Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber manufacturing, and in particular to a pipeline foreign matter cleaning device, a pipeline system, and a pipeline foreign matter cleaning method. BACKGROUND

[0002] Currently, in the process of manufacturing optical fiber preforms by using the VAD method or the OVD method, a gas with acidity and toxicity needs to be used, so it is circulated in a pipeline with relatively high sealing performance. However, with the use and changes in the environment and temperature outside the pipeline, some foreign matters or rust powder will be deposited on the inner wall of the pipeline. With the increase of time, the deposition in the pipeline wall will be more and more, which will cause the pipeline diameter to become smaller or cause the pipeline and components such as valves and filters on the pipeline to be blocked, causing the circulation of the acidic and toxic gas to be poor, resulting in product defects, loose body cracking, or production interruption, and affecting normal production.

[0003] In the related art, the usual practice is to stop for a long time, remove the acidic and toxic gas remaining in the pipeline, and then disassemble the pipeline to clean or replace the blocked components.

[0004] However, the cleaning method in the related art usually takes a week or even longer, which is quite time-consuming for production, affects production efficiency, and also has the risk of contacting corrosive, acidic, and toxic gases. SUMMARY

[0005] The embodiments of the present application provide a pipeline foreign matter cleaning device, a pipeline system, and a pipeline foreign matter cleaning method to solve the problem of time-consuming production, affecting production efficiency, and the risk of contacting corrosive, acidic, and toxic gases in the related art.

[0006] On the one hand, the present application provides a pipeline foreign matter cleaning device, which adopts the technical scheme of:

[0007] A pipeline foreign matter cleaning device, comprising:

[0008] A cleaning device configured to be arranged in a transition branch connected to the pipeline;

[0009] A vacuum pumping mechanism configured to be connected to the transition branch;

[0010] A control module configured to, when the flow in the pipeline does not meet the setting, control the vacuum pumping mechanism to pump vacuum in the transition branch after the current deposition process is completed, open the control valve between the pipeline and the transition branch, and move the cleaning device in the pipeline to clean the pipeline.

[0011] In some embodiments, the foreign matter cleaning assembly is further configured to clean the foreign matters in the transition branch.

[0012] In some embodiments, the foreign matter cleaning assembly comprises:

[0013] an air inlet pipe connected to the transition branch and provided with a first valve;

[0014] an air outlet pipe connected to the transition branch and provided with a second valve;

[0015] a filtering assembly connected to the air outlet pipe for filtering the mixed gas discharged from the air outlet pipe.

[0016] In some embodiments, a driving mechanism is further provided outside the pipe for driving the cleaning device to move in the pipe.

[0017] In a second aspect, the present application further provides a pipe system, comprising:

[0018] a pipe;

[0019] a transition branch connected to the pipe;

[0020] a control valve provided between the transition branch and the pipe;

[0021] a cleaning device provided in the transition branch;

[0022] a vacuumizing mechanism connected to the transition branch;

[0023] a control module for, when the flow in the pipe does not meet the setting, controlling the vacuumizing mechanism to vacuumize the transition branch after the current deposition process is finished, then opening the control valve to make the cleaning device move in the pipe and clean the pipe.

[0024] In some embodiments, the pipe system further comprises:

[0025] an air inlet pipe connected to the transition branch and provided with a first valve;

[0026] an air outlet pipe connected to the transition branch and provided with a second valve;

[0027] a filtering assembly connected to the air outlet pipe for filtering the mixed gas discharged from the air outlet pipe.

[0028] In a third aspect, the present application further provides a pipe foreign matter cleaning method, comprising:

[0029] when the flow in the pipe does not meet the setting, vacuumizing the transition branch connected to the pipe 5 after the current deposition process is finished, then opening the control valve between the pipe and the transition branch to make the cleaning device in the transition branch enter the pipe, and make the cleaning device move in the pipe and clean the pipe.

