Description

Technical Field

[0001] This utility model relates to the field of powder single crystal abrasive processing technology, and in particular to a powder single crystal abrasive conveying and cooling system. Background Technology

[0002] Due to its complex manufacturing process and high energy consumption, only a few companies in China have the capability to produce single-crystal powder abrasive materials. These materials have a hardness of 2300-2400 HV, superior toughness compared to brown and white fused alumina, and combine high wear resistance with fracture resistance, making them suitable for high-end applications such as precision grinding and semiconductor wafer polishing.

[0003] In the current production of single-crystal powder abrasives, after high-temperature calcination, the abrasives are transported to the collection box via a conveyor belt. During the transport, the abrasives on the conveyor belt need to be cooled. Usually, multiple fans are arranged on both sides of the conveyor belt for air cooling, but there are problems such as uneven cooling and low cooling efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a powder single crystal abrasive conveying and cooling system.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a powder single-crystal abrasive conveying and cooling system, including a support frame and a conveyor mounted on the support frame. The conveyor includes two baffles mounted opposite each other on the support frame and a conveyor belt disposed between the two baffles. A support plate is provided between the two baffles, extending through the conveyor belt along its width direction. A cooling component is provided at the upper end of the support plate, located inside the conveyor belt and in contact with the top surface of the conveyor belt.

[0006] Cooling components are provided on the front and rear sides of the cooling assembly between the two baffles. The cooling components include cooling rollers installed in the conveyor belt, and the cooling rollers are in contact with the top surface of the conveyor belt.

[0007] Furthermore, the cooling roller includes a hollow roller body and hollow shaft tubes disposed on both sides of the hollow roller body. The two hollow shaft tubes rotatably pass through two baffles respectively. The ends of the hollow shaft tubes that pass through the baffles are provided with rotary joints. The two rotary joints are respectively connected to the first water inlet pipe and the first water outlet pipe.

[0008] Furthermore, the cooling component includes at least two cooling rollers to increase the cooling area and efficiency.

[0009] Furthermore, the cooling assembly includes a cooling platform mounted on the support plate. The cooling platform has a cavity structure and has a water inlet and a water outlet. The water inlet and water outlet of the cooling platform are respectively connected to a second water inlet pipe and a second water outlet pipe.

[0010] Furthermore, the cooling platform has a rectangular structure, with the upper and front sides of the cooling platform transitioning by arcs, and the upper and rear sides of the cooling platform transitioning by arcs, to ensure that the conveyor belt passes smoothly and reduce wear.

[0011] Furthermore, vibration mechanisms are provided on both sides of the cooling assembly on the support plate to prevent abrasive buildup.

[0012] Furthermore, the vibration mechanism is a vibration motor.

[0013] Furthermore, the conveyor also includes a drive roller and a driven roller rotatably disposed between two baffles, one of the baffles being equipped with a drive motor for driving the drive roller to rotate, and the drive roller and the driven roller being connected by a conveyor belt.

[0014] The beneficial effects of this application are as follows: 1. This application achieves uniform and stable cooling of powder single crystal abrasive by setting cooling rollers and cooling tables that are in direct contact with the top surface of the conveyor belt and using contact heat conduction to replace traditional airflow cooling.

[0015] 2. This application abandons the energy-consuming method of continuous airflow from multiple high-power fans and adopts a highly efficient liquid cooling method. Heat energy is effectively carried away through circulating liquid, reducing the overall operating energy consumption of the system.

[0016] 3. The vibration mechanism added in this application can effectively prevent abrasive from accumulating on the surface of the cooling table, ensure uniform abrasive layer thickness, and further enhance the uniformity of cooling effect. Attached Figure Description

It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Please see Figure 1-3 This utility model provides a powder single crystal abrasive conveying and cooling system, including a support 1 and a conveyor mounted on the support 1. The conveyor includes two baffles 2 mounted opposite each other on the support 1 and a conveyor belt 3 disposed between the two baffles 2. A support plate 4 is provided between the two baffles 2, extending through the conveyor belt 3 along its width direction. A cooling component is provided at the upper end of the support plate 4, located inside the conveyor belt 3 and in contact with the inner top surface of the conveyor belt 3. Cooling units are respectively provided on the front and rear sides of the cooling component between the two baffles 2. The cooling unit includes a cooling roller 7 disposed inside the conveyor belt 3, and the cooling roller 7 is in contact with the inner top surface of the conveyor belt 3.

