Description

Technical Field

[0001] This utility model belongs to the field of non-ferrous metal smelting and manufacturing technology. Specifically, it relates to a closed cleaning device adapted to cylindrical ingots of different specifications. This closed cleaning device is mainly used to assist in the high-quality production of zirconium and zirconium alloy ingots. Background Technology

[0002] In the field of non-ferrous metal materials, zirconium and zirconium alloys occupy an important position in high-tech fields such as aerospace and nuclear power due to their excellent properties. With their strong corrosion resistance, high strength, and good high-temperature resistance, zirconium and zirconium alloys can be used as structural components in the aerospace field to withstand extreme temperature and pressure changes, ensuring the safe and stable operation of aircraft. In the nuclear power field, they serve as ideal cladding materials, maintaining stable performance in high-radiation environments and ensuring the safe operation of nuclear reactors.

[0003] In the production of zirconium materials, ingot smelting is a crucial first step, as the quality of the ingot directly affects the quality, performance stability, and production cost of subsequent bars, tubes, and plates. Currently, vacuum consumable arc furnace (CAF) smelting is the main method for smelting zirconium alloy ingots. It utilizes the high temperature generated by an electric arc discharge as a heat source to melt the zirconium alloy consumable electrode, and the molten liquid undergoes physicochemical reactions to form an ingot in a crystallizer. However, during the smelting process, impurities in the zirconium alloy consumable electrode undergo ionization and vaporization reactions. Furthermore, factors such as cooling intensity, vacuum level, crystallizer cleanliness, and raw material quality can affect the ingot surface, resulting in a large amount of volatile deposits and oxide scale.

[0004] As is known in the industry, the surface quality of ingots is one of the important factors affecting the cost of zirconium materials. Poor ingot surface quality not only increases the loss from peeling but may also lead to problems such as cracking during subsequent forging, seriously affecting product quality and increasing product costs. Therefore, in the multiple smelting processes of a finished ingot, the ingot surface needs to be repeatedly cleaned between each smelting step to remove easily detachable adhering substances. However, most current ingot cleaning is done manually, with workers repeatedly scrubbing the ingot surface with stainless steel brushes to remove dirt, ash, oxides, chlorides, and other impurities. This cleaning method suffers from low cleaning efficiency, high labor intensity for workers, and environmental pollution caused by dust, making it unsuitable for large-scale production.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.

[0055] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0056] Please see Figures 1-10 This utility model provides a closed cleaning device adapted to cylindrical ingots of different specifications, including a platform 1, a cleaning chamber 2, an idler roller trolley 3, an idler roller trolley moving drive device 4, an idler roller rotating drive device 5, a brush head device 6, and a sludge collection cart 7. The platform 1 serves as the transmission and support unit; the cleaning chamber 2, idler roller trolley 3, idler roller trolley moving drive device 4, idler roller rotating drive device 5, and brush head device 6 are all mounted on the platform 1; the sludge collection cart 7 is located at the bottom of the platform 1.

[0057] like Figure 3As shown, the spatial layout of each component in the enclosed cleaning equipment of this utility model embodiment is as follows: the cleaning chamber 2 is fixedly set on the rear side of the platform 1; the roller trolley moving drive device 4 is located at the front of the cleaning chamber 2, and its function is to drive the roller trolley 3 set between the two to enter and exit the cleaning chamber 2 in the horizontal direction (first direction); the roller rotation drive device 5 is located on the upper outer side of the cleaning chamber 2 and is slidably set on the platform 1 in the horizontal direction. The roller rotation drive device 5 moves synchronously with the roller trolley 3 and drives the roller assembly 32 on the roller trolley 3 body 31 to rotate, so as to realize that the ingot A to be cleaned supported by it rotates around its own axis; the brush head device 6 is located on the rear side of the cleaning chamber 2 and is slidably set on the platform 1 in the vertical direction (second direction). The brush head 61 of the brush head device 6 extends into the cleaning chamber 2 and performs cleaning operation along the axis of the ingot A to be cleaned through rotational movement; the sludge collection cart 7 is set at the bottom of the platform 1 and below the cleaning chamber 2, and is used to collect the sludge generated during cleaning. It should be noted that the spatial layout of the components described above is merely an example and not a specific limitation, as long as the relative positional relationships between the components are satisfied. For example, provided that the first and second directions are perpendicular, their directions can be interchanged.

