Description

Technical Field

[0001] This utility model relates to the field of preparation device technology, and in particular to a preparation device for silicon carbide-based cladding material for nuclear reactors. Background Technology

[0002] With the continuous development and application of nuclear energy technology, the requirements for nuclear fuel cladding materials are also increasing. Silicon carbide, as an important material with excellent performance and wide application, has significant advantages in the field of nuclear fuel cladding due to its high melting point, high hardness, and high radiation resistance. The preparation device for silicon carbide-based cladding materials for nuclear reactors is a special equipment used to produce silicon carbide-based cladding materials. This device combines multiple process steps and equipment components to ensure that silicon carbide-based cladding materials can meet the stringent requirements of nuclear reactors for extreme conditions such as high temperature resistance, corrosion resistance, and radiation resistance.

[0003] In the process of using the equipment for preparing silicon carbide-based cladding materials for nuclear reactors, the pre-prepared silicon carbide-based materials, additives, modifiers and other auxiliary materials need to be placed in a high-temperature reactor for heat treatment. However, since various raw materials may contain particles with large particle sizes, the raw materials with large particle size differences will exhibit different reaction rates and reaction degrees in a high-temperature environment, thereby reducing the overall performance of the silicon-based cladding material. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, during the use of the above-mentioned equipment, large particles may be mixed in with various raw materials, which reduces the overall performance of the silicon-based cladding material. Therefore, this invention proposes a device for preparing silicon carbide-based cladding material for nuclear reactors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a preparation device for silicon carbide-based cladding material for nuclear reactors, comprising a conveying mechanism, wherein a separation mechanism is fixedly connected to the top of the conveying mechanism;

[0006] The separation mechanism includes a separation box, with a feed hopper fixedly connected to the top of the separation box. Two fixed rods are fixedly connected to the inner wall of the feed hopper. A set of springs is movably fitted onto the outer wall of each of the two fixed rods. A movable column is movably fitted onto the outer wall of each of the two fixed rods. A screen is fixedly connected between one side of the outer wall of the two movable columns. Two baffles are fixedly installed on the top of the screen. A mounting base is fixedly installed on one side of the outer wall of the screen. A connecting rod is movably fitted onto the outer wall of the mounting base. A rotating rod is movably inserted into the inner wall of the connecting rod. A rotating disk is fixedly connected to the bottom of the rotating rod. A second motor is fixedly connected to the bottom of the rotating disk. A guide plate is fixedly connected to one side of the outer wall of the separation box. A placement box is fixedly connected to one side of the outer wall of the separation box. Two sliding grooves are formed on one side of the outer wall of the placement box. A slider is slidably embedded into the inner wall of each of the two sliding grooves. A sliding cabinet is fixedly connected between one side of the outer wall of the two sliders. A handle is fixedly installed on one side of the outer wall of the sliding cabinet.

[0007] Preferably, the conveying mechanism includes a high-temperature treatment furnace, a support frame is fixedly installed on the outer wall of the high-temperature treatment furnace, and a conveying pipe is fixedly connected to the top of the support frame.

[0008] Preferably, the outer wall of the conveying pipe has two mounting grooves, and bearings are fixedly inserted into the inner wall of each of the two mounting grooves.

[0009] Preferably, a rotating shaft is fixedly inserted between the inner walls of the two bearings, and a helical blade is fixedly sleeved on the outer wall of the rotating shaft.

[0011] Preferably, a discharge valve is provided on the inner wall of the discharge pipe, and a feeding hopper is fixedly connected to the outer wall of the separation box.

[0012] Preferably, the input end of the feeding hopper is fixedly connected to the bottom of the separation box.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, through the interaction of the components of the separation mechanism, efficient screening of various raw materials can be achieved, thereby effectively screening raw materials with larger particle sizes. This screening process ensures that the particle size distribution of the raw materials is more uniform before entering the subsequent processing stage, thus exhibiting a more consistent reaction rate and reaction degree in a high-temperature environment, which significantly improves the overall performance of the silicon-based coating material. Furthermore, driven by the second motor, the screen can continuously shake, which not only improves the screening efficiency but also effectively prevents the screen from clogging due to the accumulation of raw materials.

[0015] In this invention, through the cooperation of the separation mechanism and the conveying mechanism, and driven by the first motor, the automatic conveying of various raw materials can be achieved, thereby greatly improving production efficiency and ease of operation. During the conveying process, the various raw materials will continuously mix and interact, thus promoting the uniform distribution and thorough mixing of the raw materials.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figures 1-5 As shown, this utility model provides a device for preparing silicon carbide-based cladding material for nuclear reactors, including a conveying mechanism 1, and a separation mechanism 2 fixedly connected to the top of the conveying mechanism 1;

[0027] The separation mechanism 2 includes a separation box 201, with a feed hopper 202 fixedly connected to the top of the separation box 201. Two fixed rods 203 are fixedly connected to the inner wall of the feed hopper 202. A set of springs 204 is movably sleeved on the outer wall of each of the two fixed rods 203. Moving columns 205 are movably sleeved on the outer wall of each of the two fixed rods 203. A screen 206 is fixedly connected between one side of the outer wall of the two moving columns 205. Two baffles 207 are fixedly installed on the top of the screen 206. A mounting base 208 is fixedly installed on one side of the outer wall of the screen 206. A connecting rod 209 is movably sleeved on the outer wall of the mounting base 208. A rotating rod 210 is movably inserted into the inner wall of the connecting rod 209. A rotating disk 211 is fixedly connected to the bottom of the rotating rod 210. A second motor 212 is fixedly connected to the bottom of the rotating disk 211. A guide plate 213 is fixedly connected to one side of the outer wall of the separation box 201. A placement box 214 is fixedly connected to one side of the outer wall of the separation box 201. Two sliding grooves 215 are opened on one side of the outer wall of the placement box 214. A slider 216 is slidably embedded in the inner wall of each of the two sliding grooves 215. A sliding cabinet 217 is fixedly connected between the outer walls of the two sliders 216. A handle 218 is fixedly installed on one side of the outer wall of the sliding cabinet 217.

