They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] like Figure 1 As shown, in this embodiment, the pipe surface grinding and dust removal system includes a grinding assembly, a circulating spray mechanism, and a dust removal mechanism. The grinding assembly includes a base 1, a grinding machine 2, and a clamping mechanism. The clamping mechanism is located on the base 1 and is used to clamp the pipe 100. The grinding machine 2 is located on the base 1 and is used to grind the pipe 100. The circulating spray mechanism includes a water tank 3, a spray pipe 4, and a wastewater treatment module. The water tank 3 is connected to the spray pipe 4, which is located above the grinding assembly. The base 1 has a drain outlet 5, which is connected to the inlet of the wastewater treatment module. The outlet of the wastewater treatment module is connected to the water tank 3. The dust removal mechanism includes an axial flow fan 6 and a negative pressure pipe 7. The suction port of the negative pressure pipe 7 is located below the grinding assembly, and the outlet of the negative pressure pipe 7 is connected to the axial flow fan 6. The axial flow fan 6 is used to discharge water-curtain-treated air outdoors.

[0031] For example, the grinding components, spray pipe 4, and dust removal mechanism are located inside the factory building to avoid polluting the outdoor air. The wastewater treatment module is located underground in the factory building, so that wastewater can enter the wastewater treatment module for purification by its own gravity. The water tank 3 is located outside the factory building, serving both to store the treated wastewater and to connect to an external water source.

[0032] A grinding machine 2 and a clamping mechanism are installed on the base 1. The pipe fitting 100 to be ground is clamped and fixed by the clamping mechanism. The clamping mechanism can move the pipe fitting 100 to the working area of ​​the grinding machine 2. The grinding sand belt of the grinding machine 2 grinds the pipe fitting 100. The ground pipe fitting 100 itself can generate jet particles, dust particles, large particles and fine suspended particles.

[0033] The water supply end of water tank 3 is connected to spray pipe 4 via a pipe. Water tank 3 supplies water to spray pipe 4, which sprays water onto the grinding assembly. This water mixes with the sprayed particles, dust particles, large particles, and fine suspended particles generated by the pipe fitting 100, forming a liquid mixture that falls onto base 1. A wastewater treatment module is located below base 1. The drain outlet 5 of base 1 is connected to the wastewater treatment module via a pipe. The liquid mixture flows into the wastewater treatment module through drain outlet 5, where it settles and treats the mixture into clean water. In other words, various particles generated during the grinding of pipe fitting 100 are flushed to the wastewater treatment module by the water flow, improving the dust removal effect during the grinding process. The wastewater treatment module is connected to water tank 3 via a pipe. Clean water enters water tank 3 through the pipe for storage and recycling, while separately separated particulate residue is collected for easy disposal.

[0034] The outlet of the axial flow fan 6 extends to the outside of the factory building, and the inlet of the axial flow fan 6 is connected to one end of the negative pressure pipe 7. The dust suction port at the other end of the negative pressure pipe 7 faces the pipe fitting 100, and the air velocity at the dust suction port must reach 23m. 3 According to the requirements of / S, the operating noise of the axial flow fan 6 must be less than 80 decibels. Under the negative pressure of the axial flow fan 6, the negative pressure pipe 7 can draw in the air treated by the water curtain of the spray pipe 4 through the dust suction port and discharge it outdoors through the axial flow fan 6, further improving the dust removal effect during the grinding process of the pipe fittings 100 and ensuring that the air quality around the equipment is always good.

[0035] It should be noted that the suction port is located on the lower side of the pipe 100 and only adsorbs air treated by the water curtain. Because the base 1 and the suction port are vertically offset, other types of particles mixed with water generated by the pipe 100 will not enter the suction port. The base 1 is located directly below the pipe 100, and the particles are directly sprinkled onto the base 1 and discharged through the drain port 5.

