Description
Technical Field
[0001] This utility model relates to the technical field of graphite component cleaning devices in nuclear industry cladding furnaces, specifically to a graphite component cleaning device. Background Technology
[0002] In industrial production, especially in industries involving high-temperature processes such as nuclear power, metallurgy, chemicals, and new energy, graphite components are widely used as key parts. Due to their long-term operation in harsh environments such as high temperature and high pressure, graphite components are highly susceptible to the adhesion of various impurities, including metal oxides, carbon deposits, and other reaction byproducts. The accumulation of these impurities not only affects the thermal conductivity of the graphite components, leading to reduced equipment operating efficiency, but may also cause corrosion and wear, severely shortening their service life and consequently increasing production costs and equipment maintenance frequency.
[0003] Traditional methods for cleaning graphite parts, such as manual grinding and acid washing, have many drawbacks. Manual grinding is inefficient and makes it difficult to ensure uniformity and thoroughness of cleaning. Furthermore, workers are susceptible to dust pollution during the process, which can harm their health. While acid washing can remove impurities to some extent, the use of acid not only pollutes the environment but can also corrode the graphite parts themselves, affecting their physical properties and chemical stability. With the increasing scale and precision of industrial production, higher demands are being placed on the efficiency, safety, and environmental friendliness of graphite part cleaning. Against this backdrop, the development of a new, efficient, and environmentally friendly graphite part cleaning device has become an urgent need for the industry. Utility Model Content
[0004] The purpose of this invention is to provide a graphite cleaning device to solve at least one of the aforementioned problems in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A graphite part cleaning device includes a turntable assembly and a lifting brush assembly. The turntable assembly includes a turntable, a pushing cylinder assembly and a positioning cylinder assembly. The pushing cylinder assembly drives the turntable to rotate, and the positioning cylinder assembly locks the rotation position of the turntable. The turntable is circumferentially spaced with a plurality of positioning fixtures, which are used to position the graphite part.
[0007] The lifting brush assembly includes a cylinder assembly, a brush support plate, a guide assembly, a brush drive motor, and brush assemblies. The cylinder assembly drives the brush support plate to move up and down. The guide assembly provides guidance for the up and down movement of the brush support plate. The brush drive motor is mounted on the brush support plate. The brush assemblies are located below the brush support plate. Multiple brush assemblies correspond one-to-one with multiple positioning fixtures. The brush drive motor drives the brush assemblies to rotate and clean the graphite parts on the positioning fixtures.
[0008] In this technical solution, multiple positioning fixtures are spaced circumferentially on the turntable. These fixtures define the positions of multiple graphite parts. The positioning cylinder assembly locks the turntable's rotation position, maintaining its stability during graphite part cleaning and preventing positional shifts that could affect cleaning efficiency. Furthermore, the cylinder assembly drives the turntable's rotation, sequentially rotating the positioning fixtures to their designated pick-and-place positions, facilitating the pick-and-place device's access to the graphite parts. Because the cylinder assembly drives the brush support plate to rise and fall, and the guide assembly guides the rise and fall of the brush support plate, the cylinder assembly, in conjunction with the guide assembly, ensures the smoothness of the rise and fall of the brush support plate. This also allows the brush drive motor mounted on the brush support plate, and the brush assembly driven by the brush drive motor, to rise and fall smoothly. The brush assembly rises when parts need to be picked up or placed, and falls when the placed graphite parts need to be cleaned. The brush drive motor then rotates the brush assembly, thus cleaning the graphite parts with the brushes. In summary, this technical solution achieves automated cleaning of graphite parts on the furnace roof, significantly shortening the cleaning cycle and meeting the nuclear industry's requirements for efficient equipment operation. Using brushes to clean graphite parts does not cause chemical corrosion and can extend their service life.
[0009] Furthermore, to ensure the stability of the graphite parts during the picking and placing process, thereby facilitating the smooth operation of the picking and placing work, the lower end face of the turntable is provided with multiple positioning posts. The pushing cylinder assembly and the positioning cylinder assembly are both located below the turntable. The pushing cylinder assembly includes a pushing cylinder, a fixed push plate, and an elastic push plate. The fixed push plate is mounted on the drive rod of the pushing cylinder. The fixed push plate has an opening slot on the side near the positioning post. The elastic push plate is rotatably mounted in the opening slot. The rotation axis of the elastic push plate is perpendicular to the extension direction of the drive rod. A limiting block is provided behind the opening slot. During the extension of the drive rod of the pushing cylinder, the elastic push plate pushes the positioning post in front of it. During the retraction of the drive rod of the pushing cylinder, the elastic push plate avoids the positioning post behind it.
