Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a rolling mill for processing high-temperature alloy slag. Background Technology

[0002] After a certain period of time, once the ferrochrome alloy slag has reached a certain quantity (approximately 30t or 60t), to prevent excessive slag buildup, a crushing and rolling mill can be activated to prioritize the crushing of the slag already flowing into the slag bed. During the crushing and rolling process, a small amount of water can be sprayed onto the treated alloy slag using the mill's built-in spray system to cool it down. After a certain number of treatment cycles, once the slag temperature is controlled to drop to 700-800℃, the crushing and rolling mill can reverse its direction, pushing the pre-treated 30t or 60t of slag into the crushing bed port. A loader or slag truck then transports the slag to a designated area. After this initial treatment, the crushing and rolling mill repeats the crushing and rolling process on subsequent alloy slag already flowing into the slag bed until all slag is processed and operation ceases.

[0003] The roller crusher moves through the compaction zone and activates its rollers to crush the laid-out molten slag. This cools and granulates the high-temperature molten slag, providing fine-grained steel slag and a stable temperature for the next process. This process takes approximately 15 minutes. After a certain period of crushing, the rollers are reversed, pushing the processed slag into the material feeding and screening port. Small pieces fall into the small material hopper, and large pieces fall into the large material hopper. The temperature is maintained at a level free of molten slag when the slag exits the tank.

[0004] In existing crushing presses, the crushed slag is directly discharged to the screen opening for screening. During the slag's fall, the height of the discharge opening is not adjustable, resulting in dust falling into the screening device and impact damage to the screening device. Furthermore, during the crushing process, the crushing press is equipped with a spray cooling system, which generates a large amount of dust and smoke, polluting the surrounding environment and posing a significant health hazard if inhaled. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a rolling mill for processing high-temperature alloy slag is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a rolling mill for processing high-temperature alloy slag is provided, comprising: a rolling mill bed, a feeding plate provided on the outer side of the rolling mill bed, and drive components connected to both ends of the feeding plate, the drive components including a drive box fixed to the outer wall of the rolling mill bed, the outer wall of the rolling mill bed being provided with a steel rail and a through pipe, the inner side of the through pipe being connected to a cavity opened in the inner wall of the rolling mill bed through a connecting pipe, and a filter box being connected to one end of the through pipe, while a vacuum pump being connected to one side of the filter box.

[0007] Furthermore, the bottom layer of the rolling mill bed is a concrete layer, and an insulation board is provided on the upper side of the concrete layer, and a pebble layer is provided on the upper side of the insulation board, while a slag layer is provided on the upper side of the pebble layer.

[0008] Furthermore, a discharge port is provided on one side of the rolling mill bed, and the discharge plate is hinged to the lower outer edge of the discharge port.

[0009] Furthermore, the drive box is equipped with a motor, and the output shaft of the motor is connected to a drive shaft, and the outer end of the drive shaft is connected to a turntable.

[0010] Furthermore, an eccentric shaft is connected to the side of the turntable facing the feed plate, and the other end of the eccentric shaft is connected to the edge of the feed plate.

[0011] Furthermore, a filter screen is provided inside the cavity, and the cavity is connected to the filter box through a connecting pipe and a through pipe.

[0012] Furthermore, the filter box is equipped with an air filter element and an activated carbon fiber mesh plate.

[0013] The beneficial effects of this utility model are as follows: 1. After crushing is completed, the motor inside the drive box of the drive assembly is started, which drives the drive shaft to rotate, thereby rotating the turntable at a certain angle. The turntable then drives the eccentric shaft to rotate, thereby opening the feed plate at an appropriate angle. The appropriate tilt angle of the feed plate at this time is adapted to the height of the screening device below. In this way, the dust and impact force during the discharge process can be reduced during the discharge process, avoiding the impact damage and the stirring up of a large amount of dust caused by the material falling directly from the feed port. 2. During the crushing process, the air pump is started to generate suction inside the cavity through the through-pipe and connecting pipe, and then the smoke generated by the spray cooling is drawn in. The smoke is filtered by the internal air filter and activated carbon fiber mesh in the filter box, and then discharged into the environment, thus purifying the smoke generated during cooling and avoiding pollution of the surrounding environment and harm to the human body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 As shown, this utility model provides a rolling mill for processing high-temperature alloy slag, including: a rolling mill body 1, a feeding plate 11 on the outer side of the rolling mill body 1, and a drive assembly 2 connected to both ends of the feeding plate 11. The drive assembly 2 includes a drive box 21 fixed to the outer wall of the rolling mill body 1. The outer wall of the rolling mill body 1 is provided with a rail 12 and a through pipe 13. The inner side of the through pipe 13 is connected to a cavity 151 opened in the inner wall of the rolling mill body 1 through a connecting pipe 131. One end of the through pipe 13 is connected to a filter box 132, and a vacuum pump 133 is connected to one side of the filter box 132.

