DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0028] like Figure 1 As shown, the present application provides a crushing and cleaning device 100 for separating a carbon-carbon crucible and a quartz crucible 2. The quartz crucible 2 is located inside the carbon-carbon crucible and is combined with the carbon-carbon crucible. It should be noted that in order to clearly show the crack structure formed on the quartz crucible 2, Figure 1 The carbon-carbon crucible is omitted.

[0029] like Figure 2 、 Figure 3 and Figure 4 As shown, the crushing and cleaning device 100 includes a bracket 11, a vibrating mechanism 12, and an air hammer 13. The bracket 11 is used to mount and support the vibrating mechanism 12 and the air hammer 13. The vibrating mechanism 12 is mounted on the bracket 11 and has a vibration area. The vibration area is used to place the combined carbon-carbon crucible and quartz crucible 2, and is configured to vibrate. After the air hammer 13 strikes the quartz crucible 2, forming a crack in the quartz crucible 2, the quartz crucible 2 located on the vibration area vibrates along with the vibration area, causing the quartz crucible 2 to break and separate from the carbon-carbon crucible. The air hammer 13 has the freedom to move in a predetermined direction and in a vertical direction. The air hammer 13 moves back and forth in the vertical direction to strike the quartz crucible 2. The air hammer 13 moves in the predetermined direction so that when the air hammer 13 strikes the quartz crucible 2, a crack along the predetermined direction is formed in the quartz crucible 2.

[0030] Define a projection plane perpendicular to the vertical direction. The projection of the air hammer 13 along the vertical direction on the projection plane is the air hammer projection. The projection of the vibration area along the vertical direction on the projection plane is the area projection. The air hammer projection is within the area projection. It should be noted that even during the movement of the air hammer 13, the air hammer projection remains within the area projection, allowing the air hammer 13 to act on the quartz crucible 2 within the carbon-carbon crucible.

[0031] Both ends of the crack formed on the quartz crucible 2 penetrate the quartz crucible 2. The air hammer 13 strikes the quartz crucible 2, and the crack formed on the quartz crucible 2 can separate the quartz crucible 2 into at least two halves.

[0032] It should be noted that the quartz crucible 2 can be separated into two halves by only one crack, or by two or more cracks. In the present application, the preset direction is set to: the axial direction of the quartz crucible 2, so that the quartz crucible 2 is separated into two semi-circular columns by the two cracks. In another embodiment, the preset direction can also be set to: the circumferential direction perpendicular to the axial direction of the quartz crucible 2, so that the quartz crucible 2 is separated into two circular columns by a single crack.

[0033] It should be noted that the preset direction can be changed during the movement of the air hammer 13, that is, the crack formed on the quartz crucible 2 can be curved or deflected. In this application, the preset direction is described as the axial direction of the quartz crucible 2.

[0034] After crystal pulling is complete, the combined carbon-carbon crucible and quartz crucible 2 are placed within the vibration zone of the vibration mechanism 12. An air hammer 13 is inserted into the quartz crucible 2 and moves back and forth vertically to strike the crucible 2. During this striking process, the air hammer 13 moves in a predetermined direction, creating several cracks in the crucible 2. The vibration mechanism 12 is then activated, causing the crucible 2 to break along the cracks.

[0035] The present application combines the striking of the air hammer 13 with the vibration of the vibration mechanism 12 to break the quartz crucible 2. Therefore, the present application eliminates the need for manual striking to break the quartz crucible 2 during the separation operation of the quartz crucible 2 and the carbon-carbon crucible, thereby reducing the labor intensity of workers and avoiding the health hazards of workers being exposed to quartz dust for a long time. This further improves the safety of the separation operation of the quartz crucible 2 and the carbon-carbon crucible and reduces the labor costs required.

[0036] Furthermore, the present invention utilizes a method in which the air hammer 13 moves in a preset direction to strike the quartz crucible 2. This method applies uniform force along the cracks in the quartz crucible 2, resulting in a high success rate for breaking the quartz crucible 2. Furthermore, the combination of the striking of the air hammer 13 and the vibration of the vibration mechanism 12 reduces the impact force on the quartz crucible 2, and sparks are not generated during breaking.