[0030] In some embodiments, the control valve is opened after a set time of maintaining the state of zero flow in the pipe after the current deposition is finished.

[0031] In some embodiments, the control valve is closed after the cleaning device enters the pipe.

[0032] In some embodiments, the control valve is closed after the cleaning device returns to the transition branch after the pipe cleaning is completed, air is introduced into the transition branch through the air inlet pipe connected with the transition branch, and the mixed gas in the transition branch is discharged through the air outlet pipe connected with the transition branch.

[0033] The technical scheme provided by the present application has the beneficial effects of:

[0034] The pipe foreign matter cleaning device provided by the embodiments of the present application is arranged in the transition branch connected with the pipe. When the deposition process is normally performed, the transition branch and the pipe are separated by the control valve between the transition branch and the pipe, the cleaning device in the transition branch does not affect the circulation of the acidic and toxic gas in the pipe, and the acidic and toxic gas required for manufacturing the optical fiber preform can be normally circulated and transported in the pipe.

[0035] When the pipe needs to be cleaned, after the current deposition process is finished and the acidic and toxic gas is not transported in the pipe, the transition branch is first vacuumized, the control valve is then opened to connect the transition branch and the pipe, the transition branch is vacuumized

[0036] to avoid air entering the pipe, and the purity of the gas in the pipe is ensured to avoid affecting the quality of the optical fiber preform manufactured subsequently. After the control valve is opened, the cleaning device is controlled by the control module to enter the pipe and move in the pipe to clean the pipe.

[0037] After the cleaning is completed, the cleaning device returns to the transition branch, and the control valve is closed to separate the transition branch and the pipe, and then the next deposition process can be performed. During the entire cleaning process, the pipe does not need to be disassembled or replaced, only the vacuumization operation of the transition branch and the operation of controlling the cleaning device to enter the pipe and move in the pipe are needed.

[0038] The pipe cleaning work is simple and efficient, the cleaning time is shortened, the influence on the production efficiency is reduced, and the pipe always maintains the state of being isolated from the outside, that is, the pipe transporting the acidic and toxic gas always maintains the closed state.

[0039] The danger of personnel contacting the corrosive, acidic and toxic gas can be avoided, and the air or impurities from the outside cannot enter the pipe, so the quality of the optical fiber preform manufactured subsequently is not affected. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0044] 0In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the following will be described with reference to the embodiments

[0045] The drawings in the embodiments of the present application are used to clearly and completely describe the technical solutions in the embodiments of the present application, and obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.

[0046] The embodiments of the present application provide a pipeline foreign matter cleaning device, a pipeline system and a pipeline foreign matter cleaning method, which can solve the problems that the current cleaning of the pipeline of acidic and toxic gas consumes production time, affects production efficiency, and has the risk of contacting corrosive and acidic and toxic gas.

[0047] Referring to Figure 1 As shown in the figure, the pipeline 2 foreign matter cleaning device 4 provided by the present application comprises a cleaning device 4, a vacuumizing mechanism 6 and a control module 5, wherein the cleaning device 4 is arranged in the transition branch 1 connected with the pipeline 2, the vacuumizing mechanism 6 is connected with the transition branch 1, and the control module 5 is used to control the vacuumizing mechanism 6 to vacuumize the transition branch 1 after the current deposition process is finished when the flow in the pipeline 2 does not meet the setting, and then open the control valve 3 between the pipeline 2 and the transition branch 1, so that the cleaning device 4 moves in the pipeline 2 and cleans the pipeline 2.

[0048] Referring to Figure 1As shown, specifically, the cleaning device 4 includes a ball, the surface of the ball is uniformly covered with bristles, and the bristles make the ball not directly contact with the inner wall of the pipeline 2, and a strip-shaped permanent magnet is arranged in the ball, and the two ends of the permanent magnet are N pole and S pole respectively.

