[0025] Embodiment 1 As Figure 1 shown, it is a flowchart of a method for preventing blockage of the graphite powder bin 230 with continuous feeding in the embodiments of the present application.

Specifically: ① The automatic sensing unit includes a fourth display screen 10, a fourth controller 11, a third distance measuring instrument 12, a fifth display screen 15, a fifth controller 16, and a fourth distance measuring instrument 17.

The seventh controller 26 is electrically connected to the seventh display screen 25 and the air cannons 22 arranged in the right half area of the graphite powder silo respectively, for controlling the air cannons in the right half area of the graphite powder silo to be kept in the closed or open state. The air cannons are arranged in three layers and are divided into left and right areas based on the center line of the graphite powder silo 230. Among them, the three - layer air cannons in the left and right areas can all achieve single - point control or linkage control.

[0029] ③ The automatic blanking unit includes an eighth display screen 30, an eighth controller 31, a fifth rangefinder 32, a blanking port 34 in the left half area, a first grinding and floating feeding belt 36, a ninth display screen 37, a ninth controller 38, a sixth rangefinder 39, and a second grinding and floating feeding belt 43.

The grinding and floating feeding belts are divided into left and right areas based on the midline of the graphite powder bin 230.

In this embodiment, the third rangefinder 12, the fourth rangefinder 17, the fifth rangefinder 32, and the sixth rangefinder 39 are preferably laser rangefinders, which can be specifically determined according to the actual situation, and this embodiment does not limit this.

[0030] (3) The graphite powder bin 230 includes a graphite powder bin wall 44 and a feeding inlet 45.

[0031] It can be understood that the first controller 2, the second controller 5, the third controller 8, the fourth controller 11, the fifth controller 16, the sixth controller 21, the seventh controller 26, the eighth controller 31, and the ninth controller 38 in this embodiment can be PLC controllers, such as PLC controllers of models CPM1, CPM1A, and CPM2AH, etc.; the first controller 2, the second controller 5, the third controller 8, the fourth controller 11, the fifth controller 16, the sixth controller 21, the seventh controller 26, the eighth controller 31, and the ninth controller 38 are all connected to the power supply line 46. The first display screen 1, the second display screen 4, the third display screen 7, the fourth display screen 10, the fifth display screen 15, the sixth display screen 20, the seventh display screen 25, the eighth display screen 30, and the ninth display screen 37 in this embodiment can be manual control screens, such as models A985GOT-TBA-V, PWS6600S-P, etc.

[0032] Specifically, as Figure 7 shown, first, the first preset distance value L0 and the first preset distance fluctuation value L1 between the height of the graphite powder in the graphite powder bin 230 and the feeding inlet 45 are set respectively through the second display screen 4 and the third display screen 7. Then, the first real-time distance value L2 between the height of the graphite powder in the graphite powder bin 230 and the feeding inlet 45 is collected by the first rangefinder 6 and the second rangefinder 9, and the first real-time distance value L2 is transmitted to the second controller 5 and the third controller 8.

[0033] Further, every t seconds, the second controller 5 and the third controller 8 receive the first real-time distance value L2 transmitted by the first distance measuring instrument 6 and the second distance measuring instrument 9, calculate the first distance difference ΔL = L2 - L0 between the first real-time distance value and the first preset distance value, compare the first distance difference ΔL with the first preset distance fluctuation value L1 to obtain the first comparison result, and transmit the first comparison result to the first controller 2. The first controller 2 controls the operation of the feeding belt according to the first comparison result, specifically as follows: (1) When the absolute value of the first distance difference is less than the first preset distance fluctuation value, it means that the height of the graphite powder is very close to the preset position and the fluctuation is within the allowable range. Therefore, the first controller 2 controls the feeding belt to stop working to avoid overfilling; (2) When the absolute value of the first distance difference is greater than the first preset distance fluctuation value and the first real-time distance value is less than the first preset distance value, it means that the height of the graphite powder is higher than the preset ideal height, but the exceeding degree exceeds the allowable fluctuation range. Therefore, the first controller 2 controls the feeding belt to stop working to prevent the further increase of the graphite powder; (3) When the absolute value of the first distance difference is greater than the first preset distance fluctuation value and the first real-time distance value is greater than the first preset distance value, it means that the height of the graphite powder is lower than the preset ideal height, and the lower degree exceeds the allowable fluctuation range. Therefore, the first controller 2 controls the feeding belt to start working to release some graphite powder to keep the height of the graphite powder within the preset range.

