[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present application, the special design of the conveying pipe structure cooperates with the transport force provided by the high-speed airflow output by the high-speed fan to separate and collect large particles in the graphite dust. The large particles fall into the inside of the sedimentation box through the square groove. An arc-shaped detection member is arranged at the bottom of the inner cavity of the sedimentation box. The large particles fall into the inside of the arc-shaped detection member. The arc-shaped detection member is composed of an arc-shaped frame and an elastic member fixedly installed inside the arc-shaped frame. The large particles fall into the inside of the elastic member, and the elastic member is deformed by the weight of the large particles. The liquid hydraulic pressure between the elastic member and the arc-shaped frame changes. The staff can judge the quality of the graphite grinding processing of the graphite processing structure according to the detection results of the hydraulic sensor, and can timely judge the processing quality according to the processed graphite powder when using a pneumatic conveying structure with good sealing performance, and can timely and flexibly control and adjust the work of the graphite processing structure.

[0016] 2. In the present application, when the high-speed fan conveys air flow into the conveying pipe, the air flow and graphite dust will collide with the upwardly inclined position of the inner wall of the conveying pipe, and then the air flow and graphite dust will move upward. At this time, the air flow velocity decreases during the process, and under the action of impact and gravity, large particles in the graphite dust fall down and then fall into the sedimentation box through the square groove. Through the special design of the conveying pipe structure and the transportation force provided by the high-speed airflow output by the high-speed fan, the large particles in the graphite dust are separated and collected, thereby shortening the graphite dust processing cycle.

[0017] 3. In the present application, the arc-shaped detection component isolates the semicircular space at the bottom of the inner cavity of the sedimentation box from the inside of the conveying pipe. At this time, the arc-shaped detection component and the sedimentation box cooperate to build a sealed circular channel between the air guide pipe four and the solenoid valve three. Large particles are inside the circular channel. The positive and negative motors drive the inner hexagonal tube to rotate. The inner hexagonal tube drives the threaded rod to rotate through the outer hexagon. The rotating threaded rod rotates and displaces under the influence of the threaded structure between the air guide pipe four. The threaded rod drives the hydraulic sensor and the arc-shaped detection component to rotate and displace in the direction away from the solenoid valve three. The high-speed fan conveys high-speed airflow to the inside of the reflux channel composed of the air guide pipe three, the cylinder body, the air guide pipe four, the sedimentation box, the solenoid valve three and the air guide pipe five through the air guide pipe one, the three-way valve, the cylinder body, the air guide pipe four, the sedimentation box, the solenoid valve three and the air guide pipe five. The large particles inside the circular channel are located on the flow path of the high-speed airflow. The large particles that are stirred and dispersed by the rotating arc-shaped detection component are transported back to the grinding equipment by the high-speed airflow, so that the rework of the large particles can be completed, the graphite processing cycle can be shortened, and the participation of staff can be reduced.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: Figure 1-Figure 15 As shown, the present invention provides a technical solution for a pneumatic collection and transportation device for graphite processing dust: Specifically, the grinding equipment 11 in the graphite processing structure 1 is responsible for grinding and processing graphite. The solenoid valve 12 installed at the feed port of the grinding equipment 11 and the feed hopper 13 fixedly installed on the top control the solenoid valve 12 to work and open, so that graphite can be added to the grinding equipment 11 through the feed hopper 13, and the solenoid valve 2 14 fixedly installed between the discharge end of the grinding equipment 11 and the conveying pipe 21 is controlled to work and open, and the graphite powder ground by the grinding equipment 11 falls into the conveying pipe 21 through the solenoid valve 2 14.

