[0021] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0022] Reference Figure 1 and Figure 2The utility model is a silica crushing device which is easy to replace and maintain. The main structure includes a crushing box 1. The top of the crushing box 1 is connected to a feed hopper which is wide at the top and narrow at the bottom. Silica enters the crushing box 1 from the feed hopper. The crushing box 1 is provided with a crushing roller 2. The crushing roller 2 is symmetrically rotated by bearings and driven to rotate by a motor. The two crushing rollers 2 are provided with meshing crushing teeth, so that the silica falling between the two can be crushed by the rotating crushing teeth. The lower part of the crushing roller 2 is provided with an inclined filter screen 3. The edge of the filter screen 3 is wrapped with wood or metal to ensure the overall structure of the filter screen 3. The silicon powder after the silica stone is crushed falls on the inclined filter screen 3. The silicon powder of the size meets the size and is discharged from the bottom of the crushing box 1. The large-sized silicon powder is blocked by the filter screen 3, so as to realize the accurate screening control of the silicon powder particles. The side wall of the crushing box 1 is provided with a discharge port 4 at the bottom end of the filter screen 3 in the inclined direction. The discharge port 4 runs through the side wall of the crushing box 1. The large-particle silicon powder rolls along the inclined filter screen 3 and is discharged from the discharge port 4 for further crushing treatment. The side wall of the crushing box 1 opposite to the discharge port 4 is provided with a mounting groove 5. The top end of the filter screen 3 in the inclined direction is arranged at The bottom end of the installation groove 5 is arranged at the discharge port 4 to realize accurate installation and fixation of the filter screen 3. The installation groove 5 and the discharge port 4 are both provided with elastic vibration blocks 6. Specifically, guide holes are arranged at the bottom of the installation groove 5 and the discharge port 4. A guide column is welded or bolted at the bottom of the elastic vibration block 6. The guide column is slidably connected in the guide hole. A vibration spring is arranged between the bottom of the elastic vibration block 6 and the installation groove 5 or the discharge port 4 to realize the up and down vibration of the elastic vibration block 6. The filter screen 3 only needs to cooperate with the two elastic vibration blocks 6 when disassembling and assembling, so that the installed filter screen 3 can be continuously moved up and down during filtering. The filter screen 3 vibrates downward to improve the filtering effect of silicon powder. The top of the filter screen 3 in the inclined direction is movably connected with the elastic vibration block 6 in the installation groove 5. The discharge port 4 is provided with a positioning rod 7 used to cooperate with the bottom end of the filter screen 3 in the inclined direction. Such a structure makes it only necessary to push the filter screen 3 obliquely from the discharge port 4 when installing it, so that the top of the filter screen is connected with the elastic vibration block 6 at the installation groove 5, and then fix the filter screen 3 at the discharge port 4 using the positioning rod 7, so that the disassembly and assembly steps of the filter screen 3 are simpler and faster, which improves the convenience of later replacement and maintenance and ensures the smooth operation of the crushing device.

[0023] Preferably, refer to Figure 3 and Figure 5The elastic vibration block 6 at the discharge port 4 is provided with a slot 8 used to cooperate with the bottom end of the filter screen 3 in the tilting direction. Such a structure enables the bottom end of the filter screen 3 in the tilting direction to be located in the slot 8 after installation, thereby further restricting the position of the filter screen 3 to prevent the filter screen 3 from shaking at angles other than the up and down vibration directions, further ensuring the firmness of the filter screen 3 structure after installation. The positioning rod 7 passes through the slot 8 and is used in conjunction with the filter screen 3. The positioning rod 7 is used to firmly fix the filter screen 3 in the slot 8, ensuring the effect of the filter screen 3 and the slot 8 being snap-fitted.

[0024] Preferably, the positioning rod 7 passes through the side wall of the slot 8 and is threadedly connected thereto, and the end of the positioning rod 7 is movably plugged into the bottom end of the filter screen 3 in the tilting direction. When such a structure is used to fix the filter screen 3 using the positioning rod 7, it is only necessary to rotate the positioning rod 7 to move the end of the positioning rod 7 forward under the action of the threaded connection until it is plugged into and matched with the bottom end of the filter screen 3 in the tilting direction, thereby making the positioning operation of the positioning rod 7 on the filter screen 3 more efficient and stable.

[0025] Preferably, refer to Figure 3 and Figure 4 The elastic vibration block 6 in the installation groove 5 is rotatably connected to a rotating shaft 9 through a bearing, and a plurality of fixing columns 10 that are movably plugged into the top end of the filter screen 3 in the tilting direction are welded or integrally formed on the rotating shaft 9. Such a structure allows the top end of the filter screen 3 in the tilting direction to be plugged into and matched with the fixing columns 10 when the filter screen 3 is installed. At the same time, the fixing columns 10 are located on the rotating rotating shaft 9, so that the filter screen 3 can be rotated after installation so that the bottom end in the tilting direction can be accurately rotated into the slot 8, thereby making the installation of the filter screen 3 smoother, and the bottom end can be more smoothly and firmly matched with the slot 8 after installation.

[0026] Preferably, a plurality of torsion springs 11 are provided between the fixing column 10 and the elastic vibration block 6. Such a structure allows the fixing column 10 and the filter 3 to rotate together under the action of the torsion spring 11 after the positioning rod 7 fixing the filter 3 during disassembly, so that the bottom end of the filter 3 in the tilting direction is automatically separated from the card slot 8, thereby further simplifying the steps of disassembling the filter 3 and improving the convenience of disassembly and replacement.

[0027] Preferably, a baffle 12 is vertically slidably connected to the inner wall of the crushing box 1 for use with the mounting groove 5. The baffle 12 can slide downward to close the mounting groove 5 after the filter screen 3 is installed, thereby preventing silicon powder from entering the mounting groove 5 and falling without passing through the filter screen 3, reducing the occurrence of filtering dead corners, and ensuring the accuracy of the filter screen 3 in filtering silicon powder.

[0028] Working principle: In the structure of the utility model, a discharge port 4 and a mounting groove 5 are arranged on the opposite side walls inside the crushing box 1, and elastic vibration blocks 6 are arranged on both of them. The top and bottom ends of the filter screen 3 in the inclined direction are respectively used in conjunction with the elastic vibration blocks 6 at the mounting groove 5 and the discharge port 4. Such a structure enables the installed filter screen 3 to continuously vibrate up and down under the drive of the two elastic vibration blocks 6, thereby improving the effect of screening and filtering the silicon powder; the top end of the filter screen 3 in the inclined direction is movably plugged into the elastic vibration block 6 in the mounting groove 5, and a positioning rod 7 is arranged at the discharge port 4 to cooperate with the bottom end of the filter screen 3 in the inclined direction. When disassembling the filter screen 3, such a structure only requires the filter screen 3 to be obliquely inserted into the elastic vibration block 6 in the mounting groove 5, and then the positioning rod 7 is used to fix the plugged filter screen 3 at the discharge port 4, thereby making the disassembly and assembly steps of the filter screen 3 simpler and faster, greatly improving the replacement and maintenance efficiency of the filter screen 3, and ensuring the smoothness of the use of the crushing device.
