Description

Technical Field

[0001] The invention relates to the field related to zirconia bead processing, and in particular to a grading and screening device and method for zirconia bead processing. Background Art

[0002] Zirconia beads, also known as "TZP" zirconium beads, are made of micron and sub-nano zirconium oxide and yttrium oxide as raw materials. They are used for ultra-fine grinding and dispersion of materials that require "zero pollution" and high viscosity and high hardness.

[0003] In the processing and production of zirconium beads, it is necessary to screen out zirconium beads of different diameters and store them separately; After searching, a screening device for processing zirconium oxide beads was disclosed, with the announcement number: CN218554682U; The patent uses equidistant rods for screening. The disadvantage of this screening method is that it cannot process more zirconium beads at the same time. This powder screening is essentially to screen the zirconium beads through the gap between two rods. If too many zirconium beads are put into the device, the rod will bend to a certain extent under the gravity of the zirconium beads, which will cause the gap between the two rods to become larger, and then there will be a certain probability that the zirconium beads at the powder screen will be of different sizes. But inspired by this device, we can think of setting up a multi-layer screening structure, that is, different spacings between rods in multiple layers, to achieve multi-stage screening. This device does not have a corresponding collection structure, that is, a structure for collecting zirconium beads of different diameters. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] For example, see Figures 1 to 11, a grading and screening device for processing zirconium oxide beads, comprising two frames 1, the two frames 1 are fixed by a transverse plate, the frames 1 are equipped with a screening assembly for screening zirconium beads, and the screening assembly is connected to a driving assembly installed on the frames 1; A collecting box 3 fixed between the two frames 1, and the collecting box 3 is at the bottom of the screening assembly, a blocking plate 302 for blocking is slidably mounted at the bottom of the collecting box 3, and a discharge bucket 301 is also fixed at the bottom of the collecting box 3; A graded discharge assembly is installed on one side of the frame 1, and the graded discharge assembly also cooperates with the sub-screening assembly.

[0031] In an embodiment of the present invention, zirconium beads are added to the screening component during processing, and then the screening component is driven to work by the driving component, the zirconium beads are graded and screened by the drying component, and the screened zirconium beads are transported to the graded discharge component, and the zirconium beads of different diameters after screening are discharged at different outlets by the graded discharge component.

[0032] Embodiment 2 is distinguished from Embodiment 1 in that: the screening assembly comprises a No. 1 sorting drum 5 rotatably mounted on two motors 2, and the No. 1 sorting drum 5 is connected to the driving assembly; The first sorting barrel 5 is provided with a second sorting barrel 501, the second sorting barrel 501 is provided with a third sorting barrel 502, and the third sorting barrel 502 is provided with a fourth sorting barrel 503; A spiral conveying plate 504 is provided between the first and second sorting drums 501, between the second and third sorting drums 501, and between the third and fourth sorting drums 502 and 503, and the first, second, third, and fourth sorting drums 501, 502, 503 are fixed by the spiral conveying plate 504; The ends of the No. 1 sorting barrel 5, No. 2 sorting barrel 501, No. 3 sorting barrel 502 and No. 4 sorting barrel 503 facing the graded discharge assembly are all open, and the ends of the No. 1 sorting barrel 5, No. 2 sorting barrel 501 and No. 3 sorting barrel 502 away from the graded discharge assembly are blocked, so as to form a feed port 601 at the end of the No. 4 sorting barrel 503 away from the graded discharge assembly, and the feed port 601 is rotatably connected to the feed hopper 6 fixed on the motor 2, and the feed port 601 is communicated with the feed hopper 6; The first sorting barrel 5, the second sorting barrel 501, the third sorting barrel 502, and the fourth sorting barrel 503 are uniformly provided with sorting holes 505; A knocking assembly is also arranged on the outer side of the No. 1 sorting cylinder 5 .

