Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, specifically to a heat treatment device for seamless stainless steel pipes. Background Technology

[0002] In the field of stainless steel pipe processing and manufacturing, stainless steel pipe fittings are the core components of pipeline systems. Their heat treatment process is crucial for improving the core mechanical properties of the products, such as tensile strength and corrosion resistance, as well as extending their overall service life.

[0003] For relatively short stainless steel pipe fittings, the commonly used heat treatment method in the prior art is to place multiple stainless steel pipe fittings together in the same material basket, and then immerse the material basket along with the internal pipe fittings into a heat treatment tank. The overall heat treatment operation is completed through the thermal action of the heat treatment medium in the tank. This method is simple to operate, can meet the basic requirements of batch processing, and has certain application value in small and medium-sized processing scenarios.

[0004] However, the above-mentioned treatment method still has certain limitations in practical applications. Since the pipes inside the material basket are in a natural stacking state, local stacking and mutual covering are likely to occur. This will affect the full contact between the heat treatment medium and the surface of the pipes to a certain extent, resulting in differences in the degree of heating of pipes in different positions. The heat treatment effect of some pipes is difficult to achieve the ideal state, which in turn affects the consistency of the performance of the finished pipes. Therefore, we propose a seamless stainless steel pipe heat treatment equipment. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a seamless stainless steel pipe heat treatment device, comprising a frame, the frame being a hollow cylindrical structure, a partition coaxially disposed inside the frame, a connecting frame disposed between the inner wall of the frame and the outer wall of the partition, gaps being reserved between the top of the partition and the top of the frame, and between the bottom of the partition and the bottom of the frame, a rotating shaft coaxially passing through the partition, a spiral blade fixedly sleeved on the outer wall of the rotating shaft, the spiral blade extending axially along the rotating shaft, a stirring assembly installed at the bottom of the outer wall of the rotating shaft, a disturbance assembly installed at the top of the outer wall of the rotating shaft, a detachable cover disposed at the top of the frame, and a detachable base plate disposed at the bottom of the frame.

[0006] In some embodiments, the shroud is a hollow conical structure with the smaller end facing down and the larger end facing up, and the outer periphery of the helical blades is adapted to the inner wall profile of the shroud.

[0009] In some embodiments, the disturbance component includes a connecting rod and a disturbance block. The connecting rod is fixed to the top of the side wall of the rotating shaft, and a spherical disturbance block is fixed to the end of the connecting rod away from the rotating shaft. The disturbance block is disposed between the guide plate and the frame, and an movable gap is reserved between the disturbance block and the outer wall of the guide plate and the inner wall of the frame.

[0010] In some embodiments, the inner wall of the shroud is provided with a plurality of sets of mounting grooves evenly distributed along its circumference, and each set of mounting grooves is provided with a detachable cleaning component, wherein the cleaning component and the mounting groove are in clearance fit.

[0011] In some embodiments, the cleaning assembly includes a mounting plate and a cleaning brush. The mounting plate is adapted to the contour of a mounting groove and inserted into the mounting groove. The cleaning brush is fixed to the side wall of the mounting plate. Fasteners are also installed between the mounting plate and the mounting groove.

[0012] In some embodiments, a rotating handle is installed through the center of the cover, and a rotating rod is coaxially fixedly connected to the bottom end of the rotating handle. The bottom end of the rotating rod extends to the bottom of the cover and is detachably connected to the top end of the rotating shaft through a snap-fit ​​assembly. A bearing is provided between the rotating handle and the cover to enable the rotating handle to rotate freely relative to the cover.

[0013] In some embodiments, the snap-fit ​​assembly includes a slot formed on the top end face of the rotating shaft and a snap-fit ​​block fixed to the bottom end of the rotating rod. The slot is a concave polygonal prism structure, and the snap-fit ​​block is a convex polygonal prism structure. The inner contour of the slot matches the outer contour of the snap-fit ​​block, thereby realizing circumferential limiting transmission between the two.

[0014] In some embodiments, multiple sets of mounting buckles are evenly connected circumferentially between the top edge of the cover and the frame, and between the bottom plate and the bottom edge of the frame, so that the cover, bottom plate and frame can be detachably fixed; the frame, cover, bottom plate and partition are all hollow structures.