[0037] As an implementation method, the vibration mechanism 12 includes a vibration motor 121 and a vibration platform 122. The vibration motor 121 is mounted on the bracket 11, and the vibration platform 122 is mounted on the vibration motor 121. The vibration motor 121 is configured to drive the vibration platform 122 to vibrate, and the vibration platform 122 forms a vibration area. The vibration motor 121 is equipped with a set of adjustable eccentric blocks at each end of its rotor shaft, and the centrifugal force generated by the high-speed rotation of the rotor shaft and the eccentric blocks is used to obtain the excitation force. The excitation force of the eccentric blocks is transmitted to the vibration platform 122, and the vibration platform 122 vibrates under the action of the excitation force, so that the quartz crucible 2 with a crack placed in the vibration area is vibrated and broken.

[0038] As an implementation, the vibration platform 122 includes a base plate 1221 and two fixing protrusions 1222. The two fixing protrusions 1222 are mounted on either side of the base plate 1221 perpendicular to a predetermined direction, with the facing sides of the two fixing protrusions 1222 each having a concave curved surface. The base plate 1221 supports the two fixing protrusions 1222 and the combined carbon-carbon crucible and quartz crucible 2. Once placed on the vibration platform 122, the combined carbon-carbon crucible and quartz crucible 2 are secured by the two fixing protrusions 1222 to prevent relative displacement between the outer carbon-carbon crucible and the base plate 1221 during the crushing of the quartz crucible 2. The concave curved surface of the fixing protrusion 1222 is adapted to the shape of the lower half of the outer peripheral wall of the carbon-carbon crucible, so that: after the concave curved surfaces of the two fixing protrusions 1222 are fitted with the lower half of the outer peripheral wall of the carbon-carbon crucible, on the one hand, the concave curved surfaces of the two fixing protrusions 1222 facing each other have a clamping force on the carbon-carbon crucible; on the other hand, the concave curved surfaces of the two fixing protrusions 1222 facing each other have an upward supporting force on the carbon-carbon crucible.

[0039] like Figure 2 and Figure 3 As shown, as an implementation method, the bottom plate 1221 includes a contact portion 122a and a flip portion 122b. The contact portion 122a contacts the vibration motor 121. The flip portion 122b is rotatably connected to the contact portion 122a, and two fixed protrusions 1222 are located on the flip portion 122b. When the quartz crucible 2 is crushed, the flip portion 122b rotates to a horizontal position, and the vibration motor 121 drives the contact portion 122a and the flip portion 122b to vibrate together. After the quartz crucible 2 is crushed, the flip portion 122b rotates to a tilted position to dump out the quartz crucible 2 debris that has been crushed inside the carbon-carbon crucible.

[0040] Specifically, the crushing and cleaning device 100 also includes a push cylinder 18 and a push block 19. The push cylinder 18 is mounted on the bracket 11. The push block 19 is connected to the flip portion 122b. The push cylinder 18 is configured to push the push block 19 to flip the flip portion 122b relative to the contact portion 122a. The piston rod of the push cylinder 18 extends to push the push block 19 away from the bracket 11, causing the flip portion 122b to flip relative to the contact portion 122a.

[0041] More specifically, the piston rod of the push cylinder 18 is connected to a buffer airbag 20. A contact shaft 21 is provided at one end of the buffer airbag 20 close to the push block 19, and a plurality of limit blocks 22 are provided on one side of the contact shaft 21. The limit blocks 22 are arranged along the axial direction of the contact shaft 21. The limit blocks 22 are triangular in shape, so that a limit surface for limiting the tilt angle of the flip portion 122b is formed at the top of the limit block 22. The piston rod of the push cylinder 18 is extended, and the contact shaft 21 abuts against the bottom of the push block 19; then the piston rod of the push cylinder 18 continues to extend, and the buffer airbag 20 is compressed; then the piston rod of the push cylinder 18 continues to extend, and the push block 19 rotates along the outer peripheral surface of the contact shaft 21 until the bottom of the push block 19 abuts against the limit surface of the limit block 22, at which time the broken quartz crucible 2 slag inside the carbon-carbon crucible is poured out.

[0042] like Figure 5 and Figure 6 As shown, as an implementation method, the crushing and cleaning device 100 includes a buffer mechanism 14, which is installed on the bracket 11. The buffer mechanism 14 is located between the vibration platform 122 and the bracket 11 in the vertical direction. The buffer mechanism 14 is configured to provide a buffer between the vibration platform 122 and the bracket 11. The buffer mechanism 14 provides a buffer for the vibration of the vibration platform 122 to prevent the vibration platform 122 from colliding with the bracket 11, resulting in damage to the carbon-carbon crucible on the vibration platform 122. In the present application, three groups of buffer mechanisms 14 are respectively provided on opposite sides of the vibration platform 122 to achieve a buffering effect between different positions of the vibration platform 122 and the bracket 11.

