Description

Technical Field

[0001] This utility model relates to the field of inoculant preparation technology, and more specifically, to a water-cooled crystallization apparatus for preparing inoculants that promote grain refinement of high-temperature alloys. Background Technology

[0002] The production process of inoculants that promote grain refinement in high-temperature alloys mainly includes steps such as raw material preparation and batching, smelting and alloying, preparation of grain refiners, compounding and molding, and post-processing and inspection. Among them, the grain refinement process of inoculants requires the use of water-cooled crystallization equipment. Water-cooled crystallization equipment can quickly reduce the temperature of the alloy melt by water cooling, so that it can quickly reach a supersaturated state, thereby promoting the formation of crystal nuclei and the precipitation of crystals. This rapid cooling method helps to obtain a fine and uniform grain structure and improve the grain refinement effect of the inoculant. However, existing technologies have some problems: existing water-cooled crystallization equipment for preparing inoculants that promote grain refinement of high-temperature alloys usually puts the raw materials directly into the crystallization tank for crystallization. However, existing water-cooled crystallization equipment does not stir the raw materials sufficiently, resulting in a low crystallization rate. Therefore, we propose a water-cooled crystallization equipment for preparing inoculants that promote grain refinement of high-temperature alloys. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for preparing inoculants that promote grain refinement in high-temperature alloys using a water-cooled crystallization apparatus.

[0004] According to a first aspect of this utility model, a water-cooled crystallization apparatus for preparing an inoculant that promotes grain refinement of high-temperature alloys is provided, comprising a support frame, a cooling tower fixedly connected to the support frame, a partition plate fixedly connected inside the cooling tower, holes formed in the partition plate, a crystallization tank fixedly connected to the partition plate, a rotating shaft rotatably connected inside the crystallization tank, a stirring assembly mounted on the rotating shaft, a driving assembly mounted on the cooling tower for driving the rotating shaft to rotate, a material conveying assembly mounted on the cooling tower, a water inlet pipe fixedly connected to one side of the cooling tower, and a water outlet pipe fixedly connected to the other side of the cooling tower.

[0005] Optionally, the stirring assembly includes a stirring shaft, which is rotatably connected inside a rotating shaft, and a first stirring blade is fixedly connected to the outer wall of the stirring shaft.

[0006] Optionally, a connecting rod is fixedly connected to the rotating shaft, a cleaning rod is fixedly connected to the connecting rod, a scraper is fixedly connected to one side of the cleaning rod, and a second stirring blade is fixedly connected to the other side of the cleaning rod, with the second stirring blade and the first stirring blade being arranged alternately.

[0007] Optionally, the drive assembly includes a motor, which is fixedly connected to the cooling tower. A first conical tooth is keyed to the output end of the motor, and a second conical tooth is fixedly connected to the rotating shaft, wherein the second conical tooth meshes with the first conical tooth.

[0008] Optionally, a third conical tooth is fixedly connected to the rotating shaft, and the third conical tooth meshes with the first conical tooth.

[0009] Optionally, the feeding assembly includes a feed pipe, which is fixedly connected to the cooling tower. Two sets of feeding pipes are fixedly connected to the feed pipe and are fixedly connected to the crystallization tank. The feeding pipe is S-shaped.

[0010] Optionally, a discharge pipe is fixedly connected to the crystallization tank, the discharge pipe passes through the cooling tower, and a valve is installed on the discharge pipe.

[0011] According to one embodiment of this disclosure, the solution is stirred by a stirring assembly to accelerate the crystallization rate of the solution. The driving assembly drives the stirring shaft to rotate, which in turn drives the first stirring blade to rotate, so that the solute in the solution is evenly distributed, accelerating the mass transfer process between the solute and the solvent, thereby accelerating the crystallization rate of the inoculant. While the driving assembly drives the stirring shaft, it also drives the rotating shaft to rotate in the opposite direction, thereby causing the connecting rod to rotate, which in turn causes the cleaning rod to rotate. The rotation of the cleaning rod causes the second stirring blade to rotate. The second stirring blade is staggered with the first stirring blade and rotates in opposite directions, thereby increasing the shear force on the solution, making the solution stir faster and accelerating the crystallization rate. At the same time, the rotation of the cleaning rod also causes the scraper to rotate, thereby scraping off the crystals on the inner wall of the crystallization tank and preventing them from adhering to the inside of the crystallization tank.

