[0028] The present invention will be further described below with reference to specific embodiments.

[0029] Example 1

[0030] like Figure 1 、 Figure 2 、 Figure 3 As shown, the converter refined slag recycling device of this embodiment includes a crushing box 100, a feeding port 101 is provided on the top of the crushing box 100, a crushing roller 102, a screening plate 104 and a shovel 107 are distributed in sequence in the upper and lower parts of the crushing box 100, the crushing roller 102 is provided with a surrounding crushing cone 103, and a first discharge port 112 and a second discharge port 113 are provided on the outside of the crushing box 100 respectively. The first discharge port 112 is arranged at the bottom of the crushing box 100 and corresponds to the position of the shovel 107. The shovel 107 pushes the material to be discharged through the first discharge port 112; the position of the second discharge port 113 corresponds to the position of the screening plate 104, and the screening plate 104 is also provided with a scraper plate 105. The scraper plate 105 pushes the material remaining on the screening plate 104 to the second discharge port 113 for discharge. During use, the material is added through the feeding port 101, and the crushing roller 102 is started to rotate at a high speed to crush the material. The crushed material is screened by the screening plate 104 and falls into the bottom of the crushing box 100. The shovel 107 can be started at a fixed time to push the crushed material and discharge it through the first discharge port 112; the material that is not completely crushed will remain on the screening plate 104, and the scraper plate 105 can be started to push the remaining material to the second discharge port 113 for discharge, and then put it back into the crushing box 100 for crushing again.

[0031] Specifically, in this embodiment, a motor box is installed on the outer wall of the crushing box 100, which uses a motor to drive the vertical rotation of the crushing roller 102. A crushing cone 103 is welded to the surface of the crushing roller 102. The top feed port 101 is equipped with a sealed sliding cover connected to a rotating shaft for easy opening and closing. In this embodiment, the first and second discharge ports 112 and 113 are respectively located on adjacent side walls of the crushing box 100. The scraping direction of the scraper 105 is perpendicular to the scraping direction of the scraper 107.

[0032] In this embodiment, the screening plate 104 is a movable screening plate, and the crushing box 100 is provided with a horizontal moving assembly for driving the screening plate 104 to reciprocate horizontally within the crushing box 100, thereby improving the screening efficiency of the screening plate and avoiding the phenomenon of clogging of the screening holes. Specifically, a fixed frame 110 is provided on both sides of the crushing box 100, and a movable chute is provided in the fixed frame 110. The two sides of the screening plate 104 are correspondingly embedded in the movable chute, and one end of the screening plate 104 is connected to the horizontal moving assembly. The horizontal moving assembly drives the screening plate 104 to reciprocate within the fixed frame 110. The horizontal moving assembly can adopt a power cylinder assembly or other conventional linear drive power assembly in the industry, which can drive the screening plate 104 to reciprocate horizontally, and will not be described in detail here. Correspondingly, an avoidance cavity is provided on the side wall of the crushing box 100 for the reciprocating movement of the screening plate 104, and the avoidance cavity extends outward and protrudes from the side wall of the crushing box 100; one end of the screening plate 104 extends into the avoidance cavity, and the other end extends into the second discharge port 113, that is, during the horizontal movement of the screening plate 104, its two ends are still moving in the avoidance cavity and the second discharge port 113 respectively, to prevent the material from falling directly to the bottom without being screened.

