[0001] The present invention relates to the field of screening technology, in particular to a spherical particle separation method and a device thereof. Background Art

[0002] Mechanical screening is a relatively common screening method. It usually uses screening equipment such as rotary vibrating screens or linear vibrating screens. The material to be screened is placed above the screen surface, and then the vibration and rotation of the screen surface separates the particles according to their size, thereby achieving particle screening.

[0004] Therefore, a vibrating screen is often needed during screening to screen the material. When the ore is processed into powder, a ball mill is needed to grind the ore. The processed material contains both ore powder and steel balls. At this time, a vibrating screen is needed to screen the ore powder and steel balls, so that the spherical steel balls can be extracted from the ore powder. However, ore powder is often attached to the surface of the steel balls, and this part of the ore powder cannot be separated from the steel balls in time, which will eventually affect the efficient collection of the ore powder. Summary of the Invention

[0005] The purpose of the present invention is to provide a spherical particle separation method, which can be beneficial to separating the ore powder on the surface of the lower steel ball.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A method for separating spherical particles, comprising the following steps:

[0007] (1) Pour the mixture of ore powder and steel balls into the silo located above the feed end of the vibrating screen;

[0008] (2) Separate the steel balls and ore powder through a vibrating screen;

[0009] (3) Use the blowing assembly in the vibrating screen to spray the ore powder off the surface of the steel ball;

[0010] (4) Collect the separated steel balls and ore powder.

[0011] By adopting the above technical solution, the mixed material of ore powder and steel balls is poured into the silo, and then the steel balls and ore powder are separated by a vibrating screen, wherein the ore powder on the surface of the steel balls can be sprayed off by the blowing component, and then the separated steel balls and ore powder can be efficiently collected. At this time, the blowing component can be used to facilitate the separation of the ore powder on the surface of the steel balls.

[0012] The present invention also aims to provide a device for separating spherical particles, which can be beneficial for separating the ore powder on the surface of the lower steel ball.

[0013] The above technical objectives of the present invention are achieved through the following technical solutions: a device for a spherical particle separation method, comprising a silo, a vibrating screen located below the silo, the vibrating screen comprising a body extending obliquely downward, supporting legs arranged on the lower side of the body, a separation plate arranged on the upper side of the body and used to screen out steel balls, a lower slide plate arranged on the lower side of the body and for ore powder to fall, a first discharge trough arranged at the lower end of the body and at the height of the separation plate, a first collecting box arranged below the first discharge trough, a second discharge trough arranged at the lower end of the body and at the height of the lower slide plate, a second collecting box arranged below the second discharge trough, and a blowing assembly arranged on the upper side of the body and used to perform surface blowing on the falling steel balls.

[0014] By adopting the above technical solution, the mixed material of ore powder and steel balls falls into the material hopper and then falls onto the separation plate, through which the steel balls can be screened out, while the ore powder falls onto the sliding plate, wherein the steel balls falling on the separation plate can be used to blow the ore powder adhered to the surface of the steel balls through the blowing assembly, and the steel balls can be collected by the first collecting box after being discharged from the first discharge chute, while the ore powder can be collected by the second collecting box after being discharged from the second discharge chute, and finally the ore powder on the surface of the steel balls can be separated, which is conducive to the efficient collection of ore powder.

[0015] The present invention is further configured as follows: the blowing assembly includes a wrapping cover arranged on the machine body and located above the separation plate, multiple blowing pipes arranged on the wrapping cover, an air intake pipe for connecting the multiple blowing pipes, and a jet pump arranged outside the machine body and connected to the air intake pipe.

[0016] By adopting the above technical solution, the high-speed airflow generated by the jet pump enters the air inlet pipe and can be sent to each blowing pipe, and the high-speed airflow ejected from the blowing pipe can be used to blow on the surface of the steel ball passing below, thereby separating the ore powder on the surface of the lower steel ball.

[0017] The present invention is further configured as follows: a baffle located below the wrapping cover is provided in the machine body and between the separation plate and the lower slide plate.

[0018] By adopting the above technical solution, the baffle is set at a position between the separation plate and the lower slide plate, and the baffle is located below the wrapping cover. At this time, the baffle can block the airflow blowing downward from the separation plate, thereby reducing the airflow directly blowing on the surface of the lower slide plate, and ultimately avoiding the airflow affecting the downward movement of the ore powder on the lower slide plate.