[0010] The positioning cylinder assembly includes a positioning cylinder and a V-shaped positioning head disposed at the end of the positioning cylinder. When the positioning cylinder extends, it drives the V-shaped positioning head to move toward the corresponding positioning post until the V-shaped opening of the V-shaped positioning head abuts against the positioning post.
[0011] Furthermore, to better drive and lock the turntable, the angle between the first positioning post facing the positioning cylinder assembly and the second positioning post in front of the elastic push plate is 90 degrees. The positioning cylinder assembly and the push cylinder assembly work together to ensure the turntable's rotation angle is precise.
[0012] Furthermore, it also includes a balancing assembly, which comprises a support plate, a rack assembly, and a sprocket assembly. The rack assembly includes four vertical racks spaced apart on the brush support plate, the vertical racks penetrating the support plate. Gears are provided on the support plate opposite to the racks, and the gears mesh with the vertical racks. Two gears on the same side are fixed on the same drive shaft, which is mounted on the support plate via a bearing seat. A first sprocket and a second sprocket are respectively provided on the two drive shafts, and a chain is provided between the first sprocket and the second sprocket.
[0013] During the lifting and lowering of the brush support plate, the synchronous transmission of the rack and pinion assembly and the sprocket assembly can maintain the balance of lifting and lowering, prevent the equipment from becoming unstable due to the shift of the center of gravity, and ensure the stability and safety of the cleaning process.
[0014] Furthermore, in order to improve the smoothness of the lifting action, the guide assembly includes a guide sleeve and a vertical guide shaft. The guide sleeve is mounted on the support plate, and the lower end of the vertical guide shaft is fixedly connected to the brush support plate. The vertical guide shaft and the guide sleeve are slidably engaged.
[0015] Furthermore, there are two support plates spaced apart. The brush drive motor is located outside the vertical projection area of the support plate. Multiple polyurethane rods are provided at the upper end of the brush support plate, and these rods are located within the vertical projection area of the support plate. When the brush support plate drives the brush drive motor upwards, the portion of the brush drive motor that is higher will avoid the support plate above it, and the polyurethane rods will avoid hard contact.
[0016] Furthermore, in order to better drive the brush body, the brush assembly includes a rotating shaft and a brush body. The brush drive motor is connected to the rotating shaft for transmission. The brush body is located at the lower end of the rotating shaft and is used to clean tubular or plate-shaped graphite parts.
[0017] Furthermore, to achieve a more comprehensive cleaning effect for different graphite parts, the brush body for cleaning tubular graphite parts includes vertically arranged outer and inner brushes. The outer brush is used to clean the outer wall of the tubular graphite part, and the inner brush is used to clean the inner wall of the tubular graphite part. The vertical length of the outer and inner brushes matches the depth of the tubular graphite part. The brush body for cleaning plate-shaped graphite parts includes a horizontal brush. The horizontal brush cleans the upper surface of the plate-shaped graphite part, and the horizontal length of the horizontal brush matches the width of the plate-shaped graphite part.
[0018] Furthermore, to better position different graphite parts, the positioning fixture includes multiple circumferentially evenly arranged support feet. Each support foot is equipped with a positioning ring, and each positioning ring contains an annular positioning groove. The annular positioning groove is respectively matched to the dimensions of the graphite cylinder, exhaust pipe, graphite cover, dustproof graphite tube, and graphite cone. The positioning fixture is customized according to the shape of the graphite parts, enabling precise positioning and ensuring accurate cleaning.
[0019] Furthermore, the system also includes a cabinet body with a door assembly. This door assembly comprises a drive cylinder, a door panel, and vertical guide rails. The vertical guide rails are symmetrically arranged at the cabinet doors. The drive cylinder drives the door panel to move up and down along the vertical guide rails. Specifically, the drive cylinder drives the door panel to move up and down along the vertical guide rails, achieving smooth lifting and lowering of the cabinet door. It should be noted that the cabinet door has a downward pressing action when it descends to the bottom, thereby ensuring a seal within the cabinet. This downward pressing action can be achieved using existing technology, and the specific structure will not be elaborated further.
