Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silicon carbide processing, and particularly relates to a silicon carbide material ball milling device. BACKGROUND

[0002] Silicon carbide is a compound semiconductor material mainly composed of silicon and carbon. In the mechanical industry, silicon carbide is often used as an abrasive material due to its high hardness, and is used to manufacture grinding tools such as sandpaper and grinding wheels. In the electronic industry, silicon carbide is used to manufacture power electronic devices, radio frequency devices, and optoelectronic devices, as a wide bandgap semiconductor material. Silicon carbide material ball milling devices are widely used in industrial fields that require the pulverization of high-hardness materials such as silicon carbide to micron or even nanometer levels.

[0003] In the process of the current silicon carbide material ball milling device, a certain amount of grinding medium (balls made of high-hardness materials such as zirconium oxide) is loaded into a rotating cylinder. As the cylinder rotates, the grinding medium is lifted to a certain height by the liner plate installed on the cylinder and then falls, impacting and rubbing the silicon carbide material loaded into the cylinder, thereby refining the silicon carbide material. However, due to the high hardness and high strength of the silicon carbide material, the liner plate is rapidly worn out by the silicon carbide material and the grinding medium during the rotation of the cylinder. The existing cylinder is equipped with several liner plates, and each liner plate is fixed by multiple bolts one by one, which is not convenient for maintenance and replacement of the worn-out liner plate. Moreover, the bolts are prone to rotating and falling off after continuous impact, and the stability of the liner plate installation needs to be improved. Secondly, the silicon carbide material and the grinding medium between adjacent liner plates tend to accumulate, and uneven local stress on the liner plate will accelerate the wear of the liner plate. At the same time, the accumulation of the material will affect the efficiency and effectiveness of the grinding. Furthermore, the liner plate is continuously impacted, and the surface heat accumulates, which will cause the hardness and wear resistance of the liner plate to decrease due to thermal softening, making it more susceptible to impact and wear by the grinding balls and silicon carbide particles.

[0004] Therefore, in order to reduce the wear of the cylinder and the liner plate and improve the efficiency and effectiveness of the grinding, the present application provides a silicon carbide material ball milling device. SUMMARY

[0036] With reference to Figures 1-3 The barrel 12 is provided with a plurality of wear-resistant mechanisms 2 in the circumferential direction, and each wear-resistant mechanism 2 comprises a plurality of wear-resistant assemblies 21 arranged on the mounting hole group 16 for protecting the barrel 12 from wear and changing the movement trajectory of the material, and a dismounting assembly 22 arranged on the wear-resistant assembly 21 for dismounting and maintaining the wear-resistant assembly 21.

[0038] With reference to Figures 3-6, the disassembling and assembling component 22 comprises the L-shaped locking rod one 221 and the L-shaped locking rod two 222 which are symmetrically distributed with the mounting column group 212 as the center; the L-shaped locking rod one 221 and the L-shaped locking rod two 222 are oriented left and right, the L-shaped locking rod one 221 and the L-shaped locking rod two 222 are connected through the left-right symmetric bolts 223, the inside of the L-shaped locking rod one 221 is slidably connected with a plurality of clamping strips 224 corresponding to the mounting column group 212, the clamping strips 224 are rotationally connected with the screw rods 226 which are threadedly connected with the L-shaped locking rod one 221 on the side wall inside the L-shaped locking rod one 221; the side wall of the mounting column group 212 close to the clamping strips 224 is provided with the clamping grooves, the two mounting columns are clamped and connected with the corresponding clamping strips 224 through the clamping grooves, the L-shaped locking rod two 222 is fixed with a plurality of abutting piece groups 225 on the side wall close to the corresponding L-shaped locking rod one 221, the abutting piece group 225 comprises two abutting pieces corresponding to the mounting column, the side wall of the mounting column close to the corresponding abutting piece is formed into an arrow shape by two inclined surfaces, the side wall of the abutting piece close to the corresponding mounting column is provided with the V-shaped groove which is matched with the inclined surface of the mounting column.

