to the round hole 6. A sliding block 52 is installed on the notch 51 and is slidably connected to the notch 51. A connecting rod 53 is installed at the lower end of the sliding block 52. A lever 7 is installed at the lower end of the connecting rod 53. A compression spring 54 is installed between the sliding block 52 and the sampling plate 5.

[0016] In practical applications, when the sampling disk 5 is stationary under the action of the compression spring 54, the sliding block 52 and the lever 7 are close to each other. When the sampling disk 5 rotates, the centrifugal force is greater than the elastic force of the compression spring 54, causing the lever 7 to move away from each other. The reset can be achieved by the elastic force of the compression spring 54.

[0017] Reference Figure 1 , Figure 2 , Figure 3 The top view of the lever 7 is arc-shaped. There are complementary openings 71 on both sides of the lever 7. There are three levers 7. Adjacent levers 7 are interlocked through the complementary openings 71. The lower end of the lever 7 is provided with a diagonal bar 72.

[0018] In practical applications, the interlocking of complementary ports 71 can improve the stability of the movement of the dial plate 7 and also achieve the effect of cleaning slag. By setting the inclined rod 72, the impurities at the sampling center position can be moved as much as possible.