[0019] The present invention is further configured as follows: the separation plate includes cross bars located at both ends of the body, and a plurality of screening rods arranged between the two cross bars and evenly spaced, and the spacing between two adjacent screening rods is smaller than the cross-sectional outer diameter of the steel ball.

[0020] By adopting the above technical solution, since the distance between two adjacent screening rods is smaller than the cross-sectional outer diameter of the steel ball, the steel ball can be embedded between the two adjacent screening rods after falling on the separation plate, so the steel ball can roll down along the screening rods.

[0021] The present invention is further configured as follows: a diversion assembly is also provided in the machine body for diverting the steel balls falling between multiple screening rods so that there is a distance between the steel balls. The diversion assembly includes a first connecting rod arranged in the machine body and located above the separation plate, a plurality of diversion plate groups arranged on the first connecting rod and evenly distributed along the first connecting rod, the diversion plate group includes two first plates respectively located on both sides of adjacent screening rods and inclined downward, and a second plate arranged at the side edge of the lower side of the first plate. A single steel ball is allowed to pass through between the two second plates in the diversion plate group.

[0022] By adopting the above technical solution, when multiple steel balls slide down between multiple screening rods at the same time, adjacent steel balls often stick together, and even multiple steel balls form a steel ball surface. At this time, the airflow sprayed toward the steel balls cannot pass through the screening rods smoothly. It is easy for the ore powder on the steel balls to bounce between the steel balls after being sprayed by the airflow and then fall back on the surface of the steel balls, which is not conducive to the blowing off of the ore powder on the surface of the steel balls.

[0023] The multi-group diverter plate group on the first connecting rod is utilized, and the first plate body in the diverter plate group can block the rolling steel balls. At the same time, the steel balls blocked by the first plate body can continue to roll along the second plate body after sliding down the first plate body. At this time, the multi-group diverter plate group can separate multiple steel balls into multiple paths, and there are gaps between the multiple steel balls, which can ultimately help the airflow sprayed toward the steel balls to pass through the screening rod smoothly, which is conducive to blowing off the ore powder on the surface of the steel balls.

[0024] The present invention is further configured as follows: a separation component is also provided in the machine body for separating the steel balls falling on the same screening rod so that there is a distance between the steel balls. The separation component includes two second connecting rods arranged in the machine body and located below the separation plate, a plurality of base plates arranged on the second connecting rods and corresponding to the falling positions of multiple steel balls respectively, a rotating shaft rotatably connected to the base plate at the lower end, four guide plates arranged at the upper end of the rotating shaft and evenly spaced along the circumference of the rotating shaft, and a positioning member arranged on the base plate and used to position the position of the rotating shaft after it is rotated 90 degrees.

[0025] By adopting the above technical solution, the positioning part is used to locate the position of the rotating shaft after it rotates 90 degrees, and each time the rotating shaft rotates 90 degrees, a steel ball can be allowed to roll down through the guide plate. At this time, a distance can be formed between multiple steel balls rolling down the same screening rod, so that a space for air flow to fall is formed around a single steel ball, which can ultimately help the air flow sprayed toward the steel balls to pass through the screening rod smoothly, and help to blow off the ore powder on the surface of the steel balls.

[0026] The present invention is further configured as follows: the positioning member includes a fixed plate arranged at the lower end of the rotating shaft, four card slots opened on the circumference of the fixed plate and evenly spaced along the circumference of the fixed plate, a swing arm hinged at one end to the base plate, a card block arranged at the end of the swing arm away from the base plate and used to be embedded in the card slot, a drive motor arranged on the base plate, a cam arranged on the output shaft of the drive motor and used to abut against the swing arm, and a return spring connected to the swing arm at one end and to the base plate at the other end.

[0027] By adopting the above technical solution, the driving motor is used to drive the cam to rotate. One rotation of the cam can push the swing arm to swing toward the side away from the fixed disk, so that the block is disengaged from the slot and the reset spring is compressed. Then, under the action of the steel ball's own gravity, the steel ball can push the guide plate, so that the rotating shaft and the guide plate rotate. When the slot is rotated to the position of the block again, the block can be embedded in the slot again under the elastic restoring force of the reset spring. At this time, the rotating shaft rotates 90 degrees, and finally the position of the rotating shaft after 90 degrees is positioned; and each rotation of the cam can drive a steel ball to fall, and at this time, a distance can be formed between multiple steel balls rolling down on the same screening rod.