[0049] Referring to Figure 1 As shown, further, a driving mechanism 7 is arranged outside the pipeline 2, for driving the cleaning device 4 to move in the pipeline 2; specifically, the driving mechanism 7 includes two annular electromagnets 71, the electromagnets 71 are arranged around the pipeline 2 and the N pole and S pole are distributed along the axial direction of the pipeline 2, and the cleaning device 4 is arranged between the two electromagnets 71 and the N pole and S pole of the permanent magnet are also distributed along the axial direction of the pipeline 2; when the magnetic pole directions of the two electromagnets 71 are the same, the two electromagnets 71 generate repulsive forces with opposite directions to the permanent magnet, at this time, the electromagnets 71 are subjected to the magnetic forces of the two electromagnets 71 and are in a balanced state between the two electromagnets 71, and the magnetic forces of the two electromagnets are relatively large, so that the balanced state is relatively stable; when the magnetic pole directions of the two electromagnets 71 are opposite, the two electromagnets 71 generate attractive force and repulsive force with the same direction to the permanent magnet respectively, at this time, the permanent magnet moves to the direction of the electromagnet 71 which generates the attractive force, and after the force balance is maintained, the magnetic force of the other electromagnet 71 decreases, so that the stability of the force balance state is poor and is easy to be affected by external force to rotate.

[0050] By using the above principle, a track 72 along the axial direction of the pipeline 2 is arranged outside the pipeline 2, a base 73 is installed on the track 72, the two electromagnets 71 are installed on the base 73, and a linear drive motor is installed on the track 72 to drive the base 73 to move along the axial direction of the pipeline 2, the magnetic force of the two electromagnets 71 makes the ball move in the pipeline 2, when the ball enters the pipeline 2 from the transition branch 1 and moves away from the transition branch 1, the current directions of the two electromagnets 71 are opposite, the magnetic pole directions are opposite, and the balance stability of the permanent magnet is poor, so that the ball is subjected to resistance when encountering foreign matter in the pipeline 2, the resistance can make the ball rotate, the ball continues to move to the end of the pipeline 2 after passing the foreign matter; then the current directions of the two electromagnets 71 are the same, the magnetic pole directions are the same, at this time, the stability of the permanent magnet and the ball is high, then the ball moves to the transition branch 1, is not easy to rotate due to the resistance of the foreign matter when encountering the foreign matter, and can brush the foreign matter from the pipeline 2, and the foreign matter is cleaned into the transition branch 1 when the ball moves to the transition branch 1, and the cleaning of the foreign matter in the pipeline 2 is completed.

[0051] Referring to Figure 1As shown, further, in order to determine whether the pipeline 2 is cleaned, the electromagnet 71 is installed on the base 73, a pressure seat 74 is fixed on the base 73, the electromagnet 71 far away from the transition branch 1 is installed on the pressure seat 74, and a pressure sensor 75 is arranged between the electromagnet 71 and the pressure seat 74. When the magnetic poles of the two electromagnets 71 are in the same direction and the ball moves towards the transition branch 1, if foreign matter is encountered, the ball will move towards the electromagnet 71 far away from the transition branch 1, at this time, the magnetic force acting on the electromagnet 71 becomes larger, and the value of the pressure sensor 75 becomes larger. When the pipeline 2 moves normally without foreign matter, the magnetic force value remains at a set value. The pressure sensor 75 is connected with the control module 5, so as to determine whether the foreign matter is cleaned according to the pressure value change of the pressure sensor 75. If the cleaning is complete, the value does not change, the cleaning device 4 moves into the transition branch 1 and the control valve 3 is closed. If the value becomes larger, it indicates that the cleaning is not complete, at this time, the cleaning needs to be performed again until the pipeline 2 is cleaned.

[0052] Referring to Figure 1 As shown, further, in order to monitor the position of the cleaning device 4 in real time, a positioner is installed on the ball, and the positioner is wirelessly connected with the control module 5.

