Description

Technical Field

[0001] This utility model relates to the field of carbon raiser technology, specifically to a pre-extrusion crushing mechanism. Background Technology

[0002] In the smelting process of steel products, the loss of carbon elements in the molten iron is often increased due to factors such as long smelting time, holding time, and overheating time, resulting in a decrease in the carbon content of the molten iron. As a result, the carbon content in the molten iron does not reach the theoretical value expected during the smelting process. Carbon-containing substances added to make up for the carbon content lost during the steel smelting process are called carbon raisers. Before using carbon raisers, the granular carbon raisers need to be crushed with a crusher so that they can be fully absorbed.

[0003] Existing crushing mechanisms cannot screen the fine materials that meet the usage requirements after the first crushing when crushing recarburizer raw materials. This results in the fine materials that meet the usage requirements having to be crushed again together with the coarse materials that have not been completely crushed, leading to low crushing efficiency and precision. Furthermore, after crushing the recarburizer raw materials into fine dust, the existing crushing mechanisms lack a compression and packaging mechanism, causing the recarburizer to easily scatter when collected by workers, making collection very inconvenient and reducing work efficiency. To address this, we propose a pre-compression crushing mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a pre-compressible crushing mechanism to solve the problems mentioned in the background art. Existing crushing mechanisms cannot screen the fine materials that meet the usage requirements after one crushing when crushing carbon raiser raw materials. This results in the fine materials that meet the usage requirements having to be crushed a second time together with the coarse materials that have not been completely crushed. Furthermore, after crushing the carbon raiser raw materials into fine dust, the existing crushing mechanisms do not have a compression and packaging mechanism, which makes it easy for the carbon raiser to scatter when the workers collect it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-extrusion crushing mechanism, comprising a shell and an extrusion chamber, wherein the extrusion chamber is fixedly connected to the lower side of the inner cavity of the shell, an lifting chamber is fixedly connected to the left side wall of the shell, an inlet is fixedly connected to the lower side of the left side wall of the lifting chamber, a return outlet is opened on the right side wall of the lifting chamber, rotating rollers are rotatably connected between the upper and lower sides of the front and rear side walls of the lifting chamber, a conveyor belt is sleeved between the outer sides of the upper and lower rotating rollers, lifting plates are fixedly connected to the outer sides of the conveyor belt and are evenly distributed, and a first guide plate is fixedly connected to the upper side of the right side wall of the lifting chamber. A feed hopper is fixedly connected to the top of the outer shell. The left side wall of the feed hopper is connected to the first guide plate. A motor is fixedly connected to the front and rear sides of the upper right side wall of the outer shell. The left end of the power output shaft of the motor passes through the outer shell and extends into the inner cavity of the outer shell, and a crushing roller is fixedly connected thereto. The left end of the crushing roller is rotatably connected to the outer shell. A connecting hole is opened in the middle of the left side wall of the inner cavity of the outer shell. The connecting hole is connected to the return port. A filter screen is fixedly connected to the right side wall of the inner cavity of the outer shell. The left side wall of the filter screen extends into the inner cavity of the connecting hole. A second guide plate is fixedly connected around the lower side of the inner cavity of the outer shell.

[0006] As a further description of the above technical solution:

[0007] A first hydraulic rod is fixedly connected to the right side wall of the inner cavity of the extrusion chamber.

[0008] As a further description of the above technical solution:

[0009] A first pressure plate is fixedly connected to the end of the first hydraulic rod, and a second hydraulic rod is fixedly connected to the left side wall of the extrusion chamber.

[0010] As a further description of the above technical solution:

[0011] The end of the second hydraulic rod is fixedly connected to a second pressure plate, and an installation plate is fixedly connected to the upper side of the left side wall of the extrusion chamber.

[0012] As a further description of the above technical solution:

[0013] A third hydraulic rod is fixedly connected to the top of the mounting plate. The end of the third hydraulic rod passes through the mounting plate and extends to the bottom of the mounting plate, and is fixedly connected to a third pressure plate.

[0014] As a further description of the above technical solution:

[0015] The bottom left and right sides and front and back sides of the extrusion chamber are rotatably connected to a sealing plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This pre-extrusion crushing mechanism, when crushing recarburizer raw materials, feeds the recarburizer raw materials into the lifting chamber through the feed inlet. Then, the rotating roller drives the conveyor belt to move, causing the lifting plate on the conveyor belt to lift the recarburizer raw materials in the lifting chamber to the first guide plate. Subsequently, the recarburizer raw materials enter the feed chamber through the first guide plate, and then fall between the crushing rollers on both sides for crushing before falling above the filter screen. Recarburizers that meet the usage standards fall from above the filter screen into the extrusion chamber, while those that do not meet the standards roll through the filter screen to the return port and are transported again by the lifting plate for reprocessing. This allows for the screening of recarburizers that meet the usage requirements and the reprocessing of recarburizers that do not meet the usage requirements, thereby improving processing efficiency.

[0018] 2. In this pre-extrusion crushing mechanism, after the crushed carbonitrile dust falls into the extrusion chamber through the second guide plate, the first hydraulic rod extends to push the carbonitrile at the bottom of the extrusion chamber to below the third pressure plate. Then, the third hydraulic rod drives the third pressure plate to descend, and the second hydraulic rod also extends to move the second pressure plate, extruding the carbonitrile dust into blocks. Subsequently, the sealing plate rotates and opens, discharging the extruded carbonitrile dust through the discharge port. This allows for rapid collection of the crushed carbonitrile dust, improving work efficiency. Attached Figure Description

The sealing plate 240 is used to seal the extrusion chamber 200. When the crushed carbonitrile dust falls into the extrusion chamber 200 through the second guide plate 180, the first hydraulic rod 210 extends to push the carbonitrile at the bottom of the extrusion chamber 200 to below the third pressure plate 232. Then the third hydraulic rod 231 drives the third pressure plate 232 to descend, and the second hydraulic rod 220 also extends to drive the second pressure plate 221 to move, extruding the carbonitrile dust into blocks. Then the sealing plate 240 rotates and opens, and the extruded carbonitrile dust is discharged from the device through the discharge port.

[0031] In summary, the pulverized carbon raiser dust can be collected quickly, improving work efficiency;

[0032] In practical use, when processing the carbon raiser raw material, those skilled in the art feed the raw material into the lifting chamber 110 through the feed inlet 111. Then, the rotating roller 120 is started to drive the conveyor belt 121 to move, so that the lifting plate 122 on the conveyor belt 121 lifts the carbon raiser raw material in the lifting chamber 110 to the first guide plate 130. Then, the carbon raiser raw material enters the feed chamber 140 through the first guide plate 130, and then falls between the crushing rollers 151 on both sides for crushing before falling above the filter screen 170. The carbon raiser that meets the usage standards falls from above the filter screen 170 into the extrusion chamber 200. Those that do not meet the requirements are rolled through the filter screen 170 to the return port 112, and then transported again by the lifting plate 122 for reprocessing. The carbon raiser dust falling into the extrusion chamber 200 is pushed by the first hydraulic rod 210 to the bottom of the extrusion chamber 200 to below the third pressure plate 232. Then, the third hydraulic rod 231 drives the third pressure plate 232 to descend, and the second hydraulic rod 220 also extends to move the second pressure plate 221, extruding the carbon raiser dust into blocks. Then, the sealing plate 240 rotates and opens, discharging the extruded carbon raiser dust through the discharge port.