Detailed Implementation

[0018] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-5 This invention provides a technical solution for a heat treatment device for seamless stainless steel pipes: A heat treatment device for seamless stainless steel pipes includes a frame 1, which is a hollow cylindrical structure. A partition 2 is coaxially arranged inside the frame 1. A connecting frame 3 is provided between the inner wall of the frame 1 and the outer wall of the partition 2. Gaps are reserved between the top of the partition 2 and the top of the frame 1, and between the bottom of the partition 2 and the bottom of the frame 1. A rotating shaft 4 is coaxially inserted inside the partition 2. A spiral blade 5 is fixedly sleeved on the outer wall of the rotating shaft 4. The spiral blade 5 extends along the axial direction of the rotating shaft 4. A stirring component is installed at the bottom of the outer wall of the rotating shaft 4, and a disturbance component is installed at the top of the outer wall of the rotating shaft 4. A cover 14 is detachably provided at the top of the frame 1, and a bottom plate 19 is detachably provided at the bottom of the frame 1.

[0020] The diaphragm 2 is a hollow conical structure with the small end facing down and the large end facing up, and the outer contour of the spiral blade 5 is adapted to the inner wall contour of the diaphragm 2.

[0021] An inclined guide plate 9 is fixedly connected to the top of the outer wall of the diaphragm 2. The guide plate 9 is inclined downward in the direction away from the diaphragm 2.

[0022] The stirring assembly includes multiple sets of stirring blades 6 evenly distributed around the circumference of the rotating shaft 4. The multiple sets of stirring blades 6 are fixed to the bottom of the side wall of the rotating shaft 4, and the edges of each stirring blade 6 are all treated with rounded transition.

[0023] The disturbance component includes a connecting rod 7 and a disturbance block 8. The connecting rod 7 is fixed to the top of the side wall of the rotating shaft 4. A spherical disturbance block 8 is fixed to the end of the connecting rod 7 away from the rotating shaft 4. The disturbance block 8 is set between the guide plate 9 and the frame 1, and there are reserved movable gaps between the disturbance block 8 and the outer wall of the guide plate 9 and the inner wall of the frame 1.

[0024] When in use, open the detachable cover 14 at the top of the frame 1, put the stainless steel pipe workpiece to be processed into the internal cavity of the frame 1, and close the cover 14 after feeding is completed; then, use hoisting equipment to put the entire frame 1 into the heat treatment tank to carry out the heat treatment operation of the stainless steel pipe.

[0025] The hollow cylindrical frame 1 has a regular and symmetrical structure, which can provide sufficient and balanced movement space for the internal stainless steel tube workpieces to circulate, reducing local jamming during the movement of the workpieces; at the same time, the cylindrical structure is evenly stressed, which can reduce the risk of deformation caused by uneven stress during hoisting, transportation and immersion in the heat treatment tank, and improve the structural stability and durability of the equipment.

[0026] During the heat treatment process, the rotating shaft 4, which is coaxially inserted inside the diaphragm 2, rotates synchronously. The rotating shaft 4 drives the spiral blades 5, which are fixedly sleeved on its outer wall, to rotate synchronously. Because the outer contour of the spiral blades 5 matches the inner wall contour of the diaphragm 2, and the diaphragm 2 is a hollow cone structure with the small end facing down and the large end facing up, the rotating spiral blades 5 can transport the stainless steel tube workpieces gathered at the center of the small end at the bottom of the diaphragm 2 upwards, so that a material flow gap is formed at the bottom of the diaphragm 2. The stainless steel tube workpieces inside the frame 1 and outside the diaphragm 2 are then replenished to this gap in time. After the workpieces are transported upwards by the spiral blades 5 to the large end at the top of the diaphragm 2, they emerge upwards and slide down the inclined slope of the guide plate 9, which is fixedly connected to the top of the outer wall of the diaphragm 2 and tilts downwards away from the diaphragm 2, to the upper area outside the diaphragm 2 under the guidance of the guide plate 9. This forms a circulating tumbling flow trajectory of the stainless steel tube workpieces inside the frame 1 from top to bottom and from inside to outside.

[0027] This circulating flow method can avoid the situation where stainless steel pipes are piled up inside the frame 1 and cover each other, allowing the outer wall of the stainless steel pipe to fully and evenly contact the medium in the heat treatment tank. This effectively ensures that the heat treatment temperature of all pipes is consistent and the heating is uniform, greatly improving the overall quality and performance consistency of the stainless steel pipes after heat treatment, and eliminating problems such as pipe deformation and substandard performance caused by insufficient or overheated local heating.

