Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a belt conveyor roller bearing lubrication system. Background Art

[0002] In the belt conveyor, the roller is the core execution unit and redirection unit of the transmission, which is an important indicator of whether the belt conveyor can operate normally. The normal operation of the roller bearing is crucial to the performance and life of the roller. Good lubrication can reduce friction, wear, reduce heat, and improve the working efficiency and life of the bearing. However, the traditional lubrication method cannot determine the amount of grease in the oil chamber, and it is impossible to determine when to add the appropriate amount of grease; it is impossible to determine whether the grease in the oil chamber contains too many impurities, and it is forced to stop only when the bearing makes abnormal noise, overheats or is damaged. When the lubrication is insufficient, it will cause rapid wear of the bearing; when the lubrication is too much, it will increase the running resistance; when there are too many impurities in the grease, the bearing will be damaged faster. Once there is a problem with the bearing, the roller needs to be removed from the belt conveyor. This removal process is time-consuming and labor-intensive, has a great impact on production and operation, and greatly reduces the economic benefits of the enterprise. Summary of the invention

The central processing unit 1 adopts a common structure in the prior art such as an advanced microprocessor or a programmable controller, which will not be described one by one here.

[0045] The inert gas used in this embodiment is argon, carbon dioxide, etc.

[0046] The process of lubricating the roller bearing of the belt conveyor roller bearing lubrication system of the present invention is described in detail as follows:

[0047] The clearance volumes of bearing A 10, bearing B 24, and bearing C 37 are detected in sequence.

[0048] When measuring the void volume of bearing A10, the central processor 1 issues an instruction to measure the void volume of bearing A10, the gas injection pump 29 is started, and the inert gas is pumped out from the gas storage tank 28. The gas pressure is adjusted by the pressure regulator C30, and the flow is controlled by the flow control valve C31. The inert gas is diverted to the gas injection branch pipeline A through the multi-way diverter C32. It enters the gas injection hole A through the two-way diverter A7 and enters the bearing A10. The air inside the bearing A10 is slowly discharged from the exhaust hole A, the inert gas continues to flow in, and then the inert gas is discharged through the exhaust hole A, and the concentration of the discharged inert gas is detected using the gas concentration detection device A14. The gas concentration detection device A14 can use a gas chromatograph to measure the concentration of the inert gas by gas chromatography. When the comparison shows that the inert gas concentration exceeds 90%, it is considered that the bearing A10 is filled with inert gas. The space in the bearing A10 is converted by flow and pressure to determine the amount of grease consumed by the bearing A10 per day. This data is fed back to the central processor 1 through an electrical signal to determine the filling amount and filling cycle of the grease. The gas chromatograph is an outsourced component and belongs to the prior art. Its structure and working principle are common knowledge to those skilled in the art and will not be described in detail here.

[0049] After the measurement is completed, the gas injection pump 29 is turned off under the instruction of the central processor 1.

[0050] When measuring the void volume of bearing B 24, the central processor 1 issues an instruction to measure the void volume of bearing B, the gas injection pump 29 is started, and the inert gas is pumped out from the gas storage tank 28. The gas pressure is adjusted by the pressure regulator C 30, and the flow is controlled by the flow control valve C 31. The inert gas is diverted to the gas injection branch pipe B through the multi-way diverter C32. It enters the gas injection hole B and enters the bearing B 24 by flowing through the two-way diverter B 20. The air inside the bearing B 24 is slowly discharged from the exhaust hole B, the inert gas continues to flow in, and then the inert gas is discharged through the exhaust hole B, and the gas concentration detection device B 23 is used to detect the concentration of the discharged inert gas. The gas concentration detection device B23 can use a gas chromatograph to measure the concentration of the inert gas by gas chromatography. When the comparison shows that the inert gas concentration exceeds 90%, it is considered that the bearing B24 is filled with inert gas. The space in the bearing B24 is converted by flow rate and pressure to determine the amount of grease consumed by the bearing B24 per day. This data is fed back to the central processor 1 through an electrical signal to determine the filling amount and filling cycle of the grease. The gas chromatograph is an outsourced component and belongs to the prior art. Its structure and working principle are common knowledge to those skilled in the art and will not be described in detail here.