[0028] The present invention is further configured as follows: an extension plate is provided at the end of the second plate body located in the diverter plate group and away from the rotating shaft.

[0029] By adopting the above technical solution, the extension plate is used to limit the steel ball at the position of the guide plate, so as to prevent the presence of the guide plate from affecting the stable rolling of the steel ball on the screening rod.

[0030] The present invention is further configured as follows: connecting columns are provided at both ends of the cross bar, a connecting sleeve for the connecting column to pass through is provided on the inner wall of the body, a vibration spring is provided on the connecting column, one end of which is connected to the cross bar and the other end is connected to the connecting sleeve, and a turntable is also provided at the upper end of the output shaft of the drive motor, and a vibration protrusion for contacting the screening rod is provided on one side of the upper surface of the turntable.

[0031] By adopting the above technical solution, when the drive motor drives the cam to rotate, the drive motor will also drive the turntable to rotate, and the turntable can be in contact with the screening rod through the vibrating protrusion, thereby driving the screening rod to rise. At this time, the vibration spring can be compressed, and after the screening rod passes over the vibrating protrusion, the screening rod falls back down under the elastic restoring force of the vibration spring. At this time, as the drive motor continues to drive the turntable to rotate, vibration can be generated on the separation plate, which is conducive to the efficient shaking off of the ore powder.

[0032] The beneficial effects of the present invention are as follows: after the mixed material of ore powder and steel balls falls into the hopper, it can fall on the separation plate, and the steel balls can be embedded between two adjacent screening rods and roll down, wherein the multi-group diverter plate group on the first connecting rod is utilized, and the first plate body in the diverter plate group can block the rolling steel balls, and at the same time, the steel balls blocked by the first plate body can continue to roll down along the second plate body after sliding down along the first plate body. At this time, the multi-group diverter plate group can separate the multiple steel balls into multiple lanes, and there are gaps between the multiple steel balls; at the same time, the driving motor is used to drive the cam to rotate, and the cam rotates one circle to push the pendulum The movable arm swings toward the side away from the fixed plate, so that the block comes out of the slot and the return spring is compressed. Then, under the action of the steel ball's own gravity, the steel ball can push the guide plate, so that the rotating shaft and the guide plate rotate. When the slot rotates to the position of the block again, the block can be embedded in the slot again under the elastic restoring force of the return spring. At this time, the rotating shaft rotates 90 degrees, and finally the position after the rotating shaft rotates 90 degrees can be positioned. Each rotation of the cam can drive a steel ball to fall, and at this time, a distance can be formed between the multiple steel balls rolling down on the same screening rod.

[0033] When a single steel ball rolls to the bottom of the spray assembly, the high-speed airflow generated by the jet pump enters the air inlet pipe and is then sent to each spray pipe. The high-speed airflow ejected from the spray pipe can spray the surface of the single steel ball passing below, thereby separating the ore powder on the surface of the lower steel ball. At this time, since a space for airflow to fall is formed around the single steel ball, it is conducive to the airflow sprayed toward the steel ball to pass through the screening rod smoothly, which is conducive to the blowing off of the ore powder on the surface of the steel ball.

[0034] At the same time, when the driving motor drives the cam to rotate, the driving motor also drives the turntable to rotate, and the turntable can be abutted against the screening rod through the vibrating protrusion, thereby driving the screening rod to lift upward. At this time, the vibration spring can be compressed, and after the screening rod passes the vibrating protrusion, the screening rod falls back downward under the elastic restoring force of the vibration spring. At this time, as the driving motor continues to drive the turntable to rotate, vibration can be generated on the separation plate, which is conducive to efficiently shaking off the ore powder.