[0020] The beneficial effects of this utility model are as follows: In this technical solution, because the turntable is circumferentially spaced with multiple positioning fixtures, these fixtures can define the positions of multiple graphite parts. Because the positioning cylinder assembly locks the turntable's rotation position, it maintains the stability of the turntable during the cleaning process of the graphite parts, thus preventing the graphite parts from shifting during subsequent cleaning and affecting the cleaning effect. Furthermore, because the cylinder assembly drives the turntable to rotate, during the picking and placing of graphite parts, the multiple positioning fixtures can be rotated sequentially to the picking and placing station, thereby facilitating the picking and placing of graphite parts from the picking and placing station. Because the cylinder assembly drives the brush support plate to rise and fall, and the guide assembly guides the rise and fall of the brush support plate, the cylinder assembly, in conjunction with the guide assembly, ensures the smoothness of the rise and fall of the brush support plate. This also allows the brush drive motor mounted on the brush support plate, and the brush assembly driven by the brush drive motor, to rise and fall smoothly. The brush assembly rises when parts need to be picked up or placed, and falls when the placed graphite parts need to be cleaned. The brush drive motor then rotates the brush assembly, thus cleaning the graphite parts with the brushes. In summary, this technical solution achieves automated cleaning of graphite parts on the furnace roof, significantly shortening the cleaning cycle and meeting the nuclear industry's requirements for efficient equipment operation. Using brushes to clean graphite parts does not cause chemical corrosion and can extend their service life. Attached Figure Description

Detailed Implementation
[0035] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0036] Example 1:
[0037] like Figures 1-13As shown, this embodiment provides a graphite part cleaning device, including a turntable assembly and a lifting brush assembly. The turntable assembly includes a turntable 1, a push cylinder assembly and a positioning cylinder assembly. The push cylinder assembly drives the turntable 1 to rotate, and the positioning cylinder assembly locks the rotation position of the turntable 1. The turntable 1 is provided with a plurality of positioning fixtures 2 at intervals around the circumference. The positioning fixtures 2 are used to position the graphite part 3.
[0038] The lifting brush assembly includes a cylinder assembly 37, a brush support plate 4, a guide assembly, a brush drive motor 5, and a brush assembly 6. The cylinder assembly 37 drives the brush support plate 4 to move up and down. The guide assembly provides guidance for the up and down movement of the brush support plate 4. The brush drive motor 5 is mounted on the brush support plate 4. The brush assembly 6 is located below the brush support plate 4. Multiple brush assemblies 6 correspond one-to-one with the positions of multiple positioning fixtures 2. The brush drive motor 5 drives the brush assembly 6 to rotate and clean the graphite parts 3 on the positioning fixtures 2.
[0039] In this technical solution, multiple positioning fixtures 2 are spaced circumferentially on the turntable 1. These fixtures can define the positions of multiple graphite parts 3. Because the positioning cylinder assembly locks the rotation position of the turntable 1, it maintains the stability of the turntable 1 during the cleaning of the graphite parts 3, preventing the position of the graphite parts 3 from shifting during subsequent cleaning and affecting the cleaning effect. Since the cylinder assembly drives the turntable 1 to rotate, during the picking and placing of graphite parts 3, the multiple positioning fixtures 2 can be rotated sequentially to the picking and placing station, thus facilitating the picking and placing of graphite parts 3 from the picking and placing station. Because the cylinder assembly 37 drives the brush support plate 4 to move up and down, and the guide assembly provides guidance for the movement of the brush support plate 4, the cylinder assembly 37, in conjunction with the guide assembly, ensures the smooth movement of the brush support plate 4. This also allows the brush drive motor 5 mounted on the brush support plate 4, and the brush assembly 6 driven by the brush drive motor 5, to move up and down smoothly. The brush assembly 6 rises when it is necessary to pick up or place parts, and descends when it is necessary to clean the placed graphite part 3. The brush drive motor 5 then drives the brush assembly 6 to rotate, thereby cleaning the graphite part 3 with the brush. In summary, this technical solution achieves automated cleaning of the graphite part 3 on the furnace roof, significantly shortening the cleaning cycle and meeting the nuclear industry's requirements for efficient equipment operation. Using a brush to clean the graphite part 3 does not cause chemical corrosion and can extend its service life.
[0040] Example 2:
[0041] This embodiment is an optimization based on the above embodiment 1.
