Description

Technical Field

[0001] This utility model relates to the field of nuclear industry technology, and in particular to a receiving and collecting device for nuclear industry material plates. Background Technology

[0002] Nuclear energy, as a clean and efficient energy source, is widely used in power generation, medical treatment, scientific research, and other fields. However, nuclear energy equipment, especially nuclear fuel plates, is usually plate-shaped. In order to ensure its performance during experimental research and industrial processing, vapor deposition technology (physical vapor deposition, PVD) is usually used to coat and evaporate the fuel plates, followed by pretreatment of the fuel plates. The purpose of this pretreatment is to remove moisture and enhance the adhesion between the film and the substrate. Heating the substrate under high vacuum can desorb the gas adsorbed on the surface of the substrate.

[0003] Because the temperature rises gradually during the heating reaction, if the temperature or conditions for a full reaction are not reached, some waste materials or loosely bonded powder will be generated and fall off the material plate. If these materials are not collected, they will fall onto other components below, affecting the lifespan and usage requirements of the components below.

[0004] Therefore, a receiving mechanism is needed to collect the waste while preventing it from falling onto other components below, and to recycle the collected waste. Thus, we propose an automatic receiving and collecting device for plate processing reaction.

[0005] A method and apparatus for recovering raw materials from a multilayer composite material having at least one layer with an adhesive surface is disclosed in German patent document DE102013002407B3. This method and apparatus can be used to manufacture printing plates for printing media in the printing industry to obtain sufficiently pure recycled material. The method involves deep freezing the composite material to be processed (preferably using liquid nitrogen (N2)), then grinding and sieving it in the frozen state to remove any fine particles or dust as destructive components and collecting them for further possible recycling. The remaining material is then irradiated with ultraviolet light to achieve complete polymerization and fed into a classifier, from which the cover film particles are removed and collected as other parts and reusable raw material (PET). The remaining material may only consist of the original intermediate layer material and may be removed as reusable raw material (SBS) under further ultraviolet light irradiation. However, this method and apparatus for recovering raw materials from a multilayer composite material having at least one layer with an adhesive surface is not applicable to the processing and recycling of nuclear industry material plates.

[0006] To address the shortcomings of the existing technologies, providing a receiving and collecting device for nuclear industry material plates is a problem worthy of research. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of material plates that generate and fall waste or loosely bonded powder. If these are not collected, the powder or impurities will fall onto other components below, affecting the lifespan and performance requirements of those components. This invention provides a material receiving and collecting device for nuclear industry material plates, achieving the technical effect of preventing waste from falling onto other components below.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A material receiving and collecting device for nuclear industry material plates includes a protective shell, a fixed frame disposed inside the protective shell, an evaporation device disposed below the fixed frame, and a material plate disposed above the fixed frame. A material receiving cloth is disposed between the evaporation device and the material plate. A material collecting and cleaning mechanism is disposed at one end of the material receiving cloth, and an extension and retraction mechanism is disposed below the material receiving cloth.

[0010] The material collection and cleaning mechanism includes a material collection box located below one side of the fixed frame, a connecting block rotatably connected to the top of the inner wall of the material collection box, and a cleaning cloth fixedly connected to the connecting block. The cleaning cloth cleans the powder and impurities attached to it, thus preventing the powder and impurities attached to it from being not completely recovered.

[0011] The top opening of the collection box is located below one end of the receiving cloth, and the bottom of the collection box is inclined.

[0012] A torsion spring is sleeved on the rotating shaft of the connecting block and the collection box. The torsion of the torsion spring causes the surface of the cleaning cloth to come into contact with the surface of the receiving cloth. The torsion spring can apply force to the cleaning cloth and increase the friction between the cleaning cloth and the receiving cloth.

[0013] The cleaning cloth is made of ceramic fiber blanket, and the receiving cloth is made of ceramic fiber cloth. Both can work continuously at a high temperature of 600 degrees Celsius and have bendable flexibility.