[0035] Finally, the steel balls can be screened out through the separation plate, and the ore powder falls to the lower sliding plate. The steel balls can be collected by the first collecting box after being discharged from the first discharge chute. At the same time, the ore powder can be collected by the second collecting box after being discharged from the second discharge chute. Finally, the ore powder on the surface of the steel balls can be separated, which is conducive to the efficient collection of ore powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Reference Figure 3 、 Figure 5 、 Figure 6 、 Figure 7, wherein the positioning member 45 is provided on the base plate 42 and is used to position the position of the rotating shaft 43 after rotating 90 degrees. The positioning member 45 includes a fixed plate 451, a slot 452, a swing arm 453, a block 454, a drive motor 455, a cam 456 and a return spring 457. The fixed plate 451 is welded to the circumference of the lower end of the rotating shaft 43, and there are four slots 452 and they are opened on the circumference of the fixed plate 451, and the four slots 452 are evenly spaced along the circumference of the fixed plate 451; at the same time, one end of the swing arm 453 is hinged to the base plate 42, and the block 454 is welded to the end of the swing arm 453 away from the base plate 42 and It is used to be embedded in the slot 452, and the surfaces of the block 454 and the slot 452 are both arc-shaped; the driving motor 455 is fixed to the base plate 42 by bolts, and the cam 456 is fixed to the output shaft of the driving motor 455 by bolts, and the cam 456 can be used to abut against the swing arm 453, and at the same time, one end of the reset spring 457 is welded to the swing arm 453 and the other end is welded to the base plate 42; and the upper end of the output shaft of the driving motor 455 is also fixed with a turntable 4551 by bolts, and a vibration protrusion 4552 is integrally provided on one side of the upper surface of the turntable 4551, and the vibration protrusion 4552 can be used to abut against the screening rod 232.

[0057] Principle: After the mixed material of ore powder and steel balls falls into the hopper 1, it can fall onto the separation plate 23, and the steel balls can be embedded between the two adjacent screening rods 232 and roll down, wherein the multi-group diverter plate group 32 on the first connecting rod 31 is utilized, and the first plate body 321 in the diverter plate group 32 can block the rolling steel balls, and at the same time, the steel balls blocked by the first plate body 321 can slide down along the first plate body 321 and then continue to roll along the second plate body 322. At this time, the multi-group diverter plate group 32 can separate the multiple steel balls into multiple lanes, and there are gaps between the multiple steel balls; at the same time, the driving motor 455 is used to drive the cam 456 to rotate, and the cam 456 rotates one circle to push the swing arm 453 away One side of the fixed disk 451 swings, so that the block 454 disengages from the slot 452, and the return spring 457 is compressed. Then, under the action of the steel ball's own gravity, the steel ball can push the guide plate 44, so that the rotating shaft 43 and the guide plate 44 rotate. When the slot 452 rotates to the position of the block 454 again, under the elastic restoring force of the return spring 457, the block 454 can be embedded in the slot 452 again. At this time, the rotating shaft 43 rotates 90 degrees, and finally the position of the rotating shaft 43 after rotating 90 degrees can be positioned; and each rotation of the cam 456 can drive a steel ball to fall, and at this time, a distance can be formed between the multiple steel balls rolling down on the same screening rod 232.

[0058] When a single steel ball rolls to the bottom of the blowing assembly 29, the high-speed airflow generated by the jet pump 294 enters the air inlet pipe 293 and is then sent to each blowing pipe 292. The high-speed airflow ejected from the blowing pipe 292 can be used to blow the surface of the single steel ball passing below, thereby separating the ore powder on the surface of the lower steel ball. At this time, since space for the airflow to fall is formed around the single steel ball, the airflow sprayed toward the steel ball can smoothly pass through the screening rod 232, which is conducive to blowing off the ore powder on the surface of the steel ball.

[0059] At the same time, when the drive motor 455 drives the cam 456 to rotate, the drive motor 455 will also drive the turntable 4551 to rotate, and the turntable 4551 can be in contact with the screening rod 232 through the vibration protrusion 4552, thereby driving the screening rod 232 to rise upward. At this time, the vibration spring 52 can be compressed, and after the screening rod 232 passes over the vibration protrusion 4552, the screening rod 232 falls back downward under the elastic restoring force of the vibration spring 52. At this time, as the drive motor 455 continues to drive the turntable 4551 to rotate, vibration can be generated on the separation plate 23, which is conducive to efficiently shaking off the ore powder.

[0060] Finally, the steel balls can be screened out through the separation plate 23, and the ore powder falls onto the lower slide plate 24. The steel balls can be collected by the first collection box 26 after being discharged from the first discharge trough 25. At the same time, the ore powder can be collected by the second collection box 28 after being discharged from the second discharge trough 27. Finally, the ore powder on the surface of the lower steel balls can be separated, which is conducive to the efficient collection of ore powder.