[0042] like Figures 3-9As shown, in order to keep the graphite part 3 stable during the picking and placing process, thus facilitating the smooth operation of picking and placing parts, the lower end face of the turntable 1 is provided with multiple positioning posts 7. The pushing cylinder assembly and the positioning cylinder assembly are both located below the turntable 1. The pushing cylinder assembly includes a pushing cylinder 8, a fixed push plate 9, and an elastic push plate 10. The fixed push plate 9 is mounted on the drive rod of the pushing cylinder 8. The side of the fixed push plate 9 near the positioning posts 7 is provided with an opening groove 11. The elastic push plate 10 is rotatably mounted in the opening groove 11. The rotation axis of the elastic push plate 10 is perpendicular to the extension direction of the drive rod. A limiting block 12 is provided behind the groove 11. The limiting block 12 can also be integrally formed on the fixed push plate 9. During the extension of the drive rod of the cylinder 8, the elastic push plate 10 pushes the positioning post 7 located in front of it. During the retraction of the drive rod of the cylinder 8, the elastic push plate 10 avoids the positioning post 7 located behind it. Specifically, the elastic push plate 10 includes a movable push plate 10.1 and a torsion spring 10.2. The movable push plate 10.1 is rotatably connected to the fixed push plate 9 through a pin 13. The torsion spring 10.2 is sleeved on the pin 13 so that the movable push plate 10.1 can be reset after rotation.
[0043] The positioning cylinder assembly includes a positioning cylinder 14 and a V-shaped positioning head 15 disposed at the end of the positioning cylinder 14. When the positioning cylinder 14 extends, it drives the V-shaped positioning head 15 to move toward the corresponding positioning post 7 until the V-shaped opening 16 of the V-shaped positioning head 15 abuts against the positioning post 7.
[0044] Specifically, the cylinder 8 drives the fixed push plate 9 to move forward. The elastic push plate 10 on the fixed push plate 9 pushes the positioning post 7 in front of it and drives the turntable 1 to rotate. In this step, the limiting block 12 set behind the opening slot 11 can keep the elastic push plate 10 stable during the process of pushing the positioning post 7 forward. After the turntable 1 completes one rotation (the positioning post 7 is located in the position directly opposite the V-shaped positioning head 15), the positioning cylinder 14 is started. The positioning cylinder 14 extends and drives the V-shaped positioning head 15 to move toward the corresponding positioning post 7 until the V-shaped opening 16 of the V-shaped positioning head 15 abuts against the positioning post 7, thereby locking the turntable 1 after one rotation. This stabilizes the position of the graphite part 3 located at the part picking and placing station, so that the subsequent part picking and placing work can proceed smoothly.
[0045] After one loading and unloading operation is completed, the next rotation drive is required. The V-shaped positioning head 15 remains in abutting position with the positioning post 7. Then, the push cylinder 8 drives the fixed push plate 9 to move backward. The rear end of the elastic push plate 10 abuts against the positioning post 7 located behind. When it continues to move backward, the positioning post 7 located behind pushes the elastic push plate 10 forward until the elastic push plate 10 disengages from the positioning post 7 behind and the positioning post 7 behind is located in front of the elastic push plate 10. Subsequently, the positioning post 7 located in front of the elastic push plate 10 can be pushed again. The positioning cylinder assembly needs to release the lock on the corresponding positioning post 7.
[0046] Example 3:
[0047] This embodiment is an optimization based on the above embodiment 2.
[0048] like Figure 3 As shown, to better drive and lock the turntable 1, the angle between the first positioning post 7.1 facing the positioning cylinder assembly and the second positioning post 7.2 in front of the elastic push plate 10 is 90 degrees. The positioning cylinder assembly and the push cylinder assembly work together to ensure the precise rotation angle of the turntable 1.
[0049] Example 4:
[0050] This embodiment is an optimization based on the above embodiment 1.
[0051] It also includes a balancing assembly, which includes a support plate 17, a rack assembly, and a sprocket assembly. The rack assembly includes four vertical racks 18 spaced apart on the brush support plate 4. The vertical racks 18 pass through the support plate 17. Gears 19 are provided on the support plate 17 at positions opposite to the racks. The gears 19 mesh with the vertical racks 18. Two gears 19 located on the same side are fixed on the same drive shaft 20. The drive shaft 20 is mounted on the support plate 17 through a bearing seat 21. A first sprocket 22 and a second sprocket 23 are respectively provided on the two drive shafts 20. A chain 24 is provided between the first sprocket 22 and the second sprocket 23.