[0058] Specifically, in this embodiment of the utility model, the platform 1 is made of welded steel plates and consists of two parts, an upper steel plate that is vertically arranged and a lower steel plate that is horizontally arranged towards the front, forming a near-cross shape. Figures 1-3 As shown, the bottom of the platform 1 is fixedly connected to the foundation via adjustable support legs to ensure the stability of the platform 1 and thus guarantee the flatness of the platform surface. Preferably, the bottom surface of the platform 1 located below the cleaning chamber 2 is designed as a funnel structure to facilitate the collection of waste generated from the cleaning chamber 2 by the waste collection truck 7. In addition, a first guide rail 11 is arranged horizontally on the lower platform surface.

[0059] In this embodiment of the invention, the cleaning chamber 2 is fixedly mounted on the upper steel plate of the platform 1, forming a closed cavity structure with multiple transparent observation windows for monitoring the condition inside the chamber. Furthermore, a lifting door 21 is provided on the front side of the cleaning chamber 2 (facing the first guide rail 11). The structure of the lifting door 21 is not specifically limited in this invention, as long as it allows the ingot to enter and exit the cleaning chamber 2. For example, this embodiment uses a traditional electric lifting door, the specific structure of which will not be described in detail here.

[0060] like Figure 5 , 6As shown in this embodiment of the invention, the idler roller 3 includes a carriage body 31 and an idler roller assembly 32. The carriage body 31 is a steel structure with a copper sliding plate mounted on one end and a roller mounted on the other. The end with the copper sliding plate is mounted on the upper steel plate of the platform 1, and the end with the roller is mounted on the first guide rail 11 on the lower steel plate surface of the platform 1. The idler roller assembly 32 includes a driving roller 321 and a driven roller 322 arranged parallel to each other along a second direction. The bearing seats at both ends of the driving roller 321 are fixedly mounted on the carriage body 31. The bearing seats at both ends of the driven roller 322 are slidably connected to a sliding base 323 fixedly mounted on the carriage body 31, meaning the driven roller 322 can slide horizontally relative to the driving roller 321. The bearing seats at both ends of the driving roller 321 and the driven roller 322 are connected by a telescopic adjusting rod 324 to adjust the center distance between the driving roller 321 and the driven roller 322, so as to support cylindrical ingots of different specifications. Preferably, stainless steel support rings are installed on both rollers to prevent the zirconium alloy ingot from directly contacting the carbon steel roller, thereby ensuring the quality of the zirconium alloy ingot.

[0061] In this embodiment of the invention, the roller trolley moving drive device 4 includes a first motor 41 and a first lead screw 42 disposed at the output end of the first motor 41. The first motor 41 is fixedly disposed at the front end of the lower steel plate of the platform 1. One end of the first lead screw 42 is connected to the output shaft of the first motor 41 via a coupling, and the other end is threadedly connected to a first lead screw nut 43 fixedly disposed on the trolley body 31. With this configuration, the first motor 41 drives the first lead screw 42 to rotate, thereby pushing the roller trolley 3 and the supported ingot to reciprocate on the first guide rail 11, realizing the movement of entering and exiting the cleaning chamber 2.

[0062] In this embodiment of the invention, in order to ensure that the ingot is cleaned evenly around its entire circumference, a roller rotation drive device 5 is specially provided to drive the roller assembly 32 to rotate. The roller rotation drive device 5 is located on the upper edge of the platform 1, and its output end extends into the cleaning chamber 2 and is connected to the roller assembly 32. It is used to drive the roller assembly 32 to rotate, thereby driving the ingot to rotate and ensuring that all parts of the ingot are thoroughly cleaned.

[0063] like Figure 7 , 8As shown, specifically, the roller rotation drive device 5 includes a second guide rail 51 located outside the cleaning chamber 2 and horizontally arranged along the upper edge of the platform 1, a second motor 52 slidably mounted on the second guide rail 51, and a roller rotation transmission mechanism 53 mounted on the drive output end of the second motor 52. The roller rotation transmission mechanism 53 includes a drive shaft 531, a first drive wheel 532, a transmission component 533, and a support base 534 fixedly mounted on the vehicle body 31. One end of the drive shaft 531 is connected to the output shaft of the second motor 52, and the other end passes through the support base 534 and extends into the cleaning chamber 2, where the first drive wheel 532 is fixedly mounted. The first drive wheel 532 is connected to a second drive wheel 535 fixedly mounted at the end of the drive roller 321 via the transmission component 533. With this setup, the roller rotation drive device 5 moves synchronously with the roller carriage 3. When the roller carriage 3 enters the cleaning chamber 2 to clean the ingot, the second motor 52 is started to drive the transmission shaft 531 to rotate the first transmission wheel 532. At the same time, the first transmission wheel 532 drives the second transmission wheel 535 to rotate under the action of the transmission component 533, thereby realizing the action of rotating the active roller 321 and driving the ingot A to be cleaned to rotate around its own axis.