[0023] The conveyor belt 3 is annular, and the support plate 4 is located inside the conveyor belt 3. The two sides of the support plate 4 are respectively connected to two baffles 2 by bolts or welding. The cooling unit includes at least two cooling rollers 7. In this embodiment, the cooling unit includes two cooling rollers 7. The cooling roller 7 includes a hollow roller body and hollow shaft tubes 71 arranged on both sides of the hollow roller body. The two hollow shaft tubes 71 rotatably pass through the two baffles 2 respectively. The ends of the hollow shaft tubes 71 that pass through the baffles 2 are provided with rotary joints. The two rotary joints are respectively connected to the first water inlet pipe and the first water outlet pipe.

[0024] Combination Figure 2 As shown, the cooling assembly includes a cooling platform 5 mounted on the support plate 4. The cooling platform 5 has a hollow structure and includes a water inlet 51 and a water outlet 52. The water inlet 51 and water outlet 52 of the cooling platform 5 are respectively connected to a second water inlet pipe and a second water outlet pipe. The upper surface of the cooling platform 5 is in close contact with the inner top surface of the conveyor belt 3. Both the second water inlet pipe and the first water inlet pipe are connected to a water source. The cooling medium in the cooling platform 5 and the cooling roller 7 is water.

[0025] Specifically, the cooling platform 5 is rectangular, with its upper and front surfaces transitioning to each other via rounded arcs, and its upper and rear surfaces also transitioning to rounded arcs, reducing friction and jamming when the conveyor belt 3 passes through. Vibration mechanisms are respectively installed on both sides of the cooling assembly on the support plate 4. The vibration mechanism is a vibration motor 6. It should be noted that any parts not detailed in this application are prior art.

[0026] In addition, the conveyor also includes a drive roller 31 and a driven roller 32 rotatably disposed between two baffles 2. One of the baffles 2 is equipped with a drive motor 8 for driving the drive roller 31 to rotate. The drive roller 31 and the driven roller 32 are connected by a conveyor belt 3. The conveyor belt 3 is a high-temperature resistant conveyor belt. The drive roller 31 and the driven roller 32 have the same structure and size. The drive roller 31 includes a roller body and connecting shafts located on both sides of the roller body. One of the two connecting shafts of the drive roller 31 is rotatably connected to one of the baffles 2, and the other connecting shaft rotatably passes through the other baffle 2 and its end is connected to the output shaft of the drive motor 8 through a coupling. The two connecting shafts of the driven roller 32 are rotatably connected to the two baffles 2 respectively.

[0027] The high-temperature single-crystal abrasive powder falls onto conveyor belt 3 through the discharge port of the calcining furnace. The drive motor 8 starts, driving conveyor belt 3 and the material on it forward.

[0028] When the material passes through the first cooling element, the cooling water inside the cooling roller 7 begins to circulate, and the heat from the conveyor belt 3 is quickly carried away through contact conduction, thus initially cooling the material.

[0029] Subsequently, the material enters the core cooling zone. The cooling water inside the cooling platform 5 continuously performs high-intensity heat exchange. Due to its large contact area with the conveyor belt 3, it can fully and evenly cool the material. Simultaneously, the vibrating motors 6 on both sides continuously operate, causing the material to bounce slightly on the conveyor belt 3, preventing it from accumulating in front of the cooling platform 5 and ensuring a loose, uniform material layer, thus making cooling more uniform and efficient.

[0030] Finally, the material passes through a second cooling element, where it undergoes final cooling and temperature equalization by cooling roller 7, before being conveyed to a collection box placed at the end of conveyor belt 3. The entire cooling process is completed through contact liquid cooling, which is highly efficient and uniform, significantly superior to traditional air cooling.

[0031] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0032] For example, in other embodiments, unlike the embodiments described above, a control unit is also included. The control unit includes a PLC controller, which is electrically connected to the drive motor 8 and the vibration motor 6, respectively.

[0033] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