[0043] Specifically, the buffer mechanism 14 includes a buffer support 141, a movable seat 142 and an elastic member 143. One end of the elastic member 143 is connected to the buffer support 141, and the other end of the elastic member 143 is connected to the movable seat 142. The elastic member 143 has the freedom of extension and contraction in the vertical direction, the movable seat 142 has the freedom of movement in the vertical direction relative to the buffer support 141, the movable seat 142 is in contact with the vibration platform 122, and the buffer support 141 is installed on the bracket 11. In the present application, the elastic member 143 is a spring or the like. The vibration of the vibration platform 122 is first transmitted to the movable seat 142, and the vibration of the movable seat 142 is transmitted to the elastic member 143. The impact force is absorbed by the elastic deformation of the elastic member 143, thereby reducing the impact and vibration brought by the vibration platform 122. Finally, the buffered vibration is transmitted to the bracket 11 through the buffer support 141 to achieve buffering between the vibration platform 122 and the bracket 11.

[0044] More specifically, the movable seat 142 is provided with a sliding groove 1421 extending in the vertical direction, and a shaft 144 is provided through the buffer support 141 and the sliding groove 1421, so that the movable seat 142 is slidably connected to the buffer support 141. The movable seat 142 and the buffer support 141 are slidably connected and form a receiving space for accommodating the elastic member 143. During the vibration process of the vibration platform 122, the movable seat 142 will move back and forth in the vertical direction due to the vibration of the vibration platform 122. Therefore, the sliding groove 1421 that cooperates with the shaft 144 is provided on the movable seat 142, so that during the process of the movable seat 142 moving back and forth in the vertical direction, the freedom of movement of the movable seat 142 relative to the buffer support 141 in the horizontal direction is constrained, while providing the freedom of movement of the movable seat 142 relative to the buffer support 141 in the vertical direction.

[0045] like Figure 7 As shown, as an implementation method, the crushing and cleaning equipment 100 includes an air hammer bracket 15 and a driving mechanism 16. The air hammer bracket 15 is installed on the bracket 11, and the driving mechanism 16 is installed on the air hammer bracket 15. The driving mechanism 16 is configured to be able to drive the air hammer 13 to move along a preset direction. Specifically, a slide rail 17 is provided on the air hammer bracket 15, and the slide rail 17 is arranged along the axial direction of the quartz crucible 2. A movable groove 171 extending along a preset direction is provided on the slide rail 17. The air hammer 13 includes a sliding portion, and the sliding portion is at least partially located in the movable groove 171 and can slide in the movable groove 171. The outer contour of the sliding portion of the air hammer 13 is consistent with the inner contour of the movable groove 171 of the slide rail 17, so that the sliding portion and the movable groove 171 cooperate with each other.

[0046] As an implementation method, the drive mechanism 16 includes a drive motor, a sprocket, and a chain. The drive motor drives the sprocket to rotate, the chain engages with the sprocket, and the sliding portion is fixed to the chain. After the drive motor drives the sprocket to rotate, the sprocket and the chain drive the sliding portion to slide along the movable groove.

[0047] As another implementation, the drive mechanism 16 includes a drive motor, a screw, and a nut. The drive motor drives the screw to rotate. The nut is sleeved on the screw and rotatably connected to the screw. The nut is also connected to or embedded in the sliding portion. After the drive motor drives the screw to rotate, the transmission of the screw and nut drives the sliding portion to slide along the movable groove 171.

[0048] It should be understood that the drive mechanism 16 can be configured to further drive the air hammer 13 to move radially along the quartz crucible 2, so that the air hammer 13 can approach and move away from the inner circumferential wall of the quartz crucible 2. Specifically, the drive mechanism 16 includes a linear module and a rotary motor. The rotary motor is mounted on the air hammer bracket 15. The output shaft of the rotary motor is connected to the linear module to drive the linear module to rotate about the axial direction of the quartz crucible 2. The linear module is connected to the air hammer 13 to drive the air hammer 13 to move along the length direction of the linear module.

[0049] It should be understood that the driving mechanism 16 can be configured to further drive the air hammer 13 to rotate about the axial direction of the quartz crucible 2, so that the air hammer 13 can strike and form cracks at different positions of the quartz crucible 2. Specifically, the driving mechanism 16 includes a rotary motor mounted on the air hammer support 15, and the output shaft of the rotary motor is connected to the air hammer 13 to drive the air hammer 13 to rotate about the axial direction of the quartz crucible 2.