[0022] Specifically, a fixing frame 23 is fixedly installed between the high-speed fan 22 and the conveying pipe 21, the high-speed fan 22 is fixedly installed on one side of the conveying pipe 21, an air guide pipe 24 is fixedly installed between the air outlet end of the high-speed fan 22 and the three-way valve 25, and an air guide pipe 26 is fixedly installed between the normally open end of the three-way valve 25 and the expansion pipe 27, and the expansion pipe 27 is fixedly connected to the side of the conveying pipe 21 away from the conveying and collecting structure 3. After the high-speed fan 22 is controlled to work, the high-speed fan 22 injects a high-speed airflow into the conveying pipe 21 through the air guide pipe 24, the three-way valve 25, the air guide pipe 26 and the expansion pipe 27, and the airflow blows the graphite powder falling into the conveying pipe 21. , and one end of the conveying pipe 21 is fixedly connected with the top of the collecting box 31, so the graphite powder is conveyed to the inside of the collecting box 31, and a fixing frame 32 is fixedly installed between the top of the filter bag 33 and the top of the inner cavity of the collecting box 31, the bottom end of the conveying pipe 21 is connected with the inside of the fixing frame 32, and the outer wall of the fixing frame 5 34 fixedly installed at the bottom of the filter bag 33 is fixedly connected with the inside of the collecting box 31. At this time, the bottom of the fixing frame 5 34 is sealed by the cleaning transmission assembly, so the graphite powder blown by the airflow enters the inside of the filter bag 33, and the graphite powder in the airflow is trapped in the filter bag 33. The high-speed fan 22 continues to work to perform the pneumatic conveying work of the graphite powder output by the grinding equipment 11; Because one end of the exhaust pipe 223 fixedly installed at the air inlet end of the high-speed fan 22 is arranged on the top of the fixed frame 5 34, the high-speed fan 22 extracts the filtered and purified gas from the inside of the collecting box 31 through the exhaust pipe 223, and then the high-speed fan 22 pressurizes the gas to transport the graphite powder to the inside of the conveying and collecting structure 3. Clean gas is used to transport the graphite powder processed by the graphite processing structure 1, thereby reducing the contamination of the graphite powder during pneumatic transportation, reducing the cost investment required for the operation of the high-speed fan 22, and ensuring the quality of graphite powder processing.

[0023] Specifically, an air intake bend pipe 331 is fixedly installed at one end of the solenoid valve four 330 fixedly installed on the top of the collection box 31, and a filter net 332 fixedly installed inside the air intake bend pipe 331 plays a filtering role. After the solenoid valve four 330 is controlled to open, the air filtered by the filter net 332 enters the grinding equipment 11, and the air pressure inside the collection box 31 and the conveying pipe 21 is controlled to avoid the occurrence of a more extreme air pressure environment.

[0024] Specifically, an air guide pipe 3 28 is fixedly installed between the cylinder body 29 and the normally closed end of the three-way valve 25, an air guide pipe 4 210 is fixedly installed between the cylinder body 29 and the sedimentation box 211, an electromagnetic valve 3 212 is fixedly installed on the side of the sedimentation box 211 away from the air guide pipe 4 210, and an air guide pipe 5 213 is fixedly installed between the electromagnetic valve 3 212 and the grinding equipment 11. A reflux channel is formed by the air guide pipe 3 28, the cylinder body 29, the air guide pipe 4 210, the sedimentation box 211, the electromagnetic valve 3 212 and the air guide pipe 5 213. When the electromagnetic valve 3 212 is not working and is in a closed state, the hydraulic sensor 215 is inserted on the sedimentation box 211, and the sedimentation box 211 is fixedly installed at the bottom of the conveying pipe 21 and is arranged at the bottom of the square groove 222. The square groove 222 is arranged on one side of the bottom of the inner wall of the bend of the conveying pipe 21. At this time, the interior of the sedimentation box 211 is only connected with the interior of the conveying pipe 21. When the high-speed fan 22 conveys air flow into the conveying pipe 21, the air flow and graphite dust will collide with the upwardly inclined position of the inner wall of the conveying pipe 21, and then the air flow and graphite dust move upward. At this time, the air flow velocity decreases in the process, and under the action of collision and gravity, large particles in the graphite dust fall down and fall into the sedimentation box 211 through the square groove 222. Through the special design of the structure of the conveying pipe 21 and the transportation force provided by the high-speed airflow output by the high-speed fan 22, the large particles in the graphite dust are separated and collected, thereby shortening the graphite dust processing cycle.

