Description

Technical Field

[0001] This invention relates to the field of turbine testing equipment technology, and more specifically, to a circulating heat treatment system for turbine testing. Background Technology

[0002] In turbine testing, cyclic heat treatment refers to the periodic heating and cooling process applied to turbine components. Cyclic heat treatment is typically used to ensure turbine parts maintain good performance under high temperature, high pressure, and high load operating conditions. This is crucial for improving turbine durability, fatigue resistance, and overall performance.

[0003] A heating furnace is used in the cyclic heat treatment of turbine components. The furnace performs the cyclic heat treatment, which includes steps such as heating, holding, and cooling. These heat treatment processes can change the crystal structure of turbine components, thereby improving their mechanical properties and durability.

[0004] Uneven temperature distribution can occur in heating furnaces, and since turbine components are typically fixed within the furnace and their positions remain unchanged, some areas of the components may experience excessively high or low temperatures. This can affect the effectiveness of heat treatment and prevent some components from achieving the desired performance improvement. Furthermore, under high-temperature conditions, surface flakes or peeling may occur, especially after rapid cooling following thermal expansion. This can lead to the formation of tiny particles or debris that adhere to the surface of the components. If not removed promptly, these particles or debris can increase the surface roughness of the turbine components, negatively impacting the turbine's aerodynamic performance. Therefore, it is necessary to propose a cyclic heat treatment system for turbine experiments to address these issues. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a cyclic heat treatment system for turbine experiments. This system solves the problems of uneven heating of turbine components due to uneven temperature distribution within the heating furnace and the fixed position of turbine parts, which affects the heat treatment effect. It also addresses the difficulty in timely removing particles or debris from the surface of turbine components caused by temperature changes. The system ensures that each turbine component receives the same heating environment and heating time, achieving better heat treatment results; simultaneously, it can promptly remove tiny particles and debris from the surface of turbine components, improving surface smoothness.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1-9 As shown, a cyclic heat treatment system for turbine experiments includes:

[0036] A heating furnace 1, wherein an ash receiving mechanism 3 for recycling impurities and debris is slidably connected inside the heating furnace 1, the ash receiving mechanism 3 includes an ash receiving box 31 and triangular plates 36, the ash receiving box 31 is slidably connected inside the heating furnace 1, and a plurality of triangular plates 36 are fixed at equal intervals above the ash receiving box 31.

[0037] Above the ash collection box 31, a rotary mechanism 4 for driving the parts to move in a circular motion is also installed. The rotary mechanism 4 includes a rotary belt 43, which is rotatably connected to the top of the ash collection box 31.

[0038] The top surface of the rotating belt 43 is equidistantly equipped with a dust-shaking mechanism 5 for fixing and driving the parts to shake. The dust-shaking mechanism 5 includes a column 51, a sliding column 53 and a roller 55. A plurality of columns 51 are installed on the top surface of the rotating belt 43. The sliding column 53 is slidably connected inside the column 51 and the sliding column 53 passes through the top end of the column 51. The bottom of the sliding column 53 is rotatably connected to the roller 55. The roller 55 is slidably connected to the inclined surface of the triangular plate 36.

[0039] The heating furnace 1 is also equipped with a blower mechanism 8 for uniformly heating the parts.

[0040] In a further embodiment, several processed parts 6 are mounted on the dust-removing mechanism 5 on the top surface of the rotary belt 43 and pushed together into the heating furnace 1 for heat treatment. Inside the heating furnace 1, the rotary belt 43 drives the several processed parts 6 to circulate at a uniform speed, thereby continuously changing the heating position of each processed part 6 to ensure uniform heating of the processed parts 6. At the same time, during the circulating motion of the processed parts 6, the blower mechanism 8 blows out hot air, which acts on each processed part 6, not only improving the heating efficiency of the processed parts 6, but also blowing off particles and debris and other impurities on the surface of the processed parts 6. During the uniform circulating motion of the processed parts 6, the roller 55 in the dust-removing mechanism 5 cooperates with the triangular plate 36. The roller 55 rises along the inclined surface of the triangular plate 36, thereby driving the dust-removing mechanism 5 to circulate. As the workpiece 6 rises, and the roller 55 passes the triangular plate 36, the sliding column 53 will cause the workpiece 6 to fall rapidly, impacting the bottom of the column 51. This impact force causes the workpiece 6 to vibrate, thereby shaking off particles and debris and other impurities from the surface of the workpiece 6, thus ensuring the cleanliness of the surface of each workpiece 6 and preventing the workpiece 6 from becoming rough due to impurities adhering to its surface after cooling, which would affect the processing quality. The shaken-off impurities eventually fall into the ash collection box 31 at the bottom of the heating furnace 1, and are later pulled out with the ash collection box 31, preventing them from scattering into the heating furnace 1.

