Technical Field

[0001] This application relates to the technical field of mechanical screening equipment, and particularly relates to a multifunctional diamond particle screening device. Background Art

[0002] The screening of diamond particles is a key process in the field of material processing. Traditional screening equipment usually adopts a combined design of a spiral guiding plate with a fixed structure and a screen mesh. The material is driven to move through vibration or centrifugal force, and particle classification is achieved by using the difference in the aperture of the screen mesh. However, the content of tiny particles in diamond raw materials varies significantly from batch to batch. When the content of tiny particles in the raw material is low, the spiral guiding plate with a fixed length may cause the particles to stay on the screen for too long, reducing the processing efficiency. Summary of the Invention

[0003] In order to overcome the disadvantages that the content of tiny particles in diamond raw materials varies significantly from batch to batch, and when the content of tiny particles in the raw material is low, the spiral guiding plate with a fixed length may cause the particles to stay on the screen for too long, reducing the processing efficiency, the present invention provides a multifunctional diamond particle screening device.

[0004] Technical Solution: A multifunctional diamond particle screening device includes a vibrator, a bottom frame, an upper frame, and a screen mesh. The vibrator is connected to the bottom frame; the upper part of the bottom frame is fixedly connected to the upper frame; the screen mesh is detachably connected inside the upper frame; it further includes an arc-shaped guiding plate. A number of arc-shaped guiding plates for ensuring the screening effect and efficiency are arranged on the screen mesh, and all the arc-shaped guiding plates together form a spiral guiding plate; adjacent two arc-shaped guiding plates are slidably connected; the outermost arc-shaped guiding plate is slidably connected to the upper frame.

[0005] As an improvement of the above solution, it further includes a dust-proof cover; the dust-proof cover is detachably connected to the upper frame; a feeding hole is opened in the middle of the dust-proof cover, and the feeding hole is directly opposite to the center of the screen mesh.

[0006] As an improvement of the above solution, a handle is arranged on the dust-proof cover.

[0007] As an improvement of the above solution, it further includes a limiting rod; a number of limiting rods are fixedly connected to the dust-proof cover; a number of jacks are respectively opened on each arc-shaped guiding plate; each limiting rod corresponds to one jack respectively.

[0008] As an improvement of the above solution, the lower part of the limiting rod is conical.

[0009] As an improvement of the above solution, it further includes a flexible strip; a number of flexible strips are annularly and equidistantly fixedly connected to the limiting rods in the middle area of the dust-proof cover; only the lower part of the flexible strip is fixedly connected to the limiting rod.

[0010] As an improvement of the above solution, a groove is respectively opened at the lower part of each flexible strip.

[0011] As an improvement of the above solution, two limiting plates are connected to the inner wall of the upper frame, and there is a gap between the lower side of the limiting plate and the screen; a through groove is opened at the lower part of the arc-shaped guide plate located at the outer edge of the screen; each limiting plate corresponds to a through groove respectively.

[0012] As an improvement of the above solution, the limiting plate is detachably connected to the upper frame, and a plurality of bolt mounting holes are opened on the vertical axis at the connection between the upper frame and the limiting plate.

[0013] As an improvement of the above solution, an inclined angle is opened on the lower surface of the through groove.

[0014] Beneficial effects: 1. In the present invention, some diamond particles are first put on the screen by an external feeding device for screening. Workers judge the content of fine particles in the diamond particles by observing the amount of particles discharged from the discharge port of the upper frame and the amount of particles discharged from the discharge port of the bottom frame. When the content of fine particles is small, the arc-shaped guide plate in the middle of the screen is first removed, and then the diamond particles are screened comprehensively. In this way, the moving path of the diamond particles is shortened, the screening and discharging of the diamond particles are accelerated, and the screening speed is improved.

[0015] 2. After the arc-shaped guide plate in the middle of the screen is removed in the present invention, the flexible strip on the corresponding limiting rod is no longer restricted by the arc-shaped guide plate. Therefore, the upper part of the flexible strip bends downward from the groove at the lower part of the flexible strip due to the action of gravity, so that the flexible strip abuts against the screen. When the screen vibrates, the scattered flexible strips block the diamond particles moving towards the outer edge of the screen, so that the retention time of the diamond particles in the middle of the screen is lengthened, the utilization rate of the screening area in the middle of the screen is improved, and the diamond particles are prevented from quickly transferring from the middle of the screen to the outer edge of the screen, reducing the filtration amount at the outer edge of the screen and improving the screening effect on the diamond particles.