[0034] In this embodiment, the value of the first preset distance fluctuation value L1 is 3m, and the value of the signal time interval t for the second controller 5 and the third controller 8 to receive the first real-time distance value L2 transmitted by the first distance measuring instrument 6 and the second distance measuring instrument 9 is 10s. The specific data can be determined according to the actual situation, and this embodiment does not make any limitations on this.

[0035] Through the above method, the system can accurately control the filling amount of the graphite powder through the automatic distance measuring device, ensure that the graphite powder in the graphite powder bin remains at a stable level and always at the best stacking height, thereby improving the production efficiency and product quality, greatly increasing the automation degree of the production process, reducing manual intervention, and lowering the operation difficulty and labor cost.

[0036] Step S120: Collect the second real-time distance value between the graphite powder around the air cannon and the third distance measuring instrument and the fourth distance measuring instrument through the third distance measuring instrument and the fourth distance measuring instrument, compare the second real-time distance value with the second preset distance value to obtain the second comparison result, and control the operation of the air cannon according to the second comparison result.

[0037] Specifically, as Figure 8As shown in the figure, first, the second preset distance value LK0 and the second preset distance fluctuation value LK1 between the graphite powder around the air cannon and the third distance measuring instrument 12 and the fourth distance measuring instrument 17 are set through the fourth display screen 10 and the fifth display screen 15 respectively. The third distance measuring instrument 12 and the fourth distance measuring instrument 17 collect the second real-time distance value LK2 between the graphite powder around the air cannon in the graphite powder bin 230 and the third distance measuring instrument 12 and the fourth distance measuring instrument 17, and transmit the second real-time distance value LK2 to the fourth controller 11 and the fifth controller 16.

[0038] Further, the fourth controller 11 and the fifth controller 16 receive the second real-time distance value LK2 transmitted by the third distance measuring instrument 12 and the fourth distance measuring instrument 17 every t' seconds, calculate the second distance difference ΔLK = LK2 - LK0 between the second real-time distance value and the second preset distance value, compare the second distance difference ΔLK with the second preset distance fluctuation value LK1 to obtain the second comparison result, and transmit the second comparison result to the sixth controller 21 and the seventh controller 26. The sixth controller 21 and the seventh controller 26 control the operation of the air cannon according to the second comparison result, as follows: (1) When the absolute value of the second distance difference is less than the second preset distance fluctuation value, it means that the distance between the graphite powder around the air cannon and the third distance measuring instrument 12 and the fourth distance measuring instrument 17 is within the preset range. Therefore, the sixth controller 21 and the seventh controller 26 control the air cannon to stop working to avoid unnecessary energy consumption and possible equipment wear; (2) When the absolute value of the second distance difference is greater than the second preset distance fluctuation value and the second real-time distance value is less than the second preset distance value, it means that the distance between the graphite powder around the air cannon and the third distance measuring instrument 12 and the fourth distance measuring instrument 17 is relatively close, and it may be necessary to promote the flow of the graphite powder through the vibration of the air cannon to prevent blockage or affect the subsequent production process. Therefore, the sixth controller 21 and the seventh controller 26 control the air cannon to start working to improve the flow state of the graphite powder through the vibration effect; (3) When the absolute value of the second distance difference is greater than the second preset distance fluctuation value and the second real-time distance value is greater than the second preset distance value, it means that the distance between the graphite powder around the air cannon and the third distance measuring instrument 12 and the fourth distance measuring instrument 17 is higher than the preset range. At this time, the vibration of the air cannon is not required. Therefore, the sixth controller 21 and the seventh controller 26 control the air cannon to stop working.