[0041] Specifically, the heating furnace 1 is provided with a triggering mechanism 2, which includes a docking groove 21, a support plate 22, a spring groove 23, an adjusting spring 24, and an insertion post 25. The heating furnace 1 has docking grooves 21 on both sides inside. The outlet of the heating furnace 1 is equipped with the support plate 22 for receiving the ash receiving box 31. The end of the docking groove 21 is connected to the spring groove 23. The adjusting spring 24 is installed in the spring groove 23. The insertion post 25 is slidably connected to the inside of the spring groove 23.

[0042] In a further embodiment, the support plate 22 is used to support and place the ash receiving mechanism 3 after it is pulled out of the heating furnace 1; the triggering mechanism 2 can cooperate with the ash scraping mechanism 7 on both sides of the ash receiving box 31 to complete the function of the ash scraping mechanism 7 to collect particles and debris and other impurities, so as to facilitate subsequent cleaning operations by workers.

[0043] Specifically, the ash receiving mechanism 3 also includes a shelf 32, an outer slide 33, an inner slide 34, a stabilizing groove 35, and a pressing wedge 37. The shelf 32 is fixed on the top surface of the ash receiving box 31. The outer slide 33 is provided on both sides of the ash receiving box 31. The inner slide 34 and the stabilizing groove 35 are provided on the inner side of the ash receiving box 31 from top to bottom. The pressing wedge 37 is fixed inside the end of the outer slide 33 that extends into the heating furnace 1.

[0044] In a further embodiment, the main function of the ash receiving mechanism 3 is to collect the debris and other impurities generated during the heat treatment of the workpiece 6, preventing the impurities from falling into the heating furnace 1 and causing pollution and other problems. Secondly, the ash receiving mechanism 3 also provides support for other mechanisms and the workpiece 6, so that the workpiece 6 can rotate in the air inside the heating furnace 1. One side of the extrusion wedge 37 is an inclined surface, which cooperates with the contact wedge 79 to change the movement direction of the contact wedge 79 (the movement direction changes by 90 degrees), thereby driving the push plate 78 to slide.

[0045] Specifically, the rotary mechanism 4 further includes a rotary motor 41, a rotary gear 42, and a rotary toothed belt 44. The rotary motor 41 is mounted on the bottom surface of the shelf 32, the rotary gear 42 is fixed to the output end of the rotary motor 41, and the rotary toothed belt 44 is mounted on the bottom of the rotary belt 43, and the rotary toothed belt 44 is meshed with the rotary gear 42.

[0046] In a further embodiment, the rotary mechanism 4 can drive the ash-dispersing mechanism 5 to move in a uniform cycle within the heating furnace 1, thereby driving the processed part 6 to move in a uniform cycle, continuously changing the heating position of each processed part 6, ensuring uniform heating of the processed part 6, and improving the quality of heat treatment of the processed part 6.

[0047] Specifically, the dust-shaking mechanism 5 further includes a lifting groove 52, a lifting spring 54, a base 56, external support claws 57, and a pressure column 58. The lifting groove 52 is provided through the outer side of the column 51, and the roller 55 slides in the lifting groove 52. The lifting spring 54 is sleeved on the sliding column 53, and the two ends of the lifting spring 54 respectively abut against the inside of the column 51 and the bottom end of the sliding column 53. The base 56 is fixed to the top of the sliding column 53. Several external support claws 57 are rotatably connected to the top of the base 56 through a torsion spring, and the top end of the external support claws 57 has a barb-shaped structure. The bottom end of the pressure column 58 is threaded to the inside of the base 56.

[0048] In a further embodiment, the dust-shaking mechanism 5 not only serves to install and stably fix the workpiece 6, but also utilizes the cyclical motion of the rotary mechanism 4 to intermittently raise and lower the dust-shaking mechanism 5 (according to the attached instruction manual). Figure 2 (The same applies below) The impact force generated by the rapid descent of the dust-shaking mechanism 5 causes the workpiece 6 to vibrate violently, thereby shaking off the fragments and debris on the surface of the workpiece 6 and ensuring that the surface of the workpiece 6 remains clean. The outer support claw 57 swings outward and tightens the workpiece 6. The barb at the top of the outer support claw 57 can hook onto the top surface of the workpiece 6, thereby more firmly restricting the workpiece 6 and preventing the workpiece 6 from loosening due to frequent vibration.