[0033] Furthermore, to enhance the material pulverization effect, in this embodiment, the crushing cone 103 and the screening plate 104 are brought into close proximity during the pulverization process to achieve a crushing and squeezing effect on the material. Accordingly, the crushing box 100 is equipped with a height adjustment assembly for driving the screening plate 104 and the scraper plate 105 to vary in height within the crushing box 100. This allows for controlled height clearance between the screening plate 104 and the crushing cone 103 when concentrated scraping is required, ensuring sufficient scraping operation for the scraper plate 105. Specifically, the bottom of the fixed frame 110 is connected to the height adjustment assembly, which drives the fixed frame 110 and the screening plate 104 to vary in height. In practice, the height adjustment assembly can be implemented using different mounting holes. Specifically, the height adjustment assembly includes connecting screws provided at the ends of the fixed frame 110 and corresponding mounting holes located at different heights on the sidewall of the crushing box 100. The ends of the fixed frame 110 are mounted in the mounting holes at different heights and tightened with nuts to achieve height adjustment, thereby controlling the height change of the screening plate 104. Similarly, the height moving component can also adopt a power cylinder component or other conventional power parts in the industry, which can drive the fixed frame 110 to perform reciprocating height adjustment. The side wall of the crushing box 100 is correspondingly provided with a height slide groove that cooperates with the fixed frame 110, which will not be described in detail here.

[0034] like Figure 3As shown, in this embodiment, a support frame 111 is also provided on the fixed frame 110, and a movable slide groove is also provided in the support frame 111. A connecting plate 106 is provided on the top of the scraper plate 105, and both ends of the connecting plate 106 are respectively embedded in the movable slide groove. A scraper moving component is provided in the crushing box 100 and is connected to the connecting plate 106, which is used to drive the connecting plate 106 and the scraper plate 105 to move back and forth horizontally. The scraper moving component can also adopt a power cylinder component or other conventional power parts in the industry, which can drive the connecting plate 106 and the scraper plate 105 to move back and forth horizontally to push the material, which will not be described in detail here.

[0035] Furthermore, in this embodiment, the scraper 107 is also equipped with a horizontal moving assembly to drive its horizontal reciprocating movement to push the material, which can be specifically a power cylinder assembly or other conventional power parts in the industry, such as Figure 1 As shown, in this embodiment, an anti-sticking telescopic belt 108 is provided at the top of the scraper 107, and the other end of the anti-sticking telescopic belt 108 is fixed on the telescopic belt reel 109 on the inner wall of the crushing box 100, and the height of the telescopic belt reel 109 is higher than the height of the top of the scraper 107; the scraper 107 pushes the material in the direction away from the telescopic belt reel 109. The anti-sticking telescopic belt 108 can be directly made of an elastic belt, which can be extended and retracted with the reciprocating movement of the shovel 107. During the material crushing and screening stage, the shovel 107 is at the end away from the first discharge port 112. At this time, the anti-sticking telescopic belt 108 is in a retracted state, and an inclined guide belt is formed between the top of the shovel 107 and the inner wall of the crushing box 100, which can guide the falling crushed materials to the side of the shoveling direction of the shovel 107 to avoid scattering and affecting the pushing of materials; when the shovel 107 gradually approaches the first discharge port 112 for pushing materials, the anti-sticking telescopic belt 108 is elastically stretched accordingly; a vibrator can also be set on the back side of the anti-sticking telescopic belt 108. In practice, the anti-sticking stretch tape 108 can also adopt a reel-winding structure, that is, the stretch tape reel 109 can be controlled to rotate by motor power, thereby driving the unfolding and rewinding states of the anti-sticking stretch tape 108. During the material crushing and screening stage, the anti-sticking stretch tape 108 is rolled on the stretch tape reel 109. During the material pushing process, the stretch tape reel 109 rotates so that the anti-sticking stretch tape 108 can be unfolded accordingly.

[0036] The method of using the converter refined slag recycling device of this embodiment is to feed the material into the crushing box 100 through the feeding port 101, start the crushing roller 102 to rotate and use the crushing cone 103 to crush the material, and the screening plate 104 slides back and forth to screen. The crushed material falls to the bottom of the crushing box 100 and is pushed to the first discharge port 112 for discharge through the shovel 107; if there is any uncrushed material remaining, lower the height position of the screening plate 104, start the scraper plate 105 to push the material remaining on the screening plate 104, and after being discharged through the second discharge port 113, it is fed back into the crushing box 100 for further crushing.

[0037] The examples described in the present invention are merely descriptions of the preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the scope of protection of the present invention.