[0033] In the embodiment of the present invention, when the driving assembly is working, the No. 1 sorting drum 5 is driven to rotate, and when the No. 1 sorting drum 5 rotates, the No. 2 sorting drum 501, the No. 3 sorting drum 502, and the No. 4 sorting drum 503 are driven to rotate synchronously through the spiral conveying plate 504; During processing, zirconium beads are put into the feed hopper 6, and under the guidance of the feed hopper 6, the zirconium beads enter the No. 4 sorting barrel 503, and the No. 4 sorting barrel 503 and the sorting hole 505 are rotated to drive the zirconium beads toward the graded discharge assembly. When the diameter of the zirconium beads in the No. 4 sorting barrel 503 is smaller than the sorting hole 505 on the No. 4 sorting barrel 503 during transportation, the zirconium beads will fall into the No. 3 sorting barrel 502, thereby realizing the sorting while transporting the zirconium beads; Similarly, the zirconium beads in the No. 3 sorting barrel 502, the No. 2 sorting barrel 501, and the No. 1 sorting barrel 5 will also be sorted and transported synchronously, and finally transported to the graded discharge assembly; The principle of conveying by the spiral conveying plate 504 is similar to that of the auger. Conveying by spiral rotation is a prior art and will not be elaborated here.

[0034] The sorting hole 505 of the first sorting barrel 5 has a larger aperture than that of the second sorting barrel 501 , the sorting hole 505 of the second sorting barrel 501 has a larger aperture than that of the third sorting barrel 502 , and the sorting hole 505 of the third sorting barrel 502 has a larger aperture than that of the fourth sorting barrel 503 .

[0035] In the embodiment of the present invention, when the diameter of the zircon beads is smaller than the aperture of the sorting hole 505 of the fourth sorting barrel 503 during sorting by the fourth sorting barrel 503, the zircon beads fall into the third sorting barrel 502, and when the diameter of the zircon beads in the third sorting barrel 502 is smaller than the aperture of the sorting hole 505 of the third sorting barrel 502, the zircon beads fall into the second sorting barrel 501, and when the diameter of the zircon beads in the second sorting barrel 501 is smaller than the aperture of the sorting hole 505 of the second sorting barrel 501, the zircon beads fall into the first sorting barrel 5, thereby performing graded screening on the zircon beads; Among them, when the diameter of the zirconium beads in the No. 1 sorting barrel 5 is smaller than the diameter of the sorting hole 505 of the No. 1 sorting barrel 5, they fall into the collecting box 3 and are stored in the collecting box 3. When the zirconium beads in the collecting box 3 need to be cleaned, the sealing plate 302 is manually pulled to make the zirconium beads in the collecting box 3 fall into the discharge bucket 301 through the opening set at the bottom of the collecting box 3. The zirconium beads are guided by the discharge bucket 301 to fall to the designated position for easy collection.

[0036] The knocking assembly includes a bracket 4 fixed on the collection box 3; The bracket 4 includes two fixing plates, which are respectively fixed on both sides of the collection box 3, and multiple U-shaped frames are equidistantly fixed on the two fixing plates. A No. 1 transmission rod 7 is rotatably installed on the multiple U-shaped frames, and the No. 1 transmission rod 7 is connected to the driving assembly through a transmission member; A transmission square plate 704 is slidably installed on the multiple U-shaped frames, and the transmission square plate 704 is perpendicular to the No. 1 sorting cylinder 5. A knocking piece 7011 is fixed on one end of the transmission square plate 704 facing the No. 1 sorting cylinder 5. A reciprocating piece is installed on the U-shaped frame, and the reciprocating piece is connected to the No. 1 transmission rod 7.

[0037] In the embodiment of the present invention, when the driving assembly is working, the first transmission rod 7 is driven to rotate through the transmission member, and when the first transmission rod 7 rotates, the reciprocating members on the multiple U-shaped frames are driven to work synchronously, and when the reciprocating members work, the multiple transmission square plates 704 are driven to perform upright reciprocating motion, so that the first sorting cylinder 5 is knocked by the knocking member 7011 when the transmission square plate 704 reciprocates; When the first sorting drum 5, the second sorting drum 501, the third sorting drum 502, and the fourth sorting drum 503 are used for sorting, there will be a phenomenon that the zircon beads are exactly aligned with the sorting holes 505. When the zircon beads are rotated for sorting, there will be a phenomenon that the zircon beads collide with each other, and then the zircon beads are "embedded" in the sorting holes 505. Although the embedding is not firm, they cannot fall naturally due to gravity, that is, the zircon beads cannot fall when they move to the highest point, and then the sorting holes 505 are blocked, resulting in a certain degree of reduction in sorting efficiency. The present invention knocks the first sorting cylinder 5 to make it vibrate to a certain extent, so that the zirconium beads inserted into the sorting holes 505 fall off. When knocking, the zirconium beads are at the highest point. The vibration during knocking and the gravity of the zirconium beads can easily separate the zirconium beads from the sorting holes 505. Among them, the knocking member 7011 in this embodiment is made of rubber material, so that the transmission square plate 704 will not cause the No. 1 sorting cylinder 5 to be dented when knocking the No. 1 sorting cylinder 5, because the knocking member 7011 will deform itself when colliding with the No. 1 sorting cylinder 5, and its principle is the same as that of a rubber hammer.

