[0030] Please see Figures 1 to 9 The present application describes, through the following embodiments, a wind support device for carrying a silicon carbide blank tube, comprising a flow guide assembly 100 and a housing 200, wherein:
[0031] The outer shell 200 is sleeved on the guide component 100, and there is a first gap between the outer shell 200 and the outer wall of the guide component 100. The outer shell 200 is provided with at least one group of air inlets 210, and each group of the air inlets 210 includes a plurality of the air inlets 210; the guide component 100 includes a plurality of conical rings 110 and support columns 120, the plurality of conical rings 110 are sleeved in sequence, and the support columns 120 pass through the sleeved plurality of conical rings 110 in sequence and are connected to the side walls of the conical rings 110, the conical angle of the conical rings 110 is 30° to 70°, and there is a second gap 130 between adjacent conical rings 110.
[0032] In this embodiment, the length of the guide component 100 can be specifically designed according to the actual production batch or formulation requirements, and the number of the conical rings 110, as well as the inner diameter and outer diameter of the conical ring 110 can also be set according to actual needs; the shape of the shell 200 is preferably the same as the shape of the guide component 100, and the inner diameter of the shell 200 is slightly larger than the outer diameter of the guide component 100, thereby, there is a first gap between the shell 200 and the outer wall of the guide component 100; when a plurality of the conical rings 110 are sleeved to form the guide component 100, a port of the first conical ring 110 is the feed port (feed end) of the guide component 100, and a port of the last conical ring 110 that is away from the first conical ring is the discharge port (discharge end) of the guide component 100; the support column 120 passes through the sleeved plurality of the conical rings 110 in sequence, Connected to the side wall of the conical ring 110, one end of the support column 120 is connected to the feed port, and the other end of the support column 120 is connected to the discharge port, and the support column 120 is used to connect several conical rings 110; there is a second interval 130 between adjacent conical rings 110, and a guide channel is formed between two adjacent conical rings 110, and the guide channel is used to pass the airflow; the cone angle of the conical ring 110 is 30° to 70° (specifically, it can be set according to the actual formulation of technicians in this field), which is used to change the flow direction of the airflow inside the guide component 100; the second interval 130 is the distance between the outer wall of the two adjacent first conical rings 110 and the inner wall of the second conical ring 110, and the second interval 130 is adjustable, and the airflow pressure inside the guide component 100 can be changed by adjusting the second interval 130.
[0033] When in use, first, high-pressure gas is introduced into the gas inlet 210, and the extruded silicon carbide blank tube enters the flow guide component 100 from the feed port of the flow guide component 100; under the action of the conical ring 110, an airflow is formed inside the flow guide component 100. Under the action of the airflow, the silicon carbide blank tube can be lifted and moved forward until entering the next process section.
[0034] The above-mentioned device provided in the present application is used to carry the silicon carbide blank tube after extrusion. The extruded silicon carbide blank tube is lifted by the airflow and maintained in a stable position, which can effectively prevent the blank tube from contacting the device, avoid deformation or damage caused by external forces, and enable the silicon carbide blank tube to move forward, thereby improving the quality of the produced silicon carbide blank tube.
[0035] Specifically, the first interval is 3 mm to 5 mm.
[0036] It should be noted that the transportation of silicon carbide blank tubes is not suitable for too fast speeds, that is, the flow rate of the airflow generated inside the flow guide component 100 cannot be too large. When the flow rate is too large, the airflow may damage the silicon carbide blank tube in the process of moving the silicon carbide blank tube forward; when the flow rate is too small, the airflow blown out from the flow guide component 100 is not strong enough to lift the silicon carbide blank tube. Therefore, when the first interval is 3 mm to 5 mm, the airflow velocity in the flow guide component 100 is optimal, which can not only lift the silicon carbide blank tube, but also make the silicon carbide blank tube move forward at a suitable speed under the action of the airflow, without causing damage to the silicon carbide blank tube.
[0037] The second interval 130 is 2 mm to 5 mm.
[0038] Specifically, the second interval 130 is the distance between the outer wall of the two adjacent first conical rings 110 and the inner wall of the second conical ring 110. When the second interval 130 is too small, the airflow pressure inside the guide component 100 is relatively large. If the airflow pressure is too large, it will also cause slight damage to the surface of the silicon carbide blank tube; when the second interval 130 is too large, the airflow pressure inside the guide component 100 is relatively small, the silicon carbide blank tube cannot be lifted up by the airflow, and the forward movement speed of the silicon carbide blank tube is too slow, affecting its efficiency; therefore, when the second interval 130 is 2 mm to 5 mm, the airflow pressure inside the guide component 100 is optimal, the airflow will not cause slight damage to the surface of the silicon carbide blank tube, and can also lift the silicon carbide blank tube, so that the silicon carbide blank tube moves forward, which can improve production efficiency.
[0039] Preferably, the number of the support columns 120 is 2 to 4.
[0040] Considering that when a group of air inlets 210 are provided, the airflow distributed in the guide assembly 100 located at the air inlets 210 is too concentrated, and the silicon carbide blank tube located at the air inlets 210 is impacted by the airflow to a greater extent, which may cause slight local damage to the silicon carbide blank tube. In some preferred embodiments, the outer shell 200 is provided with a plurality of groups of air inlets 210, and in the length direction of the outer shell 200, the plurality of groups of air inlets 210 are arranged in an array at intervals in the outer shell 200.
[0041] In this embodiment, the number of the multiple groups of air inlets 210 provided on the housing 200 can be set according to the length of the housing 200. Preferably, the air inlets 210 are provided in two or three groups.