[0028] The overall effect of Embodiment 1 is as follows: First, the second motor 212 is started. The output end of the second motor 212 drives the rotating disk 211 to rotate. Since the rotating rod 210 is fixedly installed at the eccentric position on the top of the rotating disk 211, and the connecting rod 209 is movably sleeved on the outer wall of the rotating rod 210, the rotation of the rotating disk 211 will drive the connecting rod 209 to reciprocate. The reciprocating motion of the connecting rod 209 will further drive the screen 206 to reciprocate. The reciprocating vibration of the screen 206 will, through the linkage of the moving column 205 and the two sets of springs 204, cause the screen 206 to vibrate. Within the fixed frame, the screen 206 continuously shakes. When various raw materials fall from the feed hopper 202 onto the top of the screen 206, the constantly shaking screen 206 effectively filters the raw materials. Raw materials with the required particle size will fall through the screen 206 into the feed hopper 111, while larger raw materials will slide down along the inclined direction of the screen 206 and, with the guidance of the guide plate 213, eventually slide into the slide cabinet 217. Through this screening process, it can be ensured that the raw materials entering the subsequent production stages have a relatively consistent particle size distribution, thereby improving the quality and performance of the products.

[0029] Example 2, as Figures 2-5 As shown, the conveying mechanism 1 includes a high-temperature treatment furnace 101. A support frame 102 is fixedly installed on the outer wall of the high-temperature treatment furnace 101. A conveying pipe 103 is fixedly connected to the top of the support frame 102. Two mounting grooves 104 are opened on the outer wall of the conveying pipe 103. Bearings 105 are fixedly inserted into the inner wall of each of the two mounting grooves 104. A rotating shaft 106 is fixedly inserted between the inner walls of the two bearings 105. A spiral blade 107 is fixedly sleeved on the outer wall of the rotating shaft 106. A first motor 108 is fixedly connected to one side of the outer wall of the rotating shaft 106. A feeding pipe 109 is fixedly connected to the outer wall of the high-temperature treatment furnace 101. A feeding valve 110 is provided on the inner wall of the feeding pipe 109. A feeding hopper 111 is fixedly connected to the outer wall of the separation box 201. The input end of the feeding hopper 111 is fixedly connected to the bottom of the separation box 201.

[0030] The effect achieved by the entire embodiment 2 is that when various raw materials fall into the interior of the conveying pipe 103 through the feeding hopper 111, the first motor 108 is started first. The output end of the first motor 108 drives the rotating shaft 106 to start rotating, which in turn causes the spiral blade 107 to rotate. During the rotation, the spiral blade 107 pushes the raw materials forward along the interior of the conveying pipe 103 through its spiral structure. During this process, the raw materials are subjected to the rotation of the spiral blade 107, which not only achieves the purpose of forward conveying, but also ensures that the various raw materials are fully mixed under the push of the spiral blade 107. Subsequently, the discharge valve 110 is opened, and the raw materials fall into the separation box 201 through the discharge pipe 109 for heat treatment.

[0031] Working Principle: After the equipment is started, the second motor 212 is activated first, and its output drives the rotating disk 211 to rotate. Because the rotating rod 210 is eccentrically mounted on the top of the rotating disk 211, and a connecting rod 209 is movably sleeved on the rotating rod 210, the rotation of the rotating disk 211 drives the connecting rod 209 to reciprocate. This reciprocating motion of the connecting rod 209 then drives the screen 206 to move synchronously. The screen 206, in turn, drives the two moving columns 205 to reciprocate. This reciprocating vibration is enhanced and stabilized by the linkage of two sets of springs 204, ensuring that the screen 206 can continuously and stably shake. Subsequently, the operator feeds various raw materials into the screen 206 through the feed hopper 202. Under the continuous shaking of the screen 206, the raw materials are effectively separated. Larger particles are separated by the guide plate 213. Guided by the material, the raw materials slide into the slide cabinet 217 for preliminary particle size classification. When the raw materials accumulate to a certain level inside the slide cabinet 217, the staff can easily slide the slide cabinet 217 out by pulling the handle 218 to process or collect the raw materials. At the same time, when the raw materials enter the conveying pipe 103 through the feeding hopper 111, the first motor 108 is started. The first motor 108 drives the rotating shaft 106 to rotate, which in turn drives the spiral blades 107 to rotate. During the rotation, the spiral blades 107 push the raw materials forward along the conveying pipe 103 through their spiral structure, achieving preliminary mixing and homogenization of the raw materials. When the raw materials that have completed preliminary mixing reach the end of the conveying pipe 103, the discharge valve 110 is opened, and the raw materials enter the separation box 201 through the discharge pipe 109 for heat treatment.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