[0025] The present application forms a pneumatic conveying and collecting device for conveying graphite dust processed by the graphite processing structure 1 through the pneumatic conveying structure 2 and the conveying and collecting structure 3. The specific working principle is as follows: When the grinding equipment 11 is controlled to work and the internal graphite is ground, the solenoid valve 2 14 is controlled to work and open, and the graphite dust enters the inside of the conveying pipe 21, and the high-speed fan 22 is controlled to work. The high-speed fan 22 conveys the graphite dust to the inside of the conveying pipe 21 through the air guide pipe 1 24, the three-way valve 25, the air guide pipe 2 26 and the expansion pipe 1 27, and blows the graphite dust inside the conveying pipe 21 to the inside of the conveying and collecting structure 3 to perform pneumatic conveying.

[0026] After the above-mentioned pneumatic conveying work is carried out for a period of time, the high-speed fan 22 is controlled to stop working for a period of time, so that the airflow inside the conveying pipe 21 stops flowing. Under the cooperation of the special design of the conveying pipe 21 structure and the transport force provided by the high-speed airflow output by the high-speed fan 22, the large particles in the graphite dust are separated and collected, and the large particles fall into the sedimentation box 211 through the square groove 222. An arc-shaped detection member 214 is arranged at the bottom of the inner cavity of the sedimentation box 211, and the large particles fall into the arc-shaped detection member 214. The arc-shaped detection member 214 is composed of an arc frame 2141 and an elastic member 21 fixedly installed inside the arc frame 2141. 42, large particles fall into the elastic member 2142, the elastic member 2142 is deformed by the weight of the large particles, the liquid hydraulic pressure between the elastic member 2142 and the arc frame 2141 changes, the hydraulic sensor 215 detects the liquid hydraulic pressure change and feeds back to the human-computer interaction device, the staff can judge the quality of the graphite grinding processing by the graphite processing structure 1 according to the detection result of the hydraulic sensor 215, and when the pneumatic conveying structure 2 with better sealing performance is used, the processing quality can be judged in time according to the processed graphite powder, and the operation of the graphite processing structure 1 can be controlled and adjusted in time and flexibly.

[0027] When a batch of graphite is processed, the forward and reverse motor 220 in the control drive assembly works for a period of time. Since the inner hexagonal tube 219 is fixedly installed at the output end of the forward and reverse motor 220, the outer hexagon 218 is fixedly installed at one end of the threaded rod 216 fixedly installed on one side of the hydraulic sensor 215. The polygonal outer hexagon 218 is arranged inside the inner hexagonal tube 219 and can rotate synchronously with the inner hexagonal tube 219. At the same time, the outer hexagon 218 can move inside the inner hexagonal tube 219, and the threaded rod 216 One end passes through the air guide pipe 210 and is threadedly connected to the air guide pipe 210. The fixing frame 221 fixedly installed on the top of the collection box 31 is fixedly connected to the forward and reverse motor 220, so the forward and reverse motor 220 cannot move. After the forward and reverse motor 220 is controlled to work forward, the forward and reverse motor 220 drives the inner hexagonal tube 219 to rotate, and the inner hexagonal tube 219 drives the threaded rod 216 to rotate through the outer hexagonal body 218. The rotating threaded rod 216 is affected by the thread structure between the air guide pipe 210 and the second fixing frame 221 fixedly installed on the top of the collection box 31. The threaded rod 216 drives the hydraulic sensor 215 and the arc detection member 214 to rotate and move in a direction away from the electromagnetic valve 3 212, and the end of the arc detection member 214 away from the hydraulic sensor 215 extends to the inside of the electromagnetic valve 3 212. Therefore, after the forward and reverse motor 220 stops working, the end of the arc detection member 214 close to the electromagnetic valve 3 212 moves to align with the side wall of the inner cavity of the sedimentation box 211, and the hydraulic sensor 215 moves away from the inside of the gas guide pipe 4 210. A distance from the sedimentation box 211, the interior of the air guide pipe 210 is connected with the interior of the sedimentation box 211, and the arc-shaped detection member 214 stays at a position rotated 180° compared with the initial position, and the arc-shaped detection member 214 isolates the semicircular space at the bottom of the inner cavity of the sedimentation box 211 from the interior of the conveying pipe 21. At this time, the arc-shaped detection member 214 and the sedimentation box 211 cooperate to build a sealed circular channel between the air guide pipe 210 and the electromagnetic valve 3 212, and the large particles are inside the circular channel; Then the high-speed fan 22 is controlled to work, the normally closed end of the three-way valve 25 is controlled to open, and the solenoid valve three 212 is controlled to work and open. At this time, the high-speed fan 22 conveys high-speed airflow to the inside of the reflux channel composed of the air guide pipe one 24, the three-way valve 25, the air guide pipe three 28, the cylinder body 29, the air guide pipe four 210, the sedimentation box 211, the solenoid valve three 212 and the air guide pipe five 213, and the large particles inside the circular channel are located on the flow path of the high-speed airflow. The large particles that are stirred and broken up by the rotating arc-shaped detection part 214 are conveyed back to the inside of the grinding equipment 11 by the high-speed airflow, so that the rework of the large particles can be completed, the graphite processing cycle can be shortened, and the participation of staff can be reduced.