[0039] When the wear-resistant mechanisms 2 are installed in batches, the arc-shaped lining plates 211 are installed inside the cylinder body 12, the mounting column group 212 is inserted into the corresponding mounting hole group 16 from inside to outside, the adjacent two arc-shaped lining plates 211 are clamped and connected through the connecting mortises 213 and the connecting tenons 214, so as to enhance the connection stability between the plurality of arc-shaped lining plates 211; after a row of arc-shaped lining plates 211 from left to right are installed through the mounting column group 212, the L-shaped locking rod one 221 and the L-shaped locking rod two 222 are respectively limited to the position of the mounting column group 212 from two directions from the outside of the cylinder body 12, the two ends of the L-shaped locking rod one 221 and the L-shaped locking rod two 222 are fixed through the tightening bolts 223, the L-shaped locking rod one 221 is clamped into the corresponding clamping groove of the mounting column group 212 through the clamping strips 224 to quickly lock the position of the mounting column group 212.

[0040] The abutting piece group 225 is attached to the two side walls of the mounting column group 212 which are formed into an arrow shape, the horizontal segment side wall of the L-shaped locking rod one 221 is attached to the remaining one side wall of the mounting column group 212, so as to clamp and support the mounting column group 212 from three directions, which enhances the installation stability between the L-shaped locking rod one 221, the L-shaped locking rod two 222, the mounting column group 212 and the arc-shaped lining plate 211, and reduces the amount of screws used during installation, which helps to save the installation time.

[0041] All the arc-shaped lining plates 211 are fixed in a group of one row from left to right, and the stably installed arc-shaped lining plates 211 protect the cylinder 12 from wear during the grinding process. The convex arc-shaped lining plate 211 side wall increases the contact area between the arc-shaped lining plate 211 and the material, and affects the movement trajectory of the silicon carbide material and the grinding ball, so as to drive the silicon carbide material and the grinding ball to move upwards. After falling down, the silicon carbide material and the grinding ball collide with each other, which is beneficial to speed up the crushing speed.

[0042] When the arc-shaped lining plate 211 needs to be maintained and replaced due to wear, the single arc-shaped lining plate 211 can be quickly disassembled by adjusting the screw rod 226, thereby improving the replacement efficiency. Specifically, the screw rod 226 corresponding to the arc-shaped lining plate 211 to be disassembled is loosened from the outside of the cylinder 12. The screw rod 226 drives the clamping strip 224 to change from the state of being clamped with the mounting column group 212 to the state of being shrunk into the L-shaped locking rod 221. The clamping strip 224 releases the locking of the mounting column group 212. The corresponding arc-shaped lining plate 211 is directly pulled out from the inside of the cylinder 12 to achieve disassembly.

[0043] Referring to Figure 1 and Figure 7 , the anti-piling mechanism 3 includes an anti-piling assembly 31, and the anti-piling assembly 31 includes left and right sliding strips 311 and a sliding piece that drives the left and right sliding strips 311 to slide left and right. The sliding piece includes a sliding groove, and the arc-shaped lining plate 211 is symmetrically provided with the sliding groove centered on the mounting column group 212. The left and right sliding strips 311 are slidably connected to the sliding groove. The left and right sliding strips 311 on adjacent two arc-shaped lining plates 211 are close to each other. The left end of the leftmost left and right sliding strip 311 and the right end of the rightmost left and right sliding strip 311 are both fixed with a fixed seat 312 that slides through the side wall of the cylinder 12. The side of the fixed seat 312 away from the corresponding left and right sliding strip 311 is fixedly connected with a wedge block one 313. The side of the wedge block one 313 away from the fixed seat 312 is inclined. The left side and the right side of the cylinder 12 are both provided with a support frame 32 fixed to the support seat 11. The side wall upper part of the support frame 32 close to the cylinder 12 is fixedly connected with a plurality of wedge block twos 33 in the circumferential direction. The side of the wedge block two 33 away from the support frame 32 is inclined and matched with the wedge block one 313. The wedge block twos 33 on the two support frames 32 are staggered.

[0044] During the grinding process, the left and right sliding strips 311 rotate with the cylinder 12 and the arc-shaped lining plate 211. When the left and right sliding strips 311 drive the fixed seat 312 and the wedge block one 313 to rotate away from the support seat 11, the wedge block one 313 gradually approaches the wedge block two 33. The inclined surface of the wedge block one 313 is attached to the inclined surface of the wedge block two 33. With the rotation of the cylinder 12, the wedge block one 313 is pushed by the wedge block two 33 to drive the left and right sliding strips 311 to slide horizontally on the arc-shaped lining plate 211.

