Description

Technical Field

[0001] This utility model relates to the field of metal crystallization technology, specifically to a multi-stage gradient cooling crystallizer. Background Technology

[0002] A multi-stage gradient cooler is a device that divides the cooling process into multiple stages, each with a different cooling intensity or temperature gradient. This can prevent large thermal stress or cracks from forming inside the material and can control the grain structure and orientation.

[0003] In traditional equipment, the material flows in the central region during use, resulting in poor cooling efficiency, coarse grains, and difficulty in heat dissipation, leading to slow cooling in the central part and disordered crystal orientation.

[0004] Secondly, if relying on natural flow, the material is prone to accumulate or concentrate at the bottom, resulting in uneven cooling, which may lead to localized overcooling or incomplete solidification.

[0005] Finally, if the temperature distribution throughout the cooling process is uniform and cannot meet the crystallization requirements of complex materials, it may result in cooling too fast (causing cracks) or too slow (causing grain coarsening). Summary of the Invention

[0006] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a multi-stage gradient cooling crystallizer to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a multi-stage gradient cooling crystallizer, comprising a main body, an operating mechanism, and a cooling mechanism. The operating mechanism includes a support frame and a feed pipe. The support frame is fixedly installed at the bottom of the main body, and the feed pipe is fixedly installed on the main body. An air jet pipe is installed on the feed pipe. The cooling mechanism includes a first cooling component and a second cooling component. The first cooling component and the second cooling component are fixedly installed inside the main body, and a third cooling component is fixedly installed on the main body.

[0008] Preferably, the first, second, and third cooling components are provided with inner walls and connecting rods, and the connecting rods are distributed in a circumferential array on the inner walls to facilitate the operation of the cooling mechanism.

[0009] In a further preferred embodiment, the first, second, and third cooling components are provided with inlet pipes and outlet pipes to facilitate the circulation of coolant.

[0010] In a further preferred embodiment, the feed pipe is provided with a diffuser, the main body is provided with an installation gap, and the first cooling element, the second cooling element and the third cooling element are fixedly installed inside the installation gap to facilitate the cooling and crystallization of the material.

[0011] In a further preferred embodiment, the first, second, and third cooling components are provided with cooling pipes to facilitate the delivery of coolant.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a multi-stage gradient cooling crystallizer, which has the following beneficial effects: In this invention, by setting up an operating mechanism, with the cooperation of components such as the support frame and the feed pipe, the material in this device directly adheres to the inner wall of the crystallizer after entering the device, which increases the contact area between the material and the cooling surface and greatly improves the heat transfer efficiency.

[0013] By incorporating components such as a jet pipe and a feed pipe, the jet pipe of this device can effectively propel the material toward the cooling surface, preventing the material from stagnating or accumulating.

[0014] In this invention, by setting up a cooling mechanism, the cooling section of the device is set with multiple different temperature zones under the mutual cooperation of components such as the first cooling component and the second cooling component, so as to avoid overcooling or thermal shock and make grain growth more controlled.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figs. 1-3 A multi-stage gradient cooling crystallizer includes a main body 1, an operating mechanism, and a cooling mechanism. The operating mechanism includes a support frame 2 and a feed pipe 3. The support frame 2 is fixedly installed at the bottom of the main body 1, and the feed pipe 3 is fixedly installed on the main body 1. An air jet pipe 4 is installed on the feed pipe 3. The cooling mechanism includes a first cooling component 5 and a second cooling component 6. The first cooling component 5 and the second cooling component 6 are fixedly installed inside the main body 1, and a third cooling component 7 is fixedly installed on the main body 1.

[0019] In this embodiment, the operating mechanism includes a support frame 2 and a feed pipe 3. During use, the material directly enters the feed pipe 3. Under the action of the diffuser 12, the material can be evenly distributed on the inner wall 8. Furthermore, the support frame 2 facilitates the gravity flow of the material, and the jet pipe 4 allows the material to slide more smoothly inside the body 1 in conjunction with gravity flow.

[0020] In this embodiment, the cooling mechanism includes a first cooling element 5 and a second cooling element 6. In use, the external coolant directly enters the input pipes 10 of the first cooling element 5, the second cooling element 6, and the third cooling element 7 installed inside the mounting gap 13 of the main body 1. Under the action of the first cooling element 5, the second cooling element 6, and the third cooling element 7, the connecting rod 9 can transmit the temperature to the inner wall 8. After the material flows to the inner wall 8, the cooling temperature of each cooling element 14 is different due to the different number of cooling pipes 14, thereby creating multi-stage gradient crystallization.

[0021] Example 2: In summary, during use, the material directly enters the feed pipe 3. Under the action of the diffuser 12, the material can be evenly distributed on the inner wall 8. The main body 1, under the action of the support frame 2, makes the gravity flow of the material more convenient. Under the action of the jet pipe 4, the material can slide more smoothly inside the main body 1 in conjunction with gravity flow. When the material falls into the inner wall 8, the external coolant directly enters the input pipes 10 of the first cooling element 5, the second cooling element 6, and the third cooling element 7 installed in the installation gap 13 of the main body 1. Under the action of the first cooling element 5, the second cooling element 6, and the third cooling element 7, the connecting rod 9 can transmit the temperature to the inner wall 8. After the material flows to the inner wall 8, the cooling temperature of each cooling element 14 is different due to the different number of cooling pipes 14, thus creating multi-stage gradient crystallization.

[0022] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