[0051] After the measurement is completed, the gas injection pump 29 is turned off under the instruction of the central processor 1.

[0052] When measuring the void volume of the bearing C 37, the central processor 1 issues an instruction to measure the void volume of the bearing C 37, the gas injection pump 29 is started, the inert gas is pumped out from the gas storage tank 28, the gas pressure is adjusted by the pressure regulator C 30, and the flow is controlled by the flow control valve C 31. The inert gas is diverted to the gas injection branch pipeline C through the multi-way diverter C 32. It flows through the two-way diverter C 33 and enters the gas injection hole C and enters the bearing C 37. The air inside the bearing C 37 is slowly discharged from the exhaust hole C, the inert gas continues to flow in, and then the inert gas is discharged through the exhaust hole C, and the gas concentration detection device C 36 is used to detect the concentration of the discharged inert gas. The gas concentration detection device C36 can use a gas chromatograph to measure the concentration of the inert gas by gas chromatography. When the comparison shows that the inert gas concentration exceeds 90%, it is considered that the bearing C37 is filled with inert gas. The space in the bearing C37 is converted by flow rate and pressure to determine the amount of grease consumed by the bearing C37 per day. This data is fed back to the central processor 1 through an electrical signal to determine the filling amount and filling cycle of the grease. The gas chromatograph is an outsourced component and belongs to the prior art. Its structure and working principle are common knowledge to those skilled in the art and will not be described in detail here.

[0053] After the measurement is completed, the gas injection pump 29 is turned off under the instruction of the central processor 1.

[0054] When bearing A10, bearing B24, or bearing C37 needs to be greased, the grease pump only greases one of bearing A10, bearing B24, or bearing C37 at a time.

[0055] When it is necessary to inject grease into bearing A10, the central processor 1 issues a command to inject grease into bearing A10, the grease injection pump 3 starts, extracts grease from the grease storage tank 2, adjusts the injection pressure through the pressure regulator A4, and then quantitatively injects grease through the flow control valve A5. The grease is diverted to the grease injection pipeline A through the multi-way diverter A6, and then flows through the three-position four-way valve A7 and the grease injection pressure sensor A8 into the bearing A10, completing the grease injection of the bearing A10.

[0056] When it is necessary to inject grease into bearing B 24, the central processor 1 issues a command to inject grease into bearing B 24, the grease injection pump 3 starts, extracts grease from the grease storage tank 2, adjusts the injection pressure through the pressure regulator A 4, and then quantitatively injects grease through the flow control valve A 5. The grease is diverted to the grease injection pipeline B through the multi-way diverter A 6, and then flows through the three-position four-way valve B 21 and the grease injection pressure sensor B 22 to enter the bearing B 24, completing the grease injection of the bearing B 24.

[0057] When it is necessary to inject grease into the bearing C37, the central processor 1 issues a command to inject grease into the bearing C37, the grease injection pump 3 starts, extracts grease from the grease storage tank 2, adjusts the injection pressure through the pressure regulator A4, and then quantitatively injects grease through the flow control valve A5. The grease is diverted to the grease injection pipeline C through the multi-way diverter A6, and then flows through the three-position four-way valve C34 and the grease injection pressure sensor C35 to enter the bearing C37, completing the grease injection of the bearing C37.

[0058] The bearing A10, the bearing B24, and the bearing C37 are greased as needed. The bearing A10, the bearing B24, and the bearing C37 are not greased at the same time, but at different times.

[0059] After the belt conveyor has been working for a certain period of time, a large amount of impurities may be mixed in the grease. In order to effectively protect bearing A10, bearing B 24, and bearing C 37 and make bearing A10, bearing B 24, and bearing C 37 work safely and reliably, it is necessary to check whether the grease of bearing A10, bearing B 24, and bearing C 37 needs to be replaced.

[0060] When checking whether the bearing A10 needs to be replaced with grease, open the electric gate valve A11, and the grease overflows to the overflow tank A12. After the grease is taken out, it can be evenly scraped on a clean white cloth. Based on the experience of the staff, observe the impurity particles in the grease or the degree of change in the color of the grease to determine whether the grease in the bearing A10 needs to be replaced. Of course, other conventional methods can also be used to determine whether the grease needs to be replaced, which will not be introduced here one by one.