[0039] In this embodiment, the value of the second preset distance fluctuation value LK1 is 2m, and the value of the signal time interval t' for the fourth controller 11 and the fifth controller 16 to receive the second real-time distance value LK2 transmitted by the third distance measuring instruments 12 - 14 and the fourth distance measuring instruments 17 - 19 is 10s. The specific data can be determined according to the actual situation, and this embodiment does not limit this.

[0040] Through precise ranging and real-time control, the above method ensures that the operation of the air cannon in the graphite powder silo can be intelligently adjusted according to the height of the graphite powder material, thereby improving the fluidity of the graphite powder material and the utilization efficiency of the silo. This automated control method not only improves work efficiency but also reduces the need for manual intervention and lowers operating costs.

[0041] In step S130, the third real-time distance values between the graphite powder material in the graphite powder silo and the fifth distance measuring instrument and the sixth distance measuring instrument are collected through the fifth distance measuring instrument and the sixth distance measuring instrument. The third real-time distance values are compared with the third preset distance values to obtain a third comparison result, and the operation of the grinding and floating feeding belt is controlled according to the third comparison result.

[0042] Specifically, as Figure 8 shown, first, the third preset distance value LX0 and the third preset distance fluctuation value LX1 between the graphite powder material and the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 are set through the eighth display screen 30 and the ninth display screen 37 respectively. The third real-time distance value LX2 between the graphite powder material in the graphite powder silo 230 and the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 is collected through the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39, and the third real-time distance value LX2 is transmitted to the eighth controller 31 and the ninth controller 38.

[0043] Furthermore, the eighth controller 31 and the ninth controller 38 receive the third real-time distance value LX2 transmitted by the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 every t'' seconds, calculate the third distance difference ΔLX = LX2 - LX0 between the third real-time distance value and the third preset distance value, compare the third distance difference ΔLX with the third preset distance fluctuation value LX1 to obtain a third comparison result, and control the operation of the grinding and floating feeding belt according to the third comparison result, specifically as follows: (1) When the absolute value of the third distance difference is less than the third preset distance fluctuation value, it means that the distance between the graphite powder material and the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 is relatively close, and the degree of closeness is within the preset fluctuation range. Therefore, the eighth controller 31 and the ninth controller 38 control the grinding and floating feeding belt to start working so that the graphite powder material continuously falls into the grinding and floating feeding belt through the feeding port; (2) When the absolute value of the third distance difference is greater than the third preset distance fluctuation value and the third real-time distance value is less than the third preset distance value, it means that the distance between the graphite powder material and the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 is very close, and the degree of closeness is greater than the preset fluctuation range. Therefore, the eighth controller 31 and the ninth controller 38 control the grinding and floating feeding belt to start working so that the graphite powder material continuously falls into the grinding and floating feeding belt through the feeding port; (3) When the absolute value of the third distance difference is greater than the third preset distance fluctuation value and the third real-time distance value is greater than the third preset distance value, it means that the distance between the graphite powder and the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 is not close enough, and the feeding port is in a void state. Therefore, the eighth controller 31 and the ninth controller 38 control the grinding and floating feeding belt to stop working.

[0044] In this embodiment, the third preset distance fluctuation value LX1 is set to 2m, and the time interval t'' between the eighth controller 31 and the ninth controller 38 receiving the signal of the third real-time distance value LX2 transmitted by the fifth distance measuring instrument 32 and the sixth distance measuring instrument 39 is set to 10s. The specific data can be determined according to the actual situation and is not limited in this embodiment.

[0045] The above method accurately controls the operation of the grinding and floating feeding belt, enables the graphite powder to continuously fall into the grinding and floating feeding belt through the feeding port, prevents large-scale changes in the pulp concentration caused by the interruption of ore feeding on the grinding and floating feeding belt, thereby avoiding self-wear of the nodular graphite equipment caused by ore interruption, greatly stabilizing the production index, avoiding the idling operation of the grinding and floating feeding belt, improving the effective utilization rate of the equipment, reducing the operating energy consumption, and effectively avoiding the loss caused by the idling of the equipment.
