Description

Technical Field

[0001] This utility model relates to the field of protective slag processing technology, specifically a vibrating screen machine for processing protective slag with a striking structure. Background Technology

[0002] Mold flux is an important auxiliary material in continuous casting production. Along with the development of continuous casting technology in China's steelmaking industry, mold flux technology has also made continuous progress. The functions of mold flux include: preventing re-oxidation of molten steel; reducing heat loss from the molten steel surface and preventing premature solidification and crust formation; dissolving and absorbing inclusions on the molten steel surface; controlling the heat transfer rate of the billet and reducing thermal stress caused by the temperature gradient in the thickness direction of the solidified layer; and acting as a lubricant between the mold and the billet shell.

[0003] According to a vibrating screen (announcement number: CN111999222B) published in the above application, when screening materials, only screening is performed. However, the protective slag raw material will clump together, which the vibrating screen cannot effectively deal with, resulting in blockage and shutdown, affecting work efficiency. In order to address this problem, we propose a vibrating screen for processing protective slag with a knocking structure. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screen for processing protective slag with a striking structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for processing protective slag with a striking structure, comprising a base, a collection frame placed on the surface of the base, the surface of the base being fixedly connected to the bottom of a support plate, a body being fixedly installed on the top of the support plate, a connecting frame being fixedly installed on the surface of the body, a screen plate being fixedly installed on the inner wall of the body, a motor being fixedly installed on the surface of the connecting frame, and a control component for striking the screen plate being provided inside the body. The control component includes: a circular plate, which is rotatably connected to the inner wall of the body, the surface of the circular plate being hinged to a striking rod, the surface of the striking rod being fixedly connected to one side of a torsion spring, and the other side of the torsion spring being fixedly installed on the surface of the circular plate; and a movable plate, the surface of which is fixedly equipped with a conical spike, thereby crushing the clumps of protective slag that fall onto the surface of the screen plate, avoiding blockages, machine stoppages, and reduced work efficiency.

[0006] Preferably, the control assembly further includes a striking element, which includes a reciprocating lead screw that passes through the machine body and is rotatably connected to the machine body. The reciprocating lead screw is fixedly connected to the surface of the circular plate. When the reciprocating lead screw rotates on the surface of the machine body, the circular plate fixed to the surface of the reciprocating lead screw can rotate synchronously within the machine body.

[0007] Preferably, the surface of the reciprocating lead screw is fixedly connected to the output shaft of the motor, the reciprocating lead screw passes through the moving ring and is threadedly connected to the moving ring, and when the reciprocating lead screw rotates, the moving ring can move laterally on the surface of the reciprocating lead screw.

[0008] Preferably, the movable ring is penetrated by a support rod and slidably connected to the support rod. The support rod is fixedly installed on the inner wall of the connecting frame. The support rod ensures the stability of the movable ring during movement.

[0009] Preferably, the surface of the moving ring is hinged to one end of the push rod, and the other end of the push rod is hinged to the surface of the moving block. When the moving ring moves, the push rod can be folded to push the moving block to move longitudinally.

[0010] Preferably, the movable block passes through the machine body and is slidably connected to the machine body. The inner wall of the machine body is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the surface of the movable block. The surface of the movable block is fixedly connected to the surface of the movable plate. When the movable block is subjected to a pushing force, it can slide within the machine body under the support of the spring.

[0011] Preferably, a support block is fixedly installed on the inner wall of the movable block, the surface of the support block is hinged to the movable plate, and a knocking block is fixedly installed on the surface of the movable plate. When the movable plate is subjected to force, it can be folded on the surface of the support block, and the knocking block can be used to knock on the surface of the movable plate.

[0012] Compared with the prior art, this utility model provides a vibrating screen for processing protective slag with a striking structure, which has the following beneficial effects:

[0013] 1. This vibrating screen for processing protective slag with a striking structure, through the installation of a control component, allows the output shaft of the motor to drive the reciprocating screw and the circular plate to rotate within the machine body. The striking rods hinged to the surface of the circular plate continuously strike the surface of the screen plate. Simultaneously, as the reciprocating screw rotates, the moving ring can move laterally along the surface of the support rod. When the moving ring moves, the push rod hinged to its surface can fold, pushing the moving block to move longitudinally within the machine body. As the moving block moves, the moving plate fixed to its surface can synchronously drive the cone spikes to move longitudinally, thereby crushing the clumps of protective slag that fall onto the screen plate surface, preventing blockages, machine downtime, and reduced work efficiency.

