Description

Technical Field

[0001] This application belongs to the field of deformed clothing particle removal technology, and particularly relates to a deformed clothing particle removal platform structure and removal method. Background Technology

[0002] To ensure that the TRISO-coated fuel particles are not damaged by stress during the pressing of spherical fuel elements in a high-temperature gas-cooled reactor, thus compressing their safety characteristics, a layer of base graphite powder is coated on the outside of the fuel particles as a buffer layer (hereinafter referred to as: the coating layer). This eliminates the stress between the particles during the pressing of the spherical fuel elements, protects the coating, and ensures that the inherent safety characteristics of the coated fuel particles are not compromised during the pressing of the spherical fuel elements.

[0003] The coating thickness is designed to be approximately 0.25 mm. The preparation process uses ethanol as a binder to continuously bond and grow the substrate graphite powder. The resulting coated particles contain impurities with poor coating thickness, sphericity, and deformed particles (twins, triplets, etc.). Unsatisfactory coated particles are removed through sieving and vibration selection. Two problems were found during the use of the existing equipment:

[0004] (1) Limited ability to remove deformed clothing particles. During production and use, it was found that the ability to remove deformed clothing particles was weak, resulting in a large number of "twin" particles being mixed in with the selected qualified clothing particles.

[0005] (2) The vibration separation efficiency is low. Due to the limited ability of the existing device to remove deformed clothing particles, the feeding rate must be strictly controlled at about 0.5 kg / h when the clothing particles are selected by vibration separation, so as to prevent the particles from colliding with each other on the table, interfering with the running trajectory of deformed clothing particles on the vibration separation table, and affecting the removal rate of deformed clothing particles.

[0006] Cleaning tests revealed that the deformed clothing pellets, such as the "twins," were mostly substandard pellets with a coating thickness lower than the design requirement (0.25mm) and a particle diameter of 2. Because the coating thickness did not meet the design requirements, the stress relief ability during the pressing process was not as good as expected. As a result, the stress during the pressing process could not be offset, leading to a high risk of cracking of the TRISO-coated fuel pellet coating during the pressing process. This resulted in low efficiency, affecting the production efficiency of qualified clothing pellets and posing a risk to the production of downstream clothing processes. Summary of the Invention

[0007] The purpose of this application is to provide a deformed clothing particle removal platform structure and removal method, which solves the problem of low removal rate of deformed clothing particles in the prior art.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] In a first aspect, this application provides a deformed clothing particle removal platform structure, comprising:

[0010] The material feeding buffer preliminary selection area is located in the upper right corner of the table, and the material feeding buffer preliminary selection area is provided with a first U-shaped boss structure;

[0011] The main selection area is located in the middle of the table surface, and the main selection area is provided with a first U-shaped boss structure;

[0015] In some embodiments, the protrusion of the first U-shaped boss structure faces the upper right corner.

[0016] In some embodiments, the number of the second U-shaped boss structures is 2.

[0026] Step 4: Remove deformed clothing particles that have escaped from the initial selection area and main selection area through the deformed clothing particle removal protection area.

[0027] Step 5: After vibration separation, collect the clothing particles.

[0028] Compared with the prior art, the deformed clothing particle removal platform structure and removal method provided in this application have the following advantages:

[0029] By observing that the movement of deformed clothing particles exhibits an "uphill" characteristic, this application achieves the technical effect of reducing the impulse of vibratory-selected particles and performing preliminary selection of the clothing particles to be vibrated by designing a feeding buffer initial selection zone. This application also achieves the technical effect of separating and removing deformed clothing particles from qualified clothing particles by designing a main selection zone. Finally, this application achieves the technical effect of removing deformed clothing particles by designing a deformed clothing particle removal guarantee zone.

[0030] This application achieves optimal particle dispersion on the vibratory separation table by designing the above three zones of the table and selecting surface coating materials, reducing the probability of particle collision and interference between particles on the vibratory separation table, increasing the utilization rate of the vibratory separation table, increasing the feed rate by about 1.0 times, and realizing the technical effect of improving the working efficiency of the vibratory separation table.

[0041] The following detailed description provides further details on specific implementation methods.

[0042] like Figures 1 to 5 As shown, this application provides a deformed clothing particle rejection table structure, which has a feeding buffer initial selection area 1, a main selection area 2, and a deformed clothing particle rejection protection area 3. The feeding buffer initial selection area 1 is located in the upper right corner of the table, the main selection area 2 is located in the middle of the table, and the deformed clothing particle rejection protection area 3 is located in the lower left corner of the table.

[0043] like Figures 1 to 3 As shown, the material feeding buffer preliminary selection area 1 is located in the upper right corner of the table. The material feeding buffer preliminary selection area 1 is composed of a set of first U-shaped boss structures.

[0044] Preferably, the first U-shaped protrusion structures are arranged in an array, with 5 first U-shaped protrusion structures arranged in the first row, 4 first U-shaped protrusion structures arranged in the second row, 5 first U-shaped protrusion structures arranged in the third row, 4 first U-shaped protrusion structures arranged in the fourth row, 5 first U-shaped protrusion structures arranged in the fifth row, and 4 first U-shaped protrusion structures arranged in the sixth row.