[0045] When the wedge one 313 on the left side of the left and right sliding bar 311 is pushed, it will drive the left and right sliding bar 311 to slide to the right, and the adjacent left and right sliding bar 311 is forced to slide to the right synchronously. The wedge two 33 on the right side of the support frame 32 is staggered with the wedge two 33 on the left side of the support frame 32. When the wedge one 313 on the right side of the left and right sliding bar 311 is pushed, it will drive the left and right sliding bar 311 to slide to the left, and the adjacent left and right sliding bar 311 is forced to slide to the left synchronously. In order to prevent the accumulation of silicon carbide material and grinding balls between the two adjacent rows of arc-shaped lining plates 211 when the arc-shaped lining plate 211 rotates away from the support seat 11, the left and right reciprocating sliding movement of the wedge one 313 prevents the accumulation of silicon carbide material and grinding balls between the two adjacent rows of arc-shaped lining plates 211, reduces the uneven stress on the lining plate, and reduces the wear caused by uneven stress on the lining plate. At the same time, it can prevent the accumulation of silicon carbide material and grinding balls from causing impact and friction, thereby affecting the grinding efficiency and effect.

[0046] Referring to Figures 8-10 The heat dissipation mechanism 4 comprises a heat dissipation channel 41 opened in the left and right sliding bar 311. The heat dissipation channel 41 comprises a left and right oriented pipe one and a plurality of pipe two symmetrically inclined and opened on the side of the pipe one away from the arc-shaped lining plate 211. The left and right adjacent pipe one is connected, and the right part of the rightmost pipe one is closed. The left end of the leftmost left and right sliding bar 311 is provided with a telescopic ventilation pipe 42 connected with the corresponding heat dissipation channel 41. The left end of the cylinder body 12 is externally sleeved with a circular ring pipe 43. The telescopic ventilation pipe 42 is detachably connected with the circular ring pipe 43 through the cylinder body 12. The left end of the cylinder body 12 is provided with a fan 44 connected with the circular ring pipe 43 through an L-shaped frame.

[0047] In use, the fan 44 ventilates the inside of the circular ring pipe 43. The wind flows into the heat dissipation channel 41 in the left and right sliding bar 311 through the telescopic ventilation pipe 42, and then flows from left to right through the pipe one in the left and right sliding bar 311, and then is blown out through the inclined pipe two. The wind blown out by the pipe two close to the inner wall of the cylinder body 12 changes direction under the reaction force of the cylinder body 12 and cools the arc-shaped lining plate 211. The wind blown out by the pipe two away from the inner wall of the cylinder body 12 directly blows to the convex outer wall of the arc-shaped lining plate 211 for cooling. It prevents the accumulation of heat on the arc-shaped lining plate 211, avoids the softening phenomenon caused by the reduction of hardness and wear resistance of the arc-shaped lining plate 211, and is more easily impacted and rubbed by the grinding ball and silicon carbide particles. It is noted that a one-way valve is arranged in the pipe two to prevent powder from entering the inside of the pipe two.

[0048] Referring to Figures 1-10The specific operation steps of the silicon carbide material ball mill device are as follows: when the wear-resistant mechanism 2 is installed in batches, the mounting column group 212 is inserted into the corresponding mounting hole group 16, the left-to-right row of arc-shaped lining plates 211 are installed through the mounting column group 212, the L-shaped locking rod one 221 is clamped into the corresponding clamping groove of the mounting column group 212 through the clamping strip 224, and the position of the mounting column group 212 is quickly locked; when the worn arc-shaped lining plate 211 needs to be maintained and replaced, the single arc-shaped lining plate 211 can be quickly disassembled through the adjusting screw 226.

[0049] In the grinding process, the silicon carbide material is conveyed into the cylinder 12 through the feeding port 13, the motor 151 drives the cylinder 12 to rotate, the grinding balls in the cylinder 12 serve as the grinding medium, repeatedly collide and rub with the silicon carbide material in the process of the rotation of the cylinder 12, the crushing and fine grinding of the silicon carbide material are realized, and the stably installed arc-shaped lining plate 211 protects the cylinder 12 from being worn in the grinding process.

[0050] Through the left-right reciprocating sliding movement of the wedge one 313 and the cooperation with the wedge two 33, the accumulation of the silicon carbide material and the grinding balls between the two rows of arc-shaped lining plates 211 is prevented, the fan 44 is used to ventilate the inside of the circular ring pipeline 43, the cold air flows into the heat dissipation channel 41 in the left-right sliding strip 311 through the telescopic ventilation pipe 42, the arc-shaped lining plate 211 is air-cooled and cooled, and the heat accumulation on the arc-shaped lining plate 211 is prevented.