[0012] This invention is equipped with a feeding assembly. The solution flows into two sets of feeding pipes through the feed pipe. The feeding pipes are S-shaped, which prolongs the time it takes for the solution to pass through the feeding pipes. This allows the solution to be initially cooled by cooling water after passing through the feeding pipes, thereby accelerating the crystallization of the solution in the crystallization tank.

[0017] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0018] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0019] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0020] like Figure 1-4 As shown, a water-cooled crystallization device for preparing an inoculant that promotes grain refinement of high-temperature alloys includes a support 1, which is welded from multiple sets of stainless steel pipes. The main function of the support 1 is to support the entire device and ensure its normal operation.

[0021] Furthermore, a cooling tower 2 is fixedly connected to the support 1. The cooling tower 2 is made of stainless steel and is used to carry cooling water.

[0022] Furthermore, a partition plate 3 is fixedly connected inside the cooling tower 2, and a crystallization tank 4 is fixedly connected on the partition plate 3. The crystallization tank 4 is made of stainless steel and is used for raw material crystallization.

[0023] Furthermore, a rotating shaft 5 is rotatably connected inside the crystallization tank 4, and a stirring assembly 6 is provided on the rotating shaft 5. The stirring assembly 6 includes a stirring shaft 61, which is rotatably connected inside the rotating shaft 5, and a first stirring blade 62 is fixedly connected to the outer wall of the stirring shaft 61.

[0024] Specifically, the driving component 7 drives the stirring shaft 61 to rotate, and the rotation of the stirring shaft 61 will drive the first stirring blade 62 to rotate, so that the solute in the solution is evenly distributed, the mass transfer process between the solute and the solvent is accelerated, thereby accelerating the crystallization rate of the inoculant.

[0025] Furthermore, a connecting rod 63 is fixedly connected to the rotating shaft 5, a cleaning rod 64 is fixedly connected to the connecting rod 63, a scraper 65 is fixedly connected to one side of the cleaning rod 64, and a second stirring blade 66 is fixedly connected to the other side of the cleaning rod 64. The second stirring blade 66 and the first stirring blade 62 are arranged alternately.

[0026] Specifically, while the drive assembly 7 drives the stirring shaft 61, it also drives the rotating shaft 5 to rotate in the opposite direction, thereby causing the connecting rod 63 to rotate, which in turn causes the cleaning rod 64 to rotate. After the cleaning rod 64 rotates, it will drive the second stirring blade 66 to rotate. The second stirring blade 66 and the first stirring blade 62 are staggered and rotate in opposite directions, thereby increasing the shear force on the solution, making the solution stir faster and accelerating the crystallization rate. At the same time, when the cleaning rod 64 rotates, it will also cause the scraper 65 to rotate, thereby scraping off the upper crystals on the inner wall of the crystallization tank 4 and preventing them from adhering to the inside of the crystallization tank 4.

[0027] Furthermore, a drive assembly 7 is provided on the cooling tower 2. The drive assembly 7 is used to drive the rotating shaft 5 to rotate. The drive assembly 7 includes a motor 71, which is fixedly connected to the cooling tower 2. A first conical tooth 72 is keyed to the output end of the motor 71. A second conical tooth 73 is fixedly connected to the rotating shaft 5. The second conical tooth 73 meshes with the first conical tooth 72.

[0028] Furthermore, a third conical tooth 74 is fixedly connected to the rotating shaft 5, and the third conical tooth 74 meshes with the first conical tooth 72.

