Description

Technical Field

[0001] The invention belongs to the technical field of steel slag magnetic separation and crushing, and specifically refers to a steel slag iron sheet crushing magnetic separator and a use method thereof. Background Art

[0002] Steel slag needs to be crushed before magnetic separation. The crushed steel slag is evenly fed into the magnetic separation area through the feeder. Under the strong magnetic force, magnetic iron pieces and other magnetic materials are attracted to the surface of the magnetic field system and separated. At the same time, non-magnetic materials flow out along the separation grid to achieve clean separation of steel slag.

[0003] The existing crushing magnetic separators have the following problems: The existing crushing magnetic separator uses a roller extrusion method to crush steel slag. When the rollers encounter steel slag blocks with relatively high hardness, the steel slag blocks will hinder the rotation of the rollers, increase the driving load of the crushing motor, and interfere with the normal rotation and crushing operation of the rollers, thereby reducing the use efficiency of the crushing magnetic separator. Therefore, it cannot meet the existing use requirements of the crushing magnetic separator. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a steel slag iron sheet crushing magnetic separator and its use method which can adjust the spacing between 15 according to the pressure between the extrusion cylinders, thereby crushing harder steel slag while reducing the driving load of the crushing motor.

[0005] The technical scheme adopted in this scheme is as follows: A steel slag and iron sheet crushing magnetic separator proposed in this scheme includes a base, legs, a main body assembly, an extrusion type crushing mechanism and a load-controlled collecting mechanism. Multiple groups of legs are arranged on the bottom wall of the base, the main body assembly is arranged on the upper wall of the base, the extrusion type crushing mechanism is arranged on the main body assembly, and the load-controlled collecting mechanism is arranged on the extrusion type crushing mechanism. The extrusion type crushing mechanism includes a driving mechanism and an extrusion mechanism. The driving mechanism is arranged on the main body assembly, and the extrusion mechanism is arranged inside the main body assembly. The load-controlled collecting mechanism includes a force measuring mechanism, a magnetic attraction mechanism and a claw mechanism. The force measuring mechanism is arranged on the side wall of the driving mechanism, the magnetic attraction mechanism is arranged inside the main body assembly, and the claw mechanism is arranged on the extrusion mechanism.

[0006] As a further preferred embodiment of the present invention, the main body component includes a groove, a crushing barrel, a raised arc plate and a crushing port. The groove is arranged in the middle position of the upper wall of the base, and the groove is arranged through. The crushing barrel is arranged inside the groove, the raised arc plate is arranged on the bottom wall of the crushing barrel, and the crushing port is arranged on the upper wall of the crushing barrel.

[0007] When in use, the steel slag to be magnetically separated is placed into the crushing cylinder through the crushing port for crushing.

[0008] Preferably, the driving mechanism includes a U-shaped block, a sliding support, a driving motor, a driving shaft and a crushing mechanism, the U-shaped blocks are symmetrically arranged on the inner walls of both sides of the crushing barrel in a group of two, the sliding support is slidably arranged on the end of the U-shaped block away from the inner wall of the crushing barrel, the driving motor is arranged on the side of the sliding support away from the U-shaped block, the driving shaft is rotatably arranged between the sliding supports, and the power end of the driving motor is connected to the driving shaft; the crushing mechanism includes an extrusion barrel, a rod block and a crushing rod, the extrusion barrel is arranged on the outside of the driving shaft, the rod block is arranged on the outside of the driving shaft inside the extrusion barrel, and multiple groups of crushing rods penetrate the extrusion barrel and are arranged on the side wall of the rod block.

[0009] When in use, the extrusion cylinder placed inside the crushing cylinder is symmetrically arranged, and the crushing rods on the symmetrically arranged side walls of the extrusion cylinder are staggered. The extrusion cylinder uses the staggered spacing between the crushing rods to crush the steel slag entering the crushing cylinder. The driving motor drives the driving shaft to rotate through the power end, and the driving shaft rotates through the extrusion cylinder. The symmetrically arranged extrusion cylinders rotate clockwise and counterclockwise respectively, and the extrusion cylinders rotate relatively. The driving shaft drives the crushing rods through the dividing rod blocks to extrude and crush the steel slag entering between the extrusion cylinders. The crushed steel slag falls to the bottom of the crushing cylinder under the diversion of the convex arc plate.