[0049] Specifically, in its natural state, the torsion spring will cause all the outer support claws 57 to converge toward the center, and the pressure column 58 is located at the center surrounded by all the outer support claws 57 and abuts against the outer support claws 57. The pressure column 58 is a frustum-shaped structure with a larger diameter at the top and a smaller diameter at the bottom.

[0050] In a further embodiment, when there is no pressure from the pressure column 58, the external support claws 57 connected to the top surface of the base 56 by the torsion spring will stop at the center of the external support claws 57, thereby reducing the top diameter of the base 56 and making it easier to install the workpiece 6 on the base 56. The conical frustum structure of the pressure column 58 can exert greater pressure on the external support claws 57 as the pressure column 58 descends, thereby fixing the workpiece 6 more efficiently.

[0051] Specifically, the ash receiving box 31 is further equipped with a ash scraping mechanism 7. The ash scraping mechanism 7 includes a transmission belt 71, a scraper 72, a connecting rod 73, a slide cylinder 74, a docking platform 75, a separation notch 76, a return spring 77, a push plate 78, and an abutment wedge 79. The transmission belt 71 is slidably connected to the inside of both sides of the ash receiving box 31. The scraper 72 is slidably connected to the inside of the ash receiving box 31. Four connecting rods 73 are symmetrically fixed on both sides of the scraper 72, and two connecting rods 73 on each side are slidably connected to the inside of the inner slide groove 34 and the stabilizing groove 35 on the corresponding side. The connecting rods 73 in the inner slide groove 34 are fixed to the transmission belt 71, and the slide cylinder 74 is slidably connected to the outer... The slide 74 is fixed to the transmission belt 71 inside the slide groove 33. The docking platform 75 is fixed to the outer end of the slide 74 and is slidably connected to the corresponding docking groove 21. The separation notch 76 is provided through one side of the docking platform 75 and the width of the separation notch 76 is equal to the diameter of the insertion post 25. The return spring 77 is installed inside the slide 74. The push plate 78 is installed at the end of the return spring 77 and is slidably connected to the inside of the slide 74. The abutment wedge 79 is fixed to the side of the push plate 78 and the abutment wedge 79 penetrates the side of the slide 74 and cooperates with the compression wedge 37.

[0052] In a further embodiment, the ash scraping mechanism 7 is installed inside the ash receiving box 31. When the ash receiving box 31 is pushed into the heating furnace 1, it is connected to the ash scraping mechanism 7 through the triggering mechanism 2. As the ash receiving box 31 goes deeper, the scraper 72 is finally moved to the innermost end of the ash receiving box 31 (the end that goes deeper into the heating furnace 1 is defined as the inner end, the same below). During the process of pulling out the ash receiving box 31, the scraper 72 is driven to slide to the outer end of the ash receiving box 31 through the cooperation of the triggering mechanism 2 and the ash scraping mechanism 7. The sliding of the scraper 72 will scrape off and push the impurities in the ash receiving box 31, and collect the impurities at the outer end of the ash receiving box 31, which is convenient for workers to carry out cleaning operations.

[0053] Specifically, the outer slide groove 33 and the inner slide groove 34 have the same length, and the vertical distance between the slide cylinder 74 and the scraper 72 is approximately equal to the length of the outer slide groove 33 or the inner slide groove 34.

[0054] In a further embodiment, in order to ensure that when the scraper 72 is at one end of the ash receiving box 31, the slide 74 and other related structures are exactly at the other end of the outer slide groove 33.

[0055] Specifically, the blower mechanism 8 includes a hot air pipe 81 and blower nozzles 82. The hot air pipe 81 is installed on the inner top surface of the heating furnace 1, and a plurality of blower nozzles 82 are evenly distributed at the bottom of the hot air pipe 81.

[0056] In a further embodiment, a high-temperature airflow generated by the heating furnace 1 is introduced into the hot air pipe 81 and blown onto each cyclically moving workpiece 6 through the blower nozzle 82. This not only improves the heating efficiency of the workpiece 6, but also blows off impurities such as particles and fragments from the surface of the workpiece 6.