[0038] The transmission member includes a No. 2 transmission rod 701 rotatably mounted at the bottom of one of the brackets 4. The No. 2 transmission rod 701 is connected to the No. 1 transmission rod 7 via a No. 2 transmission chain 703. A No. 2 gear 702 is coaxially fixed to the end of the No. 2 transmission rod 701. The No. 2 gear 702 is connected to the driving assembly.

[0039] In the embodiment of the present invention, when the driving assembly is working, it drives the second gear 702 to rotate, so that when the second gear 702 rotates, the second transmission rod 701 drives the first transmission rod 7 to rotate through the second transmission chain 703, so that when the first transmission rod 7 rotates, multiple reciprocating parts are synchronously driven to work.

[0040] The reciprocating member includes a transmission shaft 709 rotatably mounted on the bracket 4, an incomplete gear 708 is coaxially fixed on the transmission shaft 709, and the incomplete gear 708 is connected to the first transmission rod 7 through a bevel gear set 7010; The transmission square plate 704 is provided with a rack 707 that matches the transmission square plate 704 on the side facing the incomplete gear 708; Guide rods 705 are fixed on the bracket 4 at both sides of the transmission square plate 704. The guide rods 705 are slidably connected to the transmission square plate 704. A spring 706 is sleeved on the guide rods 705. One end of the spring 706 is fixed to the transmission square plate 704 and the other end is fixed to the bracket 4.

[0041] In the embodiment of the present invention, when the first transmission rod 7 rotates, the bevel gear set 7010 drives the multiple transmission shafts 709 to rotate synchronously; When the transmission shaft 709 rotates, the incomplete gear 708 is driven to rotate. After the toothed portion of the incomplete gear 708 meshes with the rack 707, it continues to rotate to drive the rack 707 and the transmission square plate 704 to rise vertically. When the transmission square plate 704 rises vertically, the spring 706 is stretched to allow the spring 706 to store a certain amount of elastic potential energy. When the toothed portion of the incomplete gear 708 rotates to disengage from the rack 707, the elastic potential energy stored in the spring 706 is instantly released. By releasing the elastic potential energy of the spring 706, the transmission square plate 704 and the knocking member 7011 are driven to drop rapidly instantly, and the knocking member 7011 knocks the first sorting cylinder 5; Among them, since the No. 1 sorting cylinder 5, the No. 2 sorting cylinder 501, the No. 3 sorting cylinder 502, and the No. 4 sorting cylinder 503 are connected by the spiral conveying plate 504, when the No. 1 sorting cylinder 5 is struck to generate vibration, the vibration will be transmitted to the No. 2 sorting cylinder 501, the No. 3 sorting cylinder 502, and the No. 4 sorting cylinder 503 through the spiral conveying plate 504; As the diameter of the zirconium beads increases towards the inside, the corresponding weight will also be greater, and the vibration force required to make them fall when vibrated will be smaller, so the phenomenon of insufficient vibration force will not occur.