[0010] Specifically, the force measuring mechanism includes a hydraulic cylinder and a pressure sensor, the hydraulic cylinder is arranged at one end of the U-shaped block close to the inner wall of the crushing barrel, the power end of the hydraulic cylinder is connected to the sliding support, the pressure sensor is arranged on the side wall of the hydraulic cylinder, and the detection end of the pressure sensor passes through the cylinder body of the hydraulic cylinder and is arranged inside it; the magnetic attraction mechanism includes a partition wear-resistant plate, a magnetic attraction port and an adsorption electromagnet, the partition wear-resistant plates are symmetrically arranged on the inner walls on both sides of the crushing barrel, multiple groups of the magnetic attraction ports are arranged on the bottom wall of the partition wear-resistant plates, and multiple groups of the adsorption electromagnets are arranged through the side of the partition wear-resistant plates away from the extrusion barrel; the claw mechanism includes a sliding groove, a lengthening spring, an extension rod and an extrusion iron ball, the sliding groove is arranged on the side of the crushing rod away from the dividing rod block, the sliding groove is open at one end, the extension rod is slidably arranged inside the sliding groove, the extrusion iron ball is arranged on the side of the extension rod away from the crushing rod, the lengthening spring is arranged between the extension rod and the inner wall of the sliding groove, and the lengthening spring is shortened.

[0011] When in use, the power end of the hydraulic cylinder extends to push the sliding support to slide along the inner wall of the U-shaped block. The sliding support drives the extrusion cylinder to move relative to each other through the driving shaft. The extrusion cylinder drives the crushing rods to be placed crosswise, and the distance between the crushing rods and the extrusion cylinder is shortened. When the harder slag block enters between the extrusion cylinders for crushing, due to its greater hardness, the slag block is stuck between the extrusion cylinders, and the rotation speed of the extrusion cylinders slows down. The slag block moves to the straight line distance between the extrusion cylinders as the extrusion cylinders rotate slowly. At this time, the volume of the slag block is larger, and the extrusion cylinder applies pressure to the sliding support through the driving shaft. The sliding support slides along the U-shaped block to apply pressure to the hydraulic cylinder, and the pressure inside the hydraulic cylinder body increases. The detection threshold of the pressure sensor is pre-set, and the pressure sensor monitors the pressure inside the hydraulic cylinder through the detection end. When the pressure inside the hydraulic cylinder body reaches the threshold pre-set by the pressure sensor, the power end of the hydraulic cylinder shortens and drives the sliding support. Sliding along the U-shaped block, the sliding support drives the extrusion cylinder to move relative to each other through the driving shaft, and the spacing between the extrusion cylinders is increased to facilitate the passage of steel slag blocks with greater hardness. The harder steel slag blocks fall into the upper wall of the separating wear-resistant plate under the diversion of the convex arc plate, and the adsorption electromagnet is energized to generate magnetism. The adsorption electromagnet is fixed between the inner wall of the crushing cylinder and the separating wear-resistant plate. The adsorption electromagnet uses magnetic force to adsorb the extruded iron ball through the magnetic suction port, and the extruded iron ball slides along the sliding groove using the deformation of the lengthened spring, and the extension rod slides out of the sliding groove, and the extension rod is stretched to fit the side wall of the separating wear-resistant plate. The adjacent extension rod picks up the uncrushed steel slag blocks placed on the upper wall of the separating wear-resistant plate during the rotation process, and the steel slag block crushing extension rod rotates to the position of the crushing cylinder close to the crushing port, and then the steel slag blocks fall between the extrusion cylinders under the action of their own gravity for re-crushing, thereby completing the crushing operation of the steel slag under the condition of reducing the driving load of the driving motor.

[0012] Wherein, a controller is provided on the side wall of the base.

[0013] Preferably, the controller is electrically connected to the drive motor, the hydraulic cylinder, the pressure sensor and the adsorption electromagnet respectively.