[0045] Optionally, the protrusions of the first U-shaped boss structure in this group all face the upper right corner.

[0046] The main functions of the feeding buffer primary selection zone 1 include: offsetting the impulse of clothing particles, ensuring the dispersion and vibration of clothing particles, and reducing mutual interference between clothing particles during the vibration and selection process.

[0047] The main way to offset the impulse of the clothing particles is by using regular and dispersed U-shaped protrusion structures (first U-shaped protrusion structure) to offset the impulse of the clothing particles that initially arrive at the vibratory separation table, so as to eliminate the influence of the impulse generated during the feeding process of clothing particles on the running trajectory of clothing particles in the vibratory separation process, and ensure that the clothing particles are in a controlled vibration optimization state on the table of the vibration optimization device.

[0048] To ensure the dispersed vibration separation of clothing particles and reduce mutual interference during the separation process, the following measures are taken: Utilizing regular, dispersed small U-shaped protrusions, arranged in a regular pattern according to process requirements, to form multiple channels for the clothing particle vibration separation and feeding. This ensures the dispersed movement of the clothing particles during the separation process, creating multiple channels for the clothing particle table and reducing the probability of collisions between the particles, thereby minimizing mutual interference during the separation process.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, the main selection area 2 is located in the middle of the tabletop, and the main selection area 2 is composed of a set of second U-shaped boss structures.

[0050] Preferably, the group of second U-shaped boss structures includes two second U-shaped boss structures, which are arranged facing the upper right corner and at an oblique angle.

[0051] Optionally, the second U-shaped boss structure of this group is arranged in an array.

[0052] Optionally, the second U-shaped boss structure is larger in size than the first U-shaped boss structure.

[0053] The main function of the main selection area 2 is to deeply remove deformed clothing particles 4, thereby improving the removal rate of deformed clothing particles. This is mainly manifested in the fact that when qualified clothing particles 5 and deformed clothing particles 4 flow through the main selection area 2, they are separated by the combined effects of friction, gravity, vibration, and trajectory guidance of the long U-shaped boss structure (second U-shaped boss structure). This diverts most of the deformed clothing particles 4 towards the unqualified area. Since the main selection area 2 is located in the middle of the platform, the deformed clothing particles 4 are close to the unqualified clothing particle collection bin after being diverted, and the risk of entering the qualified bin is low, thus significantly improving the removal rate of deformed clothing particles.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, the deformed clothing particle removal protection area 3 is located in the middle of the table, and the deformed clothing particle removal protection area 3 is composed of a set of third U-shaped protrusion structures.

[0055] Preferably, the third U-shaped boss structure in this group is a single second U-shaped boss structure, and the second U-shaped boss structure is arranged facing the upper right corner.

[0056] Optionally, the third U-shaped boss structure is larger than the first U-shaped boss structure.

[0057] The main function of the deformed clothing particle removal protection zone 3 is to consolidate the removal effect of deformed clothing particles and remove deformed clothing particles 4 that have escaped from the main selection zone 2. This is mainly manifested in the deep removal of a small number of deformed clothing particles 4 that have not been removed in the material feeding buffer primary selection zone 1 and the main selection zone 2. It is also the last barrier to remove deformed clothing particles 4 in the vibration separation process.

[0058] Based on the design principle of the deformed clothing particle rejection protection zone 3 and the actual deformed clothing particle rejection test, even if the deformed clothing particles 4 are not effectively rejected after passing through the feeding buffer primary selection zone 1 and the main selection zone 2, the running trajectory of the deformed clothing particles 4 is getting closer and closer to the vibration selection unqualified area. After the guiding effect of the deformed clothing particle rejection protection zone 3, the running trajectory of these deformed clothing particles 4 can be effectively optimized, and the deformed clothing particles 4 can be guided to the vibration selection unqualified area, thus preventing the deformed clothing particles 4 from entering the qualified clothing particle area.

[0059] In addition, such as Figure 6 and Figure 7 As shown, this application also provides a method for removing deformed clothing particles, including the following steps:

[0060] Step 1: Feeding and setting garment pellets. Use the existing equipment to feed the garment pellets and set the corresponding parameters.

[0061] Step 2: The material arriving at the table is buffered and dispersed through the initial selection area 1, ensuring that the particles are evenly dispersed and removing deformed particles.

[0062] Step 3: Through the main selection area 2, the work of removing deformed clothing particles is carried out. Deformed clothing particles 4 and clothing particles 5 are diverted, which plays the main role in removing deformed clothing particles.

[0063] Step 4: By using the deformed clothing particle removal protection area 3, the deformed clothing particles 4 that "escaped" from the feeding buffer primary selection area 1 and the main selection area 2 are preferentially removed to ensure that the deformed clothing particles 4 can be removed in the largest possible quantity.

[0064] Step 5: After vibration separation, collect 5 pieces of clothing particles.

[0065] This application improves the worktable, achieving high-efficiency and high-performance removal of deformed clothing particles. It enables optimal particle dispersion on the vibratory separation table, reduces the probability of collisions and interference between clothing particles, increases the utilization rate of the vibratory separation table, increases the feed rate by approximately 1.0 times, and improves the table's working efficiency.

[0066] The above description is only a specific embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application.