[0014] The extension and retraction mechanism includes a roller bracket fixedly connected to both sides of the fixed frame, a main sprocket and a driven sprocket rotatably connected to the roller brackets on both sides, a receiving cloth roller fixedly connected to the inner rotating shaft of the driven sprocket, and a cloth pulling rod fixedly connected to one side of the receiving cloth.

[0015] The main sprocket and the driven sprocket are located at opposite ends of the fixed frame.

[0016] A servo motor is fixedly connected to the protective shell. The output end of the servo motor is connected to the main sprocket via a worm gear and a universal joint. The main sprocket and the driven sprocket are connected by a chain drive. The two ends of the fabric pulling rod are engaged with the outside of the chain. One side of the receiving fabric is wound on the receiving fabric reel, and the other side of the receiving fabric is fixedly connected to the fabric pulling rod. When extending, the receiving fabric is pulled out by following the movement of the chain (the fabric pulling rod is engaged with the outside of the chain, thus allowing for linear reciprocating motion). When retracting, the receiving fabric is wound up by the receiving fabric reel. At the same time, since the fabric pulling rod is engaged with the chain, it can prevent the receiving fabric from drooping during reciprocating motion. The main sprocket and the driven sprocket are positioned far from the ends of the material plate, so the receiving fabric can catch and recover any material falling off the entire area below the material plate.

[0017] The extension and retraction mechanism includes a roller bracket fixedly connected to both sides of the fixed frame, a main sprocket and a driven sprocket rotatably connected to the roller brackets on both sides, a driven roller fixedly connected to the inner shaft of the driven sprocket, a receiving cloth roller fixedly connected to the inner shaft of the main sprocket, a cloth pulling rod fixedly connected to the end of the receiving cloth, and a receiving cloth guide rail and a receiving cloth horizontal shaft disposed between the receiving cloth roller and the driven roller.

[0018] The main sprocket and the driven sprocket are located at opposite ends of the fixed frame.

[0019] The receiving cloth guide rail and the receiving cloth horizontal axis are fixedly connected to the fixing frame. The receiving cloth guide rail and the receiving cloth horizontal axis are located below the receiving cloth. The receiving cloth guide rail is a double-row grooved rail. The receiving cloth horizontal axis is evenly distributed on the double-row grooved rail of the receiving cloth guide rail to support the receiving cloth and prevent it from sagging. It is suitable for cases where the receiving cloth is long.

[0020] A servo motor is fixedly connected to the protective shell. The output end of the servo motor is connected to the main sprocket via a worm gear and a universal joint. The main sprocket and the driven sprocket are connected by a chain drive. The two ends of the cloth pulling rod are engaged with the outside of the chain. One side of the receiving cloth is wound on the receiving cloth roll, and the other side of the receiving cloth is fixedly connected to the cloth pulling rod. The surface of the receiving cloth is cleaned to avoid the risk of material plate contaminating the evaporation device. After the receiving process is completed, the receiving cloth is retracted and the received material is collected.

[0021] Positive and beneficial effects:

[0022] 1. The nuclear industry material receiving and collecting device transfers the nuclear material powder and impurities collected on the receiving cloth to the collection box during the rotation of the receiving cloth, facilitating further recycling. The cleaning cloth can interact with the receiving cloth to clean the powder and impurities attached to the receiving cloth, avoiding the situation where the powder and impurities attached to the receiving cloth are not completely recycled.

[0023] 2. The nuclear industry material receiving and collecting device has a receiving cloth that can receive all the material falling off the material plate. Then, the material collection and cleaning mechanism can clean the surface of the receiving cloth to avoid the risk of material plate contaminating the evaporation device. After the receiving process is completed, the receiving cloth is retracted and the falling material is collected.