[0014] A method for using a steel slag iron sheet crushing magnetic separator, the steps are as follows: Step 1: The magnetically separated steel slag is placed into the crushing tube through the crushing port for crushing; Step 2: The driving motor drives the driving shaft to rotate through the power end, and the driving shaft rotates through the extrusion barrel. The symmetrically arranged extrusion barrels rotate clockwise and counterclockwise respectively. The extrusion barrels rotate relatively. The driving shaft drives the crushing rod through the rod block to extrude and crush the steel slag entering between the extrusion barrels. Step 3: Preset the detection threshold of the pressure sensor. The pressure sensor monitors the pressure inside the hydraulic cylinder through the detection end. When the pressure inside the hydraulic cylinder reaches the threshold preset by the pressure sensor, the power end of the hydraulic cylinder shortens to drive the sliding support to slide along the U-shaped block. The sliding support drives the extrusion cylinder to move relative to each other through the driving shaft. The spacing between the extrusion cylinders increases, which facilitates the passage of the steel slag block with greater hardness. Step 4: The adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet is fixed between the inner wall of the crushing cylinder and the partition wear-resistant plate. The adsorption electromagnet uses magnetic force to adsorb the extruded iron ball through the magnetic suction port. The extruded iron ball slides along the sliding groove using the deformation of the lengthened spring, and the extension rod slides out of the sliding groove. The extension rod is stretched and fits the side wall of the partition wear-resistant plate. The adjacent extension rods pick up the uncrushed slag blocks placed on the upper wall of the partition wear-resistant plate during the rotation process. The slag block crushing extension rod rotates to the position of the crushing cylinder close to the crushing port, and then the slag blocks fall into the extrusion cylinder under the action of their own gravity for re-crushing.

[0015] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a combination of a multi-segment crushing column and a pressure detection structure. Through the main body assembly, the extrusion type crushing mechanism and the load-controlled collecting mechanism, the driving mechanism, the extrusion crushing mechanism, the force measuring mechanism, the magnetic suction mechanism and the claw mechanism are used in coordination. Under the condition of reducing the rotation load of the magnetic suction mechanism, the steel slag blocks with relatively high hardness can be cyclically crushed. On the one hand, the crushing efficiency of the steel slag inside the crushing cylinder is guaranteed. On the other hand, the normal operation of the driving motor can be guaranteed to prevent the steel slag with relatively high hardness from being stuck between the extrusion cylinders and affecting the normal crushing operation of the extrusion cylinders for the steel slag. The volume of the steel slag blocks is relatively large, and the extrusion cylinders are The pressing cylinder applies pressure to the sliding support through the driving shaft, and the sliding support slides along the U-shaped block to apply pressure to the hydraulic cylinder. The pressure inside the hydraulic cylinder body increases, and the detection threshold of the pressure sensor is set in advance. The pressure sensor monitors the pressure inside the hydraulic cylinder through the detection end. When the pressure inside the hydraulic cylinder body reaches the threshold preset by the pressure sensor, the power end of the hydraulic cylinder shortens and drives the sliding support to slide along the U-shaped block. The sliding support drives the extrusion cylinder to move relative to each other through the driving shaft. The spacing between the extrusion cylinders increases, which facilitates the passage of steel slag blocks with greater hardness. The harder steel slag blocks fall into the upper wall of the separating wear-resistant plate under the diversion of the raised arc plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A method for using a steel slag iron sheet crushing magnetic separator, the steps are as follows: Step 1: The magnetically separated steel slag is placed into the crushing tube 5 through the crushing port 7 for crushing; Step 2: The driving motor 12 drives the driving shaft 13 to rotate through the power end, and the driving shaft 13 rotates through the extrusion cylinder 15.

The extrusion cylinders 15 rotate relatively, and the driving shaft 13 drives the crushing rod 17 through the rod block 16 to extrude and crush the steel slag entering between the extrusion cylinders 15; Step 3: Preset the detection threshold of the pressure sensor 21. The pressure sensor 21 monitors the pressure inside the hydraulic cylinder 20 through the detection end. When the pressure inside the cylinder body of the hydraulic cylinder 20 reaches the threshold preset by the pressure sensor 21, the power end of the hydraulic cylinder 20 shortens to drive the sliding support 11 to slide along the U-shaped block 10. The sliding support 11 drives the extrusion cylinder 15 to move relative to each other through the driving shaft 13. The spacing between the extrusion cylinders 15 increases, which is convenient for the steel slag blocks with greater hardness to pass through. Step 4: The adsorption electromagnet 25 is energized to generate magnetism, and the adsorption electromagnet 25 is fixed between the inner wall of the crushing cylinder 5 and the partition wear-resistant plate 23. The adsorption electromagnet 25 uses magnetic force to adsorb the extruded iron ball 30 through the magnetic suction port 24.