[0016] 3. In the present invention, by arranging limiting plates on the inner wall of the upper frame and having a gap between the limiting plates and the screen, when the diamond particle layer passes through the limiting plates, the diamond particles higher than the gap are blocked by the limiting plates, restricting the diamond particle layer and avoiding the problem that the fine diamond particles in the diamond particle layer cannot be effectively screened due to the too thick diamond particle layer.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: A multi-functional diamond particle screening device, as Figures 1 - 7 shown, includes a vibrating machine 1, a bottom frame 2, an upper frame 3 and a screen 4; the vibrating machine 1 is connected to the bottom frame 2; the upper part of the bottom frame 2 is fixedly connected to the upper frame 3; the screen 4 is detachably connected within the upper frame 3; It further includes an arc-shaped guide plate 5; four arc-shaped guide plates 5 are arranged on the screen 4, and all the arc-shaped guide plates 5 together form a spiral guide plate; adjacent two arc-shaped guide plates 5 are slidably connected; the outermost arc-shaped guide plate 5 is slidably connected to the upper frame 3.

[0021] It further includes a dust-proof cover 21; the dust-proof cover 21 is detachably connected to the upper frame 3; a feeding hole is opened in the middle of the dust-proof cover 21, and the feeding hole is directly opposite to the center of the screen 4.

[0022] In order to facilitate holding the dust-proof cover 21, a handle is provided on the dust-proof cover 21.

[0023] It further includes a limiting rod 23; several limiting rods 23 are welded on the dust-proof cover 21; several jacks 501 are respectively opened on each arc-shaped guide plate 5; each limiting rod 23 corresponds to one jack 501 respectively.

[0024] In order to facilitate the insertion of the limiting rod 23 into the jack 501, the lower part of the limiting rod 23 is set to be conical.

[0025] Before using the vibrating machine 1, collectors are placed below the discharge openings of the bottom frame 2 and the upper frame 3 in advance. During use, an external feeding device is used to continuously drop diamond particles onto the middle of the sieve mesh 4, and the vibrating machine 1 is controlled to drive the bottom frame 2, the upper frame 3, and the sieve mesh 4 to vibrate. The material is under the combined action of centrifugal force and vibration in the sieve box, generating a throwing motion. The diamond particles larger than the sieve holes of the sieve mesh 4 are intercepted on the sieve mesh 4 and finally discharged from the discharge opening of the upper frame 3 and fall into the collector for collection. The diamond particles smaller than the sieve holes of the sieve mesh 4 pass through the sieve mesh 4 and fall into the bottom frame 2, and finally are discharged from the discharge opening of the bottom frame 2 and fall into the collector for collection, thus realizing the screening of diamond particles; a spiral guide plate formed by splicing a number of arc-shaped guide plates 5 is arranged on the sieve mesh 4. In this way, the external feeding device will continuously drop diamond particles onto the center of the spiral guide plate, and then under the guiding action of the spiral guide plate, the diamond particles move along a spiral trajectory, extending the residence time of the diamond particles on the sieve mesh 4 and ensuring full screening.

[0026] Since the content of fine particles in different batches of diamond particle raw materials is different, for the content of fine particles in different batches of diamond particles, the screening efficiency can be improved by adjusting the length of the spiral guide plate. Specifically: the external feeding device first puts some diamond particles onto the sieve mesh 4 for screening. Workers judge the content of fine particles in the diamond particles by observing the amount of particles discharged from the discharge opening of the upper frame 3 and the amount of particles discharged from the discharge opening of the bottom frame 2. When the content of fine particles is small, first remove the arc-shaped guide plate 5 in the middle of the sieve mesh 4, and then screen the diamond particles comprehensively. In this way, the moving path of the diamond particles is shortened, the screening and discharging of the diamond particles are accelerated, and the screening speed is increased.

[0027] Before screening, the dust cover 21 is installed on the upper frame 3. The diamond particle raw material falls onto the middle of the sieve mesh 4 through the feeding hole in the middle of the dust cover 21. The dust generated during the vibrating and screening process is blocked by the dust cover 21, preventing the dust from spreading and polluting the environment.

[0028] The adjacent two arc-shaped guide plates 5 are slidably connected to each other, and the outermost arc-shaped guide plate 5 is slidably connected to the upper frame 3. During the vibration screening, relative movement exists between the adjacent two arc-shaped guide plates 5 and between the outermost arc-shaped guide plate 5 and the upper frame 3, causing the arc-shaped guide plate 5 to separate from the screen mesh 4 and generating a gap, resulting in some diamond particles quickly discharging from the discharge port of the upper frame 3, affecting the screening. Therefore, a limiting rod 23 is welded on the dust cover 21. When the dust cover 21 is installed on the upper frame 3, the limiting rod 23 just inserts into the jack 501 on the arc-shaped guide plate 5. In this way, the arc-shaped guide plate 5 is restricted by the limiting rod 23 to prevent relative movement between the adjacent two arc-shaped guide plates 5 and between the outermost arc-shaped guide plate 5 and the upper frame 3 during the vibration screening, avoiding affecting the screening.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, it further includes a flexible strip 31; a plurality of flexible strips 31 are annularly and equidistantly fixedly connected to the limiting rod 23 in the middle area of the dust cover 21; only the lower part of the flexible strip 31 is fixedly connected to the limiting rod 23.

