Description

Technical Field

[0001] The utility model relates to the technical field of steel slag, in particular to a steel slag separation device. Background Technique

[0002] A steel slag separation device is a mechanical device used to process steel slag. Its main purpose is to improve the hydration activity and utilization rate of steel slag. By separating the inert mineral RO phase in the steel slag, the admixture amount of the steel slag as a cementitious material can be significantly increased. The RO phase content in the steel slag is about 20% to 30%, the average particle size is between 31 and 45 microns, the crystal grain size of the RO phase is between silicate minerals, ferroaluminate and f-CaO phase, and it has a relatively high density and hardness, mainly enriched in the coarse particle size and heavy components.

[0003] During the use of the existing steel slag separation device, although it can separate the steel slag, the steel slag is not easy to discharge during vertical grinding of the steel slag, resulting in blockage during the discharge of the steel slag. At the same time, the filling pipe cannot be automatically closed, resulting in steel slag floating into the inner wall of the filling pipe during the vertical grinding of the steel slag, causing blockage of the filling pipe. Therefore, a steel slag separation device is introduced. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a process technology and equipment for the safe application of steel slag, which has the advantages of changing the traditional discharge mode of vertical grinding and preventing blockage, and solves the problems raised in the above background technology.

[0005] The utility model provides the following technical scheme: a steel slag separation device, including a magnetic separation powder machine, an air separation machine and an auxiliary grinding agent storage tank are respectively arranged on the outer wall of the magnetic separation powder machine, a liquid extraction pump is fixedly assembled on the outer wall of the auxiliary grinding agent storage tank, one end of a filling pipe is fixedly assembled at the liquid outlet end of the liquid extraction pump, a pressure receiving component is arranged at the other end of the filling pipe, a guiding plate is fixedly assembled on the inner wall of the magnetic separation powder machine, a discharge block is fixedly assembled at the bottom of the magnetic separation powder machine, a slag discharge port is arranged on the outer wall of the discharge block, a fixing block is fixedly assembled at the top of the discharge block, a motor is fixedly assembled on the outer wall of the fixing block, one end of a rotating shaft is fixedly assembled on the power output shaft of the motor, and a grinding roller device is fixedly assembled at the other end of the rotating shaft.

[0006] As a preferred technical scheme of the utility model: a limiting groove is arranged on the inner wall of the filling pipe, a controller is fixedly assembled on the outer wall of the magnetic separation powder machine, and an air outlet pipe is fixedly assembled at the top of the magnetic separation powder machine.

[0007] As a preferred technical solution of the present utility model: The compression assembly includes a compression block, a spring is fixedly assembled on the outer wall of the compression block, one end of the connecting rod is fixedly assembled at one end of the spring where the compression block is located, and the other end of the connecting rod is fixedly assembled with a sealing plate.

[0008] As a preferred technical solution of the present utility model: The spring is fixedly assembled with the inner wall of the limiting groove, the compression block is slidably connected with the inner wall of the limiting groove, and the sealing plate is closely attached to the inner wall of the packing tube.

[0009] As a preferred technical solution of the present utility model: The grinding aid stored in the grinding aid storage tank is prepared from silica fume, and fourteen slag discharge ports are provided on the outer wall of the discharge block.

[0010] As a preferred technical solution of the present utility model: There are three discharge blocks, and the three discharge blocks are respectively located at the bottom of the magnetic separation powder machine. The magnetic separation powder machine, the air separator, the liquid extraction pump, and the motor are all electrically connected to the controller.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For this steel slag separation equipment, by the controller sending a signal, the power output shaft of the motor rotates after receiving the signal. The motor drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the grinding roller device to rotate. When the grinding roller device rotates, it grinds the steel slag, making the steel slag finely crushed. At the same time, through the fourteen slag discharge ports provided on the outer wall of the discharge block, it is convenient to discharge the ground steel slag, thus changing the discharge method of the traditional vertical mill.