The controller 62 controls the operation of the vacuum pump 61 and detects the vacuum degree in the transition branch 1. The controller 62 is connected with the control module 5, the control module 5 controls the opening and closing of the vacuum pump 61 through the controller 62, and the controller 62 sends a vacuumizing completion instruction to the control module 5 when detecting that the vacuum degree in the transition branch 1 reaches a set value.

[0054] Referring to Figure 1 As shown, further, the control module 5 is connected with the pipeline 2, which is also used for monitoring the flow data in the pipeline 2, and sending a cleaning signal when the flow in the pipeline 2 does not meet the set value. Specifically, the flow in the pipeline 2 is usually set to a certain value in 20-50 SLM. When the control module 5 detects that the flow in the pipeline 2 is unstable and the flow value fluctuates up and down around the set value, data analysis is performed to determine that the pipeline 2 is blocked by foreign matter, and a signal is sent to clean the pipeline 2. When the flow in the pipeline 2 is 0 for more than a set time after the current deposition process is completed, the pipeline 2 is cleaned.

[0055] Referring to Figure 1As shown, during cleaning, the control module 5 sends a signal to the controller 62 to control the vacuum pump 61 to vacuum the transition branch 1, when the vacuum degree in the transition branch 1 reaches -1 KPa, the controller 62 sends a vacuum completion instruction to the control module 5, the control module 5 determines that the data is correct and opens the control valve 3, and controls the cleaning device 4 to enter the pipeline 2, after the cleaning device 4 completely passes through the control valve 3, the control valve 3 is closed, the cleaning device 4 is guided to reciprocate in the pipeline 2 by the driving mechanism 7 to clean the pipeline 2, after cleaning is completed, the control valve 3 is opened, the cleaning device 4 is controlled to return to the transition branch 1, and after the control module 5 detects that the position of the cleaning device 4 is at the original point, the control valve 3 is closed, and it is prompted that the equipment can be normally operated.

The foreign matter cleaning assembly 8 includes an air inlet pipe 81, an air outlet pipe 82 and a filter assembly 83, wherein the air inlet pipe 81 and the air outlet pipe 82 are both connected to the transition branch 1, the first valve is arranged on the air inlet pipe 81, the second valve is arranged on the air outlet pipe 82, and the filter assembly 83 is connected to the air outlet pipe 82 for filtering mixed gas discharged from the air outlet pipe 82.

[0057] Referring to Figure 1 As shown, specifically, the filter assembly 83 includes a shell and filter cotton arranged in the shell, the shell is communicated with the air outlet pipe 82, during cleaning of the pipeline 2, the first valve and the second valve are both closed to smoothly complete vacuuming of the transition branch 1; during cleaning of the transition branch 1, the first valve and the second valve are opened, the air inlet pipe 81 is connected to the nitrogen pipeline 2, nitrogen is blown into the transition branch 1 through the air inlet pipe 81, the nitrogen is mixed with the foreign matter of the pipeline 2 brought into the transition branch 1 by the cleaning device 4, is discharged through the air outlet pipe 82, and is filtered through the filter cotton, the filtered waste gas is discharged into a waste gas treatment device for harmless treatment, the foreign matter of the pipeline 2 is left on the filter cotton, the filter cotton can be taken out by the staff and the foreign matter is separated, the foreign matter of the pipeline 2 is sampled and analyzed, and the analysis structure is updated to a database to prompt the staff to determine the source of the foreign matter; according to the analysis result of the foreign matter, the source of the foreign matter can be finally determined, so that the foreign matter is eliminated or reduced from the source, and is compared and analyzed with the next cleaning, if it is determined that the analysis result has foreign matter affecting product quality, the production is stopped, and the occurrence of defective products is limited.

[0058] In a second aspect, the embodiment of the present application further provides a pipeline system, which includes a pipeline 2, a transition branch 1, a control valve 3 and a pipeline foreign matter cleaning device as described above.

