Description

Technical Field

[0001] This utility model relates to the field of particle conveying equipment technology, and in particular to a monodisperse feeding device for fine sorting of particle sphericity. Background Technology

[0002] Particles are a common form of material in industry and are the only form in which most substances exist, except for water and air. In industrial production, there are often processes that involve moving particles from one location to another, which are called particle transport processes. Common methods include belt conveyors or vibratory conveyors.

[0003] The preparation of dispersed nuclear fuel requires the dispersion of a large number of fuel particles into a matrix. In a nuclear reactor, these fuel particles function to confine the radioactivity of fission gases, and their sphericity is subject to strict requirements. One crucial step in the fuel particle preparation process is the sorting out of non-spherical particles, which are then recycled as defective products. This step is critical to the performance of dispersed nuclear fuel particles, and the sphericity sorting of individual fuel particles is a key process frequently encountered in the particle manufacturing industry.

[0004] Currently, the technologies proposed in the research process for particle sphericity sorting include patents ZL2020102991057, ZL2020103007205, and ZL2014200557932. However, these patents all rely on one condition: during the particle feeding process, the particles need to be fed in a monodisperse manner. That is, the particles should avoid contact and collision with each other as much as possible when they enter the sorting plane in order to achieve a better sorting effect. However, the simple channel feeding method commonly used in industry often results in phenomena such as multi-layer superposition of particles, particle accumulation, and uneven particle feeding, which causes particles to collide with each other on the sorting table, thus affecting the movement trajectory of particles during sphericity sorting. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a monodisperse feeding device for fine sorting of particle sphericity, suitable for fine sorting of particle sphericity, which feeds particles monodisperse to avoid collisions between particles, while also making full use of space and increasing the feeding rate.

[0006] A monodisperse feeding device for fine sorting of particle sphericity according to an embodiment of the present invention includes an arc-shaped feeder. The arc-shaped feeder extends in an arc direction and includes a channel feed inlet, a tangential discharge outlet, a primary channel, a secondary channel, and a fine groove channel. The channel feed inlet and the tangential discharge outlet are respectively located at the two ends of the arc direction of the arc-shaped feeder. The primary channels are sequentially spaced along the radial direction of the arc-shaped feeder and extend in an arc shape from the channel feed inlet toward the tangential discharge outlet, for allowing the feed from the channel feed inlet to pass through the channel feed inlet. The particles entering from the primary channel are separated; the secondary channels are distributed radially at intervals along the arc-shaped feeder and extend in an arc shape from the outlet of the primary channel toward the tangential outlet, for further separating the particles from the outlet of the primary channel; the fine groove channels are distributed radially at intervals along the arc-shaped feeder and extend in an arc shape from the outlet of the secondary channel to the tangential outlet, for making the particles from the outlet of the secondary channel evenly dispersed in a single layer and flow toward the tangential outlet.

[0007] The working principle of the monodisperse feeding device for fine particle sphericity sorting in this embodiment of the utility model is as follows: the arc-shaped feeder adjusts the vibration so that the particles from the upstream particle conveying channel are first forcibly spread and separated through the first-level channel, and then further forcibly spread and separated through the second-level channel, and finally enter the fine groove channel. The particles covering the fine groove channel are spread evenly and dispersed in a single layer and flow to the tangential discharge port. From the tangential discharge port, they fall onto the table of the downstream particle sphericity fine sorting device below, thereby realizing the uniform dispersion, single-layer spreading, and complementary feeding of particles to the downstream particle sphericity fine sorting device.

It can ensure the monodisperse of particles and greatly improve efficiency, and has a wide range of application scenarios.

[0011] In some embodiments, the arc lengths of the different primary arc ribs along the radial direction from the inside to the outside of the arc feeder increase sequentially.

[0012] In some embodiments, the radial width between the outer arc-shaped wall panel and the inner arc-shaped wall panel gradually increases in the direction from the channel inlet to the tangential outlet, and the radial width of the primary channel also gradually increases.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is combined with Figure 1 and Figure 2 This invention describes a monodisperse feeding device for fine sorting of particle sphericity according to an embodiment of the present invention.

[0026] A monodisperse feeding device for fine sorting of particle sphericity according to an embodiment of the present invention includes an arc-shaped feeder 1.