[0036] The working process of the pipe surface grinding and dust removal system is as follows: The clamping mechanism moves the clamped pipe 100 to the working area of ​​the grinding machine 2. The grinding machine 2 starts and grinds the pipe 100. At the same time, the water tank 3 supplies water to the spray pipe 4, which sprays water onto the pipe 100 and its surroundings. The water mixes with the sprayed particles, dust particles, large particles, and fine suspended particles generated during the grinding of the pipe 100, forming a mixture that falls onto the base 1. The mixture flows into the wastewater treatment module through the drain outlet 5. The wastewater treatment module treats the liquid mixture into clean water, which is then stored in the water tank 3 for recycling. The air treated by the water curtain of the spray pipe 4 is drawn into the dust suction port of the negative pressure pipe 7 under the negative pressure of the axial flow fan 6 and discharged outdoors through the axial flow fan 6. This improves the dust removal effect during the grinding process of the pipe 100, ensures that the air quality around the equipment remains good, and requires no manual operation, reducing the labor intensity of production personnel and improving production efficiency.

[0037] Furthermore, referring to Figure 1 The circulating spray mechanism also includes a spray pipe 8, the inlet end of which is connected to the water tank 3, and the outlet end of which faces horizontally toward the surface of the base 1, for washing away dust on the base 1 and flowing into the drain outlet 5. The sewage treatment module includes a sedimentation tank 9 and a sewage processor 10, the inlet end of which is connected to the drain outlet 5, the outlet end of which is connected to the sewage processor 10, and the sewage processor 10 is connected to the water tank 3.

[0038] The inlet of the spray pipe 8 is connected to the water tank 3, and the outlet of the spray pipe 8 is located at the end of the base 1 furthest from the drain outlet 5, with the axis of the outlet of the spray pipe 8 parallel to the horizontal plane of the base 1. When the water sprayed by the spray pipe 4 mixes with the particles generated by the ground pipe fitting 100 to form a mixture, it falls onto the base 1. The spray pipe 8 sprays water onto the base 1, causing the mixture to be flushed to the drain outlet 5. Through the drain outlet 5, it flows into the sedimentation tank 9. After sedimentation in the sedimentation tank 9, the wastewater enters the wastewater processor 10 through a pipe, while the settled particulate impurities remain in the sedimentation tank 9 for collection. The wastewater processor 10 purifies the wastewater, and the purified water flows through a pipe into the water tank 3 for storage and circulation.

[0039] Furthermore, referring to Figure 1 The circulating sprinkler system also includes a water supply pipe 11, a level sensor 12, and a level alarm 13. The water supply pipe 11 is connected to an external water source and connected to a water tank 3. Both the level sensor 12 and the level alarm 13 are located inside the water tank 3. The level sensor 12 is electrically connected to the valve of the water supply pipe 11. When the level sensor 12 detects that the liquid level in the water tank 3 is lower than a set value, the valve of the water supply pipe 11 opens and automatically replenishes water to the water tank 3. When the level sensor 12 detects that the liquid level in the water tank 3 is lower than the minimum value, the level alarm 13 sounds an alarm.

[0040] The level sensor 12 is electrically connected to the control circuit board, which controls the valve of the water supply pipe 11, the level alarm 13, and the start / stop of the grinder 2. When the level sensor 12 detects that the level in the water tank 3 is lower than the set value due to wear and tear, the level sensor 12 sends a high-level signal to the control circuit board, which then controls the valve of the water supply pipe 11 to open, allowing an external water source to automatically replenish the water tank 3 through the water supply pipe 11. When the level sensor 12 detects that the level in the water tank 3 meets the set value, the level sensor 12 sends a low-level signal to the control circuit board, which then controls the valve of the water supply pipe 11 to close, preventing an external water source from replenishing the water tank 3 through the water supply pipe 11. It should be noted that when the liquid level sensor 12 detects that the liquid level in the water tank 3 is lower than the minimum value, the liquid level sensor 12 sends a high level to the control circuit board. The control circuit board can control the liquid level alarm 13 to turn on and issue an alarm. At the same time, the control circuit board can control the grinder 2 to stop, so that the staff can add water and perform maintenance. The operation can only be started after the maintenance is completed.

[0041] Furthermore, referring to Figure 1 The circulating spraying mechanism also includes a water pump 14, which is installed in the water tank 3 and connected to the spray pipe 4. The water pump 14 is used to send the water in the water tank 3 to the spray pipe 4.

