[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0029] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0030] The utility model provides a slag removal device for producing ductile iron pipes. Figures 1 to 4 As shown, it includes a first bracket 1 and a second bracket 2. The first bracket 1 is slidably matched with a sliding block 11, and the sliding block 11 is slidably matched with a support column 12. The support column 12 rises and falls in the vertical direction of the sliding block 11. A rotatable slag cleaning rake 3 is installed on the top of the support column 12. The support column 12 is fixedly connected with a first fulcrum structure 4, and the first fulcrum structure 4 is rotatably connected with an operating rod 5. A second fulcrum structure 6 is arranged on the second bracket 2, and the second fulcrum structure 6 is rotatably connected with the operating rod 5, so that the operating rod 5 can drive the slag cleaning rake 3 to rise and fall, move horizontally, and rotate.

[0031] In this embodiment, by operating the operating rod 5, the support column 12 and the slag cleaning rake 3 can be driven to rise or fall in the vertical direction by utilizing the rotatable connection between the first fulcrum structure 4 and the second fulcrum structure 6. This lifting mechanism helps the slag cleaning rake 3 to adapt to the slag cleaning needs at different heights. The sliding of the sliding block 11 on the first bracket 1, combined with the vertical lifting of the support column 12, jointly realizes the horizontal movement of the slag cleaning rake 3, so that the slag cleaning rake 3 can cover a wider cleaning area. In this embodiment, the first fulcrum structure 4 and the second fulcrum structure 6 serve as the connection points between the operating rod 5 and other parts of the device, which not only realizes the transmission of force, but also ensures the stability and flexibility of the operating rod 5 during the rotation process.

[0032] In this embodiment, the first fulcrum structure 4 includes a mounting seat 41 and a spherical connector 42 rotatably matched with the mounting seat 41. The mounting seat 41 is fixedly connected to the bottom end surface of the support column 12. A mounting groove for installing the spherical connector 42 is provided on the mounting seat 41. The opening of the mounting groove faces the side of the operating rod 5, and the spherical connector 42 is fixedly connected to the operating rod 5.

[0033] In this embodiment, when the position of the slag cleaning rake 3 needs to be adjusted, the operator can drive the spherical connector 42 to rotate in the mounting groove by controlling the operating lever 5. Since the spherical connector 42 and the mounting seat 41 are in a rotatable matching relationship, the operating lever 5 can drive the support column 12 and the slag cleaning rake 3 to move and adjust in multiple directions, and enable the device to more flexibly cope with various complex working conditions and slag distribution conditions during the cleaning process. At the same time, due to the close fit and stable connection between the spherical connector 42 and the mounting seat 41, the stability and reliability of the entire device during operation are ensured.

[0034] In this embodiment, the second fulcrum structure 6 includes a rotating seat 61 rotatably connected to the second support frame, a mounting frame 62 is provided on the rotating seat 61, a support seat 63 is rotatably connected to the mounting frame 62, and the operating rod 5 is fixedly connected to the support seat 63. In this embodiment, the rotatable connection between the rotating seat 61 and the second support frame is realized through a bearing, and the rotation of the support seat 63 on the mounting frame 62 is realized by a connecting pin passing through the support seat 63.

[0035] During the operation of the slag removal device, when the position of the slag removal rake 3 needs to be adjusted, the operator can drive the rotating seat 61 to rotate on the mounting frame 62 by controlling the operating rod 5. Since the rotating seat 61 and the second support frame are rotatably connected, this rotation will be further transmitted to the operating rod 5 and the slag removal rake 3, so that the slag removal rake 3 can be moved and adjusted in the horizontal direction; at the same time, the second fulcrum structure 6 adopts the lever principle, combined with the action of the first fulcrum structure 4 (the lifting and lowering movement of the support column 12 on the sliding block 11), the operating rod 5 can also drive the slag removal rake 3 to lift and lower in the vertical direction. Through the joint action of the first fulcrum structure 4 and the second fulcrum structure 6, the device allows the slag removal rake 3 to move flexibly in three-dimensional space to cover a wider cleaning area and improve cleaning efficiency.

