Description

Technical Field

[0001] This application relates to the field of silicon carbide particle processing technology, and in particular to a quick-change screen grading device for silicon carbide particles. Background Technology

[0002] In the production of silicon carbide, particles with uneven particle size are inevitably generated during the reaction, crushing and refining processes. Furthermore, different application scenarios have vastly different requirements for the particle size and purity of silicon carbide. Therefore, it is necessary to separate and screen the particles according to their size or density through a grading process to ensure the uniformity of the product particle size, remove impurities and unqualified particles, and match the customized needs of downstream applications. This step is crucial for ensuring the quality of silicon carbide products and expanding their application range. It serves as both a quality verification of the preceding processes and an important guarantee for providing "customized products" for subsequent applications.

[0003] Current silicon carbide grading devices have significant shortcomings in terms of the ease of filter replacement. Most devices still use traditional methods such as bolt fastening and flange connection, which require the use of tools such as wrenches to disassemble the fasteners one by one during replacement. This process is cumbersome and time-consuming, and takes even longer if multiple grading screens are involved. This seriously affects the efficiency of filter replacement and further affects the grading efficiency of silicon carbide particles. To address these issues, we propose a quick-change screen grading device for silicon carbide particles. Utility Model Content

Detailed Implementation

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] Example 1: Please see Figure 1 This utility model discloses a quick-change screen grading device for silicon carbide particles, comprising a base 1, a screen frame 2 disposed above the base 1, and a set of screen bodies 3 mounted on the screen frame 2. A vibration structure is provided between the base 1 and the screen frame 2. The vibration structure includes a vibration motor 4 mounted on the upper surface of the base 1. The output end of the vibration motor 4 is connected to the bottom surface of the screen frame 2. A set of stabilizing springs 5 ​​is provided on both sides of the vibration motor 4. The top and bottom ends of each stabilizing spring 5 are respectively connected to the upper surface of the base 1 and the bottom surface of the screen frame 2. The two sets of stabilizing springs... Stabilizing frames 6 are provided on the opposite sides of the springs 5, and the stabilizing frames 6 are slidably connected to the bottom of the screen frame 2. The operation of the vibration motor 4 can drive the screen frame 2 to vibrate, and the screen body 3 will screen the silicon carbide particles. When the screen frame 2 vibrates, the stabilizing springs 5 ​​and stabilizing frames 6 will reinforce and stabilize the bottom of the screen frame 2, further improving its stability during vibration. A set of discharge cylinders 9 are embedded on the right side of the screen frame 2. Silicon carbide particles of different sizes at the screening point will be discharged from the discharge cylinders 9 for easy collection by the staff.

[0017] Example 2: Please see Figure 1 , Figure 2 and Figure 3The screen frame 2 is provided with a quick-installation assembly 7 on its front side. The quick-installation assembly 7 includes multiple sets of fixing blocks 701 fixedly connected to the front side of the screen frame 2. Each set of fixing blocks 701 has a groove 702 on one side close to each other. A compression spring 703 is fixedly connected to the inner wall of each groove 702. A trapezoidal stop block 704 is fixedly connected to one end close to each other of each set of compression springs 703. When installing the screen body 3, the screen body 3 is pushed into the screen frame 2. When the screen body 3 moves, it will squeeze the inclined surface of the trapezoidal stop block 704. After being subjected to force, the trapezoidal stop block 704 will compress the compression spring 703 and retract into the groove 702. As the screen body 3 is gradually pushed, the screen body 3 will pass through the trapezoidal stop block 704. At this time, the compression spring 703 will extend and push the trapezoidal stop block 704. The trapezoidal stop block 704 will move to the front of the screen body 3 and limit it, thereby stabilizing it on the screen frame 2 and enabling quick installation.

[0018] Each compression spring 703 has a slide rod 705 inside. One end of each slide rod 705 is connected to one side of the trapezoidal stop 704, and the other end of each slide rod 705 passes through the fixing block 701 and is fixedly connected to the limiting plate 706. The slide rod 705 and the fixing block 701 are slidably connected. By using the cooperation of the slide rod 705 and the limiting plate 706, the trapezoidal stop 704 can be stabilized, so that the trapezoidal stop 704 can move smoothly in the horizontal position, ensuring the stability of the trapezoidal stop 704 in holding the screen body 3, and also preventing the compression spring 703 from bending.

[0019] Example 3: Please see Figure 1 , Figure 2 and Figure 4 Each screen body 3 has a quick-release assembly 8 on its front side for pushing the quick-release assembly 7 away from the screen body 3. The quick-release assembly 8 includes a turntable 801 rotatably connected to the front side of each screen body 3. Each turntable 801 has a set of push plates 802 rotatably connected to its front side, and each push plate 802 has a top plate 803 rotatably connected to its back side. When disassembling the screen body 3, simply rotate the turntable 805. The turntable 801 will then drive the push plates 802 to deflect. The other end of the push plates 802 will push the top plate 803. The top plate 803 will then push the trapezoidal stop 704 to one side of the screen body 3's movement trajectory. Then, pulling the screen body 3 will remove it from inside the screen frame 2, further simplifying the replacement efficiency of the screen body 3 and ensuring the grading efficiency of silicon carbide particles.

[0020] Each top plate 803 has a guide frame 804 slidably connected to its outer surface. The back of each guide frame 804 is connected to the front of the screen body 3. The guide frame 804 can guide the movement of the top plate 803, thereby ensuring that it accurately pushes the trapezoidal stop 704 to move. Each turntable 801 has a rotating plate 805 fixedly connected to its front. The outer surface of each rotating plate 805 is covered with an anti-slip sleeve. The rotating plate 805 facilitates the rotation of the turntable 801 by the operator, further simplifying the disassembly of the screen body 3.

[0021] The working principle of this application is: When the screen body 3 is installed, it is pushed into the screen frame 2. As the screen body 3 moves, it squeezes the inclined surface of the trapezoidal stop 704. After being subjected to force, the trapezoidal stop 704 compresses the compression spring 703, which then retracts into the groove 702. As the screen body 3 is gradually pushed, it passes through the trapezoidal stop 704. At this time, the compression spring 703 extends and pushes the trapezoidal stop 704, which then moves to the front of the screen body 3 to limit its movement, thus stabilizing it on the screen frame 2. For disassembly, simply rotate the rotating plate 805. The turntable 801 will then drive the push plate 802 to deflect. The other end of the push plate 802 will push the top plate 803, which will push the trapezoidal stop 704 to one side of the screen body 3's movement trajectory. Then, pulling the screen body 3 will remove it from the screen frame 2, further simplifying the replacement efficiency of the screen body 3 and ensuring the grading efficiency of silicon carbide particles.