[0028] During the reworking of large particles, at the initial stage, since the gear ring 1 36 fixedly installed inside the rotating frame 35 in the cleaning transmission assembly is meshed with a gear 333 on one side, the gear 333 is fixedly connected with a transmission shaft 1 317 inside, and the top of the transmission shaft 1 317 is fixedly connected to the output end of the gear box 318 fixedly installed on the conveying pipe 21, and the input end of the gear box 318 is fixedly installed with an impeller 319, which is rotatably installed on the cylinder body 29. Therefore, when the high-speed airflow flows through the cylinder body 29, the impeller 319 is The high-speed airflow drives the rotating shaft 318 to rotate, and the gear box 318 changes the speed and direction of the rotating force delivered by the impeller 319 and transmits it to the transmission shaft 1 317. The two ends of the transmission shaft 1 317 respectively penetrate the top of the collection box 31 and the fixed frame 5 34. The transmission shaft 1 317 is rotatably connected with the fixed frame 5 34 and the collection box 31. The transmission shaft 1 317 rotates on itself, and the transmission shaft 1 317 applies the rotating force to the rotating frame 35 through the gear ring 1 36 and the gear 3 333. The rotating frame 35 rotates, and the multiple push plates 37 fixedly installed inside the rotating frame 35 rotate. The plurality of fixing frames 6 38 on one side of the plurality of pushing plates 37 are all fixedly mounted on the fixing frame 5 34, and a fixing frame 7 310 is fixedly mounted on the side of the rotating plate 39 rotatably mounted on the fixing frame 6 38 close to the inner wall of the collecting box 31, and a roller 311 rotatably mounted on the fixing frame 7 310 is arranged on the rotating movement path of the pushing plate 37. Therefore, during the movement of the pushing plate 37, the wheel composed of the roller 311 and the fixing frame 7 310 pushes the rotating plate 39 to rotate and tilt, so that the plurality of knocking rods 312 fixedly mounted on the side of the rotating plate 39 close to the filter bag 33 move away from the filter bag 33; and a fixing frame 8 313 is provided on the side of the rotating plate 39 close to the filter bag 33, and a fixing frame 9 315 is fixedly mounted between the plurality of spring-type telescopic rods 314 fixedly mounted on one side of the fixing frame 8 313, and the fixing frame 9 315 is fixedly mounted on the fixing frame 5 34 and cannot move. When the pushing plate 37 pushes the rotating plate 39 under the action of the wheel, the bottom end of the rotating plate 39 pushes The movable fixed frame eight 313 moves, and the multiple spring-type telescopic rods 314 contract and accumulate force. After the pushing plate 37 moves out of contact with the wheel, the rebounded multiple spring-type telescopic rods 314 push the fixed frame eight 313 to reset, and the rotating plate 39 is reset by force. The multiple knocking rods 312 fixedly installed on the rotating plate 39 knock the filter bag 33, and multiple positions of the filter bag 33 are knocked by the multiple knocking rods 312. The knocking rods 312 vibrate over a large area, so that the graphite powder attached to the inner wall of the filter bag 33 is shaken off, and the exhaust pipe 223 draws air from the top of the fixed frame five 34. The fixed frame five 34 is located at the bottom of the filter bag 33, so the air inside the collection box 31 is in a state of flowing from top to bottom as a whole, increasing the speed at which the graphite powder inside the filter bag 33 gathers to the bottom of the inner cavity of the filter bag 33, and using the force generated by blowing large particles into the grinding equipment 11, the outside of the filter bag 33 is knocked, thereby ensuring the speed at which the graphite powder inside the filter bag 33 falls and is collected in a concentrated manner.