[0061] When it is determined that bearing A10 contains a large amount of impurities and needs to be cleaned and grease replaced, the central processor 1 issues a command to inject cleaning liquid into bearing A10. The injection pump 16 starts to pump cleaning liquid from the liquid storage tank 15, adjusts the injection pressure through the pressure regulator B17, and then controls the flow through the flow control valve B18. The cleaning liquid is diverted to the injection branch pipeline A through the multi-way diverter B19. Then it passes through the three-position four-way valve A8 and flows through the grease injection pressure sensor A9, enters the bearing A10, and at the same time opens the electric gate valve A11, and the grease and cleaning liquid in the bearing A10 flow into the overflow tank A12.

[0062] After the cleaning of bearing A10 is completed, some cleaning liquid may remain in bearing A10. If it is only evaporated naturally, it will take a long time and be inefficient. If it is not treated, re-adding grease will reduce the viscosity of the grease and fail to play a good lubricating role. At the same time, the corrosion of bearing A10 will increase due to excessive water in the residual cleaning liquid. After the central processor 1 issues an instruction to empty the cleaning liquid, the air injection pump 29 is started, and the inert gas enters the grease injection pipeline A of bearing A10 through the multi-way diverter C 32, the two-way diverter A 7, and the three-position four-way valve A 8, and the cleaning liquid remaining in the grease injection pipeline A and the bearing A10 is discharged, and the inner wall of the grease injection pipeline A and the inside of the bearing A10 are blown dry, thereby ensuring that when the bearing A10 is greased again, the water in the residual cleaning liquid will not affect the consistency of the grease and corrode the bearing A10.

[0063] When checking whether the bearing B 24 needs to be replaced with grease, open the electric gate valve B 25, and the grease overflows into the overflow tank B 26. The grease can be taken out and evenly scraped on a clean white cloth. Based on the experience of the staff, observe the impurity particles in the grease or the degree of change in the color of the grease to determine whether the grease in the bearing B 24 needs to be replaced. Of course, other conventional methods can also be used to determine whether the grease needs to be replaced, which will not be introduced here one by one.

[0064] When it is determined that bearing B 24 contains a large amount of impurities and needs to be cleaned and grease replaced, the central processor 1 issues a command to inject cleaning liquid into bearing B. The injection pump 16 is started to pump cleaning liquid from the liquid storage tank 15, and the injection pressure is adjusted by the pressure regulator B17, and then the flow is controlled by the flow control valve B19. The cleaning liquid is diverted to the injection branch pipeline B through the multi-way diverter B19. Then it passes through the three-position four-way valve B 21 and flows through the grease injection pressure sensor B 22, and enters the bearing B 24. At the same time, the electric gate valve B25 is opened, and the grease and cleaning liquid in the bearing B 24 flow into the overflow tank B 26.

[0065] After the cleaning of bearing B 24 is completed, some cleaning liquid may remain in bearing B 24. If it is only evaporated naturally, it will take a long time and be inefficient. If it is not treated, adding grease again will reduce the viscosity of the grease and fail to play a good lubricating role. At the same time, the corrosion of bearing B 24 will increase due to the excessive water in the residual cleaning liquid. The central processor 1 issues an instruction to empty the cleaning liquid, and the gas injection pump 29 is started to pass the inert gas through the multi-way diverter C 32, the two-way diverter B 20, and the three-position four-way valve B 21 into the grease injection branch pipeline B of bearing B 24, discharge the cleaning liquid remaining in the grease injection branch pipeline B and bearing B 24, and blow dry the inner wall of the grease injection branch pipeline B and the inside of bearing B 24, so as to ensure that when bearing B 24 is greased again, the residual cleaning liquid will not affect the consistency of the grease and corrode bearing B 24.

[0066] When checking whether the bearing C 37 needs to be replaced with grease, open the electric gate valve C 38, and the grease overflows into the overflow tank C 39. After the grease is taken out, it can be evenly scraped on a clean white cloth. Based on the experience of the staff, observe the impurity particles in the grease or the degree of change in the color of the grease to determine whether the grease in the bearing C 37 needs to be replaced. Of course, other conventional methods can also be used to determine whether the grease needs to be replaced, which will not be introduced here one by one.