[0021] In this embodiment, the steel rail 12 on the outer side of the roller bed 1 is used to install a roller crushing vehicle. The roller crushing vehicle moves across the upper side of the roller bed 1 and discharges the slag by flipping the crushing roller after crushing.

[0022] Specifically, the drive assembly 2 is provided with two sets symmetrical about the feed plate 11, which enhances the stability of the connection with the feed plate 11 and the support stability during material discharge.

[0023] Specifically, the cavity 151 is formed on the inner wall of the three sides of the rolling mill bed 1, excluding the inner wall of the feed plate 11 side, and the cavity 151 is set along the length and width of the inner wall of the rolling mill bed 1, thereby increasing the contact area with the inner space of the rolling mill bed 1, and thus improving the suction effect of smoke and dust.

[0024] Specifically, the air pump 133 and the filter box 132 are both installed on the outer wall of the rolling mill bed 1, and the air pump 133 and the filter box 132 are connected by a pipe, with the air outlet of the air pump 133 placed in the external environment.

[0025] like Figure 1 and Figure 4 In the compaction bed 1, the bottom layer is a concrete layer 19, and the upper side of the concrete layer 19 is provided with a heat insulation board 18, and the upper side of the heat insulation board 18 is provided with a pebble layer 17. At the same time, the upper side of the pebble layer 17 is provided with a slag layer 16. A discharge port 14 is opened on one side of the compaction bed 1, and the discharge plate 11 is hinged to the lower edge of the outer side of the discharge port 14. A motor is provided inside the drive box 21, and the output shaft of the motor is connected to a drive shaft 22. The outer end of the drive shaft 22 is connected to a turntable 23. An eccentric shaft 24 is connected to the side of the turntable 23 facing the discharge plate 11, and the other end of the eccentric shaft 24 is connected to the edge of the discharge plate 11. A filter screen 15 is provided inside the cavity 151, and the cavity 151 is connected to the filter box 132 through a connecting pipe 131 and a through pipe 13. An air filter element and an activated carbon fiber mesh are provided inside the filter box 132.

[0026] Specifically, the sidewall of the rolling mill bed 1 includes an outer concrete layer 19 and an inner heat insulation board 18. At the same time, by setting a pebble layer 17 and a slag layer 16, the friction and heat insulation effect at the bottom are enhanced.

[0027] As a preferred embodiment, the pebble layer 17 and the slag layer 16 enhance the crushing effect by increasing friction. The slag layer 16 consists of alloy slag material remaining after each crushing. During compression crushing, it can enhance the buffer protection of the bottom, thereby protecting the roller bed 1.

[0028] Specifically, the motors in the two drive boxes 21 are set to start synchronously to maintain the stable rotation of the feed plate 11, and the drive box 21 is provided with an inclined triangular plate on the lower side. The drive box 21 is installed on the outer wall of the rolling mill bed 1 with a certain distance space through the triangular plate.

[0029] Specifically, the through pipe 13 is fixed around the outer wall of the rolling mill bed 1. The through pipe 13 is set as an integral pipe with a diameter larger than that of the connecting pipe 131.

[0030] Specifically, the top of the filter box 132 has two independent mounting holes, and the air filter element and activated carbon fiber mesh are both inserted into the filter box 132 through the mounting holes. The mounting holes are equipped with removable covers to facilitate the disassembly of the air filter element and activated carbon fiber mesh.

[0031] During operation, after crushing, the motor inside the drive box of the drive assembly is activated, causing the drive shaft to rotate, which in turn rotates the turntable at a certain angle. The turntable then rotates the eccentric shaft, opening the feed plate at an appropriate angle. The tilt angle of the feed plate is adapted to the height of the lower screening device, thus reducing dust and impact during the discharge process and preventing direct impact damage and dust generation from the feed opening. During crushing, the air pump is activated, generating suction inside the cavity through the through-pipe and connecting pipe. The smoke generated by the spray cooling is then drawn in. The smoke is filtered through the internal air filter and activated carbon fiber mesh in the filter box before being discharged into the environment, thus purifying the smoke generated during cooling and preventing pollution of the surrounding environment and harm to human health.

[0032] The rolling mill bed for processing high-temperature alloy slag of this utility model can effectively solve the problems mentioned in the background technology. Based on the existing rolling mill bed technology for processing high-temperature alloy slag, it can adjust the angle of the rolling mill bed discharge process to prevent direct material falling and causing dust and impact damage. At the same time, it is convenient to extract and treat the dust and smoke generated during the crushing process to avoid polluting the surrounding environment.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