[0029] When the rework of large particles reaches the later stage, the solenoid valve 4 330 can be controlled to open, and the filtered outside air can be added to the collection box 31. The solenoid valve 12 can be controlled to open, so that the inside of the feed hopper 13 is connected to the inside of the grinding equipment 11, and the solenoid valve 2 14 can be controlled to be closed, so that the grinding equipment 11 can only be connected to the outside through the solenoid valve 12 and the feed hopper 13; that is, graphite can be added to the inside of the grinding equipment 11 through the feed hopper 13. At this time, the high-speed fan 22 conveys airflow to the inside of the grinding equipment 11 through the air guide duct 124, the three-way valve 25, and the reflux channel. The air pressure inside the grinding equipment 11 is much higher than that of the outside world, so the grinding equipment 11 discharges high-speed airflow to the outside world through the solenoid valve 12 and the feed hopper 13, so as to prevent external impurities from entering the inside of the grinding equipment 11 along with the addition of graphite, thereby ensuring the cleanliness of the inside of the grinding equipment 11.

[0030] In addition, a mounting frame 2 329 is fixedly installed at the bottom of the fixing frame 5 34, and a transmission shaft 2 327 is fixedly installed inside the mounting frame 2 329 and the electromagnet part 3 328 rotatably connected therein. The part of the bottom end of the transmission shaft 1 317 extending into the inside of the electromagnet part 3 328 is made of iron, so after the control electromagnet part 3 328 is operated, the electromagnet part 3 328 is adsorbed and fixed to the transmission shaft 1 317 by magnetic force, and the transmission shaft 1 317 rotates and drives the transmission shaft 2 327 to rotate through the electromagnet part 3 328, and the gear 2 326 fixed at the bottom end of the transmission shaft 2 327 rotates; Since the gear 1 321 is arranged at the bottom of the discharge hopper 320 and contacts the discharge hopper 320, the gear 1 321 seals the bottom of the discharge hopper 320 and is fixedly connected to the fixed frame 5 34. A mounting shaft 323 is fixedly installed on the top of the gear 1 321. The outer side of the mounting shaft 323 is rotatably installed with an electromagnet part 2 324 and a mounting frame 1 325. The mounting frame 1 325 is fixedly connected to the discharge hopper 320 and cannot move. The electromagnet part 2 324 is fixedly installed inside the mounting frame 1 325 and cannot move. Under normal conditions, the second electromagnet part 324 is in working condition, and the second electromagnet part 324 fixes the internal iron mounting shaft 323 by magnetic force, and the gear 1 321 is limited and cannot move, so that the gear 1 321 can stably seal the bottom of the discharge hopper 320.

[0031] In the process of feeding graphite into the grinding equipment 11, the electromagnet part 1 316 is first controlled to work. At this time, the electromagnet part 1 316 adsorbs and fixes the iron fixing frame 8 313, the spring-type telescopic rod 314 maintains a contracted state, the rotating plate 39 is no longer reset, and the filter bag 33 is no longer struck. Then the electromagnet part 328 is controlled to work for a period of time, and the electromagnet part 2 324 is controlled to stop working for a period of time. During this process, the gear 2 326 rotates to drive the meshing gear 1 321 to rotate, the gear 1 321 rotates 90°, and one of the two discharge holes 322 opened in the gear 1 321 is aligned with the bottom of the discharge hopper 320. At this time, the graphite powder inside the filter bag 33 falls through the discharge hopper 320 and the discharge hole 322, so that the graphite powder falls to the collection structure pre-arranged at the bottom of the gear 1 321 and abuts against the bottom of the gear 1 321, thereby completing the unloading of the graphite powder.

[0032] Then, the electromagnet part three 328 is controlled to work for a period of time again, so that the gear one 321 rotates 90 degrees again, so that the gear one 321 seals the bottom of the discharge hopper 320, and finally the electromagnet part two 324 is controlled to limit the gear one 321, the high-speed fan 22 is controlled to stop working, and the pneumatic conveying structure 2 and the conveying and collecting structure 3 are controlled to work and return to the initial state.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
