Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corundum crushing, in particular to a white corundum post-sintering crushing device and a use method thereof. BACKGROUND

[0002] White corundum, as a high-hardness abrasive, has high hardness and dense structure after sintering, and needs to be processed into a particle size meeting the subsequent use requirements by a crushing device. The existing white corundum post-sintering crushing device mostly adopts a single impact crushing structure, and has the following problems in actual application:

[0003] The clamping of the clinker is easy, and the crushing continuity is poor: the feed inlet or crushing channel of the existing device is mostly a fixed structure, and the white corundum clinker is easy to be clamped in the channel due to improper posture during the crushing process, resulting in device shutdown and cleaning, which seriously affects the crushing efficiency; and there is no mechanism to actively adjust the posture of the clinker, and the crushing interruption problem caused by the clamping of the clinker cannot be solved.

[0004] The crushing capacity of high-hardness clinker is insufficient: the existing device only relies on single impact force to achieve crushing, and for white corundum clinker with high hardness, single impact cannot meet the crushing requirements, and the clinker is easy to be clamped in the crushing cavity after impact, which needs manual intervention to continue crushing, and the application range is limited.

[0005] The crushing is insufficient, and the uniformity of the finished product is poor: the clinker in the existing device is mostly single-pass crushing, and the uncrushed clinker is difficult to enter the crushing process again, resulting in a high proportion of coarse material in the finished product; at the same time, there is no clinker position changing mechanism, and the stress angle of the clinker is single, which is easy to cause the problem of uneven crushing particle size, affecting the subsequent processing quality.

[0006] In view of this, a white corundum post-sintering crushing device and a use method thereof are provided. SUMMARY

[0007] The present application aims to provide a white corundum post-sintering crushing device and a use method thereof to solve the problems of clinker clamping, insufficient crushing capacity of high-hardness clinker, and insufficient crushing. To achieve the above purpose, the present application provides the following technical scheme: a white corundum post-sintering crushing device, comprising an outer shell provided with two inlets at the top, and two rollers rotatingly arranged in the outer shell, a motor driving the rotation of the rollers being arranged at the bottom of the outer shell, and a through hole allowing the partial leakage of white corundum clinker being formed in the side surface of the outer shell, the two rollers rotating in the same direction to crush the leaked clinker by mutual impact;

[0008] The inside of the roller is movably inserted with two blocking rods corresponding to the through opening, and the two blocking rods are arranged on the two sides of the through opening, the top of the roller is provided with a track, and a centrifugal frame is slidably arranged on the track and limited by a spring, the top end of the blocking rod is provided with an inclined groove, and the inclined grooves on the two blocking rods are oppositely arranged, when the centrifugal frame is displaced along the centrifugal force, the two ends of the centrifugal frame push the two blocking rods to move up and down along the inclined grooves.

[0009] Preferably, the bottom end of the roller is fixedly provided with a convex disc, and the rotating shaft of the motor is fixedly provided with a concave disc, and the concave disc and the convex disc are sleeved with each other.

[0010] The interfacing surface of the concave disc and the convex disc is provided with a roller groove, and a tapered roller is arranged in the roller groove, the diameters of the tapered rollers under the two rollers are different, and when the rotation of the roller is retarded, the upper and lower parts of the roller groove are misaligned and the roller is lifted up by the tapered roller.

[0011] Preferably, the blocking rod is composed of two rods arranged in an up-down manner, and a C-shaped structure return lever is arranged between the two rods, both ends of the return lever are provided with a sleeve, the end portions of the two rods are provided with a bolt inserted into the sleeve, and the bolt and the sleeve are provided with threads matched with each other, and when the sleeve moves up, the return lever is rotated back into the roller from the through opening through the threads.

[0012] Preferably, the side of the blocking rod close to the through opening is fixedly provided with a rubber buffer layer, and the thickness of the rubber buffer layer is 2-5mm.

[0013] Preferably, the inner wall of the track is provided with a lubricating groove, the lubricating groove is filled with solid lubricating grease, and the length of the lubricating groove is matched with the sliding stroke of the centrifugal frame.

[0014] Preferably, the inner wall of the roller groove of the convex disc is provided with a wear-resistant coating, and the wear-resistant coating is a tungsten carbide coating.

[0015] Preferably, the end of the return lever away from the sleeve is provided with an arc-shaped pushing part, and the curvature radius of the arc-shaped pushing part is consistent with the curvature radius of the inner wall of the roller.

[0016] A method for using a white corundum breaking device after sintering, comprising the following steps:

[0017] S1, through the two inlets on the top of the shell, white corundum clinker is uniformly and equally fed into the two rollers, and the control single feeding amount is not more than 1 / 3 of the volume of the roller, so as to ensure that the centrifugal force can stably throw the clinker to the through opening of the shell and preliminarily clamp it, laying a foundation for the subsequent precise butt impact and breaking of the clinker pushed by the two rollers.

[0018] S2, turn on the power of the motor to drive the two rollers to rotate at a uniform speed in the same direction, and in the process, the following actions are triggered synchronously:

[0019] The centrifugal force generated by the rotation of the drum drives the internal centrifugal frame to slide along the track, and the two ends are respectively embedded in the reverse inclined grooves of the two side stop rods, and synchronously push one side stop rod up and the other side stop rod down with displacement.

[0020] The dislocation movement of the stop rod directly drives the deflection angle of the clamped frit at the through port, which not only solves the problem of frit jamming and cannot smoothly leak out, but also adjusts the optimal stress posture for subsequent secondary impact.