[0042] Embodiment 3 is distinguished from Embodiment 1 or / and Embodiment 2 in that: the graded discharge group comprises a No. 1 discharge pipe 8, a No. 2 discharge pipe 801, a No. 3 discharge pipe 802, and a No. 4 discharge pipe 803 which are sequentially sleeved, and the No. 1 discharge pipe 8 is fixed to the frame 1; The first discharge pipe 8, the second discharge pipe 801, the third discharge pipe 802, and the fourth discharge pipe 803 are connected by a fixing plate; see Figure 7 , its connection position is in the direction of the entrance; The No. 1 discharge pipe 8 is rotatably connected to the No. 1 sorting barrel 5, the No. 2 discharge pipe 801 is rotatably connected to the No. 2 sorting barrel 501, the No. 3 discharge pipe 802 is rotatably connected to the No. 3 sorting barrel 502, and the No. 4 discharge pipe 803 is rotatably connected to the No. 4 sorting barrel 503, and the connection positions are all at the open ends of the No. 1 sorting barrel 5, the No. 2 sorting barrel 501, the No. 3 sorting barrel 502, and the No. 4 sorting barrel 503; The first discharge pipe 8, the second discharge pipe 801, the third discharge pipe 802, and the fourth discharge pipe 803 are all arranged in an L shape, with the horizontal part being the X-axis and the vertical part being the Y-axis. The first discharge pipe 8, the second discharge pipe 801, the third discharge pipe 802, and the fourth discharge pipe 803 are all fixed with a discharge square pipe 804 connected thereto at the bottom of the X-axis; Among them, the X-axis length of the No. 2 discharge pipe 801 is greater than that of the No. 1 discharge pipe 8, the X-axis length of the No. 2 discharge pipe 801 is greater than that of the No. 3 discharge pipe 802, and the X-axis length of the No. 4 discharge pipe 803 is greater than that of the No. 3 discharge pipe 802.

[0043] In the embodiment of the present invention, since the No. 1 discharge pipe 8, the No. 2 discharge pipe 801, the No. 3 discharge pipe 802, and the No. 4 discharge pipe 803 are fixed by a fixing plate, they can also be regarded as a whole, that is, the No. 2 discharge pipe 801, the No. 3 discharge pipe 802, and the No. 4 discharge pipe 803 in the No. 1 discharge pipe 8 will not move when the zirconium beads are transported; The zirconium beads transported to the end by the No. 1 sorting cylinder 5 will enter the No. 1 discharge pipe 8. Similarly, the No. 2 sorting cylinder 501 corresponds to the No. 2 discharge pipe 801, the No. 3 sorting cylinder 502 corresponds to the No. 3 discharge pipe 802, and the No. 4 sorting cylinder 503 corresponds to the No. 4 discharge pipe 803. After the zirconium beads enter the No. 1 discharge pipe 8, the actual zirconium beads are located between the outer wall of the No. 2 discharge pipe 801 and the inner wall of the No. 1 discharge pipe 8, so that a plurality of different zirconium beads are separated and will not be mixed. Under the guidance of the No. 1 discharge pipe 8, when the zirconium beads move to the end, they are discharged through the discharge square pipe 804; Since the lengths of discharge pipe No. 1 8, discharge pipe No. 2 801, discharge pipe No. 3 802 and discharge pipe No. 4 803 in the X-axis direction are different, the discharge square tubes 804 are arranged equidistantly, that is, there are four different discharge square tubes 804, and the discharged zirconium beads are arranged from large to small.

[0044] The first discharge pipe 8, the second discharge pipe 801, the third discharge pipe 802, and the fourth discharge pipe 803 are all arranged at an angle; Among them, the tilting is set to the X-axis position of the No. 2 discharge pipe 801, the No. 3 discharge pipe 802, and the No. 4 discharge pipe 803, and the Y-axis and X-axis of the No. 1 discharge pipe 8 are tilted toward the low position through the tilting.

[0045] In the embodiment of the present invention, the principles of the No. 1 discharge pipe 8, the No. 2 discharge pipe 801, the No. 3 discharge pipe 802, and the No. 4 discharge pipe 803 are the same, and the description is made here with respect to the No. 1 discharge pipe 8; By inclining, the Y axis and X axis of the No. 1 discharge pipe 8 form inclined planes. Compared with the Y and X axis of the No. 1 discharge pipe 8 being horizontal, the inclined plane assists the passage of the zirconium beads during transportation, thereby avoiding the accumulation of the zirconium beads.

[0046] The driving assembly includes a motor 2 fixed on the frame 1, a No. 1 gear 201 is rotatably mounted on the frame 1, the No. 1 gear 201 is connected to the output shaft of the motor 2 via a No. 1 transmission chain 203, a gear ring 202 is coaxially fixed to the end of the No. 1 sorting barrel 5, and the gear ring 202 is meshed with the No. 1 gear 201; The second gear 702 is meshed with the gear ring 202 .

[0047] In the embodiment of the present invention, when the motor 2 is working, its output shaft drives the No. 1 gear 201 to rotate through the No. 1 transmission chain 203. When the No. 1 gear 201 rotates, it drives the gear ring 202 to rotate by meshing with the gear ring 202, and at the same time, the gear ring 202 is decelerated and the torque is increased.