[0014] 2. This vibrating screen for processing protective slag with a striking structure is equipped with striking elements. When the moving block moves downward, the inner wall of the machine body will no longer abut against one end of the movable plate. The movable plate can then tend to be balanced on the surface of the support block. After being balanced, the movable plate can strike the surface of the moving plate with the striking elements, so that the protective slag material remaining on the cone surface can fall off under force, which is convenient for subsequent screening.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a vibrating screen for processing protective slag with a striking structure, including a base 1, a collection frame 2 placed on the surface of the base 1, the surface of the base 1 fixedly connected to the bottom of a support plate 3, a body 4 fixedly installed on the top of the support plate 3, a connecting frame 5 fixedly installed on the surface of the body 4, a screen plate 6 fixedly installed on the inner wall of the body 4, a motor 7 fixedly installed on the surface of the connecting frame 5, and a control component 8 for striking the screen plate 6 provided inside the body 4. The control component 8 includes: a circular plate 81, the circular plate 81 being rotatably connected to the inner wall of the body 4, the surface of the circular plate 81 being hinged to a striking rod 82, and the surface of the striking rod 82 being fixedly connected to one side of a torsion spring 83. The torsion spring 83 is fixedly mounted on the surface of the circular plate 81 on the other side. The conical spike 85 is fixedly mounted on the surface of the moving plate 84. When the reciprocating screw 861 rotates, the moving ring 862 can move laterally along the surface of the support rod 863. When the moving ring 862 moves, the push rod 864 hinged to the surface of the moving ring 862 can be folded, pushing the moving block 865 to move longitudinally within the machine body 4. When the moving block 865 moves, the moving plate 84 fixed to the surface of the moving block 865 can drive the conical spike 85 to move longitudinally synchronously, thereby crushing the clumps of protective slag that fall onto the surface of the screen plate 6, avoiding blockage, machine stoppage, and affecting work efficiency.

[0021] The control assembly 8 also includes a striking element 86, which comprises a reciprocating screw 861. The reciprocating screw 861 passes through the machine body 4 and is rotatably connected to the machine body 4. The reciprocating screw 861 is fixedly connected to the surface of the circular plate 81. When the reciprocating screw 861 rotates on the surface of the machine body 4, the circular plate 81 fixed to the surface of the reciprocating screw 861 rotates synchronously within the machine body 4. The surface of the reciprocating screw 861 is fixedly connected to the output shaft of the motor 7. The reciprocating screw 861 passes through and is threadedly connected to the moving ring 862. When the reciprocating screw 861 rotates, the moving ring 862 can move laterally on the surface of the reciprocating screw 861. The moving ring 862 is slidably connected to the support rod 863. The support rod 863 is fixedly installed on the inner wall of the connecting frame 5. The support rod 863 ensures the stability of the moving ring 862 during movement. The surface of the moving ring 862 is hinged to one end of the push rod 864, and the other end of the push rod 864 is hinged to the surface of the moving block 865. When the moving ring 862 moves, the push rod 864 can be folded, pushing the moving block 865 to move longitudinally. The moving block 865 passes through the body 4 and is slidably connected to the body 4. The inner wall of the body 4 is fixedly connected to one end of the spring 866, and the other end of the spring 866 is fixedly installed on the surface of the moving block 865. The surface of the moving block 865 is fixedly connected to the surface of the moving plate 84. When the moving block 865 is pushed, it can slide within the body 4 under the support of the spring 866. A support block 867 is fixedly installed on the inner wall of the moving block 865. The surface of the support block 867 is hinged to the movable plate 868. A knocking block 869 is fixedly installed on the surface of the movable plate 868. When the movable plate 868 is subjected to force, it can be folded on the surface of the support block 867 and the surface of the moving plate 84 is knocked by the knocking block 869.

[0022] In this invention, during use, the protective slag is placed into the machine body 4. After placement, the motor 7 on the surface of the connecting frame 5 is started. The output shaft of the motor 7 drives the reciprocating screw 861 to rotate on the surface of the machine body 4. When the reciprocating screw 861 rotates, the circular plate 81 fixed on the surface of the reciprocating screw 861 can rotate synchronously on the inner wall of the machine body 4. During the rotation of the circular plate 81, the surface of the screen plate 6 can be continuously struck by the hinged striking rod 82, thereby accelerating the screening efficiency of the screen plate 6. At the same time, when the reciprocating screw 861 rotates, the moving ring 862 can move laterally along the surface of the support rod 863. When the moving ring 862 moves, the push rod 864 hinged on the surface of the moving ring 862 can be folded, pushing the moving block 865 to move longitudinally within the machine body 4. When the moving block 865 moves, the moving plate 84 fixed on the surface of the moving block 865 can drive the cone 85 synchronously. The longitudinal movement of the movable block 865 crushes the clumps of protective slag that fall onto the surface of the screen plate 6, preventing blockages, downtime, and reduced work efficiency. When the movable block 865 moves, the inner wall of the machine body 4 abuts against one end of the movable plate 868, causing the movable plate 868 to fold against the surface of the support block 867. The striking block 869 fixed to the surface of the movable plate 868 will no longer be in contact with the surface of the movable plate 84. When the movable block 865 moves downward, the inner wall of the machine body 4 will no longer abut against the surface of the movable plate 868, allowing the movable plate 868 to reach equilibrium on the surface of the support block 867. After reaching equilibrium, the movable plate 868 can strike the surface of the movable plate 84 with the striking block 869, causing the protective slag material remaining on the surface of the cone spike 85 to fall off, facilitating subsequent screening. The screened protective slag will fall into the collection frame 2 for centralized collection.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