[0067] When it is determined that bearing C 39 contains a large amount of impurities and needs to be cleaned and grease replaced, the central processor 1 issues a command to inject cleaning liquid into bearing C 27. The injection pump 16 is started to pump cleaning liquid from the liquid storage tank 15, and the injection pressure is adjusted by the pressure regulator B17, and then the flow is controlled by the flow control valve B18. The cleaning liquid is diverted to the injection branch pipeline C through the multi-way diverter B19. Then it passes through the three-position four-way valve C 34 and flows through the grease injection pressure sensor C 35, entering the bearing C 37, and at the same time, the electric gate valve C 38 is opened, and the grease and cleaning liquid in the bearing C 37 flow into the overflow tank C 39.

[0068] After the bearing C37 is cleaned, some cleaning liquid may remain in the bearing C37. If it is only evaporated naturally, it will take a long time and be inefficient. If it is not treated, adding grease again will reduce the viscosity of the grease and fail to play a good lubricating role. At the same time, the excessive water in the residual cleaning liquid will increase the corrosion of the bearing C37. The central processor 1 issues an instruction to empty the cleaning liquid, and the gas injection pump 29 is started to pass the inert gas through the multi-way diverter C32, the two-way diverter C33, and the three-position four-way valve C34 into the grease injection pipeline C of the bearing C37, discharge the cleaning liquid remaining in the grease injection pipeline C and the bearing C37, and blow dry the inner wall of the grease injection pipeline C and the inside of the bearing C37, so as to ensure that when the bearing C37 is greased again, the residual cleaning liquid will not affect the consistency of the grease and corrode the bearing C37.

[0069] After the belt conveyor roller bearing lubrication system of the present invention has been working for a period of time, when the central processor 1 issues a grease injection instruction to the bearing A10, if it is detected that the value of the grease injection pressure sensor A9 increases abnormally, it indicates that the bearing A10 is blocked. At this time, the central processor 1 issues an instruction to start the gas injection pump 29, and the gas opens to the three-position four-way valve A8 when flowing through the two-way diverter A7, and then the inert gas directly passes through the grease injection hole A of the bearing A10 and enters the shaft A10, and the pulse impact is unblocked. If it is detected that the value of the pressure regulator A4 increases abnormally, it indicates that the grease injection main line is blocked. At this time, the inert gas is pumped back to the grease injection branch line A and the grease injection main line through the three-position four-way valve A8, and the grease is pumped back to the grease storage tank 2 through repeated pulse impacts, thereby unblocking the grease injection main line.

[0070] When the central processor 1 issues a grease injection command to the bearing B 24, if the value of the grease injection pressure sensor B 22 is detected to increase abnormally, it means that the bearing B 24 is blocked. At this time, the central processor 1 issues a command to start the gas injection pump 29. When the gas flows through the two-way diverter B 20, it opens to the three-position four-way valve B 21, and then the inert gas directly passes through the grease injection hole B of the bearing B 24 and enters the bearing B 24, and the pulse impact is unblocked. If the value of the pressure regulator A 4 is detected to increase abnormally, it means that the grease injection main line is blocked. At this time, the inert gas is pumped back to the grease injection branch line B and the grease injection main line through the three-position four-way valve B 21, and the grease is pumped back to the grease storage tank 2 through repeated pulse impacts, thereby unblocking the grease injection main line.

[0071] When the central processor 1 issues a grease injection command to the bearing C 37, if the value of the grease injection pressure sensor C 35 is detected to increase abnormally, it means that the bearing C 37 is blocked. At this time, the central processor 1 issues a command to start the gas injection pump 29. When the gas flows through the two-way diverter C 33, it opens to the three-position four-way valve C 34, and then the inert gas directly passes through the grease injection hole C of the bearing C 37 and enters the bearing C 37, and the pulse impact is unblocked. If the value of the pressure regulator A 4 is detected to increase abnormally, it means that the grease injection main line is blocked. At this time, the inert gas is pumped back to the grease injection sub-line C and the grease injection main line through the three-position four-way valve C 34, and the grease is pumped back to the grease storage tank 2 through repeated pulse impacts, thereby unblocking the grease injection main line.