[0013] 2. For this steel slag separation equipment, by the controller sending a signal, the liquid extraction pump extracts the grinding aid in the grinding aid storage tank after receiving the signal. The liquid extraction pump pumps the liquid in the grinding aid storage tank into the inner wall of the packing tube. When the liquid enters the inner wall of the packing tube, it presses the compression block, and the compression block moves on the inner wall of the limiting groove under the pressure. When the compression block moves, it drives the connecting rod and the sealing plate to move. When the sealing plate moves out of the inner wall of the packing tube, the combustion aid flows into the inner wall of the discharge block for grinding, making the grinding effect of the grinding roller device on the steel slag better. At the same time, when the liquid supply to the inner wall of the discharge block is cancelled, the elastic potential energy of the spring is released, and the sealing plate re-fits the inner wall of the packing tube, thus preventing materials from entering the inner wall of the packing tube and causing blockage during the operation of the equipment.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. The air separation machine and the magnetic separation powder machine are existing equipment, and the models are positive pressure rotary drum air separation machine and centrifugal powder separator.

[0022] Please refer to Figure 1 - Figure 5 , a steel slag separation device, including a magnetic separation powder machine 1. An air separation machine 4 and a grinding aid storage box 5 are respectively arranged on the outer wall of the magnetic separation powder machine 1. A liquid extraction pump 6 is fixedly assembled on the outer wall of the grinding aid storage box 5. One end of a filler pipe 7 is fixedly assembled at the liquid outlet end of the liquid extraction pump 6. The other end of the filler pipe 7 is provided with a compression component 8. A guide plate 9 is fixedly assembled on the inner wall of the magnetic separation powder machine 1. A discharge block 10 is fixedly assembled at the bottom of the magnetic separation powder machine 1. A slag discharge port 11 is opened on the outer wall of the discharge block 10. A fixed block 12 is fixedly assembled at the top of the discharge block 10. A motor 13 is fixedly assembled on the outer wall of the fixed block 12. One end of a rotating shaft 14 is fixedly assembled on the power output shaft of the motor 13. The other end of the rotating shaft 14 is fixedly assembled with a grinding roller device 15.

[0023] In the above structure, by sending a signal through the controller 2, after the motor 13 receives the signal, its power output shaft immediately starts to rotate. This rotation action further drives the rotating shaft 14 to rotate synchronously. During the rotation of the rotating shaft 14, it drives the roller device 15 to rotate together. When the roller device 15 rotates, it grinds the steel slag to achieve fine crushing of the steel slag. At the same time, by using the fourteen slag discharge ports 11 opened on the outer wall of the discharge block 10, the discharge process of the ground steel slag is optimized, and the discharge method of the traditional vertical mill is innovated. In addition, the guiding plate 9 is used to accurately guide the sorted materials to ensure that the materials can accurately enter each discharge block 10.

[0024] In a preferred embodiment: a limiting groove 16 is provided on the inner wall of the filler pipe 7, a controller 2 is fixedly assembled on the outer wall of the magnetic separator 1, and an air outlet pipe 3 is fixedly assembled on the top of the magnetic separator 1.

[0025] In the above structure, the controller 2 is used to control the equipment to work, the air outlet pipe 3 is used to discharge the gas generated by the air separator 4, and the limiting groove 16 is used to place the pressure-bearing component 8.

[0026] In a preferred embodiment: the pressure-bearing component 8 includes a pressure-bearing block 801, a spring 802 is fixedly assembled on the outer wall of the pressure-bearing block 801, one end of the pressure-bearing block 801 where the spring 802 is located is fixedly assembled with one end of a connecting rod 803, and the other end of the connecting rod 803 is fixedly assembled with a sealing plate 804.