[0064] Furthermore, the transmission component 533 can be a belt, chain, or gear, and the corresponding first transmission wheel 532 and second transmission wheel 535 can be pulleys, sprockets, or gears. Different transmission methods can be selected based on factors such as the actual weight of the ingot to meet different working conditions and performance requirements. For example, in practical applications, if cleaning heavier zirconium alloy ingots, chain and sprocket transmission is preferred because this transmission method can handle larger torque transmissions, ensuring stable and efficient rotation of the roller assembly 32 even when carrying heavier ingots, thereby driving the ingot to rotate around its own axis.

[0065] like Figure 9 , 10As shown, in this embodiment of the present invention, the brush head device 6 includes a third guide rail 62 arranged vertically (parallel to the ingot) on the rear edge of the platform 1. A brush head support 63 connected to the brush head 61 is slidably arranged on the third guide rail 62. A brush head moving mechanism 64 is provided on the platform 1 to drive the brush head support 63 to reciprocate linearly along the third guide rail 62. At the same time, a brush head rotating mechanism 65 is installed on the brush head support 63 to drive the brush head 61 to rotate. In addition, there is a brush head adjustment mechanism 66 for adjusting the distance between the brush head 61 and the ingot A to be cleaned in the horizontal direction, as well as a rinsing nozzle 67 and a compressed air nozzle 68 disposed above the brush head 61. The rinsing nozzle 67 and the compressed air nozzle 68 are respectively connected to the corresponding water source and air source through pipelines so that during the cleaning process, the rinsing nozzle 67 can rinse the residue on the ingot and the worktable, and the compressed air nozzle 68 can blow away these residues, cool the zirconium alloy ingot, and prevent the zirconium dust brushed off during the high-speed movement of the brush head from burning.

[0066] Specifically, the brush head moving mechanism 64 includes a third motor 641, a second lead screw 642, and a third nut 643 fixedly mounted on the brush head support 63 (the third nut 643 is fixedly mounted on the bottom of the brush head support 63). The third motor 641 is fixed to one end of the third guide rail 62. One end of the second lead screw 642 is connected to the output shaft of the third motor 641, and the other end is threadedly connected to the third nut 643. With this configuration, when the third motor 641 starts, it can drive the second lead screw 642 to rotate, which in turn drives the brush head support 63 and the brush head 61 located on the third guide rail 62 to reciprocate along the ingot axis via the third nut 643 threadedly connected to the second lead screw 642.

[0067] Furthermore, the brush head rotation mechanism 65 mainly consists of a fourth motor 651 mounted on the brush head support 63 and a transmission assembly 652. The transmission assembly 652 can be selected from gear drive, belt drive, or chain drive. The output shaft of the fourth motor 651 is connected to the central shaft of the brush head 61 through the transmission assembly 652, driving the brush head 61 to rotate around the central shaft. This design allows the brush head 61 to remove dirt from the surface of the ingot more efficiently during cleaning operations, improving the cleaning effect. At the same time, through the cooperation of the fourth motor 651 and the transmission assembly 652, the rotation speed and force of the brush head 61 can be adjusted according to different cleaning needs to adapt to the cleaning requirements of ingots of different specifications and materials.

[0068] Furthermore, the brush head adjustment mechanism 66 includes an adjusting screw 661 and a fixing nut 662. The adjusting screw 661 is threadedly connected to the end of the brush head support 63, and one end of the adjusting screw 661 extending into the brush head support 63 is threadedly connected to the fixing nut 662, which is movably mounted on the brush head support 63 and fixedly mounted on the bottom of the fourth motor 651. This configuration allows for slight adjustments to the distance between the brush head 61 and the ingot based on the ingot diameter or the degree of bristle wear, ensuring that the brush head 61 can perform the cleaning operation on the ingot in optimal condition. This adjustable design improves the flexibility and adaptability of the equipment, meeting the cleaning needs under different working conditions.

[0069] In this embodiment of the invention, the sewage collection truck 7 has a box-like structure. Rollers are installed at the bottom for movement, a sewage overflow hole is opened in the middle, and a filter screen for filtering debris is installed at the top. The sewage collection truck 7 can collect residual debris, sediment, and overflowing sewage, and can discharge it into a sewage well.

[0070] It should be noted that the motor used in this embodiment is preferably a geared motor, because geared motors have advantages over ordinary motors, such as improved torque output, enhanced system stability, and precise control output. Furthermore, the guide rail used is a linear guide rail to achieve smooth movement and precise guidance.

[0071] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0072] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