[0036] In other embodiments, the external force driving the operating rod 5 may be manual drive or a power component such as a cylinder, a hydraulic cylinder, or a motor mechanical drive.

[0037] In this embodiment, the central axis of the rotating seat 61 is parallel to or coincides with the central axis of the second bracket 2, and the axis of the support seat 63 is perpendicular to the central axis of the rotating seat 61. In this device, the second fulcrum structure 6 is the fulcrum of the lever. In the second fulcrum structure 6, the application of the lever principle enables the rotating seat 61 to rotate under the action of power or resistance. At the same time, the relative position relationship between the rotating seat 61 and the second bracket 2 and the support seat 63 also ensures the smoothness of rotation and the stability of the structure. In this embodiment, by adjusting the length of the power arm and the resistance arm, different labor-saving effects or changes in the speed and force of rotation can be achieved. In this embodiment, the central axis of the rotating seat 61 coincides with the central axis of the second bracket 2. In other embodiments, the central axis of the rotating seat 61 can also be parallel to the central axis of the second bracket 2, which is used in situations where a certain distance needs to be maintained or direct contact needs to be avoided.

[0038] In this embodiment, a sliding groove 13 is provided on the first bracket 1, and the sliding block 11 slides in cooperation with the sliding groove 13. An anti-slip portion 111 is provided on the sliding block 11, and the anti-slip portion 111 and the first bracket 1 abut against each other. In this embodiment, anti-slip portions 111 are provided at both the upper and lower ends of the sliding block 11, and the anti-slip portion 111 maintains close contact and abutment with the first bracket 1, which can effectively prevent the sliding block 11 from falling off the first bracket 1 and increase the stability of the sliding block 11 during the sliding process.

[0039] In this embodiment, the sliding block 11 is provided with a through hole 112, and the support column 12 passes through the through hole 112. The support column 12 rises and falls along the through hole 112. The through hole 112 provides a through path for the support column 12, so that the support column 12 can stably pass through the sliding block 11, ensuring that it rises and falls along the predetermined direction.

[0040] In this embodiment, a limiting groove 121 is provided on one end face of the support column 12 facing the slag cleaning rake 3. The slag cleaning rake 3 is engaged with the support column 12 through the limiting groove 121 to ensure the stability of the slag cleaning rake 3 on the support column 12, thereby ensuring the stability of the slag cleaning rake 3 during movement and lifting. In addition, the setting of the limiting groove 121 facilitates the disassembly and replacement of the slag cleaning rake 3, and is more practical. In this embodiment, the slag cleaning rake 3 can rotate in the limiting groove 121, and the rotation drive mode can be a variety of control modes such as manual or motor drive.

[0041] In this embodiment, the material of the slag cleaning rake 3 that contacts the molten iron is Cr25 high-chromium cast iron, which ensures the slag cleaning efficiency and service life of the device. In other embodiments, the material of the slag cleaning rake 3 that contacts the molten iron can also be set to other high-temperature resistant metal materials such as nickel-based alloys and tungsten alloys. When selecting the material, it is necessary to comprehensively consider multiple factors, including the temperature and composition of the molten iron, slag cleaning efficiency requirements, equipment cost, and maintenance difficulty.

[0042] In this embodiment, the slag cleaning rake 3 hangs the waste slag in the molten iron ladle 7 to one side of the molten iron ladle 7 through horizontal movement, and then drives the slag cleaning rake 3 to rise, and at the same time operates the slag cleaning rake 3 to rotate, so as to realize the cleaning of the waste slag from the molten iron ladle 7.

[0043] The utility model provides a slag removal device for ductile iron pipe production. The device can realize the lifting and horizontal movement of the slag removal rake 3 by simply operating the operating rod 5. The slag removal rake can be rotated independently to realize the removal of waste slag from the molten iron ladle, which reduces the difficulty of operation and can effectively improve the work efficiency. In addition, the device can make the slag removal rake 3 more stable in the horizontal and vertical directions through the coordinated use of the sliding block 11 and the supporting column 12, and can effectively improve the flexibility of the cleaning operation.