[0027] Specifically, the arc-shaped feeder 1 extends in an arc direction and includes a channel feed inlet 101, a tangential discharge outlet 105, a primary channel 102, a secondary channel 103, and a fine groove channel 104.

[0028] The channel inlet 101 and the tangential outlet 105 are located at opposite ends of the arc of the arc-shaped feeder 1. The channel inlet 101 is connected to the upstream particle conveying channel, and the tangential outlet 105 is connected to the downstream particle sphericity fine sorting equipment. The primary channel 102 is distributed radially along the arc-shaped feeder 1 and extends from the channel inlet 101 toward the tangential outlet 105, used to separate particles entering from the channel inlet 101. The secondary channel 103 is located along... The arc-shaped feeder 1 is radially spaced and extends from the outlet of the primary channel 102 toward the tangential outlet 105, which is used to further separate the particles from the outlet of the primary channel 102; the fine channel 104 is radially spaced and extends from the outlet of the secondary channel 103 to the tangential outlet 105, which is used to make the particles from the outlet of the secondary channel 103 spread evenly in a single layer and flow toward the tangential outlet 105.

[0029] Among them, the primary channel 102, the secondary channel 103 and the fine groove channel 104 extend in an arc shape, which can change the movement direction of the particles. The design of the primary channel 102 forces the particles from the upstream particle transport channel to separate, the design of the secondary channel 103 further separates the particles, and the design of the fine groove channel 104 further regularizes the particle arrangement and feeding process, achieving the degree of single particle dispersion, so that the particles from the secondary channel 103 are evenly dispersed in a single layer and flow towards the tangential discharge port 105.

[0030] The working principle of the monodisperse feeding device for fine particle sphericity sorting in this embodiment of the utility model is as follows: the arc-shaped feeder 1 adjusts the vibration so that the particles from the upstream particle conveying channel are first forcibly spread and separated through the primary channel 102, and then further forcibly spread and separated through the secondary channel 103, and finally enter the fine groove channel 104. The particles covering the fine groove channel 104 are spread evenly in a single layer and flow towards the tangential discharge port 105. They fall from the tangential discharge port 105 onto the table of the downstream particle sphericity fine sorting device below, thereby realizing the uniform dispersion, single-layer spreading, and complementary feeding of particles to the downstream particle sphericity fine sorting device.

[0031] The monodisperse feeding device for fine particle sphericity sorting according to this embodiment of the invention has the following advantages: The arc-shaped feeder 1, through the design of a primary channel 102, a secondary channel 103, and a fine-screw channel 104, achieves uniform dispersion, single-layer flat feeding of particles, and complementary feeding to the downstream fine particle sphericity sorting equipment. On the one hand, this improves the particle sphericity sorting effect of the downstream fine particle sphericity sorting equipment; on the other hand, it meets the industrial production requirements for achieving monodisperse flat feeding of particles, avoiding collisions between particles, and making full use of space to increase the feeding rate. Furthermore, the monodisperse feeding device for fine particle sphericity sorting according to this embodiment of the invention has a simple structure and is easy to use.

[0032] The monodisperse feeding device for fine sorting of particle sphericity according to this utility model embodiment is not only suitable for the field of fine sorting of nuclear fuel particle sphericity, but also applicable to other fields that require monodisperse and flat feeding of particles, such as individual packaging of spherical products. It can ensure the monodisperse of particles and greatly improve efficiency, and has a wide range of application scenarios.

[0033] It should be noted that if the length of the arc-shaped feeder 1 is relatively long, a third-level channel or even more channels can be added between the secondary channel 103 and the fine-mark channel 104. The particles flowing out of the outlet of the previous channel are forcibly separated by the next-level channel, so as to achieve uniform dispersion of particles, single-layer flat laying, and complementary influence on feeding to the downstream particle sphericity fine sorting equipment.