[0024] 3. This nuclear industry material plate receiving and collecting device uses a receiving cloth guide rail and a receiving cloth horizontal axis to receive the receiving cloth, preventing it from sagging. It is suitable for situations where the receiving cloth is long. Attached Figure Description

Detailed Implementation

[0036] 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.

[0037] Example 1

[0038] like Figures 1 to 10 As shown, a nuclear industry material receiving and collecting device includes a protective shell 1, a fixed frame disposed inside the protective shell 1, an evaporation device 2 disposed below the fixed frame, and a material plate 3 disposed above the fixed frame. A receiving cloth 4 is disposed between the evaporation device 2 and the material plate 3. A material collecting and cleaning mechanism 5 is disposed at one end of the receiving cloth 4, and an extension and retraction mechanism 6 is disposed below the receiving cloth 4.

[0039] like Figures 1 to 4 As shown, the material collection and cleaning mechanism 5 includes a material collection box 7 located below one side of the fixed frame, a connecting block 8 rotatably connected to the top of the inner wall of the material collection box 7, and a cleaning cloth 9 fixedly connected to the connecting block 8. By setting the material collection box 7 on one side of the receiving cloth 4, the nuclear material powder and impurities collected on the receiving cloth 4 are transferred to the material collection box 7 during the rotation of the receiving cloth 4, which facilitates further recycling. The cleaning cloth 9 can interact with the receiving cloth 4 to clean the powder and impurities attached to the receiving cloth 5, avoiding the situation where the powder and impurities attached to the receiving cloth 4 are not completely recycled.

[0040] like Figures 2 to 3 As shown, the top opening of the collection box 7 is located below one end of the receiving cloth 4, and the bottom of the collection box 7 is inclined. By setting the bottom of the collection box 7 to be inclined, nuclear industry powder and impurities can be concentrated on one side of the bottom of the collection box 7 after recycling, making it convenient for recycling.

[0041] like Figures 2 to 4As shown, a torsion spring is sleeved on the rotating shaft of the connecting block 8 and the collection box 7. The torsion of the torsion spring causes the cleaning cloth 9 to contact the surface of the receiving cloth 4. By setting the connecting block 8 with the cleaning cloth 9 on the surface of the collection box 7, the cleaning cloth 9 is kept in contact with the surface of the receiving cloth 4 under the action of the torsion spring, and the dust and impurities attached to the surface of the receiving cloth 4 are cleaned. The cleaned dust and impurities fall into the collection box 7 to complete the waste collection. The torsion spring can also apply force to the cleaning cloth 9 to increase the friction between the cleaning cloth 9 and the receiving cloth 4.

[0042] The cleaning cloth 9 is made of ceramic fiber blanket, and the receiving cloth 4 is made of ceramic fiber cloth. By using the ceramic fiber cleaning cloth 9 and receiving cloth 4, they can work continuously at a high temperature of 600 degrees Celsius and have bendable flexibility, enabling long-term collection and transportation of nuclear industry dust in the heating environment of the nuclear industry.

[0043] like Figures 2 to 4 As shown, the extension and retraction mechanism 6 includes a roller bracket 10 fixedly connected to both sides of the fixed frame, a main sprocket 11 and a driven sprocket 12 rotatably connected to the roller brackets 10 on both sides, a receiving cloth roller 13 fixedly connected to the inner rotating shaft of the driven sprocket 12, and a cloth pulling rod 14 fixedly connected to one side of the receiving cloth 4. The main sprocket 11 and the driven sprocket 12 are located at both ends of the fixed frame.