[0052] During the lifting and lowering of the brush support plate 4, the synchronous transmission of the rack and pinion assembly and the sprocket assembly maintains the balance of lifting and lowering, preventing instability caused by a shift in the center of gravity and ensuring the stability and safety of the cleaning process. Specifically, an intermediate sprocket 25 can be installed on the support plate 17, which meshes with the chain 24. Four cylinder assemblies 37 are fixedly installed on the support plate 17. The drive rods of the cylinder assemblies 37 extend out of the support plate 17 and connect to the brush support plate 4, thereby driving the brush support plate 4 to lift and lower.
[0053] Example 5:
[0054] This embodiment is an optimization based on the above embodiment 1.
[0055] In order to improve the smoothness of the lifting action, the guide assembly includes a guide sleeve 26 and a vertical guide shaft 27. The guide sleeve 26 is set on the support plate 17, and the lower end of the vertical guide shaft 27 is fixedly connected to the brush support plate 4. The vertical guide shaft 27 and the guide sleeve 26 are in sliding cooperation.
[0056] Example 6:
[0057] This embodiment is an optimization based on the above embodiment 4.
[0058] There are two support plates 17, spaced apart. The brush drive motor 5 is located outside the vertical projection area of the support plate 17. Multiple polyurethane rods 28 are located at the upper end of the brush support plate 4, within the vertical projection area of the support plate 17. When the brush support plate 4 drives the brush drive motor 5 to rise vertically, the higher portion of the brush drive motor 5 will avoid the support plate 17 above it, and the polyurethane rods 28 will avoid hard contact.
[0059] Example 7:
[0060] This embodiment is an optimization based on the above embodiment 1.
[0061] To better drive the brush body, the brush assembly 6 includes a rotating shaft 29 and a brush body. The brush drive motor 5 is connected to the rotating shaft 29 for transmission. The brush body is located at the lower end of the rotating shaft 29 and is used to clean tubular or plate-shaped graphite parts.
[0062] Example 8:
[0063] This embodiment is an optimization based on the above embodiment 7.
[0064] To achieve a more comprehensive cleaning effect for different graphite parts 3, the brush body for cleaning tubular graphite parts includes a vertically arranged outer brush 30 and an inner brush 31. The spacing between the outer brush 30 and the inner brush 31 is adjustable. The outer brush 30 is used to clean the outer wall of the tubular graphite part, and the inner brush 31 is used to clean the inner wall of the tubular graphite part. The vertical length of the outer brush 30 and the inner brush 31 matches the depth of the tubular graphite part. The brush body for cleaning plate-shaped graphite parts includes a horizontal brush 32. The horizontal brush 32 cleans the upper surface of the plate-shaped graphite part. The horizontal length of the horizontal brush 32 matches the width of the plate-shaped graphite part 3.
[0065] Specifically, for larger tubular graphite parts, two sets of outer brushes 30 and inner brushes 31 can be symmetrically arranged.
[0066] Example 9:
[0067] This embodiment is an optimization based on the above embodiment 1.
[0068] like Figure 11As shown, to better position different graphite parts 3, the positioning fixture 2 includes multiple circumferentially evenly arranged support feet 2.1. Each support foot 2.1 has a positioning ring 2.2, and the positioning ring 2.2 has an annular positioning groove 2.3. The annular positioning groove 2.3 is matched to the dimensions of the graphite cylinder, exhaust pipe, graphite cover, dustproof graphite tube, and graphite cone disk, respectively. The positioning fixture 2 is customized according to the shape of the graphite part 3, and can accurately position the graphite part 3, ensuring accurate cleaning.
[0069] Example 10:
[0070] This embodiment is an optimization based on the above embodiment 1.
[0071] like Figure 12 , Figure 13 As shown, the system also includes a cabinet body 35, on which a cabinet door assembly is mounted. The cabinet door assembly includes a drive cylinder 36, a door panel 33, and a vertical guide rail 34. The vertical guide rails 34 are symmetrically arranged at the cabinet doors. The drive cylinder 36 drives the door panel 33 to move up and down along the vertical guide rails 34, achieving smooth lifting and lowering of the cabinet door. It should be noted that the cabinet door has a downward pressing action when it descends to the bottom, thereby ensuring a tight seal inside the cabinet. This downward pressing action can be achieved using existing technology, and the specific structure will not be elaborated further. Under precise cylinder control, the cabinet door assembly lifts and lowers smoothly and seals tightly, improving operational safety.
[0072] This device can automate the cleaning of graphite parts 3 on the furnace top, improving production efficiency. The cleaning process is carried out in a closed cabinet, ensuring high operational safety. It can also interact and link with other automated equipment on the production line to achieve intelligent control of equipment storage and transfer links.
[0073] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