[0034] In some embodiments, the arc-shaped feeder 1 includes an arc-shaped base plate 106, an outer arc-shaped wall plate 107, an inner arc-shaped wall plate 108, a primary arc-shaped rib 109, a secondary arc-shaped rib 1010, and a tertiary arc-shaped rib 1011; the outer arc-shaped wall plate 107 and the inner arc-shaped wall plate 108 are respectively fixed to the outer arc edge and the inner arc edge of the arc-shaped base plate 106 opposite to each other; the primary arc-shaped ribs 109 are arranged sequentially at intervals along the radial direction of the arc-shaped feeder 1 on the arc-shaped base plate 106 and from the channel feed port 1011. The first-stage channel 102 is formed by extending from the outlet of the first-stage channel 102 towards the tangential outlet 105; the second-stage arc-shaped ribs 1010 are arranged in a series of intervals along the radial direction of the arc-shaped feeder 1 on the arc-shaped base plate 106 and extend from the outlet of the first-stage channel 102 towards the tangential outlet 105 to form the second-stage channel 103; the third-stage arc-shaped ribs 1011 are arranged in a series of intervals along the radial direction of the arc-shaped feeder 1 on the arc-shaped base plate 106 and extend from the outlet of the second-stage channel 103 to the tangential outlet 105.

[0035] The arc-shaped feeder 1, through the design of an arc-shaped base plate 106, an outer arc-shaped wall plate 107, an inner arc-shaped wall plate 108, a primary arc-shaped rib 109, a secondary arc-shaped rib 1010, and a tertiary arc-shaped rib 1011, forms a primary channel 102, a secondary channel 103, and a fine-line channel 104. This design enables the uniform dispersion, single-layer flat feeding of particles, and complementary influence feeding to downstream particle sphericity fine sorting equipment. This is beneficial to improving the particle sphericity sorting effect of downstream particle sphericity fine sorting equipment. At the same time, it can meet the requirements of industrial production to achieve single-dispersion flat feeding of particles, avoid collisions between particles, make full use of space, and improve the feeding rate. In addition, the single-dispersion feeding equipment for particle sphericity fine sorting in this embodiment has a simple structure and is easy to use.

[0036] In some embodiments, along the radial direction from the inside to the outside of the arc-shaped feeder 1, the arc lengths of the different first-stage arc-shaped ribs 109 increase sequentially. This facilitates the uniform dispersion of particles for feeding into downstream particle sphericity fine sorting equipment or other equipment.

[0037] In some embodiments, the radial width between the outer arc-shaped wall plate 107 and the inner arc-shaped wall plate 108 gradually increases in the direction from the channel inlet 101 to the tangential outlet 105, and the radial width of the primary channel 102 also gradually increases. This can reduce the particle movement speed and make it easier to control the particle movement trajectory.

[0038] In some embodiments, the fine groove 104 allows only a single layer and a single row of particles to pass through, achieving a degree of single-particle dispersion.

[0039] In some embodiments, the depth of the fine groove 101 is 1 / 4 to 1 / 3 times the particle diameter, and the center distance between adjacent fine grooves 101 is 1.02 to 1.05 times the particle diameter. This facilitates particle dispersion and positioning without generating groove resistance.

[0040] In some embodiments, the heights of the outer arc-shaped wall panel 107 and the inner arc-shaped wall panel 108 are both greater than those of the primary arc-shaped rib 109, the secondary arc-shaped rib 1010, and the tertiary arc-shaped rib 1011. This prevents particles from scattering from the radially outer and radially inner sides of the arc-shaped feeder 1 outside the arc-shaped feeder 1.

[0041] In some embodiments, the outlet end of the fine groove 104 has a downward slope. This facilitates the particles falling onto the table of the downstream particle sphericity fine sorting equipment and dispersing them, preventing them from interfering with each other when moving in two vertical directions.

[0042] In some embodiments, the downward slope of the outlet end of the fine groove 104 is 30-60 degrees. This facilitates the particles falling onto the table of the downstream particle sphericity fine sorting equipment and dispersing them, preventing them from interfering with each other when moving in two vertical directions.

[0043] In some embodiments, the outer arc-shaped wall panel 107 and the inner arc-shaped wall panel 108 are provided with a connecting portion 1012 at one end near the feed inlet 101 of the channel, which connects to the upstream particle conveying channel. This facilitates disassembly and installation with the upstream particle conveying channel.

[0044] Specifically, the connecting part 1012 is provided with a snap-fit ​​groove 10121, which is connected to the upstream particle transport channel for easy disassembly and installation.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