[0044] like Figures 2 to 4 As shown, a servo motor 15 is fixedly connected to the protective housing 1. The output end of the servo motor 15 is connected to the main sprocket 11 via a worm gear and a universal joint. The main sprocket 11 and the driven sprocket 12 are connected by a chain drive. The two ends of the fabric pulling rod 14 are engaged with the outside of the chain. One side of the receiving cloth 4 is wound on the receiving cloth roll 13, and the other side of the receiving cloth 4 is fixedly connected to the fabric pulling rod 14. By setting the receiving cloth roll 13 and the fabric pulling rod 14 on both sides of the receiving cloth 4 respectively, the fabric can be extended by... The fabric pulling rod 14 follows the movement of the chain and is clamped on the outside of the chain, thus enabling linear reciprocating motion to pull out the receiving cloth 4. When retracting, the receiving cloth 4 is rolled up by the receiving cloth roll 13. At the same time, since the fabric pulling rod 14 is clamped on the chain, it can prevent the receiving cloth 4 from drooping during reciprocating motion. The main sprocket 11 and the driven sprocket 12 are located far from both ends of the material plate 3, so the receiving cloth 4 can receive and recycle the entire area below the material plate.

[0045] Furthermore, end-point baffles are provided on the drive horizontal shaft of the main sprocket 11 and the drive horizontal shaft of the driven sprocket 12 to prevent excessive stretching and retraction of the receiving cloth 4. Then, the material collection and cleaning mechanism works to clean the surface of the receiving cloth 4 to avoid the risk of material 3 contaminating the evaporation device. After the receiving process is completed, the receiving cloth 4 is retracted and the following material is collected.

[0046] Example 2

[0047] like Figures 5 to 9 As shown, the extension and retraction mechanism 6 includes a roller bracket 10 fixedly connected to both sides of the fixed frame, a main sprocket 11 and a driven sprocket 12 rotatably connected to the roller brackets 10 on both sides, a driven roller 16 fixedly connected to the inner rotating shaft of the driven sprocket 12, a receiving cloth roller 13 fixedly connected to the inner rotating shaft of the main sprocket 11, a cloth pulling rod 14 fixedly connected to the end of the receiving cloth 4, and a receiving cloth guide rail 17 and a receiving cloth horizontal shaft 18 disposed between the receiving cloth roller 13 and the driven roller 16. The main sprocket 11 and the driven sprocket 12 are located at both ends of the fixed frame.

[0048] like Figure 9 As shown, the receiving cloth guide rail 17 and the receiving cloth horizontal axis 18 are fixedly connected to the fixing frame. The receiving cloth guide rail 17 and the receiving cloth horizontal axis 18 are located below the receiving cloth 4. The receiving cloth guide rail 17 is a double-row grooved rail, and the receiving cloth horizontal axis 18 is evenly distributed on the double-row grooved rail of the receiving cloth guide rail 17. By setting the receiving cloth guide rail 17 and the receiving cloth horizontal axis 18 below the receiving cloth 4, the receiving cloth 4 is supported, and it is prevented from sagging. This is suitable for cases where the receiving cloth 4 is long.

[0049] like Figures 6 to 8 As shown, a servo motor 15 is fixedly connected to the protective housing 1. The output end of the servo motor 15 is connected to the main sprocket 11 via a worm gear and a universal joint. The main sprocket 11 and the driven sprocket 12 are connected by a chain drive. The two ends of the fabric pulling rod 14 are engaged with the outside of the chain. One side of the receiving cloth 4 is wound on the receiving cloth roll 13, and the other side of the receiving cloth 4 is fixedly connected to the fabric pulling rod 14. When extended, the fabric pulling rod 14 follows the movement of the chain and is engaged with the outside of the chain, thus enabling linear reciprocating motion to transfer the receiving cloth. When the material cloth 4 is pulled out and retracted, since the pulling rod 14 is clamped on the chain, the material cloth 4 can be rolled up by the material cloth receiving roller 13 when the chain is retracted. The main sprocket 11 and the driven sprocket 12 are located far from the two ends of the material plate 3. Therefore, the material cloth 4 can receive the material falling off the entire area of ​​the material plate. Then, the material collection and cleaning mechanism can clean the surface of the material cloth 4 to avoid the risk of the material plate contaminating the evaporation device. After the material receiving process is completed, the material cloth 4 is retracted and the falling material is collected.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