[0029] Specifically, after the motor 71 starts, it drives the first conical tooth 72 to rotate. The rotation of the first conical tooth 72 will simultaneously drive the second conical tooth 73 and the third conical tooth 74 to rotate. The second conical tooth 73 and the third conical tooth 74 rotate in opposite directions, which makes the stirring shaft 61 and the cleaning rod 64 rotate in opposite directions. This also makes the second stirring blade 66 rotate in opposite directions to the first stirring blade 62, thereby increasing the stirring rate and accelerating crystallization.

[0030] Furthermore, a water inlet pipe 9 is fixedly connected to one side of the cooling tower 2, which is used to add cooling water into the cooling tower 2. A water outlet pipe 10 is fixedly connected to the other side of the cooling tower 2, which is used to discharge the cooling water into the cooling tower 2. The water inlet pipe 9 and the water outlet pipe 10 are connected to an external cooling water circulation device.

[0031] Specifically, the water inlet pipe 9 is located below the partition 3, and the water outlet pipe 10 is located above the partition 3. After the cooling water enters the device through the water inlet pipe 9, it cools the crystallizer 4, causing the solution inside to crystallize. Then, the cooling water flows from the holes in the partition 3 to the conveying pipe 82, and finally flows out of the device through the water outlet pipe 10.

[0032] Furthermore, a material conveying assembly 8 is provided on the cooling tower 2. The material conveying assembly 8 includes a feed pipe 81, which is fixedly connected to the cooling tower 2. Two sets of material conveying pipes 82 are fixedly connected to the feed pipe 81 and are fixedly connected to the crystallization tank 4. The material conveying pipes 82 are in an "S" shape.

[0033] Specifically, the solution flows into two sets of conveying pipes 82 through the feed pipe 81. The conveying pipes 82 are "S" shaped, which prolongs the time for the solution to pass through the conveying pipes 82. As a result, the solution will be initially cooled by cooling water after passing through the conveying pipes 82, thereby accelerating the crystallization rate of the solution in the crystallization tank 4.

[0034] Furthermore, a discharge pipe 11 is fixedly connected to the crystallization tank 4. The discharge pipe 11 passes through the cooling tower 2 and is equipped with a valve 12. The discharge pipe 11 is used to discharge the crystals from the device, and the valve 12 is used to control whether the discharge pipe 11 is open.

[0035] The above-mentioned inoculant for preparing high-temperature alloy grain refinement uses a water-cooled crystallization device. The solution is stirred by a stirring assembly 6 to accelerate the crystallization rate. A driving assembly 7 drives a stirring shaft 61 to rotate, which in turn drives the first stirring blade 62 to rotate, resulting in a uniform distribution of the solute in the solution and accelerating the mass transfer process between the solute and solvent, thus accelerating the crystallization rate of the inoculant. Simultaneously, the driving assembly 7 drives the stirring shaft 61 and the rotating shaft 5 to rotate in the opposite direction, causing the connecting rod 63 to rotate, which in turn causes the cleaning rod 64 to rotate. The rotation of the cleaning rod 64 then drives the second stirring blade 66 to rotate. The second stirring blade 66 and the first stirring blade 62 are staggered and rotate in opposite directions, increasing the shear force on the solution, making the solution stir faster and accelerating the crystallization rate. Simultaneously, the rotation of the cleaning rod 64 also causes the scraper 65 to rotate, scraping off the upper crystals from the inner wall of the crystallization tank 4, preventing them from adhering to the inside of the crystallization tank 4.

[0036] This utility model is equipped with a feeding assembly 8. The solution flows into two sets of feeding pipes 82 through the feed pipe 81. The feeding pipes 82 are "S" shaped, which prolongs the time for the solution to pass through the feeding pipes 82. As a result, the solution will be initially cooled by cooling water after passing through the feeding pipes 82, thereby accelerating the crystallization of the solution in the crystallization tank 4.