[0059] Referring to Figure 1As shown, in particular, in the embodiment, the pipeline 2 is in a straight line type, the transition branch 1 is connected to the end of the pipeline 2, and the transition branch 1 is coaxial with the pipeline 2, the end of the transition branch 1 away from the pipeline 2 is closed, and the control valve 3 is arranged between the transition branch 1 and the pipeline 2.

[0060] Referring to Figure 1 As shown, in the pipeline foreign matter cleaning device, the vacuumizing mechanism 6 is connected to the transition branch 1, the cleaning device 4 is arranged in the transition branch 1, and the control module 5 is arranged on the pipeline 2 and is used to control the vacuumizing mechanism 6 to vacuumize the transition branch 1 after the current deposition process is completed when the flow in the pipeline 2 does not meet the setting, and then open the control valve 3 to make the cleaning device 4 move in the pipeline 2 and clean the pipeline 2.

[0061] Referring to Figure 1 As shown, in the pipeline foreign matter cleaning device, the air inlet pipe 81 and the air outlet pipe 82 are both connected to the transition branch 1, the first valve is arranged on the air inlet pipe 81, the second valve is arranged on the air outlet pipe 82, and the filtering assembly 83 is connected to the air outlet pipe 82 and is used to filter the mixed gas discharged from the air outlet pipe 82.

[0062] In a third aspect, the application also provides a pipeline foreign matter cleaning method, which is cleaned by using the pipeline foreign matter cleaning device as described above.

[0064] When deposition is performed, the acid and toxic gas normally flows in the pipeline 2, and the flow in the pipeline 2 is the set value, and the control module 5 monitors the flow data in the pipeline 2 in real time; when it is monitored that the flow in the pipeline 2 is unstable (the actual flow in the pipeline 2 fluctuates under the set flow), the control module 5 determines that the pipeline 2 needs to be cleaned, and the determination result is fed back to the controller 62, and the flow in the pipeline 2 is 0 for more than 30 minutes after the current deposition is completed, and the cleaning is started.

[0065] When the cleaning is started, the controller 62 controls the vacuum pump 61 to be opened to vacuumize the transition branch 1, and detects the vacuum degree in the transition branch 1, and when the vacuum degree value reaches -1 KPa, the vacuum completion instruction is fed back to the control module 5, the control module 5 opens the control valve 3 after determining that the data is correct, and after the control valve 3 is opened, the control module 5 controls the driving mechanism 7 to be started, the driving mechanism 7 guides the cleaning device 4 to move from the transition branch 1 to the pipeline 2, and monitors the position of the cleaning device 4 in real time, and when the cleaning device 4 completely passes through the control valve 3, the control valve 3 is closed, and the driving mechanism 7 guides the cleaning device 4 to reciprocally move in the pipeline 2 to clean the pipeline 2.

[0066] In the cleaning, according to the pressure data of the pressure sensor 75, it is judged whether the pipeline 2 is cleaned or not, specifically, the cleaning device 4 is moved in the pipeline 2 for three times, then it is judged whether the value of the pressure sensor 75 is changed when the cleaning device 4 is moved to the transition branch 1 for the third time, if not, the cleaning device 4 is moved to the transition branch 1, the control valve 3 is closed, and after the position of the cleaning device 4 is detected, the control module 5 prompts that the equipment can be normally operated; if the value of the pressure sensor 75 is changed when the cleaning device 4 is moved to the transition branch 1 for the third time, the pipeline 2 is not cleaned, it needs to be cleaned again, and the control module 5 prompts the abnormality and records, which is helpful for the analysis of foreign matters, until the value of the pressure sensor 75 is not changed when the cleaning device 4 is moved to the transition branch 1, the cleaning of the pipeline 2 is completed.

[0067] After the pipeline 2 is cleaned, the cleaning device 4 is moved to the transition branch 1, the control module 5 judges that the position of the cleaning device 4 is at the original point, then the control valve 3 is closed, and the equipment can be normally operated.