[0042] When in use, high-pressure gas is introduced from the air inlet 210 of each group and evenly distributed in the housing 200. Under the action of the conical ring 110 and the guide plate 111, an airflow is formed. The airflow in the guide assembly 100 lifts the silicon carbide blank tube and makes the silicon carbide blank tube move forward.
[0043] The advantage of configuring the air inlets 210 in multiple groups is that it can prevent the local airflow in the guide assembly 100 from being too concentrated, prevent the silicon carbide blank tube located at the air inlet 210 from being greatly impacted by the airflow, and effectively prevent the silicon carbide blank tube from being slightly damaged locally.
[0044] In order to make the airflow formed after the high-pressure gas passes into the air inlet 210 to be more evenly distributed in the guide component 100, in some preferred embodiments, in each group of the air inlets 210, multiple air inlets 210 are arrayed along the circumference of the outer shell 200, and at least one group of the air inlets 210 is located at the feed end of the outer shell 200.
[0045] In this embodiment, the number of each group of air inlets 210 is preferably three, and the three air inlets 210 are arranged along the circumference of the housing 200 , and at least one group of air inlets 210 is located at the feed end of the housing 200 .
[0046] When in use, when the outer shell 200 is placed on the guide component 100, high-pressure gas is first introduced into a group of air inlets 210 located at the feed end of the outer shell 200. Since there are three air inlets 210 and they are arranged in an array along the circumference of the outer shell 200, high-pressure gas is introduced from the three air inlets 210 respectively and distributed in the outer shell 200. Under the action of the conical ring 110 and the guide plate 111, the high-pressure gas forms an airflow to lift the silicon carbide blank tube, and the airflow is more evenly distributed inside the guide component 100, so that the silicon carbide blank tube will not shake left and right in the guide component 100 when moving forward, so as to cause damage to it.
[0047] The air inlet 210 is a cylindrical hollow opening structure, and the inner diameter of the air inlet 210 is 3 mm to 10 mm. In this embodiment, the number of the air inlets 210 is 3, which are respectively arranged at the feed end of the housing 200 and are evenly distributed along the circumference of the outer wall of the housing 200; wherein, the inner diameter of the air inlet 210 is 3 mm to 10 mm, and the advantage of such a setting is that when in use, high-pressure gas can quickly pass into the guide assembly 100 through the air inlet 210. It should be noted that the number and inner diameter of the air inlet 210 can be set according to actual needs.
[0048] Considering the wind support device for carrying silicon carbide blank tubes provided in the present application, when the product is in use, it is stationary in the guide assembly 100, and the product is affected by gravity, resulting in changes in the straightness and roundness of the product, affecting the quality of the product. Further, the following embodiments are provided to solve this problem.
[0049] Furthermore, the conical ring 110 is provided with a plurality of guide plates 111, which are arranged in an inclined array along the circumference of the outer conical surface of the conical ring 110, the angle between the guide plate 111 and the cross section of the outer conical surface is a first angle 112, the angle between the guide plate 111 and the end surface of the outer conical surface is a second angle 113, and any two adjacent conical rings 110 are connected via the guide plates 111 (it should be noted that, in the present embodiment, the support column 120 may or may not be provided).
[0050] The first end of the guide plate 111 is connected to the outer side of one end of the conical ring 110, and the second end of the guide plate 111 is connected to the outer side of the other end of the conical ring 110. A guide channel is formed between two adjacent guide plates 111 distributed circumferentially along the outer cone surface of the conical ring 110, and the guide channel is used to pass the rotating airflow; the first angle 112 and the second angle 113 can be set according to actual formulation by technicians in this field, and are used to change the flow direction of the airflow inside the guide assembly 100.
[0051] When in use, the high-pressure gas introduced into the air inlet 210 is distributed in the housing 200, and the extruded silicon carbide blank tube enters the flow guide assembly 100 from the feed port of the flow guide assembly 100; under the action of the flow guide plate 111 and the conical ring 110, a rotating airflow is formed inside the flow guide assembly 100. Under the action of the rotating airflow, the silicon carbide blank tube can be lifted up and rotated and moved forward until entering the next process section.
[0052] In the above-mentioned device provided by the present application, the extruded silicon carbide blank tube is lifted up by the airflow and maintained in a stable position, which can effectively prevent the blank tube from contacting the device and avoid deformation or damage caused by external forces. Moreover, since the silicon carbide blank tube rotates and moves forward, its straightness and roundness will not change, thereby improving the quality of the produced silicon carbide blank tube.
[0053] Specifically, the first angle 112 is 60° to 90°.
[0054] The angle between the guide plate 111 and the cross-section of the outer cone is a first angle 112, and when the first angle 112 is 60° to 90°, the high-pressure gas introduced into the outer shell 200 forms an airflow under the action of the conical ring 110 and the guide plate 111, and the airflow can gather toward the middle of the guide component 100, and the effect of the airflow gathering toward the middle of the guide component 100 is best. The extruded silicon carbide blank tube entering from the feed port can be lifted by the airflow, so that the silicon carbide blank tube does not contact the inner wall of the guide component 100, thereby preventing it from being deformed or damaged by external force.
[0055] Preferably, the second angle 113 is 30° to 60°.
[0056] The angle between the guide plate 111 and the end face of the outer cone is a second angle 113. If the second angle 113 is greater than 60°, the rotating airflow cannot rotate the silicon carbide blank tube. If the second angle 113 is less than 30°, the rotating airflow will also hinder the silicon carbide blank tube from moving forward. When the second angle 113 is between 30° and 60°, the airflow entering the outer shell 200 can rotate, and under the action of the rotating airflow, the silicon carbide blank tube can rotate and move forward.
[0057] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