[0030] In order to facilitate the flexible strip 31 to be bent from the root, a groove 3101 is respectively opened at the lower part of each flexible strip 31.

[0031] It further includes a limiting plate 22; two limiting plates 22 are connected to the inner wall of the upper frame 3, and there is a gap between the lower side of the limiting plate 22 and the screen mesh 4; a through groove 502 is opened at the lower part of the arc-shaped guide plate 5 located at the outer edge of the screen mesh 4; each limiting plate 22 corresponds to a through groove 502 respectively.

[0032] In order to adjust the height of the limiting plate 22 to meet different user requirements, the limiting plate 22 is detachably connected to the upper frame 3, and a plurality of bolt mounting holes are opened on the vertical axis at the connection between the upper frame 3 and the limiting plate 22.

[0033] In order to facilitate the diamond particles to pass through the through groove 502, an inclined angle is opened on the lower surface of the through groove 502.

[0034] When screening diamond particles with a small content of fine particles, the arc-shaped guide plate 5 in the middle of the screen mesh 4 is removed. As a result, after the diamond particles fall into the middle of the screen mesh 4, due to the lack of restriction, the diamond particles will quickly move towards the outer edge of the screen mesh 4, resulting in a reduced utilization rate of the effective screening area in the middle of the screen mesh 4. Most of the diamond particles are screened from the outer edge of the screen mesh 4, resulting in a large filtration volume at the outer edge of the screen mesh 4, which is prone to overload, and further resulting in the diamond particles being discharged without being fully screened. Therefore, a number of flexible strips 31 are fixedly connected annularly and equidistantly at the lower part of the limiting rod 23. In the initial state, the flexible strips 31 at the lower part of the limiting rod 23 are located in the jacks 501 and the flexible strips 31 are restricted. After removing the arc-shaped guide plate 5 in the middle of the screen mesh 4, the flexible strips 31 on the corresponding limiting rod 23 are no longer restricted by the arc-shaped guide plate 5. Thus, the upper part of the flexible strip 31 bends downward from the groove 3101 at the lower part of the flexible strip 31 due to the action of gravity, so that the flexible strip 31 abuts against the screen mesh 4. During the vibration screening, the scattered flexible strips 31 block the diamond particles moving towards the outer edge of the screen mesh 4, increasing the residence time of the diamond particles in the middle of the screen mesh 4, improving the utilization rate of the screening area in the middle of the screen mesh 4, and preventing the diamond particles from quickly transferring from the middle of the screen mesh 4 to the outer edge of the screen mesh 4, reducing the filtration volume at the outer edge of the screen mesh 4 and improving the screening effect on the diamond particles.

[0035] Although the diamond particles moving towards the outer edge of the sieve 4 are blocked by the scattered flexible strips 31, the rapid transfer of diamond particles from the middle of the sieve 4 to the outer edge of the sieve 4 can be avoided, and the screening effect of diamond particles can be improved. However, as the screening progresses, during the process of the diamond particles flowing along the outer edge of the sieve 4 and discharging from the discharge port of the upper frame 3, affected by the vibration during the screening process, the diamond particles will gather at the outer edge of the sieve 4, forming a relatively thick layer of diamond particles, resulting in ineffective screening of the fine diamond particles in the diamond particle layer and insufficient screening of diamond particles. Therefore, a limiting plate 22 is provided on the inner wall of the upper frame 3. There is a gap between the limiting plate 22 and the sieve 4, and the gap is 1 cm. When the diamond particle layer passes through the limiting plate 22, the diamond particles higher than the gap are blocked by the limiting plate 22, restricting the diamond particle layer to prevent the diamond particle layer from being too thick and causing the problem of ineffective screening of the fine diamond particles in the diamond particle layer. Moreover, when the diamond particles are blocked by the limiting plate 22, some diamond particles are guided into the through groove 502, causing some diamond particles to move to the inside of the arc-shaped guide plate 5 and move along the outer edge of the sieve 4 again for screening once more, to conduct sufficient screening, ensure the screening effect, and by guiding some diamond particles to the inside of the arc-shaped guide plate 5, a large accumulation of diamond particles on the side of the limiting plate 22 can be avoided. The diamond particles passing through the limiting plate 22 move in a state with a thickness of 1 cm, and accumulation will still occur during the movement, thus affecting the sieving. Therefore, two limiting plates 22 are provided on the inner wall of the upper frame 3 to limit the thickness of the diamond particles multiple times to ensure the screening effect.

[0036] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