[0021] S3, when the hardness of the frit is high and the first impact does not break, causing the rotation of the drum to be stalled, the differential mechanism is automatically triggered:

[0022] The recessed disc on the motor shaft and the convex disc at the bottom end of the drum produce relative displacement due to load difference, and the roller groove on the butt joint surface follows the displacement;

[0023] The dislocated roller groove extrudes the internal conical roller (the conical rollers on the two sides of the drum have different diameters), pushes the drum upwards, and makes the two sides of the drum have a speed difference and a height difference;

[0024] The drum under differential state exerts shear force on the frits in the up-down direction, and at the same time promotes the dislocation and separation of the jammed frits, which removes the jamming and creates conditions for the next round of impact and fragmentation.

[0025] S4, when the conical roller drives the drum to move up and down, the stop rod (composed of two rods) synchronously rises and falls with the inertia of the drum, driving the return lever linkage:

[0026] The sleeves at both ends of the return lever slide up and down along the pins at the end of the stop rod, and the threaded cooperation between the sleeves and the pins drives the return lever to rotate towards the inside of the drum;

[0027] The rotating return lever can actively push the unbroken frits in the through port into the inside of the drum, so that the frits realize multiple position switching in the drum, ensuring that they can be continuously impacted until the fragmentation requirement is met.

[0028] Compared with the prior art, the beneficial effects of the present application are:

[0029] In the present application, based on the principle of "centrifugal force throwing material + stop rod - centrifugal frame angle adjustment", when the motor drives the drum to rotate, the centrifugal force can stably throw the frits to the through port and preliminarily position them by the stop rod, at the same time, the centrifugal frame displaces with the centrifugal force, and the two side stop rods are pushed up and down by the inclined groove, driving the frits to deflect; when the drum slows down, the stop rod resets and can pull the frits to rotate, through multiple angle adjustments, the problem of frits being jammed in the through port due to improper posture is completely solved, ensuring that the frits continuously and smoothly leak out, avoiding the interruption of fragmentation caused by the blockage of the through port, and significantly improving the running continuity of the equipment.

[0030] In the application, according to the principle of “conical roller differential speed lifting + shear force auxiliary”, the conical roller realizes the flexible connection of the motor and the roller, when the hardness of the clinker is high and the roller is stalled due to the impact without breaking, the conical roller can be turned out from the convex disc and lift the roller, and then switch to the next roller groove to re-connect, so that the two side rollers form differential speed upward movement; both the upward and downward shear force supplements the single impact breaking force, and the jammed clinker is dislocated and separated upward and downward, the blockage is quickly removed and enters the next round of impact, greatly improving the processing capacity of the equipment for high hardness and difficult to break clinker, and widening the range of suitable materials.

[0031] In the application, according to the principle of “rebound lever transposition + multiple cycle impact”, when the conical roller drives the roller to move up and down, the inertia drives the rebound lever to slide up and down along the pin, and the rotation is realized through the threaded cooperation, so as to push the clinker in the through hole back to the inside of the roller; the clinker is no longer limited to single impact, but is repeatedly impacted by switching position in the roller, so as to ensure that each clinker can be broken to the target state, effectively avoiding the residual of coarse material caused by insufficient impact, and improving the uniformity and stability of the broken product.

[0053] A use method of a white corundum sintering and breaking equipment, comprising the following steps:

[0054] S1, through the two inlets on the top of the shell 1, the white corundum clinker is uniformly and equally put into the two side drums 2, the single feeding amount is controlled to be not more than 1 / 3 of the volume of the drum 2, and the centrifugal force can stably throw the clinker to the opening 4 of the shell 1 and preliminarily clamp it when the drum 2 rotates, thereby laying a foundation for the subsequent precise butt joint and impact breaking of the clinker pushed by the two side drums 2.

[0055] S2, the power supply of the motor 3 is turned on, and the two drums 2 are driven to rotate at a uniform speed in the same direction, and the following actions are triggered synchronously in the process:

[0056] The centrifugal force generated by the rotation of the drum 2 drives the internal centrifugal frame 8 to slide along the track 6, and the two ends of the internal centrifugal frame 8 are respectively embedded in the reverse inclined grooves 9 of the two side blocking rods 5, and the internal centrifugal frame 8 synchronously pushes one side blocking rod 5 to move upward and the other side blocking rod 5 to move downward with the displacement.

[0057] The dislocation movement of the blocking rod 5 directly drives the deflection angle of the clinker clamped at the opening 4, which solves the problem that the clinker cannot be smoothly leaked and adjusts the optimal stress state for the subsequent second impact.

[0058] S3, when the hardness of the clinker is high and the drum 2 rotation is stalled due to the first impact without breaking, the differential mechanism is automatically triggered:

[0059] The concave disc 11 on the rotating shaft of the motor 3 and the convex disc 10 at the bottom end of the drum 2 produce relative displacement due to the load difference, and the roller grooves 12 on the butt joint surface of the two are dislocated upward and downward.

[0060] The dislocated roller grooves 12 extrude the internal conical rollers 13, and the conical rollers 13 matched with the two side drums 2 have different diameters, which push the drum 2 to move upward, so that the two side drums 2 form a speed difference and a height difference.

[0061] The drum 2 in the differential state applies shear force to the clinker on both sides in the upward and downward directions, and at the same time promotes the clinker to be dislocated and separated upward and downward, thereby removing the clinker and creating conditions for the next round of impact breaking.

[0063] The sleeve 15 at both ends of the back rod 14 slides up and down along the pin 16 at the end of the blocking rod 5, and the sleeve 15 cooperates with the thread 17 of the pin 16 to drive the back rod 14 to rotate to the inside of the drum 2.

[0064] The rotating back rod 14 can actively push the unbroken clinker in the through hole 4 into the inside of the drum 2, so that the clinker realizes multiple position switching in the drum 2, and ensures that it can be continuously impacted until the crushing requirement is met.