[0042] The water pump 14 is installed at the bottom of the water tank 3, with the inlet of the water pump 14 facing the bottom of the water tank 3, and the outlet of the water pump 14 connected to the spray pipe 4 through a pipe. The water pump 14 draws clean water from the water tank 3 and pumps the water through the pipe to the spray pipe 4 under its own pumping action, so that the spray pipe 4 can spray under high pressure.

[0043] Furthermore, referring to Figure 1 The dust removal system for pipe surface grinding also includes an exhaust mechanism located above the grinding assembly. The exhaust mechanism includes an exhaust fan 15, a dust concentration monitor 16, and a hydrogen concentration monitor 17. The dust concentration monitor 16 and the hydrogen concentration monitor 17 are both electrically connected to the exhaust fan 15. The dust concentration monitor 16 and the hydrogen concentration monitor 17 are used to monitor the dust concentration and hydrogen concentration around the grinding assembly, respectively. The exhaust fan 15 is used for exhaust and air exchange.

[0044] Both dust concentration monitor 16 and hydrogen concentration monitor 17 are electrically connected to the control circuit board. The control circuit board can control the start and stop of the exhaust fan 15 and the grinding machine 2. When the dust concentration monitor 16 detects that the dust concentration around the grinding components is higher than the warning value, or the hydrogen concentration monitor 17 detects that the hydrogen concentration around the grinding components is higher than the warning value, the dust concentration monitor 16 or the hydrogen concentration monitor 17 sends a high-level signal to the control circuit board. The control circuit board can then control the exhaust fan 15 to turn on and simultaneously control the grinding machine 2 to stop. The exhaust fan 15 extracts the excessive polluted air from the factory room to reduce the indoor dust and hydrogen concentrations and ensure that the air quality meets the standards. When the dust concentration monitor 16 detects that the dust concentration around the grinding components is lower than the warning value, and the hydrogen concentration monitor 17 detects that the hydrogen concentration around the grinding components is lower than the warning value, the dust concentration monitor 16 or the hydrogen concentration monitor 17 sends a low-level signal to the control circuit board, the alarm is cleared, and the equipment can be started for production operations.

[0045] Furthermore, referring to Figure 1 The dust removal mechanism also includes an emission particle detector 18, which is located at the outlet of the axial flow fan 6 and is used to detect the dust particle value emitted by the axial flow fan 6.

[0046] The particulate emission detector 18 is electrically connected to the control circuit board, which controls the start and stop of the grinder 2. When the particulate emission detector 18 detects that the dust particle value emitted by the axial flow fan 6 exceeds the limit, the particulate emission detector 18 sends a high-level signal to the control circuit board, which then controls the grinder 2 to stop until maintenance is completed. When the particulate emission detector 18 detects that the dust particle value emitted by the axial flow fan 6 does not exceed the limit, the particulate emission detector 18 sends a low-level signal to the control circuit board, which then controls the grinder 2 to start.

[0047] Furthermore, referring to Figure 1 The dust removal mechanism also includes a baffle plate 19, which is inclinedly arranged at the dust suction port of the negative pressure pipe 7.

[0048] The baffle 19 is inclined inward relative to the dust suction port. Under the action of the baffle 19, some of the fine suspended particles generated by the pipe 100 are not absorbed by the dust suction port, but drift to the bottom of the spray pipe 4 and mix with the water sprayed by the spray pipe 4 and fall onto the base 1. Finally, they are discharged into the sedimentation tank 9 through the drain outlet 5.

[0049] Furthermore, referring to Figure 1 The clamping mechanism includes a robotic arm 20 and a gripper 21. The robotic arm 20 is rotatably mounted on the base 1, and the gripper 21 is mounted on the robotic arm 20 and used to clamp the pipe fitting 100.

[0050] The robotic arm 20 is configured as a six-degree-of-freedom robot arm, typically composed of six rotary joints, each providing one degree of freedom. When combined, they enable flexible movement of the end effector. The robotic arm 20 can achieve any position and orientation relative to the base 1 in three-dimensional space. The gripper 21 holds the pipe 100. Under the action of the robotic arm 20, the gripper 21 and the pipe 100 it holds are moved to the working area of ​​the grinding machine 2, facilitating grinding of the pipe 100 by the grinding machine 2.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