[0027] In the above structure, by sending a signal through the controller 2, after the liquid extraction pump 6 receives the signal, it extracts the grinding aid in the grinding aid storage tank 5. Subsequently, the liquid in the grinding aid storage tank 5 is introduced into the inner wall of the filler pipe 7 through the liquid extraction pump 6. During the process of the liquid entering the inner wall of the filler pipe 7, pressure is applied to the pressure-bearing block 801. After the pressure-bearing block 801 is subjected to pressure, it moves on the inner wall of the limiting groove 16. At the same time, as the pressure-bearing block 801 moves, it will drive the connecting rod 803 and the sealing plate 804 to move synchronously. When the sealing plate 804 moves out of the inner wall of the filler pipe 7, the combustion aid will flow into the inner wall of the discharge block 10 for grinding treatment to improve the grinding efficiency of the roller device 15 on the steel slag. When the liquid supply to the inner wall of the discharge block 10 stops, the elastic potential energy of the spring 802 is released, so that the sealing plate 804 fits back to the inner wall of the filler pipe 7, effectively preventing the blockage problem caused by materials entering the inner wall of the filler pipe 7 during the operation of the equipment.

[0028] In a preferred embodiment: the spring 802 is fixedly assembled with the inner wall of the limiting groove 16, the pressure-bearing block 801 is slidably connected with the inner wall of the limiting groove 16, and the sealing plate 804 is in close fit with the inner wall of the filler pipe 7.

[0029] In the above structure, the compression component 8 is limited by the limiting groove 16, so that the compression component 8 will not separate from the inner wall of the packing pipe 7 when placed. The sealing plate 804 is closely attached to the inner wall of the packing pipe 7, so that the grinding aid will not flow out from the liquid outlet end of the packing pipe 7 when the sealing plate 804 is placed on the inner wall of the packing pipe 7.

[0030] In a preferred embodiment: the grinding aid inside the grinding aid storage tank 5 is prepared from silica fume, and fourteen slag discharge ports 11 are provided on the outer wall of the discharge block 10.

[0031] In the above structure, the grinding aid is made from silica fume, which helps in grinding and activating the activity of steel slag during the grinding process. Through the fourteen slag discharge ports 11, the ground steel slag can be discharged better.

[0032] In a preferred embodiment: there are three discharge blocks 10, and the three discharge blocks 10 are respectively located at the bottom of the magnetic separator 1. The magnetic separator 1, the air separator 4, the liquid extraction pump 6, and the motor 13 are all electrically connected to the controller 2.

[0033] In the above structure, there are three discharge blocks 10, and the three discharge blocks 10 are respectively the iron outlet, the RO outlet, and the ultra-fine material outlet, so as to realize the separation of steel slag. By sending a signal through the controller 2, the equipment starts to work after receiving the signal.

[0034] Working principle: By sending an instruction through the controller 2, after the motor 13 receives the signal, its power output shaft starts to rotate. This rotation further drives the rotating shaft 14 to rotate through the motor 13, and the rotating shaft 14 drives the grinding roller device 15 to rotate synchronously during the rotation process. When the grinding roller device 15 rotates, it grinds the steel slag to achieve fine crushing of the steel slag. At the same time, fourteen channel slag discharge ports 11 are provided on the outer wall of the discharge block 10. These channel designs are aimed at optimizing the discharge process of the ground steel slag, thus improving the discharge method of the traditional vertical mill. When the controller 2 sends an instruction, the liquid extraction pump 6 receives the signal and starts, responsible for extracting the grinding aid from the grinding aid storage tank 5. Subsequently, the liquid extraction pump 6 injects the extracted liquid grinding aid into the inner wall of the packing pipe 7. After the liquid enters the packing pipe 7, it applies pressure to the piston compression block 801, forcing it to move inside the inner wall of the limiting groove 16. The movement of the piston compression block 801 drives the connecting component connecting rod 803 and the sealing plate 804 to move together. When the sealing plate 804 moves out of the inner wall of the packing pipe 7, the grinding aid can flow into the inner wall of the discharge block 10, providing assistance for the grinding process of the steel slag to enhance the grinding effect. When it is necessary to stop supplying liquid to the inner wall of the discharge block 10, the elastic potential energy of the spring 802 is released, pushing the sealing plate 804 to closely fit the inner wall of the packing pipe 7 again, effectively preventing the situation that materials seep into the inner wall of the packing pipe 7 and cause blockage during the working process of the equipment.

[0035] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