[0057] Working principle and usage process of this invention:

[0058] Initially, the slide cylinder 74 and related structures are located at the inner end of the outer slide groove 33, and the scraper 72 is located at the inner outer end of the ash receiving box 31. First, the workpiece 6 is installed on each base 56, which supports the workpiece 6, allowing the outer support claw 57 to pass through the workpiece 6. Then, the pressure column 58 is pressed down, which opens the outer support claw 57 and connects it with the thread inside the base 56. As the pressure column 58 is rotated, its connection with the base 56 becomes tighter, and the outer support claw 57 is gradually squeezed outward by the pressure column 58. The outer support claw 57 presses the workpiece 6 tightly, and the barb at the top of the outer support claw 57 simultaneously restricts the top surface of the workpiece 6, improving stability. Then, when the ash receiving box 31 is pushed into the heating furnace 1, the docking platform 75 at the outer end of the slide cylinder 74 slides into the docking groove 21, and the inclined outer edge of the docking platform 75 easily presses the insertion post 25 at the outer end of the docking groove 21, causing the insertion post 25 to slide into the spring groove 23. At the same time, the adjusting spring 24 is compressed, and the contraction of the insertion post 25 makes the docking platform 75 move easily. When the docking platform 75 docks with the insertion post 25, the adjusting spring 24 pushes the insertion post 25 into the docking platform 75 and the slide cylinder 74, so that the slide cylinder 74 and the insertion post 25 are connected. During this process, the insertion post 25 pushes... Inside the sliding cylinder 74, the pusher 78 compresses the return spring 77, and then the ash receiving box 31 continues to penetrate deeper into the heating furnace 1. The insertion column 25 fixes the sliding cylinder 74, which slides relative to the outer sliding groove 33. The fixation of the sliding cylinder 74 will drive the transmission belt 71 to rotate in the ash receiving box 31, thereby driving the scraper 72 to slide. The connecting rods 73 on both sides of the scraper 72 slide in the inner sliding groove 34 and the stabilizing groove 35 on the inner side of the ash receiving box 31, respectively. When the ash receiving box 31 is completely inside the heating furnace 1, the sliding cylinder 74 stops at the outer end of the outer sliding groove 33, and the scraper 72 is exactly at the inner end of the ash receiving box 31. During the heat treatment process, the rotary motor 41 drives the rotary belt 43 to rotate cyclically through the meshing of the rotary gear 42 and the rotary toothed belt 44. The rotary belt 43 drives the dust-shaking mechanism 5 and the workpiece 6 to move cyclically at a uniform speed. During the rotation, the roller 55 rolls upward from the bottom of the inclined surface of the triangular plate 36, which is spaced apart on the outside of the shelf 32. The roller 55 rises and drives the slide column 53 to slide upward in the column 51, compressing the lifting spring 54. At the same time, the slide column 53 drives the workpiece 6 to rise through the base 56. When the roller 55 moves to the top of the inclined surface of the triangular plate 36 and then disengages from the triangular plate 36, the slide column 53 drives the workpiece 6 to fall rapidly under the action of gravity and the push of the lifting spring 54. The slide column 53 hits the bottom of the column 51, and the impact force causes the workpiece 6 to vibrate, thereby shaking off the fragments and debris on the surface of the workpiece 6. During this process, the hot air pipe 81 continuously introduces the high-temperature airflow generated by the heating furnace 1, which is blown onto each cyclically moving workpiece 6 through the blower nozzle 82. After undergoing heating, heat preservation and cooling processes in the heating furnace 1, the processed part 6 will be pulled out together with the ash receiving mechanism 3 after completing the heat treatment.During the process of pulling out the ash collection box 31, the slide cylinder 74, which is fixed by the insertion post 25, slides relative to the inner end of the outward slide groove 33, causing the scraper 72 at the inner end of the ash collection box 31 to slide outward (this movement process is the same as the movement method described above, and will not be repeated here). The scraper 72 scrapes and collects the fragments and debris in the ash collection box 31, and finally, the ash collection box 31 is completely pulled out. When the slide cylinder 74 reaches the inner end of the outer slide groove 33, the pressing wedge 37 is inserted into the interior of the slide cylinder 74 and cooperates with the abutting wedge 79, thereby pushing the abutting wedge 79 to move. The abutting wedge 79 drives the push plate 78 to slide, pushing the docking point into the spring groove 23. At the same time, the reset spring 77 is reset and the adjusting spring 24 is compressed. When the push plate 78 pushes the insertion post 25 to the same depth as the separation notch 76 on the side of the slide cylinder 74, the insertion post 25 can be easily separated from the slide cylinder 74, thereby releasing the connection between the insertion post 25 and the slide cylinder 74, and finally achieving the purpose of completely pulling the ash collection box 31 out of the heating furnace 1.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