[0028] At the same time, during the rotation of the rotating shaft 4, the stirring component at the bottom of its outer wall and the disturbance component at the top of its outer wall will rotate synchronously. Multiple sets of stirring blades 6 at the bottom of the rotating shaft 4 are evenly distributed around the circumference of the rotating shaft 4. When rotating, they can fully stir the workpieces at the bottom of the frame 1 and the outside of the diaphragm 2, effectively separating and dispersing the stainless steel pipes that are piled up and stuck together. This not only avoids the pipes from getting blocked at the feed position at the small opening at the bottom of the diaphragm 2, but also further disperses the material pile, helping to improve the uniformity of the workpiece's heating. In addition, the edges of the stirring blades 6 are rounded to avoid scratching the wall of the stainless steel pipe during the stirring process, ensuring the integrity of the pipe's appearance.

[0029] The spherical disturbance block 8 at the top of the rotating shaft 4 rotates with the connecting rod 7 and makes circular motion in the gap between the outer wall of the guide plate 9 and the inner wall of the frame 1. The disturbance block 8 has a reserved movable gap between itself and the outer wall of the guide plate 9 and the inner wall of the frame 1. On the one hand, it can perform secondary disturbance and dispersion on the workpieces that slide down through the guide plate 9, preventing the workpieces from accumulating and jamming in the gap between the guide plate 9 and the frame 1, ensuring that the workpieces fall smoothly and avoiding blockage problems during the falling process. On the other hand, the spherical disturbance block 8 has no sharp edges and will not cause bumps or scratches when it comes into contact with the pipe fittings. At the same time, the disturbance force generated by its rotation can further drive the workpieces on the upper part of the frame 1 to flow, helping to accelerate the overall material circulation efficiency.

[0030] The shroud 2 adopts a hollow conical structure with the small end facing down and the large end facing up. Its conical inner wall structure not only matches the conveying trajectory of the spiral blade 5, making the upward conveying of the workpiece smoother and without jamming, but also forms a gathering guide for the upward conveying of the workpiece. Combined with the downward tilting guide of the guide plate 9, it helps to achieve the technical effect of smooth material conveying without blockage or jamming, and the workpiece being fully and evenly heated without bumps or scratches.

[0031] Example 2: Please refer to Figures 1-6 The present invention provides a technical solution for a heat treatment equipment for seamless stainless steel pipes: a heat treatment equipment for seamless stainless steel pipes, which further includes multiple sets of installation grooves 10 evenly opened along the circumference of the inner wall of the partition 2, and a detachable cleaning component is correspondingly provided in each set of installation grooves 10, and the cleaning component and the installation groove 10 are in clearance fit.

[0032] The cleaning assembly includes a mounting plate 11 and a cleaning brush 12. The mounting plate 11 is adapted to the contour of the mounting groove 10 and inserted into the mounting groove 10. The cleaning brush 12 is fixed to the side wall of the mounting plate 11. Fasteners 13 are also installed between the mounting plate 11 and the mounting groove 10. The bristles of the cleaning brush 12 are preferably made of high-temperature resistant ceramic fiber or high-silica glass fiber. This type of material can withstand high-temperature environments above 1000℃. At the same time, it is soft and its hardness is lower than that of stainless steel pipes. When cleaning by friction with the surface of the workpiece, it can effectively remove impurities from the surface of the pipe and avoid scratches or marks on the outer wall of the stainless steel pipe, thus ensuring the integrity of the pipe surface.

[0033] During use, as the stainless steel tube workpiece moves upward inside the diaphragm 2 with the rotation of the spiral blades 5, the cleaning brushes 12, which are evenly distributed around the inner wall of the diaphragm 2, can fully contact the outer wall of the workpiece. By using the contact friction generated by the movement of the workpiece, the dust and debris attached to the surface of the workpiece are cleaned. This reduces the number of impurities that adhere to the surface of the tube and participate in the heat treatment, which helps to improve the surface cleanliness and quality of the stainless steel tube after heat treatment. Meanwhile, multiple cleaning components are evenly distributed along the two circumferences of the cover, which can form a comprehensive contact cleaning of workpieces conveyed at different positions. With the circulation of the workpieces, the cleaning effect of each pipe can be kept relatively consistent.

[0034] The mounting plate 11 of the cleaning component is adapted to the contour of the mounting groove 10 on the inner wall of the cover 2 and is inserted into it. The cleaning component and the mounting groove 10 are in clearance fit, and the mounting plate 11 and the mounting groove 10 are reinforced by fasteners 13. This ensures that the cleaning component remains stable during the workpiece conveying process and is not prone to loosening or displacement. It also allows for easy unscrewing of the fasteners 13 and removal of the mounting plate 11 from the mounting groove 10 when the cleaning brush 12 is severely dirty or the bristles are worn, which affects the cleaning effect. The cleaning brush 12 can then be replaced or cleaned and maintained before being reinserted and fixed. The disassembly and assembly operations are simple and do not require disassembly of the entire equipment, which saves maintenance time and operating costs.