The rotation of the slag block crushing extension rod 29 reaches the position of the crushing cylinder 5 close to the crushing port 7, and then the slag blocks fall into the extrusion cylinder 15 under the action of their own gravity for re-crushing.

[0028] When in use, the steel slag to be magnetically separated is put into the crushing cylinder 5 through the crushing port 7 for crushing. The extrusion cylinder 15 placed inside the crushing cylinder 5 is symmetrically arranged, and the crushing rods 17 on the side walls of the symmetrically arranged extrusion cylinder 15 are staggered. The extrusion cylinder 15 uses the staggered spacing between the crushing rods 17 to crush the steel slag entering the crushing cylinder 5. The controller 31 controls the hydraulic cylinder 20 to start, and the power end of the hydraulic cylinder 20 extends to push the sliding support 11 to slide along the inner wall of the U-shaped block 10. The sliding support 11 drives the extrusion cylinder 15 to move relative to each other through the driving shaft 13.

As the extrusion cylinder 15 slowly rotates, the slag block moves toward the straight line distance between the extrusion cylinders 15 and 15. At this time, the volume of the slag block is relatively large, and the extrusion cylinder 15 applies pressure to the sliding support 11 through the driving shaft 13.

The spacing between the extrusion cylinders 15 is increased, which is convenient for the steel slag blocks with greater hardness to pass through. The harder steel slag blocks fall into the upper wall of the partition wear-resistant plate 23 under the diversion of the convex arc plate 6; The controller 31 controls the adsorption electromagnet 25 to start, and the adsorption electromagnet 25 is energized to generate magnetism. The adsorption electromagnet 25 is fixed between the inner wall of the crushing cylinder 5 and the partition wear-resistant plate 23. The adsorption electromagnet 25 uses magnetic force to adsorb the extruded iron ball 30 through the magnetic suction port 24. The extruded iron ball 30 slides along the sliding groove 27 using the deformation of the lengthened spring 28, and the extension rod 29 slides out of the sliding groove 27. The extension rod 29 is extended and fits the side wall of the partition wear-resistant plate 23. The adjacent extension rod 29 picks up the uncrushed steel slag block placed on the upper wall of the partition wear-resistant plate 23 during the rotation process. The steel slag block extension rod 29 rotates to the position of the crushing cylinder 5 near the crushing port 7, and then the steel slag block falls into the extrusion cylinder 15 under the action of its own gravity for re-crushing, thereby completing the crushing operation of the steel slag under the condition of reducing the driving load of the drive motor 12, and the crushed steel slag is evenly sent to the magnetic separation area; the above operation can be repeated when used next time.

The steel slag iron flake crushing magnetic separator according to claim 8, characterized in that: The extension rod (29) is slidably arranged inside the sliding groove (27), the extrusion iron ball (30) is arranged on the side of the extension rod (29) away from the crushing rod (17), and the lengthening spring (28) is arranged between the extension rod (29) and the inner wall of the sliding groove (27), and the lengthening spring (28) is shortened.

10. The method for using the steel slag iron flake crushing magnetic separator according to claim 9, characterized in that: Step 1: The magnetically separated steel slag is placed into the crushing drum (5) through the crushing port (7) for crushing; Step 2: The driving motor (12) drives the driving shaft (13) to rotate through the power end, and the driving shaft (13) rotates through the extrusion cylinder (15). The symmetrically arranged extrusion cylinders (15) rotate clockwise and counterclockwise respectively. The extrusion cylinders (15) rotate relatively. The driving shaft (13) drives the crushing rod (17) through the dividing rod block (16) to extrude and crush the steel slag entering between the extrusion cylinder (15). Step 3: The pressure sensor (21) monitors the pressure inside the hydraulic cylinder (20) through the detection end, and the power end of the hydraulic cylinder (20) shortens to drive the sliding support (11) to slide along the U-shaped block (10), thereby increasing the distance between the extrusion cylinders (15); Step 4: The adsorption electromagnet (25) utilizes magnetic force to adsorb the extruded iron ball (30) through the magnetic suction port (24), and the extension rod (29) is extended to fit the side wall of the partition wear-resistant plate (23). The adjacent extension rod (29) picks up the unbroken steel slag block placed on the upper wall of the partition wear-resistant plate (23) during the rotation process.