[0035] Example 3: Please refer to Figures 1-7 The present invention provides a technical solution for a heat treatment equipment for seamless stainless steel pipes: a heat treatment equipment for seamless stainless steel pipes, which further includes a rotating handle 15 installed through the center of a cover 14. A rotating rod 16 is coaxially fixedly connected to the bottom end of the rotating handle 15. The bottom end of the rotating rod 16 extends to the bottom of the cover 14 and is detachably connected to the top end of the rotating shaft 4 through a snap-fit ​​assembly. A bearing is provided between the rotating handle 15 and the cover 14 to realize the free rotation of the rotating handle 15 relative to the cover 14.

[0036] The snap-fit ​​assembly includes a snap-fit ​​groove 17 formed on the top end face of the rotating shaft 4 and a snap-fit ​​block 18 fixed to the bottom end of the rotating rod 16. The snap-fit ​​groove 17 is a concave polygonal prism structure, and the snap-fit ​​block 18 is a convex polygonal prism structure. The inner contour of the snap-fit ​​groove 17 is adapted to the outer contour of the snap-fit ​​block 18 to realize the circumferential limiting transmission of the two.

[0037] Multiple sets of mounting buckles 20 are evenly connected circumferentially between the top edge of the cover 14 and the frame 1, and between the bottom plate 19 and the bottom edge of the frame 1. The mounting buckles 20 enable the cover 14, the bottom plate 19 and the frame 1 to be detachably fixed. The frame 1, the cover 14, the bottom plate 19 and the partition 2 are all hollow structures.

[0038] During use, the rotating handle 15 is exposed above the cover 14. The driving method can be flexibly adapted according to actual needs. It can be manually rotated by holding the rotating handle 15, or a rotary motor can be installed on the hoisting equipment and connected to the rotating handle 15 to drive the rotating handle 15 to rotate. In order to reduce the surface scratches or deformation damage that may be caused by mutual squeezing and collision of stainless steel pipes during the accumulation inside the frame 1, the rotating handle 15 can be driven by periodically starting the drive structure. At the same time, the rotation speed of the rotating handle 15 is controlled to keep it smooth to avoid violent impact between pipes due to excessive speed. In this way, the slow rotation of the rotating shaft 4 drives the spiral blade 5, the stirring component and the disturbance component to operate synchronously, so as to achieve light stirring and dispersion of the pipes, which reduces the risk of squeezing damage between pipes and prepares the material for subsequent heat treatment operations.

[0039] The bearing between the rotating handle 15 and the cover 14 reduces rotational friction resistance, ensuring smooth rotation of the rotating handle 15. When the rotating handle 15 rotates, it drives the coaxial rotating rod 16 to rotate synchronously. With the help of the multi-faceted prism-shaped adapter of the locking block 18 at the bottom of the rotating rod 16 and the locking groove 17 at the top of the rotating shaft 4, a circumferential limiting transmission is formed, which can synchronously drive the rotating shaft 4 to rotate. This locking structure has stable transmission and is not prone to slippage. Moreover, the detachable locking method can quickly complete the separation and connection of the rotating rod 16 and the rotating shaft 4 when disassembling and assembling the cover 14, making the operation convenient.

[0040] Both the cover 14 and the base plate 19 are detachably fixed to the frame 1 by easy-to-disassemble mounting buckles 20. The disassembly and assembly operations are simple and labor-saving. When placing the workpiece to be processed into the frame 1 and when unloading the workpiece after heat treatment, there is no need to arrange the stainless steel pipes one by one. The feeding and unloading operations can be completed directly in batches, which effectively simplifies the loading and unloading operation steps, reduces the operation time, and improves the ease of use of the equipment and the overall heat treatment operation efficiency.

[0041] Meanwhile, the frame 1, cover 14, base plate 19, and partition 2 are all hollow structures. This hollow structure allows the heat treatment medium in the heat treatment tank to pass smoothly through the hollow areas of each component, contacting the stainless steel tube workpiece inside the frame 1 from multiple directions. This effectively increases the contact area between the workpiece and the heat treatment medium, helps to improve the uniformity of the workpiece heating, reduces insufficient medium contact, and assists in improving the heat treatment effect. In addition, the hollow structure design can reduce the overall weight of the equipment, reduce the load of hoisting and transportation operations, and make the operation of immersing the entire frame 1 into the heat treatment tank easier, thus balancing the heat treatment effect and the ease of operation of the equipment.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
